No, the latest stable Apache version is 2.0.44. However, you should
probably get the stable 1.x version, 1.3.27, since mod_perl 2.x is not
really stable yet. See http://httpd.apache.org

PLEASE spend some time at http://perl.apache.org perusing the VERY
comprehensive and clear documentation. I am not aware that you _need_ perl
5.8 to compile the latest apache and mod_perl, but you might as well get
it now since you are upgrading those packages too. perl 5.6.1 eould also
be fine; perl 5.6.0 has problems.

Silly Newbie Question: cookies and such
Unfortunatly, I find myself with a silly newbie question: I need to make an Apache module (not a Registry script) which will: 1. Check for a cookie, and if not there, pushhandler to a module for logging in (keeping the original request at hand for use after they succeed in logging in). 2. Extract data from the cookie (encrypted for security?) 3. Based on data from both the query string ($r-args?) and from data in the cookie, pushhandler to another module. I have looked at Apache::AuthCookie - it didn't seem to make much sense to me. Apache::Session looks promising, but the instructions don't say how to set up the mysql tables, etc. My worst problem is that I haven't had occasion to deal with cookies much (setting, checking,etc.) in the past and I know this is hampering my understanding. Can anyone give me a general overview (use this module, this way, etc.)? I'm not totally new to Apache Modules, but my experience is gleaned from writing modules already pushed into the handler stack by PerlTransHandlers written by someone else. I don't want to use PerlTransHandler, just PerlHandler, so I can use Location in perl.conf. In conclusion: I'm making a system/site where no .html files even exist. I need to handle security via a mysql db, and to push handlers based on a part of the url and a piece of the cookie which identifies the user as either a teacher, student, or parent (oops... I gave it away ;-) Jonathon Robison

You should definately be using Auth::Cookie for this. I would give the docs
another read. It took me a couple of tries to get it working successfully,
but I have implemented it in about 4 or 5 applications, and it works
flawlessly.
With Auth::Cookie it will handle the cookies for you, it will do the
redirection to your login page for you, and it can handle logouts as well (by
expiring the cookie).
As for Apache::Session, it is really just a keyed data store with expiry
times. You give it some data, and it gives you a key. If you come back
later and give it the same key, it gives you back your data.
A lot of people use Auth::Cookie and Apache::Session together to build a
session management system, but I prefer just using a ticket based system with
Auth::Cookie alone (See the Eagle book on how to do ticket based
authentication). I have included a sample Auth::Cookie implementation that
might give you some ideas. It is not complete, but it might get you going (I
have stripped out some of the irrelevant code, so it probably won't work out
of the box). Also you will have to provide your own login.pl and logout.pl
scripts (I would use the examples that come with Auth::Cookie until you get a
working system, then you can look at building your own.
In conclusion: I'm making a system/site where no .html files even exist.
I need to handle security via a mysql db, and to push handlers based on
a part of the url and a piece of the cookie which identifies the user as
either a teacher, student, or parent (oops... I gave it away ;-)
After Auth::Cookie has finished it's phase, it will set the REMOTE_USER
environment variable to the user that logged in. You could just as easily
set this to 'teacher' or whatever. Then your content handler can look at
this variable and decide what to do.

As for configuring, if you have Apache set up already, the configuration and use is very similar to Unix - see http://take23.org/ and http://perl.apache.org/, especially the guide, for lots more info on that. There's a sample Win32 httpd.conf at http://theoryx5.uwinnipeg.ca/ppmpackages/httpd.conf-perl that contains a number of common directives used for mod_perl related things.

The second program is taking advantage of the PerlSendHeader feature.
This is mostly a compatibility feature, I would tend to think that it
might be slightly slower (because mod_perl has to watch for the empty
line).
The first program should be a very small amount faster, as far as I
know, but the second has a partial advantage of portability to
non-mod_perl regular CGI environment. I say "partial", because you test
for $ENV{MOD_PERL}, which you don't need to do.

Newbie question about AuthCookieDBI
Hi all, I am a newbie user of mod_perl trying to work with Apache::AuthCookieDBI and have been running into several obstacles. I'm hoping someone can point me in the right direction. I just installed Apache::AuthCookie successfully and was able to get it to work with the necessary changes in my httpd.conf file. Now I want to use Apache::AuthCookieDBI to authenticate against a database table. However during my installation, while doing the 'make test' I get the following error message --- Can't locate object method "module" via package "Apache" at /usr/local/lib/perl5/site_perl/5.6.0/Apache/DBI.pm line 202. Compilation failed in require at blib/lib/Apache/AuthCookieDBI.pm line 41. BEGIN failed--compilation aborted at blib/lib/Apache/AuthCookieDBI.pm line 41. Compilation failed in require at test.pl line 11. BEGIN failed--compilation aborted at test.pl line 11. make: *** [test_dynamic] Error 255 When I do a 'make install' after this, it appears to install correctly.

