Finding specific parent object with acquisition ?
by Martijn Jacobs 17 Aug '01

17 Aug '01

Hello! I have a question about acquisition and namespaces and how to use them in your product code..... Imagine you have the following structure in zope : (ProductA is a Product derived from Folder/Objectmanager so it can hold other objects, ProductB is a simpleitem product) Root | ----ProductA | ----Folder6 | ----Folder7 | ----ProductB | ----DTMLDoc1 OK : If I execute http://localhost/ProductA/Folder6/Folder7/DTMLDoc1 and I put in the DTMLDoc1 this code : '<dtml-var "ProductA">' , it will look back and it will find the ProductA instance and it will call it's index_html, because in DTML you have a namespace where the DTML-execute code can find 'ProductA' on a great way. Now the following thing : I want to acquire a reference TO ProductA IN the product code of ProductB so I will be able to execute functions from ProductA in ProductB, for example : class ProductB(.....) def blah(): refProdA = self.acquire('ProductA'); (self.acquire is not a real function, only for illustration what kind of function I would like to have in a Zope object :) Do I have a same namespace in my Productcode (the python code of this product) so it will acquire automaticily the reference to ProductA, for example the way I use here above? Or do I have to program this manually by repeatly calling the aq_parent method until I find an instance of 'ProductA' ? thnx in advance, martijn jacobs eastsite

RE: [Zope-dev] MySQL with Zope 2.4 & Python 2.1
by Juan Javier Carrera Obrero 17 Aug '01

17 Aug '01

I am sorry, but I do not understand your previous request. I comment you it again. I am using Zope 2.4.0 and Python 2.1 in Win32 plataform. Firstly, I have installed ZMySQLDA-1.1.3 as it is showing in http://www.zope.org/Members/philh/mysql . However, the next error is showed: "ImportError: DLL load failed: No se puede hallar uno de los archivos de biblioteca necesarios para ejecutar esta aplicación". It is produced because the MySQL.pyd library was compiled with Python 1.5. I have trying recompile the source with Microsoft Visual C++ 5.0 for obtaining the MySQL.pyd library with python 2.1, but it generates compilation errors as: "MySQLmodule.c(1147) : error C2102: '&' requires l-value in the line: tf = &(mysql_fetch_field_direct(self->res,j));", and link errors as: "c:\python21\libs\python21.lib : fatal error LNK1106: invalid file or disk full: cannot seek to 0x3adc9977. Error executing link.exe." Then, I have trying it with ZMySQLDA-2.0.7 and MySQL-python-0.9.0 (for I obtain MySQLdb). as it is showing in http://zope.org/Members/philh/ZMySQLDA_html . However, when I try to execute "python setup.py build" for obtaining "_mysql.pyd" with Python 2.1, it generates a "Critical Link Error", although I do not understand why?, because I have installed in my computer: MySQL database 3.23.40, Python 2.1 (with Win32 extensions) and Microsoft Visual C++. Could you help me about this problem?, or Could you send me the "_mysql.pyd" library compiled for Python 2.1 or "MySQL.pyd" for Python 2.1 ? Thank you very much.

This > doesn't crash Zope, but brings down the FCGI and PCGI Servers. Ah, yes. that would do it... there are some oher changes needed to this function. I suggest you get the last version from the Zope CVS; revision 1.13 was the last one before it was deleted (or I can sent you it by email...)

