Re: [RFC] mod_perl Digest path...
Hello, MSMailing a link is easy, converting to a format that looks almost exactly MSlike the current version Geoff sends out is a bit harder (yes, I can MSspawn lynx, which gets most of the way there, but its all coding that MShas to be done). I think the point is emphatically NOT that it has to look *exactly* the same as it does not, but that it should definitely be sent to the list as it is now, as readable text rather than a link. I mean, this IS a *mailing list digest* we're talking about, isn't it? Since I skip some messages with less interesting subject lines, I love getting the mod_perl digest in my INBOX to fill me in on things I may have missed and I'm sure many people feel the same way. FWIW, I'd be glad to write the HTML-text script and send it out to the list, myself, if the digest switches to e-mail-the-link; I could even write a procmail recipe so it happens automatically. MSI mean, we're all web developers right? If you don't have a browser MSrunning the majority of your day then something is seriously up (or MSyou're out of work :-). And we want the digest more widely viewed than MSjust this list - not everyone interested in mod_perl development MSsubscribes here, and take23 is the right forum to host the digest MS(IMHO). It's just a matter of, sometimes you check your e-mail over a slow link or whatever, and it's nice to just be able to skim it right then and there instead of inserting it into your mental queue to check it later. I agree strongly that digests should be mirrored on take23. Have we thought about just taking the current digest e-mail and putting it there? I'm sure as mod_perl developers nobody would find the lack of pretty HTML horribly disconcerting. MSIf someone wants to do the work it takes to make Geoff's life easy for MSgenerating the digest in both HTML and plain text then please volunteer MS(and please don't volunteer unless you really mean it - we get lots of MSvolunteers for take23 work that barely ever turn out to be people who MScan afford the time). If it means that we'll lose the e-mailed digest, I'll put in whatever effort is necessary for this. MSBut it has to be as easy as uploading one version, and the take23 CMS MSautomatically sending out an email to the list. Anything else isn't MSworth it. I think you're being unfair here; it's impossible for it to be exactly as easy given that the task has gone from (send plaintext to list) to (upload XML to take23, convert to HTML, convert to text, send to list). You just mean it isn't worth it to *you*, the maintainer of take23. :) Humbly, Andrew -- Andrew Ho http://www.tellme.com/ [EMAIL PROTECTED] Engineer [EMAIL PROTECTED] Voice 650-930-9062 Tellme Networks, Inc. 1-800-555-TELLFax 650-930-9101 --
Re: Development Environment
Hello, STI was wondering if anyone has successfully setup a development STenvironment to allow for multiple development copies of modules used STwithin Mason components. Also, to have the appropriate changes to the STmodules shown within the development environment. This can also be a general mod_perl question, because it's also not easily solved for handlers and shared Perl modules (there are a couple hacks, like translating the source code to munge package names, but they're usually not pretty). GEDIs there some reason you don't want to run several independent GEDinstances of Apache? What if there are 20 mod_perl developers at your company? You either need to do admin work to partition the developers by what modules they write, or run 20 Apache instances, which may be very expensive.

I believe Apache::ASP::Lite should be named CGI::ASP::Lite because it creates ASP objects for use in perl CGI scripting. Further, unlike most Apache::* modules, it does not run under mod_perl which is what the Apache::* namespace is for. It is built for the CGI model of execution, which Apache does in fact do, but the Apache::* namespace is misleading in this regard. Further, there may be a namespace collision one day as Apache::ASP currently relies on a variety of sub Apache::ASP::* modules to do its dirty work, such as: grep ^package src/ASP.pm package Apache::ASP; package Apache::ASP::STDERR; package Apache::ASP::GlobalASA; package Apache::ASP::Request; package Apache::ASP::Response; package Apache::ASP::Server; package Apache::ASP::Application; package Apache::ASP::Session; package Apache::ASP::State; package Apache::ASP::CGI; package Apache::ASP::Collection; package Apache::ASP::CollectionItem; package Apache::ASP::Load; What if you wanted to create your own objects as you extend the framework, or I create a Apache::ASP::Lite for use in Apache::ASP ( very possible ). Again, I beg you to pick another namespace for your work. Note that it will likely be used by others if more appropriately named in the CGI::* namespace.

