Brett Cannon a7446e3438 Check the return code for PyErr_Warn() when warning about raising string 
exceptions.  This was triggered when 'warnings' had a filter set to "error"
that caught the string exception deprecation warning.

Tim Peters a7444f47b2 PyErr_ProgramText(): Grrrrrr. 
In a Windows debug build, trying to open a file using
an empty string as the name causes assertion death
inside MS's C runtime code.  We probably need to worm
around that in many places.  I'm worming around it here
to stop the new test_with.py from assert-dying in the
Windows debug build (it calls compile() with an empty
string for "the file name", which indirectly leads to
C-level code in Python trying to fopen("", "r")).

Guido van Rossum c2e20744b2 PEP 343 -- the with-statement. 
This was started by Mike Bland and completed by Guido
(with help from Neal).

This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.

There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).

Jeremy Hylton c7d37264bb Fix parsing of subscriptlist. 
(Armin's SF bug report).
d = {}
d[1,] = 1
Now handled correctly

Tim Peters f4e6928c4d Patch 1413181, by Gabriel Becedillas. 
PyThreadState_Delete():  if the auto-GIL-state machinery knows about
the thread state, forget it (since the thread state is being deleted,
continuing to remember it can't help, but can hurt if another thread
happens to get created with the same thread id).

I'll backport to 2.4 next.

Thomas Wouters 8622e93eab And some more cleanup. 2006-02-27 17:14:45 +00:00

Thomas Wouters fa443cda87 Fix assertion errors in debug build, brought on by PEP 308 patch. 2006-02-27 15:43:57 +00:00
Martin v. Löwis 577b5b960d Create _ast module. 
Cleanup Python-ast.c generation.
 2006-02-27 15:23:19 +00:00
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 59090a7334 Oops, I forgot to check this in with the change to Grammar/Grammar. 
Implement change suggested by Jiwon Seo on python-dev.
['(' gen_for ')'] is redundant with test, so remove it.

Neal Norwitz 9a27617239 Based on discussion with Martin and Thomas on python-checkins 
add a Py_SAFE_DOWNCAST() to make the code correct.
 2006-02-20 18:57:39 +00:00
Neal Norwitz 20dd93f427 Fix compiler warning on amd64. We can't use zd here since this is 
ultimately going to snprintf() not the python string formatter.  Right?

Thomas Wouters 03ca23d892 Explain the clearing of the stack in a comment in Python/ceval.c's 
call_function(), rather than commenting on the lack of an explanation in a
comment.

Brett Cannon 82a9394237 Add doc discussing how AST compiler is structured and designed. 
It is out of date, though, thanks to lacking info on the arena API.  It also
should eventually be removed in favor of updating PEP 339.

Jeremy Hylton c960f26044 Improved handling of syntax errors. 
Expand set of errors caught in set_context().  Some new errors, some
old error messages changed for consistency.

Fixed error checking in generator expression code.  The first set of
tests were impossible condition given the grammar.  In general, the
ast code uses REQ() for those sanity checks.

Fix some error handling for augmented assignments.  As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it.  Should come back to this.

Add note to Grammar that yield expression is a special case.

Add doctest cases for SyntaxErrors raised by ast.c.

Neal Norwitz 1ac754fa10 Check return result from Py_InitModule*(). This API can fail. 
Probably should be backported.

Tim Peters e93e64fb1a Repair bizarre indentation created by VC 7.1. 2006-01-08 02:28:41 +00:00
Tim Peters 5db42c4c50 alias_for_import_name(): Dueling compiler warnings ;-) 
Squash new warnings from VC 7.1 about mixing signed and
unsigned types in comparisons.  I can see why `len` was
changed to size_t here, but don't see why `i` was also
changed.  Change `i` back to int.
 2006-01-08 02:25:34 +00:00
Tim Peters d8fe7ab711 analyze_cells(): This no longer compiled under VC 7.1. 
Move declaration of local `flags` to top of block.
