* iceberg: adapt to twmb/avro v1.8.0 and iceberg-go defensive copies

avro v1.8.0 changes Schema.Root() to return *SchemaNode, which breaks
iceberg-go v0.6.0's internal avro_schemas.go. The fix (apache/iceberg-go#1843)
is only on iceberg-go's main branch, unreleased, so bump iceberg-go to
that commit (c210509) alongside the avro bump.

That iceberg-go revision also changes two behaviors seaweedfs worked
around:

- It now infers a manifest list's format version from the embedded
  writer schema, so a list missing the "format-version" header entry
  (DuckDB's shape is read as v2, not v1. ReadManifestList's header
  patching is now a redundant safety net; tests updated to expect v2.

- It returns defensive copies from DataFile.Partition(), so the
  ReadManifest shim's in-place partition normalization was silently
  discarded. Rebuild the entry through NewDataFileBuilder when any
  partition value is normalized, copying every other DataFile field so
  manifest round-trips are preserved.

- It converts day-transform partitions to iceberg.Date on read
  (applyDayTransformDates), so the day-partition cases the shim and
  tests guarded now convert without help; tests updated to expect
  iceberg.Date from the raw read.
EOF
)

* iceberg: accept assert-ref-snapshot-id without snapshot-id

iceberg-go's new nullableInt64 parser rejects an assert-ref-snapshot-id
requirement whose "snapshot-id" field is absent from the JSON, even
though the Iceberg REST spec makes it optional (null means the ref must
not already exist). v0.6.0 used a plain *int64, so absent was nil and
accepted. ClickHouse sends the requirement without snapshot-id when
asserting a branch does not yet exist, so its writes fail with
"missing required field \"snapshot-id\"".

normalizeRequirements splices an explicit null into any
assert-ref-snapshot-id requirement missing the field before handing
the JSON to iceberg-go's parser, restoring the v0.6.0 behavior across
both iceberg-go versions.

* iceberg: fix v1 block_size_in_bytes default in rebuilt manifest entries

rebuildManifestEntry set block_size_in_bytes to 0, but the v1 manifest
schema requires the default of 64 MiB ("Always write default in v1").
The original value is not exposed on the DataFile interface, so use the
spec default. Also clarify the fallback comment to note that empty
(zero-record / zero-byte) files also trigger it, not just a nil spec.

Add a round-trip test that writes a rebuilt entry as v1 and verifies
block_size_in_bytes is 64 MiB via Avro decoding.

Chris Lu 70a26cb5d2 s3: gate IAM-cache gRPC RPCs behind admin Bearer auth (#11190)
* s3: gate IAM-cache gRPC RPCs behind admin Bearer auth

The SeaweedS3IamCacheServer registered on the S3 gateway's internal gRPC
port (default 0.0.0.0:18333) accepted PutIdentity/RemoveIdentity/PutPolicy/
DeletePolicy/GetPolicy/ListPolicies/PutGroup/RemoveGroup with no per-RPC
authentication. An unauthenticated network peer could call PutIdentity with
Actions:[Admin] and write straight into the live accessKeyIdent map that
the SigV4 path reads, bypassing S3 authentication entirely.

Mirror the filer's IamGrpcServer.checkAdminAuth: require a Bearer token
signed with jwt.filer_signing.key (read from the existing s3a.filerGuard)
at the top of every IAM-cache RPC. With no key configured the check is a
no-op, matching the rest of SeaweedFS's gRPC surface.

* credential: attach admin Bearer token to S3 IAM-cache propagation

The filer's PropagatingCredentialStore fans IAM mutations out to peer S3
servers over the SeaweedS3IamCache gRPC service. Now that the S3 handlers
require a Bearer token signed with jwt.filer_signing.key, attach one to the
outgoing propagation context (mirroring shell/iamAdminAuthContext). With no
key configured it is a no-op, so deployments that run without the signing
key keep working.

* credential: mint IAM-cache admin token after master discovery

propagateChange attached the admin Bearer token before ListClusterNodes,
so master-client retries could run down the (default 10s) token lifetime
before the peer S3 fan-out began, leaving peers to reject an expired token
and IAM caches stale. Move withIamCacheAdminAuth to after discovery
succeeds, immediately before the propagation timeout is derived.

* credential: cap IAM-cache propagation timeout below JWT lifetime

The propagation fan-out used a fixed 10s timeout. If an operator
configures jwt.filer_signing.expires_after_seconds below 10, the admin
token can expire while slower S3 peers are still being contacted, leaving
their IAM caches stale. Derive the propagation deadline as
min(10s, tokenTTL) so it never outlives the token. withIamCacheAdminAuth
now returns the token's lifetime (0 = no expiry) for this purpose.

Chris Lu f35e2ccf21 s3: warn when a lifecycle change leaves fast-path-stamped objects on their old TTL (#11184)
* s3: warn when a lifecycle change leaves fast-path-stamped objects on their old TTL

The per-write TTL fast path (opt-in via s3.bucket.lifecycle.fastpath)
stamps a volume TTL at PutObject time that can't be taken back. When an
operator lengthens or removes an Expiration.Days rule (or deletes the
bucket lifecycle) on a fast-path-enabled bucket, objects already written
keep their baked-in TTL and won't be rescued by the change — unlike the
default worker-driven path, which re-evaluates the current rules each
pass. This is the data-loss direction described in #11183.

Surface it: Put/DeleteBucketLifecycle now emit a glog warning and set
X-Seaweed-Lifecycle-Fastpath-Warning on the response when the change
removes, disables, lengthens, or re-scopes a fast-path-eligible rule.
Shortening a rule does not warn (old objects simply expire later, not
data loss). Tag-only and overflow-day rules are never on the fast path
and never warn.

Addresses the warning half of option 2 in #11183.

* s3: address review — emit warning after mutation succeeds, fix ID-rename false positive

Two issues raised by CodeRabbit, Greptile, and Devin reviews:

1. Failed mutations retained the warning header. The warning was set on
   the ResponseWriter before storeBucketLifecycleConfiguration /
   clearStoredBucketLifecycleConfiguration was called; if that failed,
   the error response carried a warning for a change that was never
   applied. Now the reason is computed before the mutation but the log
   and header are emitted only after it succeeds.

2. Rule renames produced false "removed" warnings. fastpathRuleKey used
   Rule.ID as the sole identity when present, so renaming a rule (same
   prefix/size/days, different ID) treated the old rule as removed.
   Replaced with two-pass matching: first by ID, then by fast-path
   predicates (prefix + size). An ID-only rename with unchanged
   predicates and days no longer warns. Greedy matching ensures each
   new rule is consumed by at most one old rule.

Added regression tests: ID-only rename (no warn), rename + lengthen
(warn), rename + shorten (no warn).

f99c4a1f14 s3: make RenameObject idempotent for a retried request (#11178)
* feat(s3): make RenameObject idempotent for a retried request - #10661

A rename that succeeds but whose response is lost leaves the client with
no safe move: retrying returned 404, because the source is already gone,
so a retry was indistinguishable from a rename that never happened.

The destination now carries what the rename that created it was, under
x-seaweedfs-rename-token: the client's token, the source key and the
time. A retry that names the same token and the same source and
destination is answered 200 without touching anything. The same token
sent for a different rename is refused with 409 rather than silently
answered, and a token older than 24 hours is treated as unrelated so a
key cannot answer for a request indefinitely.

Requests without the header behave exactly as before.

* s3: answer a reused rename token with 409, not 400

The PR promised Conflict and the code returned Bad Request. 400 tells a
client its request was malformed and invites it to give up; this request
is well formed and resending it unchanged will not help, because what it
collides with is a rename the same token already stands for.

The status code is now asserted in a test, since it is the part of this
behaviour a client actually acts on.

* Update weed/s3api/s3err/s3api_errors.go

* s3: fix rename token review notes

- ErrIdempotentParameterMismatch returns 409 Conflict, not 400. The
  comment and TestRenameTokenReuseAnswersConflict both expect 409; the
  code regressed to 400 in a later commit.
- stampRenameToken: clarify that markRenameToken mutates srcEntry in
  place, so the token reaches the destination via the move regardless
  of whether the UpdateEntry succeeds. The precondition only guards the
  pre-move write, not the move itself.
- Extract the handler retry branch into retryRenameDecision and add
  TestRetryRenameDecision, covering the source-still-exists fallthrough
  that was previously reasoned about but not tested.

* s3: IdempotentParameterMismatch returns 400, matching AWS docs

The AWS S3 RenameObject API documentation specifies HTTP Status Code: 400
for IdempotencyParameterMismatch. Revert the previous 409 change and align
the comment and test with the documented behavior.

Chris Luanddevin-ai-integration[bot] 811b8b5734 make the remote-mount cache wait configurable per mount (#11168)
* add a per-mount cache_wait_ms to the remote storage mount mapping

A read of an uncached remote-only object waits on a hardcoded size tier
before it can fall back to the origin, so every ranged read of a large
remote-only object pays that wait. Carry the wait in the mount mapping so
it can be tuned, or set to zero, per mount.

* resolve the cache wait of an uncached remote-only read from its mount

The wait came only from the object size, so an operator could not trade
cache hits for time to first byte. Both read paths now resolve the mount
covering the object and let its cache_wait_ms replace the size tiers.

* read straight from the remote when a mount waits zero for its cache

A mount used as a streaming source pays the cache wait on every ranged
read of an object too large to finish caching, and the caching itself is
wasted work. A zero wait now skips the cache call, so both read paths go
to the origin immediately.

* let remote.mount set the cache wait of a mount

remote.mount -cacheWait=0 turns a mount into a streaming source, and any
other duration trades cache hits against time to first byte.

* keep the size based wait for a version-specific read

A read pinned to a version cannot fall back to the origin, since the
mounted remote only holds the current key, so a mount that opts out of
caching would leave it on the 503 retry loop forever.

* let the operator allow a remote-only read to dial an internal endpoint

The remote-mount read paths in the filer and the S3 gateway always refused
an endpoint resolving to a loopback or private host, so a mount backed by
an internal S3 could never be read from its origin, only through the local
cache. Both now take the allowance the volume server already has, still
off by default.

* skip the background cache of a mount that waits zero for its cache

GetObjectHandler kicks off caching for every remote-only read, so a mount
serving as a streaming source kept downloading whole objects even though no
read ever waited for them.

* cover a zero cache wait end to end

The read has to reach a real origin, so the harness also opts the filer and
the S3 gateway into dialing the loopback remote it already allows for the
volume server.

* resolve the S3 cache wait once so the background cache follows it too

The background cache that GetObjectHandler starts read the mount on its
own, so it skipped a version-specific read that the foreground path still
waits for. Both now ask the same resolver.

* answer 404 when the origin of a zero-wait read is gone

Metadata can outlive the object it points at, and with no cache to fill
the read would sit on the 503 retry path forever. The remote backends
already report a missing object as ErrRemoteObjectNotFound.

* open the origin at write time for a multipart range

Every part of a multipart Range is prepared before any is written, so
opening eagerly would hold one origin connection per part and leak the
ones already opened when a later part fails to open.

* reject a cache wait shorter than a millisecond

The mapping stores milliseconds, so -cacheWait=500us truncated to zero
and silently turned caching off instead of waiting.

* restore the doc comment of cacheRemoteObjectForStreamingWithShortTimeout

Extracting the wait resolver left its comment on the new function.

* stat the origin before committing a multipart range

Opening at write time keeps no connection through the preparation, but it
also moved a failure past the point where the multipart body picks the
response status, so a gone origin truncated a 206 instead of answering
404. One stat up front puts the status back.

* stat the origin once per request

Every part of a multipart Range is prepared on its own, so the preflight
ran once per range instead of once per read.

* map Azure and GCS stream not-found to ErrRemoteObjectNotFound

ReadFileAsStream on Azure and GCS returned provider-specific not-found
errors instead of ErrRemoteObjectNotFound, so a zero-wait read of a
deleted object was misclassified as a transient cache failure and
retried indefinitely. Map BlobNotFound and ErrObjectNotExist the same
way StatFile already does.

