Incomplete data: Delta source ended unexpectedly while git svn fetch

Question

I have cloned my svn repo into git and everyday i am doing git svn fetch (i only do changes in SVN) but i am planning to move to git and i keep the git repo in sync for the day since the svn clone tooke me 2 weeks (yeah it's a big repo).

Anyway the git svn fetch has worked fine every day until 2 days ago where i now get

Incomplete data: Delta source ended unexpectedly at /usr/lib/perl5/site_perl/Git/SVN/Ra.pm line 290

at a specific revision. I tried the different suggestions online about git svn reset and going back some revisions and i went about 20 revisions back with no luck. I also tried to run :

git config --get core.autocrlf

which gave true.

I know that the svn repo is working good, i have no issues doing svn up.

Any ideas how i can get back on track to sync again ? I am stuck without ideas what to try.

I might reveal one issue. I don't recall but before running the issue i might have had a disk full on the disk where the repo is when i tried the fetch. Maybe that destroyed something ?

Hi @dbrasco, did you solve the problem? If yes, please provide an answer. I have the same problem. — boskicthebrain

Make sure there are no additional git/perl processes running (which could create the index.lock file and mess up the current fetch). Kill'em all.
Delete the ...\my_repository.git\.git\svn\refs\remotes\trunk\index.lock file
git svn reset -r SomeSVNRevisionNumberBeforeTheProblematicOne
git svn fetch

Fetch should continue from the SomeSVNRevisionNumberBeforeTheProblematicOne.

The most probable reason why this happened is concurrency between two git instances running simultaneously on the same repository.

Using --ignore-paths sometimes helps, so the steps are:

git svn reset -r <svn-version-before-error>
git svn fetch --ignore-paths=/branches/badbranch

I resolved similar problem using -r param. My case was as follow:

I created /branches/dev branch in SVN at particular revision, eg 1000 and started using it
all previous revision were made to /trunk
I started master branch migration with git svn clone, which got all svn /trunk to git master
then I've added another fetch config for my svn development branch and resumed the svn fetch

# .git/config
[svn-remote "svn"]
    url = http://some-repo/path
    fetch = /trunk:refs/remotes/trunk
    fetch = branches/dev:refs/remotes/dev

git svn fetch complained at revision 999, which belong to /trunk and has been already migrated to git master (Incomplete data: Delta source ended unexpectedly at /usr/lib/perl5/site_perl/Git/SVN/Ra.pm line 312)
notice error refers to line 312, which might be related to different problem than line 290 referred in this ticket?
then I run git svn fetch -r 1000:HEAD, which allowed me to migrate all revisions of /branches/dev excluding revisions before creating /branches/dev
