Re: [Catalyst] flash - Duplicate entries
Quoting Ian Docherty [EMAIL PROTECTED]: Did I not see something on here, or on DBIx-class list some time ago to the effect that in find_or_create there is a short window where having found that a record does not exist it then creates it. I presume that two threads could each detect that a record does not exist and then one of them would create this error. Hmm .. That would explain the other issue I'm facing: An update_or_create command that once in a while fails with a duplicate entry error. The two threads you're mentioning would have to come from the same user at the same time though to cause this problem assuming that no two users have identical session keys ... Reversing the order (try a create first, catch the error, then do a find if the create fails) was ISTR the proposed answer. But this may not help you if the problem is in the Session/Store/DBIC/Delegate plugin. Right :( Is this a problem that only affects the MySQL backend because the other storage types (memcached, mmap, etc) do not check the uniqueness of the session key?

[Catalyst] flash - Duplicate entries

Re: [Catalyst] TT and UNICODE: Garbled special characters
Quoting Stefan Kühn [EMAIL PROTECTED]:
I have a problem when outputting special characters with
Template-Toolkit and C::P::Unicode. I passed a simple template
parameter from the controller to the view. The parameter contains a
special character and is being garbled in the output.
* In controller test.pm added the following (note the German Umlaut)
sub index : Private {
my ( $self, $c ) = @_;
$c-stash-{myname} = 'düc'; # -- **NOTE** the German Umlaut
$c-stash-{template} = 'test.tt2';
}
If you use special characters as string literals you have to use utf8 at the
top of your controller.
Other than that you should tell TT that your templates are UTF-8 encoded by
passing it a configuration option in your View class:
__PACKAGE__-config( {
...
ENCODING= 'utf-8',
...
} );

[Catalyst] Catalyst + RHTMLO
Is anybody here using Catalyst + RHTMLO, especially Rose::HTML::Form, to handle forms? If yes, I'd like to know what your glue code (init forms from db, re-fill from $c-req-params etc.) looks like because RHTMLO has a somewhat different approach to handling things and I have the feeling that I'm doing things overly complicated. Other than that, I really like the way RHTMLO works and would love to see something like a Catalyst::Controller::RHTMLO module which works similar to the other form controllers out there. The existing C::C::Rose module is tied to RDBO and thus of no use for me because I very much prefer DBIC.

[Catalyst] Storing $c leaks memory?
While hunting down some memory leaks in my application I found that it's
generally a bad idea to store $c in a class as this never gets cleared up
completely, is that correct?
I'm also doing things like this which seem to cause major leaks:
$foo-bar( coderef = sub { return $c-forward( '/someaction' ) } );
While I can imagine that a closure like that can cause trouble I don't see why
the following is leaking memory, too:
in a Controller:
my $foo = Foo-new( $c );
in Foo.pm:
sub new {
my( $class, $c ) = @_;
my $self = {};
$self-{ '_c' } = $c;
bless $self, $class;
}
Maybe somebody can shed some light on this?! Is it possible (and sensible) to
weaken $c before storing it?
Thanks a lot!