* Update weed/remote_storage/gcs/gcs_storage_client.go

Eliah RusinandChris Lu cfa8afec92 filer: guard FoundationDB 100KB value limit and pack earlier (#11161)
* filer: guard the FoundationDB value size limit, not the transaction limit

An entry's whole chunk list is one FoundationDB value, and FDB caps a value at
100,000 bytes while a transaction may reach 10MB. UpdateEntry checked the
transaction limit, so every entry between the two limits passed the guard and
was rejected by FDB itself with error 2103 (Value length exceeds limit). The
failure surfaced inside the store rather than at the guard, so the S3 layer
dropped the connection and clients saw a network fault instead of an error.

Check the value limit in UpdateEntry and KvPut instead, after gzip and before
the transaction, with an error that names the limit it hit. The removed
transaction-size constant guarded nothing else: DeleteFolderChildren batches by
entry count.

Refs #11158

* filer: fold at 500 chunks in the foundationdb build

Manifest packing is what keeps a large file's entry small, but it only ran once
a flat chunk list reached 10000 chunks. A FoundationDB value stops at 100,000
bytes and an entry's whole chunk list is one value, which at ~100 bytes per
chunk record is about 1000 chunks -- so on FDB the write always failed before
packing could help: a 3.3 GiB PutObject at the default -maxMB=4 was already
past the limit.

FoundationDB support is its own build (`go build -tags foundationdb`, shipped
as its own image), so the batch is a build-time choice and needs no negotiation
at run time. The tagged build folds at 500, every other build keeps 10000 and
is untouched.

500 is not arbitrary: a single fold level leaves (chunks/batch) manifest
pointers plus up to (batch-1) unfolded chunks in the entry, so the reachable
chunk count is highest when the two terms are near equal. For a 100,000-byte
budget that optimum is 500, which holds an entry inside the limit up to
~250,000 chunks -- ~1 TB at -maxMB=4, against ~4 GB before. Larger files need
nested packing, which no batch size substitutes for.

One binary serves every role in that image, so the filer and each client that
folds -- S3, mount, WebDAV, weed shell, filer.copy -- agree on the batch by
construction. A binary built with the tag but pointed at another store folds
earlier than that store requires, costing one manifest blob per 500 chunks and
one read to resolve it.

Fixes #11158

* filer: fold with rollback inside MaybeManifestize, not beside it

A fold that fails midway has already uploaded manifest blobs for its earlier
batches, and returns only the data chunks -- dropping the manifests it had
separated out of the caller's list. Both were wrong in ways that mattered:

  - AppendToEntry assigned that shortened list straight to entry.Chunks and
    created the entry, so an append to an already-folded file whose fold
    failed lost every previously folded chunk. weed mount had the same shape.
  - cleanupChunks logged the error as "not good, but should be ok" and then
    returned it through a named result, failing the whole CreateEntry or
    UpdateEntry, while the blobs it had written stayed behind referenced by
    nothing.

The S3 path was alone in handling this, through a private helper beside
MaybeManifestize. A second entry point next to the one everything else calls
just means the wrong one gets used, so the behaviour moves inside
MaybeManifestize: on failure it returns inputChunks as it received them, and
hands the blobs it saved to a deleteChunks callback. The filer, S3 and
filer.copy pass their existing deleters -- filer.copy already cleans up this
way after a failed upload -- and mount, WebDAV and weed shell pass nil, which
reports the blobs rather than collecting them, as before. Each caller keeps its
own error policy: the filer HTTP PUT path and filer.copy still fail the request,
the rest still continue with the flat list, which is a correct entry.

Chris Lu 5a515adab2 s3: HeadObject with partNumber returns the part's size and 206 (#11166)
* s3: HEAD with partNumber reports the part's size and range

HeadObject set its headers from the total object size and then only
validated the partNumber, so a client probing part 1 with HEAD got the
whole object's Content-Length and a 200 while the same GET returned the
part's size, a Content-Range and a 206.

Resolve the part's byte range before the headers are written, through the
range logic GetObject already used, and answer a partNumber HEAD as the
ranged HEAD that AWS documents.

* s3: answer an unsatisfiable partNumber with 416 InvalidPartNumber

GET and HEAD rejected a partNumber past the number of parts with 400
InvalidPart, the code for a missing part in CompleteMultipartUpload. AWS
answers a read of a part that does not exist with 416 InvalidPartNumber,
which lets a client probing for the part count tell the two apart.

The ceph suite pins RGW's 400 InvalidPart here, so the s3tests jobs patch
that expectation the way they already patch prefix ordering.

* s3: keep the whole-object checksum off a partNumber response

The stored checksum covers the whole object, so it is already withheld
from a ranged read. A partNumber HEAD now describes one part while the
request carries no Range header, so exclude it there too rather than
handing a client a checksum that does not match the bytes described.

* s3: resolve a partNumber against the parts the object records

Completion accepts ascending, not consecutive, part numbers, so the part
count is not the highest part number. Comparing the two rejected an
uploaded part 3 of a two-part object, and let a request for the absent
part 2 fall through to the positional chunk lookup and serve part 3's
bytes. Ask the recorded boundaries for the part instead, and keep the
count comparison for objects written before boundaries were stored.

* s3: apply a client Range within the part on HEAD too

GET narrowed the part by a Range sent alongside partNumber; HEAD reported
the whole part, so the two disagreed again for a request that carries
both. Move the narrowing into the shared range lookup so either verb
describes the same bytes.

Chris Luandbruce-zzz 0f05957bc4 filer: self-heal chunk manifest reads when volume locations go stale (#11107)
* filer: self-heal fetchWholeChunk on stale volume locations

Upstream #10156/#10800 wired cache invalidation into the buffer-based
read paths, but manifest resolution still goes through fetchWholeChunk,
which returns the raw error on failure. When cached volume locations
are stale (volume tiered to remote storage, server rolled), resolving
a large multipart file fails permanently even though other locations
are healthy.

Thread the ChunkGroup's cacheInvalidator through ResolveChunkManifest /
ResolveOneChunkManifest / fetchWholeChunk, and on failure invalidate,
re-lookup and retry once via the existing retryFetchWithFreshLocations
helper. The streaming bytesBuffer is reset before the retry so partial
bytes from the failed attempt cannot corrupt the manifest
proto.Unmarshal. Non-mount callers pass nil and keep their semantics.

* filer: move the manifest self-heal tests in with the other manifest tests

Also make the stale server stream a prefix and then abort mid-body, which is
what actually leaves partial bytes in the buffer: an HTTP error status returns
before ReadUrlAsStream ever calls the writer, so a 500 never exercised the
Reset the tests claimed to cover.

Claude-Session: https://claude.ai/code/session_01FK3oGC5ZVeJYvNBWgb9JUD

* filer: keep the cached volume locations when a manifest read is cancelled

A cancelled or timed-out read says nothing about where the volume lives, so
dropping the location and going back to the master only costs the next reader
a round trip. PrepareStreamContentWithThrottler already guards its self-heal
this way. The guard also goes inside retryFetchWithFreshLocations, since the
caller can be cancelled between its own check and the invalidation, and that
covers the reader cache and prefetch paths too.

fetchWholeChunk returns the context error rather than the stream failure it
provoked, and ResolveOneChunkManifest wraps with %w so errors.Is still sees it.
That matters even where no invalidator is passed: volume.fsck resolves
manifests with nil and tells its own abort from a corrupt manifest that way,
so the cancellation check sits ahead of the nil-invalidator return.

Claude-Session: https://claude.ai/code/session_01FK3oGC5ZVeJYvNBWgb9JUD

* filer: self-heal manifest reads on the filer and s3 paths too

Every caller that already holds the location cache backing its lookup function
can hand it over: the filer's read, copy and deletion paths and the log cache
have the MasterClient right there, and s3api has the FilerClient. MinusChunks
takes one for the same reason, since the deletion path resolves manifests
through it. Only the shell tools and the replication sinks, whose lookup
functions cache privately with nothing to invalidate, keep passing nil.

Dmitriy PavlovandChris Lu 1d0b97f4c6 avro: field time.Time <> iceberg.date (#11091)
* iceberg: normalize foreign day partitions during manifest rewrite

* test: cover manifest rewrite with foreign day partitions

* iceberg: restore every foreign partition value, not just day transforms

iceberg-go takes a partition field's logical type from the last branch of
its Avro union, so a writer that spells an optional partition [<type>, null]
rather than [null, <type>] leaves the value as whatever the Avro decoder
produced. A day or date partition then arrives as a time.Time the manifest
writer cannot encode, and a time partition is worse: time.Duration converts
to int64 nanoseconds and silently records the wrong value.

ReadManifest sits next to ReadManifestList, the other shim for what foreign
writers put on the wire, and converts each partition value back to the
Iceberg representation for its field type.

Claude-Session: https://claude.ai/code/session_01FdQyRuWF9SuCnPn21iH9yR

* iceberg: read manifests that carry partition values through the shim

Compaction, delete rewrite and their detection passes read entries and write
the same partition values back into new manifests, so they fail on a foreign
day partition exactly as manifest rewrite does. Where filters see it too:
literalMatchesActual falls through to fmt.Sprint, so a time.Time renders as a
timestamp and never matches the day the user asked for.

The two remaining readers, orphan collection and the admin preview, only look
at file paths and stay on iceberg.ReadManifest.

Claude-Session: https://claude.ai/code/session_01FdQyRuWF9SuCnPn21iH9yR

* iceberg: convert partition values before the writer rebinds logical types

Dimonyga checked the manifests of a live Doris table: every input spells the
partition union null-first, with the date logical type present, so the union
ordering is not what breaks the merge.

The conversion is lazy. iceberg-go converts what the Avro decoder returned on
the first Partition() call, using the logical types read from the manifest
being parsed, and ManifestWriter.addEntry rebinds them to the manifest it is
about to write before it makes that call. A day partition is where the two
disagree -- iceberg-go's day transform reports an int32 result type, so the
manifest it writes carries no date logical type at all -- and an entry nobody
looked at in between converts against that and keeps its time.Time.

That is why only rewrite_manifests failed: compaction and delete rewrite group
entries by partitionKey(df.Partition()) first, which converts them, and a where
filter does the same. Reading every entry's partition here converts them all
while the manifest's own logical types are still in place.

96242a2be2 s3: ListParts on a completed or unknown upload answers NoSuchUpload (#11081)
* s3: ListParts on a completed or unknown upload answers NoSuchUpload

complete/abort delete the .uploads/<id> directory, but most filer stores list
a missing directory as empty rather than erroring, so listObjectParts answered
200 with an empty Parts list for an upload that no longer exists -- the same
response an open upload with no parts yet gets. AWS (and Ceph/RGW, MinIO)
answer NoSuchUpload, and clients lean on that: tusd derives the resumable
upload offset from the ListParts part sizes, so every completed upload read
back as zero bytes received.

Probe the upload record before listing, the way completeMultipartUpload
already does: not found, or a directory a late part write resurrected without
the destination key, answers NoSuchUpload. An open upload with no parts keeps
answering 200 with an empty list.

S3 carries the flexible-checksum members of CompleteMultipartUploadResult in
the XML body, not in response headers, so every SDK read back an empty
checksum from an upload that asked for one.

Claude-Session: https://claude.ai/code/session_01Huux1uh7JxAbf8yypMYrMk

* s3: echo the checksum algorithm and type from CreateMultipartUpload

The upload directory already records both, but the response dropped them, so a
client could not confirm which checksum its parts had to carry.

* test: multipart upload reports the object checksum it was asked for

Covers every algorithm end to end: the create response echoes the algorithm and
type, the complete response carries the checksum, and it matches what a later
HEAD reports.

Chris Lu 86761cc7d5 filer: keep empty folders that are s3tables catalog entries (#11102)
* s3tables: build the catalog attribute keys from one shared prefix

Every attribute the catalog stores on a bucket, namespace, table or view
entry is spelled out with the same literal prefix. Name it once in
s3_constants so code outside the package can recognize a catalog entry
without repeating the string.

Claude-Session: https://claude.ai/code/session_01GfZsc4cyNB2yr6KYLRv9q1

* filer: keep empty folders that are s3tables catalog entries

A namespace, table or view is a directory whose extended attributes are
the catalog record. Its files can live elsewhere - a rename moves only
the catalog pointer and leaves the data at the old path, and a view has
no files at all - so an empty one is still a live entry.

Drop a table, then rename another table onto that name: the drop queues
the old table's folders, the rename recreates the name path, and two
minutes later the cleaner deletes it and cascades into the namespace,
losing a table the catalog still lists.

