[PATCH 0/8] Codespeed perf results

This patch series is built on top of cc/perf-run-config which recently graduated to master.

It makes it possible to send perf results to a Codespeed server. See https://github.com/tobami/codespeed/ and web sites like http://speed.pypy.org/ which are using Codespeed.

The end goal would be to have such a server always available to track how the different git commands perform over time on different kind of repos (small, medium, large, ...) with different optimizations on and off (split-index, libpcre2, BLK_SHA1, ...)

With this series and a config file like:

$ cat perf.conf
[perf]
        dirsOrRevs = v2.12.0 v2.13.0
        repeatCount = 10
	sendToCodespeed = http://localhost:8000
	repoName = Git repo
[perf "with libpcre"]
        makeOpts = "DEVELOPER=1 USE_LIBPCRE=YesPlease"
[perf "without libpcre"]
        makeOpts = "DEVELOPER=1"

One should be able to just launch:

$ ./run --config perf.conf p7810-grep.sh

and then get nice graphs in a Codespeed instance running on http://localhost:8000.

Caveat ~~~~~~

For now one has to create the "Git repo" environment in the Codespeed admin interface. (We send the perf.repoName config variable in the "environment" Codespeed field.) This is because Codespeed requires the environment fields to be created and does not provide a simple way to create these fields programmatically.

I might try to work around this problem in the future.