[Catalyst] Catalyst Unicode woes ...
Following up on a conversion I started on the DateTime mailing-list I'd like to ask if it is really neccessary to use C::P::Unicode if a site uses utf8-encoding? I have the problem that up until now everything worked absolutely fine without C::P::Unicode, Template::Stash::ForceUTF8, Template::Provider::Encoding or any other unicode plugin because I believed that if everything is utf8 you don't really have to worry about it that much. Now I recently incorporated DateTime::Locale to get a list of localized month names. Spitting them out in my templates revealed a questionmark symbol instead of all german umlauts. I took a look at DateTime::Locale and everything seems to be correct (use utf8 at the top, etc) so this can't be the culprit. encode(utf8)-ing the month names makes them look correct. I asked about this on the DateTime mailing list and everybody suggested a truckload of plugins to incorporate in Catalyst which _ALL_ break everything else on my site except the month names which are displayed fine then. It looks like everything gets encoded twice when utilizing these plugins. So I must admit I'm stuck with this. What is the best-practice for dealing with Catalyst and utf8? Do I really need C::P::Unicode to make this work correctly? What about the various TT plugins? And why the heck is everything double utf8 encoded when using these plugins that everybody else seems to use? Thanks a lot for any input! --Tobias ___ 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] Catalyst Unicode woes ...
Tobias, I tried jrock's advice of adding C::P::Unicode to the Cat app you sent me a couple days ago - and it does fix the encoding problem. I also did that but it only works in some cases. Try adding a block element to the FormFu YAML file (or a comment for the date element) that contains some Umlauts and they will get double-encoded even with Unicode loaded. Most of my site now works with the Unicode plugin loaded but still some pages with FormFu forms are double-encoded - not all of them though. --Tobias ___ 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] Catalyst Unicode woes ...
Zitat von Tatsuhiko Miyagawa [EMAIL PROTECTED]: Similarly even if your templates are encoded in utf-8, Template-Toolkit doesn't know which encoding they are in, until you set BOM to your templates or use Template::Provider::Encoding to explicitly specify the encoding to decode the template. So you're saying that there's no sane way using TT without Template::Provider::Encoding (or something similar)? I admit I haven't really grasped this whole Unicode issue fully yet (and I don't seem to be the only one as it's causing trouble for lots of people) but this really should be more DWIM out of the box if possible ... Especially since utf8 is becoming the de-facto standard for encoding everything should just work. Yeah, I know, I'm naive :) Concatinating utf-8 flagged variables with utf-8 encoded byte string causes automatic SV upgrade, which causes double utf-8 encoded string. Hmmm. So my templates are utf8 _ENCODED_ and the strings coming in from other perl modules are just utf8 _FLAGGED_. When TT concats them together during process() the result is wrecked because of the automatic upgrade. Correct? You might want to look at the manpages of encoding::warnings and perlunitut. Just quickly tried out encoding::warnings which outputs nothing at all but I'll give it a closer look. I have a couple of hacks to workaround that, like Template::Stash::ForceUTF8 that you mentioned, and Encode::DoubleEncodedUTF8 is probably the most evil one, that fixes the double-encoded utf-8 strings back to what you mean. Too evil to use on production but would be still useful to catch bugs like that in testing. Hacks are not an option here :) And there must be a right way to do it. --Tobias ___ 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] Catalyst Unicode woes ...
View::TT ENCODING: UTF-8 Template provider will see you are running a modern Perl (UNICODE flag in provider) and then look for a Byte Order Mark. If not found it will then decode your content based on the ENCODING setting. No, you don't need Template::Provider::Encoding if you only have one encoding in your templates. Yes you need Unicode (or the older Unicode::Encoding) plugin so that input params are decoded and output is encoded back to utf8. Yes, it all starts to make sense :) Thanks for all the great clarifications. MyApp is working fine now with C::P::Unicode and the ENCODING setting. By the way, does anybody know why the ENCODING option is undocumented? IMHO, it really should be mentioned in the Catalyst::Manual alongside some best-practice for Unicode.

[Catalyst] TT macro to avoid excessive $c-uri_for calls
I'm wondering if it has any bad side effects to have a TT macro which is set to
$c-uri_for. If I'm remembering previous posts on this topic correctly, calling
uri_for() repeatedly has quite a big impact on performance which really matters
most for my current application. I have this in a global macros.tt2 file:
[%
base = Catalyst.req.base;
static = Catalyst.config.hosts.static;
images = Catalyst.config.hosts.images;
site.url = {
base= base
static = static
images = images
}
-%]
That way I can easily change the location of my static files and images to
another server or place using the Catalyst config file and generate links like
this:
img src=[% site.url.images %]logo.png /
a href=[% site.url.base %]user/whateverbla/a
etc.
Any comments? Thanks!

To specify where Catalyst should put the temporary files, set the 'uploadtmp'
option in the Catalyst config. If unset, Catalyst will use the system temp dir.
__PACKAGE__-config( uploadtmp = '/path/to/tmpdir' );

Unfortunately this doesn't work for me (all file uploads are placed in the

Now, there's this in Catalyst::Engine:
#321: $c-request-{_body}-{tmpdir} = $c-config-{uploadtmp}
But HTTP::Body::MultiPart doesn't consider $self-{tmpdir} in its call to
File::Temp. Looks like tmpdir isn't used at all and really should be added
as an object method to avoid poking in the HTTP::Body object.
Have I misunderstood the purpose of uploadtmp? If not, I'd be happy to
provide patches for HTTP::Body::MultiPart and Catalyst::Engine.

