Timeline

zit clones go-libfossil's flat history through a cone, and both sides must report the same number of elided phantoms over the same cone. Each side then commits over its sparse store and pushes to a dense store of the other. The commit carries no R card, and the receiver holds the whole check-in. check-in: 0a63c3b22f user: [email protected] tags: feat/submanifest-reader, main, trunk

Cases elide out-of-cone blobs from a dense clone, as a cone-scoped clone would leave the store. They check the three absence classes, the client and server sync filters, recomputation on a cone change, loss of the cone (unreadable, or dropped by fossil rebuild, after which fossil's pull heals the store), verify and rebuild counts, R-card omission and skipping, a commit over elided subtrees pushed to a dense peer, widening, hybrid histories, and delta bases.

Holding out-of-cone sub-manifest nodes is recorded as a deviation from §5.1. zit holds them too, because a tree that cannot be enumerated never links.

A checkout's record names the phantom for a file that neither cone covers, so a checkout opens over a sparse store. check-in: b907b41650 user: [email protected] tags: feat/submanifest-reader, main, trunk

The client's phantom load and the server's request_phantoms skip elided phantoms (draft-fossil-sparse-cone-00 §5.2). A dense store classifies nothing and behaves as before. Repo.StoreCone and Repo.SetStoreCone expose the store cone. check-in: 37f15485b4 user: [email protected] tags: feat/submanifest-reader, main, trunk

A commit over a store with a store cone leaves out the R card (draft-fossil-sparse-cone-00 §4.3). It refers to out-of-cone files the store lacks by hash alone (§5.3). VerifyRCard skips over a sparse store, and skips a manifest that has no R card, since an absent R card is not damage.

verify.Report gains Phantoms (transit) and Elided. Neither is an Issue, so a store complete within its cone verifies OK (§5.2). Rebuild keeps the store cone and reports the same counts. check-in: cd98ba38cb user: [email protected] tags: feat/submanifest-reader, main, trunk

The store cone (draft-fossil-sparse-cone-00 §5) is kept in a storecone table that exists only while a cone is set. fossil rebuild drops tables it does not know, so losing the cone reads as dense and the store heals toward dense (§5.2). A cone that does not parse also reads as dense.

LoadAbsences sorts every phantom into transit, shunned or elided by zit's rules. A phantom is elided when F cards name it only outside the store cone and no held delta uses it as a base. check-in: 524c749185 user: [email protected] tags: feat/submanifest-reader, main, trunk

A zit older than check-in 0431958ff4 gates trees on the announced version, so against it the interop tests fail on the protocol change rather than on anything go-libfossil does. zitBinary now probes the binary for the pragma's name, which a zit that sends it carries; zit's version cannot tell, since 0.5.0 was tagged before the change. An older zit is skipped with its path, version and the check-in needed, or fails the run under REQUIRE_ZIT_BIN=1 as a missing one does.

Tracked in #452. check-in: b9c7364ff2 user: [email protected] tags: feat/submanifest-reader, main, trunk

Save reads each changed file through vfile.Disk, so a symlink is stashed as its target's name and recorded with file_islink, and its revert makes it a link to the committed target. Apply writes a stashed symlink as a symlink and deletes a link before writing, so neither writes through one. check-in: 5be36b41a0 user: [email protected] tags: feat/submanifest-reader, main, trunk

restoreCommitted writes through vfile.Disk with the row's islink, so a repointed link is made a link to its committed target again instead of having that name written into the file it points to. check-in: 6a440bc42f user: [email protected] tags: feat/submanifest-reader, main, trunk

Move checkout's link-aware diskView into vfile.Disk, so checkout, undo and stash share one RepoFILE view: Stat, Read, Write (which deletes a link before writing, makes a symlink when allow-symlinks is on, creates the directory and sets the executable bit as file_setexe does), SetExe, MTime and Remove. The allow-symlinks setting is read by vfile.OpenDisk.

undo.Save, Undo, Redo, Swap, ReadFile and RestoreFiles now take a Disk: a symlink is read as its target's name and recorded with isLink, and is deleted and made a symlink again on restore, as undo_save and undo_one do, so Undo of an Update no longer writes through a link. check-in: 858c20561f user: [email protected] tags: feat/submanifest-reader, main, trunk

zit retired the sub-manifest draft's provisional phase the same day as the send-submanifests errata (erratum submanifests-00-s8.2-provisional-phase- retired): §8.2 is gone, and its one permanent rule, that the setting must not be enabled on a repository a non-reading peer serves, moves to §8.1. zit's enable warning now states that rule in place of the disposable- fixture text, so go-libfossil's, worded as zit's, does too.

The conformance suite pins the draft at zit check-in bbc6794bf0, the revision dated 19 October 2026 whose Appendix C lists the nine errata it applies; the Appendix A vectors are unchanged.

Tracked in #452. check-in: efba058666 user: [email protected] tags: feat/submanifest-reader, main, trunk

An add at a rename's old name ends as fossil's revert leaves it, by every name the revert can be given, and Undo restores what fossil undo does. A three-file rotation and a chain reverted by its middle name end under their committed names; reverting only a chain's second rename keeps the first one pending.

Tracked in #248. check-in: 4bec3ce730 user: [email protected] tags: feat/submanifest-reader, main, trunk

Covers the rename and dry-run paths of Update's symlink conflict: the link is listed in Unmerged, nothing is written through it, and only a real run deletes the old name, as fossil's update does. check-in: ef49615d6c user: [email protected] tags: feat/submanifest-reader, main, trunk

draft-fossil-submanifests-00 §7.2 no longer gates S-bearing artifacts on the peer's announced version: fossil 2.29 announces 22900 and reads no tree. A peer that reads trees now says so with pragma send-submanifests, which go-libfossil sends in every request right after client-version and in every reply, clone replies included, right after server-version, whatever the sub-manifest settings. The version threshold and the 22900 reader marker are gone; client-version and server-version announce 22800, the fossil release whose protocol this library speaks.

