  • CHANGED API Longtail_JobAPI_JobFunc renamed is_cancelled to detected_error, now contains first error returned from a job task in the same job group (if any) or ECANCELLED if job group was cancelled
    If detected_error is non-zero, try to exit (and cleanup) your task directly and return 0.
  • CHANGED_API JobAPI WaitForAllJobs now returns first error encountered in a job group for a task as well as any error in the job api itself, removing the need to book keep the error for tasks separately
  • CHANGED API Longtail_StorageAPI.OpenAppend added to Longtail_StorageAPI to open files without truncating existing data
  • CHANGED API Longtail_CreateConcurrentChunkWriteAPI changed to take source_version_index and version_diff
  • CHANGED API Longtail_ConcurrentChunkWriteAPI refactored to use asset index and open/close files instead of keeping all open during entire lifetime
    • Longtail_ConcurrentChunkWriteAPI.CreateDir now takes asset index instead of version local path
    • Longtail_ConcurrentChunkWriteAPI.Open now takes asset index instead of version local path and dropping chunk_write_count parameter
    • Longtail_ConcurrentChunkWriteAPI.Write now takes asset index instead of version local path and dropping chunk_write_count parameter
  • CHANGED API Longtail_SetMonitor callback functions refactored to accomodate changes in Longtail_ConcurrentChunkWriteAPI
  • NEW API Longtail_SetReAllocAndFree
  • NEW API Longtail_ReAlloc
  • NEW API Longtail_MemTracer_ReAlloc
  • NEW API Longtail_CompareAndSwap compare and swap with platform implementations
  • NEW API Longtail_RunJobsBatched runs jobs in batched mode to handle a job count larger than Longtail_JobAPI::GetMaxBatchCount()
  • NEW API Longtail_GetFilesRecursively2 that executes using parallel jobs improving execution speed for large file trees significantly
  • REMOVED API Longtail_SetAllocAndFree is replaced by Longtail_SetReAllocAndFree
  • REMOVED API Longtail_MemTracer_Alloc is replaced by Longtail_MemTracer_ReAlloc
  • REMOVED API Remove platform api for Read/Write mutex
    • Longtail_GetRWLockSize
    • Longtail_CreateRWLock
    • Longtail_DeleteRWLock
    • Longtail_LockRWLockRead
    • Longtail_LockRWLockWrite
    • Longtail_UnlockRWLockRead
    • Longtail_UnlockRWLockWrite
  • ADDED memtracer now tracks allocations in stb_ds
  • ADDED memtracer now tracks allocations in zstd
  • FIXED Fixed memory leaks in command tool
  • FIXED Longtail_ChangeVersion2() can now handle workloads with a block count larger than 65535
  • FIXED Bikeshed JobAPI implementation does efficient wait when task queue is full
  • FIXED Bikeshed JobAPI::CreateJobs implementation now properly drains both task channels when task queue is full
  • FIXED Make sure we retain order of assets with equal length when sorting them
  • FIXED Fixed excessive "Disk Used" increase during Longtail_ChangeVersion2 execution causing Out Of Disk space errors.
    The changes also improves performance for more common cases with smaller archive sizes (60 Gb raw data/many files) but causes a small regression compared to 0.4.1 for archives with many very large files. It is still performing much more reasonable than 0.4.0 for these cases.
