Hi,

I would like to use a customized cowbuilder image when running git-buildpackage.
If I try to pass the location of this image to --git-pbuilder-options, git-buildpackage
continues using base.cow instead of the file I want to use.

The command I use is the following, where mybase.cow is the image I want to use:

$ git-buildpackage --git-ignore-new --git-pbuilder --git-pbuilder-options='--basepath /var/cache/pbuilder/mybase.cow'

Thanks!

git-pbuilder doesn't take options to change the basepath.  Instead, it
uses environment variables.  See the git-pbuilder man page for more
information, but the short version is that you want:

    env DIST=mybase git-buildpackage --git-ignore-new --git-pbuilder

Options passed to git-pbuilder are just passed directly on to debbuild.

This command is still not working for me :-(

According to git-pbuilder man page, I must retitle mybase.cow to
base-mybase.cow. When I retitle the image, git-pbuilder works using this
command:

$ env DIST=xmlstarlet git-pbuilder

but if I run git-buildpackage with the command you recommended, it still
continues using base.cow.

I've taken a look to the source code and it seems that DIST env var is
overwritten when using --git-pbuilder option [0]:

    if options.use_pbuilder or options.use_qemubuilder:
        ...
        os.environ['DIST'] = options.pbuilder_dist

Thanks for your help,

Ah, yes, sorry, that's true.  The base directory must begin with "base-"
currently.

Oh, sorry, I'd missed that.  So if you're using --git-pbuilder, you
instead want --git-dist=mybase.  But you will have to name it with "base-"
as a prefix.

with the following command, it works:

$ git-buildpackage --git-pbuilder --git-dist='mybase'

But I still think that this solution is not very intuitive (or my
intuition is not good enough ;-) ), so I'll keep this bug open. I think
it's more intuitive to pass the option to --git-pbuilder-options or have
an option with a more intuitive name.

Thanks again!