A tree manifest or sub-manifest is refused to a peer that has not sent the pragma with "Peer does not accept sub-manifests.", never converted or omitted. A server decides from the whole request it answers, a client from the replies it has received in the exchange. avoid-submanifests moves from the ci-lock answer into the same leading run of every reply.

Enabling emission over a stored submanifest-k outside 1 to 12 without an explicit k is refused, naming the stored value (§8.1).

The conformance suite pins the draft with the 2026-10-19 errata applied: SM-7.2-1 and SM-6.3-3 are met rather than deviations, SM-7.2-2, SM-7.2-3, SM-6.3-1/2/7 and SM-8.1-3 follow the corrected text, and SM-7.2-4 covers the pragma's placement. The zit interop pushes a tree go-libfossil wrote to zit and checks both sides refuse trees when the pragma is stripped.

Tracked in #452. check-in: 05a53c393d user: [email protected] tags: feat/submanifest-reader, main, trunk

Checkout.Revert refused to undo a rename when another file held the old name: a swap, a chain, a new add or an untracked file there. Like fossil's revert it now saves each file it writes or deletes for undo, then reverts in one transaction, so Undo or fossil undo brings back what it overwrote, and a failed revert puts the files back.

Undoing a rename takes back the old name from whatever row holds it: a row renamed onto it is reverted to its own old name, and any other row is dropped, as fossil's UPDATE OR REPLACE drops it. Every committed file ends under its committed name; fossil's own revert leaves a swap renamed and stops tracking the second file of a chain.

Tracked in #248. check-in: 80764da743 user: [email protected] tags: feat/submanifest-reader, main, trunk

A file outside a sparse checkout's cone is never on disk, so it read as missing, hence changed, and followed the target's rename; any upstream rename outside the cone then refused the update. It is now classified before renames are followed and matched by name: a rename outside the cone moves only the record, one into the cone writes the file under its new name, and an unedited file renamed out of it leaves the disk.

A symlink edited locally and changed by the target was merged through the link, writing conflict markers into the file it points at. As fossil's update does, it is now a conflict with nothing written, listed in UpdateResult.Unmerged; a rename still removes the old name. check-in: f373c9a8ae user: [email protected] tags: feat/submanifest-reader, main, trunk

The cones merge called extractSingleFile without the islink argument the symlink fix added, so it did not build. SetCone now passes the row's islink, and a file entering the cone is written as Extract writes it: a symlink with allow-symlinks on. check-in: 36fccc1f87 user: [email protected] tags: feat/submanifest-reader, main, trunk

# Conflicts: # internal/checkout/update.go check-in: 6708292b55 user: [email protected] tags: feat/submanifest-reader, main, trunk

Since the scan began recording islink and chnged 7/9, Create followed by Extract without Force failed on any repository with an "l" file: the file was missing, the scan read it as UNLINK, and the missing-file skip only covered plain edits.

Extract and Update now write a symlink entry as fossil's vfile_to_disk does: as a symlink to the blob content while allow-symlinks is on and the storage can make links, otherwise as a plain file holding the target. A symlink is deleted before a file is written over it, and setMergedMode leaves symlinks and directories alone, as file_setexe does. Extract's missing-file skip covers mode changes too, so the first Extract after Create plays fossil's open whatever the entry.

With allow-symlinks off, fossil itself reports such a file UNLINK and its checkout refuses without --force; Extract keeps that behavior, and an interop test pins it against fossil's open in both modes.

ScanENotFile no longer refuses a directory at a pending add or removal recorded with chnged=0, matching the else-if in vfile_check_signature.

Tracked in #449 check-in: 8cad365e82 user: [email protected] tags: feat/submanifest-reader, main, trunk

Update now follows the target's renames and saves undo state. A file outside the cone stays a record-only step: never written, chmodded, backed up or read for undo. A local edit that a rename would carry out of the cone is refused, naming the cone. check-in: 74aa290eda user: [email protected] tags: feat/submanifest-reader, main, trunk

# Conflicts: # internal/undo/undo.go check-in: d6ac19e580 user: [email protected] tags: feat/submanifest-reader, main, trunk

Stash save now scans the checkout first, as fossil's stash_create does (vfile_check_signature), so an edit no scan had recorded is stashed too. Save takes the scanner, a *checkout.Checkout, as its first argument.

Undo and redo no longer print to standard output: they return the files they changed, as []undo.Change, in the undo table's row order, the order fossil undoes them in.

Tracked in #448 check-in: 2dfae63b63 user: [email protected] tags: feat/submanifest-reader, main, trunk

Update saved no undo state, so nothing could reverse it. It now reads the file of every step that writes or removes one before writing, as fossil's update calls undo_save, and saves those files with copies of vfile and vmerge and the checked-out version in the same transaction that moves the checkout to the target. If a write fails partway the files are put back, as fossil's undo_rollback does.

Checkout.Undo and Checkout.Redo (internal and public) swap that state back and forth and keep checkout-hash naming the restored version. The undo package gains ReadFile, SaveTx and RestoreFiles, and its undo table now has fossil's schema (isExe, unique pathname, rowid order, the executable bit read from disk), so fossil undo reverses a go-libfossil update and Checkout.Undo reverses fossil update; fossil 2.28 interop tests check both. Under js/wasm, which has no undo package, Update saves nothing.

It is never checked against the user table; the check-in's rcvfrom row credits that login's uid when the table holds it and the local setup user otherwise, as fossil credits g.userUid whatever the U card says. A test pins that an unknown name commits under that name. check-in: 54c9e56786 user: [email protected] tags: feat/submanifest-reader, main, trunk

Receipt.ID took (rcvid, mtime) to identify its own row and checked it with a SELECT on every use. After a rollback the rcvid can be reused by another receipt's insert, and under a frozen clock the mtime matches too, so the receipt attached to the wrong row.