Claude-Session: https://claude.ai/code/session_01GfZsc4cyNB2yr6KYLRv9q1

* filer: drop a queued cleanup when the folder is created again

A cleanup is queued against the folder that was found empty. If that
folder is deleted and a new one takes its name, the queue entry outlives
the folder it was about and the next pass deletes the replacement. A
drop followed by a rename onto the dropped name does exactly this: the
name path comes back as a live catalog entry two minutes before the
queue is read.

Chris Lu 9ea52db219 s3: validate the version-id header used as a filer path segment (#11097)
* s3: reject a version-id header that is not a valid path segment

putToFiler stored the client-supplied Seaweed-X-Amz-Version-Id header
verbatim into object metadata. That value is later read back and used
as a filer path component when building the .versions/v_<id> path, so a
value containing "/", "\" or ".." could steer retention/legal-hold
writes and remote-cache reads outside the object's own bucket tree.

Validate the header with isValidVersionID before storing it, the same
check the versioned read paths already apply, and reject the request
otherwise. Server-set version ids ("null" and generated hex) pass.

Claude-Session: https://claude.ai/code/session_011QqNaxZwnpHgMoAZNp3RkY

* s3: validate a stored version-id before using it as a path

The retention and legal-hold sinks build a .versions/v_<id> path from a
version id read back out of object metadata, and the remote-cache path
builder does the same from either the request or the stored id, without
the isValidVersionID check the other version-id consumers apply. Guard
these so a value that is not a valid path segment falls back to the
regular / unversioned path instead of steering the write or read out of
the bucket tree.

recursivelyCheckLocksWithClient tested EntryHasActiveLock only on
non-directory entries, so a directory-marker object (an S3 key ending
in "/") that carries retention or a legal hold was recursed into but
never lock-checked. DeleteBucket then saw no locks and removed the
bucket, destroying an object under active Object Lock along with the
rest of the bucket. DeleteObject already enforces the lock on the same
key, so the two paths disagreed.

Check the directory entry for an active lock before recursing.

AuthorizeCopySource and AuthorizeObjectDelete both authorize a key the request

change.

POST Object uploads (presigned-POST / HTML form) authorized the write with only

authorizeObjectKeyAction via a new AuthorizeObjectWrite so it is authorized like
the equivalent PUT.

Chris Lu 34f5442e9b s3api: push the listing prefix down to the filer in ListObjectVersions (#11070)
The version walk listed every directory with no prefix, transferring
all 1024-entry batches over gRPC and filtering gateway-side - and kept
paging past the point where names can no longer match. On wide
directories (many sibling orgs/jobs next to the requested prefix) that
is most of the transfer, decode, and CPU cost of every page.

Derive the next path component of the requested prefix per directory
level and hand it to the filer listing. A name holds no slash, so a
directory whose name does not start with the component cannot contain
a matching key and a file that does not cannot be one; stores with
native prefixed listing (sql, leveldb) turn this into a range scan and
stop the stream at the end of the prefix zone.

Chris Lu 81ca5cb6c6 s3api: drop two redundant filer round-trips per listed version entry (#11068)
* s3api: drop two redundant filer round-trips per listed version entry

ListObjectVersions paid two avoidable getEntry calls while walking a
bucket, both re-fetching data the walk already held:

- getObjectVersionList re-read the .versions directory entry that every
  caller had just received from listing the parent directory (or from
  its own sibling probe). Pass the entry down instead: one RPC saved
  per object listed.

- getObjectOwnerFromVersion, on a version with no stamped owner,
  re-fetched the same version entry its OwnerID had been extracted
  from. The refetch cannot answer differently, so data written before
  owners were stamped cost one futile RPC per listed version, forever.

All round-trips on this path are sequential, so on large versioned
buckets (Veeam-style workloads) they add up to a visible share of
per-page latency and gateway CPU.

Chris Lu 4c9cbf72bc s3api: stop retrying a definitive NotFound in getLatestObjectVersion (#11067)
The .versions lookup retried every error through the full backoff
ladder, so a missing key spent 12.7s (8 attempts, 100ms..6.4s) before
the pre-versioning fallback could answer. NotFound is an answer, not a
transient failure: gate the retries on isRetryableFilerErr, the same
classifier retryFilerOp already uses, which also stops retrying for
callers whose context is canceled or past its deadline.

GetObject already treats NotFound on .versions/ as definitive; this
brings the retention/tagging/ACL/attributes/delete/copy paths that go
through getLatestObjectVersion in line with it.

Chris Lu ba5b14b457 master, filer, s3api: bound the collection deletes that strand a caller (#11026)
* master: bound each volume server DeleteCollection, and finish the fan-out

A collection delete fanned out to every volume server holding it with
context.Background(), so a server that accepted the connection and then
went quiet held the whole delete open with nothing to end it. Each RPC is
bounded now, on the same budget allocateVolumeTimeout gives the other
master-to-volume-server admin RPC. The volume server runs the delete to
completion regardless of the request context, so giving up costs the
confirmation and not the deletion.

The walk itself is the caller's, not a per-server one:

- It outlives the caller. A cancelled request must not abandon a
  destructive fan-out part-done, with volumes left behind and no request
  still running to come back for them.
- It no longer stops at the first server that refuses, which left the
  collection on every server after it in the list. The first failure is
  still what is reported, and the collection stays in the topology so a
  later delete comes back for the rest.
- It sends one RPC per server rather than one per replica.
  ListVolumeServers reports a node once for every replica it holds, while
  DeleteCollection removes the whole collection from the server it
  reaches, so a collection with thousands of volumes repeated the same
  whole-collection delete thousands of times over.

Both passes run too. Returning after a failed normal pass left the
collection's EC shards in place with nothing left to retry them.

Claude-Session: https://claude.ai/code/session_01EnB1fbryyKc2LetRZxQPTP

* master: delete the EC shards behind /col/delete too

The HTTP handler carried its own copy of the volume-server walk and only
ever ran the normal pass, so a collection deleted through it kept its EC
shards. It shares the gRPC path now, which also gets it the bounded RPCs
and the one-per-server fan-out.

Claude-Session: https://claude.ai/code/session_01EnB1fbryyKc2LetRZxQPTP

* filer: bound the collection delete a bucket delete leaves behind

Deleting a bucket entry deletes its collection afterwards, deliberately
detached from the request so a client that hangs up cannot strand the
bucket's volumes. Detached meant unbounded, though: with the master down
or mid-election the wait for a leader has nothing to end it, so the
handler parks, and the client retrying behind it parks another.

It keeps outliving the request and now carries a deadline of its own. The
budget bounds the wait, not the work: the master keeps deleting on its own
fan-out once asked, so giving up costs the confirmation.

Claude-Session: https://claude.ai/code/session_01EnB1fbryyKc2LetRZxQPTP

* s3api: bound the collection RPCs a bucket creation and deletion issue

Neither carried a deadline, so a transient failure anywhere down the chain
held the S3 request open until the client gave up on it. Both budgets are
taken outside the filer failover walk, so one budget covers the whole walk
rather than granting each filer a fresh one.

The walk itself stops when that budget is spent, and stops without blaming
anyone: the caller's own expiry is not evidence against the filer that was
answering, and the next filer has no time left to answer in either.
Recorded as a filer failure, a slow master upstream would flag every filer
in the walk, and the three failures that open the circuit take unrelated
object reads down with them.

* s3api: a failed collection listing no longer fails a bucket creation

PutBucket lists collections to notice a leftover one it is about to reuse.
The result feeds a warning and nothing else -- s3a.exists is what decides
whether the bucket already exists -- yet a transient failure of that
listing returned 500 and refused the creation. It is advisory now, so a
failure is logged and the creation continues, exactly as it does when the
listing returns false.

* s3: reject a part whose upload was aborted while its body was in flight

The upload-exists check runs before the part body is read. An abort answered
during the read deletes the upload directory, and the part write that follows
re-creates it, so the aborted upload is listed nowhere yet completes.

Re-check after the write: only createMultipartUpload stamps the destination
key on .uploads/<id>, so a directory without it is one the part write
resurrected. Drop it along with the part and answer NoSuchUpload.

Claude-Session: https://claude.ai/code/session_01ByZ49KQdUtHhmjG6SpNczT

* s3: reject a copied part whose upload was aborted mid-copy

UploadPartCopy has the same window as UploadPart: the upload-exists check
runs before the bytes are copied, and the part write that follows re-creates
the directory an abort removed. Both the re-encryption and the raw-copy path
re-check before answering.

Claude-Session: https://claude.ai/code/session_01ByZ49KQdUtHhmjG6SpNczT

* s3: do not complete an upload whose directory holds no upload record

A .uploads/<id> directory that a part write created rather than

Claude-Session: https://claude.ai/code/session_01XqaJrwgXQ5GSUpyzRbe5nD

* s3: thread the request context through the unversioned delete path

doDeleteEntry issued every DeleteEntry on context.Background(), so an S3
client that hung up left the gateway working on its behalf, out of reach of
both cancellation and the per-request retry allowance that
DeleteMultipleObjectsHandler installs.

Claude-Session: https://claude.ai/code/session_01XqaJrwgXQ5GSUpyzRbe5nD

* s3: treat a cancelled filer RPC as terminal, not transient

isRetryableFilerErr matched context.Canceled and DeadlineExceeded by
sentinel, which only holds while the error is still local. Once it has
crossed gRPC it is a status, so an abandoned request was retried six times
on behalf of a caller that had already gone.

Claude-Session: https://claude.ai/code/session_01XqaJrwgXQ5GSUpyzRbe5nD

* s3: replay a delete whose reply the transport dropped

A delete is idempotent at the filer, which answers an entry that is already
gone with an empty resp.Error, so a reply lost in transit can be reissued
rather than surfaced. Surfaced, it becomes a 500 on the bucket delete, which
boto3 resends and is then answered NoSuchBucket, or a per-key InternalError
inside the 200 of a multi-object delete, which no SDK retries at all.

The replay runs through retryFilerOp, so it draws on the allowance the
request already installs rather than paying a backoff per key, and stops for
a caller that has gone. rm and rmObject re-enter WithFilerClient per attempt,
so each one walks the failover list again on a connection the failed attempt
had invalidated; the multi-object loop holds one client for the batch, so
there the replay reuses it.

Classification stays structural. The filer reports its own refusals in
resp.Error, which carries no status and has the deleted path - and, for a
recursive delete, the children it stopped on - formatted into it, so no key
name can steer the decision either way.

rm and rmObject now take the caller's context. Cleanup and rollback paths
pass context.Background() deliberately: they have to run whether or not the
caller is still waiting.

* util, pb: classify a filer error by the status the server sent

DoSeaweedListWithSnapshot wrapped a failed ListEntries with %v, dropping the
gRPC status, so IsTransientError fell back to matching substrings against a

* s3: keep the bucket and prefix out of the list retry decision

A bucket named transport, or a prefix under logs/unavailable/, made a
PermissionDenied listing look transient and got it retried; a key holding the
not-found sentence suppressed a retry that should have run. Both checks now
read the filer's status, and only fall back to the text when there is none.

The filer put the non-empty-folder marker behind its own "delete directory %s"
wrapper and the gateway matched it as a substring, so a key named after the

request answered 204. Keep the marker leading the message that crosses the
wire, turn it back into a sentinel where the response is read, and match that.

Chris Lu fdd8bd9478 s3: reject a request that names two operations (#10987)
The router matches bucket subresource routes in registration order while
the IAM action resolver matches its own list in a different order, so a
request carrying two operation subresources is authorized as one
operation and served as another. `PUT /bucket?policy&tagging` resolves to
s3:PutBucketTagging and runs PutBucketPolicy, letting an identity
delegated bucket tagging install an arbitrary bucket policy. The same
mismatch reaches PutBucketCors, PutBucketLifecycle, PutBucketVersioning,
PutObjectLockConfiguration, PutBucketRequestPayment and the policy and
cors deletes.

Reject the ambiguity where the other pre-routing checks live, so neither
list has to stay in step with the other. Keys that modify an operation
rather than select one -- versionId, partNumber, prefix -- still combine
freely.

Chris Lu 2a97e08caa s3: cover the directory marker key with object lock (#10988)
* s3: enforce object lock when deleting a directory marker

The key "dir/" is deleted the unversioned way, ahead of the branches
that enforce Object Lock, so a principal with plain delete permission
could remove a key the gateway was reporting as COMPLIANCE-retained --
retention set through PutObjectRetention is stored on the directory
entry and served back by GetObjectRetention, only the delete ignored it.

