zit 0.3.8

zit 0.3.8 gives annotate a real diff core, lets info answer many check-ins in one call, and closes the last corners where fossil and zit could read the same checkout differently.

No artifact, tag namespace, or sync message changed.

annotate on a diff core

annotate compared versions with an O(n×m) LCS and re-derived a manifest at every step of the walk. The crosslink record now carries each changed file's artifact hash — fossil's mlink shape — so annotate reads blobs by hash, and merge3 moves to a linear-space Myers LCS. Plaintext and baselines are cached across versions. On the sqlite corpus annotate src/shell.c.in went from 57 s to 3.1 s; fossil takes 2.3 s at its default version limit and 4.4 s with --limit none.

Output is byte-identical to the previous build. Attribution still differs from fossil's on merged lines, by design: zit credits a line to the oldest check-in that carries it and merged lines to their origin branch, where fossil credits along primary parents. Help now states the 12-character prefix annotate actually prints.

info takes many names

zit info A B C answers every name in one process, and - reads the names from stdin. -F json emits one object per line. A name that fails to resolve goes to stderr and the run continues, exiting 1 at the end. A forge rendering a page from hundreds of info calls does one spawn instead of hundreds.

One checkout, two tools, the last corners

• Glob classes. In .fossil-settings and .zit-settings globs, ! is a class member and only ^ negates, as in sqlite's GLOB. The .zitignore (gitignore) dialect keeps !.
• A versioned-only manifest setting is read out of the check-in at open, the way fossil's db_get_versioned does, so the stamps appear on the first checkout rather than the first update.
• open --manifest=off is remembered. A project setting cannot re-enable stamps at the next update. --manifest=on, yes, true, and 1 mean ru.
• add --force means what it means in fossil: a file named directly is added even when ignore-glob matches it. A directory expansion always honours ignore-glob and clean-glob; a named ignore-glob match without --force is skipped with a note, a named clean-glob match is added silently. changes after either step is byte-identical to fossil's, and the differential smoke now checks it.
• .fslckout, _FOSSIL_, and .fos at the root match case-insensitively on macOS and Windows only; Linux compares exactly, as fossil does.

Behaviour changes

• [!abc] in a fossil-dialect glob no longer negates the class. Rewrite as [^abc].
• zit add FILE where ignore-glob matches FILE now skips it and says so; --force adds it. zit add DIR no longer adds clean-glob matches.
• zit open without --manifest follows the project's versioned setting from the first checkout.

Compatibility

• Artifacts, tags, and the sync protocol are unchanged; Fossil RFC revision 00 remains the target.
• The cache format changed: the crosslink record is at format 5 and the checkpoint at format 5. A cache written by 0.3.7 is re-derived once on the first open; nothing needs to be run by hand.
• Flags added: -F json and - (stdin) on info; --manifest=on|off on open. Output changes only where the section above says so.

Qualification

zig build test, e2e, smoke (Fossil interop against a real fossil, now with the add --force scenario), muscle (41 differential steps), git-import-e2e, git-export-e2e, and dst, plus the three-runner CI battery (macOS ARM64, Linux x86-64, Linux ARM64). annotate timings were taken on the sqlite corpus with release builds; attribution and changes output were diffed against fossil 2.28.
