Victor Stinner	f963c13597	longobject.c: fix compilation warning on Windows 64-bit We know that Py_SIZE(b) is -1 or 1 an so fits into the sdigit type.	10 years ago
Yury Selivanov	e0b23095ee	Issues #26289 and #26315 : Optimize floor/modulo div for single-digit longs Microbenchmarks show 2-2.5x improvement. 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.	10 years ago

Serhiy Storchaka	15095800a3	Issue #24731 : Fixed crash on converting objects with special methods __bytes__, __trunc__, and __float__ returning instances of subclasses of bytes, int, and float to subclasses of bytes, int, and float correspondingly.	10 years ago
Victor Stinner	1285e5c805	Fix compiler warnings (uninitialized variables), false alarms in fact	10 years ago
Victor Stinner	199c9a6f4b	Fix long_format_binary() Issue #25399: Fix long_format_binary(), allocate bytes for the bytes writer.	10 years ago
Victor Stinner	be75b8cf23	Issue #25349 : Optimize bytes % int 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.	10 years ago
Victor Stinner	5783fd2c58	Issue #24999 : In longobject.c, use two shifts instead of ">> 2*PyLong_SHIFT" to avoid undefined behaviour when LONG_MAX type is smaller than 60 bits. This change should fix a warning with the ICC compiler.	10 years ago
Serhiy Storchaka	48e47aaa28	Issue #22486 : Added the math.gcd() function. The fractions.gcd() function now is deprecated. Based on patch by Mark Dickinson.	11 years ago
R David Murray	861470c836	#16518 : Bring error messages in harmony with docs ("bytes-like object") 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.)	11 years ago
Serhiy Storchaka	20b39b27d9	Removed redundant casts to `char `. Corresponding functions now accept `const char ` (issue #1772673).	11 years ago
Victor Stinner	12174a5dca	Issue #22156 : Fix "comparison between signed and unsigned integers" compiler warnings in the Objects/ subdirectory. PyType_FromSpecWithBases() and PyType_FromSpec() now reject explicitly negative slot identifiers.	12 years ago
Victor Stinner	45e8e2f218	Issue #21490 : Add new C macros: Py_ABS() and Py_STRINGIFY() Keep _Py_STRINGIZE() in PC/pyconfig.h to not introduce a dependency between pyconfig.h and pymacros.h.	12 years ago
Mark Dickinson	0c346d827d	Issue #21193 : Make (e.g.,) pow(2, -3, 5) raise ValueError rather than TypeError. Patch by Josh Rosenberg.	12 years ago

Serhiy Storchaka	31a655411a	Issue #17576 : Deprecation warning emitted now when __int__() or __index__() return not int instance. Introduced _PyLong_FromNbInt() and refactored PyLong_As*() functions.	12 years ago
Christian Heimes	d3afe781b1	Silence expression result unused warnings with clang. The PyObject_INIT() macros returns obj: ../cpython/Objects/methodobject.c:32:23: warning: expression result unused [-Wunused-value] PyObject_INIT(op, &PyCFunction_Type); ^~ ../cpython/Include/objimpl.h:139:69: note: expanded from macro 'PyObject_INIT' ( Py_TYPE(op) = (typeobj), _Py_NewReference((PyObject *)(op)), (op) ) ^ 1 warning generated.	12 years ago
Serhiy Storchaka	c679227e31	Issue #1772673 : The type of `char` arguments now changed to `const char`.	12 years ago
Tim Peters	81a93159d7	Issue #19171 : speed some cases of 3-argument long pow(). 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.	12 years ago

Mark Dickinson	02515f7a3a	Minor consistency fixes for some longobject.c exception messages: - replace 'long int' / 'long' by 'int' - fix capitalization of "Python" in PyLong_AsUnsignedLong - "is too large" -> "too large", for consistency with other messages.	13 years ago
Victor Stinner	1c8f059019	Issue #18520 : Add a new PyStructSequence_InitType2() function, same than PyStructSequence_InitType() except that it has a return value (0 on success, -1 on error). * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure * Fix also some calls to PyDict_SetItemString(): handle error	13 years ago
Victor Stinner	08a80b11ad	longobject.c: add an assertion to ensure that MEDIUM_VALUE() is only called on small integers (0 or 1 digit)	13 years ago

Victor Stinner	640c35ce13	Reuse Py_MIN and Py_MAX macros: remove duplicate MIN/MAX macros multiprocessing.h: remove unused MIN and MAX macros	13 years ago
Victor Stinner	8f674ccd64	Close #17694 : Add minimum length to _PyUnicodeWriter * Add also min_char attribute to _PyUnicodeWriter structure (currently unused) * _PyUnicodeWriter_Init() has no more argument (except the writer itself): min_length and overallocate must be set explicitly * In error handlers, only enable overallocation if the replacement string is longer than 1 character * CJK decoders don't use overallocation anymore * Set min_length, instead of preallocating memory using _PyUnicodeWriter_Prepare(), in many decoders * _PyUnicode_DecodeUnicodeInternal() checks for integer overflow	13 years ago
Antoine Pitrou	4de7457009	Issue #17173 : Remove uses of locale-dependent C functions (isalpha() etc.) in the interpreter. I've left a couple of them in: zlib (third-party lib), getaddrinfo.c (doesn't include Python.h, and probably obsolete), _sre.c (legitimate use for the re.LOCALE flag).	13 years ago

Chris Jerdonek	83fe2e1c22	Issue #14783 : Improve int() docstring and also str(), range(), and slice(). This commit rewrites the docstring for int() to incorporate the documentation changes made in issue #16036. It also switches the docstrings for int(), str(), range(), and slice() to use multi-line signatures.	13 years ago
