| == Description ==
| |
| <!-- Put a description of the task here.
| |
| -->
| |
| At each alpha freeze we branch the pending release away from devel/ which allows rawhide to move on while the pending release goes into bugfix and polish mode.
| |
|
| |
| == Action ==
| |
|
| |
| === PackageDB ===
| |
|
| |
| Mass branching in the pkgdb is the first step. It should be done near the time that the scm branches are created so as not to confuse packagers. However, it does not cause an outage so it should be done ahead of time.
| |
|
| |
| First, someone needs to add the new release to the PackageDB. [[ISOP:PKGDB#Add a new release| See this section]]
| |
|
| |
| Then a scmadmin needs to either start the mass branching process from the command line or by pushing a button on a web page. The web page method is to browse to https://admin.fedoraproject.org/pkgdb/collections/ login, and then click the "Branch All" button.
| |
|
| |
| The command line method is to run:
| |
| <pre>
| |
| pkgdb-client mass-branch -b F-13
| |
| </pre>
| |
|
| |
| Whichever method you choose, the command will start the mass branch process on the server and then return with a message that the branching is in progress.
| |
|
| |
| When the branching is finished, you will receive an email that tells you of any unbranched packages as well as all the packages that were branched.
| |
|
| |
| If something fails spectacularly, it is safe to try mass branching again at a later time. If only a few cleanups a re needed it might be better to do that with the regular branch commands.
| |
|
| |
| {{admon/warning|Target pkgdb-client against bapp01| At present there is a bug in the mass branching code so that the branching seems to work but the changes aren't saved in the database. I think this occurs when the server handles other requests while the packagedb is processing a mass branch. Performing the mass branch on bapp1 which is not handling other requests while the mass branch is occurring is one way to work around this. It's likely a bug in how forking in the mass branch code is interacting with the database connections.
| |
|
| |
| Retarget pkgdb-client to use bapp1 by changing the value of pkgdb.url in either /etc/pkgdb-client.cfg or ~/.fedora/pkgdb-client.cfg.
| |
|
| |
| <pre>
| |
| [global]
| |
| pkgdb.url = "http://bapp01/pkgdb/"
| |
| </pre>
| |
| }}
| |
|
| |
| === Puppet ===
| |
|
| |
| A couple files under puppet management need to be updated to be aware of a new branch.
| |
|
| |
| ==== pkgdb2branch.py ====
| |
|
| |
| This file is used by an scmadmin to read data from pkgdb and create branches in the source control. Two parts need to be updated, one part that defines valid branches and what existing branch to create them from, and the other part defines a mapping of branch names in pkgdb to branch names in scm.
| |
|
| |
| On the puppet server in a clone edit the modules/gitolite/files/distgit/pkgdb2branch.py file:
| |
|
| |
| <pre>
| |
| diff --git a/modules/gitolite/files/distgit/pkgdb2branch.py b/modules/gitolite/file

| ==== genacls.pkgdb ====
| |
|
| |
| The other file is ran by cron that will read data out of pkgdb and construct an ACL config file for our scm. It has a section that lists active branches to deal with as pkgdb will provide data for all branches.

