Chris LuandGitHub 1e1b2bb2f9 iceberg maintenance: record file counters on the snapshots it commits (#10420)
A maintenance snapshot carried only its own labels — merged-files,
delete-groups and friends — and no summary counters, so every engine that
reads a table's size out of the current snapshot summary reported nothing
for it: PyIceberg's inspect.snapshots, Trino's $snapshots and Spark's
DESCRIBE all read total-records, total-data-files and total-files-size
verbatim, and a table lost them the moment compaction touched it.

Accumulate the files each operation adds and removes, and render them the
way the spec defines: the added-*/removed-* counters from the files
themselves, then the totals carried over from the parent snapshot.

Carry a total only when the parent recorded it. Iceberg treats a missing
total as zero, which turns a compaction replacing two files with one into a
negative total-data-files, or a table with millions of rows into
total-records: 0. Leaving the field out lets a reader fall back to the
manifests instead of believing a made-up number.

Compaction also accounts for the delete files it consumes, so a run that
folds every delete into the rewritten data reports them as removed.

Chris LuandGitHub b4b0346f95 iceberg maintenance: resolve table files from the recorded location (#10418)
The worker assumed every file of a table sits under its catalog path, so
loadFileByIcebergPath stripped the scheme off a recorded location and joined
the remainder onto /buckets/<bucket>/<ns>/<table>. A table the REST catalog
placed elsewhere in the bucket — which is what a client gets whenever the
catalog path is already occupied — then resolves to a doubled path:

  lookup /buckets/lake/source/t/lake/source/t-0cd81bca-.../metadata/snap-.avro

so the very first manifest list read fails and the job fails again on every
scan interval, indefinitely.

Resolve absolute references (s3:// URIs and /buckets paths) from the bucket
root and keep relative ones under the table's own directory; the
bucket-relative form is now the canonical key everywhere references are
compared. That directory comes from the metadata location the catalog stores,
so reads, writes and deletes all land where the table's other files are
instead of splitting it across two trees. References outside the table's
bucket are rejected rather than silently misresolved.

Rewritten position-delete files now name their data file by absolute URI,
the way the table itself names it, instead of a path relative to the table.

Chris LuandGitHub 6e6255b58e shell: accept a context in the volume move helpers (#10415)
LiveMoveVolume and the copy, tail, delete, mark, replicate, and
configure helpers around it issued every RPC on context.Background(), so
a caller had no way to bound or abort a move once it started. They now
take a context, which the exported LiveMoveVolume in particular needs:
callers outside the shell drive long moves and want to stop them.

The deferred restore in copyVolume runs on a detached, bounded context
rather than the caller's. Marking the source writable again is cleanup,
and cancelling the copy must not skip it and leave the volume readonly —
the same guard balance_task.go already applies for the same reason.

Shell commands pass context.Background(): their Do signature carries no
context, and changing it would touch every command in the package.

Chris LuandGitHub 47b491b53c mount: version open file handles by filer log position (#10403)
* filer: stamp a log position on lookup and remote-cache responses

Metadata events are logged after their store write and stamped with the
filer clock. Reading that clock before serving an entry therefore gives
a timestamp with a causal guarantee: every event at or below it is
reflected in the returned entry. Clients caching filer state can use it
as the entry's version to order the response against subscription
events, including events committed before the call but delivered after
it.

* mount: version open file handles by filer log position

A subscription event refreshing an open handle did a second lookup; a
transient failure left the handle pinned to its old entry with no
retry, since the subscription cursor had already advanced. The deeper
problem is ordering: the handle is a cache written by three unordered
channels — the async invalidation worker, local mutation acks, and
open-time lookups — and overwriting cached state safely requires
knowing which write is newer.

The filer log timestamp is that order, and it now travels with every
value instead of being derived out of band. Events carry it natively;
lookup and remote-cache responses carry the log position stamped before
the serving read; mutation acks carry it in their returned event; and
the local store pairs each read with a version cursor advanced under
the same lock as the store write. Each handle records the version its
entry reflects, and one rule replaces the per-site reasoning: state at
or below the handle's version is old news and must not be installed.

The invalidation itself applies the event's own entry — no lookup, so
no transient-failure window — except under a cached parent, where the
store entry is the ordered merge of the event and anything applied
since, and its version outranks the event's. An uncached parent
receives no store writes, so a hit there would be a stale leftover
masking the event. A vacated path (delete, rename away) keeps the last
entry so unlinked-but-open reads still work. Directory builds version
the completed directory at the listing snapshot and re-invalidate
buffered events at that version, since their mid-build refresh ran
against an incomplete store.

The tests replay every race this replaces machinery for: rollback of a
newer local flush (queued, cached, and read-through), stale leftovers
under uncached parents, the build window including abort, handles
opened after an event was queued, events landing mid-lookup, and
undelivered events at remote-cache time across a filer failover.

* filer: serialize the log position fence with mutations, stamp mutation acks

The fence stamped before an unlocked entry read could precede state the
read returned: a mutation writes storage first and assigns its event
timestamp only at notify time, so a lookup racing that window handed
the mount an entry newer than its fence, and the event's later delivery
looked like fresh news — destroying dirty pages for a change the handle
already had. The mutation handlers already hold an exclusive per-path
lock across read, write, and notify; the lookup and remote-cache reads
now take it shared around the stamp and the read, making the fence
exact: everything at or below it is in the entry, nothing above it is.

A no-change update returns success without an event, leaving the mount
nothing to fence with even though the response confirms current state.
Create and update acks now carry a log position stamped under the same
lock, and the mount falls back to it whenever the ack has no event.

Also regenerate the VT marshalers, which the earlier generation missed:
without them a VT round-trip silently zeroed every log position.

* java: sync filer.proto

* mount: scope store versions to what they vouch for; atomic handle install

The store's version cursor claimed too much. Advanced by local mutation
acks and directory listing snapshots, it inflated the version of store
reads for unrelated paths whose events the subscription still owed, and
those events were then fenced out permanently. The cursor now tracks
subscription progress only — events arrive in log order, so everything
at or below it has been delivered for every path — and a completed
listing records its snapshot as a per-directory floor instead of a
global claim. Local acks never touch it: they version their own handle
directly. Buffered build events advance the cursor at delivery, since
their store write may never happen (abort) while their invalidation is
already queued; their read-through directory pairs no store read with
it, and rename fragments are applied first.

Concurrent first opens raced: a slower opener's older lookup could
overwrite the newer entry a faster opener had installed, while the
monotonic version kept the newer timestamp — an old entry fenced at a
new version, immune to every correcting event. Entry and version are
now installed as one decision under the handle map lock, and an install
that does not outrank the handle's version is dropped.

The remote-cache commit also escaped the fence: it wrote storage and
notified without the path lock, so a lookup's shared-locked fence and
read could land between the two and hand out the cached state
under-versioned. The commit now re-reads and writes under the exclusive
path lock, and backs off entirely when the entry changed during the
download — the concurrent writer supersedes the cached content.

* mount: floors gate store applies; installs respect handle users; renames join the fence

A directory floor certifies the listing state as of its snapshot, but a
delayed event at or below the floor was still applied to the store —
rolling the content back to pre-snapshot state while the floor kept
claiming the snapshot version, so the correcting events were fenced out
of every future read. Events are now gated against the affected
directory's floor, each half of a rename independently.

Fences are lower bounds: a listing or lookup can include a mutation
whose event has not been delivered yet, and that event later passes
every gate carrying state the handle already holds. Such a re-delivery
now advances the version without destroying dirty pages or reinstalling
the entry — invalidating local writes over a no-op was the real damage
in every remaining under-fence window, including the unlocked listing
snapshot, which no per-path lock can serialize.

