Release: Verify SVN deployment after publication

[ciampo]

Closes #55295. Closes #79804. Related: #79919.

What?

Verify the complete SVN deployment before reporting a release as successful, including when SVN reports a publish error or the release tag already exists.

Why?

The 23.9.0 upload failed with E160013: '/gutenberg' path not found after SVN had committed both trunk and the tag in revision 3678189. All 2,181 files match the release ZIP after applying the workflow's stable-tag substitution and changelog artifact. This matches the failure pattern reported in both issues; the underlying SVN server or network cause remains unconfirmed.

How?

Share the publication logic between trunk and tag-only uploads. After publication, export each required path at the same SVN revision and compare all paths and file contents against the prepared release. Retry verification for up to 15 minutes, with a fresh revision per attempt and bounded SVN reads.

Only a complete match succeeds. Missing, different, or unreadable content remains a failure. Existing tags receive the same verification, and uncertain writes are never repeated automatically. The verified revision appears in the logs and job summary.

This retains the atomic trunk-and-tag commit. #79919 separately proposes changing the upload strategy. Verification covers SVN contents; WordPress.org ZIP generation and distribution can finish later.

Testing Instructions

Run bash tools/release/test/publish-to-svn.sh on Linux with Subversion and GNU diff/timeout installed. The tests use disposable local SVN repositories and need no WordPress.org credentials.

They cover successful publication, a committed transaction followed by a simulated failed response, identical existing releases, missing or different files despite matching version headers, failed and stalled reads, delayed content visibility, tag-only releases, and concurrent changes that must not produce a match across different revisions. The new CI job runs this suite.

Validation

• Reproduced the failed-response case with the previous publication commands.
• Verified the 23.9.0 SVN trunk and tag at revision 3678189 against the release ZIP and original workflow changelog artifact.
• Full build, ShellCheck, and Actionlint passed.
• No production release was triggered or SVN content changed during testing.
