Creating a branch:

Cutting release candidates and releases:

  1. Make sure release notes are updated in distrib/notes

    A good starting point is to generate notes for a sample port (cd distrib/notes/amd64; make USETOOLS=no), read the HTML file, and look for things that need updating.

    Stuff you'll definitely need to do:

    • Brace yourself. The sheer amount of useless information from days of yore will blow you away. You'll even start to think "you know, it's possible someone actually does want to read about splitting distribution sets so they'll fit on floppies."
    • Update Dd (should be the day the release is tagged)
    • Update version numbers
    • Add mention of the latest CHANGES-<version> file in the "Release Contents" section
    • List changes present in this release
    • Adjust known issues section as necessary
    • Adjust compatibility issues section as necessary
    • Check the {core,portmasters,releng,developers} lists (while grumbling about how you really ought to just remove this ridiculous self-indulgent section from the notes entirely).

    Note: the "changes" part of this should be taken from an mdoc file that is generated from htdocs/releases/formal-<BLAH>/changes<VERSION>.xml. Look for ".Ss Changes Between the NetBSD" in distrib/notes/common/main and paste away! You may have to make a few markup changes to the contents of the mdoc file, because the XML -> mdoc converter sucks. Always check to make sure things are formatted as intended.

    Basically, in htdocs/releases/formal-<blah>, copy the previous release's XML files, adjust Makefile as necessary, and start the dull process of adding content. Beware that this is a soul-sucking task, and you MUST RESIST THE TEMPTATION TO MENTION EVERY LITTLE CHANGE. Try to keep it to a list of things that people will be excited about and will sell NetBSD. Release notes != changelog.

    Don't forget to edit htdocs/layout.xml and add an entry for the new page.

  2. Update version numbers in gnu/usr.bin/groff/tmac/mdoc.local and sys/sys/param.h. Add new CHANGES file to doc/README.files, updating release numbers while there. Make sure doc/LAST_MINUTE is zeroed out and adjust version number.

  3. Note changes from steps 1 and 2 in doc/CHANGES-<whatever>

  4. cvs -f rtag -a -rnetbsd-5 netbsd-5-0-RELEASE src xsrc

    If something needs to be retagged after the fact:

    • Change <file> on the netbsd-5 branch.
    • cvs tag -d netbsd-5-0-RELEASE <file>
    • cvs tag -rnetbsd-5 netbsd-5-0-RELEASE <file>
  5. Add tag (netbsd-5-0-RELEASE) to ~builds/etc/archlist on build.netbsd.org Add tag to AB_STICKY_TAG_LIST in ~builds/etc/autobuild.conf. Note that these files are revision controlled (localsrc/releng/autobuild/etc), so the proper order is to commit your changes in localsrc and then cvs up (it pulls from anoncvs@nbcvs) on build.netbsd.org.

  6. Add tag to ~builds/etc/build_order like: netbsd-5-0-RELEASE:N:N This means the tag will only be built once, and it won't be uploaded after it finishes building. Put it at the top. You'll have to kill run_builds.sh and restart the builds to get this to take effect, or you could insert it after the top line and it will be the next build (which doesn't require killing run_builds.sh.

  7. Spend the next few hours worrying about some unforeseen or sporadic problem causing one or more ports to fail. Cross your fingers and hope that you're spared the hassle. If you're not so lucky, dig around and manually rebuild a port on one of b[678], copying the build.sh line from logs, mainly to preserve the -B flag's argument. Copy the results back to build.netbsd.org and proceed.

  8. Create ISOs (macppc, mac68k, source). See below for instructions. Create hashes for ISOs (cksum -a sha512 NetBSD* > SHA512)

  9. rsync to nbftp. It goes to a staging dir in /pub/NetBSD/misc/releng first.

     rsync -avu --progress --port 874 --password-file /home/builds/.rsync &lt;path-to-top-level-release-dir&gt; builds@ftp.netbsd.org::builds/
    

    This will upload the files to ftp.NetBSD.org:/pub/NetBSD/misc/releng/. After that, get admins to create /pub/NetBSD/NetBSD-<release> and /pub/NetBSD/iso/<release> directories for you, owned by builds:builds. Once these have been made, move images/* to the iso directory and symlink to "iso" and "images" in the main release directory, and move the rest to the main release directory.

  10. create torrents

    In the images directory:

    for i in NetBSD-* ; do
    maketorrent-console http://tracker.netbsd.org:6969/announce $i
    done
    
  11. Get admins@ to add the torrent directory to ~torrent/runbt.
    NOTE FROM SPZ, 2010-11-15:

    it turns out that bittorrent can't do more than one 'allowed_dir'.

    Thus, we now have /ftp/pub/NetBSD/torrent. Please keep the permissions so that mirrors can't read the contents, since the contents are duplicate.

    (This should go into releng docs probably:) If you add a file that should be picked up by torrents, put it and its torrent control file where it belongs and hard-link the two into the appropriate directory in the torrent tree. Please note that the torrent tree cannot be used to publish the torrent control file via http or ftp.

  12. Get security-officer@ to sign binaries and ISOs. localsrc/security/programs/rel-hashes.sh

  13. Give mirror-maintainers a heads up that new release binaries are available. This should be done 3ish days prior to the expected announce date.

  14. Have admins update sup. Wonder if anyone still uses sup anyway.

  15. Update the website.

    • Commit release's HTML file in htdocs/releases/formal-<blah>
    • Update htdocs/share/xml/misc.ent (release.*)
    • Add htdocs/support/security/patches-<blah>
    • Update htdocs/support/security/index.xml
    • Update htdocs/support/security/release.xml
    • Update htdocs/releases/formal-<blah>/index.xml
    • Update htdocs/mirrors/torrents/
    • Update htdocs/releases/formal.xml
    • Top-level regen of everything
    • Update htdocs/changes/index.xml
    • Update htdocs/index.html
    • Port pages in wikisrc -- sed? :\ (don't bother with xen)
    • Update htdocs/developers/features/
    • Update htdocs/docs/guide/en/chap-fetch.xml
  16. Update /pub/NetBSD/README to mention the new release

  17. Announce the release on netbsd-announce@ and the blog.


BUILDING ISOs

The following stuff should be done on build.netbsd.org as the 'builds' user.

Images that need to be built manually: macppc, mac68k, source

Needs to be cdrtools 2.01 (but not newer!). The binary in ~/bin/mkisofs will work.

    cd ~/scratch
    tar xzvpf /home/builds/ab/HEAD/ab-src.tgz (note -- "HEAD" is always used)

Building in src/distrib/cdrom:

Copy and fiddle with some ridiculous .mk and .conf files, adjusting for the relevant release.

Do the following three times, changing TARGET_CD_IMAGE to macppccd, mac68kcd, and sourcecd.

    make MKISOFS=/home/builds/bin/mkisofs USETOOLS=no RELEASE=5.0 TARGET_CD_IMAGE=macppccd DISTRIBDIR=/home/builds/ab/netbsd-5-0-RC4/release/netbsd-5-0-RC4/200904142015Z all

post-release:

create netbsd-5-0 branch:

    cvs rtag -a -b -rnetbsd-5 netbsd-5-0 src xsrc
