chrislu	c56a0a0ebd	fix: handle 'default' collection filter in cluster volumes page - Update matchesCollection to recognize 'default' as filter for empty collection - Remove incorrect conversion of 'default' to empty string in handlers - Fixes issue where ?collection=default would show all collections instead of just default collection	2 months ago
Chris Lu	208d7f24f4	Erasure Coding: Ec refactoring (#7396 ) * refactor: add ECContext structure to encapsulate EC parameters - Create ec_context.go with ECContext struct - NewDefaultECContext() creates context with default 10+4 configuration - Helper methods: CreateEncoder(), ToExt(), String() - Foundation for cleaner function signatures - No behavior change, still uses hardcoded 10+4 * refactor: update ec_encoder.go to use ECContext - Add WriteEcFilesWithContext() and RebuildEcFilesWithContext() functions - Keep old functions for backward compatibility (call new versions) - Update all internal functions to accept ECContext parameter - Use ctx.DataShards, ctx.ParityShards, ctx.TotalShards consistently - Use ctx.CreateEncoder() instead of hardcoded reedsolomon.New() - Use ctx.ToExt() for shard file extensions - No behavior change, still uses default 10+4 configuration * refactor: update ec_volume.go to use ECContext - Add ECContext field to EcVolume struct - Initialize ECContext with default configuration in NewEcVolume() - Update LocateEcShardNeedleInterval() to use ECContext.DataShards - Phase 1: Always uses default 10+4 configuration - No behavior change * refactor: add EC shard count fields to VolumeInfo protobuf - Add data_shards_count field (field 8) to VolumeInfo message - Add parity_shards_count field (field 9) to VolumeInfo message - Fields are optional, 0 means use default (10+4) - Backward compatible: fields added at end - Phase 1: Foundation for future customization * refactor: regenerate protobuf Go files with EC shard count fields - Regenerated volume_server_pb/.go with new EC fields - DataShardsCount and ParityShardsCount accessors added to VolumeInfo - No behavior change, fields not yet used refactor: update VolumeEcShardsGenerate to use ECContext - Create ECContext with default configuration in VolumeEcShardsGenerate - Use ecCtx.TotalShards and ecCtx.ToExt() in cleanup - Call WriteEcFilesWithContext() instead of WriteEcFiles() - Save EC configuration (DataShardsCount, ParityShardsCount) to VolumeInfo - Log EC context being used - Phase 1: Always uses default 10+4 configuration - No behavior change * fmt * refactor: update ec_test.go to use ECContext - Update TestEncodingDecoding to create and use ECContext - Update validateFiles() to accept ECContext parameter - Update removeGeneratedFiles() to use ctx.TotalShards and ctx.ToExt() - Test passes with default 10+4 configuration * refactor: use EcShardConfig message instead of separate fields * optimize: pre-calculate row sizes in EC encoding loop * refactor: replace TotalShards field with Total() method - Remove TotalShards field from ECContext to avoid field drift - Add Total() method that computes DataShards + ParityShards - Update all references to use ctx.Total() instead of ctx.TotalShards - Read EC config from VolumeInfo when loading EC volumes - Read data shard count from .vif in VolumeEcShardsToVolume - Use >= instead of > for exact boundary handling in encoding loops * optimize: simplify VolumeEcShardsToVolume to use existing EC context - Remove redundant CollectEcShards call - Remove redundant .vif file loading - Use v.ECContext.DataShards directly (already loaded by NewEcVolume) - Slice tempShards instead of collecting again * refactor: rename MaxShardId to MaxShardCount for clarity - Change from MaxShardId=31 to MaxShardCount=32 - Eliminates confusing +1 arithmetic (MaxShardId+1) - More intuitive: MaxShardCount directly represents the limit fix: support custom EC ratios beyond 14 shards in VolumeEcShardsToVolume - Add MaxShardId constant (31, since ShardBits is uint32) - Use MaxShardId+1 (32) instead of TotalShardsCount (14) for tempShards buffer - Prevents panic when slicing for volumes with >14 total shards - Critical fix for custom EC configurations like 20+10 * fix: add validation for EC shard counts from VolumeInfo - Validate DataShards/ParityShards are positive and within MaxShardCount - Prevent zero or invalid values that could cause divide-by-zero - Fallback to defaults if validation fails, with warning log - VolumeEcShardsGenerate now preserves existing EC config when regenerating - Critical safety fix for corrupted or legacy .vif files * fix: RebuildEcFiles now loads EC config from .vif file - Critical: RebuildEcFiles was always using default 10+4 config - Now loads actual EC config from .vif file when rebuilding shards - Validates config before use (positive shards, within MaxShardCount) - Falls back to default if .vif missing or invalid - Prevents data corruption when rebuilding custom EC volumes * add: defensive validation for dataShards in VolumeEcShardsToVolume - Validate dataShards > 0 and <= MaxShardCount before use - Prevents panic from corrupted or uninitialized ECContext - Returns clear error message instead of panic - Defense-in-depth: validates even though upstream should catch issues * fix: replace TotalShardsCount with MaxShardCount for custom EC ratio support Critical fixes to support custom EC ratios > 14 shards: disk_location_ec.go: - validateEcVolume: Check shards 0-31 instead of 0-13 during validation - removeEcVolumeFiles: Remove shards 0-31 instead of 0-13 during cleanup ec_volume_info.go ShardBits methods: - ShardIds(): Iterate up to MaxShardCount (32) instead of TotalShardsCount (14) - ToUint32Slice(): Iterate up to MaxShardCount (32) - IndexToShardId(): Iterate up to MaxShardCount (32) - MinusParityShards(): Remove shards 10-31 instead of 10-13 (added note about Phase 2) - Minus() shard size copy: Iterate up