[Zope-dev] Problems with Zope 2.8 on FreeBSD (was Re: Problems with PageTemplates on Zope 2.8)
I have an application called the Issue Dealer which I'm porting to Zope 2.8. However, whenever I try to access a PageTemplate which makes use of a page template macro it just hangs and consumes all available CPU. Any ideas what could be wrong here, or how I could debug it? Does the server or the client hang? It's the client that's hanging. The first time I tested it, it was as a simple Zope instance. http://instance/manage worked fine, but accessing an Issue Dealer instance (http://instance/stuff) didn't work. Now when I try setting up a ZEO server/client version 2.8 with python 2.3.5 on FreeBSD 5.4, the server hangs even when I try to access http://instance/manage. http://instance/manage_copyright works fine however. -Morten begin:vcard fn:Morten Petersen n:Petersen;Morten org:Nidelven IT adr:;;Postboks 923;Trondheim;;7409;Norway email;internet:[EMAIL PROTECTED] title:Project Manager tel;work:+47 45 44 00 69 tel;cell:+47 45 44 00 69 x-mozilla-html:FALSE url:http://www.nidelven-it.no version:2.1 end:vcard ___ Zope-Dev maillist - Zope-Dev@zope.org 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] Re: Windows Builds
[Tim Peters] Anyone else run on Windows routinely who's eager for glory? As Christian learned the hard way, it doesn't really work if running on Windows is an occasional afterthought in your daily life. [Andy McKay] Mark Hammond and I will take a look at this and see if we can help. Cool! Last I saw, Andreas was planning to release Zope 2.7.7b1 this Sunday (3 July), if you want some practice wink. I'm pretty sure Mark already understands the Zope Windows-installer build process about as well as anyone. If not, I'm happy to help. For someone who runs on Windows routinely, the machinery usually works smoothly. It can be a bear when it doesn't. One predictable problem is that Zope's setup.py gets out of date over time, because people run Zope tests from CVS or SVN checkouts in place, and the repackaging done by setup.py for an installation never gets tested that way. It's broken then for all platforms, but typically whoever builds the WIndows installer is the first to _notice_ it. For a micro release (like 2.7.6 - 2.7.7) a problem there is unlikely. ___ Zope-Dev maillist - Zope-Dev@zope.org 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 )
[Zope-dev] Extending Zope's ZConfig Schema in a Product?
Hello, I've been hitting my head against the wall for a few hours already, so I thought it would be a good time to ask before the house falls apart *wink*. I'm looking back and forth between the Zope and ZConfig sources and documentation to see if I can figure out how to have a Product (or a python package) to extend Zope's ZConfig schema (a.k.a. Zope/Startup/zopeschema.xml) without having to reach into the guts of ZConfig. It looks like the right way to do this would be to extend Zope's schema and then specify a different 'schemafile' to ZopeOptions, but that's not currently possible as Zope doesn't support the '-S schemafile' switch that ZDCtlOptions does. If what I'm looking for seems just stupid please tell me *wink*. All I want to do is to add a simple config 'key' to zope.conf without having to patch the Zope source. Having no other choices, I would go with having my own schema and configfile, but that would be sub-optimal.

Zope/Startup/zopeschema.xml) without having to reach into the guts of ZConfig.

That package than can contain a an XML file that describes your new configuration directives and the code to handle them.

It is too good to be true; sorry. Well, it is true, but it's not what you're looking for. You can't use it to extend the schema for Zope. You can use it to add new concrete implementations for things that are allowed; the original use-case was to allow things like new kinds of storage for the database. I've spent a little time thinking about this issue, and have come up with at least one way to deal with it (and %import would be used, in part), but I've never been completely happy with the approaches. Since using an additional configuration file is possible (and quite easy in Zope 2, since the location of the instance is so easy to discern, I'm not convinced it's actually important to support embedding the configuration for 3rd-party components into zope.conf. If you want something you can use now, using a product-specific configuration file, with an appropriate schema, will do quite well. It also doesn't require hacking (or monkey-patching) Zope or ZConfig, so it would be easy to deploy in a variety of situations. -Fred -- Fred L.

While this may be the most direct answer, on my system there are ~2200 Python source files for Zope+Plone. Most of the objects I've tried to inspect through source code have had multiple parent classes, and some of the parent classes did, too. Consequently it can be a long and tedious undertaking to simply find out which method or attribute name to use, eg: title, Title, getTitle(), get_title(), Title() ... etc. Peter Bengtsson wrote: usually i would simply call dir() or type() on the result object, but those are forbidden in zope. how do you usually solve this?

[Zope] strcoll_nocase gone after moving site?
I have to move a Plone site to another server (from some FreeBSD to a new Trustix), while also switching from Zope 2.7.x5 to 2.7.6, and from Python 2.3.x5 to Python 2.3.5. I have built everything from source, copied 1:1 the Products and Extension directory into a fresh new zope instance, also imported the exported Plone site into it. Was this procedure incorrect? Because till now the result is a disaster; things that worked till now suddenly don't work anymore. Anyway, this is what currently seems to win over me: DocumentTemplate\sequence\SortEx.py line 172: elif f_name in (locale_nocase, strcoll_nocase): func = strcoll_nocase And here global name 'strcoll_nocase' is not defined. I figured this is because in the same file earlier, line 136: import sys if sys.modules.has_key(locale): # only if locale is already imported from locale import strcoll def strcoll_nocase(str1, str2): return strcoll(str1.lower(), str2.lower()) and there the condition of the if is false. If I add import locale before that if, then the error disappears. Any idea what's going on?

I guess I could check each digit of the integer to determine if its ASCII value falls within the appropriate range and if each digit passed this test, then the entire number would be an integer.
