feat(filer.sync.verify): reclassify chunk-slice-order ETag diffs as CHUNK_REORDER (#10177)
* feat(filer.sync.verify): reclassify chunk-slice-order ETag diffs as CHUNK_REORDER filer.ETagChunks concatenates per-chunk MD5s in stored slice order without normalising by offset, so byte-identical content written by two different paths (S3 multipart part-completion order on the source vs filer.backup replication arrival order on the destination) yields different file ETags. filer.sync.verify reported these as ETAG_MISMATCH even though the files are equal. Add a second-pass check on every ETAG_MISMATCH: when both sides derive their ETag from chunks (no attr.Md5) and hold a manifest-free, non-overlapping chunk set that, once sorted by offset, matches element-wise on (offset, size, ETag), classify the file as CHUNK_REORDER. Such files are content-equal, so they are not counted as errors and do not affect the exit code; they are listed only at higher verbosity (weed -v=1), while the summary always shows their count. The check stays conservative: a stored attr.Md5 (order-independent content hash), a differing chunk count, an overlapping/duplicate offset (whose visible bytes are resolved by timestamp), or a manifest chunk all remain ETAG_MISMATCH. * filer.sync.verify: decline chunk-reorder fast path on empty per-chunk ETag An empty or undecodable per-chunk ETag is not a content fingerprint, so element-wise (offset, size, ETag) equality can't prove the bytes match. Treating "" == "" as content-equal could reclassify a genuine divergence as CHUNK_REORDER and drop it from the error count. Decline such chunk sets so they stay ETAG_MISMATCH. * filer.sync.verify: emit CHUNK_REORDER in JSON output regardless of -v The -v=1 gate belongs to the human text report only. Applying it before the jsonOutput branch dropped the per-file CHUNK_REORDER records from NDJSON while the summary still counted them, so a machine consumer saw a non-zero count with no records to reconcile it. Gate the text path only; JSON always emits. --------- Co-authored-by: Chris Lu <chris.lu@gmail.com> |

fix(filer.sync.verify): sort listings client-side before merge (#10117)
* fix(filer.sync.verify): sort listings client-side before merge The merge walks both filers' directory listings in lockstep and needs them in the same byte order. A filer before 4.32 with a locale SQL collation lists case-insensitively while a 4.32+ peer lists byte-ordered, so comparing two such clusters returns the same names in a different order and the merge desyncs into spurious MISSING / ONLY_IN_B. Buffer and sort each directory client-side so both sides agree on order regardless of filer version or store backend. Trades the streaming source's O(buffer) memory for O(directory) per side, fine for a one-shot verify CLI; both sides still load concurrently. Claude-Session: https://claude.ai/code/session_01BKsBdKYFNCEjeHLjJfumPF * fix(filer.sync.verify): surface listing errors before merging A listing that fails mid-stream leaves a partial, unsorted buffer. Now that both sides are fully buffered anyway, check each side's error right after the loads finish and before the merge, so partial entries can't emit spurious MISSING / ONLY_IN_B before the error aborts the run.

grpc: don't tear down the shared master connection on a caller's own timeout (#9775)
A Canceled/DeadlineExceeded from the caller's per-request context was treated like a dead channel: it closed the shared cached ClientConn and cancelled every other in-flight RPC on it with "the client connection is closing". Under a burst of concurrent chunk assigns (e.g. a large S3 multipart upload) one slow assign hitting its 10s attempt timeout could poison the connection for all the rest, cascading into a flood of 500s. Thread the caller's context into shouldInvalidateConnection and only invalidate on Canceled/DeadlineExceeded while that context is still live, which isolates the genuine stale-channel signal (a peer restart behind a k8s Service VIP). To carry the context, add a ctx parameter to the existing WithGrpcClient, WithMasterClient, and WithMasterServerClient; the master assign and volume-lookup paths pass their per-attempt context and every other caller passes context.Background(). |

refactor(command): expand "~" in all path-style CLI flags (#9306)
