Re: decline and fall of modperl? (my last post on this subject)
Please do not reply to my comments. I think it's time to close this and move on. Ok, my personal summary on this topic: 1. The fact that so many people (including lurkers) responded to this email suggests that it is a subject that's important to them - be it personal, professional, or academic. Conclusion: It would be unwise to for anyone to attempt to conclude a question like this with short answers. The variety of the responses also suggests that Perl is used by many for many intents and purposes. 2. There were many good and interesting points brought up on the relavancy of Perl in today's context. There were anecdotes, personal experiences etc contributed by everyone. Conclusion: Not all points will be relavant in the context of every developer; business environments are not hetrogeneous in all parts of the world. Perl needs to present a 'face' that will work in each of these environments if it wants to remain relavant there. Generally it is doing a fairly good job in that aspect. 3. Throughout the discussion everyone remained reasonable rational, and attempt to comment on facts and personal beliefs. Conclusion: Compared to some other mailing lists I subscribe to, we Perlites are a fairly level headed bunch. Let's give ourselves a pat on the back on this. And stay that way please. Let's move on with new topics of interest please.

Octavian Rasnita wrote: It seems that Perl is beaten by this new atitude, and the fact that it is a better language doesn't help too much. Haven't we all learnt from Bush, that the best people don't always make President? If the program is hard enough protected, most users won't be able to get its clear source code, so we can say that it is protected. But if we protect it by just a licence, nothing would stop the user to sell it to someone else (theoreticly, of course, not that this thing really happends). I think we should just agree that there are 2 styles of businesses: 1. Linux-style: devalue the privacy of your source code. Let people buy your product because of the code quality, and the ability to make minor changes on your own responsibility. 2. Windows-style: your code is mystery, but your program works anyway and your support is good. And that's good enough for people to buy your product. Using Perl doesn't mean we must adopt Linux-style biz. There are other environments, which thrive on Windows-style biz. Luckily Perl does support this to some extend.
Re: decline and fall of modperl?
Rolf Banting wrote: 1. Perl supports more programming paradigms than Java. Agreed. The problem is with perception. People identify Perl as a procedural language, and strongly typed languages (ie C#, Java) as modern languages enforcing modern concepts. We all know that's isn't entirely true of course. But that's the perception. 2. You write fewer lines of perl to get things done than you do in Java. I probably should have elaborated on this point. By way of 'minimise the learning curve', I mean an elaborate IDE which helps the user focus on key algorithms. Without the IDE, I would think programming Java is more unwieldy than Perl. But suddenly with Eclipse, it's all about click here and there, and having the system figure out some of the minor stuff for you. Point 3 does scream Java but take a look at this: I could be mistaken here, since I'm only writing from the perspective of my local context. It's like the old buy-IBM mentality: nobody gets fired for buying IBM and have it fail. Here, no lecturer will be blamed if he were to train students on VB.NET/ Java, only to see the language fall out of favour.
Re: decline and fall of modperl?
Octavian Râsnita wrote: 1. I don't know what it means that perl supports more paradigms than Java, but I know that the Java / C# OOP style is usually considered a much complete and better standard than one used by Perl. Java / DotNet support interfaces, so the classes they create respect the contracts better, while in perl world, the programmer is free, and nobody points a shotgun to him in order to force him to do it. Perl is a funny animal. It doesn't have a formal support for interfaces, but it suppports multiple class inheritance. It also has - for a very long time now - support for closures, which I find very interesting (few Java developers even heard of it). Agreeably, Perl is neutral enough to let bad boys ignore the 'contracts' aka interfaces. But I would say that it's more of a feature (some would use the word 'beauty'). I do acknowledge there's some pain in this philosophy though. There's always a workaround to enforce things if you want it to. One of the things I really like about Perl's classes is how there is more than 1 way to mark a class: 1. As a reference to a hash 2. As a reference to a scalar 3. I think there's more, but I can't remember offhand. Each of them has its own advantages. Java and C# uses a dot notation for separating the classes when using the OOP style, and even Template-Toolkit uses it, but perl uses something else. There's a worse one I hear about. PHP is going to use '/'! Personally, I would think little whether the language uses . or ::. It's like saying cars in Japanese adverts are white, and so are Korean. So Chinese cars should be so. As long as they dun use some garish colour, we should all hold hands and sing Auld Lang Syne. And anyway, for the beginners, this is not a big problem. The biggest problem is that perl is harder to learn. The programmers might want to learn a language for a year, and get a job, and after this they hope that they will find time to learn the chosen language better while they have a job. Human mentality will usually opt for the path of least resistance. In other words, if they learn Java today, they will look for a bigger Java job tomorrow. Only bosses have the power to wave their hands and say 'You do not want Java. You want to master Perl'. We could say that perl would be really great for these days if we could say about it something like: - It is the most easy to learn language even by the most stupid programmers. They have already done that. It's called Visual Basic. :) - It can create portable programs that can run everywhere, under Windows, Mac, Linux, shared hosting web sites that don't offer root and shell access... Lose out to expensive marketing folks from Java. - The source code of the programs can be hidden. Tough argument. No dynamic language can boast the same ease of 'hidden' codes like Java/ C#. There's hope via Komodo though. - There are very many recent books that teach Perl. Not recent enough. Wrox releases new C# books as soon as Microsoft finds a new reason to launch a new .Net framework. - Perl is chosen by bigger companies like IBM, Oracle, Microsoft, Sun, Yahoo, Google, SAP. And Blackboard too! - There are important other software made in Perl which are used much these days, like a mailing list manager, a web server, financial charting software, stock exchange trading applications, etc. I know it works, but the exe file created is huge, compared to a C# executable. It also takes longer to execute too. The truth of the matter is: the bulk of C#'s libraries are happily hidden away in the Windows folder. We need to find a way to do the same for Perl, like a Perl 5.10 Runtime.

