Kristjan Valur Jonsson	85634d7a2e	Issue #14909 : A number of places were using PyMem_Realloc() apis and PyObject_GC_Resize() with incorrect error handling. In case of errors, the original object would be leaked. This checkin fixes those cases.	14 years ago
Victor Stinner	3a7d096f2f	Issue #14744 : Fix compilation on Windows (part 2)	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

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	f59c28c930	unicode_writer_finish() checks string consistency	14 years ago
Victor Stinner	106802547c	Backout ab500b297900: the check for integer overflow is wrong Issue #14716: Change integer overflow check in unicode_writer_prepare() to compute the limit at compile time instead of runtime. Patch writen by Serhiy Storchaka.	14 years ago
Victor Stinner	0576f9b4cf	Issue #14716 : Change integer overflow check in unicode_writer_prepare() to compute the limit at compile time instead of runtime. Patch writen by Serhiy Storchaka.	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
Mark Dickinson	99e2e5552a	Issue #14700 : Fix two broken and undefined-behaviour-inducing overflow checks in old-style string formatting. Thanks Serhiy Storchaka for report and original patch.	14 years ago
Victor Stinner	d0dba6eee8	unicode_writer: don't force inline when it is not necessary Keep inline for performance critical functions (functions used in loops)	14 years ago
Benjamin Peterson	b63f49f2b4	if the kind of the string to count is larger than the string to search, shortcut to 0	14 years ago
Victor Stinner	a7b654be30	unicode_writer: add finish() method and assertions to write_str() method * The write_str() method does nothing if the length is zero. * Replace "struct unicode_writer_t" with "unicode_writer_t"	14 years ago

Victor Stinner	7989157e49	Issue #14687 : Cleanup unicode_writer_prepare() "Inline" PyUnicode_Resize(): call directly resize_compact()	14 years ago
Victor Stinner	f2c76aa6cb	Issue #14687 : str%tuple now uses an optimistic "unicode writer" instead of an accumulator. Directly write characters into the output (don't use a temporary list): resize and widen the string on demand.	14 years ago
Victor Stinner	1b487b467b	Issue #14624 , #14687 : Optimize unicode_widen() Don't convert uninitialized characters. Patch written by Serhiy Storchaka.	14 years ago
Victor Stinner	3a7f7977f1	Remove buggy assertion in PyUnicode_Substring() Use also directly unicode_empty, instead of PyUnicode_New(0,0).	14 years ago
Victor Stinner	684d5fd420	Fix PyUnicode_Substring() for start >= length and start > end Remove the fast-path for 1-character string: unicode_fromascii() and _PyUnicode_FromUCS*() now have their own fast-path for 1-character strings.	14 years ago
Victor Stinner	b6cd014d75	Unicode: optimize creating of 1-character strings	14 years ago
Victor Stinner	bff7c96834	Issue #14687 : Optimize str%tuple for the "%(name)s" syntax Avoid an useless and expensive call to PyUnicode_READ().	14 years ago
Victor Stinner	e6abb488c9	unicodeobject.c: Add MAX_MAXCHAR() macro to (micro-)optimize the computation of the second argument of PyUnicode_New(). * Create also align_maxchar() function * Optimize fix_decimal_and_space_to_ascii(): don't compute the maximum character when ch <= 127 (it is ASCII)	14 years ago
Victor Stinner	438106b66e	Issue #14687 : Cleanup PyUnicode_Format()	14 years ago
Victor Stinner	b5c3ea3af3	Issue #14687 : Optimize str%args * formatfloat() uses unicode_fromascii() instead of PyUnicode_DecodeASCII() to not have to check characters, we know that it is really ASCII * Use PyUnicode_FromOrdinal() instead of _PyUnicode_FromUCS4() to format a character: if avoids a call to ucs4lib_find_max_char() to compute the maximum character (whereas we already know it, it is just the character itself)	14 years ago
Victor Stinner	b80e46eca4	Issue #14687 : Avoid an useless duplicated string in PyUnicode_Format()	14 years ago

Victor Stinner	d0880d57b0	Simplify and optimize formatlong() * Remove _PyBytes_FormatLong(): inline it into formatlong() * the input type is always a long, so remove the code for bool * don't duplicate the string if the length does not change * Use PyUnicode_DATA() instead of _PyUnicode_AsString()	14 years ago
Victor Stinner	94d558b063	Optimize _PyUnicode_FindMaxChar() find pure ASCII strings	14 years ago
Victor Stinner	8f825060f1	Check newly created consistency using _PyUnicode_CheckConsistency(str, 1) * In debug mode, fill the string data with invalid characters * Simplify also reference counting in PyCodec_BackslashReplaceErrors() and PyCodec_XMLCharRefReplaceError()	14 years ago
