Summary

The container image build had no Cargo job limit, so on a many-core machine BuildKit ran dozens of rustc processes at once and exhausted the RAM (two OOM kills on a 32-thread workstation). This caps the Cargo jobs of every compiling stage with CARGO_BUILD_JOBS, default 4, overridable with --build-arg.

Closes #2853. The maintainer accepted the measured slowdown on the self-hosted runner (below) for acceptance criterion AC6; the specification still shows AC6 as TODO and is updated in the close-out after merge.

Changes

• Containerfile: ARG CARGO_BUILD_JOBS=4 plus ENV in the chef base stage (every stage that compiles Rust and derives from it), and the same declaration in the tester base stage, because its cargo binstall of cargo-nextest can fall back to a source compile.
• contrib/dev-tools/containers/docker-build.sh: passes CARGO_BUILD_JOBS as a build argument when set.
• docs/containers.md: new "Memory and CPU Use" section.
• contrib/dev-tools/experiments/container-build-jobs/: measurement script, raw samples and report.md.
• docs/issues/open/2853-container-build-jobs-limit/: the specification, the manual verification evidence and implementation-retrospective.md (what made this review slow, with proposals for the review process).
• docs/pr-reviews/pr-2854-review/PR-REVIEW.md: the review audit record.

Measured evidence

Release image, uncached, one build at a time on a 32-thread machine:

CARGO_BUILD_JOBS	Wall time	rustc at peak RSS	Peak rustc RSS
4 (default)	836 s	4	10.4 GiB
8	499 s	8	19.8 GiB
16	346 s	17	35.5 GiB

Self-hosted runner (8 vCPU, 16 GB), Build Tracker Image step: 814 s, 842 s and 824 s in three runs of this PR at 4 jobs, against 721 s, 723 s and 749 s in three uncapped develop runs. That is about 13% slower (827 s against 731 s on average). The runs built different commits and the cache state was not checked, so the comparison is rough. container.yaml is unchanged; it can pass a higher value for that runner if wanted. GitHub-hosted runners have 4 vCPUs and are not affected.

Known failing check

Test (Docker) (release) fails on this PR in the step Run Persistence Transition Regression, after the image build passes. The same step fails on develop at this branch's merge base (run 43299605132), so it is not caused by this change.

Out of scope: BuildKit max-parallelism, Docker daemon memory limits and a cap on concurrent builds (machine setup).

What changed in this PR

This PR addresses #2853 by limiting Cargo parallelism during container image builds, reducing memory pressure on many-core machines while allowing explicit overrides.

Changes:

• Defaults Cargo builds in chef-derived stages to four jobs and forwards overrides through the build script.
• Documents memory guidance and measurements for 4, 8, and 16 jobs.
• Adds the measurement script, raw results, issue specification, and verification evidence.

Process: a bug fix with an implementation-plus-spec branch, so fix-bug, create-issue, commit-changes, open-pull-request and write-markdown-docs govern it. The spec has every template section and valid v1 frontmatter; the evidence file misses the records fix-bug asks for (F2, F3).

The change against its claim: the ARG/ENV in chef reaches every compiling stage (all derive from chef; tester, gcc and runtime do not), and docker-build.sh passes the variable only when it is set. The three result rows, the 40%/31% savings, the 1.7x ratio and the 2.2-2.6 GiB per job recompute from the raw samples. Two report statements do not (F4, F5), AC6 is marked DONE with its condition unmet while the description closes the issue (F1), and one spec risk contradicts the Containerfile (F6). A changed value rebuilds the whole image, which the docs omit (F7).

Consistency: links resolve, related artifacts and skill links exist, the ADR paths and the self-hosted runner statement check out, and no word was added to the dictionary.

Hygiene: three Conventional subjects with the [#2853] reference, author equals committer, git diff --check clean, the skill's commit-id check prints nothing, and the closing-keyword scan matches only Closes #2853 in the description. Each commit has one attribution footer line (no rule in the tree on it).

Findings: F1 Major; F2-F7 Minor; F8-F11 Nit.

Checked, no finding: stage derivation; docker-build.sh with and without the variable; the measure.sh watchdog and summary arithmetic; summary files against samples; frontmatter fields against the validator's profile; table shapes and fences.

Process: one new commit, a fast-forward of ca14aeb82 touching Containerfile and measure.sh. It answers the two threads of the earlier automated review; the eleven threads of my last review have no reply, and the head carries no review audit record (F12).

The change against its claim: tester now declares the same ARG/ENV before its cargo binstall, so a source-compile fallback is capped, and the value now also reaches test and test_debug, which derive from tester. The trap in measure.sh is installed once build_pid is set, sends TERM to the build client, waits and exits; the watchdog path is unchanged. Both do what the commit body says. The spec, the description and the chef comment still say that only chef carries the cap (F13).

Prior findings: none of the files behind F1 to F11 changed, so all eleven stand as posted, F1 still Major. F6 changes shape: its bullet now says the test stages are not capped, and at this head they are.

