* Add Protocol and runtime to typing_extensions
* Use private type variable
* Fix typo
* Bound type variable for runtime to only class objects
* Conform to version check specification
* Add flags to pass on --warn-unused-ignores and --no-implicit-optional to mypy
* Make implicit Optional explicit in arg types (2and3 part)
* Convert {stdlib,third_party}/2 to explicit Optional
- Updates documentation related to previously required comment headers.
- Removes all comment headers from stubs
- Occasionally included a header for stubs that were noted to be incomplete or contained todo's.
* add typing.ContextManager for 3.6+ only
This fixes the easier part of #655.
Would it make sense to add a generic typing.ContextManager that exists in any Python version?
* update comment
* fix argument types for ContextManager.__exit__
* add AsyncContextManager
* add @asynccontextmanager
* typing.ContextManager now always exists
* back out async-related changes
Will submit those in a separate PR later
* fix import order
* AbstractContextManager only exists in 3.6+
* AbstractContextManager -> ContextManager
* Stubs for boto.kms
* Added types for params
* Added return type and fixed signatures(including review changes)
* Removed make_request from stub(https://github.com/python/mypy/issues/1237). Fixed Dict issue.
* Fixed typo
* Let's be precise about return type
* Added SQLAlchemy annotations
* Made Connection and Engine sublcasses of Connectable (python/typeshed#1018)
* Moved execute() from Connection to Connectable
* Made RowProxy a Mapping and removed Mapping inherited methods
* Made ResultProxy an Iterator of RowProxy
* Added most relevant methods for fetching of ResultProxy
* Added where(), group_by(), order_by() and limit() to Select
* Follow squalchemy module structure
* Created sqlalchemy.engine.result and moved ResultProxy and RowProxy
there
* Created sqlalchemy.engine.interfaces and moved Connectable there
* Added non-deprecated methods to Connectable: connect,
contextual_connect and scalar
* Fixed return type of scalar() to Any
* Missed ResultProxy scalar return
... had it in Connectable only.
I believe this covers both #647 and #719.
Moved sqlalchemy stubs from 2 to 2and3;
changed sqlalchemy/util/compat.pyi:37 to be of type typing.Text;
added incomplete stubs for sqlalchemy.orm.utils and slqalchemy.sql.elements.ColumnElement.
Starting with python/mypy#2521 mypy is performing stricter function signature
checks.
This makes the stubs diverge from the actual implementation but makes the stubs
internally consistent. Since this is an actual typing issue in the base
implementation, we need to defer to the original authors to fix it.
Sadly, in this case the breakage is rather fundamental and unlikely to get
fixed by upstream. Consider:
```
class AWSAuthConnection(object):
def make_request(self, method, path, headers=None, data='', host=None,
auth_path=None, sender=None, override_num_retries=None,
params=None, retry_handler=None): ...
class AWSQueryConnection(AWSAuthConnection):
def make_request(self, action, params=None, path='/', verb='GET'): ...
```
Hence, until we have a workaround for the error produced by Mypy, we're
excluding those stubs from being tested against.
Correctly detects calls to `register()` with a function of incompatible return
type. Correctly recognizes the `register()`, `dispatch()`, and
`_clear_cache()` methods on a generic function, as well as the `registry`
mapping.
Possible future improvements: it would be amazing if `register()` checked if
the first argument of the registered callable is indeed of valid type. This
would require Callable[] to support varargs. It would also be great if we
could read the arguments of the remaining arguments during `@singledispatch()`
and cross-check them during `register()` with the currently registered
implementation. Again, this would require Callable[] to become much more
advanced.
