[Mod-pubsub-developer] How to keep kn_events small. Plus, bug in mod_pubsub 0.5 distribution.

[Adam R. <Ad...@Kn...>]

Hi Yoz,

Thanks for finding the bug in the documentation; I have checked in a new =
INSTALL that walks people through running the Makefile to create =
pubsub.js and kn_events.  This will be bundled with the next tarball =
when we get around to making the next tarball.

Thanks for playing -- I think that's what we're all doing at =
mod-pubsub-developer!  Please do let us know if you're doing anything =
interesting.

As for questions, please ask the list so in case I'm busy someone else =
can answer.

As for the question of how to keep kn_events small, I have three =
techniques:

   1. Publish events with kn_expires header set to a low value.  The =
disadvantage to this technique is that the Perl pubsub server uses "lazy =
evaluation" in determining when to remove things, so it may not remove =
things as quickly as desired.

   2. Use the Python pubsub server instead.  Unfortunately, we don't =
have it working with the JavaScript applications yet, so this technique =
might take a while.

   3. Manually delete files or directories within kn_events.  This can =
be automated.  This is the technique I most often use.

Keep asking questions, please... it's the only way we're gonna make the =
system better...

Thanks,
   Adam

Ah - I didn't know that. I did it by hand.
Actually, the INSTALL file doesn't mention the Makefile.

Don't have one! It's okay, I'm mainly playing, though I have an idea for =

a chat client that PS would be good for. I'll let you know if it gets=20
anywhere interesting (though I'll probably be plaguing you with dev=20
questions before then)

Actually, here's my first dev question: what's the best way of stopping=20
my kn_events dir from getting massive? Do the files in it get physically =

removed in accordance with the expiry dates on the messages?