The same path also takes any key ending in "/" regardless of size, while
a PUT only makes a marker of one up to 1KiB. A larger one is a genuine
versioned object, and deleting it here dropped its whole history after
the versioned delete of the same key had been refused.

Enforce in the marker delete itself, so the single, versioned and
multi-object delete paths are all covered.

* s3: apply object lock headers on a directory marker PUT

The trailing-slash branch runs before the versioning and Object Lock
handling, so it accepted x-amz-object-lock-* headers and stored none of
them: a bucket owner could believe a key was retained while nothing
recorded it, and an invalid mode or a past retention date that a regular
key rejects came back 200 here.

Validate the headers the way the regular path does, store what they ask
for beside the owner the same callback already sets, and refuse to
replace a key that is already retained.

* s3: check every version a marker delete would remove

The marker delete clears any history under the key in one recursive
removal, while the lock check ahead of it resolves the latest version
only. A version retained under an unretained one was taken with the
rest, so enforce against each version the removal covers.

* test: pin the marker lock refusals to AccessDenied

A bare require.Error passes on any failure, including one that has
nothing to do with the lock. Assert the code, the key the batch delete
reports, and that the marker survives each refusal.

* s3: check the history entries a version list leaves out

The version list skips an entry without a version id, while the removal
takes it with the rest, so an entry an older build left unnamed escaped
the check. Walk the history directly instead, and refuse when an unnamed
entry is still under a retention or a legal hold of its own.

* s3: let a governance bypass reach an unnamed history entry

The unnamed branch refused every active retention, so a caller allowed
to bypass governance could not clear one, which the named path lets
through. Refuse a legal hold and compliance mode as before, and take the
bypass into account for governance.

* s3: keep the object lock decision in one place

The unnamed history entry had to repeat the retention and legal hold
rules inline because the enforcement helper only takes a key to look up.
Split the part that judges an entry out of it and call that from both.

* s3: guard a marker PUT on the entry it replaces

The overwrite check resolved the key's latest version, but mkdir builds
a fresh entry for the marker itself, dropping the lock metadata the old
one carried. Once the key had a history, an unlocked version answered
for a retained marker and a plain PUT replaced it. Judge the entry the
write is about to replace instead; a versioned write of the same key
still adds a version, which is its own to allow.

* s3: guard a marker delete on the entry it removes

The check ran against the key rather than the entry, so once the key had
a history it answered with a version and the retention recorded on the
marker itself went unseen. Judge the entry that is about to be removed,
the same way the PUT side now does; the versions under it are still
covered by the walk that follows.

* s3: take the object write lock for a marker PUT

The overwrite check read the entry that the mkdir after it replaces, so
two marker PUTs could both pass while one was still unlocked. The marker
delete already runs under this lock; hold it across the check and the
mkdir so the entry cannot change in between, and so the two paths are
serialized against each other.

Chris Lu ab8b34720a s3tables: delete only the location the dropped table owns (#10986)
DeleteTable authorizes the named table, then recursively purges the data
path derived from its stored MetadataLocation. That location is supplied
by the caller at create/register time and never bound to the table, so a
tenant allowed to drop one table could point it at a table in a sibling
namespace and have the delete destroy that table's catalog entry and
data files.

A legitimately decoupled location -- a rename source, or a leftover the
name was reused over -- has had its catalog attributes stripped, so a
surviving metadata marker identifies a path that belongs to another
entry. Refuse those, alongside the existing ancestor refusal.

Chris Lu 0b5fff2ccd filer, s3: reuse the volume server's guarded remote-storage client builder (#10990)
* volume: build the guarded remote storage client through a shared helper

Fold the endpoint validation, credential check and rebinding-safe dialer
that FetchAndWriteNeedle applies before dialing a caller-supplied remote
storage endpoint into a single BuildGuardedRemoteStorageClient helper, so
other callers that dial the same endpoints can reuse it. No behavior
change on this path.

streamFromRemote serves a cold remote-only entry straight from its mounted

Chris Lu 28862c866e Authorize an Iceberg table create before it writes (#10991)
* s3tables: share one CreateTable authorization gate

CreateTable and RegisterTable each carried their own copy of the name
validation, policy load and permission check. Fold them into
authorizeCreateTable, and expose it on the Manager for callers that write
into a table bucket before the table itself is registered.

Claude-Session: https://claude.ai/code/session_01QiJkka1T2NAWDWq4JQ8Vuy

* iceberg: authorize a table create before it writes

Stage-create returns before the S3Tables registration that authorizes a
create, and the plain create writes its metadata file before reaching it,
so a caller who may not create the table could still leave a staged
template, a marker and a v1.metadata.json in the target bucket - and get
vended credentials for a location of their choosing. Run the CreateTable
gate as soon as the table is known to be absent.

Claude-Session: https://claude.ai/code/session_01QiJkka1T2NAWDWq4JQ8Vuy

* iceberg: authorize a create-on-commit the same way

A commit against a table that does not exist creates it, writing the
metadata file first and only then reaching the registration that checks
the caller may create it. Denied callers saw a 500 for what is a 403.

Claude-Session: https://claude.ai/code/session_01QiJkka1T2NAWDWq4JQ8Vuy

* iceberg: pin that identity actions reach the create gate

The manager request is built from the caller's own context, so an identity
whose actions carry the permission still passes. Worth a test: a fresh
context here would silently deny every such caller.

Chris Lu d8a189f07f s3: keep a missing object a 404 under If-Match and If-Unmodified-Since (#10985)
* s3: keep a missing object a 404 under If-Match and If-Unmodified-Since

GET and HEAD resolved the target before evaluating the conditional headers, and
a missing target failed If-Match and If-Unmodified-Since outright, so absence
surfaced as 412 PreconditionFailed. AWS reports the missing object instead:
404 for HeadObject, NoSuchKey for GetObject, and 412 only when a live object
fails the condition. Clients cannot tell absence from a stale precondition
without an extra racy HEAD, so OpenDAL disabled its four conditional
stat/read capabilities against SeaweedFS.

A precondition now only fails against an object that exists; a missing one --
including a latest version that is a delete marker -- returns NoSuchKey.

Claude-Session: https://claude.ai/code/session_01X4kEbuwxd9DFsTnSXjfjgv

* s3: evaluate a conditional read against the version the request names

GET and HEAD resolved the latest version before evaluating the conditional
headers, so a request carrying versionId had its If-Match compared against a
different version than the one it was asking for: a live version whose ETag the
client held failed once a newer version -- or a delete marker -- became the
latest. resolveObjectEntry now resolves the named version on a versioned bucket,
the way DELETE already does.

A named version that resolves to nothing is left to the handler, which alone
knows whether the bucket is versioned and so whether it owes NoSuchVersion.

Chris Lu f5f1dcbd8c s3: keep verifying the request host when externalUrl is set (#10970)
* s3: keep verifying the request host when externalUrl is set

externalUrl was the only host candidate once set, so a client that dialed
the gateway directly instead of through the proxy always got
SignatureDoesNotMatch. Make it lead the candidate walk instead: every
candidate still needs a valid signature, and the request-derived hosts are
already trusted when the flag is unset, so a mixed proxy plus in-cluster
topology can now advertise a public endpoint and verify both planes.

* s3: cover virtual-hosted addressing behind externalUrl

The old pin also rejected an external client that signed
bucket.api.example.com, since only the bare externalUrl host was ever
tried. The candidate walk covers it; pin the case down.

Chris Lu 3431bdcb74 s3: fix UploadPartCopy with volume-data encryption (#10971)
* operation: give an encrypted chunk the plaintext ETag

With -encryptVolumeData the volume server stores ciphertext, so it cannot
echo a Content-MD5 back and the chunk lands with an empty ETag. Every ETag
derived from those chunks then comes out empty for a single chunk, or
d41d8cd98f00b204e9800998ecf8427e-N for several.

The caller already hashes the plaintext to send as Content-MD5, so keep that
digest as the chunk ETag instead of dropping it, and compute it for a
WantMd5 caller under cipher too.

* s3: re-encrypt a part copy from a volume-encrypted source

UploadPartCopy raw-copies source chunks when neither side uses SSE, which
also caught -encryptVolumeData sources. Those chunks are ciphertext a
whole-chunk cipher key decrypts, so copying a byte range out of one and
keeping the key leaves a destination that fails authentication on GET, and
the copied chunks carry no ETag for the part result to report.

Route them through the re-encrypting path already used for SSE: it reads the
source as plaintext, hashes the part, and writes the destination under the
gateway's own encryption.

* s3: fetch only the range a part copy asked for

The re-encrypting UploadPartCopy path opened the source at offset 0 and threw
the prefix away, so assembling an object part by part read the source once per
part. Now that volume-encrypted sources take this path too, that is the common
case rather than an SSE corner.

The chunk stream already seeks, so hand it the range.

* s3: reject an unsatisfiable copy-source-range

A part copy has no way to report a short part, so a range reaching past the
source cannot be clamped the way a GET clamps one. The fast path silently
produced a part shorter than asked for, or an empty one; the re-encrypting
path pads with zeros, so a 2 MiB source copied as bytes=1048576-9999999 came
back as 1 MiB of data followed by 7.5 MiB of nothing.

Answer InvalidRange instead, which is what s3-tests'
test_multipart_copy_invalid_range expects.

Chris Lu 368b2035b2 s3: deny anonymous access when the identity config loads no identities (#10954)
* s3: deny anonymous requests when the identity config loads no identities

Naming a config file is the operator asking for authentication. A file that
yields no identity - an unpopulated secret mount, or a mistyped top-level key
the proto parser silently drops - left the gateway open to every anonymous
caller: ListBuckets returned 200, and anonymous PUT could create buckets and
write objects.

* s3: name the unknown top-level keys in an identity config

The proto parser discards what it does not recognise, so a mistyped
"identites" loads as an empty config. Naming the dropped keys at startup turns
the resulting lockout into a one-line diagnosis.

* s3: isolate the auth-enforcement tests from AWS environment credentials

* s3: use a singular "identity" as the unrecognised-key example

Codespell rejects the misspelling the example used.

Chris Lu d2c470af1b S3: commit SSE GET status only after the first read succeeds (#10935)
The SSE streaming path kept writing 200/206 from filer metadata before
fetching or decrypting anything, so a missing needle or failed decrypt
setup surfaced as a broken 200 body. Same deferral as the plain path:
the status commits on the first body write, and every failure before
that returns to the handler for a clean S3 error response.

Chris Lu d9d5fab35b S3: commit GET status only after the first read succeeds (#10930)
streamFromVolumeServers wrote the 200/206 status from filer metadata
before any byte had been fetched from a volume server, so a missing or
corrupted needle surfaced as a broken 200 body and the request metrics
recorded a success. Defer the status commit to the first body write: a
failed first read now returns a clean 500 before headers, while the
wire timing of successful responses is unchanged since net/http buffers
the status line until body bytes arrive anyway.

Chris Lu 863fec6c3f S3: let a key that is a prefix of other keys be an object (#10912)
* filer: keep the sentinel when CreateEntry reports an update failure

CreateEntry flattened the error UpdateEntry wraps, so errors.Is stopped
matching and ErrExistingIsDirectory and ErrExistingIsFile never reached
the S3 mapper, which answered a retryable 500 instead.

* s3: let a key that is a prefix of other keys be an object

S3 keys are flat, so "a/b" and "a/b/c" are independent objects that
coexist in either write order. The filer stores a key as a path, so one
of them has to live on the directory the other is nested under.

Writing the nested key first refused the prefix key outright. Writing it
second promoted the file to a directory, which kept its data but lost the
key: an empty object left nothing to recognise it by and disappeared, and
one with data listed under a trailing slash it never had.

Mark the directory that carries such a key, and write the object onto it
when the path is already a directory. The mark makes an empty prefix
object visible to listings and readable by GET and HEAD, keeps the empty
folder cleaner off it, and lists it under the key it was written with.
Deleting the key strips the mark back off along with the data.

* filer: keep a TTL off a directory that stands for an object

An expired entry is deleted a row at a time, so expiring a directory
removes it and leaves everything under it unreachable. Promoting a file
to a directory carried its TTL across, and a promoted file is exactly the
one that has keys nested under it.