Newbie question about AuthCookieDBI
Hi all, I am a newbie user of mod_perl trying to work with Apache::AuthCookieDBI and have been running into several obstacles. I'm hoping someone can point me in the right direction. I just installed Apache::AuthCookie successfully and was able to get it to work with the necessary changes in my httpd.conf file. Now I want to use Apache::AuthCookieDBI to authenticate against a database table. However during my installation, while doing the 'make test' I get the following error message --- Can't locate object method "module" via package "Apache" at /usr/local/lib/perl5/site_perl/5.6.0/Apache/DBI.pm line 202. Compilation failed in require at blib/lib/Apache/AuthCookieDBI.pm line 41. BEGIN failed--compilation aborted at blib/lib/Apache/AuthCookieDBI.pm line 41.

BEGIN failed--compilation aborted at test.pl line 11. make: *** [test_dynamic] Error 255 When I do a 'make install' after this, it appears to install correctly. However I run into trouble when I try to modify my httpd.conf file to use Apache::AuthCookieDBI. When I add the line --- PerlModule Apache::AuthCookieDBI to my httpd.conf file and restart the server, the server returns a message that it has restarted successfully, but in fact doesn't actually start.

RE: Newbie question to mod_perl and Apache::DBI
Apache::DBI will call push_handlers on to issue a rollback if AutoCommit=0
in your connect string...
but the problem may not be with you... looks like a bug (somewhere):
if(!$Rollback{$Idx} and $needCleanup and Apache-can('push_handlers'){
...
}
looks like calling Apache-can('push_handlers') is returning true even
though you didn't activate PERL_STACKED_HANDLERS. I wonder if somehow can()
isn't correctly capturing the build-time arguments (something to look
into...)
at any rate, the quickest way to fix this is to rebuild mod_perl with
EVERYTHING=1 or PERL_STACKED_HANDLERS=1 (or don't set AutoCommit=0 in your
connect string if you can't rebuild it now...)
try these and see if they make a difference...

yup, it's a bug...
#!/usr/bin/perl
use Apache::MyConfig;
my $r = shift;
$r-send_http_header('text/plain');
print "can push_handlers\n" if Apache-can('push_handlers');
print "but PERL_STACKED_HANDLERS: ",

basically Apache-can('push_handlers') returns true even if

I guess that at some point this worked correctly, otherwise Edmund wouldn't
have coded it that way?

Apache::Registry newbie question -- CGI state
I am trying to implement Example 2-14 in Stein and MacEachern.
Here's my code:
#!/usr/bin/perl
# file: hello.cgi
use CGI qw(:standard);
use strict;
my $name = param('name') || 'Anonymous';
print header(),start_html(-title='Yo!', -bgcolor='yellow'),
h1("Hello $name"),
p( "To change your name, enter it into the text field below and press",
em("change name.") ),
start_form(),
"Name: ",
textfield(-name='name', -value='Anonymous'),
submit(-value='Change Name'),
end_form(),
hr(),
end_html();
It works once -- BUT -- the value entered after the first appearance with
'Anonymous',
sticks and never changes
despite submitting the form again and again.
I thought that each invocation via CGI would change the value of param('name')?
I understand the code has been compiled once and is now running thru
Apache::Registry.
Nevertheless, shouldn't new param() values be visable?

