Yaroslav HalchenkoandClaude Code 2.1.217 / Claude Opus 4.7 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.

* [DATALAD RUNCMD] Fix non-ambiguous typos with codespell -w

Auto-applied fixes to the 44 remaining single-suggestion typos across

^^^ Do not change lines above ^^^

* Revert breaking codespell fixes; whitelist unknwon and atleast

Two of the auto-applied `codespell -w` fixes were false positives that
would break the build/tests:

- go.mod: `github.com/unknwon/goconfig` is a real Go module path — the
  upstream author's GitHub handle is literally `unknwon`. Renaming to
  `unknown` would fail dependency resolution.
- test/benchmark/fuse_db/bin/{sqlite_verify.py,run_mysql.sh,run_sqlite.sh}:
  `atleast` is a literal CLI mode value (a string constant compared and
  passed as a positional argument). Rewriting to `at least` splits it
  into two arguments and breaks the mode check.

Reverted those files and whitelisted both words in .codespellrc so
future runs won't re-suggest the same broken fixes.

Chris Lu f724828bcb fix(ec): never delete recoverable EC shards on startup/reconcile (the non-empty-.dat sibling of the stub bug) (#9941)
* fix(ec): never delete recoverable shards on startup/reconcile (size-direction + byte-exact .dat)

EC startup validation and the cross-disk reconcile could delete the only
copy of distributed-EC shards whenever a non-empty .dat sat beside them.
This is the same data-loss class as the empty-.dat-stub fix, now for a
real (non-empty) stale or partial .dat.

validateEcVolume: the discriminating signal is the shard size relative to
the .dat's full encode, not the shard count.
  - shards smaller than expected: an interrupted local encode left partial
    shards and the .dat is the complete source -> reclaim the .dat.
  - shards equal to expected: a valid (or still-distributing) EC volume ->
    keep; the shards may be the only copy.
  - shards larger than expected: the .dat is the stale/partial side (e.g. an
    interrupted decode left a half-written .dat next to the real shards) ->
    keep.
Previously any size mismatch, a low shard count beside a .dat, or a
transient stat error returned "delete", wiping sole-copy shards. Now every
ambiguity (size mismatch in either direction, inconsistent shard sizes,
transient I/O error, partial shard set) keeps the data; only a credible
full source .dat with no partial set to lose is reclaimed.

handleFoundEcxFile: a shard load failure (corrupt/locked .ecx, EMFILE
during a mass restart, transient I/O) no longer deletes the EC files when a
.dat exists -- it only unloads and keeps the files for retry. All deletion
authority now flows through validateEcVolume.

pruneIncompleteEcWithSiblingDat: count shards NODE-WIDE (a set split across
sibling disks summing to >= dataShards is independently recoverable and is
left alone), and require the sibling .dat to byte-exactly match the size
.vif recorded at encode time before deleting -- the prior "at least this
big, or bigger than a superblock" gate could trust a stale .dat and wipe
sole-copy shards. EC encode records the source size in .vif, so this gate
works for real volumes; older volumes without it fail safe (kept).

Rust volume server mirrors all of the above: size-direction + keep-on-
ambiguity in validate_ec_volume, keep-on-load-failure in
handle_found_ecx_file, and the node-wide + byte-exact gate in the prune.
The Rust validate/prune paths now resolve the data-shard count from the
volume's own .vif instead of hardcoding 10+4, so custom-ratio volumes are
not mis-sized and wrongly deleted on reboot.

Existing tests that encoded the old (unsafe) "delete on low count / size
mismatch" behavior are updated to the safe expectation, and new regression
tests cover the partial-decode-.dat-keeps-shards and transient-error-keeps
cases (Go and Rust); they fail on the pre-fix code.

* fix(ec): record DatFileSize in planted EC .vif for the prune test; trim comments

The multi-disk lifecycle e2e test planted a partial EC leftover with an
empty .vif, so the byte-exact prune gate (which a real encoded volume
satisfies via its recorded source size) kept it instead of cleaning up.
Record DatFileSize + the EC ratio in the planted .vif, matching production.

