Chris Lu 7bb0a1c127 s3: replay a delete whose reply the transport dropped (#11022)
* s3: stop retrying a delete the filer refused for a non-empty folder

The filer looked and the children are there, so the answer will not change.
retryFilerOp spent six attempts and up to 3.1s of backoff on it before the
caller could act on the condition it was already holding.

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.

* s3: share one retry allowance across multipart completion cleanup

The unused-entry loop deletes once per entry, and each delete now retries,
so a filer that stays unavailable held the response for 3.1s per entry after
the object was already committed.

Chris Lu 742b2f5896 s3: share one retry allowance across a batch delete (#11001)
Every key in a multi-object delete drives its own retryFilerOp, so a filer
that is briefly unhealthy multiplied one op's ~3.1s of backoff by a key
count the client picks. The batch now carries a single allowance in its
context, sized to one op's worst case; once it is spent the remaining keys
fail fast with a per-key error instead of holding the request goroutine.
A single-object delete carries no allowance and keeps its full retries.

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 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 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 2d9ea0285c s3: add the RenameObject endpoint (#10659)
* s3: add the RenameObject endpoint

PUT /{bucket}/{key}?renameObject with x-amz-rename-source moves an object
through the filer's AtomicRenameEntry, so no bytes are read or rewritten and
the ETag, tags and SSE keys travel with the entry.

Only unversioned buckets: a versioned rename would have to rebuild the
.versions chain, and AWS offers RenameObject on directory buckets, which
cannot be versioned. The source arrives in a header, so it is authorized
separately for read and delete; both keys are locked, in key order, across the
precondition checks and the move.

* s3: let a matched source ETag precondition settle its date precondition

RFC 7232 has an ETag precondition outrank the date precondition on its own
side, and AWS documents the same for CopyObject: a matching
x-amz-copy-source-if-match with a failing x-amz-copy-source-if-unmodified-since
copies rather than returning 412. The source check evaluated all four headers in
sequence, so the date header could still veto a decided ETag match.

validateConditionalHeadersForReads already applies this precedence; the source
path now matches it.

* s3: cover a rename source named as a directory without a trailing slash

Renaming a directory would move a whole subtree, so it has to stay a missing
key whether or not the caller wrote the trailing slash.

* s3: accept a bare object key as the RenameObject source

AWS spells x-amz-rename-source both ways. Its CLI, Java and Rust examples pass
the bare source key, and only a second CLI example and the boto3 conditional
example pass bucket/key; the API reference's own example is a bare key too. The
header was read as bucket/key only, so the form AWS leads with was rejected with
InvalidArgument and the endpoint was unusable as documented.

A value is now read as a literal key first — the only reading that can never
name the wrong object — and as bucket-qualified second, when it carries the
request's own bucket and the literal key does not exist. That costs one extra
lookup only for a source that starts with the bucket's own name.

Another bucket's name in the source is no longer a distinct error: RenameObject
moves within one bucket, so it is simply part of a key this bucket does not
hold, and it reports NoSuchKey.

* s3: only a proven absence picks the other reading of a rename source

A source that resolves to a directory is not a miss to fall through on: the
literal path is still what the caller named, so answering for it beats renaming
a different object under the bucket-qualified reading. With a directory at
bucket/source.txt and an object at source.txt, a rename naming the former moved
the latter.

A failed lookup is not a proof of absence either, so a blip can no longer
redirect a rename to the other reading.

Chris Lu 7d6c83b126 s3: stop treating a directory marker as a versioned object (#10573)
* s3: delete a directory marker instead of versioning it

The key "dir/" is stored as the filer directory itself, so a delete marker
cannot stand in for it without hiding the children underneath, and its history
has to sit inside the directory it describes, where listings keep meeting it.
Delete it the way an unversioned bucket already does: remove the directory
when nothing is left under it, demote it to a plain directory when children
remain, and drop a history an older build recorded for it.

* s3: stop resolving directory markers through a version history

Nothing records one for them any more, so the lookups that read it are dead
weight - and the one in the listing was a filer round trip per directory
marker returned, which for a bucket that keeps a marker per directory is the
whole listing cost. A listing reads what a directory stands for straight off
the entry it already has; a unit test pins that N markers cost one ListEntries
rather than N+1. The guard that keeps a history left inside a directory by an
older build from surfacing as a key named after it stays.

* s3: do not let deleting "dir/" destroy the object at "dir"

Writing under an existing object turns that object's entry into a directory
while it keeps its data, so the keys "m2" and "m2/" end up sharing one entry.
Stripping the entry to delete "m2/" therefore wiped the object at "m2" - a
different key, and in a versioned bucket one no delete marker records. Leave a
directory holding uploaded data alone; "m2/" does not name it.

* s3: make the directory-marker delete fail closed and take the write lock

The guard that spares a promoted file only fired when the entry read
succeeded, so a transient filer error fell through to the delete and could
destroy the object at "dir" anyway. Fail the request instead, take the object
write lock so the entry cannot change between the check and the delete, and
report a stale history that cannot be removed rather than leaving it to keep
naming the key in ListObjectVersions.

* s3: check If-Match inside the directory-marker delete lock

The lock belongs to the caller: taking it inside the delete nested it under the
batch handler's own lock, and since every lock from a gateway shares one owner
the inner release would have freed it while the outer caller still assumed it
held it. Both callers now own the lock, the single-object path re-checks
If-Match inside it the way the other delete paths do, and a batch delete of a
trailing-slash key in an unversioned bucket goes through the same marker path
instead of the raw delete. A history lookup that fails now fails the delete.

