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.
on the number of per-tick update that occur since they were duplicated
per each PerformancePeriod. Also opens up the path to cythonizing the
entire object
A cython __richcmp__ function isn't allowed to assume that its first
argument is the same as the type of the class to which it belongs, so
our code needs to account for either of its two arguments being of the
wrong type.
Furthermore, the correct way for __richcmp__ to handle when it doesn't
know how to do a comparison is to return NotImplemented.
Python 3 for some reason doesn't like usage of the cmp() built-in, so
instead of using cmp(), just subtract the two ints being compared.
In addition to making this work with Python 3, it should also be more
performant since it no longer requires calling the cmp() method.
The >= comparison for the Cythonized Security object was actually
doing <=. Fix this and add unit tests for all the Security object rich
comparison operators.
Now version testing will only be run if the pandas version is
current. This is to allow the test matrix to pass on travis.
The version must be updated in file whenever pandas is upgraded.
The class is not yet used. Adding this class is part of the effort to allow Zipline
simulation of more types of assets than stocks.
DEV: Adds build_ext to .travis.yml
Previously the class SerializeableZiplineObject was used to
house basic __setstate__ and __getstate__ methods. It wasn't
really doing much that was helpful, so it is now gone.
Some unit tests for test_tradingcalendar failed on 2015-03-01, because the
addition of 365 days put the end date at 2016-02-29; when the replaces
the year on that date it fails because there is no 2017-02-29.
Instead use relativedelta with a year argument which accounts for leap
years.
Fixes the following test failure:
```

as it is a backwards compat. Without sorting the orders are filled by
order date. With sorting the orders are moved to back of queue after
partil fills. If all orders are fully filled, there is no
deviation. Also there is no portfolio difference as this is about
assigning fills to equivalent orders.