The concurrent-open install moved from the map lock to the handle lock
every reader, writer, and invalidation synchronizes on, and rejects
what cannot improve the handle: dirty state (local writes would be
lost), unversioned lookup responses (they cannot outrank anything, and
two zero-version opens must not overwrite each other), and anything not
strictly newer. New handles are still fully initialized before the map
exposes them.

Renames committed metadata and emitted events with no path lock, so a
lookup could read the renamed state under a fence preceding its events.
Both rename handlers now hold the source and destination locks, ordered
by path, across commit and notification; descendants of a renamed
directory are not individually locked and rely on the no-op re-delivery
handling above.

* mount: per-entry store versions replace the cursor and directory floors

The store's aggregate versions — a global subscription cursor and
per-directory listing floors — were versions at coarser granularity
than the values they described, and every over-claiming bug in this
series traced to that gap: an aggregate vouching for state its source
never saw. Each store entry now carries the filer log position of the
write that produced it — the event that applied it, or the listing
snapshot that inserted it, recorded in the store's key-value space
under the same lock as the entry write. The store becomes what the
handle already is: a last-writer-wins register with one rule, install
only what outranks the current claim.

The cursor, the floors, their advancement rules, the pairing ordering
constraint, and the floor gating all collapse into that rule. Applies
are gated per entry, each half of a rename independently; an
unversioned local write clears the claim its content no longer proves;
version records lingering after a bulk folder wipe cannot fence a
recreate, since a claim only blocks while its entry exists. Listing
inserts are stamped at build completion, before the buffered replay so
newer replayed events override the stamp.

Filer side, the fence dance every versioned read must perform is now a
single choke point, fencedFindEntry, so a future read RPC gets the
lock-serialized stamp by construction rather than by convention.

* mount: judge no-op re-deliveries against an immutable base, not the live entry

The equal-state skip compared the incoming event to the live handle
entry, but local writes mutate the live entry — size, timestamps,
chunks — so a delayed event re-delivering the base the handle was
opened with no longer matched, and the installer destroyed the dirty
pages and rolled the entry back over nothing new. The handle now keeps
an immutable snapshot of the filer state it last installed or
acknowledged, refreshed at every install and mutation ack (flush acks
snapshot the request entry before the id mapping mutates it), and the
no-op judgment runs against that base: an event carrying the base
brings nothing, whatever the live entry has diverged to since.

* mount: tombstones for versioned deletes, absence floors, copy enrollment

Four gaps in the per-entry version protocol, all the same shape: a
versioned fact with nothing carrying its version.

A deletion is a fact about a path with no entry left to hold it —
clearing the record let a delayed older event resurrect the deleted
path, permanently, since the deletion's own redelivery is
dedup-suppressed. Versioned deletes now leave a tombstone record that
fences without an entry; renames tombstone their source the same way.
Plain records still only block while their entry exists, so records
lingering after a bulk folder wipe cannot fence a recreate.

A completed listing proves absences as well as presences: a name it
omitted was deleted as of the snapshot, and a delayed create below the
snapshot re-creates it. The snapshot is kept per directory strictly as
an absence fence, consulted only when a path has neither an entry nor
a version record — present entries carry their own versions and never
touch it, which is what separates this from the over-claiming floor it
replaces.

A rebuild against a pre-upgrade filer returns no snapshot; stamping
now clears the children's records in that case, so a reinserted entry
cannot reactivate the stale claim its previous incarnation left
behind and reject valid events below it.

Server-side copies installed the copied entry without enrolling in the
base protocol, so the copy's own event differed from the stale
pre-copy base and destroyed writes made to the destination after the
copy. The install now refreshes the base and takes its version from
the fenced readback.

* mount: deletion facts outlive the cache's knowledge of the entry

A versioned delete of a path the store held no entry for recorded
nothing, so a delayed older event recreated the path — permanently,
with the deletion's redelivery dedup-suppressed. The tombstone is now
written whenever a versioned event vacates a path: the deletion is a
fact about the path, not about what this cache happened to hold.

For an absent entry, the listing's absence floor now speaks whatever
older record remains: a tombstone at one position does not exhaust
what is known about the path when a newer snapshot has confirmed the
name still absent, and an event between the two was slipping past
both.

A committed copy whose readback failed installed a synthesized base
with local timestamps; the copy's real event legitimately differs from
it, and was read as foreign state — destroying writes made to the
destination after the copy. The handle now marks that its own event is
en route and adopts that event's state as the base without touching
the live entry or the dirty pages; the adoption is one-shot, so a
genuinely foreign event still invalidates.

* mount: authoritative acks cancel pending event adoption; tombstones scoped and pruned

The copy-event adoption flag could outlive its purpose: a flush after
the failed readback installs a newer base and advances the version, the
copy's own event is then version gated without consuming the flag, and
the next genuinely foreign event was silently adopted — base advanced,
live entry and dirty pages untouched — leaving the mount to later
overwrite that remote change. Every local acknowledgment now installs
its base through one helper that also cancels any pending adoption: the
ack supersedes the mutation the adoption was waiting for.

Tombstones were written for every versioned delete under the mount and
survived directory eviction by design, growing LevelDB with historical
deletions on delete-heavy mounts. They are now scoped to directories
whose cached state the fence actually protects — an uncached parent
never serves from the store nor applies the resurrecting insert — and a
completed listing prunes the direct-child tombstones its absence floor
supersedes, leaving only those above the snapshot. The store gains a
key-prefix visitor for the sweep.

* mount: acked saves install their value; trailer snapshots; direct-child prune range

A version must never advance without its value. saveEntry stamped any
open handle with the acknowledgment's version, but a handle opened
while the save was in flight holds the pre-mutation entry — stamping it
fenced out the events carrying the state it lacked, permanently, with
the local apply performing no invalidation and the redelivery
deduplicated. The acknowledged entry is now installed together with its
version, through the same guarded install the racing-open path uses:
under the handle lock, only when it outranks the handle, never over
dirty local writes.

Empty listings return no in-band snapshot — a snapshot-only response
would be read as an entry by older consumers — so directories that end
empty gained no absence floor and their tombstones were never pruned.
The filer now sends the snapshot in the stream trailer, which older
clients ignore, and the client reads it when no in-band snapshot
arrived. Empty directories get real floors, their tombstones prune,
and their buffered replays gain the snapshot filter instead of the
replay-all fallback.

Version records now encode the parent directory and name separated by
a NUL, making a directory's direct children one contiguous key range:
the tombstone prune scans exactly them under the cache lock, instead
of walking every descendant record — the whole store, for root.

* mount: fix dirty-page loss, uid/gid base, download race, copy adopt, leak; dedup

Correctness fixes from the versioned-invalidation review:

- A foreign delete/rename-away of a file held open with unflushed local
  writes destroyed the dirty pages unconditionally. A process may keep
  writing to an unlinked-but-open file and those writes were already
  acknowledged; preserve the pages when the handle is dirty.
- downloadRemoteEntry stored the handle's base with filer-side uid/gid
  while every candidate it is later compared against is in local form,
  so under a non-identity UidGidMapper an unchanged re-delivery looked
  foreign and force-destroyed dirty pages. Map the base to local.
- downloadRemoteEntry wrote the entry/base/version triple under only the
  handle's shared lock, so two concurrent reads of the same remote-only
  file could tear it. Serialize the install with a dedicated mutex
  (invalidation is already excluded by the exclusive handle lock).
- A committed server-side copy whose readback failed adopted the FIRST
  event past the version gate as its base; a foreign write delivered
  first was silently swallowed. Adopt only an event whose content
  matches the synthesized base — the copy's own event — and install any
  other normally.
- The deferred-create path relied on AcquireFileHandle installing the
  passed entry on a pre-existing handle, which the version rework
  dropped. Restore that install in the compat wrapper; the versioned
  open path keeps its gated install.

