Timeline

The default-format timeline inflated a manifest per row — the fetch condition still said 'a.format != .oneline' from when oneline was the default, so zit#170's medium default made every row read one for two strings the image now carries. 66.5s to 0.37s for the full SQLite timeline, output identical.

Repository.manifest counts its reads (ZIT_MANIFEST_READS=1 reports on exit), and an e2e runs ten listings over two history sizes and requires identical counts — a per-row reader fails by construction, no timing, no constants.

zit leaves read and parsed a whole manifest per row — through its delta chain — for the comment's first line and the login. A warm store is image-backed and the image carried neither, so commentOf answered null and every row fell back to that read: 472 leaves, one second, on sqlite.

The image now materializes both: the comment CSR-addressed per rid, the login interned (a repository has a handful of committers). layout_version 6 — an older image is a miss and rebuilds, as the disposable cache intends.

0.3.2. check-in: 71d327a695 user: dmestas tags: trunk, version-0.3.2

The derive built the complete effective file list for every check-in and its parent, then compared them — O(files) per check-in, which on pkgsrc is 100k entries twice over, 305k times. Fossil's add_mlink merges the two deltas' own F cards and seeks the shared baseline; do the same, and walk the lists side by side when the baselines differ instead of materializing them. Keeps recently-read manifests parsed, pinned while a step holds them.

Twelve-character hashes and the weekday in day headers and leaf lines are the departures; -F oneline keeps the one-line timeline for scripts. check-in: 16c197b4dc user: dmestas tags: trunk

Twelve-character names and the weekday in the times are the only departures from Fossil's shape. cli.shortHash and cli.humanTime are the primitives the rest of the terminal-speech work builds on. check-in: d72b6372ab user: dmestas tags: trunk

Both found by running one session through fossil and zit side by side. check-in: a0690841c1 user: dmestas tags: trunk

A bare 'zit update' was a usage error; Fossil's means --latest. check-in: b618fc675d user: dmestas tags: trunk

The converter's hints are the source's own chains and each manifest's parent, so one delta usually settles it; the best-of-N window is the fallback. Conversion is now faster than the old convert-then-pack. check-in: 598d040de5 user: dmestas tags: trunk

Blobs take the flat source's own delta base as the hint, manifests their parent, carried artifacts the recent window. A 28x full-form gap on a toy corpus became 1.3x of packed, with no second pass and no double-disk peak. check-in: 38b9743ff8 user: dmestas tags: trunk

Fossil parity on the everyday verbs, landings and strata, protected branches behind a trusted front, Fossil's user table, and the read paths that now scale with the change rather than the store. check-in: 1e2a7bbc0d user: dmestas tags: trunk, version-0.3.0

Runs quarry ui on the checkout root with the terminal inherited; the binary comes from ZIT_QUARRY or PATH, and an absent one is a three-line pointer, exit 1. check-in: 95553946e3 user: dmestas tags: trunk

--by writes a side-by-side page under $TMPDIR and opens it from a terminal; -F html renders the timeline as a table; ui names quarry's local mode and exits 1 until it exists. check-in: 87f4be2914 user: dmestas tags: trunk

The two new settings ride the keyed config block; a configured editor makes commit editor-capable without a terminal. check-in: 7d9dcb2de1 user: dmestas tags: trunk

--merge three-way merges a stashed change into a dirty file; conflicts get markers, are listed, and exit 5 with the entry kept. check-in: 21ce2c785d user: dmestas tags: trunk

The checkout record carries the integrated leaf's hash as an optional sixth field; commit closes it with the same control artifact branch close mints. check-in: 2a522aab40 user: dmestas tags: trunk

-Z is -w; -N is accepted (an added file's hunks already carry it all). check-in: 39c88046ab user: dmestas tags: trunk

