Change AutoPackageTest.results() to evaluate the Swift results instead of the
adt-britney ones.
TODO:
- Add more tests (like for adt-britney)
- Drop triggering of adt-britney tests
- Drop adt-britney tests (which fail now)
Add bool whether there is any successful test of src/arch of any version. This
will be used for detecting "regression" vs. "always failed".
WARNING: This changes the results.cache format, so results.cache has to be
removed and recreated before deploying this.
Commit 446 only considered a package's own tests. But we also need to check for
newer results of failed reverse dependency tests. Introduce a new
failed_tests_for_trigger() helper which computes the failed (src, arch) failed
tests for a given package, and fetch new results for all of them.
When collecting results, not only check pending tests, but also new results for
failed tests. This picks up new test results from manual retries which might
now have succeeded.
These usually stem from repeatedly tmpfailing runs where we did not even get as
far as unpacking the source (e. g. repeatedly hitting the ceiling of max
allowed instances/CPUs/etc.). In that case, consider this run a tmpfail result,
instead of ignoring it, as otherwise we end up with that entry being orphaned
in pending.txt.
Until now, autopkgtest results were triggered via an external "adt-britney"
command from lp:auto-package-testing. This required a lot of state files and
duplicated effort, uses hardcoded absolute paths to these external tools, and
is quite hard to understand and maintain. We also want to move away from
Jenkins and rsyncing state files.
Directly retrieve autopkgtest results from a publicly readable and browsable
Swift container, with a debci-compatible layout
(https://wiki.debian.org/debci/DistributedSpec). This now tracks both requests
and results on a per-architecture granularity, so that we can track
per-architecture regressions/always-failed.
Introduce a new ADT_SWIFT_URL config option that sets the swift base URL. If
this key is not set, the behaviour does not change compared to previous
versions, and no results will be retrieved from the cloud.
This still keeps the old adt-britney requests/results as the authoritative
data and for now merely shows the swift results in addition. With that we can
compare the results and run the cloud testing in parallel to find/fix problems
until we switch over. Due to that, the code to britney.py is temporary, does
*not* use AutoPackageTest.results(), and instead just reads the internal
results map.
This is necessary so that we can properly match requested to received results
when the latter arrive in different runs for different architectures.
This also opens up the possibility of per-arch blacklisting later.
Don't use kombu's SimpleQueue() as that always declares queues and we neither
want that (we want to know when we try to talk to a nonexisting queue), nor
might the RabbitMQ ACL allow us to do that. So use kombu.Producer without queue
declaration.
Until now, autopkgtests were triggered via an external "adt-britney" command
from lp:auto-package-testing. This duplicated a lot of effort (such as its own
chdist and reverse dependency calculation), maintains a lot of state files,
uses hardcoded absolute paths to these external tools, and is quite hard to
understand and maintain. We want to get rid of all this.
Add logic to AutoPackageTest.request() to use britney's existing reverse
dependency maps and figure out the set of tests to run for packages in
unstable. These are being tracked in "requested_tests".
Add logic to AutoPackageTest.submit() to send test requests to the AMQP server
specified in the new "ADT_AMQP" config key. For testing this can be a file://
URL, and if not set no test requests will be sent at all.
The set of tests which were requested in previous runs are tracked in
UNSTABLE/autopkgtest/pending.txt, so that we don't re-request tests in
subsequent runs.
There is no implementation for collect() and results() yet, these will be done
in a separate commit.
Add initial test cases.
- A test for a package/version can be triggered by several distincts causes with different results. Modify the data structure to store this instead of only storing the last cause and result, leading to missing test results in excuses.
- Check if failures are regressions (there is at least one pass and migration is blocked) or if test has always been failing. In the latter case, migration is not blocked.
- Add colours to excuses.html to distinguishes the test results
- Point jenkins URL to lastBuild
