So, in my recent experience building Po:Co:DBIAgent, I had to go thru some
really annoying chicanery to sucessfully pass a Storable record via a

a Network Newline(tm), eg "\r\n" because it turns out Storable embeds \n in

Based on conversations earlier on this list, I've built a DBI query agent
that runs in its own session and fires off a P::Wheel::Run to handle
queries. It works for UPDATE/DELETE as well as SELECTs.
However,

Does anybody know of a way to run a non-blocking DBI query? Non-portable is
ok with me, if it works with Oracle! :-)
But seriously, do we know about how to:

I'm interested in POE developers' comments about state management. Possibly
my ideas about implementation are on a different track than others', but I
found that in order to make my app 'POE-ized', I took what was essentially a
set of related (by concept) actions, and put two states for each in m

OK, I don't have alot of time, so I don't have lots of time to give a
step-by-step rundown. But I think the code is pretty self-explanatory, and
I don't mind answering questions later.

I'm curious,
should I be using C in my program(s)?
I can't find any specifics on yes or no, only that POE supports it. From
what I've gleaned about POE's operation, the most complex part of it is
state management/context switching. Since Event (task switching, async
looping) is written in C, do
In trying to make my app as long-lived and stable as possible, I've come up
against a snag:
In the even that my program fails, even when wrapped in an eval loop,
when I try to re-start things, I find that there are existing sessions in
memory, my previous incarnations of POE::Component::Server::TC
So I've got my project running, and naturally some tuning and bugfixing is
in order.
All of the changes are happening in my DBFetch module. Little modifications
as to what gets incremented where, in the local heap.
But alla sudden, my HTML reports are CRASHING the program!?!

It seems to me that you are making the problem more complex than it needs to
be.
If you want to execute a CGI script, one time, then you could simply cron
the following call (using Perl's LWP)
GET http://
So, I was running my server project under test load with 0.1204 (created w/
another POE server/session pair in about 15 minutes... POE is SOOO EASY!)
and I saw a little weirdness that well, made my stomach turn:
It would serve, say, the first hundred or so requests in a very reasonable
amount of
OK, for starters let me say that I'm getting all of this working on a
largely monkey-see, monkey-do basis... the stuff in /samples was invaluable
for getting started, but somehow I doubt that if you were to re-write them
now, most of them would be quite different. :-)

Hi, I'm working on my first POE program (using POE 0.1203). It's purpose is
to replace a hodgpodge of patches, scripts, and procedures between my
database and (extremely busy) webserver.
WHOA.

I mostly get POE, I think. I've even got some working code. But still,
there is some weirdness
