Re: Do all apache childs create persistant mysql connections?
1) We have no idea why this happens at that particular time. There are no crons that run then, and we think have a finite ammount of users accessing the system who do not do anything different at the time the spike happens. The site is public though, so perhaps spiders could be doing this? Any suggestions? Try study your access log and see if you find something there. 2) Does Apache create a new mysql connection/process for EVERY child apache process that is spawned? I assume some apache processes are spawned to handle simple non-database actions such as retrieving a graphic or static html file. Because we're using Apache::DBI, does this mean that even these little processes are creating a big mysql process? yes, if you are using Apache::DBI, that's what happen, one presistence connection for each children. Since connection to mysql is fairly 'cheap', it might be a good idea to disable Apache::DBI and establish a connection everytime you need them. Or alternatively, try reducing your max apache children setting, that should ease your overloading problem with mysql. Good luck. Tor.
Re: How would you organize custom logging?
Instead of developing something new, how about extending the combined/common log format? That what I'm doing in my place, where we have to store a few extra bits of info so to make the log more useful for debugging, I added a little routine in my startup.pl, to setup a few additional env variable, which I linked the routine to mod_perl via the PostRequestHandler. By adjusting the combinded format to store these env vars, I build the log format that address my need. Tor. Marcin Kasperski wrote: I am to provide some custom logging in my mod_perl application. Omitting some unnecessary details, I need to store some information after processing each request, putting this info into some central log (be it file or database) common for all apache processes and (if possible) common for multiple machines. I would like to ask for any suggestions/hints/patterns/... but there are also some specific qustions: 1) Apache somehow gathers notes from multiple processes into single access.log and error.log. Is it possible to reuse this functionality somehow for writing my custom information somewhere else? Considering such functionality is already present I would not like to reimplement logic protecting from simultaneous write from multiple processess... 2) Looking at the name, seems it is LogHandler where custom logging should take place. But does it really give real advantage over just logging on the end of PerlHandler? If so, how should I pass data between handlers - just stick to some perl global variable or use pnotes? 3) Are there any tools of 'gather logs from multiple machines to the central location' you would recommend? -- ( Marcin Kasperski | Communication takes place between people, documents ) ( http://www.mk.w.pl |are secondary.

Re: Issuing rollback() for database handle being DESTROY'd
I recently noticed some strange error messages in my error_log. This is
from animelyrics.com, which uses Apache::ASP and MySQL.
Issuing rollback() for database handle being DESTROY'd without explicit
disconnect() at (eval 9) line 22.
The above line keeps repeating over and over in the error log. There are
two things that confuse me...
(1) I never use rollback() anywhere in my code... so I'm wondering if
something else could cause a rollback.
I get the same problem if I don't explicitly disconnect from the database.
You can ignore this problem if you're just making SELECT queries. Also if
the MySQL version you're using doesn't use transactions then it
autocommits data by default. DBI is also autocommit by default. If
you're annoyed by the error. put a 'dbh-disconnect' at the end of your
scripts.
(2) The "(eval 9) line 22" message doesn't tell me what file the error is
in. The modperl guide suggested adding the following lines to my perl
startup file so that the messages would show the correct file:
use Carp ();
local $SIG{__WARN__} = \Carp::cluck;
...but they don't seem to have any effect after I added them and did an
"apachectl restart".

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.

Elephant resources, referred to by Ken Williams. http://www.reno.quik.com/snow/elephant.html http://www.lazoo.org/elephants/elephant_facts.html http://www.lazoo.org/elephants/ELEPHANT.GIF 3. Pros and cons 3.1. Should the name change? 3.1.1. Perhaps, just maybe, it should be Doug's decision whether mod_perl needs a name change? (Jason Bodnar) 3.1.2. Personally, I think the name mod_perl should be kept, and mod_perl hackers should start referring to themselves as "The Mod Squad". A logo could be created based on the shape of Linc's hair from the Mod Squad TV series. (David Emery) 3.1.3. Keep the name! Why in the world should we throw away an established brand name? mod_perl is recognizable, it tells something about what it is about, and isn't too "flashy". If we need to say something about the abilities, then let's do that with a logo and perhaps some catchphrase... (Salve Nilsen) 3.2. Bridge or independent product? --- 3.2.1. This talk is about a commercial success. The /perl.apache.org/logos/mod_perl.gif logo represents a bridge between two products (makes one think of a gadget!), not really a product. I remember my first interest to Java associated with the coffee cup, or my first interest to Perl associated with the camel, or even Apache's feather. (Victor Zamouline) 3.2.2. In the case of an "independent product", I think that Mod_Perl should have its own isolated symbol. What if some webmasters will also want to include their tribute to Perl and Apache on their pages? Then, the three logos aligned together make a perfect family. (Victor Zamouline) 3.2.3. But that is what it is. A very cool bridge indeed, but a bridge. (Ask Bjoern Hansen) 3.3. Symbols 3.3.1. I was thinking about hedgehog as one that protected from everything, exactly like mod_perl... (Stas Bekman) 3.3.2. I suggest we keep the camel. Maybe give him lots of muscle with the apache feather in there somewhere. (Baiju Thakkar) 3.3.3. What about the red brick base of a building, with mod_perl inscribed on a brass plaque? Suggestions of sturdiness, of foundation, and "for-all-seasons" come to mind. Since the logo might show the intersection of building and ground, one version could have tufts of grass, the other snow. It could adapted, much in the way the Linux penguin is adapted and co-opted banners and such. (John Burns) 3.3.4. The Eagle idea sounds really strong and symbolic behind ModPerl, and the graphical image of it would be highly customizable, portable, simple and color-independent. (Victor Zamouline) 3.3.5. "The association between the image of a white-tailed eagle and the topic of Apache modules is a trademark of O'Reilly Associates." (Jim Winstead) 3.3.6. How about an oyster? Perhaps not as american-patriotic but just think how sexy it sounds. (Randy Harmon) 3.3.7. The O'Reilly Eagle is a Tawny Eagle. Thar be golden, spotted, bald, imperial, harpy ... well, plenty to go around. (Michael Dearma
Re: Logo / brand
Eagle on top of camel and the Apache feather somewhere in a middle... probably too complicated for a small scaled logo... I am afraid, yes. We have not yet reached any opinion on whether the logo should represent a "bridge" or an "independent product". In the case of an "independent product", I think that Mod_Perl should have its own isolated symbol. What if some webmasters will also want to include their tribute to Perl and Apache on their pages? Then, the three logos aligned together make a perfect family. Vic.

