c5c3ba4bec Add _PyBytesWriter_Resize() function 
This function gives a control to the buffer size without using min_size.

2bf8993db9 Optimize bytes.fromhex() and bytearray.fromhex() 
Issue #25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now
between 2x and 3.5x faster. Changes:

* 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

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.

bytearray buffer, instead of using a bytes object.

c29e29bed1 Relax _PyBytesWriter API 
Don't require _PyBytesWriter pointer to be a "char *". Same change for
_PyBytesWriter_WriteBytes() parameter.

For example, binascii uses "unsigned char*".

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()

0923d1d8d7 The other half of Issue #1580: use short float repr where possible. 
Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.

Also addresses these, which are intertwined with the short repr
changes:

- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
    with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
    for floats.

a3b1ac8dca Added ',' thousands grouping to int.__format__. See PEP 378. 
This is incomplete, but I want to get some version into the next alpha. I am still working on:
Documentation.
More tests.
Implement for floats.

In addition, there's an existing bug with 'n' formatting that carries forward to thousands grouping (issue 5515).

c15a07333e make bytes(o) respect __bytes__ #2415 
This adds two new C-API functions: PyObject_Bytes and PyBytes_FromObject.
