disk space requirement
How much space required to install the mod_perl?(necessary files excluding the documentation, etc.) As what I have read, I need also to install the Perl interpreter when using mod_perl. How much size the interpreter requires? Your answers is very much appreciated. I have some hardware limitations which might not able to install such packages.

How much size the interpreter requires? Your answers is very much appreciated. I have some hardware limitations which might not able to install such packages. A rough calculation is simple: % du -s /usr/src/apache-1.3.9_dev/ 10853 /usr/src/apache-1.3.9_dev % du -s /usr/src/modperl-1.21_dev/ 3195/usr/src/modperl-1.21_dev These are the sizes of the directories the apache and mod_perl were build from (after running 'make' in both). Since they include sources, docs and other stuff that aren't being installed. You need about 10M+ in size. I don't have a perl source after 'make' handy, but it's about another 20Mb. You will want to install other Perl modules from CPAN, so estimate at least a few more Mbs... This last number depends on your needs. I thought we have passed the times where additional 10Mb would be a question of life or death... Oh well.

Apache::Session. Why Apache? Why Session?
I've been going through the code of Apache::Session trying to understand how it works and how to use it when it occurred to me that the module doesn't really measure up to it's name. I mean IMHO, the name is a bit misleading. First. It looks like the module's code is completely self-contained and doesn't depend on anything Apache. If my observations are true, why is it in the Apache hierarchy (except possibly for historical reasons)? Second. It doesn't really manage sessions. It provides implementations for different models of persistent storage (memory, FS, DB, etc.). A complete Apache-based session managing mechanism (with session initialization, destruction, auto-expiration, etc.) still has to be coded on top of it. Any comments? Shouldn't it be renamed?

ANNOUNCEMENT: NEW VERSION: HTML::Template 0.96
ANNOUNCEMENT: NEW VERSION: HTML::Template 0.96 NAME HTML::Template - a Perl module to use HTML Templates CHANGES 0.96 - Added "ESCAPE=1" option to TMPL_VAR to HTML-escape variable values. (Peter Marelas, thanks!) - more bug fixes (David Glasses, James William Carlson - thanks) - even *more* code cleanup! - new FAQ concerning pre-loading templates and mod_perl. DESCRIPTION This module attempts make using HTML templates simple and natural. It extends standard HTML with a few new HTML-esque tags - TMPL_VAR, TMPL_LOOP, TMPL_INCLUDE, TMPL_IF and TMPL_ELSE. The file written with HTML and these new tags is called a template. It is usually saved separate from your script - possibly even created by someone else! Using this module you fill in the values for the variables, loops and branches declared in the template. This allows you to seperate design - the HTML - from the data, which you generate in the Perl script. This module is licenced under the GPL. See the LICENCE section of the README. AVAILABILITY The module is available on CPAN. You can get it using CPAN.pm or go to: http://www.cpan.org/authors/id/S/SA/SAMTREGAR/ MOTIVATION It is true that there are a number of packages out there to do HTML templates. On the one hand you have things like HTML::Embperl which allows you to freely mix Perl with HTML. On the other hand lie home-grown variable substitution solutions. Hopefully the module can find a place between the two. One advantage of this module over a full HTML::Embperl-esque solution is that it enforces an important divide - design and programming. By limiting the programmer to just using simple variables and loops in the HTML, the template remains accessible to designers and other non-perl people. The use of HTML-esque syntax goes further to make the format understandable to others. In the future this similarity could be used to extend existing HTML editors/analyzers to support this syntax. An advantage of this module over home-grown tag-replacement schemes is the support for loops. In my work I am often called on to produce tables of data in html. Producing them using simplistic HTML templates results in CGIs containing lots of HTML since the HTML itself could not represent loops. The introduction of loop statements in the HTML simplifies this situation considerably. The designer can layout a single row and the programmer can fill it in as many times as necessary - all they must agree on is the parameter names. For all that, I think the best thing about this module is that it does just one thing and it does it quickly and carefully. It doesn't try to replace Perl and HTML, it just augments them to interact a little better. And it's pretty fast. DOCUMENTATION The documentation is in Template.pm in the form of POD format perldocs. Even the above text might be out of date, so be sure to check the perldocs for the straight truth. CONTACT INFO This module was written by Sam Tregar ([EMAIL PROTECTED]) for Vanguard Media (http://www.vm.com).
Apache::Sybase::CTlib problems..
Hi,
Hope somebody out there can help straighten me out with a problem I'm
having in using the Apache::Sybase::CTlib for persistent database
connections.
I've complied Apache 1.3.9 with mod_perl 1.21 (as a DSO) against Perl
5.005_03 on Redhat 6.0 (linux 2.2.5-15).
I've followed the instructions in the Apache::Sybase::CTlib.pm file for
configuring the httpd.conf startup.pl file:
httpd.conf:
.
.
.
SetEnv SYBASE /opt/sybase-11.9.2
.
.
.
PerlRequire conf/startup.pl
startup.pl:
use Apache::Sybase::CTlib;
Apache::Sybase::CTlib-connect_on_init("myuser", "mypass1", "myserver",
"mydb");
1;
Whenever I try to start the server (ie: /usr/local/apache/bin/httpd -f
/usr/local/apache/conf/httpd.conf), I get a message at my prompt stating
that the server has started, but no server appears in the process table
(ie. ps -ef | grep httpd) and no errors are written to the error_log.
Any ideas ?
Presuming that I can actually get this to work, how to I actually use
the db connection I've created ? Do I assign a global scalar (ie: $mydb
= Apache::Sybase::...) ??
puzzled...

