sshfs hangs: culprit? __git_ps1 and bash completion

Weird one. Not sure who to report it to even. On my Fedora 17 development machine, I have the following in my ~/.bashrc

PS1='\u@\h:\w$(__git_ps1 " (%s)")\$ '

This makes a very nice bash shell with git status. Except, something odd happened when I tried to use sshfs. I could “ls” the newly mounted directory, but I couldn’t “cd” into it. It just hung. Dead in the water, control-c, control-z, kill and kill -9, nothing. WIth some sshfs debug options turned on, I saw that it was failing like this. (Whatever it means)

unique: 535, opcode: GETATTR (3), nodeid: 1, insize: 56
getattr /
   unique: 535, success, outsize: 120
unique: 536, opcode: ACCESS (34), nodeid: 1, insize: 48
   unique: 536, error: -38 (Function not implemented), outsize: 16
unique: 537, opcode: LOOKUP (1), nodeid: 1, insize: 45
LOOKUP /.git
getattr /.git
[00343] STAT

For reference, my sshfs command line is like so: karlp@pojak:~/src$ sshfs root@ oroot -odebug,sshfs_debug,loglevel=debug -o no_remote_lock -o follow_symlinks -o workaround=rename But I tried with a lot less options and a lot more too.

The console hangs like this:

karlp@pojak:~/src$ ls oroot/
bin  etc  lost+found  overlay  rme_post_fresh_install.log  root  sys  usr  www
dev  lib  mnt         proc     rom                         sbin  tmp  var
karlp@pojak:~/src$ cd oroot


Now, seeing that getattr /.git there made me think, and indeed, disabling the git bash extension and using a new shell works just fine. It makes no sense, but it works ok.

Even “git status” hangs, so this really isn’t fixed at all. :(
