* [PATCH v3] Provide relfilenode statistics

From: Bertrand Drouvot @ 2023-11-16 02:30 UTC (permalink / raw)

We currently don’t have writes counters for relations.
The reason is that we don’t have the relation OID when writing buffers out.
Tracking writes per relfilenode would allow us to track/consolidate writes per
relation.

relfilenode stats is also beneficial for the "Split index and table statistics
into different types of stats" work in progress: it would allow us to avoid
additional branches in some situations.

=== Remarks ===

This is a POC patch. There is still work to do: there is more places we should
add relfilenode counters, create more APIS to retrieve the relfilenode stats,
the patch takes care of rewrite generated by TRUNCATE but there is more to
care about like CLUSTER,VACUUM FULL.

The new logic to retrieve stats in pg_statio_all_tables has been implemented
only for the new blocks_written stat (we'd need to do the same for the existing
buffer read / buffer hit if we agree on the approach implemented here).

The goal of this patch is to start the discussion and agree on the design before
moving forward.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>
  0 siblings, 0 replies; 249+ messages in thread

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.

* [PATCH v6a 1/5] Add GitHub Actions workflow for CI
@ 2026-05-28 16:31 Nazir Bilal Yavuz <byavuz81@gmail.com>

From: Nazir Bilal Yavuz @ 2026-05-28 16:31 UTC (permalink / raw)

Cirrus CI, which the project has used to run CI, is shutting down on
June 1, 2026. Replace it with a GitHub Actions. Github Actions is
selected because it has unlimited runner time for public repositories.

Github Action currently covers:

- SanityCheck
- Linux (Autoconf)
- Linux (Meson, 32- and 64-bit)
- macOS (Meson)
- Windows (Visual Studio + Meson and MinGW + Meson)
- CompilerWarnings

BSD coverage is left for later, as it requires more work.

Back-branches will be updated later, after being sure that workflow runs
correctly on master.
