BTrees and ConflictErrors.
by Anthony Baxter 30 Jul '01

30 Jul '01

I thought the newer BTrees code was meant to deal with conflicts from two entries being added at the same time? I'm using CoreSessionTracking 0.8 with an external data source on a bsddb3Storage.Minimal storage mounted via ZEO (using the current Zope2.3 code). If two sessions are created around the same time, I'm seeing ConflictErrors - there doesn't seem to be any attempt to invoke the resolveConflict code. Any ideas what I'm missing here? Anthony

No I need to combine the data at search time. This is due to the fact that the meta_data is user specific. Every user will have their own set of data for most items in the catalog. I want to join an arbitrary query of the catalog with the user specific data to have a search with personalized information. My problem is that under normal circumstances python objects can be extended by adding attributes to them. Why can't I do that under zope? or why isn't the results of a catalog search a list of dictionarys rather than a list of objects?

Can't get tests in Products folder to run
by Chris Withers 29 Jul '01

29 Jul '01

Hi, More testing stuff :-S I can't get any of the tests in the Products folder to run. I must be doing something wrong but I can't figure it out. The command line I'm using is: E:\Zope\2.4.0>bin\python utilities\testrunner.py -d lib\python\Products\ ...and it's finding tests for ZCatalog, PythonScripts, PageTemplates, PluginIndexes and CoreSessionTracking; but they're all failing with import errors and not a single test runs. What am I doign wrong here? cheers, Chris PS: oops, I should expect PageTemplates to fail since my pristine 2.4.0 install doesn't have the necessary python packages.

ZCatalog: Updating pre-2.4 indexes to PluginIndexes
by Steve Alexander 28 Jul '01

28 Jul '01

I have a site with a number of ZCatalogs that have a whole load of pre-2.4 indexes. I want to upgrade them all to new PluginIndexes. I'd hoped there would be an upgrade button in the ZCatalog ZMI, or that they would get upgraded automatically when I reindex the catalog. Sadly not. Has anyone written an external method (or something) for this? Cheers. -- Steve Alexander Software Engineer Cat-Box limited

The point of unit tests...
by Chris Withers 28 Jul '01

28 Jul '01

...is to run them all before you do a release, surely? Try this in a fresh 2.4.0 final install on windows: E:\Zope\2.4.0>bin\python utilities\testrunner.py -a ...which will run all the unit tests in the Zope install. The results are not good :-( Well, I'm gonna see how many failures I can fix and stick them all in the collector. Watch this space... cheers, Chris

WebDAV--What am I missing?
by Alex Kelly 27 Jul '01

27 Jul '01

I am trying to get WebDAV access working with our Zope installation. I have looked through the zope.org docs, and have seen some discussion about it in the list archives, but have not found any answers to anything I am looking for. I am running Zope 2.3.3 with ZEO 1.0b3. I have DAV access running on port 9800 (since that is the official port) and I am able to connect to it. I have used both DreamWeaver 4 on Windows and cadaver on Linux to access the server, both with similar results. Most of the testing I have done has been with cadaver. I can edit items with both programs, however...The DAV server is giving me the HTML output, not the DTML I am expecting. Cadaver constantly complains that the folders are "not a valid collection", and if I don't specify the -t (tolerant) option, it won't let me descend directories/folders. DreamWeaver seems perfectly happy getting all the content (apart from it complaining that it has no extension...but I understand that). Basically my questions are: 1. What do I have to do to get it to give me the DTML code, and not the HTML output? 2. Is there a permission somwhere to control DAV access (as far as anonymous reads)? 3. Are there any other DAV controls that I am missing? 4. What else am I probably doing wrong in relation to this :) Thanks, Alex Kelly
