access git revision of currently running pandas

[jangorecki]

I would like to know from inside the code which pandas git revision I am running at the moment. So I can easily confirm I am on proper branch/revision when testing some new features/bug fixes.
Is it possible in pandas? If it isn't I would like this issue to be FR for such functionality. Just git commit hash is enough.
In dask you can access this info with dask.__git_revision__.

I'm not very clear on the use case here - can you provide a concrete example of how this would be useful?

[jangorecki]

most common:

easily confirm I am on proper branch/revision when testing some new features/bug fixes

more complex would be to process pipelines using different versions of pandas simultaneously, so auditing git revision from each job in a pipeline.

[jorisvandenbossche]

Pandas development version already gives an abbreviated form of the git revision:

In [1]: pd.__version__
Out[1]: '0.24.0.dev0+54.g10aab3c'

That's not sufficient?

[jangorecki]

It is good but not sufficient. It still requires lookup to git repo to get commit sha.

@jangorecki feel free to make a PR like https://github.com/dask/dask/pull/1760/files

[TomAugspurger]

@jangorecki could you make a PR implementing this?

[jangorecki]

@TomAugspurger not anytime soon

Added pd.__git_version__ to reflect git sha commit version.
