Re: Apache2::Reload - Very fickle, or is it just me?
Hmm, I see. Interesting points, all noted. I also just realized it might have to do with which of the many apache children get which requests and when. I'm hoping that setting MaxRequestsPerChild to something like 1 or 2 (as opposed to the default 1) will help ease the pain. -Patrick P.S.

I thought the solution would be to build apr and apr-util from source as dictated in the apr/apr-util >= 1.2 section in these docs: http:// httpd.apache.org/docs/2.2/install.html So I did, and then I configured and built and tested mod_perl-2 with: perl Makefile.PL MP_APXS=/opt/apache2/bin/apxs MP_APR_CONFIG=/opt/apr/ bin/apr-1-config && make && make test But alas, I got the same unresolved symbol errors on the "make test" part. What in the world am I supposed to do to fix this? I'm totally at a loss :-( Patrick R.
Re: Error- Attempting to Build Apache with mod_perl, no luck
Follow the steps in the section entitled "Installing mod_perl with
mod_ssl (+openssl)" on http://modperlbook.org/html/ch03_06.html to
the letter and everything should work out smoothly. Also, consider
using Apache 2.2.2 and mod_perl-2 instead. Lastly, buy this book:
http://www.oreilly.com/catalog/pmodperl/ or optionally read it
online: http://modperlbook.org/index.html

I'm really at my wits end trying to figure out why it won't work. I

Re: Sessions with mod_perl2
There is a plethora of different ways to handle sessions in perl driven websites. I'll throw in my 2 cents by describing how I've always liked to do it. My solution assumes that your using an SQL database for persistent data storage; but that obviously isn't a requirement, there are a lot of ways to manage persistent data. I also assume that your using mod_perl-2. 1) Use libapreq2's Apache2::Cookie to give the client a cookie such as "SID=57de5d0d-8315-0410-9c71-f10f4dd80f37" where 57de5d0d-8315-0410-9c71-f10f4dd80f37 is a UUID generated by libapreq2's APR::UUID module. Three cheers for libapreq2! :-) Subsequently store the UUID into a database. 2) Check for a session cookie when a client connects to the site, again using libapreq2's Apache2::Cookie. If a session cookie exists, use a short and sweet SQL statement (via DBI of course) to fetch the session data from the back-end database and then a subsequent statement to store the fetched data in various variables for the rest site's code to use. 3) Have a single subroutine named, for example, store_session_data called with arguments such as store_session_data(UUID=> "57de5d0d-8315-0410-9c71-f10f4dd80f37" username => "rutski89", favorite_color => "blue", auto_login => "yes") which then does on the fly construction of an SQL statement to insert the session data into the database. It's a step up from using CGI::Cookie in terms of the amount of work you have to do, but it's not too hard to implement. Personally, I enjoy the extra level of control over back-end storage. Patrick R. On Jun 6, 2006, at 4:48 PM, Matthew wrote: It could be that I just don't understand completely the nature of mod_perl, but here goes. Reason I'm confused is because there exists CGI::Cookie for handling cookies in MP2, but there's also the libapreq library "for MP2". It seems to me that the apreq lib is more "MP2 Native" than CGI would be. Am I wrong? Are they equally 'native' ? With that in mind, I'm looking for some module, that I'm sure exists, that can manage sessions. I found Apache::Session but I couldn't tell if it was MP2 native. Is there something else I should be using for sessions that is 'better' with MP2? Thanks, Matthew
use warnings logging
This post is in the context of mod_perl-2 handler's such as PerlResponseHandler MyModule::handler().When "use strict" in one of my modules has something to complain about it puts an error message into the vhosts's error log as any good warnings/errors module should, for example /www/addons/logs/error_log. However "use warnings" in my handler's likes to put all of it's message into the server's global error_log, which is /opt/apache/logs/error_log. This is obviously very unsuitable since error messages from multiple vhosts will go into the same log file! Madness!There has to be a way to fix this, but how?Patrick R.
