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
Antoine Pitrou	ca5f91b888	Issue #14738 : Speed-up UTF-8 decoding on non-ASCII data. Patch by Serhiy Storchaka.	14 years ago
Victor Stinner	3b1a74a9c3	Rename unicode_write_t structure and its methods to "_PyUnicodeWriter"	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
Benjamin Peterson	21e0da228d	remove some usage of Py_UNICODE_TOUPPER/LOWER	14 years ago
Victor Stinner	6099a03202	Issue #13624 : Write a specialized UTF-8 encoder to allow more optimization The main bottleneck was the PyUnicode_READ() macro.	14 years ago
Victor Stinner	f8eac00779	Issue #13623 : Fix a performance regression introduced by issue #12170 in bytes.find() and handle correctly OverflowError (raise the same ValueError than the error for -1).	14 years ago
Victor Stinner	b37b17423b	Replace PyUnicode_FromUnicode(NULL, 0) by PyUnicode_New(0, 0) Create an empty string with the new Unicode API.	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

Martin v. Löwis	c47adb04b3	Change PyUnicode_KIND to 1,2,4. Drop _KIND_SIZE and _CHARACTER_SIZE.	14 years ago
Antoine Pitrou	4574e62c6e	Fix massive slowdown in string formatting with str.format. Example: ./python -m timeit -s "f='{}' + '-' * 1024 + '{}'; s='abcd' * 16384" "f.format(s, s)" -> before: 547 usec per loop -> after: 13 usec per loop -> 3.2: 22.5 usec per loop -> 2.7: 12.6 usec per loop	14 years ago
Antoine Pitrou	dbf697ae5c	Fix compilation warnings under 64-bit Windows	14 years ago
Victor Stinner	c3cec7868b	Add asciilib: similar to ucs1, ucs2 and ucs4 library, but specialized to ASCII ucs1, ucs2 and ucs4 libraries have to scan created substring to find the maximum character, whereas it is not need to ASCII strings. Because ASCII strings are common, it is useful to optimize ASCII.	14 years ago

Eric Smith	984bb58000	Issue #7094 : Add alternate ('#') flag to __format__ methods for float, complex and Decimal. Allows greater control over when decimal points appear. Added to make transitioning from %-formatting easier. '#g' still has a problem with Decimal which I'll fix soon.	15 years ago
