On my windows 10 machine via cmder terminal, every single important git command is now hanging completely. I haven't waited more than 5 minutes to cancel.

For example, git pull will just hang indefinitely. I will then press ctrl+c, and when I run git status (no problem with this) I'll see files being updated. However, no commit is shown in the git log.

git checkout is also hanging, nothing is happening.

I have no idea how to fix this. I have run git prune, git gc, and git fsck --unreachable. Nothing showed up when I ran git fsck --unreachable or git fsck at all, and when I ran git prune it just completed but fixed nothing. Git gc also completed but fixed nothing.

EDIT: ran strace git checkout <branch>

λ strace git checkout develop

this isn't the full output. While I was editing this question some threads exited. so it's hanging on the thread creation?

EDIT: This definitely is not a cmder issue either. I just ran git bash and am running into the same issue. I did GIT_TRACE=1 git checkout <branch> and it produced nothing, only this

$ GIT_TRACE=1 git checkout develop
20:31:33.554953 exec-cmd.c:236          trace: resolved executable dir: C:/Program Files/Git/mingw64/bin
20:31:33.559955 git.c:419               trace: built-in: git checkout develop

EDIT: The issue was resolved by restarting my computer. I am not sure why that fixed it or what caused the issue in the first place. Hopefully someone will find an explanation.

  • Git has verbose options, have you tried them? – mason Apr 28 '19 at 03:02
  • yeah, checkout doesn't have a verbose option – Jeremy Fisher Apr 28 '19 at 03:03
  • `strace` always exists (on Linux; on MacOS or Solaris, see `dtruss`); to track syscalls on Linux with less overhead, see also [sysdig](https://sysdig.com/). Watching the actual filesystem or network operations will let you know what's hanging. – Charles Duffy Apr 28 '19 at 03:06
  • ran it for git checkout, please see output above – Jeremy Fisher Apr 28 '19 at 03:10
  • Use the `-f` argument to `strace` to follow actions done in subprocesses. Though on Windows you may need a different set of tools built for the platform; strace proper is very Linux-specific -- I'm astonished Cygwin (or whatever you're using) provides the command at all. – Charles Duffy Apr 28 '19 at 03:48
  • So I restarted my computer and it seems to be working fine now. However I think there still needs to be an explanation for this random behavior. – Jeremy Fisher Apr 28 '19 at 04:02

    @JeremyFisher: File locking. You restarted the computer and the problem went away. You will never get a good explanation now. – Joshua Apr 28 '19 at 18:35
  • I don't think file locking is the answer because I closed my editor and I still had the same problem. – Jeremy Fisher Apr 29 '19 at 00:39

The issue was resolved by restarting my PC. I am not sure why that fixed it or what caused the problem in the first place. Hopefully someone will find a good explanation.

Try first to execute the same commands, still in CmdEr (but also, for testing in a regular CMD) after having set a simplified PATH:

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%

See if the issue persists then.
