Re: [OT] Design Patterns in mod_perl apps?
I would like to close this thread with LOTS of THANK YOUS to Gunther who gave me tons of very valuable information on the subject. I am still in the process of digging my way through design patterns, but still at the 'huh?' stage but am optimistic that very soon will have the 'Aha!' as the intro to the book says :) hint to perl/oop gurus (Damian, if you are listening): Time is ripe for a modern design patterns in perl book /hint best, bakki Gunther Birznieks wrote: The download link may be old. You might want to go to the extropiaperl project on SourceForge and get latest code using anonymous CVS. Also, in the last 2 months we really revamped the architecture to change from a central control loop to action handlers where a stream of action objects where the application is defined by the order and process through which the action handlers get processed. This is similar to the Struts project for the Java Servlet API on java.apache.org. It turns out to be a fairly powerful model that has increased our productivity even more. In addition, Webware will give me some real world apps to look at to get a sense of how CoR, flyweight etc are implemented, especially in Perl. This is right on the money as far as what I am trying to learn. That was part of our intention. We didn't really spend a LOT of time on design patterns, but certainly they had a strong influence. There have been tons of articles and books on Design Patterns since GoF Any specific web design patterns book you would recommend? If i was back home in the USA I could probably give you quite a few. As it is, I am afraid that I've just relying on articles here and there in the last 2 years because I never took my entire library with me when I moved to London and then to Singapore... I've been traveling more lightweight. GoF did not introduce Model-View-Controller architecture. But it is discussed in Wiley's "A System of Patterns: Pattern-Oriented Software Architecture". I think Addison-Wesley has a series of books based on the Pattern Languages symposia over the last many years which gives an overview. Any article by PJ Plauger I've ever read is pretty good. You can look a lot of his stuff up by searching the web for his name plus patterns. Malveau and Mowbray's CORBA Design Patterns is a really good book for anyone doing distributed programming even if it's not CORBA. The Pattern Almanac from Addison-Wesley doesn't really describe patterns all that well but it does provide a lot of references to existing works and provides very very short but easy to read summaries of many patterns out there. The cool thing about the Pattern Almanac is that it has a lot of patterns that are not idomatic to OO but apply to many situations. For example, it even has a section on "Patterns for Designing in Teams"... which include Multiple Competing Designs, Decision Document, Creator-Reviewer, Master-Journeyman, and Ad-Hoc Corrections Thanks, Gunther -- _ _ .-. |M|S| Bakki Kudva |D|_|a|y| Navaco |o|m|n|s|\420 Pasadena Drive |c|e|a|t| \\ Erie, PA 16505-1037 |u|n|g|e| \\ http://www.navaco.com/ | |T|e|m| \ ph: 814-833-2592 "" fax:603-947-5747 e-Docs
Apache::Session::File
Hello,
I ma trying to use this module to store persident data on file
on win32 environment.
I use the code:
use Apache;
use Apache::Session::File;
use CGI qw/:standard/;
use CGI::Carp qw(fatalsToBrowser);
print header();
print start_html;
my %global_data;
eval {
tie %global_data, 'Apache::Session::File', 1,
{Directory = '/temp/sessiondata'};
};
if ($@) {
die "Global data is not accessible: $@";
}
print "hello";
print end_html;
I get error in apache logs :
Can't locate IPC/SysV.pm in @INC
do I need the IPC/SysV.pm module?
I have searched the documentation but i don't see a simple clear example
to do this.
Can you help please?
Thanks
RE: Doh; StatINC can't find files?
Hi,
do you have a startup.pl with something like
$ENV{MOD_PERL} or die "not running under mod_perl!";
use lib qw( /your-path-to-your-libs );
which is registred in your httpd.conf with something like
PerlRequire /etc/httpd/startup.pl
PerlInitHandler Apache::StatINC
PerlSetVar StatINC_UndefOnReload On
PerlSetVar StatINC_Debug 1
or did you add your lib path directly in httpd?
you have to set your (%INC) BEFORE running your scripts.
regards,
Harald

