Re: [Catalyst] Attribute::Handlers wont work in own classes under catalyst

Catalyst breaks regular subroutine attributes. Apparently, it tries to
parse them all so other code never gets the chance to parse them. I've
seen this problem before while using a module (which used subroutine
attributes) along with Catalyst and I decided to work around it
instead of looking for a proper fix.
Good luck. Hopefully someone else can come up with solution other than
using Catalyst's own attribute handling framework.

Of course (I assume you're talking about Ash Berlin's reply). Using Windows messages from Perl is clunky and would involve using XS code. And, even then, I'm not sure if it's possible at all without hacking perl itself. The message processing queue is probably either handled by perl itself or not handled at all. In both cases, I have no idea how it would be possible to interrupt the currently executing code when a message arrives without special hooks on the perl interpreter itself. If perl is ever going to fully emulate signals under Win32, using messages is probably the way to do it. But I'm not sure if it's possible to do that without modifying the interpreter. Note that, even then, it wouldn't be simple because Windows messages don't invoke a callback on arrival. They just sit on a queue waiting for the application to dequeue them and act accordingly. I think they're more like X Window Events than signals. They're used for all sorts of things such as requesting a window to be repainted, sending a key stroke or mouse event, for IPC (and for communication between threads) and probably for a lot more. -Nilson Santos F.

I don't really think using Moose would fit this specific example, but
since you seem to be developing using Perl, it might be a nice

If you're using objects instead of hashes it's pretty common to use

module). So, instead of $obj-{property}, you can use $obj-property,
which is a bit cleaner.
Perl 6 will take care of making that: obj.property
I also just remembered that there's actually a module called Acme::Dot

For example you can create url-action which edits some objects and include
it in many templates. This is not like
ordinary template toolkit's include - this component can show itself, modify
data, receive request params etc, like
any web page. And this doesnt depend on whether this action is directly
called from browser or included in some template.
You could have some thing like this:
sub nice_page : Local {
my ($self, $c) = @_;
$c-forward('object1');
$c-forward('object2');
}
Then, inside nice_page.tt:
[% INCLUDE object1.tt %]
[% INCLUDE object2.tt %]
Should do exactly what you want. And, well, if it doesn't you can
always use Catalyst::Plugin::SubRequest.

rest of the URI manually.
This is specially useful on those tables where each line links to a
different item. Then, instead of something like:
[% FOREACH item IN items %]
[% c.uri_for('/item', item.id) %]
[% END %]
Use something like:

I am not ripping on this decision, just asking if you can go into your rational for this a little bit. Nowadays, when conservative stats are showing that at at least 95% of the users have Javascript enabled (and some other stats showing numbers like 99.3% of the user have it enabled) it's hard to sustain a case against Javascript. Sure, if you're designing a government agency site or a bank site it might be needed to support all kinds of users. But even Google has decided against supporting non-Javascript enabled browsers in some application (e.g. JS disabled = no Google ads) I'm sure there are good reasons backing up this decision since losing 0.7% to 5% of the advertising revenue means losing approx. 70 to 500 million dollars.

I've been thinking a lot about these sort of things lately but I couldn't come up with a clean way to do it the way I envisioned it. I think one of the most relevant concepts of these toolkits such as GWT is the ability to have everything represented as widgets. I don't know if it's just me but I've always failed when trying to to cleanly code real widgets using the Catalyst + TT + DBIC combo. I always ended up with something that violated MVC (or was just plain ugly). Either I had lots of TT code that talked directly to the model or I had view logic leaked into my controllers. But then, maybe I'm just too picky or simply unable to think of an obvious good way to do it. Then on particular pages you can use the GWT concept of widges to create models to represent bundles of functional and have a TT template to convert that into something meaningful. I'd like to see this renderer bundled with a good Javascript library like Jquery to make it more easy to create dynamic controls. Hmmm... I've never thought of it from this angle (i.e. having the widgets as models which would then be rendered by TT). Maybe that's the obvious way of doing it I would've never thought of because I primarily associate models with data. Anyway I have a whole pile of fake-code around playing with the idea but nothing firmed up yet. Anything publishable? Maybe looking at some (pseudo) code that demonstrates how you envision it working could make your ideas clearer to everyone. But either way it is, I think it might be great addition to Catalyst.

