Mark Dickinson adcda3400f Issue #7743: Fix a potential incorrect rounding bug in dtoa.c (2nd bug
in issue 7743).

Mark Dickinson ca6ea56718 Additional explanatory comments for _Py_dg_strtod. 2010-01-20 21:23:25 +00:00
Mark Dickinson 1942806013 Don't try to put a value into a NULL pointer. 2010-01-20 18:02:41 +00:00
Mark Dickinson 4141d65fb7 Various dtoa.c cleanups. 1. Despagghetify _Py_dg_strtod parsing code
and exit points.  2. Simplify bigcomp comparison loop.  3. Don't set
ERANGE on _Py_dg_strtod underflow (it was set inconsistently anyway).
4. Remove unused dsign field from BCinfo struct.

Mark Dickinson 9481c576cd Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the
private memory allocation scheme in dtoa.c, along with a piece of code
that caches powers of 5 for future use.  This makes it easier to
detect dtoa.c memory leaks with Valgrind or similar tools.

Patch by Stefan Krah.

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).

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 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

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.

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.
