Adds support for specifying additional masters to send results to.
The config file, named "builderbot-config", must be located in
osutil.CamliConfigDir(); on Unix, it will be under
$XDG_CONFIG_HOME/camlistore/, if XDG_CONFIG_HOME set, or
~/.config/camlistore/. On Windows it will be under %APPDATA%\Camlistore\.
The expected format is one host per line, comments are not allowed and used
only for illustration below. Some examples:
# Post to default path on host1, no user auth.
http://host1
# Post to / on host2, no user auth.
http://host2/
# Post to /other/path on host3, no user auth.
http://host3/other/path
# Post to default path on host4, user 'user', password 'pass'.
http://user:pass@host4
# Post to / on host4 port 7070, user 'user', password 'pass'.
http://user:pass@host4:7070/
This change also explicitly sets GOPATH to the copy of camlistore.org checked
out by the master before building the builder, and starting the build run.
This ensures we're not building against a random checkout of camlistore
pointed to by the user's environment.
The directory of the checked out source is moved from ${PWD}/camlistore.org
-> ${PWD}/src/camlistore.org so GOPATH can be set to $PWD and the requirement
of packages being under src/ is met.
