RE: Win32: Cannot load mod_perl.so into server
Sorry, I pressed the send button before I finished in the last message. Recently I posted a possible solution if apache fails to start as a service on NT.

Re: RFC: new module: Apache::FakeEnv
Hi! Geoffrey Young: there was a more advanced Apache::FakeRequest floating around somewhere... I think this was it, but I swore it was something on the dev@ list: http://marc.theaimsgroup.com/?l=apache- modperlm=98719810927157w=2 I knew this script (it was posted here, too), and while it is definitly better than Apache::FakeRequest, it still doesn't handle dir_config calls. Geoffrey Young: generally, I would think that feature enhancements to Apache::FakeRequest would be preferred over another module that is essentially the same - a better FakeRequest has been on the ToDo list for some time now... any chance you can expand the existing Apache::FakeRequest and offer a patch? Sure I could try to patch Apache::FakeRequest, but I think the changes are quite fundamental. What to the mantainers of Apache::FakeRequest (or mod_perl) think of this? darren chamberlain: Don't know about the rest, but I saw Config::General, which will parse an Apache config file into a hash. Very useful, and very well done. I took a look at this module, and while it parses simple Apache config files correctly, it won't work with more complex ones. For example, it doesn't handle Include directivec (altough I submitted a patch to the author, so it will work with Apache Includes) and it can't parse VirtualHost Sections correctly. This questions of my initial posting are still unanswered: * Is it possible to subclass mod_perl or Apache::Request from outside of Apache (i.e. in a plain perl environment) ? * If not (which it seems to be), what would be the best way to implement all (more or less..) mod_perl methods and subclasses (Apache::Request et.al) ? Can one use the C code that mod_perl is based on? (Well, I guess I can't because I've never done any real C coding ...) ? -- D_omm O_xyderkes http://domm.zsi.at M_echanen M_asteuei

Weird caching problem in windows browsers
hey guys i have a pretty big mod_perl system up and running and have run into a weird problem with browser caching (or rather, not caching) on windows. i have a series of complex forms that submit to and are generated by a mod_perl handler. each submitted form is validated and another form is generated. in some cases, there are about three or four forms in the sequence. for some reason, in windows, hitting the back button results in both IE and Netscape giving Warning: page has expired error pages. I have numerous places on the site that do this, and it's been working fine all this time. Now, the new forms all cause the error, whereas the old ones are still fine. I have been trying to figure out what's different between the old ones that work and the new ones but I can't really see anything. There are occasions with the newer ones where an entire sequence of forms submits to the same URL, like this: form method=post action=/path_to_my_handler/someNamedAction so I wrote some code to generate unique URLs for each subsequent POST and that still produces the same results. The weird thing is that if you refresh the page that produces the error, it will remember that page from then on and never show the error for that form again. Does anyone have any idea what might be causing this? I am stumped. It's also extra tough to debug because everything works perfectly in Linux so I have to run windows in VMware to even reproduce the error. Ugh. Kyle [EMAIL PROTECTED]

question on installing mod_perl to activePerl on win98
Hi: From your website http://perl.apache.org/distributions.html, I got message( see following) Win32 ActivePerl mod_perl ppms - suitable for builds 6xx. You can install this by, within the ppm shell, setting the repository to http://theoryx5.uwinnipeg.ca/cgi-bin/ppmserver?urn:/PPMServer and typing install mod_perl. This will also run a post-install script to install the required mod_perl.so to your Apache modules/ directory. I followed the instruction, but ppm can not find mod_perl, in fact I opened this link, nothing there. I really need to install mod_perl in my computer to do some projects, my operation system is win98, I appreciate to get your quick respond.

Re: Weird caching problem in windows browsers (solved)
hey all found the problem and it had nothing to do with caching or browsers or OSes, but it's worth a mention here for future reference. for debugging purposes, i had use CGI::Carp qw(fatalsToBrowser); in my handler. for the most part, it was useful, except in this case. deep down in one of my classes, i was using eval to trap a potential error. in the situations where that error occurred, i trapped it, logged a warning, and continued to generate a response that I returned. it seems, however, the CGI::Carp was somehow thinking that an error had occurred and it was *changing* the response code from 200 to 500. So the browser was getting a Status of 500 but my page was being generated, so I didn't know there was anything wrong with it. I took out CGI::Carp and it all works. M. Side effects. Yummy.