They like to program, then they realise that being a programmer means been strangled by middle management. Then they start to aspire to BE the middle management (if not higher). The problem in a way is not really about interest, but rather the fact that s/w dev is commoditised to a higher degree, more than other engineering positions. It's a nasty feeling when your job is constantly challenged by half-priced (in some places it's quarter-priced) off-shore devs. Yes we all know the pain in outsourcing. But tell that to managers who spend more time cutting costs than increasing revenue to increase bottom line. Who cares? Hiding source code is valueless.

It's called ShanZai; loosely translating to 'Mountain Fortress'. And they're damn proud of it. Being able to analyze and apply a direct fix to code that is malfunctioning is of such high value that making it impossible is a serious handicap. Agreed. Assuming you have the pro dev in your team. I keep thinking they're ashamed of their code thats why they want to hide it. Now you're just getting personal... :)
encrypting perl

Business people love the idea of their intellectual property (IP) being protected by way of code encryption. Try telling them their money-making code is 'in the open, but everyone's doing it too'. Not exactly a warm fuzzy feeling. This topic has been resurfaced from time to time. I think the bottom line is: there is no supported form of code encryption for Perl. Some people try to partially compile the code into bytecode, and distribute with that. But I don't think it's officially supported. The forward step in this may lie with Perl6. Unfortunately while Parrot 1.0 has JUST been launched, Perl6 isn't, and it'd take quite a while before we get there. It's still NOT encoded, just compiled into a more cryptic form, just like Java and the rest.

David Ihnen wrote: I think you've got it right there. We've got to get perl taught in schools. That means perl experts need to be in teaching. And I have a suspicion that perl doesn't appeal to the pure computer scientist very well - these are the people who invented hard typed languages, after all. In the academia the general directive in choosing a language would be something to this effect: 1. teach modern language concepts, such as OO 2. minimise the learning curve by way of something easy to teach, easy to learn without having to figure out all the details of programming 3. introduce the students to a language that will make them attractive to the general market You probably have a feel why Perl isn't a strong choice given these objectives. Perl was popular in the days when the people who go into software courses do it for the sake of pure interest. These are the people who are contented with Emacs or VIM, as long as they get to work with the codes. Half of today's CompSci students are people who stumble in because they haven't figured things out in life. The problem is made worse by Visual Studio and Eclipse. I remember how Java was a painful experience before someone finally put up a IDE that aids code visualisation and object description. My personal belief is that Perl MUST move with the times. It's an incredibly uphill task to change the market's mindset without a commercial budget. I place my bets on Perl6. It's regrettably a slow process, but it's the only sexy thing available on hand. Pay them to do it in perl, and after they get through the learning curve they'll probably be much happier with it. Half the developers aren't the type who can appreciate a good language. They can develop intensively for 5 years and they STILL haven't figured out what is Regex. Trust me on this! Who cares? Hiding source code is valueless. You haven't met the China folks have you? :) There's outright protection, there's deterrance, and there's leaving the door open for every bad boy to muck it up.

