I took a quick look at C::P::Cache and I don't think it is possible to use

stores the text somewhere under its own package name in a hash. To use a
cache backend here would mean creating a module around L::M::L which alters
internal data whereas this new module would depend on the current L::M::L
module version. I don't think this would be good.
So from my point of view the best way would be to reload the lexicon data
once it has changed. As this is not possible without manually restarting
apache, this leads me to reloading the lexicon after the database contents
has changed within each apache client on request start (before any lexicon
text is requested). I could initiate this within an auto sub in Root.pm,
but this seems very ugly. I guess a new plugin (like
C::P::I18N::DBI::Reloader) would be good. What do you think?
Why cant you just do a:
# ... incrementally add new lexicons

[Catalyst] Production session issue - commercial support inquiry?
Have you looked at trying to replace the seed generator for the session (or
if you have, have you verified it actually has enough entropy for your
load)? I could imagine given enough preforks and hitrate that the default
seed could allow doe some collisions. I would expect it would take a very
high hit rate -- if so you may need to pull more than 20 bytes of random to
get enough entropy. Examples from the POD below:
In the hopes that those combined values are entropic enough for most uses.
If this is not the case you can replace session_hash_seed with e.g.
sub session_hash_seed {
open my $fh, , /dev/random;
read $fh, my $bytes, 20;
close $fh;
return $bytes;
}
Or even more directly, replace generate_session_id:
sub generate_session_id {
open my $fh, , /dev/random;
read $fh, my $bytes, 20;
close $fh;
return unpack(H*, $bytes);

[Catalyst] Re: Production session issue - commercial support inquiry?
Sorry,
Wanted to clarify a few things. I realized there may be a few cryptonuts
on this list and I want to avoid a flame. The session_hash_seed is
actually not a seed generator -- but a plaintext generator. Below, I am
talking about collisions of the plaintext and therefore the digest -- not
digest collsions on unique plaintexts. Given that the default is:
sub session_hash_seed {
my $c = shift;
return join( , ++$counter, time, rand, $$, {}, overload::StrVal($c),
);
}
and the generator is
sub generate_session_id {
my $c = shift;
my $digest = $c-_find_digest();
$digest-add( $c-session_hash_seed() ); #note the seed is actually
plaintext;
return $digest-hexdigest;
}
and that the OP is running on a prefork system, most of the join on the
seed above can theoretically overlap on a high hit, fast cycled/forked
system -- resulting in potential overlaps of plaintext and therefore session
id/digest. Depending on how many children and the fork depth (runs per
fork) this could situation be exacerbated.

To divert this a bit, are you -really- sure you want
to
store them in
a database? Storing large files in a database is not
going
to be
ideal, as you'll lose abilities to replicate the
files
in a separate
policy from you DB, etc.
Yes, but OTOH i gain the ability to back up everything at
once, and move onto a different machine or even platform
without having to worry about two seperate place.
But this is a holywar that others have fought about for a
long time, no need to, ah, replicate it here ;-)
But to answer your question, the uploads are this
object:
http://search.cpan.org/~mramberg/Catalyst-Runtime-5.
7014/lib/Catalyst/Request/Upload.pm
You can then just do $db_record-contents(
$upload-slurp );
Yes, i saw the upload object but most of it looked like
filesystem stuff, so i wasnt sure what to do then. So if i
want to create a new record, for lets say a table called
'image' and a blob field called 'image' with
a 'mime_type' description, i just do something like
my $new_record =
$c-model('MyDB::Image')-create({ image =
$upload-slurp, mime_type = 'application/pdf'
});
and thats all i have to do? Wow thats easy!
I did just want to report that i did this and it worked perfectly.
My actual line was:
$c-model('MyDB::Image')-create({ image = $upload-slurp, type =
$upload-type });
I figured that i should use $upload-type so that just in case i
later want to upload gifs or something i wouldnt have to change code.
Be careful, upload-type Returns the _client-supplied_ Content-Type. You
may want just a bit more code around that to verify type and the fact that
the client actually submitted a mime type.