Drop the TTL on promotion, and leave one an older build wrote alone. The
lifecycle worker still expires the object, through the delete that leaves
the directory behind.

* s3: delete the null version of a key other keys are nested under

The routed delete cannot remove an entry that other keys live under, and
answered a retryable 500 rather than falling back to the lock path the
unversioned delete already falls back to. That path then looked the entry
up under the bucket with the whole key as its name, so the demote wrote it
back one directory too high and failed as not found.

Fall back on any non-precondition error, and split the key before deleting
it. Trailing-slash directory markers with children reach the same delete.

* filer: keep the sentinel when MkFile and Mkdir report a create failure

Same flattening one layer out: every mkFile caller lost the sentinel, so
a CopyObject onto a key that other keys are nested under answered a
retryable 500 where a PutObject of the same key answers 409.

* s3: copy and rename a key that other keys are nested under

Such a key is stored on the directory those keys live in, and copy and
rename both refused it: the source lookup maps every directory entry to
NoSuchKey, so a key a plain GET serves could not be copied or moved, and
the destination side refused it as a directory conflict.

The source is read through a view of the entry as the object it names.
The destination is written the way a PutObject of that key writes it. A
rename at either end copies the object's own data across and strips it off
the source key rather than going through AtomicRenameEntry, which moves a
directory by moving everything under it - the nested keys are not part of
what is being renamed.

Chris Lu 69cc2869ad Fixes from the review of the admin bucket policy UI (#10907)
* admin: treat a missing S3 Tables policy as an empty load, not an error

The bucket/table policy GET relayed the backend's 404 NoSuchPolicy to the
dialog, whose loader treats any non-OK response as a load failure and
keeps Save and Delete blocked. A bucket or table without a policy could
never be given one. Return policy null instead, the same contract
ShowBucketPolicy uses for classic buckets.

* admin: reject policy documents the structured editor would misread

A top-level JSON array passed the object guard (typeof [] is 'object')
and loaded as a zero-statement policy, which the next commit would
rewrite to an empty document. Object elements in Action/Resource were
coerced to '[object Object]' and saved that way on the s3tables surface,
which stores policies verbatim. Both now throw, which routes the
document to the JSON tab like other unrepresentable shapes.

* admin: let the JSON tab save documents the structured editor can't model

Save with the JSON tab active required a round-trip through
policyDocToEditorState, so exactly the documents the dialogs shunt to
'JSON tab only' mode (unrepresentable Effect, Resource+NotResource, and
the like) could never be saved - Delete was the only mutation left.
Invalid JSON still blocks; an unrepresentable document now saves and the
editor state stays marked unparsed.

* admin: pin the policy editor to what each consumer's backend supports

The s3tables evaluator has no NotResource/NotPrincipal fields - it
silently drops them, turning Allow+NotResource into allow-everything and
making Deny+NotPrincipal inert - and it only matches s3tables: actions
against s3tables ARNs, while the editor suggested s3: actions and
arn:aws:s3::: resources. New registerPolicyEditor knobs: allowNegation
hides the Not* modes and routes documents using them to the JSON tab;
resourceSuggestions pins the Resource autocomplete to the open
resource's ARN; the S3 Tables dialogs get an s3tables-only action
datalist. requirePrincipal now also hides NotPrincipal, which
policy_engine.ValidateBucketPolicy always rejects, and the client-side
check requires Principal specifically to match that server rule.

* admin: save S3 Tables policies from a button, not form submission

The multi-input structured editor sits inside a form whose Save button
was type=submit, so Enter in any single-line editor input - accepting an
autocomplete suggestion, say - implicitly submitted whatever half-built
statement the editor held, and the backend stores the document verbatim.
A lone statement with no Principal matches nobody, locking out every
non-owner. Save is now an ordinary button and the form ignores
submission.

* admin: block zero-statement policy saves

Committing the active tab before the emptiness check made 'Policy JSON
is required' dead code: an empty editor serializes to {"Statement":[]},
which the s3tables backend stores verbatim - evaluated default-deny for
every non-owner, while the statement-count column keeps showing 'Not
configured'. All three policy dialogs now refuse a save with no
statements and point at Delete instead. The classic bucket modal only
gained a clearer message; the server already rejected the document.

* admin: guard S3 Tables policy mutations against stale and overlapping requests

The save/delete completions ran against whatever resource the shared
modal happened to show by then: a slow PUT for one bucket would hide the
modal mid-edit of another and misattribute its alerts, a late DELETE
cleared the shared textarea over the newly opened resource with its
loaded flag set, and nothing stopped a double-click from firing two
overlapping mutations. Ported the classic modal's pattern: capture the
target on start, flag the mutation in flight with the buttons disabled,
and only touch the UI when the completion still matches the open
resource. Success now reloads the page, which also keeps the Policy
column's statement count honest.

* admin: confirm before deleting an S3 Tables policy

Delete Policy sat next to Save and fired on a single click; with
default-allow enabled one stray click silently dropped the resource
policy and left the bucket open to every principal. Same confirmation
the classic bucket modal already has.

* admin: let a corrupt stored bucket policy be shown, fixed, and deleted

A stored document the decoder rejects made the policy GET 500, and with
the loaded flag never set the modal blocked both Save and Delete - the
one policy an operator most needs to remove was the one they couldn't,
even though the delete path never reads the document. The GET now
returns the raw bytes alongside a null policy; the dialog hands them to
the JSON tab and unblocks the buttons.

* admin: url-encode the bucket name in the policy API calls

The filer lists any directory under the buckets path, names S3 would
never allow included; one carrying '#' or '%' broke the fetch URL or
addressed a different name than the modal shows.

* admin: drop stale edit-policy responses on the IAM policies page

The same race the bucket and S3 Tables dialogs already guard against:
open one policy's editor while its GET stalls, open another, and the
late response populates the editor under the second policy's name -
Update then saves the first policy's statements over the second.

* admin: warn before a bucket policy save drops unsupported fields

The editor tracks unmodeled top-level keys precisely so
confirmPolicyFieldDiscard can warn before the server's Version+Statement
decode discards them, but only the IAM page called it; the bucket modal
saved a pasted document with e.g. a console-generated Id without a word
while the editor kept displaying the field.

* s3: enforce the bucket policy size cap on both surfaces

The 20KB cap lived only in the admin UI, so a larger policy stored via
the S3 API displayed there but could never be re-saved, desyncing the
two writers the cap comment claimed could not desync. The constant now
lives in policy_engine next to the shared validator and PutBucketPolicy
rejects oversized documents with PolicyTooLarge, matching AWS.

* admin: ship the policy editor's fieldset styles with the editor

The .policy-stmt-* rules that undo Bootstrap's full-width legend reset
stayed behind in policies.templ when the editor markup moved to the
shared script, so the bucket and S3 Tables dialogs rendered Actions/
Resource/Principal as full-width jumbo headings. PolicyDatalists is the
component every consumer already renders once; the styles live there
now.

* s3: mirror bucket policy changes into the IAM store from the metadata subscription

The advanced-IAM path appends the bucket-policy:<bucket> document to
every STS/session evaluation, but only this gateway's own PutBucketPolicy
maintained that mirror - a policy tightened or created through the admin
UI (or another gateway) never reached it, so revoked access stayed live
indefinitely, and the delete side was an unimplemented TODO in any case.
The metadata subscription now diffs the stored policy on every bucket
entry change and updates or removes the mirror, covering all writers and
deletion with one mechanism; IAMManager gains the missing
RemoveBucketPolicy.

* admin: deduplicate the bucket policy write path

Set and Delete carried line-for-line identical filer closures;
bucketPolicyMutation already treats nil as clear-the-key. The shared
helper sits below Set's validation, since ValidatePolicy cannot take the
nil document Delete passes.

* s3: drop ValidateBucketPolicy's re-checks of ValidatePolicy rules

Both callers run ValidatePolicy first, which already enforces the
version and at-least-one-statement rules; the duplicates were dead code
with drifted error text.

* admin: seed a new statement's Resource from the pinned suggestions

A fresh statement on the S3 Tables dialogs started with no resource row
at all; seed it with the broadest pinned ARN the same way cfg.bucket
already seeds the classic modal.

* admin: refuse to save Not* fields the backend would silently drop

Hiding the NotResource/NotPrincipal modes was not enough where negation
is disallowed: the JSON tab accepts any valid document (that is its
job), and a statement's Advanced-fields box can reintroduce the keys, so
an s3tables save could still store fields the evaluator drops - turning
Allow+NotResource into allow-everything. commitPolicyActiveTab now runs
a final document-level check over what would actually be saved; Delete
stays available for cleanup.

* s3: move the IAM bucket policy mirror on a bucket rename

A same-directory rename delivers one event carrying both entries, and
the byte-equality short-circuit skipped the new name's mirror when the
policy was unchanged - while the replayed delete for the old name
removed its mirror, leaving the renamed bucket unmirrored. The mirror
decision is now a pure function that removes the old name and writes the
new one regardless of byte equality, with the rename cases unit tested.

* s3: backfill the IAM bucket policy mirror on lazy bucket loads

The metadata subscription only mirrors changes, so a policy that
predates the IAM integration never reached the bucket-policy:<bucket>
mirror and its grants did not bind on the IAM path until the policy was
next modified. The gateway is deliberately lazy at startup (nothing
lists all buckets), so the backfill hooks the same place a bucket's
policy first becomes known: the cold bucket-config load. EnsureBucketPolicy
writes only when no mirror is stored, so repeat loads cost one cached
read.

* s3: reconcile the bucket policy backfill against concurrent changes

The backfill's check-then-write could race an event-driven mirror update
or removal and re-store bytes that were already stale, with no later
event to heal it. EnsureBucketPolicy now reports whether it wrote, and a
write is reconciled against a fresh authoritative entry read: a changed
policy is re-mirrored, a removed one is removed. Anything changing after
that read fires its own event, which finds the backfill's write already
present and supersedes it. The backfill also carries the entry's raw
bytes rather than a re-marshaled document, so the reconcile can
byte-compare.

* s3: prime the bucket policy mirror before advanced-IAM authorization

The backfill ran from the lazy bucket-config load, but IAM authorization
evaluates the bucket-policy:<bucket> mirror before any handler runs - a
grant carried only by a not-yet-mirrored policy denied forever, and the
denied request never reached the code that would have loaded the bucket.
authorizeWithIAM now primes the bucket config first (an in-memory cache
hit once warm), and the backfill runs synchronously on the cold load so
the very first authorization already sees the mirror.

Mathieu Arnold e931cccc7b Manage bucket policies via the admin ui (#10895)
* admin: manage S3 bucket policies from the admin UI

Bucket policies were only manageable through the S3 PutBucketPolicy API;
the admin UI had no equivalent to the quota/owner/lifecycle editors it
already offers. Add GET/PUT/DELETE for a bucket's policy, sharing the
exact validation the S3 gateway uses.

- Extract validateBucketPolicy/validateResourceForBucket out of
  s3api_bucket_policy_handlers.go into policy_engine.ValidateBucketPolicy /
  ResourceMatchesBucket so both the S3 API and the admin UI enforce
  identical rules.
- weed/admin/dash/bucket_policy.go: Get/Set/DeleteBucketPolicy, writing
  through ObjectTransaction + PATCH_EXTENDED (the lifecycle pattern) so a
  concurrent owner/quota/lifecycle change on the same bucket entry isn't
  clobbered. Propagation to every S3 gateway is automatic via the existing
  filer metadata log subscription. The S3 gateway's IAM policy mirror is
  deliberately not replicated here (its delete path is already an
  unimplemented TODO on the S3 side).
- New GET/PUT/DELETE /api/s3/buckets/{bucket}/policy routes, CSRF-guarded
  on writes.
- Bucket list and details modal now show a statement-count badge, read
  from the entry already fetched (no extra RPC).
- UI: a JSON-textarea policy editor modal, matching the lifecycle modal's
  structure.

* admin: reuse the visual policy editor for bucket policies

Extract the structured policy editor (add/remove statement, action/
resource/principal rows with autocomplete, JSON tab kept in sync) out of
policies.templ's inline script into a shared
weed/admin/static/js/policy_editor.js, and wire the bucket policy modal
in s3_buckets.templ up to it instead of a bare JSON textarea.