I tried to recover an old perl app packaged by ActivePerl some time back. It was impossible to do this, and the good guys at AP verified my pain. If anything I'd say that I feel confident my (AP-packaged) products will not fare any worse than any commercial Java/ .Net executables in the wild.
Re: Fw: Re: decline and fall of modperl?
In my humble opinion the perl community needs to embrace the concept
of self propagation. For the most part perl/oo perl/mod_perl
developers are self taught. Junior or mid level talent (a majority
of the talent pool) is passed over as not enough experience.
It is interesting for me to hear that developed countries are also
having difficulties finding Perl-savvy developers out of the varsities.
I do agree that not being able to find 'Perl-ready' graduates should not
be a deterrant - I myself being a brainwashed Java advocate for a while
before stumbling onto Perl.
In my local context, deciding on Perl/ PHP/ Ruby requires a great deal
of support on the business side:
1. The average turnover rate is about 3 years. That means every 3 years
you have to retrain a new guy to take over relatively established code.
Since we have to accept the fact that it's extremely difficult to hire
an experienced Perl dev, the quality and experience of the dev team
halts at about 5-6 years.
- New strategies will be have to be formed to distinguish the core
engine from the customisable. The company must recognise the business
viability in retaining the core team, while accepting that the mediocre
will move on in time. The core team itself has to develop good mentoring
and training skills to induct the new intake.
2. Selling to clients who only understand .NET and Java ('modern'
languages) will be a challenge. Governments and large enterprises
generally (and mistakeably) associate other languages to be an
investment risk.
- Nobody asks about the innards of an appliance or a product. As long as
it runs, runs well and affordably, it's good enough.
Sounds reasonable enough, but it's a lot work to get there...

Is there a generic method so that given any uri as a parameter, the

I'm not sure if that's the one. From the docs (your ref link):
filename
Get/set the filename on disk corresponding to this response (the result
of the URI -- filename translation).
Sounds like this method assigns a file to the uri instead.

Hi all, I'm testing the latest mp2 stack on FreeBSD 7. While everything installs ok, I'm having difficulties locating the Apache2::Cookie module. I understand Apache2::Cookie is part of the libapreq2 package. I installed that via ports, and the installation did not report errors. The module mod_apreq2.so loaded quite happily. But when I tried to 'use Apache2::Cookie' Apache22 throws out the error in http-error.log: Can't locate Apache2/Cookie.pm in @INC (@INC contains: /usr/local/lib/perl5/5.8.8/BSDPAN /usr/local/lib/perl5/site_perl/5.8.8/mach /usr/local/lib/perl5/site_perl/5.8.8 /usr/local/lib/perl5/site_perl /usr/local/lib/perl5/5.8.8/mach /usr/local/lib/perl5/5.8.8 . /usr/local) I did a 'find / -name *ookie* -print' but I can't find Cookie.pm.

Hi all, Recently started testing the a/m stack. Happy to report: so far so good: 1. Apache can be restarted via ApacheMonitor.exe 2. Works with libapeq2.6.3 3. Survives multiple restarts 4. Works with Apache2::Reload Disclaimer: I'm not hard-core mp2, so the tests are wy surface-grade . A point to note: Apache2::Reload is not available as part of the ppd installs. However I was able to simply copy out the relevant folders in the source to Perl/site/lib/, and it works w/o further intervention.

Re: mod_perl2 start one script twice
It's quite simple really. You're running 2 instances of the script. To retain the value of $counter, read up the mod_perl documentation for tips. CthuMP wrote: I have follow simple script: !#/usr/bin/perl print Content-Type: text/html\n\n; print Counter: . (++$counter) . \n; print time(), \n; sleep(20); print time(), \n; Starting that script twice in two different browser windows gives me same results. In second window I start script after some period (about 10 seconds) after first script started. First and Second scripts ends at the same time. So, I misunderrstand, why results are same? As I see it, apache must give work to second child processes for second request (because first busy). And scripts must end works in different time (first script in 10 seconds before second) and give different results (same counter result, but different times). Even if script runs sequentially for each request, results will difference and second script ends after 30 seconds (10 remained for 1st script and 20 for 2nd). But it is not! If I copy script and run two same scripts with different names it works fine. Second question about childs. I not fully understand, how childs work. One child can handle only one script? It's important, because if one child can handle different scripts, than module global variables saves their values between different script calls. For example, if script1 and script2 uses module My::TestPackage, first script sets $My::TestPackage::variable = 123, then script2, after it request, will see in $My::TestPackage::variable value 123, but I haven't seen mention about that situation in official documentations.
Re: Windows settings cause crash (originally: FAIL!!!)
You may want to try 2 options:
1. Use an older version of the Apache build like 2.2.6. It has been
known to be fairly stable.
2. Try the build from ApacheLounge. It's generally not favoured, but it
seems to handle some things better.

