commit hangs [message #1726935]

I've been fighting this for a while, working around it by committing from the command line: When I commit (even a single small file) from Eclipse it hangs at 0% indefinitely and I have to kill Eclipse. This is on Windows. I am using Eclipse 4.5.2 and egit 4.2.0.201601211800-r but this has been going on since at least Eclipse 4.5.1 and egit 4.1.1

Any ideas on how I can further diagnose the problem?

Thanks.

Do you have pre-commit hook in your repository which may block commit ?
Create a couple of thread dumps and check them for dead locks and other suspicious things.

I took an Eclipse thread dump with jvisualvm, and it looks like it must be a problem with interference from AV software:

   java.lang.Thread.State: RUNNABLE
	at java.io.WinNTFileSystem.list(Native Method)
	at java.io.File.list(File.java:1116)
	at java.io.File.listFiles(File.java:1201)

Thanks for the tip!

Actually the problem is not AV but rather a circular link definition, e.g.

bash$ pwd
/c/Users/dwyttenb
bash$ find . -type l -ls
281474976832258      0 lrwxrwxrwx   1  dwyttenb 1049089        31 Jul 31  2014 ./AppData/Local/Application\ Data -> /c/Users/dwyttenb/AppData/Local

Code that demonstrates the issue at https://github.com/wytten/List-Files
