The new releases fix logging of KObj in JSON output: klog implements the new
logr.Marshaler interface and zapr uses it instead of Stringer when logging the
ObjectRef created by KObj.
Moving the registry into its own package will avoid dependency cycles in future
PRs.
Creating loggers through a factory instead of storing pre-created instances
will make it possible to create the loggers differently depending on
configuration parameters.
The factory can also be used to provide additional meta data before creating
instances.
The name concatenation and ownership check were originally considered small
enough to not warrant dedicated functions, but the intent of the code is more
readable with them.
It wasn't documented that InitLogs already uses the log flush frequency, so
some commands have called it before parsing (for example, kubectl in the
original code for logs.go). The flag never had an effect in such commands.
Fixing this turned into a major refactoring of how commands set up flags and
run their Cobra command:
- component-base/logs: implicitely registering flags during package init is an
anti-pattern that makes it impossible to use the package in commands which
want full control over their command line. Logging flags must be added
explicitly now, something that the new cli.Run does automatically.
- component-base/logs: AddFlags would have crashed in kubectl-convert if it
had been called because it relied on the global pflag.CommandLine. This
has been fixed and kubectl-convert now has the same --log-flush-frequency
flag as other commands.
- component-base/logs/testinit: an exception are tests where flag.CommandLine has
to be used. This new package can be imported to add flags to that
once per test program.
- Normalization of the klog command line flags was inconsistent. Some commands
unintentionally didn't normalize to the recommended format with hyphens. This
gets fixed for sample programs, but not for production programs because
it would be a breaking change.
This refactoring has the following user-visible effects:
- The validation error for `go run ./cmd/kube-apiserver --logging-format=json
--add-dir-header` now references `add-dir-header` instead of `add_dir_header`.
- `staging/src/k8s.io/cloud-provider/sample` uses flags with hyphen instead of
underscore.
- `--log-flush-frequency` is not listed anymore in the --logging-format flag's
`non-default formats don't honor these flags` usage text because it will also
work for non-default formats once it is needed.
- `cmd/kubelet`: the description of `--logging-format` uses hyphens instead of
underscores for the flags, which now matches what the command is using.
- `staging/src/k8s.io/component-base/logs/example/cmd`: added logging flags.
- `apiextensions-apiserver` no longer prints a useless stack trace for `main`
when command line parsing raises an error.
This tag of hcsshim brings in a couple welcome features/improvements. One being
exposing a way to query for hns endpoint statistics (Packets received/sent etc.).
This tag also contains some optimizations for querying whether a certain HCN feature
is supported, which is a common workflow in kube-proxy on Windows. The first result
from querying HCN is now cached so further calls can skip the hcn query as well as the
version range parsing that was performed. This also gets rid of some redundant logs
that used to hit everytime the version range parsing occurred.
The Go-winio dep bump, and all of the ctrd deps are transitive only. Nothing new is needed/intended
to be used.

This replaces the experimental logr v0.4 with the stable v1.1.0
release. This is a breaking API change for some users because:
- Comparing logr.Logger against nil is not possible anymore:
it's now a struct instead of an interface. Code which
allows a nil logger should switch to *logr.Logger as type.
- Logger implementations must be updated in lockstep.
Instead of updating the forked zapr code in json.go, directly using
the original go-logr/zapr is simpler and avoids duplication of effort.
The updated zapr supports logging of numeric verbosity. Error messages
don't have a verbosity (= always get logged), so "v" is not getting
added to them anymore.
Source code logging for panic messages got fixed so that it references
the code with the invalid log call, not the json.go implementation.
Finally, zapr includes additional information in its panic
messages ("zap field", "ignored key", "invalid key").
For the complete release notes, see
- https://github.com/opencontainers/runc/releases/tag/v1.0.2
In particular, this fixes the check cgroup v1 systemd manager check
if a container needs to be frozen before Set(), and adds a knob to
skip the check/freeze entirely (to be used by the next commit).

Add comment outlining TestContextCancel.
Stop calling `t.Errorf` from wrong goroutine.
Package up queueNoteFn expectation checking.
Add counting of goroutine in req1 exec fn.
Remove unnecessary assignment to `_`.
Make TestContextCancel wait on fake clock, to insulate timing check
from scheduler noise.
Factor goroutine counting out of queueset.go, into queueset_test.go,
where it matters.
Refactor promise: Use a simple channel-based implementation for normal
code, a mutex-based one for testing code.
Took all the panics out of queueset.go
Shrink the timeouts in promise tests to 1 second.
