Ezio Melotti 5263c13801 Merge removal of trailing whitespace from 3.3. 2013-04-21 04:08:18 +03:00
Ezio Melotti 6b02772c13 Remove trailing whitespace. 2013-04-21 04:07:51 +03:00
Victor Stinner bb4503f61e Partial revert of changeset 9744b2df134c 
PyUnicode_Append() cannot call directly resize_compact(): I forgot that a
string can be ready *and* not compact (a legacy string can also be ready).

Victor Stinner fb161b1b6d Split PyUnicode_DecodeCharmap() into subfunction for readability 2013-04-18 01:44:27 +02:00

Victor Stinner 376cfa122d Fix typo in unicode_decode_call_errorhandler_writer() 
Bug introduced by changeset 7ed9993d53b4.

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
 2013-04-17 23:02:17 +02:00
Victor Stinner 77282cb4f8 Cleanup PyUnicode_Contains() 
* No need to double-check that strings are ready: test already done by
   PyUnicode_FromObject()
 * Remove useless kind variable (use kind1 instead)

Victor Stinner d92e078c8d Minor change: fix character in do_strip() for the ASCII case 2013-04-14 19:17:42 +02:00
Victor Stinner f033510fee Cleanup PyUnicode_Append() 
* Check also that right is a Unicode object
 * call directly resize_compact() instead of unicode_resize() for a more
   explicit error handling, and to avoid testing some properties twice
   (ex: unicode_modifiable())

Benjamin Peterson 34ad84d80a merge 3.3 (#17669) 2013-04-10 17:01:38 -04:00
Benjamin Peterson c9314d9e08 don't run frame if it has no stack (closes #17669) 2013-04-10 17:00:56 -04:00
Victor Stinner 247109e74d Issue #17615: On Windows (VS2010), Performances of wmemcmp() to compare Unicode 
strings are not convincing. For UCS2 (16-bit wchar_t type), use a dummy loop
instead of wmemcmp(). The dummy loop is as fast, or a little bit faster.

wchar_t is only 16-bit long on Windows. wmemcmp() is still used for 32-bit
wchar_t.

Victor Stinner f50a4e9bc9 Don't calls macros in PyUnicode_WRITE() parameters 
PyUnicode_WRITE() expands some parameters twice or more.

Victor Stinner 9c79e41fc5 Fix do_strip(): don't call PyUnicode_READ() in Py_UNICODE_ISSPACE() to not call 
it twice
 2013-04-09 22:21:08 +02:00
Victor Stinner b3a6014504 Fix _PyUnicode_XStrip() 
Inline the BLOOM_MEMBER() to only call PyUnicode_READ() only once (per loop
iteration). Store also the length of the seperator in a variable to avoid calls
to PyUnicode_GET_LENGTH().

Victor Stinner 63d5c1a14a Optimize PyUnicode_DecodeCharmap()

PyUnicode_READ() macro.
 2013-04-09 21:53:54 +02:00
Victor Stinner 69ed0f4c86 Use PyUnicode_READ() instead of PyUnicode_READ_CHAR() 
"PyUnicode_READ_CHAR() is less efficient than PyUnicode_READ() because it calls
PyUnicode_KIND() and might call it twice." according to its documentation.

Victor Stinner 03c3e35d42 Add fast-path in PyUnicode_DecodeCharmap() for pure 8 bit encodings:

Victor Stinner cd777eaf53 Issue #17615: Comparing two Unicode strings now uses wmemcmp() when possible 
wmemcmp() is twice faster than a dummy loop (342 usec vs 744 usec) on Fedora
18/x86_64, GCC 4.7.2.

Victor Stinner c1302bba4c Issue #17615: Expand expensive PyUnicode_READ() macro in unicode_compare():

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.

Victor Stinner eb4b5ac8af Close #16757: Avoid calling the expensive _PyUnicode_FindMaxChar() function 
when possible
 2013-04-03 02:02:33 +02:00
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

Benjamin Peterson d3f41fe121 merge 3.3 (#17610) 2013-04-01 17:43:30 -04:00
Benjamin Peterson 6395241471 list slotdefs in offset order rather than sorting them (closes #17610) 
This means we can remove our usage of qsort() than relied on undefined behavior.
