Foo::Bar vs. Foo::Bar
I'm having problems with cached modules, and I'm wondering if somebody will help me out. I have a module I've written, let's call it Foo::Bar. Well, I have several projects running under mod_perl that use this module. I add to the module from time to time, and thus newer projects will rely on a newer version of Foo::Bar. All these projects are running on the same server, in the same mod_perl environment. So there's a problem when one version of Foo::Bar gets cached and one script needs another version, but tries to use the one in memory 'cause all it knows is that it needs Foo::Bar. Thus Project A gets run first and uses an early version of Foo::Bar. That version gets cached and when Project B gets run, it has problems 'cause it uses the early version of Foo::Bar. Each project has their appropriate 'use lib qw()' paths set. This is what my apache config looks like for the project dir: SetHandler perl-script PerlHandler Apache::Registry Options +ExecCGI +Includes PerlSendHeader On PerlInitHandler Apache::StatINC PerlSetVar StatINCDebug On And I'm using Apache 1.3.12 and mod_perl 1.24. Thanks for any help you can give. --Ade.

Dmitry is right, if you need more help, you should set Debug to 2 and set the error output as well as your the relevant part of your script. --Joshua _ Joshua Chamas Chamas Enterprises Inc.

You know, I thought that there was a problem here when I first saw this
email, but today I simply cannot reproduce it. When I run the example
program, everything barks.
Can you still reproduce this problem, and, if so, could you please send me
a complete, working perl program as a demonstration?

Can you explain how your approach is different from the ones in IPC::Shareable, IPC::Cache, IPC::SharedCache, IPC::MM (using shared hash), File::Cache, and BerkeleyDB, and list some advantages/disadvantages of your module? Your module may be great, but it's hard for people to know which one to use in this crowded field without some explanation of the differences. - Perrin
startup file
Hello, all, I'm quite noew to modperl. I've written a cgi, using cgi.pm that I am moving to modperl. The cgi is written as one main program, with a number of subroutines spread across three libraries that are required into the main program. If I list the main program in my startup file, so it is loaded on server startup, does it load the external libraries as well?

Aborting Apache startup during PerlInitHandler
Hi!
I have got a PerlInitHandler that does some config parsing etc.
I would like Apache to stop starting up and to print out some error
message ("Config Directive blabla missing" or something like that) if
an error occures during config parsing. (As it is happing when
something is wrong with the Apache Config (httpd.cfg ...))
How can this be done?

Thanks Joshua I was aware that Apache::ASP did all the some of these things but not all of this - and I see you will be including some XML support I am truely impressed (the caching bit, and the script environment changes). My aims have thus far been to write my own modules that just do what I need and no more, so that Firstly its efficient (no excess code, not to say Apache::ASP has any of that ;-), and Secoundly to learn some more. This does mean I reinvent the wheel code wise, compared to projects like yours, HTML::Embperl, HTML::Template - but I'll learning in the mean time. I am not expecting to release anything on CPAN or for the code to be used by anyone else. If anything I've been introduced to HML::Template - which is just the lightwieght templating module that would help with my present (work) project (I'd use my own module, but using a maintained CPAN module would be better for my clients in the long term (i.e after I've left)).

[OT] strange mod_rewrite behaviour (for Apache::Session support)
Hello,
I am in the process of implementing persistent sessions using
Apache::Session with the session_id stored in the URL and it mostly
works. In the HTML::Mason autohandler there is the following filter:
<%filter>
$r->pnotes("cookie") # mangle URL only if cookie is missing
|| s#\bhref\s*=\s*"(/(?!S=)[^"\s]*)"#href="/S=$session{_session_id}$1"#gi;
... which adds the session_id to all href links, only if the browser
doesn't return any cookie.
Now in httpd.conf there is a mod_rewrite rule inspired by a recent
thread on the modperl list:
RewriteRule ^/S=([^/]+)(/.*) $2 [E=AF_SID:$1]
This removes the session_id from the URL and adds it to the AF_SID
environment variable. This works well for all absolute URLs (starting
with a /) which is puzzling because I remember reading in this thread
that this technique mandated _relative_ URLs.
The rewrite rule fails only in one case, the root URL:
http://my.site.com/S=1d2e580af1e31cf2/Sell/index.html
... is correctly converted to
http://my.site.com/Sell/index.html
... *but*
http://my.site.com/S=1d2e580af1e31cf2/
... fails with a 404 NOT FOUND error
>From the rewrite log:
127.0.0.1 - - [23/Jul/2000:15:57:31 +0200] [apartia.int/sid#815769c][rid#8149464

[Sun Jul 23 15:57:31 2000] [error] [client 127.0.0.1] File does not exist: /
... so after tinkering with various mod_rewrite options for a while I
changed the RewriteRule to:
RewriteRule ^/S=([^/]+)(/.*) %{DOCUMENT_ROOT}$2 [E=AF_SID:$1]
... and now everything works fine.
But I'm still not happy because I don't understand _why_ it works.
Please let me know if you have a rational explanation.
TIA

Looking at that lead me IPC::SharedCache - which is almost exactly what I have decided to do - albiet Sam Tregar's implementation appears alot better. My Implentation of the template is very simple - i.e you give it a template, then ask it to sub in all the values into the tag locations, and return a scalar ref. There are a few other methods (for defining tags and their values) -p but thats it. I seem to have implemented an HTML::TemplateLite and IPC:SharedCacheLite I have learned alot and can always reuse the code in the orginals - this is after all perl Thanks again. Greg Cope
