Artifact Description [1e7a8c10ad]

Artifact 1e7a8c10ad58e9784eb011bcc04beb837ad043d54285d340040fae68baf34f86:

• File .fossil-settings/ignore-glob
  • 2026-07-30 14:53:24 — part of check-in [9b95e3b9e5] on branch shun-implementation — ignore the crash-leftover working files: dst workspace and pack temp

    .zit-dst-checkout-ws/ is the process directory the crash-recovery sweeps make their throwaway workspaces under. It is created at run start and removed by a defer at run end, so it is normally invisible -- but a killed or crashed sweep leaves the whole tree, .zit stores and all.

    .zit-pack-tmp is the fixed-name temp pack and shun --force write the new generation into before the atomic rename; a run that dies between create and rename leaves one beside .zit.

    Both are dotfiles, so a bare 'fossil extras' skips them and the tree reads clean while they sit there -- the same blind spot the .agent-config glob closed. Pinned by packaging_test. (user: dmestas, size: 194) [annotate] [blame] [check-ins using]

  • 2026-07-30 18:47:05 — part of check-in [e57bcceadf] on branch trunk — merge shun-implementation: shunning and space reclamation

    A repository-local shun table (sync SS3.3), the zit shun verb over it, and the four suppression directions the drafts require: never requested, never announced or served, an arriving copy discarded, and the bytes reclaimed on demand through the existing atomic rewrite.

    Built as eight slices, each through design review, TDD, spec audit, three review lenses, mutation proof and a full gate. Reading the eight as one change afterwards found what none of them could alone: a peer-reachable assert that crashed the client on a malformed DELTASRC, and a pre-rename guard that re-stat'ed a stale handle so two concurrent rewrites could un-shun each other.

    Two defects predating the feature are fixed on the way. FileStorage.sizeImpl answers from a cached watermark, so pack's tail-revalidate compared a key against the number it was derived from and could never abort -- the guard had never worked. And a malformed file card could trap the client through PendingDeltaQueue.

    Format version stays 1: an older binary meets an unknown frame kind and rejects cleanly, which is what it should do with a tombstone it cannot read. No interchange surface changed -- smoke covers ten fossil 2.28 scenarios including a fossil clone of a defer-shunned store and a real fossil push of a shunned artifact.

    Known and recorded, not blocking: a running zit serve keeps serving the old inode until restarted after a --force reclaim swaps generations. (user: dmestas, size: 194) [annotate] [blame] [check-ins using]

  • 2026-07-31 04:56:22 — part of check-in [562cf5be74] on branch sub-manifest — merge trunk: shun, the release-assert guard, and the split test lanes

    Trunk since d186a44e brought the repository shun table and its whole- branch verification fixes, the release-assert guard, the `test`/`gate` lane split, the structurally bounded logstore priority window, and the vendored crc32. Eight files conflicted. The decisions worth naming:

    Lanes. `git-import-e2e` was a compile-only proof hanging off `test`; that is exactly the cost trunk moved to `gate`, so it moves with `e2e` and `smoke`. `import-git-bench` stays on `test` because it registers a real unit-test run rather than a compile proof. `declared_steps` is the union plus `gate`.

    Sync ingest. Both sides rewrote it: trunk added the §7.7 receive-side shun admission, this branch added §7.1 phantom minting for a pushed tree's missing sub-manifests. They compose in one direction — admission is asked first, so a card §7.7 refuses is never stored and mints no phantoms either. The S references of an artifact this repository declines to hold are not names it should then go begging for.

    Client construction. Trunk factored the three verbs' `Client` literal into `syncClient` and threaded `RepoAdmission`; this branch had widened `project_code` into `RepoSyncIdentity`. The helper now carries both, which is what trunk's own comment asked for: three copies of that literal is how a repository filter comes to be wired into two verbs and not the third.

    Per-round server refresh. Trunk made the snapshot mandatory — `error.ServerStorage` rather than serving with no shun table — where this branch read its four sub-manifest fields through fail-open defaults. Trunk's reading wins for all six fields: serving a stale default is the failure, not the fallback.

    Two guards trunk owns caught real defects in this branch's code, which is the whole point of them:

    The total switch in `shunConsequence` refused to compile against the `submanifest` artifact type, exactly as its comment promised. It has an arm now.

    The release-assert guard found nine asserts on untrusted input across six functions. Two were reachable faults, not style: `lookupTree` asserted §4.4 on a sub-manifest a peer supplies, so a malformed node panicked a ReleaseSafe reader and was walked anyway under `--release=fast`. It returns `SubUnresolvable` now, which §5.2 already defines as "absent, or is not a SUBMANIFEST". The empty-S-run assert became an early `null`. The two sub-manifest writers refuse an empty group through a new `SubmanifestWriteError` rather than asserting; the builder's internal path keeps its allocation-only surface through `serializeLeafCore`, since the partitioner is what establishes non- emptiness there. The rest were tautologies or restatements of invariants the card parser already enforces, and now say so in a comment instead of carrying a panic.

    Verified on the merged tree: `gate`, `e2e`, `dst` (6 seeds x 1000 steps), `smoke` (S1-S10, including trunk's new shun interop), and `git- import-e2e` all green, `zig fmt --check` clean. Beyond the suite, the importer was run for real: the empty-email repro imports and its check- in carries `U mohye77`, and marktext imports end to end with the analyzed pin at k=5.
