This is a [issue from TortoiseGit](https://code.google.com/p/tortoisegit/issues/detail?id=2233). After doing some test, I report it here. The following is the testing information I have tested. ### Folder Structure ``` Test |-- myrepo | |-- bar.txt | |-- foo.txt | |-- myrepo.git |-- .git ``` Testing repository is [here](https://code.google.com/p/tortoisegit/issues/detail?id=2233#c2). ### Using different worktree Set the config file (in the .git folder) ``` [core] worktree = ../../myrepo ``` ### Test 1 - Git Bash ``` User@PC /d/Repo/myrepo.git (master) $ git --version git version 1.9.4.msysgit.0 User@PC /d/Repo/myrepo.git (master) $ git update-index --refresh fatal: Unable to write new index file ``` D:\Repo\myrepo.git\\**index.lock** is not deleted. ### Test 2 - Git 2.0.0 Copy testing repository into ```C:\msysgit\MyTest``` Execute```msys.bat``` ```$ vagrant up``` ```$ vagrant ssh``` ```vagrant@precise64:/vagrant/git$ cd /vagrant``` ```vagrant@precise64:/vagrant$ cd mytest/myrepo.git``` ``` vagrant@precise64:/vagrant/mytest/myrepo.git$ git --version git version 2.0.0 ``` ``` vagrant@precise64:/vagrant/mytest/myrepo.git$ git update-index --refresh fatal: Unable to write new index file ``` Also, **index.lock is not deleted.** ### Test 3 - gitdll of TortoiseGit (git version 1.9.0) Tracing the source code into **compat/mingw.c** line 289 : xutftowcs_canonical_path() get the value of var. wpathname ``` D:\Repo\myrepo\.git\index.lock ``` It should be ``` D:\Repo\myrepo.git\.git\index.lock ``` line 294 : _wunlink() try to delete the file.(```D:\Repo\myrepo\.git\index.lock```) line 295 : GetLastError() return 3(ERROR_PATH_NOT_FOUND) (Actually, there is no ```D:\Repo\myrepo\.git``` folder.) -- View this message in context: http://git.661346.n2.nabble.com/git-update-index-not-delete-lock-file-when-using-different-worktree-tp7615300.html Sent from the git mailing list archive at Nabble.com. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
