Testing my product
by Adrian Hungate 18 Jan '02

18 Jan '02

I have had a lot of interest in a couple of my products, and I would like to ensure they are as stable as I can make them. I have heard a lot on here about unit-testing, is there a guide to creating unit-tests? Is there a procedure, or something to follow so that I can be sure I am testing "the right things"? Any help would be greatly appreciated. Adrian... -- Adrian Hungate All views expressed in this email are those of the whole world, however some people don't realise this yet.

unrestrictedTraverse and URLs ending in slash.
by Lennart Regebro 17 Jan '02

17 Jan '02

I quite often use URLs that end in a slash (in fact, I prefer it that way, since I then can add methods easily without having to care about if the url is the root '/' or another object). This got me into trouble, though, since unrestrictedtraverse can't handle URLs that end in a slash. I have patched it in my 2.3.4 installation so that it does, and think it would be a good idea to include this fix in Zope. What do you others think? >> OFS.Traversable Line 68: unrestrictedTraverse__roles__=() # Private def unrestrictedTraverse(self, path, default=_marker, restricted=0): if not path: return self get=getattr has=hasattr N=None M=_marker if type(path) is StringType: if (path[-1] == '/') and (path != '/'): path = path [:-1] # Handle URL's that end in a slash. path = split(path,'/') else: path=list(path)

Upgrading to python 2.1.2 and Zope 2.5b4
by Tony McDonald 17 Jan '02

17 Jan '02

Hi all, I want to upgrade to python 2.1.2 (from an existing 2.1 installation) and at the same time upgrade to 2.5b4 in the hopes that this combination will fix the threading problem under Solaris. Q1: Is this the right combination to use, I've read that I should use 2.1.2 and 2.4.4 (possible numbering scheme). If so, I can wait (but we are getting core dumps regularly now) Q2: (and apologies, as this is a more python-orientated question) Can I just do a 'make install' of python 2.1.2 and be sure that it's not going to make my MySQL and other modules in site-packages unusable? (sorry if this is a daft question - I have a *lot* of zope sites using python 2.1 at the moment) Many thanks Tone -- Dr Tony McDonald, Assistant Director, FMCC, http://www.fmcc.org.uk/ The Medical School, Newcastle University Tel: +44 191 243 6140 A Zope list for UK HE/FE http://www.fmcc.org.uk/mailman/listinfo/zope

Re: [Zope-dev] Accessing objects starting with _
by Gary & Karyn 17 Jan '02

17 Jan '02

In a similar vein to Dieter's answer, depending on the rest of your situation you might also want to look at my VirtualHostFolder, now in beta at http://www.zope.org/Members/poster/VHF . If virtual hosts are any part of your set up, and you are willing to try a beta, I might be interested in creating a new HostOverride implementation for your need, in order to show the flexibility of my product and also to test my interface design. I would then not feel bad if you didn't end up using it, but would appreciate the chance to try my design out with a real need. So get back to me if this is of any interest to you (if you are not using virtual hosts then there is probably no reason for me to kick in here: the SiteAccess tool will do the job more efficiently, I would guess). Gary P.S. If you look at the product as released... Since this last beta release I am still tweaking interfaces for future design flexibility and current efficiency, as well as decoupling some of my own implementations to follow my interfaces better. I also now have a hard redirect (I mean a browser redirect) IHostOverride object that can be a part of a host object the same way an Alias can. The Alias object is not what you want, by the way: the design of that object is to alias folders only (because it does some path hacking tricks that are only pertinent to folders). I would have to build you another IHostOverride implementation, either (ideally) as some kind of generic stack rewriter modifiable through the web or (if that UI proves too problematic) as a rewriter specific to your FrontPage needs. Writing the redirect sub-object was pleasantly easy, an hour or less of work, so I make this offer in the expectation that it would be a quick diversion to add some new flexibility to my product. g

allow_module broken in Zope 2.5?
by Casey Duncan 16 Jan '02

16 Jan '02

I am working on a patch for Formulator so that its exception classes can be imported into a Python Script. the following code works for Zope 2.3 and 2.4 but I get an unauthorized error when I try to import from this in 2.4 (Just tested b4, but not CVS). Here is the code from the module Errors.py in the Formulator product package dir: ---- """Exception Classes for Formulator""" # These classes are placed here so that they can be imported into TTW Python # scripts. To do so, add the following line to your Py script: # from Products.Formulator.Errors import ValidationError, FormValidationError from Products.PythonScripts.Utility import allow_module, allow_class allow_module('Products.Formulator.Errors') class FormValidationError(Exception): def __init__(self, errors, result): Exception.__init__(self,"Form Validation Error") self.errors = errors self.result = result allow_class(FormValidationError) class ValidationError(Exception): def __init__(self, error_key, field): Exception.__init__(self, error_key) self.error_key = error_key self.field_id = field.id self.field = field self.error_text = field.get_error_message(error_key) allow_class(ValidationError) ---- If you create a python script containing: from Products.Formulator.Errors import ValidationError, FormValidationError You get an Unauthorized exception in 2.5, but not in 2.4 or 2.3. I realize this should probably go in the collector, but I wanted to make sure I wasn't doing something dumb first.
