Changes the overlap behavior so that it is an error to write data which
would have two companies holding the same ticker. Other than one test
around which company would win in that case, all the other tests are
passing. That single test has been changed to check the write-time
error.
- Generate links to sourcecode via the Sphinx `viewcode` extension.
- Generate reference docs for Asset/Equity/Future, AssetFinder, and
AssetDBWriter.
- Generate reference docs for Pipeline API classes.
- Fix broken links and formatting issues in the 0.8.4 whatsnew.
- Use embedsignature in _assets.pyx so that the signatures of Asset
subclasses are inspectable.
The AssetDBWriter class and its subclasses will
ultimately be responsible for creating the SQLite
database tables and writing data to these tables.
In the longer term AssetDBWriter and AssetFinder will
be decoupled, sharing only an SQLite connection.
However, for backward compatibility reasons this has
not yet been fully implemented.
Modify tests since AssetFinder no longer has a
metadata_cache attribute.
This commit refactors the Security cython class to Asset, and refactors some fields of the class accordingly. This change is so the terminology is consistent and correct when Asset is extended to asset types that are not securities, such as futures.
