Re: Suggestions on an XML-RPC Service using modperl?
As far as the cacheing goes, we have had extremely good luck with IPC::ShareLite used to share info across mod_perl processes. --Jon R. Chip Turner wrote: Bruce W. Hoylman [EMAIL PROTECTED] writes: Ciao! I would like some input on an intranet web service I am currently in the process of designing, the core of which will be modperl on UN*X. Excellent choice. This works quite well. Of course, like others on this list, I might be a bit biased. The service itself is to access a couple of back end data stores given parameters received in an XML-RPC request, then return the results in an XML-RPC formated response. The data from the back end sources will be loaded into memory at service initialization, for fast access. The data is small enough and memory plentiful enough to allow this. How often does the data change? How is it stored on the back end? You may not need to cache anything if, say, you have a decent SQL database on the backend. Caching never hurts, but it isn't always necessary. The Cache::* modules may be of use for this, though, should you still need it. You also might want to consider not sharing the data in each process; the complexity gained vs the memory lost by storing it in each process may be a workable tradeoff. I probably would try it first with no cache, then a per-process on-demand cache, then finally a shared cache, in that order. That's pretty much it in terms of the high level data flow. It has to be relatively fast, OTO 5+ requests/sec. as a relative volumetric. This should be quite easy. I don't have the necessary setup handy to benchmark it, but I imagine you can easily achieve performance at that level using Frontier::RPC inside a mod_perl handler. We typically use custom code for interfacing the handler, but IIRC the Frontier module comes with a mod_perl handler that, if not enturely suitable, is easily modified to your needs. I'm going to use modperl due to the embedded perl interpreter characteristics it provides, allowing initialization overhead to be incurred at startup. I also wish to use an in-memory, read-only hash structure shared across all modperl processes for access to the cached back end data, rather than making expensive calls to these stores for each request. Again, throughput is critical. Five hits/second should be absolutely no problem. If you expect slow clients, a mod_proxy in front of things (http://perl.apache.org/guide) can help. I would like your thoughts on the cache management concept of the service. I'm looking at MLDBM::Sync as the mechanism for managing the filesystem representation of the in-memory hash content. What to manage the in-memory structure itself in terms of accessing its content? Is a Tie structure too expensive? I want to end up with a single structure accessible to all of the modperl processes, loaded at service Chip -- Chip Turner [EMAIL PROTECTED] Red Hat Network
Re: Apache::Session getting DESTROYed in wrong order
Hi Ken, refcount destruction. I've declared %session as a locally-scoped variable, so it should evaporate before global destruction, unless it's got circular data structures or something. Anyone know what might be going on? Do you have a simple case we can test yet? Aaron
ANNOUNCE: Apache::Gallery 0.3
Hello! Version 0.3 of Apache::Gallery has just hit the wires. Apache::Gallery creates a thumbnail index of each directory and allows viewing pictures in different resolutions. Pictures are resized on the fly and cached. Changes include: - Made Inline dir configurable. (Tim Coleman) - Made it configurable which information about the image should be viewed. (Thomas Eibner) - Added GallerySizes option. You can now choose which resolutions the user can scale between. The Gallery will not allow scaling to 641x480 if you only configured 640x480. (To prevent evil people filling up your disk) (Me) - Handle spaces in files and directories correct. - Now possible to rotate pictures on the fly. (Thomas Eibner) - Copyright picture can be included on each picture (Thomas Eibner) - Comments for each picture changed to be in picture.jpg.comments (Thomas Eibner) - Scale thumbnails correct when images are rotated 90-degrees. (Me) and other bugfixes. The code can be downloaded from http://legart.dk/code.html or your local CPAN mirror and a demo can be seen at http://pictures.legart.dk/ Michael
Win32 modperl-2 binary
Hi, An Apache-2/modperl-2 Win32 binary package is available at ftp://theoryx5.uwinnipeg.ca/pub/other/Apache2.tar.gz for those Win32 users who want a preview of things to come. This archive will unpack into an Apache2 directory, underneath which is a blib subdirectory containing the necessary perl files. These are included when starting Apache by a modperl directive found near the end of conf/httpd.conf, where a sample Hello World modperl handler is also found. Some editing of httpd.conf will be necessary if this package is installed in a location other than D:\Apache2. Within the blib/ subdirectory is some documentation on modperl-2.0. The package was compiled with the cvs sources of Jan 1, 2002, using VC++ 6 and an ActivePerl based on perl-5.6.1. The libmodperl.so library in the Apache modules/ directory will most probably not work with other Apache-2 binary packages. Being under development, there are bugs present; in particular, when stopping an Apache-2 service a memory error results if modperl is enabled. Please let me know of any problems you might have in getting this package installed; for questions/problems on Apache-2, see the docs at http://httpd.apache.org/docs-2.0/, and for modperl-2, see the information at http://perl.apache.org/ on subscribing to the dev mailing list. best regards, randy kobes
[RFC] Apache::MIMEMapper
hi all... hope everyone had a nice holiday. as you catch up on your email, I thought I would throw (yet another) RFC out there for anyone who is interested. Apache::MIMEMapper maps PerlHandlers to file extensions. It extends the default AddHandler directive so that you can have a configuration like AddHandler Apache::RegistryFilter .pl AddHandler Apache::SSI .html .pl here, .pl files chain their output together using Apache::Filter with Apache::RegistryFilter and Apache::SSI. This idea is touched upon in the guide http://perl.apache.org/guide/snippets.html#Setting_PerlHandler_Based_on_MIM and has its origins in a thread between Jim and Doug http://marc.theaimsgroup.com/?l=apache-modperlm=94895394029331w=2 though Apache::MIMEMapper takes a different implementation approach. Once I implemented this I started to have lots of fun with it - I hope you will too. the module can be downloaded from http://www.modperlcookbook.org/code.html or http://www.modperlcookbook.org/download/Apache-MIMEMapper-0.10.tar.gz and the README is attached. --Geoff NAME Apache::MIMEMapper - associate file extensions with PerlHandlers SYNOPSIS PerlModule Apache::MIMEMapper PerlTypeHandler Apache::MIMEMapper AddHandler Apache::RegistryFilter .pl AddHandler Apache::SSI .html .pl Alias /perl-bin/ /usr/local/apache/perl-bin/ Location /perl-bin/ SetHandler perl-script PerlHandler Apache::Registry Options +ExecCGI PerlSendHeader On /Location DESCRIPTION Apache::MIMEMapper extends the core AddHandler directive to allow you to dispatch different PerlHandlers based on the file extension of the requested resource. This means that you can now have .pl scripts under htdocs/ (or wherever) without resorting to a Files based configuration. Apache::MIMEMapper also adds the ability to stack PerlHandlers transparently using Apache::Filter. Handlers are added to the PerlHandler stack in the order they appear in the httpd.conf file - PerlSetVar Filter On is set if more than one extension is associated with a specific Perl module. EXAMPLE PerlModule Apache::MIMEMapper PerlTypeHandler Apache::MIMEMapper AddHandler Apache::RegistryFilter .pl AddHandler Apache::SSI .html .pl Alias /perl-bin/ /usr/local/apache/perl-bin/ Location /perl-bin/ SetHandler perl-script PerlHandler Apache::Registry Options +ExecCGI PerlSendHeader On /Location In this example, .html files are scheduled for processing with Apache::SSI. Additionally, .pl files outside of /perl-bin are handled by Apache::RegistryFilter and Apache::SSI (in that order). Because the SetHandler directive supercedes all other mod_mime directives, all files inside of /perl-bin are processed using Apache::Registry. NOTES The current logic checks AddHandler for something that looks like a Perl module, so AddHandler server-parsed .shtml still works. The criterion for deciding if Apache::MIMEMapper intercepts the request is whether the handler is in the form Foo::Bar - it checks for '::'. This is not ideal, but simple and sufficient for most cases. FEATURES/BUGS Apache::MIMEMapper is a PerlTypeHandler. It does just about everything that mod_mime does (via MIME::Types). The only place where it interferes is for content-negotiated requests, where the AddLanguage and associated directives are necessary. Should you need these directives, you can install Apache::MIMEMapper as a PerlFixupHandler instead.

