bpo-35798: Add test.support.check_syntax_warning(). (#11895)
It checks that a SyntaxWarning is raised when compile specified
statement, that it is raised only once, that it is converted to
a SyntaxError when raised as exception, and that both warning and
exception objects have corresponding attributes.

David Cuthbert fd97d1f1af bpo-32117: Allow tuple unpacking in return and yield statements (gh-4509)
Iterable unpacking is now allowed without parentheses in yield and return
statements, e.g. ``yield 1, 2, 3, *rest``. Thanks to David Cuthbert for the
change and jChapman for added tests.

Serhiy Storchaka 73a7e9b10b bpo-10544: Deprecate "yield" in comprehensions and generator expressions. (GH-4579)
The current behaviour of yield expressions inside comprehensions  and
generator expressions is essentially an accident of implementation - it
arises implicitly from the way the compiler handles yield expressions inside
nested functions and generators.

Since the current behaviour wasn't deliberately designed, and is inherently
confusing, we're deprecating it, with no current plans to reintroduce it.
Instead, our advice will be to use a named nested generator definition
for cases where this behaviour is desired.

Victor Stinner 15a3095d64 compiler: don't emit SyntaxWarning on const stmt
Issue #26204: the compiler doesn't emit SyntaxWarning warnings anymore when
constant statements are ignored.
2016-02-08 22:45:06 +01:00
Victor Stinner a2724095cd compiler now ignores constant statements
The compile ignores constant statements and emit a SyntaxWarning warning.

Don't emit the warning for string statement because triple quoted string is a
common syntax for multiline comments.

Don't emit the warning on ellipis neither: 'def f(): ...' is a legit syntax for
abstract functions.

Changes:

* test_ast: ignore SyntaxWarning when compiling test statements. Modify
  test_load_const() to use assignment expressions rather than constant
  expression.
* test_code: add more kinds of constant statements, ignore SyntaxWarning when
  testing that the compiler removes constant statements.
* test_grammar: ignore SyntaxWarning on the statement "1"

Yury Selivanov 8fb307cd65 Issue #24619: New approach for tokenizing async/await.
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()

Zachary Ware 38c707e7e0 Issue #21741: Update 147 test modules to use test discovery.
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.
