Description

I open pull request with multiple commits, then i open 5 new tabs in browser with each commit. Everything is ok. When i open the sixth tab and further they hang with message “Waiting for available socket…” until i close one of the previously opened tabs. It can be reproduced in any browser. What can this be connected to?

Also Reproducible

version: 1.12.1 proxy: apache 2.4 env: docker container

5-6 clicks and gitea hangs, but when I open a private window and login, gitea works and is accessible again.
Then I tried to reproduce this issue within a private window -> no chance
Its interesting that in the debugger inside a private window I can see connections to /user/events (See the curl cmd below) while navigating, but not within a regular browser tab
When doing the last click, no communications occur (Checked proxy access logs)

curl 'https://GITEA_HOST/user/events' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0' -H 'Accept: text/event-stream' -H 'Accept-Language: en-US,en;q=0.5' --compressed -H 'DNT: 1' -H 'Connection: keep-alive' -H 'Cookie: lang=en-US; i_like_gitea=33dxxxxxxxxx270; _csrf=zIz1_5HrJzMfqWC4XXXXXXXXXXXXXXXXXXXXXOTQyNw' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache'

Can anyone reproduce this on try?

It seems I do. Both in Firefox and in Chromium.

I just have to Login and from the Dashboard open multiple commits in tabs. If then I click on “View source” it will not load until I close enough(about 5 tabs are left open) tabs.

It seems to be about 5 tabs in each browser, as I could test Chromium while Firefox tabs were still open.

Same problem. But I could not reproduce this issue without a reverse proxy server (nginx in my case). By the way, in Firefox pages stop loading after five clicks on the site in one tab.

UPD: Using http2 in nginx solved the problem

Can confirm, opening any new tabs after 6 have loaded for me results in awaiting for socket. Hosting on Docker as well.
