0dd33bd7ec s3api: fix ListObjectsV2 dropping objects under a partial prefix (#10656)
* s3api: fix ListObjectsV2 dropping objects under a partial prefix

ListObjectsV2 with a prefix that names only part of a directory name -
"data/a" matching both "data/a/..." and "data/ab/..." - dropped objects
when paginating with a small max-keys, reporting IsTruncated=false before
all matching keys had been returned.

On resume, normalizePrefixMarker took the listing directory from the
continuation marker ("data/a/") and discarded the "a" name prefix, so once
the marker's subtree was exhausted the sibling directories that also
matched the prefix were never listed.

Resolve the listing directory and name prefix from the prefix instead of
the marker, so siblings sharing the name prefix are still listed after the
marker's subtree.

Fixes #10652

* s3api: cover a sibling-directory marker in the partial prefix tests

* s3api: resume a truncated delimited listing from the emitted CommonPrefix

Rebuilding the continuation token from the request dir plus the listing prefix
assumes that prefix names a directory. With a partial name prefix like "data/a"
it produced "data/a/ab/" for the sibling prefix "data/ab/", so the next page
resumed in the wrong subtree and repeated it forever.

Chris LuandGitHub a2ffc7aadf heartbeat: keep the master current through collection churn (#10657)
* heartbeat: name departed volumes in delta heartbeats

* master: release the lookup index with a deleted collection

* master: keep a fresh grow safe from the report that raced it

* volume: name the volumes a deleted collection took with it

Deleting a collection left the master to work out what went by omission from
the next full volume list, which it no longer gets: heartbeats carry the whole
list only when the master asks for it. The volumes a bucket's churn creates and
destroys between two of those requests are never named in either direction, so
the master keeps counting their slots as occupied and a cluster that creates
and drops collections quickly runs its free-slot accounting dry -- assigns fail
with no free volumes left while the disk holds a handful of volumes.

The destroy path already knows exactly which volumes it removed, so send them
down the same channel every other deletion uses.

* rust: name the volumes a deleted collection took with it

Mirrors the Go volume server. The notify path derives its deltas by diffing
snapshots, so a collection delete that does not wake it is invisible until the
master next asks for the whole list.

Chris LuandGitHub 25d7f62749 topology: mark a volume crowded only if it can take writes (#10655)
* topology: mark a volume crowded only if it can take writes

Crowding asks for more room to write into, and the writable-volume refresh loop
marked anything past the threshold regardless of whether writes could land
there. Growth already discounts those by intersecting the crowded set with the
writable list, so the entries changed no decision and only took space -- in a
tiered cluster, one for nearly every volume.

* topology: wait for the crowded-volume collector before reading what it saw

Closing the stop channel does not order the collector's writes against the
test's reads.

* topology: drop the sleep from the crowded-volume test

The channels are unbuffered, so every send has been received by the time the
sweep returns, and waiting for the collector covers the recording. The sleep
only suggested the result turned on timing.

Chris LuandGitHub 3a61debaa5 filer: rebuild peer metadata subscriptions after a master reconnect (#10648)
* filer: keep the existing peer subscription on a repeated add

A cluster node add for a peer that is already followed restarted the
subscription, dropping the metadata events between the two runs.

* master: tell a connecting client the current cluster membership

Cluster node updates are only broadcast to the clients connected at that
moment. A filer that lost its master stream while a peer came back never
learned about the peer, and stopped replicating its metadata for good.

* test: a filer joining the master learns about the filers already there

* test: a filer resubscribes to a peer that registered while it was disconnected

Runs the reported sequence against real processes: filer2 leaves, filer1
is paused and its master stream is broken, filer2 registers again, and
filer1 has to replicate from it after reconnecting.

Chris LuandGitHub 37f3dff677 volume: validate the file extension in CopyFile and ReceiveFile (#10644)
* volume: validate the file extension in CopyFile and ReceiveFile

CopyFile and ReceiveFile build an on-disk path from the client-supplied
Ext. Both are intentionally ungated for cluster-internal peers, so a
value like "/../../x" is joined onto the volume directory and, once
path-cleaned, resolves outside it -- an EC-shard receive can then write,
and CopyFile read, anywhere the process can reach.

Constrain Ext to a real suffix (a leading dot followed by alphanumerics)
before it is used to build any path, so it can no longer carry a
separator or a parent reference.

* test: use an alphanumeric missing-file extension in the copy variants

The not-found and stop-offset-zero cases used ".definitely-missing" as a
deliberately absent source. The extension is now validated, and the hyphen
makes it invalid, so switch to ".missing" -- still a nonexistent file, but a
real extension shape.

* volume: validate the collection in CopyFile and ReceiveFile

The client-supplied Collection is folded into the on-disk path as
"<collection>_<vid>" by VolumeFileName and EcShardBaseFileName, both joined
with path.Join / util.Join. A Collection carrying a separator, e.g.
"../../x", therefore path-cleans to a target outside the volume directory,
the same escape the extension check just closed. Reject a collection that is
a bare parent reference or holds a separator; ordinary names ('.', '-' and
all) still pass.

Chris LuandGitHub 9d11278d95 filer: add filer.meta.scan to audit one directory's change history (#10645)
* filer: drain pending log chunk refs when the metadata stream ends

In metadata chunks mode the server sends log file refs in responses of their
own, and the client can only read them once it knows the run of refs is over.
That was inferred solely from the arrival of a normal event, so refs still
pending when the stream ended were dropped: the subscription returned no
events and no error.

A follower never noticed, because it runs forever and a live event always
arrives to close the run. A bounded subscription — StopTsNs set, range already
in the past — can receive nothing but refs and then EOF, and silently reports
that nothing happened. For anything auditing a path that is the worst possible
answer, since an empty result is indistinguishable from a quiet period.

Drain on EOF as well as at the transition point.

* filer: add filer.meta.scan to audit one directory's change history

Reconstructing what happened to a path means replaying the metadata log, and
filer.meta.tail is built for watching rather than auditing: it follows forever
unless given a stop, prints multi-line JSON, and takes ranges only as durations
before now, so an incident timestamp has to be converted by hand.

Its -pattern also cannot find a versioned object. A versioned key is stored as
<key>.versions/v_<id>, so the events carry the names "<key>.versions" and
"v_<id>" and a pattern of the object's own name matches neither — the search
comes back empty while the object is being written continuously.

filer.meta.scan prints one line per change, stops at the end of the range,
accepts absolute -since/-until with an explicit -tz, and reports versioned
writes against the object key with the version id alongside, so -name matches
the key a client would ask for. Delete markers are labelled as such rather than
appearing as zero-length writes, and pointer flips on the .versions container
are distinguished from writes of object data.

