[s3] force filer apply s3 expiry metadata (#10469)
* fix: apply S3 Expiry Metadata * add test Header X-Seaweedfs-Expires-S3 * resolve comments * test entry lookup by mtime * filer: skip s3 expiry stamp on versioned entries The s3 expiry path skips entries carrying a version id, so stamping one takes away its expiry rather than moving it onto mtime. Files under .versions/ are written once, so crtime already tracks their needles. --------- Co-authored-by: Konstantin Lebedev <whitefox@mayflower.work> Co-authored-by: Chris Lu <chris.lu@gmail.com> |

s3: give a versioned metadata-only copy its own chunks (#10594)
* s3: give a versioned metadata-only copy its own chunks A self-copy that only rewrites metadata clones the source entry, chunk fids and all, and writes the clone back. With no versioning that is exactly right: the clone replaces the entry it came from, so one entry owns the needles the whole time. Under versioning the clone lands in a new .versions/ file and the source stays live, and nothing refcounts a plain shared chunk list -- deleting either version (a NoncurrentVersionExpiration rule, say) frees needles the other still points at, and the next vacuum makes that permanent. rclone hits this on every upload, since it stamps mtime with exactly this copy. Take the metadata-only path only where the write replaces the entry it read: the bare key of a bucket without versioning. Versioned, suspended, and versionId-pinned copies fall through to the regular copy path, which gives the destination its own chunks. * s3: reencrypt a versioned SSE-KMS key rotation instead of reusing the chunks A same-object copy that changes the KMS key id hands the source chunks straight back, on the assumption that the copy overwrites the entry they came from. A versioned bucket writes a new version beside the source instead, so the two end up sharing needles that nothing refcounts, and deleting either one frees the other's data. Reuse the chunks only when the destination really is the source entry; otherwise fall through to the reencrypt path, which also gives the new version the key it asked for rather than leaving it on the old one. * s3: make one predicate decide whether a copy replaces its source The metadata-only branch and the key-rotation strategy both answer the same question -- does this copy write back to the entry it read -- so let them share one predicate instead of pairing a same-destination check with it separately at each site. * test(s3): fail the copy regression tests when the vacuum does not run The helper swallowed a failed or non-200 request to the master, so a vacuum that never ran turned both chunk-ownership assertions into no-ops: the tombstoned needles were still readable and the surviving version looked fine either way. Require the endpoint, the request, and a 200. * ci(s3): run every versioning test in the regression gate The gate named the tests it wanted, so a new regression test sat there uncovered until someone remembered this file -- it fooled me into thinking two tests added in this PR never ran anywhere, when the comprehensive job had them all along. Invert it: run everything, and name a test only to keep it out. The delete job beside this one already works that way, and the suite costs about two minutes. Only the pagination stress tests are excluded; they build 1500+ versions, skip themselves without ENABLE_STRESS_TESTS, and have their own make target. Go's regexp has no negation, so the pattern is still assembled from a listing, the way the volume-server integration workflow does it. Note the trailing $$: make eats a lone trailing $ and takes the anchor with it. |

iam: authorize IAM management actions as IAM actions (#10593)
* s3: keep a non-S3 action out of the request-shape resolver
ResolveS3Action reads the request shape before it looks at the base action, so
an iam: or sts: action on a request that happens to carry an S3 query parameter
came back as the S3 action for that parameter. An action that already names its
service is resolved; there is no S3 request shape to read for it.
* iam: authorize the standalone IAM server's actions as IAM, not as S3
The standalone `weed iam` server wrapped its single POST / route in the generic
S3 Auth middleware with ACTION_ADMIN. The route has no {bucket}, so the check
ran with an empty bucket and resolved to a coarse S3 action rather than the IAM
one. The embedded IAM surface checks iam:<Action>; the standalone one was never
updated to match.
Both now go through one authorization function, so they cannot drift apart
again. It also rejects the anonymous identity, which has no user of its own to
run a self-service action against, and reads UserName from the body only, where
the handlers read it from.

s3: retire the suspended null marker only once the PUT has committed (#10589)
The suspended PUT dropped the null delete marker before writing, so a failed write left the .versions pointer naming a marker that was gone. The read path heals a dangling pointer by promoting the newest survivor, so a key the caller had deleted came back serving an older version, and the heal persisted that pointer. Move the retire into afterCreate via the shared finalize, which also brings the ownership check the copy and multipart paths already have. |

s3: report the effective ownership when a bucket has none stored (#10591)
* s3: report the effective ownership when a bucket has none stored GetBucketOwnershipControls read Seaweed-X-Amz-Ownership straight out of the bucket entry, so a bucket that never had one written reported an empty ObjectOwnership. The object write path defaults the same missing attribute to BucketOwnerEnforced, so the API contradicted the behavior it describes. Resolve the stored value through one helper both readers share, and let PutBucketOwnershipControls persist unconditionally so setting the default value still gives DeleteBucketOwnershipControls something to remove. * test: cover the bucket ownership controls round trip Pins the behaviors the ownership default fix depends on: a bucket that never had ownership controls written reports BucketOwnerEnforced, and putting that same value on such a bucket still persists it, so the delete that follows has something to remove. The put-then-delete case gets its own bucket -- run after an ObjectWriter put, it would pass against an implementation that skips only the initial write. The acl workflow already runs this package against a live weed mini, so it needs no wiring. |

s3: let a suspended-versioning multipart completion replace the null delete marker (#10585)
* s3: let a suspended-versioning multipart completion replace the null delete marker In a versioning-suspended bucket a DELETE writes a null delete marker into the key's .versions directory. CompleteMultipartUpload then writes the new null version at the regular path but left that marker in place, so the completion returned 200 and the object listed while HEAD and GET kept resolving the marker and answered NoSuchKey. PutObject already handles this; do the same on the multipart path. * s3: order the suspended-versioning null cleanup behind the multipart write Removing the null delete marker before writing left a failed completion having already published the key's newest real version: the marker was gone, the pointer still named it, so reads rescanned .versions and promoted the older version. Do both fixups only once the write commits, pointer first so reads never see a pointer aimed at a marker that is no longer there, and fail the completion when the pointer cannot be cleared instead of returning 200 for an object HEAD and GET still miss - a non-ErrNone finalize keeps the upload directory, so the caller's retry replays it. Also cover a pre-suspension real version in the regression test. * s3: skip the suspended null cleanup when a concurrent write won the key The completion's .versions fixups are unconditional rewrites of shared state and the routed path runs off the object write lock, so a DELETE landing between the multipart write and the cleanup had its own null delete marker erased - leaving a successfully deleted key readable as an older retained version. Re-read the object first and leave the cleanup alone unless it is still the one we wrote. This narrows the window rather than closing it; a compare-and-set pointer flip is the real answer and wants its own change. * s3: re-read the completed object from the filer that took the write The guard compared the object against our upload id through the routed read, which skips an owner it recently found unreachable and falls back local-first. A write that just landed on the owner could then read as superseded on another filer, skipping the cleanup and leaving the key unreadable - the bug this set out to fix. Read back from the filer the write went to instead. * s3: trim the suspended-completion comments to the non-obvious why * s3: lift the suspended null-write finalize into a named helper The pointer-then-marker ordering is policy shared by every suspended null write, not something the multipart path should be stating on its own; putSuspendedVersioningObject and the copy path each restate it today. Give it a home next to the versioned finalize helpers, and reuse the canonical key normalizer and the existing test helpers rather than open-coding both. * s3: retire the null delete marker on a suspended-versioning copy The suspended CopyObject branch cleared the .versions latest pointer but left the null delete marker a preceding DELETE wrote. While the regular-path object owns the null slot that marker is shadowed, so it reads and lists correctly - but it resurfaces as a phantom delete for a key nobody deleted once that null version goes away. Route the branch through the shared finalize. * s3: keep the suspended null cleanup from erasing a concurrent delete Retiring the marker on the copy path reopened the race the multipart path had already closed: a DELETE landing between the write and the cleanup lost its own marker, so a rescan promoted an older version under a deleted key. Move the ownership check into the shared finalize, keyed on the attribute that identifies the caller's write, so both paths get it. |