hello,
I'm trying to get mod_perl running under Windows. I used the latest
perl from ActiveState (5.8.8.824), Apache 2.2.9 from apache.org, and
mod_perl 2.0.4, installed from ppm. When I ran a simple perl script and
had 20 simulated users hitting the page, it eventually said 'Out of
memory!' and restarted with a status of 0. The second time it happened,
it tried to restart, but couldn't. Does anyone know if these versions
actually work together? If they do, any thoughts on what could be wrong?
code:
use strict;
my $err = 'eh';
my $body;
my $errstr = int(rand(2));
print 'Content-type: text/html','\n\n',$err,':
',$errstr,'\nSERVER_ADDR: ',($ENV{'SERVER_ADDR'} ||
$ENV{'COMPUTERNAME'}),'\n';
if($errstr){
$errstr =~ s/\://g;
$errstr =~ s/\n/ /g;
$body = 'Error Text: ',$errstr,'\n';
}
print '\n';
print scalar(localtime());
if($body){ $body =~ s/\n//g; }
print $body;

The advantage of GD::Graph is that it'd likely be rendered as a JPEG/ GIF, and that's something you can download and reuse in an executive chart.

Re: refactoring client's decision
Creating packages with the same name for multiple sites is generally a recipe for confusion. Following what Michael Peters said, the better way will be to create a properly namespaced package instead. But in the event that the right thing cannot be done, you can consider creating a new interpreter for each site with the Options +Parent config in Apache. Do note that this solution may be memory intensive, and will not scale as broadly as a shared interpreter. IMHO, try to get things right the first time. It's usually more painful to revisit a quick-fix. Marc Lambrichs wrote: I've taken over some code for a client. They've built a framework that used to run under mod_perl and changed it later, because of problems they had - what problems remains unknown - to cgi. Ofcourse I'm curious why they changed it. Here's my view: they create a parent App::Handler and in every virtual host they create a Site::Handler which has App::Handler as base. My first guess is that under mod_perl you don't know which Site::Handler will be called. Ofcourse, at first, the handler you're actually pointing to will be called, but if you change the request to another virtualhost, the wrong handler will be called. This would explain why it's running perfectly under cgi, because in every script call the correct lib path is defined. So, my first question is: am I right? Secondly, what if we're running the cgi under speedycgi? Thx, Marc

Re: @inc ithreads virtual server +parent
Dylan, Let's see: you have a client base who likes a staging-production development scenario. There's a few ways you can play it out: 1. Different client, different code base You use 2 machines: 1 for staging and the other for production. Set them up exactly the same. Run your VirtualHost for each client. Since it's a unique code base for each client, there is no fear of code contanimation. Life is quite simple here. 2. Different client, same code base You're probably setting up a product for PoC (hence the same code base), with a slightly different config for each client. a. Turning on +Parent should do the trick (with ithreads), but you need to test it out a bit to make sure you got it right. b. Since it's staging anyway, there's no need to spawn all the child threads/ processes. In which case you can create multiple instances of Apache for each client (perhaps even 1 for staging and another for production) with a minimal thread/ process count to save memory/ cpu. This method allows you to use either ithreads (which is only encouraged for Win32 platform) or prefork (Linux). Having said that, production servers should ideally be free of unstable code. So putting staging stuff in the same box is not advised, unless your clients are very forgiving. :) Dylan Tynan wrote: I’m looking at the information in mod_perl 2 User’s Guide (and online) about using VirtualHost and +Parent, with an ithreads-enabled Perl, in order to be able to modify @inc by virtualserver. On my system I basically have that setup, and have tried it, and it seems to work fine (I tried it with prefork, though that appears not to matter except for the inefficiency of course). I’m wondering what would happen if I –didn’t—have an ithreads-enabled Perl, but still set up the httpd.conf with the virtual-host/+parent stanzas? Will it fail on startup with an error about +parent being unsupported or some other error? Or does it run fine but I end up with a shared @inc across all virtual servers perhaps? .. I have a somewhat limited customer set and each customer will probably run a test production setup, with mostly the same code in each environment (thus @inc conflicts). I’m wondering what, if anything, they might see…. I take it the only real way around the above situation is either to use an ithreads-enabled Perl or to run separate apaches… is there some other way? Thanks! Dylan
Re: Question about open()
I do keep my templates in other directories also.
1. If your directories are relative to the document root, and you can
take advantage of this fact by rendering a variable to remember the
template path.
2. If your template directories have nothing in common with the document
root, then you can set the variable via SetPerlVar within http.conf.
That takes the 'hard' out of your code. :)

