Detecting graceful restart

[Javier]

Hello,

Does anyone know if it's possible to hook into Apache
graceful restarts?

I tried PerlRestartHandler, but it doesn't seem to get
called. I see it called when I do apachectl startssl,
but not apachectl restart nor apachectl graceful.

None of the documentation I've found mentions wheter
it gets called only for plain restarts or for graceful
restarts also.

Thanks!

Re: Detecting graceful restart - wacky $$

Never mind. It was a mistake on my part. I was setting it with 
push_handler() in my startup.pl, so of course it didn't persist. Once I 
switched to setting it in the httpd.conf it was called on every restart, 
graceful or not.

Now I'm having a different problem. In my restart handler I print out 
the PID using a simple 'warn pid = $$\n. I was expecting it would 
print out the PID of the parent (listener) Apache process, but the PID 
that is printed does not exist in the process table, and is in fact the 
real Apache parent PID - 1. Getting the PID with POSIX::getpid produces 
the same result.

I'm baffled by this. Can anyone shed any light?

Can't load mod_perl in Solaris 8

[Javier Chicharro]

  I've compiled mod_perl-1.26 (and I tried with 1.25 too) for Apache
1.3.20 in a Solaris 8.   When I start apache I get this error :

Syntax error on line 222 of /opt/apache/conf/httpd.conf:
Cannot load /opt/apache/libexec/libperl.so into server: ld.so.1:
/opt/apache/bin/httpd: fatal: relocation error: file
/opt/apache/libexec/libperl.so:
symbol PL_markstack_ptr: referenced symbol not found
/etc/init.d/apache start: httpd could not be started

(The line 222 is the LoadModule for mod_perl)


  When I do ldd of libperl.so and httpd, seems that it finds all
dependences.


  Has somebody any idea about this problem?

 Have a look in mod_perl-1.26/SUPPORT and post the information it suggests.
 
 Did you compile your Perl?  What compiler are you using?

  Yes, I compiled my Perl using Solaris cc.

that project now, and it will be helpfull to read another source code.
Greetz and sorry for my poor english level.