Persistant data accross processes
Hi all, I'd like a way to store complex data structures across Apache processes. I'velooked at Apache::DBI for an example: my tests say that he has to create a new dbh for every process. I've looked at IPC::Shareable, but it has to copy data. Meaning that I can only have a certain amount ofcomplexity to my data structures. Thoughts? ---Rodney BroomProgrammer: Desert.Net
mod_perl 1.25, CGI.pm and POST
We recently upgraded our Apache server from 1.3.12 with mod_perl 1.24 and
php 3 to 1.3.20 with mod_perl 1.25 and php4.0.5. This included an
unexpected upgrade from Perl 5.005_03 to Perl 5.6.0 since the new version
of Apache was compiled using Sun Workshop 5.0. However, since the upgrade,
I have noticed that several scripts (actually, every CGI.pm script) we used
to POST to now acts as if it is NOT being posted to. The following code
fails to return anything into @parameters despite working yesterday (before
the upgrade):
my $q = new CGI;
my @parameters = $q-param();
However, if I change the submission type from POST to GET, the script
starts functioning perfectly.
Does anyone know what would cause this type of behavior? I am at a loss as
to how to proceed ... I am including below an example script which exhibits
this behavior consistently on my server.
The server is a Solaris 7 64-bit, Sun Ultra Enterprise 250 (dual processor).
#!/usr/bin/perl -w
# This file is intended to be INCLUDED from an SHTML file,
# NOT directly executed!
use strict;
use CGI;
my $q = new CGI;
my @parameters = $q-param();
print $q-header;
# Now display the search form
print $q-start_form(-method = 'post') . $q-start_table({align = 'center'});
print BR\n;
print $q-textfield(-name = 'title',
-size = 32,
-maxlength = 255);
print BR\n;
print $q-submit({name = 'POST Search'});
print BR\n\n;
print $q-end_form();
print $q-start_form(-method = 'get') . $q-start_table({align = 'center'});
print BR\n;
print $q-textfield(-name = 'title',
-size = 32,
-maxlength = 255);
print BR\n;
print $q-submit({name = 'GET Search'});
print BR\n\n;
print $q-end_form();

{
foreach my $elem (@parameters)
{
print $elem = . $q-param($elem) . br\n;

RE: Requests using If-Modified-Since cause response Set-Cookie to be discarded
maybe storing 'last-access-time' on the server, instead of in the client-side, via cookie, would solve this snafu? But if you want to give out a new cookie on every request ? How would you prevent them from copying or tampering with the contents? a MD5-hash would stop them from changing values, but they could still copy the cookie, so the next idea is timeouts, and when you use timeouts it would be nice if the user don't have to login every couple of minutes, but would get a new valid cookie automaticly... Aside from the fact that a server-side tracking system is bound to become incredibly unmanageable, very quickly, in terms of server-side storage... One of the methods I've used is to include a timestamp in the user's info (incl the MD5 hash? see the Eagle for Encryption of Cookies w/ MD5). THEN, when deparsing the cookie, DELETE it if the timestamp is too old. THEN, you either have a valid, non-timed out session, or no session at all (which is what you were worrying about in the first place, no?). If your system is based on session LENGTH (ie this ticket is good for one hour from last access), all you have to do is re-set the timestamp to the current time. HTH! L8r, Rob
Persistance in mod_perl
Hello all, We are just getting started with mod_perl, installed on Sun Solaris 2.8, Apache 1.3.20, Perl 5.005_03. I have DBI and Oracle DBD installed. In our application, we want to have a user login to the database, and maintain the connection until they logoff. We also want to maintain state between various forms as the user utilizes the application. We've read the mod_perl FAQ, parts of the Apache Modules book, info in Apache Server books, the CGI.pm perldoc, etc. We're pretty confused at this point about how to proceed. For example do we need any additional modules to maintain the database connection and/or form state? Each time you call your Perl program that is available via mod_perl (via direct URL or forms-generated URL), is a new instance created? If not, what is the entry point into the existing instance? For example, should our Perl program sit in a loop reading URLs? Does each user get their own instance of the Perl program? Or, is it shared among users? Does the Perl program run as a thread in the httpd process? How / when does the Perl program terminate? TIA for any assistance you can provide!