Re: Apache 2.2.6, mod_perl 2.0.3 msvcrt.dll start problem
Randy, I think characterizing the ASF binaries as unreliable with mod_perl is misleading - there were some recent problems with restarts, etc. on Win32 that have been looked into and addressed for the 2.2.8 release. The intent of my earlier response was not to undermine the quality of the ASF builds. I have been relying on the ASF binaries since 1.3 (even though it was not recommended for Windows). And it's only in the recent months that I have come to depend on another source until some of my key needs (on the binaries) are resolved. So please take it as just a layman sharing his experience and resolution on the problems. Moving forward, I do see that there's some conversation about recompiling modperl based on the newer releases of ActivePerl. That's a very encouraging move. - As you say, the ApacheLounge binaries use a different compiler version which may in itself introduce some problems. Agreed. To date I still don't know what mess I've gotten myself into by using this hybrid stack. It's still looking good and I'm crossing my fingers. Maybe it's finally my lucky year... - As well, the latest ApacheLounge binary distribution contains some changes: http://www.apachelounge.com/forum/viewtopic.php?p=9752 from the official ASF 2.2.8 sources, which isn't apparent from the title Apache 2.2.8 available on http://www.apachelounge.com/ Noted. I think it's fair to say the mod_perl developers will only provide support for official ASF versions of Apache. Since mod_perl is an ASF project, I guess it can't be helped. Personally I do applaud the 2nd take on the Win32 binaries that AL took. Having said that, at the end of the day everyone lives and dies with the ASF development.
Writing a startup module for modperl in Win32
Hi all, I've done some refactoring recently on my mp2 app (on Win32), and succeeded in resolving the annoying startup issue (basically, does not start up well). I've documented my experience in the following url: http://jhfoo.multiply.com/journal/item/163/Writing_a_startup_module_for_modperl_in_Win32_Part_1 But for those who just want to know what did the trick, I included a simple mechanism to prevent the crashing during file IO: use Thread::Semaphore; $MyLib::sem = Thread::Semaphore-new if (!defined($MyLib::sem)); $MyLib::sem-down; # do stuff here $MyLib::sem-up; Hope this helps :
Re: Apache 2.2.6, mod_perl 2.0.3 msvcrt.dll start problem
I know. ApacheLounge uses a different (newer) compiler, and the implications can be quite risky. I've started on this path since the earlier 2.2.x when modperl on the ASF binaries has been unreliable, and support on the mailing list confirmed my experience more than resolved it.

Re: AP2.2.7 + MP2.0.3 on Win32
After some investigation, I realise that it's modperl on Win32 is still more stable on 2.2.4 (ApacheLounge). Some layman findings: 1. Apache2::Reload can cause the startup to crash easily. eg. when you load HTML::Template 2. Fault report on Events is like this: Faulting application httpd.exe, version 2.2.7.0, faulting module msvcrt.dll, version 7.0.3790.3959, fault address 0x00037e23. My interpretation is that it's to do with incompatibilities with the compiler used by ApacheLounge. 3. I tried MP2 on ASF's binary of 2.2.7, with similar results esp. on Apache2::Reload. I've swung back to 2.2.4 and things are much happier now.

Re: Caching Packaging
If you're running your scripts in Apache2::Registry, your scripts are compiled on first go, and remain in memory subsequently. When your script changes, the change should be detected, and recompilation is automatic. IMHO this is a real time saver as development goes. do() is bad for speed optimisation as it's treated as a system call. What you want instead is to modify your header.pl into a package, and have your scripts call functions in the package. Minimise exec() calls as well (ideally you should not use it at all). brett lee wrote: Hello - Am executing several CGI scripts under mod_perl using Apache::Registry (I hope that terminology is correct). As I understand it, the scripts get cached in each httpd thread the first time that thread executes them. Is this correct? So when I change a script, do I need to restart Apache, flush the cache somehow, or does each thread automagically replace the cached copy with the updated one from disk? Basic stuff, but I'm curious... The main focus of my writing today is to get some guidance on the proper direction to take for this project. Currently, each of the CGI scripts I have sources the same set of files (one for the header, another for the footer, etc). Per the above questions, I don't how the mod_perl processes work to keep everything in sync but I can only imagine that having each of my CGI scripts source the same files from disk has to be grossly inefficient. Am thinking that all these external scripts should be packaged up together into mod_perl somehow, but I don't know where I should be looking. Can someone shed some light? In doing so, one possible constraint is that I'm also executing the same external scripts from several SHTML files. The CGI scripts call the filesystem based subroutines after initially sourcing them with 'do ./header.pl' whereas the SHTML files pass in a go argument to 'header.pl' to actually fire up the subroutine. This allows me to execute them immediately using SHTML 'exec' calls and 'on demand' from the CGI scripts. Thanks in advance for your guidance / direction. -Brett Never miss a thing.