[Catalyst] Performance Tip (regarding URI handling)
I've previously posted about my performance issues regarding TT. At
the time, one of Matt's suggestions for improving performance was to
reduce the usage of uri_for() whenever possible.
I had some list pages where I'd need to display dozens of items and
link to each one of them and all my links were built using uri_for(),
e.g. [% c.uri_for(/item/view/$item.id) %].
I decided to give Matt's advice a try and changed that to something
along these lines:
[% base_item_uri = c.uri_for('/item/view/') %]
[% FOREACH item IN items %]
[% base_item_uri _ item.id %]
[% END %]
This resulted in a ~20% speedup on these pages - which is a quite good
speedup for such a small change. So, if there's anyone else suffering
from some performance issues like myself, this might help out a little
bit.
I don't really know if the Catalyst devs can make uri_for() work
faster in a sane way (maybe some sort of caching of URI objects?) but
until then, I think I'll stick to this slightly less readable
approach.
I hope this tip can help others as it did help me.

Since MSVC licenses are expensive, I'll assume you don't have one and you'll follow the gcc path. The easiest way to get everything working using gcc is to install Bloodshed Dev-Cpp with is an open source IDE-wannabe. After that you'll just need to set up some environment vars and your CPAN shell will automatically recognize what it calls a gcc environment. There's also something called Strawberry Perl, which supposedly makes things easier. When I've tried it, I couldn't get things to work at all, so I prefer the AS Perl + Dev-Cpp combo. It's a tried and tested setup, which I've replicated to many boxes already. If you've already got all of this set up, you can ignore it and just try updating DBI and, hopefully, your problems will be gone. -Nilson Santos F.

There's a defacto standard for writing Catalyst applications. The Catalyst users have an opinion, the CGI::App might have another one, the Mason users who knows... maybe another one, and so on. So the newbie might finally start learning Python or Ruby. And those other languages probably also have choices between templating systems or ORMs. The thing that actually makes Rails so successful is the fact that it has everything already sorted out. You can't really learn Rails without using ActiveRecord for instance. If the newbie gives up on Catalyst and ends up learning another language it won't be because of having to learn TT and DBIx::Class along with Catalyst. It would probably because he's a Windows user and things don't work as smoothly as the alternatives. Most people don't really want nor need the flexibility provided by Catalyst, they'd rather have a pre-packaged framework that just works. This whole conversation boils down to what are the aims of Catalyst as an open source project. In order to gain popularity there should be less focus on flexibility and more focus on achievability. However, in most serious developments this won't help much, it'd just be a lot of work and the only benefits might be a dozen new users - there would be no real benefits for the existing users and, most importantly, for the core devs. -Nilson Santos F.

[Catalyst] Chained actions usage and DBIC performance
Lately I've been using chained actions a lot, since it ends up making
everything look cleaner and more organized.
I tend to structure things in a way that I've got some Catalyst
actions that load some items from the database which are the root of
the chain and then I've got another set of Catalyst actions that
actually do things with those loaded items (e.g. /item/12/view,
/item/12/edit, and so on).
Sometimes, those items also have subitems and those might even have
another set of subitems. In these cases, when using Catalyst and
DBIx::Class it can be useful to prefetch stuff for performance
reasons. But, using my setup it's not currently possible to do that,
so I end up issuing lots of queries to the database since the initial
root item didn't prefetch anything, because it couldn't know in
advance what would be needed by the chained actions.
Most of the item loading code I've previously mentioned looks like
this (simplified):
sub load : Chained('/item') PathPart('') CaptureArgs(1) {
my ($self, $c, $id) = @_;
$c-stash-{item} = $c-model('DB')-find($id);
}
The only work around I could think of is to prefetch everything and
hope that it would result in a performance gain, at least on average.
But, honestly, I find it a kind of crappy solution so I didn't even
implement it.
I'd like to know how people usually handle this because there must a
better way than ignoring performance concerns at all.
The only better way I could think of would be if DBIC's -find()
worked in a similar way to -search() and only actually fetched the
values when they were needed. So I could add prefetch conditions
arbitrarily using stacked find() calls. Maybe this should be suggested
on DBIC mailing list? Or am I just complicating a trivial situation
and there's a simple way around this problem?

