<para>In order to provide pre-compiled binaries of third-party
|
|
applications for &os;, the Ports Collection is regularly
|
|
built on one of the <quote>Package Building Clusters.</quote>
|
|
Currently, the main cluster in use is at
|
|
<ulink url="http://pointyhat.FreeBSD.org"></ulink>.</para>
|
|
|
|
<para>Most of the package building magic occurs under the
|
|
<filename>/var/portbuild</filename> directory. Unless
|
|
otherwise specified, all paths will be relative to
|
|
this location. <replaceable>${arch}</replaceable> will
|
|
be used to specify one of the package architectures
|
|
(amd64, &i386;, ia64, and &sparc64;), and
|
|
<replaceable>${branch}</replaceable> will be used
|
|
to specify the build branch (5, 5-exp, 6, 6-exp, 7).

<note>
|
|
<para>Packages are no longer built for Release 4, nor
|
|
for the alpha architecture.</para>

</note>
|
|
|
|
<para>The scripts that control all of this live in
|
|
<filename>/var/portbuild/scripts/</filename>. These are the
|
|
checked-out copies from
|
|
<filename>/usr/ports/Tools/portbuild/scripts/</filename>.</para>
|
|
|
|
<para>Typically, incremental builds are done that use previous
|
|
packages as dependendencies; this takes less time, and puts less
|
|
load on the mirrors. Full builds are usually only done:</para>

<para>Although connected nodes are supported,

|
<replaceable>disconnected</replaceable> cluster node support has
|
|
been added. A disconnected node is
|
|
one that does not mount the cluster master via NFS. It could be
|
|
a remote node, for example. The cluster master rsync's the
|
|
interesting data (ports and src trees, bindist tarballs,
|
|
scripts, etc.) to disconnected nodes during the node-setup
|
|
phase. Then, the disconnected portbuild directory is
|
|
nullfs-mounted for chroot builds.</para>

|
|
onto

each of the <replaceable>${arch}</replaceable> nodes
|
|
which are connected nodes. In general, this is not true of the
|
|
disconnected nodes. Use <command>sudo</command> and check the

<hostid>portbuild.<replaceable>hostname</replaceable>.conf</hostid>

for the user and access details.</para>

<para>The <command>scripts/allgohans</command> script can

|
|
|
<para>The <command>scripts/checkmachines</command> script
|
|
is used to monitor the load on all the nodes of the
|
|
build cluster, and schedule which nodes build which ports.
|
|
This script is not very robust, and has a tendency to die.
|
|
It is best to start up this script on the build master
|
|
(e.g. <hostid>pointyhat</hostid>)
|
|
after boot time using a &man.while.1; loop.

<para>Package builds are performed in a

<literal>chroot</literal> populated by the

|
<filename>portbuild</filename> script using the
|
|
<filename><replaceable>${arch}</replaceable>/<replaceable>${branch}</replaceable>/tarballs/bindist.tar</filename>

file. This tarball is created by the
|
|
<command>mkbindist</command> script which reads the

file to decide how to create the tarball.</para>

create <filename>bindist.tar</filename>. In practice

this means that you must have already installed a world

<command>makeworld</command> script:</para>

forth, are cleaned by the scripts. If you are short of space,
|

you can also clean out <filename>ports/distfiles/</filename>.
|
|
Leave the <filename>latest/</filename> directory alone; it is
|
|
a symlink for the webserver.</para>
|
|
|
|
<note>
|
|
<para><literal>dosetupnodes</literal> is supposed to be run from
|
|
the <literal>dopackages</literal> script in the
|
|
<literal>-restart</literal> case, but it can be a good idea to
|
|
run it by hand and then verify that the clients all have the
|
|
expected job load. Sometimes,
|
|
<literal>dosetupnode</literal> cannot clean up a build and you
|
|
need to do it by hand. (This is a bug.)</para>