* filer.meta.scan: read persisted log chunks from the volume servers

Reading a range through the filer makes it decode every log entry in that
range and filter each one, so the cost lands on the filer and does not shrink
when the prefix is narrow — only the bytes on the wire do. On a cluster whose
metadata log is dense that is the expensive part of a scan, and it is charged
to the process least able to spare it.

Enable metadata chunks mode: the filer hands out log chunk ids and the scan
reads them from the volume servers itself. ReadLogFileRefs re-applies the same
path filter client-side, so the output is unchanged — verified identical to
the filer-read path over the same range, including after a restart drops the
in-memory buffer and the data must come off disk.

Direct read needs a route to the volume servers that the filer does not, so a
failure before anything has been printed retries through the filer; retrying
after partial output would duplicate lines. -directRead=false forces it.

* filer.meta.scan: confirm an empty direct-read result through the filer

An audit that returns nothing is read as "nothing happened here", so it is the
one answer that must not be produced by a bug. Direct read has more ways to
come back empty than the filer path does — it needs a route to the volume
servers, and it depends on the ref-drain contract holding.

When direct read yields no changes, re-run through the filer before reporting
it, and warn if the two disagree. Re-running is safe only because nothing was
printed; after partial output a replay would duplicate lines instead, so that
case reports the error rather than retrying.

Chris LuandGitHub e9cde3e4b1 master: gate raft membership RPCs behind the admin whitelist (#10649)
* master: evict a dead peer via the local raft handle

OnPeerUpdate only runs on the leader, and the AddVoter branch right above
mutates the local raft directly. The remove branch instead dialed our own
RaftRemoveServer back over gRPC. Drop the self-dial and remove the peer
through the local handle, matching the add path. This also leaves operator
tooling as the only caller of the RaftRemoveServer RPC.

* master: require whitelist auth for raft membership RPCs

RaftAddServer, RaftRemoveServer and RaftLeadershipTransfer rewrite raft
quorum but had no caller check beyond "am I the leader". Any client that
could reach the master gRPC port could add an unreachable phantom voter
and stall the write path.

Gate the three on the admin whitelist, mirroring the volume server's
checkGrpcAdminAuth. With no whitelist configured the guard allows every
caller, so default and single-master deployments are unaffected;
operators who set -whiteList get these RPCs locked down to it. The
leader's own dead-peer eviction no longer dials these RPCs, so the only
remaining callers are operator tooling.

Chris LuandGitHub ce7d388639 heartbeat: send only the volumes that changed (#10640)
* pb: let a heartbeat carry only the volumes that changed

A partial list cannot travel in volumes: a master that did not understand it
would read the absences as deletions. So changes get their own field, used only
once the master has said it compares digests and can tell when it has fallen
behind.

* master: apply the volumes a heartbeat reports as changed

Only the named volumes are touched. A full report says the server holds exactly
these; a changed report says nothing about the ones it leaves out, so absence
must not read as removal.

Also advertises that the master compares digests, which is what lets a server
stop sending its whole list. Advertising it once per connection means a server
reconnecting to a master that does not is back to full lists straight away.

* volume: send only the volumes that changed once the master accepts them

The whole list goes on every heartbeat until the master says it compares
digests, and again whenever it asks, so a master that cannot tell when it has
fallen behind never has to.

has_no_volumes stays derived from a full list alone. Deriving it from what a
heartbeat happens to carry would make a quiet one read as a server that had
lost every volume, and the master would drop them all.

The digest still covers every volume held rather than the ones sent, which is
what lets the master confirm that applying the changes left it current.

Reporting state is per-connection: a server that reconnects, or reaches a
different master, starts again from the full list.

* volume: let the zero reporting state stand for having told no master anything

A Store built as a literal, which tests do, left the reporting state nil and
panicked on the first heartbeat. As a value its zero form already means nothing
has been reported to anyone, which is exactly the state that sends the whole
list.

* rust: send only the volumes that changed once the master accepts them

Mirrors the Go volume server, with one hazard the Go side does not have: mount
and unmount deltas here are derived by diffing successive heartbeats, so a
heartbeat that carries a partial list would report every volume it left out as
unmounted. Collecting now returns the full set alongside the message, and every
site that diffs uses that rather than what went on the wire.

* volume: do not let a full-list request be lost to the heartbeat it raced

The request arrived while a heartbeat was already being built as a delta, and
committing that heartbeat cleared it, so the master waited for another digest
mismatch before asking again. Count the requests and clear only the one the
heartbeat answered.

* rust: stop marking volumes reported by a heartbeat that is thrown away

The state-notify path collected a heartbeat only to diff its volume list, then
sent a delta message of its own and dropped the one it had collected. Once
collecting recorded what the master had been told, every mount or unmount
silently marked the changed volumes as sent, and the master learned of them
only after a digest mismatch.

Snapshotting no longer records anything, and no longer expires ec volumes
whose deletion that path was already discarding.

* master: announce only the volumes a change actually brought

Every changed volume was broadcast as a new location. Volumes grow constantly
and growth moves no location, so on a busy cluster that told every connected
client about volumes it could already reach, filling bounded broadcast queues
and pushing out the topology updates that matter.

* master: ask for the full list when only one can repair the master

Delta heartbeats stop the full report, and with it the only thing that
re-registers a volume the lookup index lost. The volume server cannot see that
divergence and its digest cannot show it, so the master now checks its own two
indexes agree and asks for the list when they do not.

A node reporting one volume id twice is kept on full lists for the same reason
rather than merely skipped: its digest can never be verified, so nothing else
would tell the master what it had stopped holding.

* master: keep the volume options on every heartbeat response

A volume server takes them from whatever response arrives, and preallocate is a
bare bool with no way to tell off from unmentioned. A response sent to ask for
the volume list therefore turned preallocation off until the server reconnected.

Responses sent mid-stream now start from the configured options rather than
being built field by field.

* master: announce a volume the lookup index had lost

Repairing the index makes the volume servable again, but clients were told it
went when the node dropped out and nothing told them otherwise: the disk map
still held it, so it did not count as an arrival.

Reaching the lookup index is what makes a volume servable, so recovering an
entry there is an arrival as far as clients are concerned, on both the full
report and the changed-volume path.

Chris LuandGitHub 08f0ba5564 topology: clamp the deleted-vs-total subtractions in volume stats (#10633)
VolumeLocationList.Stats subtracts the deleted figures from the totals to
report live size and needle count. Both deleted figures are maintained as
counters independent of the totals they come off, so either can transiently
exceed its total, and neither subtraction was clamped.

Unclamped, the size wraps to ~16 EB. The count is signed so it merely goes
negative, but VolumeLayout.Stats converts it with uint64(fileCount), which
turns it into ~1.8e19 just the same. Either one swamps the cluster totals
behind /dir/status, /vol/status and Topology.CollectionVolumeStats.

commandFsMergeVolumes.getVolumeSize had the same unclamped subtraction, where
a wrapped size reads as a volume far too large to join any merge plan.