to MaxShardCount (32) - resizeShardSizes(): Iterate up to MaxShardCount (32) Without these changes: - Custom EC ratios > 14 total shards would fail validation on startup - Shards 14-31 would never be discovered or cleaned up - ShardBits operations would miss shards >= 14 These changes are backward compatible - MaxShardCount (32) includes the default TotalShardsCount (14), so existing 10+4 volumes work as before. * fix: replace TotalShardsCount with MaxShardCount in critical data structures Critical fixes for buffer allocations and loops that must support custom EC ratios up to 32 shards: Data Structures: - store_ec.go:354: Buffer allocation for shard recovery (bufs array) - topology_ec.go:14: EcShardLocations.Locations fixed array size - command_ec_rebuild.go:268: EC shard map allocation - command_ec_common.go:626: Shard-to-locations map allocation Shard Discovery Loops: - ec_task.go:378: Loop to find generated shard files - ec_shard_management.go: All 8 loops that check/count EC shards These changes are critical because: 1. Buffer allocations sized to 14 would cause index-out-of-bounds panics when accessing shards 14-31 2. Fixed arrays sized to 14 would truncate shard location data 3. Loops limited to 0-13 would never discover/manage shards 14-31 Note: command_ec_encode.go:208 intentionally NOT changed - it creates shard IDs to mount after encoding. In Phase 1 we always generate 14 shards, so this remains TotalShardsCount and will be made dynamic in Phase 2 based on actual EC context. Without these fixes, custom EC ratios > 14 total shards would cause: - Runtime panics (array index out of bounds) - Data loss (shards 14-31 never discovered/tracked) - Incomplete shard management (missing shards not detected) * refactor: move MaxShardCount constant to ec_encoder.go Moved MaxShardCount from ec_volume_info.go to ec_encoder.go to group it with other shard count constants (DataShardsCount, ParityShardsCount, TotalShardsCount). This improves code organization and makes it easier to understand the relationship between these constants. Location: ec_encoder.go line 22, between TotalShardsCount and MinTotalDisks * improve: add defensive programming and better error messages for EC Code review improvements from CodeRabbit: 1. ShardBits Guardrails (ec_volume_info.go): - AddShardId, RemoveShardId: Reject shard IDs >= MaxShardCount - HasShardId: Return false for out-of-range shard IDs - Prevents silent no-ops from bit shifts with invalid IDs 2. Future-Proof Regex (disk_location_ec.go): - Updated regex from \.ec[0-9][0-9] to \.ec\d{2,3} - Now matches .ec00 through .ec999 (currently .ec00-.ec31 used) - Supports future increases to MaxShardCount beyond 99 3. Better Error Messages (volume_grpc_erasure_coding.go): - Include valid range (1..32) in dataShards validation error - Helps operators quickly identify the problem 4. Validation Before Save (volume_grpc_erasure_coding.go): - Validate ECContext (DataShards > 0, ParityShards > 0, Total <= MaxShardCount) - Log EC config being saved to .vif for debugging - Prevents writing invalid configs to disk These changes improve robustness and debuggability without changing core functionality. * fmt * fix: critical bugs from code review + clean up comments Critical bug fixes: 1. command_ec_rebuild.go: Fixed indentation causing compilation error - Properly nested if/for blocks in registerEcNode 2. ec_shard_management.go: Fixed isComplete logic incorrectly using MaxShardCount - Changed from MaxShardCount (32) back to TotalShardsCount (14) - Default 10+4 volumes were being incorrectly reported as incomplete - Missing shards 14-31 were being incorrectly reported as missing - Fixed in 4 locations: volume completeness checks and getMissingShards 3. ec_volume_info.go: Fixed MinusParityShards removing too many shards - Changed from MaxShardCount (32) back to TotalShardsCount (14) - Was incorrectly removing shard IDs 10-31 instead of just 10-13 Comment cleanup: - Removed Phase 1/Phase 2 references (development plan context) - Replaced with clear statements about default 10+4 configuration - SeaweedFS repo uses fixed 10+4 EC ratio, no phases needed Root cause: Over-aggressive replacement of TotalShardsCount with MaxShardCount. MaxShardCount (32) is the limit for buffer allocations and shard ID loops, but TotalShardsCount (14) must be used for default EC configuration logic. * fix: add defensive bounds checks and compute actual shard counts Critical fixes from code review: 1. topology_ec.go: Add defensive bounds checks to AddShard/DeleteShard - Prevent panic when shardId >= MaxShardCount (32) - Return false instead of crashing on out-of-range shard IDs 2. command_ec_common.go: Fix doBalanceEcShardsAcrossRacks - Was using hardcoded TotalShardsCount (14) for all volumes - Now computes actual totalShardsForVolume from rackToShardCount - Fixes incorrect rebalancing for volumes with custom EC ratios - Example: 5+2=7 shards would incorrectly use 14 as average These fixes improve robustness and prepare for future custom EC ratios without changing current behavior for default 10+4 volumes. Note: MinusParityShards and ec_task.go intentionally NOT changed for seaweedfs repo - these will be enhanced in seaweed-enterprise repo where custom EC ratio configuration is added. * fmt * style: make MaxShardCount type casting explicit in loops Improved code clarity by explicitly casting MaxShardCount to the appropriate type when used in loop comparisons: - ShardId comparisons: Cast to ShardId(MaxShardCount) - uint32 comparisons: Cast to uint32(MaxShardCount) Changed in 5 locations: - Minus() loop (line 90) - ShardIds() loop (line 143) - ToUint32Slice() loop (line 152) - IndexToShardId() loop (line 219) - resizeShardSizes() loop (line 248) This makes the intent explicit and improves type safety readability. No functional changes - purely a style improvement.	3 months ago
