-R: say which mistake was made, not 'no checkout here' (#97)

The discovery message tells the operator to name the repository with -R. For a -R failure that advises supplying the flag already supplied, and it reads the same whether the path was mistyped or simply holds no repository -- so a stale path in a script looked like a bug in the verb. Reported against tarball; every -R verb had it. One reporter, routed through all nine resolveRoot call sites; the no-flag discovery message is unchanged. check-in: 10a1236a7a user: dmestas tags: trunk

archive differential: unpack zips without an unzip binary (#95)

The runners have no unzip, so the harness exited 2 for a missing tool and the step failed on its own coverage guard instead. Adding a third tool to the battery for one step is the worse trade: python3 is already required here, and ZipFile.extractall drops modes and symlinks -- the exact defect this differential exists to catch -- so the external attributes are applied explicitly rather than trusted to an extractor. check-in: 2420f6fb88 user: dmestas tags: trunk

19:16
ci: the archive differential asserts on output it never captured

archive-fossil-diff.sh writes the per-format comparison to stderr, but the step piped only stdout into diff.log, so the 'kinds compared' line the coverage guard greps for was never in the file -- it counted 0 on every platform and the step could not pass.

pipefail with it: the pipeline was taking tee's status, so the differential's own failure, including its exit 2 for a missing tool, was swallowed and only the guard could ever fail this step. check-in: 98243aad6a user: dmestas tags: trunk

zit purge: recoverable removal of leaf check-ins (#87)

Removes a check-in and the blobs only it introduced, into a local graveyard that purge undo restores and purge obliterate empties.

The drop set is (seed + reachable(seed)) minus reachable(everything retained), so a blob a surviving check-in still names is never freed -- dropping it would create a phantom rather than reclaim anything. Only leaves go, judged over the whole named set: purging a parent alongside its child is accepted, purging it alone is refused.

Reuses shun's rewriteAndSwap and records no tombstone: a purge is local, so content that already synced comes back from a peer. The help says so and points at shun. check-in: 8536f59fba user: dmestas tags: trunk

18:41
ls: size from the frame header, full names through the index (#96)

A blob's plaintext length is already in every frame kind -- a zlib container states it outright, a delta carries it in its own header -- so --size reports one without resolving a chain. The binary verdict cannot be had that way (a NUL may be the last byte), so --long still reads every blob and keeps its exact columns.

The larger cost was neither: resolveHexPrefix scanned the whole store per file to resolve a full-width name the digest index answers outright, which slowed plain ls too. On tcl's tip --long drops 167s to 93s and --size costs what plain ls costs. check-in: 3b7e8c7569 user: dmestas tags: trunk

17:10
smoke S11: a stock fossil push refused by the content policy (#88)

Unlike S10, which its own comment notes survives deleting the server's admission check, this one genuinely exercises the decision: the violating file is ordinary new content fossil pushes because it is new.

Records the limitation in the header: fossil exits 0 after printing the refusal, so the assertions are on the store and on fossil's output rather than its exit status. zit push exits 1. check-in: abc41cae82 user: dmestas tags: trunk

16:41
serve refuses a push that violates its content policy (#88)

#81's predicates bind a checkout; nothing stopped a push from a clone that never adopted them, or from stock fossil. Fossil cannot close this at all -- its hooks are before-commit (client-side) and after-receive.

The policy is the SERVER's, resolved per round from its own settings, never from the artifacts arriving: a push carrying its own policy would otherwise arrive bearing permission to land. Only inspecting rules cross the wire; before-commit has no server-side counterpart.

A push sends artifacts by hash and only a manifest names paths, so the walk is manifest-first -- the policy gates what becomes REACHABLE, not what bytes transit. Decided before ingest, so a refusal stores nothing, and the whole round is refused rather than half of it.

Verified against fossil 2.28: it prints the refusal text verbatim and lands nothing. Note it exits 0 while doing so, where zit push exits 1. closed check-in: e091f2ac80 user: dmestas tags: push-policy

16:41
grep: search a file's history for a literal (#92)

zit had no content search at all -- not git's pickaxe, not fossil grep's file-scoped walk. This is the latter: each named file's stored versions newest-first, every version whose content contains PATTERN reported with line numbers. A run of check-ins that never touched the file shares one blob and reports once.

PATTERN is literal; zit carries no regex engine and git log -S is literal for the same reason. Working-tree search stays ripgrep's job -- what only zit can do is read content that is not on disk.

