Even with OrderedDict, the plistlib will still output the dict in its own order. Search for sorted(d.items()) in and you will know why. It is certainly warm-hearted to sort this before putting it into plist file but I think sometimes we just want a customized order.

I think this is not a bug. plistlib api accepts dict (not OrderedDict) and sorted output is a valid output. plistlib sorts dictionaries to be consistent with Apple's tools.

property list format [1] uses CFDictionary [2] with CFString keys. CFDictionary is unordered and the plist example in the format [1] is unordered too. But plutil [3] command sorts dictionaries. It is easy to observe by self-converting plist files with "plutil -convert xml1 test.plist" command.

Thanks for giving out docs and start a detail discussion on this Mher!

Sorry I'm not familiar with Apple plist tool (I'm using cocos2d-x on win32 for the moment...) Are you saying that plutil is used everytime we output a valid plist?

Another thing is whether the example in [1] is valid or not? If it is, I think we should provide unordered functionality.

The OrderedDict is subclass of dict and thus is acceptable as plistlib input. Actually when I remove the line for sort, the plist output as expected (with not order).

I'm reworking the patch in #14455 and one of the things I intend to do is to add a keyword argument that controls whether or not the keys in dictionaries will be sorted by plistlib.

Awesome. Thanks Ronald!
