My new restarter code avoids this issue entirely. It doesn't actually
re-execute the initial script (which runs forever), it just restarts the
web server piece (and reloads the app itself).

I wouldn't touch something like this as a plugin, period.
My method is to have what essentially amounts as a file type dispatcher
which takes incoming uploads passed in, then redirects to whatever is the
most appropriate model class.
I have a Model::Upload, as well as Model::Upload::Image and
Model::Upload::Video -- in the controller, I just do:
$c->model('Upload')->process( $upload );
Put all the important bits in the model, and let it go from there.
Depending upon how you associate stuff with the users and the DB changes.
My method is to actually allow multiple Models, so I have a User processor
that runs after the Image/Video processor -- and that is what stores the
associations in the DB.
I am also actively trying to release this set of modules, but ... still some
kinks to work out before it is releasable. However, this strategy has
worked very well for me.

I have a module that knows how to create a database and then import a database dump that's kept in svn. We use Postgresql so the module simply does a createdb and a pg_restore. The database is dropped on DESTROY after the test is run. The module sets environment variables pointing to the database it created that are then used by the test script (or really Catalyst) when the tests run. This module is used at the top of any test script that needs a database for the tests. Like Peter, I have a config file that has different sections for different "modes" of operation. Mostly used for dev, testing, qa, staging, and production configurations. I have a module that manages the configuration. That is, it's a module that you pass an application "home" directory and a "mode" and it returns a hash of the config. It's separate from Catalyst because it's used by more than just Catalyst. Now, normally the configuration for the database is defined for production, staging, etc. but for "make_test" (which is the default) the dsn is empty: make_test: database: dsn:dbi:Pg: user: password: It's possible to override the host, port, etc. if the database server is on another machine. The module that creates the test database sees this and populates the PG* environment variables, creates the database and imports the data, then the test script runs and likewise the application then uses the same PG* environment variables to access the test database. > How do I get my test script to use a different config file for > the test database? Well, mostly it's not the test script that needs the configuration data, but the application. In my case all that's needed is an environment variable that says what "mode" to run in. I have a plugin for Catalyst that loads the configuration file. It's a thin wrapper around the module that loads config data. It uses an environment variable to select the "mode", but the plugin defaults to "development", which is the more common case (when running the built in server). So, test scripts can ask for a database from a common module. That module figures out where the application home is and loads the config. It's loaded in "make_test" mode by default. Since the dsn is not set the PG* environment variables are used to tell everything what database to use. When Catalyst then goes to load the config an environment variable is set that says to use "make_test". It's probably less complex actually than my description above. ;) -- Bill Moseley. mose...@hank.org Sent from my iMutt ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/

The only way I managed to do this and keep my sanity was to use the "fat model" method and then test the model layer specifically (DBIC in my case) outside of catalyst. To help with this I started using with DBICx::TestDatabase http://search.cpan.org/~jrockway/DBICx-TestDatabase-0.02/lib/DBICx/TestDatabase.pm This worked great, until I ran into problems with code relying on features of MySQL (yes I know) I then cooked up a bit (ok a lot) of a hack that relies on MySQL allowing you to create a temporary table with the same name as an existing table, the real table gets hidden. Leaving you with an empty clone of your table that disappears when you close the connection. http://dev.mysql.com/doc/refman/5.1/en/create-table.html so now when I run my tests I clone an empty DB for the duration of the test run. You have to populate it with canned data but this gives you a very consistent way to test. Again you need to be doing your heavy lifting in your model (DBIC) for this to work well. How safe this is in the long run is anybody's guess but so far its working quite well. Just don't do it on a replicating master If your wondering why I went to all this trouble. We have several developers so running multiple tests at the same time caused all kinds of strange problems and nobody wanted to maintain a DB per developer!

Re: [Catalyst] Jason Kohles' tutorial on ExtJs editable data gridsandCatalyst
Hi, I ran into some trouble while trying to extend Jason Kohle's tutorial from a one-table database to a two-table database. The tutorial had a people table with the following columns: id, name, and affiliation. I altered the affiliation column into an affiliation_code column. And then I created another table called affiliation to hold the affiliation_code and the affiliation_description. I also specified that the affiliation_code column in the people table was a foreign key which referenced the affiliation table's primary key. I then recreated the Model in the Catalyst Application. So now the people table had a 'belongs to' relationship with the affiliation table. With this arrangement, I am able to populate the grid with data from the affiliation table, but Catalyst throws up an error when I try to populate the grid with data from the people table. The error I get is : "[error] Caught exception in AdventAjaxGrid2::View::JSON->process "encountered object 'AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=HASH(0x91b8270)', but neither allow_blessed nor convert_blessed settings are enabled at /usr/local/share/perl/5.8.8/JSON/Any.pm line 426."

I indicate which one I want with an environment variable, which defaults to 'dev' (so if I forget, I only affect development data). % MY_DOMAIN=test make test My base db class (I use RDBO but DBIC would work just as well) checks that env var and picks a profile to use based on the domain value. I maintain 3 database instances, one for each domain. I basically take a dump of my production data via cron on a regular basis, and then import a recent dump to my test and dev dbs as needed. That's a one-line system() call in my test scripts in a BEGIN block. Having the 3 database instances is also nice for schema dev work, as I can make changes in dev, test them with my code, and then deploy the changes to test domain, test code, repeat for prod (unless my tests are somehow destructive of data, in which case I have checks for that env var in my tests and only run in test/dev.)