Re: Theory and practice of mod_perl win32
Thinking from the perspective of the developer who tries very hard to avoid dealing with C/C++, can the ApacheLounge patches and compilation do the trick? Caveat: have not read the dialog on the mailing list described. William A. Rowe, Jr. wrote: Anyone following the dialog on [EMAIL PROTECTED] and [EMAIL PROTECTED] is already aware of problems users are hitting with httpd 2.2.7 and modperl. Here's my current theory in search of a sanity check. There are two general classes of 'major issues' that we are going to encounter with msvc interop between httpd, perl and modperl. * malloc'ator flaws; memory allocated in one components heap and later freed in another * stdio/posix io handles. These don't map between one and another. To solve the first issue, there is only one solution. Because perl and modperl are both managing perl memory allocate/free, those must be compiled against the same msvc lib. That means using perl's compile hinting. In practice, this may be the difference between a user who says yup, works for me and those who fail utterly. Likewise they should use an openssl etc which are compiled against perl's choice, or that blows up for certain openssl-oriented xs's which have the same tight integration. To solve the second issue, I think we can hack it. What if modperl verified, and reinitialized if necessary, the stdio handles associated with its msvcrt during the register_hooks phase and again during the open_logs hook (run as 'very last'). This should ensure the stdio handles are legit even if httpd started under one msvcr, while perl and modperl are running under another. Just a thought, I have a bunch on my plate but I wanted to float a possible solution. Bill
Re: modperl on Win32 is still happening
Firstly: mod_perl is a good choice. :) There are other languages out there which can probably do the same job 90% of the time. But what you have chosen is a language that is: 1. OS independent 2. Highly extensible via CPAN 3. Fast to cook, good to eat It's not a question of whether you can do job X with language Y, but it's more of how easily it is done, and how flexible it can be. mod_perl tends to do pretty well in that path.

Re: Best version of Apache for Win32 deployment
Because you used theoryx5's perl/modperl/libapreq2 built for VC8, along with the AL build of 2.2.4 ALSO built for VC8, everything is dandy. Equally if you used ActiveState perl (built VC6) + a VC6 build of modperl and libapreq2 with the ASF distribution of httpd 2.2.4, everything is dandy. Is there a VC6 build of modperl + libapreq2? I've been following the links on the ASF site, so it's always been theoryx5. To date I've been using ActivePerl all the way, so it's still a combo of VC6 Perl + VC8 modperl. But so far so good... Mix and match at your own risk.
Re: Best version of Apache for Win32 deployment
I haven't looked into this, but the fact that AL's mod_perl (compiled, presumably, with VC8) doesn't work with, again presumably, ActivePerl (compiled with VC6) may be another example of the dangers of mixing components compiled with VC6 and VC8. Point taken.

Sorry man, I'm not too familiar with Catalyst, so I can't pinpoint the problem. But if your tests are good with a clean install of Apache2 + mp2, you may want to check compiler used to build Catalyst (see Randy's email on the VC used for ActivePerl, Apache, and modperl). I suppose Catalyst is not a pure-perl implementation?
Re: Apache 2.2.6 and mod_perl 2.0.3
You may want to hold back on 2.2.6. Use either 2.2.4 from ASF or 2.2.5 from ApacheLounge. Tracy E Schreiber wrote: Hi, I believe that mod_perl 2.0.3 is not compatible with Apache 2.2.6.

Best version of Apache for Win32 deployment
Hi all, Just want to share something I read today (fairly old news) at ApacheLounge: http://www.apachelounge.com/forum/viewtopic.php?t=1907 Since many (most?) people who use Apache from Apache Lounge also use mod_fcgid and/or mod_perl, it seems that 2.2.5 will remain the best Apache version to use until Apache 2.2.7 comes out. It is expected that new versions of mod_fcgid and mod_perl will be needed for Apache 2.2.7, because the proposed changes will not be backward-compatible with Apache 2.2.5 and earlier. My point is that for Win32 modperlers, you may want to check out 2.2.5, and hold out for 2.2.7 (and a potentially new release of modperl to support it).

Re: PerlRequire executed 4 times on apache startup
I've had this same experience on Win32 Apache 2 as well. It could be related to the MPM model that the Win32 implementation employs. Tobias Zeising wrote: Hi all, I have a weird problem: on startup apache executes 4 times a Perl Script I included via PerlPostConfigRequire startup.pl in the httpd.conf. The startup script contains following code: #!/usr/bin/perl my $file = 'c:\tmp\test.txt'; open(INFO ,$file) || die Error $!; print INFO test\n; close INFO; print STDERR test...\n; 1; After starting the apache server (with an empty test.txt) the error.log contains as expectet one time test... and the test.txt contains curiously four times test. That means apache has executed the startup.pl four times. I have found http://modperlbook.org/html/ch04_07.html but that apache config test would only explain the execution of two times. Actually the startup.pl contains some code for preloading a huge amount of modules, so this needs about 10 seconds instead of 2 or 3. Hope anybody knows or can explain this behaviour.