* refactor(command): expand "~" in all path-style CLI flags Many of weed's path-bearing flags (-s3.config, -s3.iam.config, -admin.dataDir, -webdav.cacheDir, -volume.dir.idx, TLS cert/key files, profile output paths, mount cache dirs, sftp key files, ...) were never run through util.ResolvePath, so a value like "~/iam.json" was used literally. Tilde only worked when the shell expanded it, which silently fails for the common -flag=~/path form (bash leaves the tilde literal in --opt=~/path). - Extend util.ResolvePath to also handle "~user" / "~user/rest", matching shell tilde expansion. Add unit tests. - Apply util.ResolvePath at the top of each shared start* function (s3, webdav, sftp) so mini/server/filer/standalone callers all inherit it; resolve at the few one-off use sites (mount cache dirs, volume idx folder, mini admin.dataDir, profile paths). - Drop the duplicate expandHomeDir helper from admin.go in favor of the now-equivalent util.ResolvePath. * fixup: handle comma-separated -dir flags for tilde expansion `weed mini -dir`, `weed server -dir`, and `weed volume -dir` accept comma-separated paths (`dir[,dir]...`). Calling util.ResolvePath on the whole string mishandled multi-folder values with tilde, e.g. "~/d1,~/d2" would resolve as if "d1,~/d2" were a single subpath. - Add util.ResolveCommaSeparatedPaths: split on ",", run each entry through ResolvePath, rejoin. Short-circuits when no "~" present. - Use it for *miniDataFolders (mini.go), *volumeDataFolders (server.go), and resolve each entry of v.folders in-place (volume.go) so all downstream consumers see resolved paths. - Add 7-case TestResolveCommaSeparatedPaths covering empty, single, multiple, and mixed inputs. * address PR review: metaFolder + Windows backslash - master.go: resolve *m.metaFolder at the top of runMaster so util.FullPath(*m.metaFolder) on the next line sees an expanded path. Drop the now-redundant ResolvePath in TestFolderWritable. - server.go: same treatment for *masterOptions.metaFolder, paired with the existing cpu/mem profile resolves. Drop the redundant inner ResolvePath at TestFolderWritable. - file_util.go: ResolvePath now accepts filepath.Separator as a separator after the tilde, so "~\\data" works on Windows. Other platforms keep current behaviour (backslash stays literal because it is a valid filename character in usernames and paths). - file_util_test.go: add two cases using filepath.Separator that exercise the new code path on Windows and remain a no-op on Unix. * address PR review: resolve "~" in remaining command path flags Comprehensive sweep of path-bearing flags across every weed subcommand, applying util.ResolvePath in-place at the top of each run* function so all downstream consumers see expanded paths. - webdav.go: resolve *wo.cacheDir at the top of startWebDav so mini/server/filer/standalone callers all inherit it. - mount_std.go: cpu/mem profile paths. - filer_sync.go: cpu/mem profile paths. - mq_broker.go: cpu/mem profile paths. - benchmark.go: cpuprofile output path. - backup.go: -dir resolved once at runBackup; drop the duplicated inline ResolvePath in NewVolume calls. - compact.go: -dir resolved at runCompact; drop inline ResolvePath. - export.go: -dir and -o resolved at runExport; drop inline ResolvePath in LoadFromIdx and ScanVolumeFile. - download.go: -dir resolved at runDownload; drop inline. - update.go: -dir resolved at runUpdate so filepath.Join uses the expanded path; drop inline ResolvePath in TestFolderWritable. - scaffold.go: -output expanded before filepath.Join. - worker.go: -workingDir expanded before being passed to runtime. * address PR review: resolve option-struct paths at run* entry points server.go:381 propagates s3Options.config to filerOptions.s3ConfigFile *before* startS3Server runs, which meant the filer-side code saw the unresolved tilde-prefixed pointer. Same pattern for webdavOptions and sftpOptions (and equivalent in mini.go / filer.go). The fix: hoist resolution from the shared start* functions up to the run* entry points, where every shared pointer is set up before any propagation happens. - s3.go, webdav.go, sftp.go: extract a resolvePaths() method on each Options struct that runs every path field through util.ResolvePath in-place. Idempotent. - runS3, runWebDav, runSftp: call the standalone struct's resolvePaths before starting metrics / loading security config. - runServer, runMini, runFiler: call resolvePaths on every embedded options struct, plus resolve loose flags (serverIamConfig, miniS3Config, miniIamConfig, miniMasterOptions.metaFolder, and filer's defaultLevelDbDirectory) so they're expanded before any pointer copy or use. - Drop the now-redundant inline ResolvePath at filer's defaultLevelDbDirectory composition. * address PR review: re-resolve