Chris Lu 0345658ea8 [s3] validate indirect filer path inputs (#9931)
* s3: validate indirect filer path inputs

* s3: avoid query parsing on common request path

* filer: scope copy/move source against JWT AllowedPrefixes

maybeCheckJwtAuthorization only checked r.URL.Path, but copy and move read
their source from the cp.from / mv.from query params. A prefix-restricted
token could copy or move data out of a subtree it cannot otherwise reach.
Check every path the request touches, reusing pathHasComponentPrefix so
`..` in the source is collapsed before the prefix match.

* s3: confine iceberg CreateTable location to the catalog bucket

CreateTable derived the metadata bucket and path from the client-supplied
req.Location / req.Name and wrote there directly, so a caller scoped to one
table bucket could place metadata in another bucket (and path.Join collapsed
any `..`). Require the parsed bucket to equal the request's catalog bucket
and reject traversal segments in the table path.

* webdav: clean client path before subFolder confinement

wrappedFs concatenated subFolder + name before the underlying FileSystem
ran path.Clean, so `..` in the request path or COPY/MOVE Destination
resolved across the FilerRootPath confinement boundary. Clean the name as a
rooted path first so traversal segments collapse below subFolder. Only the
non-default -filer.path (non-empty subFolder) setup was affected.

* filer: enforce read-only rule on real write path with destination header

The x-seaweedfs-destination header overrides the path used for storage-rule
matching while the entry is written at r.URL.Path, letting a caller select a
writable rule for a read-only target. When the header is present, also check
the read-only/quota rule against the actual write path.

Chris Lu d321f9efb4 s3: collapse suspended-versioning deletes onto one null marker (#9845)
A suspended-versioning DELETE was recorded with createDeleteMarker, which mints a
fresh real version id each time, so repeated suspended deletes piled up delete
markers instead of overwriting a single null marker as S3 specifies. Record the
suspended delete as a 'null' marker with a fixed file name (v_null) and point the
latest-version pointer at it explicitly; putSuspendedVersioningObject's existing
null-version cleanup removes it on the next suspended PUT, so the object undeletes
cleanly and at most one null marker exists. Enabled-versioning deletes are
unchanged (still distinct historical markers).

Update TestSuspendedVersioningDeleteBehavior to the AWS-correct counts: one null
marker after a suspended delete, and the null marker plus one real marker after a
re-enabled delete.

Chris Lu 8e4022d5c7 fix(s3api): authorize DeleteObjects per key so object-scoped policies match (#9793)
Bulk DeleteObjects carries the keys in the request body, so the route Auth
middleware ran a single bucket-level check with object="", building the
resource ARN as arn:aws:s3:::<bucket>. That never matches an s3:DeleteObject
policy scoped to <bucket>/*, so the entire batch was denied even though the
single-key DELETE worked with the same credentials.

Defer authorization to the handler and check each key via AuthorizeBatchDeleteKey,
mirroring AuthorizeCopySource: a synthetic DELETE /<bucket>/<key> request resolves
s3:DeleteObject (or s3:DeleteObjectVersion when a versionId is given) against the
object ARN. Denied keys come back as per-key errors while authorized keys still
delete, matching AWS semantics.

Chris Lu fa7056dc6f s3: route object-lock version-specific deletes off the distributed lock (#9657)
A version-specific DELETE (real version or the null version, including
object-lock WORM-checked ones and governance-bypass) now runs as one routed
transaction on the object's owner instead of holding the distributed lock.

For a real version: recompute the .versions pointer excluding the version
(repoint-before-delete, so a crash leaves a recoverable orphan rather than a
dangling pointer), then delete the version file, under the object's per-path lock.
The null version is the regular object entry, deleted directly (no pointer).

Object-lock buckets gate the delete on the version's WORM guards evaluated on the
owner: legal hold (always) + retention (while not elapsed). Governance bypass
scopes the retention guard to COMPLIANCE mode, so the filer allows a
governance-mode delete while still denying compliance and legal hold — the
gateway never reads the version.

Three primitives make this expressible:
- ObjectTransaction.condition_key: evaluate the condition against a named entry
  (the version) while the lock stays on lock_key (the object).
- Recompute.exclude_name: omit a child from the scan, to repoint before delete.
- WriteCondition.Clause gate_key/gate_value: scope IF_EXTENDED_TIME_ELAPSED to a
  mode, expressing governance bypass without a gateway-side read.

Chris Lu 4b9d46b5ad s3: route versioned COPY and delete-marker off the DLM (#9633)
s3: route versioned/suspended delete markers and versioned COPY off the lock

createDeleteMarker flips the .versions pointer via routedVersionedFinalize
(RECOMPUTE_LATEST on the owner filer) when an owner is known, so an Enabled or
Suspended DeleteObject takes its pointer flip off the distributed lock; the
delete marker file is written first and the owner re-derives the pointer.

DeleteObjectHandler routes a versioned/suspended delete with no specific version
straight to the owner, off the lock. A specific-version delete and object-lock
buckets keep the lock (the former needs a recompute-after-delete handled
separately; the latter needs gateway-side enforcement).

CopyObject into a versioned bucket finalizes the new version through the same
routed pointer flip.

Chris Lu f9bc6adf98 s3: route single-entry object writes to the owner filer, off the DLM (#9629)
s3: route non-versioned object PUT and DELETE off the distributed lock

A non-versioned, non-object-lock object write now goes straight to the key's
owner filer as a single-mutation ObjectTransaction, which serializes it with the
owner's per-path lock and evaluates the precondition, instead of taking a
cluster-wide lock. PUT and DELETE use the object's full path as the lock key, so
a concurrent create and delete of the same key serialize against each other.