Growth and hot-path cost:

- Per-entry version records and tombstones leaked when a directory was
  evicted or read-through without a rebuild. An uncached directory
  gates its own inserts, so its records fence nothing; clear a
  directory's child version records when it is wiped for eviction.
- FindEntry paid for the version KvGet on every lookup/getattr cache hit
  and threw it away. FindEntry now reads only the entry; the hot
  lookupEntry cache-hit path skips the version entirely.

Cleanups:

- Extract ackVersionTsNs over the shared response interface, replacing
  the metadata-event-else-log-ts snippet copy-pasted at four ack sites.
- Extract acquireRenamePathLocks, replacing the verbatim sorted
  two-path lock fence in both rename handlers.

* mount: no resurrection on foreign delete, version no-event acks, gate downloads, tighten copy adopt

Follow-ups to the review patches:

- Preserving dirty pages on a foreign delete let the next flush pass the
  isDeleted guard and CreateEntry, resurrecting the remotely-unlinked
  name. Mark the handle deleted in the vacate branch: the open fd can
  still read its buffered writes, but a flush no longer recreates the
  file.
- A no-event acknowledgment (log fence only) synthesized a metadata
  event with TsNs 0, so the cache stored the entry unversioned and an
  older subscriber event rolled it back. Stamp the synthesized event
  with the ack's log position at all four ack sites.
- downloadRemoteEntry serialized its install but did not check the
  version, so an older response arriving last overwrote the entry/base
  while the monotonic version kept the newer value, fencing corrections
  out. Install only when the response is at least as new as the handle.
- sameEntryContent compared only size and chunks, so a foreign chmod
  with unchanged content was adopted as the copy's own event. Compare
  everything except server-assigned timestamps, so a metadata-only
  foreign change installs instead.

* mount: trim comments to the non-obvious why

The versioning work accumulated multi-line comment blocks restating what
the code says. Keep the constraint a reader cannot derive — why a fence
is exact, why a version must not advance without its value, why an
uncached parent's records fence nothing — and drop the rest.

* mount: distinguish rename from delete, tighten the download and adopt gates

- A rename emits a nil old-path invalidation just like an unlink, so the
  vacate branch marked the handle deleted and later writes through the
  already-open descriptor were skipped instead of persisted. Carry the
  delete/rename distinction on the invalidation and mark only an actual
  delete.
- The remote-download install accepted an unversioned response
  regardless of the handle's version, so during a rolling upgrade a
  delayed response could install stale content under a newer version.
  Require the response to be at least as new, with one exception: a
  handle still lacking local chunks takes the content anyway — it cannot
  read without it — but does not claim the response's log position.
- Copy-event adoption returned without installing, so a foreign touch
  arriving before the copy's own event lost its timestamps. Content is
  unchanged either way, so the dirty pages stay valid; a clean handle now
  takes the entry, while a dirty one keeps its diverged version.

* mount: one directory floor instead of a record per child; agree on TTL

Review feedback:

- Build completion wrote one KV record per direct child inside the cache
  write lock, so a large directory stalled every other cache operation
  for O(children) store writes. The directory's listing snapshot already
  covers every child it saw; make that floor the version for any child
  without a record of its own, and a child earns a record only when a
  later event touches it. One map write per build replaces the per-child
  writes, with the same fencing.
- The presence probe read the store directly and so counted a
  TTL-expired entry as present, judging the path by a record describing
  content that has logically vanished. It now applies the same expiry
  the read path does, and an expired path falls back to its directory
  floor.
- Preserve ErrNotFound identity when the commit-time re-read finds the
  object deleted, so callers still surface a 404.
- Assert the rename-away source fence timestamp in the invalidation test.

Also record the tombstone ceiling: distinct deleted names in a cached
directory accumulate until it is rebuilt or evicted, which prunes
everything at or below the new snapshot.

* mount: pin the fence's clock domain instead of letting skew decide

A log-position fence is stamped by one filer's clock under that filer's
in-process lock, so comparing it to an event another filer logged is
comparing two unrelated clocks. The two error directions are not equally
costly: applying an event the fence already covered is a re-apply the
base-equality check absorbs, while skipping one it does not cover leaves
the handle holding exactly the state the event was meant to correct,
with the subscription cursor already past it — the unhealable staleness
this whole PR exists to remove.

So refuse to guess. Fences now carry the signature of the filer that
stamped them, and a handle records it alongside the position. An event
is only fenced out when the filer that logged it is the one that stamped
the fence — the logging filer appends its own signature, so its presence
identifies the clock domain. Events from any other filer are applied.
Positions taken from events keep comparing as before; the subscription
already delivers those in order.

The invalidation callback takes a struct now: it carries the path,
entry, position, delete/rename distinction, and signatures, and was
about to need a fifth positional parameter.

* mount: follow a foreign rename; key page invalidation on content, not equality

- A rename's old-path invalidation now carries the destination, and the
  handle follows the file there: an open fd tracks the inode, and leaving
  it on the old path made its next flush recreate that name instead of
  updating the renamed file.
- Dirty pages overlay content, so only a content change invalidates them.
  Keying that on exact equality meant any timestamp-only event destroyed
  them, which the copy-adoption marker existed to paper over — a foreign
  touch could consume the marker and leave the copy's own event to drop
  the post-copy writes. Comparing content instead makes the marker
  unnecessary, so it is gone: a metadata-only event keeps the overlay,
  and a dirty handle keeps its diverged entry unless foreign content
  supersedes it.
- A remote download response that is merely older is now refused even
  when the handle still lacks chunks; only an unversioned one is taken
  (and claims no position), since an older response's content predates
  what the handle reflects.
- A refused or unversioned download no longer publishes to the metadata
  cache, where a zero-position event would clear the entry's version and
  let an older subscriber event roll the cache back.

* mount: page invalidation keys on content alone; unversioned writes claim no position

- sameEntryContent compared everything but timestamps, so a foreign
  chmod, chown, or xattr change counted as a content change and
  destroyed the dirty-page overlay. It was strict only to serve the
  copy-adoption marker, which is gone; its one caller now asks the
  question it actually needs — did the bytes change — so metadata-only
  events leave the overlay alone.
- A rename over an existing file destroys that file, but its open handle
  was left live and still pointed at the name the renamed source now
  occupies, so its flush could overwrite it. MovePath already reports the
  displaced inode; mark that handle deleted.
- An acknowledgment was refused whenever its position was numerically
  lower, even when a different filer stamped the fence it lost to. Two
  known, differing signatures mean unrelated clocks, so the comparison no
  longer applies there; unknown signatures still compare as before.
- A local write with no log position behind it now records that
  explicitly instead of deleting its version record. Absence means the
  directory listing covers the path, which is why the snapshot floor
  applies; local content the listing never saw must not inherit it, or
  the events that would correct it are fenced out.

* mount: widen the existing lookup functions instead of forking WithVersion twins

The versioning work grew a parallel function for every accessor that
needed to return a log position — lookupEntryWithVersion beside
lookupEntry, maybeLoadEntryWithVersion beside maybeLoadEntry,
FindEntryWithVersion beside FindEntry, AcquireFileHandleWithVersion
beside AcquireFileHandle, advanceEntryVersion beside
advanceEntryVersionTsNs, plus a getPbEntryWithVersion wrapper and an
InsertListedEntriesForTest hook. Two names for one operation is two
places to keep in step, and the split let callers pick the one that
happened to compile.