mini -dir post-config, cover misc paths - mini.go: applyConfigFileOptions can overwrite -dir with a literal ~/data from mini.options. Re-resolve *miniDataFolders after the config-file apply, alongside the other path resolves, so the mini filer no longer ends up with a literal ~/data/filerldb2. - benchmark.go: resolve *b.idListFile (-list). - filer_sync.go: resolve *syncOptions.aSecurity / .bSecurity (-a.security / -b.security) before LoadClientTLSFromFile. - filer_cat.go: resolve *filerCat.output (-o) before os.OpenFile. - admin.go: drop trailing blank line at EOF (git diff --check). * address PR review: resolve -a.security/-b.security/-config before use Three follow-up fixes: - filer_sync.go: the -a.security / -b.security resolves were placed *after* LoadClientTLSFromFile / LoadHTTPClientFromFile were called, so weed filer.sync -a.security=~/a.toml still passed the literal tilde path. Hoist the resolves above the security-loading block so TLS clients see expanded paths. - filer_sync_verify.go: same flag pair was never resolved at all in the verify command; resolve at the top of runFilerSyncVerify. - filer_meta_backup.go: -config (the backup_filer.toml path) was passed directly to viper. Resolve at the top of runFilerMetaBackup. - mini.go: master.dir defaulted to the entire comma-joined miniDataFolders. With weed mini -dir=~/d1,~/d2 (or any multi-dir setup), TestFolderWritable then stat'd the joined string instead of a single directory. Default to the first entry via StringSplit to mirror the disk-space calculation a few lines below, and drop the now-redundant ResolvePath in TestFolderWritable. |

feat(filer.sync): add -verifySync mode to filer.sync for cross-cluster file comparison (#9284)
* Add -verifySync flag to filer.sync for cross-cluster file comparison
Add a verification mode to filer.sync that compares entries between two
filers without performing actual synchronization. Uses directory-level
sorted merge of ListEntries to detect missing files, size mismatches,
and ETag mismatches. Supports -isActivePassive for unidirectional check
and -modifyTimeAgo to skip recently modified files during sync lag.
* Add mtime annotation and JSON output to filer.sync -verifySync
Add automatic mtime relation analysis for SIZE_MISMATCH and
ETAG_MISMATCH diffs, and an NDJSON output mode for external tooling.
mtime classification:
- B_NEWER => "late_updates_skip_likely" hint. Surfaces the case
where target has a stub entry whose mtime is ahead of source's
real file, causing UpdateEntry's mtime guard in filersink to
permanently skip the update.
- A_NEWER => "sync_lag_or_event_miss" hint.
- EQUAL => no hint (chunk-level issue suspected).
Text output example:
[SIZE_MISMATCH] /path (a=996, b=0, B newer +274d [late-updates skip likely])
Add -verifyJsonOutput flag. When set, emits one JSON object per
line (NDJSON) for diffs and a final SUMMARY object, suitable for
piping into external diagnostic pipelines.
Concurrent writes from the directory worker pool are now serialized
via outputMu to keep both text lines and JSON records atomic.
* fix(filer.sync): use shared global semaphore in verifySync to bound goroutine explosion
Replace the per-call local semaphore in compareDirectory with a single
shared semaphore created in runVerifySync. The old per-level semaphore
applied a limit of verifySyncConcurrency only within each directory level,
allowing effective concurrency to grow as verifySyncConcurrency^depth on
deep trees.
The shared semaphore is held only for each directory's I/O phase
(listEntries + merge) and released before recursing into subdirectories,
so a parent never blocks waiting for children to acquire slots — which
would deadlock once tree depth exceeds the semaphore capacity.
Extract the capacity into a named constant (verifySyncConcurrency = 5)
with a comment explaining the memory vs. performance trade-off.
Add unit tests:
- correctness: missing file, only-in-B, size mismatch, active-passive mode
- concurrency bound: peak concurrent listings ≤ verifySyncConcurrency
- no-deadlock: binary tree of depth 10 completes within timeout
* fix(filer.sync): stream directory entries to prevent OOM on large directories
Replace the listEntries helper (which accumulated all entries into a
single []filer_pb.Entry slice) with an entryStream type that pages
through the directory in the background and forwards entries one at a
time through a buffered channel. Memory per directory comparison is now
O(channel buffer size = 64) regardless of how many entries the directory
contains.