Subject: Doh; StatINC can't find files?
Hi folks,
Maybe I'm just rusty after 8 months off, but my StatINC can't find files
that exist on the system:
wm ~tail ~wm/wm/logs/errorlog
Apache::StatINC: Can't locate /home/wm/wm/perl/WM/Class.pm
wm ~perl -e '$file="/home/wm/wm/perl/WM/Class.pm"; $mtime = (stat
$file)[9]; warn $mtime;'
963258607 at -e line 1.
I thought it might be perms, but:
wm ~ls -la /home/wm/wm/perl/WM/Class.pm
-rwxrwxr-x1 wm wm 10357 Jul 20 2000
/home/wm/wm/perl/WM/Class.pm
And the same thing happens with Apache::Reload ...
I'm sure I'm missing something obvious; any clues?
Thanks

Environnement stability and maturity
Hello. I'm about to give the kick-off of a new project and we want to start with current and to-date version of software. Will it be ok for production use to go with all-fresh version of the mod_perl environnement : apache 1.3.17, mod_perl 1.25, perl 5.6 ? I'm going with the latest version of Solaris (euh... what is it? I am the programmer on that, not the sysadmins... ;o) I'm on the impression from my reading of the list that there was some problems with perl 5.6 : am I wrong?

Extending the FancyIndexing description text ?
Hi, Could somebody give me a pointer in the right direction for manipulating the contents of index pages. I need a way to insert an href under the description column for each file in a directory, which is a link to an RDF search facility I'm creating, e.g. FileDescription --- foo.doca href='/perl/rdfsearch.pl/projects/docs/foo.doc'Resource info/a bar.html a href='/perl/rdfsearch.pl/projects/docs/bar.html'Resource info/a I need to pass in the search script the resource in question - via path_info seems easiest. I want the rest of the page to be the same as usual, with the icons mapped to file extensions/mime types etc. Before I jump in at the deep end has anybody done this kind of thing before... I took a quick look at Apache::AutoIndex but I couldn't see a way to add extra text for each entry in the directory. The alternative is to code a handler from scratch but it seems a shame when 90% of what I want is already provided. cheers Tim Fulcher

I've been quite happy with 5.6 in production for quite some time. I used the source provided by activestate because it includes a number of patches but now that 5.6.1rev2 is out it might be better. There are probably bugs, but I bumped into none (except perhaps one weird behaviour of the new warnings pragma that eventually went away and which I could never track down, perhaps it was me). Apache 1.3.14 and mod_perl 1.24_01 seem to be the usual near perfectly stable. -- robin b.

Repost with code: Newbie mysterious 500 error with PerlFixupHandlers
Sorry I forgot to include these files with the earlier message.
Does anyone have any clues with this problem.
I have searched the archives for internal server errors and
PerlFixupHandlers
and found no similar problems. Perhaps this is a mod_dir issue.

We are using
RedHat Linux apache 1.3.14 mod_perl_1.23_01
Our site is set up to generate pages using a templating system to add
custom headers footers and sidebars. As well we use .htaccess files to
further customize the subprocess_env.
We are using custom modules installed as PerlFixupHandlers both for
template generation and multilingual negotiation
Negotiation.pm handles lingual content negotiation. It determines
what version of the page to present based on the users preferred
variants and the available variants for that page.When the best match
is found, it
performs an internal redirect to that document.
Template.pm is installed as a fixup handler, and is controlled through
various PerlSetVar directives.
Basically, it determines what to include at the beginning and end of
the web page.
fixup sets the content handler for the request.
Also has two subroutines, handle_rec for static pages ,and handle_cgi
for scripts These allow the auto-inclusion of headers and footers of web
pages.
In httpd.conf

DirectoryIndex index.cgi index.html
PerlRequire /www/perl/libs/WRI/Template.pm
PerlRequire /www/perl/libs/WRI/Negotiation.pm
PerlFixupHandler WRI::Negotiation WRI::Template::fixup
---
These modules work 90% of the time
The problem occurs when a directory is requested, and served as a
negotiated document
and is passed to our content handler. (handle_cgi)
A save-as window pops up in the browser and Apache logs a 500
error. (The file it is trying to save is the standard 500 internal
error message.)
In the Template::fixup handler, the
document is being detected as a cgi-script, not a server-parsed
document. The 500 occurs because we are trying to execute a static
document or directory.
Template.pm
In run_cgi:
unless (open(CGI,'-|')) {
#don't need the writing handle to the pipe anymore
close(WR);
#make STDIN be the read handle of the pipe (so we can get
#POST information from Apache)
open(STDIN,'RD');
#Run in the directory of the file
$r-chdir_file($filename);
### This returns 500 when a directory or static file is negotiated ###
#Run the file
exec($filename) || return SERVER_ERROR;
}

