Zope 2.12.0 released
by Andreas Jung 05 Oct '09

05 Oct '09

On behalf of the Zope 2 developers community I am pleased to announce the official release of Zope 2.12.0. Major changes: - Ships with ZODB 3.9 - Runs on top of Python 2.5 and 2.6 (no official support for Python 2.4, your mileage may vary) - Fully eggified - you install Zope 2.12 directly from PyPI using *easy_install* or *zc.buildout* - Lots of cleanup on the module level (e.g. ZClasses have gone forever - like it or not) - Ships with the Zope component library (aka Zope 3.4) - RESTified documentation in order to generate nice looking HTML/PDF documents using Sphinx - lots of other small details For more details, check: http://docs.zope.org/zope2/releases/2.12/WHATSNEW.html Release notes: http://docs.zope.org/zope2/releases/2.12/CHANGES.html Especially read the installation instructions since the installation process is different from all other Zope versions (because of the eggification process). Keep in mind that we do no longer provide the traditional all-in-one source tarball: http://docs.zope.org/zope2/releases/2.12/INSTALL.html The official Zope 2.12 project page on PyPI can be found here: http://pypi.python.org/pypi/Zope2/ If you have found a bug, please report it on Launchpad: https://bugs.launchpad.net/zope2/ I would like to thank all people having contributed to this release. Special thanks to Tres Seaver for his tireless efforts in fixing bugs and maintaining the Zope 2 codebase and Hanno Schlichting who worked hard and steadfast on the eggification of Zope 2 and on the cleanup of various dark corners of the Zope 2 codebase. In addition we launched the dedicated zope2.zope.org microsite today. This is one of the first steps for relaunching the Zope sites (including www.zope.org) asap.

I have some code for building the KGS on download.zope.org for a given release tag. We might extend the code for checking the availablity of the windows eggs for the supported Python versions...any taker? Andreas

Zope 2, WebDAV and browser-default
by Martin Aspeli 05 Oct '09

05 Oct '09

Hi, I came across this trying to implement WebDAV support for some content in Zope 2. The ZPublisher will always traverse to the return value from 'browserDefault()' (either from a custom IBrowserPublisher adapter, or the DefaultPublishTraverse object hardcoded in ZPublisher.BaseRequest) when it gets to the end of a traversal chain, even for WebDAV requests. This makes it impossible to e.g. get a folder listing in WebDAV. The default 'browserDefault()' will call __browser_default__() on the context if that exists. If not, it will call queryDefaultView(), which returns a view name as set by a <browser:defaultView /> directive, and return that name unless it is None. The publisher will then traverse to the name indicated. This breaks WebDAV in two ways: Consider a folder /foo/bar. The class for 'bar' does not implement __browser_default__(), but there is a default view, set with the <browser:defaultView /> directive, called 'index'. Let's say the WebDAV client attempts to do a PROPFIND request to list the folder's contents. The publisher will traverse to /foo/bar and then look up the default view, @@index, and attempt to traverse to that. This doesn't have the PROPFIND() verb method, obviously, since views don't derive from webdav.Resource, and so the WebDAV requests fails. Even if it does, there's some code at the end of BaseRequest.traverse() which checks that the last item in the traversal chain is *not* acquired (i.e. it's a genuine child of the aq_base'd second-to-last item). This is to allow PUT'ing to a name that could've been acquired (via the NullResource mechanism). This means that if you have registered a <browser:defaultView /> for an object, it is impossible for that object to participate in WebDAV requests. We never noticed in Plone before, because most Plone content implements __browser_default__ so that it delegates to PloneTool.browserDefault() which aborts immediately if it detects a WebDAV request. The default behaviour does *not* do this, however, and it seems wrong to expect everyone who implements __browser_default__ or an IBrowserPublisher adapter to have to do so. My suggestion would be that we simply skip the browserDefault() lookup for WebDAV requests. I don't think it's meaningful to have a browser-default page when looking at objects via WebDAV at all. I can make the change as a bugfix to 2.10, 2.11 and 2.12 if no-one objects. Martin

zope.filerepresentation
by Martin Aspeli 01 Oct '09

01 Oct '09

Hi, I'm doing some work with WebDAV representations in Zope 2, among other things, and I'm trying to see if we should use zope.filerepresentation as the central abstraction for file read/write operations. However, I find myself lacking a couple of things: 1) A way for an IReadFile to return the file's MIME (content) type (for the Content-Type, for example) and an optional filename (for the Conent-Disposition header, for example) 2) A way for an IWriteFile to be told about the MIME type and encoding of the data it is consuming. I know that IFileFactory() contains this, but data is not always going to be written to a new file, so setting this from the factory won't work. 3) I see this comment: # TODO: We will add ILargeReadFile and ILargeWriteFile to efficiently # handle large data. But it seems this was never implemented. I need a way for the IWriteFile.write() to be passed a file-like object (in fact, there's not really any clear notion of what the 'data' parameter is, but I assume it's meant to be a str object), and for IReadFile.read() to return a file stream iterator of some kind instead of the full raw data. I see two options here: - add a new plone.filerepresentation that extends these interfaces - commit some changes to zope.filerepresentation and make a new release of this Since zope.filerepresentation is really *just* interfaces, #2 seems best. Any objections? Here's an initial take on the interfaces: class IReadFile(Interface): """Provide read access to file data """ def read(): """Return the file data as a str """ def size(): """Return the data length """ class ILargeReadFile(IReadFile): """Provide efficient read access to file data """ def getContentType(): """Get the content/MIME type of the file as a string in the form 'major/minor'. Return None if this is not known. """ def getFilename(): """Get the intended file name for this file. Return None if this is not known. """ def getIterator(): """Return an iterable of the file data """ class IWriteFile(Interface): def write(data): """Update the file data """ class ILargeWriteFile(IWriteFile): def writeFile(data, contentType=None, encoding=None): """Update the file data. data is a file-like object containing input data contentType is the content/MIME type of the data as a string in the form 'major/minor'. It may be None if unknown. encoding is the encoding of the string. It may be None if unknown. """ This should be 100% backwards compatible. The downside is that people will need to implement both write() and writeFile() / read() and getIterator() to support both str based and stream based reading and writing, but that's easily addressed with a StringIO. And of course, nothing in the ZTK will actually use these new interfaces, but that could come later. ;) Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.
