Detailed steps to reproduce the problem
>>> from pymongo.uri_parser import parse_uri >>> parse_uri("mongodb://cluster0.example.mongodb.net/myDatabase?retryWrites=true&retryReads=true").get("options") Unknown macro: \{'retryWrites'} >>> type(parse_uri("mongodb://cluster0.example.mongodb.net/myDatabase?retryWrites=true&retryReads=true").get("options")) <class 'pymongo.common._CaseInsensitiveDictionary'>
It led to a surprising behavior (unexpected lowercased options) when merging the options with another dictionary:
>>> options = {'authSource': 'auth', 'retryWrites': True}
>>> opts = parse_uri("mongodb://cluster0.example.mongodb.net/myDatabase?retryWrites=true&retryReads=true").get("options")
{'retryWrites': True, 'retryReads': True}
(Pdb) {**options, **opts}
{'authSource': 'auth', 'retryWrites': True, 'retrywrites': True, 'retryreads': True}
(Pdb) type(opts)
<class 'pymongo.common._CaseInsensitiveDictionary'>
(Pdb) type(options)
<class 'dict'>
Shane said, "I always hated _CaseInsensitiveDictionary. It's probably a bug that we return it to the user. It's supposed to be private."
Definition of done: what must be done to consider the task complete?
parse_uri("...").get("options")
returns a plain dictionary.
