Hacking
This section provides some notes on how to hack on Hydra. To get the latest version of Hydra from GitHub:
$ git clone git://github.com/NixOS/hydra.git
$ cd hydra
To enter a shell in which all environment variables (such as PERL5LIB)
and dependencies can be found:
$ nix-shell
To build Hydra, you should then do:
[nix-shell]$ ./bootstrap
[nix-shell]$ configurePhase
[nix-shell]$ make
You start a local database, the webserver, and other components with foreman:
$ foreman start
You can run just the Hydra web server in your source tree as follows:
$ ./src/script/hydra-server
You can run Hydra's test suite with the following:
[nix-shell]$ make check
[nix-shell]$ # to run as many tests as you have cores:
[nix-shell]$ make check YATH_JOB_COUNT=$NIX_BUILD_CORES
[nix-shell]$ # or run yath directly:
[nix-shell]$ yath test
[nix-shell]$ # to run as many tests as you have cores:
[nix-shell]$ yath test -j $NIX_BUILD_CORES
When using yath instead of make check, ensure you have run make
in the root of the repository at least once.
Warning: Currently, the tests can fail
if run with high parallelism due to an issue in
Test::PostgreSQL
causing database ports to collide.
Working on the Manual
By default, foreman start runs mdbook in "watch" mode. mdbook listens
at http://localhost:63332/, and
will reload the page every time you save.
Building
To build Hydra and its dependencies:
$ nix-build release.nix -A build.x86_64-linux