The fast path is taken only when the precondition reduces to clauses the filer
can evaluate (existence and a single strong-ETag match); time-based conditions,
ETag lists, weak ETags, post-create hooks, and an unknown owner fall back to the
lock. A routed mutation error other than a failed precondition also falls back,
so the lock path stays the authority for the cases it alone covers.

PrimaryForKey returns "" until the ring view arrives, keeping writes on the lock
until routing is known.

Chris Lu 79859fc21d feat(s3/versioning): grep-able heal logs + scan-anomaly diagnostics + audit cmd (#9468)
* feat(s3/versioning): grep-able heal logs + scan-anomaly diagnostics + audit cmd

Three diagnostic additions on top of #9460, all aimed at making the next
production incident faster to triage than the one we just spent hours on.

1. [versioning-heal] grep prefix on every heal-related log line, with a
   small fixed event vocabulary (produced / surfaced / healed / enqueue /
   drain / retry / gave_up / anomaly / clear_failed / heal_persist_failed
   / teardown_failed / queue_full). One grep gives operators a single
   event stream across the produce-to-drain lifecycle.

2. Escalate the "scanned N>0 entries but no valid latest" case in
   updateLatestVersionAfterDeletion from V(1) Infof to a Warning that
   names the orphan entries it saw. This is the listing-after-rm
   inconsistency signature that pinned down 259064a8's failure — it
   should not be invisible at default log levels.

3. New weed shell command `s3.versions.audit -prefix <path> [-v] [-heal]`
   that walks .versions/ directories under a prefix and reports the
   stranded population. With -heal it clears the latest-version pointer
   in place on stranded directories so subsequent reads return a clean
   NoSuchKey instead of replaying the 10-retry self-heal loop.

* fix(s3/versioning): audit pagination, exclusive categories, ctx-aware retry

Address PR review:

1. s3.versions.audit walked only the first 1024-entry page of each
   .versions/ directory, false-positiving "stranded" on large dirs.
   Loop until the page returns < 1024 entries, advancing startName.

2. clean and orphan-only categories double-counted when a directory
   had no pointer and at least one orphan: incremented both. Make them
   mutually exclusive so report totals sum to versionsDirs.

3. retryFilerOp's worst-case ~6.3s backoff was a bare time.Sleep,
   non-interruptible by ctx. A server shutdown / client disconnect
   would wait out the budget per in-flight delete. Thread ctx through
   deleteSpecificObjectVersion -> repointLatestBeforeDeletion /
   updateLatestVersionAfterDeletion -> retryFilerOp; backoff now uses
   a select{<-ctx.Done(), <-timer.C}. HTTP handlers pass r.Context();
   gRPC lifecycle handlers pass the stream ctx.

   New test pins the behavior: cancelling ctx mid-backoff returns
   ctx.Err() in <500ms instead of blocking ~6.3s.

* fix(s3/versioning): clearStale outcome + escape grep-able log fields

Two coderabbit follow-ups:

1. Successful pointer clear should suppress `produced`.
   updateLatestVersionAfterDeletion's transient-rm fallback called
   clearStaleLatestVersionPointer best-effort, then unconditionally
   returned retryErr. The caller (deleteSpecificObjectVersion) saw the
   error and emitted `event=produced` + enqueued the reconciler, even
   though clearStaleLatestVersionPointer had just driven the pointer to
   consistency and the next reader would get NoSuchKey via the
   clean-miss path. Make clearStaleLatestVersionPointer return cleared
   bool; on success the caller returns nil so neither produced nor the
   reconciler enqueue fires. Concurrent-writer aborts, re-scan errors,
   and CAS mismatches still report false so genuinely stranded state
   keeps surfacing.

2. Escape user-controlled fields in heal log lines.
   versioningHealInfof / Warningf / Errorf interpolated raw bucket /
   key / filename / err text into a single-space-separated line. An S3
   key (or error string from gRPC) containing whitespace, newlines, or
   `event=...` could split one event into multiple tokens and spoof
   fake fields downstream. Sanitize each arg in the helper: safe
   values pass through; anything with whitespace, quotes, control
   chars, or backslashes is replaced with its strconv.Quote form. No
   caller changes — the format strings remain unchanged.

Tests pin both behaviors: sanitization table covers the field
boundary cases; an end-to-end shape test confirms a key containing
`event=spoof` stays inside a single quoted token.

Chris Lu 3f1eaf9724 fix(s3/audit): emit audit log for successful GET/HEAD (#9467)
* fix(s3/audit): emit audit log for successful GET/HEAD

Successful GET/HEAD object requests never produced a fluent audit entry
because those handlers write the response directly (streaming for GET,
WriteHeader for HEAD) and never reach a PostLog call site. The wiki
advertises GET as an audited verb, so the asymmetry surprises operators
who rely on the log for read-access auditing.

Move the safety net into the track() middleware: tag each request with
an audit-tracking flag, let PostLog/PostAccessLog (delete path) mark it,
and emit a single fallback entry after the handler returns when nothing
fired. The recorder's status flows into the fallback so the audit row
still reflects 200/206 vs 404 etc. No double logging for handlers that
already emit (write helpers, error paths, bulk delete).

Refs #9463

* fix(s3/audit): defensive nil checks on audit-tracking helpers

Address PR review: guard against nil request and nil *atomic.Bool stored
under the audit-tracking key. The conditions are unreachable today (the
key is private and we only ever store new(atomic.Bool)), but the checks
are free and keep the helpers safe if a future caller misbehaves.

