This changes the equivalent functions listed for the Base-64, hex and Quoted-
Printable codecs to reflect the functions actually used. Also mention and
test the "quotetabs" setting for Quoted-Printable encoding.
Backported issues #19619: encode() and decode() methods and constructors
of str, unicode and bytearray classes now emit deprecation warning for known
non-text encodings when Python is ran with the -3 option.
Backported issues #20404: io.TextIOWrapper (and hence io.open()) now uses the
internal codec marking system added to emit deprecation warning for known non-text
encodings at stream construction time when Python is ran with the -3 option.
requires them. Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface.
* Fix seek() method of codecs.open(), don't write the BOM twice after seek(0)
* Fix reset() method of codecs, UTF-16, UTF-32 and StreamWriter classes
* test_codecs: use "w+" mode instead of "wt+". "t" mode is not supported by
Solaris or Windows, but does it really exist? I found it the in the issue.
calling __import__. This helps make the expected search locations for encoding
modules be more explicit.
One could use an explicit value for __path__ when making the call to __import__
to force the exact location searched for encodings. This would give the most
strict search path possible if one is worried about malicious code being
imported. The unfortunate side-effect of that is that if __path__ was modified
on 'encodings' on purpose in a safe way it would not be picked up in future
__import__ calls.