s3 lifecycle: bound the daily-replay pass so a quiet cluster stops wedging the job (#10578)
* s3 lifecycle: bound the daily-replay subscription at the pass boundary A pass opens one meta-log subscription and 16 shard drains, then waits on all of them. Nothing told the subscription where the pass ends, so the only exit was the fan-out spotting an event past runNow — i.e. some unrelated write landing under /buckets after the pass started. On a cluster that goes quiet the reader parks in Recv, every shard drain starves on an empty channel, and Run never returns. The job sits at stage "starting" with the executor slot held and no log line, so expiry stops cluster-wide until someone restarts the worker. The pass covers (globalStartTsNs, runNow], so say that: UntilNs on the subscribe request makes the filer end the stream once it has shipped that range. The reader then closes the event channel on the way out, which is what unblocks the fan-out and the drains when the stream finishes on its own rather than by cancellation. Same fix retires the other silent hang: a reader that failed early (subscribe error, stream error) also left every drain waiting forever. * s3 lifecycle: keep a halted shard from starving the shared fan-out A drain that halts mid-stream (BLOCKED / RETRY_LATER / an RPC error on dispatch) returns while the fan-out is still routing that shard's events. After 256 of them the per-shard buffer is full and the fan-out blocks on the send, so no other shard sees another event. Run's WaitGroup never drains, and the teardown that would cancel the reader sits behind that wait — the pass wedges exactly like an idle subscription did, with one S3 hiccup as the trigger. Keep discarding the channel after runShard returns. The events are past this shard's saved cursor and get re-scanned next pass anyway. * s3 lifecycle: assert the starved shard actually made progress The fan-out test only checked that Run returned, which a version that quietly dropped the second shard's events would also satisfy. Assert the dispatch landed and the cursor moved. recordingClient gains a per-object outcome map: the two shards dispatch from separate goroutines, so pinning BLOCKED by call index was a race waiting to pick the wrong shard. * s3 lifecycle: fail the pass when the shared subscription dies Closing the event channel on reader exit is what unblocks the shard drains, but it also means a subscribe that never opened, or a stream that broke mid-pass, now ends every drain cleanly. Run logged that at V(2) and returned the shard result — so a filer failure produced a green lifecycle job that had processed nothing. Surface it as the pass error. Cursors still hold what was processed and tomorrow resumes there; what changes is that the job stops claiming success. Cancellation has to stay a non-error — the shell driver's -runtime cap is a truncated pass, not a failed one — and a canceled gRPC stream arrives as a status code, not a wrapped context.Canceled, so isCanceled checks both forms the way the rest of the tree does. * s3 lifecycle: decide reader cancellation by intent, not status code A stream we cancel and a stream the filer cancels both arrive as codes.Canceled, so classifying the reader's exit by its error let a truncated pass report success whenever the failure happened to carry a cancellation status. Intent is knowable exactly, so read that instead: the pass stops on purpose only when the caller's context ended (the shell driver's -runtime cap) or the fan-out hit the pass boundary itself. Everything else is a broken subscription and fails the pass. TestRun_ServerSideCancelFailsThePass and TestRun_CappedPassIsNotAFailure are the same codes.Canceled from the reader with opposite verdicts — the pair only passes because the decision no longer looks at the error. * s3 lifecycle: time out a subscription that stops delivering UntilNs ends a healthy stream and gRPC keepalive catches a dead connection, but neither reaches a filer that keeps answering pings while its handler has stopped producing. The pass would wait on that forever, since s3_lifecycle is the one job type with no execution timeout. Bound the wait for each response at 20 minutes, and opt into the filer's idle heartbeats so a caught-up stream proves liveness instead of looking stalled. The default sits above the filer's 15-minute metadata-gap recovery budget, so a subscriber legitimately parked on a gap is never mistaken for a stalled one. Recv is only interruptible by killing the RPC, so it moves to its own goroutine behind a per-response deadline. The timer covers only the wait on the filer — dispatch to Events happens outside it, so a slow consumer can't trip the watchdog. Approach and the 20-minute figure are from #10577 by way of comparing the two fixes; the wiring differs because the reader here ends the pass by closing its event channel rather than cancelling the fan-out. * s3 lifecycle: trim the comments added by this branch Keep the non-obvious why, drop the prose restating what the code says. * s3 lifecycle: snapshot reader intent where the reader stops Sampling ctx.Err() during teardown reads it after the drains and cursor saves have run. A reader that failed while the deadline was still live, on a pass whose teardown then outlives that deadline, was classified as an intentional stop and reported success. Sampling earlier in Run is not the fix either: before the shard wait, a legitimately capped pass has not reached its deadline yet and would be misclassified the other way. Intent belongs where the reader actually stops, so the reader goroutine records it next to the error it returns. Reported by greptile on #10578. * s3 lifecycle: cover the worker-dispatched pass with nothing due The e2e suite drives the shell command in 14 of 15 files; the one test on the real admin->worker path backdates an object, so its own delete pushes a meta-log event past the pass boundary and ends the pass. The branch where a pass has nothing to dispatch was never exercised through the worker. Cover it, asserting the pass returns on its own: no admin cancellation, and the executor slot free for the next one. This is not a regression test for the wedge. A pass used to end when any write landed past its boundary, and on a shared test cluster something usually does — the whole suite passes on the unfixed build, verified. The deterministic guards stay the dailyrun unit tests; this one would catch a pass that hangs unconditionally. |

s3: stop treating a directory marker as a versioned object (#10573)
* s3: delete a directory marker instead of versioning it The key "dir/" is stored as the filer directory itself, so a delete marker cannot stand in for it without hiding the children underneath, and its history has to sit inside the directory it describes, where listings keep meeting it. Delete it the way an unversioned bucket already does: remove the directory when nothing is left under it, demote it to a plain directory when children remain, and drop a history an older build recorded for it. * s3: stop resolving directory markers through a version history Nothing records one for them any more, so the lookups that read it are dead weight - and the one in the listing was a filer round trip per directory marker returned, which for a bucket that keeps a marker per directory is the whole listing cost. A listing reads what a directory stands for straight off the entry it already has; a unit test pins that N markers cost one ListEntries rather than N+1. The guard that keeps a history left inside a directory by an older build from surfacing as a key named after it stays. * s3: do not let deleting "dir/" destroy the object at "dir" Writing under an existing object turns that object's entry into a directory while it keeps its data, so the keys "m2" and "m2/" end up sharing one entry. Stripping the entry to delete "m2/" therefore wiped the object at "m2" - a different key, and in a versioned bucket one no delete marker records. Leave a directory holding uploaded data alone; "m2/" does not name it. * s3: make the directory-marker delete fail closed and take the write lock The guard that spares a promoted file only fired when the entry read succeeded, so a transient filer error fell through to the delete and could destroy the object at "dir" anyway. Fail the request instead, take the object write lock so the entry cannot change between the check and the delete, and report a stale history that cannot be removed rather than leaving it to keep naming the key in ListObjectVersions. * s3: check If-Match inside the directory-marker delete lock The lock belongs to the caller: taking it inside the delete nested it under the batch handler's own lock, and since every lock from a gateway shares one owner the inner release would have freed it while the outer caller still assumed it held it. Both callers now own the lock, the single-object path re-checks If-Match inside it the way the other delete paths do, and a batch delete of a trailing-slash key in an unversioned bucket goes through the same marker path instead of the raw delete. A history lookup that fails now fails the delete. |

iceberg: withhold the S3 endpoint from credential-vending clients (#10570)
* iceberg: withhold the S3 endpoint from credential-vending clients A client that sends X-Iceberg-Access-Delegation: vended-credentials builds its storage credential out of the LoadTable config and drops the one it was configured with. We vend no credentials, so the endpoint we advertised left DuckDB signing nothing: every metadata and data file came back 403, and its attempt to refresh the empty credential 404ed on stage-created tables. Answer those clients with no config at all so they keep their own credentials. Clients that do not ask for delegation still get the endpoint. * iceberg: mark load responses as varying on the delegation header The FileIO config in a table or view load response now depends on whether the client asked for vended credentials, so a cache between us and the client must key on that header rather than on the URL alone. * test: cover the DuckDB vended-credentials access pattern Runs weed mini with -s3.externalUrl, which is what makes the catalog advertise an endpoint at all, and checks both halves: a plain LoadTable still gets the endpoint, while one asking for vended credentials never gets an endpoint without the credentials to sign with. The DuckDB round trip creates a table from a query and reads it back, which is the flow that failed with 403 on every data file. |

s3: honor the version history of a directory marker (#10571)
* s3: stop listing a directory marker whose latest version is a delete marker A directory marker is stored as the filer directory itself, so deleting the key "dir/" writes its delete marker into dir/.versions while the directory keeps its mime and stays a key object. Every listing kept reporting the key. Consult that history before treating the entry as a key, and demote it in memory when it is delete-marked so live children still hold the prefix. Also skip the container's own .versions entry while listing inside it: the suffix match read it as the history of a nested object named "", which surfaces as a phantom dir/dir key as soon as a live directory version exists. * s3: a directory marker with version history is not also the latest null version The directory entry behind the key "dir/" is that key's null version, but list-object-versions reported it with IsLatest hardcoded true. After a delete the key came back twice, once as the delete marker and once as a null version, both claiming to be latest. Read the pointer under the directory instead. * s3: resolve directory markers through their version history on GET and HEAD GET and HEAD short-circuit any trailing-slash key straight to the filer directory, so a directory marker kept answering 200 after its delete marker was written. Resolve the key from dir/.versions first when the bucket is versioned: a delete-marked current version answers 404 with x-amz-delete-marker, a named delete-marker version answers 405, and a key with no history keeps today's directory-probe behavior untouched. * s3: re-creating a directory marker retires its delete marker PutObject on a trailing-slash key never looked at the bucket's versioning state, so re-creating a marker after a delete left the latest-version pointer on the delete marker and the key stayed invisible to every versioned read. Point the key back at the directory entry, which is its null version, and drop the null version .versions may still hold — the same two steps a suspended write already takes, now shared. * s3: fail a directory-marker request whose version history cannot be read Every lookup of dir/.versions treated any error as "no history", so a filer hiccup served the directory entry for a key whose current version may be a delete marker, reported a null version as latest over one, and let a PUT report success without retiring the delete marker it was meant to retire. Only a confirmed absence takes the no-history path now. * s3: cancel the directory-marker probe stream instead of abandoning it The probe answers off the first entry and returns, leaving the ListEntries stream open for the life of the parent context. Give it a context of its own. |