The advantage is that the entire dataset is fetched before the page is loaded. This means that clearsilver never needs to call into perl, which is the slowest part of TT. However, the syntax is really ugly, and fetching 1000s of rows from the database when 90% of them are going to be discarded by a conditional in the template is pretty inefficient. Careful coding can avoid that. There's a reason Google and Yahoo use Clearsilver and not TT. I've never heard of ClearSilver before. I'll take a look at it.

[Catalyst] Catalyst Performance issues
Hi everyone, Recently I've been facing some performance issues in my Catalyst application and the situation worries me a little bit. The first optimization I tried was to start prefetching everything I could and it indeed improved the performance quite a bit (by a factor of 2 or so). But it still isn't enough. I've got pages that take 3-4 seconds to render with a single user using the application while the database query takes something between 0.15-0.20s to complete. Whenever the application faces a moderate amount of usage, users start complaining. So, in my quest for optimization, I tried profiling my Catalyst application. It saddened me a little bit to find out that, apparently, at least 60% of the time (probably more) is spent inside Catalyst, TT and DBIC internal routines (a big cycle eater is Class::C3). Particularly, URI handling seems to take a lot of time (maybe this was influenced by the fact that I profiled using the builtin server). I'd like to know if there are any performance tips or really just how do you get acceptable performance from your Catalyst application in moderately complex or large pages (especially regarding pages where there might be hundreds or records fetched from the database). Thanks for any help and just in case it might be useful in order to diagnose what I could've done wrong, here's the profiling output of dprofpp -R -O 50 for my application: Total Elapsed Time = 298.9974 Seconds User+System Time = 44.42747 Seconds Exclusive Times %Time ExclSec CumulS #Calls sec/call Csec/c Name 7.52 3.341 0.010 33082 0.0001 0. next::method 7.00 3.109 38.560 86056 0. 0.0004 Template::Stash::XS::get 6.32 2.809 3.041 5163 0.0005 0.0006 DBIx::Class::ResultSet::_collapse_ result 3.78 1.680 5.675 18010 0.0001 0.0003 URI::_generic::abs 3.05 1.357 1.581 63205 0. 0.

Right. But next::method calls also seem to weight in a little bit. But I really have no idea on how (and if) it could be improved. I think maybe uri_for isn't as efficient as it could be; you might find you're better off doing uri_for once to get a URI object and then just appending ids to the end. Considering that at least 23% of the time is being spent inside URI::* methods I think I'll take a look at this. URI handling being so expensive really surprised me. The killer seems to be the Template::Stash::XS::get time; assuming it's basically a table that you're generating, perhaps adding a static routine to your code that chucks out the HTML for that in an efficient perl fashion might help? I don't know if it would help that much, since it means only 7%. Its cumulative time is so high because it accounts for all the next::method lookups and DBIC methods, etc. But avoiding using the stash would only provide a maximum speedup of 7%. Oh well, maybe if I focus on improving both URI and stash usage I can make things run about 20% faster or so. Maybe it'd be nice if someone came up with a faster drop-in replacement for TT... any volunteers? ;-) -Nilson Santos F.

Manually running and timing the queries as output when DBIC_TRACE=1. Switching from running a $rs-next loop inside TT to loading the objects inside the controller (through $rs-all). Then I tried using $rs-all inside the template and noticed the time spent in the controller going down and the spent in the end action going up by approximately the same amount as I've timed when manually running the queries. There are some generic things you can do to speed up TT (use PROCESS instead of INCLUDE, use the support for constants if you have any, make sure you are using the template cache), but I'd do a profile sorted by real time before spending the effort on them. The template cache gives me a performance boost varying from almost 0% to 10% (average 3%). Using PROCESS instead of INCLUDE makes a tiny difference in my case. I'll take a look into using constants, I never knew TT had them. Does your template do anything that might cause DBIC to fetch more data? Some of them, yes. The ones in question, no - they prefetch everything they need (at least according to DBIC_TRACE there's nothing missing and only one query is issued). -Nilson Santos F.

