[Zope-dev] zope.interface versions, ZTK 1.0 and later
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
I've been wrestling with Launchpad bugs for zope.interface lately, and
would like to hear from folks about the issues involved.
- %<
Overview
- -
- - Version 3.6.1 was the original ZTK 1.0 version. The substantial
changes since then have been mostly due to issues which showed up
while working on Python3 compatibility:
o LP # 675064: Specify return value type for C optimizations module
init under Python 3 (fixed in zope.interface 3.6.2).
o LP 804951: InterfaceClass instances were unhashable under Python
3.x. (fixed in zope.interface 3.6.4).
The fix here actually provoked the following bugs / fixes:
o LP #811792: work around buggy behavior in some subclasses of
'zope.interface.interface.InterfaceClass', which invoke '__hash__'
before initializing '__module__' and '__name__'.
o Fix Python 2.5 incompatibility introduced in new tests of
'__hash__'.
o LP #825249: Fix test failure (only under 'python setup.py test')
in those same new tests.
At this point, the tests for the trunk (but not the main module
itself) are not Python 2.4 compatible, because they try to test that
a UserWarning is emitted using a 'with' statement.
- - This fix is for non-CPython platforms:
o LP #804832: Do not build C extension under PyPy or Jython.
- - There is one issue not directly related to porting:
o LP #570942: Now correctly compare interfaces from different
modules but with the same names (fixed in 3.6.3).
This fix is in two parts: it corrects extracting the '__module__'
attribute, and adds the missing "rich comparison" operators
('__eq__', '__ne__', '__le__', '__ge__')
The real "slippery slope" was adding '__eq__': it then required
adding '__hash__', because Python's dictionary semantics require that
objects which compare equal also hash equal, which then provokes the
issues with subclasses which stash the instances in a dict before
initializing the '__module__' and '__name__' attributes.
- - The ZTK 1.0 branch was bumped to include zope.interface 3.6.3, which
contained a number of the higer-risk changes, mostly made for porting
purposes.
Proposal
-
- - Revert ZTK 1.0 to use zope.interface 3.6.1. (We can skip this part if
the next step goes quickly).
- - Create a 3.6 branch in SVN, and revert all the post-3.6.1 changes on
it. Release a new 3.6.6 from this branch, possibly after applying a
new, more minimal fix for LP #570942.
- - Bump ZTK 1.0 to use the zope.interface 3.6.6.
- - Freeze development on the 3.6 branch.
- - Release a 3.7.0 version from the trunk, with all the porting changes
intact. Update ZTK 1.1 to use 3.7.0,

Thoughts?
Tres.

[Zope-dev] pagination in bluebream
Hello all, I am trying to list out items in a container, as the number of objects in the container may be large I am trying to paginate them. Basically I am trying to implement something like 'LIMIT' and 'OFFSET' option available in SQL. I found z3c.batching package that does this. For this to work it needs the full list. IMHO, loading the entire list of objects on to the memory doesn't seem to be a good choice. I tried to use zope.catalog to get the object list. But, it has just the _limit option to control the output size. And again manipulating the _limit value to [offset + limit] and then trimming the results doesn't seem to be a clean approach. Is there any other better way of doing this? -- Joshua Immanuel HiPro IT Solutions Private Limited http://hipro.co.in signature.asc Description: This is a digitally signed message part ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )
