simio is the third package an embedder links; the opt-in guard now checks it alongside the library and db. check-in: d79a35c16a user: [email protected] tags: main, trunk

feat: ticket writes, ticket reads and timeline-since check-in: e448e2e48d user: [email protected] tags: main, trunk

internal/clearsign keeps the SSH envelope, SSHSIG parsing, namespace, hash and SHA-1 checks, none of which need cryptography, and hands the key parse and signature check to an SSHVerifier that the new public package sshverify registers from init. The library therefore no longer links golang.org/x/crypto/ssh and the ECDSA, P-256, Ed25519 and RSA code it pulls in; html-artifact-publisher's TinyGo engine drops from 1,347,569 to 1,093,647 bytes gzipped (3,777,936 to 3,208,411 raw).

Without the verifier nothing is accepted unchecked: a well-formed SSH signature is ErrSSHVerifierUnavailable, which wraps ErrCannotVerify, so a seed under an SSH horizon-seed-key is refused, the held one is kept, and the sync or rebuild fails naming the package to import. Malformed signatures are still bad. The cli package (and so cmd/libfossil) and examples/tinygo import sshverify; a go list guard keeps x/crypto/ssh out of the root and db closures. check-in: a87790f468 user: [email protected] tags: main, trunk

fix: let Create proceed when the filesystem cannot stat the parent check-in: b7e00e1673 user: [email protected] tags: main, trunk

Create's parent-directory check, added in #457, refused a path whenever os.Stat of its parent failed. Under TinyGo wasm a repository lives in a SQLite VFS and os.Stat is unsupported, so every create failed with "parent directory does not exist: /"; standard Go's js/wasm build hung on the same check. It now refuses only a parent the filesystem confirms is missing or is not a directory, and otherwise lets SQLite's own open report a real failure (tracked in #509). check-in: 2449bcd313 user: [email protected] tags: main, trunk

A sync handler asks what a push brought in. Filtering on timestamps missed an artifact made on a machine whose clock runs behind the given check-in's. TimelineSince now keeps entries whose artifacts were stored after the given one: a later receipt (blob.rcvid, which a phantom fill updates), then a higher rid. Any held artifact hash is accepted; an unknown one is an error.

Repo.TicketAdd and Repo.TicketSet write the ticket-change artifact stock `fossil ticket add` / `fossil ticket set` write (D, J incl. +append, K, U, Z), byte for byte, and crosslink it in the same transaction so the ticket, ticketchng and event rows read back at once. TicketOpts.Comment is stored as the stock ticket forms store a remark: icomment with login, username and mimetype.

Repo.TicketList, Repo.TicketChanges and Repo.TimelineSince expose the reads the html-artifact-publisher engine needs, as JSON-ready values. manifest.Timeline gains Kinds and Since to back TimelineSince.

HZ-5.2-2: the seed label appears on no artifact an origin or its structural clone stores, across re-seeding and writes on both sides; the minted floor survives a restart of the origin. HZ-5.2-9: a seed's missing base filled by a pull, a local check-in and a local tag leaves the seed refused, unlinked and unserved, and the transfer that filled it linked. HZ-6.1-2: path-cone and cursor pragmas beside horizon-name are answered as beside pragma horizon, and act; a named clone with path members sends them and records both. HZ-6.2-17: an event-mtime tie resolves to the lowest full hash for tip and a branch; a full-hash-shaped name no check-in has resolves as a symbolic name, and one a check-in has names that check-in first. check-in: 7a375b6d73 user: [email protected] tags: fix/conformance-subtest-t, main, trunk

test(conformance): hand each case its subtest's t; cancel stale Race runs check-in: 49bf242db8 user: [email protected] tags: main, trunk

check runs each case as a subtest, but the suites passed the case the parent's t, captured in a closure. A fixture that skips or fails, as the fossil-built R-card fixture skips when fossil(1) is absent, then called SkipNow or FailNow on the parent from inside the subtest, which Go fails as "subtest may have called FailNow on a parent test". The Race workflow installs no fossil and failed this way in TestSparseCone. check now hands conforms the subtest's t, and all 150 call sites take it, so a case's skip or failure ends that case alone. TestCheckSkipEndsOnlyTheCase guards the harness.