Also condense the verbose comments added in this change to the repo's
concise style.

Chris Lu 1c9039d3ac fix(seaweed-volume): stop EC shard deletion from phantom .dat on restart (#9874)
* fix(seaweed-volume): stop EC shard deletion from phantom .dat on restart

On startup load_existing_volumes() scans .vif/.idx entries (not just
.dat). For distributed EC, a volume's .vif can be mirrored onto a disk
whose .ecx lives on a sibling disk, so the per-disk ecx check is false
and the loader falls through to Volume::new, which always creates the
.dat if missing -> a phantom 8-byte superblock stub. The store-level
prune_incomplete_ec_with_sibling_dat then treats that stub as the
authoritative source and deletes the real EC shards on sibling disks. Go
guards the same case (disk_location.go: 'Without this guard NewVolume
below would create a phantom empty .dat') but only same-disk.

Fix A (root cause): in load_existing_volumes, don't create a .dat during
load. Skip the entry when there is no local .dat AND the .vif does not
reference remote files -- remote-tiered volumes have no local .dat but
must still load via the remote path. Uses the robust check_dat_file_exists
helper so a transient stat error doesn't skip a real volume. New volumes
go through create_volume(). Covers the cross-disk .vif/.ecx split Go's
same-disk hasEcxFile() misses.

Fix B (defense in depth, Go + Rust): when the EC .vif records no source
size (dat_file_size==0), require the sibling .dat to be strictly larger
than a bare superblock, so an empty 8-byte stub can't pass the
credibility gate. Previously it fell back to SUPER_BLOCK_SIZE, which an
8-byte stub exactly meets.

Adds regression tests reproducing the cross-disk lone-.vif phantom and
the 8-byte stub gate; updates an existing prune test to use a real
collection so its .ecx lookup matches the loaders.

* fix(storage): don't create phantom .dat from lone .vif on Go volume load

Mirror Fix A on the Go side. loadExistingVolume scans .vif/.idx entries,
and for distributed EC a .vif can be mirrored onto a disk whose .ecx is
on a sibling disk. The same-disk hasEcxFile() guard does not fire there,
so the loader falls through to NewVolume(createDatIfMissing=true) and
writes an 8-byte phantom .dat, which the sibling-.dat prune then uses to
delete the real EC shards on sibling disks. Skip the entry when there is
no local .dat AND the .vif has no remote file (via MaybeLoadVolumeInfo);
remote-tiered volumes have no local .dat but must still load.

Adds TestLoneVifDoesNotCreatePhantomDat (fails without the guard) and
TestRemoteTier_DiskScanLoadsRemoteOnlyVolume (fails if the guard skips a
remote-only volume).

Chris Lu f410d975c7 fix(ec): resolve EC data-shard count from the volume's .vif on reboot (#9779)
* fix(ec): resolve EC data-shard count from the volume's .vif on reboot

A volume server never loads a cluster EC config into memory, so startup
decisions that assumed 10 data shards mishandled volumes whose .vif
records a different ratio:

- validateEcVolume sized the expected shard against 10 data shards and
  required >=10 local shards, so a volume with a non-default ratio and a
  coexisting .dat could be wiped on reboot. Read the ratio from the .vif.
- pruneIncompleteEcWithSiblingDat used the hardcoded 10-shard threshold,
  so a full data set for a non-default ratio with a healthy sibling .dat
  was wiped as a partial leftover. Use the EcVolume's .vif-derived ratio.

Behavior is unchanged for the standard 10+4 layout (the .vif resolves to
10). Adds storage-level reboot tests.

* ec: avoid per-call allocations in ecDataShardsFromVif

Address review: the helper runs once per EC volume at startup. Replace the
slice+map dedup of the two dirs with direct conditional checks via a small
ecDataShardsFromVifDir helper, eliminating the heap allocations and GC
pressure when loading many volumes.

