Bump structlog from 20.2.0 to 21.2.0

[dependabot]

Bumps structlog from 20.2.0 to 21.2.0.

Release notes

Sourced from structlog's releases.

21.2.0

Highlights

• Support for for beautiful (and helpful!) exceptions by integrating ConsoleRenderer with rich or better-exceptions.
• Helpers to access thread-local and context-local context.
• Deeper contextvars support.

---

Backward-incompatible changes:

• To implement pretty exceptions (see Changes below), structlog.dev.ConsoleRenderer now formats exceptions itself.

  Make sure to remove format_exc_info from your processor chain if you configure structlog manually. This change is not really breaking, because the old use-case will keep working as before. However if you pass pretty_exceptions=True (which is the default if either rich or better-exceptions is installed), a warning will be raised and the exception will be renderered without prettyfication.

Deprecations:

none

Changes:

• structlog is now importable if sys.stdout is None (e.g. when running using pythonw). #313

• structlog.threadlocal.get_threadlocal() and structlog.contextvars.get_contextvars() can now be used to get a copy of the current thread-local/context-local context that has been bound using structlog.threadlocal.bind_threadlocal() and structlog.contextvars.bind_contextvars(). #331 #337

• structlog.threadlocal.get_merged_threadlocal(bl) and structlog.contextvars.get_merged_contextvars(bl) do the same, but also merge the context from a bound logger bl. Same pull requests as previous change.

• structlog.contextvars.bind_contextvars() now returns a mapping of keys to contextvars.Tokens, allowing you to reset values using the new structlog.contextvars.reset_contextvars(). #339

• Exception rendering in structlog.dev.ConsoleLogger is now configurable using the exception_formatter setting. If either the rich or the better-exceptions package is present, structlog will use them for pretty-printing tracebacks. rich takes precedence over better-exceptions if both are present.

  This only works if format_exc_info is absent in the processor chain. #330 #349

• All use of colorama on non-Windows systems has been excised. Thus, colors are now enabled by default in structlog.dev.ConsoleRenderer on non-Windows systems. You can keep using colorama to customize colors, of course. #345

• The final processor can now return a bytearray (additionally to str and bytes). #344

21.1.0

Backward-incompatible changes:

none

Deprecations:

none

Changes:

• structlog.threadlocal.wrap_dict() now has a correct type annotation. #290
• Fix isolation in structlog.contextvars. #302
