wic: use next builtin instead of .next method

2016-05-14T22:05:14+00:00

Generators in Python 3 don't have .next method. It's recommended to use 'next' builtin instead. As it also present in Python >= 2.6 it should make wic code compatible with both Python 2 and Python 3.

wic: don't encode unicode strings

2016-05-14T22:05:14+00:00

Removed check for unicode type as it doesn't work in Python 3. This check is not needed for wic as all its output seem to be strings. This allows to run code under both pythons.

wic: decode output of subprocess.communicate

2016-05-14T22:05:14+00:00

stdeout and stderr content returned by communicate API has different types in Python 3(bytes) and Python 2(string). Decoding it to 'utf-8' makes it unicode on both pythons. Decoded stdout and stderr output to utf-8 to make the code working under both Python 2 and Python 3.

wic: use // operator instead of /

2016-05-14T22:05:14+00:00

Division operator works differently in Python 3. It results in float unlike in Python 2, where it results in int. Explicitly used "floor division" operator instead of 'division' operator. This should make the code to result in integer under both pythons. [YOCTO #9412] (From OE-Core rev: 997ff239bd753a7957cc14c6829b2f093d9bcef6) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: use find_executable in favor of bb.utils.which

2016-05-14T22:05:14+00:00

As bitbake is not ported to Python 3 yet it's better to avoid using its APIs as much as possible to be able to test wic under Python 3 at least partially. Used distutils.spawn.find_executable API in favor of bb.utils.which to get path of the command to run.

wic: don't use L suffix for integers

2016-05-14T22:05:13+00:00

This suffix is not supported by Python 3. Wic code works without it on Python 2 too, so it's safe to remove it. [YOCTO #9412] (From OE-Core rev: 296db7e33bd71585cac63dc78c2c95bc619b4a86) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: refactor pluginbase

2016-05-14T22:05:13+00:00

Wic plugin machinery implemented using metaclasses. Reimplemented plugin machinery using this advice from https://wiki.python.org/moin/PortingToPy3k/BilingualQuickRef Syntax for creating instances with different metaclasses is very different between Python 2 and 3. Use the ability to call type instances as a way to portably create such instances. Now it should work under both Python 2 and Python 3.