A Race run takes most of an hour and merges land faster, so a new run on a ref now cancels the older one. check-in: 43df2fd2c2 user: [email protected] tags: fix/conformance-subtest-t, main, trunk

docs: regenerate the SDK reference and check it in CI check-in: 51d3b9cf5f user: [email protected] tags: main, trunk

The gomarkdoc SDK pages had drifted about a thousand lines from the code: make docs-gen-sdk was never part of docs-gen, so nothing regenerated them and the docs check did not compare them. ReadBlob, SetContentCache, ListFilesIn and OriginNamer were missing from the libfossil page.

scripts/gen-sdk-docs.sh now renders them, running gomarkdoc v1.1.0 through go run so CI needs no install, then adds the frontmatter. It honours OUT_DIR, gen-docs.sh calls it, and check-docs-generated.sh compares the result, so a stale SDK page fails CI like any other generated input. make docs-gen-sdk calls the same script. llms.txt and llms-full.txt are regenerated from the refreshed pages. check-in: c12b02189f user: [email protected] tags: main, trunk

perf(manifest): memoize parsed sub-manifests by hash check-in: d82fddda6a user: [email protected] tags: main, trunk

draft-fossil-submanifests-00 §7.4: enumeration results SHOULD be cached keyed by artifact name, so a rebuild parses each distinct sub-manifest once. The tree walk's loader now serves a resolved node from, and keeps it in, a new byte-bounded LRU memo on content.Cache (DerivedSized), keyed by the node's hash and charged its bytes, within a quarter of the cache's budget. The existing 32-entry Derived FIFO is sized for a few parsed check-ins; a tree's working set is every distinct node, which would thrash it and evict those check-ins.

Only a node that resolved is kept, so a phantom is looked up afresh and fails the walk as before. Depth, cycle and node-count bounds stay per walk. The memo is dropped with Derived on Invalidate and Clear, and the Repo's cache is replaced at every write.

Listing a tree that differs from one already read in one leaf now parses its manifest and that leaf; listing every check-in of zit's recorded tree history parses 48 sub-manifests instead of 109. SM-7.4-1 is covered.

feat: list a check-in's files in a cone check-in: e90c972c40 user: [email protected] tags: main, trunk

Repo.ListFilesIn passes the public Cone to the enumeration seam as the range predicate (draft-fossil-sparse-cone-00 §4.1). On a tree manifest the walk skips sub-manifests the cone cannot reach (§4.5), so over a sparse store it succeeds where ListFiles fails on an elided node. It reads through the attached content cache, via a new internal manifest.ListFilesFilteredCached.

ci: run the unit suite under -race; give packages 10m check-in: 612977a2d6 user: [email protected] tags: main, trunk

A Race workflow runs every unit package under the race detector after each merge to main, nightly, and on demand. The full suite passes under -race with no data race reported; it takes several times as long as without, so it does not gate pull requests, which already must be up to date with main to merge. Fossil and zit are not installed there; their interop tests skip, and the Tests workflow runs them.

The unit steps' -timeout is per package binary, and conformance alone takes 130-255s on a hosted runner, so 300s failed it on runner variance. It is now 10m. The dst steps keep 300s. check-in: fdd361b5a9 user: [email protected] tags: main, trunk

fix(sync): export OriginNamer so an embedder's transport keeps a horizon cursor check-in: a52911df25 user: [email protected] tags: main, trunk

Sync and Clone keyed the horizon cursor (draft-fossil-horizon-00 §6.2.6) on an unexported syncOrigin method, which only the HTTP transport could satisfy. Any other Transport kept no cursor and announced its whole holding with igot on every pull.