* test(s3/audit): track() audit fallback coverage + stale comment cleanup (#9469)

test(s3/audit): cover track() fallback wiring + cleanup

Adds two unit tests in weed/s3api/stats_test.go that exercise the
audit-tracking flag set up by track(): one verifies the fallback path
fires when a handler writes the response directly (the GET/HEAD object
regression in #9463), the other verifies the flag is set when a handler
emits PostLog itself so the fallback is skipped.

To make the wiring observable without standing up fluent, PostLog now
marks the audit flag before short-circuiting on a nil Logger; production
behavior is unchanged (no logger, no posting) but the flag stays
consistent.

Also drops two stale comments in s3api_object_handlers.go that still
referenced proxyToFiler — that helper was removed when GET/HEAD started
streaming from volume servers directly.

Stacks on #9467.

Chris Lu bb0c7c779f feat(s3/lifecycle): metadata-only delete when entry TtlSec > 0 (Phase 2b) (#9390)
* refactor(s3): thread metadataOnly into delete helpers

Add a metadataOnly bool to deleteUnversionedObjectWithClient and
deleteSpecificObjectVersion. When true the helper sends IsDeleteData=
false to the filer's DeleteEntry RPC so per-chunk DeleteFile RPCs are
skipped — the volume server reclaims chunks on its own at TTL drop.
Non-lifecycle callers (DELETE handlers, batch delete) pass false to
preserve today's eager-chunk-delete behavior; only the lifecycle
handler in the next commit will pass true.

* feat(s3/lifecycle): metadata-only delete when entry TtlSec > 0

Per-write TTL stamping (PR 9377) sets Attributes.TtlSec on every
lifecycle-fitting entry. When the live entry the LifecycleDelete
handler fetched carries TtlSec > 0 the volume server is guaranteed
to reclaim chunks at TTL drop, so the filer can skip per-chunk
DeleteFile RPCs and just remove the entry record. lifecycleDispatch
now computes metadataOnly from the live entry and threads it through
the unversioned, suspended-null, and noncurrent/expired-marker delete
paths. createDeleteMarker is unaffected — it creates a marker, never
deletes chunks.

Chris Lu 5a0204310c Add Iceberg admin UI (#8246)
* Add Iceberg table details view

* Enhance Iceberg catalog browsing UI

* Fix Iceberg UI security and logic issues

- Fix selectSchema() and partitionFieldsFromFullMetadata() to always search for matching IDs instead of checking != 0
- Fix snapshotsFromFullMetadata() to defensive-copy before sorting to prevent mutating caller's slice
- Fix XSS vulnerabilities in s3tables.js: replace innerHTML with textContent/createElement for user-controlled data
- Fix deleteIcebergTable() to redirect to namespace tables list on details page instead of reloading
- Fix data-bs-target in iceberg_namespaces.templ: remove templ.SafeURL for CSS selector
- Add catalogName to delete modal data attributes for proper redirect
- Remove unused hidden inputs from create table form (icebergTableBucketArn, icebergTableNamespace)

* Regenerate templ files for Iceberg UI updates

* Support complex Iceberg type objects in schema

Change Type field from string to json.RawMessage in both IcebergSchemaFieldInfo
and internal icebergSchemaField to properly handle Iceberg spec's complex type
objects (e.g. {"type": "struct", "fields": [...]}). Currently test data
only shows primitive string types, but this change makes the implementation
defensively robust for future complex types by preserving the exact JSON
representation. Add typeToString() helper and update schema extraction
functions to marshal string types as JSON. Update template to convert
json.RawMessage to string for display.

* Regenerate templ files for Type field changes

* templ

* Fix additional Iceberg UI issues from code review

- Fix lazy-load flag that was set before async operation completed, preventing retries
  on error; now sets loaded flag only after successful load and throws error to caller
  for proper error handling and UI updates
- Add zero-time guards for CreatedAt and ModifiedAt fields in table details to avoid
  displaying Go zero-time values; render dash when time is zero
- Add URL path escaping for all catalog/namespace/table names in URLs to prevent
  malformed URLs when names contain special characters like /, ?, or #
- Remove redundant innerHTML clear in loadIcebergNamespaceTables that cleared twice
  before appending the table list
- Fix selectSnapshotForMetrics to remove != 0 guard for consistency with selectSchema
  fix; now always searches for CurrentSnapshotID without zero-value gate
- Enhance typeToString() helper to display '(complex)' for non-primitive JSON types

* Regenerate templ files for Phase 3 updates

* Fix template generation to use correct file paths

Run templ generate from repo root instead of weed/admin directory to ensure
generated _templ.go files have correct absolute paths in error messages
(e.g., 'weed/admin/view/app/iceberg_table_details.templ' instead of
'app/iceberg_table_details.templ'). This ensures both 'make admin-generate'
at repo root and 'make generate' in weed/admin directory produce identical
output with consistent file path references.

* Regenerate template files with correct path references

* Validate S3 Tables names in UI

- Add client-side validation for table bucket and namespace names to surface
  errors for invalid characters (dots/underscores) before submission
- Use HTML validity messages with reportValidity for immediate feedback
- Update namespace helper text to reflect actual constraints (single-level,
  lowercase letters, numbers, and underscores)

* Regenerate templ files for namespace helper text

* Fix Iceberg catalog REST link and actions

* Disallow S3 object access on table buckets

* Validate Iceberg layout for table bucket objects

* Fix REST API link to /v1/config

* merge iceberg page with table bucket page

* Allowed Trino/Iceberg stats files in metadata validation

* refactor: use bucket path helpers throughout S3 API

- Replace direct bucket path operations with helper functions
- Leverage centralized table bucket routing logic
- Improve maintainability with consistent path resolution