Chris Lu af8d4e00ee fix(ec_mount): reject 0-byte .ecx and aggregate cross-disk failures (#9542)
* fix(ec_mount): reject 0-byte .ecx and aggregate cross-disk failures

MountEcShards's per-disk loop bailed on the first disk returning a
non-ENOENT error, and NewEcVolume wrapped its ENOENT with %v so the
caller's `err == os.ErrNotExist` check never matched. On a multi-disk
volume server where ec.balance / ec.rebuild had distributed shards
across sibling disks while the matching .ecx never arrived, the mount
loop bailed after disk 0 with "cannot open ec volume index" and the
operator never saw that the rest of the disks were also empty. The
companion failure mode is a 0-byte .ecx stub left by EC distribute's
writeToFile after a mid-stream copy failure: Stat() succeeds, treating
the stub as a valid index, and downstream mount work proceeds against
an empty file.

Wrap the ec-volume open errors with %w, treat a 0-byte .ecx as
os.ErrNotExist (in NewEcVolume, findEcxIdxDirForVolume, and
HasEcxFileOnDisk), and have MountEcShards collect per-disk failures
before returning a single aggregated error. The "no .ecx anywhere"
case gets a distinct error so the orchestrator can re-copy the index
from a healthy replica rather than retry against the same broken
state.

* fix(ec_reconcile): indexEcxOwners also rejects 0-byte .ecx stubs

findEcxIdxDirForVolume already skipped 0-byte .ecx during MountEcShards,
but indexEcxOwners (used by reconcileEcShardsAcrossDisks at startup)
still recorded the first .ecx by name only. On a store where one disk
holds a 0-byte stub left by a failed EC distribute and a sibling disk
holds the real index, the stub would win the owner selection — and
NewEcVolume's new size check would then refuse to load against it,
leaving the orphan shards unloaded even though a valid index exists.

Mirror the size check from findEcxIdxDirForVolume: skip directory
entries whose .ecx Info() reports size 0 or whose Info() call fails.

* fix(ec_mount): accept 0-byte .ecx as valid empty index

The previous commit treated a 0-byte .ecx in NewEcVolume as
os.ErrNotExist, on the assumption that any empty .ecx was a stub left
by a failed copy stream. That broke the legitimate empty-volume case:
when an EC volume's source .idx has no live entries (e.g. all needles
deleted before WriteSortedFileFromIdx), the sorted .ecx is genuinely
0 bytes and must mount. The integration test
TestEcShardsToVolumeMissingShardAndNoLiveEntries fails with
"MountEcShards: no .ecx index found on any local disk" because the
mount path now refuses the legitimate empty index.

A 0-byte .ecx left by a failed copy stream is indistinguishable from
the legitimate empty case by file size alone. Preventing stub files
from being written is the receiver-side cleanup in writeToFile's job
(the companion EC distribute PR), not NewEcVolume's at mount time.

The cross-disk lookup helpers (findEcxIdxDirForVolume, HasEcxFileOnDisk,
indexEcxOwners) keep their size > 0 preference: when a real .ecx
exists on a sibling disk alongside a stub, we still want to route
mounts and reconcile at the real one. If no non-zero .ecx exists
anywhere, the per-disk fallback in MountEcShards can still open the
0-byte .ecx and the volume mounts.

Replace TestMountEcShards_ZeroByteEcxOnlyDisk with
TestMountEcShards_EmptyEcxMountsSuccessfully, which pins the
empty-volume invariant.

Chris Lu c11ff6657b fix(ec): mirror EC sidecars onto every shard-bearing disk at startup (#9525)
* fix(ec): mirror EC sidecars onto every shard-bearing disk at startup

In a multi-disk volume server, ec.balance and ec.rebuild can land shards
on a disk that does not also hold the matching .ecx / .ecj / .vif index
files. The orphan-shard reconciler in reconcileEcShardsAcrossDisks
already loads those shards by pointing the EcVolume at the sibling
disk's index files; reads work, but any failure on the index-owning
disk silently disables every shard on the other disk, even though those
shards are physically fine.

