Mark Dickinson 18cfada1ea Remove restriction on precision when formatting floats. This is the 
first step towards removing the %f -> %g switch (see issues 7117,
5859).

Mark Dickinson bd15a06fd3 Issue #7117, continued: Change round implementation to use the correctly-rounded 
string <-> float conversions;  this makes sure that the result of the round
operation is correctly rounded, and hence displays nicely using the new float
repr.

 2009-10-11 21:03:26 +00:00
Amaury Forgeot d'Arc d0052d17b1 #1571184: makeunicodedata.py now generates the functions _PyUnicode_ToNumeric, 
_PyUnicode_IsLinebreak and _PyUnicode_IsWhitespace.

It now also parses the Unihan.txt for numeric values.
 2009-10-06 19:56:32 +00:00
Mark Dickinson 71adc9328d Style/consistency/nano-optimization nit: replace occurrences of 
(high_bits << PyLong_SHIFT) + low_bits with
  (high_bits << PyLong_SHIFT) | low_bits
in Objects/longobject.c.  Motivation:
 - shouldn't unnecessarily mix bit ops with arithmetic ops (style)
 - this pattern should be spelt the same way thoughout (consistency)
 - it's very very very slightly faster: no need to worry about
   carries to the high digit (nano-optimization).

Kristján Valur Jónsson 02ca57ce4c http://bugs.python.org/issue6836 
The debug memory api now keeps track of which external API (PyMem_* or PyObject_*) was used to allocate each block and treats any API violation as an error.  Added separate _PyMem_DebugMalloc functions for the Py_Mem API instead of having it use the _PyObject_DebugMalloc functions.

Mark Dickinson aa2adc828a Issue #6713: Improve performance of str(n) and repr(n) for integers n

_PyLong_Format.  (Backport of r74851 from py3k.)
 2009-09-16 22:10:56 +00:00
Georg Brandl 0674d3fb5f #6844: do not emit DeprecationWarnings on access if Exception.message has been set by the user. 
This works by always setting it in __dict__, except when it's implicitly set in __init__.

Benjamin Peterson 24d9175ebe must use _PyThreadState_Current so it isn't checked for NULL #6530 2009-07-21 14:08:40 +00:00
Alexandre Vassalotti fd00916c2e Grow the allocated buffer in PyUnicode_EncodeUTF7 to avoid buffer overrun. 
Without this change, test_unicode.UnicodeTest.test_codecs_utf7 crashes in
debug mode. What happens is the unicode string u'\U000abcde' with a length
of 1 encodes to the string '+2m/c3g-' of length 8. Since only 5 bytes is
reserved in the buffer, a buffer overrun occurs.

Amaury Forgeot d'Arc 595f7a5bf9 #2016 Fix a crash in function call when the **kwargs dictionary is mutated 
during the function call setup.

This even gives a slight speedup, probably because tuple allocation
is faster than PyMem_NEW.

Jeffrey Yasskin 655d835415 Issue #6042: 
lnotab-based tracing is very complicated and isn't documented very well.  There
were at least 3 comment blocks purporting to document co_lnotab, and none did a
very good job. This patch unifies them into Objects/lnotab_notes.txt which
tries to completely capture the current state of affairs.

I also discovered that we've attached 2 layers of patches to the basic tracing
scheme. The first layer avoids jumping to instructions that don't start a line,
to avoid problems in if statements and while loops.  The second layer
discovered that jumps backward do need to trace at instructions that don't
start a line, so it added extra lnotab entries for 'while' and 'for' loops, and
added a special case for backward jumps within the same line. I replaced these
patches by just treating forward and backward jumps differently.

Jeffrey Yasskin c8d30fec16 Fix issue #1689458 by teaching frame_setlineno how to jump to the first line of 
a code object.
 2009-05-20 17:57:57 +00:00
Jeffrey Yasskin 61328eef1f While I was modifying test_trace, it threw an exception when I accidentally 
made it try to set the line number from the trace callback for a 'call' event.
This patch makes the error message a little more helpful in that case, and
makes it a little less likely that a future editor will make the same mistake
in test_trace.

