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.

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).

As outlined in #748355 apt segfaulted if it encountered a loop between a
package pre-depending on a package conflicting with the previous as it
ended up in an endless loop trying to unpack 'the other package'.
In this specific case as an essential package is involved a lot of force
needs to be applied, but can also be caused by 'normal' tight loops and
highlights a problem in how we handle breaks which we want to avoid.
The fix comes in multiple entangled changes:
1. All Smart* calls are guarded with loop detection. Some already had it,
some had parts of it, some did it incorrect, and some didn't even try.
2. temporary removes to avoid a loop (which is done if a loop is
detected) prevent the unpack of this looping package (we tried to unpack
it to avoid the conflict/breaks, but due to a loop we couldn't, so we
remove/deconfigure it instead which means we can't unpack it now)
3. handle conflicts and breaks very similar instead of duplicating most
of the code. The only remaining difference is, as it should:
deconfigure is enough for breaks, for conflicts we need the big hammer

In bugreport #747261 I confirmed with this testcase that apt actually
supports the requested architecture-specific conflicts already since
2012 with commit cef094c2ec8214b2783a2ac3aa70cf835381eae1.
The old test only does simulations which are handy to check apt,
this one builds 'real' packages to see if dpkg agrees with us.

Version/Architecture information in a Translation-$lang file is
not allowed, so don't try to parse it. This is a fix for a bugreport
where a Translation-en file contained the content of the regular
Packages file (probably due to local FS corruption). This lead to
strange error messages on file download.
Thanks to Thomas Reusch for the report.

The bugreport highlights the problem with an empty package name. We fix
this by 'ignoring' these so that it behaves just like "apt-get install".
The deeper problem is that modifier strings can be longer than a package
name in which case the comparison doesn't make sense, so don't compare
then. Was not noticed so far as all modifiers are of length 1, so the
only package name shorter than this is in fact the empty package name.

My commit 45df0ad2 from 26. Nov 2009 had a little remark:
"The commit also includes a very very simple testapp."
This was never intended to be permanent, but as usually…
The commit adds the needed make magic to compile gtest statically
as it is required and links it against a small runner. All previous
testcase binaries are reimplemented in gtest and combined in this
runner. While most code is a 1:1 translation some had to be rewritten
like compareversion_test.cc, but the coverage remains the same.

fseek and co do this to their eof-flags and it is more logic this way as
we will usually seek away from the end (e.g. to re-read the file).
The commit also improves the testcase further and adds a test for the
binary compressor codepath (as gz, bzip2 and xz are handled by
libraries) via the use of 'rev' as a 'compressor'.

A package which can't be downloaded anymore is very likely dropped from
a release and can therefore no longer be 'standard' (or similar). We
therefore do not grant points for them anymore and demote them to
prio:extra instead which helps other packages breaking them away even if
they have a lower priority.
The testcase was initially created by Michael Vogt and just amended.

We now do Open, Write and Read (the later multiple ways) for each
permission and each compressor we have configured to cover more cases
and especially ensure that compressors do not change our premissions.
This test is also to be credited for discovering the skippos-fix.

Commit 7335eebea6dd43581d4650a8818b06383ab89901 introduced a bug
that caused FileFd to create insecure permissions when FileFd::Atomic
is used. This commit fixes the permissions and adds a test.
The bug is most likely caused by the confusing "Perm" parameter
that is passed to Open() - its not the file permissions but intead
the "mode" part of open/creat.

Packages in the "deinstall ok config-file" have no candidate or
instaleld version. So they must be special cased in the apt list
generation.

In commit 446551c8 I changed MarkInstall to discard the candidate if the
candidate can't satisfy the dependency. This breaks interactive solvers
like aptitude which can change the candidate on-the-fly later.
In commit df77d8a5 I introduced this 'early' loop-breaking to begin with
which can't be that helpful for interactive solvers as well, but makes
perfect sense for non-interactives to stop them from exploring trees
which can't be satisfied, but it isn't perfect as ideally we would check
this before auto-installing the first dependency.
This commit therefore moves the loop into its own IsInstallOk hook so
that frontends can override this check if they want to and in exchange
removes the loop-breaking from MarkInstall itself and does it before any
dependency is installed.

We have to properly close our pseudo terminals even in error cases
before we call post-invoke scripts. This is done now by breaking from
the dpkg calling loop instead of copying the handling, which did it in
the wrong order before.
This also ensures that our state file is written in error cases to
record autobit and co as this was forgotten before.

Metapackages like "linux-image-amd64" are otherwise matched by our
extraction as well, which later on can't be successfully compared via
dpkg --compare-versions as the 'amd64' bit isn't a version number.
(Luckily none of our architectures starts with a digit.)
This was broken by me in 0.9.16 as I moved a shell-glob matcher to a
regex-based one which has slightly different semantics regarding '*'.

The framework can be configured to use different compression algorithms
to test different ones, but a testcase testing for gz support should
always be run with gz, regardless of what compressions are configured
otherwise.

As we deal with regex matchers here the dots are treated as wildcards if
we don't take care of escaping them. Not very likely that this could be
a real-world problem, but just to be sure.

kfreebsd as well as hurd kernel packages call the postinst script as
well so we just need to enable the correct parsing for installed
packages and disable the "protect every version" hammer for them.

With APT::VersionedKernelPackages users have the option of adding
packages like pre-build out-of-tree modules to the list of automatically
protected from being autoremoved.
