Christian Heimes	884332b45a	Add NULL check for gen->gi_code in gen_send_ex() _PyGen_Finalize() checks that gen->gi_code is not NULL before it accesses the flags of the code object. This means that the flag could be NULL. It passes down the generatore to gen_close() and gen_send_ex(). gen_send_ex() did not check for gen->gi_code != NULL. CID 1297900	10 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

Victor Stinner	40ee30181f	Issue #21205 : Add a new ``__qualname__`` attribute to generator, the qualified name, and use it in the representation of a generator (``repr(gen)``). The default name of the generator (``__name__`` attribute) is now get from the function instead of the code. Use ``gen.gi_code.co_name`` to get the name of the code.	12 years ago
Victor Stinner	1310510793	Issue #14432 : Generator now clears the borrowed reference to the thread state Fix a crash when a generator is created in a C thread that is destroyed while the generator is still used. The issue was that a generator contains a frame, and the frame kept a reference to the Python state of the destroyed C thread. The crash occurs when a trace function is setup.	12 years ago

Benjamin Peterson	2afe6aeae8	perform yield from delegation by repeating YIELD_FROM opcode (closes #14230 ) This allows generators that are using yield from to be seen by debuggers.