Each pair is now the single original name carrying the position, with
callers that do not want it discarding it. filer_pb.GetEntry returns the
fence its response already carried rather than a mount-side wrapper
re-issuing the lookup, and InsertEntry takes the position its content
reflects rather than a test-only twin that inserted without one.

The one behavioural knot the merge exposed: AcquireFileHandle had been
installing the entry on a pre-existing handle only in its unversioned
form, which conflated 'the caller is authoritative' with 'the lookup had
no version'. Deferred create is the only caller that means the former,
so it now installs explicitly and the map function just acquires.

Chris LuandGitHub fe0a357624 exclusive_locks: clear renew-running flag before dropping isLocked (#10413)
On renewal failure the renew goroutine stored isLocked=false before its
deferred renewGoroutineRunning.Store(false) ran. A concurrent RequestLock
interleaving there reacquires the lease (sees isLocked=false), sets
isLocked=true, then its CompareAndSwap on renewGoroutineRunning fails because
the old goroutine's flag is still set — so no replacement renewer starts. The
lock is then held locally with nothing renewing it, and silently expires on
the master after the lease TTL, admitting a second holder.

Clear renewGoroutineRunning before isLocked on the failure path so the
reacquire path always starts a fresh renewer. Builds and vets clean; no
behavior change on the success path.

490379bff3 Add codespell support with configuration and typo fixes (#10393)
* Add GitHub Actions workflow for codespell on master

* Add rudimentary codespell config

* Tune codespell config: skip generated code, ignore camelCase, whitelist domain terms

Add camelCase/PascalCase regex to ignore common Go/Rust/JS identifiers
like allLocations, publishErr, ReadInside, FlushInterval. Also skip
templ-generated *_templ.go files, and whitelist a handful of
short/domain-specific words (visibles, fo, te, ser, bject, unparseable,
keep-alives, tread, anc, ue) that show up as false positives across the
tree.

* Fix ambiguous typos and protect false positives

Fixes typos that codespell reports with multiple candidate suggestions
(so `codespell -w` cannot auto-apply them), plus one inline pragma and
one config entry to protect legitimate identifiers.

Manual fixes (single correct answer chosen from context):
- pattens -> patterns (5x) in filer/upload/shell flag help strings
- finded  -> found (2x) in tarantool storage.lua comment
- spacify -> specify (2x) in helm chart values.yaml comment
- wether  -> whether in skiplist.go docstring
- simpe   -> simple in mq schema test case name

False-positive protection:
- Add `//codespell:ignore` next to `source GET's` (possessive of HTTP
  verb) in s3api_object_handlers_copy_stream.go
- Whitelist `auther` in .codespellrc — it's a local variable meaning
  "authenticator" in weed/security/tls.go, not a typo of "author".

* Extend codespell ignore list: .git-meta path and thirdparty groupId

Also skip `.git-meta` (scratch dir for commit messages that may contain
typo words verbatim) and whitelist `thirdparty` — it appears as the
literal Maven groupId `org.apache.hadoop.thirdparty` in hdfs3 poms
and cannot be renamed.

6c4eb95a3a fix(admin): implement ApplyPluginConfigFromToml to propagate settings (#10388)
* fix(admin): implement ApplyPluginConfigFromToml to propagate settings to plugin config store

* Update weed/admin/dash/config_toml.go

Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>

* admin: overlay admin.toml onto plugin configs through bootstrap defaults

Creating a config from scratch at startup skipped the descriptor-defaults
bootstrap, so a job type with only worker keys in admin.toml persisted
Enabled=false and RetryLimit=0 and silently stopped running. Overlay
existing configs at startup, and apply the same overlay in
enrichConfigDefaults when the plugin bootstraps a fresh config from
descriptor defaults.

Also place collection_filter in the admin values where workers read it,
map preferred_tags as a string list, and stamp UpdatedAt.

* admin: trim the admin.toml help text and call-site comment

* admin: clamp toml retry values to the int32 range

* admin: fail startup when admin.toml cannot reach the plugin config

The legacy overlay already aborts startup when declared settings cannot
persist; continuing here would let workers bootstrap with stale values.

* admin: fix the retry clamp test on 32-bit

A 32-bit int cannot hold the oversized toml value, so viper returns 0
before the clamp runs.

ca06589d64 volume.fix.replication: add a well-placed replica before deleting a misplaced one (#10364)
* volume.fix.replication: add a well-placed replica before deleting a misplaced one

A misplaced volume with no surplus replica (replica count == copy count) used to have its misplaced replica deleted first, and the replacement copied only on the next pass. That drops the volume below its intended durability, and permanently so when no destination can accept the replacement copy. Now such volumes get a well-placed replica first, and the misplaced one is trimmed as surplus on a later pass, following the same fulfill-before-delete principle as volume.tier.move (#8950).

The classification switch is extracted into classifyReplicaSet so the add-wins-over-trim priority is unit-testable.

Also stop the fix loop when an -apply pass makes no progress (nothing copied, nothing deleted); previously an unplaceable under-replicated volume made the loop spin forever, re-collecting the topology every 15 seconds. And propagate ewg.Wait() errors instead of swallowing them.

Chris LuandGitHub 68a4e3347f S3: track manifest blob ownership through multipart completion (#10386)
* s3: track manifest blob ownership through multipart completion

Manifest blobs made three orphan paths. A partial fold that failed midway
kept its earlier batches on volume servers while the write fell back to
flat chunks; the fold now records each saved blob and deletes them on
error. A completion that failed after preparing left its fresh manifests
behind on every retry; the completion state now owns them and deletes
them unless a failed rollback left the version entry still holding them.
And a completed upload removes its parts metadata-only, which stranded
the part-manifest blobs superseded by flattening; those are collected
during flattening and deleted once the completion commits.

Two shared-chunk hazards nearby: the version-file rollback deleted its
data, destroying the still-registered parts (worse once manifests
resolve to inner chunks), and the idempotent-replay cleanup data-deleted
leftover parts whose chunks the live object references. Both are
metadata-only now.

* s3: trim chunk manifest comments

* s3: test manifest fold rollback and part range selection

The fold-with-rollback and the boundary-to-byte-range logic were only
exercised by hand against a live server; give both an injectable seam
and cover the fold, the below-threshold and SSE no-ops, the midway
failure deleting the blobs it saved, and offset-vs-legacy-index range
selection including indexes that no longer address the chunk list.

Chris LuandGitHub cdb60069a6 filer: conditional UpdateEntry with a chunk-set write condition (#10382)
* filer: accept a WriteCondition on UpdateEntry, under the per-path lock

UpdateEntry was a bare read-modify-write: the precondition check, the
chunk garbage diff, and the store write could interleave with a
concurrent update to the same path. Take the per-path lock CreateEntry
already holds, and evaluate an optional CreateEntry-style WriteCondition
under it, failing with FailedPrecondition like expected_extended.

* filer: IF_CHUNKS_EQUAL write condition compares the stored chunk fid set

A chunk-preserving read-modify-write (tagging, setattr, copy-in-place)
races UpdateEntry's garbage diff: if a concurrent update empties the
chunk list first, the stale writer's commit resurrects fids that are
already queued for deletion, stranding the entry on a dead needle once
vacuum reclaims it. The reverse also holds: a writer that read an empty
chunk list can wipe chunks a concurrent update just added.

IF_CHUNKS_EQUAL guards both: the stored chunk fid multiset must still
equal what the caller read, order-independent, with an empty fids list
expecting no chunks. Absent entry counts as no chunks for CreateEntry
overwrites and transactions.