s3: honor a bucket owner recorded as an identity (#10567)
* s3: resolve a bucket owner recorded as an identity The admin UI and weed shell record a bucket's owner as an identity name in s3-identity-id and never write the account id the S3 API stores alongside it, so such a bucket looked unowned: its ACL owner fell back to the default admin account, and under the default BucketOwnerEnforced ownership every object uploaded to it was stamped with that account instead of the bucket owner. Resolve the identity to its account when no account id is recorded, in the one place both the bucket metadata and the bucket config derive the owner from. * s3: drop the recorded account when the bucket owner is reassigned Changing the owner of a bucket created through the S3 API left its old account id behind, and that outranks the identity when the owner is resolved, so the new owner never took effect for object ownership or the bucket ACL. |

iceberg: let clients select their table bucket as the catalog warehouse (#10549)
* iceberg: accept bare bucket names and ARNs as the catalog warehouse Only s3://<bucket>/ was recognized. A warehouse spelled as a bare table bucket name or as the s3tables bucket ARN -- the two forms users reach for first, the latter being what AWS S3 Tables itself takes -- was silently dropped, so every call landed on the default "warehouse" bucket and failed with "table bucket warehouse not found". * iceberg: report a missing table bucket as 404, not 500 Pointing a client at a table bucket that does not exist -- which every client with no warehouse set does, since the default bucket "warehouse" rarely exists -- returned InternalServerError with a message naming a bucket the client never asked for. Answer 404 and say how to select one. * admin: show the warehouse in the PyIceberg example The example connected without one, so it always resolved to the default table bucket and every client that copied it failed on the first call. * test: pin bearer auth against a table bucket that exists The subtest called the catalog with no warehouse and accepted 500 as proof that auth had passed, since the default bucket does not exist. A missing table bucket now answers 404, which the test read as an auth failure. Give it a real table bucket so only 200 passes. * test: assert the missing-bucket guidance reaches the client The status and error type were checked but not the message, which is the part of the mapping that tells a user how to select a table bucket. * test: encode the warehouse query value The ARN case pasted raw colons and slashes into the query string. Go's parser tolerates them, so the test passed without modelling how a client actually sends the request. |

s3: register an identity's inline account instead of collapsing it into admin (#10548)
* s3: register an identity's inline account instead of collapsing it into admin Credential stores persist an account inline on the identity and never emit a top-level accounts list, so every user created through the IAM API or the admin UI with an email hit the "non exist account ID" branch and was given the shared admin account. Distinct users then presented the same owner id, so ownership checks could not tell them apart and each passed for the others' buckets. Treat an id missing from the account map as undeclared rather than invalid: register it, keeping an email another account already claimed. Both load paths now resolve the account through one helper. * s3: refresh an undeclared account from the identity that carries it The merge path starts from the live account cache, so an identity upserted with the same account id but a new email or display name kept the cached copy: the new address never reached the email index and the replaced one still resolved. Changing a user's email through the admin UI takes exactly that path. An account registered from an inline block is only described by the identity carrying it, so refresh it and move its email claim. Accounts from a top-level list and the predefined defaults are marked declared and stay authoritative. * s3: let an account reclaim an email once its holder moves away Two identities can carry the same email, and the second to load leaves the lookup with the first. Returning early when the incoming metadata matches the cached account meant the loser never re-ran the claim, so an address freed by the holder's update resolved to nobody until the loser itself changed. Re-index on the unchanged path, which is a no-op while another account still holds the address. |

s3: cover three untested STS paths (#10521)
* s3: test the GetCallerIdentity handler The handler had no test, only XML marshalling, so nothing pinned that a caller presenting session credentials is reported as the assumed role rather than the user who minted the session. * s3: drive AssumeRoleWithWebIdentity over HTTP with a real OIDC token Coverage reached the OIDC path either at the IAMManager service layer or through the Authorization: Bearer shortcut. Nothing exercised the public STS entry point an AWS SDK actually calls, which is where parameter parsing, the IAMManager dispatch and the XML response shape live. * s3: test that every STS route emits an audit entry STS responses go out through WriteXMLResponse, which never calls PostLog, so track() is the only thing that logs them. A route registered outside it would mint credentials with no audit trail and nothing would notice. STS has three routing layers, so a new action is easy to attach to the wrong one. * s3: make the STS tests assert what they claim to cover The audit routing test ran against an uninitialized STS service, so every case answered 503 and a non-404 status was the only evidence the request had reached STS at all - the POST-body case could have been served by the dispatcher's IAM branch and still passed. Back it with a real STS service and assert the STS response namespace, which IAM and S3 responses do not carry. The session policy case checked that the policy travelled in the token rather than that it restricted anything; assert the narrowed bucket is allowed and another bucket is refused. Give the forged-token case the same claim set a valid token gets, so it cannot pass for want of a claim, and cover both rejection paths: a key we do not publish, and a key id absent from the JWKS. |

s3: audit the assumed-role principal and the STS caller (#10519)
* s3: log the requester's principal ARN in the audit entry An STS session authenticates as an opaque session subject, so requester alone gave an operator no way back to the assumed role or the session name. Record the principal ARN next to the identity name and emit it as requester_arn. * s3: record the caller identity in the STS handlers AssumeRole, GetFederationToken and GetCallerIdentity verify the caller themselves and are not wrapped by the auth middleware that records the identity, so every audit entry for minting a session had an empty requester. * s3: resolve the audit principal ARN the way policy evaluation does A JWT-authenticated identity carries no PrincipalArn — the auth layer hands the principal over in a request header — so reading the field directly left requester_arn empty for OIDC callers. buildPrincipalARN is the resolver the policy path already uses: header first, then the identity's own ARN, then a synthesized user ARN for legacy identities that have none. |

s3: keep an admin's role session scoped to the role (#10520)
* s3: keep an admin's role session scoped to the role AssumeRole copied the caller's admin standing into the minted session as the is_admin claim, which short-circuits base policy evaluation. An admin assuming a scoped-down role therefore kept full access and the role's attached policies, explicit denies included, were never evaluated. Only a session the caller assumed for itself carries the claim now — a legacy static admin has no IAM policies for such a session to inherit. * s3: name the caller when it assumes a session for itself An identity that carries no principal ARN left the self-assumed session with an empty role name in its assumed-role ARN. callerPrincipalArn synthesizes the canonical user ARN for that case. |

s3: carry storage class in the cached listing metadata (#10516)
A listing on a versioned bucket is served from metadata cached on the .versions directory entry so the whole listing is a single scan. The cache carried size, mtime, ETag, owner and the delete-marker flag but not the storage class, so newListEntry found none and fell back to STANDARD. The result was that HEAD and the listings disagreed about the same object: HEAD reported the class the object was stored with, while ListObjectsV2 and ListObjectVersions reported STANDARD for every object. Clients that filter or tier on storage class act on the listing. Caches the class alongside the other listing fields, clears it with them, and copies it in the routed RECOMPUTE_LATEST path so both finalize paths agree. |

s3: report a peer that went away as ClientDisconnected, not IncompleteBody (#10511)
* s3: report a peer that went away as ClientDisconnected, not IncompleteBody A streaming PUT whose body ends early is always reported as IncompleteBody (400). That collapses two cases with opposite causes: the peer vanished mid-upload, and the peer sent fewer bytes than it promised while still connected. The first points at the network path, the second at the client, and once merged they cannot be told apart from the logs. Split out ClientDisconnected (499) and select it when the request context shows the peer is gone. The upload itself keeps running on a background context so chunks still finish, which means cancellation races the read error; a missed signal degrades to IncompleteBody exactly as before. * s3: note what request-context cancellation is taken to mean |

s3: allow copying an object onto itself in a versioned bucket (#10497)
* s3: allow copying an object onto itself in a versioned bucket The copy writes a new version instead of overwriting in place, which is how an earlier version is restored. Buckets with versioning off or suspended keep rejecting a self-copy that changes nothing. * s3: cover the suspended-versioning self-copy rejection Suspended versioning overwrites the null version in place, so a self-copy that changes nothing stays rejected. Pin that alongside the never-versioned case. |

s3: keep the list marker exclusive for versioned objects (#10496)
* s3: keep the list marker exclusive for versioned objects A versioned object lives in a "<key>.versions" directory, so the entry name never matched the marker and start-after/marker returned the marker key itself. * s3: match the list marker against the raw entry name too A backend that echoes the marker it was given returns the ".versions" directory name, which no longer matched once the comparison used the object name alone. Cover both, and unit test each half. |

