It would be nice to get a final Ack before moving it to 'master'. -- >8 -- From: Petr Baudis Win32 does not allow renaming read-only files (at least on a Samba share), making push into a local directory to fail. Thus, defer the chmod() call in index-pack.c:final() only after move_temp_to_file() was called. Signed-off-by: Petr Baudis Signed-off-by: Shawn O.
