Neal Norwitz 3b3aae013b Bug #1520864 (again): unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again.

Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.

for the bogus failure.

Neal Norwitz 33b730e33c Fix SF bug #1458903 with AST compiler.
def foo((x)): was getting recognized as requiring tuple unpacking
which is not correct.

Add tests for this case and the proper way to unpack a tuple of one:
	def foo((x,)):

test_inpsect was incorrect before.  I'm not sure why it was passing,
but that has been corrected with a test for both functions above.
This means the test (and therefore inspect.getargspec()) are broken in 2.4.

Thomas Wouters dca3b9c797 PEP 308 implementation, including minor refdocs and some testcases. It
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

Neal Norwitz f8d403dd97 SF #1377897, Bus error in ast
If a line had multiple semi-colons and ended with a semi-colon, we would
loop too many times and access a NULL node.  Exit the loop early if
there are no more children.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Raymond Hettinger 354433a59d SF patch #872326: Generator expression implementation
(Code contributed by Jiwon Seo.)

The documentation portion of the patch is being re-worked and will be
checked-in soon.  Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).

The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch.  Further additions are
welcome from everyone.  Please stress test this new feature as much as
possible before the alpha release.

Guido van Rossum 6c9e130524 - Removed FutureWarnings related to hex/oct literals and conversions
and left shifts.  (Thanks to Kalle Svensson for SF patch 849227.)
  This addresses most of the remaining semantic changes promised by
  PEP 237, except for repr() of a long, which still shows the trailing
  'L'.  The PEP appears to promise warnings for operations that
  changed semantics compared to Python 2.3, but this is not
  implemented; we've suffered through enough warnings related to
  hex/oct literals and I think it's best to be silent now.

Jeremy Hylton 4d508adae3 Fix for SF [ 734869 ] Lambda functions in list comprehensions
The compiler was reseting the list comprehension tmpname counter for each function, but the symtable was using the same counter for the entire module.  Repair by move tmpname into the symtable entry.

Bugfix candidate.

Guido van Rossum 66b1259dbc SF #660455 : patch by NNorwitz.
"Unsigned" (i.e., positive-looking, but really negative) hex/oct
constants with a leading minus sign are once again properly negated.
The micro-optimization for negated numeric constants did the wrong
thing for such hex/oct constants.  The patch avoids the optimization
for all hex/oct constants.

This needs to be backported to Python 2.2!
2003-02-12 16:57:47 +00:00
Guido van Rossum f0253f2bc5 Restore the hex/oct constant tests that Barry commented out for fear
of FutureWarnings.  Added a comment explaining the situation.

Barry Warsaw 18bd11205d Fixed three exceptions in the Plain integers test, although I'm not
sure these are the best fixes.

- Test maxint-1 against the negative octal constant -020000000000

- Comment out the tests for oct -1 and hex -1, since 037777777777 and
  0xffffffff raise FutureWarnings now and in Python 2.4 those
  constants will produce positive values, not negative values.  So the
  existing test seems to test something that won't be true in 2.4.

Barry Warsaw 266e6b1f4b Quite down some FutureWarnings. 2002-08-28 16:36:11 +00:00
Barry Warsaw 408b6d34de Complete the absolute import patch for the test suite. All relative
imports of test modules now import from the test package.  Other
related oddities are also fixed (like DeprecationWarning filters that
weren't specifying the full import part, etc.).  Also did a general
code cleanup to remove all "from test.test_support import *"'s.  Other
from...import *'s weren't changed.

Jeremy Hylton 7d3dff2b39 SF patch [ #468662 ] Allow jython to complete test_grammar
The behavior of co_varnames in the presence of nested argument tuples
is not consistent across Python and Jython.  Test each platform
separately.

Thomas Wouters 80d373cbd0 Test case for SF bugs #463359 and #462937, added to test_grammar for lack of

something in this area changes!

Jeremy Hylton e241e29f3d Add test for a list comprehension that is nested in the left-hand part
of another list comp.  This caused crashes reported as SF bugs 409230
and 407800.

Note that the new tests are in a function so that the name lookup code
isn't affected by how many *other* list comprehensions are in the same
scope.

2001-02-01 22:48:12 +00:00
Jeremy Hylton 483638c9a8 Undo recent change that banned using import to bind a global, as per
discussion on python-dev.  'from mod import *' is still banned except
at the module level.

Fix value for special NOOPT entry in symtable.  Initialze to 0 instead
of None, so that later uses of PyInt_AS_LONG() are valid.  (Bug
reported by Donn Cave.)

Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Marc-André Lemburg d1ba443206 This patch adds a new Python C API called PyString_AsStringAndSize()
which implements the automatic conversion from Unicode to a string
object using the default encoding.

The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.

As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.
