The art of releasing
This is a template on how to do a release.
On crater branch the repo:
cd /repository/git/dragonfly.git git branch DragonFly_RELEASE_x_y (e.g. 2_8)
This is the only step that needs to happen remotely.
On your own system:
Check out two copies of /usr/src, one with master checked out, one with the new release branch checked out. Checkouts should be under your user id, NOT as root, or the later tagging operation will be unhappy.
mkdir master cd master git init git remote add origin ssh://crater.dragonflybsd.org/repository/git/dragonfly.git git fetch origin cd .. cp -R master x_y # x_y is the release; faster than rechecking out cd master git checkout master cd ../x_y/ git branch DragonFly_RELEASE_x_y origin/DragonFly_RELEASE_x_y git checkout DragonFly_RELEASE_x_y
On the new branch:
Edit __DragonFly_version and related comments. You only need to add a commented version number for the branch, not the new master.
Edit BRANCH, use 'RELEASE', update version. e.g. RELEASE_2_8
In the "Default .Os value" section, bump up the version to that of the release (even minor number).
Adjust the default src checkout in /usr/src/etc/Makefile.usr to pull this branch. Otherwise, anyone using the Makefile to download source will get master, and nrelease will build master.
Update OSNAME for mdocml:
Edit __DragonFly_version and related comments. Put in commented numbers for the new release and master.
Edit BRANCH, use 'DEVELOPMENT', update version.
In the "Default .Os value" section, bump up the version to that of the master (odd minor number). Additionally, in the "DragonFly releases not found in doc-common" section, add a new line (a la the previous ones) for the new master.
Update OSNAME for mdocml:
Before you tag, make sure there aren't any last minute surprises - build this new branch, current version, whatever.
Make sure all changes on the master branch and on the new branch have been committed and pushed before tagging anything.
git add sys/sys/param.h sys/conf/newvers.sh gnu/usr.bin/groff/tmac/mdoc.local etc/Makefile.usr contrib/mdocml/config.h git commit git push
git add sys/sys/param.h sys/conf/newvers.sh gnu/usr.bin/groff/tmac/mdoc.local contrib/mdocml/config.h git commit git push
man git-tag for info, the committer needs GPG set up so git tag -s works. Then you can use your own checkout. Be sure the checkouts are under your user id and you do the tagging as yourself instead of as root.
You may need to set GPG_TTY to get GPG to work if it tries to run pinentry-curses. This is the line for bash, since that's quoted most often for this fix.
setenv GPG_TTY $tty
git tag -s -m "DragonFly x.x.0" vx.x.0 git push --tags
In the new branch
git tag -s -m "DragonFly x.y.0rc" vx.y.0rc git push --tags
Do the x.x.0rc immediately. Just before doing the final nrelease build roll a x.x.0 tag for the release branch - the same method, just without "rc" for release candidate. Release as x.x.0.
A new tag may require a commit beforehand to the release branch to make sure it goes to the right branch.
Subsequent tag updates
When updating a x.x.1 version, you just need to tag.
If there's a significant change between versions - major library change or third-party software update, which is more likely in the development branch of DragonFly - update param.h
Generally, any files not specifically mentioned above as specific to a branch should be updated in master and then cherry-picked to the release branch. src/UPDATING is the most common example.
Adjust the default pkg checkout in /usr/src/etc/Makefile.usr for both master and the new branch if necessary.
dports for the new release should be built before announcing, so that people testing the release, or a release candidate, can install with immediately available packages.
Build isos and imgs
Make sure there's an appropriate dports path for pkg to download from when building images - especially release candidates. When there is a major version change, the packages for master will not be named correctly. (i.e. going from 3.8 to 4.0 means that the master packages were in 3.10, and the directory arrangement will reflect that). Tag, get packages built, then create initial ISO/IMG files.
Set DPORTS_PATH when building the image to pick where dports comes from. Ideally, there should be a release tag in dports that corresponds with the DragonFly release.
git fetch --tags git checkout TAGNAME
If your ISO is too big for a normal CD, try stripping modules. Make sure to use a blank make.conf so local changes don't interfere. Here's the "final" string:
make -DINSTALLSTRIPPEDMODULES DPORTS_PATH=/the/path __MAKE_CONF=/dev/null release
To build it. (add pkg/gui/whatever targets as necessary.)
Testing should be done on real hardware, qemu and vmware. We have six isos/imgs that needs testing.
i386 iso, img, gui-img
x86_64 iso, img, gui-img
- Booting install media.
- Installing; encrypted, unencrypted, ufs, hammer.
- Configuring everything in the installer; try both dhcp and static IP.
- Booting the installed system.
Copy one of the existing release pages. The general format is :
- General announcement
- Big items new to this release
- Availability, describing what can be run
- MD5 results for compressed and uncompressed files
- Special notes and caveats
- Release notes - go through git log for these.
Complete, or at least mostly complete, before announcing any versions.
- Update the release page, the main page, and the general Download page.
- Add new MD5 sums on the release page for the compressed and uncompressed files.
Place images in /ftp/iso-images on crater.dragonflybsd.org. They will be rsynced to mirror-master.
The file md5.txt should have the md5 output for all the compressed files. It should also have the md5 output for the uncompressed images, so don't just 'md5 *bz2 > md5.txt'; get that separately and copy it into the document.
/root/adm/domd5.sh will get the MD5 sums for the compressed and uncompressed images and print them to stdout. The script will run faster if you edit it to only check the new files, and then manually add the lines to md5.txt.
A BitTorrent setup would be desirable, but there's no standard process for it as part of release, yet.
