Fix repr of "Attribute" to look like before

2020-02-16T14:49:31+00:00

and as usual in Python.

Make verification errors more readable and useful.

2020-02-07T16:59:11+00:00

Eliminate the trailing newlines and blank spaces (the code called them
"a stupid artifact").

Include the name of the defining interface (so the user can easily look up
any requirements on the attribute) and, for methods, the expected
signature (no more guessing about how many arguments are required!).

This is implemented by giving Attribute and Method useful reprs and strs.
Previously, they just had the defaults.

Fixes #170

Fix verification for methods of builtin types with pseudo-default arguments on Pypy

2020-02-06T15:02:56+00:00

On PyPy2, they are ignored (like on CPython), but on PyPy3 they can
actually be validated.

Fixes #118

Add all to all modules.

2020-02-05T14:12:53+00:00

Fixes #153

The items that went in each ``__all__`` are based on what is
documented:

 $ rg --no-filename 'import' docs/ -trst | tr -s "[:blank:]" | sort | uniq | grep zope
 >>> from pprint import pprint
 >>> from zope.interface import *
 >>> from zope.interface import Interface
 >>> from zope.interface import Interface, Attribute, implementer
 >>> from zope.interface import alsoProvides
 >>> from zope.interface import classImplements
 >>> from zope.interface import classImplementsOnly
 >>> from zope.interface import directlyProvidedBy
 >>> from zope.interface import directlyProvides
 >>> from zope.interface import implementedBy
 >>> from zope.interface import implementer
 >>> from zope.interface import implementer_only

 >>> import zope.interface

And also some personal judgement about what the public API is that I'm
more than happy to have reviewed.

The _empty singleton has no-op subscribe/unsubscribe methods.

Turns out they can be called in some very strange error cases. See #162 and #163 for details.

This should fix #162 (at least the provided test case, five.intid, passes now).

It also does enough work on #163 that (a) the test can be written and run in pure-python mode, which was needed to debug it and (b) five.intid runs in pure-python mode (well, with a bunch of other small hacks to Acquisition, ExtensionClass, DocumentTemplate and AccessControl), but I won't claim that it fully fixes #163. For one thing, there are no specific tests. For another, I see more such differences.

Remove support for hashing uninitialized interfaces.

Fixes #157

Avoid allocating space for tagged values unless they're used. This saves another few percent.

2020-01-27T13:43:27+00:00

Specifications with no dependents are common (4700 out of 7000 in this example), so avoid allocating a WeakKeyDictionary until needed.

2020-01-27T13:40:36+00:00

This saves another 2% or so.

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.