You either need to do admin work to partition the developers by what modules they write, or run 20 Apache instances, which may be very expensive. Yes, it's a lot of work to set up an environment for many developers to work in. I work on servers which do this sort of thing now. As we're all working on the same project, we have a single httpd.conf for all Apache instances on the develpopment server(s) plus for example ghhttpd.conf for my own personal settings where they differ from those which the others are using at the time. In httpd.conf there's a section something like this: IfDefine ghhttpd ServerRoot /home/ged/whateverServerRoot DocumentRoot /home/ged/whateverDocumentRoot Port 4321 User ged Group nogroup ErrorLog /home/ged/log/error_log CustomLog /home/ged/log/access_log combined PidFile /tmp/ghttpd.pid LockFile /tmp/ghttpd.lock Include conf/ghcustom.conf /IfDefine and my httpd instance is started something like this: /path/to/httpd -Dghhttpd -f so that the appropriate personalization is used.

Re: Passing data among handlers
Drew Taylor ([EMAIL PROTECTED]) said something to this effect on 01/30/2001: I have a slightly different twist on this question. We run Registry scripts on our site for debugging purposes. I would love to have a module for saving variables/data structures on a per-request basis (like the current Apache notes), but internally using pnotes under mod_perl, and some other mechanism (package vars like I'm using now?) under everything else. The purpose of this being so that I could have a nice interface for per-request data that I could pass between different (non-OO) modules. This sounds vaguely familiar to what you did Barry. Can you elaborate a little? Hey, wait, now we're talking about Apache::Session. In the perldoc for Apache::Session, see in particular the section titled "Sharing data between Apache processes"; it's almost exactly what you're asking for, except the storage location is arbitrary (and can be transparently moved around).

Re: Repost: Anyone using virtual server for mod_perl hosts?
Robert Landrum writes: The S390 appearently runs some type of software that allows you to set limits on your partitions, so no matter what, you always have some percentage of the CPU at your disposal. It's called VM and it's a lot more flexible than that. This is not the case with the Sun 1. With that machine, you must explicity set which processors you want partitioned to your virtual box. With a 16 processor Sun 1, you could set up four, four processor Sun virtual machines, all sharing the same hard drives and external adapters (NIC cards and serial ports). Exactly: with E10k (and IBM NUMAQ) you are limited to splitting things up at a "quad" (4 processor) boundary. Large systems like this are dying, I think you misspelled "beginning to be even more popular" :-) as they generally require much more knowledge than simply establishing a server farm of the same capabilities. It's much easier to higher people to set up 50 boxes (linux, NT, BSD, Solaris) than it is to find people that can configure an S390 or Sun 1. 50 boxes: no problem. 200 boxes: 5 racks or 1U, getting messy. 1000 boxes: admin nightmare. Plus you don't get much too many built-in reliability features with a 1U box. Now consider that you can run *thousands* of separate Linux images on a S/390 box which consists of just one or two frames (i.e. the size of one or two racks). It'll need hooking up to a rack or few of disks too. Far less floor space, far less power, far more reliable, far fewer cables and mess, very easy to create a new virtual machine (minutes), pretty much all maintenance and upgrading is concurrent and you can admin the whole lot from one place. Now isn't that worth having to learn a bit about how to admin a VM system? Especially since you wouldn't want some random cheap admin looking after that many boxes and customers anyway. There was a test/benchmark done where more and more Linux virtual machines were added to a system, each running Apache or INN or being a client image pulling data from the server images. The experiment was to see how many images the system could sustain. At 3 images the server images were still providing subsecond response time. The system finally started thrashing at 41400 concurrent virtual machines. I can dig out refs if people want (it was David Boyes who did it, if I recall). In practical terms, you can put thousands of virtual machines on one system: there are big advantages to sharing one large machine. The most recent big name to go Linux/390 is Telia, the Swedish Telco.