Jeffrey Yasskin f7f858d141 Issue 5954, PyFrame_GetLineNumber: 
Most uses of PyCode_Addr2Line
(http://www.google.com/codesearch?q=PyCode_Addr2Line) are just trying to get
the line number of a specified frame, but there's no way to do that directly.
Forcing people to go through the code object makes them know more about the
guts of the interpreter than they should need.

The remaining uses of PyCode_Addr2Line seem to be getting the line from a
traceback (for example,
http://www.google.com/codesearch/p?hl=en#u_9_nDrchrw/pygame-1.7.1release/src/base.c&q=PyCode_Addr2Line),
which is replaced by the tb_lineno field.  So we may be able to deprecate
PyCode_Addr2Line entirely for external use.
 2009-05-08 22:23:21 +00:00
Jeffrey Yasskin 1aa4700234 PyCode_NewEmpty: 
Most uses of PyCode_New found by http://www.google.com/codesearch?q=PyCode_New
are trying to build an empty code object, usually to put it in a dummy frame
object. This patch adds a PyCode_NewEmpty wrapper which lets the user specify
just the filename, function name, and first line number, instead of also
requiring lots of code internals.

Eric Smith a985a3aee4 Issue #5920: Changed format.__float__ and complex.__float__ to use a precision of 12 when using the empty presentation type.

Georg Brandl ba68a99656 #5929: fix signedness warning. 2009-05-05 09:19:43 +00:00
R. David Murray 7ba8e1cbfd Fix issue 5890: (property subclass shadows __doc__ string) by inserting 
the __doc__ into the subclass instance __dict__.  The fix refactors
property_copy to call property_init in such a way that the __doc__
logic is re-executed correctly when getter_doc is 1, thus simplifying
property_copy.

Eric Smith 068f06568b Issue #5835, deprecate PyOS_ascii_formatd. 
If anyone wants to clean up the documentation, feel free. It's my first documentation foray, and it's not that great.

Eric Smith ebafbb705c Fixed issue 5782: formatting with commas didn't work if no specifier type code was given. 2009-04-22 16:20:47 +00:00
Eric Smith aca19e6a74 Backport of some of the work in r71665 to trunk. This reworks much of 
int, long, and float __format__(), and it keeps their implementation
in sync with py3k.

Also added PyOS_double_to_string. This is the "fallback" version
that's also available in trunk, and should be kept in sync with that
code. I'll add an issue to document PyOS_double_to_string in the C
API.

There are many internal cleanups. Externally visible changes include:

- Implement PEP 378, Format Specifier for Thousands Separator, for
  floats, ints, and longs.

- Issue #5515: 'n' formatting for ints, longs, and floats handles
  leading zero formatting poorly.

- Issue #5772: For float.__format__, don't add a trailing ".0" if
  we're using no type code and we have an exponent.

Mark Dickinson 6736cf8d20 Issue #3166: Make long -> float (and int -> float) conversions 
correctly rounded, using round-half-to-even.  This ensures that the
value of float(n) doesn't depend on whether we're using 15-bit digits
or 30-bit digits for Python longs.

Antoine Pitrou f8387af262 Issue #4688: Add a heuristic so that tuples and dicts containing only 
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.

(trivia: this makes the "binary_trees" benchmark from the Computer Language
Shootout 40% faster)

Mark Dickinson 0b666bfdf9 Issue #5512: speed up the long division algorithm for Python longs. 
The basic algorithm remains the same; the most significant speedups
come from the following three changes:

  (1) normalize by shifting instead of multiplying and dividing
  (2) the old algorithm usually did an unnecessary extra iteration of
      the outer loop; remove this.  As a special case, this means that
      long divisions with a single-digit result run twice as fast as
      before.
  (3) make inner loop much tighter.

Various benchmarks show speedups of between 50% and 150% for long
integer divisions and modulo operations.

Eric Smith 6f42edb682 Issue 5237, Allow auto-numbered replacement fields in str.format() strings. 
For simple uses for str.format(), this makes the typing easier. Hopfully this
will help in the adoption of str.format().

For example:
'The {} is {}'.format('sky', 'blue')

You can mix and matcth auto-numbering and named replacement fields:
'The {} is {color}'.format('sky', color='blue')

But you can't mix and match auto-numbering and specified numbering:
'The {0} is {}'.format('sky', 'blue')
ValueError: cannot switch from manual field specification to automatic field numbering

Will port to 3.1.
