Subject: [PATCH 03/23] cirrus/ccache: disable compression and show stats
Date: Sun, 3 Apr 2022 00:10:20 -0500
Since v4.0, ccache enables zstd compression by default, saving roughly
2x-3x. But, cirrus caches are compressed as tar.gz, so we could disable
ccache compression, allowing cirrus to gzip the uncompressed data
(better than ccache's default of zstd-1).
With default compression enabled (https://cirrus-ci.com/task/6692342840164352):
linux/debian/bullseye has 4.2; 99MB cirrus cache; cache_size_kibibyte 109616
macos has 4.5.1: 47MB cirrus cache; cache_size_kibibyte 52500
freebsd has 3.7.12: 42MB cirrus cache; cache_size_kibibyte 134064
windows has 4.6.1; 180MB cirrus cache; cache_size_kibibyte 51179
todo: compiler warnings
With compression disabled (https://cirrus-ci.com/task/4614182514458624):
linux: 91MB cirrus cache; cache_size_kibibyte 316136
macos: 41MB cirrus cache; cache_size_kibibyte 118068
windows: 42MB cirrus cache; cache_size_kibibyte 134064
freebsd is the same
The stats should either be shown or logged (or maybe run with CCACHE_NOSTATS,
to avoid re-uploading cache tarball in a 100% cached build, due only to
updating ./**/stats).
Note that ccache 4.4 supports CCACHE_STATSLOG, which seems ideal.
freebsd, linux