Fossil holds g.rcvid for its process and never re-reads the row (content_rcvid_init); a rollback ends the process with it. A Receipt outlives transactions, so the transaction or savepoint that makes its row now records that, forgets the id if it rolls back, and hands it to the enclosing level when released. A kept id costs no query, which takes one SELECT per stored blob off the clone path.

Also checks that a tree check-in's sub-manifests share the commit's receipt. check-in: 0269bd9461 user: [email protected] tags: feat/submanifest-reader, main, trunk

Update's rewrite meets the sparse worktree: a file outside the cone is a record-only step, counted in OutOfCone, and never planned, scanned, checked, written, backed up as NAME-original or chmodded; reloading vfile moves its record to the target. SetCone records the mtime of each file it materializes, as Extract now does. check-in: 47f89f0798 user: [email protected] tags: feat/submanifest-reader, main, trunk

Only macOS arm64 and linux-x64 fossil have been compared bit for bit, so the rebuild test no longer claims Windows is exact. julian.go says which long doubles fall back to 53 bits wrongly, and ExpandAll's doc says its errors match Cache.Expand's in kind, not always in wording. check-in: e4c84f20f9 user: [email protected] tags: feat/submanifest-reader, main, trunk

TestTextJulianDayMatchesFossil compared macOS arm64 fossil's stored values with the text form at the running platform's long double, so it failed on linux-x64, where fossil itself stores different last digits. TestTextJulianDayPerLongDouble already checks those values at 53 bits and linux-x64 fossil's at 64, so the platform-blind test goes. check-in: e499428d3b user: [email protected] tags: feat/submanifest-reader, main, trunk

checkCheckins now gathers into a staging report and copied only its issues back, so the MissingRefs count treeGap adds was lost: Verify reported a missing sub-manifest as an issue but counted zero missing references. check-in: 39b524c37c user: [email protected] tags: feat/submanifest-reader, main, trunk

The rebuild speed-up hands checkOneCheckin each check-in's expanded bytes and drops the pass-wide expansion cache. treeGap, from the sub-manifest reader, still lists a check-in's files to find a missing sub-manifest, and it needs a cache: without one every delta manifest re-expands its baseline. checkCheckins now keeps a small cache for those manifest reads only. check-in: 1a45812566 user: [email protected] tags: feat/submanifest-reader, main, trunk

fossil's printf carries a %.17g value in C long double: a 64-bit double on macOS arm64 and Windows, 80-bit x87 on x86-64 Linux. The 16th digit, and so the event time fossil stores, differs between the two for about one time in five, which is why TestTextJulianDayMatchesFossilBinary passed on macOS and failed against CI's linux-x64 fossil. SQLite is not involved: julianday() counts integer milliseconds and 3.52.0's text-to-double conversion is integer arithmetic, neither using LONGDOUBLE_TYPE.

fossilPrintf17g now runs fossil's algorithm in a big.Float with the significand width of the platform's long double (53, 64 or 113 bits). Against all 4,007 times fossil stored in the failing CI run, 849 of them different from macOS fossil's, the 64-bit form matches every one; the 53-bit form still matches macOS fossil. The binary128 width (arm64 Linux) follows the same arithmetic but has not been compared with such a fossil. Times written on one platform and rebuilt by fossil on another may differ in the last place, as two fossils do. check-in: 387204fa55 user: [email protected] tags: feat/submanifest-reader, main, trunk

A public check-in could reuse content first stored privately, say by syncing a private branch, and leave it in the private table. Sync never sends private blobs to a peer without private access, so that peer got a check-in whose file stayed a phantom and could not be checked out.

storeFileBlobs now calls content.MakePublic on each file blob inside the check-in's transaction, as fossil's commit calls content_make_public for each F card (checkin.c). The blob is already queued in unsent, so the next push carries it. The sub-manifest writer already does this for trees.

ticketInsert assumed ticket.tkt_ctime and ticketchng.tkt_rid/tkt_user, so crosslinking fossil's own repository failed with "table ticketchng has no column named tkt_user". It now probes the schema as fossil's getAllTicketFields does and writes as ticket_insert does: optional columns only where present, a ticketchng row only when the artifact sets one of its fields or the table records the artifact or its user, shared fields the artifact leaves unset copied from the ticket row, and the "baseline for NAME" column set to the artifact that assigns NAME.

A fossil-binary oracle derives three such schemas and requires the ticket and ticketchng rows fossil rebuild writes. check-in: eb234f62ad user: [email protected] tags: feat/submanifest-reader, main, trunk

A control artifact's 'g' event comment now matches fossil byte for byte: each target introduced by an Edit link, changes sorted by target hash and full tag name, sym- tags named as tags, a branch move linked to its timeline with its own sym- changes left out, values HTML-escaped, no leading space. tag.InsertControlEvent owns the row, and AddTag writes it, as fossil's tag add does; it was missing until a rebuild or clone.

Attachment comments link the attached artifact and the ticket or tech note as fossil 2.28 does, and a deleted attachment's src is NULL. A check-in without a C card gets a NULL event comment. Hash prefixes follow hash-digits up to 64 digits (was capped at 40); the printf helpers move to fsltype so tag, ticket and attachment comments share them.

Fossil-binary oracles: a fossil-made history with tags, branch moves, wiki, tickets, tech notes, forum posts and attachments rebuilt by both, and a go-written history rebuilt by fossil, must give identical event and attachment tables. check-in: 087e1c7ce3 user: [email protected] tags: feat/submanifest-reader, main, trunk

* fix(manifest): round a caller's check-in and tag time as fossil does

Fossil reads a --date-override through SQLite's strftime, which rounds the seconds to the millisecond (holding a fraction past .999 in its second) rather than truncating them. A caller time finer than a millisecond now gets the D card fossil would write for it; the default clock time is still truncated, as fossil reads its clock.

fsltype.CardTime and CardTimeNow are the one place both rules live, and the checkout commit path and branch creation take their default time through them.

