zope_conf in paster config can only be global

[Kim Luong]

Michael Haubenwallner was kind enough to add zope_conf parameter to the paster config so that you can specify the location of the zope.conf. However, it only got added as a global parameter. This means that you can't specify different zope.conf for different applications. We would like grok to be able to handle different zope.conf for different applications. We have patched grok project so that it works for us and request that you roll our patch into subversion. svn diff follows signature.

Thanks,
Kim

Michael, can you look into this?

[Uli Fouquet (uli-gnufix)]

As we currently try to move startup.py away from application code itself I am afraid that a term like ``${package_directory}`` runs us into trouble.

Beside this I (yet) do not completely understand your use case. Could you provide some examples how you call different applications with the patch applied?

[Michael Haubenwallner (d2m)]

I think we really need to reorganize that part of app startup.

Martijn Faassen already suggested to move startup.py into a package on its own (like grok.startup) to move it out of app template creation process. I am working on this, hope you can join me.

Michael,

I apologize for such a delayed response. In any cases, I'd be happy to help in any way I can. I must make a disclaimer that I'm very much a newbie. Let me know what I can do.

Thanks,

Kim

Michael -

maybe _you_ can tell me the use cases Kim talks about. Wouldn't it be sufficient to create alternative ini-files for different zope-confs?

Anyway, I'd be happy to assist with the 'external' startup.py. We can discuss this in the other thread:

added the local_conf option to the new grokcore.startup