OriginNamer is an optional interface, discovered by type assertion like FramedTransport, with SyncOrigin() string. The HTTP transport implements it in place of the unexported method, so one assertion serves both. The name must identify the peer stably and carry no credential.

feat: read an artifact by hash and cache content on Repo check-in: 5e882bf1f1 user: [email protected] tags: main, trunk

Repo.ReadBlob expands one artifact by its full hash after the availability check ReadFile applies, and names an unknown hash with ErrArtifactNotFound.

Repo.SetContentCache attaches a byte-bounded content.Cache that ReadFile, ReadFileAt, ReadBlob, ListFiles, Diff and Annotate share; check-in parses are kept in its derived memo, so reads at one check-in parse the manifest once. Default off. A read that finds the DB's finished-write count moved swaps in an empty cache, so a purged, compacted or elided artifact, and a rid SQLite reuses after a purge, is never served from it. Writes by another process are not seen; the method's doc says so.

feat(commit): carry files by UUID; fix Create's default login check-in: d0abc1b3fa user: [email protected] tags: main, trunk

A carried file outside a sparse store's cone skips the held check, so any caller text of 40 bytes or more reached the F card verbatim, including a newline that writes a card of its own into the check-in. checkCarried now refuses a UUID that is not a lowercase SHA1 or SHA3-256 hash, which covers FileToCommit.UUID and the sparse checkout path alike (tracked in #486).

The default login follows fossil's db_create_default_users, which checks FOSSIL_USER before USER, LOGNAME and USERNAME (tracked in #487). leaf check-in: 2237a3781a user: [email protected] tags: feat/carried-uuid-default-login, main, trunk

Create with an empty CreateOpts.User read only $USER and then panicked in db.SeedUser on the empty login whenever that variable was unset, as it is in many containers and CI runners. The default login is now chosen as fossil(1)'s db_initial_setup chooses it: the first of USER, LOGNAME and USERNAME that is set, else "root". check-in: c15a6c60e9 user: [email protected] tags: feat/carried-uuid-default-login, main, trunk

FileToCommit gains a UUID field. When set, the F card names that artifact verbatim and nothing is read or stored, reaching the internal manifest.File.UUID path that sparse checkouts already use. A caller that lists a parent's files can now commit with PartialManifest, dropping files, by naming the unchanged part of the tree instead of re-reading and resubmitting every byte of it. Both UUID and Content on one file is refused; so is a UUID the store does not hold outside an eliding cone. check-in: 37bba3f7b9 user: [email protected] tags: feat/carried-uuid-default-login, main, trunk

fix(horizon): date a seed no earlier than the origin's minted floor check-in: d47958493b user: [email protected] tags: main, trunk

A mint wrote the floor on every structural pull and failed the request when it could not, so a read-only mirror or a store whose write lock was held no longer served the structural horizon. The floor is now written only when D moves later, and a failed write is ignored: the mark is a SHOULD, and without it the next seed is dated from the tag rows as before. A stored value that is not a canonical integer, which an overflowing cast would rank above every D, is replaced. check-in: 8356d3d19e user: [email protected] tags: feat/horizon-seed-floor, trunk

Shunning and purging the latest tag event removed the tagxref rows a seed's D was dated from, so the next seed was earlier than the one every structural clone held. Each clone's D floor refused it as a replay and it fell back to the content horizon until the repository's tags caught up with the purged tag's time; a far-future tag held it there indefinitely.

The draft (zit 39546186f4, §5.2.2) now has an origin date a seed no earlier than the latest D it has minted and keep that D across restarts. Mint reads the mark from the store's horizon-seed-floor config row, dates the seed at the later of it and the latest tag event, and raises the row after minting with a conditional upsert, so concurrent mints never lower it. No config group transfers the row, so it is never sent.

