ANN: TextIndexNG-2.04 released (IMPORTANT for 2.03 users)
by Andreas Jung 07 Dec '03

07 Dec '03

I have just released TextIndexNG 2.04 which fixes a critical problem in the ranking code which came up with some changes introduced in V 2.03 which has been released last week). V 2.03 user should upgrade to 2.04 as soon as possible. V 2.02 users are not affected but should upgrade to V 2.04 if possible to benefit from the changes in the reindexing code.

When the param is a record, around line 95, I've added: if keys == ['']: keys = None Is it correct? Seems to work with all indexes I've and KeywordIndexes, which works also with AND as operator. ________________________________________________ Message sent using ALFANET Caorle WEBMAIL 1.0

[Ann] ZopeProfiler 1.1: learn what Zope is using its time on
by Dieter Maurer 07 Dec '03

07 Dec '03

ZopeProfiler allows you to determine what Zope spends its time on. This provides valuable insight (especially when you feel your site is a bit slow) and suggests optimizations. ZopeProfiler 1.1 comes with a slightly improved user interface and was made Zope 2.8 compatible (which currently lives only in CVS).

A question on how external methods reference modules
by Goldthwaite, Joe 06 Dec '03

06 Dec '03

I basically created two modules. In module1.py I have my stub function that chains to module2.py. module1.py import module2 def ReturnData(): """Return some test data""" return module2.GetTheData() module2.py def GetTheData(): """Return the actual data""" return """the actual data""" I can run this in python and an error that 'module2' wasn't found so I had to append it's path using the sys.path.append function. Now I'm not getting an error so I think it's finding module2 but it doesn't seem to be finding the function. I'm confused. Can anyone explain what's going on? As a second part of the question, will this allow me to modify the external modules without re-loading them into Zope?

RE: [Zope] Probably too much to hope for but...
by Goldthwaite, Joe 06 Dec '03

Thanks Jim, That's what I was looking for. I had already gotten it to work from Python but that was causing me to mix my business login with the presentation logic which is supposed to be a no no. I'm seriously about putting everything into external python modules and just returning HTML. I think that may make it easier for some things. It looks like Zope has a lot more number and time formatting functions than Python so I'm still undecided. Thanks. It helps a lot.

So, you can make a Script (python) that looks something like: script name: nearest_dollar_thousands_commas_negative_parens param : aVal #round-off, do thousands_commas and put parens around it if negative from Products.PythonScripts.standard import thousands_commas zero = 0.0 if not same_type(aVal,zero): aVal = float(aVal) rounded = '%0.0f' % aVal isNegative = aVal < zero and not float(rounded) == zero v = thousands_commas(rounded).replace('-','') if isNegative: v = '(%s)' % (v) return v Then call it: <p tal:content= "python:context.nearest_dollar_thousands_commas_negative_parens(item.YTDCurrent) -- Jim Washington Property of Bar-S Foods.

why a xcatalog keywordindex is mandatory?
by Yurj 06 Dec '03

06 Dec '03

I've this in the form input of a zcatalog query: <tr><td>Collocazione AND</td> <td><textarea name="COLL2.query:lines:record" rows="3" cols="40"></textarea> <input type="hidden" name="COLL2.operator:record" value="and"> </td></tr> where COLL is a keywordindex. All works if I put something in the textarea. But if it is empty, it finds nothing instead of all, as other records. Help :) I've tried to change, in the form, COLL with COLL2 and do in the report script: <dtml-call "REQUEST.set('COLL',_['COLL2'])"> but it gives error (Error Type: TypeError Error Value: object has read-only attributes) ________________________________________________ Message sent using ALFANET Caorle WEBMAIL 1.0

problems with tests in Zope/CMF
by Pascal Poizat 06 Dec '03

06 Dec '03

Hello I am trying to write a document on building a Plone site for research labs (a step-by-step doc). Having done some experiments with old versions of Plone or Zope, I realized that some products were difficult to install (due to lots of dependencies ...) with an old python such as the one in Zope 2.6.2. Well, I decided to get all last versions : zope 2.7b3 (source) CMF 1.4.2 (tarball, I already had it) Plone 2.0 RC2 (tarball, I already had it) and ... Python 2.3.2 (source) First of all, please note that I use now (it was different with zope 2.6.2 which had its own python + libs) my "system" python. By the way, I wonder if this is a problem ... Well let's now come to my REAL problem : tests. 1 - PYTHON Well, I first installed python 2.3.2 from sources and then did some tests : cd /usr/lib/python2.3/test python testall.py -> everything is ok (but for some tests which seem to "normally" fail under "Linux2" whatever it is and the NIS one). Nice ... I now have a 2.3.2 python with working Tk modules and so on (the last python I had installed from scratch, the 2.2.2 had some problems due to my install process) 2 - ZOPE I install it "locally" : ./configure make instance Which installs Zope in its own source directory. Moreover it seems to use the "system" python by default (ie /usr/local/bin/python + /usr/local/lib/python2.3 directory). Then I go for some tests ... export ZOPE=$HOME/Zope <- the install directory cd $ZOPE python test.py (very, 2219 tests, all is ok, 2/3 warnings) but THEN it gets more complicated : bin/testrunner.py -a -q -d $ZOPE/lib/python and then ... VERY LONG, 2508 tests, 12 errors !! (all in zLOG by the way), some warnings Well I was quite puzzled then but ... well the ZMI seemed to work so ... let's go for CMF ! 3 - CMF With comparison with python and Zope, a very newbie-friendly install process : mv CMF-1.4.2/CMF* $ZOPE/lib/python/Products mv CMF-1.4.2/DCWorkflow $ZOPE/lib/python/Products All seem ok under the ZMI but ... I decide to go for some tests to be sure (I must be a masochist person ;)) ) cd $ZOPE bin/testrunner.py -a -q -d $ZOPE/lib/python/Products ... ... ... (yes : VERY VERY long) -> result ? 5833 tests (ok there is the CMF installed now) but : 225 errors + 3 failures !! (and lots of deprecation warnings) 4 - and Next ? I've installed Plone 2.0RC. It works. But ... all these failing tests make me ask myself if someday ... the hidden bug will appear ! :)) Did I miss something in my way of testing ?

Zope on FreeBSD/sparc64
by Michael Piotrowski 06 Dec '03

06 Dec '03

Hi, I've been trying to get Zope to run on a Sun Blade 100 running FreeBSD 5.1, but it segfaults and dumps core on startup regardless of the version of Python and Zope. This applies to both Zope 2.7b3 with Python 2.3 as well as the binary packages of Zope 2.6.1 with Python 2.2.2 from the FreeBSD ports collection. We're using Zope without problems on FreeBSD/i386, but is *anybody* using it successfully on FreeBSD/sparc64?