Re: Apache::Filter: Can't locate object method TIEHANDLE
I think your assessment is correct, though I'm not sure what would cause it.
How about changing the following at line 72 for some info:
warn "Untie()ing STDOUT" if $debug;
warn "tied(*STDOUT) is " . tied(*STDOUT) . ", " . *STDOUT if $debug;
$info-{'old_stdout'} = ref tied(*STDOUT);
untie *STDOUT;

I know you said you don't like it because it has extra overhead, but would

the prepare_cached appraoch is just much more manageable.

I think Oracle 8 is doing some magic by parsing your SQL and matching it

You may also find that the use of bind variables become more and more
effecient when used in complex, multi-table joins.

Re: Apache::ASP Apache Authentication?
Jeremy, Did you ever find a solution to this auth problem ? I tried to recreate the error that you were having, but could not. I was using Apache::ASP v.16 (dev) v.17 on Solaris WinNT, with apache's 1.3.4, 1.3.6, and mod_perl's 1.17, and 1.20. I created a test directory with the .htaccess: FilesMatch "\.(asp)$" SetHandler perl-script PerlHandler Apache::ASP PerlSetVar Global /tmp PerlSetVar CookiePath / PerlSetVar SessionTimeout .5 /FilesMatch and then a sub admin directory with the .htaccess: AuthUserFile htpass AuthName "Administration Pages" AuthType Basic require valid-user and when browsing the admin directory, got the normal user/pass basic auth prompt. You had said that v.16 messes things up for you, but not v.15, but everything works for me with v.16, and there aren't any changes that I'm aware of that would create this behavior for you. There were some auth changes in v.16, but that was for when the ASP scripts handles the auth itself. The problem you have seems to be that something is getting in the way of the normal auth mechanism. Are there any error messages of note when this happens to you ? Sorry for my tardiness on this dealing. I've been behind on things because of a recent move. -- Joshua _ Joshua Chamas Chamas Enterprises Inc.

For some applications with lots of SQL statements, the prepare_cached appraoch is just much more manageable. Okay. I'll try it out tomorrow and post the results. However, my application uses this approach and I'd say it's in the 99th percentile with respect to number of different statements =:-) Regards, Jeffrey

However, my application uses this approach and I'd say it's in the 99th percentile with respect to number of different statements =:-) I just performed this benchmark. The Stage 3 optimization using prepare_cached gets 152.72 requests/sec. The end result is this: Zero optimization: 41.67 requests/second Stage 1 (persistent connections): 140.17 requests/second Stage 2 (bound parameters): 139.20 requests/second Stage 3 (prepare_cached): 152.72 requests/second Stage 3 (global references): 251.13 requests/second You can see that prepare_cached isn't much of an improvement over prepare. I've profiled this stuff in the past, and the prepare method really is quite expensive. A nice project for someone with sufficient spare time would be to optimize that code path. -jwb

For some applications with lots of SQL statements, the prepare_cached appraoch is just much more manageable. Some databases doesn't support caches of prepared plans. PostgreSQL for example. So I think Jeffrey's approach is more generic. But I agree with you if database supports this feature it's worth to use it. It is interesting that the Stage 2 optimization didn't gain anything over Stage 1.