Consistency: no link, path or dictionary change.

Hygiene: Conventional subject with [#2853], body matches the diff, author equals committer, git diff --check clean, the skill's commit-id check prints nothing, and the closing-keyword scan matches only Closes #2853 in the description. Each commit has one attribution footer line (no rule in the tree on it).

Findings: F12 Minor, F13 Minor; F1 to F11 open.

Checked, no finding: trap quoting and timing under set -u; the background build ignoring SIGINT, so the trap is what stops it; the deferred trap during sleep 2; tester stage order; the trial merge.

Process: three commits since my last review, 523914617 (answers to F1 to F11), 03c6c7e9e (wording and the audit record) and 3d9dfebc6 (audit table and reply URLs). The audit record now passes the validator's checks, run offline against this head's review comments: 15 rows, 0 failures.

Prior findings: F1 to F7, F9 to F13 are resolved. AC6 is TODO with M4 tracking the runner check, the description says Related to #2853, and the chef comment, scope bullet and T3 row name both base stages. F8 stays open although its row says FIXED: the 08:50 entry still says the 4-job run started then, and the 10:55 entries sit in a 10:46 commit.

The change against its claim: the F4 fix rewrote the three committed run summaries into the new measure.sh format, and the 16-job drop matches neither the run nor the script (F14). The report states a runner measurement it does not contain (F15). The skill's commit-id check prints four branch ids (F16), and small report wording issues remain (F17).

Process: one new commit, a fast-forward of 3d9dfebc6, answering F14 with a reply and an audit row. The audit record passes the validator's checks, run offline against this head's review comments: 16 rows, 3 log entries, 0 failures. F15 to F20 have no reply yet, and the automated review's R3, R4 and four newer comments are open and not yet in the record.

Prior findings: F14 is resolved. The three run summaries have the same blob ids as when the runs were first committed, and report.md:45 now reads 33.0 GiB, which the samples give (32.964). F1 to F7 and F9 to F13 stay resolved. Still open and non-blocking, with their files unchanged except the moved report lines:

• F8 Nit (progress-log times);
• F15 Minor (report.md:100, the runner run without data);
• F16 Minor (the commit-id check still prints four ids, and PR-REVIEW.md:245-246 add a3aaab735);
• F17 Nit (report wording);
• F19 Minor (audit entries overstate);
• F20 Nit (F6's resolution reference).

The change against its claim: the commit restores the summaries and corrects the one cell, as its message says. Its account of the 32.9 (a baseline rebuilt from the rounded 47.0 GiB) recomputes to 32.93. The new Method sentence says the peak rustc RSS is not in the summary files, but each carries it (F21).

Verdict: no finding here makes the merged bytes wrong, but the record is not complete. Eleven threads are open: F15 to F20 have no reply yet, and the automated review's R3, R4 and four newer comments are neither answered nor in the record. As in earlier rounds, the verdict stays a comment, without ACK, until each open thread has a reply and a row and the validator passes over them.

Hygiene: Conventional subject with [#2853], body matches the diff, author equals committer, git diff --check clean, and the closing-keyword scan finds no match. Each commit has one attribution footer line (no rule in the tree on it).

One thread is open: F21 from my previous review was posted while this commit was being made, and it has no reply and no row yet. The record's audit-local F21 to F24 name the automated comments, so my F21 and this review's F22 and F23 need new audit IDs under the skill's collision rule.

Prior findings: F15, F17 and F20 are resolved, as are R3 and R4 from the automated review. Three rows say FIXED but are not fixed at this head (F22):

• F8: ISSUE.md:124 still says the 4-job run started at 08:50.
• F16: the skill's commit-id check still prints 334decbf9 (PR-REVIEW.md:233) and a3aaab735 (PR-REVIEW.md:258-259).
• F19: the two 11:05 UTC Processing Log entries are unchanged and still sit in a 10:52:06 commit.

F21 stays open: report.md:24-25 still says the peak RSS is not in the summaries, and now contradicts line 61.

The change against its claim: export LC_ALL=C and the PID filter awk '$1 != self' do what the message says. The filter never removes a line in practice, since pgrep -af does not match the script's own command line. The overlap section now scopes "at most two" to the workspace branches and names the tester fallback. The cache paragraph now distinguishes a new key from pruning. The progress log and the report cite commit subjects. One new report sentence overstates (F23).

Hygiene: Conventional subject with [#2853], body matches the diff, author equals committer, git diff --check clean, and the closing-keyword scan finds no match. Each commit has one attribution footer line (no rule in the tree on it).

Prior findings: F21, F23 and F8 are resolved: the Method paragraph now copies the peak RSS from the summaries and recomputes only the count, the overlap paragraph states the no-fallback point as an assumption, and ISSUE.md:124 no longer dates the 4-job run at 08:50. F19 is resolved by the appended correction, the form the skill prescribes. F22 is resolved for F8 and F19. F16 stays open: the skill's commit-id check still prints 334decbf9 and a3aaab735, now from the F26 row's Concern (PR-REVIEW.md:418), which quotes them while that row's verification line says no branch id remains.

