Timeline

pull/push/sync loaded every artifact into memory before the first wire byte -- 3.7GB resident on a 148k-artifact store, OOM beyond it (#119). The client now sits on LogIndexStore as serve does: names, held/phantom, shun mask, and hash-policy off the frame index, content materialized per-rid on demand, received artifacts in the appendix. No-op pull on tk: 3.7GB -> 88MB, 64s -> 13s. check-in: 46d49702f7 user: dmestas tags: trunk

Record (mtime, size, hash) per tracked file in .zit-cache/treestat after each scan; a matching stat answers without reading. Fossil's vfile heuristic (D. Richard Hipp), race window included. Advisory tier rules: malformed parses as empty, deletion costs a re-hash, never an answer. check-in: f34bbc730a user: dmestas tags: trunk

Both sides had made the repository-tier setting read adopt the scan index (#112); trunk's write-on-miss refresh is kept inside the shared helper the autosync read now also uses. check-in: 6f540c5d77 user: dmestas tags: trunk

A repository cloned from a Fossil server carries its versioned policy in .fossil-settings/, which zit ignored entirely -- extras, addremove, and clean answered differently from fossil on the same checkout. Every versionable setting now reads fossil's spelling first and zit's as the fallback, through the one resolver funnel; the ignore seam and the shadow note follow. Settings zit does not model stay unread. check-in: 296f2e5cc2 user: dmestas tags: trunk

Stage payloads once and rename them into place instead of writing them twice with an fsync each; keep the parent directory open across a path-sorted plan instead of re-walking it per file; read the repository setting through the persisted log index instead of a full frame scan; reuse the verb's open repository for the target's branch facts rather than deriving repo state a second (update: third) time.

tk (146k artifacts, 1,079 files): open 1.1s -> 0.48s; fossil is 0.34s. Rename-into-place also closes the checkout_sweep H2 finding: no crash cut can leave a hybrid file, so the pinned test now asserts that. closed check-in: 244523acfa user: dmestas tags: materialize-perf

open() resolves root_dir to the store's home, which for a detached worktree is another checkout's directory -- so currentCheckoutRid read THAT checkout's .zit-checkout, and leaves, branch, bare ls, and the update/merge plan base all took the other tree's branch as current while status told the truth. A new checkout_root field carries the invoking directory; checkout-state reads use it. Pinned by a two-checkout e2e asserting every verb stays in its own tree. check-in: 6f0ba0fd3d user: dmestas tags: trunk

repositorySetting opened the store with a bare openReadOnly -- a full frame-header scan to reach one config frame, 5.6s on a 1.17M-artifact store, and blind to the .zit-cache scan index because it had no directory in hand. It now takes Repository.logStore's own fast path: adopt the persisted index, resume over the tail, refresh on miss, with the cache directory resolved through the checkout's store pointer so a worktree never grows a stray sidecar. 5.6s to 0.12s. check-in: cf01ef34ba user: dmestas tags: trunk

serveAnswer resolved binary-glob and crlf-glob through a fresh LogStore.openReadOnly per setting per round -- a full frame-header scan each time, ~11s per round on a 1.17M-artifact store, turning a clone into half an hour of server CPU. The snapshot's per-build config read now carries the pair, like the submanifest facts beside it; freshness rides the same (size, mtime) key. Server CPU for the same 181-round clone: ~34 minutes to 15 seconds. check-in: 262ca49578 user: dmestas tags: trunk

An mtime divided by a day is already the day number Joffe's identity consumes (benjoffe.com/fast-day-of-week), so the UTC weekday falls out with no calendar decomposition. Flag-gated; unflagged output is byte-identical, pinned by test against a Sakamoto reference over 40,000 days.

log --long's record grammar is now a stated contract: consumers parse it positionally and no display option will change it. The flag skips info, which prints no date line. check-in: 4652c5cc31 user: dmestas tags: trunk

The record body now captures the U-card user and the changed-file set, diffed against the primary parent at derive time where the parsed manifest is already in hand (layout 5, checkpoint 4; one-time rebuild per store). 'zit crosslink' replays it: identity, comment, tags, and file changes as a versioned text stream, cache-served under the same key discipline as every read verb, byte-identical to --no-cache.

sqlite dumps 36,797 check-ins in 0.11s / 14.9MB against the 3.87GB structural stream. A parent the store does not hold reads as 'files unknown', never as an empty change set -- sqlite's corpus carries exactly one, a 2009 check-in with a genuinely absent parent.

Mixed binary versions thrash across the layout bump: each side rejects the other's cache and re-derives. Update every binary that shares a store. check-in: 2a68d2fc79 user: dmestas tags: trunk
