Victor Stinner	ce179bf6ba	Add _PyBytesWriter_WriteBytes() to factorize the code	10 years ago
Victor Stinner	ad7715891e	_PyBytesWriter: simplify code to avoid "prealloc" parameters Substract preallocate bytes from min_size before calling _PyBytesWriter_Prepare().	10 years ago
Victor Stinner	e7bf86cd7d	Optimize backslashreplace error handler Issue #25318: Optimize backslashreplace and xmlcharrefreplace error handlers in UTF-8 encoder. Optimize also backslashreplace error handler for ASCII and Latin1 encoders. Use the new _PyBytesWriter API to optimize these error handlers for the encoders. It avoids to create an exception and call the slow implementation of the error handler.	10 years ago
Victor Stinner	fdfbf78114	Issue #25318 : Add _PyBytesWriter API Add a new private API to optimize Unicode encoders. It uses a small buffer allocated on the stack and supports overallocation. Use _PyBytesWriter API for UCS1 (ASCII and Latin1) and UTF-8 encoders. Enable overallocation for the UTF-8 encoder with error handlers. unicode_encode_ucs1(): initialize collend to collstart+1 to not check the current character twice, we already know that it is not ASCII.	10 years ago
Victor Stinner	01ada3996b	Issue #25267 : The UTF-8 encoder is now up to 75 times as fast for error handlers: ``ignore``, ``replace``, ``surrogateescape``, ``surrogatepass``. Patch co-written with Serhiy Storchaka.	10 years ago
Eric V. Smith	ab2aa6dc91	Fixed an incorrect comment.	11 years ago
Serhiy Storchaka	7e29eea926	Fixed typos in comments.	11 years ago

Serhiy Storchaka	d9d769fcdd	Issue #23573 : Increased performance of string search operations (str.find, str.index, str.count, the in operator, str.split, str.partition) with arguments of different kinds (UCS1, UCS2, UCS4).	11 years ago
Serhiy Storchaka	009b811d67	Removed unintentional trailing spaces in non-external and non-generated C files.	11 years ago

Serhiy Storchaka	b757c83ec6	Issue #22581 : Use more "bytes-like object" throughout the docs and comments.	11 years ago
Benjamin Peterson	1cc9520327	s/stringobject/bytesobject/ (closes #22036 ) Patch by Martin Matusiak.	12 years ago
Benjamin Peterson	23cf403ca1	fix expandtabs overflow detection to be consistent and not rely on signed overflow	12 years ago

Benjamin Peterson	0ee22bf774	fix format spec recursive expansion (closes #19729 )	12 years ago
Serhiy Storchaka	dc2fd5101a	Remove dead code committed in issue #12892 .	12 years ago
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