Now, there's this in Catalyst::Engine:
#321: $c-request-{_body}-{tmpdir} = $c-config-{uploadtmp}
But HTTP::Body::MultiPart doesn't consider $self-{tmpdir} in its
call to
File::Temp. Looks like tmpdir isn't used at all and really should
be added
as an object method to avoid poking in the HTTP::Body object.
Have I misunderstood the purpose of uploadtmp? If not, I'd be happy to
provide patches for HTTP::Body::MultiPart and Catalyst::Engine.
This sounds like a bug in HTTP::Body, a patch would be great, thanks!

[Catalyst] C::P::StackTrace and HTML::FormFu
Following up on my post from yesterday to the HTML::FormFu mailing list I found out that using the Catalyst::Plugin::StackTrace plugin together with HTML::FormFu (and Catalyst::Controller::HTML::FormFu) results in an enormous slowdown when using lots of options for e.g. select elements. See one of my earlier posts here: http://lists.scsys.co.uk/pipermail/html-formfu/2007-May/11.html The culprit is the option respect_overload = 1 given to Devel::StackTrace on line 63 of C::P::StackTrace (0.06). After removing it performance of HTML::FormFu is fully restored. The option was not present in earlier versions of C::P::StackTrace (0.02), that's why it all ran well on only 1 out of 3 of my machines, which incidentally had the old version installed. Now, I'm not really sure what's the best way to fix this, so I thought maybe some of you may have an advice. For now, I just disabled the StackTrace plugin.

Re: [Catalyst] Re: Shoot out -- Catalyst / RoR / Other MVC apps --
But, this does raise another question I have. There is plethora of modules that are to help Perl be more OO like and stricter which is cool, but are there any good de-facto standard modules that are used by the majority of people wishing to be more OO compliant. That'd be Moose, I suppose - A complete modern object system for Perl 5: http://search.cpan.org/dist/Moose/ Haven't really looked into it yet but I always wanted to know if there are any plans on incorporating this into the Perl 5 core and/or any patches in bleadperl that boost Moose's performance (which, I suppose, is not up to par with plain Perl objects) like the Class::C3::XS patches we saw recently? --Tobias ___ 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] Shoot out -- Catalyst / RoR / Other MVC apps --
Hmmm, no, I don't think that is what I was talking about (though it might be) I thought the competition was made up of teams that were part of communities rather than companies. Oh, okay, nevermind then. Sounds interesting, though. Tell us if you find something out about it. Plus, I'm sure RoR had a representation in the comp I was thinking of. This comp is just PHP/Perl/Java. Ruby and Python didn't make it because there were too few teams. The interesting thing is that Perl was first left out of the competition and got included later on due to the Perl community's protest :) --Tobias ___ 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/

[Catalyst] Template::Provider::DBI and Catalyst
Following up on a recent post to the list concerning templates in the database I'm wondering what the current status of Template::Provider::DBI is and if anyone is using it in production within Catalyst? I just found out that it seems to be incompatible with Catalyst::View::TT::ForceUTF8, for example (ForceUTF8 seems to ignore LOAD_TEMPLATES. Haven't looked at its source code yet to tell what's going on). Looking at the source of Template::Provider::DBI I see that the database handle is stored within the object which AFAIK is created once during server start by my View class initialization. I was told that storing database handles in objects for subsequent queries should be avoided by any means. Of course it could just be me who got burnt doing this under mod_perl :) There's also an error message on every request: prepare_cached(SELECT date_modified FROM templates WHERE filename = ?) statement handle DBI::st=HASH(0x91eac08) still Active I assume this is because there is no $sth-finish() statement: http://search.cpan.org/~timb/DBI-1.53/DBI.pm#prepare_cached Thanks for any clarification! --Tobias ___ 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] C::C::FormBuilder question
I was just looking at this last week, as I was using the code as a basis for a new controller. I suspect that it's never been tested, because as far as I can tell, it incorrectly reads the config from the controller object, rather than the application object. Yeah, I stumbled across this the other day but was unsure if it was done on purpose (for a controller-specific configuration rather than a global config).