Re: Internal Server Error
Hello Perrin,
I'm interested in how you defined your handler with the 'method' attribute:
sub handler : method {
...
I've read http://perldoc.perl.org/attributes.html about attributes, but
it does not seem to suggest that tagging the method attribute to
subroutine has any programming advantages, unless you're interested to
list the subroutines with that attribute. But I suspect there's more to it.
Perhaps you can clue me in on this?

So on the first case,we need to write the handler as

because Apache may call the function directly as Package::Name::handler.
on the second case,we write handler as,
sub handler { my $class = shift; my $r = shift; ... }
because '-' is a method calling.
For method handlers, you also have to declare it differently.
In mod_perl 1:
sub handler ($$) {

Re: Using Apache 2.2 from ApacheLounge for Win32 modperl
Actually note that it isn't a release and is being rerolled. Seems Apachelounge is doing themselves and their users a disservice, again. I disagree. ApacheLounge's binary distribution is the only one that (configured with modperl) survives an application restart. As I posted in an earlier mail, ASF's binaries do not work in modperl setups. So far I have not received any response (only verifications) that contradict my findings. I applaud the people who put in effort (AND maintain a web site for that) to fix a long-standing problem, and share it with the professionals at large. It's a lot of work, and it takes a great spirit to think for the rest of us code compiler noobs.
Re: Using Apache 2.2 from ApacheLounge for Win32 modperl
This might be a result of what was mentioned before about possible problems using the binaries from http://www.apachelounge.com/download/ (which is compiled with VC++ 2005) with ActivePerl and ActivePerl-compatible ppm packages (which are compiled with VC++ 6). Mixing these can lead to conflicts, as discussed at, eg, http://search.cpan.org/src/SHAY/Win32-UTCFileTime-1.46/INSTALL You're probably right. The only saving grace is the Apache binaries seem to be nicely decoupled from the modperl/ libapreq2 code. I have not had much issues marrying them together. The only thorn I'm dealing with is that spaces in directory names is not good. But I can live with that.
Using Apache 2.2 from ApacheLounge for Win32 modperl
Hi all, While ApacheLounge makes available a Win32 binary of Apache2.2 that seems to work better for modperl than the distribution from apache.com, be advised that if you intend to use libapreq2, you may not want to use the mod_perl binary from ApacheLounge. I don't have the technical details, but if you try to use ApacheLounge's mod_perl and theoryx5's libapreq, you will not be able to use Apache2::Reload at the very least. For some reason, the MSI version of ActivePerl (tested with build 822) is more stable than the AS version in terms of starting up httpd on system startup, and service restarts. So please avoid the latter. My recommendation: 1. Use the Apache2.2.x binary from ApacheLounge 2. Use the MSI version of ActivePerl, NOT the AS version 3. Use the mod_perl library from theoryx5, NOT from ApacheLounge 4. Use the libapreq2 library from theoryx5 Tested on Windows XP SP2 x86
Using modperl from ApacheLounge
Hi all, Earlier on I was sharing the discovery of an alternative binary for Apache on Win32 at Apache Lounge (http://http://www.apachelounge.com). Here are some updates on the implementation: 1. There are binaries for Apache 2.2 and modperl2, but none for libapreq2. The ppd from theoryx5 works though. 2. Still have to be careful with spaces in directories. Seems to work, though OS will pop up a httpd failure message. Can be scary to the client. 3. Apache2::Reload seems to be responsible for crashing the httpd service at OS startup. But if you take omit it from httpd.conf during the first Apache service start, stop the service, add it (Apache2::Reload) back in, Apache will start and restart without problems. In other words, you can use it during development, but not during deployment.
Frustration over Apache 2.0/ 2.2 restart failure = possible package found
Hello Henrik, all, With kind references from the modperl community, I've managed to confirm a working Win32 modperl stack that will survive an apache restart based on zero application code config. Not only does this stack do exactly that, it is based on a more recent Visual C++ compiler, and claims improved performance over the reference binary from Apache. Please check out the binaries from: http://www.apachelounge.com/download/ To summarise the procedures: 1. Install Apache 2.2 binaries from ApacheLounge 2. Install ActivePerl (I tested on build 822) 3. Install modperl via ppd from ApacheLounge 4. Install libapreq2 from http://theoryx5.uwinnipeg.ca/ppms/ 5. Insert the following into httpd.conf ServerSignature on LoadModule perl_module modules/mod_perl.so LoadFile C:/Apache2/bin/libapreq2.dll LoadModule apreq_module modules/mod_apreq2.so My test OS is Windows 2003.

