delta/python-packages/zope-interface.git/src/zope/interface/declarations.py, branch issue158

Add comment detailing why bases can be set per review.

Make the singleton _empty immutable.

Fixes #158

Move Declaration, Specification and ClassProvides to slots.

2020-01-27T13:40:35+00:00

In a test of 6000 modules that load 2245 InterfaceClass objects and produce 2233 ClassProvides instances, this saves about 1% total memory usage in Python 2.7.

Use tp_members in SpecificationBase and ClassProvidesBase.

Instead of storing 1 and 2 attributes, respectively, in __dict__. This lets us eliminate inst_attr and its use of an undocumented API.

It also helps reign in the size of these objects. Before, on CPython 8, a ClassProvides object that subclasses both SpecificationBase and ClassProvidesBase required 408 bytes: 48 for the object, 360 for the dict.

Now it requires 72 + 232 = 304.

With a bit of work on defining __slots__ in Python, that can be brought much lower still, I think.

zope.security tests pass with this installed.

Test PURE_PYTHON at runtime.

Turns out that the C extensions build and work fine with PyPy, but don't use them by default. Let them
be forced, though.

Tests needed some refactoring to account for the various permutations.

Reorganize the 'declarations' document by functional group.

2018-07-19T17:09:08+00:00

Add cross references and some formatting fixes.

cleanups requested by @tseaver: remove assert from _implements since all its callers already do this guard; be more explicit about ClassType in test_odd_declarations

Enable combined coverage reports under tox and branch coverage

2017-06-14T14:45:49+00:00

Fixes #91

Remove many (or most) now-redundant 'pragma: no cover'.

A few minor test changes to get full branch coverage.

100% coverage (#90)

2017-06-12T14:05:13+00:00

* Get as close to 100% coverage as possible.

Without conflicting with #86.

This is almost entirely trivial changes:

- Make dummy methods that should never be called either raise
  NotImplementedError or call self.fail() in tests.
- Standardize the no-coverage pragma
- Add a few pragmas where coverage varies across
  versions/implementations, mostly for the sake of tox (travis should
  hit them all).

* Convert tox to run the coverage command, like travis. A follow up should have it produce coverage for all python versions/implementations.

Fixes #87

* Adjust coverage config for py2 only tests; fix typo; finish replacing self with cls

Fix C optimizations broken on Py3k.

2016-11-15T19:04:50+00:00

- The bare import of '_zope_c_optimizations' prevented them from being
  used.

- After enabling them via absolute imports, they would fail due to
  http://bugs.python.org/issue15657.

Fixes #60.
