Hi folks, I'm having a major problem with sshfs. I'm using macfuse
2.0.3.2 along with the static sshfs from svn (for leopard).
I see the following behavior:
$ echo -n 'abcdefghijklmnopqrstuvwxyz' > test
$ cp test /mnt/point/
$ echo -n '1234567890' > test
$ cp test /mnt/point/
$ cat test
1234567890
$ cat /mnt/point/test
1234567890klmnopqrstuvwxyz
I've checked, the cp command does an open and write(2)s the correct #
of bytes (10 in this case) to /mnt/point/test. However sshfs shows
this in the logs:

It gets (opens for reading, and then reads) the remote file
('abc...xyz'), then writes 26 bytes (not 10)!
This makes sshfs unusable for me, and I haven't been able to get a
version that I compiled to run successfully (It gives Input/Output
errors), so I can't debug it more. I suspect its some kind of problem
with caching, but happens even when i specify cache=no
The interesting thing is that sshfs on linux works correctly. Does
anyone have any insight into this?
yours,
Bobby
