POcreating a temporary file in python with FUSE

Body
copied!<p>I am trying to write a program using python-fuse, but I can't get file writing down. my file_class looks like this</p> <pre><code>class FuseFile(object): def __init__(self, path, flags, *mode): debug(path) #debug(mode); self.file = tempfile.TemporaryFile(*mode); self.fd = self.file.fileno() self.path = path def write(self, buf, offset): head, tail = os.path.split(self.path) self.file.seek(offset); self.file.write(buf); return len(buf) def read(self, length, offset): file = apiCall("readfile",{"file":self.path}).read(); slen = len(file) if length < slen: if offset + size > slen: size = slen - offset buf = file[offset:offset+size] else: buf = '' return file # I don't know if this buff stuff is necesarry... def ftruncate(self, len): self.file.truncate(len); def release(self, flags): self.file.close() def flush(self): self._fflush() def fsync(self, isfsyncfile): self._fflush() if isfsyncfile and hasattr(os, 'fdatasync'): os.fdatasync(self.fd) else: os.fsync(self.fd) def _fflush(self): if 'w' in self.file.mode or 'a' in self.file.mode: self.file.flush() </code></pre> <p>but when I try and edit the file in a editor like VIM I get this: </p> <pre><code>"mnt/stuff.txt" E514: write error (file system full?) WARNING: Original file may be lost or damaged don't quit the editor until the file is successfully written! </code></pre> <p><code>[EDIT]</code> I found the problem, I didn't have a open method, but even so, I eventually took out the file_class to implement the methods in the main FUSE class, because that seems to work better</p>
