Package: diffoscope Version: 113 Severity: normal Take the following testcase:
$ mkdir a b c $ echo 0 > c/0 $ zip a/0.zip c/0 $ echo 1 > c/0 $ zip b/0.zip c/0 $ diffoscope a b --exclude-directory-metadata=recursive --- a +++ b ├── 0.zip │ ├── c/0 │ │ @@ -1 +1 @@ │ │ -0 │ │ +1 The only way I found to exclude c/0 is: "--exclude c/0", which makes it ignore under which archive it was found, so if there is, in fact, another archive with the same path, both are excluded. And because the result of "--exclude c/0" is that there is no content difference found between the archives, diffoscope now thinks it should display format-specific differences: --- a +++ b ├── 0.zip │┄ Format-specific differences are supported for this file format but no file-specific differences were detected; falling back to a binary diff. file(1) reports: Zip archive data, at least v1.0 to extract │ @@ -1,10 +1,10 @@ │ -00000000: 504b 0304 0a00 0000 0000 3170 684e 12cd PK........1phN.. │ -00000010: 4a7e 0200 0000 0200 0000 0300 1c00 632f J~............c/ │ +00000000: 504b 0304 0a00 0000 0000 3170 684e 53fc PK........1phNS. │ +00000010: 5167 0200 0000 0200 0000 0300 1c00 632f Qg............c/ │ 00000020: 3055 5409 0003 2ef7 815c 2ef7 815c 7578 0UT......\...\ux │ -00000030: 0b00 0104 e803 0000 04e8 0300 0030 0a50 .............0.P │ -00000040: 4b01 021e 030a 0000 0000 0031 7068 4e12 K..........1phN. │ -00000050: cd4a 7e02 0000 0002 0000 0003 0018 0000 .J~............. │ +00000030: 0b00 0104 e803 0000 04e8 0300 0031 0a50 .............1.P │ +00000040: 4b01 021e 030a 0000 0000 0031 7068 4e53 K..........1phNS │ +00000050: fc51 6702 0000 0002 0000 0003 0018 0000 .Qg............. │ 00000060: 0000 0001 0000 00a4 8100 0000 0063 2f30 .............c/0 │ 00000070: 5554 0500 032e f781 5c75 780b 0001 04e8 UT......\ux..... │ 00000080: 0300 0004 e803 0000 504b 0506 0000 0000 ........PK...... │ 00000090: 0100 0100 4900 0000 3f00 0000 0000 ....I...?.....
