3 This package is maintained in Git via the Alioth pkg-k5-afs project.
4 Alioth is used only for repository access control and not for any of
7 Since we often pull up many upstream fixes from the upstream stable
8 branch due to slow upstream release frequencies, we use Git to handle
9 merging and patch pullups and do not attempt to export the Git
10 repository state as a patch set. This package uses 3.0 (quilt) via
11 the gbp pq subcommands.
13 Ideally, any changes that are not strictly Debian packaging changes
14 should be submitted upstream first. Upstream uses Gerrit for patch
15 review, which makes it very easy for anyone who wishes to submit
16 patches for review using Git. See:
18 http://wiki.openafs.org/AFSLore/GitDevelopers
20 for information on how to submit patches upstream. Starting from
21 OpenAFS 1.5, we're no longer carrying any substantial Debian-specific
22 changes outside of the debian/* directory, only temporary bug
23 workarounds, and we want to keep it that way.
25 Importing a New Upstream Release
27 We want to be able to use Git to cherry-pick fixes from upstream, but
28 we want to base the Debian packages on the upstream tarball releases.
29 We also need to strip some non-DFSG files from the upstream tarball
30 releases and imported code, and want to drop the WINNT directory to
31 save some space. This means we follow a slightly complicated method
32 for importing a new upstream release.
34 Follow the following procedure to import a new upstream release:
36 1. Update the package version in debian/changelog to match the new
37 upstream version. If the new upstream version is a prerelease
38 version, don't forget to add "~" before "pre" so that the versions
41 2. Double-check the TAG setting in debian/rules to be sure it's going
42 to retrieve the correct Git tag.
44 3. Run debian/rules get-orig-source. This will generate a tarball
45 from the upstream Git tag using git archive, remove the WINNT
46 directory, and create a file named openafs_<version>.orig.tar.xz in
47 the current directory.
49 4. Ensure that you have the OpenAFS upstream Git repository available
50 as a remote in the Git repository where you're doing the packaging
51 work and it's up to date:
53 git remote add openafs git://git.openafs.org/openafs.git
56 This will be required to locate the tag for the new upstream
59 5. Determine the release tag corresponding to this tarball. At the
60 time of this writing, upstream uses tags in the form:
62 openafs-stable-<version>
63 openafs-devel-<version>
65 for stable and development releases respectively. <version> is the
66 version number with periods replaced by underscores. This
67 convention may change, so double-check with git tag.
69 6. Import the upstream source from the tarball with:
71 gbp import-orig --upstream-vcs-tag <tag> <tarball>
73 where <tarball> is the tarball created by get-orig-source above and
74 <tag> is the corresponding tag from the upstream Git repository.
76 7. Flesh out the changelog entry for the new version with a summary of
77 what changed in that release, and continue as normal with Debian
80 Pulling Upstream Changes
82 Upstream releases, particularly stable releases, are relatively
83 infrequent, so it's often desirable to pull upstream changes from the
84 stable branch into the Debian package. This should always be done
85 using git cherry-pick -x so that we can use git cherry to see which
86 changes on the stable branch have not been picked up.
88 The procedure is therefore:
90 0. Regenerate and switch to the patch-queue branch with
91 git branch -d patch-queue/master && gbp pq import
93 1. Identify the hash of the commit that you want to pull up using git
94 log or other information.
96 2. git cherry-pick -x <hash>. If the cherry-pick fails and you have
97 to manually do a merge, follow the instructions to use -c to keep
98 the original commit message as a starting point, but *also*
99 manually add a line like:
101 (cherry picked from commit <hash>)
103 to the changelog entry where <hash> is the full hash of the
104 upstream commit. Note that the upstream commits on the stable
105 branch will generally already have a line like this from upstream's
106 cherry-pick. This will be a second line.
108 3. Switch to the master branch and (re)generate patch files:
109 git checkout master && gbp pq export
111 4. Add a changelog entry and commit it along with the added patch files.
112 Use the following convention for changelog entries for cherry-picks:
114 * Apply upstream deltas:
118 where <hash> is the first eight characters of the upstream commit
119 hash and <title> is the first line of the upstream commit message,
120 edited as necessary to keep the length of the changelog lines
