that is built. This saves a lot of time, especiall when the
parallelism (the number of jobs per machine, not the number of
machines) is low.
However, the build script only blows away /usr/local and
/usr/X11R6, so if there is a port that does some nasty things
outside that area, all bets are off.
(2) Better load balancing. Now, each machine reports its own
load in a form of a text file, which the master merely aggregates
to pick the lowest-loaded machine(s). Other than generally
running faster (and more up-to-date) under loaded conditions, the
master script will no longer hold up until a timeout when a
machine goes down.

This is the parallelized package building system. Many thanks to

Steve Price for helping me put this together.

In the following, ${branch} is either "2.2" or "3.0" depending on
|
|
which packages you intend to build.
|
|
|
|
Note that this system is still under development. It will require a
|
|
substantial amount of effort to set up initially, and the following is
|
|
probably missing a lot of stuff. Please let me know of any warts you
|
|
find.
|
|
|
|
(1) One of the machines are to be designated as the "master". It is
|
|
defined in the portbuild script. There is also a "buildroot"
|
|
directory where everything should reside on the master machine.
|
|
It is defined in ports/Makefile and the portbuild script. Copy
|
|
everything under this directory there and make necessary changes.
|
|
|
|
(2) On the master, check out the ports tree under
|
|
${buildroot}/usr/ports, the appropriate source tree under
|
|
${buildroot}/${branch}/src and the doc tree under
|
|
${buildroot}/usr/opt/doc. These directories have to be NFS
|
|
exported to the build machines. (Hint: you should probably add
|
|
"-alldirs" to /etc/exports.)
|
|
|
|
(3) Setup ssh for root between the build machines and the master. It
|
|
has to work in both directions.
|
|
|
|
(4) Put the list of machines you have in "mlist". There is a sample
|
|
provided in this directory. Each line should have two entries,
|
|
"hostname" and "power". The "hostname" is self-explanatory; the
|
|
"power" entry generally discribes how many compilations that
|
|
machine can run in parallel. It is only relative, so designating
|
|
two machines 1 and 2 is the same as having them as 10 and 20
|
|
(modulo any rounding errors).
|
|
|
|
Note that you can put the master here as well, but our experience
|
|
is that our NFS is likely to act up when the master is too busy.
|
|
Even with a two-processor P6-200, we had to refrain from running
|
|
any compilations on the master to get NFS to work reliably.
|
|
|
|
(5) Go to ${branch}/bindist and follow the instructions in the README
|
|
files there to create the bindist tarball.
|
|
|
|
(6) Generate an XFree86 tarball in ports/x11/XFree86. Use
|
|
PLIST.stripped to create a smaller version. (You can use it by
|
|
setting 'PLIST=${PKGDIR}/PLIST.stripped'.) Put it in
|
|
${branch}/tarballs.
|
|
|
|
(7) If you have Motif, generate a Motif tarball by using
|
|
ports/x11-toolkits/Motif-dummy. Put it in ${branch}/tarballs.
|
|
|
|
(8) Copy ${branch}/tarballs and ${buildroot}/portbuild to same
|
|
directories on the build machines. Create a directory
|
|
${branch}/chroot on the build machines.
|
|
|
|
(9) Create the directory ${buildroot}/distfiles, ${branch}/{errors,logs}
|
|
and ${branch}/packages/All on the master. Copy the XFree86 and
|
|
Motif tarballs to the latter directory.
|
|
|
|
(10) Run the "reportload" script on the build machines in the
|
|
background (you can put reportload.sh in /usr/local/etc/rc.d to
|
|
run it automatically upon reboot), and then run the
|
|
"checkmachines" script on the master, again in the background.
|
|
This will check all the machines listed in "mlist" periodically
|
|
and print the list of least-loaded machines to "ulist".
|
|
|
|
(11) Run the "makeduds" script at ${buildroot}/usr/ports. The one
|
|
supplied is for building 2.2 packages on a 3.0 machines. For
|
|
3.0, you can replace it with just two lines:
|
|
|
|
unset DISPLAY
|
|
PARALLEL_PACKAGE_BUILD=t make ignorelist ECHO_MSG=true > ../../3.0/duds
|
|
|
|
(12) Run the "makeindex" script at ${buildroot}/usr/ports. The one
|
|
supplied is for building 2.2 packages on a 3.0 machines. For
|
|
3.0, you can replace it with just one line:
|
|
|
|
PORTSDIR=$(pwd) PARALLEL_PACKAGE_BUILD=t make index
|
|
|
|
(13) Run "make parallel > ../../${branch}/Makefile" in
|
|
${buildroot}/usr/ports to generate the Makefile.
|
|
|
|
(14) Go to ${branch}/packages/All on the master and type "make -k
|
|
-j<whatever> -f ../../Makefile &". Then wait. :)
|
|
|
|
(15) Note that the new scheme will not clean up the chroot dirs under
|
|
${buildroot}/${branch}/chroot on the build machines, but will
|
|
instead reuse them during the course of the build. Make sure you
|
|
delete them all when your bindist.tar changes.
