In bug 434746 it has been suggested that ${WORKDIR} should look like a
bzr branch or checkout. Proposed changes for bzr.eclass are included
below, comprising the following:
- bzr_fetch can optionally call bzr checkout --lightweight instead of
bzr export. The default behaviour won't change, the new behaviour
can be enabled with:
- New variable EBZR_WORKDIR_CHECKOUT, (Or can anyone come up with a
better/shorter name?)
- New variable EBZR_CHECKOUT_CMD.
- The sandbox environment is now always restored; before it was only
restored if ${EBZR_STORE_DIR} didn't exist. This is to prevent the
package's build system from writing to ${EBZR_STORE_DIR} when it's
calling bzr (which wasn't an issue for an export, but could be for
a checkout).
- Unrelated to the above, some old cleanup code (around line 220) is
removed.
The updated bzr.eclass is available in the emacs overlay, along with
an app-editors/emacs-vcs ebuild that I've used for testing.