Extreme Newbie Question
Let me apologize in advance if this is covered on a FAQ somewhere, or if this is the wrong place for this question. I've looked on the Apache web sites and in "Administering Apache" by Arnold, Almeida, and Miller but no luck. I'm just trying to get started with Apache and Perl on WinNT. I've been using IIS (with Perl), and would like to switch to Apache. I'm having trouble with getting Perl CGIs to run. I was able to get a basic "Hello world" (compiled C) CGI working, but not a simple "Hello world" Perl script. When I try the script's URL I get: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. In the error log I get: (2)No such file or directory: couldn't spawn child process: g:/apache group/apache/cgi-bin/test.pl The file's there, and since a missing file generates a "Not found" message, something else is going on. I suspect that Apache is trying to execute test.pl as an executable, and doesn't know it should send test.pl to Perl.exe. So is there some sort of "Set Interpretter" function in httpd.cnf I need to use? The only changes I made to httpd.cnf was to set the admin email to my email. I decommented #AddModule mod_perl.c but that caused Apache to refuse to start. Any help would be greatly appreciated, Gaf
Extreme Newbie Question
Nevermind, after searching on altavista for a couple hours I found a page that explained I had to use the #! notation (its not just for Unix anymore!) The test script works fine now. Gaf
Code Reuse (newbie question)
Basically I'm a bit stumped by how perl lets us reuse code snippets. I
can't seem to bend modules to what I need to do exactly:
I'm using Apache and mod_perl. Each perl script will produce a dynamic web
page. Now, with each script I need to recover the session variables I'm
saving (using Apache:Session:File) and also verify account name and
password:
#
use vars qw(%session);
eval { tie %session, 'Apache::Session::File', $authid, { Directory =
'/tmp/sessions' } };
if ($@) { print redirect("LOGIN.pl?CAUSE=FailedSessionTie"); exit; }
if (time() $session{expire_time}) { print
redirect("LOGIN.pl?CAUSE=TIMED_OUT"); exit; }
$session{expire_time} = time() + SURVEYDESIGN::survey_expire();
#
Basically this chuck of code that I want to replicate across scripts is
going to grow/shrink/change rapidly in the coming weeks as I toy with the
project.
My problem seems to be that I can not include/inherit a chunk of text, but
rather need to place code in a separate package for reuse. But I don't see
how that allows me to recover sessions and setup variables in the main
package.
Any input (or a redirection to a good FAQ) would be very welcome! Thanks.

Newbie question on Apache::Debug::dump
Sorry if this has been asked before but I have been unable to find the answer
(not in perldoc, apache modules book, searching archives):
I would like my perl compilation and process errors to be written to an HTML
page if/when they occur, in the same way they are written to stdout when I run
from the command line.
I thought that Apache::Debug::dump would do this, am I correct??
I am unable to make it work though. I can't seem to find any examples of how to
use it, perldoc is too brief for my limited skills, the apache modules book
(eagle) says:
"The three arguments to dump() are the request object, an error code to return
to Apache... and an error message..."
What is a "request object"?
No matter what I do, all I can produce is that "OK" server error page. My perl
code is a simple: give userid, password, database, sql query, connect to my
database (oracle) and display the results.
Can someone please give me an example of how to use dump()? Or if you have a
different suggestion.
Appended is my simple perl code and HTML error page
Thanks

Re: Newbie question on Apache::Debug::dump
The request object is $r Craig On Sat, 19 Aug 2000, Jay Strauss wrote: Sorry if this has been asked before but I have been unable to find the answer (not in perldoc, apache modules book, searching archives): I would like my perl compilation and process errors to be written to an HTML page if/when they occur, in the same way they are written to stdout when I run from the command line. I thought that Apache::Debug::dump would do this, am I correct?? I am unable to make it work though. I can't seem to find any examples of how to use it, perldoc is too brief for my limited skills, the apache modules book (eagle) says: "The three arguments to dump() are the request object, an error code to return to Apache... and an error message..." What is a "request object"? No matter what I do, all I can produce is that "OK" server error page. My perl code is a simple: give userid, password, database, sql query, connect to my database (oracle) and display the results. Can someone please give me an example of how to use dump()? Or if you have a different suggestion. Appended is my simple perl code and HTML error page Thanks Jay

Check the mod_perl guide for the usage of require() and do(). You probably
want to use do() instead of require().

Subject: newbie question - require
In moving from CGI.pm to mod_perl, I ran across the common error with
functions that exist in scripts pulled in with 'require'.
Mod_perl_traps.html had the solution. Similarly, am using ('require')
another file which holds all the hash tables (countries, states, etc.)
that my scripts need to reference. It appeared to work fine in CGI.pm,
but with mod_perl, the info in the hash tables seems to be found "every
other refresh" (which has me stumped).
Would anyone be able to suggest a solution or reading material on this?
Thanks in advance.

Newbie Question -
Good Morning,
I just started using mod_perl, I'm still using the CGI.pm module, but I
plan
to convert. I've loaded the Apache::Registry and I'm experiencing a
strange
problem.
I have this snippet:
print "Content-Type: text/html\n\n";
print_template(file_handle, *file_handle_ref) {
open file_handle()
while (file_handle()) {
manipulate current_line
print file_handle_ref
current_line
}
}
where "*file_handle_ref" could be a reference to STDOUT,
this snippet worked fine, but now it stopped working, instead
I get the message "The document contained no data"
Also in my location tag I also have the directive "PerlSendHearder On"
however, when I remove that line all I get is the string "Content-Type:
text/html"
displayed in the browser.
Thanks,
Pierre

are you saying you re-open STDOUT? if so, you break the tie to the
browser. but, i don't understand the code you've posted, if you have a
tiny example that we can actually run, we should be able to see the
problem.