<para>Make sure the <replaceable>${arch}</replaceable> build

|
|
|
|
<note><para>The actual package build itself occurs in two
|
|
identical phases. The reason for this is that sometimes
|
|
transient problems (e.g. NFS failures, FTP sites being
|
|
unreachable, etc.) may halt a build. Doing things
|
|
in two phases is a workaround for these types of
|
|
problems.</para></note>
|
|
|
|
<para>Be careful that <filename>ports/Makefile</filename>
|
|
does not specify any empty subdirectories. This is especially
|
|
important if you are doing an -exp build. If the build
|
|
process encounters an empty subdirectory, both package build
|
|
phases will stop short, and an error similar to the following
|
|
will be written to
|
|
<filename><replaceable>${arch}</replaceable>/<replaceable>${branch}</replaceable>/make.[0|1]</filename>:
|
|
</para>
|
|
|
|
<screen><literal>don't know how to make dns-all(continuing)</literal></screen>
|
|
|
|
<para>To correct this problem, simply comment out or remove
|
|
the <literal>SUBDIR</literal> entries that point to empty
|
|
subdirectories. After doing this, you can restart the build
|
|
by running the proper <command>dopackages</command> command
|
|
with the <literal>-restart</literal> option.
|
|
</para>
|
|
|
|
<note>
|
|
<para>This problem also appears if you create a new category
|
|
<filename>Makefile</filename> with no <makevar>SUBDIR</makevar>s
|
|
in it. This is probably a bug.</para>

<title>Interrupting a Build</title>
|
|
|
|
<para>Interrupting a build is a bit messy. First you need to
|
|
identify the tty in which it's running (either record the output
|
|
of &man.tty.1; when you start the build, or use <command>ps x</command>
|
|
to identify it. You need to make sure that nothing else important
|
|
is running in this tty, e.g. <command>ps -t p1</command> or whatever.
|
|
If there is not, you can just kill off the whole term easily with
|
|
<command>pkill -t p1</command>; otherwise issue a
|
|
<command>kill -HUP</command> in there by e.g.
|
|
<command>ps -t p1 | awk '{print $1}' | xargs kill -HUP</command>. Replace
|
|
<replaceable>p1</replaceable> by whatever the tty is, of course.</para>
|
|
|
|
<para>The
|
|
package builds dispatched by <command>make</command> to
|
|
the client machines will clean themselves up after a
|
|
few minutes (check with <command>ps x</command> until they
|
|
all go away).</para>
|
|
|
|
<para>If you do not kill &man.make.1;, then it will spawn more jobs.
|
|
If you do not kill <command>dopackages</command>, then it will restart
|
|
the entire build. If you do not kill the <command>pdispatch</command>
|
|
processes, they'll keep going (or respawn) until they've built their
|
|
package.</para>
|
|
|
|
<para>To free up resources, you will need to clean up by running
|
|
<command>dosetupnode</command> on each client machine. For example,
|
|
in &man.csh.1;:
|
|
<screen>&prompt.user; <userinput>cd ~/loads; foreach i (*); /var/portbuild/scripts/dosetupnode i386 5-exp $i -norsync &; done</userinput></screen>
|
|
|
|
The <literal>-norsync</literal> says not to bother resyncing the
|
|
entire build data (ports tree, etc) on any remote machines, and it
|
|
will just clean up old <literal>chroot</literal>s and then reset the
|
|
build queue for that machine.</para>
|
|
|
|
<para>If you forget to do this, then the old build
|
|
<literal>chroot</literal>s will not be cleaned up for 24 hours, and no
|
|
new jobs will be dispatched in their place since
|
|
<hostid>pointyhat</hostid> thinks the job slot is still occupied.</para>
|
|
|
|
<para>To check, <command>cat ~/loads/*</command> to display the
|
|
status of client machines; the first column is the number of jobs
|
|
it thinks is running, and this should be roughly concordant
|
|
with the load average. <literal>loads</literal> is refreshed
|
|
every 2 minutes. If you do <command>ps x | grep pdispatch</command>
|
|
and it's less than the number of jobs that <literal>loads</literal>
|
|
thinks are in use, you're in trouble.</para>
|
|
|
|
<para>You may have problem with the <command>umount</command>
|
|
commands hanging. If so, you are going to have to use the
|
|
<command>allgohans</command> script to run an &man.ssh.1;
|
|
command across all clients for that buildenv. For example:
|
|
<screen>ssh -l root gohan24 df</screen>
|
|
|
|
will get you a df, and
|
|
|
|
<screen>allgohans "umount -f pointyhat.freebsd.org:/var/portbuild/i386/6-exp/ports"
|
|
allgohans "umount -f pointyhat.freebsd.org:/var/portbuild/i386/6-exp/src"</screen>
|
|
|
|
are supposed to get rid of the hanging mounts. You will have to
|
|
keep doing them since there can be multiple mounts.</para>
|
|
|
|
<note>
|
|
<para>Ignore the following:
|
|
|
|
<screen>umount: pointyhat.freebsd.org:/var/portbuild/i386/6-exp/ports: statfs: No such file or directory
|
|
umount: pointyhat.freebsd.org:/var/portbuild/i386/6-exp/ports: unknown file system

