Make go packages from subdirectories on gitea instances installable with "go get"

[jcgruenhage]

Currently, you can't fetch go projects from gitea, without the .git extension. This causes the binaries to have this ugly .git extension too and prevents people from fetching projects from subdirectories.

Since this affects me more than I thought, I've decided to start looking into it. I've found that the header file in the base template folder already contains a meta tag for that, but that doesn't work, because somehow {{.GoGetImport}} doesn't start with the domain, but with localhost instead.

@jcgruenhage any news?

I test go get git.lunny.info/lunny/tango. There is no problem. I found that you have to add DOMAIN = <your domain> on your custom/conf/app.ini before SSH_DOMAIN to let it work.

I've changed the title. If the root directory is the go project you want to get, there is no problem, but if you want to get something in a subdirectory, that does not work, since the 404 page does not contain the appropriate meta tags.

Works:

go get git.host.tld/user/repo

Doesn't work:

go get git.host.tld/user/repo/subdir

Workaround:

Clone the repo into $GOPATH/src/git.host.tld/user/repo first.

#1518 should fix go get git.host.tld/user/repo/subdir have you tried that?

[jcgruenhage]

I am not sure why, but it seems to work.. I didn't think that that HTTP func was actually called when serving a 404..
