Serhiy Storchaka 1ed017ae92 Issue #20440: Cleaning up the code by using Py_SETREF and Py_CLEAR. 
Old code is correct, but with Py_SETREF and Py_CLEAR it can be cleaner.
This patch doesn't fix bugs and hence there is no need to backport it.

methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__,
or __getstate__), can no longer be pickled.  Including memoryview.

complex() constructor, where it was not reachable.

Issue #25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now

* Use a fast-path working on a char* string for ASCII string
* Use a slow-path for non-ASCII string
* Replace slow hex_digit_to_int() function with a O(1) lookup in
  _PyLong_DigitValue precomputed table
* Use _PyBytesWriter API to handle the buffer
* Add unit tests to check the error position in error messages

Victor Stinner 772b2b09f2 Optimize bytearray % args 
Issue #25399: Don't create temporary bytes objects: modify _PyBytes_Format() to
create work directly on bytearray objects.

* Rename _PyBytes_Format() to _PyBytes_FormatEx() just in case if something
  outside CPython uses it
* _PyBytes_FormatEx() now uses (char*, Py_ssize_t) for the input string, so
  bytearray_format() doesn't need tot create a temporary input bytes object
* Add use_bytearray parameter to _PyBytes_FormatEx() which is passed to
  _PyBytesWriter, to create a bytearray buffer instead of a bytes buffer

Most formatting operations are now between 2.5 and 5 times faster.

Victor Stinner be75b8cf23 Issue #25349: Optimize bytes % int 
Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X.
_PyBytesWriter is now used to format directly the integer into the writer
buffer, instead of using a temporary bytes object.

Formatting is between 30% and 50% faster on a microbenchmark.
 2015-10-09 22:43:24 +02:00
Victor Stinner 6bd525b656 Optimize error handlers of ASCII and Latin1 encoders when the replacement 
string is pure ASCII: use _PyBytesWriter_WriteBytes(), don't check individual

* Rename repunicode to rep
* Clear rep object on error
* Factorize code between bytes and unicode path