s3: register the advertised ip with the master (#10482)
* s3: register the advertised ip with the master The cluster address came from the bind ip, falling back to the auto-detected interface, so -ip never reached the S3 registration. weed mini -ip=localhost binds the wildcard and ended up registering whatever interface happened to sort first -- on a host with VPN interfaces, an address that stops routing once the tunnel drops. IAM changes are pushed to registered S3 servers over gRPC, so every mutation then blocked the full 10s propagation deadline before logging a failure, and cluster.ps and the admin UI listed a node nothing could reach. Identities still arrived through the /etc/iam metadata subscription, so this cost latency and visibility, not credentials. Add an advertise ip to the gateway option, preferring it over the bind address, and wire the parent -ip through server, filer and mini. * s3: treat any unspecified bind address as a wildcard net.ParseIP + IsUnspecified covers ::, [::] and the expanded IPv6 forms instead of only the 0.0.0.0 literal, so an IPv6 wildcard bind no longer registers an address peers cannot dial. Host names parse as nil and stay addresses in their own right. Apply the same guard to the advertised ip. |

s3api: load document-style policies from the advanced IAM config (#10481)
* s3api: load document-style policies from the advanced IAM config The advanced IAM file doubles as the S3 identity config when only -s3.iam.config is given. protojson drops its "document" field, so every policy landed with empty content and warned "skipping invalid policy" on each reload. Worse, if the same file also declares identities the empty content sticks in the policy map and fails the whole runtime policy sync into the IAM manager, so policies created later never reach it. * iam: skip an unparsable policy instead of failing the whole runtime sync One policy the engine cannot parse aborted SyncRuntimePolicies before it touched anything, so every other policy stayed unsynced and the engine kept serving whatever it last held. * s3api: reject a non-role RoleArn in AssumeRole as a bad request arn:aws:iam:::user/name can never resolve to a role, but the handler ran it through the trust-policy check and answered "not authorized to assume role", pointing the caller at a permission problem they do not have. * s3api: build the policy content before touching the entry Deleting "document" up front meant a marshal failure left the policy with neither field, so a later rewrite would emit it with no definition at all. * iam: pin the fail-closed handling of an unparsable policy Say in the comment that dropping it from the desired set deletes it from the engine on purpose, and cover it with a test. * s3api: widen the non-role RoleArn test to canonical ARN shapes The reported ARN omits the account id; a user ARN that carries one, and a non-principal ARN, must be rejected the same way. |

iceberg: read manifest lists that omit the Avro format version (#10475)
* s3tables: read Iceberg manifest lists that omit the Avro format version The Iceberg spec pins the Avro header metadata of manifest files but says nothing about manifest lists, so writers disagree. Java and PyIceberg record "format-version"; DuckDB writes no header metadata at all. iceberg-go reads a missing entry as v1, so every v2 manifest listed in a DuckDB-written list is rejected with manifest file's 'format-version' metadata indicates version 2, but entry from manifest list indicates version 1 and, because v1 has no "content" field, delete manifests silently decode as data manifests. ReadManifestList derives the version from the record schema the writer embedded - v2 added "content" and the sequence numbers, v3 added "first_row_id" - and splices it into the header before handing the bytes to iceberg-go. Lists that already carry the entry, and input that is not a parseable Avro container, go through untouched. * iceberg: parse DuckDB-written manifest lists in maintenance and data preview Every manifest list read - the four maintenance operations and the admin table data preview - went straight to iceberg-go, so tables written by DuckDB failed detection and all of compact, remove_orphans, rewrite_manifests and expire_snapshots before they touched anything. Route them through s3tables.ReadManifestList, which recovers the format version the writer left out of the Avro header. This also restores the manifest content type on those tables: with the list read as v1 every delete manifest looked like a data manifest, which hid deletes from the compaction guard and made the preview report a table with position deletes as having none. |

s3api/iceberg: report the reason a table schema was rejected (#10473)
* s3api/iceberg: report the reason a table schema was rejected newTableMetadata swallowed the iceberg-go error and returned nil, so every schema the metadata builder refused came back as a bare 500 "Failed to build table metadata". A v3-only column type is the common case: creating a table with a variant field but no format-version 3 property leaves the client with nothing, while "variant is not supported until v3" sits in the server log. Return the error instead and classify it. Schema, spec and argument failures are the caller's input, so they answer 400 with the underlying reason; the rest stay 500. Paths that build placeholder metadata with no schema keep their existing 500 via newEmptyTableMetadata. * s3api/iceberg: fail LoadTable when placeholder metadata cannot be built buildLoadTableResult dropped a nil from the placeholder path straight into the response. That serializes as "metadata":null under HTTP 200, which no Iceberg client can parse -- a worse outcome than the 500 the nil was meant to signal. Return an error instead and let the five callers answer 500. The nil-return convention goes away with it, so the commit and transaction paths check an error rather than a sentinel. * s3api/iceberg: route rejected schemas through writeManagerError The two helpers added here duplicated work the package already does. writeManagerError is the canonical error-to-response mapper -- it already downgrades client-input failures to 400 and defaults the rest to 500 -- so teach it the iceberg-go schema and spec sentinels instead of standing up a parallel classifier. The placeholder wrapper was a pure alias for newTableMetadata with nil arguments; call that directly. No behavior change beyond the 500 message, which now reads err.Error() like every other manager error rather than carrying its own prefix. |

s3: list the buckets an attached IAM policy grants (#10458)
* s3: list the buckets an attached IAM policy grants ListBuckets served an identity authorized by an attached IAM policy only the buckets it had created itself. A user granted s3:ListBucket on a bucket someone else provisioned could GetObject and ListObjectsV2 against it, but the bucket never showed up in the listing any S3 client uses to build its bucket picker. The owner-index fast path is only valid for an identity whose grants name every bucket it can reach, and the routing check assumed a policy could never be enumerated. Read the names out of the policy instead: statements that allow s3:ListBucket on a concrete bucket ARN become candidates, and the per-bucket permission re-check still decides what is listed. A policy that can reach a bucket it does not name -- a wildcard resource, a policy variable, a NotResource, an STS session policy -- falls back to the full scan, which evaluates the policy per bucket. * s3: share the attached policy name lookup authorizeWithIAM and the ListBuckets enumeration both built an identity's policy names the same way, its own plus the ones from its enabled groups. Pull that into one helper so group eligibility is decided in a single place. * s3: read policy actions the way the IAM authorizer matches them The IAM authorizer matches action names case-insensitively, so a policy granting "S3:LISTBUCKET" or "S3:*" authorizes a list. The ListBuckets classifier read those actions with the local case-sensitive matcher and found no grant, so once the owner index was ready the buckets that policy allows dropped out of the listing. Match the action the looser way in the classifier: case-insensitive, and true for any pattern holding a policy variable. Over-matching only costs a candidate the per-bucket permission check then rejects, while under-matching hides a bucket the caller can read. * s3: infer a multipart grant in any case The classifier matches action patterns case-insensitively but looked the requested action up in a canonical-cased set, so "S3:UPLOADPART" missed the s3:PutObject inference that the authorizer makes. Key the set for lookup in lower case, matching how the IAM authorizer holds it. |

s3: apply filer identity changes despite a static config file (#10392)
* s3: apply filer identity changes despite a static config file A -config file with inline identities disabled the metadata-subscription reload entirely, leaving the best-effort filer->s3 push as the only way s3.configure changes could reach a running gateway. Reload on IAM events regardless: the merge keeps the file's identities protected, and a full credential-manager snapshot now also drops dynamic identities the store no longer has, so revocation works without a restart. * s3: log identity propagation failures as warnings * s3: retry failed IAM reloads and reconcile policies and groups An event-driven reload that fails now hands off to a coalescing retry loop, so a transient filer error cannot strand a revoked credential until the next IAM event. Full-state merges also drop dynamic policies the store no longer has, keeping the static file's, and treat the group snapshot as authoritative even when empty. * s3: serialize IAM configuration loads The SIGHUP file reload, subscription reloads, the retry loop, and the postgres poll run on different goroutines. Without an end-to-end lock a load holding an older store snapshot can commit after a newer one and revert it. Hold reloadMu from snapshot through commit in both load entry points; partial merges from pushed updates stay lock-free and self-heal through the next event-driven reload. * s3: keep static-file groups through full-state reconciliation Group names from the static config file are tracked like identities and policies, and a full snapshot that does not carry them keeps the current definition and its memberships instead of dropping them. * credential: include groups in postgres configuration snapshots Full-state reconciliation treats absent groups as deleted, so a snapshot that never carries them would erase every dynamic group. * s3: revoke static-file groups dropped from the config file A file reload is authoritative for the file's group set while keeping dynamic groups, mirroring how full snapshots are authoritative for dynamic groups while keeping the file's. * credential: fail filer snapshots on unreadable entries A skipped identity or policy file made the load report success with an incomplete snapshot, which reconciliation reads as deletion and the retry loop never sees. Unparseable content is still skipped: it is durable, matches boot behavior, and must not block reloads forever. * s3: ignore groups in static config files Groups are managed through the IAM API and the dynamic store; no deployment defines them in a bootstrap config file. Ignoring them with a warning removes the two-directional group merge: full snapshots are plainly authoritative and file reloads never touch groups. |