This change adds mirrorEcMetadataToShardDisks, a startup pass that
physically replicates .ecx / .ecj / .vif onto each disk that holds
shards but is missing them. Each copy is atomic (tmp + fsync + rename)
and idempotent (a destination that already has the sidecar is
preserved). After mirroring, the cross-disk reconciler prefers the
local IdxDirectory so the EcVolume mounts self-contained; the
cross-disk virtual mount remains as a fallback for volumes whose mirror
failed (read-only target, out of space, partial copy on a previous
boot).

The same-disk invariant the EC lifecycle (encode / decode / balance /
vacuum / repair) was already documented as promising is now actually
restored at boot, so a future failure of one disk in a split-shards
layout no longer takes the other disk's shards with it.

Tests cover the orphan-layout mirror (dir0 receives the .ecx / .ecj /
.vif from dir1) and idempotency (an existing destination .ecx is not
overwritten with the owner's copy).

* fix(ec): handle legacy pre-dir.idx sidecar layout in mirror skip-check

hasAllEcSidecarsLocally checked only the modern destination path
(IdxDirectory for .ecx/.ecj, Directory for .vif). A destination disk
that still had a legacy .ecx in its data dir (written before -dir.idx
was set) would report "not present" and the mirror would write a
second copy to IdxDirectory, leaving two .ecx files on disk.

Matches HasEcxFileOnDisk's open-with-fallback contract: check the
modern path first, then the opposite directory. Factored the
exists-and-not-a-dir check into a small statRegular helper so the
fallback ladder stays readable.

* rust(seaweed-volume): mirror EC sidecars onto shard-bearing disks at startup

Port of the Go fix (commit 088e26ea6) to the Rust volume server.
Adds Store::mirror_ec_metadata_to_shard_disks, called from
add_location / load_new_volumes before the cross-disk orphan
reconciler. Physically copies .ecx / .ecj / .vif from the disk that
owns the index files onto every disk holding shards but missing
sidecars, so each shard-bearing disk ends up self-contained.

The reconciler now prefers the local idx_directory when the mirror
has installed a .ecx there; the cross-disk virtual mount remains as
the fallback for volumes whose mirror failed (read-only target, out
of space, partial copy on a previous boot). Adds ec_local_ecx_path
helper shared between reconcile and mirror to detect the post-mirror
fast path.

Mirrors the Go-side fallback in hasAllEcSidecarsLocally: when
-dir.idx is configured and the destination still has a legacy .ecx
in its data dir, that's recognized so the mirror does not write a
duplicate copy into idx_directory.

Tests cover the two key cases: orphan layout (dir0 receives the
sidecars from dir1) and idempotency (a pre-existing destination .ecx
is not overwritten).

* trim verbose comments on EC mirror code

Comments now lead with the WHY (non-obvious constraints, the
post-mirror fast path, why local copies are authoritative) and drop
restate-the-code blocks, headers, and section dividers. Behavior is
unchanged; all existing tests still pass on both the Go volume
server and the seaweed-volume Rust port.

* drop github issue refs from added comments

Two stray "#9212" references slipped into comments I added on the
cross-disk reconciler call site. The git log carries the issue
history; comments stand on their own.

* test(ec): accept rebuild on either disk after sidecar mirror

TestEcLifecycleAcrossMultipleDisks asserted the rebuilt shard 9 must
land at the disk-0 path. With the boot-time sidecar mirror, every
shard-bearing disk owns its own .ecx, so VolumeEcShardsRebuild now
picks whichever disk hosts the most shards — disk 1 in this layout
after the deletion. The shard can legitimately rebuild on either
disk; the test now accepts both and uses the chosen path for the
subsequent mount + read verification.

Chris Lu bf9110ebd3 fix(ec): mount falls back to sibling-disk .ecx (fixes #9519) (#9521)
* fix(ec): mount falls back to sibling-disk .ecx (fixes #9519)

MountEcShards iterated DiskLocations and on each disk called LoadEcShard
with that disk's IdxDirectory as the .ecx home. When ec.balance lands the
.ec?? shard on disk A but the .ecx on sibling disk B of the same volume
server, NewEcVolume ENOENTs the .ecx and returns "cannot open ec volume
index ...". That error is not os.ErrNotExist, so the per-disk continue
branch did not engage and the mount loop bailed before trying any other
disk.

