Apache has "mod_fcgi" (or was it mod_fastcgi?) which is a lightweight dispatcher - it interfaces to FastCGI applications. The FastCGI applications are separate processes, running as daemons. The handling of the FastCGI daemons can be done statically (eg; "run 5 instances of this app"), or dynamically (increase/decrease daemons based on load automatically). So, if I have an Apache server, with a hefty Perl App that takes up 10Mb RAM, then an Apache server with 50 daemons would take 500Mb. Having that app as a FastCGI and limiting it to 5 daemons would mean only 50Mb of RAM is required, but only 5 of those 50 daemons could access the application at a time - but those other daemons can do other things, like dish up static content, access other FastCGIs, etc... What's more, you can host FastCGI apps on different hosts, and there's a common protocol between webserver and CGI, so you can write the CGIs in any language, and have them work with any webserver with FastCGI support. IMHO, FastCGIs are a better way of doing applications, but don't have the versatility mod_perl has of digging into Apache internals. Don't get me wrong, most of what I do is in mod_perl, but part of that is because it's harder to layer content from multiple FastCGIs. -- .

ANNOUNCEMENT: HTML::Template 2.3
HTML::Template - a Perl module to use HTML Templates CHANGES 2.3 - New Feature: template tags can now span lines. (Roland Giersig) - New Feature: new() option 'filehandle'. (Roland Giersig) - Bug Fix: includes were broken in some cases using scalarref templates. (Lance Thomas) - Bug Fix: recursive include detection was broken for scalarref templates. (Mark Stosberg) - Bug Fix: cleaned up more 5.004 warnings. (Jere Julian) DESCRIPTION This module attempts make using HTML templates simple and natural. It extends standard HTML with a few new HTML-esque tags - , , , , and . 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. A Japanese translation of the documentation is available at: http://member.nifty.ne.jp/hippo2000/perltips/html/template.htm This module is licenced under the GPL. See the LICENCE section of the README. AVAILABILITY This module is available on SourceForge. Download it at: http://prdownloads.sourceforge.net/html-template/HTML-Template-2.3.tar.gz The module is also 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 won't start, strange dynaloader problem...
sorry if this has been answered before, didn't find anything in the archives, and I've done this at least half a dozen times before with no problems. Mandrake 8.0 apache-1.3.20 perl-5.6.1 mod_perl-1.25 I had problems compiling Apache::Request with the native Mandrake apache/perl, so I downloaded the latest stable versions and built a static "flexible" mod_perl httpd (but with DSO enabled in case I want to add more modules later) Things seem to work for the most part, but mod_perl is unable to load modules that have shared libraries. This the error I get for having use Apache::Request(); in my startup.pl [Thu Jun 28 16:04:01 2001] [error] Can't load '/usr/contrib/lib/perl5/site_perl/5.6.1/i686-linux/auto/Apache/Request/Request.so' for module Apache::Request: libapreq.so.0: cannot load shared object file: No such file or directory at /usr/contrib/lib/perl5/5.6.1/i686-linux/DynaLoader.pm line 206. Request.so is there, and I checked the directories leading up to it they are all world readable and after a su - nobody (who the web server runs as) nm Request.so worked fine. Also the directories under /usr/contrib are where my versions of perl live. Running startup.pl with the "normal" intepreter works fine, and I've seen a similar problem with Image::Magick, so it looks like some problem with the embedded perl and dynaloader. Any help would be greatly appreciated! -- [EMAIL PROTECTED]
CGI::Carp(fatalsToBrowser) not working with Apache::PerlRun
We are in the process of moving from strictly CGI to a mod_perl environment. Since I know we have many CGI programs that will not run correctly under mod_perl, I want to run them using the Apache::PerlRun handler instead of the Apache::Registry. We just have too many programs to recode. I included directives in the httpd.conf file to have all .cgi programs handled by Apache::PerlRun and all .pl files to be handled by Apache::Registry. The problem I am having is using CGI::Carp qw(fatalsToBrowser). When scripts are run with Apache::Registry, any fatal errors are output to the browser. When scripts are run using the Apache::PerlRun handler, the error is going to the log and not the browser. I just get Internal Server Error displayed in the browser. Below are the Apache configuration directives and a sample program. When the program has a .pl extension, I get the error output in the browser. When the same code is run with a .cgi extension, the error only goes to the log. Can anyone tell me what I am doing wrong? Thanks in advance.

