MacPorts Buildbot Scripts
This is a collection of scripts that will be run by the MacPorts Project's Buildbot buildslaves for continuous integration and precompilation of binary archives.
mpbb ("MacPorts Buildbot") driver script defines a subcommand for
each step of a build. These subcommands are implemented as separate
mpbb-SUBCOMMAND, but they are not intended to be
standalone programs and should not be executed as such. Build steps
should only be run using the
The defined build steps are:
Update base without updating the portindex.
mpbb --prefix /opt/local selfupdate
Checkout ports tree and update the portindex.
mpbb --prefix /opt/local --work-dir /tmp/scratch \ checkout \ [--ports-url https://github.com/macports/macports-ports.git] \ [--ports-commit 40c3ce0a26abc0d778754ecde9660bead94a2ffd]
Print one or more ports' subports to standard output.
mpbb --prefix /opt/local list-subports php cmake llvm-3.8 [...]
For each subport listed in step 3:
a. Install dependencies.
mpbb --prefix /opt/local install-dependencies php71
b. Install the subport itself.
mpbb --prefix /opt/local install-port php71
c. Gather archives.
mpbb --prefix /opt/local --work-dir /tmp/scratch \ gather-archives \ --archive-site https://packages.macports.org \ --staging-dir /tmp/scratch/staging
d. Upload. Must be implemented in the buildmaster.
e. Deploy. Must be implemented in the buildmaster.
f. Clean up. This must always be run, even if a previous step failed.
mpbb --prefix /opt/local cleanup
Subcommand scripts are sourced by the
mpbb driver. A script named
mpbb-SUBCOMMAND must define these two shell functions:
SUBCOMMAND(): Perform the subcommand's work and return zero on success and nonzero on failure.
SUBCOMMAND-usage(): Print to standard out a usage summary, a description of the subcommand's purpose, and the subcommand's options, but do not
exit. The output is passed through
fmt(1), so single newlines are not preserved.
Scripts may define additional functions as desired. For example, the
mpbb-list-subports script defines the required
list-subports-usage functions, as well as a
Subcommand scripts may use but not modify these global shell parameters:
$command: The name of the subcommand.
$option_prefix: The prefix of the MacPorts installation.
$option_jobs_dir: The path to a local copy of the jobs tools.
$option_log_dir: A directory for storing build logs.
$option_work_dir: A directory for storing temporary data. It is guaranteed to persist for the duration of an
mpbbrun, so it may be used to share ancillary files (e.g., a Subversion checkout of the ports tree) between builds of different ports.
$option_failcache_dir: A directory for storing information about previously failed builds which saves time because builds that are known to fail will not be attempted.
mpbbis written in bash and is known to be compatible with 3.2.17 through 3.2.57.

For development of
mpbb, we recommend the following setup:
- Install a separate copy of MacPorts, e.g. in
/opt/mports. See Install Multiple MacPorts Copies. It is not recommended to use your normal copy of MacPorts, since
mpbbwill do cleanup after installation and deactivate all active ports.
--prefix=/opt/mportsto use your custom prefix. You may also want to set