* fix: add table bucket cache and improve filer error handling

- Cache table bucket lookups to reduce filer overhead on repeated checks
- Use filer_pb.CreateEntry and filer_pb.UpdateEntry helpers to check resp.Error
- Fix delete order in handler_bucket_get_list_delete: delete table object before directory
- Make location mapping errors best-effort: log and continue, don't fail API
- Update table location mappings to delete stale prior bucket mappings on update
- Add 1-second sleep before timestamp time travel query to ensure timestamps are in past
- Fix CSV parsing: examine all lines, not skip first; handle single-value rows

* fix: properly handle stale metadata location mapping cleanup

- Capture oldMetadataLocation before mutation in handleUpdateTable
- Update updateTableLocationMapping to accept both old and new locations
- Use passed-in oldMetadataLocation to detect location changes
- Delete stale mapping only when location actually changes
- Pass empty string for oldLocation in handleCreateTable (new tables have no prior mapping)
- Improve logging to show old -> new location transitions

* refactor: cleanup imports and cache design

- Remove unused 'sync' import from bucket_paths.go
- Use filer_pb.UpdateEntry helper in setExtendedAttribute and deleteExtendedAttribute for consistent error handling
- Add dedicated tableBucketCache map[string]bool to BucketRegistry instead of mixing concerns with metadataCache
- Improve cache separation: table buckets cache is now separate from bucket metadata cache

* fix: improve cache invalidation and add transient error handling

Cache invalidation (critical fix):
- Add tableLocationCache to BucketRegistry for location mapping lookups
- Clear tableBucketCache and tableLocationCache in RemoveBucketMetadata
- Prevents stale cache entries when buckets are deleted/recreated

Transient error handling:
- Only cache table bucket lookups when conclusive (found or ErrNotFound)
- Skip caching on transient errors (network, permission, etc)
- Prevents marking real table buckets as non-table due to transient failures

Performance optimization:
- Cache tableLocationDir results to avoid repeated filer RPCs on hot paths
- tableLocationDir now checks cache before making expensive filer lookups
- Cache stores empty string for 'not found' to avoid redundant lookups

Code clarity:
- Add comment to deleteDirectory explaining DeleteEntry response lacks Error field

* go fmt

* fix: mirror transient error handling in tableLocationDir and optimize bucketDir

Transient error handling:
- tableLocationDir now only caches definitive results
- Mirrors isTableBucket behavior to prevent treating transient errors as permanent misses
- Improves reliability on flaky systems or during recovery

Performance optimization:
- bucketDir avoids redundant isTableBucket call via bucketRoot
- Directly use s3a.option.BucketsPath for regular buckets
- Saves one cache lookup for every non-table bucket operation

* fix: revert bucketDir optimization to preserve bucketRoot logic

The optimization to directly use BucketsPath bypassed bucketRoot's logic
and caused issues with S3 list operations on delimiter+prefix cases.

Revert to using path.Join(s3a.bucketRoot(bucket), bucket) which properly
handles all bucket types and ensures consistent path resolution across
the codebase.

The slight performance cost of an extra cache lookup is worth the correctness
and consistency benefits.

* feat: move table buckets under /buckets

Add a table-bucket marker attribute, reuse bucket metadata cache for table bucket detection, and update list/validation/UI/test paths to treat table buckets as /buckets entries.

* Fix S3 Tables code review issues

- handler_bucket_create.go: Fix bucket existence check to properly validate
  entryResp.Entry before setting s3BucketExists flag (nil Entry should not
  indicate existing bucket)
- bucket_paths.go: Add clarifying comment to bucketRoot() explaining unified
  buckets root path for all bucket types
- file_browser_data.go: Optimize by extracting table bucket check early to
  avoid redundant WithFilerClient call

* Fix list prefix delimiter handling

* Handle list errors conservatively

* Fix Trino FOR TIMESTAMP query - use past timestamp

Iceberg requires the timestamp to be strictly in the past.
Use current_timestamp - interval '1' second instead of current_timestamp.

Chris Lu 2f6aa98221 Refactor: Replace removeDuplicateSlashes with NormalizeObjectKey (#7873)
* Replace removeDuplicateSlashes with NormalizeObjectKey

Use s3_constants.NormalizeObjectKey instead of removeDuplicateSlashes in most places
for consistency. NormalizeObjectKey handles both duplicate slash removal and ensures
the path starts with '/', providing more complete normalization.

* Fix double slash issues after NormalizeObjectKey

After using NormalizeObjectKey, object keys have a leading '/'. This commit ensures:
- getVersionedObjectDir strips leading slash before concatenation
- getEntry calls receive names without leading slash
- String concatenation with '/' doesn't create '//' paths

This prevents path construction errors like:
  /buckets/bucket//object  (wrong)
  /buckets/bucket/object   (correct)

* ensure object key leading "/"

* fix compilation

* fix: Strip leading slash from object keys in S3 API responses

After introducing NormalizeObjectKey, all internal object keys have a
leading slash. However, S3 API responses must return keys without
leading slashes to match AWS S3 behavior.

Fixed in three functions:
- addVersion: Strip slash for version list entries
- processRegularFile: Strip slash for regular file entries
- processExplicitDirectory: Strip slash for directory entries

This ensures ListObjectVersions and similar APIs return keys like
'bar' instead of '/bar', matching S3 API specifications.

* fix: Normalize keyMarker for consistent pagination comparison

The S3 API provides keyMarker without a leading slash (e.g., 'object-001'),
but after introducing NormalizeObjectKey, all internal object keys have
leading slashes (e.g., '/object-001').