* filer: delete and append serialize on the entry path lock

DeleteEntry queues the entry's chunks for deletion and AppendToEntry
rewrites the chunk list, but neither held the per-path lock, so either
could interleave with a conditional update between its precondition
check and its write — a passed IF_CHUNKS_EQUAL would then resurrect
fids already on the deletion queue, or clobber a freshly appended
chunk. AppendToEntry keeps the cluster lock for cross-filer append
serialization; the path lock covers the local read-modify-write.

* filer: reuse lockPath in UpdateEntry lookup

Chris LuandGitHub 542495f1f1 S3: fold large chunk lists into manifest chunks on the direct write path (#10383)
s3: fold large chunk lists into manifest chunks on the direct write path

The S3 gateway uploads chunks itself and hands the filer a fully prepared
entry. On the routed write path (ObjectTransaction) the filer stores that
entry as-is, so a large PutObject or CompleteMultipartUpload persisted its
whole flat chunk list - a 900GB object carries 120k chunk references in one
entry. Manifestize on the gateway before the entry is written, the same way
mount, WebDAV, and filer.copy prepare theirs.

Multipart part boundaries also record byte offsets now: the stored chunk
indexes stop matching the entry once the list is folded, and partNumber
reads plus GetObjectAttributes prefer the offsets. Legacy index-only
records still work, with bounds checks instead of a possible panic.

Copy paths resolve a manifested source into data chunks before their
per-chunk copy loops - copying a manifest chunk raw would store its blob
as object data still pointing at the source - and a large copied list is
folded again on the destination. Completion likewise resolves manifest
chunks a part entry may carry (the filer folds an oversized UploadPartCopy
range) before rebasing part offsets.

Chris LuandGitHub 07c9e0db85 iceberg maintenance: write absolute s3:// locations into table metadata (#10363)
The maintenance operations built manifest, manifest-list, data-file and
metadata-log paths with a bare path.Join("metadata", ...), so a single
maintenance run wrote scheme-less relative paths into the new snapshot,
the metadata-log and the table xattr. SeaweedFS reads those back fine
because normalizeIcebergPath accepts both forms, but strict readers
resolve every location through S3FileIO and fail with "Invalid S3 URI,
cannot determine scheme", leaving the whole table unreadable after any
maintenance commit.

Add absoluteIcebergPath, the inverse of normalizeIcebergPath, and apply
it at every site that authors locations: rewrite_manifests, compact,
rewrite_position_delete_files, and the shared commit path. The base is
derived from the bucket and table path since that is where the worker
physically writes, matching the locations the REST catalog generates.

Chris LuandGitHub 564803becd shell: show who holds the cluster lock (#10353)
* regenerate master_grpc.pb.go with protoc-gen-go-grpc v1.6.2

The other generated pb files are already on v1.6.2; this one was stale.

* shell: keep unlock from racing the lease renewal

A renewal RPC in flight while ReleaseLock runs re-creates the lock on the
master after the release deletes it, and can blank the client name if the
renewal reads it mid-release. The stale-token release is then ignored, so
the lock stays held (sometimes anonymously) until it expires. Serialize
the renew and release RPCs, and set the client name before flipping
isLocked so the renewal never sends a partial acquisition.

* shell: restart lease renewal after a failed renewal

The renewal goroutine exits on error but never cleared its running flag,
so later locks in the same process were never renewed and silently
expired after ten seconds.

* shell: show who holds the cluster lock

A blocked lock command gave no hint that another client holds the lock
(the refusals only surfaced at -v=2), and cluster.status reported the
shell's own lock state as if it were the cluster's. Add a
GetAdminLockStatus RPC to the master so lock prints the holder before
blocking and cluster.status shows the actual cluster-wide holder. Both
degrade silently against masters without the RPC.

* shell: bound admin lock RPC attempts with timeouts

The lease, renew, release, and holder-status calls all ran without a
deadline, so an unresponsive master could hang the renewal goroutine,
an unlock (which now waits on the renewal mutex), or the shell prompt.
Give each attempt its own short context; the retry loops still resolve
a fresh leader on the next try.

* master: reject admin token release on non-leaders

A follower holds no lock state, so it answered a release with success
while the leader kept the lock until expiry. Refuse like LeaseAdminToken
does so the client can try the leader instead.

* shell: leave the lock release call unbounded

A release cut short by a deadline leaves the lock held on the master
until it expires, so a slow master would turn every unlock into a
ten-second ghost lock. Restore the single fire-and-forget attempt;
the timeouts stay on the lease and renew paths, where a stalled call
forfeits the lease anyway.

* shell: release only the token unlock started with

A RequestLock racing a slow release (the admin presence lock does this
on shutdown) could have its freshly acquired token sent in the release
request or zeroed by the trailing stores. Capture the token once under
the mutex and compare on clear so a concurrent acquisition survives an
in-flight unlock.

SeaweedFS_remote_cache_read_total{source,bucket,result} on the filer HTTP
path and the S3 gateway, so cache effectiveness of mounted buckets can be
graphed. Inline-content entries count as hits since they are served
locally without chunks. The filer purges the per-bucket series when the
bucket directory is deleted, so a standalone filer does not accumulate
series across bucket delete/recreate churn.

Chris LuandGitHub 1fda7aa7f1 master: assign re-picks once after its growth concludes instead of shedding (#10348)
The initiator's shed check (initiatedGrow != HasGrowRequest) compares
against an err from a PickForWrite that may predate the growth
concluding: the grower registers its volumes before clearing the flag,
so when growth lands between the failed pick and the check, the assign
shed ResourceExhausted even though a writable volume was already
registered. Re-pick once after observing the conclusion and shed only
if the volume layout still has nothing writable. Applies to both the
gRPC Assign and the HTTP dirAssign paths, which share the shed logic.

deterministically by widening the enqueue-to-check window.

Chris LuandGitHub 5553e7b876 mount: surface ENOSPC instead of endless waiting when the cluster is full (#10341)
When every volume is full, a chunk upload fails only after the assign
retry budget, the failed chunk's data is dropped, and the mount kept
accepting writes anyway. cp would crawl for hours pushing the rest of
the file through a pipeline that could not persist it, and only close()
reported an error - a generic EIO.

Poison the file handle on the first failed chunk upload so subsequent
writes fail immediately, and map "no writable volumes" / "no free
volumes" upload errors to ENOSPC so the writing process aborts with
"No space left on device". Also guard lastErr with a mutex: it was
written concurrently by uploader goroutines, and keep the first error
so later failures do not mask the root cause.

Chris LuandGitHub 25ab4c3cac preserve Content-Encoding for remote-mounted objects (#10340)
* remote storage: carry Content-Encoding into mounted entries

A RemoteEntry now records the remote object's Content-Encoding, and every
path that materializes a local entry from remote metadata (lazy fetch, lazy
listing, remote.mount, remote.meta.sync, remote.cache) stamps it into the
entry extended attributes, so HTTP and S3 HeadObject/GetObject return the
header. GCS and Azure populate it on listing and stat; S3 only exposes it
via HeadObject, so listings leave it empty.

* remote storage: set Content-Encoding when uploading to the remote

An entry carrying Content-Encoding in its extended attributes (a native S3
upload, or a value pulled from the remote) now keeps it when
filer.remote.sync or remote.copy.local writes the object to GCS, S3, or
Azure, instead of silently dropping it.

* gcs: read remote objects without decompressive transcoding

GCS transparently decompresses gzip-encoded objects on download, which
ignores range requests and returns byte counts that disagree with the
tracked RemoteSize. Request the stored bytes instead; chunked reads of
gzip-encoded objects then behave like any other object.