s3: require a bucket-policy action to write a bucket policy (#10444)
* s3: require a bucket-policy action to write a bucket policy PutBucketPolicy and DeleteBucketPolicy were gated on ACTION_WRITE, the same action that grants object writes. An explicit Allow in a bucket policy short-circuits IAM entirely -- authRequestWithAuthType sets policyAllows and skips VerifyActionPermission -- so anyone who could write an object could author a policy granting itself, or anonymous, anything on the bucket. That is what separates a bucket policy from the sibling bucket controls also gated on ACTION_WRITE: rewriting cors or lifecycle can destroy data, but only a policy hands out access. Give the two verbs their own actions, mapped to the AWS names that were already defined but unrouted. ACTION_ADMIN would also have closed it, but it resolves to s3:* for IAM identities, forcing a blanket grant on a user holding a precise s3:PutBucketPolicy. Admins are unaffected, since isAdmin short-circuits CanDo, and an operator can delegate with PutBucketPolicy:bucket. The route binding is asserted from the router source: checking the action constants alone still passes when the route says ACTION_WRITE. * s3: also read the action from a direct iam.Auth call in the route test Routes read iam.Auth(cb.Limit(handler, ACTION)), a multi-value pass-through: Limit returns (http.HandlerFunc, Action) and those become Auth's parameters, so the action Auth authorizes on is Limit's second argument and the two cannot disagree -- Auth(Limit(h, X), Y) does not compile. A route that skipped Limit and called Auth with its own action would compile, though, and the test reported that as a missing route rather than as the wrong action. Recognise the two-argument Auth form so it names the action instead. * s3: make the bucket-policy actions grantable through an IAM policy The new actions close the escalation only if an operator can grant them, and they were not reachable: MapToStatementAction had no entry for PutBucketPolicy, so an IAM policy naming s3:PutBucketPolicy was rejected outright with "not a valid action". GetBucketPolicy was unmapped the same way. DeleteBucketPolicy was mapped, but to ACTION_ADMIN -- granting an identity permission to delete a bucket policy handed it full administrative access. Map all three to the actions the router now uses, and add the reverse direction so an identity holding them renders back as a policy statement instead of a bare "s3:". * admin: offer the bucket-policy permissions in the user editor The two new actions are otherwise only grantable by hand-editing identity JSON or by calling the IAM API, so an operator using the UI cannot delegate bucket policy management without granting Admin. Regenerating this file also picks up codegen the repo has not taken yet: the checked-in _templ.go files were produced by templ v0.3.1001 while go.mod pins v0.3.1020, so the generator rewrites the attribute-value calls. That churn is confined to this one file; running `make generate` in weed/admin reproduces it across all 36. |

s3: chunk uploads at the filer's maxMB (#10439)
The S3 write path cut fixed 8MB chunks, so an object stored through S3 chunked differently from the same bytes stored through the filer, WebDAV or a mount, and -maxMB had no effect on it. Read maxMB from the filer configuration at startup and use it, falling back to 8MB when the filer reports none. |

s3: stop listing prefixes whose objects are all delete-marked (#10419)
Deleting the only object under a prefix in a versioned bucket writes a delete marker and keeps the version history, so the filer directory survives with nothing a current-version listing would return. A delimited ListObjects kept reporting that path in CommonPrefixes, because the prefixes come from the directory tree rather than from the keys, while a listing scoped inside the prefix correctly came back empty. Probe a directory before reporting it: one that holds entries but no key the listing returns is neither a CommonPrefix nor a path the trailing-slash probe answers for. Empty directories keep the meaning they have today, and the probe only runs for buckets with versioning configured, the only ones that can reach this state. |

iceberg maintenance: resolve table files from the recorded location (#10418)
The worker assumed every file of a table sits under its catalog path, so loadFileByIcebergPath stripped the scheme off a recorded location and joined the remainder onto /buckets/<bucket>/<ns>/<table>. A table the REST catalog placed elsewhere in the bucket — which is what a client gets whenever the catalog path is already occupied — then resolves to a doubled path: lookup /buckets/lake/source/t/lake/source/t-0cd81bca-.../metadata/snap-.avro so the very first manifest list read fails and the job fails again on every scan interval, indefinitely. Resolve absolute references (s3:// URIs and /buckets paths) from the bucket root and keep relative ones under the table's own directory; the bucket-relative form is now the canonical key everywhere references are compared. That directory comes from the metadata location the catalog stores, so reads, writes and deletes all land where the table's other files are instead of splitting it across two trees. References outside the table's bucket are rejected rather than silently misresolved. Rewritten position-delete files now name their data file by absolute URI, the way the table itself names it, instead of a path relative to the table. |

