* compare chunks by timestamp
* fix slab clearing error
* fix test compilation
* move oldest chunk to sealed, instead of by fullness
* lock on fh.entryViewCache
* remove verbose logs
* revert slat clearing
* less logs
* less logs
* track write and read by timestamp
* remove useless logic
* add entry lock on file handle release
* use mem chunk only, swap file chunk has problems
* comment out code that maybe used later
* add debug mode to compare data read and write
* more efficient readResolvedChunks with linked list
* small optimization
* fix test compilation
* minor fix on writer
* add SeparateGarbageChunks
* group chunks into sections
* turn off debug mode
* fix tests
* fix tests
* tmp enable swap file chunk
* Revert "tmp enable swap file chunk"
This reverts commit 985137ec47.
* simple refactoring
* simple refactoring
* do not re-use swap file chunk. Sealed chunks should not be re-used.
* comment out debugging facilities
* either mem chunk or swap file chunk is fine now
* remove orderedMutex as *semaphore.Weighted
not found impactful
* optimize size calculation for changing large files
* optimize performance to avoid going through the long list of chunks
* still problems with swap file chunk
* rename
* tiny optimization
* swap file chunk save only successfully read data
* fix
* enable both mem and swap file chunk
* resolve chunks with range
* rename
* fix chunk interval list
* also change file handle chunk group when adding chunks
* pick in-active chunk with time-decayed counter
* fix compilation
* avoid nil with empty fh.entry
* refactoring
* rename
* rename
* refactor visible intervals to *list.List
* refactor chunkViews to *list.List
* add IntervalList for generic interval list
* change visible interval to use IntervalList in generics
* cahnge chunkViews to *IntervalList[*ChunkView]
* use NewFileChunkSection to create
* rename variables
* refactor
* fix renaming leftover
* renaming
* renaming
* add insert interval
* interval list adds lock
* incrementally add chunks to readers
Fixes:
1. set start and stop offset for the value object
2. clone the value object
3. use pointer instead of copy-by-value when passing to interval.Value
4. use insert interval since adding chunk could be out of order
* fix tests compilation
* fix tests compilation