| |

| |
|
| |
| ==== Push the changes ====
| |
|
| |
| When done editing the files, commit and push them, then restart puppet on the scm server in order to get the new files in place.
| |
|
| |
| === SCM ===
| |
|
| |
| The following work is performed on pkgs01
| |
|
| |
| ==== Make git branches ====
| |
| Run pkgdb2branch.py to branch the repos on the scm server. The --branch-for option was designed with this use case in mind::
| |
| <pre>
| |
| ./pkgdb2branch.py --branch-for=f15
| |
| </pre>
| |
|
| |
| If for some reason that doesn't work, you can try this alternative:
| |
| <pre>
| |
| cat pkglist.txt|./pkgdb2branch.py -c -
| |
| </pre>
| |
| where pkglist.txt is a list of all the packages to branch.
| |
|
| |
| ==== Update ACLs ====
| |
|
| |
| Although cron may have run, it is smart to manually run the cron job to make sure new ACLs are in place:
| |
|
| |
| <pre>
| |
| $ sudo -u jkeating /usr/local/bin/genacls.sh
| |
| </pre>
| |
|
| |
| === Update preupgrade releases.txt ===
| |
| File a [https://fedorahosted.org/fedora-infrastructure ticket with Infrastructure] to modify the mirrors/releases.txt file to include pointers to the new release, for use by preupgrade. This file is in the [http://git.fedorahosted.org/git/?p=fedora-web.git;a=summary fedora-web git repo.]
| |
| You will need to add something like:
| |
|
| |
| <pre>
| |
| [Fedora N ($codename)]
| |
| stable=False
| |
| preupgrade-ok=True
| |
| version=N
| |
| mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-N&arch=$basearch
| |
| installmirrorlist=http://mirrors.fedoraproject.org/mirrorlist?path=pub/fedora/linux/development/N/Fedora/$basearch/os/
| |
| </pre>
| |
|
| |
| === Update AutoQA repoinfo.conf ===
| |
| The [[AutoQA]] project maintains a config file ({{filename|repoinfo.conf}}) that describes available package repositories and their inheritance. In order to have automated testing of Branched package builds, the {{filename|repoinfo.conf}} file needs to be updated. Please [https://fedorahosted.org/autoqa/newticket?summary=Update%20repoinfo.conf%20-%20Add%20branch&type=task&component=production&priority=critical&milestone=Hot%20issues file an autoqa ticket] to modify the {{filename|repoinfo.conf}} file to include pointers to the new release.
| |
|
| |
| === Koji ===
| |
| The koji build system needs to have some tag/target work done to handle builds from the new branch and to update where builds from master go. See the [[Adding_Build_Targets_SOP#Koji|section on Koji in the Adding Build Targets SOP]] for details.
| |
|
| |
| === Fedora Release ===
| |
| The Fedora release package needs to be updated in both the new branch and in master. '''FIXME Link to fedora release bump SOP'''
| |
|
| |
| === Bodhi ===
| |
| Bodhi needs to be turned on for the new branch. Instructions in the [[Bodhi_Infrastructure_SOP|Bodhi SOP]]
| |
|
| |
| === Enable nightly branched compose ===
| |
| A cron job needs to be modified and turned on for the new branch. '''FIXME Link to nightly branched SOP'''
| |
|
| |
| === Update kickstart used by nightly live ISOs ===
| |
|
| |
| On a nightly basis, a live ISO image is created for each [http://spins.fedoraproject.org spin] and hosted at http://alt.fedoraproject.org/pub/alt/nightly-composes. The yum repositories used by [https://fedorahosted.org/spin-kickstarts/ spin-kickstarts] need to be updated to use the branched repository. Please [https://fedorahosted.org/rel-eng/newticket?summary=Update%20nightly%20spin%20kickstart&type=task&component=production&priority=critical&milestone=Hot%20issues&cc=kevin file a rel-eng ticket] to request updating the kickstart file used to generate the nightly spin ISO's.
| |
|
| |
| === Comps ===
| |
| A new comps file needs to be created for the next fedora release (the one after what we just branched for). '''FIXME Link to comps SOP'''
| |
|
| |
| === Mock ===
| |
| Mock needs to be updated to have configs for the new branch. This should actually be done and pushed just before the branch event. '''FIXME Link to mock update SOP'''
| |
|
| |
| === MirrorManager ===
| |
| Mirror manager will have to be updated so that the yum repo redirections are going to the right places. '''FIXME Link to MM SOP'''

| == Getting a List of Unbranched Packages ==
| |
|
| |
| After mass branching you may want to run sanity checks to see if there were packages that weren't successfully branched. There's a script on the cvs server that can help you do this. The script needs to be run first on the cvs server and then on a machine with the kojiclient libraries installed (your local workstation should be fine.).
| |
|
| |
| <pre>
| |
| On cvs1:
| |
| CVSROOT=/pkgs/cvs cvs co CVSROOT
| |
| CVSROOT/admin/find-unbranched cvs F-12 > unbranched
| |
|
| |
| On your workstation:
| |
| scp cvs1.fedoraproject.org:CVSROOT/admin/find-unbranched .
| |
| scp cvs1.fedoraproject.org:unbranched .
| |
| ./find-unbranched compare F-12 unbranched
| |
| </pre>
