If the cruft removal item has a different version than the binary currently in
testing, then the cruft item was replaced since it was added, or it was added
in error. In this case, the item should not be processed.

When the item is a cruft removal item, the variable contains the binary name,
not the source name. So rename it to item_package and set source_name, to the
source in both cases.

The update of gcc to gcc-9 introduced a regression in buildability of
anything relying on kernel headers. This could have been caught by the
kernel's standard rebuild autopkgtest, but we currently only trigger the
linux autopkgtest for source packages named gcc-N, which excludes
gcc-defaults.
Include gcc-defaults in the list of packages that trigger a linux rebuild
test.

When we convert legacy results in the autopkgtest-results.cache file,
we are only touching leaf results. By moving the loops into a
function, we can remove 2-3 levels of ("redundant") nesting. This in
turn makes it more clear what is relevant in the conversion.
This same also holds in save_state when we convert an Enum to a

When an item is migrated to the target suite, always create a new
SourcePackage object with a separate binaries list (independent from the list
in the source suite). That list is updated for every binary that is added,
updated or removed. This should ensure consistent source package information
in the target suite.
The undo code doesn't need to be updated for this, because the old
SourcePackage object is put back on undo, with the old binary list.

The other fields related to invalidation are currently not deterministic and
depend on the order in which the excuses are invalidated.
The new invalidated-by-other-package field is just a boolean which shows the
excuse was invalidated by some other package for some reason (without

In Debian, the same override is applied to both suites and they are
always consistent. It's not the case in Kali, we keep the value from
Debian when we import the package in britney's source distribution, but
if the same version is already present in the target distribution, it
keeps its original section (dating back to its initial import). In those
situations, the code will fail with an error like this one:
E: [2018-12-28T19:57:57+0000] - Mismatch found coinor-libdylp0 1.6.0-1.1 amd64 differs
I: [2018-12-28T19:57:57+0000] - ... section libs != science
[...]
ValueError: Inconsistent / Unsupported data set
Commit 7efa865a04 which was supposed to
move code around introduced the check on this field. Prior to this, the
section was not checked. Since the section only has an impact on which
packages take part to the smooth updates feature, the impact of such a
mismatch is negligible so I simply dropped that check.
This is useful to run tests with the data files from a specific point in time,
without changes due to ageing when the test runs later.

Have the transaction code verify that there is at most one active
child at the time and no one is using the parent while child is
active. This is how the code is intended to be used and also the
code almost certainly does not work otherwise.
The new code does not cover commiting/rolling back a parent before a
child but that is already covered by the existing code (it will
trigger when child transaction is rolled back/committed or when
leaving the contextmanager from start_transaction).
This would have caught 7d758760d1

Correct the return value of current_transaction that treated the
_transaction field incorrectly as a queue rather than a stack like
everything else. This completely broke the ability to commit and

When we try to compute_groups for a group which has a source or a binary with
a lower version than testing, throw an exception. In the cases where this can
happen, the exception is caught. In other cases, it is not and it serves as an
assert.
This can only happen when there are multiple candidates (from multiple suites)
changing the same source or binary.
This should fix the ordering issues tested in these tests:
- tpu-unstable-binnmu
- binnmu-tpu
- tpu-with-unstable-binnmu
With this change, it should be possible to accept binNMUs from *pu again.

Currently autopkgtest tries to install our trigger from unstable and the rest
from testing. If that fails, than autopkgtest has a fall-back to allow all
packages from unstable to be installed. This has two severe issues:
1) the version of the test and the package it came from may be out-of-sync
2) too much from unstable may be installed, even stuff that should not/is not
allowed to migrate as it breaks stuff.
Make sure that test depends also get added to triggers if they are broken.
E.g. imagine the following scenario: trigger X changes (breaks) the output
generated by Y. Package Z has Y in the test dependencies and compares the
output in the autopkgtest. We want to have the opportunity that a new version
is automatically fixing the situation.
Two use cases are currently unsupported: needs-build (autopkgtest restriction)
and test dependencies generated by autodep8.
Admittedly, no policy adds them yet so this is currently no-op code.
However, future commits can start to rely on this infrastructure code.

Flatten the defaultdict(set) for unsat_deps into a standard dict for output
In case autopkgtest triggering is delayed because the required builds aren't
ready yet or the package is not installable, currently there is only the
message that autopktest delays the migration, but no hint why. This commit adds
these hints.
The initial idea was to do this to bootstrap the baseline, but it turns out
that this has the drawback it triggers runs for a package that has a new
autopkgtest where it didn't have it in the version in the target suite. It was
considered harmless (as it would just have a failing reference), but due to
autodep8, package can have a passing result in the target suite while the new
autopkgtest is actually broken. Such a package should not be blocked / getting
a penalty.
The alternative is to make the check here smarter, but as this is only for
bootstrapping, lets do that outside of britney proper.
When determining whether a policy applies to a given item, use the
suite class rather than the suite name.

1) the update didn't happen for all but the first
2) we don't want a package that fixes a regression in unstable to influence the
reference for another package until it actually migrates, so this updating
is flawed.
Given that only one value is defined ("reference"), it is a better
option to allow the config to be unset when one does not want to have
adt_baseline set to "reference".

The first case is to avoid a creating a list, which is then converted
to a set only to throw away the list again. Here we can just create
the set right away without a list inbetween.
The second case is "if x in [...]:" is better written as "if x in
{...}:" as sets provides faster "__contains__" (assuming you are on a
"recent enough python3", which britney is).

- revert most of commit adbe6d5 as checking the version in testing doesn't work
when other packages migrate and cause regressions
- Alternative way of determining if a package is regressing, by comparison to a
reference set. The reference set is to be created by a holy trigger that
doesn't take packages from the base suite, but instead tests in the testing
suite. This reference needs a retry when a package causing regression
migrates nevertheless, e.g. due to hints or to bounty/penalty policy.
This commit rewrites the make-shift "log" methods to use the logging
framework without requiring changes to the callers. This will be done
in a latter commit to keep things reviewable.
