mailbox locks, part2
Inspired by Greg A Woods comments, I went ahead and built a bit more
generic mechanism to handle all locking styles and things. (It did
also clean up the code quite radically...)
ZENV variable MBOXLOCKS defines which locks are to be acquired,
and in what order:
. UNIX dot-lock (At Solaris/SysVr4(?): maillock() )
L lockf() -locks
F flock() -locks
Default for the MBOXLOCKS value (and thus the sequence) is: "."
By looking at the code, I do think that at the moment there are no
locks when appending to non-mailbox files.
I wonder, should there be a separate FILELOCKS variable with default
depending wether or not flock() is usable: "F" or "L".
Or perhaps MBOXLOCKS should be ".F" or ".L" in every case ?
(New Linuxes seriously dislike same program doing lockf() and flock()
Hmm.. there is still that mailbox double-creation problem,
that our correspondent from Argentina noticed. Well, tomorrow
is a new day :) Good night folks.
