DESCRIPTION:

Extracting some 7zip files with Sailfish Archive leads to corrupt extracted files.

PRECONDITIONS:

STEPS TO REPRODUCE:

  1. Take a 7zip archive file from https://www.hvsc.c64.org/ (I tested it with HVSC_Update_81.7z)
  2. Locate the archive file in File Browser.
  3. Select Open in File Browser’s pulley menu.
  4. Select Extract all in Sailfish Archive’s pulley menu.

EXPECTED RESULT:

Extracted files should be fine.

ACTUAL RESULT:

Extracted files are corrupt, contain different data, size is okay though.

MODIFICATIONS:

ADDITIONAL INFORMATION:

I tested extracting the same file with console app p7zip 16.02 which works fine.

Confirmed.

p7z t file with that example file reports that there is something wrong with it.

It does extract files, but not all. E.g. readme.1st is missing from the results.

With p7zip-zull I get a OK result testing the archive:

$ 7z t HVSC_Update_81.7z

With p7zip (p7r) get the erroneous result. Maybe that’s a clue?

This has ‘PPMD’ while the other one just has a number 030401 (id?).

Question is, will sailfish-archive produce correct results when p7zip-full is installed?

BTW, it looks like sailfish-archive depends on Sailfish.FileManager (from sailfish-components-filemanager) which does the actual extracting.