Clamped to zero, matching the guards already in CollectionInfo.LogicalSize
and the admin server's logical-size accumulator.

Chris LuandGitHub 4527947afc mount: absorb the WinFsp metadata cache window in the concurrent-reader test (#10636)
WriteFile's own existence probe runs while the file does not exist, and
WinFsp may serve that answer from its metadata cache for up to the
mount's FileInfoTimeout. A reader racing into that window failed its
open with not-found, which is the cache being a cache, not a defect in
concurrent reading. Establish visibility once before racing the readers,
so the test exercises what it is named for.

Chris LuandGitHub 0b78381513 wdclient: keep the location of a volume reported added and removed at once (#10635)
* wdclient: keep the location of a volume reported added and removed at once

A volume moved between a server's disks arrives in both lists of one message,
and the server still has it. Additions were applied before removals, so the
removal won and the client was left with no location for a volume that never
went anywhere.

Reordering would swap the bug for a window where the volume resolves nowhere,
since the two updates take the lock separately. Skip the removal instead, so
the order the lists are applied in stops mattering.

* wdclient: build each ec update explicitly in the move test

Reusing one response object and adding the deletion to it left the overlap the
test turns on implicit, and reading it as a delete-only update is the natural
mistake.

Chris LuandGitHub 5ec813b4f1 topology: follow a volume that moved between a server's disks (#10628)
* topology: follow a volume that moved between a server's disks

The heartbeat diff asked only whether a volume id was reported anywhere on the
node, so a volume that moved to a disk of another type stayed on the disk it
left as well. The master then held two copies of it forever: the volume count
was overstated, and GetVolumesById returned whichever disk the map iterated
first, so lookups could hand back the disk the volume had already left.

Track which disk types the heartbeat named each volume on, and treat a volume
named on another disk as absent from this one. Disk types are interned to an
index because a server reports a handful of them across hundreds of thousands
of volumes.

A volume named on two disks at once is a stale twin rather than a move, and is
still kept on both -- dropping one would tell the master a replica vanished.
Only a volume named twice on one disk type is unrepresentable, so that is now
what marks the node, rather than any repeat of an id.

* master: do not tell clients a moved volume left the node

A volume moved between a node's disks is removed from one and added to the
other, so it lands in both lists of the same heartbeat. Clients apply additions
before deletions, so the removal wins and they end up with no location for a
volume that never went anywhere.

Skip removals for volumes the node still holds, as the ec shard paths already
do, and update the topology before judging the delta removals so an unmount
that really did happen is still reported.

* trim the comments on this change to the parts that are not evident

* master: judge a volume removal on normal replicas alone

HasVolumesById answers for ec shards as well, so a replica encoded into ec
shards looked like it was still on the node and clients were never told the
normal location had gone. They hold normal and ec locations separately and
prefer the normal one from the same generation, so that location would have
gone on shadowing the shards.

Chris LuandGitHub 75ae33ade8 mount: let the kernel cache directory listings (#10634)
Every enumeration of a directory walked the whole FUSE machinery, so
reopening a folder cost what opening it did. The kernel has a cache for
exactly this: with FOPEN_CACHE_DIR the listing lives in the directory's
page cache and a repeat enumeration never reaches the mount at all.

Local mutations already drop that cache in the kernel. Remote ones
arrive through the metadata subscription, so the entry invalidation
worker now also tells the kernel which directory changed. The worker is
the one place this is safe from: notifying from a thread serving a
kernel request can deadlock against the page it holds, which is why the
file paths deliberately avoid InodeNotify.

Measured in a Linux container, 20k-entry directory, ls repeated:

    warm listing   before 199-355ms   after 6-9ms

A file written from outside the mount appeared in the next listing
within a second, through the subscription notify, and the listing
re-cached after.

The memory is the kernel's page cache: reclaimed under pressure, owned
per-directory, and covering read-through directories the mount-side
caches never see.

Chris LuandGitHub dd73fee077 mount: read oversized directories through instead of caching them (#10631)
* mount: read oversized directories through instead of caching them

Visiting a directory pulls every child from the filer into the local
LevelDB before the first listing returns. For a directory of a few
million entries that is minutes of streaming, gigabytes of local store,
and gigabytes of decoded entries in flight -- paid by a mount that may
only walk the directory once.

A build that crosses -cacheDirMaxEntries (default ten thousand) now
stops, cleans up, and marks the directory read-through: listings stream
from the filer with pagination, the way update-hot directories already
do, and lookups in it consult the filer per entry as any uncached
directory does. The refusal is remembered, so the next visit fails fast
instead of streaming to the limit again, and an oversized ancestor is
stepped over when caching its subdirectories rather than wedging every
listing beneath it.

The direct path keeps the same pagination state on the handle, so a walk
that crosses the limit mid-flight carries on from where the cached walk
reached.

* mount: an ancestor found oversized must not fail its descendants

Visiting a directory builds its whole uncached ancestor chain in one
group, so the first discovery that an ancestor is oversized cancelled the
group and surfaced as the listed directory's own refusal: the descendant
build was aborted and the caller marked the descendant read-through,
leaving a perfectly cacheable directory streaming from the filer until
its inode was forgotten. The earlier test missed this by pre-marking the
ancestor, which exercises only the fast path.

The refusal of any directory other than the one being listed is now kept
out of the group's result; it is already remembered for the next visit.

Chris LuandGitHub 506ce0850b telemetry: count erasure-coded volumes in the reported totals (#10632)
collectVolumeStats walked only DataNode.GetVolumes(), which returns the
regular volumes on each disk. An encoded volume leaves that set and is
reported through GetEcShards instead, so total_disk_bytes and
total_volume_count silently excluded every erasure-coded volume: a cluster
that encoded everything reported zero bytes and zero volumes while still
counting as a volume server.

Sum each holder's shard sizes into the byte total, parity and extra copies
included, matching how a replicated volume's used size counts every replica
and how CollectionEcVolumeStats already reports EC footprint. Count volume
ids rather than shard entries, since one volume's shards are spread over
many nodes and would otherwise multiply the volume count by the number of
holders.

Chris LuandGitHub 6d08b08f37 heartbeat: carry a volume digest and verify it (#10627)
* pb: carry a volume digest on the heartbeat

The full volume list is the only way a master notices a volume that vanished
without a delta, so it cannot simply be dropped. A digest gives the same
guarantee without the list, and a way back to the list when they disagree.

The digest has explicit presence: a server holding no volumes reports 0, which
has to stay distinguishable from a server that does not compute one at all.