- registerPolicyEditor(which, config) replaces the hardcoded create/edit
  id derivation with a per-instance config (textarea/tab/body ids,
  datalist ids, requirePrincipal, bucket). The IAM policies page keeps its
  exact pre-extraction ids via two registerPolicyEditor calls, so its
  markup is unchanged.
- New policy_datalists.templ exposes the three shared <datalist>s
  (actions/resources/principals) as @PolicyDatalists(), now rendered by
  both policies.templ and s3_buckets.templ.
- requirePrincipal seeds new bucket-policy statements with Principal: "*"
  and adds a client-side check before save (the server, via
  policy_engine.ValidateBucketPolicy, remains the actual authority); the
  bucket config pins the Resource autocomplete to the open bucket instead
  of fetching every bucket in the cluster.
- layout.templ loads policy_editor.js globally, after admin.js/
  modal-alerts.js (basePath/escapeHtml/showAlert) which it depends on.

3a (the extraction) is a byte-preserving move verified against the
unchanged policies.templ behavior before layering 3b's parameterization
and the bucket-policy wiring on top.

* admin: migrate S3 Tables bucket/table policy editors to the shared editor

Third consumer of the shared visual policy editor: the S3 Tables bucket
and table policy modals (a bare JSON textarea each) now get the same
structured Editor/JSON tabs as the bucket policy and IAM policy pages,
via registerPolicyEditor('s3tablesBucketPolicy'/'s3tablesTablePolicy',
{ textareaId: ... }). Storage and validation are untouched - S3 Tables
policies still go through their own s3tables.PolicyDocument type and the
s3tables.policy extended attribute, unrelated to policy_engine and
s3-bucket-policy; only the editor UI is shared.

Fix a real bug surfaced by adding this second load path: the bucket
policy modal (and the naive first draft of this s3tables port) called
commitPolicyTextareaToEditor() right after a GET and then force-switched
to the Editor tab. commitPolicyTextareaToEditor() is designed to leave
the current tab in place and the editor state untouched when a document
fails to parse (so an in-progress edit survives a bad tab switch), so
forcing the Editor tab afterwards could show empty/stale editor state
that a careless Save would then serialize over a perfectly valid but
structurally-unusual stored policy. Add
loadPolicyTextareaIntoEditor(which) to policy_editor.js, which has no
"current tab" to defer to and instead falls back to the JSON tab with an
alert on a document the structured editor can't represent - the same
safety editPolicy already had in policies.templ - and use it at all three
"populate the editor right after a GET" call sites (bucket policy,
S3 Tables bucket policy, S3 Tables table policy).

* admin: show policy statement count on the S3 Tables buckets page

Mirrors the "Policy" column already added to the classic S3 buckets
list: a clickable badge with the statement count when the table bucket
has a resource policy, "Not configured" otherwise. S3 Tables policies
are a separate mechanism (s3tables.PolicyDocument under the
s3tables.policy extended attribute) from the S3 bucket policy work
elsewhere in this branch (policy_engine.PolicyDocument /
s3-bucket-policy), so this is a parallel implementation of the same
pattern rather than shared code.

- S3TablesBucketSummary gains PolicyStatementCount, populated in
  GetS3TablesBucketsData from entry.Entry.Extended[s3tables.ExtendedKeyPolicy]
  via the new extractS3TablesPolicyStatementCountFromEntry - no extra RPC,
  the entry is already fetched for ExtendedKeyMetadata.
- The badge reuses the existing .s3tables-bucket-policy-btn class, so it
  opens the same policy modal as the row's action button with no JS
  changes.

* admin: don't let a failed policy GET open the door to an empty overwrite

loadS3TablesBucketPolicy/loadS3TablesTablePolicy cleared the textarea,
then unconditionally called loadPolicyTextareaIntoEditor() regardless of
whether the GET actually succeeded - including when fetch() rejected or
the response was not ok, silently logged to console only. That leaves
the structured editor holding a legitimate-looking empty policy
({version, statements: []}), with the Editor tab active by default.

If Save is then clicked, commitPolicyActiveTab() serializes that empty
state into the textarea as `{"Version":"2012-10-17","Statement":[]}` -
a non-empty string - before the "Policy JSON is required" guard ever
sees it, so the guard passes and the transient load failure gets
written over whatever policy was actually stored.

Add s3tablesBucketPolicyLoaded/s3tablesTablePolicyLoaded, set true only
once a GET has actually completed (ok, including a genuinely empty
policy) and false on any failure path (fetch rejection or a non-ok
response, which previously fell through silently). Both submit handlers
now check the flag before touching the editor at all, and a failed load
surfaces via alert() instead of only a console.error - the user
previously had no visible indication the load had failed.

Verified with a jsdom simulation driving the real rendered page against
a stubbed fetch: a failed GET followed by Save now sends no PUT at all
(previously it sent Statement: []); a successful GET followed by Save
still PUTs the loaded policy unchanged.

* admin: address code review findings on the policy editor

1. policy_editor.js: policyEditors is only pre-populated for 'create'/
   'edit'; every other `which` (bucket, s3tablesBucket, s3tablesTable)
   stays undefined until its first successful async load. Nothing in
   this file enforces that a page hide its Editor/JSON tabs and
   Add-statement button until that load completes - the S3 Tables policy
   modals don't - so a click in that window (e.g. Add statement, or
   switching to the JSON tab) threw "Cannot read properties of undefined
   (reading 'unparsed')". Add policyEditorState(which), which lazily
   initializes a default state, and route addPolicyStatement, the
   jsonTabBtn 'show.bs.tab' handler, commitPolicyActiveTab, and
   renderPolicyEditor through it. Verified with a jsdom simulation
   against a never-resolving fetch: the exact click threw on the
   pre-fix code and no longer does.

2. s3_buckets.templ: the bucket-policy Save handler checked the
   textarea for emptiness before calling commitPolicyActiveTab(), which
   is what actually serializes the structured Editor tab's fields into
   that textarea. A policy entered entirely through the Editor tab (the
   primary path - never touching the JSON tab) left the textarea at
   whatever it was at load time, so creating a new policy this way hit
   "Enter a policy document" and Save silently did nothing. Move the
   commit before the emptiness check, preserving the existing alert and
   early-return. Verified with a jsdom simulation: Add-statement then
   Save (no tab switch) now PUTs the entered statement; before the fix
   the same sequence never reached fetch().

3. s3tables_buckets.templ / s3tables_tables.templ: the policy Editor/
   JSON nav-tabs were missing the ARIA roles Bootstrap's own tab pattern
   expects (role="tab"/"tabpanel", aria-selected, aria-controls,
   aria-labelledby) - screen readers had no way to tell these were tabs
   or which pane went with which button. Added the standard Bootstrap 5
   tab markup to both.

* admin: guard policy load/save flows against overlapping requests

1. s3tables.js: loadS3TablesBucketPolicy/loadS3TablesTablePolicy had no
   protection against overlapping loads. Opening one bucket's (or
   table's) policy dialog and then another's before the first GET
   resolved let the late response write its document into the shared
   textarea and mark the dialog "loaded" while it was now targeting the
   second resource - a subsequent Save would then push the first
   resource's policy onto the second. Add a per-load monotonic sequence
   number (s3tablesBucketPolicyRequestSeq / s3tablesTablePolicyRequestSeq,
   the same pattern already used for the classic bucket-policy load in
   s3_buckets.templ); a response is only applied - textarea, loaded flag,
   editor state - if its captured sequence still matches the latest one
   issued.

   Verified with a jsdom simulation: bucket A's policy load (artificially
   slow) followed immediately by bucket B's (fast) previously left A's
   policy in the textarea once A's late response landed; it now correctly
   keeps B's.

2. s3_buckets.templ: the bucket-policy Save button lives outside the
   (initially hidden) editor wrapper, so it stays clickable while a load
   is still in flight - the existing policyRequestSeq guard only protects
   the *load* from a stale response, not Save from firing before any
   load for the current bucket has completed. Add bucketPolicyLoaded,
   reset before each GET and set only once the matching response lands,
   and check it at the top of the Save handler.

   Verified with a jsdom simulation: clicking Save immediately after
   opening the dialog, before a (deliberately never-resolving) GET
   settles, now sends no PUT; a normal load-then-save sequence still
   PUTs the loaded policy unchanged.

* admin: address further code review findings on the policy editor

1. s3tables.js: loadS3TablesBucketPolicy/loadS3TablesTablePolicy only
   reset the JSON textarea when a new load starts; the structured editor
   kept showing the previously loaded resource's statements (Editor tab
   is the default active one) until the new fetch resolved. Call
   loadPolicyTextareaIntoEditor() against the now-cleared textarea
   immediately, so switching resources visibly resets the editor right
   away instead of only once its own load completes. Verified with jsdom:
   opening bucket A (loads fully) then bucket B (GET never resolves) no
   longer leaves A's statements visible in B's editor.

2. s3tables.js: deleteS3TablesBucketPolicy/deleteS3TablesTablePolicy had
   no loaded-state check, so a failed GET (which already blocks Save)
   left Delete fully able to remove the resource's stored policy sight
   unseen. Add the same s3tablesBucketPolicyLoaded/s3tablesTablePolicyLoaded
   guard Save already uses. Verified with jsdom: delete after a failed
   load now sends no DELETE; delete after a successful load is unaffected.

3. s3_buckets.templ: the bucket-policy Editor/JSON nav-tabs were missing
   the same ARIA roles already added to the S3 Tables policy tabs in an
   earlier round (role="tab"/"tabpanel", aria-selected, aria-controls,
   aria-labelledby) - this instance was out of scope for that review
   comment but is the same gap. Bootstrap's own tab.js already manages
   aria-selected on tab switch once the attribute exists, so no extra JS
   was needed.

4. s3_buckets.templ: neither the bucket-policy Save nor Delete handler
   guarded against a double-click, or against firing while the other was
   still in flight - two overlapping PUT/DELETE requests for the same
   bucket could land in either order. Add a shared
   bucketPolicyMutationInFlight flag: set (and both buttons disabled)
   before each fetch, cleared (and buttons re-enabled) on failure so the
   user can retry, left set through the existing success hide-and-reload
   path, and also reset when a new bucket's dialog opens so an abandoned
   in-flight request from a closed dialog can't leave the buttons stuck
   disabled. Verified with jsdom: double-clicking Save now sends exactly
   one PUT, and a Delete click while that PUT is still pending sends no
   DELETE.

* admin: scope bucket-policy mutation completions to the bucket that started them

1. The previous round's fix reset bucketPolicyMutationInFlight whenever a
   new bucket's policy dialog opened, to avoid leaving Save/Delete stuck
   disabled if the modal was closed mid-request. That traded one bug for
   a worse one: if bucket A's PUT/DELETE was still in flight when the
   user opened bucket B's dialog, the reset let B's Save/Delete fire
   immediately, and A's completion handler - unaware anything had
   changed - would still hide the (now B's) modal and reload the page
   out from under whatever the user was doing with B, on success, or
   alert a message with no bucket context, on failure.

   Stop resetting on reopen, so a pending mutation for a previous bucket
   keeps this bucket's Save/Delete blocked until it settles (matches the
   "preventing overlapping mutations" the review comment describes).
   Instead, capture policyEditorBucket as targetBucket right before each
   fetch and compare it against policyEditorBucket again in the
   completion handler: the in-flight flag is always released so the
   buttons never get stuck, but the modal-hide/reload/alert only fire if
   this bucket is still the one showing; a stale completion for an
   abandoned bucket just logs to the console instead.

   Verified with a jsdom simulation: opening bucket B while bucket A's
   Save is still pending leaves B's Save button disabled and a click on
   it a no-op; once A's PUT resolves, B's button re-enables but no
   modal.hide()/reload() fires (previously both fired unconditionally).

2. bucketPolicyDeleteBtn had no bucketPolicyLoaded check, unlike Save -
   a failed GET blocked Save but left Delete free to remove a policy the
   client never actually saw (the same gap already fixed for the S3
   Tables policy modals in an earlier round). Added the same guard,
   ahead of the confirm() dialog. Verified with jsdom: Delete after a
   failed load now sends no DELETE request.

孙超 c80664ec21 s3: propagate storage rule fsync to volume server uploads (#10906)
The storage rule's fsync decision was computed by the filer
(detectStorageOption -> rule.Fsync) and applied on the filer's own HTTP
write path, but was never carried onto the chunk uploads S3 issues: the
AssignVolumeResponse had no fsync field, so the s3api client could not
learn the decision, and the chunked upload URL was hardcoded without it.
Every S3 write to a path with fsync configured went to the volume server
as a non-fsync write.