Assuming you are using DBIC, try:

[Catalyst] DateTime Timezone
My application stores all dates in a MySQL database in the UTC timezone. Because I'm doing further calculations with these dates after retrieving them via DBIx::Class I don't want them to get auto-inflated into the timezone of the current user. The DateTime POD recommends doing date calculations only with dates of the same timezone and having everything in UTC should make things work like they're supposed to work (I hope). I think the DateTime objects should only be converted for displaying purposes (i.e. when they're going to be displayed in a TT template). Is that correct? If so, what's the best way (and where's the best place) to achieve this conversion?

Re: [Catalyst] Last Chance / Last Day: Web developmentplatformcontestand Perl / Catalyst
Having only one team for Perl is quite bad, especially since one of the organizers happens to be the iX magazine (http://www.heise.de/ix/), which has a big influence in the german speaking world. :/ Today I was in a meeting with one of Germany's top twenty internet agencies to speak about the future of our (home-brewed Perl-based) community app. I spoke to the person in charge of technology who of course tried to persuade me that Java and .Net/C# is the way to go. Even worse, he was convinced that Perl has no object- orientation features at all! He was surprised when I told him about the CPAN and Perl's flexible object capabilities. Unfortunately this is not an isolated case. One of Germany's most successful web portals serving several hundred million page impressions per month with Perl recently started hiring Java developers. I hate to say this, but Perl is really lacking some sort of marketing. To my mind Catalyst could be the new killer-app that has the potential to resurrect our favorite language. But not if we can't get the word out. This is really frustrating. Catalyst's website is one big mess. Go to the wiki section and you get gazillions of links on one page. Click on documentation and you receive ugly POD pages. This is just not up to standards set by other frameworks. Don't get me wrong: The content and documentation is better than most other frameworks but the presentation just sucks. I recently met another fellow perl dude and we're currently brainstorming what has to change to make Perl and the Catalyst project more appealing to the average CTO, technical lead, dude-who-is-in-charge- but-thinks-perl-is-dead :) Sorry, had to get this off of my mind ... -- Tobias P.S.

Re: [Catalyst] Catalyst Bricolage Integration
We do something similar with the Krang CMS publishing content served by CGI::Application. We have it write out templates and metadata for each application (story in Krang terminology) in separate directories [...] To do this kind of thing with Catalyst, you might want to just publish little data files (XML or whatever) with your templates and set up your web server to pass those to Catalyst. To get the same sort of setup This sounds like a cool idea. However, I must admit that I don't fully understand it. Can you give an example of what your metadata files contain? I suppose your stub scripts contain perl code which are eval'd by the CGI::Application backend? I don't see a possibility to get Bricolage to publish a template AND some sort of metadata file at once. Is Krang capable of doing this (publish little data files WITH the templates that are then read by the backend application) or am I misunderstanding things here? I now have a setup which allows me to publish stories from Bricolage into my Catalyst template space. This is not sufficient because Catalyst is not able to tell which story (i.e. id of story) it is dealing with to display dynamic stuff like user feedbacks to an article for example. That's where your metadata files come in, I suppose?

[Catalyst] Special characters and MySQL issue
I have my content-type header set to ISO-8859-1 because I'm dealing with
legacy data from a latin1 encoded MySQL database (otherwise data from the
database is not displayed correctly in the browser). There's a form on my
site for searching users by attribute. Now here's the problem:
Doing a search where, for instance, firstname = Müriam (note the
German umlaut) the search result contains users with a firstname of
Myriam (note the y instead of the german umlaut). I tried to trace down
the problem but was unable to really figure out what is going wrong. The
data from the form is URL-escaped correctly to M%FCriam. I tried putting
the following in the controller handling the request:
$c-log-warn( $c-request-param( 'value' ) );
and it spits out:
[warn] M
(note that everything after the german umlaut is missing - maybe just a
console problem?)
I access the model like this:
my $rs = $model-search_like( {
$c-request-param( 'attribute' ) = $c-request-param( 'value' )
} );
The mysql query log shows the search string as:
SELECT [...] WHERE [...] LIKE 'M\xfcriam'
Entering a query with this search string manually into the mysql console
client yields no results - as expected because there is no user with a
firstname of Müriam.
Any ideas on what's going on here? :)
Thanks in advance for any help!
