Test runner: layers, subprocesses, and tear down
by Benji York 13 Jul '08

13 Jul '08

I'm working on making the zope.testing test runner run tests in parallelized subprocesses. The option will likely be spelled -j N, where N is the maximum number of processes. I have it basically working, but have noticed a couple odd corners of the test runner that I'd like to clean up. They may be controversial, so I'll ask about them here first. I'd like to 1) remove the layer tear-down mechanism entirely, and 2) make (almost) all layers run in a subprocess. I want to do #1 because it would simplify the test runner code and no one seems to be using the functionality anyway. It also appears from reading the code that any tests run in a subprocess (and most are) will never exercise the tear-down mechanism anyway. #2 will add some process start-up overhead, but it'll only be one more process than is already started (and any reasonably-sized test corpus already starts several processes for each test run). The one exception is for running with -D or with a pdb.set_trace() embedded in the code under test. For that case we need a switch to say "don't start any subprocesses at all", I suspect that will be spelled -j0. For motivation, some speed comparisons: running a particular test suite with 3876 tests (mostly doctests, and mostly functional) without the patch takes 6 minutes, 42 seconds; my branch runs the same tests in 3 minutes and 22 seconds (give or take) on a dual-core box with 3 simultaneous subprocesses. -- Benji York Senior Software Engineer Zope Corporation

ZCatalog sorting issue
by Martijn Jacobs 12 Jul '08

12 Jul '08

Wat denk je hiervan? Hello. In zope 2.10.5 (and probably 2.10.6 and 2.11 and, as I've read, all releases above 2.7) we've encountered a sorting bug in a dtml-in call when querying the catalog. I don't think it's dtml only related, but I'm not sure about that. It is the same bug as found on : https://bugs.launchpad.net/zope2/+bug/143504 Adding def __cmp__(self, other): return 0 to Products.ZCatalog.CatalogBrains.AbstractCatalogBrain seems to correct the problem though and I was wondering why this isn't added in the zope core. Does it break other stuff or should the problem fixed somewhere else? Somebody has some thoughts?

Proposal: add form support to zope.session.http.CookieClientIdManager
by Jim Fulton 10 Jul '08

10 Jul '08

As it's name implies, the CookieClientIdManager manages HTTP client ids using HTTP cookies. Recently, I've found it to be useful to be able to get a client id via form data. The reason is that flash programs don't send browser cookies. This bit me when trying to use the YUI uploader, http://developer.yahoo.com/yui/uploader/, which uses a flash program to select and upload files. I'm using session authentication and the only way I found to make it possible to upload files to protected pages was to pass the client id as form data. I have a custom client id manager that gets the id from form data as well as from a cookie. I propose to merge this with CookieClientIdManager. Any objections? Jim -- Jim Fulton Zope Corporation

PAULA: bringing Zope 3's authentication to Plone and beyond
by Florian Friesdorf 10 Jul '08

10 Jul '08

Hi *, within the scope of google summer of code I am integrating zope 3's PAU with Plone's PAS and further enable (non-AT) content objects as source for users and groups. All functionality is developed in pure zope3, the plone integration is happening in a separate packages. All documents describing the project, as well as links to the code can be found here: https://chaoflow.net/projects/gsoc2008/z3membrane-ldap The code is not very interesting right now, but now would be the time to take any influence on what will be created during the next month - I am planning to continue to work on the project after the SoC. I will keep you updated on major advancements of the code. regards florian

Zope3 installation on windows - how?
by Hermann Himmelbauer 10 Jul '08

10 Jul '08

Hi, I currently try to install Zope3-4.0c1 on a windows machine, without any success for now. What I need is an installation that includes basically all packages that are in the tarball into the python path. I tried the following: 1) Tarball: Here, install.py fails due to some compiler problems - it suggests to specify "-c mingw32", however, when I do so, install.py complains that it does not know this "-c mingw32" option. Something like "python install.py build_ext -cmingw32" works, it seems that all needed packages are correctly compiled. When I try a "python install.py install" afterwards, it once again complains that it needs mingw32. So I'm stuck. 2) I tried installing it via the descriptions given here: http://wiki.zope.org/zope3/Zope340c1 $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.5.1 formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -v This gives me some buildout error. 3) Next I tried the information from here: http://wiki.zope.org/zope3/MakingARelease svn co svn+ssh://svn.zope.org/repos/main/zope.release/branches/3.4 release-3.4 $ cd release-3.4 $ py24 bootstrap.py $ ./bin/buildout -N And there's once again this mingw32 problem. 4) Next, I tried zopeproject: $ easy_install zopeproject $ zopeproject HelloWorld First, zopeproject does not install the packages into the Python site-packages, moreover, there's once again the "mingw32" problem which I'm unable to solve. What can I do? Is there perhaps some precompiled Windows distribution for Zope-3.4 available? Or is there some trick to make things work with mingw32?

zope.testing releases on PyPI
by Andreas Jung 10 Jul '08

10 Jul '08

Hi, the zope.testing releases on PyPI are apparently a bit weird. - zope.testing 3.5.1 has been the latest released version on PyPI last week - I created V 3.5.2 on Sunday. Phillip granted me access to the zope.testing package on PyPI in order to upload 3.5.2 (which worked) - I created V 3.5.3 yesterday morning. Uploading the egg was impossible because I had no longer rights (in fact permissions are currentl only granted to Jim and Fred Drake (not even Phillip) - search for "zope.testing" on PyPI leads me to version 3.0 instead of 3.5.1 Does anyone know what happened here?

zope.app.authentication broken!
by Roger Ineichen 10 Jul '08

10 Jul '08

hi I'm pretty sure the container changes are not compatible because of some bad __init__ methods in inherited classes in other packages. But that's not the fault of the refactoring that is correct as far as I can see. zope.app.authentication.groupfolder.py class GroupFolder(BTreeContainer): .... def __init__(self, prefix=u''): self.prefix=prefix super(BTreeContainer,self).__init__() ^^^^^^^^^^^^^^^^^^^^ The *super(BTreeContainer,self).__init__()* will not initialize the right thing here. right? What was the reason of calling: super(BTreeContainer,self).__init__() instead of: super(GroupFolder, self).__init__() btw, did someone run the tests with all packages that depend on zope.app.container?