I have DBI and Oracle DBD installed. In our application, we want to have a user login to the database, and maintain the connection until they logoff. We also want to maintain state between various forms as the user utilizes the application. well, each of these is a separate function... you can use Apache::DBI for persistent connections, and modules such as Apache::Session or Apache::AuthCookie for maintaining state. In the end, though, state implementation is entirely up to you - mod_perl and CPAN only provide access to the Apache API and a suite of nice tools to choose from, not an entire shrink-wrapped solution (although some modules certainly do approach that, like AxKit and HTML::Mason) We've read the mod_perl FAQ, parts of the Apache Modules book, info in Apache Server books, the CGI.pm perldoc, etc. We're pretty confused at this point about how to proceed. most of the answers you will need are contained within the Apache modules book (the eagle book) and the mod_perl guide (perl.apache.org/guide). the book is worth reading a few times to really understand how apache works, the request cycle, the prefork Apache model, etc. in general, most people start by porting their legacy CGI scripts to mod_perl, then get comfortable with the mod_perl API, then move to mod_perl handlers when creating an entire web application. you can, of course, choose to remain at any level - whatever works for you and your application's needs... For example do we need any additional modules to maintain the database connection and/or form state? yes, as mentioned above. Each time you call your Perl program that is available via mod_perl (via direct URL or forms-generated URL), is a new instance created? no If not, what is the entry point into the existing instance? the first chance you get to interact with a request is via the PerlHeaderParserHandler - see the request cycle diagram in the eagle book. For example, should our Perl program sit in a loop reading URLs? that's what Apache does for you :) Does each user get their own instance of the Perl program? Or, is it shared among users? there is a separate perl interpreter for each Apache child process. Does the Perl program run as a thread in the httpd process? no, it's embedded (at least with 1.3) How / when does the Perl program terminate? each time an Apache child process terminates, either through normal Apache child management, the child_terminate() method, or a segfault (but only rarely :) my advice is to read through the entire Eagle book and take some time to digest it. then start to apply the API to various parts - a PerlLogHandler is a nice way to start since it doesn't interfere with requests if you mess up and logging is a pain without it. or, you can forget all of this and post a consulting request - there are lots of talented folks here looking for work... ;) HTH --Geoff

Re: SSI Lost with Mod Perl?
Hi Perrin I've given Filter and SSI a shot according to the perldocs. It didn't work. I stated to hhack on some of the problems, which first involved in the make install depositing them in the wrong diretory, and then they SSI needed use Apache::Filter statements added. Finally, Filter cam back with an error that something or other $r wasn't a hash reference, which would not be a quick fix. So I've sort of hacked up my own little SSI for the time being and deposited it in the modules. I'm missing something in my understanding at this pointbut this project has me climbing a wall, and I'm pushing a head for the time being. I had a similar problem at one time with embperl and we had to also hack that together. I'm definetely bathing in a Brooklyn Larger Bath when this is done.

strange uninitialized value error.
I've been seeing these reasonably often on one server in my error log.
Use of uninitialized value.
Use of uninitialized value at /website/perllib/MLM/MLMhandler.pm line 56.
This is the relevent snippet of MLMhandler:
sub handler {
my($r) = @_;
# only works on main request
return DECLINED unless ($r-is_main());
warn r-uri is undef unless defined $r-uri; debugging?!?!?
my $subr = $r-lookup_uri($r-uri); # uri is relative to doc root
unless ($subr) {
warn error looking up '.$r-uri.';
return SERVER_ERROR;
}
...
}
line 56 is the call to $r-lookup_uri().
Where might the uninitialized value be coming from? Even after these
warnings are issued, $subr is defined.
