This finishes the transition to the assume cache as source of truth for the
current set of claims.
The tests have to be adapted. It's not enough anymore to directly put objects
into the informer store because that doesn't change the assume cache
content. Instead, normal Create/Update calls and waiting for the cache update
are needed.
This enables connecting the event handler for ResourceClaim to the assume
cache, which addresses a theoretic race condition.
It may also be useful for implementing the autoscaler support, because now
the autoscaler can modify the content of the cache.
This is a basic implementation of a first-in-first-out queue with unbounded
size. It's useful for cases where a channel with fixed size might deadlock.
The caller is responsible for locking.
Instead of erroring during the preflight check 'CreateJob'
from "upgrade" commands when there are no schedulable nodes,
show a warning.
This can happen in single node clusters.
Also increase the Job TTL after completion to 20 seconds
to make sure it's more than the timeout what waits
for the Job to complete.
In a Prow job, the current work tree is the result of merging a PR into the
target. We want apidiff.sh from there, but then need to invoke it for two
specific revisions and compare.
While at it, output and usability get enhanced. The directory parameter(s) may
be absolute paths or lack the leading . that is required by apidiff.
27a68aee3a introduced context support for events. Creating an event
broadcaster with context makes tests more resilient against leaking goroutines
when that context gets canceled at the end of a test and enables per-test
output via ktesting.
While at it, all context.TODO calls get removed in files that were touched.
There's no reason for having the interface because there is only one
implementation. Makes the implementation of the test functions a bit
simpler (no casting). They are still stand-alone functions instead of methods
because they should not be considered part of the "normal" API.
This is now used by both the volumebinding and dynamicresources plugin, so
promoting it to a common helper package is better.
In terms of functionality, nothing was changed. Documentation got
updated (warns about storing locally modified objects, clarifies what the Get
parameters are). Code coverage should be a bit better than before (tested with
and without indexer, exercises event handlers, more error paths).
Checking for specific errors can now be done via errors.Is.
The script failed in the Prow job with:
fatal: Not a valid object name origin/master
That came from "git merge-base origin/master HEAD", which isn't needed because
the Prow job intentionally sets -r explicitly.
Now the fallback is only tried if needed. While at it, the informational
messages get enhanced.
