I know zopeproject is an option, but I am looking for a recipe which does something similar. I'm working on one very slowly. My recent efforts to clean up zope.server are part of this effort. There's a good chance I'll have something by the end of the weekend. This will be a recipe, either similar to or an addition to zc.zope3recipes that let's you define a past-deploy based application with a zope3 application. My primary goal is to make it easy to select a publication component. This is a great news. I would love to see it in zc.zope3recipes package itself, may be zc.zope3recipes:wsgiapp or something like that. Here's an update. The first step is to create sane PasteDeploy app factories. zope.paste tries very hard to fit in with the current byzantine system. I appreciate the effort that went into this. :) I decided to go back to basics, especially since my main goal is to make it easier for people to control the publication component used. I've created application factories for zope.publisher and zope.app.publisher. I've released the zope.publisher version. It is very bare-bones. It is up to users to write a full publication object to go with it. Here's a simple buildout that creates a paster script: [buildout] parts = paster [paster] recipe = zc.recipe.egg eggs = PasteScript zope.publisher zope.server interpreter = py If you try this, you can create a very simple sample web server with the following config file; [app:main] use = egg:zope.publisher publication = egg:zope.publisher#sample [server:main] use = egg:zope.server host = 127.0.0.1 port = 8080 Which you can run with: bin/paster serve --daemon config-file start I'm working on an application factory for zope.app.publisher. This will: - Support the request-type selection framework in zope.app.publication. - Provide a derivative of zope.publication.browser.BrowserPublication that provides a hook for specifying an application root, other than using ZODB. - Provides optional support for loading ZCML before calling the publication factory. I've got a few details to work out and I need to write some tests. Maybe I'll release this next weekend, or the weekend after. After this, I'll be ready to add recipes to support it.

[Zope3-Users] Stability problem of zope3
Hi, I have jsut moved a production site from Zope2 to Zope3. I used zopeproject to download the necessary eggs and started my site using paste serve deploy.ini. Under moderate traffic however, the site stops responding soon. I have to regularily restart the server. When the site stops responding, 'ps -Af | grep python2.5' shows hundreds of process of paster running. And the process number increases with time rapidly, like: root 20230 18557 0 11:16 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20231 18557 0 11:16 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20237 18557 0 11:17 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20248 18557 0 11:17 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20249 18557 0 11:17 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20250 18557 0 11:17 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20251 18557 0 11:17 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20252 18557 0 11:17 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini root 20284 18557 0 11:18 ?00:00:00 /usr/bin/python2.5 bin/paster serve deploy.ini Looking into z3.log, I found lots of alarming error messages like: 2008-03-03T11:01:57 INFO paste.httpserver.ThreadPool No idle tasks, and only 0 busy tasks; adding 5 more workers -- 2008-03-03T11:01:58 CRITICAL ZODB.DB DB.open() has 253 open connections with a pool_size of 7 -- 2008-03-03T11:01:58 CRITICAL ZODB.DB DB.open() has 254 open connections with a pool_size of 7 -- 2008-03-03T11:01:59 CRITICAL ZODB.DB DB.open() has 255 open connections with a pool_size of 7 -- 2008-03-03T11:01:59 CRITICAL ZODB.DB DB.open() has 256 open connections with a pool_size of 7 -- 2008-03-03T11:01:59 CRITICAL ZODB.DB DB.open() has 257 open connections with a pool_size of 7 -- 2008-03-03T11:02:35 INFO paste.httpserver.ThreadPool No idle tasks, and only 0 busy tasks; adding 5 more workers -- 2008-03-03T11:02:36 CRITICAL ZODB.DB DB.open() has 258 open connections with a pool_size of 7 -- What's wrong with my installation? For your information, the following related components are installed: PasteDeploy-1.3.1 Paste-1.6 ZODB3-3.9.0_dev I am running these with Python2.5.
