Issue #15984 : Merge PyUnicode doc from 3.5
2016-04-15 02:27:11 +00:00
6245cb3c01
Correct “an” → “a” with “Unicode”, “user”, “UTF”, etc
...
This affects documentation, code comments, and a debugging messages.

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

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

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.

Relax _PyBytesWriter API
...
Don't require _PyBytesWriter pointer to be a "char *". Same change for
_PyBytesWriter_WriteBytes() parameter.
For example, binascii uses "unsigned char*".

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()

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.
2009-04-16 20:16:10 +00:00
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).

Code review of the new buffer protocol. Mostly add questions that should

be answered with the comments removed.
There are many places that require checks when doing arithmetic for memory
sizes when allocating memory. Otherwise, overflow is possible with
a subsequent crash.
Fix SF #1777057 which was a result of not initializing the new BufferError
properly. Had to update the test for exceptions for BufferError too.

Optimizations for bytes reallocation.

This uses up to 12.5% overallocation, not entirely unlike list_resize().
Could probably use more tweaks for odd allocation patterns, TBD.
Also add __alloc__() method which returns the actually allocated size.
