SUMMARY


STEPS TO REPRODUCE
1.  start okular.
2. open a pdf file with a link.
3. click on the link

OBSERVED RESULT
the html page is downloaded to a file (~/.cache/kioexec/krun/304260_0/name_of_the_link_page), and a pop up appears saying " Select the program you want to use to open file name_of_the_link_page". and upon selecting chrome it opens the file in chrome and all i can see then is raw html code in the browser, and the address bar pointing somewhere on my computer (local file)

EXPECTED RESULT
click link > open the link in the browser.

Comment 1 Alejandro Villar 2024-06-07 09:24:06 UTC

In my case (Ubuntu 24.04 LTS with okular 4:23.08.5-0ubuntu5), the URLs are first queried and then the default text/html handler is opened (Kate on my machine), instead of being opened directly by Firefox (my default browser).

If I change the file association for text/html to Firefox, Okular first fetches the URL and then passes it (the URL, not the fetched file) to Firefox, so in essence the resourced is retrieved twice (confirmed with Wireshark).

I think this behavior is due to the following change, in which KRun is replaced with KIO::OpenUrlJob: https://github.com/KDE/okular/commit/1b479dfb7b

Not a QT or KDE expert, but could this maybe be replaced with QDesktopServices::openUrl()?

Comment 2 Alejandro Villar 2024-06-07 10:10:11 UTC

I can confirm that after changing the URL handling methods to QDesktopServices::openUrl(), links are opened directly in Firefox.

Note: the sources for my version didn't have the KRun->KIO::OpenUrlJob change yet, so maybe something changed in KRun?