It is true that Apache::Registry and co. help bridge the gap, but there are still things to watch out for even then.

If it's an API, I'd not make one module per function, if by function you mean a call (e.g., fork() is a function in the Unix kernel API). Instead, I'd group them by functionality (as in OS/2 - VIO, KBD, DOS, ...). So one module might handle customer accounts, another handle news items, etc. You probably want to analyse your application and do some redesign work at a basic level to take advantage of mod_perl. >My second question pertains to Apache::DBI.

Re: where to report apache::session 1.53 bug ?
in Apache::Session ver 1.53
BUG :
1. Flex , using Apache::Session::File
bug in Apache::Session
TIEHASH method for validate attribute in line 379 :
&{$self->{validate}}($self);
I am just commented this to get by pass the error !
this is below sample of code that cause error :
( Would be in the below of this email )
and error that is shown :
Global data is not accessible : Can't use string ("") as a subroutine ref
while "strict refs" in use at
/usr/lib/perl5/site_perl/5.005/Apache/Session.pm line 379
2. Apache::Session::Lock::File , clean method got bug in Line 136 !
it is written :
# This would be imposible to clean out lock file that is older than
second !!!
if ((stat($dir.'/'.$file))[8] - $now >= $time)
# bla bla bla
}
it suppose to be :
if ( $now - (stat($dir.'/'.$file))[8] >= $time) {
# bla bla bla
}
CONFIRMATION : ( I am not sure)
1. Apache::Session::Store::File , "seem" doesn't implement locking method
like flock in Apache::Session::Lock::File
when doing "update" an "reading"
How to handle with user that is "opening another browser new windows" and do
the same update ( concurency problem ) !
NB : I maybe wrong in this because I don't read all the source code
Question : I just need to confirm is Apache::Session::File is safe in
concurency problem above ?
SUGGESTION :
1. Apache::Session should implement clean method just like in
Apache::Session::Lock::File, but this time is clean method for "unused
session data"
Because lot of people when doing shopping cart or login session usually
don't
do "sign out" or something like that
it means impossible to do 'tied(%obj)->delete;' normally in program which
cause session data file like '7bf6117c473f77e791eb33213012d538' still left
in
/tmp/sessiondata !!
this means :
a. wasting space
b. slowing down processing in Apache::Session::File etc
I suggest name of method like 'clean_unused_data'
QUESTION :
1. how to implement suggestion number 1 in Apache::Session::File ?
because I so need this feature immediately ?
can you give me a quick code for this ?
or is it safe just doing this code ?
sub clean_unused_data {
my $dir = shift;
my $time = shift;
my $now = time();
opendir(DIR, $dir) || die $!;
my @files = readdir(DIR);
foreach my $file (@files) {
if ($file =~ /^[a-fA-F0-9]+$/) {
if ( $now - (stat($dir.'/'.$file))[8] >= $time) {
unlink($dir.'/'.$file) || next;
}
}
}
}

API Design Question
Hello all, I have an CGI based HTTP API (in Perl) to a database and I am now going to port to mod_perl. I am new to this kind of programming and I have a couple of questions. The platform is Linux. My first thought is to break the API up so that there is a module per API call (there are some 70 calls in the API). My reasoning is that I can modify existing calls and add new ones without affecting everything else. Does this make sense or is it better to have the API as one large program as I have it now? My second question pertains to Apache::DBI. I will ask it here but if there is a better forum to ask it please let me know and I will ask it there. I want to use Apache::DBI in order to cache database connections. If I understand everything that I have read so far (and that might be a big if) the various modules should share the same database connections while running on the same Apache server. Is this correct? I.e. if the API functions 'foo' and 'bar' have both been loaded into the same instance of Apache and both use Apache::DBI then they will share the same database connection. Thanks.