The startup reconciliation in reconcileEcShardsAcrossDisks already
handles this layout for orphan shards discovered on boot (issue #9212).
This change mirrors the same primitive on the mount path: look up the
.ecx owner across all DiskLocations once and route NewEcVolume at that
directory whenever the disk being mounted does not own its own copy of
the .ecx. Same-disk mounts are unaffected because HasEcxFileOnDisk keeps
LocalIdxDirectory in play.

Adds a regression test that plants the index files on a sibling disk
AFTER NewStore returns (so the startup reconcile is a no-op for that
vid) and verifies MountEcShards succeeds; also pins the same-disk
baseline against accidental re-routing.

* fix(ec): skip redundant stats in cross-disk .ecx lookup (review)

Two follow-ups from gemini-code-assist on #9521:

1. MountEcShards: when findEcxIdxDirForVolume already returned a path
   that lives on this disk's IdxDirectory or Directory, the disk owns
   the .ecx — skip the HasEcxFileOnDisk stat and use the local idx dir
   directly. Only re-check when the disk's directories are neither, so
   the duplicate-.ecx-on-multiple-disks edge case is still honored.

2. findEcxIdxDirForVolume: hoist the seen map across the location loop
   so a shared IdxDirectory (one -dir.idx paired with several -dir
   entries) is only stat'd once per call.

Both are I/O optimizations; behavior is unchanged. Existing
cross-disk and same-disk regression tests still pass.

* docs(ec): drop issue/PR references from cross-disk mount comments

Comments and test docstrings stand on their own; the issue number
adds nothing a reader can act on and goes stale across forks. Keep
the description of *what* the layout is and *why* the fallback
exists, just without the reference.

Chris Lu de28c4df61 fix(storage): prune partial EC shards when sibling disk has healthy .dat (#9478) (#9480)
* fix(storage): prune partial EC shards when sibling disk has healthy .dat (#9478)

handleFoundEcxFile only checks for .dat in the same disk location as the
EC shards. In a multi-disk volume server an interrupted encode can leave
.ec?? + .ecx on disk B while the source .dat still lives on disk A: the
per-disk loader sees no .dat next to .ecx, mistakes the leftover for a
distributed-EC layout, and mounts the partial shards. The volume server
then heartbeats both a regular replica and an EC shard for the same vid
and the master keeps both.

Sweep the store after per-disk loading and before the cross-disk
reconcile to delete partial EC files when a healthy .dat for the same
(collection, vid) exists on a sibling disk. Push DeletedEcShardsChan for
every pruned shard so master forgets the new-shard message the per-disk
pass already emitted, instead of waiting for the next periodic heartbeat.

* fix(seaweed-volume): mirror prune of partial EC with sibling .dat (#9478)

Rust port of the same Store-level prune added to weed/storage. The
per-disk EC loader in disk_location.rs only checks for .dat in the same
disk as the EC shards, so an interrupted encode that leaves .ec?? + .ecx
on disk B while the source .dat sits on disk A is mounted as if it were
a distributed-EC layout. The volume server then heartbeats both a
regular replica and an EC shard for the same vid.

Sweep the store after per-disk loading and before the cross-disk
reconcile, dropping in-memory EcVolumes with fewer than DATA_SHARDS_COUNT
shards when a .dat for the same (collection, vid) exists on a sibling
disk, and remove all on-disk EC artefacts for them. The Rust heartbeat
path already diff-emits deletes from the next ec_volumes snapshot, so no
explicit delete-channel push is needed here.

Tests cover both the issue 9478 layout and a distributed-EC layout with
no .dat anywhere on the store, which must be left alone.

