Subject: [pgjdbc/pgjdbc] PR #4118: build: tidy .gitattributes for generated files and java diffs
Date: Thu, 28 May 2026 16:43:50 +0000
Message-ID: <[email protected]> (raw)

## What

- Mark `messages_*.java`, `messages.pot`, and `.github/workflows/package-lock.json` as `linguist-generated` so GitHub collapses them in PR diffs and excludes them from language stats.
- Enable git's built-in `java` funcname patterns (`*.java diff=java`) for clearer hunk headers in local diffs.

## Why

The translation `messages_*.java` bundles and the `.pot` template are regenerated by the gettext tasks, so their diffs are pure noise on review (the `.pot` in particular churns its `#: src/...:NNN` source-line refs on every edit). The npm lockfile is the textbook `linguist-generated` case.

`.po` files are intentionally left untouched: they hold human-authored translations, so reviewers should still see those diffs.

## How to verify

- After merge, open a PR that touches translations and confirm the generated files appear collapsed on GitHub.
- `git diff` on a Java change now shows the enclosing method in the hunk header.
