check_project_rules.py only checks fences + local links, so a bold marker that
CJK punctuation stops from rendering (e.g. `**（配比）**相互交织` — the closer is
preceded by punctuation and followed by a letter, so it can't close and the
asterisks print literally) would pass this repo's own CI. That class of bug had
to be swept out of every book by hand; nothing here was watching for it.
Adds check_emphasis.py — a standalone gate (identical across all books) that
runs CommonMark's flanking + process-emphasis rules and flags markers that
print literally or silently bold the wrong span. The ci.yaml content step now
runs it right after check_project_rules.py. Verified clean on this book.
The mdPress PDF step drives headless Chrome, which intermittently dies with
"websocket url timeout reached" plus dbus/bus.cc:405 errors. Confirmed by the
verbatim signature in six runs across five repos on 2026-07-22 and 07-23 — most
recently it failed a docker_practice smoke test after mdPress had already
finished parsing 196 chapters and assembling the HTML, dying only at step 5/5.
It is infrastructure, not content: a rerun clears it every time.
oc_guide already solved this with tools/build_pdf.py (bounded retries, process-
scoped timeout cleanup, per-attempt logs) and is notably absent from the flake
victims. This applies the same idea to the other 13 repos with a much smaller
change: shadow mdpress with a retry function once per run block, so every call
shape — including the multi-line continuations — is covered without rewriting
42 heterogeneous call sites. `command mdpress` reaches the real binary.
Fails closed: after 3 attempts the function returns 1 and errexit fails the
step. Verified all three paths against a fake mdpress before rollout — first-try
success, success after two flakes, and 3x failure aborting the step without
printing the following command.
oc_guide is untouched (it has no `mdpress build` call). Converging the other 13
onto its richer build_pdf.py remains the better long-term shape.
Per the author: mdPress should default to the latest release.
The cluster had drifted to three versions (0.7.10 x4, 0.7.11 x9, 0.7.14 x1),
and nine of those were pinned to bytes upstream had rebuilt under an existing
tag — the exact thing the harness move to 0.7.14 refused to do on principle.
Pinning also took CI down cluster-wide twice when a tag was rebuilt, because
the digest no longer matched. Latest is now 0.7.15; nothing was on it.
Each of the 43 install sites now resolves the newest release at build time by
following the /releases/latest redirect (no api.github.com call, so no
unauthenticated rate limit on shared runner IPs) and exports the version via
GITHUB_ENV.
Integrity is kept, not dropped: the archive is verified against that same
release's published checksums.txt, and a missing entry aborts the step rather
than passing silently. The honest trade-off is that this verifies the download
rather than pinning an immutable artifact — a rebuilt release is now followed
instead of failing the build. That is the intended behaviour here, since the
rebuild breakage was the problem being solved and upstream is the same author.
Tests updated in step: 12 suites asserted the literal MDPRESS_SHA256 as a
proxy for "this download is checksum-verified". They now assert checksums.txt,
which is where that guarantee lives.
A wedged Chrome/mdPress step held a harness runner for 27 minutes yesterday
(normal run: ~4 min) and ignored `gh run cancel`; it only stopped because that
job happened to carry timeout-minutes: 30. An audit found 66 of the 101 jobs
across the cluster had no timeout at all — the same hang there would have held
a runner for GitHub's 6-hour default.
Values come from measured run history, not guesses. Across ~120 successful
runs the slowest workflow tops out at 10 min (Update Preview Publications),
CI at 6.5, Update Preview PDF at 4.8:
30 min — jobs that run Chrome/mdPress/pandoc (3x the observed max, and the
value harness already used)
15 min — release, publish, deploy, check-link, chaincode-tests
10 min — dependabot auto-merge
Every value has at least 6x headroom over its job's observed maximum, so this
should never turn a slow-but-working run into a failure.
Verified: all 72 workflow files still parse, and all 101 jobs now carry an
integer timeout in range.
There might be a conflict between the new version node.js and this project's dependencies, according to CI Error message "error:0308010C:digital envelope routines::unsupported". Try to confirm and fix it by specifying the old styled openssl.