When comparing keyMarker < normalizedObjectKey in shouldSkipObjectForMarker,
the ASCII value of '/' (47) is less than 'o' (111), causing all objects
to be incorrectly skipped during pagination. This resulted in page 2 and
beyond returning 0 results.

Fix: Normalize the keyMarker when creating versionCollector so comparisons
work correctly with normalized object keys.

Fixes pagination tests:
- TestVersioningPaginationOver1000Versions
- TestVersioningPaginationMultipleObjectsManyVersions

* refactor: Change NormalizeObjectKey to return keys without leading slash

BREAKING STRATEGY CHANGE:
Previously, NormalizeObjectKey added a leading slash to all object keys,
which required stripping it when returning keys to S3 API clients and
caused complexity in marker normalization for pagination.

NEW STRATEGY:
- NormalizeObjectKey now returns keys WITHOUT leading slash (e.g., 'foo/bar' not '/foo/bar')
- This matches the S3 API format directly
- All path concatenations now explicitly add '/' between bucket and object
- No need to strip slashes in responses or normalize markers

Changes:
1. Modified NormalizeObjectKey to strip leading slash instead of adding it
2. Fixed all path concatenations to use:
   - BucketsPath + '/' + bucket + '/' + object
   instead of:
   - BucketsPath + '/' + bucket + object
3. Reverted response key stripping in:
   - addVersion()
   - processRegularFile()
   - processExplicitDirectory()
4. Reverted keyMarker normalization in findVersionsRecursively()
5. Updated matchesPrefixFilter() to work with keys without leading slash
6. Fixed paths in handlers:
   - s3api_object_handlers.go (GetObject, HeadObject, cacheRemoteObjectForStreaming)
   - s3api_object_handlers_postpolicy.go
   - s3api_object_handlers_tagging.go
   - s3api_object_handlers_acl.go
   - s3api_version_id.go (getVersionedObjectDir, getVersionIdFormat)
   - s3api_object_versioning.go (getObjectVersionList, updateLatestVersionAfterDeletion)

All versioning tests pass including pagination stress tests.

* adjust format

* Update post policy tests to match new NormalizeObjectKey behavior

- Update TestPostPolicyKeyNormalization to expect keys without leading slashes
- Update TestNormalizeObjectKey to expect keys without leading slashes
- Update TestPostPolicyFilenameSubstitution to expect keys without leading slashes
- Update path construction in tests to use new pattern: BucketsPath + '/' + bucket + '/' + object

* Fix ListObjectVersions prefix filtering

Remove leading slash addition to prefix parameter to allow correct filtering
of .versions directories when listing object versions with a specific prefix.

The prefix parameter should match entry paths relative to bucket root.
Adding a leading slash was breaking the prefix filter for paginated requests.

Fixes pagination issue where second page returned 0 versions instead of
continuing with remaining versions.

* no leading slash

* Fix urlEscapeObject to add leading slash for filer paths

NormalizeObjectKey now returns keys without leading slashes to match S3 API format.
However, urlEscapeObject is used for filer paths which require leading slashes.
Add leading slash back after normalization to ensure filer paths are correct.

Fixes TestS3ApiServer_toFilerPath test failures.

* adjust tests

* normalize

* Fix: Normalize prefixes and markers in LIST operations using NormalizeObjectKey

Ensure consistent key normalization across all S3 operations (GET, PUT, LIST).
Previously, LIST operations were not applying the same normalization rules
(handling backslashes, duplicate slashes, leading slashes) as GET/PUT operations.

Changes:
- Updated normalizePrefixMarker() to call NormalizeObjectKey for both prefix and marker
- This ensures prefixes with leading slashes, backslashes, or duplicate slashes are
  handled consistently with how object keys are normalized
- Fixes Parquet test failures where pads.write_dataset creates implicit directory
  structures that couldn't be discovered by subsequent LIST operations
- Added TestPrefixNormalizationInList and TestListPrefixConsistency tests

All existing LIST tests continue to pass with the normalization improvements.

* Add debugging logging to LIST operations to track prefix normalization

* Fix: Remove leading slash addition from GetPrefix to work with NormalizeObjectKey

The NormalizeObjectKey function removes leading slashes to match S3 API format
(e.g., 'foo/bar' not '/foo/bar'). However, GetPrefix was adding a leading slash
back, which caused LIST operations to fail with incorrect path handling.

Now GetPrefix only normalizes duplicate slashes without adding a leading slash,
which allows NormalizeObjectKey changes to work correctly for S3 LIST operations.

All Parquet integration tests now pass (20/20).

* Fix: Handle object paths without leading slash in checkDirectoryObject

NormalizeObjectKey() removes the leading slash to match S3 API format.
However, checkDirectoryObject() was assuming the object path has a leading
slash when processing directory markers (paths ending with '/').

Now we ensure the object has a leading slash before processing it for
filer operations.

Fixes implicit directory marker test (explicit_dir/) while keeping
Parquet integration tests passing (20/20).

All tests pass:
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* Fix: Handle explicit directory markers with trailing slashes

Explicit directory markers created with put_object(Key='dir/', ...) are stored
in the filer with the trailing slash as part of the name. The checkDirectoryObject()
function now checks for both:
1. Explicit directories: lookup with trailing slash preserved (e.g., 'explicit_dir/')
2. Implicit directories: lookup without trailing slash (e.g., 'implicit_dir')

This ensures both types of directory markers are properly recognized.

All tests pass:
- Implicit directory tests: 6/6 (including explicit directory marker test)
- Parquet integration tests: 20/20

* Fix: Preserve trailing slash in NormalizeObjectKey

NormalizeObjectKey now preserves trailing slashes when normalizing object keys.
This is important for explicit directory markers like 'explicit_dir/' which rely
on the trailing slash to be recognized as directory objects.