Key design points:
- entryStream wraps a goroutine + buffered channel with a one-entry
lookahead (peek/advance) so the two-pointer sorted merge in
compareDirectory can work without buffering any full listing.
- A child context (mergeCtx) is passed to both stream goroutines so
they are cancelled promptly if compareDirectory returns early (e.g.
on error); the ctx.Done() select arm in the callback prevents
goroutine leaks when the consumer stops reading.
- stream.err is written by the goroutine before close(ch), so it is
safe to read after the channel is exhausted (Go memory model:
channel close happens-before the zero-value receive).
- countMissingRecursive is rewritten to use ReadDirAllEntries with a
direct callback, eliminating its own slice allocation.
- listEntries is removed; it is no longer called anywhere.
* fix(filer.sync): address verifySync review findings
Four real bugs found and fixed; one finding already resolved (shared
semaphore was introduced in a prior commit).
path.Join for child paths (filer_sync_verify.go)
fmt.Sprintf("%s/%s", dir, name) produced "//name" when dir was "/".
Replace all child-path concatenations with path.Join so root-level
walks emit clean paths.
cutoffTime check for ONLY_IN_B entries (filer_sync_verify.go)
The B-only branch ignored -modifyTimeAgo, so files recently written
to B were reported as ONLY_IN_B instead of being skipped. Mirror the
A-side mtime guard: skip and increment skippedRecent when the entry
is newer than cutoffTime.
Summary emitted before error check (filer_sync_verify.go)
A filer I/O error mid-walk still caused a SUMMARY record (or text
summary) to be printed, making partial runs appear complete. Move the
error check to before summary emission; on error, return immediately
without printing any summary.
Return false on verification failure (filer_sync.go)
runVerifySync returned true (exit 0) even when diffs were found or the
walk failed. Return false so the main binary sets exit status 1,
consistent with how all other commands signal failure.
* test(filer.sync): add missing verifySync test coverage
Four new tests covering gaps identified during review:
TestVerifySyncETagMismatch
Verifies that two files with identical size but different Md5 checksums
are counted as etagMismatch (not sizeMismatch). Exercises the second
branch of compareEntries that was previously untested.
TestVerifySyncCutoffTime (4 subtests)
A-only recent — recent file skipped (skippedRecent++), not MISSING
A-only old — old file reported as MISSING
B-only recent — recent file skipped (skippedRecent++), not ONLY_IN_B
B-only old — old file reported as ONLY_IN_B
The B-only subtests specifically cover the cutoffTime fix added in the
previous commit.
TestVerifySyncRootPath
Regression for the path.Join fix: walks from "/" and verifies that the
child directory is reached and compared correctly (the old Sprintf
produced "//data" which would silently produce wrong results).
Asserts dirCount=2 and fileCount=1 to confirm the full tree is walked.
* fix(filer.sync): use os.Exit(2) instead of return false on verify failure
return false triggered weed.go's error handler which printed the full
command usage — appropriate for invalid arguments, not for a completed
verification that found differences. Use os.Exit(2) consistent with
the existing pattern in filer_sync.go (lines 251, 293).
* refactor(filer.sync.verify): split verify into its own command
The verify mode is a one-shot batch operation with a fundamentally
different lifecycle from the long-running sync subscriber, and most of
filer.sync's flags (replication, metrics port, debug pprof, concurrency,
etc.) do not apply to it. Extract it into a sibling command alongside
filer.copy/filer.backup/filer.export rather than a flag mode on
filer.sync.
Also rename modifyTimeAgo to modifiedTimeAgo (grammatical) and drop the
verifyJsonOutput prefix to plain jsonOutput now that the verify context
is implicit in the command name.
* fix(filer.sync.verify): address review comments
- Bounded worker pool: cap subdirectory goroutines per level via a
jobs channel and min(verifySyncConcurrency, len(subDirs)) workers
instead of spawning one goroutine per child. Wide directories no
longer park ~2KB per queued goroutine.
- Don't gate recursion on a directory's mtime: a fresh child write
bumps the parent mtime, but older files inside should still be
reported as missing. Always recurse for missing-in-B directories
and apply the cutoff per-file inside countMissingRecursive.
- Apply -modifiedTimeAgo symmetrically: matched-name files now skip
the comparison when EITHER side is recently modified, not just A.
This restores lag tolerance when B was just rewritten.
Adds tests for both new behaviors and a shared isTooRecent helper.
