[Zope-dev] TAL i18n breakage in 2.7
Hi, Zope 2.7 introduced a change in its translation interface.

[Zope-dev] Zope 2.7 memory behaviour
Hello, I´m trying to find a memory leak in a zope appliction and started to test how zope memory consume behaves basically under load. The current result is: Zope constantly consumes more memory. The testcase is: 12 http clients request constantly request the same page template (it does not contain any tal statements and only 10 lines of HTML) in a simple folder. The increase is about 50 - 100 kb / minute. I´m using Windows 2000 as server platform. The database cache and debug information on the control panel seem allright. Now I wonder if there´s basically a problem with Zope 2.7? Has anyone made the same experience? Or an explanation why this happens?

Re: [Zope-dev] Core Dump (Zope 2.7, Python 2.3.3, FreeBSD 4.5)
We have a report for Zope 2.7 about an object magically turning into None (1 or 2 weeks ago). A similar problem was discovered recently by a colleague. I started analysing it today. It turned out that objects are non-deterministically converted into None. I have seen such behaviour in the past (with an old Python version). Later, it turned out to be a memory corruption problem in this Python version. Memory corruption can also cause death with a core dump. It is well possible that our problem is caused by my Zope modifications or other (third party) C level extensions. But, there might also be some lingering problem in Python2.3.3/Zope2.7. I will thouroughly investigate our problem within the next week and report back. -- Dieter ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] [ZConfig] import inhomogenous
Fred Drake wrote at 2004-2-18 15:01 -0500: ... importing schemas ... [DM] A use case is the import of the section types defined in Zope.Startup.zopeschema.xml for other ZEO applications that require access to the same ZODB database(s). It is far more convenient to access this schema via package+file than an URL. [FD] Is there some reason not to simply move the section types to a schema component? That seems more in the spirit of making the schema modular. This would be an alternative. However, the change is much bigger (measured in patch size) than my ZConfig patch. ... I've not read the patch yet, so I'll ask: what's the point of the type attribute? I propose to make the type of the imported object orthogonal to the location where the object comes from. This means, you have the following options * schema component from package * schema component from url * schema from package * schema from url The type attribute specifies whether you want to import a schema component or a schema. You could do without this attribute when we would look into the resource and determine from the content what it is. Should it be an error if the type doesn't match the top-level element of the resource? If only advisory, is it actually useful? Currently, a wrong type lead to a ConfigurationError. Thanks for thinking critically about ZConfig. I am using it and see places where I am forced to either make significant changes or have significant code (either schema or configuration) duplications. I hate code duplications... This time I use it to automate processing Shane's QueueCatalog's. The corresponding script needs the same ZODB configuration as Zope (a complex DBTab configuration with potentially many storages). Therefore, its schema needs the zodb_db definition defined in Zope's schema. It is quite nice to use ZConfig.

Sorry, I haven't been following this thread, but I will note that I've seen (repeatably) in my test Zope environment this behaviour. This is probably unrelated though... For me, the situation comes about when I am loading up my fresh (ie. clean ZODB) test Zope with a thousand users. While the load script is running (it runs on the command-line and goes TTW using urllib to register the users) if I access a page which summarises all users, I *sometimes* get None for some of the users. The page uses a Catalog to find basic user info, and sometimes uses getObject() to find the real user object. The getObject() appears to return None sometimes. Once the load is complete, I don't see any errors. So I blame some mechanism failing under load.

I don't think anything relevant changed in the Python core, apart from special-casing regexp tests on FreeBSD to have ever-lower expectations. Googling suggests that the BSD 'ports' collection (I have no understanding of what that means, though) added a Makefile option WANT_HUGE_STACK_SIZE which, if specified, causes FreeBSD to give threads the same stack size most other OSes give by default.

This is still something that have to be tested to see what works best. Managing the work with the listen() backlog instead of Medusa's request queue has the benefit of being less resource intensive (Medusa doesn't have to do anything). If Zope is behind a HTTP accelerator/surrogate or load balancer, the surrogate's connect() should fail if the listen queue is full, and it may return 503 anyways (not tested).
