NAME

       pybit-client - buildd client script to perform build jobs using pybit queues.

SYNOPSIS

       pybit-client [options]

DESCRIPTION

       pybit-client receives messages from the controller to create a specific package build
       using the specified version control system. The client feeds status messages back to the
       controller.

USAGE

       pybit-client runs as a single-instance daemon by default. The standard daemon control
       interface is supported:

           invoke-rc.d pybit-client stop
           invoke-rc.d pybit-client start
           update-rc.d pybit-client disable
           update-rc.d pybit-client enable

DAEMON CONFIGURATION

       Certain values are set using debconf at package installation but values can also be set in
       /etc/pybit/client/client.conf and the relevant debconf settings can be updated using
       dpkg-reconfigure pybit-client. The configuration file is in JSON format.

       clientid - The clientid string for this client (must not be empty and needs to be unique
       for each client using any one RabbitMQ server).

       host_arch - The native architecture of this client, e.g. i386.

           dpkg-architecture -qDEB_BUILD_ARCH

       use_lvm - Whether lvm snapshots are in use (default is true).

       distribution - The distribution in use. e.g. Debian.

           dpkg-vendor --query vendor

       pkg_format - Tag used by each build client to screen out unsupported binary build formats,
       e.g. Debian clients will check for deb and RPM clients would check for rpm.

       buildroot - The buildd location on the client filesystem. Default: /home/buildd/pybit

       host - The location of the RabbitMQ server which sends the build messages. This can be
       omitted during initial setup and testing but needs to be specified and the client
       restarted or no builds will be started.

       port - Override the standard port of 5672 for the RabbitMQ server.

       suites - NEW in 0.4.1 JSON list of the suites which this client can support - names must
       match the Distribution: specified in the changelog of relevant packages and must also
       match an alias for a configured schroot chroot.

            "suites": [ "unstable" ],

            "suites": [ "unstable", "squeeze-backports" ],

       The suite field used in 0.4.0 has been removed - clients will not start unless at least
       one suite is specified in the suites list. See also /usr/share/pybitclient/client.conf

       userid - If the RabbitMQ server uses authentication, override the default username of
       guest.

       password - If the RabbitMQ server uses authentication, override the default password of
       guest.

       vhost - If the RabbitMQ server uses a specific VHost, override the default of /.

       dput - options passed down to dput - see dput (1). The default is -U to stop dput writing
       .upload files.

       dput_dest - The codename of the location to upload the built packages (must not be empty
       as the default for dput is typically to upload to ftp-master.debian.org).

       poll_time - frequency with which this client checks the queues for new messages. Measured
       in seconds. Default: 60 seconds.

       debsignkey - keyID to be used to sign the .changes files from this buildd. If empty or
       omitted, changes files will never be signed.  The specified key MUST NOT use a passphrase.
       The key must be usable by the user running pybit-client - check with

           gpg --list-secret-keys

       dry_run - initially, clients are setup in dry run mode which means that commands are
       echoed to the terminal instead of being executed, to allow testing of new setups. To
       enable builds on the client, edit /etc/pybit/client/client.conf to change the value for
       dry_run to false.

SCHROOT CONFIGURATION

       The detailed process of creating chroots suitable for schroot is covered in the sbuild
       documentation (schroot.conf (5)) and amounts to using a tool like debootstrap to create a
       Debian build environment in a subdirectory (which may or may not be also the mountpoint of
       an LVM snapshot) and then configuring that chroot to have the relevant apt sources and
       pre-installed packages (e.g. build-essential and dpkg-dev).

       Note: when creating a chroot for schroot, remember to use the --variant=buildd option to
       debootstrap and install fakeroot inside the chroot.

   Install pbuilder
       The pybit debianclient uses /usr/lib/pbuilder/pbuilder-satisfydepends-classic for the
       dependency resolution test, so the pbuilder package needs to be installed inside each
       build chroot.

   Naming the chroots
       The pybit client will expect to be able to use a chroot (or an alias for a chroot) which
       matches the suite specified in the build request. If using version control hooks, this
       suite is likely to come from the Distribution field of the output of dpkg-parsechangelog.
       Ensure that any client has a suitable chroot listed in the output of schroot -l.

       pybit-client only listens to queues which match the listed suites in
       /etc/pybit/client/client.conf.

       The syntax for the suites configuration value changed in version 0.4.1 to support multiple
       suites within a JSON list:

            "suites": [ "unstable", "squeeze-backports" ],

       Clients running 0.4.0 need to have the configuration file updated for 0.4.1 or the client
       will fail to start as it will be unable to bind to the necessary queues.

   Testing the chroots
       There is a test script (/usr/share/pybitclient/buildd-test.py) which can be used alongside
       a test schroot to run through the buildd commands and then do the upload. (What happens to
       that upload is dependent on the next step, it just sits in an incoming directory
       initially.)

   Configuring the upload handler
       Set up dput by editing /etc/pybit/client/dput.cf to provide a usable upload configuration.
       The format of this file is the same as ~/.dput.cf and is passed to dput using the -c
       option internally. See dput.cf (5)

SETTING UP THE PYBIT SERVER TO WORK WITH CLIENTS

       The clients are only one part of pybit. pybit-web provides the server which will provide
       jobs for the clients. See pybit-web (1).
