* Issue #24619: Simplify async/await tokenization.Yury Selivanov2015-07-232-102/+45
| | | | | | | | | | This commit simplifies async/await tokenization in tokenizer.c, tokenize.py & lib2to3/tokenize.py. Previous solution was to keep a stack of async-def & def blocks, whereas the new approach is just to remember position of the outermost async-def block. This change won't bring any parsing performance improvements, but it makes the code much easier to read and validate.
* Issue #24619: New approach for tokenizing async/await.Yury Selivanov2015-07-222-41/+85
| | | | | | | | | | | | | | | | | | | | | This commit fixes how one-line async-defs and defs are tracked by tokenizer. It allows to correctly parse invalid code such as: >>> async def f(): ... def g(): pass ... async = 10 and valid code such as: >>> async def f(): ... async def g(): pass ... await z As a consequence, is is now possible to have one-line 'async def foo(): await ..' functions: >>> async def foo(): return await bar()

| | | | | | | | | | | | | | | | The new parser does not rely on Spark (which is now removed from our repo), uses modern 3.x idioms and is significantly smaller and simpler. It generates exactly the same AST files (.h and .c), so in practice no builds should be affected.

* | Close #16742: Fix misuse of memory allocations in PyOS_Readline()Victor Stinner2013-10-101-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GIL must be held to call PyMem_Malloc(), whereas PyOS_Readline() releases the GIL to read input. The result of the C callback PyOS_ReadlineFunctionPointer must now be a string allocated by PyMem_RawMalloc() or PyMem_RawRealloc() (or NULL if an error occurred), instead of a string allocated by PyMem_Malloc() or PyMem_Realloc(). Fixing this issue was required to setup a hook on PyMem_Malloc(), for example using the tracemalloc module. PyOS_Readline() copies the result of PyOS_ReadlineFunctionPointer() into a new buffer allocated by PyMem_Malloc(). So the public API of PyOS_Readline() does not change.
