* Update repr() and str() of some common objects.issue236Jason Madden2021-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only InterfaceClass got a str, so it now has a distinction. Other objects only got updated reprs. Note: This may potentially break some doctests. In many cases, the ``repr()`` is now something that can be evaluated to produce an equal object. For example, what was previously printed as ``<implementedBy builtins.list>`` is now shown as ``classImplements(list, IMutableSequence, IIterable)``. Fixes #236 Here's a before with ZOPE_INTERFACE_LOG_CHANGED_IRO=1 in BTrees: ``` Object <implementedBy builtins.list> has different legacy and C3 MROs: Legacy RO (len=11) C3 RO (len=11; inconsistent=no) ================================================================================================================================================== <implementedBy builtins.list> <implementedBy builtins.list> <ABCInterfaceClass zope.interface.common.collections.IMutableSequence> <ABCInterfaceClass zope.interface.common.collections.IMutableSequence> <ABCInterfaceClass zope.interface.common.collections.ISequence> <ABCInterfaceClass zope.interface.common.collections.ISequence> <ABCInterfaceClass zope.interface.common.collections.IReversible> <ABCInterfaceClass zope.interface.common.collections.IReversible> <ABCInterfaceClass zope.interface.common.collections.ICollection> <ABCInterfaceClass zope.interface.common.collections.ICollection> <ABCInterfaceClass zope.interface.common.collections.ISized> <ABCInterfaceClass zope.interface.common.collections.ISized> + <ABCInterfaceClass zope.interface.common.collections.IIterable> <ABCInterfaceClass zope.interface.common.collections.IContainer> <ABCInterfaceClass zope.interface.common.collections.IContainer> - <ABCInterfaceClass zope.interface.common.collections.IIterable> <ABCInterfaceClass zope.interface.common.ABCInterface> <ABCInterfaceClass zope.interface.common.ABCInterface> + <implementedBy builtins.object> <InterfaceClass zope.interface.Interface> <InterfaceClass zope.interface.Interface> - <implementedBy builtins.object> Object <ABCInterfaceClass zope.interface.common.mapping.IFullMapping> has different legacy and C3 MROs: Legacy RO (len=18) C3 RO (len=18;

| | | | Also tweak docs.
* Let subclasses of BaseAdapterRegistry customize the data structures.Jason Madden2021-03-031-0/+14
| | | | | | | | | | | | Add extensive tests for this. Fixes #224. Also adds test for, and fixes #227 Add BAR.rebuild() to fix the refcount issue, and to change datatypes. It works by using the new methods allRegistrations() and allSubscriptions() to re-create the data in new data structures. This makes fresh calls to subscribe() and register(). I went this way instead of trying to manually walk the data structures and create them because the logic in those methods is fully tested.

| | | | Mostly formatting. Some interfaces were being documented as clasess, which doesn't work.
* Make Interface.getTaggedValue follow the __iro__.Jason Madden2020-03-182-5/+21
| | | | | | | | 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 Madden2020-03-153-31/+157
| | | | | | | | | | | | | | | | | | | | | | | | 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.
