Christian Heimes ea837931cf Patch #1691070 from Roger Upole: Speed up PyArg_ParseTupleAndKeywords() and improve error msg
My tests don't show the promised speed up of 10%. The code is as fast as the old code for simple cases and slightly faster for complex cases with several of args and kwargs. But the patch simplifies the code, too.

Eric Smith 3cd8194b9c Added bin() builtin. I'm going to check in the tests in a seperate checkin, because the builtin doesn't need to be ported to py3k, but the tests are missing in py3k and need to be merged there. 2008-02-22 16:30:22 +00:00
Eric Smith 7ef40bf9c7 Trim leading zeros from a floating point exponent, per C99. See issue 1600. As far as I know, this only affects Windows. Add float type 'n' to PyOS_ascii_formatd (see PEP 3101 for 'n' description). 2008-02-20 23:34:22 +00:00
Kristján Valur Jónsson 5299935be5 Perform correct handling of stack overflow for windows: Catch the correct exception code and reset the overflow condition when handled. 2008-02-18 17:40:47 +00:00
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 99af7dbc07 Change r60575 broke test_compile:
there is no need to emit co_lnotab item when both offsets are zeros.

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.

Christian Heimes 422051a367 Patch #1953
I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache

Mark Dickinson 105be7725b Issue #1678380. Fix a bug that identifies 0j and -0j when they appear
in the same code unit. The fix is essentially the same as the fix for a
previous bug identifying 0. and -0.

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.
