Re: code in perl sections executed twice in same process?

2009-11-17 Thread E R 
The perl sections don't seem to be executed in the children.

Is there a way to determine which pass you are in?

For large mod_perl apps, is there a way to avoid loading your code in twice?

Note I am using mod_perl 1.3.41.

Thanks,

 I believe it is normal, in the sense that Apache actually parses its
 configuration at least twice : one time just for checking, then it throws
 everything away and parses it a second time for real.

 Then it will even (probably) run your section again, each time it starts a
 new child process.

use a PerlChildInitHandler if you want to run code in the children.

In mp1, use $Apache::Server::Starting, and $Apache::Server::ReStarting.

code in perl sections executed twice in same process?

2009-11-16 Thread E R 
Hi -

I am using mod-perl 1.3.41 with perl 5.8.9.

The only perl I have in my config file is:

Perl
  warn This is a perl section in process $$ at time @{[time]}\n;
  sleep(5);
  warn Done sleeping\n;
/Perl

When I start it up in single process mode (-X), I'll something like
this on stderr (to the console):

This is a perl section in process 25597 at time 1258408992
Done sleeping

And also in the error log I'll see:

This is a perl section in process 25597 at time 1258408998
Done sleeping

The pids will be the same, but the times will be different (about 5
secs. apart.)

Is this normal, and what can I do so that the code in Perl
sections is only executed once in the parent process?

Thanks,
ER
