diffoscope 169 released 💠

[Chris Lamb]

Hi,

The diffoscope maintainers are pleased to announce the release of
version 169 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 169 includes the following changes:

  [ Chris Lamb ]
  * Optimisations:
    - Use larger buffer/block sizes when extracting files from libarchive-
      based archives.
    - Use a much-shorter CSS class (instead of "diffponct") to dramatically
      reduce uncompressed HTML output.

  * Logging improvements:
    - Don't emit "Unable to stat file" warning/debug messages; we have
      entirely-artificial directory entries such as ELF sections which, of
      course, never exist as filesystem files.
    - Don't emit a "Returning a FooContainer" logging message - we already emit
      "Instantiating a FooContainer" one and are unlikely to fail in the
      middle.
    - Format the report size logging messages when generating HTML reports.
    - Add the target directory when logging which directory we are extracting
      containers to.

  * Miscellaneous:
    - Ignore "--debug" and similar arguments when creating a (hopefully useful)
      temporary directory.
    - Ensure all internal temporary directories have useful names.
    - Clarify a comment regarding diffoscope not extracting excluded files.

  * Skip a DEX-related test if the "procyon" tool is unavailable.
