Method Details

__init__(self, dir)
(Constructor)

dir - the directory for the file

Overrides:
SCons.SConsign.Dir.__init__

write(self, sync=1)

Write the .sconsign file to disk.

Try to write to a temporary file first, and rename it if we succeed. If we can't write to the temporary file, it's probably because the directory isn't writable (and if so, how did we build anything in this directory, anyway?), so try to write directly to the .sconsign file as a backup. If we can't rename, try to copy the temporary contents back to the .sconsign file. Either way, always try to remove the temporary file at the end.
