mailbox locks
Hello,
The mailbox locks are not quite so simple as I had
thought. Autoconfiguring will detect system locking
capabilities -- with an assumption that having locking
system calls (library functions), they are usable.
Some experiences with autoconfigured Linux seems to
indicate that only "dotlock" method should be used,
or that the order of locks used now is wrong.
I have been thinking of building a runtime configration
mechanism for choosing locks, and their orders, but
what would be suitable method ? Storing the sequence
at the /etc/zmailer.conf environment variables ?
Oh yes, the hashed spool subdirectories mechanism for
the scheduler has proved to be quite interesting.
I am not so sure if it has speeded up the system, but
at least directory accesses have now smalled subdirs
to search.