Although for servlets, I would say top 50th at least if you don't want a completely crappy OO servlet architecture. I have organized a series of personnel trainings in a number of huge French companies, and I have been constantly trying to spread the mod_perl word and look at people's reaction. If I talk about mod_perl on Monday: A young computer genius (you know the kind of guy who will build his own company when he is 25) will return to the training on Tuesday with the Eagle book in his hands. A well-placed VB script programmer just won't care. He will get very nervous when I pronounce "Unix". A convinced Java programmer will desperately seek for equivalent functions for Enterprise Java Beans, CORBA, RMI, etc, then he will just shrug his shoulders. A decision maker will sleep until I say "performance". He will completely wake up when I bring up statistics from Stas' guide. Then he will ask me if I am willing to come back next week to give a profound training on mod_perl, and then he will never call me back. As I understand the companies' philosophy, mod-perl's advantages that we bring up here are actually DRAWBACKS for them, as compared to VB Script. They used to find immediate solutions for an immediate contract. When I ask a question to a Perl or Java developer, most of the time he can explain me the whole theory behind it. On the contrary, a VB developer always answers "I don't know, I have always done this way and it works". So, a company hiring VB developers knows that these are humble and obedient guys who will make the application work, even if an extra semicolon will ruin the whole program. And that is perfectly OK with such companies because they sell the product and the MAINTENANCE behind it (they call it "maintenance", but it actually means re-writing the whole program when the client only needs an extra semicolon). But a good Perl programmer is more often uncontrollable, he writes a perfect program, but no one else understands it, and if he quits the company tomorrow they won't find anyone else to do the "maintenance". So when I spread the mod_perl word, I make sure I don't make my client hire another bunch of VB programmers after what I told them about mod_perl during the training. :))) I also tried to take individual VB/PowerBuilder/etc. guys and teach Perl to them. Well, I can make them understand the technical side but not the BEAUTY of Perl. Maybe I am not a perfect trainer, but after such trainings I see these guys LITERALLY TRANSLATE their programs from VB to Perl. Just to make a resume, I am afraid Mod_Perl will remain an elite-oriented product. That is not really embarassing, because the education guidelines change too, and more and more guys switch to the elite layer, bringing up their own projects. So if this talk is about spreading mod_perl to the whole Internet programming community, wouldn't it be better to say, making mod_perl THE CHOICE of the BEST Internet projects? Vic.
Re: Happy Birthday mod_perl Guide
according to the mailing list archives, the Guide was first announced on 03/12/1998 so it makes a year now ! Many kudos to Stas and to all that have participated (the list is *long*), as well as many thanks. LOTS OF THANKS to Stas and to all contributors!!! I still carry the full printed version of the Guide with me wherever I go. Vic.
Re: mod_perl Programmers demand is going up...
Now the question is: if this is truth and you feel the same way, how do we make the world know that there is a great demand for mod_perl programmers and that people should learn mod_perl and not the stright-forward choice like VB, ASP or other technology that drives the web? Great sites using mod_perl may want to explicitely state being proud of it, with a kind of mod_perl logo. I will willingly decorate my mod_perl'ed site (www.jazzvalley.com) with a mod_perl stamp on every page. That takes a strong logo and... possibly a more artistic name for mod_perl? Vic.
Re: mod_perl Programmers demand is going up...