The normalization process:
1. Notes if trailing slash was present
2. Removes duplicate slashes and converts backslashes
3. Removes leading slash for S3 API format
4. Restores trailing slash if it was in the original

This ensures explicit directory markers created with put_object(Key='dir/', ...)
are properly normalized and can be looked up by their exact name.

All tests pass:
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

* clean object

* Fix: Don't restore trailing slash if result is empty

When normalizing paths that are only slashes (e.g., '///', '/'), the function
should return an empty string, not a single slash. The fix ensures we only
restore the trailing slash if the result is non-empty.

This fixes the 'just_slashes' test case:
- Input: '///'
- Expected: ''
- Previous: '/'
- Fixed: ''

All tests now pass:
- Unit tests: TestNormalizeObjectKey (13/13)
- Implicit directory tests: 6/6
- Parquet integration tests: 20/20

Chris Lu 55f0fbf364 s3: optimize DELETE by skipping lock check for buckets without Object Lock (#7642)
This optimization avoids an expensive filer gRPC call for every DELETE
operation on buckets that don't have Object Lock enabled.

Before this change, enforceObjectLockProtections() would always call
getObjectEntry() to fetch object metadata to check for retention/legal
hold, even for buckets that never had Object Lock configured.

Changes:
1. Add early return in enforceObjectLockProtections() if bucket has no
   Object Lock config or bucket doesn't exist
2. Add isObjectLockEnabled() helper function to check if a bucket has
   Object Lock configured
3. Fix validateObjectLockHeaders() to check ObjectLockConfig instead of
   just versioningEnabled - this ensures object-lock headers are properly
   rejected on buckets without Object Lock enabled, which aligns with
   AWS S3 semantics
4. Make bucket creation with Object Lock atomic - set Object Lock config
   in the same CreateEntry call as bucket creation, preventing race
   conditions where bucket exists without Object Lock enabled
5. Properly handle Object Lock setup failures during bucket creation -
   if StoreObjectLockConfigurationInExtended fails, roll back the bucket
   creation and return an error instead of leaving a bucket without
   the requested Object Lock configuration

This significantly improves DELETE latency for non-Object-Lock buckets,
which is the common case (lockCheck time reduced from 1-10ms to ~1µs).

Chris Lu 39ba19eea6 filer: async empty folder cleanup via metadata events (#7614)
* filer: async empty folder cleanup via metadata events

Implements asynchronous empty folder cleanup when files are deleted in S3.

Key changes:

1. EmptyFolderCleaner - New component that handles folder cleanup:
   - Uses consistent hashing (LockRing) to determine folder ownership
   - Each filer owns specific folders, avoiding duplicate cleanup work
   - Debounces delete events (10s delay) to batch multiple deletes
   - Caches rough folder counts to skip unnecessary checks
   - Cancels pending cleanup when new files are created
   - Handles both file and subdirectory deletions

2. Integration with metadata events:
   - Listens to both local and remote filer metadata events
   - Processes create/delete/rename events to track folder state
   - Only processes folders under /buckets/<bucket>/...

3. Removed synchronous empty folder cleanup from S3 handlers:
   - DeleteObjectHandler no longer calls DoDeleteEmptyParentDirectories
   - DeleteMultipleObjectsHandler no longer tracks/cleans directories
   - Cleanup now happens asynchronously via metadata events

Benefits:
- Non-blocking: S3 delete requests return immediately
- Coordinated: Only one filer (the owner) cleans each folder
- Efficient: Batching and caching reduce unnecessary checks
- Event-driven: Folder deletion triggers parent folder check automatically

* filer: add CleanupQueue data structure for deduplicated folder cleanup

CleanupQueue uses a linked list for FIFO ordering and a hashmap for O(1)
deduplication. Processing is triggered when:
- Queue size reaches maxSize (default 1000), OR
- Oldest item exceeds maxAge (default 10 minutes)

Key features:
- O(1) Add, Remove, Pop, Contains operations
- Duplicate folders are ignored (keeps original position/time)
- Testable with injectable time function
- Thread-safe with mutex protection

* filer: use CleanupQueue for empty folder cleanup

Replace timer-per-folder approach with queue-based processing:
- Use CleanupQueue for deduplication and ordered processing
- Process queue when full (1000 items) or oldest item exceeds 10 minutes
- Background processor checks queue every 10 seconds
- Remove from queue on create events to cancel pending cleanup

Benefits:
- Bounded memory: queue has max size, not unlimited timers
- Efficient: O(1) add/remove/contains operations
- Batch processing: handle many folders efficiently
- Better for high-volume delete scenarios

* filer: CleanupQueue.Add moves duplicate to back with updated time

When adding a folder that already exists in the queue:
- Remove it from its current position
- Add it to the back of the queue
- Update the queue time to current time

This ensures that folders with recent delete activity are processed
later, giving more time for additional deletes to occur.

* filer: CleanupQueue uses event time and inserts in sorted order

Changes:
- Add() now takes eventTime parameter instead of using current time
- Insert items in time-sorted order (oldest at front) to handle out-of-order events
- When updating duplicate with newer time, reposition to maintain sort order
- Ignore updates with older time (keep existing later time)

This ensures proper ordering when processing events from distributed filers
where event arrival order may not match event occurrence order.

