The name suggests that it is supposed to substitute a variable with a
value, but we tend to use it in a more liberal replace_all() fashion,
but this breaks if either of the parameters is empty or more importantly
if two "variable" occurrences follow each other directly.
APT's cache can include packages from architectures dpkg has no
knowledge about and can therefore not be installed for e.g. to allow
easy lookups. There is no point in telling external solvers about them
though and some of them might even be really talkative about ignoring
them if we do.
In commit 21b3eac8 I promoted the check for installable dependencies to
a pre-install check, which also reverts to a known good candidate (the
installed version) if it fails. This revert was done even for user
requested candidate switches which disabled our Broken detection so that
install requests which are impossible to satisfy do not fail anymore,
but print an (incomplete) solution proposal and then exit successfully.

This will show the same unauthenticated warning for source packages
as for binary packages and will not download a source package if
it is unauthenticated. This can be overridden with
--allow-unauthenticated

EDSP code uses pipes opened via an FD as sources and later for those
files modification times and filesize are read - but never really used
again. The result we get from FileFd is probably wrong, but as we don't
use it anyway, we just don't fallback if we have nothing to fallback to

Solvers are supposed to exit successfully even if they haven't found a
solution, but a solver which fails drastically (like e.g. segfaults)
should be detected and dealt with accordingly instead of ignored.
This can happen if the request is already a well-formed request all by
itself (e.g. the package has no dependencies), but the resolver found
a reason to not accept it as solution. Our edsp 'dump' solver e.g.
shouldn't be able to trigger install, which it does otherwise.
dpkg on Ubuntu 12.04 does not seem to support parsing arch-specific
dependencies, so we try to detect if we face such a dpkg in the test.
In the other test the order depends on libdb, which changes per arch, so
we just run it through our sorting binary and be happy (hopefully).