Carry the decision through the assign response:

- filer.proto: AssignVolumeResponse gains bool fsync, filled from the
  storage option the assign resolved.
- operation.AssignResult gains Fsync, so uploadChunk can append
  ?fsync=true to the volume server upload URL (single and replica
  fan-out paths).
- The S3 PUT/UploadPart assignFunc, the S3 copy path, the admin file
  browser upload, and the Iceberg worker assign functions all forward
  the response field.

Chris Lu 36c97344ef s3: confine a Lance catalog table location to the caller's own bucket (#10901)
The Lance namespace gateway took the request-body location field, trimmed a
trailing slash, and passed it straight to the marker sink. That location feeds
TableDataDirFromMetadataLocation, which joins it under /buckets and collapses
any ../ segments, and writeMarker's CreateEntry then auto-creates every missing
parent. A caller could point the location at another tenant's bucket, or escape
/buckets entirely, and plant a fixed-name marker (recursively creating the
parents) or hide a victim's live table with .lance-deregistered.

Confine the declared location the way the Iceberg gateway already does: require
an s3:// URI whose bucket is the caller's own and whose path carries no
traversal segment, on both the declare and register handlers.

s3api: no filer failover after fn has consumed part of a response

withFilerClientFailover replays fn verbatim on the next filer, so a filer
that died mid-stream followed by a healthy peer returned success with the
callback's closure-captured accumulator holding the dead filer's prefix
twice; the per-attempt accumulator in listWithRetry could not close this,
because the replay happens inside a single attempt. Track delivery on the
connection handed to fn: once a unary reply or streamed message has reached
the callback, surface the transport error unwrapped instead of failing
over, and let callers replay from a clean slate. A filer that fails before
delivering anything fails over exactly as before.

* s3api: retry a transient failure when listing multipart uploads/parts

A blip on the way to the filer failed the whole ListMultipartUploads or
ListParts request. Both reported failure points sit inside one streaming
listing: the ListEntries call that opens the stream, and the stream.Recv
calls that drain it. Neither retried, so a single Unavailable answer from
a filer that was restarting turned into a 500 for the S3 client.

Replay the listing instead, bounded to three attempts with a 100ms
backoff that doubles. Only a transient failure is replayed. A not-found
answer stays authoritative so the empty-list branch still works, and
every other error still reaches the client on the first attempt.

This is scoped to (*S3ApiServer).list rather than added inside
DoSeaweedListWithSnapshot, which mount, the shell and the other object
listings share, and where a retry after a partial stream would
re-deliver entries the callback had already seen. Within one call to
list, a replay is safe: it collects into a fresh slice each time, so it
can neither duplicate nor drop entries.

That guarantee does not extend past this function. withFilerClientFailover
already re-runs its callback against the next filer on any non-NotFound
error without resetting the caller's accumulator, so on a multi-filer
gateway a mid-listing failover can itself produce a duplicated result
with err == nil, independent of this change and not fixed by it. Noted
in the PR rather than silently left for someone to rediscover.

641fc8b031 admin: add visual iam policy editor (#10878)
* admin: add visual iam policy editor

Add a structured, tabbed editor (Editor / JSON) for creating and editing
IAM policies in the admin dashboard, alongside the existing raw-JSON
textarea:

- policies.templ: per-statement cards for Sid, Effect, Action, and
  Resource, with unmanaged fields (Principal, NotPrincipal, NotResource,
  Condition, or anything else) preserved verbatim in a per-statement
  "advanced fields" JSON box so nothing is lost on round-trip. Switching
  tabs commits and reparses in both directions. Restored the "Use Sample
  Policy" button, now filling both the structured editor and the JSON
  tab. The "Validate" button now calls the existing but previously
  unused POST /api/object-store/policies/validate endpoint instead of
  doing JS-only checks.
- Progressive Resource ARN autocomplete: suggests bucket names first,
  then once "bucket/" is typed, suggests bucket/* plus the bucket's
  direct subfolders, drilling down one path segment at a time as the
  user types further "/" characters.
- New GET /api/files/list-folders endpoint (file_browser_handlers.go)
  backing the folder autocomplete: wraps the existing file browser data
  function and returns just the subdirectory names as JSON, scoped to
  paths under /buckets.
- Action-name suggestions (datalist) for the Action field, sourced from
  the existing s3_constants.S3_ACTION_* constants plus new
  s3_constants.S3TABLES_ACTION_* constants (extracted from the s3tables
  operation dispatch switch) so the suggestion list can't drift from the
  strings the engines actually understand.
- policy_handlers.go: ValidatePolicy now accepts a statement with only
  NotResource set (previously required Resource), matching
  policy_engine.validateStatement and the fact the new editor makes such
  statements reachable from the UI.
- Tests: ValidatePolicy behavior, route registration for the policy API
  and the new list-folders endpoint, list-folders path scoping, and the
  action-suggestion list's shape.

* admin: fix XSS, cache poisoning, and cap overshoot in policy editor

Address code review findings on the IAM policy editor added in the
previous commit:

- policies.templ (displayPolicyDetails): escape every interpolated
  policy value (Sid, Effect, Action, Resource, policy name, and the raw
  JSON document) before assigning to innerHTML. Policy documents can
  come from other admins or an import, so an unescaped field could
  execute script when the "View" modal renders it.
- policies.templ (policyEditorStateToDoc): reject JSON arrays in a
  statement's "advanced fields" box, not just invalid JSON. `typeof []
  === 'object'` was true, so a JSON array was assigned to the statement;
  subsequent property assignments (Sid, Effect, ...) landed on the array
  object but JSON.stringify of an array only serializes numeric indices,
  silently dropping them.
- policies.templ (loadPolicyFolderNames): on a failed folder lookup,
  remove the cache entry instead of permanently caching the empty
  fallback, so a transient network/server error doesn't block retries
  for the rest of the page's lifetime.
- file_browser_handlers.go (ListFolders): stop appending directory
  names as soon as the running count reaches maxListFoldersEntries,
  instead of only checking the cap after a full page is processed,
  so the returned list never exceeds the configured cap.

* admin: stop policy editor from clobbering the active tab and dropping malformed advanced fields

Address two review findings on the IAM policy editor (Issue 3, stored-XSS
in displayPolicyDetails, was already fixed by the previous commit and is
unchanged here):

- createPolicy, updatePolicy, and validatePolicyDocument always committed
  the structured editor's (possibly stale) state into the JSON textarea
  before submitting, even when the user had just edited the JSON tab
  directly. That silently discarded the user's JSON edits and
  validated/saved the old structured-editor state instead, which could
  leave broader permissions in force than intended.

  Added commitPolicyActiveTab(which), which commits whichever tab is
  currently visible into the other side instead of unconditionally
  overwriting the JSON tab from the editor: if the JSON tab is active it
  parses that JSON back into the structured editor (without touching the
  textarea itself), otherwise it serializes the structured editor into
  the textarea as before. All three call sites, plus the JSON-tab
  "show.bs.tab" handler, now use this and abort with an alert if the
  currently active tab's content can't be committed.

- policyEditorStateToDoc silently continued with an empty object when a
  statement's "advanced fields" box held invalid JSON, so switching
  tabs, validating, or saving would drop Principal/NotResource/Condition
  from that statement without telling the user. It now throws (with the
  statement number and parse error) on invalid or non-object JSON there,
  and callers surface that via showAlert and abort instead of proceeding.

* admin: keep unmanaged top-level policy fields across editor tab switches

policyDocToEditorState only carried Version and Statement into editor
state, so any other top-level key (e.g. Id) present in the JSON tab was
silently rewritten away as soon as the user switched to the Editor tab
and back. Capture those keys in state.otherFields and merge them back in
policyEditorStateToDoc before Version and Statement are written, so the
two tabs stay faithful to each other and the editor never rewrites text
the user typed.

Note this is editor fidelity only: the admin API's
policy_engine.PolicyDocument carries just Version and Statement, and
DocumentJSON is never populated, so such fields are still discarded by
the server once a policy is saved. Making them survive a save would
require a backend change, which is out of scope here.

* admin: warn before a policy save discards unsupported top-level fields

The editor round-trips unmanaged top-level keys (e.g. Id) between the
Editor and JSON tabs, but the admin API's policy_engine.PolicyDocument
carries only Version and Statement, so the server drops them on save and
the user saw no indication.

Added confirmPolicyFieldDiscard(), called from createPolicy and
updatePolicy after the active tab is committed (so the field list is
accurate whichever tab is showing). It names the fields that will be
lost and lets the user confirm or cancel. Not wired into
validatePolicyDocument, which doesn't persist anything.

Chose the warning over the alternative of persisting these fields
through the backend: policy_engine.PolicyDocument is shared by the S3
bucket-policy engine and IAM evaluation, so extending it would change
the stored document shape for every policy in the codebase - far beyond
the scope of this editor.

* admin: reject malformed Effect and Resource/NotResource conflicts in policy editor

Two review findings on the IAM policy editor:

- policyDocToEditorState defaulted any non-"Deny" Effect (missing,
  misspelled, wrong case) to "Allow". A statement meant to be "Deny" with
  a typo like "deny" would silently become a permissive "Allow" instead
  of being rejected. It now throws on anything but an exact "Allow" or
  "Deny", naming the offending statement and value.
  commitPolicyTextareaToEditor catches this the same way it already
  catches invalid JSON: alert the user and keep the JSON tab active
  instead of switching to the Editor tab with wrong data.

- policyEditorStateToDoc could save a statement with both Resource (from
  the structured field) and NotResource (surviving in the "advanced
  fields" extras from before the user switched to using Resource) set at
  once - a contradictory combination neither the admin's ValidatePolicy
  handler nor policy_engine's evaluator rejected. When the structured
  Resource field is non-empty it now deletes any leftover NotResource
  from extras, consistent with the file's existing rule that structured
  fields take precedence over extras. Mirrored the existing
  Principal/NotPrincipal exclusivity check in
  weed/admin/handlers/policy_handlers.go's ValidatePolicy to reject the
  same combination server-side, since create/update perform no
  validation at all. Deliberately left policy_engine.validateStatement
  (used by the S3 bucket-policy PUT handler for every bucket policy in
  the product) unchanged - extending that shared validator is a larger,
  separate change outside this admin-editor fix's scope.

Added a handler test for the new Resource+NotResource rejection.

* admin: add NotResource support to the visual policy editor

Since Resource and NotResource are mutually exclusive (enforced by a
previous fix), NotResource could previously only be set through the raw
JSON in a statement's "advanced fields" box. Promote it to a first-class
mode of the structured editor:

- The static "Resources" label is now a Resource/NotResource dropdown;
  the same list of values underneath is reused for either key depending
  on the selected mode, with a short form-text explaining the semantics.
- NotResource is added to POLICY_STATEMENT_KNOWN_KEYS, since it's now a
  managed field like Resource rather than something that falls through
  to extras.
- policyDocToEditorState derives resourceMode from which key is present
  on load, and throws (same handling as the existing malformed-Effect
  case: alert, keep the JSON tab active) if a hand-edited document has
  both Resource and NotResource on one statement, since that can't be
  represented by the dropdown.
- policyEditorStateToDoc writes only the key matching the selected mode,
  replacing the previous one-directional "delete NotResource whenever
  Resource is set" fix with mode-driven logic that also deletes Resource
  when NotResource is selected.
- displayPolicyDetails (the read-only View modal) now shows the actual
  NotResource values with a distinct label instead of a static
  "(NotResource used instead)" placeholder.

No backend changes: the server-side "cannot specify both" check added
previously in policy_handlers.go's ValidatePolicy already covers this.

* admin: reject non-object policy documents; catch Principal/NotPrincipal conflicts server-side

Two review findings:

- policyDocToEditorState treated a top-level JSON value that wasn't an
  object (null, or a bare string/number/boolean) as an empty statement
  list instead of failing explicitly. If the user typed e.g. "hello" or
  42 in the JSON tab and switched to the Editor tab, their input was
  silently discarded and replaced with an empty policy - the same class
  of "guess instead of reject" bug fixed for malformed Effect and
  Resource/NotResource conflicts previously. Added an explicit check
  that throws for null/scalar input, while leaving array and object
  document shapes accepted exactly as before.

