Notifications posted on pull requests now carry a marker naming their
source, as an HTML comment on their first line, which is invisible when
rendered. When posting, 'ci-pages-notify.bash' finds its own earlier
notifications with the same marker on that pull request, and deletes them.
A pull request therefore holds a single comment per source, rather than
accumulating one per run.
The superseded comments are not lost entirely. Each notification carries a
one line summary linking its report, stashed in an HTML comment, and the
notification superseding it inherits that summary, together with the
history the superseded one held itself, into a collapsed 'Workflow history'
section. That section therefore lists all the earlier reports, stays flat
however many runs a pull request sees, and holds no entry for the report
shown right above it.
The 'pr-notification' artifact is now uploaded via the new reusable
'upload-pr-notification' action, which validates the content the reporting
scripts produced, and records the source key and the pull request number
alongside it.
Fixes#8037
Belt-and-braces in case GitHub apt mirrors start acting up again: On any
successful apt install, cache the deb files downloaded/needed for the
step, so on next run the mirrors need not be consulted. (That is: trade
apt mirror access with GitHub cache access, which is more reliable)
These tend to hang for hours on occasion. Install all apt dependencies
via ci-install.bash, and add a hard timeout and retry for each attempt.
Also removed unnecessary man-db config (GitHub has this off by default
now) and ineffective install path exclusions.
Cache key isolation: Include the build flavour (ccwarn/asan/gcov) in the
build ccache key, so the coverage (gcov), asan, and RTLMeter
(ccwarn-off) configurations no longer share and thrash the single
'<runs-on>-<cc>' bucket, nor warm-start from each other's (near-useless)
caches.
Prune stale entries instead of a fixed size cap: After building/testing,
evict ccache entries this run did not touch (--evict-older-than, based
on the run's own duration). This bounds the saved cache to the current
working set, so CCACHE_MAXSIZE and CCACHE_LIMIT_MULTIPLE are no longer
needed and are removed (ccache falls back to its 5G default ceiling, but
is realistically much smaller).
ccache configuration:
- Drop CCACHE_COMPRESS (already the default in ccache 4.x).
- Add CCACHE_COMPILERCHECK=content, so a changed compiler mtime on a rebuilt
ephemeral runner image does not invalidate the whole restored cache.
- Hoist all ccache-related variables (CACHE_BASE_KEY, CCACHE_*, CXX) to the
workflow-level env.
Remove dead ccache scaffolding:
- reusable-lint-py: the job never compiles or caches; drop its ccache env.
- reusable-rtlmeter-run: remove the disabled persistent-cache step and its
storage variables; keep CCACHE_DISABLE=1, since caching must stay off to
keep RTLMeter timings representative.
Store test job ccache as artifacts for reuse
Code coverage and RTLMeter complete (concluding 'skipped') on branch
pushes where they do no work, and each completion fires the Pages
workflow_run trigger. Rebuilding and redeploying master's pages for
these no-op events is wasteful.
Gate the build job so a workflow_run whose upstream conclusion is
'skipped' does nothing; deploy and notify need build, so they
cascade-skip.
Route such no-op runs to their own throwaway concurrency group. In the
shared 'pages' group they would, as the newest queued run, cancel a
pending real run and then deploy nothing (concurrency keeps only the
in-progress and newest pending run). Real runs keep sharing 'pages' and
serialize as before.
Add retry to deploy step to reduce flakyness due to the Pages back end.
Fix trigger on workflow file changes.