Roll Your Own vs GUF vs exUserFolder - Why is one better than the other
by Dario Lopez-Kästen 17 Aug '01

17 Aug '01

Hello! I would like to hear from people using GUF and/or exUserFolder and what they think of them, especially why they prefer on over the other, or opinions on why one is better than the other. I've been trying to understand how both products work and AFAICT the main difference is that exUserFolder provides user properties while GUF does not. GUF seems to be better at handling roles thn exUserFolder (in terms of being able to extract them from the database). Any comments insight, corrections of misconceptions are welcome. I need to have a working solution to our problem RSN and I want to use as much of Zope as possible. It won't be possible to solely rely on the zope sec mechanisms but if i can delegate to zope as much as possible it would be a big gain. The last and least desireable option would be to simply ignore the zope sec mechanisms and roll our own sec management. Thank you, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario(a)ita.chalmers.se ICQ will yield no hits IT Systems & Services

BugFix to enable other products to register Splitters
by Chris Withers 16 Aug '01

16 Aug '01

Hi, Given the Collector is broken again, here's a mail report of a bug and fix: The way splitters are currently implemented in PluginIndexes makes it practically impossible to register new types of splitter. These patches provide a registerSplitter method for the PluginIndexes.TextIndex.Splitter module. All the tests pass and the registerSplitter function is implicitly tested by this ;-) cheers, Chris & Harry --- e:\refcvs\zope\lib\python\products\pluginindexes\textindex\splitter\__init__.py Fri Jun 01 14:47:34 2001 +++ E:\localcvs\AlexCons\Products\PluginIndexes\TextIndex\Splitter\__init__.py Thu Aug 16 11:43:39 2001 @@ -1,22 +1,32 @@ -import os,sys,exceptions +from ZopeSplitter import Splitter as ZopeSplitter +from ISO_8859_1_Splitter import Splitter as ISO_8859_1_Splitter -availableSplitters = ( - ("ZopeSplitter" , "Zope Default Splitter"), - ("ISO_8859_1_Splitter" , "Werner Strobles ISO-8859-1 Splitter") -) +splitterNames = [] +splitterMapping = {} -splitterNames = map(lambda x: x[0],availableSplitters) +def availableSplitters(): + list = [] + for name in splitterMapping.keys(): + list.append((name,splitterMapping[name][0])) + return tuple(list) def getSplitter(name=None): - if not name in splitterNames and name: - raise exceptions.RuntimeError, "No such splitter '%s'" % name - - if not name: name = splitterNames[0] - if not vars().has_key(name): - exec( "from %s import Splitter as %s" % (name,name)) - - return vars()[name] + if name is None: + name = splitterNames[0] + + try: + return splitterMapping[name][1] + except KeyError: + raise RuntimeError, "No such splitter '%s'" % name +def registerSplitter(name,description,module,default=0): + global splitterNames + splitterMapping[name]=(description,module) + if default: + splitterNames.insert(0,name) + else: + splitterNames.append(name) - +registerSplitter("ZopeSplitter", "Zope Default Splitter", ZopeSplitter) +registerSplitter("ISO_8859_1_Splitter","Werner Strobles ISO-8859-1 Splitter", ISO_8859_1_Splitter) --- e:\refcvs\zope\lib\python\products\pluginindexes\textindex\tests\testSplitter.py Mon Aug 06 20:23:04 2001 +++ E:\localcvs\AlexCons\Products\PluginIndexes\TextIndex\tests\testSplitter.py Thu Aug 16 11:49:56 2001 @@ -119,9 +119,9 @@ def testAvailableSplitters( self ): "Test available splitters" - assert len(Splitter.availableSplitters) >0 + assert len(Splitter.availableSplitters()) >0 assert len(Splitter.splitterNames)>0 - assert len(Splitter.availableSplitters)==len(Splitter.splitterNames) + assert len(Splitter.availableSplitters())==len(Splitter.splitterNames) @@ -133,21 +133,11 @@ assert result==splitted, "%s: %s vs %s" % (sp_name,result,splitted) - def testZopeSplitter(self): - """test ZopeSplitter (this test is known to fail because it does not support ISO stuff) """ - - for text,splitted in self.testdata: - self._test("ZopeSplitter",text,splitted) - def testISOSplitter(self): """test ISOSplitter""" for text,splitted in self.testdata: self._test("ISO_8859_1_Splitter",text,splitted) - -# for loc in ["","ru_RU.KOI8-R"]: -# locale.setlocale(locale.LC_ALL , loc) - def test_suite():