* filer: remove unused CleanupQueue functions (SetNowFunc, GetAll)

Removed test-only functions:
- SetNowFunc: tests now use real time with past event times
- GetAll: tests now use Pop() to verify order

Kept functions used in production:
- Peek: used in filer_notify_read.go
- OldestAge: used in empty_folder_cleaner.go logging

* filer: initialize cache entry on first delete/create event

Previously, roughCount was only updated if the cache entry already
existed, but entries were only created during executeCleanup. This
meant delete/create events before the first cleanup didn't track
the count.

Now create the cache entry on first event, so roughCount properly
tracks all changes from the start.

* filer: skip adding to cleanup queue if roughCount > 0

If the cached roughCount indicates there are still items in the
folder, don't bother adding it to the cleanup queue. This avoids
unnecessary queue entries and reduces wasted cleanup checks.

* filer: don't create cache entry on create event

Only update roughCount if the folder is already being tracked.
New folders don't need tracking until we see a delete event.

* filer: move empty folder cleanup to its own package

- Created weed/filer/empty_folder_cleanup package
- Defined FilerOperations interface to break circular dependency
- Added CountDirectoryEntries method to Filer
- Exported IsUnderPath and IsUnderBucketPath helper functions

* filer: make isUnderPath and isUnderBucketPath private

These helpers are only used within the empty_folder_cleanup package.

* test versioning also

* fix some versioning tests

* fall back

* fixes

Never-versioned buckets: No VersionId headers, no Status field
Pre-versioning objects: Regular files, VersionId="null", included in all operations
Post-versioning objects: Stored in .versions directories with real version IDs
Suspended versioning: Proper status handling and null version IDs

* fixes

Bucket Versioning Status Compliance
Fixed: New buckets now return no Status field (AWS S3 compliant)
Before: Always returned "Suspended" 
After: Returns empty VersioningConfiguration for unconfigured buckets 
2. Multi-Object Delete Versioning Support
Fixed: DeleteMultipleObjectsHandler now fully versioning-aware
Before: Always deleted physical files, breaking versioning 
After: Creates delete markers or deletes specific versions properly 
Added: DeleteMarker field in response structure for AWS compatibility
3. Copy Operations Versioning Support
Fixed: CopyObjectHandler and CopyObjectPartHandler now versioning-aware
Before: Only copied regular files, couldn't handle versioned sources 
After: Parses version IDs from copy source, creates versions in destination 
Added: pathToBucketObjectAndVersion() function for version ID parsing
4. Pre-versioning Object Handling
Fixed: getLatestObjectVersion() now has proper fallback logic
Before: Failed when .versions directory didn't exist 
After: Falls back to regular objects for pre-versioning scenarios 
5. Enhanced Object Version Listings
Fixed: listObjectVersions() includes both versioned AND pre-versioning objects
Before: Only showed .versions directories, ignored pre-versioning objects 
After: Shows complete version history with VersionId="null" for pre-versioning 
6. Null Version ID Handling
Fixed: getSpecificObjectVersion() properly handles versionId="null"
Before: Couldn't retrieve pre-versioning objects by version ID 
After: Returns regular object files for "null" version requests 
7. Version ID Response Headers
Fixed: PUT operations only return x-amz-version-id when appropriate
Before: Returned version IDs for non-versioned buckets 
After: Only returns version IDs for explicitly configured versioning

TestVersioningDeleteAndRecreate - PASS
TestVersioningListWithPagination - PASS
 Some advanced features still failing:
ETag calculation issues (using mtime instead of proper MD5)
Specific version retrieval (EOF error)
Version deletion (internal errors)
Concurrent operations (race conditions)

* calculate multi chunk md5

 TestVersioningMultipleVersionsSameObject - PASS
 TestVersioningDeleteMarkers - PASS

* dedupe

* fix TestVersioningErrorCases

* fix eof error of reading old versions

* get specific version also check current version

* enable integration tests for versioning

* trigger action to work for now

* Fix GitHub Actions S3 versioning tests workflow

- Fix syntax error (incorrect indentation)
- Update directory paths from weed/s3api/versioning_tests/ to test/s3/versioning/
- Add push trigger for add-object-versioning branch to enable CI during development
- Update artifact paths to match correct directory structure

* Improve CI robustness for S3 versioning tests

Makefile improvements:
- Increase server startup timeout from 30s to 90s for CI environments
- Add progressive timeout reporting (logs at 30s, full logs at 90s)
- Better error handling with server logs on failure
- Add server PID tracking for debugging
- Improved test failure reporting

GitHub Actions workflow improvements:
- Increase job timeouts to account for CI environment delays
- Add system information logging (memory, disk space)
- Add detailed failure reporting with server logs
- Add process and network diagnostics on failure
- Better error messaging and log collection

These changes should resolve the 'Server failed to start within 30 seconds' issue
that was causing the CI tests to fail.

Warren HodgkinsonandChris Lu a1a76ccb8c Fix for DeleteMultipleObjectsHandler wrongly deleting parent folders (#6380)
What problem are we solving?
Fix: #6379

How are we solving the problem?
We check for the AllowEmptyFolders option prior to cascade
deleting parent folders in S3 DeleteMultipleObjectsHandler.

How is the PR tested?
We ran SeaweedFS in a Kubernetes Cluster with a joint Filer
and S3 server in one container, with leveldb2 as the filer storage,
and AllowEmptyFolders set to true.

When using the Distribution Registry as the S3 client, it calls the
DeleteMultipleObjectsHandler as part of the artifact upload process
(uploads to a temp location, then performs a copy and delete).
Without this fix, the deletion cascade deleted parent folder until
the entire contents of the bucket were gone.

With this fix, the existing content of the bucket remained, and the
newly uploaded content was added.

Checks
[ ] I have added unit tests if possible.
[ ] I will add related wiki document changes and link to this PR after merging.
