git svn rebase index file open failed : Invalid argument

Question

I use git-svn on windows for the first time , git svn rebase show error:

fatal: index file open failed: Invalid argument

Why it happened and how can i fix it ?

Thanks.

Answer 1

If you are using msysgit on windows, there is a regression on msysgit1.8.4 for git-svn .
It seems to appear when executed in a CMD, not in a bash shell, so you can try that same command in a shell.

Or you can SubGit , which is much more complete and robust tool for transitionning from svn to git repo. Listen to his author at GitMinutes #22 .

The regression is in progress to be fixed (currently -- October 2013 -- in the ' next ' branch of the git repo ) Bas Bossink confirms in the comments :

I just verified that it is fixed in git 1.8.5.2.msysgit.0

See commit 7fbd42 , by jiangxin :

Tvangeste found that the " relative_path " function could not work properly on Windows if "in" and "prefix" have DOS drive prefix (such as "C:/windows"). ( $gmane/234434 )

Eg, When execute: test-path-utils , relative_path "C:/a/b" "D:/x/y" should return " C:/a/b ", but returns " ../../C:/a/b ", which is wrong.

So make relative_path honor DOS drive prefix.

I was seeing this problem when using --separate-git-dir with working directory and git directory on separate drives (git on a network drive in my case). As a workaround I've confirmed that you can use mklink (run as admin) to map the target drive: mklink /d "C:\\temp\\my-git-dir" "D:\\my-git-repo\\"

Then something like the following will produce a viable repo and working dir. git clone --no-hardlinks repo_url --separate-git-dir=D:/my-git-repo C:/temp/my-working-dir