I've never really used chained actions (except when experimenting with
it) because all the code I could come up with looked like this - which
are extremely confusing action definitions IMO.
I think chained actions would work a lot better if there was a way to
chain things in a more abstract way. So that, in this example, you
could have a single 'view' action which would handle all the cases and
the preceeding action would just populate the resultset accordingly or
something to that effect (of course, your reports may actually be
completely different, but in my own use cases it does make a lot of
sense). However, the current way is also useful in some usage cases,
so I think Catalyst should probably have two ways of chaining stuff.
Of course, there might be better was to achieve the same functionality
that I'm not aware of. For now, I need to forward things around and do
it a little backwards (e.g. /dailystatusrpt/view/2005/10/08). It's
kind of counter intuitive, but it works.

Re: [Catalyst] Minor Problem With Tutorial
On 8/14/06, Kevin Monceaux [EMAIL PROTECTED] wrote:
Anyway, I'm at the end of the BasicCRUD section of the tutorial where one
creates the Books::Delete method. The last line in the method is:
$c-forward('list');
Catalyst appears to be ignoring this statement. When I tried to delete a
book I got:
Coldn't render template file error - books/delete.tt2: not found
So, I tried creating an empty books/delete.tt2 template to see if Catalyst
just wanted to find a template file matching the method it was in before
performing the redirect. It then displayed the blank page instead of
redirecting to the list method. I'm sure there is something simple I
overlooked.
This might seem a little bit non-intuitive when you're just a beginner
at Catalyst, but $c-forward('list') won't cause Catalyst to render
your books/list.tt2 template. It will execute the 'list' action and
return, getting back to your books/delete.tt2 template.
In order to achieve the desired behaviour you could either issue a
redirect response (through $c-response-redirect($uri) ) or
explicitely set the desired template filename.

I think this really boils down to what you call application logic. Manipulating the database (i.e. what DBIx::Class does) isn't the kind of logic I was talking about. I meant actual business logic. This means things like validation (not that the other layers shouldn't validate data), access control, bridging your model and your view, triggering model actions, etc. IMO, the controller should be responsible for the higher level logic involved in an application while the logic contained in the model is a lower level (i.e. implementation details), usually data oriented, logic. -Nilson Santos F.

Good code in views: iterating an arrayref to generate a ul list, walking a data structure to generate a table, or walking a data structure to generate a graph image. I've found myself building somewhat fat views lately. Mostly, I've done it when trying to build generic widget thingies that might appear in different pages. By fat I mean resultset-manipulating views, but usually the manipulations are restricted only to the view-related aspect of them, though. This means stuff like ordering the resultset by some column (using order_by). I'm usually in doubt if this is indeed a good practice or if it should be done another way, but it sure makes things easier. Overall, I find it somewhat difficult to satisfactorily come up with a nice and clean design for generic widgets. For example, if you've got a login box that displays either login fields when the user is not logged in or some user information whe the user's logged in, you'll usually need some of HTML and some of Perl code. But it's really up to the view to decide whether it wants to display that widget or not, so the general controller actions should be widget agnostic. My main dilemma is: should I have a LoginBox controller that handles it and then forward from the view back to the controller while rendering (maybe issuing a subrequest?) or is it alright to have this sort of widgets with lots of code, possibly calling the model directly themselves? Is there an estabilished best practice for doing this? This is currently my main philosophical issue while developing using Catalyst. If someone could enlighten me regarding this subject, I'd appreciate it. ;-) -Nilson Santos F.

