Ah, I've found what you were meaning...
this is from PosixFilesystem.py (ZODB implementation):
import os
from posix import fsync
....
def sync_directory(self,dir):
if self.use_sync:
p = os.path.join(self.dirname,dir)
# Use os.open here because, mysteriously, it performs better
# than fopen on linux 2.4.18, reiserfs, glibc 2.2.4
f = os.open(p,os.O_RDONLY)
# Should we worry about EINTR ?
try:
fsync(f)
finally:
os.close(f)
def write_file(self,filename,content):
fullname = os.path.join(self.dirname,filename)
f = os.open(fullname,os.O_CREAT|os.O_RDWR|os.O_TRUNC,0640)
# Should we worry about EINTR ?
try:
os.write(f,content)
if self.use_sync:
fsync(f)
finally:
os.close(f)
