* | Issues #26289 and #26315: Optimize floor/modulo div for single-digit longsYury Selivanov2016-02-111-0/+79

Built-in 'divmod' function is now also ~10% faster. -m timeit -s "x=22331" "x//2;x//-3;x//4;x//5;x//-6;x//7;x//8;x//-99;x//100;" with patch: 0.321 without patch: 0.633 -m timeit -s "x=22331" "x%2;x%3;x%-4;x%5;x%6;x%-7;x%8;x%99;x%-100;" with patch: 0.224 without patch: 0.66 Big thanks to Serhiy Storchaka, Mark Dickinson and Victor Stinner for thorow code reviews and algorithms improvements.

* | | Issue #25349: Optimize bytes % intVictor Stinner2015-10-091-27/+93
|/ / | | | | | | | | | | | | | | Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X. _PyBytesWriter is now used to format directly the integer into the writer buffer, instead of using a temporary bytes object. Formatting is between 30% and 50% faster on a microbenchmark.
* | Issue #24999: In longobject.c, use two shifts instead of ">> 2*PyLong_SHIFT" toVictor Stinner2015-09-191-4/+6
| | | | | | | | | | | | avoid undefined behaviour when LONG_MAX type is smaller than 60 bits. This change should fix a warning with the ICC compiler.
* | Issue #22486: Added the math.gcd() function. The fractions.gcd() function ↵Serhiy Storchaka2015-05-121-0/+205

* | #16518: Bring error messages in harmony with docs ("bytes-like object")R David Murray2014-10-051-3/+1
| | | | | | | | | | | | | | | | | | | | Some time ago we changed the docs to consistently use the term 'bytes-like object' in all the contexts where bytes, bytearray, memoryview, etc are used. This patch (by Ezio Melotti) completes that work by changing the error messages that previously reported that certain types did "not support the buffer interface" to instead say that a bytes-like object is required. (The glossary entry for bytes-like object references the discussion of the buffer protocol in the docs.)
* | Removed redundant casts to `char *`.Serhiy Storchaka2014-09-281-1/+1
| | | | | | | | Corresponding functions now accept `const char *` (issue #1772673).
* | Issue #22156: Fix "comparison between signed and unsigned integers" compilerVictor Stinner2014-08-151-2/+2
| | | | | | | | | | | | | | warnings in the Objects/ subdirectory. PyType_FromSpecWithBases() and PyType_FromSpec() now reject explicitly negative slot identifiers.

* | Issue #19171: speed some cases of 3-argument long pow().Tim Peters2013-10-051-4/+10
|\ \ | |/ | | | | | | | | | | | | | | | | Reduce the base by the modulus when the base is larger than the modulus. This can unboundedly speed the "startup costs" of doing modular exponentiation, particularly in cases where the base is much larger than the modulus. Original patch by Armin Rigo, inspired by https://github.com/pyca/ed25519. Merged from 3.3.