* fix(storage): validate sibling .dat size before deleting partial EC (#9478)

The earlier prune deleted partial EC files whenever any .dat for the
same vid existed on a sibling disk — including a zero-byte shell. A
shell is no more useful than the partial shard it would replace, and
the partial shard might still combine with shards on other servers
in a recoverable distributed-EC layout. Wiping it based on a corrupt
sibling .dat is data loss masquerading as cleanup.

Tighten the check: when the EC's .vif recorded a non-zero source size
in datFileSize, require the sibling .dat to be at least that many
bytes; otherwise fall back to "at least a superblock". The .vif value
is what the encoder wrote at the moment the source was sealed, so a
sibling .dat smaller than that is provably truncated. Carry the size
through indexDatOwners alongside the location.

The Rust port had the same gap and an additional bug behind it:
EcVolume::new wasn't reading datFileSize from .vif, so the safety
check always fell back to the superblock floor. Wire datFileSize
through. The existing shard-size calculation in
LocateEcShardNeedleInterval already uses dat_file_size when non-zero,
so populating it also matches Go's behaviour there.

Tests cover the truncated-sibling case in both ports.

Chris Lu cba2f7b1dd fix(volume_server): load orphan EC shards across disks on startup (#9212) (#9244)
* fix(volume_server): load orphan EC shards across disks on startup (#9212)

When ec.balance / ec.rebuild copies an EC shard onto a destination node
without also pinning subsequent shards to the disk that holds .ecx, the
shard ends up on a different physical disk than its index files. The
per-disk loadAllEcShards has no visibility into other DiskLocations on
the same store, so those orphan shards were silently left out of
ecVolumes and never reported to master — volume.list showed partial
counts, and ec.rebuild reported the volume as unrepairable even though
all shards were physically present.

After every DiskLocation finishes its initial pass, sweep the store for
shard files that are on disk but not yet in any EcVolume, look up the
.ecx-owning sibling disk, and load each shard against its physical disk
with dirIdx pointing at the sibling. Each shard is still registered on
its own disk's ecVolumes map so heartbeat reporting carries the right
DiskId per shard (master fix #9219 already aggregates per-disk
messages correctly).

Also fall back to dirIdx for .vif lookup when dir != dirIdx, so the
reconciliation path doesn't write a stub .vif on the shard disk and
lose the real EC config and datFileSize.

* fix(volume_server): track actual .ecx dir in cross-disk reconcile

indexEcxOwners scans both IdxDirectory and Directory to find each
volume's .ecx — the second scan covers the legacy case where index
files were written into the data dir before -dir.idx was configured
(removeEcVolumeFiles already accounts for this in disk_location_ec.go).
But the returned map dropped which directory matched, and reconcile
unconditionally passed owner.IdxDirectory to loadEcShardsWithIdxDir.

When the owner's .ecx is in Directory and IdxDirectory != Directory
(server later re-configured with -dir.idx pointing at a fresh path),
NewEcVolume opens IdxDirectory/.ecx → ENOENT, retries the same-disk
fallback at dataBaseFileName+.ecx — but dataBaseFileName uses the
*orphan* disk's data dir, not the owner's, so it ENOENTs again and the
orphan shards stay unloaded.

Track which scan dir matched in indexEcxOwners and pass it through.
Adds TestLoadEcShardsWhenOwnerEcxIsInDataDir as the regression.

Reported in PR #9244 review by @gemini-code-assist and @coderabbitai.

* refactor(storage): thread dataShardCount as a parameter into calculateExpectedShardSize

The helper used erasure_coding.DataShardsCount directly, but tests in
store_ec_orphan_shard_test.go save .vif with a local dataShards=10
constant. If the package default ever diverged from 10 (e.g. an
enterprise build), the test would write a .vif for one layout while
sizing shard files for another and silently break.

Take dataShardCount as a parameter. Existing callers
(validateEcVolume + size-validation tests + real-world tests) pass
erasure_coding.DataShardsCount unchanged. The orphan-shard tests pass
the same dataShards local they save into .vif, so the persisted shape
and the on-disk shape stay consistent.
