* test: isolate fossil's global config in tests that run the fossil binary (#284)

Tracked in #284.

* test(testutil): document the file-level scope of the fossil home guard (#284)

* test(testutil): allow StartServer in the fossil home guard (#284) check-in: 8d3f18265e user: [email protected] tags: main, trunk

Start fossil server in its own process group through a shared testutil.StartServer helper and SIGKILL the whole group before Wait, so forked per-connection children cannot write into t.TempDir() during cleanup. Tracked in #352. check-in: bb864e6c58 user: [email protected] tags: main, trunk

* fix(tag): apply bgcolor, user and comment tags to event as fossil does (#343)

tag.ApplyTagWithTx now sets event.bgcolor, euser and ecomment from the bgcolor, user and comment tags for every tag type, NULL on a cancel, as tag_insert does. Crosslinking a check-in reads the three values back from tagxref, as manifest_crosslink does, so a tag that arrived while the check-in was a phantom takes effect.

Tracked in #343.

* fix(tag): store empty event override values as NULL (#343) check-in: 66cd641642 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

fossil's client moves its login card from the body into the x-f-l-c cookie once the server's server-version passes xfer_xflc_check (2.27, 2025-07-27 11:05 or later), and fossil's check_login, when a stored password is not 40 characters, tries the signature again against the shared secret that cleartext password derives (sections 6.4, 6.5). The client always logged in in the body, and the server checked only the stored value.

A request marks itself LoginCookieOK once the gate passes; Message.SplitLoginCookie moves its login card out of the body, and the HTTP transports (sync.HTTPTransport and the public NewHTTPTransport through the adapter) send it as the cookie, on every redirect too. The nonce is unchanged: it already covers what follows the login line, which in cookie form is the whole body. Transports that cannot set a cookie send the login in the body as before. The server side of the cookie landed with the server-version exchange.

HandleOpts gains LoginCookie, so an embedder serving HandleSyncWithOpts over its own HTTP handler can pass the cookie through; XferHandler and ServeHTTP read it themselves. check-in: 9d35c01fb3 user: [email protected] tags: main, trunk

fossil's xfer_accept_unversioned_file stores a received file under the HASH its card gave, takes only the mtime when the content is the same and newer (status 2), and stores an omitted payload as NULL with size 0; send_unversioned_file sends nothing for a name it does not hold; and the client seeds uv_tosend from rows whose hash is not NULL (sections 7.3, 8.5.1). Both sides stored a received file under a hash computed by local policy and dropped status 2 and omitted-content cards; the server answered an absent name with a tombstone; the client queued its tombstones.

uv.Receive now owns the acceptance rule, which the server and the client share instead of each re-deriving it from uv.Read, uv.Status and uv.Write. check-in: d33a37fffd user: [email protected] tags: main, trunk

fossil's send_compressed_file sends a cfile as the blob table stores it and pads a payload that does not end in LF; page_xfer sends a version 3 clone's reply as application/x-fossil-uncompressed, sends the unversioned catalog with a clone when uv-sync is on, and refuses a clone with a reset, the push card and "error not authorized to clone". The server recompressed each cfile, never padded, compressed the reply, sent no catalog, appended its refusal to the reply, and restarted a clone whose SEQNO was negative.

CFileCard's StoredBlob, set by the clone path from the blob table, is now what the encoder sends; xfer.Message.Uncompressed tells the HTTP server to send a reply as card text. The catalog goes to a requester with Read, as for uv-hash: fossil lets Clone imply Read there, which this server does not. A negative SEQNO, which section 8.1 exempts from its fatal, now ends the clone with clone_seqno 0, and the unit test that expected a restart expects that. check-in: 6c69fc1231 user: [email protected] tags: main, trunk

fossil's page_xfer refuses a pushed config card from a requester without Admin with a reset, "error not authorized to push configuration" and a break (section 9.3); drops a client's check-in locks on pragma ci-unlock (section 9.4); and answers pragma req-clusters with send_all_clusters, the cluster igots between "# sending-clusters" and "# end-of-clusters" (section 5.3). The server ignored the first two and recorded the third without answering it.

An Admin's config push is refused too, naming that this server does not apply pushed configuration, rather than dropped while the push appears to succeed. ci-unlock is honored for writers only, as ci-lock already is, and the cluster igots go to any requester, as in fossil: they name public artifacts and carry no content. check-in: 85c48f38eb user: [email protected] tags: main, trunk

fossil's page_xfer answers a client-version that carries DATE and TIME with pragma server-version, and both sides record the peer's release; send_file, send_compressed_file and send_unversioned_file then append "error Fossil version 2.0 or later required." in place of SHA3-named content for a peer older than 2.0, with a server treating a client that announced no release as one (sections 7.6, 9.1). The server sent no server-version and neither side kept or gated on the peer's release.

The server gates gimme, clone and uvgimme; the client gates its answer to a gimme. Because a server-version from a current release turns fossil's client to logging in through the x-f-l-c cookie (section 6.5), the HTTP server now reads that cookie: xfer.DecodeRequest puts its login card first with the nonce bound to the whole body, as page_xfer does. Without it a real fossil client's later rounds arrived as nobody. That moves sync.6.5.server-cookie-login, marked for #304, here. check-in: 6963b0a9dc user: [email protected] tags: main, trunk

fossil's client_sync continues a round when stored content or a new phantom leaves the phantom table non-empty, or when files are queued for the next request (section 3.7). The client instead continued on any received file and on any phantom until it had aged three rounds, kept a gimme it could not answer queued forever, and kept an igot's phantom only in the session's map. After a clone's first round it aborted on a server error, where the draft ends the reply-card loop and goes on.

converged now applies 3.7 (a) and (b). A gimme is queued only for content the client holds and may send. An igot's phantom is written to the phantom table, batched once per reply as content_new would write it, and the after-dephantomize cascades of a reply run as one batch (manifest.AfterDephantomizeBatch), so a pull no longer begins a crosslink transaction per artifact. A clone records a later round's server error, stops reading that reply, continues by 3.7, and fails at the end naming the error. Four unit tests that encoded the old continuation now expect fossil's. check-in: 62683d1d0f user: [email protected] tags: main, trunk
