Source: strip-nondeterminism
Version: 1.13.0-2
Severity: important

Hello,

possibly you've seen the similar story in diffoscope already: The last
upload of file/libmagic (1:5.43-3, currently in experimental) broke also
the strip-nondeterminism test suite:

======================================================================
    #   Failed test 'Normalizer found for /tmp/IhdQGJbeMu/pyzip'
    #   at t/fixtures.t line 83.
    #          got: undef
    #     expected: anything else

    #   Failed test 'Test output /tmp/IhdQGJbeMu/pyzip matched expected t/fixtures/pyzip/pyzip.out'
    #   at t/fixtures.t line 89.
    # Looks like you failed 2 tests of 9.

#   Failed test 't/fixtures/pyzip/pyzip.in'
#   at t/fixtures.t line 101.
strip-nondeterminism: /tmp/IZ0B8oD7YF/encrypted.zip: ignoring encrypted zip file
# Looks like you failed 1 test of 22.
t/fixtures.t ..·
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/22 subtests·
======================================================================

As I understand it, this is result of how t/fixtures/pyzip/pyzip.in is
described by file(1):

- a /usr/bin/python3 script executable (binary data)
+ Zip archive, with extra data prepended

Now that looks a bit delicate ... if you think this is something that
should be handled in file/libmagic, let me know.

In case you're courious, the change was:

<https://github.com/file/file/commit/a92246be4a8ceff26f0d4fdaa0390fc110146d7d>:

commit a92246be4a8ceff26f0d4fdaa0390fc110146d7d
Author: Christos Zoulas <christos@zoulas.com>
Date:   Sun Oct 2 12:34:00 2022 +0000

    Recognize ZIP archives with prepended data by end-of-central-directory record
