[diffoscope] diffoscope 164 released 💠

[Chris Lamb]

Hi,

The diffoscope maintainers are pleased to announce the release of
version 164 of diffoscope.

diffoscope tries to get to the bottom of what makes files or
directories different. It will recursively unpack archives of many
kinds and transform various binary formats into more human-readable
form to compare them. It can compare two tarballs, ISO images, or PDF
just as easily.

Version 164 includes the following changes:

  [ Chris Lamb ]
  * Truncate jsondiff differences at 512 bytes lest they consume the entire page.
  * Wrap our external call to cmp(1) with a profile (to match the internal
    profiling).
  * Add a note regarding the specific ordering of the new
    all_tools_are_listed test.

  [ Dimitrios Apostolou ]
  * Performance improvements:
    - Improve speed of has_same_content by spawning cmp(1) less frequently.
    - Log whenever the external cmp(1) command is spawn.ed
    - Avoid invoking external diff for identical, short outputs.
  * Rework handling of temporary files:
    - Clean up temporary directories as we go along, instead of at the end.
    - Delete FIFO files when the FIFO feeder's context manager exits.

  [ Mattia Rizzolo ]
  * Fix a number of potential crashes in --list-debian-substvars, including
    explicitly listing lipo and otool as external tools.
   - Remove redundant code and let object destructors clean up after themselves.

  [ Conrad Ratschan ]
  * Add a comparator for Flattened Image Trees (FIT) files, a boot image format
    used by U-Boot.