- weed/admin/handlers/policy_handlers.go's ValidatePolicy checked the
  Resource/NotResource conflict by non-empty length
  (len(...Strings()) > 0), which misses a statement where Resource is
  explicitly present but an empty list (e.g. "Resource": []) alongside a
  non-empty NotResource. Switched that check to field presence (!= nil),
  matching how policy_engine's own validateStatement already treats
  Principal/NotPrincipal exclusivity. Also added the equivalent
  Principal/NotPrincipal presence check to this handler, which had none
  before - the advanced-fields box in the visual editor lets a user set
  both today, and nothing server-side caught it. The existing
  non-empty "Resource or NotResource is required" check is left as a
  length check, since an empty array shouldn't count as "provided".

Added test cases for both conflict checks in policy_handlers_test.go.

* admin: add Principal/NotPrincipal support to the visual policy editor (v1, AWS-only)

Adds a first, deliberately narrow structured editor for a statement's
Principal/NotPrincipal, left out when NotResource support was added:

- A Principal/NotPrincipal mode dropdown mirrors the existing
  Resource/NotResource one (same mutual-exclusivity handling: the two
  fields can't be set at once, and switching modes reuses the same
  value list).
- A simple repeatable text-value list feeds a single {"AWS": [...]}
  object on save - always the AWS type, never the "bare" (untyped)
  SeaweedFS-extension shape. Per policy_engine's allowedPrincipalKeys,
  Service/Federated/CanonicalUser also parse successfully, but nothing
  in the S3 bucket-policy evaluation path ever sets a real caller's
  principal to a service name, an OIDC provider ARN, or a canonical
  user ID, so only AWS is functionally meaningful today - out of scope
  for this v1.
- On load, only the exact {"AWS": ...} single-key shape is unwrapped
  into the structured field and removed from "extras". Anything else
  (bare string/array, a different single type key, or several type
  keys at once) is left untouched in "extras" exactly as before, with a
  visible warning under the dropdown so the user knows a
  Principal/NotPrincipal exists but isn't shown there. Saving with the
  structured field left empty never touches whatever's already in
  extras, so a preserved complex form isn't silently dropped just
  because the user didn't touch this field.
- The read-only View modal now displays Principal/NotPrincipal for any
  shape (via a small generic summarizer), not just the AWS-simple one.
- Generalized the action/resource field-to-state-key mapping (used by
  commitPolicyEditorForm and the add/remove-item click handler) into a
  shared lookup table instead of stacking another ternary, now that a
  third field (principal) exists.

Regenerated policies_templ.go with the already-stamped templ v0.3.1001.

* admin: support the bare "*" wildcard Principal in the visual editor

"Principal": "*" (and NotPrincipal: "*") is the standard AWS shorthand
for "everyone" and is common in real bucket policies, but the v1
Principal/NotPrincipal editor only recognized the {"AWS": ...} object
form, leaving a bare "*" statement's principal hidden in Advanced
fields.

parseSimpleAwsPrincipal now also accepts the bare string "*" as a
simple, structurally-editable value. On save, a principal value list
containing exactly ["*"] is written back as the bare "*" string
(matching the common convention) rather than wrapped as {"AWS": "*"};
anything else still wraps under AWS as before. Updated the field's
form-text hint accordingly.

* admin: add Principal field autocomplete backed by users + IAM roles

Adds a datalist-backed autocomplete for the policy editor's Principal/
NotPrincipal text fields, sourced from a new API listing existing
identities:

- weed/admin/dash/principal_suggestions.go: AdminServer.GetPrincipalSuggestions
  combines S3 user ARNs (via the existing GetObjectStoreUsers +
  iam.UserArn) with IAM role ARNs (via integration.NewFilerRoleStore /
  ListRoles, reusing the exact same construction already used in
  iam_manager.go - no new dependency risk introduced). Role ARNs are
  reconstructed from the role name using SeaweedFS's default
  arn:aws:iam::role/<name> convention rather than fetching each role's
  stored definition, since this only backs a suggestion list. Role
  listing failures are logged and swallowed rather than failing the
  whole request - an incomplete suggestion list is fine, blocking
  policy editing over it is not. Service accounts are deliberately not
  listed separately: a service account's ARN is identical to its parent
  user's, already covered by the user list.
- weed/admin/handlers/policy_handlers.go: GetPrincipalSuggestions handler
  exposing this as {"principals": [...]}.
- Route registered at the API root (GET /api/principals) rather than
  under policyApi's "/object-store/policies" prefix, since that
  subrouter's existing "/{name}" GET route would shadow any
  single-segment GET route registered after it (the same class of
  gotcha previously seen with "/validate").
- weed/admin/view/app/policies.templ: a shared, lazily-fetched-once
  policyPrincipalSuggestions datalist (flat list - unlike the
  progressive per-folder Resource ARN autocomplete, users/roles aren't
  hierarchical), wired into policyListRowHtml for field:"principal" and
  populated on input/focus, with "*" always offered first.

Added tests for the new ARN-construction helper and route registration.

* admin: fix fieldset/legend styling in the structured policy editor

Bootstrap's form reset stretches <legend> to the fieldset's full width
(float: left; width: 100%), which loses the native "notch in the
border" look and makes each section's label bar as wide as the card.

Add two scoped classes: .policy-stmt-fieldset (border, rounded
corners, spacing between sections) and .policy-stmt-legend (undoes the
float/width so the legend hugs its content, with a little padding).
Applied to the three per-statement sections (Actions,
Resource/NotResource, Principal/NotPrincipal), replacing the ad hoc
"border rounded" utility classes that were doubling up with the
fieldset's own border. Also gave the "Advanced fields" <details> a
small top margin to match the new spacing.

* admin: suggest bucket/* alongside the bucket itself in Resource autocomplete

At the bucket-name stage of the Resource field's progressive
autocomplete, only "arn:aws:s3:::bucket" was offered. Add
"arn:aws:s3:::bucket/*" right alongside it, since granting access to
everything in a bucket is the more common case and previously required
typing a "/" first to reach the folder-level "*" suggestion.

* admin: keep an unparseable policy in the JSON tab instead of wiping it

editPolicy() built the structured state inside the fetch .then, so a
policy the editor cannot model threw into the sibling .catch, which
alerted and called hide(). Showing the alert at that moment left the
modal on screen with an empty editor and the document only in the JSON
tab, and Save Changes then serialized the empty state over the policy.

Reachable two ways, since neither create path rejects these: the admin
API never validates on create, so "Effect":"allow" is stored as typed,
and policy_engine.validateStatement lets Resource and NotResource sit
in the same statement.

Hand the document to the JSON tab instead, which is what that tab is
for, and mark the state so nothing serializes the placeholder over it.

* admin: validate a policy document before saving it

Validation was wired only to the Validate button, so nothing stopped a
document the server's own validator rejects from being stored. With the
structured editor supplying the boilerplate and required dropped from
the textarea, opening the modal, typing a name and clicking Create
Policy was enough to save a statement-less policy.

Share validatePolicyJSON with the two save paths and abort on failure.

* admin: bound the folder autocomplete listing

maxListFoldersEntries caps the folders collected, but nothing capped the
entries paged through to find them, so a bucket holding only flat object
keys - no subfolders to count - was walked to the end, 200 entries per
round trip, behind one keystroke. Measured against an in-process filer:
6 entries 0.5ms, 3k entries 7.7ms, 30k entries 53ms, all of it linear in
the directory rather than in the answer.

Cap the scan as well, and let GetFileBrowser take a prefix so the segment
the user is still typing is filtered by the filer instead of by paging.
The same 30k directory now answers in 0.6ms once a prefix is typed.

* admin: clean the path before scoping list-folders to /buckets

util.CleanWindowsPath only rewrites backslashes, so "/buckets/../etc"
walked straight past the prefix check the endpoint relies on for its
scope. Nothing leaked - filer paths are literal keys, so the traversal
resolved to nothing - but the check reads as a boundary and wasn't one,
and the test asserting it didn't cover the one input that would try.

validateAndCleanFilePath in the same file already does this.

* admin: stringify policy values before escaping them

escapeHtml calls text.replace directly, and the Sid, the per-item action
and resource inputs, and the View modal's Resource/NotResource all pass
values straight out of JSON.parse. A policy carrying "Sid": 5 or
"Action": [1] threw "text.replace is not a function" and took the render
with it. escapedJoin already coerced; use it everywhere and coerce the
editor state at the point it's built.

* admin: only show the NotResource hint in NotResource mode

The hint rendered unconditionally, so it sat under a selector reading
"Resource" telling the user the statement applies to everything except
what they'd listed. Redraw the card when the selector changes so it
follows the mode.

* 14850

* filer: stamp the content MD5 on every SaveInsideFiler write

An entry's ETag falls back to Attributes.Md5, so conditional writers key
IF_ETAG_MATCH off it. SaveInsideFiler carried the looked-up attributes
forward without refreshing the hash, leaving it describing whatever the
previous writer stored: a later conditional write matched the stale hash
and overwrote content that had already changed.

* s3api: give the bucket lifecycle constants and the write route key one definition each

The extended-attribute keys, the XML size cap and the object-write ring key
prefix were each spelled out in two places, so the admin dashboard's copies
could drift from the gateway's. Move them to the packages both sides already
import and alias them where the short local name reads better.

* admin: patch the bucket entry's lifecycle keys instead of rewriting the entry

The save read the bucket entry, edited its extended map and wrote the whole
entry back, guarded by IF_UNMODIFIED_SINCE. Nothing that writes a bucket
entry advances its mtime - not the S3 gateway's patchBucketEntry, not
SetBucketOwner, not SetBucketQuota - so the guard never fired and the stale
snapshot reverted whatever else had changed since the lookup.

Send the PATCH_EXTENDED mutation the S3 gateway already uses for these keys:
the filer re-reads and merges under the bucket path lock, so only the two
lifecycle keys move. That removes the reason for the mtime snapshot, the
verification retry loop and the compensating restore of the cleared day-TTL
rules, which the migration now logs instead.

* s3api: run the delete-lifecycle day-TTL migration through the shared helper

DeleteBucketLifecycleHandler kept its own copy of the read-strip-write
sequence the put handler now shares, including a missing return that let a
ToText failure persist a truncated filer.conf and write a second response.
It also wrote the whole file back unconditionally, reverting any concurrent
edit; the shared helper writes conditionally.

* admin: answer 404 when a lifecycle request names a bucket that does not exist

Every SetBucketLifecycle failure came back as 500, including the lookup miss
for an unknown bucket, so a client or monitor read a caller error as a server
fault and retried it.

* s3api: emit lifecycle XML a client would recognize

Two changes to what MarshalCanonical writes, both visible through
GetBucketLifecycleConfiguration, which replays the stored bytes verbatim:
stamp the S3 namespace on the root, and put a size range under <And>. A
<Filter> carries one predicate, so two size bounds side by side is a shape
AWS does not document. Parsing still accepts either.

* admin: fix the lifecycle editor's handling of stored status, deletes and empty saves

Four things the editor got wrong:

A stored <Status> the S3 API never validated, say 'enabled', left both radio
buttons unchecked, so reading the form threw on a null querySelector result
and Save did nothing. Collapse anything but an exact 'Enabled' to 'Disabled',
which is what the engine already does with it.

Deleting a rule re-rendered an open edit form from the snapshot taken when
editing began, discarding what had been typed; every other transition folds
the form in first.

The Transition warning only matched a bare <Transition>, missing the form
with attributes, self-closed or namespace-prefixed.

Saving an emptied rule list clears the configuration through a path with no
prompt, next to a Delete-all-rules button that asks.

Also collapses the three divergent copies of formatBytes on this page to one.

* filer: stop the day-TTL migration from deleting an operator's path rule

The migration removed every rule under the bucket's path that carried a day
TTL in the bucket's collection. The add path it is retiring used
AddLocationConf, which merged its TTL onto whatever already sat at the
prefix, so a rule can hold operator settings the lifecycle path never wrote -
a disk type, WORM retention, a read-only flag, a placement pin. Deleting the
whole rule to retire its TTL took those with it, leaving objects under that
prefix on defaults nobody asked for.

Delete only rules shaped like ones the add path created from scratch;
anything else keeps its settings and loses just the TTL.
