Victor Stinner 3a50e7056e Issue #12281: Rewrite the MBCS codec to handle correctly replace and ignore 
error handlers on all Windows versions. The MBCS codec is now supporting all
error handlers, instead of only replace to encode and ignore to decode.

Antoine Pitrou dd4e2f0153 Issue #13155: Optimize finding the optimal character width of an unicode string 2011-10-13 00:02:27 +02:00
Victor Stinner 49a0a21f37 Unicode replace() avoids calling unicode_adjust_maxchar() when it's useless 
Add also a special case if the result is an empty string.

Victor Stinner 983b1434bd Backed out changeset 952d91a7d376 
If maxchar == PyUnicode_MAX_CHAR_VALUE(unicode), we do an useless copy.

Antoine Pitrou 53bb548f22 Avoid exporting private helpers 
(thanks "make smelly")
 2011-10-10 23:49:24 +02:00
Victor Stinner 794d567b17 any_find_slice() doesn't use callbacks anymore 
* Call directly the right find/rfind method: allow inlining functions
 * Remove Py_LOCAL_CALLBACK (added for any_find_slice)
 2011-10-10 03:21:36 +02:00
Martin v. Löwis afe55bba33 Add API for static strings, primarily good for identifiers.

Victor Stinner 25a4b29c95 str.replace() avoids memory when it's possible 2011-10-06 12:31:55 +02:00
Victor Stinner 56c161ab00 _copy_characters() fails more quickly in debug mode on inconsistent state 2011-10-06 02:47:11 +02:00
Victor Stinner c729b8e92f Fix a compiler warning: don't define unicode_is_singleton() in release mode 2011-10-06 02:36:59 +02:00
Victor Stinner fb9ea8c57e Don't check for the maximum character when copying from unicodeobject.c 
* Create copy_characters() function which doesn't check for the maximum
   character in release mode
 * _PyUnicode_CheckConsistency() is no more static to be able to use it
   in _PyUnicode_FormatAdvanced() (in formatter_unicode.c)
 * _PyUnicode_CheckConsistency() checks the string hash
 2011-10-06 01:45:57 +02:00
Victor Stinner 05d1189566 Fix post-condition in unicode_repr(): check the result, not the input 2011-10-06 01:13:58 +02:00
Victor Stinner f48323e3b3 replace() uses unicode_fromascii() if the input and replace string is ASCII 2011-10-05 23:27:08 +02:00
Victor Stinner 0617b6e18b unicode_fromascii() checks that the input is ASCII in debug mode 2011-10-05 23:26:01 +02:00
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.

Victor Stinner 14f8f02826 Fix PyUnicode_Partition(): str_in->str_obj 2011-10-05 20:58:25 +02:00
Victor Stinner bb10a1f759 Ensure that newly created strings use the most efficient store in debug mode 2011-10-05 01:34:17 +02:00
Victor Stinner 9310abbf40 Replace PyUnicodeObject* with PyObject* where it was inappropriate 2011-10-05 00:59:23 +02:00
Victor Stinner ce5faf673e unicodeobject.c doesn't make output strings ready in debug mode 
Try to only create non ready strings in debug mode to ensure that all functions
(not only in unicodeobject.c, everywhere) make input strings ready.

Georg Brandl 7597addbd4 More typoes. 2011-10-05 16:36:47 +02:00
Victor Stinner c80d6d20d5 Speedup str[a🅱️step] for step != 1 
Try to stop the scanner of the maximum character before the end using a limit
depending on the kind (e.g. 256 for PyUnicode_2BYTE_KIND).
 2011-10-05 14:13:28 +02:00
Victor Stinner ae86485517 Speedup find_maxchar_surrogates() for 32-bit wchar_t 
If we have at least one character in U+10000-U+10FFFF, we know that we must use
PyUnicode_4BYTE_KIND kind.
 2011-10-05 14:02:44 +02:00
Victor Stinner b9275c104e Speedup str[a:b] and PyUnicode_FromKindAndData 
* str[a:b] doesn't scan the string for the maximum character if the string
   is ascii only
 * PyUnicode_FromKindAndData() stops if we are sure that we cannot use a
   shorter character type. For example, _PyUnicode_FromUCS1() stops if we
   have at least one character in range U+0080-U+00FF

Victor Stinner 702c734395 Speedup the ASCII decoder 
It is faster for long string and a little bit faster for short strings,
benchmark on Linux 32 bits, Intel Core i5 @ 3.33GHz:

./python -m timeit 'x=b"a"' 'x.decode("ascii")'
./python -m timeit 'x=b"x"*80' 'x.decode("ascii")'
./python -m timeit 'x=b"abc"*4096' 'x.decode("ascii")'