This forces the save promt and also makes sure no-cache is set so that a
failed download does not leave the user with a partial file.

2) Actually send the data.
In your original post, you hand-waved sending the data. A number of

C::Action::REST uses ActionClass('REST') to specify the class for
the action. And with a custom request class, has a custom dispatcher to
dispatch based on the request method.
Your example above does not use ActionClass. Were you suggesting that
these XMLRPC actions have their own action class, and if so how would
the actions be setup then?
I would think the Catalyst approach would be something like this:
sub widget : Local ActionClass('XMLRPC', 'widget.get' ) {
There's more than one approach, of course.
My current approach (w/o versioning) is to have a custom dispatcher
type (which I push onto $c-dispatcher-preload_dispatch_types). I
also have a custom HTTP::Body type to parse the XMLRPC payload. Once
the XMLRPC method name is known from the request the dispatcher
searches for the matching action.
But, I do like the approach of matching the action, and then using
$controller-can to try and find an appropriate version as you
suggested.
By the way, my assumption is I would have the entire XMLRPC API
versioned. I asked about this on the XMLRPC list and it was
recommended that instead I version individual methods. That is, have
separate method names that include a version:
widget.1.get
widget.2.get
etc.
which would make the Catalyst part very simple, but I'm not sure I
like that idea of each method having a version in the method name.
Bill,
Icky, I think the API should be versioned -- not methods. What if
the methods across versions are not compatible (widget1 output used with
foo2) versioning the api forces all methods to be used with their tested
and versioned partners. When you have 30 or 40 different revisions and
developers start relying on mismatching methods from different versions
that seems like a headache waiting to happen.

PM:
I'm using Cat with a pretty standard configuration of :
Catalyst::Plugin::Authentication
Catalyst::Plugin::Session
Catalyst::Plugin::Session::State::Cookie
Catalyst::Plugin::Session::Store::FastMmap
to handle login and session management. My login code looks like this:
my $u = $params-{username};
if ($c-authenticate( { username = $u,
password = $params-{'password'}
} )){
my $user = $c-user;
$user-last_login(DateTime-now);
$user-update();
$c-response-redirect( $forward, 301);
} else {
# login failed
$c-stash-{login_failed} = 1;
}
What I'd like to do is check if this user is already logged in at some
other computer, and deny access if so. I guess that means :
1. checking whether there is an existing session associated this username
2. Being sure that the associated session is cleared when the user
hits 'logout'
I did a quick search and didn't get anything on the list - any quick
clues about the easy way to do this, before I start digging into the
guts of the plugins to see how?
many thanks
Daniel,
This is actually a pretty hard problem -- there is no right answer.
What if the user clears her browser state while using the site? Leaves the
computer and browser on at work then tries to log in at home on a different
computer? I think you can gain most of the lockdown of 1 session per user
if you just track user activity over a X minute period. for instance every
time a user hits your app add a record that is attached to the user account
in the db (src ip, session number, other relevant info). Then do (either
inline or if it is too costly, via cron) a check on those entries that
looks for multiple IP/Sessions or whatever you define as multiple users
(given that http is stateless there really is no _safe_ definition). If
that process detects usage over your threshold, disable (temp or
permanent) the account. The same process can clean up entries that are
outside of the time window that you want to look at.

Hello!
I need a help on building a model for user that has a permission to edit
other users that were created by this user or any of his children,
grandchildren etc.
(difficult sentence, I know)
To make this a little more understandable here's my database table:
- user_id
- username
- password
- various other data such as fname, lname, address etc.
- parent_id
Column parent_id has a value of user_id that created one user.
There is also
a superadministrator with parent_id '0' that can edit everybody.
Now I would like to build a model that I can use in my controllers like:
if ( user_id is child,grandchild,gradgrandchild of logged in $c-user
) {
# has permisson to edit
} else {
# doesn't have a permission to edit
}
Example:
- superadmin
|__- foo
|__- bar
|- john
|__- doe
In this example:
- superadmin can edit anybody,
- bar can edit john doe
- john can edit only doe
- foo can't edit anybody since he has no children
And there can be unlimited levels of users...
There is no problem with permission to edit first child since I can
just compare
logged in user's ID with edited user's parent_id but when edited
user is grandchild,
grandgrandchild, (grand * n) child of $c-user then I need some kind of
model
to return true/false value.
I've never done that and I am also new to Catalyst so any help would
be appreciated.

