Description bastimeyer123 2022-04-25 08:29:28 UTC 
SUMMARY
This was introduced with the recent upgrade of Konsole to 22.04.0. Konsole 21.12.3 was working fine.

It now fails to parse URLs which include a port number. When pressing CTRL and clicking the link, it only matches the URL until the first colon character, leaving out the rest of the URL, namely the port number, as well as anything that comes afterwards, aka. path, query and hash.

STEPS TO REPRODUCE
1. http://localhost
2. http://localhost/foo
3. http://127.0.0.1/foo
4. http://localhost:8888
5. http://localhost:8888/foo
6. http://127.0.0.1:8888/foo
7. http://[2a00:1450:4001:829::200e]/
8. http://[2a00:1450:4001:829::200e]:80/

OBSERVED RESULT
1-3 work
4-6 don't work
7-8 also don't work, but I'm not sure if this was working previously

SOFTWARE/OS VERSIONS
Linux: 5.17.4
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.93.0
Qt Version: 5.15.3

ADDITIONAL INFORMATION
After searching for recent commits in Konsole's git repo in regards to URL parsing, I found these changes which added some distinctions between local file paths and URLs. Maybe it's related to the issue, but I am not sure, as I'm not familiar with Konsole's code at all.

Comment 1 bastimeyer123 2022-04-26 09:44:42 UTC 
URLs with username:password fail too, btw:
http://username:password@localhost/
Comment 2 ninjalj 2022-04-30 18:08:56 UTC 
The offending commit would be https://invent.kde.org/utilities/konsole/-/commit/1ee8c64b5189d9e32ae9660308b2edc0f35ea6f0

As to what the proper regex should be, the syntax for URIs is specified at https://datatracker.ietf.org/doc/html/rfc3986#appendix-A, with augmented BNF rules as defined in https://datatracker.ietf.org/doc/html/rfc2234
Comment 3 Ahmad Samir 2022-05-01 17:50:28 UTC 
I think 7 and 8 aren't that common (and it would complicate the regular expression used even more), so we can hopefully skip those ones.

I've tried my hand at implementing rfc3986 (thanks for the link :)) at https://invent.kde.org/utilities/konsole/-/merge_requests/646
not 100% compliant, but close enough.

In Bug 453364  I reported issue where in url is present comma. And this case has not been mentioned here.

The change in https://invent.kde.org/utilities/konsole/-/merge_requests/646 fixes the url-with-comma case too.
