Ping QiuandClaude Opus 4.6	ed11a09a61	fix: CP11A-4 snapshot export/import safety — 3 bugs from review ... BUG-CP11A4-1 (HIGH): ImportSnapshot now rejects when active snapshots exist. Import overwrites the extent region that non-CoW'd snapshot blocks read from, which would silently return import data instead of snapshot-time data. New ErrImportActiveSnapshots error and snapMu-guarded check. BUG-CP11A4-2 (HIGH): Double import without AllowOverwrite now correctly rejected. Import bypasses WAL so nextLSN stays at 1; added FlagImported (Superblock.Flags bit 0) set after successful import and checked alongside nextLSN in the non-empty gate. BUG-CP11A4-3 (MED): Replaced fixed exportTempSnapID (0xFFFFFFFE) with atomic sequence counter (exportTempSnapBase + exportTempSnapSeq). Each auto-export gets a unique temp snapshot ID, preventing concurrent export races and user snapshot ID collisions. Also added beginOp()/endOp() lifecycle guards to both ExportSnapshot and ImportSnapshot, and documented the non-atomic import failure semantics. 5 new regression tests + QA-EX-3 rewritten for rejection behavior.

Ping QiuandClaude Opus 4.6	7cc6467d09	feat: CP11A-4 snapshot export/import to S3 — artifact format, engine, and transport ... Add crash-consistent snapshot export/import for single-profile block volumes. Export creates a temp snapshot, streams the full volume image with inline SHA-256, and uploads to S3. Import validates manifest + checksum and writes directly to extent region. Admin HTTP endpoints /export and /import added to the standalone iscsi-target binary. Engine: snapshot_export.go (manifest types, ExportSnapshot, ImportSnapshot) S3: snapshot_s3.go (AWS SDK v1 transport, pipe-based streaming upload) Tests: 14 engine + 9 QA adversarial = 23 new tests, all passing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-13 00:15:27 -07:00
