This is technically wrong. The documentation states that:
"Note that None may be returned if no handler handles the request
(though the default installed global OpenerDirector uses
UnknownHandler to ensure this never happens)."
This is super marginal and making it optional causes a few dozen
errors in an internal dropbox code base.
* local_addr and server_hostname are optional and default to None.
* If sock is given, none of host, port, family, proto, flags and
local_addr should be specified.
This gets imported from `_ast`, so the definition was
redundant. This causes problems with the new mypy semantic
analyzer, as it will flag the redefinition as an error.
* HTTP Handler class annotations for py2/urllib2 & py3/urllib.request
Add full annotations for the following classes:
* Python 2:
* `urllib2.AbstractHTTPHandler`
* `urllib2.HTTPHandler`
* `urllib2.HTTPsHandler`
* Python 3:
* `urllib.request.AbstractHTTPHandler`
* `urllib.request.HTTPHandler`
* `urllib.request.HTTPsHandler`
This information is largely undocumented, and was obtained by directly examining
the Python source code:
* Python 2 (v2.7.15) - https://github.com/python/cpython/blob/v2.7.15/Lib/urllib2.py#L1115-L1243
* Python 3 (v3.7.1) - https://github.com/python/cpython/blob/v3.7.1/Lib/urllib/request.py#L1224-L1364
`urllib2.AbstractHTTPHandler.do_open` takes as a parameter either
`HTTPConnection` or `HTTPSConnection`--one of the classes, not an instance of
either--and constructs an object using only a few of the parameters that either
constructor could use. `HTTPConnectionProtocol` in `stdlib/2/httplib.pyi`
follows a similar patten to `HTTPConnectionProtocol` added to
`stdlib/3/http/client.pyi` in pull request #2582 to describe the type of the
`http_class` that is passed to `do_open`.
The python3 charset stubs didn't include certain necessary module level
constansts (like `QP`) and wrongly defined the arguments to some of
the functions in the module. This is no longer the case.
Fixes#2767
`logging.getLevelName()` can take either an `int` and returns a `str` or
a `str` and returns an `int` when the level name (`str`) or level
(`int`) is one of the registered log levels. If the value passed in
isn't one of the registered log levels, it returns the string `"level
%s" % lvl` where `lvl` is the value passed in to the function.
All these attributes can be seen when using `dir(type)`.
In the future we should be discussing if certain methods on object (like
__eq__) should really be there. IMO this should be defined on type where it
actually also appears when using `dir`.
