delta/python-packages/zope-interface.git/src, branch issue162 github.com: zopefoundation/zope.interface.git The _empty singleton has no-op subscribe/unsubscribe methods. 2020-01-28T22:04:31+00:00 Jason Madden jamadden@gmail.com 2020-01-28T22:04:31+00:00 97997956d1a17a0cfb064dfe0487291e8f8ee181 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.

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

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

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.