* fix(repo): stamp config and user rows in seconds since 1970

Fossil writes config.mtime and user.mtime with its now() SQL function, time(0). SetConfig, SetHashPolicy and CreateUser wrote julianday('now') instead, so fossil read those rows as dating from 1970 when comparing times in a configuration merge, and SetCaps and SetPassword left the user's mtime alone where fossil's user command restamps it.

* fix(auth): read and write user.cexpire as a Julian day

Fossil keeps user.cexpire as a Julian day (src/login.c). A sync login parsed it as RFC 3339 or 'YYYY-MM-DD HH:MM:SS' text, so any value fossil had written failed to parse and the login was refused as expired. The expiry is now read through julianday(), which takes both forms, and repo invite --ttl writes a Julian day; its write error is now checked.

* fix(checkout): set file times as fossil's --setmtime does

Fossil's --setmtime gives each unedited file the time of the newest check-in, among the version and its primary ancestors, that recorded the file's content, truncated to whole seconds (mtime_of_manifest_file), and it does so for every unedited file of the version once the checkout is up to date (vfile_check_signature with CKSIG_SETMTIME). SetMTime gave every written file the target check-in's time to the millisecond, and an update left the files it did not write alone.

* fix(stash): keep and show stash and bisect times as fossil does

Fossil stores stash.ctime as julianday('now') and lists it with datetime(ctime); go-libfossil stored CURRENT_TIMESTAMP text, which the two drivers returned in different forms, and showed a fossil-written time as a bare number. bisect's list now shows datetime(event.mtime), as fossil's bisect ls does, instead of the Julian day.

* test(verify): fossil rebuild keeps the times go-libfossil stores

A repository go-libfossil wrote, with check-ins at caller and clock times, a tag and a branch, is rebuilt by the fossil binary, and every check-in event, plink and tagxref time must come back unchanged.

* test(sync): a fossil clone and push agree on every synced time

The fossil binary clones a go-libfossil server, unversioned files included, commits at a time finer than a millisecond and pushes back. Each side derives check-in event, plink and tagxref times from the artifacts itself, and the unversioned time travels on the wire; both repositories must then hold the same values.

* fix(resolve): bound NAME:TIMESTAMP with julianday() as fossil does

Fossil resolves BRANCH:TIMESTAMP with event.mtime<=julianday(BOUND). The bound was computed in the text form event rows hold, so on a millisecond where that form is larger than julianday()'s, a check-in at the bound itself resolved here and not in fossil.

* fix(manifest): round a caller's card time with integer arithmetic

CardTime followed SQLite's printing of the seconds as a double, which is not a well-defined rounding: at exact half-millisecond ties fossil 2.28's SQLite gives .124 for .1245 but .020 for .0195, and other SQLite versions differ again. A caller time is now rounded to the nearest millisecond on its nanoseconds, ties up, held at .999 as fossil holds it. The fossil binary test compares every non-tie value, across second, minute, day and year ends; ties are asserted on their own.

* fix(auth): ignore user.cexpire at sync login, as fossil does

user.cexpire is the expiry of fossil's web-login cookie: fossil sets it at web login, writes 0 at logout, and its sync login (check_login) never reads it. Refusing a sync login on it locked out anyone who had logged into or out of fossil's web UI, or whose cookie had lapsed.

The invite TTL that relied on it now lives in a config row of its own, invite-expire:LOGIN, as a UTC instant checked at sync login; repo invite no longer writes cexpire, and the expiry is no longer written in local time and read as UTC. Deleting a user drops its invite expiry.

Tracked in #441.

* fix(repo): convert Julian config and user mtimes on open

Repositories go-libfossil wrote before config and user rows were stamped in seconds since 1970 still hold Julian days there, which fossil reads as January 1970. Open converts those rows to the seconds they stand for. It checks first and writes only when a row needs it, so it converts once and takes no write lock on an up-to-date repository.

* fix(checkout): set a file no check-in recorded to 1970, as fossil does

With no mlink row for a file's artifact in the version's ancestry, fossil's max(event.mtime) is NULL, which mtime_of_manifest_file reads as 0, so --setmtime sets the file to 1970. SetMTime skipped the file.

* fix(stash): list stashes by creation time, as fossil's stash ls does

fossil stash ls orders by ctime, oldest first. List ordered by stash id, newest first; it now orders by ctime with the id breaking a tie.

* fix(auth): clear a login's invite expiry with the user, atomically

DeleteUser removed the user and its invite expiry in two statements; a failure between them left the user's expiry behind or the user without it. Both now go in one transaction. A user fossil deleted leaves its invite-expire row behind, so CreateUser clears it in the same transaction as the insert; repo invite sets its own expiry afterwards.

The on-open conversion of Julian config and user mtimes is now best-effort: while another connection holds the write lock, Open skips it and a later open converts the rows, instead of failing. check-in: d810a8118f user: [email protected] tags: main, trunk

Fossil and zit write D cards with exactly three fractional digits. go-libfossil wrote whatever precision the time carried, and the default clock time carries nanoseconds: legal under artifact-format §4.6.4, but zit cannot read a D card with more than three digits (danmestas/zit#244), so zit could not open a repository go-libfossil had committed to.

Checkin and AddTag now truncate the time to the millisecond, whether the caller supplied it or the clock did. Parsed artifacts are untouched: the marshaller still keeps any precision it read, so existing artifacts round-trip byte for byte. check-in: fa1895d56b user: [email protected] tags: main, trunk

zit check-in 3f86ff4261 applies six more errata to the -01 drafts. Copy the three drafts and the five new -01 errata files, re-pin their SHA-256 in the requirements tables, and record the check-in in the README.