newbie question: extra Content-Type headers?
I apologize if this is a dumb question, but I just installed Apache and
mod_perl and all seems to have gone well. The trouble comes in when I try
to run a script using Apache::Registry and CGI.pm. I get an extra
Content-Type in the resulting page, and I can't figure out where it's coming
from.
First example:
#!/usr/bin/perl
print "Content-Type: text/html\n\n";
print "htmlheadtitleboo/title/head";
print "bodyh1I was here./h1/body/html";
This work fine.
Second example:
#!/usr/bin/perl
use CGI qw(:standard);
print header(),
start_html(-title='boo'),
h1("this doesn't work!!!"),
end_html();
This second example ends up printing "Content-type: text/html" at the top of
the page. Is there something in httpd.conf that tells the server to print
the content type automatically? Why does the first example work if the
second doesn't, if ultimately they should both end up printing more or less
the same thing.
If I run the second example as a regular CGI script (not under mod_perl) it
comes out fine.
so, I'm stumped. But I know it's something painfully obvious.
thanks,
-john.

Hi all, I hope you guys will forgive this question, but I am a complete beginner with CGI etc. We run an NT Server using Apache Web Server and I want to run Perl scripts on our web site to handle our administration forms. I loaded the Activeperl software onto the server, but it still doesn't run perl scripts. I have read heaps of stuff (most confusing) I have made changes to the httpd.conf file as outlined in some documents I read but then the service won't restart. I read a lot about the MOD-PERL but very little about what it is and how it works, is this my problem? Is anyone willing to tell me in SIMPLE terms what i have to do to get this thing working?

Re: Newbie Question
Hi Ian, We run an NT Server using Apache Web Server and I want to run Perl scripts on our web site to handle our administration forms. To get full advantage out of mod_perl, it is more interesting to use it on UNIX machines. But, in this community, we will encourage you to use mod_perl even if you are determined to use NT. I loaded the Activeperl software onto the server With the ActivePerl distribution, you can run Perl scripts in plain CGI mode, but you cannot use mod_perl. but then the service won't restart. You should provide a complete technical description of your problem. I read a lot about the MOD-PERL but very little about what it is and how it works, is this my problem? Yes. You should start by reading http://perl.apache.org/guide. Take your time to read this document carefully. Is anyone willing to tell me in SIMPLE terms what i have to do to get this thing working? You should understand that mod_perl is a bridge between Perl and Apache, which, apart from its technical excellence, allows Perl programmers to use their Perl culture while configuring and programming their Web applications not only at the application level (the script itself) but also at the system level (the server, i.e. Apache). Whether you use mod_perl or not, programming a Web application requires understanding how the Web works and how http servers work. Reading http://perl.apache.org/guide will attract your attention to mod_perl's major ambitions. Try to define what your application's ambition first of all, then look for corresponding guidelines in that document. Victor.
Newbie Question
Thanks for your responses so far, I know I have a lot of reading to do but I just thought I would add this to my first post. After loading Activeperl I changed the httpd.conf file by adding the following: Alias /perl/ c:/Program Files/Apache Group/Apache/cgi-bin Location /perl SetHandler perl-script PerlHandler Apache::Registry Options ExecCGI /Location PerlModule Apache::Registry PerlModule CGI PerlSendHeader On It was after adding this that the service refused to restart. I will obviously have to read a whole lot more before this is going to work. The annoying thing is that I just want to run a script to handle forms seems like a hell of a lot of effort for such a simple request :) Thanks all Ian * Ian Ollier - [EMAIL PROTECTED] Systems Administrator Queensland Centre for Schizophrenia Research Wolston Park Hospital, Wolston Park Road Wacol QLD 4076 AUSTRALIA ph: +61 7 3271 8592 fax: +61 7 3271 8567 mobile: 0411145593 website: http://www.qcsr.uq.edu.au Any opinions herein are my own and do not necessarily reflect my employer's views. *
Embperl problem (newbie question?)
Just trying out Embperl, and I discovered that (in my test of dynamic tables) the $maxrow and $maxcol variables are being set to defaults of 100 and 10 respectively and then obeyed, even though the $tabmode variable is set to 17. According to the documentation, these variables should only be obeyed when tabmode contains bits in the 64 and 4 position. My test called for 209 rows and 11 columns, and I was flummoxed for a bit until I started playing around with these variables. Am I missing something, or is it just a documentation inconsistancy? /edg Ed Greenberg __ Get Your Private, Free Email at http://www.hotmail.com
