Raymond Hettinger	ac2ef65c32	Make the unicode equality test an external function rather than in-lining it. The real benefit of the unicode specialized function comes from bypassing the overhead of PyObject_RichCompareBool() and not from being in-lined (especially since there was almost no shared data between the caller and callee). Also, the in-lining was having a negative effect on code generation for the callee.	11 years ago

Raymond Hettinger	3c1f52e829	Call set_lookkey() directly to avoid unnecessary memory spills and reloads.	11 years ago
Raymond Hettinger	15f0869609	Move insertion resize logic into set_insert_key(). Simplifies the code a little bit and does the resize check only when a new key is added (giving a small speed up in the case where the key already exists). Fixes possible bug in set_merge() where the set_insert_key() call relies on a big resize at the start to make enough room for the keys but is vulnerable to a comparision callback that could cause the table to shrink in the middle of the merge. Also, changed the resize threshold from two-thirds of the mask+1 to just two-thirds. The plus one offset gave no real benefit (afterall, the two-thirds mark is just a heuristic and isn't a precise cut-off).	11 years ago

Yury Selivanov	5376ba9630	Issue #24400 : Introduce a distinct type for 'async def' coroutines. Summary of changes: 1. Coroutines now have a distinct, separate from generators type at the C level: PyGen_Type, and a new typedef PyCoroObject. PyCoroObject shares the initial segment of struct layout with PyGenObject, making it possible to reuse existing generators machinery. The new type is exposed as 'types.CoroutineType'. As a consequence of having a new type, CO_GENERATOR flag is no longer applied to coroutines. 2. Having a separate type for coroutines made it possible to add an __await__ method to the type. Although it is not used by the interpreter (see details on that below), it makes coroutines naturally (without using __instancecheck__) conform to collections.abc.Coroutine and collections.abc.Awaitable ABCs. [The __instancecheck__ is still used for generator-based coroutines, as we don't want to add __await__ for generators.] 3. Add new opcode: GET_YIELD_FROM_ITER. The opcode is needed to allow passing native coroutines to the YIELD_FROM opcode. Before this change, 'yield from o' expression was compiled to: (o) GET_ITER LOAD_CONST YIELD_FROM Now, we use GET_YIELD_FROM_ITER instead of GET_ITER. The reason for adding a new opcode is that GET_ITER is used in some contexts (such as 'for .. in' loops) where passing a coroutine object is invalid. 4. Add two new introspection functions to the inspec module: getcoroutinestate(c) and getcoroutinelocals(c). 5. inspect.iscoroutine(o) is updated to test if 'o' is a native coroutine object. Before this commit it used abc.Coroutine, and it was requested to update inspect.isgenerator(o) to use abc.Generator; it was decided, however, that inspect functions should really be tailored for checking for native types. 6. sys.set_coroutine_wrapper(w) API is updated to work with only native coroutines. Since types.coroutine decorator supports any type of callables now, it would be confusing that it does not work for all types of coroutines. 7. Exceptions logic in generators C implementation was updated to raise clearer messages for coroutines: Before: TypeError("generator raised StopIteration") After: TypeError("coroutine raised StopIteration")	11 years ago
