UBUNTU: [Config] add debian/gbp.conf
Defines tag format for 'git buildpackage'.
More details about why I want to add this two-line config file
"debian/gbp.conf" to all the Ubuntu kernel branches:
[buildpackage]
debian-tag = Ubuntu-%(version)s
About git-buildpackage
----------------------
There exists a program called 'git-buildpackage'[0] (in an apt-get
package of the same name) which can drive the process of constructing a
Debian package from a git branch, including various pre-validation
steps, running debuild, and automatically adding a correct git tag
constructed from the version number in the changelog.
I have been using[1] git-buildpackage to construct the kernel packages
for upload (and actually a short wrapper script which implements some of
our additional Ubuntu-kernel-specific process steps).
Advantages of using git-buildpackage to do the package construction:
- Eliminates the very common human-error/typo mistakes that we
frequently make (incorrect git tags like forgetting to insert "-lts",
and generally inconsistent tag syntax).
- Makes the whole source package build process more consistent, and
allows for us to move towards even more consistency in the future.
Later, we might consider enabling more of git-buildpackages optional
validation steps, or even construct a package-build-bot.
- Its just a lot easier than trying to follow our complex wiki
instructions, which are mostly valid, but have lots of corner cases and
exceptions -- the places where we often make mistakes.
The two-line gbp.conf file
--------------------------
The purpose of the two-line gbp.conf file is simply to configure
git-buildpackage to create tags with our preferred git tag scheme, on a
per-branch basis. Specifically, the config file to be checked into the
main Ubuntu kernel branches will configure it to create tags of the
format:
Ubuntu-{versionextractedfromchangelog}
The next step will be that I will want to add a (different) two-line
gbp.conf file to all of our LTS branches, to configure them to be tagged
with:
Ubuntu-lts-{versionextractedfromchangelog}
Side note: Andy and I have experimented with additional debian/rules
bits that could use the same gbp.conf file in steps like "fdr
insertchanges". It could print out the correct git tag command for you
to cut-n-paste, as some of our other construction scripts do.
So this means that we now must use git-buildpackage???
------------------------------------------------------
No. See [1].
The presence of the gbp.conf file will affect nothing at all, unless you
choose[1] to use git-buildpackage.
You are welcome to keep using your preferred method of constructing
packages and git tagging, if that's what you prefer[1][1][1].