* volume: report a digest of the volumes each heartbeat carries

Digests exactly what goes on the wire: volumes skipped as quarantined, phantom
or expired are absent from both the list and the digest, so the master compares
against the same set the server meant to report.

Runs the master's own hash over the master's own conversion of the message, so
the two ends cannot drift into disagreeing about a field.

* master: check the reported volume digest and ask for the list on a mismatch

Compared after everything the heartbeat carried has been applied, so agreement
means the master is current rather than that nothing changed.

Servers reporting no digest are untouched, and a mismatch on a heartbeat that
already carried the full list is reported rather than answered: there is
nothing further to ask for, so asking again would loop. Nodes reporting one
volume id twice are skipped for the same reason.

* rust: report the heartbeat volume digest

Mirrors the Go volume server. The master compares this against a digest it
computes itself, so the hash has to agree byte for byte across the two
implementations, not merely be a hash of the same fields: report_hash_vectors
pins it against values generated by the Go side, and the ttl and replica
placement narrowing the master applies when it decodes a message is applied
here too rather than assumed away.

A drift there would not corrupt anything, but every volume server on this
implementation would report a digest the master can never match and fall back
to sending its whole volume list forever, which is the cost the digest exists
to avoid.

* master: pin what the digest check does to each kind of report

The upgrade story rests on these: a server that reports no digest is never
asked for anything, so the two sides can be upgraded in either order, and a
disagreement that resending cannot fix is reported rather than re-asked, so it
cannot loop.

* topology: enumerate the digest coverage test from the message

The list of fields was written out by hand, so a field added to
VolumeInformationMessage later would fall outside the digest while the test
went on passing, and a change to it would never reach the master. Walk the
message descriptor instead.

Some fields are narrowed or normalised on the way into VolumeInfo, so the
smallest change to the wire value can land back on the stored one; the test
offers several values per field and asks only that some change is visible.

The two answer different questions and the pie was the better answer to one
of them: what the fleet is on right now, at a glance. Restore it under its

is the last day of the chart below it.

* telemetry: draw the distribution pies at the size of their cards

Both pies kept the canvas tag's 2:1 ratio at the card's full width, so they
came out around 560px tall and spilled past the card they sit in. Give them a
height to fill instead, and build every chart after the dashboard is shown: a
canvas in a display:none container measures zero, and a pie sized from that
never grows back.

Chris LuandGitHub 553bc5ab90 topology: digest the volumes a master believes each node holds (#10619)
* topology: digest the volumes a master believes each node holds

A volume server resends its whole volume list every heartbeat because that list
is the only way the master can notice a volume that vanished without a delta.
A digest gives the master the same guarantee without the list: the two ends
agree iff the master's copy is current.

VolumeInfo.ReportHash covers every field of VolumeInformationMessage, so a
change the hash misses is a change the master would never hear about. Both ends
run it over the same converted VolumeInfo, so they cannot drift apart.

Disk keeps the xor of its volumes' hashes, which is order-independent and its
own inverse, so add, update and remove each stay O(1) and the running value
needs no per-volume storage.

Nothing reads the digest yet; the heartbeat protocol change comes next.

* topology: test that a changed-volumes-only heartbeat reconciles

The digest is not a change detector -- in a live cluster some volumes always
have changed. It answers whether the master holds what the volume server holds
once the heartbeat's own changes are applied, so reporting three volumes out of
fifty has to reconcile while a volume lost without a delta must not.

* topology: digest the lookup index too, not just the disk maps

The reported digest answers whether the master holds what the volume server
holds. It cannot answer whether the master can serve those volumes: the disk
map and the lookup index are maintained separately, and a disconnect racing a
reconnect drops a volume from the index while leaving it on the node. The
server's report is identical either way, so a digest built from the disk maps
alone matches while the volume answers 'volume id not found'.

Track a second digest over volume ids on both sides of that split, so the
master can see its own indexes disagree without the volume server's help, and
without the O(volumes) scan the full heartbeat currently relies on.

* topology: exclude nodes reporting a duplicate volume id from the digest

A volume id can end up mounted on two disks of one server -- a stale twin
re-attached after a disk repair, which the store handles rather than rejects.
The server reports both copies with different disk ids, but the master keys
volumes by id alone within a disk type and keeps only the last one. Its digest
can then never equal the server's, and no amount of resending the full list
would fix it.

Detect it from the report itself, where deduplicating the ids already tells us
the count, and mark the node. A marked node has to keep sending full lists;
representing both copies is a separate question, and nesting the volume map by
disk id would cost more memory than the digest saves.

* topology: move the lookup digest with the entry, not the node passed in

Two volume servers can hold one address: GetOrCreateDataNode keys on the id a
server reports and refuses to merge a new id onto an address an older node
still claims, while the lookup list keys on address alone. Registering the
second server therefore displaces the first from the entry, and unregistering
through either removes whichever node the entry named.

Crediting the node handed to Set and Remove instead of the one actually
displaced or removed left the digest on the wrong node. A displaced node went
on reporting a consistent index while it could no longer serve the volume,
which is exactly the silent unavailability the digest exists to catch.

Set and Remove now return the node they displaced and removed, so ownership
can be transferred rather than assumed.

Chris LuandGitHub 12627d376d mount: fix four readdir pagination bugs (#10624)
* mount: size the direct listing slice from the batch, not the offset

The limit passed here is skipCount+batchSize when a client resumes a
fresh handle partway through a directory, so preallocating for it turns
the client's cookie into an allocation: a readdir at offset 3,000,000
reserves 24MB before the first entry arrives, and an offset near the
uint32 ceiling asks makeslice for ~4.29e9 elements.

* mount: stop replaying a directory that shrank past the resume offset

A client that opens a fresh handle and resumes at a cookie from an
earlier, larger listing gets a preload that cannot reach the entry before
that offset. The resume name was then left empty and the follow-up batch
listed from the directory's first child again, so the client was handed
every name a second time.

The stream always runs from the first child, so failing to reach that
entry means the directory is simply shorter than the offset. That is the
end of it.

* mount: page a directory from where the store reached

The batch loader treated a short batch as the end of the directory, but
the meta cache drops an expired child after the store has already spent
it against the limit, so a batch that filled up could still deliver fewer
entries than asked for. A directory with a handful of expired children
would stop listing early and hide every child behind them; a whole batch
of expired ones truncated the listing to nothing.

ListDirectoryEntries now reports the name the store itself reached. That
is both the sound end-of-directory signal -- the store returning nothing
-- and the right cursor, since resuming from the last visible name would
re-read the dropped children every round and never get past a batch that
was entirely expired.

