[Olena] #229: Have Olena's BuildBot generate GitStats information

by Olena Trac

#229: Have Olena's BuildBot generate GitStats information -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: trivial | Milestone: Olena 1.1 Component: other | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Git statistics are generated by my (Roland's) account for a limited set of branches, each night. It'd be smarter to have one of the buildslave invoke a script running `gitstats` and uploading the result (as `lrde- upload.sh` does) prior to building the project. We could even filter branches (having statistics for all branches might not be relevant). -- Ticket URL: <https://trac.lrde.org/olena/ticket/229> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