* remote storage: track Content-Encoding presence so removals propagate

A listing that does not report encodings (S3) leaves the field unset and
the local header untouched, while an authoritative report of no encoding
(GCS, Azure, any stat) now clears a previously stamped header instead of
leaving it stale. remote.cache also schedules a metadata update when only
the reported encoding changes.

* remote storage: propagate Content-Encoding on metadata-only updates

filer.remote.sync routes same-content changes through UpdateFileMetadata,
which only touched custom metadata (GCS, Azure) or tags (S3), so a
Content-Encoding change in the extended attributes never reached the
remote object's real header. GCS now patches contentEncoding alongside
the metadata, and Azure reissues the blob's HTTP headers with the new
value, carrying the others over since the call replaces the full set.
S3 stays tags-only: changing the header there means rewriting the
object, which the sync already does whenever content changes.

* remote.meta.sync: optional per-file stat for listing-omitted metadata

S3 listings carry no Content-Encoding, so entries synced from them never
learn it and the lazy-stat path never runs once an entry exists. With
-statFiles, each new or changed file whose listing left the encoding
unreported is stat-ed before reconciling, and the stat-derived value is
persisted so the next run only stats files that changed. Off by default:
it costs one remote request per file, and GCS and Azure listings already
carry the encoding.

* s3: apply metadata-only Content-Encoding changes with an in-place copy

Content-Encoding is S3 system metadata, so the tags-only metadata update
silently left the object's real header untouched. When the encoding
differs, reissue the object as a self-copy with replaced metadata,
carrying the content type and configured storage class like a fresh
write does. CopyObject caps at 5 GiB; beyond that the change is logged
and applies on the next content write.

* azure: skip the metadata call when user metadata is unchanged

An encoding-only change reissues the blob's HTTP headers; sending the
unchanged user metadata alongside it wastes a round trip and bumps the
blob's ETag once more than needed.

* s3: carry existing object metadata through the encoding copy

The replace directive drops everything not resent, and a mounted entry
usually has no local mime or user metadata, so the in-place copy wiped
the object's Content-Type, Cache-Control, user metadata, encryption
settings, and storage class. Read them back with a HeadObject first and
carry them over, overriding only what SeaweedFS manages: the encoding,
a locally set mime, and the configured storage class. S3 reports
Expires as a string while the copy input wants a time, so it is parsed
and skipped when malformed.

Chris LuandGitHub c015cc3939 generate vtproto marshalers for filer_pb and use them on the metadata log path (#10337)
* generate vtproto marshalers for filer_pb and use them on the metadata log path

Reflection-based proto.Unmarshal allocates a fresh message tree through
reflect.New on every call. On the metadata subscription fan-out the same
event is decoded once per subscriber, so reflect.New tops the decode
churn under many mounts.

Generate MarshalVT/UnmarshalVT/SizeVT for filer.proto (a separate
filer_vtproto.pb.go, filer.pb.go untouched) and call them on the log
entry marshal and the subscribe/replay decode paths. UnmarshalVT
allocates message structs directly and copies byte and string fields, so
it stays wire-compatible with proto.Unmarshal and preserves the
non-aliasing the persisted-log cache depends on.

For SubscribeMetadataResponse this cuts decode allocations 69 -> 50 and
~4.5us -> ~2.1us per event; the win scales with subscriber overlap.

* marshal log entries directly into the buffer

SizeVT is allocation-free and MarshalToSizedBufferVT writes into a
pre-sized slice, so the log entry can be marshaled straight into
logBuffer.buf. This drops the per-entry MarshalVT allocation and the
follow-up copy on the write path.

* expand vtproto benchmarks: marshal, decode, and marshal-into-buffer by chunk count

Parametrize by nested-message count (chunks per event) and add encode +
zero-alloc marshal-into-buffer benchmarks alongside the decode one, so
the write-path win from MarshalToSizedBufferVT is measurable too.

* keep proto.Unmarshal for metadata events to preserve UTF-8 validation

UnmarshalVT skips proto3's UTF-8 validation of string fields, so a
SubscribeMetadataResponse with an invalid-UTF-8 string (e.g. Directory
"\xff") that proto.Unmarshal rejects would decode and reach path
filtering and subscribers. Decode events with proto.Unmarshal again;
UnmarshalVT stays on the log entry paths, whose only variable-length
fields are bytes and so carry no UTF-8 constraint.

Tests cover the codec difference and that a malformed event is skipped
before delivery.

Chris LuandGitHub 8f29d0a91e route log buffer flush copies through the shared slab pool (#10336)
* route log buffer flush copies through the shared slab pool

Each flush copied the sealed window into a bytes.Buffer drawn from a
package-local sync.Pool. GC drains that pool, so once collections run
often (e.g. under GOMEMLIMIT) most flushes miss and Write grows a fresh
window-sized array, the dominant bytes.growSlice source under write load.

Copy into a size-classed slab from weed/util/mem instead. Slabs are
reused process-wide and returned to their exact size class after the
flush, so variable-sized flushes across many partitions stop churning
mismatched buffers.

* guard nil slab in flush releaseMemory

mem.Free(nil) resolves to the smallest slot pool and stores a zero-cap
slice, so a later mem.Allocate could return nil and panic. The current
call sites never pass nil, but the guard keeps a double release harmless.

Chris LuandGitHub 19dc085e33 master: statistics used size covers all collections and layouts (#10319)
StatFs on a mount reported cluster-wide total capacity but used size from
a single volume layout keyed by collection, replication, ttl, and disk
type. A mount without -collection therefore showed only the default
collection's usage, hiding data in named collections, and even a
collection-scoped mount missed volumes with a different replication,
ttl, or disk type.

Aggregate used size and file count across all layouts of the requested
collection, and across every collection when the collection is empty,

Chris LuandGitHub 013281b498 shell: volume.check.disk -resurrectMissingNeedles for never-vacuumed replicas (#10316)
An absent needle is normally indistinguishable from a vacuumed delete,
so check.disk skips it and replicas diverged by replication failures
cannot be reunited. But a replica with compaction revision 0 has never
been vacuumed: every delete it processed still holds its tombstone, so
a needle absent there is provably a missing write.

The new flag resurrects absent needles in exactly that case. The
receiving replica's live compaction revision is read after the index
snapshot and must be 0; vacuumed replicas keep the skip, now with the
revision in the message. The decision is passed per direction since
pass 2 runs pairs concurrently. Resurrected needles count toward
-nonRepairThreshold as before.

Chris LuandGitHub fa549e9c83 filer: harden TUS session authorization against cross-prefix access (#10315)
* filer: authorize TUS existing-session verbs against the validated stored target

Scope-check on TUS HEAD/PATCH/DELETE only populated a resource path for POST,
so a prefix-restricted token that learned another tenant's session id could act
on that session and land content at a TargetPath its own AllowedPrefixes forbid.

Split the filer JWT check into authenticateFilerJwt (signature and method) and
authorizeFilerJwtPaths (resource scope), and make the scope check fail closed:
a prefix-restricted token with no resolved resource path is denied instead of
authorized on signature alone. The TUS handler now authenticates first, reads
and validates the session once, authorizes the stored TargetPath, then operates
on that single pinned snapshot. readTusSessionInfo rejects a session whose id,
target or size is unusable, and getTusSession is split so the authorization
lookup no longer lists chunks.

