`report_job_log.py` hardcoded the word *failed* into the comment header. Every
caller guards the step with `if: failure()`, so it was true by construction --
until an unguarded probe in weblib-viewer#10 ran it on a job that passed, and
the successful run posted a comment reading as a failure report. Anyone
scrolling that PR would conclude the probe had failed.
The interesting uses of this script are exactly the ones that want
`if: always()`: a probe, or a job whose *output* is the point rather than its
exit code. Those all lied in the header.
`--status` now supplies the outcome. **The default is `failed`**, which is what
`if: failure()` means, so the four consuming repos are untouched -- a change in
required arguments would have broken all of them at once, since they take this
script from `@main`. `JOB_STATUS` in the environment does the same, matching how
every other argument here already reads its default from the Actions
environment.
`${{ job.status }}` yields `success`/`failure`/`cancelled`/`skipped` while a
human writing the flag reaches for `passed`/`failed`, so both spellings are
accepted and the expression can be passed straight through. An **unrecognised**
status goes into the header verbatim rather than being rejected: `argparse`'s
`choices=` would exit 2 on a value the table has not heard of, and the log --
the whole reason this script exists -- would never be posted. A reporter must
not become the thing that reports nothing.
The "no log file" note was status-dependent too; it claimed the step "failed
before the build started" regardless.
## Verified
`test_report_job_log.py`, new here: stdlib only and offline, posting to an
`http.server` on localhost that keeps what it is sent, so each test reads the
comment back. An exit status of 0 proves nothing -- the script deliberately
swallows HTTP errors so a failure to report cannot mask the failure being
reported. 21 tests, 0 skipped, 1.2s. Three of them drive the CLI as a
subprocess with only environment variables set, the way a workflow does.
Each check was shown to fire by injecting the fault and reverting it:
| injected fault | result |
|---|---|
| header hardcodes `failed` again (the original bug) | 10 failures |
| `DEFAULT_STATUS = "passed"` (would break the four callers) | 8 failures |
| unknown status raises, as `choices=` would | 2 errors |
| missing-log note keeps the failure wording | 1 failure |
| a stray `%` in the `--status` help text | 1 failure |
All five reverted; the file's checksum matches the pre-injection copy.
Also drops a tracked `__pycache__/report_job_log.cpython-313.pyc` and adds a
`.gitignore`. It was committed by accident in 061d8b2 and importing the module
from the tests rewrites it, so it would otherwise show up in every future diff
as stale bytecode of a file that had already changed.