Re: RE: MSQL server has gone away ( Apache::AuthDBI.pm )
I ran into a similar problem while using MySQL and Apache::AuthDBI. I had a remote MySQL server that my apache web server connected to and used for authentication. Every so often (no pattern to this) the connection to MySQL would drop but MySQL would still be functioning properly. The only way I was able to detect whether the connection to MySQL was viable was to write my own script that would attempt to reconnect to MySQL and attempt to execute an actual query. Pinging from MySQL = Apache wouldn't work. BTW, the symptom that would present itself when the connection dropped was that apache would max out and NO URL requests would be processed.

Re: [OT] Design Patterns in mod_perl apps?
Wow!! Gunther you've done it again. I ask for some nuggets and you've given me the gold mine :) Gunther Birznieks wrote: If you look at the latter half of the on-line book at http://www.extropia.com/ExtropiaObjects/ and read the module chapters after and including the "Architecture" chapter you will see a sidebar in each chapter devoted to identifying design patterns that were used in that set of related modules. I just quickly browsed through Chapter 10 (104 pages !!) and it shines light on EXACTLY the sort of things I was thinking about. It is like the 'Design Patterns' 'Conway book' fused into one. I also downloaded the webware apps so I can disect and learn from them. I'll be busy for the next few months:) eg we use CoR in filters that are specific to handling content in our apps. We use (depending on how you view it) CoR or flyweight for dealing with stuff like data handlers (which are essentially filters for *incoming* content) 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. 3. Are there any new patterns useful for mod_perl apps? Lots. But I think you mean Web apps not mod_perl apps. Web Apps abound with idioms and design patterns. There are many which have been identified since the GoF book such as Session which I think nearly all large web apps use. :) You were correct in paraphrasing my question to mean web apps. At the moment I happened to be thinking in terms of mod_perl handlers. 4. Am I wasting my time with OO and design patterns if the goal was writing a mod_perl app? I guess it depends on what you mean by a mod_perl app. If you mean a web app that runs on top of mod_perl, then you should use good OO because I suspect you'll want to expand that app and do things later with it which means the cost of maintenance is an issue not just the speed. If, however, you are writing some custom auth handler or something like that, then the efficacy of sticking to OO is less because (A) Yes, you could lose some performance in some cases, and (B) Because the auth handler is likely to be so tiny that OO would not make sense. OO is better for larger programs so that they can be broken down more easily. I can see the distinction now. seems obvious now that I hear you say it :) PS Caveat: Don't go overboard on design patterns. GoF book was written with typical apps in mind. Web apps were not in their view scope at the time. Web apps do operate differently to regular apps and the design patterns or idioms you might wish to use may be different. Since as the GoF book puts it, all patterns have their advantages and also their consequences. Those consequences may be OK for a regular app but not for a web app. There have been tons of articles and books on Design Patterns since GoF Any specific web design patterns book you would recommend? book was out.

Re: Runaways
Actually, I've had some bad experiences with the Carp module. I was
using Carp for all my errors and warnings within mod_perl on our
development server, but when I moved it to our production server
(both similarly configured) it cause every request to core dump. I
never figured out what the problem was, but removing the use Carp;
and the calls to carp and croak stopped the core dumps.
Has anyone else had problems with the Carp module and mod_perl?

mod_perl and DBI Weirdness
Hi All, I have built Apache 1.3.14 with mod_perl 1.24_01 and PHP 4.0.4, and Ingres is installed on the system. Everything works except for one truly odd thing... Before I proceed here's my configuration information as it relates to mod_perl: Directory "/app/www/cgi-bin" AllowOverride None Order allow,deny Allow from all Options ExecCGI PerlHandler Apache::Registry /Directory (There are no PerlRequire statments in the httpd.conf file.) Now for the weirdness... Somebody has written a Perl script that talks to the Ingres database via DBI. Using the above configuration information the script does what its supposed to, and everything is right with the world. But if I add in: SetHandler perl-script to the middle of the Directory directive above, the script blows up. error_log says: DBI-connect(::) failed: E_LQ0001 Failed to connect to DBMS session . E_LC0001 GCA protocol service (GCA_INITIATE) failure.

