4c38154a43 Don't parenthesis in _PyObject_CallMethodId() format 
Issue #28915: Without parenthesis, _PyObject_CallMethodId() avoids the creation
a temporary tuple, and so is more efficient.

3b73ea1278 Issue #28701: Replace PyUnicode_CompareWithASCIIString with _PyUnicode_EqualToASCIIString. 
The latter function is more readable, faster and doesn't raise exceptions.

45059eb1d0 1) Prepare libmpdec for the 2.4.0 release. None of the following changes affects 
_decimal:

      o Make all "mpd_t to C integer" conversion functions available in both the
        64-bit and the 32-bit versions.

      o Make all mixed mpd_t/C integer arithmetic functions available in the
        32-bit version.

      o Better handling of __STDC_LIMIT_MACROS for C++ users.

      o Add struct tags (at the request of C++ users).

2) Check for libmpdec.so.2 if --with-system-libmpdec is used.

eb8c451bd2 Since the return type of format() is not a Decimal, raise ValueError instead of 
InvalidOperation if the format specification (width, prec) exceeds the internal

ad5b43995e In the 32-bit build, dec_hash() raised InvalidOperation if the operand 
had a coefficient with MAX_PREC=425000000 digits and a negative exponent.
Increasing the context limits above the official values fixes the issue
and is safe (in this case!).

b9e36b97f2 Add unused parameter to a couple of METH_NOARGS functions. The previous 
form is used in many places in the source tree, but was found to be incorrect
in a recent tracker discussion.

c35a8e5c98 Proactive reliability fix for broken FPUs: The base conversion functions 
use log10() to calculate the size of the output array. The current code
has been tested on x86/amd64 (and to a lesser extent on qemu-mips qemu-sparc)
and produces sufficiently large values for all inputs tested so far (coefficient
sizes of 10**18 - 1 are hard to test exhaustively).

The new code does not rely on the correctness of log10() and resizes
the output arrays if the allocated space is insufficient.

78f075636c Speed up _decimal by another 10-15% by caching the thread local context 
that was last accessed. In the pi benchmark (64-bit platform, prec=9),
_decimal is now only 1.5x slower than float.
