Manuel Beta
by Benji York 14 Jan '11

14 Jan '11

I've just released the first beta of Manuel, my next-generation doctest project. Being that zope-dev has some of the most well-informed users of doctest (and some of the most well-informed non-users of doctest), I'd like to gather feedback from this group before making an announcement to the wider world. Manuel is available from PyPI (http://pypi.python.org/pypi/manuel) with docs, details, and examples at http://packages.python.org/manuel/. I'm interested in any feedback and/or questions you may have be it technical, documentation, or "marketing" (i.e., how do I describe what Manuel does and what benefits it has). -- Benji York Senior Software Engineer Zope Corporation

zope.testing: Define __add__ for RENormalizing
by Christian Zagrodnick 06 Dec '09

06 Dec '09

Hi, I suggest defining __add__ for zope.testing.renormalizing.RENormalizing which would return a new Checker with the transformers combined. This allow better reuse of those checkers without having to define the patterns separately. Like checker = checker_a + checker_b.

zc.relationship - can't pickle module objects
by Martin Aspeli 09 Nov '09

09 Nov '09

Hi, I *think* this is a bug in zc.relationship, but I'm not quite sure. I'm using ZODB3 3.8.1 (to get BLOB support) and trying to install plone.app.relations, which depends on zc.relationship 1.0.2. In particular, it subclasses zc.relationship.shared.Container, and stores a zc.relationship.index.Index object in self.relationIndex. Now, the __init__ of zc.relationship.index.Index, which derives from Persistent, contains the code below. In self._relTools and and self._attrs, there are a pile of modules, types and functions being stored. I think these are causing the ZODB to barf. Interestingly, with whatever version of ZODB that comes with Zope 2.10 (3.7?), there's no problem. Any ideas how to work around this, or even why it's a problem in one version of the ZODB but not another? zc.relationship.index.Index's initialiser: def __init__(self, attrs, defaultTransitiveQueriesFactory=None, dumpRel=generateToken, loadRel=resolveToken, relFamily=IFBTree, deactivateSets=False): self._name_TO_mapping = OOBTree.OOBTree() # held mappings are objtoken to (relcount, relset) self._EMPTY_name_TO_relcount_relset = OOBTree.OOBTree() self._reltoken_name_TO_objtokenset = OOBTree.OOBTree() self.defaultTransitiveQueriesFactory = defaultTransitiveQueriesFactory self._relTools = getModuleTools(relFamily) self._relTools['load'] = loadRel self._relTools['dump'] = dumpRel self._relLength = Length.Length() self._relTokens = self._relTools['TreeSet']() self.deactivateSets = deactivateSets self._attrs = _attrs = {} # this is private, and it's not expected to # mutate after this initial setting. seen = set() for data in attrs: # see README.txt for description of attrs. if zope.interface.interfaces.IElement.providedBy(data): data = {'element': data} res = getModuleTools(data.get('btree', IFBTree)) res['element'] = val = data['element'] res['attrname'] = val.__name__ res['name'] = data.get('name', res['attrname']) if res['name'] in _attrs or val in seen: raise ValueError('Duplicate in attrs', name, val) seen.add(val) _attrs[res['name']] = res res['dump'] = data.get('dump', generateToken) res['load'] = data.get('load', resolveToken) if (res['dump'] is None) ^ (res['load'] is None): raise ValueError( "either both of 'dump' and 'load' must be None, or neither") # when both load and dump are None, this is a small # optimization that can be a large optimization if the returned # value is one of the main four options of the selected btree # family (BTree, TreeSet, Set, Bucket). res['interface'] = val.interface res['multiple'] = data.get('multiple', False) res['call'] = zope.interface.interfaces.IMethod.providedBy(val) if res['TreeSet'].__name__.startswith('I'): Mapping = IOBTree.IOBTree else: assert res['TreeSet'].__name__.startswith('O') Mapping = OOBTree.OOBTree self._name_TO_mapping[res['name']] = Mapping() # these are objtoken to (relcount, relset) Regards, Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.

How to test changes to ZTK packages?
by Jim Fulton 07 Jul '09

07 Jul '09

I should know this, but I don't. What is the recommended way to test changes to core ZTK packages to mitigate the risk that changes affect other packages? Is there a page somewhere with instructions? I tried using using zope.release. Building the trunk of zope.release with Python 2.4 and running the tests gives lots of test import errors and test failures. (Lots of tests want to import z3c.pt.) The tests hang when I try to build and run with Python 2.6. BTW, zope.release wants lxml, which is a real pain on Mac OS X and Centos 4. Does the ZTK really need to depend on lxml?

Making PersistentList satisfy zope.schema.List
by Paul Carduner 01 Jul '09

01 Jul '09

I noticed that PersistentList and PersistentDict do not satisfy zope.schema.List or zope.schema.Dict, which is rather annoying. For example: class IBlogPost(Interface): tags = zope.schema.List(title=u'Tags', value_type=zope.schema.TextLine) class BlogPost(Persistent): implements(IBlogPost) tags = FieldProperty(IBlogPost['tags']) def __init__(self): super(BlogPost, self).__init__() self.tags = persistent.list.PersistentList() #aaah, WrongType error... will throw a WrongType: ([], <type 'list'>) error, which is especially confusing because the repr for PersistentList makes it look an awful lot like a regular list. same thing happens with PersistentDict. I would like to modify zope.schema._bootstrapfields by changing the _type attribute of the List class to (list, UserList), and do the same for Dict with (dict, UserDict). Then anything inheriting from UserList (including PersistentList) will satisfy the schema. Can anyone think of a reason why this would be bad? -- Paul Carduner http://www.carduner.net

ZCatalog and indexes cleanup
by yuppie 29 Jun '09

29 Jun '09

Hi! I did plan to work on a small catalog improvement, but after looking at the code I'd like to do some cleanup first: 1.) remove the deprecated TextIndex The deprecation warning says: 'Using TextIndex is deprecated (will be removed in Zope ' '2.12). Use ZCTextIndex instead.' 2.) remove CHANGES.txt, README.txt and version.txt from Products/ZCatalog These files seem to be obsolete. 3.) remove security declarations from ZCTextIndex and DateRangeIndex All the other indexes don't have security declarations. AFAICS there is no way to access indexes from untrusted code without having the 'Manage ZCatalogIndex Entries' permission. 4.) add 'indexSize' to IPluggableIndex and implement it where missing ZCatalog uses that method and most indexes implement it already. If there are no objections, I'll make these changes on the 2.12 branch and the trunk. Cheers, Yuppie

Schema to JSON
by Paul Wilson 29 Jun '09

29 Jun '09

Hi, I'm about to embark on a module to serialize Zope schemas into the JSON format for my application, taking inspiration from z3c.schema2xml. I've had a look around SVN to see if this functionality has already been implemented but can't find anything - does anybody know whether this has already been done somewhere? Also, it makes sense in my mind for a schema2xml and schema2json to implement the same interface. How does Zope handle this case? With a format agnostic interface module or something? Many thanks, Paul
