@canonical.com is now DKIM signed and SPF published which means emails
from proposed-migration running on snakefruit sending direct would
likely be caught out. Since we're here, the project is Ubuntu related
so switch to using an @ubuntu.com address instead.
When querying swift there is no way to take results only newer than a
specified point, you can only query newer than or equal to. But for sqlite
we can absolutely use > instead of >= and avoid re-processing results we've
already seen.
Logging all force-reset-test hints for every package causes
about 850 MB of logs in the last run of 880 MB of logs in total,
let's only log ones matching the package instead, as we do for
force-badtest.
In Ubuntu, we only fetch results on demand, so we might not
have seen the results yet.
Debian always fetches results at the beginning so has all the
data ready.
Due to the number of hints in standing use in Ubuntu, hints.search() is an
expensive operation, and we call it once for *every single test* referenced
from -proposed. Since force-reset-test are a small proportion of the hints
in use, searching once for all the hints of this type and only searching
this subset for each autopkgtest improves performance (with 23000
autopkgtests referenced in -proposed, this saves roughly 1 minute of
runtime, or 11% on a 9-minute britney run; the number of packages in
-proposed is typically much higher at other points in the release cycle,
therefore the absolute improvement in performance is expected to be
greater.)
The force-reset-test hints are an Ubuntu delta so this is not expected to be
upstreamed; and it could eventually be dropped if and when baseline
retesting is implemented in Ubuntu and the number of hints required drops.
This could be implemented with a more generic, elegant solution in
HintsCollection, but again, the scalability problem of hints is hopefully
short-lived so I didn't consider it worth the investment here.
urlopen() supports non-http URLs, but when called on them, http-related
features are absent - such as getcode(). Make the code work with file:///
URLs.
Since we've never used remove hints in Ubuntu and never will, we shouldn't
pay the cost for them in britney runs. Remove references to them entirely,
to speed up britney runs.
This is an Ubuntu delta not expected to be upstreamed, and can be dropped at
some future point when we don't have 11,000 active hints. (This count of
hints is expected to drop dramatically once we have autopkgtest baseline
retesting.)
We currently skip the ALWAYSFAIL/REGRESSION handling for kernels. This
can lead to us missing genuine regressions in kernel uploads. The
idea is that results from one kernel flavour shouldn't influence
another.
We can keep this idea but do better and actually check for regressions:
when looking at results, if we're considering a kernel, only look at
results which were triggered by this kernel.
We often introduce new kernels post-release, and we still want to not
trigger tests for the kernel image packages. Check for -meta in the
*source* suite as well as the target.
Fix the -meta name calculation for linux-signed-foo.
We currently skip running autopkgtests where there is an installability
problem, but in a few cases the depends policy notes these only, but
otherwise doesn't block migration on them.
In these cases, let's try to run the autopkgtests anyway. There will be
a few instances of uninstallability here, but since we migrate the
packages we should give them a chance to be tested.
We currently concatenate all triggers together into a string, but the
AMQP consumer expects this to be a list.
When using AMQP, keep the triggers as a list. Ensure that the "real"
trigger (the package being tested) is kept first, as before.
On some distros (Ubuntu), arch:all packages are built along with one of
the architectures. We shouldn't be listing 'all' as its own arch in this
case. Instead we filter out the binaries except for on the
'all_buildarch'.
We just had the autopkgtest queues DoSed because britney was crashing
after requesting each reverse dependency for a perl upload, but before
it had written pending.json out so it knew what not to request again.
This was 25,000 requests per arch...
Let's write pending.json straight after sending each request, so that
the next run - even after a crash - won't re-request the same things
again.
These have a hash appended.
We don't actually use the baseline retrying, which is where the ID
parsing is used, but we might as well handle this, not least so we don't
crash.
The apt version comparison sorts 'blacklisted' greater than most version
numbers, which means that we accidentally apply force hints for version
'blacklisted' to all uploads. Since this is the only case of a hacked
version number, let's special case it so that 'blacklisted' hints only
match packages with 'blacklisted' version.
We're supposed to synthesise an "unknown" version for these, but a bug
in the worker meant we didn't do that in some cases and these leaked
into swift. Let's repair it client-side.
Most DKMS packages do not declare Testsuite: autopkgtest-pkg-dkms, but
we can detect this anyway, and this way we can enforce that the module
is buildable.
It works like this. We wait until all tests have finished running. and
then grab their results. If there are any regressions, we mail each bug
with a link to pending-sru.html. There's a state file which records the
mails we've sent out, so that we don't mail the same bug multiple times.
We want to treat linux-$flavor and linux-meta-$flavor as one set in
britney which goes in together or not at all. We never want to promote
linux-$flavor without the accompanying linux-meta-$flavor.
Add a new LinuxPolicy which runs after most of the other policies, which
invalidates linux-foo if linux-meta-foo is invalid.
