Re: [Slashcode-general] Building a haxlash site ...

Actually, was all co-related ... once I switche dto using
_build_initial_queue instead of run, everything seems to be running great
...
I haven't looked much into it (other priorities in the code), but my guess
is that slashd is implementing its own run subroutine somewhere ..
Looking at the code for Schedule::Cron, even the original version
according to cpan, build_initial_queue was the first thing that happened
within the 'run' subroutine ...
When I changed the code to $cron->run(detach=>1), slashd was doing exactly
what I told it to .. forking off a Schedule::Cron process, which also took
a MySQL DB connection with it ... when process_tasks() came around again
(in slashd), it then fired off yet another Schedule::Cron forked process,
with its MySQL DB Connection, etc, etc ...
One thing I didn't try yet was to do:
$cron->run(detach=>0);
but I suspect that that woudl have stuck the slashd process within
Schedule::Cron's run loop indefinitely ...
So, I switched back to the original code, but changing the subroutine call
to be _build_initial_queue instead of build_initial_queue, which is what
the author of the Perl module seems to have renamed it too ... the
subroutine was there, just renamed ...
Right now, things seem to be running clean ...