The draft text changes add six requirements and reword two:

- AF-4.7.3-2: a named delta's delete markers are filtered out of a delta-of-delta's file set and lookups. - AF-4.7.8-1: an absent and a present empty J value decode alike. - AF-6.2-7: the Z verification state is read from the bytes at n-35 and n-34, not from card lines. - RS-5.3-3: a cancel keeps its card's value on the row it writes. - RS-5.3-6: the event table and propagation treat that value as null. - RS-5.3-7: an artifact's tag cards apply in card order. - RS-6.2-4: a branch root carrying *sym-NAME and -sym-NAME keeps the tag. - SP-6.6-4: a client recognizes a refusal by its leading text.

go-libfossil already behaves this way. Each row has a case, checked against fossil 2.28 where the harness does: 421 requirements, 420 covered, 1 partial (SP-9.5-7, as before).

The repo-state §5.3 step 3 change is filed in zit as a -00 erratum and is not pinned, like the other -00 errata; the -01 draft carries its text. check-in: f61c8174a8 user: [email protected] tags: main, trunk

* fix(manifest): maintain the leaf table incrementally (RS-7.3-3)

The leaf table was recomputed from scratch at the end of every crosslink batch, so a check-in lost its leaf verdict whenever a later batch linked an untagged child to it. repo-state-01 Section 7.3, as corrected, and fossil keep that verdict: a check-in and its plink parents are rechecked only when a branch tag is written to it or propagation updates or deletes its branch row (src/tag.c:195, :100-102), and the checks run when the batch ends (src/leaf.c leaf_do_pending_checks).

The rule now lives in a new internal/leaf package: Check (leaf_check), Rebuild (the explicit full rebuild) and Pending (the deferred schedule). internal/tag schedules a recheck at exactly the branch-row writes; the crosslink sweep, receive linker and repair gate apply a batch's schedule at the gate, each phantom-fill cascade transaction and each commit or tag transaction apply their own before commit, and verify.Rebuild keeps the whole-table recompute. Reparenting schedules nothing, as in fossil, so the reparent case is split into a one-batch case and a per-artifact case.

zit check-in 00e1711e802e corrects the erratum's account of Fossil 2.28: forbid-delta-manifests defaults on only since 2.29, and 2.28 defaults it off. The draft text is unchanged. Re-pin the erratum copy and its SHA-256 in the sync requirements table, and record the check-in in the README. check-in: caa2797892 user: [email protected] tags: main, trunk

* test(conformance): re-pin the -01 drafts with the 2026-10-13 errata

Re-pin the repo-state and sync-protocol drafts to zit check-in 5a1b741b25d8, which applies five more -01 errata: repo-state §5.3, §7.3 and §8.3, sync-protocol §9.4/§9.5 and §10.1. zit now keeps each -01 text under the -00 file name; the copies keep their -01 names and conformance/rfcs/README.md records the zit path and check-in. The new errata are pinned, and the requirement tables are re-read against every changed hunk.

The §7.3 and §8.3 cases that were deviations now pass as written, and new cases cover a date tag's arrival order (§5.3), untagged leaves and a merge parent's recheck (§7.3).

The sync server answers each guard-passing ci-lock with pragma avoid-delta-manifests while forbid-delta-manifests is on, defaulting to on as the draft and fossil 2.29 do (fossil 2.28 defaults it off). The client leaves its transfer unchanged on that pragma. A file or cfile whose content does not match its hash now fails the client's round, in a pull and a clone: the reply rolls back, prefix included, and no further round starts.

The leaf table is still recomputed per crosslink batch, so a parent whose untagged child arrives in a later batch loses the verdict §7.3 keeps; that case is marked as a gap, tracked in #426.

* fix(sync): continue after a uvfile content error; renumber the avoid-delta-manifests row

A uvfile whose content does not match its HASH is a handler-reported content error: warn, commit the prefix and follow ordinary continuation (sync-protocol-01 10.1). The avoid-delta-manifests client row is SP-9.5-7 now that share-links took SP-9.5-5 and SP-9.5-6. Older unreleased changelog entries drop the pending-erratum wording. check-in: 600861484f user: [email protected] tags: main, trunk

.gitignore anchored .agent-config/* to the repository root, so a local tool's trace written under conformance/ was committed with the suite in #264. Remove it and ignore .agent-config directories wherever they are. check-in: fd0add2110 user: [email protected] tags: main, trunk

* feat(sync): add share-links mode for pragma req-links and link

sync-protocol-01 Section 9.5 makes share-links mode OPTIONAL. With SyncOpts.ShareLinks a pulling session sends pragma req-links in its first request, as fossil's --share-links does, unless SyncOpts.ProjectCode names another project. It keeps each pragma link URL ARG MTIME as config link:URL = ARG, defossilized and otherwise verbatim, replacing an existing link only with a strictly newer MTIME. A wrong token count, a URL that is not HTTP(S) or an MTIME that is not a positive decimal drops the link.

Where fossil 2.28 differs the draft is followed: fossil fails fatally on a link URL its parser rejects and reads MTIME with strtoll base 0.

New sync.9.5 client cases run against fossil sync --share-links as well. SP-9.5-4 loses its scope note and is covered; SP-9.5-5 and SP-9.5-6 are new rows for which links a client keeps and when it sends req-links.

Tracked in #425.

* fix(sync): answer a client clone_seqno with bad command; make Clone's phantom pull opt-in

Two deliberate #255 deviations from sync-protocol-01 move to conformance.

SP-5.2-6: the server now answers a client-sent clone_seqno with "error bad command" and processes the cards after it, as Section 5.2 requires for a reply-only card and as fossil's page_xfer does.

SP-8.2-5: Clone now sends nothing after clone_seqno 0 and its cleanup round, so by default it leaves the phantoms a clone produces in place, as fossil(1)'s clone does. The follow-up pull that fetched them is now opt-in through CloneOpts.PullPhantoms, whose doc comment says enabling it departs from Section 8.2.

Both cases leave the sync deviations map. Tracked in #424.

