Amazing!, thanks for this.

Can you please comment on this?
Do you only need changes fixing the two bug you reported (which seem
easy at first glance) or something more substantial? In the latter
case, can you please file a bug report about that too?

Cheers.

edos-distcheck instead of AutoDepwait

[Joachim Breitner]

Hi,

today in the bus, I revived the idea of using edos-debcheck within
wanna-build to see whether a source package is installable on a given
architecture. I started to work on it, and a first preliminary version
is ready. You can have a look at it on
http://git.debian.org/?p=users/nomeata/wanna-build.git;a=shortlog;h=refs/heads/edos-debcheck

These changes introduce a new state, "DB-Uninstallable", which indicates
that the build-dependencies can not be satisfied. Upon each call to
--merge-all (which happens regularly, right?), packages in the states
Needs-Build and BD-Uninstallable will be checked for the installability
of their build-dependencies. The reason is stored as well (edos-debcheck
_does_ give reasons for uninstallable).

It needs a slightly modified version of edos-builddepends, called
wb-edos-builddepends. These changes can probably be merged upstream and
enabled with a flag. To test it, you need to symlink this binary
to /usr/local/bin, as wanna-build sets a static PATH (or change that).


I also started (as you saw) a little testscript to reproducible test
wanna-builds behaviour in a clean environment. It uses some perl hackery
to make it use a different configuration file, and only touches files
in ./tests/tmp. The state in the master branch only tests the current
Auto-Dep-Waits code (which I then replaced), but of course it can be
extended. The version in the master branch can be merged independently
from the edos-feature.


I’d be grateful if you could give early feedback, so that I don’t
program in a direction that will not be acceptable by you.

Greetings,
Joachim


BTW:
I based my work on the version of edos-debcheck in unstable.
Additionally, I filed two bugs against edos-distcheck that should be
fixed before starting to use it, although they are not really critical:
