Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The new smoke test may report a false failure when successive commits occur within the same second, reducing CI reliability without indicating a real interoperation problem. The PR is otherwise mergeable with owner awareness and should update the assertion to compare commit identity instead. Poem

Compare
Send/receive a single project through both the hgweb and hgresume servers, alternating protocols across three pushes so each server pulls and appends to store files the other last wrote. Covers that the two front the same repo consistently across protocols, which nothing exercised before. Verified against a local cluster: this does NOT reproduce the hgweb/hgresume file-ownership issue from #2590. Freshly-created repos get setgid, group-shared (660) store files owned by the shared www-data group, so hgresume-as-root and hgweb-as-www-data can each write the other's files; the test passes regardless of which user hgresume runs as. Documented inline so it isn't mistaken for a permissions guard. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

- Around line 118-119: Update the assertions around GetProjectLastCommit in
SendReceiveServiceTests to compare the returned tip node/hash rather than commit
timestamps. Follow the existing SendReceiveAfterProjectReset pattern and assert
that the tip node changes after each send/receive, avoiding Unix-second
precision issues while preserving the intended commit-advance checks.

Compare tip hashes instead of commit dates.
GetProjectLastCommit uses Unix-second precision, so commits in the same second can make BeAfter fail. Read the tip node and assert that it changes after each send/receive, as in SendReceiveAfterProjectReset (Lines 118–119 and 126–127).

FlakyIntegrationtest,CanSendReceiveInterleavingHgwebAndResumable, inSendReceiveServiceTests.What it does: sends/receives a single project through both the hgweb and hgresume servers, alternating protocols across three pushes (first → second → first). Each push forces the receiving server to pull the other's commit and append to the store files it wrote, checking the two front the same server-side repo consistently across protocols. It's a
[Theory]over both starting orders and asserts each push advances the project's last-commit date.Scope correction (important): this started as an attempt to guard the hgweb/hgresume file-ownership bug fixed in #2590, but verifying against a local cluster showed it does not reproduce that bug, and I don't want to imply otherwise:
660files owned by the sharedwww-datagroup.hgwebwrites aswww-data(Apache worker user);hgresumewrites as root, but root is in thewww-datagroup via the pod'sfsGroup: 33.hgresumeruns as — I confirmed the interleaved S/R passes withhgresumereverted to root.644, non-setgid dirs) only appears on seeded/imported repos, not newly-created ones. Reproducing the ownership bug would require forcing that non-group-shared layout, which a new project never has.This is therefore kept as a cross-protocol interop smoke test, not a permissions-regression guard, and that's documented inline so it isn't misread later.
Note for reviewers:
FlakyIntegration, needs the lexbox stack. The revision cache is intentionally not cleared between pushes (history only grows forward).Test plan
[Theory]rows pass (~1–2 min each).hgresumereverted to root — still passes, confirming (per the summary) that new repos' group-shared permissions make the test insensitive to hgresume's user. See inline comment.