* fix(sync): quote a client clone_seqno as received in bad command; keep DST coverage of the opt-in pull

Tracked in #424. check-in: d3fb5397c8 user: [email protected] tags: main, trunk

rsAPICases copied each case's gap mark but never its deviation mark, so repostate.8.3.ckout-inclusive-whole-name, listed in repostateDeviations by #420, ran as an ordinary pass and the coverage report showed RS-8.3-4 as COVERED.

Copy the deviation mark too, and state that case the way the other deviation cases are written: it holds go-libfossil to the draft's answer (Section 8.3 retries "ckout." under ci, where ckout is a keyword, so it names the working files), checks fossil(1) against its own answer (the ckout tag's check-in), and is skipped as a deviation while go-libfossil follows fossil. RS-8.3-4 now reports DEVIATION until the 8.3 erratum is applied. check-in: e71b5c241f user: [email protected] tags: main, trunk

A received delta found wrong when its basis arrives later in the pass fails sync-protocol-01 Section 7.7's commit check, which now rolls back everything the pass stored, as fossil's page_xfer and client_sync transactions do, instead of undoing the delta by hand and keeping the rest. The phantom-fill cascades and the server's closing leaf and tag repair run inside that transaction. Any other card error still commits the prefix before it (Section 10.1); on the client that prefix now includes the reply's buffered igot phantoms and visibility changes.

db.DB.WithBoundTx binds a DB to one write transaction so code written against *DB, nested WithTx included, joins it as savepoints instead of contending for the write lock from a second connection.

SP-7.7-4 is covered; the new SP-10.1-6 has sync.10.1.integrity-error-prefix. Tracked in #418. check-in: c5f5838169 user: [email protected] tags: main, trunk

* feat(resolve): checkout-inclusive request where ckout names the working files

Checkout.ResolveWorking is fossil's "ci+" request (repo-state-01 8.3): while the checkout has a version, "ckout" answers the working files, reported as WorkingVersion.Working rather than as a pseudo-RID. Every other name goes through the same resolver as Checkout.ResolveVersion, restricted to check-ins as fossil's ci+ is. The draft also makes ckout a keyword in a plain "ci" request; this follows fossil, where only ci+ has it.

New repostate.8.3 cases run the request against fossil test-name-to-id --type ci+, and RS-8.3-4 loses its scope note. Tracked in #419.

Tracked in #412. check-in: 056f36e0bc user: [email protected] tags: main, trunk

* fix(sync): repair leaves and tags for check-ins the cascade links (#414)

A pulled check-in arrives as an announced phantom filled the next round, so the phantom-fill cascade links it. The session's closing sweep then found nothing left to link and skipped the leaf and tag-propagation repair, which gated on the sweep's own count: the check-in had an event row and no leaf row, and its parent stayed a leaf. The server handler had the same gap for a pushed artifact that fills a phantom.

AfterDephantomize and AfterDephantomizeBatch now return how many artifacts they linked. The sync client and the handler add that up over the session and close it with the new CrosslinkAfterCascades, which runs the repair once when the sweep or the cascades linked anything (repo-state-01 Section 7.3, RS-7.3-4), not once per file. The receive linker's cancellation paths gate on the same flag.

The repo-state harness gains a pull load: the first artifacts of a script are held and crosslinked locally, the rest pulled in process from a go-libfossil server holding them all. New cases repostate.7.3.pulled-child and repostate.7.6.pulled-retag, checked against fossil per artifact, each run as a .pull case too.

Tracked in #414.

* fix(manifest): link check-ins with absent files; refuse absent baselines

The crosslink sweep held a check-in back until every file it names was stored. A root check-in, or one on a present parent, whose files never arrived got no event, plink, mlink, leaf or tag rows. fossil links it against phantom files (add_one_mlink, uuid_to_rid(..., 1)), and repo-state-01 Section 4.2 makes an unresolved reference a phantom, not an error. The sweep -- Crosslink, the close of every sync and clone, and verify.Rebuild -- now waits only on a delta manifest's baseline. The receive-time cascade and receive linker still wait for files while blobs are still arriving; the closing sweep bounds that wait.

verify.Rebuild linked a delta manifest whose baseline was absent, with no baseline id. fossil refuses it (fetch_baseline) and files it in orphan under a phantom for the baseline; artifact-format-01 Section 8.3 calls this a soft failure retried when the baseline arrives. Every path now does the same, so a sync requests the baseline and the phantom-fill cascade links the manifest when it lands. Rebuild clears and rederives orphan.

The gap case repostate.4.2.root-absent-file passes and is unmarked; new cases cover a present parent with an absent file and an absent or late baseline, each also through verify.Rebuild where fossil rebuild agrees.

Tracked in #406. check-in: 67fc6ced4b user: [email protected] tags: main, trunk

* test(sync): mark a dangling delta whose basis arrives in the same pass

SP-7.7-4 requires every artifact stored in a pass whose bytes are available in that pass to be checked against its HASH. A delta stored dangling is not rechecked when its basis arrives later in the same reply or request; fossil's commit hook catches it and rolls the round back. Add client, clone and server cases for it, marked as gaps.

Tracked in #412.

* test(sync): note how the server late-basis case must tighten when its gap closes check-in: 8f03734a23 user: [email protected] tags: main, trunk

sync-protocol-01 Section 7.7 verifies a reconstructable non-clone file before storage, and SP-7.7-4 has every newly stored artifact whose bytes are available hashed before commit. The client and a clone stored a delta against a held basis as given, and the server checked only a file delta, so a delta that did not give HASH stayed stored under that name until something expanded it.

The check moves to storeReceived, the one choke point every receive path shares, so the client, the server (file and cfile) and a clone refuse a delta whose result is not HASH, or that does not apply. An unheld basis still leaves the delta stored dangling.

* feat(repo): name the current trunk and a branch's open leaf

Repo.CurrentTrunk resolves the main-branch setting's name the way ResolveVersion does, as fossil does for update outside a checkout and open with no version (repo-state-01 Section 9). Repo.BranchOpenLeaf names the open leaf of a branch with the greatest mtime, or reports the branch not open; fossil's branch info takes whichever open leaf its query meets first, and this follows the draft. checkout.BranchLeaves and the new checkout.BranchOpenLeaf share one open-leaf query.

