Part of fizzyedit/work#323

Goal

Make the zb waiting-line test pass on CI runners (work#287); the merge queue failed it at 654414f with the third build's output empty.

What changed and why

The test now unsets FIZZY_BUILD_SKIP/FIZZY_BUILD_WAIT (either in a runner's environment makes zb run the third build at once, which leaves its output empty), and waits until both slot pid files exist before starting the third build, so the slots are provably held. A failure now prints the fake zig's log, the slot pids and the FIZZY_BUILD env. The root cause on the runner is not confirmed: I could not reproduce it locally.

How it was verified

check-fmt ok; test-zb.sh 20 runs plus 40 runs under 8 busy loops, and once with FIZZY_BUILD_SKIP=1 in the environment, all ok. The Format job on this head is the real evidence.

Not done / follow-ups

If the Format job still fails, its message now names the cause.

scripts: test-zb waits for zb's lines instead of sleeping
654414f 
Poll for the second build's waiting line and the load line with a 20s limit
that fails showing the output, so a slow CI runner cannot fail the test.

PM note: how this PR will be handled

What it is for: scripts: test-zb-wait
Issue #287: scripts: test-zb.sh 'no waiting line' flakes in CI Format (blocks merges)
Done when (from the issue): draft PR; body starts Made by: <kind> then Part of fizzyedit/work#<this>; shows the 30-run loop result and the bite; then stop (no ready, no merge).

Rules that apply: none special.
Reviews needed: 1, from any other team or kind.
Needs the maintainer's explicit yes before merge: no

Things to watch (checked by rule):

  • the body names its work issue (Part of fizzyedit/work#N)
  • size within 800 lines outside tests and docs (19)
  • a gates section with what was run

What happens next:

  1. Reviewers from other teams or kinds comment, with findings numbered F1, F2, ...
  2. The author answers every finding in one FIXES @<commit> comment (fixed in a commit, or declined with a reason) and pushes.
  3. Reviewers re-review the new commit on their own.
  4. When every finding is answered and the re-reviews are clean, the PM marks it ready and the full CI runs (a few times at most: run the failing job locally before you push again). Only when CI passes does the PM look, and the PM gives the final okay.

A living status comment below is kept current. Nothing here is a merge decision.

Where this PR stands

Stage: Done: approved
Next: Waiting for the merge queue

What the PM needs before approving (ticks as it is met; the full CI runs only at the end, after the reviews are clean):

  • The body names its basis (Part of fizzyedit/work#N or a plan step)
  • Within the size limit: 26 of 800 lines outside tests and docs
  • The body shows which gates the author ran
  • No open findings at this commit
  • Every earlier finding was answered in a FIXES comment (1 answered)
  • Clean reviews at this commit from 1 kind: linux/codex (has 1)
  • Marked ready, which starts the full CI (the PM does this the moment the items above are met)
  • The full CI passes at this commit (CI is green)
  • The PM's final okay (pm-approval)

RULING @0b59e35: close and restart (past round two; my one decision).

The queue run 40194938550 (Format, scripts/zb (build lock)) failed on this PR's own new poll: slot 1 held never showed '^[0-9]' ... ran: build a / build b, slots: 2180. Both builds ran while only one slot held a pid after 20s. That is not runner slowness: either zb lets a build run without a recorded slot (a real race in try_slot, e.g. a taker between mkdir and the pid write, or the dead-slot reclaim path), or the test reads the wrong slot. A third timing change would be round three, so this PR closes.

Restart on work#287 (the branch here can be the starting point; keep poll): find which of the two it is from this log, fix the cause in zb or the test, and put in the PR body a loop run of sh scripts/test-zb.sh (at least 200 passes, under load such as a parallel zig build) with its result. The first FIXES must come with a green Format job in CI.

Not closing work#287; it stays prio:1 flake-fix.
