Small files (962 bytes) get transferred as 0 byte files

[razeh]

If I transfer a 962 byte file, the file is created on the server, but it is 0 size:

ls -l foo 
-rwxr-xr-x 1 razeh btt 962 Apr  1 15:39 foo*

ls -l foo
-rw------- 1 razeh btt 0 Apr  1 15:40 foo

The log on the server is:

After looking at this with strace, and adding some logging, I believe this is caused by accessing the file with fdopen and open. Removing the FILE pointer, and using stat to get the file size, fixes the problem for me.