A version the store cannot produce is counted and reported on stderr, not skipped: a search that quietly examined less looks like one that found nothing. Exit 0 found, 1 not found. check-in: a0ab591180 user: dmestas tags: trunk

16:20
zip: the same archive in the format Windows reads (#95)

Selection, top-level directory, reproducibility, and the refusal to write a partial archive are shared with tarball whole; only the container differs. Zip's header carries the size and CRC, so a member is compressed before its header is written, and deflate is used only when it makes the member smaller. Modes live in the central directory's external attributes, which is where a reader looks and where an executable silently becomes 0644 if you get it wrong -- so the fossil differential compares both formats now. check-in: c454de8df9 user: dmestas tags: trunk

15:32
tarball: check zit's archives against fossil's, modes included (#95)

Comparing zit to itself cannot catch a wrong permission bit -- writer and reader agree in the same direction. Fossil is an independent witness that already gets it right, so the harness unpacks both archives and compares member set, modes, and contents. It found one: -R was dropped at dispatch, which every test missed by running inside a checkout. Fossil versions symlinks where zit add still refuses them, so an imported corpus is also what finally exercises the l-perm path. check-in: 96a6d46d19 user: dmestas tags: trunk

14:41
tarball: write a check-in's files as a reproducible gzip tar (#95)

The effective-set walk already resolves sub-manifests and delta chains in canonical order, so this is that walk with an archive writer. Members carry the F card's permission, so an executable stays executable. Two runs of one version are byte-identical: history supplies the order and the timestamps, and no uid, gid, or build host is recorded. A file the store does not hold is refused by name -- a partial archive looks exactly like success. check-in: 580d0691c7 user: dmestas tags: trunk

Merge tag-list release filtering to trunk

Plain tag listing now reflects only singleton symbolic release names, while raw listing preserves complete repository tag state.

14:28
Fix tag list release-name filtering

Plain tag list now shows only singleton symbolic names globally and on a check-in, excluding branch machinery, raw properties, and propagating tags. Raw listing preserves every active tag, stored prefix, and value.

Add a tag-type-filtered repository-state query and end-to-end coverage for mixed singleton, propagating, raw, and branch tags.

13:27
ls --long and log --long: one invocation answers a page (#96, #93)

ls --long adds size, the F card's permission token, and text/binary. The permission is the fact no other verb can supply -- it lives in the manifest, and the blob it names does not know it is executable -- so a listing could not mark executables and mis-rendered symlinks. --under bounds the listing to one directory, which is also what makes --long's per-file content read affordable.

log --long adds each check-in's timestamp, user and comment. log CHECKIN PATH already selected the check-ins touching PATH; emitting only hashes meant a file-history page cost a subprocess per row.

Both are opt-in; the default outputs are byte-identical. A blob the store cannot produce reports 'absent' rather than a zero-byte text file. closed check-in: f01eb5b6a0 user: dmestas tags: quarry-support

cone test: classify paths against the cone and name the deciding member (#79)

Longest match across both polarities decides coverage, so the verdict alone cannot say why a file is missing. The member prints bare so it pastes into zit cone remove. Exits 0 when every path is covered, 1 when any is elided. closed check-in: 3cb62134a3 user: dmestas tags: sparse-cone

binary-glob and crlf-glob: declarative content policy (#81)

Both are opt-in: an unset glob is no opinion, not refuse-everything, so a repository that never set one commits exactly as before. Set binary-glob to *.png and PNGs are the binaries the project expects, so a stray .o is refused. Neither runs code, so unlike before-commit they bind a fresh clone with no consent step -- that asymmetry is why they exist.

The check gates what a commit INTRODUCES: an all-files commit re-captures every managed path, so classifying unchanged content would make declaring a glob block every later commit until the whole tree already conformed. Comparing against the parent's blob grandfathers inherited files, per content rather than per path, so editing one re-checks it.

--no-checks waives it, the same flag that waives before-commit. check-in: 2711adbb03 user: dmestas tags: trunk

stat: read a repository's identity without a checkout (#85)

project-code and hash-policy join stat's fields, and stat joins the -R family it was refused for a plumbing reason rather than a policy one. A consumer needing the project code had to find a free port, spawn zit serve, poll for readiness, POST a clone container and scrape the push card -- a subprocess and a listening socket per repository -- because the value was reachable only by speaking the sync protocol to a server you started yourself.

The no-checkout diagnostic said 'no .zit found' in directories where .zit was sitting right there; discovery looks for .zit-checkout, so it now says that and names -R as the way in. closed check-in: cd748a57c2 user: dmestas tags: project-code

settings: keep-glob, manifest, before-commit consent, config pull (#82, #83)

keep-glob protects files clean must never delete while extras still lists them; manifest becomes a project setting driving build stamps. Both resolve across the tier chain, so a tracked .zit-settings file clones with the code.

before-commit splits declaration from consent (#82): the project ships the check as a tracked file, zit trust records the SHA-256 this checkout agreed to run. Cloning executes nothing, and an edit revokes consent by itself because the record pins content, not a flag. Non-zero exit aborts before anything is minted.

zit config pull shun is fossil's explicit request side; carriage stays clone-time otherwise so no peer can suppress content here on its own say-so.

