Victor Stinner	a0dd0213cc	Close #17693 : Rewrite CJK decoders to use the _PyUnicodeWriter API instead of the legacy Py_UNICODE API. Add also a new _PyUnicodeWriter_WriteChar() function.	13 years ago
Antoine Pitrou	36b045f4db	Fix supernumerary 's' in sys._debugmallocstats() output.	13 years ago
Benjamin Peterson	c9314d9e08	don't run frame if it has no stack (closes #17669 )	13 years ago
Victor Stinner	247109e74d	Issue #17615 : On Windows (VS2010), Performances of wmemcmp() to compare Unicode strings are not convincing. For UCS2 (16-bit wchar_t type), use a dummy loop instead of wmemcmp(). The dummy loop is as fast, or a little bit faster. wchar_t is only 16-bit long on Windows. wmemcmp() is still used for 32-bit wchar_t.	13 years ago
Victor Stinner	0cff4b16d9	replace(): only call PyUnicode_DATA(u) once	13 years ago
Victor Stinner	cc7af72192	Write super-fast version of str.strip(), str.lstrip() and str.rstrip() for pure ASCII	13 years ago
Victor Stinner	f50a4e9bc9	Don't calls macros in PyUnicode_WRITE() parameters PyUnicode_WRITE() expands some parameters twice or more.	13 years ago
Victor Stinner	9c79e41fc5	Fix do_strip(): don't call PyUnicode_READ() in Py_UNICODE_ISSPACE() to not call it twice	13 years ago
Victor Stinner	b3a6014504	Fix _PyUnicode_XStrip() Inline the BLOOM_MEMBER() to only call PyUnicode_READ() only once (per loop iteration). Store also the length of the seperator in a variable to avoid calls to PyUnicode_GET_LENGTH().	13 years ago
Victor Stinner	63d5c1a14a	Optimize PyUnicode_DecodeCharmap() Avoid expensive PyUnicode_READ() and PyUnicode_WRITE(), manipulate pointers instead.	13 years ago
Victor Stinner	a85af502a4	Optimize make_bloom_mask(), used by str.strip(), str.lstrip() and str.rstrip() Write specialized functions per Unicode kind to avoid the expensive PyUnicode_READ() macro.	13 years ago
Victor Stinner	69ed0f4c86	Use PyUnicode_READ() instead of PyUnicode_READ_CHAR() "PyUnicode_READ_CHAR() is less efficient than PyUnicode_READ() because it calls PyUnicode_KIND() and might call it twice." according to its documentation.	13 years ago
Victor Stinner	03c3e35d42	Add fast-path in PyUnicode_DecodeCharmap() for pure 8 bit encodings: cp037, cp500 and iso8859_1 codecs	13 years ago
Victor Stinner	cd777eaf53	Issue #17615 : Comparing two Unicode strings now uses wmemcmp() when possible wmemcmp() is twice faster than a dummy loop (342 usec vs 744 usec) on Fedora 18/x86_64, GCC 4.7.2.	13 years ago
Victor Stinner	c1302bba4c	Issue #17615 : Expand expensive PyUnicode_READ() macro in unicode_compare(): write specialized functions for each combination of Unicode kinds.	13 years ago
Victor Stinner	7efa3b8242	Close #13126 : "Simplify" FASTSEARCH() code to help the compiler to emit more efficient machine code. Patch written by Antoine Pitrou. Without this change, str.find() was 10% slower than str.rfind() in the worst case.	13 years ago

Victor Stinner	eb4b5ac8af	Close #16757 : Avoid calling the expensive _PyUnicode_FindMaxChar() function when possible	13 years ago
Victor Stinner	cfc4c13b04	Add _PyUnicodeWriter_WriteSubstring() function Write a function to enable more optimizations: * If the substring is the whole string and overallocation is disabled, just keep a reference to the string, don't copy characters * Avoid a call to the expensive _PyUnicode_FindMaxChar() function when possible	13 years ago
Benjamin Peterson	6395241471	list slotdefs in offset order rather than sorting them (closes #17610 ) This means we can remove our usage of qsort() than relied on undefined behavior.	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
