Monitor and build the opam-repository, and display results on the web. It uses a patched version of OPAM to avoid the recompilation of already compiled packages (binary packages), and is completely incremental, i.e. not recomputing anything that has not changed since the last commit.
Currently, the results of running opam-builder on a 4-core server running Debian 8 are displayed here:
http://opam.ocamlpro.com/builder/html/report-last.html
The following dependencies are needed:
- ocp-build >= 1.99.19-beta
- OCaml >= 4.04
- aspcud (at least the version of Debian 8)
- jsonm
Then, run the following:
./configure
make
You also need a patched version of opam. Use the branch:
https://github.com/lefessan/opam/tree/2017-04-13-opam-builder
You should compile this patched version of opam, and install the
resulting binary in your PATH under the name opam.dev.
Since you are going to build the entire opam-repository, you should
make sure you have all the external dependencies available. This is
usually done by calling opam depexts. You might want to do it using
your standard OPAM setting before installing opam-builder.
See some scripts in the scripts directory:
-
install-builder.sh: this script will setup a directory BUILDER with two switches and a monitoring daemon. You should probably not run that script, but use it as a list of commands to use to setup your environment. -
restart-switch.sh: this script can be used in a switch, to launch a daemon watching this switch. -
restart-www.sh: this script can be used (after modification) to launch a daemon that will generate the JSON files when new reports are published.
