No wiki for migrated repo

[cracker0dks]

Hey,
I use the latest Dockerversion of Gogs and migrated a lot of repos successfully. But all of them have no wiki and are showing error 500 when I want to visit the wiki.
The Server log shows:
2016/10/21 03:02:24 [...routers/repo/wiki.go:54 renderWikiPage()] [E] GetBranchCommit: object does not exist [id: refs/heads/master, rel_path: ]

If I make a new test repo iside the gogs page, I can add a wiki as intended.

Is this my fault? How can I add a wiki to a migrated repo?

Thanks :)

PS: I dont want to migrate the wiki... I just want to be able to add a new one after code migration.

I have the same problem and it appears that the migrated wiki repositories do not have a master branch. (located next to the original repository in the gogs repositories folder)

When I run a git branch I do not see a master branch in the migrated repositories. Which is confirming what the error log states.

Since I only have empty wiki's my workaround was to delete the existing/migrated wiki repository and copy the one from the locally created test project which does have a master branch.

@512gbyte I had the same issue, you need to update your server's git version. I think it needs to run 2.7.1 or higher.

I was running 1.5* something, deleted the .git, created a new repo, pushed and every works as intended.

Hope this helps

git version is 2.7.4. this is running on aws (ubuntu-server-16.04)..

[y4my4my4m]

@512gbyte that's strange..I had the exact same error and problem as you and updating fixed it. Can you try upgrading it more? I'm currently running git 2.8^ . I'm sure you've tried already but just in case, since you mentioned you're migrating from previously existing gits,

1. In admin settings -> Rewrite all hooks.

2. Create a new repository from scratch, try creating a wiki.

I doubt No.2 will work but doesn't hurt to try ¯_(ツ)_/¯

thanks for reply!
i choose No.2 options, my wiki is not important but i just want to notice this case. 😄
i really satisfied 'gogs'!

[y4my4my4m]

@ghost so it worked?

Ok, I got an easy workaround for the 500 Error.
Go to the repo -> settings -> delete all wiki data
Then activate the wiki function again.
Now you can use the wiki without problem 👍

@cracker0dks where did you migrate from? Gogs tries to clone related wiki repository if exists, see https://github.com/gogits/gogs/blob/master/models/repo.go#L640-L650

[jxsl13]

Same issue, migrated from gitlab.com
cracker0dks' workaround works, for now :)
Hopefully migrated wikis will be either initialised or copied from e.g. github if it's a github project.

[unknwon]

Failed from gitlab.com because I think it always requires a password? I can migrate any public repo with wiki from GitHub without any problem.

[jxsl13]

I mean that even tho no wiki got migrated (btw. I had no wiki), you don't get the page to create a new wiki entry, but instead a 500 error page.

[unknwon]

@jxsl13 can you create an example on demo site? (500 on wiki after migration)

@unknwon https://try.gogs.io/jxsl13/info-a/wiki

[unknwon]

@jxsl13 Thanks! What is the source URL so I can perform clone on my machine?

[jxsl13]

was actually a private project on gitlab: made it public https://gitlab.com/jxsl13/Informatik-A

[unknwon]

I might know the problem: Gogs detected that there is a wiki, but failed to clone and didn't clean up the directory. Will check on that, thanks for the info!

[unknwon]

Patch has pushed to fix this issue, please test on develop branch or https://try.gogs.io.

Note the already broken ones still won't work, but newly migrate ones should work.