RS-9-1 and RS-9-4 lose their scope notes and gain cases.

* fix(repo): resolve the current trunk as a check-in, reject an empty branch name

Tracked in the stacked work on repo-state-01 Section 9. check-in: c2795c4f48 user: [email protected] tags: main, trunk

* feat(resolve): resolve checkout-relative names and branch-type requests

Checkout.ResolveVersion resolves current, prev/previous and next relative to the open checkout, after tip and before the other forms, as fossil's symbolic_name_to_rid does; a keyword that names nothing falls through. Repo.ResolveBranchStart is the branch-type request: it resolves a name and walks back to the first check-in of its branch. Section 8.3 walks back from every result; fossil only from tag:NAME and plain names, and this follows the draft.

The repostate.8.3 checkout and branch-type cases run against the new entry points, with new cases for a keyword shadowing a tag, prev at a root, an untyped ckout, root:current and a branch-type hash. Tracked in #386.

* fix(resolve): match check-ins only for branch-type requests, merge via checkout

A branch-type request is rewritten to a check-in request (repo-state-01 Section 8.3), so a technote tagged with the branch name cannot answer it. A checkout with no recorded version resolves the ordinary forms, and merge resolves its version through the open checkout. Tracked in #386.

* fix(resolve): wrap a long test line check-in: cba2d0c823 user: [email protected] tags: main, trunk

artifact-format-01 7.1 (AF-7.1-2) matches policy value strings case-sensitively and exactly and makes an unrecognized value fatal. No surface took a value string, so the row stayed partial.

Repo.SetHashPolicy takes sha1, auto, sha3, sha3-only or shun-sha1, as fossil's hash-policy command does with fossil_strcmp, stores the ordinal, and refuses any other string without touching the stored policy. Auto in a repository that already holds a SHA3 artifact stores sha3 (7.3).

New conformance cases drive every name, wrong-case names, unknown names and the empty name through it, and the AF-7.1-2 scope note is dropped. check-in: feea6a1614 user: [email protected] tags: main, trunk

* fix(manifest): link a check-in atop an absent parent despite absent files

The crosslink deferral held back a check-in until every F-card blob was stored. When the primary parent's manifest is itself absent, no mlink row depends on those files (fossil's add_mlink returns before reading one, and the parent's crosslink derives the transition once it arrives), so the wait could never complete for files the repository will not receive. The libfossil repository holds one such check-in, a fossil-scm commit imported without its history; the sweep lost its event and plink rows that fossil rebuild writes (RS-4.2-2).

missingCheckinRefs now skips the F-cards when the primary parent is unavailable; the baseline is still required. Adds conformance case repostate.4.2.phantom-parent-absent-file and a unit test that also checks the child's mlink is derived once the parent arrives.

Tracked in #398.

* fix(manifest): record the remaining crosslink deferral gaps

Adds gap case repostate.4.2.root-absent-file, a receive-linker ordering test for the child-before-parent path, and notes the narrowed exemption. Tracked in #398 and #406. check-in: 15762adeb6 user: [email protected] tags: main, trunk

* fix(sync): stop the client reply loop at a gimme or igot with no artifact name

fossil's client reads gimme and igot only with blob_is_hname; any other line is an unknown command that ends the reply-card loop, as sync-protocol-01 Section 5.2 requires of a malformed defined card. A server case pins the existing bad-command answer to such a gimme.

sync-protocol-01 Section 7.5 has a pushed igot reclassify what the server holds: public igot makes it public, igot HASH 1 private, the latter from a requester without x too, where it still makes no phantom. This matches page_xfer's content_make_public and content_make_private.

Tracked in #391. check-in: 5004d66398 user: [email protected] tags: main, trunk

* fix(sync): end card processing when a pushed file fails its handler

sync-protocol-01 Section 5.2 has a file or cfile handler failure reset the reply, send the error and stop parsing, as fossil's xfer_accept_file path does. A wrong hash, a bad HASH or DELTASRC and a storage failure now break the card loop; a file delta with a held basis is verified before it is stored (Section 7.5).

Tracked in #390.

Tracked in #390. check-in: c36a69e366 user: [email protected] tags: main, trunk

page_xfer writes the clone batch, its catalog, clone_seqno and push card at the clone card and the req-clusters igots at the pragma, so any later reset discards them (sync-protocol-01 Section 10.1). They were sent after the card loop and survived a bad command or refused push. The clone snapshot cookie is now read ahead of the loop.

Tracked in #389. check-in: 65783dbd3e user: [email protected] tags: main, trunk

sync-protocol-01 Section 9.4 applies both pragmas with no Write test, as fossil's page_xfer does. The leaf sweep before each lock write bounds the lock table. nobody's lock row stores a null login; ci-lock-fail fossilizes LOGIN and names a login-less holder nobody. lock-timeout is read as db_get_int reads it.

* fix(manifest,hash): verify the R card at commit; reject an unrecognized hash-policy

A check-in reads its manifest back and requires the R card to equal the digest recomputed over the resolved tree, byte for byte (artifact-format-01 6.3.4, AF-6.3-5). A hash-policy setting outside the ordinals 0 through 4 is now an error instead of a fall back to the default (7.1, AF-7.1-2).

Tracked in #385.

The server verified the login card first and handled every control card before any data card. A file card ahead of its push card was stored, and cards ahead of a successful login got the login's capabilities. Cards are now handled in one in-order loop, as fossil's page_xfer reads them. A request holding an invalid clone sequence is first walked without side effects, which stands in for fossil's whole-request rollback.

A refused push without an earlier pull now resets and answers "not authorized to write"; a refused pull resets, answers "not authorized to read" and ends card processing (sync-protocol-01 Section 6.6).

