    1. Errors due to changed `.tar.*` MIME typeClosed

      After updating from file version 5.47 to version 5.48 in patool tests newly report the MIME type of the test files t.tar.bz2 as application/x-bzip2 but for some reason expect application/x-tar, causing detection logic to fail. Other compression types are also reported as changed:…

    2. using "zpaqfranz" instead of "zpaq"?Closed

      zpaq 7.15 will be 10 years old next month. zpaqfranz 64.8 is 10 days old. not sure if people actually use the original anymore. the command line options "x", "l" and "a" are the same. patoolib/init.py line 391: None: ('zpaqfranz',), or (to be safe) None: ('zpaqfranz', 'zpaq'),

    5. Incorrectly detecting rar support for 7zClosed

      I was getting the same error as #149 after a system update where p7zip was replaced with the upstream 7zip package on archlinux. After looking through the code a bit, I found that util.p7zipsupportsrar() was looking for rar codecs that it will not find on my system, preventing me…

    7. `test_archive` does not raise exception on incorrect passwordOpen

    8. 7z not detected when extracting rarClosed

      As mentioned in #149 and #175 I am experiencing an issue with patool detecting 7zip. I'm not sure if I should be opening a separate issue. However #149 appears to be an issue with a zip being detected as a rar and #175 is asking for version checking which I'm not sure is the full…

    9. Incorrectly using `7z` executable to extract `.zip` fileClosed

      Version: patool 3.1.0 Attempting to extract a zip file seems to incorrectly use p7zip's 7z executable. This results in a failure to properly extract. This does NOT happen if there are no valid 7z executables on the PATH, which leads me to believe there's a weird case where it's…

    10. Add support for using `unar` as a replacement for `unace`, `unadf`, `unalz`, and othersClosed

      unar can support quite a large variety of formats internally. We already have support for it's use as extract only for ace files, it would be great to allow it to be used for any others that support it.

    11. Use "zpaqfranz test" instead of listOpen

      testzpaq() is basically the same a listzpaq() except the 't' (no verbose, no passwords) according to my testing "zpaqfranz" is used, even if a "zpaq" is installed in the same bin directory. but i'm not sure if this is just a coincidence.

    12. No defense against `../` relative path traversal during extractionOpen

      patool extracts archives into a temporary directory (extractarchive) then optionally moves the result up one level (cleanupoutdir). This confines absolute-path attacks (backend tools strip leading /), but there is no central sanitization of ../ relative path components in archive…

    13. What are the dependencies?Closed

      The concept is good. But nowhere have you mentioned the list of dependencies required to explore the full potential of the tool. Can you update your readme or doc/install.md to make it clear to the users?

    15. Logging module leads to duplicated log messagesClosed

      The following script leads to duplicated log messages: Probably because the message is propagated to the root handler set up by logging.basicConfig. Maybe disable propagate? Or maybe no longer use a custom hander and let the root logger decide?