The managed set records one pending rename per moved file. mv moves files into a directory or a tracked directory as a unit, --soft records without moving, -n previews. revert -r VERSION restores another check-in's content; revert/undo/redo -n name what they would touch. add -f takes ignored files; clean gains -n/-f and --emptydirs. check-in: ece16d74a9 user: dmestas tags: trunk

branch new/close/reopen/hide/unhide/current/info. clone DIR defaults from the URL and is followed by open (--no-open keeps the bare store); open URL delegates to clone. check-in: 5d2f9a7e6e user: dmestas tags: trunk

timeline gains -b/-c/-p/-u filters, -r and --offset, -F medium|full (a date header per day, *CURRENT* on the checkout's check-in, user and tags) and -v for changed files; the default line is unchanged. status gains --classify (Fossil's words, aligned), --added/--edited/--missing/--conflict/--extra/ --differ filters, -v's header block, CONFLICT for an edited file still carrying markers under a pending merge, and MERGED_WITH. pull, push, sync and remote accept -R, so a bare mirror needs no working tree. current/ ckout/prev/next take effect in these verbs through the same hint. Refs zit#163. check-in: 6c84f304f4 user: dmestas tags: trunk

update prints Fossil's receipt on stderr (per-file UPDATE/ADD/REMOVE/MERGE/ CONFLICT, the from/to block, the undo hint) and gains -n, --latest and -v. Every sync-family line names the peer, a no-op is always 'already in sync', clone prints the project code, an unreachable peer is named, and pull/push/ sync show per-round progress on a terminal. commit takes -M FILE, composes the comment in $VISUAL/$EDITOR/--editor over a template of the change set (kept in .zit-ci-comment when the commit then fails), and gains -n and --allow-empty; --no-warnings is accepted as Fossil's spelling of --no-checks — the content gate stays opt-in by design. The names current/ ckout, prev/previous and next resolve against the checkout. The muscle harness now enforces all of it. Closes zit#157, zit#158, zit#159, zit#160, zit#161. check-in: e5beabd7c0 user: dmestas tags: trunk

zig build muscle runs one scripted session — 27 lines a Fossil user types most — through the real fossil and the real zit against local servers, and compares each step's exit-status class and whether the verb spoke at all. Deliberate divergences carry their reason, known gaps carry their issue; anything else fails the run. CI runs it beside smoke. Closes zit#162. check-in: 741f6d428b user: dmestas tags: trunk

Any unambiguous prefix of a command dispatches (zit up, zit tim); an ambiguous one names its candidates; an exact verb always wins, so stat stays the store census. Aliases: ci/checkin, co/checkout, changes, delete/forget/ remove, rename, blame/praise, new. A token of three letters or fewer is only suggested at edit distance 1, and an unknown verb prints two lines, never the command list. Closes zit#156. check-in: e114f7a174 user: dmestas tags: trunk

repo.files re-read and re-parsed the B-card baseline for every delta check-in — 79% of the mint phase on pkgsrc. Repository.filesMemo takes a caller-owned BaselineMemo keyed by artifact name; consecutive deltas over one baseline borrow the parsed manifest and read nothing. On a 30k-file history of 300 deltas, source enumeration went from 10s to 0.3s and the conversion from 13.5s to 3.7s, every check-in hash identical. The memo holds a heap entry with a stable address; the optional-by-value form did not persist under ReleaseFast. Closes zit#167. check-in: c80728261e user: dmestas tags: trunk

The rebirth arm of import-fossil required a zit store, so the verb that says 'import a fossil' could not take one. It now accepts the fossil's sync URL like --compatible does, cloning a transient flat store beside DIR and removing it after; a local store stays accepted. The zit->zit conversion gets its proper home as 'zit submanifest convert SRC DEST', beside 'enable', which now says what it does not do: existing check-ins stay flat, and fossil peers receive nothing new from the next commit. Diagnostics carry the verb the operator typed. Closes zit#168. check-in: abd850dc4c user: dmestas tags: trunk

The gate replayed every commit through the from-scratch tree builder three times to predict what the conversion itself measures, and on pkgsrc that was 14 of 26 hours before a byte was written. The conversion writes a new project beside an untouched source, so the honest evidence is the converted store: the summary now reports its bytes against the flat source's. The partition parameter comes from --k or the tip sweep; a history no k partitions is refused, as 'submanifest enable' refuses it. 'zit submanifest analyze --replay-all' keeps the model for anyone who wants it first. Closes zit#129. check-in: 04d944c1dd user: dmestas tags: trunk

