tox: bump the pinned flake8 and pylint version (#1029)

2021-09-21T20:28:30+00:00

tox: bump the pinned flake8 and pylint version * pylint: fix W1406 (redundant-u-string-prefix) The u prefix for strings is no longer necessary in Python >=3.0. * pylint: disable W1514 (unspecified-encoding) From https://www.python.org/dev/peps/pep-0597/ (Python 3.10): The new warning stems form https://www.python.org/dev/peps/pep-0597, which says: Developers using macOS or Linux may forget that the default encoding is not always UTF-8. [...] Even Python experts may assume that the default encoding is UTF-8. This creates bugs that only happen on Windows. The warning could be fixed by always specifying encoding='utf-8', however we should be careful to not break environments which are not utf-8 (or explicitly state that only utf-8 is supported). Let's silence the warning for now. * _quick_read_instance_id: cover the case where load_yaml() returns None Spotted by pylint: - E1135 (unsupported-membership-test) - E1136 (unsubscriptable-object) LP: #1944414

user-data: jinja template to render instance-data.json in cloud-config

2018-09-11T17:31:46+00:00

Allow users to provide '## template: jinja' as the first line or their #cloud-config or custom script user-data parts. When this header exists, the cloud-config or script will be rendered as a jinja template. All instance metadata keys and values present in /run/cloud-init/instance-data.json will be available as jinja variables for the template. This means any cloud-config module or script can reference any standardized instance data in templates and scripts. Additionally, any standardized instance-data.json keys scoped below a '' key will be promoted as a top-level key for ease of reference in templates. This means that '{{ local_hostname }}' is the same as using the latest '{{ v#.local_hostname }}'. Since instance-data is written to /run/cloud-init/instance-data.json, make sure it is persisted across reboots when the cached datasource opject is reloaded. LP: #1791781

pylint: pay attention to unused variable warnings.

2018-04-20T03:30:08+00:00

This enables warnings produced by pylint for unused variables (W0612), and fixes the existing errors.

renderer: support unicode in render_from_file.

2018-04-12T21:51:07+00:00

If a file passed to render_from_file had non-ascii text then jinja in python2 would decode as ascii, which would cause UnicodeDecodeError. This issue can be re-created in python2 with just: 'can\xe2\x80\x99t'.decode() The solution here is to explicitly pass in unicode supporting type (py3 str, py2 unicode). Those are six.text_type. Then jinja does not try to decode. The reason we hit this is that load_file calls decode_binary. decode_binary believes it has no work to do if it got a six.string_types. isinstance('can\xe2\x80\x99t', six.string_types) == True So it returns the original string which will blow up for jinja. Our fix here then is to load the file in binary mode and explicitly decode it to utf-8. Then in python2 we'll have a unicode type and in python3 we'll have a string type.

pylint: fix all logging warnings

2017-04-21T14:14:47+00:00

This will change all instances of LOG.warn to LOG.warning as warn is now a deprecated method. It will also make sure any logging uses lazy logging by passing string format arguments as function parameters.

LICENSE: Allow dual licensing GPL-3 or Apache 2.0

2016-12-22T22:04:28+00:00

This has been a recurring ask and we had initially just made the change to the cloud-init 2.0 codebase. As the current thinking is we'll just continue to enhance the current codebase, its desirable to relicense to match what we'd intended as part of the 2.0 plan here. - put a brief description of license in LICENSE file - put full license versions in LICENSE-GPLv3 and LICENSE-Apache2.0 - simplify the per-file header to reference LICENSE - tox: ignore H102 (Apache License Header check) Add license header to files that ship. Reformat headers, make sure everything has vi: at end of file. Non-shipping files do not need the copyright header, but at the moment tests/ have it.
