Created attachment 1117307 [details] Example mime type definition Description of problem: 1. Install the attached mime type xml file under /usr/share/mime/packages 2. Change the mathematica section of /usr/share/mime/packages/freedesktop.org.xml to have a lower weight and priority ie.: <glob weight="30" pattern="*.nb"/> and <magic priority="30"> 3. Run update-mime-database /usr/share/mime 4. At this point, the definition in application-vnd.wolfram.nb.xml should be having priority over the one in freedesktop.org.xml for files with the extension .nb, and so the mimetype should be detected as application/vnd.wolfram.nb rather than application/mathematica 5. However: $ xdg-mime query filetype junk.nb application/mathematica $ gvfs-info junk.nb display name: junk.nb edit name: junk.nb name: junk.nb type: regular size: 4 uri: file:///home/jgu/tmp/junk.nb attributes: standard::type: 1 standard::name: junk.nb standard::display-name: junk.nb standard::edit-name: junk.nb standard::copy-name: junk.nb standard::icon: application-mathematica, x-office-document standard::content-type: application/mathematica standard::fast-content-type: application/vnd.wolfram.nb $ mimetype junk.nb junk.nb: application/vnd.wolfram.nb $ kmimetypefinder junk.nb application/vnd.wolfram.nb (accuracy 100) So, gvfs is getting it wrong. mimetype and kmimetypefinder are getting it right. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Meant to mention, this is with gvfs-1.26.2-1.fc23.x86_64
Reassigning to glib, as I think this must be a bug in the weight handling in xdgmimecache.c
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