-
My understanding is that when OK or DECLINED is returned from these
modules in the list of fixup handlers, control passes to the next,
and when DONE is returned, the remaining are
skipped mod_dir regains control and the next default file is requested
(index.cgi index.html)
Is this correct or is there something I am misunderstanding.
Request Outline
---
mod_dir sends directory request to Negotiation.pm
/products/student/calcwiz/
returns OK from Nego.pm
mod_dir then sends index.cgi - index.html
Nego.pm negotiates index.cgi and each of available variations
then index.html ..
when found most appropriate
Negotiating:
/products/student/calcwiz/index.en.html
Template.pm
handling request..
/products/student/calcwiz/index.en.html
Another Clue
This error recurs when the page is reloaded 25 - 30 times
MaxRequestsPerChild is 30
Could this be related to our problem.

you have to use a Perl block.
This might work :
PerlSetEnv SERVER_ROOT \

Apache::server_root_relative()
/Perl
But this seems so much easier :
Perl
$ENV{'SERVER_ROOT'} = Apache::server_root_relative()

I'll send it to you if you'd like, and then you could see if there are any extras in it that would help your patch. I did patch all the documentation in our version to include the new option, so that might be a useful addition to yours. - Perrin

Oops, yes, you could use Devel::StackTrace or just use Carp::croak. Devel::StackTrace gives you a finer grained access to the stack trace (you can examine it frame by frame) rather than just dumping a string. For the purposes of dumping a trace to a log, either one will work just fine. -dave /*== www.urth.org We await the New Sun ==*/
Re: Environnement stability and maturity
Hello, RBI've been quite happy with 5.6 in production for quite some time. I used RBthe source provided by activestate because it includes a number of RBpatches but now that 5.6.1rev2 is out it might be better. What is the "official" home of 5.6.1rev2? I can't seem to locate it on CPAN anywhere. The p5p summary on http://www.perl.com/ seems to be under the impression that 5.6.1 isn't going to be out for a while. I remember seeing a pointer to one of the very early patches, but I can't seem to find it again.

mod_perl failing to interpret bytecode modules
Arguments about open source aside, I have been asked to convert our commercial mod_perl modules into bytecode. I have tried to do this but have encountered various problems as described below. I have also browsed the previous discussion threads on this topic with interest, but they are quite old, and it is not clear that anyone has actually got this working. Any feedback on this issue would be much appreciated. I need to know whether this is a "show stopper" or just something I am doing wrongly. Thanks, Mark Twose (Senior Software Consultant) My experience is as follows: I am using Apache 1.3.12 and Mod Perl 1.24.01 that I have built on Solaris 2.6. Having sucessfully converted and run a simple stand alone perl script I decided to try a simple mod_perl based web page (Hello.pm) attached: (See attached file: Hello.pm) I can successfully convert Apache/Hello.pm into bytcode by doing the following: perlcc -b -o Hello_bc.pm Hello.pm mv Hello.pm Hello_txt.pm cp Hello_bc.pm Hello.pm I then registered this in httpd.conf with the following directives: Location /hello/friend SetHandler perl-script PerlHandler Apache::Hello /Location When I access hello/friend from a browser the following error is logged in apache/logs/error_log: [Mon Feb 5 13:13:41 2001] [notice] child pid 1967 exit signal Bus Error (10) I have also tried encoding Hello.pm using the example "Rot13" source filter. This also fails to interpret under mod_perl. I then tried bytecoding an Apache Perl Module. I pre-loaded this with the following directive: PerlModule Apache::MyModule Apache core dumped on startup as follows: (gdb) where #0 0xef563a08 in byteloader_filter () from /usr/local/lib/perl5/5.6.0/sun4-solaris/auto/ByteLoader/ByteLoader.so #1 0xc7b50 in S_filter_gets () #2 0xc9480 in Perl_yylex () #3 0xdcf98 in Perl_yyparse () #4 0x14b544 in S_doeval () #5 0x14ce9c in Perl_pp_require () #6 0x111b88 in Perl_runops_standard () #7 0xb9670 in perl_eval_sv () #8 0x3ec88 in perl_require_module () #9 0x392e4 in perl_cmd_module () #10 0x82fec in invoke_cmd () #11 0x83680 in ap_handle_command () #12 0x83760 in ap_srm_command_loop () #13 0x83ec4 in ap_process_resource_config () #14 0x84b00 in ap_read_config () #15 0x93428 in main () I am guessing that the problem is related to the perl "eval" function. I have tried running bytecode ( source filtered) modules using "eval" directly from Perl and this also failed. Perhaps this is a limitation of PERL, not mod_perl? Hello.pm
How Stable and The Perfect Combination
Hi People! I have some questions about the usage of mod_perl in an almost embedded environment. We want to put Apache with mod_perl in a FreeBSD 4.2 powered server appliance that has almost no remote admin capabilities. Things need to keep running for months. Our concern is the stability of mod_perl. My last mod_perl project was 1.5 years ago on HP/UX and I remember we had lots of weird crashes and memory leaks. How has this changed? I see that the current version of mod_perl is 1.25, is this considered stable? Is 1.25 with Perl 5.005_03 and Apache 1.3.17 a good proven combination? if not, which versions should I use? Thanks!

