* More minor documentation fixups.issue190Jason Madden2020-03-181-12/+13
| | | | Mostly formatting. Some interfaces were being documented as clasess, which doesn't work.
* Make Interface.getTaggedValue follow the __iro__.Jason Madden2020-03-183-28/+203
| | | | | | | | Previously it manually walked up __bases__, meaning the answers could be inconsistent. Fixes #190. Also fixes several minor issues in the documentation, mostly cross-reference related.
* Use C3 (mostly) to compute IRO.issue21Jason Madden2020-03-1515-54/+1001
| | | | | | | | | | | | | | | | | | | | | | | | Fixes #21 The 'mostly' is because interfaces are used in cases that C3 forbids; when there's a conflict, we fallback to the legacy algorithm. It turns out there are few conflicts (13K out of 149K total orderings in Plone). I hoped the fix for #8 might shake out automatically, but it didn't. Optimize the extremely common case of a __bases__ of length one. In the benchmark, 4/5 of the interfaces and related objects have a base of length one. Fix the bad IROs in the bundled ABC interfaces, and implement a way to get warnings or errors. In running plone/buildout.coredev and tracking the RO requests, the stats for equal, not equal, and inconsistent-so-fallback, I got {'ros': 148868, 'eq': 138461, 'ne': 10407, 'inconsistent': 12934} Add the interface module to the Attribute str. This was extremely helpful tracking down the Plone problem; IDate is defined in multiple modules.
* Add additional low-level tests for super() unwrapping.Jason Madden2020-03-101-1/+38

* Remove unused str variablesJason Madden2020-03-101-15/+8
| | | | | The DEFINE_STRING macro prevents the linter from seeing them as unused so I temporarily redefined it to find all such variables.
* Make provided/implementedBy and adapter registries respect super().issue11Jason Madden2020-03-095-45/+647
| | | | | | | | | | | | | | | | | | | | | | | | The query functions now start by looking at the next class in the MRO (interfaces directly provided by the underlying object are not found). Adapter registries automatically pick up providedBy change to start finding the correct implementations of adapters, but to make that really useful they needed to change to unpack super() arguments and pass __self__ to the factory. Fixes #11 Unfortunately, this makes PyPy unable to build the C extensions. Additional crash-safety for adapter lookup. Make the C functions get the cache only after resolving the ``required`` into a tuple, in case of side-effects like...clearing the cache. This could lead to the ``cache`` object being deallocated before we used it. Drop the ``tuplefy`` function in favor of a direct call to ``PySequence_Tuple``. It's what the ``tuple`` constructor would do anyway and saves a few steps. Make sure that getting ``providedBy(super())`` and ``implementedBy(super())`` have no side effects.

| | | | | | | | | | | | | | 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

* The _empty singleton has no-op subscribe/unsubscribe methods.issue162Jason Madden2020-01-283-9/+43
| | | | | | | | 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.

* Use tp_members in SpecificationBase and ClassProvidesBase.Jason Madden2020-01-234-232/+275
| | | | | | | | | | | | 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.
