v0.1.10

Changed

• Documentation site moves from bmoczulski.github.io/yocache to
  yocache.dev. Old GitHub Pages URLs redirect
  automatically.

Added

• YOCACHE_BLOCK_RECIPES now propagates downstream: a recipe that
  transitively DEPENDS on a blocked recipe is skipped too, using
  BB_TASKDEPDATA (bitbake's own recursive per-task dependency closure) to
  find it — no separate graph walk needed. A blocked recipe's own build
  output can be non-deterministic in ways its taskhash never reflects, so a
  downstream consumer's sstate can silently inherit that same problem even
  though its own taskhash looks stable across machines. Both the directly
  blocked recipe and any downstream recipe skipped because of it now log a
  bb.warn (previously bb.note for the direct case) naming the
  responsible upstream recipe(s).

Full Changelog: v0.1.9...v0.1.10

v0.1.9

Removed

• yocache.bbclass no longer POSTs a per-event build report to the server,
  nor logs it locally — the server never persisted any of it (every payload
  was decoded and discarded), so it was pure overhead: hundreds to thousands
  of synchronous requests per build for no benefit. INHERIT += "toaster" and
  INHERIT += "buildhistory" are also dropped from the recommended setup,
  since their only purpose here was unlocking two of the now-removed events
  (MissedSstate, TaskArtifacts). Removed variables: YOCACHE_SKIP_POST,
  YOCACHE_REPORT_ENDPOINT, YOCACHE_LOG, YOCACHE_LOG_LIMIT,
  YOCACHE_EVENTS, YOCACHE_METADATA_TYPES. The server's
  POST /api/build-report endpoint stays, unused, for a possible future
  reinstatement with a real consumer. Mirror wiring and artifact upload are
  unaffected.
• YOCACHE_SKIP_UPLOAD, the blanket dry-run flag, is gone — it was fully
  redundant with YOCACHE_SKIP_UPLOAD_TYPES = "all", which already produces
  the same "log what would be uploaded, send nothing" behavior.

Added

• Hash-equivalence now dedups across different taskhashes that produce the
  same task output (cross-output equivalence): a report whose outhash
  matches an earlier taskhash's outhash unifies onto that taskhash's unihash,
  mirroring bitbake's own hashserv (get_equivalent_for_outhash). Previously
  every taskhash got its own unihash even when two machines' inputs differed
  but their actual output matched, missing sstate reuse bitbake's reference
  server would have found.
• LRU eviction now evicts an sstate task's archive together with its
  .siginfo/.sig sidecars as one unit, ordered by whichever sibling was
  most recently accessed — a cold sidecar can no longer get evicted alone
  and strand (or orphan) its still-cached archive. Once a group is fully
  evicted, its hash-equivalence entries are deleted too, so a unihash never
  outlives the blob it points at.

Full Changelog: v0.1.8...v0.1.9

v0.1.8

Added

• Multi-arch (linux/amd64, linux/arm64) Docker image, built and pushed on
  every release to GHCR (ghcr.io/bmoczulski/yocache) and Docker Hub
  (docker.io/moczulski/yocache). Runs as a non-root user by default, self-heals
  bind-mount ownership on the data volume when started as root, and honors an
  explicit --user uid:gid override.

Full Changelog: v0.1.7...v0.1.8

v0.1.7

Added

• Project website under site/ (Astro + Starlight): landing page plus
  user-facing docs — getting started, why YoCache, server & client
  configuration, FAQ. Published to GitHub Pages on every push to main that
  touches site/, independent of versioned releases.
• Every server flag can now be set via a YOCACHE_<FLAG> environment
  variable (e.g. YOCACHE_DATA_DIR, YOCACHE_ADDR), with CLI flags still
  taking precedence over env vars over compiled-in defaults — the config
  path Docker and systemd deployments expect.
• --hashequiv-addr (default :6767, on by default) opens a second,
  dedicated raw-TCP listener speaking bitbake's legacy OEHASHEQUIV wire
  protocol directly (no WebSocket), for pre-Scarthgap bitbake (Dunfell and
  earlier) whose hash-equivalence client can't speak ws://. Point
  BB_HASHSERVE at host:6767 to use it instead of
  ws://host:6768/hashequiv; pass --hashequiv-addr "" to disable it.
• GET /api/stats (and the startup "cache inventory" log line) now report
  hash-equivalence store size: hashequiv_taskhashes (recorded
  taskhash->unihash mappings), hashequiv_unihashes (distinct unihashes,
  the dedup signal), and hashequiv_outhashes (recorded outhash records).
• meta-yocache now declares every Yocto release from dunfell through
  wrynose in LAYERSERIES_COMPAT_yocache, closing the gap between the
  previously-declared dunfell/kirkstone/wrynose.

Changed

• Breaking: the five path flags (--db, --downloads, --sstate,
  --ledger, --access-log) are replaced by a single --data-dir (default
  var, same on-disk layout underneath: yocache.db, downloads/, sstate/,
  yocache.ledger.jsonl, yocache.access.jsonl). Anything passing the old
  flags needs to switch to --data-dir pointing at one root — this also
  clears the way for a single Docker volume mount instead of five.

Full Changelog: v0.1.6...v0.1.7

v0.1.6

Fixed

• sstate build-time attribution now credits upstream, non-sstate-cacheable
  tasks (do_fetch/do_unpack/do_patch/do_configure/do_compile/
  do_install) to whichever downstream sstate object also lets bitbake skip
  them, instead of only reporting that object's own (typically sub-second)
  packaging time. Previously a compile-heavy recipe's reported "time saved"
  could be off by orders of magnitude, since do_compile itself is never a
  cache-eligible task in a typical build.

Full Changelog: v0.1.5...v0.1.6

v0.1.5

Added

• meta-yocache now declares kirkstone in LAYERSERIES_COMPAT_yocache.

Full Changelog: v0.1.4...v0.1.5

v0.1.4

Fixed

• Build-end cache-benefit summary line no longer pads in a misleading
  "0 download object(s)" / "saving ~00:00:00" clause for a side (reused or
  contributed) the build never actually touched.

Full Changelog: v0.1.3...v0.1.4

v0.1.3

Added

• GET /api/stats — JSON cache inventory summary (file counts, deduplicated
  sstate recipe count, cumulative size per category), computed live from the
  inventory DB so it can be polled at will instead of only at startup.
• GET /api/build-stats/{buildname} — per-build cache-benefit summary: bytes
  uploaded/downloaded and, for sstate, the build time contributed and saved
  by reusing cache instead of rebuilding. yocache.bbclass now captures each
  sstate task's wall-clock build time and uploads it alongside the artifact,
  and prints a one-line "yocache helped you / you helped your teammates"
  summary at the end of every build.
• --build-stats-ttl (default 720h, ~1 month) controls how long per-build
  download stats are retained before an in-process daily garbage collection
  sweep prunes them.

Full Changelog: v0.1.2...v0.1.3

v0.1.2

Fixed

• Release workflow now actually publishes the curated CHANGELOG.md section
  as GitHub Release notes. changelog.disable: true in .goreleaser.yaml was
  skipping the whole changelog/release-notes pipe, so --release-notes was
  silently ignored and v0.1.1 shipped with an empty release body.