Re: [Catalyst] Upload progress meter
Bill Moseley [EMAIL PROTECTED] wrote on 02/29/2008 01:30:38 PM: So I have a file upload page and an ajax-updated progress meter. Not unlike the UploadProgress plugin. The progress meter works fine while transferring the file. There's also some processing that happens to the file after the upload is complete (and before returning the response) and during that processing I update the JSON that is returned. But, the progress meter isn't showing that post-upload status. My guess is once the browser has sent all the file data that it stops processing the ajax requests. Can anyone confirm that's what is happening? This depends, if you are submitting a passthrough form for the upload directly the page will reload after the upload is done. If you are doing a ajax submit this could also be the case depending on how your framework handles the form post. If you are posting to an iframe this problem is most likely in your js update progress event loop. It would help if you strip out the offending code blocks/template and js and post. Another question about upload progress meters. A seemingly common way to handle the upload progress is to submit the form in an iframe. Are there some browsers that require that? That is, won't work with the UploadProgress method of submitting the form and continuing to run the ajax to check the progress? I have been bitten by this -- safari seems to _not_ allow updates to dom while a form (with upload) is being posted unless you post to an iframe. I am sure there are others. I'm not a fan of the iframe method. The examples I've tried online are often poorly implemented. A few that I tried failed to stop making ajax requests after the file was uploaded. Well the YUI framework upload progress does not use an iframe (directly at least -- it may do so in the js code) and works on safari. The problem is this uses a flash part for file select and upload so it may not be acceptable to you. My goal is to get a very flexible (bulletproof) upload progress plugin. IMHO it should support fall back to normal form post if js is not available and work across all browsers out of the box. Also I would like to extend it to allow multi file select ala js or flash via config. I am still digging into the current uploadprogress plugin to make it work for my needs, but I would like to get it upadted to just generally work (to be fair it does work for most cases right now, just not on specific browsers such as safari). A secondary problem I have is that http uploads do not support files larger than 2gb (with some very limited exceptions based on browser/server combos). I would have loved to see yui's flash based uploader work around this somehow but I guess there is no way to do so yet. -Wade -Wade ___ 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/

[Catalyst] RFC - Catalyst::Plugin::UploadProgress (changes to accommodate safari)
I am looking for comments from people whom use this plugin. I have
had some issues getting it to display the upload progress bar realtime with
safari. After a lot of digging around it appears as though safari does not
allow you to update the DOM while a form containing a fileupload is posted.
Actual usage shows the progress bar for a flash (or not even) right before
the final page reload happens from the form action url.
The solution I have found and seems to test across all browsers
(ie,ff,safari, opera) is to (yes I know i hate them too) use an invisible
iframe in the form and set the form's target to that iframe. The jmpl js
needs to be changed to redirect to the action url to achieve the same
redraw of the screen that happens after the non-iframe-target-hacked
version.
My questions are:
Has anyone else seen these issues, or found any other way around them?
Should I just submit a patch for pod describing the issue and workaround
for safari OR change the pod, startEmbeddedProgressBar to accept a target
final target argument and jmpl to allow for the jump?
See below for a working (safari,ff,ie,opera) example modified from the pod
(without the jmpl/js mods).

