xref https://github.com/pandas-dev/pandas/pull/30034 codecs.open does `file = open(...)` before validating the encoding kwarg, leaving the open file behind if that validation raises. | |||

Does using with block similar to https://bugs.python.org/issue22831 solve this problem? | |||

Add try: ... except: file.close() raise | |||

Any reason not to just defer opening the file until after the codec has been validated, so the resource acquisition comes last? | |||

Many reasons. 1. It is simpler. 2. We will need a try/except in any case to prevent a leak if an exception be raised by other code following open(). 3. It matches the behavior of io.open(). | |||

Just quickly pinging the thread as a friendly reminder that PR 17666 is open and potentially close to mergeable, as it's been through two review cycles already (thanks Serhiy). If someone has the bandwidth to take another look, it would be greatly appreciated. Thanks! | |||
