Handles the case when reword is called and the `commit --amend` invokes
the pre-commit hook, when there is no stash the `git stash pop -q`
in that case leaves the rebase in an odd state.
Fixes by only calling the stash pop if changes were saved.
This pre-commit hook can be activated by copying or symlinking to
the .git/hooks directory
This particular commit hook is best suited for git versions < 1.8.2
The running of nosetests would be better suited for a push hook,
but those are not added until 1.8.2.
Removes from requirements_dev.txt, since requirements_dev.txt is
used in various unit testing environments, ipython, pyzmq, etc.
is extra weight that is being unecessarily pulled in.
Global state for the financial simulation environment is accessed through the
zipline.finance.trading module, which now contains a module variable:
environment.
Parameters are passed into an algorithm as a keyword argument, sim_params.
SimulationParameters creates a trading day index for the test period that
can be used to find trading days, calculate distance between trading days,
and other common operations. The sim params index is just selected from the
global state.
================
Details:
- adding delorean to the requirements.
- made index symbol a parameter for loading the benchmark data. changed
messagepack storage to be symbol specific.
- ported risk, performance, algorithm, transforms, batch transforms
and associated tests to use simulation parameters and global environment
- factory and sim factory use global state and sim params
- factory method parameter names now reflect the class expected
Moving to main requirements, since zipline will not run without
the treasury and benchmark data that we requests to fetch.
Upgrade is to keep current with latest release.
To handle, for instance, Columbus Day (Oct 10),
on which there is no treasury data.
We're only forward-filling data now, and
no longer searching both back and forward in time.