Re: [Catalyst] Program the logic
On 6/29/06, Brandon Black [EMAIL PROTECTED] wrote: The approach I'm attempting lately (and I haven't gotten it all working right yet...) is to make Controller base-classes that implement generic concepts for things like paging and sorting tables of data (complete with handling form args like ?page=3count=50 or ?sortby=foo:desc silently for the controller), which makes it effortless for the controller to apply those sorts of things to the resultset before its sent to the view. These bits of controller functionality are of course View-agnostic. It's View-agnostic but then the View still isn't Controller-agnostic. Actually, after some thought this might be the real question that'd solve my issues: how to properly decouple Controller from Views? I'll give you a real world example that's actually already in use in an implemented (but evolving) system. I've got a somewhat generic table widget. This table contains items that can be either active or closed. Sometimes the closed items should be displayed along the active, other times they shouldn't, but there's always a button show/hide closed items. It's currently implemented entirely in the View, since the controller IMO shouldn't really need to know if the closed items should or shouldn't be displayed. That involves doing bad things such as using c.param() from the View but it really was the only practical way (i.e. DRY) I could think of. So, any suggestions are welcome. ;-) They (the base controllers implementing these features) basically boil down to: Check for some standardized GET form parameters, provide some data to the controller in the form of a paging object or some DBIC sorting hashref stuff, and also directly set stash variables for the views to see, regarding paging and sorting. There are template includes that go along with these meta controller actions (displaying the 1 2 3 paging clickies and whatnot, based on those stash vars...). But how do you specify which actions are supposed to get the wanted behaviour? How do you handle pages with multiple resultsets being displayed? I think the convention could quickly become ugly. If you threw in some AJAX stuff in the mix it might even get uglier still. But I'd be *very, very* happy if you showed me I was wrong. ;-) -Nilson Santos F.

Although I'm primarily a Windows user, I can't really deny that the only one to blame in this situation is Windows itself for not having a way to easily build stuff yourself. *Every* other OS has this sort of things. Even those Linux distros that are completely targetted at the end user (such as Ubuntu) and don't come with a bundled compiler can have it easily installed with a mere apt-get install gcc. I find it rather weird that the suggestion of downloading a C/C++ development package in order to compile C/C++ code makes you laugh. It's like saying that downloading Perl in order to run Perl application makes you laugh. Clearly you've got a wicked sense of humor. I know... I'm supposed to do that all myself, and I guess I will, but for now I just don't have time. After downloading the setup file, it takes a double-click plus three aditional clicks in order to get it installed. I really can't imagine someone *this* busy. I mean I only want to finish my small app. My boss is going to split his gut when I tell him first I need to download a C++ dev package so I can install the application framework that actually is written in perl. Catalyst's written in Perl. Most of its dependencies also are. But some of them have parts written in C/C++. How do you expect to compile C/C++ code without a C/C++ compiler? I can't really figure what's the hassle about a 8MB download, some mouse clicks and about 1 or 2 minutes of setup time. I can't really figure out why your boss should even know or care about what you're using to get your job done. Looks like I'll be sticking to whatever Catalyst modules are available in PPM form for now. Not because I'm afraid of installing GCC, but because I can't imagine altering the roll-out environment to the point of installing UNIX emulation layers or C++ development packages just to put this app into production. There's no need of installing UNIX emulation layers. If your worries are deployment related, you could easily use PAR, which would pack the already compiled DLLs in a single package. Production servers shouldn't need this installed. Also, unless it's something absolutely necessary, I'd suggest you against deploying it in a Windows server. It's somewhat of a hassle to get mod_perl or FastCGI working correctly under Windows, the best I've got so far is running Catalyst under Apache::Registry, since mod_perl crashes when using PerlModule directives and I can't manage to even compile FastCGI and it's related Perl module and the built-in server becomes really slow if you need to support IE clients directly connecting thanks to the necessary -k switch. -Nilson Santos F.

The trick is to make the View smarter, which is a hard problem for webapps because of the degree of flexibility in styling required (ASP.Net has great shiny components, but any ASP.Net app looks like an ASP.Net app). Encapsulating the c.param bits in a TT plugin or three might be a good halfway measure.

