[Zope-dev] Re: zope.sqlalchemy, integration ideas
Martijn Faassen wrote: Laurence Rowe wrote: We need to differentiate between the interface for session configuration and session usage from an application. Session configuration? I'm talking about engine configuration. A session doesn't need to be configured, except with a session, I think, which the ScopedSession machinery allows you to do. If you can make the engine be the right one in the appropriate context it should only be a matter of configuring the session in that context. For session usage I think it is fairly simple. We should define an ISessionContext interface such that: class ISessionContext(Interface): def __call__(): return a session in this context A future version of collective.lead could implement an ISessionContext. Client code however should have a cleaner interface, a plain ISession. This is accessed through a lookup on the context, translated into a simple adapter: def session_adapter(context): session_context = queryUtility(ISessionContext, context=context, default=None) if session_context is not None: return session_context() This will allow application code to do something like: session = ISession(context) ob = session.query(MyClass) I don't understand what the point of doing this is. What is 'context' here? Why am I adapting context? My context is normally thread-local and implicit. This has been the way to approach context in Zope 3 for a long time now (though explicit context can still be passed through getUtility it's rarely done). And again, I think *engine* should be in context, not sessions. ScopedSession, a standard SQLAlchemy mechanism, should be used for session context-specific session access. Why the introduction of ISessionContext and ISession interfaces, and an adapter lookup that looks up a utility and then *still* I haven't seen the code that actually configures the engine? My aim was to try to stick to SQLAlchemy patterns for solving this problem where we had no reason to diverge from them, and our use case, I take it, is what ScopedSession was designed for. [snip] session.remove() is not important, sessions are closed by the zope.sqlalchemy datamanager and closed sessions are recyclable. That's good to seee confirmed. I thought it was that way reading the code, but I wanted to make sure. Presumably the session object would be referred to by a volatile attribute on the local utility and the session would be GC'd along with the local utility object itself. Are you talking about a persistent local utility? Which one? Would this mean that the session needs to be re-created each time the ZODB swaps out the object with the volatile attribute? I thought the session was intended to be recreated each request, does it make any sense to cache them between requests? Table creation is another matter that I don't think too important. I think it's important to get it right for Grok. We're using the declarative extension and still want to support hand-created tables as well. There are various scenarios surrounding table creation, either not doing it at all ever, or spelling them out by hand in Python, or by inlining them into the classes as with the declarative extension. Implicit creation of tables seems wrong, instead tables should only be created explicitly, by the use clicking a button in the zope web interface (or automatically on adding an application). Automatic on adding an application is a good point to do it, as that way we don't bother the person who creates the application too much (first create the database.. then install the application, then go to this screen and create the tables). There's another feature to automatic table creation though: when I'm developing and I don't care about the data yet, all I need to do now when I change the schema is throw away the database and create it again. I found this very convenient while developing with collective.lead. We need to have something that is at least as convenient for this use case (common during initial development). An exception to this is sqlalchemy in memory databases, which must be created on first access. Don't know what these are? Those with a url like 'sqlite://:memory:' Session configuration would be somewhat similar to collective.lead currently (registering one as a local utility). Before we talk more about session configuration, please explain why we're not talking about engine configuration. :) Engine configuration is a subset of session configuration. You cannot have a single ScopedSession for a package if you want to have multiple instances of that application. We must work with unbound metadata if we have this goal. That implies that we must use bound sessions, a session associated with a particular engine (actually it could be more complex than this, you can associate particular classes/tables with particular engines within a session). The simplest way to achieve
[Zope] buildout for plone2.5: paster creates bad zcml
Hi there,
I try to use paster for a plone 2.5 site.
this is what I have done:
paster create -t plone2.5_buildout plone2
executed bootstrap and buildout
then in src:
paster create -t plone2.5_theme x.y
which I added to the buildout.cfg like so:
[buildout]
...
eggs =
elementtree
x.y
develop =
src/x.y
...
[instance]
...
zcml =
x.y
when I then start the new instance, I get the following error:

what can I do to fix this?

Re: [Zope] buildout for plone2.5: paster creates bad zcml
for the record:
I found a way to fix this by using a newer five versin.
I added:

in the buildout.cfg.
it would be much nicer, to have the buildout recipes fixed

Re: [Zope] Multithreading sessions
Jens, Thanks for your input. Unfortunately, I am out of the office this week. When I return I will be trying to resolve this issue. I don't believe it has squat to do with my Database at all, so I will be setting up some scenarios where I am making simultaneous requests, requiring no DB access. I will echo the data to my screen, hopefully I will see an interwoven jumble of characters as my web server is sending text simultaneously to multiple clients. If I don't see an interwoven jumble of stuff representing the various threads, then my problem is more fundamental than DB contention. I appreciate everyone's help.

The traceback above seems to be about something going wrong within the TAL interpreter which is probably why we don't see any further traceback info. Shane had added lots of __traceback_info__ and __traceback_supplement__ declarations to the older code such that the tracebacks were very informative ... unlike the traceback above. As far as I can tell, the code in zope.pagetemplate and zope.tales still has the same traceback information that Products.PageTemplate had. zope.tal, which contains the TAL interpreter, doesn't have any traceback supplements, but then again, Zope 2's TAL package doesn't either. To conclude, I don't think there's a step backward at all. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
