eejfdd�Zdd� Z� ZS )� _JSONPrimera� Fast JSON primer and pre-converter
Prepare a data structure for JSON serialization. In an ideal world, priming
could be handled by the default hook of json.dumps(). Unfortunately the
hook treats Python 2 str as text while IPA considers str as bytes.
The primer uses a couple of tricks to archive maximum performance:
* O(1) type look instead of O(n) chain of costly isinstance() calls
* __missing__ and __mro__ with caching to handle subclasses
* inline code with minor code duplication (func lookup in enc_list/dict)
* avoid surplus function calls (e.g. func is _identity, obj.__class__
instead if type(obj))
* function default arguments to turn global into local lookups
* avoid re-creation of bound method objects (e.g. result.append)
* on-demand lookup of client capabilities with cached values
Depending on the client version number, the primer converts:
* bytes -> {'__base64__': b64encode}
* datetime -> {'__datetime__': LDAP_GENERALIZED_TIME}
* DNSName -> {'__dns_name__': unicode}
The _ipa_obj_hook() functions unserializes the marked JSON objects to
bytes, datetime and DNSName.
