Mako template loader for non-dotted template names fail to init

I know I may be asking a bit too much but you seem to be involved in tg dev quite a bit so I try :)

Could you write a tg test that exhibits this problem? This is located in:

tg/test_stack/rendering/test_rendering.py

Florent.

I don't have a clear idea on the solution we need to apply here. Need to think a bit...

Would a single "compiled_dir" be sufficient or would it fail if there are more than one template directory?

This is because the test config doesn't match the standard config. Compare this:

with this http://trac.turbogears.org/browser/trunk/tg/configuration.py?rev=6276#L174

where the self.paths is setup. In configuration.py for some reasons a list is created for template paths

According to the doc there can be multiple template dirs (this is what 'directories' is for), and one single compiled template directory (module_directory).

I guess the fix is to still use directories=self.paths['templates'] but to use module_dir=self.paths['compiled_templates'] which must return a single directory that is writable by the webserver

we will need a new deployment config option to indicate a directory where the web server has write access to put the compiled templates. What about:

templating.mako.compiled_templates_dir = somedir

in the app:main section of the .ini files. If no option is found the server will try to specify the first template dir as the compile dir so that development install do no have to bother about setting this option manually.

what do you think?

That sounds fine !

Added the option in r6329 of tg.devtools so that the default development.ini templates give indication of the existence of this option.

putting this ticket in the documentation component so that it can be found during next Doc sprint...

I would like to reiterate (as the OP stated) that this functionality is broken unless you set use_dotted_templatenames to False. This is very disappointing. Please see #2395 for further info.