[Catalyst] Using test database with TWAM?
I assume this is more of a general Perl testing question than a Catalyst question, but I finally sat down to write real tests for one of my apps, with the hopes that I'll do this regularly for everything. I was using the Tutorial chapter on testing, and the docs for Test::WWW::Mechanize::Catalyst, for ideas. I quickly hit a wall because I couldn't figure out how to run this with a test database. Since I need to test modification and deletion stuff, but have real data, I can't just run this against my actual app. So I figured I would dump the sql from my production app and have my test program load this into a database called "test-db" or whatever, having the same format and schema as the real db, and then just drop the test db at the end of the test. Unfortunately I don't know how to do this from a test script, and I don't know how to tell TWAM to run a particular app but with a different DBIC schema (in this case, the identical one but with a different name, pointing to the test db) instead. Or how to do the same thing, but with TWAM hitting the app with the external-server method (so I can test the Apache deployment). Would be grateful for any pointers. Thanks.

Yeah, I'd already come to that conclusion.
Any suggestions for a sane(r) approach? As it's a plugin I've used I
might be able to find some tuits to experiment with an implementation.

[Catalyst] upgraded to latest catalyst runtime 5.8 and Catalyst::Plugin::Upload::Image::Magick::Thumbnail::Fixed cant be loaded
hi guys
i thought i upgrade my server's catalyst runtime package to the latest
one.
When I tried running my app, i got this error:
Could not load class
(Catalyst::Plugin::Upload::Image::Magick::Thumbnail::Fixed) because :
You are trying to modify Catalyst::Request::Upload, which has been made
immutable, this is not supported. Try subclassing

This is what part of my lib/MyApp.pm looks like:
use Catalyst qw(
-Debug
ConfigLoader

Authorization::Roles

Session::State::Cookie
Upload::Image::Magick
Upload::Image::Magick::Thumbnail::Fixed
);
Anyway, i went to lib/MyApp.pm and removed '
Upload::Image::Magick::Thumbnail::Fixed' and ran the app. Bear in mind I
still had ' Upload::Image::Magick' there.
When I tried to run script/myApp_server.pl again, I got this error:

I think (1) is more bulletproof. I think a restart costs a lot of time
and an additional call of $^X doesn't matter here.

Re: [Catalyst] Scalable Catalyst
Alejandro Imass wrote:
Anyway, the message is that with mod_worker/mod_perl you can spawn
_thousands_ of threads, getting impressive concurrency (without
counting the mutex). We have tested Catalyst applications that handle
_thousands_ of concurrent requests using off the shelf AMD 64Bit HW
and 12Gb RAM, with a Catalyst app of about 20MB RSS.
There is a big difference between having thousands of requests in-flight
at once, and serving thousands of new requests a second.
You're saying that mod_worker can do the former well, without mentioning
the latter.
I'd very much guess that in your configuration, most of your workers
(and requests) are just pushing bytes to the user, which isn't really a
hard job.. :_)
The reason that normal mod_perl fails at this is you have one process
per request, and so having many many requests in flight at once hurts.
However, if you have thousands of requests all trying to generate pages
at once, you're going to fail and die - full stop...
perl -e'system("perl -e\"while (1) {}\" \&") for (1..1000)'
will convince you of this if you aren't already :)
You can trivially get round this by having a _small_ number of mod_perl
processes behind a proxy, so that your (expensive/large) mod_perl
process generates a page, then throws it at network speed (1Gb/s or
higher if you're on localhost) to the proxy, which then streams it to
the user much much slower. This frees up your mod_perl processes as
quickly as possible to be getting on with useful work.
I'd also note that having more threads/processes generating pages than
you have CPU cores is fairly inefficient, as the more processes you
have, the greater the penalty you're going to incur due to increased
context switching overhead. (
Quite often you block on the database in most apps, which means that 1
process per CPU core doesn't hold totally true for best throughput, so
YMMV..
For the record, one of my apps can trivially do 200 requests a second,
with 3000+ concurrent requests in-flight, using a single 4Gb dual core
x64 box with one disk, running both the application _and_ the mysql server..
It flattens the 100Mb pipe to the internet I have in the office waaay
before the system actually starts to struggle from a load perspective..
That's nginx / fastcgi with 3 fcgi worker processes (no of cores +1) -
when benchmarking I found this most efficient for that application.
This is one of the things that your mileage varies significantly,
depending on what your application is doing, and anyone else's answer is
going to be lies - you _need_ to test and optimise it yourself for your
app and your workload. :)

RE: [Catalyst] website member urls
It could be also helpful if we could find a way to create urls like
http://user.hostname.com/
dynamicly as Google blogger site does.
We do this with a wildcard A record in the DNS and an Apache URL
rewriting rule that moves the hostname into the path. When I started writing
my app (in Catalytic pre-history) there wasn't any support (that I could
see) in Catalyst for using the hostname in the rules that decide when an
action is invoked and what parameters to pass to it. Things have moved on a
lot since then though so perhaps the URL rewriter could be replaced with a
better action description now.
Merlyn
If others don't know more about a newer and better way as you
suggested, can you give some hints about the way you told about?
It's pretty simple. The wildcard A record in the DNS just makes sure that
all requests for http://.ourdomain.com/ are sent to the server.
The Apache URL rewriter goes in the Apache config file and is basically a
piece of code, typically like a perl s/// regexp, that hacks the URL up a
bit so that, for example, http://anything.ourdomain.com/path might be
presented to the back end as http://ourdomain.com/ouraction/anything/path or
whatever suits you. See
http://httpd.apache.org/docs/2.0/misc/rewriteguide.html for more info on
Apache URL rewriting.
The idea I had about Catalyst supporting this more directly was just that
there might be something like the PathPart() thing that would so something
similar with the hostname so you could say something like:
sub handler : Chained('/') HostPart(something) CaptureArgs(1) {}
but from what J.Shirley said in another message it sounds like there is no
such thing. I'm afraid that's all a bit beyond me though - all my Catalyst
apps were started before the introduction of PathPart() and getting up to
date is still on my job list...
