pdebuild host --debbuildopts inherited by target pbuild

[TJ]

Binary package hint: pbuilder

This is a latent bug, exposed as a by-product of the fix I created for bug #278213 "Does not accept multiple --debbuildopts options" which resulted in "pbuilder (0.181ubuntu6)".

The problem is that when using pdebuilder and passing --debbuildopts to both 'sides' (host and target), the target pbuilder dpkg-source incorrectly inherits the host --debbuildopts.

For example:

 HOST_DEB_OPTIONS="--debbuildopts -i -I"
 PBUILDER_DEB_OPTIONS="--debbuildopts -Idebian/dpkg-source.excludes"
 pdebuild --logfile $LOGNAME ${HOST_DEB_OPTIONS} -- ${PBUILDER_DEB_OPTIONS}

results in the inner dpkg-source seeing:

 dpkg-source -i -I -Idebian/dpkg-source.excludes -b kvm-83+dfsg

Which in Hardy and later isn't a problem (since -I is acceptable to dpkg-source >= v1.14.7). However, if working on back-porting a package to Gutsy or Feisty or Edgy the versions of dpkg-source in those releases do not understand the -I option without a file specification (-I<exclusion.list>).

This will cause the target pbuild to fail since the source can't be extracted.

This wouldn't have come to light if it wasn't for my desire to back-port some packages for use on long-lived servers that are running stable older releases. In these cases my build_test script generates two different sets of --debbuildopts for the host (more recent) and target (older) dpkg-source.

The builds were failing and as can be seen in the example above it is because the host's --debbuildopts are passing to the target.

Patches to follow.

It would be helpful to backport this change to Intrepid and Hardy since they have received automated backports of the recent Jaunty package.

Could you try with the latest pbuilder, 0.196? It supports resetting the debbuildopts, but still works as before for the default case.

So you would use:
pdebuild --debbuildopts foo
to pass foo to both host and guest and:
pdebuild --debbuildopts foo -- --debbuildopts "" --debbuildopts bar
to pass foo to host and bar to guest and
pdebuild -- --debbuildopts bar
to pass nothing to host and bar to guest.

Let me know if that fixes the bug for you.

As asked before: It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 326216 and any other logs that are relevant for this particular issue.
