Monkey Patch ZEO server
by Brian Ray Brinegar 24 Sep '02

24 Sep '02

I would like to make a Monkey Patch to the Zeo Server. This will alter the way that Undos are handled in FileStorage. The monkey patch I have doesn't work because the Products are not initialized in the server. Any ideas? -Brian

small patch to cDocumentTemplate.c to ease debugging
by Andreas Kostyrka 23 Sep '02

Hi! As pDocumentTemplate.py is out-of-order at the moment, here is a small patch to make cDocumentTemplate show more attributes (to help debugging).

Searching on '/' with PathIndexes.
by Lennart Regebro 23 Sep '02

23 Sep '02

As far as I can see if you search on '/' on PathIndexes, you don't get any hits at all. (Well, in fact, you get an "index out of range error" but this is a side effect of you not getting any hits). This seems to be because the path index splits the path "/hi/de/ho" into "hi" as level 0, "de" as level 1 and "ho" as level 2. Searching on '/' means that the list of paths to search on is [] and it then fails to find anything. Or in fact, it kinda fails to search... I'm wondering now: Is my analyzing of this problem correct? If it is, then PathIndex would need some kind of special handling for '/' that simply returns everything, right? I feel far to shaky on how PluginIndexes work for me to do that fix without moral support so I would like some feedback here before I start checking in stuff. :-) (Or rather, maybe somebody that already have a Zope sandboxed chacked out could do it?)

Cataloging tool for Zope 3
by Andreas Jung 21 Sep '02

21 Sep '02

I would like to start some work on Zope 3 especially I am interested in having an indexing functionality (comparable to ZCatalog) or porting TextIndexNG to Zope3. In my understanding the ObjectHub framework will be the base for such implementations. Is anyone working on a Catalog service or are there any proposals available? At least I could not found any documents on dev.zope.org except the ObjectHub proposal. Andreas

What builds zlib.so?
by Chris Withers 20 Sep '02

20 Sep '02

Hi, I'm trying to compile and use a checkout of the Zope-2_6-branch. I'm compiling it using: usr/local/bin/python2.1 setup.py build_ext -i ...but when I start Zope I get: 2002-09-19T11:15:31 PANIC(300) z2 Startup exception Traceback (innermost last): Module __main__, line 214, in main Module __main__, line 40, in get_storage Module storages, line 4, in ? Module Globals, line 24, in ? Module TreeDisplay, line 14, in ? Module TreeDisplay.TreeTag, line 23, in ? ImportError: No module named zlib Now, in my 2.5.1 source build, there's a zlib.so in /lib/python. In the 2.6 build, there is not. What builds zlib.so? What needs to be fixed so this works? cheers, Chris

Product construction question
by Joost van Lawick 19 Sep '02

----- Forwarded message from zope-dev-request(a)zope.org ----- Date: Thu, 19 Sep 2002 10:56:07 -0400 Subject: Mailman results for Zope-Dev From: zope-dev-request(a)zope.org To: joost(a)lawick.nl Hi, I have some problems with creating folders and objects. PF is a Folderish class. This is the add function (or manage_add): def addPF(self, id=None, title=None, usercontract=None): """ Create a portfolio """ if not id: id = uuidgen() p = PF(id, title, usercontract) self.Destination()._setObject(id, p) # create an account p.addAccount(id='account', valuta='EUR') p.manage_addFolder(id='KKK') return id Now I have the same type of construction for an Account class which is a SimpleItemish class : def addAccount(self, id=None, title=None, valuta=None): """ Create an user Account """ if not id: id = uuidgen() p = Account(id, title, valuta) 1: #self.Destination()._setObject(id, p) 2: self._setObject(id, p) return id When I comment in line 1 and leave out line 2, I get an Attribute Error on Destination. When line 1 is commented out and 2 goes in: Voila! I can still create Account objects in the ZMI. So what does the Destination() method do in construction of an object? Cheers, Joost -- Joost van Lawick E: joost(a)lawick.com W: http://www.lawick.com/ -- Joost van Lawick E: joost(a)lawick.com W: http://www.lawick.com/

WebDAV Redirects or overriding IDs duing creation
by Johan Carlsson [Torped] 19 Sep '02

19 Sep '02

Hi gurus, I'll try this question on this list as well (a part form zope(a)zope.org) Is it possible to make a redirect during a WebDAV request. For instance I have a PROPFIND one an object that has been renamed and I whan the PROPFIND to access the object with the new ID. I have tried to return a prop result with the information from the renamed object, but the client seems to ignore that (no kidding its MS Web Folder, so what did I expect ;-) Is there a correct way to do this. What I want to do is for the server to override the requested ID on any object or collection that is being created with something more appropriate like the created objects/collections meta_type. MS WebFolders defaults to "New Folder" for collections.

Plone, PageTemplates and Zope2.6
by alan runyan 19 Sep '02

19 Sep '02

using chrism-install-branch and caring much less than I have in my past life - I have run ab against Plone in Zope2.6. It appears that Zope2.6 is significantly slower than Zope2.5.1. I ran ab from my Windows XP machine on a local network. 300Mhz Celeron w/ 256MB RAM Zope2.5.1 Python 2.1.3 ab -n 10 http://mysite/plone 1.30 Requests per second Zope2.6 Python 2.1.3 ab -n 10 http://mysite/plone 0.87 Requests per second I ran the tests a few times and picked the highest number. In both 2.5.1 and 2.6 the "target cache" setting is higher than 4000 (and I am only requesting the first plone page). Also Andy McKay did some quick benchmarks using a simplified PageTemplate skin and he is getting ugly results (he is migrating from DTML to PageTempaltes). cheers, ~runyaga

Testing changes break tests when Products are in INSTANCE_HOME
by Chris Withers 19 Sep '02

19 Sep '02

Hi, The changes made to bring the Testing package into play some while back appear to have broken usage of testrunner.py to run tests if the products you're trying to test are in an INSTANCE_HOME's Products directory. If, for example, I do: set ZOPE_HOME=D:\Zope\2.5.1\ set SOFTWARE_HOME=D:\Zope\2.5.1\lib\python set INSTANCE_HOME=D:\Zope\cmf_dev\ set PYTHONPATH=D:\Zope\2.5.1\;D:\Zope\2.5.1\lib\python set Z_DEBUG_MODE=1 D:\Zope\2.5.1\bin\python D:\Zope\2.5.1\utilities\testrunner.py -d D:\zope\cmf_dev\products\cmfcore\ -v 1 (apologies for wrapping) Then I get a myriad of import errors for things like Products.CMFCore.x.y The reason for this is the that Testing sets it's own INSTANCE_HOME before Zope is imported, so while testrunner.py is still happily finding tests wherever you told it to, the INSTANCE_HOME is pointing to the Testing folder which, of course, is missing all the products. What should we do about this situation? I've tried using PRODUCTS_PATH to get around this, but a few tests still seem to fail when executed under that method :-( cheers, Chris

Re: [Zope-Coders] Proposal: put i18n into 2.6
by James Johnson 19 Sep '02

19 Sep '02

We had to wait this long, why not wait for a bit longer. I just hope it doesn't give some the excuse to drag it on more. That was one of the things I loved about Zope was Release Early/often mantra. Now with the 2.6 dabacle lasting over 3 months. This better not happen again people :-) We already know how some people get uneasy when I project starts to languish for months. It only hurts the opensource movement. Peace, -- James From: "Florent Guillaume" <fg(a)nuxeo.com> >As Jim said, "If we want to get this into 2.6, we need to move quickly." I want it in. It's so amazingly useful, that I want it. 2.6 is moving so slow anyway, that I don't see it as a big problem.
