This improves performance of the text formatting and ktesting.
Because ktesting no longer buffers messages by default, one unit
test needs to ask for that explicitly.
The updated klog provides a reusable test suite for output handling.
Using it increases our test coverage without having to copy the test cases from
there into some JSON specific test suite.
The new release adds support for multi-line string output (required for
contextual logging) and Verbose.InfoSDepth (required to properly attach
verbosity to some log messages in helper code).
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.
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").
The new releases of klog (via klogr) and logr expose support for call
traces via a new WithCallDepth API in logr.
The new klogr can be configured to pass structured log entries into
klog instead of turning them into a single text message.
