Victor Stinner ee4544c920 Issue #14744: Inline unicode_writer_write_char() and unicode_write_str()

per argument.

Victor Stinner 106802547c Backout ab500b297900: the check for integer overflow is wrong

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.

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. 2012-05-07 11:20:50 +01:00
Victor Stinner d0dba6eee8 unicode_writer: don't force inline when it is not necessary 
Keep inline for performance critical functions (functions used in loops)

Benjamin Peterson b63f49f2b4 if the kind of the string to count is larger than the string to search, shortcut to 0 2012-05-03 18:31:07 -04:00
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"
 2012-05-03 23:58:55 +02:00
Victor Stinner bf4e266397 Issue #14687: Remove redundant length attribute of unicode_write_t

Victor Stinner 7989157e49 Issue #14687: Cleanup unicode_writer_prepare() 
"Inline" PyUnicode_Resize(): call directly resize_compact()
 2012-05-03 13:43:07 +02:00
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.

Victor Stinner 1b487b467b Issue #14624, #14687: Optimize unicode_widen()

 2012-05-03 12:29:04 +02:00
Victor Stinner 3a7f7977f1 Remove buggy assertion in PyUnicode_Substring()

 2012-05-03 03:36:40 +02:00
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.

Victor Stinner bff7c96834 Issue #14687: Optimize str%tuple for the "%(name)s" syntax 
Avoid an useless and expensive call to PyUnicode_READ().
 2012-05-03 01:44:59 +02:00
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)

Victor Stinner 438106b66e Issue #14687: Cleanup PyUnicode_Format() 2012-05-02 00:41:57 +02:00
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)

Victor Stinner b11d91d969 Fix my previous commit: bool is a long, restore the specical case for bool 2012-04-28 00:25:34 +02:00
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()

Victor Stinner 94d558b063 Optimize _PyUnicode_FindMaxChar() find pure ASCII strings 2012-04-27 22:26:58 +02:00
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()