* filer: reject non-canonical TUS upload ids

The uploads route took the first path component as the session id, so a trailing
path or other non-canonical spelling aliased one session under several URLs.
Require the id to be a canonical UUID, the only form the server mints, both at
routing and when reading a session's metadata, so one URL maps to one resource.

* filer: revalidate the pinned TUS session before completing an upload

Completion re-read chunks but not the session identity, so a PATCH finishing
after a concurrent DELETE or metadata replacement could still land at the id's
stored path. Before completing, confirm the session still exists and its target,
size and creation time are unchanged from the authorized snapshot; otherwise the
completion fails instead of writing to a path the request never authorized.

* filer: log TUS session lookup failures before returning not-found

readTusSessionInfo and loadTusSessionChunks failures answered "not found" with
no log line, so a transient filer or listing error was indistinguishable from a
genuinely missing session. Log the lookup at V(1) (a missing session is common
and benign) and the chunk-load error at Errorf (the session already resolved).

Chris LuandGitHub c1a1e3c1e3 shell: volume.tier.upload keeps volume replicas (#10314)
* volume: copying a remote-backed volume only needs space for the index

VolumeCopy sized its target-location check by the source .dat even when
that .dat lives in a cloud tier and only .idx/.vif land locally, so
re-replicating a tiered volume demanded the full remote size in free
disk. Require the index size instead.

* shell: volume.tier.upload keeps volume replicas

Tiering a replicated volume deleted every replica but the upload
source, leaving one server holding the only .idx and the only .vif
that knows the remote object key — losing that server orphaned the
volume even though its data sat intact in the cloud.

Replicate the uploaded .idx/.vif onto the other replica servers
instead (VolumeCopy skips the .dat for remote-backed volumes), so all
replicas serve reads from the same remote object and the volume keeps
its replica count. An already-tiered replica is preferred as the
upload source, so a rerun after a partial failure reuses the existing
remote object instead of uploading a second copy under a new key.

* shell: group tier upload locations instead of re-prepending

* rust volume: copying a remote-backed volume only needs space for the index

Mirror the Go VolumeCopy change: size the free-location check by the
source .idx when the .dat lives in a cloud tier, since only .idx/.vif
land locally.

Permission checks compared paths with raw string prefixes, so a

/tenants/alice-archive, letting a scoped user read and overwrite

same flaw. Route both through pathWithin, which cleans the paths and
requires exact equality or a separator-delimited descendant.

Chris LuandGitHub e7be6bb2f8 filer: allow clearing a bucket read-only flag stuck after quota removal (#10310)
* filer: allow clearing a bucket read-only flag stuck after quota removal

Once s3.bucket.quota.enforce marks a bucket read-only, removing or
disabling the quota orphans the flag: enforcement skips buckets with a
non-positive quota, and fs.configure merges booleans with OR so
-readOnly=false could never turn it off. The only way out was deleting
the whole path rule.

- s3.bucket.quota -op=remove/disable and the admin server quota update
  now lift the read-only flag on the bucket's path rule
- fs.configure now honors explicitly passed false boolean flags
  (-readOnly, -fsync, -worm) instead of OR-merging them away

c006dc563e ec: remove .ecsum sidecars on destroy / shard delete; align Go and Rust cleanup (#10307)
* fix(rust-volume): remove .ecsum sidecars on EC destroy / shard delete

Rust EcVolume::destroy removed shards and .ecx/.ecj/.vif but left bitrot
checksum sidecars (.ecsum / .ecsum.v*). On clusters that run weed-volume
(not Go weed volume), collection.delete therefore orphans every sidecar
while correctly wiping shards — observed live on 4.39 (14/14 .ecsum
survived after collection.delete on a freshly encoded EC volume).

Go Destroy already calls RemoveBitrotSidecars; this brings Rust to parity:
- hoist remove_bitrot_sidecars into ec_bitrot (shared helper)
- call it from EcVolume::destroy for dir / dir_idx / ecx_actual_dir
- call it from Store::delete_ec_shards when a disk has no remaining shards
- unit test: test_destroy_removes_bitrot_sidecar

* rust volume: gate the shard-delete sidecar sweep on a local shard removal

Only sweep a disk's .ecsum when this delete actually removed a shard file
there, matching Go's found gate: a delete that never touched a disk must not
strip a sidecar it does not own — a shared -dir.idx sibling with surviving
shards, or an ec.rebuild index-prep copy that lands .ecx/.ecsum before any
shard. The shard-presence probe now treats unexpected stat errors as
"exists" so a transient failure cannot orphan-classify live shards, and
check_all_ec_shards_deleted reuses it.

* rust volume: destroy() sidecar sweep needs only the data and idx bases

ecx_actual_dir is always one of the two, so the third branch could never
run; this is now exactly Go Destroy()'s two-base sweep.

* rust volume: call the shared sidecar removal helper directly

* rust volume: unit-test remove_bitrot_sidecars

Mirrors Go's TestRemoveBitrotSidecars: legacy and versioned sidecars are
removed, a shard file and a longer-vid sidecar survive, absent is success.

* rust volume: keep the shared idx-base sidecar while a sibling disk has shards

One -dir.idx serves every location, so emptying one disk must not sweep
<idx>/<vol>.ecsum out from under a sibling that still holds shards. Nothing
reads the idx-base sidecar today, but .ecx shows index-dir files are real;
this keeps the defensive sweep safe if a writer ever lands one there.

* ec shard delete: keep the shared idx-base sidecar while a sibling disk has shards

One -dir.idx serves every disk, so emptying one disk must not sweep
<idx>/<vol>.ecsum out from under a sibling that still holds shards of the
volume — the same gate the Rust volume server applies. A status error counts
as in-use so a transient failure never strips it early.

* rust volume: drop a shard-only disk's stale .vif with the node's last shard

Go's removeEcSharedIndexFiles also clears the data-base .vif in the
all-shards-gone pass, gated on .idx absence so a disk still hosting the
source volume keeps its live .vif; the Rust delete path left it behind.
Unexpected stat errors count as .idx-present so a transient failure never
strips a live volume's .vif.

Chris LuandGitHub ce82e3a057 filer: scope TUS HEAD/PATCH/DELETE against the session target path (#10309)
* filer: scope TUS HEAD/PATCH/DELETE against the session target path

checkTusJwtAuthorization only populated the scoped-path list for POST, so
a prefix-restricted token was scope-checked at session creation but not on
HEAD/PATCH/DELETE, which act on an existing session addressed by id. A
low-privilege tenant holding a valid write token who learns another
upload's session id could PATCH attacker bytes into that session, or
DELETE/HEAD it, landing content at a target path its own AllowedPrefixes
forbids. The session id is unguessable to an unauthenticated attacker but
is not an authorization boundary against a legitimate tenant.

Resolve the effective target for HEAD/PATCH/DELETE from the session's
stored TargetPath and scope the prefix check against it, the same way POST
scopes the create target. The scoped paths are resolved lazily so the
session read runs only for a prefix-restricted token; unrestricted tokens
and deployments without a signing key touch no extra state. An unknown
session stays unscoped so the handler still answers 404.

* filer: fail closed when a TUS session target cannot be resolved

The lazy scope resolver swallowed every readTusSessionInfo error and left
the request unscoped, so a filer read error or a corrupt session .info
would authorize a prefix-restricted token against a target the server
never resolved. Only a genuinely missing session should stay unscoped (so
the handler answers 404); any other failure now propagates and denies the
request. checkJwtAuthorizationScoped's resolver returns an error and a
failed resolution is treated as not-authorized.

* filer: fold the scoped-path resolver into checkJwtAuthorization

checkJwtAuthorization now takes the lazy resolver directly instead of a
separate checkJwtAuthorizationScoped wrapper, and the surrounding comments
are trimmed to the load-bearing why.

