[9fans] imap4d and upas/fs

[Gabriel Diaz]

Hello

is there any way of serving imaps without running upas/fs for each
mail box accessed on the server?

i'm running out of memory.

I saw that upas/fs is called from auth.c of imap4d with -np so, i
suppose it ill not use much memory (if i call it by hand it eats
268K), but when imap4d execs it, i can't see any command line options
for fs with ps -a, but i can see high memory usage (depending on the
box i open).

is upas/fs executed from other places i don't see? is anyone seeing
this or i missconfigured something?

thanks

unfortunately, this is the expected behavior.
the only current solution is to have a smaller mailbox.

hello

oh, so upas/fs is the one which transforms the mailbox format to what
imap clients expect, i thought that would be done by the imap4d. . .

thanks

not exactly.  upas/fs turns its inport fmt into a directory containing
1 directory per message.  this is the standard format that programs
like imap4d, nedmail and acme Mail can understand.  imap4d
upas/fs's filesystem into imap4 commands.  inport fmt can be an
mbox, imap4 or pop3.  i've added support for mail directories
somewhat similar to mdir format.  unfortunately that's not quite
finished.

p9p upas/fs can only read imap4 and the directory format is somewhat
different.

Russ has rewritten p9p's upas/fs to address this problem. p9's
upas/fs could be patched accordingly IIRC. Russ will know more...

p9p upas/fs is quite a different program.  it does not handle
locally-stored mail.
