Add the "Greatest" unit test framework (ISC licensed) to c-hglib codebase
This patch series is for the c-hglib project,
i.e. C bindings for Mercurial.
The project started in summer 2013 within the Google Summer of Code
program, and is currently hosted at
https://bitbucket.org/mpmselenic/c-hglib
The design plan for c-hglib is to implement three different
levels of abstraction:
0) raw level - pass a raw command string, get unparsed results
1) command level - function per command, returns results in native C
datatypes
2) "object" level - emulate important Mercurial internal APIs like
contexts with a native C paradigm
http://www.selenic.com/pipermail/mercurial-devel/2013-June/051651.html
As of today, only level 0 is fully completed.
When we first discussed testing for c-hglib, the first reaction
from Matt was "Mercurial doesn't do unit testing":
http://www.selenic.com/pipermail/mercurial-devel/2013-June/051640.html
see also this post in Matt's blog http://www.selenic.com/blog/?p=582
The objection is that while Mercurial has all good reasons
to avoid nailing its internal implementation with fine grain testing
(hg's internal can change anytime, only external compatibility
is guaranteed), c-hglib is a library and -exposes- a C API.
It makes perfect sense to have unit tests.
This patch incorporates a C unit test framework called "Greatest"
into the c-hglib code base.
Greatest is originally developed by Scott Vokes and is hosted at
https://github.com/silentbicycle/greatest
Greatest is licensed with the ISC License
http://en.wikipedia.org/wiki/ISC_license
which is functionally equivalent to the MIT License.
This permits c-hglib (which is MIT licensed)
to incorporate Greatest under MIT.
Greatest has the following features:
* single source file, header-only
* no dependencies
* 27K in size
* compatible with ANSI C89
* allows for the test suite to span over several files
favoring a manageable organization of things
* setup and teardown callbacks
* execution of specific tests only
* execution of specific suites only
* informative user feedback
* many other sweet macros
I showed this list to Matt at the 3.2 sprint and
he said this might make the deal.
