Bump structlog from 18.2.0 to 20.1.0

[dependabot-preview]

Bumps structlog from 18.2.0 to 20.1.0.

Changelog

Sourced from structlog's changelog.

20.1.0 (2020-01-28)

Backward-incompatible changes:

none

Deprecations:

• This is the last version to support Python 2.7 (including PyPy) and 3.5. All following versions will only support Python 3.6 or later.

Changes:

• Added a new module structlog.contextvars that allows to have a global but context-local structlog context the same way as with structlog.threadlocal since 19.2.0. #201, #236
• Added a new module structlog.testing for first class testing support. The first entry is the context manager capture_logs() that allows to make assertions about structured log calls. #14, #234
• Added structlog.threadlocal.unbind_threadlocal(). #239
• The logger created by structlog.get_logger() is not detected as an abstract method anymore, when attached to an abstract base class. #229
• colorama isn't initialized lazily on Windows anymore because it breaks rendering. #232, #242

---

19.2.0 (2019-10-16)

Backward-incompatible changes:

• Python 3.4 is not supported anymore. It has been unsupported by the Python core team for a while now and its PyPI downloads are negligible.

  It's very unlikely that structlog will break under 3.4 anytime soon, but we don't test it anymore.

Deprecations:

none

Changes:

• Full Python 3.8 support for structlog.stdlib.
• Added more pass-through properties to structlog.stdlib.BoundLogger. To makes it easier to use it as a drop-in replacement for logging.Logger. #198
• structlog.stdlib.ProcessorFormatter now takes a logger object as an optional keyword argument. This makes ProcessorFormatter work properly with stuctlog.stdlib.filter_by_level(). #219
• structlog.dev.ConsoleRenderer now uses no colors by default, if colorama is not available. #215
• structlog.dev.ConsoleRenderer now initializes colorama lazily, to prevent accidental side-effects just by importing structlog. #210
• Added new processor structlog.dev.set_exc_info() that will set exc_info=True if the method's name is exception and exc_info isn't set at all. This is only necessary when the standard library integration is not used. It fixes the problem that in the default configuration, structlog.get_logger().exception("hi") in an except block would not print the exception without passing exc_info=True to it explicitly. #130, #173, #200, #204
• A best effort has been made to make as much of structlog pickleable as possible to make it friendlier with multiprocessing and similar libraries. Some classes can only be pickled on Python 3 or using the dill library though and that is very unlikely to change.
