Mark Dickinson 18a818bc63 Fix multiple uses of variable 'L' in _Py_dg_strtod, where one use requires an unsigned long and the other a signed long. See also r77421. 2010-01-16 18:06:17 +00:00
Mark Dickinson 811ff822f8 Issue #7632: Fix one more case of incorrect rounding for str -> float 
conversion (see bug 5 in the issue tracker).
 2010-01-16 17:57:49 +00:00
Mark Dickinson 476279f18b Issue #7632: Fix a serious wrong output bug for string -> float conversion. 
Also remove some now unused variables, and add comments clarifying the
possible outputs of the parsing section of _Py_dg_strtod.  Thanks
Eric Smith for reviewing.

Brett Cannon 0bc77474aa Remove C++/C99-style comments. 2010-01-15 01:31:45 +00:00
Brett Cannon 3ffa43db48 The silencing of DeprecationWarning was not taking -3 into consideration. Since 
Py3K warnings are DeprecationWarning by default this was causing -3 to
essentially be a no-op. Now DeprecationWarning is only silenced if -3 is not
used.

Closes issue #7700. Thanks Ezio Melotti and Florent Xicluna for patch help.

Mark Dickinson f8747c1f12 Issue 7632: fix incorrect rounding for long input strings with values very close to a power of 2. (See Bug 4 in the tracker discussion.) 2010-01-14 14:40:20 +00:00
Mark Dickinson 50b60c612e Issue 7632: fix a dtoa.c bug (bug 6) causing incorrect rounding. Tests to follow. 2010-01-14 13:14:49 +00:00
Mark Dickinson 03774fac62 Fix off-by-one error introduced in r77483. I have a test for this, but it currently fails due to a different dtoa.c bug; I'll add the test once that bug is fixed. 2010-01-14 13:02:36 +00:00
Mark Dickinson d2a9940acb More dtoa.c cleanup; remove the need for bc.dplen, bc.dp0 and bc.dp1. 2010-01-13 22:20:10 +00:00

Mark Dickinson 6e0d3d67fb Simplify and annotate the bigcomp function, removing unused special cases. 2010-01-13 20:55:03 +00:00
Mark Dickinson 5818e01253 Clarify that sulp expects a nonnegative input, but that +0.0 is fine. 2010-01-13 19:02:37 +00:00
Mark Dickinson b26d56ac18 Add comments explaining the role of the bigcomp function in dtoa.c. 2010-01-13 18:21:53 +00:00

Mark Dickinson 8efef5ce9f Issue #7632: Fix a problem with _Py_dg_strtod that could lead to 
crashes in debug builds, for certain long numeric strings
corresponding to subnormal values.

Mark Dickinson 5a0b399aa9 Remove unused BCinfo fields and an unused macro. 2010-01-10 13:06:31 +00:00
Brett Cannon 6fdd3dcb6a DeprecationWarning is now silent by default. 
This was originally suggested by Guido, discussed on the stdlib-sig mailing
list, and given the OK by Guido directly to me. What this change essentially
means is that Python has taken a policy of silencing warnings that are only
of interest to developers by default. This should prevent users from seeing
warnings which are triggered by an application being run against a new
interpreter before the app developer has a chance to update their code.

Closes issue #7319. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin
for helping with the issue.

Mark Dickinson 1b34d2552c Issue #5080: turn the DeprecationWarning from float arguments passed 
to integer PyArg_Parse* format codes into a TypeError.  Add a
DeprecationWarning for floats passed with the 'L' format code, which
didn't previously have a warning.

Benjamin Peterson 0f02d3933b check if the attribute is set before deleting it with T_OBJECT_EX (fixes #7604) 
Also, add a note to the docs about the better behavior of T_OBJECT_EX as
compared to T_OBJECT.

Georg Brandl 740cdc3a9f #7033: add new API function PyErr_NewExceptionWithDoc, for easily giving new exceptions a docstring. 2009-12-28 08:34:58 +00:00

Mark Dickinson 3dc254181a Issue #6985: number of range() items should be constrained to lie 
in a Py_ssize_t, not an int.

Mark Dickinson 34398184eb Issue #7406: Fix some occurrences of potential signed overflow in int 
arithmetic.

Mark Dickinson ccc690d650 Issue #1678380: When distinguishing between -0.0 and 0.0 in 
compiler_add_o, use copysign instead of examining the first and last
bytes of the double.  The latter method fails for little-endian
ARM, OABI, where doubles are little-endian but with the words swapped.

Benjamin Peterson 99a5023c80 improve several corner cases related with argument names in parenthesis 
- Fix #7362: give a good error message for parenthesized arguments with
  defaults.

- Add a py3k warning for any parenthesized arguments since those are not allowed
  in Py3.  This warning is not given in tuple unpacking, since that incurs the
  tuple unpacking warning.

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.

Mark Dickinson 51ae4921b3 Set retval on PyOS_string_to_double failure. 2009-10-31 12:47:47 +00:00
Mark Dickinson 504a151c82 Issue #6603: Fix --with-tsc build failures on x86-64 that resulted 
from a gcc inline assembler peculiarity. (gcc's "A" constraint
apparently means 'rax or rdx' in 64-bit mode, not edx:eax
or rdx:rax as one might expect.)

Mark Dickinson 09823a2e21 Deprecate PyOS_ascii_strtod and PyOS_ascii_atof, and document the replacement function PyOS_string_to_double. 2009-10-31 09:42:39 +00:00
Benjamin Peterson ea0e3b0d60 do a backport of r75928 
The added test does not fail without the patch, but we still fix the issue of
surrogates being used in wide builds where they should not be.

Eric Smith b218d289e6 Removed PyOS_ascii_atof from marshal.c, as mentioned in issue 7117. Also brings it more in line with py3k. 2009-10-27 19:42:57 +00:00
