[Catalyst] Catalyst::View::TT - strange caching annoyance
Hi!
I found an interesting bug in Catalyst::View::TT. Catalyst caches wrong
templates even if I do not use caching.
I created a fresh application with catalyst.pl, added some templates,
modified the MyApp.pm according to my needs, and finally I added a TT view.
After fireing up the application with './script/myapp_server.pl -d' I
checked if it works. It did. Then I modified the Display.hu.tt template
to get a syntax error (I did this with removing the [% END %] block of
the IF conditon.
When I called the default handler again, of course I got error:
---
[error] Coldn't render template file error - parse error -
Display.hu.tt line 9: unexpected end of input
---
After this I put back the [% END %] block and reloaded the page,
catalyst sent me an another message:
---
[error] Coldn't render template file error - setup: not found
--
After restarting the cat app, the same template works again.
Sorry for this kind of bugreport... :)
Bye!

Commands to reproduce this:
catalyst.pl MyApp; cd MyApp
mkdir root/master
mkdir root/include
cat root/Display.hu.tt EOF
[% INCLUDE master/popup.hu.tt %]
[% BLOCK default %]
[% INCLUDE calendar %]
This here is the default with an IF statementbr
[% IF 1 == 1 %]Works[% END %]
[% END %]
[% BLOCK setup %][% END %]
EOF
cat root/master/popup.hu.tt EOF
[% INCLUDE include/common.inc %][% PROCESS include/common.inc %]
[% INCLUDE setup rows=5 %][% PROCESS setup %]
[% INCLUDE default %]
EOF
cat root/include/common.inc EOF
[% BLOCK calendar_init %][% END %]
[% BLOCK linker_search %][% END %]
[% BLOCK calendar %][% END %]
EOF
cat lib/MyApp.pm EOF
package MyApp;
use Catalyst::Runtime '5.70';
use Catalyst qw/-Debug ConfigLoader Static::Simple DefaultEnd/;
__PACKAGE__-setup;
sub default : Private {
shift; # sorry cat command swallows dollar sign :)
shift-stash-{template} = 'Display.hu.tt';
}
1;
EOF
cat lib/MyApp/View/TT.pm EOF
package MyApp::View::TT;
use strict;
use base 'Catalyst::View::TT';
1;
EOF
rm lib/MyApp/Controller/Root.pm
./script/myapp_server.pl -d

Re: [Catalyst] Catalyst::View::TT - strange caching annoyance
However, TT should update its cache automagically (keyed on mtime) -- even if you use the full compiled (to-disk) template cache. Questions: 0. What version of TT, Catalyst, and C::V::TT are you using? (Find out with perl -MCatalyst -e 'print Catalyst-VERSION', etc.) 1. Can you provide us with a case where regular TT correctly refreshes the template, but C::V::TT doesn't? 2. If not (i.e. regular TT breaks too), do mtimes work on your system? My guess is that something is wrong with your system; outdated TT, buggy filesystem, etc. It's very possible that I'm completely wrong, but my templates are fully cached (on disk) and do update properly. I haven't tried the code you sent because it's too complicated and is certainly not the minimum required to reproduce the bug. Does: cat root/test.tt2 EOF Hello, world? EOF change when you apply - Hello, world? + Hello, world! This changed! Something like that would be much simpler for me (and others) to test. Thanks!

Re: [Catalyst] Catalyst::View::TT - strange caching annoyance
Good find. The whole complicated [% BLOCK %] business that I was complaining about was actually the problem. I admit to never having used [% BLOCK %], so that's why I didn't run into the problem.

Do you put anything that will be INCLUDEd or PROCESSed into separate files? I tend to put all related small chunks of HTML, Javascript, etc into separate, named BLOCKs in a single .tt2 file. And for anything I'll be using on a regular basis, I make them MACROs instead.