An accepted push now asks for the server's phantoms after the card loop, at most 500, skipping what the client asked for, shunned names and private ones outside a private sync, as request_phantoms does. A pushed igot makes a phantom instead of drawing a gimme on the spot.

A clone reply card the client cannot read ends the reply-card loop instead of aborting: the session goes on, the second clone round is still made, and the clone then fails naming the card.

The conformance matchers that accepted "push denied" and "pull denied" are narrowed to the draft's text, and new cases put output ahead of a refusal and cards ahead of the push or login they depend on. check-in: 3beb6eeb15 user: [email protected] tags: main, trunk

* test(conformance): cover artifact K, delta-lookup and delta-size requirements

Single-name lookup in a delta manifest now follows artifact-format-01 8.4 (manifest.LookupFile), Marshal writes the K ticket ID lowercase (4.7.9), and new cases cover 3.1 size limits, 3.4 checksum mismatches and date-only timestamps. AF-6.3-5 and AF-7.1-2 stay uncovered with a reason in their rows.

sync-protocol-01 Section 7.6 (SP-7.6-1): a sender replaces a uvfile whose HASH is a SHA3 name with the error "Fossil version 2.0 or later required." when the peer's recorded VERSION is below 20000. The client gated artifacts this way already but sent unversioned files to such a server regardless.

buildUVFileCards now sends the refusal in place of the card, with or without content, and drops the file from the send list, as fossil's send_unversioned_file does. A deletion tombstone names no hash and is still sent. check-in: 6bde4f3729 user: [email protected] tags: main, trunk

sync-protocol-01 Section 8.6: outside a private sync, a gimme for content held as private is answered with igot HASH 1 when the peer's date is 2020-04-13 or later, and with nothing for an earlier or unknown date. fossil's send_file decides it on remoteDate, which page_xfer reads from a client-version pragma carrying DATE and TIME.

The handler now records the peer's date from client-version and sends the private igot in place of the skipped file. check-in: 13e5e9d229 user: [email protected] tags: main, trunk

Three server refusal paths now follow sync-protocol-01:

- Section 6.6 (erratum s6.6-file-card-after-refused-push): a file or cfile card without an accepted push resets the reply, sends "not authorized to write" and ends card processing, as page_xfer does. The pull's igot inventory still follows. - Section 6.4: a refused login ends card processing at its own position rather than ending the request. Cards before it keep their effect, the end-of-request inventory runs, and the reply carries the closing timestamp comment. - Section 5.3 (erratum s5.3-errors-count): errors N counts errors raised, including those a reset discarded, and skips the bad-command error, the private-content refusal and the SHA3 refusal. check-in: 5f4424320b user: [email protected] tags: main, trunk

sync-protocol-01 Section 5.1 (erratum s5.1-truncated-payload-receiver) makes a file, cfile or uvfile payload that the body ends inside a validation failure of the card's handler, never a stored artifact. The decoder failed the whole message instead, so a server answered HTTP 400 and a client dropped every card of the reply.

The decoder now yields such a card as a BadFileCard carrying the handler's malformed-line text and stops, as it already does for a line it cannot frame. The server answers 200 with that error and keeps the cards before it; the client keeps the prefix it processed. fossil 2.28 stores the bytes present; -01 is followed here. check-in: 648f5d4479 user: [email protected] tags: main, trunk

* fix(tag): derive the check-in event time from direct date tags only (#372)

Section 4.2, step 6 of repo-state-01 makes a date tag applied directly to a check-in set its event time, whatever order the tag and the check-in arrive in. Crosslinking read the date tagxref row whatever its source, so re-crosslinking after a propagating date tag retimed the descendants that inherited it, and a cancel, an unparsable value or 0 left no time or a time of 0, as fossil 2.28 does.

tag.RefreshEventTime now holds the rule, and both tag application and crosslinking call it: a direct, non-cancel date row whose value parses to 0 < r < 5373484.5 sets mtime; anything else restores the D-card time kept in omtime. The date-tag cancel, unparsable and zero cases are no longer deviations, and new before-checkin cases cover the other arrival order.

Re-pin the conformance suite to draft-fossil-artifact-format-01, draft-fossil-repo-state-01 and draft-fossil-sync-protocol-01, copied byte for byte from zit check-in 100351e26c. The delta format has no -01 and stays on -00. The -00 errata are folded into -01 and are no longer pinned; the six -01 errata are pinned for the fossil 2.28 behavior they record. conformance/rfcs/README.md records where each copy came from.

The requirement tables are re-read against -01, and new cases cover the date tag's event time (repo-state §4.2 step 6), the Julian-day grammar, a delta manifest naming a delta, dropped reserved F cards, the trailing-punctuation retry, truncated payloads, errors N, a file card after a refused push, the end of a request after a failed login, and the answer to a gimme for private content.

No library behavior changes. Where -01 departs from fossil 2.28 and go-libfossil follows fossil (a cancelled, unparsable or 0 date tag), the cases are marked as deviations. The non-conformances the re-pin exposes are marked as gaps, tracked in #370, #371, #372, #373, #374 and #375. check-in: e49527edd2 user: [email protected] tags: main, trunk

fossil's trunk page_xfer sets g.perm.Read for a requester with Clone, and the section 7.3 erratum states it for uvgimme. The handler treated only o, i and Admin as Read, so a Clone-only requester got no unversioned files, no xtable-hash inventory and no read-gated configuration.

This is an access change. handler.canRead, CanRead or a Clone held before any login (as page_xfer derives Read ahead of its card loop), now owns every read gate: the unversioned catalog for uv-hash and for a clone, uvigot and uvgimme answers, xtable-hash, and reqconfig. auth.CanRead is unchanged, and pull still needs o. The reqconfig interop test compares a Clone-only requester with fossil 2.28 given Read too, since the 2.28 binary predates the trunk change.

Pull still needs o although fossil trunk's derived Read lets a Clone-only nobody pull; that difference is deliberate. check-in: a67fe49556 user: [email protected] tags: main, trunk
