build(deps): bump structlog from 21.2.0 to 22.1.0 in /requirements

[dependabot]

Bumps structlog from 21.2.0 to 22.1.0.

Release notes

Sourced from structlog's releases.

22.1.0

Highlights

This is a (too) big release, so it has many highlights!

Firstly, rendering exceptions in machine-readable logs (usually JSON) got a big upgrade: thanks to structlog.processors.dict_tracebacks you can now have fully structured exceptions in your logs!

To ease getting started with structlog, we're now shipping structlog.stdlib.recreate_defaults() that recreates structlog's default behavior, but on top of standard library's logging. The output looks the same, but it runs through logging's machinery and integrates itself easier. The default configuration now also merges your contextvars-based context, so enjoy structlog.contextvars.bind_contextvars() without configuring anything!

Another request wish that kept coming up is naming the message key differently than event. We're aware that nowadays keys like msg are more common, but structlog pre-dates the software that introduced and popularized it. To allow for more consistency across your platforms, structlog now ships structlog.processors.EventRenamer that allows you to rename the default event key to something else and additionally also allows you to rename another key to event.

❤️ Huge thanks to my GitHub sponsors, Tidelift subscribers, and Ko-fi buyers! ❤️

None of my projects would exist in their current form without you!

Full Changelog

Removed

• Python 3.6 is not supported anymore.
• Pickling is now only possible with protocol version 3 and newer.

Deprecated

• The entire structlog.threadlocal module is deprecated. Please use the primitives from structlog.contextvars instead.

  If you're using the modern APIs (bind_threadlocal() / merge_threadlocal()) it's enough to replace them 1:1 with their contextvars counterparts. The old approach around wrap_dict() has been discouraged for a while.

  Currently there are no concrete plans to remove the module, but no patches against it will be accepted from now on. #409

Added

• structlog.processors.StackInfoRenderer now has an additional_ignores parameter that allows you to filter out your own logging layer. #396
• Added structlog.WriteLogger, a faster – but more low-level – alternative to structlog.PrintLogger. It works the way PrintLogger used to work in previous versions. #403 #404
• structlog.make_filtering_bound_logger()-returned loggers now also have a log() method to match the structlog.stdlib.BoundLogger signature closer. #413
• Added structured logging of tracebacks via the structlog.tracebacks module, and most notably the structlog.tracebacks.ExceptionDictTransformer which can be used with the new structlog.processors.ExceptionRenderer to render JSON tracebacks. #407
• structlog.stdlib.recreate_defaults(log_level=logging.NOTSET) that recreates structlog's defaults on top of standard library's logging. It optionally also configures logging to log to standard out at the passed log level. #428
• structlog.processors.EventRenamer allows you to rename the hitherto hard-coded event dict key event to something else. Optionally, you can rename another key to event at the same time, too. So adding EventRenamer(to="msg", replace_by="_event") to your processor pipeline will rename the standard event key to msg and then rename the _event key to event. This allows you to use the event key in your own log files and to have consistent log message keys across languages.
• structlog.dev.ConsoleRenderer(event_key="event") now allows to customize the name of the key that is used for the log message.

Changed

• structlog.make_filtering_bound_logger() now returns a method with the same signature for all log levels, whether they are active or not. This ensures that invalid calls to inactive log levels are caught immediately and don't explode once the log level changes. #401
• structlog.PrintLogger – that is used by default – now uses print() for printing, making it a better citizen for interactive terminal applications. #399
• structlog.testing.capture_logs now works for already initialized bound loggers. #408
• structlog.processors.format_exc_info() is no longer a function, but an instance of structlog.processors.ExceptionRenderer. Its behavior has not changed. #407
• The default configuration now includes the structlog.contextvars.merge_contextvars processor. That means you can use structlog.contextvars features without configuring structlog.

Fixed
