Created attachment 1242294 [details] add midori and qutebrowser to the BROWSER list Description of problem: On systems where no well-known browser like firefox is installed xdg-open fails to open an http url via midori or qutebrowser. Version-Release number of selected component (if applicable): xdg-utils-1.1.1-4.fc25.noarch How reproducible: always Steps to Reproduce: 1. install Fedora 25 with no web-browser except midori and/or qutebrowser - e.g. install the Fedora 25 LXDE spin 2. $ xdg-open http://example.org/ 3. Actual results: /usr/bin/xdg-open: line 805: x-www-browser: command not found /usr/bin/xdg-open: line 805: firefox: command not found /usr/bin/xdg-open: line 805: iceweasel: command not found [..] /usr/bin/xdg-open: line 805: lynx: command not found /usr/bin/xdg-open: line 805: w3m: command not found xdg-open: no method available for opening 'http://example.org/' Expected results: midori/qutebrowser is installed -> xdg-open opens the url with midori/browser Additional info: Both midori and qutebrowser are available via the fedora package repository. Midori comes pre-installed with Fedora LXDE spin.
Really though, the last fallback to check a static list of browsers should almost never happen. do neither midori or quitebrowser support x-scheme-handler/http mimetype? checking midori.desktop and qutebrowser.desktop both properly include: x-scheme-handler/http;x-scheme-handler/https So looks like the real failure is the function call: open_generic_xdg_x_scheme_handler "$1" isn't working as expected here.
Looking at the execution trace of the xdg-open shell script I see this: It calls `xdg-mime query default x-scheme-handler/http` which returns `firefox.desktop`. This value comes from `/usr/share/applications/mimeapps.list`, cf. $ grep firefox /usr/share/applications/mimeapps.list text/html=firefox.desktop application/xhtml+xml=firefox.desktop x-scheme-handler/http=firefox.desktop x-scheme-handler/https=firefox.desktop This file is part of shared-mime-info-1.8-1.fc25.x86_64. Thus, xdg-open sets the local `default` variable to `firefox.desktop` inside `open_generic_xdg_mime` where it is supplied as parameter to `search_desktop_file` - which is repeatedly called for different xdg directories. And that's it - the default value is the only value that is searched for. Does this work as designed? It looks like xdg-mime would do a search over the *.desktop files only as fallback, i.e. if there is no default in /usr/share/applications/mimeapps.list.
Thanks, that analysis makes sense, and I agree it should be improved to better handle the case when the default is not present.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. 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 '25'. 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 25 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 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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.
