[fuse-devel] setattr missing when writing?

[Reuben H. <reu...@gm...>]

Hi,

I'm attempting to create a trivial in memory filesystem (simply to
learn fuse), I can copy a file into my filesystem, but I can't write
to it after that...

reuben@archive:~/src/ezfs/test$ cp ../ezfs.c .
reuben@archive:~/src/ezfs/test$ ls -la
total 4
drwxr-xr-x 2 root   root      0 1969-12-31 16:00 .
drwxr-xr-x 6 reuben reuben 4096 2011-05-26 08:47 ..
-rw-r--r-- 1 reuben reuben 3427 1969-12-31 16:00 ezfs.c
reuben@archive:~/src/ezfs/test$ echo test > ezfs.c
bash: ezfs.c: Function not implemented

My debug output says...

unique: 131, opcode: LOOKUP (1), nodeid: 1, insize: 47
LOOKUP /ezfs.c
getattr /ezfs.c
   NODEID: 2
   unique: 131, success, outsize: 144

   open[0] flags: 0x8001 /ezfs.c

unique: 134, opcode: RELEASE (18), nodeid: 2, insize: 64
   unique: 134, success, outsize: 16

There's no setattr in fuse_operations?  What am I'm missing here?

Thanks in advance,
Reuben