* mount: drop the entries a directory walk has already passed

entryStreamOffset was only ever written by reset, so the stream a handle
holds grew for the life of the walk and a directory was retained whole
even though nothing could read the entries behind the client's position
again. A 10M-entry walk parked millions of entries per handle, and
NFS-Ganesha opens several on the same directory.

Offsets index into the stream from entryStreamOffset, so advancing the
two together keeps them lined up. One entry is held back because the next
batch resumes from the name immediately before the offset. Seeking back
behind what is still held now restarts the directory, which is what the
offset scheme can honestly support -- it previously returned nothing.

Chris LuandGitHub a49cf11e16 telemetry: version distribution over time (#10625)
* telemetry: keep the reported version in the daily history

The version only ever lived on the instance record, which holds a cluster's
latest report, so there was no way to ask what anything ran last Tuesday.
Record it per sample, and let the daily axis carry strings as well as counts.

State written before this has no version on its samples. The newest sample is
the report the instance record itself came from, so fill that one in on load
rather than starting a version series a day late.

* telemetry: serve the fleet's version make-up over time

/api/versions gives how many clusters ran each release per day, on the same
axis and hold-forward rule as the cluster sizes. Releases are ordered by
number rather than by size: the caller stacks them, and a stack whose order
changes with the counts is unreadable over time. The tail past the limit is
summed into "other" so the stack still adds up.

Days with no version are dropped before the axis is built, so the series
spans the days it knows a version for instead of climbing out of blanks.

* telemetry: draw version distribution as a stacked growth chart

The pie only ever showed today. Stacked over 30 days the height is the
confirmed fleet and each band is a release, so one chart carries the growth
and the rollouts at once. Newest release on the floor, so the band being read
is anchored to the axis instead of riding on everything below it.

Eight fixed hues instead of the evenly spaced ones the cluster stacks use:
evenly spaced put a green and a cyan close enough to be hard to tell apart,
which matters for a set you read rather than a wall of anonymous ids.
Versions past the eighth fold into "other", and each band carries its own
number so the chart reads without matching colours against the legend.

Chris LuandGitHub b46946ece5 filer: list directories without decoding chunk lists (#10616)
* filer: decode a listed entry without building its chunk list

A readdir reads attributes and never looks at chunks, but decoding an
entry builds the whole chunk list first: four allocations per chunk, all
of it thrown away. On a directory of ordinary 4MB-chunked files that is
most of what listing costs.

DecodeAttributesOnly walks the wire format and hands everything except
the chunks to the generated unmarshaller, so new fields in filer.proto
need no attention here. The chunks are still measured, because the S3
copy and multipart paths deliberately store a zero FileSize and let the
chunk extents define the size, but nothing is allocated to do it.

The blob is only re-encoded once a chunk is actually seen, so an entry
without any -- every directory, for one -- is unmarshalled where it lies
and pays nothing for the walk.

Listings opt in through the context, the way the lazy remote paths
already do; a store that ignores it stays correct.

    chunks   full      attrs-only              allocs
    0        312.8n    310.1n    ~              1 ->  1
    1        686.1n    411.1n    -40.07%        7 ->  1
    4        1.742u    667.4n    -61.69%       24 ->  1
    16       5.770u    1.544u    -73.25%       86 ->  1
    64       25.23u    6.004u    -76.20%      328 ->  1

* mount: list directories with chunk lists omitted

The two meta cache listings behind a readdir are the only callers, and
neither reads a chunk. On 200k single-chunk files one enumeration goes
from 364ms to 277ms and drops a million allocations.

The read-through listing still fetches whole entries from the filer,
which would need the request to say it wants attributes only.

* mount: give the readdir benchmark's entries a chunk

Chunkless entries made the decode look far cheaper than it is, which is
the part of a listing worth measuring.

* filer: let a listing ask for entries without their chunk lists

The read-through readdir fetches whole entries over gRPC, and for a wide
directory the chunk lists are most of what crosses the wire and most of
what the client then unmarshals. A 4MB-chunked file is 113 bytes of
entry against 46 without its chunk.

ListEntriesRequest gains omit_chunks. The size a client needs is already
in the attributes, where the store decode folded the chunk extents in,
so dropping the list costs the client nothing.

The filer still reads the entries whole. A listing is where a TTL-expired
entry gets collected and deleted, and deleting one needs its chunks to
find the data, so omitting them there would leak. Only the response is
trimmed.

The hint moves to filer_pb so one context flag serves both transports:
the gRPC request sets omit_chunks, and a listing served from the local
store skips building the chunks. Cache population is unaffected either
way, since EnsureVisited starts from its own context.

* filer: reject a chunk the full decoder would reject

The walk skipped a chunk's bytes without looking inside them, so a
FileChunk carrying a corrupt nested fid, or a string that is not valid
UTF-8, sailed past the listing decoder while every other read of the same
entry still failed. The file listed with a plausible size and then gave
EIO on open, and corruption that used to fail the listing loudly was
hidden instead.

The chunk bytes are the one part of the blob the generated unmarshaller
never sees, so the two checks it would have made are made here: a
submessage has to parse, and a proto3 string has to be valid UTF-8.
FileChunk's only submessages are FileIds of scalars, so walking them is a
complete check. A descriptor-driven test fails if FileChunk ever gains a
field of either kind that the walk does not know to check, which is the
part that keeps this honest as filer.proto grows.

Taking the scratch buffer lazily, only once a chunk is actually dropped,
also takes the pool out of the path for entries that have none. Those
were measurably slower than the full decoder before; they are now level
with it. Each chunk's length prefix is parsed once rather than twice.

    chunks   full       attrs-only   vs base
    0        171.4n     176.9n       ~ (p=0.670)
    1        366.6n     259.4n       -29.24%
    4        1.034u     500.2n       -51.60%
    16       3.905u     1.464u       -62.52%
    64       13.48u     5.195u       -61.46%

* filer: carry the size before dropping chunks over the wire

Dropping the chunk list assumed every store folds the chunk extents into
FileSize when it decodes. A store that keeps entries as JSON rather than
as an encoded Entry never re-derives it, so an object written with a zero
FileSize kept its real size only in the chunks, and stripping them left
the client reading the file as empty. Stamp the size into the attributes
first, which costs nothing and does not depend on how the store loaded
the entry.

* mount: test that the readdir context reaches the store decode

Everything else exercises the decoder directly, so a refactor that
stopped threading the context would have reverted the whole thing with
every test still passing.

The benchmark's chunks also carried a constant legacy FileId, which
BeforeEntrySerialization reparses over Fid on the way in, so all 200k
entries stored one byte-identical chunk rather than the varying fixture
it looked like.

GetVolumeIds, which ranges over a map and is correct, is what ToDiskInfo and

* perf(weed/topology): preallocate the node's volume concatenation

A node's volumes are gathered per disk and concatenated into a slice grown from

writable-volume refresh loop does this for every node every few seconds.

