Victor Stinner 74e8fac3c8 Issue #25301: Fix compatibility with ISO C90 2015-10-05 13:49:26 +02:00
Victor Stinner 1d65d9192d Issue #25301: The UTF-8 decoder is now up to 15 times as fast for error
handlers: ``ignore``, ``replace`` and ``surrogateescape``.

Victor Stinner eb36fdaad8 Fix _PyUnicodeWriter_PrepareKind()
Initialize kind to 0 (PyUnicode_WCHAR_KIND) to ensure that
_PyUnicodeWriter_PrepareKind() handles correctly read-only buffer: copy the
buffer.

Serhiy Storchaka 29e68edbf4 Issue #24848: Fixed bugs in UTF-7 decoding of misformed data:
1. Non-ASCII bytes were accepted after shift sequence.
2. A low surrogate could be emitted in case of error in high surrogate.
3. In some circumstances the '\xfd' character was produced instead of the
replacement character '\ufffd' (due to a bug in _PyUnicodeWriter).

Raymond Hettinger ac2ef65c32 Make the unicode equality test an external function rather than in-lining it.
The real benefit of the unicode specialized function comes from
bypassing the overhead of PyObject_RichCompareBool() and not
from being in-lined (especially since there was almost no shared
data between the caller and callee).  Also, the in-lining was
having a negative effect on code generation for the callee.

Victor Stinner 1912b39def _PyUnicodeWriter_WriteStr() now checks that the input string is consistent
in debug mode to detect bugs earlier.

_PyUnicodeWriter_Finish() doesn't check if the read only string is consistent,