Re: SV: [mp2+Win32] Frustration over Apache 2.0/ 2.2 restart failure
William, the point I was trying to make is: 1. My restart test scope merely loads modperl + libapreq. There is ZERO application code loaded. In other words, all I did after installing modperl + libapreq is to ONLY load them into httpd.conf: LoadFile c:/Perl/bin/perl58.dll LoadModule perl_module modules/mod_perl.so LoadFile bin/libapreq2.dll LoadModule apreq_module modules/mod_apreq2.so Noticed there is no other code loaded. No database used. Super duper minimal test model. 2. When you said that you managed to get modperl to survive an apache restart on a Win32 OS, I'm really keen to understand how you have done it differently. Is it because you are not using libapreq? Or is the default installation settings not optimal? Foo, you missed my point all together. Something in YOUR PERL APP is opening resources that are locked and will prevent another process from obtaining them for approx 60 seconds. What, why and how are your puzzles, I'm afraid. There's nothing in the generic apache/perl/modperl that did this to you. More debugging logs, finer debugging details might help you pin it down.

Re: [mp2+Win32] Frustration over Apache 2.0/ 2.2 restart failure
Hi all, A little more tests reveal the following: If Apache was not installed in the default location (c:\program files\apache foundation\apache2.2) and instead installed into a path that does not have spaces (eg. c:\Apache2.2), while restarting will still fail, you can manually start the service again much faster; almost immediately after it stops. It is possible to write a monitoring windows service to start the apache service if it detects that it has stopped, but it's not quite the elegent solution that people want to hear about. So while it's better, it's still not good enough. Apache must still be able to perform a restart on its own. Any suggestions?

Hello Henrik, Yes we have conversed earlier and shared the pain on this same point. My FreeBSD installations were relatively painless in comparison to the Win32 counterparts. The sad truth is that my clients are more comfortable with Windows OS, and I have to support our products on this platform. It's either I get modperl to work, or we have a product overhaul to move over to .NET (which I hope will not happen). It's quite strange that nobody else has this problem. It's definately a critical operational concern. I am starting to suspect that Perl/ modperl is quietly exclusive to the non-Windows world. I hope someone in this community can prove me wrong...

What's strange is, when this error would pop up, it would flood 5-10
errors like this in a row, all within the span of a few seconds. Then
things would return to normal and I wouldn't get any errors for awhile.
On my site, I'm getting hits every couple of seconds, if not more
frequently. In my startup.pl, I have something like this to
initialize the MySQL connection:
Apache::DBI-connect_on_init(DBI:mysql:mydb: 127.0.0.1

(NOTE: for the hostname, I was using localhost for awhile, and decided
to use a direct ip in case localhost is actually being resolved, to
get rid of one more layer of translation)
My code around line 1059 in MySQLBroker.pm looks like this:
sub _mysql_exec {
my ($self, $dbcall) = @_;
my @resultsArray;

my $sth = $self-{_dbh}-prepare($dbcall);

}
$sth-finish;
return [EMAIL PROTECTED];
}
Also, on a fairly inconsistent basis, I'm also getting not a CODE
reference errors.
To me, it just seems like mod_perl is very unreliable and
unpredictable. The same code that worked reliably (albeit slow) in
the CGI world is now extremely unpredictable in the mod_perl world.
FYI, I'm aware of the persistent state issues in a mod_perl world and
have gone to great lengths to debug any persistent state issues that
might be affecting things.
At this point in time, I'm extremely tempted to rewrite everything in
PHP. I really want to avoid that, but mod_perl is causing me too many
headaches to justify it, as I've already wasted a week of effort
trying to migrate my site from CGI to mod_perl.

ModPerl on Apache 2.2 not suitable for Windows platform
Hi all, This is a summarised follow-up on my earlier post detailing my concerns with modperl on Apache2.2 (with the latest installations of ActivePerl + modperl) not being to restart gracefully. In other words, during a restart it crashed and stopped. I have received similar observations from Randy Kobes. If there is someone who figured a way to resolve, hope to hear from you. In the meantime, modperl on Apache 2.2 (in Win32 environment) seems to be more stable so far. Hope this helps.

Re: Performance Questions
Let us know how it goes - using XSLT that way is often desirable from a developer's point of view, but is usually impractical due to the processing overhead. If you end up successfully using this technique in production without complaints from users please let the list know, I'm sure a few other people are curious too! Just a personal opinion: wouldn't xslt juice out the cpu faster than a conventional template engine (eg. HTML::Template)? If you are running a fairly high-use environment, you may want to implement stuff that is easy on the processor. Thinking aloud though, perhaps if the xslt engine caches the compiled xslt file, performance may improve...
