Bug 607922 – sys-apps/portage: "DeprecationWarning: 'async' and 'await' will become reserved keywords in Python 3.7" warning with Python 3.6

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Arfrever Frehtes Taifersar Arahesis 2017-02-01 15:55:32 UTC]

Python 3.6 introduced warnings about invalid-in-future usage of async and await.

Documentation of valid usage:
https://docs.python.org/3.6/reference/compound_stmts.html#coroutines


In Portage:


$ export PYTHONWARNINGS="d,i::ImportWarning"
$ python3.6 -m compileall -fq *
pym/portage/sync/controller.py:117: DeprecationWarning: 'async' and 'await' will become reserved keywords in Python 3.7
  def async(self, emerge_config=None, repo=None, master_hooks=True):


$ grep -r "\.async" *
RELEASE-NOTES:                 SyncRepos.async: group sync and callback as composite task
RELEASE-NOTES:    - Bug 561234 SyncManager.async: initialize attributes before fork
pym/portage/emaint/modules/sync/sync.py:                return self._sync_manager.async(


Probably this "async" function should be renamed.
Probably "sync" function defined below also should be renamed for consistency.

The method has been renamed to sync_async:

Tests are enabled for Python 3.6 in travis now:
