MercurialRepositoryTest.testBuildTagListOneMore fails on macOS

[vladak]

The MercurialRepositoryTest.testBuildTagListOneMore test has started failing recently on macOS with:

Error:  Failures: 
Error:    MercurialRepositoryTest.testBuildTagListOneMore:535->runHgCommand:196 hg command '[hg, tag, branch_tag]' failed.
exit code: 255
stdout:

stderr:
 ==> expected: <0> but was: <255>

Unfortunately the stderr seems to be empty.

The whole set of MercurialRepositoryTest passed Sep 9, 2025 and failed on Sep 17, 2025. There was a version bump from 7.1 to 7.1.1 however according to the release notes there does not seem to be anything relevant. Mercurial is installed from Homebrew.

Also, I cannot reproduce the issue locally on macOS Sequoia with Mercurial 7.1.1 installed from Homebrew.

The indirect cause is visible in the logs:

WARNING: Terminating process of command [hg tag branch_tag] in directory '/private/var/folders/q0/wmf37v850txck86cpnvwm_zw0000gn/T/source11119144795880528207/addedTagTest' due to timeout 30 seconds

Perhaps the command awaits user input ? (which would sort of make sense given that hg tag creates a commit and this might require a user account etc.)
