Sync with Subversion - "Username: Use of uninitialized value $username in chomp"

Manuel Fegerl1

Hello.

I got a problem when trying to sync with my subversion Server. The full log:

git svn rebase
Authentication realm: <http://svn> DTI SVN
Password for 'mfegerl':
Authentication realm: <http://svn> DTI SVN
Username: Use of uninitialized value $username in chomp at /Applications/SourceTree.app/Contents/Resources/git_local/libexec/git-core/git-svn line 4035.
error: git-svn died of signal 11
Completed with errors, see above

Cannot find anything in google (except a old link that does not work anymore)

Having worked through this issue myself, I finally got past the error. Hopefully this might help someone:

Note I am using a Mac (Mountain Lion) here. When you clone initially from e.g. google codeproject subversion repository via https, no password is required. So far so good. To use a codeproject subversion repository via Sourcetree, you must point to it using Sourcetree which then pulls the entire repo down and converts it to git format. If you want to push, sourcetree knows to use the git-svn technology to translate back into subversion format.

However for me, when I did push, sourcetree screwed up and failed, because a password is required, and somehow sourcetree doesn’t bother to prompt you for it. Same goes for the username being used - sourcetree uses your mac username rather than your codeproject username blah.

Even going into the sourcetree / repository settings / edit config (which is really .git/config) and adding

[svn]

username = blah

password = 123123123

helped a bit re username but not really re the password.

The solution for me was to straighten out my svn authentication from the terminal - totally independently of sourcetree. So I did a normal https svn checkout of the codeproject repo and did something that required a password, like doing an add/commit from the terminal. This will prompt whether to save the certificate and prompt you for username and password - all of which gets stored in ~/.subversion. You may also get a prompt (from perl?) asking to store a password in the mac keychain, which is ok.

Then go back to the other working copy created by sourcetree (the subversion to local git directory version) and pushing with sourcetree will now work.

If you want to be really clean or already have wrong subversion information (e.g. you changed your password in the repo but subversion has recorded the old one locally), you can delete the bits in ~/.subversion relating to your code repository. This is not as scary as it seems, if you

ls -R ~/.subversion

you will only see a few files, all of which are easily recreated when you answer questions from the terminal when running svn commands.

E.g.

the file in svn.simple dir is the username/password - you can delete this file e.g. 6cd...

the file in svn.ssl.server is the ssl certificate - you can delete this file e.g. f7bcb...

Incidentally you can also safely delete entries in the mac keychain app relating to your code repository - search for parts of your unique repository name and the relevant keychain entry should appear - if it exists. If you delete it, it will just get recreated as necessary.

Anyway the point it is, after clearing these areas and running a commit using svn command line (and answering the prompts) sourcetree will then operate correctly, because the command line subversion is working and authenticating ok.

This one is actually covered in the KB: http://confluence.atlassian.com/display/SOURCETREEKB/Error+Message+%27Username+Use+of+uninitialized+value+username+in+chomp%27+Due+to+System+Git

Thanks to your answer, unfortunately this happens to me with the embedded GIT as well.

Another thing that may avoid it is including your svn username in the URL, as in https://user@host.com/path/to/repo.

I'm also running into this problem with an SVN repo.

I've tried:

system git vs embedded git
username in URL vs not in URL
keychain entry vs no keychain entry

I always get the same result:

git -c core.quotepath=false svn rebase 
Current branch master is up to date.


git -c core.quotepath=false svn dcommit 
Committing to svn://server:3693/project/trunk ...
Authentication realm: <svn://server:3693> Development Team
Password for 'liam.jones': 
Authentication realm: <svn://server:3693> Development Team
Username: Use of uninitialized value $username in chomp at /Applications/SourceTree.app/Contents/Resources/git_local/libexec/git-core/git-svn line 4410.
error: git-svn died of signal 11
Completed with errors, see above

Interestingly it's asking for a 'liam.jones' password even if I've remove the username from the URL in the config file and removed the server entry from the keychain. Not sure where it's still finding it...

I saw in another answer that I should get a prompt box/sheet to fill in the password if git is asked for one but this doesn't seem to happen. If I manually run the dcommit from the terminal (and enter the password when prompted) then it all works fine.

Any other ideas on a fix for this Steve?

I have the exact same problem but my repo is hosted on https. I'm exactly at the point where Liam gave up and I really don't want to have to use SVN directly (sob)
