ci: compile fbuild once, path-selected board dispatch (badges stay current), main-only cache saves - #1574
Merged
Conversation
Every board job (~76 in the nightly sweep) recompiled the same board-independent fbuild-cli + fbuild-daemon debug build: 26,406s of runner time per sweep, ~350s of each ~550s job. A single fbuild_bin job now builds it and uploads an artifact; template_build.yml downloads it via the new fbuild-artifact input and skips soldr/apt/compile. Direct build-<board>.yml dispatches keep the standalone compile path. Follows zackees/ci.yml policy-rust: compile once, runners only execute.
A single non-main board sweep saved 151 entries (~79 x ~1GB toolchain caches), pushing the repo to 35.8GB and evicting main's setup-soldr Rust build cache: the shared fbuild compile ran at 0/621 zccache hits (383s). Branches and PRs now restore main's entries but never save, per zackees/ci.yml CACHE-003.

…ay current Since 9f4cc4d removed per-board path triggers, build-<board>.yml only ran when called from a matrix, which never updates that file's badge: every board badge was frozen (last runs 2026-09-15..21). nightly-platforms.yml is now a dispatcher. On push to main it selects boards whose trigger paths changed (ci/select_boards.py, reusing render_paths_for_board); on its schedule it selects every board. It compiles fbuild once and gh-workflow-runs each board workflow with its run id, so each board is its own run (badge moves) yet downloads the shared binary. Replaying the last 60 main pushes: 380 board runs vs 4,800 for all boards on every push (7%).

Added path-selected board dispatch so README badges stay current. On push to main, End-to-end test (run 36519172952): 80/80 dispatched, 79 passed. ESP32 Dev fails with the known include-farm error, which predates this PR. The full sweep used 5,035 s of runner time vs 33,338 s before. Replaying 60 pushes to main gives 380 board runs vs 4,800 (7%). Proposed as fleet policy in zackees/ci.yml#69. |
Measured on 50 boards: builds without the cache took 1738s total vs 2248s with the cache (restore + save + builds); a cold download is faster than the cache round-trip. Only silabs (MGM240: 569s cold, a ~480MB silabs-core download at a few MB/s) opts in, recorded in board_families.json. This also stops main from saving ~79 x ~1GB entries per sweep, which would evict the setup-soldr Rust build cache the shared fbuild compile depends on. The cross-board restore fallback is dropped: another board's cache is mostly the wrong toolchain.

Iteration 3: the per-board toolchain cache is now opt-in per family ( |
The ubuntu PR gate's Test step spent ~130s of test time on three things: - fbuild-packages-fetch retry tests used production backoffs (1+2+4+8s) serialized behind network_test_guard; they now use the existing FAST_RETRY_TIMING via a new get_with_retry_timed. - lock_recovers_stale_lock_dir planted an owner-less lock and waited out the real 30s MISSING_OWNER_GRACE; it now plants a dead-PID owner, which the acquire loop reclaims immediately. - resolve_rejects_corrupt_cache_entry refetched from an unresolvable host, which is retried with production backoff (15s); a local 404 fails the refetch immediately. Coverage of each contract is unchanged, and the production backoff constants stay asserted. Local: fbuild-packages-fetch lib tests 102.4s -> 1.7s, fbuild-toolchain 15.4s -> 0.2s.

- Around line 627-632: Update the workflow dispatch loop in the generated `run:`
script so a failed `gh workflow run` for one workflow does not stop later
iterations. Record dispatch failures, continue dispatching every workflow, and
exit nonzero after the loop if any dispatch failed; keep the success message
limited to successful dispatches.
- Around line 219-221: Update the `actions/checkout@v6` configuration for the
shared `fbuild_bin` checkout to set `persist-credentials` to false, alongside
the existing `ref` setting.
Review comments at @crates/fbuild-toolchain/src/lnk/resolver.rs:
- Around line 308-324: Update the test using serve_one_404 so it signals when
the listener accepts a connection, and assert that signal with recv_timeout
alongside the expected refetch error. Bound the listener’s I/O so the test can
safely join its thread without blocking indefinitely.

…to one binary each 26 top-level tests/*.rs files each linked the crate's full dependency graph as a separate binary. They are now modules of tests/it/main.rs (zackees/ci.yml RUST-005). avr_build and eh_frame_strip_esp32 stay standalone: their #[ignore]d download tests mutate process env vars that other ignored tests read, so sharing a process could race. Local: cargo test --no-run -p fbuild-build -p fbuild-daemon after a clean of those crates went 59-79s -> 20-31s. Test counts unchanged.
- Dylint ban_std_pathbuf allowlist, docs and run instructions pointed at the old tests/*.rs paths (Dylint policy failed on the stale entries). - acceptance-205.yml and esp32s3-size-parity.yml selected tests with --test <file>; they now run --test it with a module-qualified filter. All four acceptance filters verified against --list. - Dispatcher: a failed gh workflow run no longer stops later boards; failures are collected and fail the job once at the end. - fbuild_bin checkout sets persist-credentials: false. - resolve_rejects_corrupt_cache_entry now asserts the refetch actually reached the local server, with bounded accept/socket I/O and a join.
clippy --workspace --all-targets type-checks the same targets, so the preceding cargo check only repeated work. Measured locally with fresh target dirs and warm zccache: check+clippy 194.5s vs clippy alone 106.4s (-45%). Applies to the Ubuntu and Windows gates.
Every workspace crate is publish = false and none declares [package.metadata.docs.rs], so no rendered docs are published and the Documentation job (median ~5m22s on every PR push and main merge) built HTML nobody consumed. Doctests still run in cargo test --workspace. See zackees/ci.yml#116.
…ot restored setup-soldr's restored cargo-registry sources lack dylint_internal's template.tar, so any change under dylints/ (lint libraries rebuild on a dylint-cache miss) failed with 'couldn't read template.tar'. Delete the incomplete extraction so cargo re-unpacks it from the .crate.

rust-toolchain.toml pins 1.95.0 and Cargo.toml rust-version is 1.95.0 (check_rust_toolchain_pins.py enforces the equality), so msrv.yml's cargo check --workspace on 1.95.0 repeated what every lane already compiles, and the Linux gate's clippy --all-targets covers more. Saved ~5m37s of runner time per PR push.
ban_std_mpsc_in_async_reachable (Dylint) rejects std mpsc. The server thread now returns whether it accepted a request, and the test asserts that from the (already bounded) join.

A new generated
fbuild_binjob (in ci-full / ci-test / nightly-platforms) buildsfbuild-cli+fbuild-daemononce and uploads it.template_build.ymlgets an optionalfbuild-artifactinput; when set, board jobs download it and skip setup-soldr, apt, and the Rust compile. Directbuild-<board>.ymldispatches keep the standalone compile path.Measured with the nightly sweep (76 boards):
2. Cache saves from main only
That one branch sweep saved 151 cache entries (~79 × ~1 GB per-board toolchain caches), which pushed the repo to 35.8 GB and evicted every entry older than 25 min, including main's setup-soldr Rust build cache. The shared compile ran at 0/621 zccache hits (383 s). Now
setup-soldrsave-cacheand the toolchain/buildactions/cache/savesteps run only onrefs/heads/main, and other refs restore from main. The wall-time gain depends on a warm main cache, so I'll measure it after this merges.Unrelated failure seen
ESP32 Devfailed in the sweep withesp_bt.h:16:10: fatal error: ../../../controller/esp32/esp_bredr_cfg.h: No such file or directory. That comes from the include-farm, not from CI. My guess is it's related to #1567, since the last main nightly before that merge passed.Summary by CodeRabbit