-Message d'origine- De : Robin Berjon [EMAIL PROTECTED] There are a few logos on the site, and we can add some more (I don't know if we would manage to agree on one, though it'd give a stronger sense of "brand"). Right. This talk is about a commercial success. The /perl.apache.org/logos/mod_perl.gif logo represents a bridge between two products (makes one think of a gadget!), not really a product. I remember my first interest to Java associated with the coffee cup, or my first interest to Perl associated with the camel, or even Apache's feather. The problem I see with changing the name is that there is already stuff out there that carries the name. Well, there have been precedents in history when a product found a new name the day it wanted to tell the world about its existence. Look at how many names java had gone through. Also, looks like most software products now tend to take an existing notion from life, use the word for the name and the image for the logo... sort of marketing. :))) Vic.
Re: mod_perl Programmers demand is going up...
Maybe what we need is some open enrollment courses I can organize that in France, I am in direct communication with all French computer training companies. Vic.
Re: mod_perl Programmers demand is going up...
To my opinion, out of the responses to a definition of a "mod_perl experience", two are worth emphasizing: 1. Perl programming style with mod_perl techniques in mind 2. Abstraction from standard CGI constraints and high stakes on mod_perl's features unavailable in vanilla CGI There should be a definition, right? :))) Vic.
Logo / brand
Talking about "let's do something" topics on the mod_perl list is a waste of time, unfortunately... The motto of this list regarding new things is "think it, implement it and give it"... This is somewhat too straightforward, Stas. Look - I only suggested there should be another name and another logo, and we have already had the "Eagle" proposition from Ged, and the watermarks samples at http://b179a.studby.ntnu.no/mod_perl/watermark/ from Salve. The Eagle idea sounds really strong and symbolic behind ModPerl, and the graphical image of it would be highly customizable, portable, simple and color-independent. Many sites will thus accept to host the logo on the front page, and many books will reveal a mystery behind an appealing eagle image. I sat down and looked at Salve's "Powered by mod_perl" watermarks for some time, trying to imagine "Powered by Eagle"... What about "Eagle Perl"? "Powered by Eagle Perl"? Vic.
Re: Logo / brand
"The association between the image of a white-tailed eagle and the topic of Apache modules is a trademark of O'Reilly Associates." So it is either a question of getting O'Reilly's authorization, or abandonning the eagle idea. Stats proposed a hedgehog. John Burns proposed a red brick base of a building. Vic.
Re: Logo / brand
"The association between the image of a white-tailed eagle and the topic of Apache modules is a trademark of O'Reilly Associates." The association between Camel and Perl is also O'Reilly's trademark, yet we see a camel on www.perl.com, right? Vic.
Re: Perl Domination in CGI Programming
* Most CGI apps do text processing, where perl excels at Well, if the trend continues we ought to learn Java some day :) Java is magnificent, but VERY BURDENSOME when it comes to doing any kind of text processing or designing tricky structures. There are plenty of packages and tools written for Java that make it POSSIBLE to do it all, but it is still very AWKWARD to code, as the language is the same. Java is good for very technical applications, not good at all when you want to relax and program to have fun. I don't really think it will become a competitor for clever and ambitious projects. Victor.
Re: W32 + Apache::DBI ?
I have been digging around in the FAQ and archives for information about people running mod_perl on a windows box and also using Apache::DBI, but have come up with nothing. I am under the impression that it is not going to work becase whenever I try to load up the Apache::DBI module apache starts up and then exists immediately leaving this in the error log: [Mon Oct 25 15:06:11 1999] file .\main\http_main.c, line 5890, assertion "start_mutex" failed I once spent a good deal of time, trying to use Apache::DBI under WinNT. I had to give up as I did not find any solution, nor someone who would share a similar experience. The problem was: whichever way should I call Apache::DBI during Apache initialisation (whether it should be using PerlModule, or PerlRequire, or by having Apache::DBI called in any other Perl script run during Apache initialisation), I would always get the same error: Can't locate object method "trace_msg" via package "DBI" at C:\Perl\site\5.00503\lib/DBI.pm line 311. END failed--cleanup aborted. On the contrary, Apache::DBI would work perfectly if NOT in Apache context, but I would probably not need it. :))) The author of Apache::DBI recommended me to upgrade, but I WAS using all the latest versions. I definitely have an impression that there are not enough folks in the "W32 + Apache::DBI" community, so you just have to rely upon your own debugging skills. Victor.
Re: W32 + Apache::DBI ?
Anyone having this problem can also fix it by adding this line to the top of the END block (around line 311): return unless defined DBI::trace_msg; # return unless bootstrap'd ok If this works, it seems to be the easiest solution. Thank you Tim. Victor.
Re: Any help showing examples of database only web site w/mod_perl/my sql
I would like to build a 100% DB contained web site. Meaning all users home directories, files etc.. exists within a database. Any examples or places to look would be greatly appreciated. I am working on a similar project, look at http://www.jazzvalley.com. I have about 5000 musicians in my database, and each one has his own homepage, automatically generated but also containing stuff which can be personalized for each musician. Same thing for musical scenes, with a completely different implementation technique (much more personalization). I am now working on an extension to this system, which will allow each of the musicians to have a unique URI access, the URI's (non-existent, a priori) being analysed by translation handlers and automatically translated into script calls with parameters. Lincoln and Doug's book contains excellent and very complete explanations on how translation handlers work, thanks to Eric Cholet who pointed me to the right direction. Victor.
