Re: [Catalyst] Graceful handling of database failure
You can use DBIx::Class with DBIx::RetryOverDisconnects as DBI handle and you will never got db server away message (it will reconnect as long as required until database is up and no queries and transactions will be lost). 2008/6/18 Mitchell K.

Odd thing was, when I added the Private attribute as per your original
example, it broke the app somehow. I'll look at that some more.

J,
Thanks for the help. I tried the approach you suggested, but it's not
working for me. Yes, I am using DBix::Class, and yes, it does seem to
do The Right Thing and somehow throw a $c->error that makes it out to
the log.
I wrote an action similar to the one you suggest ( code attached below
) and threw a bad username into the database connection string.
Watching Debug output, it appears the end action is never called when
the error happens. The debug output looks like this:
=
You can connect to your server at http://myapp.com:3000

=
Since /end is never called, the error handling never happens.
Is there some other way to tie into the error handling, or am I
missing something? Following is code I'm using for end action:
Thanks,
/Mitch
=
sub render_end : ActionClass('RenderView') {}
sub end : {
# The default error handling of Catalyst gets pre-empted here with our own,
# unless the app is operating in debug mode.
# First, we forward to the standard renderer end action. After, we
# check for errors. If they exist, we handle the errors and clear them from
# catalyst, but add them to the stash.. Then we override the template
# to use error500 and display an error by forwarding back to the renderview
# a second time.
my ( $self, $c ) = @_;
$c->log->debug( 'On a DBIx::Class Connection error this statement
never happens' );
$c->forward('render_end');
return unless @{ $c->error };
# If we're running under debug mode, allow default error handling
# and stack trace. Otherwise, override error handling
return if $c->debug();
# Collect and clear catalyst's error stack, creating a copy into stash
my @errors = grep { 1 } shift @{$c->error};
$c->stash->{errors} = [EMAIL PROTECTED];
for my $error ( @errors ) {
$c->log->error( $error );
}
# Re-process final rendering w/o the error stack
$c->stash->{template} = '500.nonav.tt2';
$c->detach('render_end');
}

Re: [Catalyst] Unkown error
This is just a "error somewhere". In 5.10 some of standart perl runtime
exceptions might cause this "Unknown error". You just have to find the error
manually and fix it.

Re: [Catalyst] Unkown error
I've been getting them too... I've been bracketing them with BEGIN {warn
q{#27};} type code and narrowing down the location. In each case there was
some stupid typo or something in there.

I have the original .eps file of the Catalyst logo, you will find it at: http://www.external.shadowcatprojects.net/data/common/images/catalyst logo.eps It can be scaled to pretty much any size in a IMP but if you would like it as a png/gif/jpg of a set size/quality and do not have the time/inclination to do it just ask and I will do this for you and post it to the same location for retrival.
