Importing SourcesImporting already existing &debian; packagesImporting an already exsting debian package into a git repository is as easy as:
&git-import-dsc; package_0.1-1.dsc
This will create a new git repository named after the imported package, put
the upstream sources onto the and the
debian patch on the . In case of a debian
native package only the is being used.
You can specify alternative branch names via the
and
options or via the and
options in the configuration file.
If you want to import further versions you can change into your shiny new
&git; repository and just continue with the same command:
cd package/
&git-import-dsc; package_0.1-2.dsc
&git-import-dsc; package_0.1-3.dsc
&git-import-dsc; package_0.2-1.dsc
Or you can import all versions at once using &git-import-dscs;:
&git-import-dscs; /path/to/history/package_*.dsc
This will create a &git; repository if necessary and import all versions sorted
by version number.
Importing a new upstream versionChange into your git repository (which can be empty), make sure it
has all local modifications committed and run either of:
&git-import-orig; /path/to/package_0.2.orig.tar.gz
&git-import-orig; /path/to/package_0.2.tar.bz2
&git-import-orig; /path/to/package-0.2/
This puts the upstream souces onto the and
tags them accordingly (the default tag format is
upstream/<version>).
The result is then merged onto the
and a new &debian; changelog entry is created. You can again specify
different branch names via the and
options. You can also filter out content
you don't want imported:
&git-import-orig; ='CVS/*'/path/to/package_0.2.orig.tar.gz
The option can be used multiple times for more
complex filtering.
If you expect a merge conflict you can delay the merge to the
via the and pull in
the changes from the later.
Converting an existing &git; repository
If the &git; repository wasn't created with &git-import-dsc; you have to tell
&git-buildpackage; and friends where to find the upstream sources.
Upstream sources on a branch
If the upstream sources are already on a separate branch things are pretty
simple. You can either rename that branch to the default
name upstream with:
&gitcmd; branch upstream theupstream-branch
&gitcmd; branch theupstream-branch
or you can tell &git-buildpackage; the name of the branch to use as
:
cat <<EOF > .git/gbp.conf
[DEFAULT]
# this is the upstream-branch:
upstream-branch=theupstream-branch
EOF
If you then use &git-import-orig; to import new upstream sources, they will
from now on end up on theupstream-branch and
merged to the .
Upstream sources not on a branch
If you don't have an upstream branch but started your repository with only
the upstream sources (not the debian patch) you can simply branch from that
point. So use &gitkcmd; or &gitcmd;-log to locate the commit-id of that commit
and create the upstream branch from there, e.g.:
COMMIT_ID=`&gitcmd; log --pretty=oneline | tail -1 | awk '{ print $1 }'`
&gitcmd; branch upstream $COMMIT_ID
The important thing here is that the COMMIT_ID specifies a
point on the master branch that carried only the
upstream sources and not the debian modifications. The above example
assumes that this was the first commit to that repository.
There's currently no easy way to create the
if you never had the upstream sources
as a single commit. Using &git-import-orig; on such repositories might lead
to unexpected merge results.In order to fix this you can prepend the upstream sources as a
single commit to your tree using &git;'s grafts. Afterwards you
can simply create a branch as explained above and &git-import-orig; will
work as expected.Starting a Debian package from scratch
So far we assumed you already have a &debian; package to start with but
what if you want to start a new package? First create an empty repository:
mkdir package-0.1
cd package-0.1
git-initThen you import the upstream sources, branch off the
branch and add the debian files (e.g. via dh_make):
&git-import-orig; 0.1../package-0.1.tar.gz
&gitcmd; branch upstream
dh_make
That's it, you're done.
