Step One: Suggested File System Layout
For the DragonFly builds I'm using:
- /bulklog for the bulk meta data and log files of each package
- /scratch as WRKOBJDIR
- /distfiles as DISTDIR
- /packages as PACKAGES
- separate physical file systems for /var and /usr/pkg
All file systems but those are read-only, /tmp and /dev need platform
specific handling either as tmpfs or link. ptyfs helps for /dev.
For parallel builds, /bulklog, /packages and /usr/pkgsrc are supposed to
be shared (null mounts, NFS). /usr/pkg and /var/db/pkg needs to be
per-node and /scratch should be per-node.
The defaults scripts will remove /usr/pkg and /var/db/pkg on the master
node as well. When using chroot sandboxes for the build, the master can
share a sandbox with one of the build instances.
Step Two: Preparing pbulk prefix
Install pkgtools/pbulk and possibly helper programs like screen into
LOCALBASE=/usr/pkg_bulk, PKG_DBDIR=/usr/pkg_bulk/.pkgdb. A full
bootstrap is the recommended approach. Copy /usr/pkg_bulk to the client
nodes for parallel builds.
The initial bootstrap and install may be performed with the following commands:
cd /usr/pkgsrc/bootstrap
./bootstrap --prefix=/usr/pkg_bulk --pkgdbdir=/usr/pkg_bulk/.pkgdb
If you have already performed a bootstrap into /usr/pkg_bulk then you may need
to remove that directory (rm -fr /usr/pkg_bulk) prior to starting the new
pbulk may be installed into /usr/pkg_bulk with the following:
cd /usr/pkgsrc/pkgtools/pbulk
env PATH=/usr/pkg_bulk/bin:/usr/pkg_bulk/sbin:${PATH} bmake package
The mk.conf file in /usr/pkg_bulk/etc/mk.conf should already have the
correct LOCALBASE and PKG_DBDIR settings.
Step Three: Configure pbulk
Setup general build parameters in mk.conf. Below is an example
fragment to add. On NetBSD this is typically /etc/mk.conf. For
non-NetBSD systems we will create a mk.conf in a temporary location,
/tmp/mk.conf for example, and include it in the bootstrap that will
be built in step (b).
(b) [not for NetBSD]
Build a binary bootstrap kit and override the included mk.conf with the
file created in (a). Compress the tarball with gzip. This is a new
bootstrap that is different from the one created in Step Two above.
This bootstrap kit is created by the following:
cd /usr/pkgsrc/bootstrap
./bootstrap --mk-fragment /tmp/mk.conf \
--gzip-binary-kit bootstrap_kit.tar.gz
Note that we have specified the make file fragment, /tmp/mk.conf, created
in step (a) above.
Edit /usr/pkg_bulk/etc/pbulk.conf:
- For NetBSD:
- bootstrapkit should be empty.
- make must be changed to /usr/bin/make.
- For non-NetBSD:
- bootstrapkit should be changed to the tarball in (b). Both master
and client nodes access this, so keep it in a shared location.
- master_mode=yes needs a proper list of client nodes.
- base_url goes into the report mail, the rsync targets are used
for uploads.
- for limited bulk builds, set limited_list to a file with one
location per line ("x11/gtk2" for example). Packages that are required
as dependencies will be added automatically.
Step Four: Running pbulk
/usr/pkg_bulk/bin/bulkbuild runs the full build. You may wish to run
this inside of screen (misc/screen) since a full bulk build may take
a very long time.
/usr/pkg_bulk/libexec/pbulk/{pre-build,scan,build,report,upload} are the
individual build phases. They depend on the execution of the phase
before. Exceptions are report and upload which both depend on build.
/usr/pkg_bulk/bin/bulkbuild-restart can be used to resume an aborted
build. If it failed after the actual build phase, report and upload should
be called individually though.