You mean without the context object. :( Yes, that's what I want. Can't the context object be accessed in MyApp.pm? Thanks. Octavian Currently MyApp.pm *is* the context object. The problem is Catalyst has no idea of the hostname until it sees the request headers - you can have multiple hosts point at the same Catalyst app. Only you know what the hostname is - so you'll have to set it in the config. -ash Not really, the http request also includes the clients version of the host it is requesting from. This is how virtual servers work (where one http process serves different data based on the hostname the client is requesting). $c-req-header( 'Host' ) provides the information needed from the context object, but is unavailable to MyApp.pm. cookie_domain setting in Catalyst::Plugin::Session::State::Cookie needs to be set to reflect the requested hostname in this case else the browser will not set the cookie nor include it on round trips to the application if the requested host/domain is different from the host that Catalyst believes it is running as. I believe a workaround for this issue is to leave the cookie_domain setting unset which I believe will produce a cookie that is not stating its domain and the client browser will treat as locked to the requested host's name for the domain. So if you want the cookie to be set on the client without worrying about the hostname requested don't set the domain_name or set the domain_name to the common domain for all hosts. -Wade ___ 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/

This makes it important not to introduce new modules, or upgrade existing modules, without an extensive testing period to make sure it works with all existing applications. The trouble with this is that it is easier to keep stable (or work around existing known problems) by not installing anything new. Sure - but as I understand BBC is their client and this policy makes the life of BBC programmers pretty miserable. Yes, it does make for a pretty frustrating work environment sometimes and although Siemens should be working for the BBC it often feels like the other way around. Seems poorly thought out. There's one point that hasn't been stressed that I think is very important. The problem isn't technical, it's commercial. The BBC have outsourced some work to Siemens. It's certainly the case that to maintain stability Siemens would need to do testing but I imagine the main factor from their point of view is that *it provides extra revenue*. I don't know about this contract but on another I'm aware of they like nothing better than having the client request a new feature :) Without knowing the reasons why the BBC chose to outsource and the contract details, it really isn't possible to say whether it's a sensible arrangement. Sure it makes developers' lives more difficult, but that's not the main goal to be optimized.

While I mostly agree with Matt's take on unix/linux issues -- I will give my support to Cent/RH here. It is true, they have had some missteps with perl in the past. Those tend get resolved fairly quickly. The perl speed issue listed above is fixed in current patches. RH/Cent has some very undeniable advantages over ubuntu/suse/flavor of the day. Some advantages likely to make a difference in corporations are tight partnerships with dell and other server vendors (read tightly coupled hardware support and updates), tight relationships with commercial software vendors (pick 5 software packages that run on linux from different vendors chances are the common supported platform will be RH and therefore CentOS). It is also not uncommon to build your own kit for webserver/perl/mysql etc for production servers no matter what distro you choose -- and run that in parallel to the distro's build. It makes sense to control the bits that run your applications. In general, when it comes to linux distros, my belief is that issues you have with distros can generally be pinpointed down to the administrator (myself included).

Re: [Catalyst] MyApp::C::PageHooks - thoughts ?
Matthew Pitts [EMAIL PROTECTED] wrote on 10/29/2007 03:24:10 PM:
I wanted to get some thoughts on something a little different that I'm
doing...
What I want to to have is Controllers that are temporary (i.e. date
sensitive) that represent a particular promotion that's running on a
site. This promotion may need to affect different areas of the site, but
I don't want to have $c-forward calls like the following everywhere
that I need the Promo's code to inject stash data.
$c-forward('Controller::Promos::Foo', 'some_action')
So, I decided to do a form of hooks within my app so that any given
controller can affect the stash for a defined set of hooks.
Below is the first run of my code to implement this. Basically, I
override Controller-register_actions and run through all the
controllers looking for C-config-{pagehooks} and build a local hashref
containing the hook definitions.
Then, in all the places throughout the app that are defined as
hookable I just do a:
$c-forward('Controller::PageHooks', 'run_hook', 'hook_name', [ 'arg1',
'arg2' ]);
and it just works.
The main advantage with is that I can remove the promo's controller and
don't need to change any other controllers. I can even get my design
guys to code their templates in such a way that when the promo expires,
every place on the site affected by the promo magically goes back to
pre-promo look-and-feel.
Any thoughts on my level of sanity here?
Why not just store promos in the database and have a static controller that
acts on active promos? No changing application code for the promo. easy
to do future promos too as you can have an epoch start and end time for the
promo in the db tables that the controller takes into account.