umount: Cleanup of /x/tmp/6-exp/chroot/53837/compat/linux/proc failed!
|
|
/x/tmp/6-exp/chroot/53837/compat/linux/proc: not a file system root directory</screen>

<title>Experimental Patches Builds</title>

<para>Experimental patches builds are run from time to time to

new features or bugfixes to the ports infrastructure (i.e.
|
|
<literal>bsd.port.mk</literal>), or to test large sweeping
|
|
upgrades. The current experimental patches branch is

<literal>6-exp</literal> on the &i386;

architecture. (For the moment, we are also using

|
<para>In general, an experimental patches build is run the same
|
|
way as any other build, except that you should first update the
|
|
ports tree to the latest version and then apply your patches.

|
To do the former, you can use the following:
|
|
|
|
<screen>&prompt.user; <userinput>cvs -R update -dP > update.out</userinput>

&prompt.user; <userinput>date > cvsdone</userinput></screen>

original copies of all changed files, as well as a list of what

<para>In order to have a good control case with which to compare

|
which the experimental patches branch is based for the &i386;
|
|
architecture (currently this is <literal>6</literal>). Then, when
|
|
preparing for the experimental patches build, checkout a ports

down, package client error, etc.)

<para>Both columns should be investigated and the reason for the
|

errors understood before committing the experimental patches set.

|
To differentiate between [1] and [2] above, you can do a rebuild
|
|
of the affected packages under the control branch:</para>
|
|
|
|
<screen>&prompt.user; <userinput>cd /var/portbuild/i386/6/ports</userinput></screen>
|
|
|
|
<note><para>Be sure to <literal>cvs update</literal> this tree to the same date as
|
|
the experimental patches tree.</para></note>
|
|
|
|
<para>The following command will set up the control branch for
|
|
the partial build:</para>
|
|
|
|
<screen>&prompt.user; <userinput>/var/portbuild/scripts/dopackages.6 -noportscvs -nobuild -nocvs -nofinish</userinput></screen>
|
|
|
|
<para>The builds must be performed from the
|
|
<literal>packages/All</literal> directory. This directory should
|
|
initially be empty except for the Makefile symlink. If this
|
|
symlink does not exist, it must be created:</para>
|
|
|
|
<screen>&prompt.user; <userinput>cd /var/portbuild/i386/6/packages/All</userinput>
|
|
&prompt.user; <userinput>ln -sf ../../Makefile .</userinput>
|
|
&prompt.user; <userinput>make -k -j<#> <list of packages to build></userinput></screen>
|
|
|
|
<note><para><#> is the concurrency of the build to
|
|
attempt. It is usually the sum of the weights listed in
|
|
<filename>/var/portbuild/i386/mlist</filename> unless you have a
|
|
reason to run a heavier or lighter build.</para>
|
|
|
|
<para>The list of packages to build should be a list of package
|
|
names (including versions) as they appear in
|
|
<filename>INDEX</filename>. The <literal>PKGSUFFIX</literal>
|
|
(i.e. .tgz or .tbz) is optional.</para></note>
|
|
|
|
<para>This will build only those packages listed as well as all
|
|
of their dependencies.</para>
|
|
|
|
<para>You can check the progress of this
|
|
partial build the same way you would a regular build.</para>
|
|
|
|
<para>Once all
|
|
the errors have been resolved, you can commit the package set.
|
|
After committing, it is customary to send a <literal>HEADS
|
|
UP</literal> email to <ulink
|
|
url="mailto:ports@FreeBSD.org">ports@FreeBSD.org</ulink> and
|
|
copy <ulink
|
|
url="mailto:ports-developers@FreeBSD.org">ports-developers@FreeBSD.org</ulink>
|
|
informing people of the changes. A summary of all changes
|
|
should also be committed to
|
|
<filename>/usr/ports/CHANGES</filename>.</para>
