Serhiy Storchaka	58cf607d13	Issue #12892 : The utf-16* and utf-32* codecs now reject (lone) surrogates. The utf-16* and utf-32* encoders no longer allow surrogate code points (U+D800-U+DFFF) to be encoded. The utf-32* decoders no longer decode byte sequences that correspond to surrogate code points. The surrogatepass error handler now works with the utf-16* and utf-32* codecs. Based on patches by Victor Stinner and Kang-Hao (Kenny) Lu.	12 years ago
Ezio Melotti	745d54d2fa	#17806 : Added keyword-argument support for "tabsize" to str/bytes.expandtabs().	12 years ago
Victor Stinner	cc64eb5b9f	Issue #18408 : Fix bytearrayiter.partition()/rpartition(), handle PyByteArray_FromStringAndSize() failure (ex: on memory allocation failure)	12 years ago
Serhiy Storchaka	8fa8ee3970	Issue #18701 : Remove support of old CPython versions (<3.0) from C code.	13 years ago
Raymond Hettinger	b1b915c796	Issue 18719: Remove a false optimization Remove an unused early-out test from the critical path for dict and set lookups. When the strings already have matching lengths, kinds, and hashes, there is no additional information gained by checking the first characters (the probability of a mismatch is already known to be less than 1 in 2**64).	13 years ago
Antoine Pitrou	9ed5f27266	Issue #18722 : Remove uses of the "register" keyword in C code.	13 years ago
Benjamin Peterson	d2b58a9880	only recursively expand in the format spec (closes #17644 )	13 years ago
Benjamin Peterson	4d94474ba3	rewrite the parsing of field names to be more consistent wrt recursive expansion	13 years ago
Ezio Melotti	6b02772c13	Remove trailing whitespace.	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
Victor Stinner	76b3b2726c	stringlib: remove unused STRINGLIB_RESIZE macro	13 years ago
Serhiy Storchaka	e2cef885a2	Issue #16061 : Speed up str.replace() for replacing 1-character strings.	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	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
Serhiy Storchaka	18809fa94e	Remove unused defines.	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
Serhiy Storchaka	18ba40b945	Check for NULL before the pointer aligning in fastsearch_memchr_1char. There is no guarantee that NULL is aligned.	13 years ago
Christian Heimes	5f7e8dab11	Issue #16592 : stringlib_bytes_join doesn't raise MemoryError on allocation failure	13 years ago
Victor Stinner	ab60de478d	Issue #8271 : Fix compilation on Windows	13 years ago

Mark Dickinson	fb90c0934c	Issue #14700 : Fix buggy overflow checks for large precision and width in new-style and old-style formatting.	13 years ago
Mark Dickinson	75d3600466	Issue #14700 : Fix buggy overflow checks for large precision and width in new-style and old-style formatting.	13 years ago

Victor Stinner	b3f5501250	Close #15534 : Fix a typo in the fast search function of the string library (_s => s) Replace _s with ptr to avoid future confusion. Add also non regression tests.	14 years ago

Victor Stinner	d7b7c7472b	Issue #14993 : Use standard "unsigned char" instead of a unsigned char bitfield	14 years ago
Victor Stinner	d3f0882dfb	Issue #14744 : Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args) * Formatting string, int, float and complex use the _PyUnicodeWriter API. It avoids a temporary buffer in most cases. * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just keep a reference to the string if the output is only composed of one string * Disable overallocation when formatting the last argument of str%args and str.format(args) * Overallocation allocates at least 100 characters: add min_length attribute to the _PyUnicodeWriter structure * Add new private functions: _PyUnicode_FastCopyCharacters(), _PyUnicode_FastFill() and _PyUnicode_FromASCII() The speed up is around 20% in average.	14 years ago
Antoine Pitrou	63065d761e	Issue #14624 : UTF-16 decoding is now 3x to 4x faster on various inputs. Patch by Serhiy Storchaka.	14 years ago

Victor Stinner	ee4544c920	Issue #14744 : Inline unicode_writer_write_char() and unicode_write_str() Optimize also PyUnicode_Format(): call unicode_writer_prepare() only once per argument.	14 years ago
Victor Stinner	202fdca133	Close #14716 : str.format() now uses the new "unicode writer" API instead of the PyAccu API. For example, it makes str.format() from 25% to 30% faster on Linux.	14 years ago
Victor Stinner	41a863cb81	Issue #13706 : Fix format(int, "n") for locale with non-ASCII thousands separator * Decode thousands separator and decimal point using PyUnicode_DecodeLocale() (from the locale encoding), instead of decoding them implicitly from latin1 * Remove _PyUnicode_InsertThousandsGroupingLocale(), it was not used * Change _PyUnicode_InsertThousandsGrouping() API to return the maximum character if unicode is NULL * Replace MIN/MAX macros by Py_MIN/Py_MAX * stringlib/undef.h undefines STRINGLIB_IS_UNICODE * stringlib/localeutil.h only supports Unicode	14 years ago

Antoine Pitrou	0a3229de6b	Issue #13417 : speed up utf-8 decoding by around 2x for the non-fully-ASCII case. This almost catches up with pre-PEP 393 performance, when decoding needed only one pass.	14 years ago
Victor Stinner	0fc35196bb	stringlib: remove unused STRINGLIB_FILL	14 years ago
Victor Stinner	7931d9a951	Replace PyUnicodeObject type by PyObject * _PyUnicode_CheckConsistency() now takes a PyObject* instead of void* * Remove now useless casts to PyObject*	14 years ago
Victor Stinner	9db1a8b69f	Replace PyUnicodeObject* by PyObject* where it was irrevelant A Unicode string can now be a PyASCIIObject, PyCompactUnicodeObject or PyUnicodeObject. Aliasing a PyASCIIObject* or PyCompactUnicodeObject* to PyUnicodeObject* is wrong	14 years ago
Antoine Pitrou	ac65d96777	Issue #12170 : The count(), find(), rfind(), index() and rindex() methods of bytes and bytearray objects now accept an integer between 0 and 255 as their first argument. Patch by Petri Lehtinen.	14 years ago
Antoine Pitrou	5b9f4c1539	Fix typo	14 years ago
