fix(orchestrator): conformance-campaign server and runtime fixes - #151
Conversation
📝 WalkthroughWalkthroughThe PR expands conformance targets and submission payloads. It adds Docker retry handling, Rosetta preparation, improved golden downloads, configuration-aware runner paths, explicit runner completion results, privilege setup changes, and periodic SQLite WAL checkpointing. ChangesRuntime and conformance updates
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR changes runner provisioning, Docker recovery, Rosetta runtime setup, and SQLite persistence. At the current head, x86_64 jobs can still start without required libraries, Docker recovery can reset a live data root, restored work can remain blocked, and committed writes can surface as failures while the store is held. These are concrete correctness and availability risks that should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Blocking performance concern in That trades an occasional oversized-WAL checkpoint for a checkpoint/fsync on every runner event. I reproduced the mechanism locally with SQLite WAL + That is ~35x slower before Preloop's JSON serialization, encryption, projection rewrites, or concurrent runner traffic. There is also an observability issue: Suggested direction:
SQLite docs: https://sqlite.org/pragma.html#pragma_wal_checkpoint and https://sqlite.org/wal.html. Also note the three unresolved inline threads already present on this PR: |

A blocked PRAGMA wal_checkpoint(TRUNCATE) can hold the sole store connection for roughly 50 seconds, so every checkpoint interval can freeze other store operations. Each of the ten retries independently honors the 5-second busy_timeout; the 10 ms sleep does not bound the total wait.

maybe_checkpoint_wal returns an error after the transaction has already committed, so each affected store_* method reports persistence failure for a write that succeeded. A retry can then hit constraint failures or duplicate non-idempotent inserts such as log chunks and control events.

Make post-commit WAL checkpoint failures non-fatal.
tx.commit() makes the write durable before maybe_checkpoint_wal runs. A blocked checkpoint can therefore return an error for a successful write. PRAGMA busy_timeout = 5000 can make each of ten retries wait about five seconds while holding the shared connection mutex, blocking store operations for about 50 seconds. Defer checkpoint maintenance, use a short-timeout or separate path, and report failures through warnings and metrics.

…ments Follow-ups to the conformance campaign fixes (PR #151): - docker: the krunfw guest kernel has fuse built in, but /dev boots as a plain tmpfs with no device nodes, so fuse-overlayfs (dockerd's fallback when its overlay probe fails) dies with 'fuse: device not found'. The hook now creates /dev/fuse when the kernel lists fuse, letting dockerd auto-pick fuse-overlayfs (CoW) — on this kernel dockerd's overlay2 probe mount gets EINVAL and overlay2 is never viable, so the earlier fix was falling back to vfs. vfs is now forced only when overlay fails AND fuse is absent. - RLIMIT_NOFILE: 524288 instead of 1048576 — systemd's built-in hard default, which is what GitHub's runner service inherits (exact parity). - guest PATH: cargo bin dir matches the runner user (/home/<user>/.cargo) instead of hardcoded /root/.cargo/bin, which the unprivileged runner cannot stat (nodejs/ci EACCES). - multiarch shim: add libsystemd0:amd64 (valkey's x86_64 tarballs link libsystemd.so.0). Verified live on the golden VM: hook creates /dev/fuse, dockerd 28.0.4 reports Storage Driver: fuse-overlayfs, and hello-world runs. 61 orchestrator tests pass.
Fixes found running the 13-target real-world conformance campaign on the
official runner-large golden (Apple Silicon, arm64).
Server fixes:
- docker: probe overlay and force overlay2/vfs storage driver in
daemon.json; fuse-overlayfs cannot mount in the smolvm kernel and killed
every container job (wheel builds now run).
- pool: runner completion via oneshot instead of re-polling a completed
&mut JoinHandle (tokio 'JoinHandle polled after completion' panic that
tore the pool down at machine ~60).
- store: PRAGMA wal_checkpoint(TRUNCATE) after each commit; the per-event
run rewrite grew the WAL to 429MB and froze the server.
- rosetta: prepare_rosetta_multiarch() installs amd64 loader+libc
(libc6/libgcc-s1/libstdc++6/zlib1g/libsystemd0:amd64) into the packed
golden during the prep boot on Apple Silicon, so dynamically linked
x86_64 binaries run under Rosetta (react optipng-bin, valkey x86_64
tarballs). Fingerprint gains rosetta_libs to re-prep stale bases; the
arm64 apt sources are scoped (Architectures: arm64) with an
archive.ubuntu.com [arch=amd64] source across all four suites.
- runner_user wrapper: raise RLIMIT_NOFILE to 524288 (GitHub's systemd
default) as root before the setpriv drop; --init-groups now correct in
both branches via sudo. Fixes valkey's 'maximum open files' EPERM.
- guest PATH: cargo bin dir now matches the runner user instead of
hardcoding /root/.cargo/bin, which the unprivileged runner cannot stat
(nodejs/ci EACCES on git lookup).
Harness (conformance-5repos.sh):
- pass --repository {owner}/{repo} on submit (checkouts with explicit refs
synced the client default local/preloop)
- sample the changed-file payload to 50 files (run creation was
O(payload x jobs); deno's 8500-file list timed out)
- PR-event retry carries an action; fingerprint replication matches the
rosetta_libs field
Addresses the blocking review concern: PRAGMA wal_checkpoint(TRUNCATE) after every store_inner/store_run_event commit fsyncs the DB per runner event (~11-35x slower in a WAL micro-benchmark, head-of-line blocking on the single connection). Now a truncating checkpoint runs only every 128 commits (WAL_CHECKPOINT_INTERVAL); SQLite's background wal_autocheckpoint bounds routine growth between truncations. The checkpoint_wal helper (result-row read + busy retry) is retained for observability. Bench (1500 small WAL txns, synchronous=NORMAL): truncate every commit: 0.107 ms/commit periodic (every 128): 0.0095 ms/commit, WAL bounded ~366 KB 21 store tests pass.
Completes the dockerd-restart hardening: after resetting the data root, the second start_dockerd attempt no longer swallows failure with exit 0. It now exits 1 so the provision path logs the failed startup (the caller already treats docker start as non-fatal — only container jobs depend on it — so non-container jobs still proceed, but the failure is visible).

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Rosetta install failures are silently swallowed on the non-root path.
run_as_root_or_sudo builds two branches. The sudo branch ends with || true, so any failure of dpkg --add-architecture, apt-get update, apt-get install, or the final test -f /lib64/ld-linux-x86-64.so.2 returns exit code 0. The check at Line 1972 then never fires, and the golden is recorded as prepared without the amd64 loader. The official golden declares USER runner, so machine exec lands on a non-root user and this is the branch that runs.
Do not use run_as_root_or_sudo here. Propagate the guest exit code instead.

The equal-version branch byte-compared the installed binary against the release asset and reinstalled on any drift. That clobbered a source build from newer main: main reports the same version string as the latest tag (no bump between tag and HEAD), so a build carrying #149/#151/#164 was treated as drift and replaced with the stale release binary every hour. Embed the build commit (build.rs reads git rev-parse HEAD) and expose it in 'preloop version'. The updater now compares commits via the GitHub compare API when versions are equal: - release commit is ahead of installed (installed is an ancestor — the v0.30.2 deaf-runner case) -> reinstall - installed is at or beyond the release -> keep - diverged history (release cut from a dist commit off main, or a local build) or unverifiable (no embedded commit) -> keep; never clobber a real build on an ambiguous comparison Keeps the version-greater upgrade path and the version-less stop unchanged. Drops the byte-compare and its tests; adds decision-mapping tests for ahead/behind/identical/diverged/unknown.