mount: version open file handles by filer log position (#10403)
* filer: stamp a log position on lookup and remote-cache responses Metadata events are logged after their store write and stamped with the filer clock. Reading that clock before serving an entry therefore gives a timestamp with a causal guarantee: every event at or below it is reflected in the returned entry. Clients caching filer state can use it as the entry's version to order the response against subscription events, including events committed before the call but delivered after it. * mount: version open file handles by filer log position A subscription event refreshing an open handle did a second lookup; a transient failure left the handle pinned to its old entry with no retry, since the subscription cursor had already advanced. The deeper problem is ordering: the handle is a cache written by three unordered channels — the async invalidation worker, local mutation acks, and open-time lookups — and overwriting cached state safely requires knowing which write is newer. The filer log timestamp is that order, and it now travels with every value instead of being derived out of band. Events carry it natively; lookup and remote-cache responses carry the log position stamped before the serving read; mutation acks carry it in their returned event; and the local store pairs each read with a version cursor advanced under the same lock as the store write. Each handle records the version its entry reflects, and one rule replaces the per-site reasoning: state at or below the handle's version is old news and must not be installed. The invalidation itself applies the event's own entry — no lookup, so no transient-failure window — except under a cached parent, where the store entry is the ordered merge of the event and anything applied since, and its version outranks the event's. An uncached parent receives no store writes, so a hit there would be a stale leftover masking the event. A vacated path (delete, rename away) keeps the last entry so unlinked-but-open reads still work. Directory builds version the completed directory at the listing snapshot and re-invalidate buffered events at that version, since their mid-build refresh ran against an incomplete store. The tests replay every race this replaces machinery for: rollback of a newer local flush (queued, cached, and read-through), stale leftovers under uncached parents, the build window including abort, handles opened after an event was queued, events landing mid-lookup, and undelivered events at remote-cache time across a filer failover. * filer: serialize the log position fence with mutations, stamp mutation acks The fence stamped before an unlocked entry read could precede state the read returned: a mutation writes storage first and assigns its event timestamp only at notify time, so a lookup racing that window handed the mount an entry newer than its fence, and the event's later delivery looked like fresh news — destroying dirty pages for a change the handle already had. The mutation handlers already hold an exclusive per-path lock across read, write, and notify; the lookup and remote-cache reads now take it shared around the stamp and the read, making the fence exact: everything at or below it is in the entry, nothing above it is. A no-change update returns success without an event, leaving the mount nothing to fence with even though the response confirms current state. Create and update acks now carry a log position stamped under the same lock, and the mount falls back to it whenever the ack has no event. Also regenerate the VT marshalers, which the earlier generation missed: without them a VT round-trip silently zeroed every log position. * java: sync filer.proto * mount: scope store versions to what they vouch for; atomic handle install The store's version cursor claimed too much. Advanced by local mutation acks and directory listing snapshots, it inflated the version of store reads for unrelated paths whose events the subscription still owed, and those events were then fenced out permanently. The cursor now tracks subscription progress only — events arrive in log order, so everything at or below it has been delivered for every path — and a completed listing records its snapshot as a per-directory floor instead of a global claim. Local acks never touch it: they version their own handle directly. Buffered build events advance the cursor at delivery, since their store write may never happen (abort) while their invalidation is already queued; their read-through directory pairs no store read with it, and rename fragments are applied first. Concurrent first opens raced: a slower opener's older lookup could overwrite the newer entry a faster opener had installed, while the monotonic version kept the newer timestamp — an old entry fenced at a new version, immune to every correcting event. Entry and version are now installed as one decision under the handle map lock, and an install that does not outrank the handle's version is dropped. The remote-cache commit also escaped the fence: it wrote storage and notified without the path lock, so a lookup's shared-locked fence and read could land between the two and hand out the cached state under-versioned. The commit now re-reads and writes under the exclusive path lock, and backs off entirely when the entry changed during the download — the concurrent writer supersedes the cached content. * mount: floors gate store applies; installs respect handle users; renames join the fence A directory floor certifies the listing state as of its snapshot, but a delayed event at or below the floor was still applied to the store — rolling the content back to pre-snapshot state while the floor kept claiming the snapshot version, so the correcting events were fenced out of every future read. Events are now gated against the affected directory's floor, each half of a rename independently. Fences are lower bounds: a listing or lookup can include a mutation whose event has not been delivered yet, and that event later passes every gate carrying state the handle already holds. Such a re-delivery now advances the version without destroying dirty pages or reinstalling the entry — invalidating local writes over a no-op was the real damage in every remaining under-fence window, including the unlocked listing snapshot, which no per-path lock can serialize. The concurrent-open install moved from the map lock to the handle lock every reader, writer, and invalidation synchronizes on, and rejects what cannot improve the handle: dirty state (local writes would be lost), unversioned lookup responses (they cannot outrank anything, and two zero-version opens must not overwrite each other), and anything not strictly newer. New handles are still fully initialized before the map exposes them. Renames committed metadata and emitted events with no path lock, so a lookup could read the renamed state under a fence preceding its events. Both rename handlers now hold the source and destination locks, ordered by path, across commit and notification; descendants of a renamed directory are not individually locked and rely on the no-op re-delivery handling above. * mount: per-entry store versions replace the cursor and directory floors The store's aggregate versions — a global subscription cursor and per-directory listing floors — were versions at coarser granularity than the values they described, and every over-claiming bug in this series traced to that gap: an aggregate vouching for state its source never saw. Each store entry now carries the filer log position of the write that produced it — the event that applied it, or the listing snapshot that inserted it, recorded in the store's key-value space under the same lock as the entry write. The store becomes what the handle already is: a last-writer-wins register with one rule, install only what outranks the current claim. The cursor, the floors, their advancement rules, the pairing ordering constraint, and the floor gating all collapse into that rule. Applies are gated per entry, each half of a rename independently; an unversioned local write clears the claim its content no longer proves; version records lingering after a bulk folder wipe cannot fence a recreate, since a claim only blocks while its entry exists. Listing inserts are stamped at build completion, before the buffered replay so newer replayed events override the stamp. Filer side, the fence dance every versioned read must perform is now a single choke point, fencedFindEntry, so a future read RPC gets the lock-serialized stamp by construction rather than by convention. * mount: judge no-op re-deliveries against an immutable base, not the live entry The equal-state skip compared the incoming event to the live handle entry, but local writes mutate the live entry — size, timestamps, chunks — so a delayed event re-delivering the base the handle was opened with no longer matched, and the installer destroyed the dirty pages and rolled the entry back over nothing new. The handle now keeps an immutable snapshot of the filer state it last installed or acknowledged, refreshed at every install and mutation ack (flush acks snapshot the request entry before the id mapping mutates it), and the no-op judgment runs against that base: an event carrying the base brings nothing, whatever the live entry has diverged to since. * mount: tombstones for versioned deletes, absence floors, copy enrollment Four gaps in the per-entry version protocol, all the same shape: a versioned fact with nothing carrying its version. A deletion is a fact about a path with no entry left to hold it — clearing the record let a delayed older event resurrect the deleted path, permanently, since the deletion's own redelivery is dedup-suppressed. Versioned deletes now leave a tombstone record that fences without an entry; renames tombstone their source the same way. Plain records still only block while their entry exists, so records lingering after a bulk folder wipe cannot fence a recreate. A completed listing proves absences as well as presences: a name it omitted was deleted as of the snapshot, and a delayed create below the snapshot re-creates it. The snapshot is kept per directory strictly as an absence fence, consulted only when a path has neither an entry nor a version record — present entries carry their own versions and never touch it, which is what separates this from the over-claiming floor it replaces. A rebuild against a pre-upgrade filer returns no snapshot; stamping now clears the children's records in that case, so a reinserted entry cannot reactivate the stale claim its previous incarnation left behind and reject valid events below it. Server-side copies installed the copied entry without enrolling in the base protocol, so the copy's own event differed from the stale pre-copy base and destroyed writes made to the destination after the copy. The install now refreshes the base and takes its version from the fenced readback. * mount: deletion facts outlive the cache's knowledge of the entry A versioned delete of a path the store held no entry for recorded nothing, so a delayed older event recreated the path — permanently, with the deletion's redelivery dedup-suppressed. The tombstone is now written whenever a versioned event vacates a path: the deletion is a fact about the path, not about what this cache happened to hold. For an absent entry, the listing's absence floor now speaks whatever older record remains: a tombstone at one position does not exhaust what is known about the path when a newer snapshot has confirmed the name still absent, and an event between the two was slipping past both. A committed copy whose readback failed installed a synthesized base with local timestamps; the copy's real event legitimately differs from it, and was read as foreign state — destroying writes made to the destination after the copy. The handle now marks that its own event is en route and adopts that event's state as the base without touching the live entry or the dirty pages; the adoption is one-shot, so a genuinely foreign event still invalidates. * mount: authoritative acks cancel pending event adoption; tombstones scoped and pruned The copy-event adoption flag could outlive its purpose: a flush after the failed readback installs a newer base and advances the version, the copy's own event is then version gated without consuming the flag, and the next genuinely foreign event was silently adopted — base advanced, live entry and dirty pages untouched — leaving the mount to later overwrite that remote change. Every local acknowledgment now installs its base through one helper that also cancels any pending adoption: the ack supersedes the mutation the adoption was waiting for. Tombstones were written for every versioned delete under the mount and survived directory eviction by design, growing LevelDB with historical deletions on delete-heavy mounts. They are now scoped to directories whose cached state the fence actually protects — an uncached parent never serves from the store nor applies the resurrecting insert — and a completed listing prunes the direct-child tombstones its absence floor supersedes, leaving only those above the snapshot. The store gains a key-prefix visitor for the sweep. * mount: acked saves install their value; trailer snapshots; direct-child prune range A version must never advance without its value. saveEntry stamped any open handle with the acknowledgment's version, but a handle opened while the save was in flight holds the pre-mutation entry — stamping it fenced out the events carrying the state it lacked, permanently, with the local apply performing no invalidation and the redelivery deduplicated. The acknowledged entry is now installed together with its version, through the same guarded install the racing-open path uses: under the handle lock, only when it outranks the handle, never over dirty local writes. Empty listings return no in-band snapshot — a snapshot-only response would be read as an entry by older consumers — so directories that end empty gained no absence floor and their tombstones were never pruned. The filer now sends the snapshot in the stream trailer, which older clients ignore, and the client reads it when no in-band snapshot arrived. Empty directories get real floors, their tombstones prune, and their buffered replays gain the snapshot filter instead of the replay-all fallback. Version records now encode the parent directory and name separated by a NUL, making a directory's direct children one contiguous key range: the tombstone prune scans exactly them under the cache lock, instead of walking every descendant record — the whole store, for root. * mount: fix dirty-page loss, uid/gid base, download race, copy adopt, leak; dedup Correctness fixes from the versioned-invalidation review: - A foreign delete/rename-away of a file held open with unflushed local writes destroyed the dirty pages unconditionally. A process may keep writing to an unlinked-but-open file and those writes were already acknowledged; preserve the pages when the handle is dirty. - downloadRemoteEntry stored the handle's base with filer-side uid/gid while every candidate it is later compared against is in local form, so under a non-identity UidGidMapper an unchanged re-delivery looked foreign and force-destroyed dirty pages. Map the base to local. - downloadRemoteEntry wrote the entry/base/version triple under only the handle's shared lock, so two concurrent reads of the same remote-only file could tear it. Serialize the install with a dedicated mutex (invalidation is already excluded by the exclusive handle lock). - A committed server-side copy whose readback failed adopted the FIRST event past the version gate as its base; a foreign write delivered first was silently swallowed. Adopt only an event whose content matches the synthesized base — the copy's own event — and install any other normally. - The deferred-create path relied on AcquireFileHandle installing the passed entry on a pre-existing handle, which the version rework dropped. Restore that install in the compat wrapper; the versioned open path keeps its gated install. Growth and hot-path cost: - Per-entry version records and tombstones leaked when a directory was evicted or read-through without a rebuild. An uncached directory gates its own inserts, so its records fence nothing; clear a directory's child version records when it is wiped for eviction. - FindEntry paid for the version KvGet on every lookup/getattr cache hit and threw it away. FindEntry now reads only the entry; the hot lookupEntry cache-hit path skips the version entirely. Cleanups: - Extract ackVersionTsNs over the shared response interface, replacing the metadata-event-else-log-ts snippet copy-pasted at four ack sites. - Extract acquireRenamePathLocks, replacing the verbatim sorted two-path lock fence in both rename handlers. * mount: no resurrection on foreign delete, version no-event acks, gate downloads, tighten copy adopt Follow-ups to the review patches: - Preserving dirty pages on a foreign delete let the next flush pass the isDeleted guard and CreateEntry, resurrecting the remotely-unlinked name. Mark the handle deleted in the vacate branch: the open fd can still read its buffered writes, but a flush no longer recreates the file. - A no-event acknowledgment (log fence only) synthesized a metadata event with TsNs 0, so the cache stored the entry unversioned and an older subscriber event rolled it back. Stamp the synthesized event with the ack's log position at all four ack sites. - downloadRemoteEntry serialized its install but did not check the version, so an older response arriving last overwrote the entry/base while the monotonic version kept the newer value, fencing corrections out. Install only when the response is at least as new as the handle. - sameEntryContent compared only size and chunks, so a foreign chmod with unchanged content was adopted as the copy's own event. Compare everything except server-assigned timestamps, so a metadata-only foreign change installs instead. * mount: trim comments to the non-obvious why The versioning work accumulated multi-line comment blocks restating what the code says. Keep the constraint a reader cannot derive — why a fence is exact, why a version must not advance without its value, why an uncached parent's records fence nothing — and drop the rest. * mount: distinguish rename from delete, tighten the download and adopt gates - A rename emits a nil old-path invalidation just like an unlink, so the vacate branch marked the handle deleted and later writes through the already-open descriptor were skipped instead of persisted. Carry the delete/rename distinction on the invalidation and mark only an actual delete. - The remote-download install accepted an unversioned response regardless of the handle's version, so during a rolling upgrade a delayed response could install stale content under a newer version. Require the response to be at least as new, with one exception: a handle still lacking local chunks takes the content anyway — it cannot read without it — but does not claim the response's log position. - Copy-event adoption returned without installing, so a foreign touch arriving before the copy's own event lost its timestamps. Content is unchanged either way, so the dirty pages stay valid; a clean handle now takes the entry, while a dirty one keeps its diverged version. * mount: one directory floor instead of a record per child; agree on TTL Review feedback: - Build completion wrote one KV record per direct child inside the cache write lock, so a large directory stalled every other cache operation for O(children) store writes. The directory's listing snapshot already covers every child it saw; make that floor the version for any child without a record of its own, and a child earns a record only when a later event touches it. One map write per build replaces the per-child writes, with the same fencing. - The presence probe read the store directly and so counted a TTL-expired entry as present, judging the path by a record describing content that has logically vanished. It now applies the same expiry the read path does, and an expired path falls back to its directory floor. - Preserve ErrNotFound identity when the commit-time re-read finds the object deleted, so callers still surface a 404. - Assert the rename-away source fence timestamp in the invalidation test. Also record the tombstone ceiling: distinct deleted names in a cached directory accumulate until it is rebuilt or evicted, which prunes everything at or below the new snapshot. * mount: pin the fence's clock domain instead of letting skew decide A log-position fence is stamped by one filer's clock under that filer's in-process lock, so comparing it to an event another filer logged is comparing two unrelated clocks. The two error directions are not equally costly: applying an event the fence already covered is a re-apply the base-equality check absorbs, while skipping one it does not cover leaves the handle holding exactly the state the event was meant to correct, with the subscription cursor already past it — the unhealable staleness this whole PR exists to remove. So refuse to guess. Fences now carry the signature of the filer that stamped them, and a handle records it alongside the position. An event is only fenced out when the filer that logged it is the one that stamped the fence — the logging filer appends its own signature, so its presence identifies the clock domain. Events from any other filer are applied. Positions taken from events keep comparing as before; the subscription already delivers those in order. The invalidation callback takes a struct now: it carries the path, entry, position, delete/rename distinction, and signatures, and was about to need a fifth positional parameter. * mount: follow a foreign rename; key page invalidation on content, not equality - A rename's old-path invalidation now carries the destination, and the handle follows the file there: an open fd tracks the inode, and leaving it on the old path made its next flush recreate that name instead of updating the renamed file. - Dirty pages overlay content, so only a content change invalidates them. Keying that on exact equality meant any timestamp-only event destroyed them, which the copy-adoption marker existed to paper over — a foreign touch could consume the marker and leave the copy's own event to drop the post-copy writes. Comparing content instead makes the marker unnecessary, so it is gone: a metadata-only event keeps the overlay, and a dirty handle keeps its diverged entry unless foreign content supersedes it. - A remote download response that is merely older is now refused even when the handle still lacks chunks; only an unversioned one is taken (and claims no position), since an older response's content predates what the handle reflects. - A refused or unversioned download no longer publishes to the metadata cache, where a zero-position event would clear the entry's version and let an older subscriber event roll the cache back. * mount: page invalidation keys on content alone; unversioned writes claim no position - sameEntryContent compared everything but timestamps, so a foreign chmod, chown, or xattr change counted as a content change and destroyed the dirty-page overlay. It was strict only to serve the copy-adoption marker, which is gone; its one caller now asks the question it actually needs — did the bytes change — so metadata-only events leave the overlay alone. - A rename over an existing file destroys that file, but its open handle was left live and still pointed at the name the renamed source now occupies, so its flush could overwrite it. MovePath already reports the displaced inode; mark that handle deleted. - An acknowledgment was refused whenever its position was numerically lower, even when a different filer stamped the fence it lost to. Two known, differing signatures mean unrelated clocks, so the comparison no longer applies there; unknown signatures still compare as before. - A local write with no log position behind it now records that explicitly instead of deleting its version record. Absence means the directory listing covers the path, which is why the snapshot floor applies; local content the listing never saw must not inherit it, or the events that would correct it are fenced out. * mount: widen the existing lookup functions instead of forking WithVersion twins The versioning work grew a parallel function for every accessor that needed to return a log position — lookupEntryWithVersion beside lookupEntry, maybeLoadEntryWithVersion beside maybeLoadEntry, FindEntryWithVersion beside FindEntry, AcquireFileHandleWithVersion beside AcquireFileHandle, advanceEntryVersion beside advanceEntryVersionTsNs, plus a getPbEntryWithVersion wrapper and an InsertListedEntriesForTest hook. Two names for one operation is two places to keep in step, and the split let callers pick the one that happened to compile. Each pair is now the single original name carrying the position, with callers that do not want it discarding it. filer_pb.GetEntry returns the fence its response already carried rather than a mount-side wrapper re-issuing the lookup, and InsertEntry takes the position its content reflects rather than a test-only twin that inserted without one. The one behavioural knot the merge exposed: AcquireFileHandle had been installing the entry on a pre-existing handle only in its unversioned form, which conflated 'the caller is authoritative' with 'the lookup had no version'. Deferred create is the only caller that means the former, so it now installs explicitly and the map function just acquires. |

