Brett Cannon e974689038 Re-implement the 'warnings' module in C. This allows for usage of the
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.

Closes issue #1631171.

Christian Heimes 7a98d2730c Applied patch #2617 from Frank Wierzbicki wit some extras from me
-J and -X are now reserved for Jython and non-standard arguments (e.g. IronPython). I've added some extra comments to make sure the reservation don't get missed in the future.

Neal Norwitz d183bdd6fb Revert r61969 which added casts to Py_CHARMASK to avoid compiler warnings.
Rather than sprinkle casts throughout the code, change Py_CHARMASK to
always cast it's result to an unsigned char.  This should ensure we
do the right thing when accessing an array with the result.

Christian Heimes 3c60833e1e Patch #2477: Added from __future__ import unicode_literals
The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.

This work is substantially Anthony Baxter's, from issue

and added the test cases.  I also created issue 2412,
which is to check for 2to3's behavior with the print
function.  I also added myself to ACKS.

Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Amaury Forgeot d'Arc 6fd03bb607 #1750076: Debugger did not step on every iteration of a while statement.
The mapping between bytecode offsets and source lines (lnotab) did not contain
an entry for the beginning of the loop.

Now it does, and the lnotab can be a bit larger:
in particular, several statements on the same line generate several entries.
However, this does not bother the settrace function, which will trigger only
one 'line' event.

The lnotab seems to be exactly the same as with python2.4.

Amaury Forgeot d'Arc 16570f59ca #1920: when considering a block starting by "while 0", the compiler optimized the
whole construct away, even when an 'else' clause is present::

    while 0:
        print("no")
    else:
        print("yes")

did not generate any code at all.

Now the compiler emits the 'else' block, like it already does for 'if' statements.

Will backport.

Gregory P. Smith 2778c999e3 Provide a sanity check during PyThreadState_DeleteCurrent() and
PyThreadState_Delete() to avoid an infinite loop when the tstate list
is messed up and has somehow becomes circular and does not contain the
current thread.

I don't know how this happens but it does, *very* rarely.  On more than
one hardware platform.  I have not been able to reproduce it manually.

Attaching to a process where its happening: it has always been in an
infinite loop over a single element tstate list that is not the tstate
we're looking to delete.  It has been in t_bootstrap()'s call to
PyThreadState_DeleteCurrent() as a pthread is exiting.

Jeffrey Yasskin 9871d8fe22 Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
 * Revert round to its 2.6 behavior (half away from 0).
 * Because round, floor, and ceil always return float again, it's no
   longer necessary to have them delegate to __xxx___, so I've ripped
   that out of their implementations and the Real ABC. This also helps
   in implementing types that work in both 2.6 and 3.0: you return int
   from the __xxx__ methods, and let it get enabled by the version
   upgrade.
 * Make pow(-1, .5) raise a ValueError again.

Amaury Forgeot d'Arc e0b7695286 Partial port of r59682 from py3k.
On Windows, when import fails to load a dll module, the message says
"error code 193" instead of a more informative text.

It turns out that FormatMessage needs additional parameters for some error codes.
For example: 193 means "%1 is not a valid Win32 application".
Since it is impossible to know which parameter to pass, we use
FORMAT_MESSAGE_IGNORE_INSERTS to get the raw message, which is still better
than the number.

Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.

Amaury Forgeot d'Arc 025c347d61 Issue #1402: PyInterpreterState_Clear() may still invoke user code

Amaury Forgeot d'Arc 0d75f09177 Merge from py3k branch:
Correction for issue1265 (pdb bug with "with" statement).

When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set.  This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.

It is necessary to save/restore the exception around the call to the trace
function.

This happens a lot with py3k: isinstance() of an ABCMeta instance runs
    def __instancecheck__(cls, instance):
        """Override for isinstance(instance, cls)."""
        return any(cls.__subclasscheck__(c)
                   for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.

Backport candidate, even if the case is less frequent in 2.5.

Kristján Valur Jónsson f030394de3 Fix problems in x64 build that were discovered by the testsuite:
- Reenable modules on x64 that had been disabled aeons ago for Itanium.
- Cleared up confusion about compilers for 64 bit windows.  There is only Itanium and x64.  Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
- Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
- Fixed thread_nt.h.  The emulated InterlockedCompareExchange function didn´t work on x64, probaby due to the lack of a "volatile" specifier.  Anyway, win95 is no longer a target platform.
- Itertools module used wrong constant to check for overflow in count()
- PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
- PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.

With these changes, the x64 passes the testsuite, for those modules present.

Neal Norwitz aa754b70b0 Remove unused file spotted by Paul Hankin 2007-03-21 06:39:48 +00:00
Jeremy Hylton dd2cf1cb84 Clean up formatting of this file.
The file should now follow PEP 7, except that it uses 4 space indents
(in the style of Py3k).  This particular code would be really hard to
read with the regular tab idents.

Other changes:
 - reflow long lines
 - change multi-line conditionals to have test at end of line

case, even when converting the value to a string failed.

Georg Brandl 871f1bc601 Backport from Py3k branch:
Patch #1591665: implement the __dir__() special function lookup in PyObject_Dir.

Had to change a few bits of the patch because classobjs and __methods__ are still
in Py2.6.

Georg Brandl aa2321b0f8 Patch #703779: unset __file__ in __main__ after running a file. This
makes the filenames the warning module prints much more sensible when
a PYTHONSTARTUP file is used.

Georg Brandl 49aafc9f2c Variant of patch #697613: don't exit the interpreter on a SystemExit
exception if the -i command line option or PYTHONINSPECT environment
variable is given, but break into the interactive interpreter just like
on other exceptions or normal program exit.

Jeremy Hylton 819de6ce20 tabify
Note that ast.c still has a mix of tabs and spaces, because it
attempts to use four-space indents for more of the new code.

Neal Norwitz f83b751f4b SF #1669182, 2.5 was already fixed. Just assert in 2.6 since string exceptions
are gone.

Neal Norwitz 88516a6039 When printing an unraisable error, don't print exceptions. before the name.
This duplicates the behavior whening normally printing exceptions.

Neal Norwitz 7b7d1c8282 Fix a couple of problems in generating the AST code:
* use %r instead of backticks since backticks are going away in Py3k
 * PyArena_Malloc() already sets PyErr_NoMemory so we don't need to do it again
 * the signature for ast2obj_int incorrectly used a bool, rather than a long

Jeremy Hylton c5ceb251b3 Fix crash in exec when unicode filename can't be decoded.
I can't think of an easy way to test this behavior.  It only occurs
when the file system default encoding and the interpreter default
encoding are different, such that you can open the file but not decode
its name.

Brett Cannon 0db62aaf09 Modify Parser/asdl_c.py so that the __version__ number for Python/Python-ast.c
is specified at the top of the file.  Also add a note that Python/Python-ast.c
needs to be committed separately after a change to the AST grammar to capture
the revision number of the change (which is what __version__ is set to).