Sizing it to len(actualVolumes) instead would allocate the whole list on every

After the deletion pass everything left on the node is also in this heartbeat,
so the difference is exactly what the node is about to gain: all of them on a
reconnect, none in steady state.

Chris LuandGitHub 8aa57bef78 mount: stop churning the inode table on every readdir (#10606)
* mount: readdir enters a child in the inode table only when it takes a reference

Only readdirplus into the kernel takes a reference on the children it
reports, and only that reference brings a FORGET later to take the entry
back out. Every other listing was inserting all its children anyway.

On WinFsp that meant a listing looked each child up, took a reference,
and immediately gave it back, so a walk of a wide directory paid three
write-lock acquisitions per entry to leave the table exactly as it found
it. On a plain kernel readdir nothing gives the entry back at all, so
listing a directory of 200k files grew both maps by 200k entries that
were never reclaimed.

A dirent's inode number is informational either way: the kernel must
LOOKUP before it can use a nodeid, and the WinFsp adapter re-resolves
every operation by path. So report the number and let the mapping be
built when something actually looks the entry up.

* mount: take the readdirplus reference without a second full lookup

The entry has just been resolved a few lines above, so redoing the whole
lookup only rebuilds the child path and walks both maps again to reach a
counter. Bump it directly, falling back to the full lookup if a Forget
removed the entry in between.

* mount: benchmark a readdir over a 200k directory

Drives doReadDirectory against a meta cache holding 200k entries, one
round of 4096 at a time, for the three front ends that behave
differently: a plain kernel readdir, kernel readdirplus, and a WinFsp
listing that gets attributes but never returns a reference. Reports what
each leaves behind in the inode table alongside the usual metrics.

The sink declares TakesLookupRef as an ordinary method rather than
through the interface, so the same file runs unchanged against an older
tree for comparison.

* mount: stamp an inode on the benchmark's entries

The filer stores one on every entry it writes, so a real listing arrives
with an inode and never derives its own. Leaving it zero made every child
in the benchmark fall through to the MD5 in AsInode, work no filer-backed
mount does, and charged it to both sides of the comparison.

Chris LuandGitHub ee54fd6c08 perf(weed/storage/super_block): intern the byte-encoded replica placements (#10610)
NewReplicaPlacementFromByte formatted the byte with fmt.Sprintf and parsed the
result back, allocating a string and a ReplicaPlacement every call. The master
calls it once per volume in every heartbeat, and keeps the pointer for the
lifetime of the volume, so a cluster with 1.6M volume replicas carries 1.6M of
these where a handful of distinct values exist.

The table is a flat pointer-free array, so it costs 6KB of static data and no
heap objects however few placements a cluster actually uses.

A byte only ever decodes to a valid placement, so the table is complete and the
error return stays nil.

Chris LuandGitHub fb92d46e2d helm: enterprise license Secret, and a persistent-claim option for master data (#10601)
* helm: mount an enterprise license Secret into every component

Running the enterprise image under this chart meant hand-rolling
extraVolumes and extraVolumeMounts on every component. Missing one is
easy and quiet: a component without the license silently drops to
community mode, and on the admin that surfaces only as Data Recovery and
Point-in-Time Recovery refusing to enable, with the master looking fine.

Add global.seaweedfs.license.existingSecret. The Secret is mounted
read-only into master, volume, filer, s3, sftp, admin, worker and
all-in-one, and SEAWEED_LICENSE points every process at the file rather
than relying on the binary's search paths, which depend on the working
directory.

The mount is a directory, never a subPath: kubelet refreshes Secret
contents in place, but a subPath is resolved once at container start and
never updates, which would break license renewal. There is deliberately
no checksum annotation on the pod template either — that would roll every
pod on renewal, the opposite of what is wanted. Verified on kind: the
renewed file reached a running master ~70s after the Secret was patched,
same pod UID, restartCount 0.

Also documents that only the master re-reads the license on a timer
today; the other components pick a renewal up on their next restart.

* helm: keep master data on a claim by default

The master's -mdir holds its Raft log and snapshots, and with them the
cluster's topology UUID — the identity an enterprise license is issued
against. It defaulted to a hostPath under /ssd, which does not follow a
rescheduled pod: the master came back with an empty data directory, a
freshly generated cluster UUID, and a license that no longer matched.
With the chart's default of a single master replica there is no peer to
recover the identity from either.

Default master.data.type to persistentVolumeClaim, sized 1Gi (Raft state
is small). hostPath stays available for anyone who wants it.

This is breaking for existing releases: volumeClaimTemplates is immutable,
so helm upgrade on a release installed with the old default fails with
"updates to statefulset spec for fields other than ... are forbidden".
Verified on kind, along with both ways out — pinning
master.data.type=hostPath upgrades cleanly, and the documented migration
(stop the master, pre-seed a claim named after the StatefulSet, upgrade)
preserves the cluster UUID. Seeding has to happen while the master is
stopped; copying into a live pod loses the state, since the running
master rewrites its Raft files before the restart.

* helm: mount the license on masters only

The master is what reads the license file: it validates it, enforces the
capacity limit and binds it to the cluster UUID. Mounting the Secret on
volume, filer, s3, sftp, admin and worker put it in six more containers
that never look at it, so drop it there and keep master plus all-in-one,
which runs `weed server -master`.

Two fixes from review while here:

  - project only the configured key out of the Secret, so an unrelated
    key in the same Secret is not exposed to the container. Verified the
    key-scoped projection still updates in place: patching the Secret
    reached the running master in ~50s, same pod UID, restartCount 0.
  - drop SEAWEED_LICENSE from merged extraEnvironmentVars while a
    license Secret is configured. It used to be possible to render the
    key twice in one container, with the user's value winning over the
    path the chart actually mounts.

CI now pins the scope (master only, all-in-one separately), the
key-scoped projection, readOnly, and that SEAWEED_LICENSE renders once.

* helm: fix the documented master-data migration

The seed pod in the migration never mounted the claim it was supposed to
seed, so following the steps verbatim copied the Raft state onto the
pod's ephemeral filesystem and threw it away with the pod — landing the
reader in exactly the empty-claim, new-cluster-UUID state the section
exists to avoid. Give the pod the volume.

The names were assembled as <release>-seaweedfs-*, which is wrong
whenever the release name already contains the chart name or an override
is set; read the StatefulSet name from the cluster instead and derive the
claim from it. Also scope the procedure to the chart's single-master
default, and create the Secret in the release namespace.

Trims the enterprise prose this section had accumulated: this is the OSS
chart, and the master-data default is a durability fix that stands on its
own.

