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.
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()
compile(). This was due to left-over special-casing before UTF-8 became the
default source encoding.
Closes issue #3574. Thanks to Victor Stinner for help with the patch.
Additional patch by Christian Heimes to deal more cleanly with the
FILE* vs file-descriptor issues.
I cleaned up his code a bit, and moved the lseek() call into import.c.
