Chris Lu	e12052ee6b	fix(filer.sync): replicate a rename as an atomic move, not a no-op update (#9895) ... * fix(filer.sync): replicate a rename as create-then-delete, not an in-place update A rename arrives as a single metadata event carrying both the old and new entry. The filer sink was routed to UpdateEntry, which looks up the old path but issues the update against the new parent without changing the name — and the filer UpdateEntry RPC cannot move an entry. So the rename was dropped: the old path lingered and the new path never appeared (same-dir renames rewrote the old name in place). Route a real move (the sink path changed) through CreateEntry(new) then DeleteEntry(old) in both the replicator and the filer.sync/backup driver, the way the other sinks already handle it; reach UpdateEntry only for true in-place updates. Create before delete so a crash between the two leaves the entry visible rather than lost. * fix(filer.sync): derive the rename delete key like the create key, guard the watched root The rename delete leg rebuilt the old key with a raw util.Join, bypassing the sink-side key normalization the create leg gets from buildKey — so a rename could create the new entry and then fail to delete the old one under a transformed key. Build the old key through buildKey too, and skip the delete when the moved entry is the watched root itself (where the old key would resolve to the target root and recursively delete the whole sink tree). * test(filer.sync): cover the in-place update delete-then-create fallback order The recording sinks always reported foundExisting, so the fallback that an in-place update takes when the entry is missing on the sink was never run. Make it configurable and assert the fallback deletes before it recreates the same key, in both the replicator and the filer.sync drivers. * feat(filer.sync): move filer-sink renames natively via AtomicRenameEntry create-then-delete is unsafe for the filer sink: CreateEntry returns nil without creating on a transient chunk-copy error, so the paired delete could remove the only valid destination copy; a directory rename also deleted the old subtree before descendants were recreated, and left old chunks behind. Add an optional EntryMover sink capability and implement it on the filer sink via AtomicRenameEntry — one atomic, metadata-only move that relocates a whole subtree in a single transaction. Renames prefer it; sinks without a native move keep create-then-delete. When the old path is already gone (a descendant the parent rename moved, or one never replicated) MoveEntry creates the new path instead, re-checking existence with a lookup so a rolled-back move that left the old entry intact is retried rather than mistaken for gone. * docs(filer.sync): note entryMissing's gRPC not-found string fallback is deliberate	2026-06-09 12:54:28 -07:00
Chris Lu	ced2236cc6	Adjust rename events metadata format (#8854) ... * rename metadata events * fix subscription filter to use NewEntry.Name for rename path matching The server-side subscription filter constructed the new path using OldEntry.Name instead of NewEntry.Name when checking if a rename event's destination matches the subscriber's path prefix. This could cause events to be incorrectly filtered when a rename changes the file name. * fix bucket events to handle rename of bucket directories onBucketEvents only checked IsCreate and IsDelete. A bucket directory rename via AtomicRenameEntry now emits a single rename event (both OldEntry and NewEntry non-nil), which matched neither check. Handle IsRename by deleting the old bucket and creating the new one. * fix replicator to handle rename events across directory boundaries Two issues fixed: 1. The replicator filtered events by checking if the key (old path) was under the source directory. Rename events now use the old path as key, so renames from outside into the watched directory were silently dropped. Now both old and new paths are checked, and cross-boundary renames are converted to create or delete. 2. NewParentPath was passed to the sink without remapping to the sink's target directory structure, causing the sink to write entries at the wrong location. Now NewParentPath is remapped alongside the key. * fix filer sync to handle rename events crossing directory boundaries The early directory-prefix filter only checked resp.Directory (old parent). Rename events now carry the old parent as Directory, so renames from outside the source path into it were dropped before reaching the existing cross-boundary handling logic. Check both old and new directories against sourcePath and excludePaths so the downstream old-key/new-key logic can properly convert these to create or delete operations. * fix metadata event path matching * fix metadata event consumers for rename targets * Fix replication rename target keys Logical rename events now reach replication sinks with distinct source and target paths.\n\nHandle non-filer sinks as delete-plus-create on the translated target key, and make the rename fallback path create at the translated target key too.\n\nAdd focused tests covering non-filer renames, filer rename updates, and the fallback path.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix filer sync rename path scoping Use directory-boundary matching instead of raw prefix checks when classifying source and target paths during filer sync.\n\nAlso apply excludePaths per side so renames across excluded boundaries downgrade cleanly to create/delete instead of being misclassified as in-scope updates.\n\nAdd focused tests for boundary matching and rename classification.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix replicator directory boundary checks Use directory-boundary matching instead of raw prefix checks when deciding whether a source or target path is inside the watched tree or an excluded subtree.\n\nThis prevents sibling paths such as /foo and /foobar from being misclassified during rename handling, and preserves the earlier rename-target-key fix.\n\nAdd focused tests for boundary matching and rename classification across sibling/excluded directories.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix etc-remote rename-out handling Use boundary-safe source/target directory membership when classifying metadata events under DirectoryEtcRemote.\n\nThis prevents rename-out events from being processed as config updates, while still treating them as removals where appropriate for the remote sync and remote gateway command paths.\n\nAdd focused tests for update/removal classification and sibling-prefix handling.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Defer rename events until commit Queue logical rename metadata events during atomic and streaming renames and publish them only after the transaction commits successfully.\n\nThis prevents subscribers from seeing delete or logical rename events for operations that later fail during delete or commit.\n\nAlso serialize notification.Queue swaps in rename tests and add failure-path coverage.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Skip descendant rename target lookups Avoid redundant target lookups during recursive directory renames once the destination subtree is known absent.\n\nThe recursive move path now inserts known-absent descendants directly, and the test harness exercises prefixed directory listing so the optimization is covered by a directory rename regression test.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Tighten rename review tests Return filer_pb.ErrNotFound from the bucket tracking store test stub so it follows the FilerStore contract, and add a webhook filter case for same-name renames across parent directories.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix HardLinkId format verb in InsertEntryKnownAbsent error HardLinkId is a byte slice. %d prints each byte as a decimal number which is not useful for an identifier. Use %x to match the log line two lines above. * only skip descendant target lookup when source and dest use same store moveFolderSubEntries unconditionally passed skipTargetLookup=true for every descendant. This is safe when all paths resolve to the same underlying store, but with path-specific store configuration a child's destination may map to a different backend that already holds an entry at that path. Use FilerStoreWrapper.SameActualStore to check per-child and fall back to the full CreateEntry path when stores differ. * add nil and create edge-case tests for metadata event scope helpers * extract pathIsEqualOrUnder into util.IsEqualOrUnder Identical implementations existed in both replication/replicator.go and command/filer_sync.go. Move to util.IsEqualOrUnder (alongside the existing FullPath.IsUnder) and remove the duplicates. * use MetadataEventTargetDirectory for new-side directory in filer sync The new-side directory checks and sourceNewKey computation used message.NewParentPath directly. If NewParentPath were empty (legacy events, older filer versions during rolling upgrades), sourceNewKey would be wrong (/filename instead of /dir/filename) and the UpdateEntry parent path rewrite would panic on slice bounds. Derive targetDir once from MetadataEventTargetDirectory, which falls back to resp.Directory when NewParentPath is empty, and use it consistently for all new-side checks and the sink parent path.	2026-03-30 18:25:11 -07:00