Apache::ASP Best Language to use?
Currently the company I work for is using ASP code running on Windows servers. We'd like to run a web server that isn't microsoft based for obvious reasons. We don't have so much ASP code, so it would be possible to scrap it and start over. What would you guys suggest as the best option: 1. Porting our ASP code to Apache::ASP and continue development in ASP 2. Doing new development in JSP 3. Doing new development in CGI 4.

There is a project somewhere that implements the frontpage extensions as a Perl CGI script - how would people feel about a pure mod_perl version?

[JOB SEEKER] Full Time Telecommuting
Hi all... Well, I think the time has come for me to leave my current position. Most of my formal work stuff for the past year is covered my NDAs, but a brief resume can be seen at http://resumes.dice.com/gost_guru And, of course, there is always my CPAN stuff and list postings to serve as references :) I live outside Philadelphia, PA and really cannot relocate, so telecommuting is preferred. I will, however, consider occasional travel to client sites if the job is a good fit. Anyway, hope this wasn't too obtrusive... --Geoff __ Get personalized email addresses from Yahoo!

SQL log analyzer for Apache::DBILogger

RE: server_root question...
Interesting, I tried the following in perl.conf:
PerlRequire conf/startup.pl
PerlFreshRestartOn
PerlSetEnv MOD_PERL_TRACE all
#Directory Handlers
#--
Directory /perl
AllowOverride None
Options +ExecCGI
SetHandler perl-script
PerlHandler Apache::Registry
PerlSendHeader On
/Directory
Directory ~ "^/(cgi-bin|htdocs|perl)$"
PerlAccessHandler Apache::GateKeeper
ErrorDocument 403 /index.html
Files ~ "/(index\.html|login\.cgi)$"
PerlAccessHandler Apache::OK
/Files
/Directory
Perl
$ENV{'SERVER_ROOT'} = Apache::server_root_relative();
/Perl
but, the Perl Block Directive issues this error on restart:
Syntax error on line 26 of /home/dvlp/jcrotty/apache/conf/perl.conf:

Any ideas would be greatly appreciated.

Subject: RE: server_root question...
If you want to use a perl function ( Apache::server_root_relative() ) then
you have to use a Perl block.
This might work :
PerlSetEnv SERVER_ROOT \
Perl
Apache::server_root_relative()
/Perl
But this seems so much easier :
Perl
$ENV{'SERVER_ROOT'} = Apache::server_root_relative()
/Perl
Maybe its too early or whatever. How would you go about setting
$ENV{SERVER_ROOT} without using Perl. I was trying
PerlSetEnv SERVER_ROOT Apache::server_root_relative()
in perl.conf, but no go. Any ideas?

Re: Apache::Session::File
You need to change the locking mechanism on Win32 to not use IPC. I believe
there are examples for using Flock based locking but am not sure.
If you are using win32 mod_perl, locking is irrelevant anyway because all
requests are serialized through one engine.
