If an exception were to be thrown in `Logger.isEnabledFor` (say, by asyncio
|
|
timeouts or stopit) , the `logging` global lock may not be released
|
|
appropriately, resulting in deadlock. This change wraps that block of code
|
|
with `try...finally` to ensure the lock is released.

A change was made to logging.config.dictConfig to avoid converting instances
|
|
of named tuples to ConvertingTuple. It's assumed that named tuples are too
|
|
specialised to be treated like ordinary tuples; if a user of named tuples
|
|
requires ConvertingTuple functionality, they will have to implement that
|
|
themselves in their named tuple class.
