Chris LuandDevin	8ad2f29e3e	shell: let volume.deleteEmpty drop volumes with no live needles (#11437) ... * shell: let volume.deleteEmpty drop volumes with no live needles The candidate check only accepted a .dat at superblock size, so a volume whose every needle was deleted still had to be vacuumed first — minutes of compaction to rewrite bytes that were all garbage anyway. FileCount counts every indexed entry and DeleteCount every entry made garbage by overwrite or delete, so FileCount <= DeleteCount means nothing live remains and the volume can be unlinked directly. The quietFor guard is unchanged. * volume server: add only_garbage VolumeDelete guard VolumeDelete(only_empty) refuses every volume that ever held data, so a volume whose needles are all deleted could only be removed after a vacuum rewrote it. The new only_garbage flag deletes only when the byte counters show nothing live: DeletedSize covering all of ContentSize, the same all-garbage state vacuum measures. Byte counters are used because the file/delete counts drift on index reload. * rust volume: mirror only_garbage VolumeDelete guard Same check as the Go server: a volume deletes under only_garbage when its deleted bytes cover all content bytes. The grpc handler rejects before the store drops the volume from its map, since destroy errors after removal would still unmount it. * volume delete: let either enabled check pass, keep onlyEmpty on the wire An upgraded shell sending only_garbage to a pre-upgrade server would be read as an unconditional delete (field ignored, only_empty false). The request now keeps only_empty set so old servers check emptiness and refuse, while new servers delete when either check passes. * volume.deleteEmpty: skip remote-backed and protected read-only volumes A remote-tiered replica shares its cloud object with the other replicas, so keepRemoteData=false on one delete removes data they still reference. Protected read-only volumes are quarantined or under maintenance, which is exactly when a replica should not be dropped. * volume delete: validate guarded copies across disks before deleting * volume delete: hold copy locks across guarded validate-and-delete CheckVolumeDeletable released each copy's locks before Destroy ran, so a write landing on a later copy between the two passes refused its destroy after earlier copies were already removed. Pin every copy's dataFileAccessLock (and its location's volumesLock) across validation and removal so a refused delete leaves all copies intact. * volume delete: send deleted-volume notices after releasing locks A blocking send on a full DeletedVolumesChan under volumesLock can stall the heartbeat loop that drains it while it waits on the same locks. Collect the notices under the lock span and send after release. * pb: restore generated-file cosmetics to match the repo's protoc version Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>	2026-09-26 15:53:39 +08:00
Chris Lu	8112f2733a	filer: batch exact lookup RPC, authoritative volume lookup, VolumeDelete status codes (#11122) ... * storage: make DeleteVolume errors inspectable with errors.Is An absent volume wraps ErrVolumeNotFound and an only-empty refusal now wraps ErrVolumeNotEmpty with %w instead of %v, so callers no longer have to match on the message. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * volume server: return NotFound and FailedPrecondition from VolumeDelete An absent volume maps to codes.NotFound and a non-empty volume under only_empty to codes.FailedPrecondition, so a caller retiring a volume can treat NotFound as already done. The store message is kept in the status description because the EC empty-replica sweep still matches on it. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * wdclient: add LookupVolumeIdsAuthoritative Bypasses the vid map and asks the provider directly, for callers where a stale positive location is unsafe. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * filer: add LookupDirectoryEntries batch lookup RPC Up to 4096 exact-path lookups in one call, resolved concurrently with results in request order, plus one deduplicated location lookup for every volume the returned entries reference and per-fid read tokens when the filer signs reads. unavailable_volume_is_miss lets cache-style callers take an entry whose volume has no live location as a miss, resolved against the master rather than the filer's location cache. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * filer: test that an expired file entry is deleted on read Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * filer: test that AssignVolume and CreateEntry resolve the same TTL rule Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * master: refuse partial lookups while warming up LookupVolume returned Unavailable during warm-up only when every requested volume was missing. A batch mixing a reported volume with one whose server has not reconnected yet came back as a partial answer with a per-volume not-found, which a caller treating the master as authoritative reads as gone. Any not-found during warm-up is now Unavailable, which callers already retry. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * filer: build batch test requests instead of copying a proto message Copying a generated message copies its internal mutex, which go vet's copylocks check rejects. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * filer: match ErrNotFound with errors.Is and state the miss rule's contract A wrapped not-found from the store would otherwise be reported as an error rather than a miss. The comments now say why a nil location map is the only sign of an unanswered lookup: the provider returns nil when it got no answer and a populated map, with unserved volumes reported as errors, when the master did answer. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * volume server: map absent and non-empty VolumeDelete errors in the Rust server Matches the Go server: an absent volume is NotFound and an only_empty refusal is FailedPrecondition instead of Internal, with the messages the EC empty-replica sweep matches on. Claude-Session: https://claude.ai/code/session_01T4MEV3ETqFFKN46Uu2ZrUm * filer: test that a malformed entry keeps its error outside cache mode Same test file as the enterprise tree, so the next sync sees one version.