Add codespell support with configuration and typo fixes (#10393)
* Add GitHub Actions workflow for codespell on master * Add rudimentary codespell config * Tune codespell config: skip generated code, ignore camelCase, whitelist domain terms Add camelCase/PascalCase regex to ignore common Go/Rust/JS identifiers like allLocations, publishErr, ReadInside, FlushInterval. Also skip templ-generated *_templ.go files, and whitelist a handful of short/domain-specific words (visibles, fo, te, ser, bject, unparseable, keep-alives, tread, anc, ue) that show up as false positives across the tree. Co-Authored-By: Claude Code 2.1.217 / Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Fix ambiguous typos and protect false positives Fixes typos that codespell reports with multiple candidate suggestions (so `codespell -w` cannot auto-apply them), plus one inline pragma and one config entry to protect legitimate identifiers. Manual fixes (single correct answer chosen from context): - pattens -> patterns (5x) in filer/upload/shell flag help strings - finded -> found (2x) in tarantool storage.lua comment - spacify -> specify (2x) in helm chart values.yaml comment - wether -> whether in skiplist.go docstring - simpe -> simple in mq schema test case name False-positive protection: - Add `//codespell:ignore` next to `source GET's` (possessive of HTTP verb) in s3api_object_handlers_copy_stream.go - Whitelist `auther` in .codespellrc — it's a local variable meaning "authenticator" in weed/security/tls.go, not a typo of "author". Co-Authored-By: Claude Code 2.1.217 / Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Extend codespell ignore list: .git-meta path and thirdparty groupId Also skip `.git-meta` (scratch dir for commit messages that may contain typo words verbatim) and whitelist `thirdparty` — it appears as the literal Maven groupId `org.apache.hadoop.thirdparty` in hdfs3 poms and cannot be renamed. Co-Authored-By: Claude Code 2.1.217 / Claude Opus 4.7 (1M context) <noreply@anthropic.com> * [DATALAD RUNCMD] Fix non-ambiguous typos with codespell -w Auto-applied fixes to the 44 remaining single-suggestion typos across docs, comments, log messages, tests, config, and one Java pom. === Do not change lines below === { "chain": [], "cmd": "uvx codespell -w", "exit": 0, "extra_inputs": [], "inputs": [], "outputs": [], "pwd": "." } ^^^ Do not change lines above ^^^ * Revert breaking codespell fixes; whitelist unknwon and atleast Two of the auto-applied `codespell -w` fixes were false positives that would break the build/tests: - go.mod: `github.com/unknwon/goconfig` is a real Go module path — the upstream author's GitHub handle is literally `unknwon`. Renaming to `unknown` would fail dependency resolution. - test/benchmark/fuse_db/bin/{sqlite_verify.py,run_mysql.sh,run_sqlite.sh}: `atleast` is a literal CLI mode value (a string constant compared and passed as a positional argument). Rewriting to `at least` splits it into two arguments and breaks the mode check. Reverted those files and whitelisted both words in .codespellrc so future runs won't re-suggest the same broken fixes.