Re-pins draft-fossil-horizon-00 at 39546186f4 and adds the conformance case horizon.5.2.2.seed-date-shun, which fails without the floor. check-in: 1fd0dfdbc1 user: [email protected] tags: feat/horizon-seed-floor, trunk

feat(horizon): re-pin to zit caeef421ee: repository-wide seed D and the receive rule check-in: 7b6f43f1dc user: [email protected] tags: main, trunk

zit 0.7.2 (tag version-0.7.2, check-in 1dcb2d4a29) dates a seed at the repository's latest tag event, as go-libfossil now does. Its horizon draft is the caeef421ee text pinned here (artifact ab18fa7f89).

- ZIT_VERSION is 0.7.2, and ZIT_SHA256 is the checksum of zit-0.7.2-linux-x86_64.tar.gz, checked against the release's SHA256SUMS. - REQUIRE_ZIT_SEED_DATE=1 sits next to REQUIRE_ZIT_BIN, so TestHorizonSeedDateZit cannot skip in CI. - The README, horizons.md, CHANGELOG and test comments now say interop is pinned to zit 0.7.2. check-in: 0c30e0d32e user: [email protected] tags: feat/horizon-dfloor-receive, main, trunk

TestHorizonSeedDateZit has zit mint the seed for a repository whose newest tag event is a cancel, and requires it to match go-libfossil's byte for byte. Both now date a seed at the repository's latest tag event (§5.2.2).

No string in the binary tells a zit from before caeef421ee apart: its version still reads 0.7.1. So the test recognises an older zit by an earlier D in an otherwise identical seed, and skips it unless REQUIRE_ZIT_SEED_DATE=1. CI's pinned zit 0.7.1 skips. A zit built at caeef421ee passes with the variable set. leaf check-in: ad82b4a46d user: [email protected] tags: feat/horizon-dfloor-receive, main, trunk

Re-pins draft-fossil-horizon-00 to zit trunk check-in caeef421ee (file artifact ab18fa7f89), which changes §5.2.2, §5.2.3 and §6.2.3 and adds two Appendix C bullets. This brings in the local feat/seed-receive-drop branch, which implements the receive rule, and resolves it against main (#477 chain-walk bounds, #478 seed binding).

§5.2.2, the seed's D (tracked in #479): - Mint dates a seed at max(tagxref.mtime) over every row in the repository, cancels and propagated rows included, as zit's latestTagEvent does. It was the latest of the rows the seed summarizes. - A cancel of the newest tag, or a reopened closed branch, therefore no longer mints a seed earlier than the one a clone holds, which the clone's D floor refused as a replay.

§5.2.3, the receive rule: - A pull, clone or sync drops a seed by this store's label or by a binding card when it can read it, and the link step refuses one completed later. - The draft also requires that a delta kept without its base, pushed or received, is not announced or served while it cannot be expanded. feat/seed-receive-drop only withheld pushed ones. The pending mark moves into storeDeltaContent, so a pull marks too, and a clone marks what is still unreadable when it ends (seedcheck.WithholdUnreadable). That avoids judging every dangling file delta of a clone a second time. - Since #478 minted seeds carry a binding card. The seed-shaped-ordinary cases therefore strip it, and a new test checks that a seed with the card is never linked.

Conformance rows: - HZ-5.2-2 takes the new D text. - HZ-5.2-4 loses the old ordinary-artifact sentence. - HZ-6.2-6 says the D is fixed by the repository's tag events. - New rows: HZ-5.2-14 (the receive-path drop; PARTIAL, since a seed completed in a later round is kept inert, and was counted when its delta arrived), HZ-5.2-15 (the dropped-hash record) and HZ-5.2-16 (withholding unexpandable deltas). - New cases: two D cases mirroring zit's "horizon seed date" regression, a cancel on C and a cancel at an ancestor below it, and five receive cases. - The deepen-floor case now replays an older seed, since an honest origin no longer mints one. check-in: 5d0ef566aa user: [email protected] tags: feat/horizon-dfloor-receive, main, trunk
