RE: [Catalyst] CMS
That would be good. I went through this exercise a while ago and ended up using CMS Made Simple (a PHP app) because it was easy for end users to understand and there were a lot of plugins you could auto-install. Plus I only had 2 weeks to develop a system. I found Bricolage too complex and powerful to use for a simple CMS system. CMSMS wouldn't be a bad place to start from, doing a straight rewrite. I think a lot of the difficulty is in the design issues for stylesheets, templates, cross-browser Javascript and how they fit together with code plugins. Regards, Peter Dragonstaff Limited http://www.dragonstaff.com http://www.dragonstaff.com/ Business IT Consultancy _ For while I've been thinking it would be nice to have a Cat-based CMS with multiple features built on top of a platform. The platform can include basic things like Authn, Authz, Sessions, a basic user schema and pre-built HTML. The pre-built HTML can include controllers/templates/etc for registration, login/logout, openid, etc. Then on top of the platform you can have plug-and-play features like forums, blogs, photo galleries, surveys etc. If it was built the right way, you could have your choice of forums, etc. You can also only load the features that you want.

RE: [Catalyst] C::P::Authentication IE Problem - Time Issue
I was experiencing a weird annoyance with C::P::Authentication today. I saw reports of similar symptoms in the list, but nobody with my particular solution. In Firefox everything was working fine, but in all the IE browsers auth cookies weren't being stored. Eventually I grabbed a HTTP Session inspector to see how the cookies were being set. The expire time on the cookies was sent as GMT several hours in the past. What I've done before is send the server time as part of the login screen and use some Javascript to warn if the server time is more than a set time away from the client PC time. Sometimes it's server time drift, sometimes client PC time drift. It's annoying that IE simply drops a historic cookie without warning and then you think the user is typing the password wrong. As a side note, is there a way to control the session length of the authentication cookie? In your conf set: cookie_expires http://search.cpan.org/author/NUFFIN/Catalyst-Plugin-Session-State-Cookie-0. 07/lib/Catalyst/Plugin/Session/State/Cookie.pm You can set session expiry with conf: expires http://search.cpan.org/~nuffin/Catalyst-Plugin-Session-0.18/lib/Catalyst/Plu gin/Session.pm You also need to extend an expiring cookie by calling session_expires() somewhere (e.g. in auto :Private in your main controller) to resend it otherwise by default it times out after 2 hours.

Some useful pointers here http://dev.mysql.com/doc/refman/5.0/en/communication-errors.html http://dev.mysql.com/doc/refman/5.0/en/gone-away.html We put in code to wrap the DBI calls, detect the error and re-run the transactions in that case.

The OP may find a requirement to incorporate a transaction model (explicit start txn/commit/rollback) to solve this problem in MySQL; which is what they'd have to do for Oracle or Postgres or Rdb. I'd hope that MySQL reports a transaction failure when the database connection evaporates. This would allow a retry on the failed transaction. However, it may be that the Catalyst Controller / View design/implementation is only what would ordinarily be flat file accesses that use SQL instead of keyed-access flat files.