push_handlers, set_handlers
Apache 1.3.22 mod_perl 1.26 I have noticed some strange behavior when attempting to stack handlers below the 'ChildInit' phase. This code executes fine when placed in a server initialization script: Apache-push_handlers( PerlChildInitHandler= \My::Child::handler ); When using the code below in a server initialization script without any apache config directives the handler does not get called. Apache-push_handlers( PerlHandler= \My::handler ); When applying the following apache conf directive the handler seems to only get called occasionally (initialization of child process?). Files *.html SetHandler perl-script /Files Although, when using the 'push_handlers' method at another part of the request phase the handler gets called occasionally. Apache-push_handlers( PerlFixupHandler= \My::Other::handler ); When using the method below the handlers do not get called at all. Apache-httpd_conf(EOF); Files *.html PerlHandler My::handler SetHandler perl-script /Files EOF Apache-httpd_conf(EOF); PerlFixupHandler My::Other::handler EOF Of course when setting the directives into the apache conf all seems to work well. PerlFixupHandler My::Other Files *.html PerlHandler My SetHandler perl-script /Files Any ideas as to why this strange behavior? When trying to use the 'set_handlers' method it blows up stating the request object is not created. I cannot see the reason why the request object should be needed to set/push handlers which are used to 'handle' the request phases. Thanks,

Have a strange problem using modPerl as follows: OS: Windows 2000 Professional Webserver: Apache/1.3.22 (Win32) mod_perl: mod_perl/1.26_01-dev mod_perl is loaded in the httpd.conf file (LoadModule perl_module modules/mod_perl.so AddModule mod_perl.c), and also appears in the .htaccess file for the TWiki directory: Files * SetHandler perl-script PerlHandler Apache::Registry Options ExecCGI PerlSendHeader On /Files The Application i'm using is called TWiki (http://Twiki.org), and if you view some page within Twiki, close the browser, open a new one and hit the link that takes you to the front page of Twiki, the last page you looked at in the just-deleted browser will be shown instead of the front page. TWiki does not exhibit this behavior when run as a CGI program, and also I just checked and it has the same behavior using Mozilla 0.9.6. FWIW, I tried updating mod_perl using cpan and it claims i'm up to date. Any suggestions on how to fix this? TIA, Dave LeBlanc

I'm not familiar with this sw, but I'll assume that it remembers the state (the last visited page). Does Twiki claim to be mod_perl clean? It's probably not coded with persistency in mind or happens to have the closure problem under Registry. As a temp workaround use Apache::PerlRun instead of Apache::Registry.