S3: track manifest blob ownership through multipart completion (#10386)
* s3: track manifest blob ownership through multipart completion Manifest blobs made three orphan paths. A partial fold that failed midway kept its earlier batches on volume servers while the write fell back to flat chunks; the fold now records each saved blob and deletes them on error. A completion that failed after preparing left its fresh manifests behind on every retry; the completion state now owns them and deletes them unless a failed rollback left the version entry still holding them. And a completed upload removes its parts metadata-only, which stranded the part-manifest blobs superseded by flattening; those are collected during flattening and deleted once the completion commits. Two shared-chunk hazards nearby: the version-file rollback deleted its data, destroying the still-registered parts (worse once manifests resolve to inner chunks), and the idempotent-replay cleanup data-deleted leftover parts whose chunks the live object references. Both are metadata-only now. * s3: trim chunk manifest comments * s3: test manifest fold rollback and part range selection The fold-with-rollback and the boundary-to-byte-range logic were only exercised by hand against a live server; give both an injectable seam and cover the fold, the below-threshold and SSE no-ops, the midway failure deleting the blobs it saved, and offset-vs-legacy-index range selection including indexes that no longer address the chunk list. |

S3: fold large chunk lists into manifest chunks on the direct write path (#10383)
s3: fold large chunk lists into manifest chunks on the direct write path The S3 gateway uploads chunks itself and hands the filer a fully prepared entry. On the routed write path (ObjectTransaction) the filer stores that entry as-is, so a large PutObject or CompleteMultipartUpload persisted its whole flat chunk list - a 900GB object carries 120k chunk references in one entry. Manifestize on the gateway before the entry is written, the same way mount, WebDAV, and filer.copy prepare theirs. Multipart part boundaries also record byte offsets now: the stored chunk indexes stop matching the entry once the list is folded, and partNumber reads plus GetObjectAttributes prefer the offsets. Legacy index-only records still work, with bounds checks instead of a possible panic. Copy paths resolve a manifested source into data chunks before their per-chunk copy loops - copying a manifest chunk raw would store its blob as object data still pointing at the source - and a large copied list is folded again on the destination. Completion likewise resolves manifest chunks a part entry may carry (the filer folds an oversized UploadPartCopy range) before rebasing part offsets. |

stats: remote-mount bucket cache hit/miss metrics (#10352)
Reads of remote-backed entries now record hit or miss in
SeaweedFS_remote_cache_read_total{source,bucket,result} on the filer HTTP
path and the S3 gateway, so cache effectiveness of mounted buckets can be
graphed. Inline-content entries count as hits since they are served
locally without chunks. The filer purges the per-bucket series when the
bucket directory is deleted, so a standalone filer does not accumulate
series across bucket delete/recreate churn.

Fix object tagging writing back to the wrong object for nested keys (#10338)
Put/DeleteObjectTagging set the update directory to the bucket root for a null version, so a tag change on allowed/protected.txt landed on protected.txt at the bucket root instead. A principal scoped to one nested key could overwrite a different object sharing the basename, the same class of scope bypass fixed for PutObjectAcl. Share the object's parent-directory resolver across both paths. |

s3: accept raw semicolons in query strings (#10305)
* s3: accept raw semicolons in query strings Go's url.ParseQuery drops any key=value pair containing a raw ';'. A presigned PUT that signs content-type carries X-Amz-SignedHeaders=content-type%3Bhost; when a client or proxy decodes the %3B, the parameter vanished and the upload failed with MissingFields, while AWS accepts the raw ';' as query data. Re-encode it before routing so the pair survives parsing and signature verification. * iam, iceberg: recover raw-semicolon query pairs on the other listeners The standalone IAM API verifies SigV4 with a canonical query recomputed from the parsed query, and Iceberg REST warehouse/parent values may legally contain ';'.

s3: enforce role trust policy on direct OIDC bearer authentication (#10302)

A federated user could act as a role that AssumeRoleWithWebIdentity would refuse to issue a session for with the same token. Run the same trust-policy validation before returning the principal on the bearer path. |

s3: verify SigV4 against each plausible reverse-proxy host (#10284)
* s3: verify SigV4 against each plausible reverse-proxy host A portless X-Forwarded-Host leaves the client's true port ambiguous: a proxy that kept the Host header makes the backend Host port right, one that rewrote it makes X-Forwarded-Port right, and a client on the scheme's default port signed no port at all. The verifier bet on the backend Host port whenever the hostnames matched, so nginx-style $host/$server_port forwarding got SignatureDoesNotMatch whenever the proxy and backend share a hostname. Try each plausible host value in likelihood order instead of guessing one. * s3: unbracket IPv6 X-Forwarded-Host before matching the request host net.SplitHostPort strips brackets from the request host, so a bracketed portless X-Forwarded-Host like [::1] never matched and lost its port candidate. * s3: cover unbracketed IPv6 forwarded-host candidates; compare with slices.Equal |

s3: keep listing when empty directories fill the listing window (#10280)
* s3: keep listing when empty directories fill the listing window doListFilerEntries issued a single ListEntries request per directory with Limit = maxKeys+2. Entries that emit nothing - empty directories, the .uploads folder, the marker echo - consume that window without consuming maxKeys, so a bucket whose first window held only empty directories was reported empty and not truncated, and a subdirectory whose window filled up silently dropped the entries behind it. Keep requesting from the last received entry until the quota is filled or a short window shows the directory is exhausted. * s3: test listing across windows of empty directories The test filer client now honors StartFromFileName so repeated windows advance like the real filer. * s3: propagate the request context into directory listing RPCs A disconnected client now cancels the ListEntries streams instead of letting the listing keep issuing requests against the filer. * s3: group per-directory listing parameters into a request struct doListFilerEntries took ten positional parameters; call sites read as string and bool soup.

s3: tear down the emptied .versions directory on last-version delete; drain existing residue (#10278)
* s3: routed last-version delete removes the emptied .versions directory The routed versioned delete (routedDeleteSpecificVersion) repoints the latest pointer and deletes the version file, but unlike the lock-path fallback (updateLatestVersionAfterDeletion) it never tears down the .versions/ directory it just emptied. The residue keeps the key's read path in the self-heal rescan loop: every GET of the deleted key logs event=surfaced plus a GetObject error until the background EmptyFolderCleaner gets to the directory — at least two minutes away on its delay queue, and possibly never (the queue is in-memory, bounded, and gated on the bucket's allow-empty-folders policy). Veeam's lock arbitration probes deleted lock keys continuously, so those windows are always open and the log spam is chronic. ObjectMutation DELETE gains remove_empty_parent: after the child delete, the filer best-effort removes the parent directory in the same locked transaction. Non-recursive on purpose — a concurrent write that lands a new version fails the removal instead of being lost with it. The routed last-version delete sets it on the version-file DELETE, matching the lock-path fallback's contract. Claude-Session: https://claude.ai/code/session_014mMYAHXZySkCCUfpRFNtSv * s3: drain empty .versions residue on read heal and in s3.versions.audit Directories already stranded by pre-teardown deletes (or dropped from the EmptyFolderCleaner's bounded in-memory queue) previously re-entered the self-heal rescan on every GET forever: the heal only cleared the pointer and nothing ever removed the directory, and s3.versions.audit counted the state as clean. When the heal rescan finds no remaining version, remove the directory outright (non-recursive, so orphan children still block and fall back to the pointer clear) and log event=healed mode=empty_dir_removed; the next GET takes the clean not-found path. The audit gains an empty category so the residue is visible, and -heal removes such directories in bulk. Claude-Session: https://claude.ai/code/session_014mMYAHXZySkCCUfpRFNtSv |

s3: fail over routed object writes when the owner filer is unreachable (#10251)
* s3: fail over routed object writes when the owner filer is unreachable A routed object write (multipart completion, PUT, delete, versioned finalize, metadata replace) dialed the ring-selected owner filer directly with no failover. After a filer restarts onto a new address the lock ring can still name the old one, so every routed write hangs on the dead address until the gateway is restarted; CompleteMultipartUpload in particular exceeds client timeouts. Route the transaction through withFilerClientFailover, skipping an owner that recently failed, so a live filer forwards it to the real owner by route_key. Mirrors the read path's getObjectEntryRoutedByKey. * s3: fail over bucket-config writes when the owner filer is unreachable patchBucketEntry dialed the bucket's ring owner directly, so a restarted filer's stale ring address hung every bucket-config write (versioning, lifecycle, object lock, ownership, ACL, policy, CORS) - the same failure as routed object writes. Route it through objectTxnOnFiler so it skips an unreachable owner and a live filer forwards by route_key. |

s3api: optimize encodePath memory allocations (#10252)
* Optimize s3api encodePath to eliminate O(n^2) allocations encodePath built its result via string concatenation in a loop, which is O(n^2) in allocations. For non-ASCII (e.g. Chinese) runes it additionally called make + hex.EncodeToString + strings.ToUpper per byte (~10 allocations per character). Under high QPS with long non-ASCII object keys this produced a very high allocation rate, frequent GC and long GC pauses, causing S3 request latency spikes. Replace with a preallocated strings.Builder, a manual hex lookup table, and a zero-allocation fast path. EncodePath now delegates to encodePath to remove the duplicated implementation. Output is byte-for-byte identical, verified by TestEncodePath and TestEncodePathEqual. Benchmark (long Chinese path): 261 -> 1 allocs/op, 35810 -> 480 B/op, 7.5x faster. Load test (50M calls): 212x fewer allocations, 76x fewer GC cycles. * s3api: drop regexp from encodePath fast path The unreserved-character scan already decides whether any byte needs encoding, so reservedObjectNames.MatchString was a redundant second pass that also ran the RE2 engine on every authenticated request. Rely on the scan alone; output is unchanged. The ASCII fast path drops from ~188ns to ~11ns per call. --------- Co-authored-by: LiuDoge <liudoge@LiuDogedeMacBook-Air.local> Co-authored-by: Chris Lu <chris.lu@gmail.com> |
