12.0.3 RC2: merged-login.js temporarily (>multiple hours) empty after upgrade, leaving login button disabled

[Fiech]

Steps to reproduce

1. Update from 12.0.2 to 12.0.3 RC2
2. Navigate to login page and try to use login/use login button

Expected behaviour

Login works as expected (either get into nextcloud or get to 2FA-Screen)

Actual behaviour

Button/Enter-key not responsive. After multiple hours (at least 4-5h later, I rechecked not until 2 days later when I came around to writing this bug report) the login works as expected.

Background information

I tracked down the problem to the fact that the JavaScript file /js/core/merged-login.js stayed empty for at least 4-5h or so. Everything else worked and I also could log in if I manuall remove the disabled-attribute in the dom-inspector. My hotfix was to remove the disabled-attribute in the template file.

Thing is: merged-share-backend.json (or /js/core/merged-share-backend.js) and merged-template-prepend.json (or /js/core/merged-template-prepend.js) worked just fine.

I compared the checksum of the involved files in merged-login.js with another, older NC installation, there is no difference.

I previously opened a thread in the support forum.

I guess it's some kind of caching issue... Idk, why it only affected this one file...

I did not look into detail but I had this issue as well when upgrading:

Some of the things I checked:

• The file was present in the appdata_ dir
• The file contained data
• For some reason the file was empty when fetching

I have not been able to reproduce on my test env unfortunatly

[skjnldsv]

This is strange since the retrieving of the file is pretty simple code - wise... :/
Do you get a http code 200? Could you try wget the file?

[Fiech]

Unfortunately, I cannot test this anymore, but back then I checked with the error console in chromium and firefox and there was no error fetching the file clientside. The file simply was empty. I also navigated to the file with both browsers (with and without 'v'-GET-Parameter) only getting displayed an empty file.

[rullzer]

@skjnldsv I did get a 200 then. But i also could not figure out what was exactly causing it.

[Fiech]

So, I upgraded to 12.0.3 just now without any problems...

[skjnldsv]

Very strange.. :/

[MorrisJobke]

We cannot reproduce this anymore :/ I will close this ticket. If this happens again, just state it here and we can look into it. I guess #7109 also helps to mitigate such stuff.