Every check-in went through artifact.buildTree from scratch, so a wide tree cost its whole file set per commit against a few changed slices actually written. The converter now applies each check-in's change set over its primary parent's root with TreeEditor — the commit verb's builder — keeps a parent cache released as children consume it, interns the retained cards, runs the pair proof through the run-scoped flatten memo, and parses each source manifest once. The Git importer's LogTreeStore moves to a shared module. Output is unchanged: every check-in hash matches the from-scratch build on libfossil and on a 30k-file synthetic history. Refs zit#167. check-in: 5e0155427e user: dmestas tags: trunk

The converter only stripped PGP armor, so an SSH-signed check-in re-minted with its envelope inside and failed its own verify silently. Verification now runs as each pair is minted, the census counts come from the first pass instead of a second corpus read, and --k narrows the gate's replay to one arm (skipped with --force). Each phase reports its wall time on stderr; the summary points at 'zit pack'. Closes zit#155. check-in: 75c8669553 user: dmestas tags: trunk

Their repository and global tiers, and config's user/shun areas, all live in the store, not the working tree -- fossil serves them under -R too. Move both out of the -R blanket refusal, resolve the override, and name a bad -R path with the #97 diagnostic rather than the discovery message that advises the flag already given.

The reverse of accept, through the same ephemeral-checkout merge, now one function that does not know which direction it runs. Always merges in a working area of its own, checkout or not, so a tree is never left half-merged. Up to date is exit 0 with nothing written; a conflict is refused with its paths; a settled record is refused; a stacked landing is not, since refreshing a rung is what the rungs above it need. The refresh is a reply in the record's thread. Issue #152. check-in: c4b949ebbf user: dmestas tags: trunk

A self-targeted +sym-B is not how a branch is joined, but nothing legitimate mints one on a protected name. maintain now derives the fast-read image only when the log grew, so a pull-heavy fronted server does not pay an image load per connection. Pins that a merge with a protected secondary parent stays on its primary's branch. Issue #151. closed check-in: 13760d0c92 user: dmestas tags: serve-protected-branches

A front that authenticates every push knows who is pushing; the store knows which branch a pushed check-in resolves to. The front sends only the rule -- X-Zit-Protect, a glob list -- and zit serve --fronted refuses the whole round when a check-in would join one of those branches or a tag would move a held check-in in or out of one. Same error card as a content-policy refusal, so a stock fossil client reads it.

Without --fronted the header is ignored and the server is unchanged. Nothing new on the wire or in the repository. Resolution is crosslink's own, through the fast-read image, which maintain keeps warm between connections. A parent not yet held is admitted: it is judged on arrival. Resolver faults fail closed. Issue #151. check-in: 63ec7d6dc8 user: dmestas tags: serve-protected-branches

comment collapsed the G and I cards onto the record root, so a landing thread could not branch. Split mintForum's root and reply-to; landing comment takes --reply-to POST, resolving the thread root with the same helper forum uses and refusing a target outside the record's own thread. closed check-in: fed51b20cb user: dmestas tags: landing-reply-to-149

An unguarded vector parses as a real artifact, so Fossil crosslinks it into every clone -- two check-ins, a technote, twelve sub-manifest slices and a phantom pair that sync chases forever. Each vector now carries a leading # block; rfc_vectors.zig strips it at comptime so callers still see the exact RFC bytes.

Background and the cleanup that follows: see wiki page 'rfc-vector-ledger'. closed check-in: 32ef56aaf4 user: dmestas tags: rfc-vector-guard

A complete SHA-1 name is shorter than max_hash_len, so it missed the full-width fast path and fell to the O(store) hex scan -- once per file under `ls --size` and `ls --long`. On tcl's tip the 545 SHA-1 named files cost ~54ms each against ~0.2ms for the 1,653 SHA3 ones.

The directory is ordered by raw digest, so a prefix's matches form one contiguous run. A binary search for the run plus a walk of it proves uniqueness rather than assuming it, which is what the SHA-1 case was surrendered to the scan for. Odd-length prefixes end mid-byte and keep the scan.