RE: [Catalyst] Re: memory usage of mod_perl process
Jeffrey Ng wrote: so are you saying in general catalyst is pretty heavy, and its not for site with many concurrent users?... No, not at all. It all depends on what your application does, how many web screens, how many peak concurrent users and equivalent requests/second, how many discrete users, how many data feeds in/out, data volumes, network transfer volumes. Your limiting factor might be CPU, database I/O or network bandwidth. Different architectural models are best for different cases. There is a cost equation between using a powerful framework that increases robustness, maintainability and speed of development versus how many servers you need. Say a server costs you $100 per month to rent and each Catalyst server maxes at 30 requests per second but you get a peak load of 90 reqs/sec. You would need to load balance your app across 3 servers. There would be an initial configuration cost and then you'd be paying $200 p.m. = $2400 p.a. more for the two extra servers. Let's say a developer, including overhead, costs you $1000 per day. If you move away from Catalyst to a lighter framework and it costs you more than 2.5 developer days extra then you're losing money. Catalyst has a lot of tried and tested pluggable modules and if you end up re-writing any of those you're almost certainly spending money. what other light weight approach would you go for? First thing, set up proper caching (either Squid or a lightweight Apache) and use a tool like Fiddler to examine the HTTP request Cache headers to make sure it's working properly. That's a huge saving. Then do profiling and benchmarking to determine exactly what the bottlenecks are before making any changes. If you're doing a lot of dynamic Ajax stuff with complex SQL, there might be a case for hand-tuning that part of the app. Look at whether you can pre-calculate and cache expensive queries or change the app design to allow this. If necessary, you could write a separate lightweight app to serve those requests. I didn't find a suitable lightweight mod_perl framework so wrote one using CGI::Session, DBIx::Class, Template toolkit. It's not that difficult. If you would like some details please feel free to email off-list or call me. However, that was an atypical case and as soon as you start needing internationalization, RSS feeds etc. I think you're better off with Catalyst. You said you need to serve JS from the same server as the heavyweight app. Assuming the JS pages are static or can be precalculated and stored in a static dir, and you have the JS below /js and your app below /app in the URI namespace: On the same server run two Apaches (or one Apache + one Fastcgi) 1) Lightweight proxy. Build it yourself from source, turn off all unnecessary options and shared libraries except mod_proxy/mod_rewrite. Use rewrite rules to proxy /app/. on to heavy server, e.g. based on an Apache 1 setup I have that's live: RewriteEngine On RewriteRule^/app/(.*$) http://localhost:2000/app/$1 [P] ProxyPassReverse / http://localhost:2000/ RewriteRule^proxy:.* - [F] The /js and /images get served by the proxy server (which has a 1MB memory footprint per child) 2) Heavy mod_perl server listening at localhost:2000. Maps /app on to your handler (40-100MB memory per child). Say you had to handle the Ajax part separately. With this model you can add another proxy entry that routes, say, /ajax/ on to another Apache server on the same host (e.g. localhost:2001) or on another host altogether (e.g. http://ajax1.zorpia.com http://ajax1.zorpia.com/ ). If you need to scale more, use DNS round robin to a set of front end proxies like this and route requests to a farm of backend servers using a shared database server. I'd be surprised if you couldn't get decent performance out of a well-designed Catalyst app. There are businesses listed on the Catalyst pages that offer consultancy help if you need further pointers. As a business I used Shadowcat Systems last year and received good technical design advice.

[Catalyst] Re: memory usage of mod_perl process
Are you hitting the database very hard? Complex joins? Are your pages very complex? No, it's a fairly simple backend processor that mostly handles XML transactions for a Flash frontend. There are some XHTML admin pages generated with Template::Toolkit (and so are slower) but they are rarely hit. For the database a typical run hits a session table, user table, writes a log table and reads data from a couple of other tables. No complex joins. The app handles user registration, some league tables, polls, competition entries and users submitting images that are approved and shown on the site. In this case I knew there was the potential for a huge number of users so went for a lightweight approach that could easily be tuned further. For a more complex app with fewer peak users I'd have used Catalyst.

[Catalyst] Re: memory usage of mod_perl process
There are a lot of good tuning tips in the Apache docs, as Perrin says. I presume you've tried things like using a lightweight front end proxy (to serve images/static files) and building a custom backend mod_perl Apache that includes *only* the modules you need. If you use the stock Fedora/Redhat Apache that's not optimal. In your Apache config preload everything pre-fork (if you use that model) including setting up the DB connection. Write code that caches expensive calculated values/lookup files/SQL values in memory with a cheap last-modified check before re-doing work. Don't set MaxRequestsPerChild too high (I use 100) as the mem usage will climb as Perl switches some shared memory variables to new memory, as the Apache mod_perl docs describe. For comparison, I'm using DBIx::Class across 15 tables and a really simple hand-rolled MVC (not Cat) for a medium volume site. It gives 'top' lines like: PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 21495 apache15 0 203m 43m 6188 S 0.0 4.5 0:01.46 httpd This can handle over 300 requests/sec with 1GB memory on an x86_64 single processor.

