1.2.4 (newest version on OPAM)

  • Adapted to Angstrom 0.7.0 API changes
    • This is completely internal
  • Added --only-pick-uid option to rescue mode
    • This allows only picking sbx blocks of specific uid when rescuing
    • This is useful when you only only want to rescue one specific file
  • Renamed --only-pick option to --only-pick-block in rescue mode

1.2.3 (published on OPAM)

  • Message text polishing
  • Fixed division by zero error/exception in progress reporting when number of total units is 0
    • The error/exception affects all four modes when dealing with files of size 0 bytes
  • Added only-pick option to rescue mode
    • This allows asking osbx to only pick some type(s) of blocks during rescuing
  • Added seek position checking code for rescue log file
    • This prevents showing "Unknown error" in rescue mode when logged bytes processed field exceeds the file size
  • File UID hex is printed in upper case
  • Added from, to options to rescue mode
    • This allows specifying range of file to scan for data rescuing
  • Added from, to options to show mode(previously only skip-to option exists for show)
    • This allows specifying range of file to scan for metadata
  • Added force-misalign option to rescue and show mode
    • This allows disabling automatic rounding down of from byte parameter

1.2.2 (published on OPAM)

  • Optimized decoding code to speed up reference block scanning
    • Avoids decoding the sbx block in full when already has a block of that type
  • Added no-meta option to decode mode
    • If enabled, saves time by not looking for metadata block actively
  • Added code to handle negative parameters
    • decode
      • show-fail-max
    • show
      • find-max
      • skip-to

1.2.1 (published on OPAM)

  • Optmized CRC-CCITT
    • Changed fake_uint16 to use int instead of int64
    • This makes encoding and decoding significantly faster
    • Other block related operations are also faster in general
  • Added silent option to all modes
    • Only affects progress text printing

1.2.0 (superseded by 1.2.1, not published on OPAM)

  • Fixed slightly off progress counting in Decode
  • Optimized decoding code to avoid searching for a reference block twice
  • Added command line option for decode and show
    • Added --show-fail-max for decode
    • Added --find-max for show
  • Updated show command to also show sbx container version
  • Added position tracking to show mode
  • Added --skip-to for show for skipping to some byte
  • Improved progress reporting
    • Replaced fraction with progress bar
    • Made the rate more readable
    • General overhaul to improve quality
  • Optimized performance of progress printing code and log writing code

1.1.1 (published on OPAM)

  • Removed dependency on Core_kernel
    • 1.1.1 uses a custom replacement of Core_kernel.protect and OCaml Pervasives channels

1.1.0 (superseded by 1.1.1, not published on OPAM)

  • Added "show" command
  • Switched from using Core to Core_kernel
    • Now osbx can be compiled on Windows
  • Switched to a pure OCaml implementation of CRC-CCITT
    • Implementation is translated from libcrc implementation
  • Added support for multiple hash functions
    • added support for sha1 sha256 sha512 and blake2b-512
    • in prior versions, only sha256 was supported
  • Encoding, decoding now try to be "smart" (see their man pages)
  • Fixed Multihash encoding, decoding of BLAKE2 hashes

1.0.1 (published on OPAM)

  • Changed rescue mode to use the original bytes of the file, rather than regenerating the block bytes itself
  • Fixed jbuild file to work on macOS when building
  • Added graceful handling of Ctrl-C breaks in rescue mode
    • log file stays valid after being interrupted
    • in 1.0.0, log file may be empty/broken when osbx is interrupted during rescuing
  • Better progress reporting for encoding, decoding and rescuing
  • Fixed progress reporting issues with rescuing
    • in 1.0.0, rescue mode only does a progress report when it outputs a block, rather than after scanning the block bytes
    • this makes osbx outputs no log when the scanned file section is large and contains no valid blocks
  • Fixed log writing with rescuing
    • in 1.0.0, rescue mode only writes to log file when a valid block is found
    • now it is changed to update log on bytes read, not on blocks written
  • Updated file size retrieval function to act correctly when dealing with block devices
    • Changed File_utils.getsize to use Core.In_channel.length instead of Unix.LargeFile.stat
  • Added progress reporting for hash in decode mode

1.0.0 (published on OPAM)

  • Base version
