There's a lot to understand, and I've explained it too many times to care anymore. Google it. The gist of it is this: outside octets - Encode::decode(...) - manipulate it - Encode::encode(...) - the user If you do manipulation before you decode, your app will break. If you do manipulation after you encode, your app will break. Anyway, a whole article about unicode and Catalyst is here: http://www.catalystframework.org/calendar/2006/21 Learn and enjoy.

Re: [Catalyst] How to execute controller at startup

Hi All,
Thank you very much for all your valuable comments at appreciate your quick
response.
I have one more query.
I have implemented a Plugin. How can I call a plugin method from controller
outside of the controller methods.
You shouldn't.
If you need to do that, the method shouldn't be in a plugin.
Don't hack up your Catalyst app, fix your design :)
Expanding on what mst said, keep in mind that plugins are reserved for
things that need to affect the request cycle. If you just need some
functionality, write a regular module. If it needs $c, pass in $c.
Component base classes are also possible, and are a better approach
than plugins. (See C::Plugin::FormBuilder
vs. C::Controller::FormBuilder. Both are on CPAN so you can compare
the approaches.)
Finally, phaylon's Extending Catalyst guide:
http://search.cpan.org/~jrockway/Catalyst-Manual-5.700701/lib/Catalyst/Manual/ExtendingCatalyst.pod
suppose i have a Plugin named Catalyst::Plugin::MyPlugin contains a method
called sub myFunc {}
That should be my_func, not myFunc. This is perl, not java. Please stick to
the correct naming conventions for things.
TMTOWTDI, but your way is rather unconventional. Identifiers should
be lowercase (%karma_for), constants should be uppercase
($SECRET_OF_THE_UNIVERSE), and modules should be CamelCase
(MyApp::SomeThing). Anything else will make people like mst mad
because it's really really ugly.
Hope this helps.

Jonathan Rockway

The point is that both transaction A and transaction B can't go through. Web apps aren't designed to be hit concurrently by the same user; it just doesn't make sense (or work) when you're keeping state. One state has to win; this is what the DB error is telling you. You could setup locks over [submit, update flash, display flash]: User submits form A. Form A gets the lock. User submits form B. B submission blocks waiting for the lock. A updates the flash.

But it does bring up the point of better handling of exception statements by DBIx. DBIx:: is a generic namespace for DBI extensions. DBIx::Class is abbreviated as DBIC. (This comes up a lot, I should add it to a FAQ or something.) The DBIx::Class::ResultSet::find_or_create(): call should handle this exception better because it can happen in tons of different places and its not always an application or benchmarking issue. What do you think it should do? create failed. Only your app knows what to do in that situation. Maybe you are suggesting that errors be hidden so your app silently loses data? I am not in favor of that. In high load situations you WILL see this happen. I have a feeling that your app is broken then. I often do dumbass load testing on my apps and don't have any problems with transactions failing unchecked. I really think you should read about transactional isolation and how deadlocks/conflicts are handled by your RDBMS. The Berkeley DB has really good documentation on both of these things, describing both theory and how to avoid common problems with the library itself. SQLite's docs are also good. To illustrate here is an example: Your DB has a first_name table to store user first names You get a flood of new people registering and you normalize their first names to get id's 2 Users have the first name of Tom which does not exist yet You call DBIx::Class::ResultSet::find_or_create(): Both calls detect the name does not exist Both calls insert with one getting this error Now there is no real way to handle this in your app unless you do a lot of concurrency checking or queuing of inserts. Rollback and try again. Your DBMS' docs will tell you about the best strategy for dealing with this case. I'm sure there's a good-enough generic solution... if someone knows it, I would like to hear. Anyway, you should probably continue this thread on the DBIC mailing list instead. DBIC has *nothing* to do with Catalyst.

Once your CPAN starts working again, manually install Crypt::OpenPGP and let me know how that goes.

Then the END block does run.
Is this different from what you would expect?
try:
$ perl -e 'END { print going away\n }; sleep 1 while(1);'

$ _
compared to:
$ perl -e 'END { print going away\n }'
going away

From what I've observed, a signal won't trigger END blocks even

I never got any feedback on this version, so I haven't made it stable yet. If you're a MicroMason user, please try it and tell me what problems you encounter.

[Catalyst] Template::Declare view available
Hi all,
I have more than just MicroMason views :) While I was at the YAPC::Asia
hackathon last month, I was around a bunch of Jifty people and decided
to write Catalyst::View::Template::Declare. If you're not familiar with
TD, it's a module for writing HTML templates in Perl:
template foo = sub {
html {
head { title { Hello, world. } };
body {
p { This is a paragraph. }
}
}
};
Catalyst::View::Template::Declare integrates TD with Catalyst, so if
you're interested in TD, you might want to give it a try. The module
is in my CPAN directory, and it's available via git:
$ git clone git://git.jrock.us/Catalyst-View-Template-Declare
The web interface is at:
http://git.jrock.us/?p=Catalyst-View-Template-Declare.git;a=summary
Please let me know how it works for you. IMHO, it's a bit nicer than
the Jifty version since you can have your template definitions in
multiple modules (under your View's namespace), and everything is
compiled when you start your app (so that template syntax errors
prevent your app from starting). There's also some extra syntactic
sugar floating around (::Tags gets auto-imported, for example).

Jonathan Rockway

Does anyone have an example unit test that has access to $c?
As others have mentioned, this is probably a sign of a poorly designed
API. If you decide to continue further, you'll probably want to use
Test::MockObject to setup a fake Catalyst app/context. I have a class
called Angerwhale::Test::Application (code is on CPAN) that will setup a fake
Angerwhale context:
sub context {
my $args = shift;
my $config = $args-{config};
my $c = Test::MockObject-new;
$c-set_always( 'stash', {} );
$config = { %{$config||{}},
%{LoadFile('root/resources.yml')||{}}
};
$c-set_always( 'config', $config );
# fake logging (doesn't do anything)
my $log = Test::MockObject-new;
$log-set_always( 'debug', undef );
$c-set_always( 'log', $log);
# fake cache (always generates a cache miss)
my $cache = Test::MockObject-new;
$cache-set_always( 'get', undef );
$cache-set_always( 'set', undef );
$c-set_always( 'cache', $cache );
# TODO: model / etc.
return $c;
}
As you can see, I only set up the stuff I use; in this case the stash,
a log, and $c-cache. If I use something else, the test will die and I
can investigate why.
I also have a model function that returns an instance
of a model (and could be generalized to return any Component):
sub model {
my $name = shift;
croak need name unless $name;
my $args = shift;
my $context = $args-{context} || context();
$name =~ s/\W//g;
$name = Angerwhale::Model::$name;
eval require $name;
croak error loading $name: $@ if $@;
my $model;
eval {
$model = $name-COMPONENT($context, $args-{args});
};
croak didn't get a model: $@ if $@ || !$model;
return $model;
}
There's more than one way to do this, but it works for me.