* helm: quote the projected license key, reserve it on the secret env path

A secretKey that YAML reads as a non-string (123, yes, no) rendered
unquoted into the volume's items, so the projection would not match the
Secret's key. Quote both key and path.

all-in-one renders secretExtraEnvironmentVars itself, outside the merge
helper that already drops SEAWEED_LICENSE, so an entry there could still
render the variable twice. Skip it there too while a license Secret is
configured. The master template has no such block, so this is the only
remaining path.

* helm: correct the license helper comments after scoping to masters

* helm: keep hostPath as the master data default

Defaulting master.data.type to a claim broke every existing release:
volumeClaimTemplates is immutable on a StatefulSet, so helm upgrade
failed with "updates to statefulset spec for fields other than ... are
forbidden" before it changed anything.

Keep hostPath as the default and document the claim as the option to
choose — for a new install, or for an existing one via the migration
already in the README. The chart supported both types all along; only
the default moves back.

Every immutable field of every rendered StatefulSet is now identical to
upstream under default values, so an in-place upgrade cannot trip the
API. Verified on kind: install with the unmodified upstream chart,
upgrade to this branch (ok), upgrade again turning the license Secret on
(ok, volume added in place). A fresh install with
master.data.type=persistentVolumeClaim binds its claim as before.

The whole PR is additive now: nothing renders differently until a value
is set.

* helm: scope the migration's StatefulSet lookup to the release

* helm: trim the comments added by this change

Chris LuandGitHub a8c8372b99 rust: stop quarantining v2 volumes, load a disk's volumes concurrently (#10602)
* rust: only compare the .dat tail on v3 volumes

Go's verifyNeedleIntegrity does the "does .dat end exactly at the last
indexed needle" comparison inside its v3 branch -- it rides along with
the v3 append-timestamp read -- so a v1/v2 volume carrying an unindexed
trailing record loads read-write and silent. The Rust check ran it at
every version, so booting the Rust server on a legacy cluster warned on
and quarantined volumes the Go server had been serving happily.

* rust: load a disk's volumes concurrently

Opening a volume is dominated by reading its .idx into the needle map,
and the loader did them one at a time, so a disk holding thousands of
volumes needed thousands of serial index reads before the server came
up. Go's concurrentLoadingVolumes spreads the same work over
max(cores, 10) workers; do the same, keeping the directory pre-pass and
the insert serial so only the open is parallel.

* rust: let a failed volume open fall back to the next candidate

Two collections can name the same volume id on one disk. Deduping the
load queue by id claimed the id for whichever candidate the scan saw
first, so a corrupt one shadowed a good one behind it; the serial loader
this replaced only claimed an id once a volume had actually opened.
Carry every claiming collection per id and try them in scan order until
one loads.

* rust: trim the new comments in the volume loader

Chris LuandGitHub 0cf62a921a admin: dashboard counts chunks, not files (#10598)
* admin: count each chunk once in the dashboard total

The dashboard summed file_count from every node's volume list, so a chunk
was counted once per replica and deleted chunks were never subtracted.
Reuse the collection aggregation, which dedupes replicas and EC shard
holders and nets out tombstones.

* admin: the dashboard card counts chunks, so name it that

Volumes store chunks, and a file is split into one or more of them, so
the 'Total Files' card always read far higher than the number of files in
the filer. Rename it to 'Total Chunks' and say so in the tooltip.

* admin: collections pages count chunks once and say so

The collections list and detail pages summed file_count straight off the
topology, so replicas multiplied the count, tombstones stayed in it, and
the detail page ignored EC volumes entirely. Take the numbers from the
shared collection aggregation and label them chunks.

* admin: dedupe replica chunk counts per volume instead of dividing

Dividing each replica's live count by the copy count truncated a chunk
per odd-sized volume, and reported half the count while a volume's
second replica had not checked in yet. Replicas mirror each other's
needles and deletes, so keep the fullest report per volume id.

* admin: fix the collections CSV export column mapping

The exporter read chunks from the EC-volume cell and shifted size and
disk types with it. Read every column the table actually has.

Andrei StroianandGitHub aa04889f05 fix(helm): mark filer db-init ConfigMap volume optional (#10596)
The filer StatefulSet declares db-schema-config-volume unconditionally, referencing <release>-seaweedfs-db-init-config. The chart never renders that ConfigMap and the README documents it as operator-supplied, so any deployment that has not pre-created it ends up with a pod spec pointing at a non-existent object. No container mounts the volume, so this is currently inert, but it is misleading and would become a pod-start failure if a volumeMount is ever added.

d1f503181b [s3] force filer apply s3 expiry metadata (#10469)
* fix: apply S3 Expiry Metadata

* add test Header X-Seaweedfs-Expires-S3

* resolve comments

* test entry lookup by mtime

* filer: skip s3 expiry stamp on versioned entries

The s3 expiry path skips entries carrying a version id, so stamping one
takes away its expiry rather than moving it onto mtime. Files under
.versions/ are written once, so crtime already tracks their needles.

Chris LuandGitHub a5e8254ffd s3: give a versioned metadata-only copy its own chunks (#10594)
* s3: give a versioned metadata-only copy its own chunks

A self-copy that only rewrites metadata clones the source entry, chunk fids
and all, and writes the clone back. With no versioning that is exactly right:
the clone replaces the entry it came from, so one entry owns the needles the
whole time. Under versioning the clone lands in a new .versions/ file and the
source stays live, and nothing refcounts a plain shared chunk list -- deleting
either version (a NoncurrentVersionExpiration rule, say) frees needles the
other still points at, and the next vacuum makes that permanent. rclone hits
this on every upload, since it stamps mtime with exactly this copy.

Take the metadata-only path only where the write replaces the entry it read:
the bare key of a bucket without versioning. Versioned, suspended, and
versionId-pinned copies fall through to the regular copy path, which gives the
destination its own chunks.

* s3: reencrypt a versioned SSE-KMS key rotation instead of reusing the chunks

A same-object copy that changes the KMS key id hands the source chunks straight
back, on the assumption that the copy overwrites the entry they came from. A
versioned bucket writes a new version beside the source instead, so the two end
up sharing needles that nothing refcounts, and deleting either one frees the
other's data. Reuse the chunks only when the destination really is the source
entry; otherwise fall through to the reencrypt path, which also gives the new
version the key it asked for rather than leaving it on the old one.

* s3: make one predicate decide whether a copy replaces its source

The metadata-only branch and the key-rotation strategy both answer the same
question -- does this copy write back to the entry it read -- so let them share
one predicate instead of pairing a same-destination check with it separately at
each site.

* test(s3): fail the copy regression tests when the vacuum does not run

The helper swallowed a failed or non-200 request to the master, so a vacuum
that never ran turned both chunk-ownership assertions into no-ops: the
tombstoned needles were still readable and the surviving version looked fine
either way. Require the endpoint, the request, and a 200.

