build_utils: key the caches on the tree, not just the arguments

2026-08-21T16:14:25Z

The eight lru_cache layers take repo-RELATIVE paths - 'hw/bsp/', 'examples//skip.txt', the literal 'hw/bsp' glob - while ci_select._in_repo() chdirs around every call so one process can classify more than one tree. With no cwd in the key the second tree gets the first tree's answers. Reproduced: skip_example('host/bare_api','metro_m0_express') is False at the repo root and STILL False after chdir into a tree where that board does not exist; only cache_clear() gave the right answer. It bites the code-size skill's base-vs-branch worktree compare, /pre-pr, and the first test that points classify_build at a fixture tree. Master had no caching here, so the hazard arrived with it. _cwd_cache puts os.getcwd() in the key. The 199-test suite passed before only because every test happens to pass the real REPO; the new TestCachesAreKeyedOnTheTree crosses trees deliberately. Also adds the drift guard the class rule was missing. Ports, hw/mcu, get_deps tokens and bsp families each have one; the class rule had only a comment claiming vendor_host.c was the sole "enabled by no example config" case until its removal - which src/class/bth falsifies today. TestClassesWithNoEnablingExample pins the set to {bth}, so a class added before its first example, or an example config flipped to 0, fails here instead of silently selecting nothing on both axes. Verified it fires by adding a class dir nothing enables.

ci: fix nine ways the selection under-selected or mismatched

2026-08-21T05:41:47Z

Every one of these dropped coverage silently - the worst failure mode here, because the PR still goes green. Found by review, each reproduced first. Selection rules: * class_macros derived the config macro from the class DIRECTORY, so a change to src/class/midi/midi2_device.c selected the midi_test examples (which do not compile it) and never examples/device/midi2_device (the only one that enables CFG_TUD_MIDI2, and the only one that does). The file's own macro is unioned in where it differs - union, never replace: over-selecting costs a build, under-selecting merges a break. * the ${FAMILY_MCUS} fallback added for espressif fired on any family whose _family_mcus came back empty, and _cmake_sets is if()-blind and keeps the FIRST definition - so mcx/frdm_mcxn947 answered MCXA15, a token six examples' skip.txt names, dropping 12 firmware images CMake builds. Limited now to families that never spell set(FAMILY_MCUS ...) at all. * lib_examples read only an example's top-level CMakeLists.txt/Makefile; host/msc_file_explorer_freertos names lib/embedded-cli in src/CMakeLists.txt and survived by luck. The whole example tree is scanned. (SEGGER_RTT and rt-thread still resolve to nothing: all three references sit inside a LOGGER=rtt guard no CI build sets - the documented ruling, not a miss.) * get_family_boards applied ci_skip_boards/ci_preferred_boards only under GITHUB_ACTIONS/CIRCLECI, so the selector answered differently on a laptop than on a runner; _prune_buildable forces CI semantics. Its one-board pick also abandoned the whole preferred list when entry one could not build the -e set, and asked skip_example without the build's -D tokens. * _config_enables and lib_examples still read with the locale encoding - under LC_ALL=C the selector tracebacked on three tracked tusb_config.h files. The whole selector and its suite run clean there now. Workflows: * the Membrowse Upload step omitted $EX_ARGS, but --one-first now picks the board from the -e set, so it configured a different, empty build dir and uploaded --identical for a board never compiled. It takes $EX_ARGS for the BOARD; the target stays the aggregate, which has no DEPENDS and still records every example. * blanking FAM_REGEX reset only build_filtered, leaving the build scoped while code-metrics took the UNSCOPED branch and diffed a 1-family run against the full averaged baseline. All three drop together now, as CircleCI's fall-open does. * CircleCI's EX_ARGS had no character screen and is used unquoted, and its code-metrics job still exit 1'd on an empty metrics set - which a scoped build makes a legitimate outcome. * a `ci-full` PR label now turns the scoping off for one PR. A selector bug under-selects silently, and without a label the only ways back to a full matrix are accidental. Performance, since the selector gates every other job: family.cmake texts are read once rather than per changed directory (a 6,000-file dep bump re-read 84 files 99,892 times) and _scrape_mcu is cached: 2.2s -> 0.29s there, 0.8s -> 0.33s on a class diff. Tests: a drift guard for hw/bsp families absent from ci_set_matrix.family_list (they select zero legs now, where they used to ride the full matrix); the rule-4 port test asserted a SUBSET, which set() satisfies, so it could not fail on the empty selection it exists to catch; the GITHUB_ENV guard test counted a SUM of two guards. Drops metrics.py's --only-examples, which nothing called, and applies the TOTAL scrub to the by-example branch that skipped it.

ci: scope the build matrix and the HIL run to what a PR affects

2026-08-21T04:07:27Z

Every PR built all 74 legs (2494 example builds on GHA cmake alone) and flashed all 30 rig boards, whatever it touched. One classifier now walks the PR diff twice and answers three questions: which families to build, which examples per family, and which boards run which tests. Fail-open throughout - anything no rule classifies, any exception, any unusable output falls back to the full matrix, and a master push always builds everything. test/hil/helper/hil_select.py moves to tools/ci_select.py: it is no longer HIL-only, and tools/ is where the build side can import it. test_hil_select.py follows it as test_ci_select.py. Rules (docs/superpowers/specs/2026-08-19-ci-build-family-filter-design.md holds the full table): a port selects the families whose family.cmake references it, and its role - a dcd change skips host examples and vice versa; a class selects only the examples whose tusb_config.h enables its CFG_TU[DH]_ macro, following cross-class includes; an example selects itself; hw/bsp selects its family or board; hw/mcu and lib select whoever references them. CMake is the reference for all of it - make follows whatever cmake decides, family.mk is never scanned. Empty means empty (maintainer ruling): a rule that classifies a path to nothing selects nothing. Ports no family references, classes no config enables, libs no example builds and hw/mcu paths that resolve nowhere are all real - nothing compiles them, so nothing can validate them, and the master-push build is the net. Structural tests pin each such case with an explicit allowlist, so the day one stops being empty it fails pre-commit instead of silently narrowing CI. Per-example builds: build.py grows a repeatable -e, resolved against the targets CMake actually registered and batched into one `cmake --build --target a b c`. build_utils mirrors CMake's family_filter (the whole FAMILY_MCUS list, ${...} and string(TOUPPER ...) resolved) for the cmake side, while the make side keeps master's algorithm verbatim - the two build systems answer differently and a shared answer breaks lpc54's make link. hil-build gains this even on a full selection: 1702 example builds become 515. Transport: the selection travels as a file, never an argv or env var - a mass-sweep diff selects 261 KB against a 128 KiB exec limit, and E2BIG would fail the step before its own fallback could run. CircleCI carries the example map inside the generated config (pipeline parameters cap at 512 chars), swapped into the parameter defaults by sentinel match, and drops the scoping wholesale if that rewrite fails. Every PR-derived value written to $GITHUB_ENV/$GITHUB_OUTPUT is character-screened. Code metrics follow the scoping: metrics.py emits per-example totals, and metrics_pair_compare compares the (board, example) pairs present on both sides instead of a scoped run against a full-matrix average. The selector's own suite gates it in both providers: a selector that exits 0 with valid-but-wrong JSON is the one failure fail-open cannot catch, so a red suite means the full matrix.
