Issue #18722: Remove uses of the "register" keyword in C code.

Simplify and optimize formatlong()

Fri, 27 Apr 2012 23:40:13 +0200

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.

Thu, 16 Apr 2009 20:16:10 +0000

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.

Added ',' thousands grouping to int.format. See PEP 378.

Fri, 03 Apr 2009 14:45:06 +0000

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).

make bytes(o) respect bytes #2415

Tue, 26 Aug 2008 16:46:47 +0000

make bytes(o) respect __bytes__ #2415

This adds two new C-API functions: PyObject_Bytes and PyBytes_FromObject.

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.

Rough and dirty job -- allow concatenation of bytes and arbitrary

Optimizations for bytes reallocation.

Fri, 05 May 2006 04:34:18 +0000

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.

PS. I'm now convinced that we need something like "".join(); later.