* ci(s3): run every versioning test in the regression gate

The gate named the tests it wanted, so a new regression test sat there
uncovered until someone remembered this file -- it fooled me into thinking two
tests added in this PR never ran anywhere, when the comprehensive job had them
all along. Invert it: run everything, and name a test only to keep it out. The
delete job beside this one already works that way, and the suite costs about
two minutes.

Only the pagination stress tests are excluded; they build 1500+ versions, skip
themselves without ENABLE_STRESS_TESTS, and have their own make target.

Go's regexp has no negation, so the pattern is still assembled from a listing,
the way the volume-server integration workflow does it. Note the trailing $$:
make eats a lone trailing $ and takes the anchor with it.

ab79d1f680 operation: re-assign chunk upload when replica volume is full (#10588)
* operation: re-assign chunk upload when replica volume is full

When a volume reaches MaxPossibleVolumeSize, needle writes return
'Volume Size Exceeded' and the fan-out in uploadChunkToHolders fails.
Previously the error propagated immediately, killing the entire chunked
upload even though the master has other writable volumes.

Fix: detect 'Volume Size' errors on the fan-out path, call AssignFunc
again to get a fresh volume, and retry (up to 3 attempts). This avoids
backup failures while a single replica volume is full and waiting for GC.

Also add 'volume size exceeded' to the transient error messages so any
retry path that checks IsTransientError recognises it.

* util: fix transient error pattern for volume size errors

The actual error message is 'Volume Size 34361499680 Exceeded 34359738368'
where the numeric size separates 'Volume Size' from 'Exceeded'. The
previous pattern 'volume size exceeded' would never match. Change to
'volume size' which correctly matches any capacity-full error.

* operation: fix reassignment loop nits

- Case-insensitive volume size match (strings.ToLower)
- Propagate AssignFunc error so caller sees reassignment failure
- Reset JWT fallback before each reassignment to avoid retaining stale auth

* util: stop classifying a full volume as a transient error

A volume at capacity does not become writable on the next attempt, so the
entry only bought a retry loop's worth of sleeping before the same failure.
It also reached four consumers that all retry the same target — the deletion
queue, the replication sink, volume lookups, and Retry/MultiRetry — none of
which reassign, and the widened "volume size" substring swallowed the
replica-receive rejection from WriteNeedleBlob too.

The chunked upload path recovers by asking for a different volume instead.

* operation: reassign a chunk with the shared upload gate

shouldReassignUpload already answers this question for the non-chunked path,
keyed off the status the volume server returned rather than its message text.
Reusing it covers a lost replica peer and an unreachable target as well as a
full volume, and it stops a 4xx from being retried on a second volume that
would reject it identically.

Pulling the single attempt out into uploadChunk keeps the retry loop readable
now that it wraps both the fan-out and the relay path.

* test: cover chunk reassignment across volumes

Pins the three outcomes the gate decides: a full volume moves the chunk to a
fresh assignment, a 4xx stays put, and the loop gives up after
chunkAssignAttempts volumes.

* operation: roll back the fid a reassigned chunk abandons

ReplicatedWrite commits the needle locally before it replicates, so a 5xx can
leave a copy behind on a volume the chunk is about to walk away from. Nothing
will ever reference that fid, and an unreferenced needle is not garbage vacuum
can find — it is dead space until the volume is destroyed.

uploadChunkToHolders rolls back only the holders that reported success, which
misses the one whose write landed but whose response did not, and the relay
path had no rollback at all. Delete from every holder of the abandoned
assignment instead; deleting a needle that never landed is a no-op.

* operation: stop the reassignment loop from multiplying work

retriedUploadData already retries a chunk three times against the same URL, so
wrapping it in three assignments made nine POSTs for one chunk. On the relay
path that inner retry is redundant — the loop retries everything it would, and
on a different volume — so cap it at one attempt per assignment and leave the
budget where it was. The fan-out path keeps its inner retries: absorbing a blip
on one holder beats cancelling the rest and re-uploading the whole chunk.

Nothing bounded any of it by time. weed/s3api passes context.Background() so a
chunk survives client disconnect, which also means no deadline cuts the loop
short, and a chunk goroutine holds one of four buffer slots while it spins.
Break out once another chunk has already failed the object.

* operation: keep the reassignment gate's inputs deterministic

uploadChunkToHolders reported whichever holder error won the channel race.
That was cosmetic while the value was only logged; now it decides whether the
chunk moves to another volume, so a 400 and a 500 arriving in either order
made the retry behavior depend on scheduling. Prefer an error the caller can
act on, and the same failure always retries the same way.

A failed reassignment also overwrote the upload error that prompted it, which
buried a full volume behind whatever the filer happened to say. Keep both in
the chain.

The tests grew a JWT per assignment, since the loop re-derives one and nothing
covered it, and the bound is now spelled out rather than compared against the
constant that defines it.

* operation: roll back the last abandoned fid too

The rollback ran only on the path that goes on to reassign, so the attempt
that exhausts the budget — or stops because another chunk already failed the
object, or because the error is not one a different volume fixes — left its
fid behind. That is the case that matters most: no chunk names it, the caller
gets no fid to clean up, and a 5xx can still mean the needle was committed.

Roll back on every failed attempt instead, before deciding whether to retry.

Chris LuandGitHub e8020910db iam: authorize IAM management actions as IAM actions (#10593)
* s3: keep a non-S3 action out of the request-shape resolver

ResolveS3Action reads the request shape before it looks at the base action, so
an iam: or sts: action on a request that happens to carry an S3 query parameter
came back as the S3 action for that parameter. An action that already names its
service is resolved; there is no S3 request shape to read for it.

* iam: authorize the standalone IAM server's actions as IAM, not as S3

The standalone `weed iam` server wrapped its single POST / route in the generic
S3 Auth middleware with ACTION_ADMIN. The route has no {bucket}, so the check
ran with an empty bucket and resolved to a coarse S3 action rather than the IAM
one. The embedded IAM surface checks iam:<Action>; the standalone one was never
updated to match.

Both now go through one authorization function, so they cannot drift apart
again. It also rejects the anonymous identity, which has no user of its own to
run a self-service action against, and reads UserName from the body only, where
the handlers read it from.

Chris LuandGitHub c2b47967bd s3: retire the suspended null marker only once the PUT has committed (#10589)
The suspended PUT dropped the null delete marker before writing, so a failed
write left the .versions pointer naming a marker that was gone. The read path
heals a dangling pointer by promoting the newest survivor, so a key the caller
had deleted came back serving an older version, and the heal persisted that
pointer. Move the retire into afterCreate via the shared finalize, which also
brings the ownership check the copy and multipart paths already have.