The change against its claim: the report, spec and audit edits do what the message says, except for the F16 residue above. The new correction entry is stamped before the replies it reports, and one of its sentences does not parse (F25).

Consistency: the Method, "Per-process memory" and overlap paragraphs now agree with each other and with the restored summaries. Links and paths resolve.

The change against its claim: the message matches the diff. The F12 row now records the reply edits. The F16 row cites the three commits that together removed the ids, and all three subjects exist on this branch. The F26 Concern names no hash.

Hygiene: Conventional subject with [#2853], body matches the diff, author equals committer, git diff --check clean, and the closing-keyword scan finds no match. Each commit has one attribution footer line (no rule in the tree on it).

Verdict: COMMENT, no ACK, until the F25 thread has its row; no finding blocks, and the code and the report are unchanged since the previous review.

Findings: F28 Minor.

Checked, no finding: every Reply URL against its thread; each edited reply's text against the branch subjects; the two 13:17 entries against the capture's timestamps; the description, unchanged.

On the loop's compute node at this head, against the merge base ec1f58ec9 (receipt server-gates-kranich-839): the repository's pre-commit gate and lint roster exit 0 and the tree left clean; the repository's audit validator on pr-2854-review exit 0 (30 rows, 7 log entries, no failures), though it checks only the rows the record has. This push changes only the audit record, so no package tests apply. F28 checked against the bytes at posting: no line of PR-REVIEW.md cites the comment id 4562957889.

Reviewed at 9a69a6c09e7394043d573f34b9fcf771a207aa22. Recomputed from the bytes at this head, against the merge base ec1f58ec9; git merge-tree against develop ec1f58ec9 writes tree bdc11cc1a, identical to the head tree, so the merge is clean.

Process: three commits since my last review: 82d8af309 (runner times and a retrospective), 26012748a (the F28 row) and 9a69a6c09 (the F29 row). All 32 threads have a reply, a row whose Source URL cites the thread, and a resolution. The audit record passes the validator's checks, run offline against this head's review comments: 32 rows, 9 log entries, 0 failures. The skill's commit-id check prints nothing.

Prior findings: F28 is resolved. The F28 row records my earlier F25, and the F29 row records my previous F28, with its review, severity, reply and resolution subject matching the capture. Its 13:32 log entry sits in a 13:32:43 commit, after the 13:32:09 reply it reports.

The change against its claim: the runner figures are internally consistent. The means are 827 s and 731 s, a 96 s (13%) difference, and V4, report.md, the AC6 row and the description agree on them and on their limits. The run ids and times come from the forge and cannot be recomputed offline. M4 and T6 are DONE, and AC6 stays TODO with the decision left to the maintainer. The description links the issue without a closing keyword. The retrospective's tree counts recompute: 61 shipped lines, 1,816 added lines in 14 files, 832 sample lines, a 454-line record, 4/16/11 severities and 8 pushes. Its review counts do not (F30). The spec's pointer to it no longer repeats them.

Hygiene: Conventional subjects with [#2853], bodies match their diffs, author equals committer, git diff --check clean, and the closing-keyword scan finds no match. Each commit has one attribution footer line (no rule in the tree on it).

Verdict: the shipped change is unchanged since the second round, every figure a reader relies on recomputes, and the record is complete for every thread. F30 is wording in the retrospective and does not block.

Findings: F30 Nit.

Checked, no finding: the F1 and F15 verification lines against V4; every Reply URL against its thread; the new links; the Markdown shape of the changed files.

[Nit][F30] The review counts were stale when this file was committed (13:27:29Z).

At 13:26:00Z da2ce7 posted a seventh review and the automated reviewer a fourth, and a 32nd finding followed (answered at 13:32:09Z, recorded as F29). So "nine reviews (six by da2ce7, three by the automated reviewer)", "31 findings, all answered and resolved" (line 38), "The last thread was resolved at 13:21 UTC" (line 40), "the same 31 findings" (line 67) and "all 31 findings" (line 241) describe an earlier moment. State the time the counts were taken, or update them. The tree-derived counts (61, 1,816, 14, 832, 454, 4/16/11, 8 pushes) all recompute.

Agreed: the counts were taken before the two reviews of 13:26:00 UTC and the retrospective was committed at 13:27:29 UTC, so "nine reviews" and "31 findings" were already stale. The maintainer decided to defer this: it will be corrected in the close-out after merge (state the time the counts were taken and the final totals), together with its row in the audit record. No push is made for it now, so the approved head stays as reviewed. Leaving this thread open until that correction lands.

[da2ce7]

ACK 9a69a6c — every review thread has a reply, an audit row and a resolution, the record passes the validator's checks, the commit-id check is empty, the report's figures recompute and the trial merge against develop is clean