Many strong advocates of MVC specifically try to leave business logic out of the database. What I see is that what Catalyst calls Model is just the Objects that map with the tables in the DDBB. And the logic of the application are developed in the Actions (in fact linked to the web application). You'll see that it's a little more than that (at least when you're using DBIx::Class - Class::DBI can't even be compared feature-wise nowadays). I know is difficult in practice to separate both worlds (logic from the presentation) but that is the false promise of the MVC pattern :). Not really. It's something somewhat straight-forward when using something like Catalyst.

Hate to impose on the members of the list, but can anyone point me in the direction of a good win32 binary GCC package that doesn't require Cygwin or other environments? the CPAN module was kind enough to download and install NMAKE from Microsoft itself (that was nice), when I upgraded it. Although it's somewhat like killing a mosquito using a shotgun, I usually install the Dev-Cpp open-source IDE for Windows. It already comes with everything you need to self-compile your modules (GCC/MinGW, etc) and works out-of-the-box. It's not a big download (8mb I think) so it's something pretty reasonable. The only manual configuration I remeber having to do is to add the GCC /bin dir to my system PATH variable. And then the CPAN shell from ActiveState will automatically configure itself and work using GCC. Since you've upgraded your CPAN shell using a version from the CPAN, I don't know if the magic still works and you might have to manually configure your compiler parameters (but that's a one time thing). -Nilson Santos F.

Perhaps you can forward this to the mailing list, as I am unable to reach it from my work (the mail server will not accept my relays.) Done. I'll answer your message without removing anything you wrote. I looked at the CPAN shell and it seems to be harder to use and less flexible than the PPM shell (Couldn't find an easy way find module descriptions like the PPM describe command, for example). Also, PPM's are pretty much guaranteed by the packagers to work with ActiveState Perl - I've been hesitant to install modules from CPAN due to fear of blowing up my Perl installs. Perhaps that's a foolish fear? I mean development is time intensive enough without debugging problems introduced by incompatible modules. Your discussion of the problem with Module::Install is a good example that I'd prefer to not have to worry about if I didn't have to. I also see that the CPAN shell is soon to be deprecated in favor of CPANPLUS in Perl 5.10 - Is it worth it for me to switch from PPM to something new that won't be applicable shortly? I really can't understand what you mean by flexible, then. I agree that it's a little bit easier to use the PPM shell but it's really *a little bit* (basically, at the CPAN shell you'll have to confirm the install of dependencies [even when you set your preferences to automatically follow them] while the PPM shell will do this automatically - I could argue this is one of the lack of flexibilities of the PPM shell). It really is a foolish fear, IMO. There's no such thing as blowing up your Perl install. The same sense of safety provided by the PPM shell regarding module compatibility is also available at the CPAN shell (i.e. version checking of dependencies, because that's pretty much the compatibility that is verified). I think this subject really can be summed up like this: the things that are problematic when dealing with the CPAN shell are usually not even available when you're restricted to the PPM shell. So, when you get an error when using the CPAN shell, probably that module (or module version) isn't even available at ActiveState's repositories. At least, you'll have a chance to fix it yourself and make it work instead of not even having the choice to do it. -Nilson Santos F.

Everything is tested at the development server. Granted, none of those do anything remotely related to Catalyst development. I don't really know if your environment is as extreme as what I described (it seems to be a little better since, apparently, you've got one environment per developer which is automagically set up through network shares), but as far as I can see Catalyst is a framework geared towards a different development mindset. Developers are expected to run code on their own machines and to keep everything is sync using SVN (or whatever makes it easy to do it).

In those newer versions, it already comes pre-configured, so you really won't have that much issues. Of course, you still won't be able to install modules that require compilation, such as Set::Object, but that's easily solved by installing GCC and then ActivePerl can also automatically configure itself in order to use it. The downside of using these newer and better AS Perl builds is that because of some... erm... issues in Module::Install pre-0.61 you won't be able to effortlessly install some things such as the newest (5.6902) Catalyst and any other modules packaged with Module::Install pre-0.61.
