@Hackwar please check, maybe the correct full tag should be already set in parseRule?

@Fedik Thanks for the discovery and fix. I was going to pass it as successful but then I discovered a really odd situation... let me explain...

This testing installation (which I recently re-installed) did NOT have the System Configuration setting:
Force HTTPS turned on... (Entire Site)

During testing I found that WITH your patch on and the dd('test'); text added to line 113, I could not turn the site to HTTPS... I would get:

HTTPS has not been enabled as it is not available on this server. HTTPS connection test failed with the following error: HTTPS version of the site returned an invalid HTTP status code.

I have tried this now 5 times so I doubt it's my testing method/process. I also have other test installations on the same domain in other sub-folders and none of them have an issue with Enabling/Disabling HTTPS...

Any ideas as this relates? is it important/worrysome or just because of the specific testing done for this PR?

Thanks.

@Fedik Yes good catch, this seems to fix the problem

(sorry for my question now but does that mean what I found is nothing to be concerned about, i.e. that I can validate your PR as is or am I waiting for an update from your to re-test and where I should not come across the same thing (HTTPS not being able to be turned on)?

Thanks for your patience - just trying to make sure @Fedik

[Fedik]

@exlemor yes it is tricky, the testing code dd('test'); will break any redirect,
I think what you get is kind of fine, but do no worry. We still be need review from @Hackwar

[brianteeman]

Do you know which pr introduced this bug? We should check everything in that pr

[Fedik]

it is from

• [6.0] Languagefilter: Refactoring of routing #43858

[Fedik]

Here still a question, should the full tag be already set in the parseRule method?
Hard to compare with old behavior.

I have tested it successfully...

That said, I also found this artifact/quirk discussed here:
#45947 (comment)

based on @Fedik's replies and comments and an upcoming future review by Hackwar, I will validate my test.

Do not set it RTC for now, I still need to check few things.

[Fedik]

Okay, should be good now,
I checked Joomla 5 does not set lang in to Uri for full tag, and I update the pr to work the same.

I have retested this successfully. Thanks @Fedik!

(the HTTPS quirk that I mentioned in my earlier test is still present if it matters).