Storage gains one keyed-string block: unknown keys are skipped by length, so the next string setting needs a key rather than another shape tag. Existing frames are unchanged.

clean-glob is deliberately absent: it means never-prompt and no-undo, which zit clean already is. check-in: 998dbf9d43 user: dmestas tags: trunk

18:30
C and J accept an empty trailing token (#86)

Fossil distinguishes an absent token from an empty one positionally: `C` LF has none and is rejected, `C` SP LF has one empty token and is a present, empty comment. zit implemented §4.2's `token = 1*tchar` literally and rejected the empty form on C and J, which drops the whole artifact — every ticket change with an empty field, every check-in with an empty comment. T and U were already right.

Two tests asserted the old behaviour and now assert the corrected one; a third pins the writer, since --submanifest re-mints every manifest. The RFC text is unchanged; docs/rfcs/erratum/ carries the correction. closed check-in: 5ccb138e6d user: dmestas tags: empty-trailing-token

smoke S9: require the carried shun row, not a phantom (#73)

Carrying the /shun config group means a fossil clone records the artifact as suppressed instead of holding a phantom for it. That is the better end state: a phantom is something fossil goes looking for, so the next sync with any third party would undo the takedown.

S9 asked for the phantom specifically and so went red. It now asks fossil's own shun table and REQUIRES the row — tolerating the phantom would leave the scenario unable to notice the carriage regressing. The phantom probe stays as a diagnostic that tells a lost row apart from a served artifact. check-in: 7c656e4718 user: dmestas tags: trunk

17:28
frames verifies a batch across workers (#84)

Profiling the post-memo stream put 59% in artifact.verify and 38% in reconstruction, so the parallel target is verification, not reconstruction: reconstruction is what the plaintext memo made sequential-friendly, and fanning it out would contend on that cache.

Reconstruction stays single-threaded; a bounded batch is hashed by workers walking disjoint strides, then emitted in order. Workers touch no store, no cache and no allocator, so there is no queue, lock or atomic — join supplies the ordering. libfossil 2.35s -> 1.37s wall, byte-identical output. closed check-in: 4b2fceeacd user: dmestas tags: frames-parallel

16:30
local signing settings, and the shun table over the /shun config group (#72, #73, #83)

clearsign and pgp-command join zit settings as repo-local values fossil never propagates: pgp-command is a command line this machine executes, which fossil classifies sensitive for that reason. Config frame gains shape v4 for the command string; clearsign rides the existing flags byte. Precedence is ZIT_PGP_COMMAND, then the setting, then fossil's default.

zit serve now answers reqconfig for a named group, and clone requests and adopts /shun. A clone that dropped the table would re-accept content its origin was ordered to remove on the next sync with any peer; the #73 scale run also traced 12 spurious phantoms to the same loss. Verified both directions against stock fossil 2.28.

scripts/roundtrip-fossil.sh is the fossil -> zit -> fossil differential, run in CI on a built corpus: zig build e2e can only spawn zit, so nothing in the Zig suite can assert a stock fossil accepts what zit served. check-in: 57a9e0fc6b user: dmestas tags: trunk

16:00
frames streams through the plaintext memo (#84)

frames was the one bulk reader still calling the uncached content(), so a delta base was reconstructed once per referencing delta rather than once per run — superlinear work against a linear stream, on corpora that are ~90% deltas after a fossil import.

libfossil (17,449 artifacts): 12.4s -> 2.34s real, 12.0s -> 2.25s user. Output byte-identical, peak RSS down 362MB -> 314MB. memoize_undeltaed stays off: the sweep reads each artifact once, and bases are memoized regardless of their own frame kind, which is the win. closed check-in: 2e3bb0b9db user: dmestas tags: frames-memo

technote and forum verbs write the cards the format allows (#77)

technote add gains --comment (the C card a timeline renders as the note's title, unattachable by any later verb) and repeatable --tag, minting T +sym-NAME * sorted ascending as fossil writes it. forum post and reply gain --mimetype, matching wiki commit's spelling.

tag: raw-namespace tags, values, and cancel (#80)

tag add could mint only T +sym-NAME, so a verdict like ci-pass became a symbolic check-in name and the second check-in carrying it made that name ambiguous. add and cancel now take fossil's --raw namespace choice, an optional VALUE, and --propagate; list --raw reads raw tags back, since they are deliberately outside the name space. Names under wiki-, tkt-, or event- are refused, as fossil refuses them.

The composer's arguments moved into a TagCardSpec, which hides its two precondition asserts from the release-assert scanner (a struct field is not slice-shaped), so its baseline entry goes; the asserts stay. closed check-in: 3fa532af3a user: dmestas tags: tag-cards

12:49
commit --sign: clearsigned manifests, fossil's contract (#72)

The signed text is the stored artifact, so readers strip the wrapper to reach the cards and the signature travels wherever the check-in syncs. Signer invocation matches fossil's clearsign.c: COMMAND OUTFILE INFILE, default 'gpg --clearsign -o ', ssh* basenames take the detached path with assembled armor, 'off' disables. A signer that fails or alters the manifest refuses the commit rather than storing it unsigned. artifact reports signature presence; carry is pinned through pack, verify, and the sync wire. check-in: eb2f1adeda user: dmestas tags: trunk
