I had a problem with RhodeCode 1.4.0b which was installed on 2012-08-15. I'll try to reccount the steps that led me to the problem.
I wanted to import a Git repository into RhodeCode as /sw/ger/v3, i.e., /sw/ger would be repository groups and /sw/ger/v3 would be the repository.
By mistake, I created /sw/ger/v3 as directories under RC's repository store and moved the git repository to /sw/ger/v3/git.
Then I performed a repository scan as RC's admin user.
Then I realised the error and decided to try again.
I deleted the repository /sw/ger/v3/git.
I removed the directory /sw/ger/v3 by hand. (Stupid mistake, I know.)
I moved the repository to /sw/ger/v3, as it should have been.
I performed another repository scan.
Then RC got confused, because it now had a repository called /sw/ger/v3 and a repository group by the same name. I became weird when I tried to navigate to the repository.
I tried several things to resolve it to no avail. I ended up doing the following in order to get it back into shape:
I deleted the repository /sw/ger/v3.
I deleted the repository group /sw/ger/v3.
I moved once again the external repository to /sw/ger/v3.
Performed another repository scan.
Now everything seems ok.
Obviously I shouldn't have removed the directory /sw/ger/v3 by hand. But perhaps, RC could be a little more cautious and verify, during the scan, if there are some clashes like the one i got in to.
I want to say that this was the only issue I got when I tried to import almost 100 Git repositories into RhodeCode. I was very much impressed by its overall robustness. Thank you very much for such a great work.
