Subject: diffoscope: add file type (magic) information to diff output

Date: Tue, 10 Jan 2017 13:35:30 -0500

Package: diffoscope
Version: 67
Severity: wishlist

Dear Maintainer,

Please add file-type/magic information for files as this information is useful (in order to know the file content type, especially for binary files without extension)
for example:
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/buildapp.html

The ./usr/bin/buildapp file show "No file format specific differences found inside, yet data differs" without information about the file format.

I meant to add the file type information for all files, as there are more useful cases such as /usr/bin/rebar file at
https://tests.reproducible-builds.org/debian/dbdtxt/unstable/amd64/rebar_2.6.4-2.diffoscope.txt

Or when the file-content don't match the extension.

Closes: 849395 850055 850485 850501 850502 850730 850807 850850
Changes:
 diffoscope (68) unstable; urgency=medium
 .
   [ Chris Lamb ]
 .
   * Don't blow up if directory containing ELF debug symbols already exists.
     (Closes: #850807)
   * Fix .APK extration when provided with absolute filenames.
     (Closes: #850485)
   * Support comparing .ico files using img2txt. (Closes: #850730)
   * comparators.utils.file: If we don't have an archive-extraction tool (eg.
     apktool), don't blow up when attempting to unpack it.
   * Include magic file type when we know the file format but can't find
     file-specific details. (Closes: #850850)
   * Ensure fake "APK metadata" file appears first, fixing non-deterministic
     tests/output.
   * Correctly escape value of href="" elements (re. #849411)
 .
   * Optimisations:
     - Disable profiling entirely (unless enabled) for a 2%+ optimisation
     - Compile APK filename regex instead of generating it each loop.
 .
   * Logging:
     - Log tempfile cleanup process
     - Log when we add a progress observer.
     - Drop milliseconds from log output
 .
   * Misc:
     - Many unused import removals, indentation changes, etc.
     - Fix duplicated word and long line errors in debian/changelog.
     - Suggest some promotion in post-release documentation.
 .
   [ Maria Glukhova ]
   * comparators/device: don't crash when comparing a non-device against a
     device (Closes: #850055)
   * Remove archive name from apktool.yml and rename it. (Closes: #850501)
   * Zipinfo included in APK files comparison. (Closes: #850502)
     - Add some tests for APK comparator.
   * Add image metadata comparison. (Closes: #849395)
   * Ensure imagemagick version is new enough for image metadata tests.
 .
   [ Mattia Rizzolo ]
   * Skip the openssh_pub_key test if the version of ssh is < 6.9.
   * comparators/icc: rename RE_FILE_EXTENSION to RE_FILE_TYPE, as that's what
     the regular expression is looking for.
   * Make use of a new mechanism to remove a bunch of recognizes() methods
     dealing with simple RE_FILE_TYPE matching.