This means you're always having to look at the man page. You may think XML::Simple results in simpler data structures; however, the mental energy expended to refigure stuff out makes XML::Simple more complex in the long term. Aside from being slow, this is another complaint about it. In contrast, the data structure you get back from XML::Tree is always the same.

Apache/mod_perl mysteriously closing connection
Hello, So we've had an extremely odd situation happeningly lately and I thought I'd query this list to see if anybody has experienced anything similar. I have Apache 1.3.14, mod_perl 1.24_01 statically compiled into it, and Perl 5.6.0 running on Solaris x86. A variety of mod_perl scripts (at the moment, all Apache::Registry style) and CGIs runs on this box. Both CGIs and Apache::Registry scripts use DBI with Oracle (all recent versions). Sporaically (perhaps 1 in 100 requests) and unpredictatably, requests seem to be getting dropped without being logged. In a browser, this would be indicated by a "document contains no data" error. Absolutely no headers or content are sent. The strange thing is that Apache also does not log any sort of access or error. Doing a packet sniff, I see that the request is delivered to Apache, then Apache gives back a TCP FIN and ACK, closing the connection without sending anything at all. On the most telling case, Apache::StatINC gave out the typical "subroutine redefined" errors, then browser indicated "document contains no data" and nothing was logged in Apache. Others seeing this have reported the bug to occur in batches, e.g. if it's good, it's good for thousands of requests at a time, then if it fails, it fails several times in a row. I'm totally mystified and it's really hard to reproduce. Has anybody else seen any behavior similar to this?

Re: Development Environment
I agree. I've seen many people try to do shared memory/cached programming in one server and it just doesn't work very well in practice. It only takes one programmer a typo to take everyone else down until the bug is fixed. From Jakarta/Tomcat to IIS to Apache/mod_perl. Developers having their own workstation is the best for testing and active development. Of course, a staging server needs to be shared. But it's a lot cleaner once the developer has debugged their own code.

Re: Translation handler continuous loop problem
"Sinclair, Alan (CORP, GEAccess)" wrote: I am hoping someone might have a clue on how to resolve this awkward problem. I have just installed a mod_perl URI translation handler to extract a session id from the URI. In general the translation works correctly by removing the session id from the URL when detected. However, a Netscape browser client triggers Apache to enter a continuous loop if I do not specify the domain name in the hostname component of the URL. The problem does not occur in Internet Explorer (that surprised me.) All these examples are from Nestcape on both NT and Unix. For example, say I enter http://lions.access.com/sp9/outage.html The translation handler works correctly. If I then enter: http://lions/sp9/outage.html There is a continuous loop in Apache and on each iteration, an entry is written to access_log. I have to stop the request in Netscape. The bizarre thing is I can enter any other URL such as http://lions/internal/whatever and there is no problem. The mod_perl translation header goal is stripping session id info from the URL in the form http://hostname/SESSION_ID/sp9/whatever It looks for sp9 in the path. I have attempted to debug by trying to send error messages to the error log without success. Does anyone have any suggestions on how I can determine why the translation handler is entering into a continuous loop when a request is sent from Netscape? I would be appreciative of any help!! I could be completely wrong but ... I can't see a problem here - although I would need to see the code. There could be an issue with how IE and Netscape actually format the header (i.e you may enter the above, but the header that gets sent may be different) - but I could be completely wrong on this ! You may wish to look at http://sourceforge.net/projects/sessionmanager/ Which is URI transhandler / session manager that I wrote for a project that never came about. I may make another release that uses PerlSetVars to configure the module if I get a chance to test it. If this does not help, then post either the code, or a URL to the code if its long, so that some of us can have a look. Greg Env is: Solaris 2.6 Apache 1.3.14 mod_perl 1.24_01
Re: Apache/mod_perl mysteriously closing connection
Hello, GEDIt sounds a little like a crash which happens before the logging routines GEDget a chance to do any logging. Yup. But if the child dies, doesn't Apache catch the SIGCHLD and report something to the global error log? I'm not seeing any messages to this effect (and I haven't been able to programmatically reproduce the error, so it's hard to catch a glimpse of the process table before-and-after). GEDAre you getting core dumps? No such luck.