Chris LuandGitHub 298ab35fd7 shell: default batch size for ec.encode and ec.decode (#10308)
* shell: ec.encode batches 10 volumes by default

Encoding a whole collection as one batch means a late failure leaves
everything half-converted. Default -batchSize to 10 so each batch is
encoded, rebalanced, verified, and its originals deleted before the
next starts. -batchSize=0 keeps the all-at-once behavior. Batch
progress messages now print only when there is more than one batch,
so small runs read as before.

* shell: ec.decode decodes in batches, refreshing topology in between

ec.decode walked every volume off the single topology snapshot taken
at startup, which goes stale as earlier decodes move shards around and
create volumes. Decode 10 volumes per batch by default, re-collecting
the topology and rebuilding the free-space accounting between batches.
-batchSize=0 keeps the single-snapshot behavior.

Chris LuandGitHub 5c511c4894 ec.encode: don't rebalance against a topology that predates the new shards (#10303)
Mounting freshly generated shards notifies the master asynchronously, while the post-encode rebalance plans from a fresh VolumeList snapshot; a snapshot that predates the delta shows zero shards, so the balance plans no moves and silently succeeds, and the original .dat is deleted with all shards on the generation host. Poll until every encoded volume reports a full shard set before balancing — across all disk types, since fresh shards register under the source volume's disk type, and scoped to the newest encode generation so an orphaned older generation neither satisfies the wait nor defeats the clump check. As defense in depth, refuse to delete originals when a volume's shards still sit on one node while another node has free EC slots.

presigned PUT that signs content-type carries
X-Amz-SignedHeaders=content-type%3Bhost; when a client or proxy decodes
the %3B, the parameter vanished and the upload failed with
MissingFields, while AWS accepts the raw ';' as query data. Re-encode
it before routing so the pair survives parsing and signature
verification.

c17aebeecf fix(filer.backup): prevent silent backup data loss on transient not-found (#10295)
* fix(filer.backup): stop silently dropping events on transient not-found

Under a write burst, filer.backup could consume a metadata event (advancing
the persisted offset) without replicating the file, with no error logged:

1. filersink CreateEntry/UpdateEntry swallowed replicateChunks errors
   (glog.Warningf + return nil), so the offset advanced past entries that
   were never written.
2. The manifest-chunk branch of replicateChunks resolved via LookupFileId
   with no retry, unlike the data-chunk branch — transient lookup races
   dropped exactly the large manifest-backed files while small
   inline-content siblings landed.
3. isIgnorable404 matched "LookupFileId" / "volume id ... not found",
   misclassifying those races as genuine source 404s at the backup layer.

Fix: on a replicateChunks failure the filer sink now skips only when the
live source has moved past the replayed version (deleted or strictly-newer
mtime) — lossless, a later event carries the current content — and
propagates otherwise so the event is retried. The manifest resolve retries
transient errors like the data-chunk path. isIgnorable404 is narrowed to
genuine 404s; non-filer sinks and the initial-snapshot walk, which relied
on the broad match as their only lossless-skip valve, now make the same
live-source decision (filersink.SourceSupersedes) instead of retrying
forever on a permanently gone volume.

Tests cover propagation of unconfirmed lookup failures, the narrowed 404
classification, and the supersession guards.

* fix(filer.backup): derive supersession path with directory fallback

eventSourceSuperseded built the source path from NewParentPath alone.
Legacy metadata events (persisted by older filers) carry an empty
NewParentPath, so the probe looked up "/<name>", read the miss as
"source gone", and skipped a live file on a transient lookup error —
the silent drop this change is meant to eliminate.

Derive the path via MetadataEventTargetFullPath (the same directory
fallback genProcessFunction uses) and cover both event shapes with
TestEventSupersessionProbe_PathDerivation.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(filersink): retry manifest resolve only for transient errors, bounded when unverifiable

The manifest-resolve retry stopped only when hasSourceNewerVersion proved
the source moved past the replayed version, which wedged the sink in two
cases: incremental sinks use dated target keys that cannot map back to a
source path (supersession never provable), and permanent resolve errors
(corrupt manifest data, bad file ids) fail forever while the source entry
stays live.

Gate the retry instead: keep retrying only transient errors (volume-lookup
races, network interruptions), stop after a few attempts when supersession
cannot be checked, and propagate everything else immediately so the
configured metadata error policy applies (-disableErrorRetry included).
Propagation is lossless: filer.backup's fallback decides with the event's
real source key, and both filer.backup and filer.sync re-deliver the event
(RetryForeverOnError) without advancing the offset.

* fix(filer.backup): make error classifiers nil-safe

isIgnorable404, isSourceLookupError, and isTransientResolveError called
err.Error() without a nil guard. All current call sites pass a non-nil
error, but the guard is free and matches isRetryableNetworkError.

Chris LuandGitHub 9a7cfaf371 admin: stop holding the shell admin lock across whole scheduler batches (#10290)
* admin: let waiting shell clients win the admin lock

The admin lock manager re-acquired the cluster shell lock immediately
after releasing it, while a waiting weed shell client only polls the
master once a second, so an operator could lose the race indefinitely.
Leave the lock free for slightly more than one poll interval before
re-acquiring, and once overlapping reference-counted holds have kept
the lock continuously held for over a minute, make new admin-side
acquires wait for a full release before piggybacking.

* admin/plugin: take the shell lock per detection and per job, not per batch

The default-lane scheduler acquired the cluster shell lock once and
held it across the whole pass: every due job type's detection plus all
of its dispatched jobs, each drained to completion. A manual weed
shell operation sharing that lock could stall behind the batch for up
to the extended execution window.

Hold the lock only while it protects something: around each detection
scan and around each dispatched job. Manual shell operations now wait
for at most one in-flight job. The admin UI detect+execute path stops
wrapping dispatch in an outer hold, since a nested acquire would
deadlock against the lock manager's fairness window; detection and
per-job dispatch take the lock themselves.

* admin/plugin: stop extending the dispatch window to the largest job estimate

When any proposal's estimated runtime exceeded the remaining
JobTypeMaxRuntime, the whole dispatch context was replaced with a
fresh one capped at eight hours, so a single balance backlog could
hold the default lane (and with it erasure_coding and vacuum
detection) for that long.

Keep the dispatch window at JobTypeMaxRuntime and instead detach each
started attempt onto its own estimated-runtime deadline. Large jobs
still get their full time once started; jobs not yet started when the
window closes are canceled and re-proposed by a later detection, so
sibling job types get a turn every window.

* worker/balance: re-check each planned move against the master before executing

A balance plan is computed at detection time, but the admin lock is
released between detection and execution, so a manual shell operation
can rearrange the volume in the gap. The task's own guards catch a
vanished source, but a target that gained a replica in the meantime
would be silently overwritten by VolumeCopy and the source delete
would then reduce the volume to a single copy.

Before executing each move, ask the master for the volume's current
locations (uncached) and skip the move if the volume has left the
source or the target already holds a replica. Skipped moves fail with
a stale-move error and the next detection replans them. Without master
addresses in the cluster context the check is skipped, preserving the
old behavior with older admins.

* admin: block re-acquire while the final lock release is in flight

Release dropped the manager mutex before calling ReleaseLock, so a
concurrent Acquire could see hold count zero and call RequestLock
while the locker still considered itself locked. That request no-ops,
leaving a hold with no live master lease. Track the in-flight release
and make Acquire wait for it.

Also normalize a nil release function from lock manager
implementations, and make the yield and fairness windows per-instance
fields so tests stop mutating globals.
