By setting the `enable_coverage` environment variable during a build, the `--coverage` flag will be passed to the compiler and linker. This produces `gcno` "notes" files which are used to instrument coverage during execution.
Uses [cpp-coveralls][] to upload coverage information to the (free for open source projects) [coveralls.io][]. This requires a few things: * Setting `enable_coverage` to `yes` to produce `gcno` files * Installing the coveralls command via `pip` * Allowing `postgres` to write `gdca` files to our checked-out code * Allowing our own user to read these files once created * Uploading the coverage data to coveralls This is a bit ugly at the moment but hopefully this comment illuminates what's being done. We'll clean up when we have more projects using this service. [cpp-coveralls]: https://github.com/eddyxu/cpp-coveralls [coveralls.io]: https://coveralls.io/
For bragging rights/shame.

The high-level picture of what's going on here is we instrument the library to emit coverage information and then measure coverage during Once this is in |

Uses cpp-coveralls to upload coverage information to the (free for open source projects) coveralls.io.
It was possible to implement this entirely within the project (rather than editing any of the build tools in our tools gist) so I did that.