There are several approaches to consider: 1) Use a remote server to host part of the application and talk to it from a front end via SOAP and XML-RPC. That's a lot easier than it sounds provided your users have net access http://search.cpan.org/~rjray/RPC-XML-0.59/. 2) Write part of your app in VB or C# and supply a DLL wrapped in copy-protection. It will still be possible to crack but a lot more difficult than trying to hide perl. Bear in mind if your software is popular enough it only takes one person to crack it and list it on astalavista http://www.google.co.uk/search?hl=enq=software+wrapper+copy+protectionbtnG =Google+Searchmeta= 3) Go the Open Source route.

[Catalyst] Catalyst vs Rails vs Django Cook off
For businesses the cost-to-develop and cost-to-maintain are usually more important than handler performance. The reason is that in most medium-large transactional web systems the bottleneck is the database and not the framework. A 10-100x slowdown in using an ORM or your framework of choice doesn't make much difference in terms of end user perceived speed (assuming you serve static content from a lightweight proxy web server). It does save a lot of money in cost-to-maintain. Sure there is a place for optimised libraries and so on, but it's only worth optimising bottlenecks and the handler usually isn't one. I recently had to hand-write a TCP/IP server in Perl using POE to handle one particularly heavy case but most situations are easily dealt with by Apache mod_perl or FastCGI, in fact running Perl in CGI mode is often adequate. More important questions to me about frameworks are how: - easy to learn - quick to develop - flexible - comprehensive in terms of supporting infrastructure (templates, components) - easy/expensive to recruit staff - easy to integrate with other systems Realistic approaches include .NET J2EE Catalyst, Jifty RoR They all have strengths/weaknesses. For example, you'll get a Jifty or RoR app up quickly if you do it the standard way. If you want to build a bigger system that doesn't quite fit their model you're probably better off with Catalyst or another framework. I did one large system with Catalyst last year and it was great for that. I did a smaller system just before Christmas and wrote my own simple MVC framework for convenience. It's a question of choosing the right tool for the job.

Otherwise we would never get anything done. ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
Re: [Catalyst] problem deploying with apache: templates not found
Have you tried doing warn posedb-path_to( 'root' ) ? /home/marcl/catalyst/posedb/root Still 'Coldn't render template file error - search.tt2: not found' though, while it resides in /home/marcl/catalyst/posedb/root/src/search.tt2 Shouldn't that be /home/marcl/catalyst/posedb/root/search.tt2 Also the dump before referred to a different path with myapp not posedb dirs = [, home, marcl, catalyst, myapp, root], Regards, Peter ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
Re: [Catalyst] Force server to send data to browser....
Is there a way to send stuff as it's running, like forcing the server to send info every so often? Good question, not sure how you'd do it with Catalyst. I've done this before to show output from a lengthy batch program, using CGI.pm, sending the header then the start of the output followed by a flushed space char every minute to stop the browser timing out. Like a tail -f on a log file.

Re: [Catalyst] how to get started?
Hi burninbruce, setting up CPAN to follow prequisites and install them automatically might make it easier. # perl -MCPAN -e shell If it's the first time, it will ask a load of setup questions, choose to follow prerequisites. Otherwise you can set it on with cpan o conf prerequisites_policy follow cpan q Then try reinstalling Regards, Peter -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: 21 August 2006 10:04 To: catalyst@lists.rawmode.org Subject: [Catalyst] how to get started? I'm a programmer with many years experience with perl and some with CGI scripts but little with CPAN and none with web app frameworks. I've been trying for days to install Catalyst and haven't gotten far. I've tried both perl -MCPAN 'install Task::Catalyst' and cat-install and they both fail with many errors in various prerequisite modules. I've tried this on Sun Solaris, NetBSD, and Cygwin, and they fail in similar ways on all three. ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
Re: [Catalyst] pass array to template?
Hi Sarah
How can I pass an array to Template Toolkit, then loop through it?
You need to pass a pointer to array otherwise you get the scalar (length) of
the array:
$c-stash-{numarray} = [EMAIL PROTECTED];
