Thomas Wouters f7f438ba3b SF patch #1438387, PEP 328: relative and absolute imports. 
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
   the import. Only passed to __import__ when it's not -1.

 - __import__() takes an optional 5th argument for the same thing; it
   __defaults to -1 (old semantics: try relative, then absolute)

 - 'from . import name' imports name (be it module or regular attribute)
   from the current module's *package*. Likewise, 'from .module import name'
   will import name from a sibling to the current module.

 - Importing from outside a package is not allowed; 'from . import sys' in a
   toplevel module will not work, nor will 'from .. import sys' in a
   (single-level) package.

 - 'from __future__ import absolute_import' will turn on the new semantics
   for import and from-import: imports will be absolute, except for
   from-import with dots.

Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.

Guido van Rossum baf3eb2410 Forgot to explain the effect of the new opcode. 
Sigh -- we really should have one place for all opcode metadata.

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).

Neal Norwitz 9aaad88393 Even though we don't currently use unicode or complex numbers in the test, 
be complete when when checking types.

Yield cannot be tested outside a function, so add a comment to that effect.

Brett Cannon be66e943c2 Don't filter out OverflowWarning; should be a test failure if it is raised by 
the interpreter in 2.5 .

Martin v. Löwis 02cbf4ae4b More unconsting. 2006-02-27 17:20:04 +00:00
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.

Anthony Baxter 322a23f21b regenerated. please read PEP 306 when changing Python's grammar! 2006-02-27 06:49:54 +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.

Brett Cannon 23b0dc5053 Remove line meant to test trailing whitespace since that kind of whitespace is 
automatically removed.

Also annotate what each line is meant to test.
