If you run
go test -coverpkg=all fmt
one possible interpretation is that you want coverage for all the
packages involved in the fmt test, not all the packages in the world.
Because coverpkg was previously defined as a list of packages
to be loaded, however, it meant all packages in the world.
Now that the go command has a concept of package notation
being used as a matching filter instead of a direct enumeration,
apply that to -coverpkg, so that -coverpkg=all now has the
more useful filter interpretation.

This CL finally adds one of our longest-requested cmd/go features:
a way for test-running harnesses to access test output in structured form.
In fact the structured json output is more informative than the text
output, because the output from multiple parallel tests can be
interleaved as it becomes available, instead of needing to wait for
the previous test to finish before showing any output from the
next test.
See CL 76872 for the conversion details.

The old code only worked for double-quoted strings, and only checked
that the end of the literal value was \n". This worked most of the time,
except for some strings like "foo\\n", which doesn't actually translate

To fix this, unquote the string first and look for a real newline at the
end of it. Ignore errors, as we don't have anything to do with string
literals using back quotes.

an mtime-based build system invoking the go command may not

We want test caching to work even for people with scripts
that set a non-default test timeout. But then that raises the
question of what to do about runs with different timeouts:
is a cached success with one timeout available for use when
asked to run the test with a different timeout?
This CL answers that question by saying that the timeout applies
to the overall execution of either running the test or displaying
the cached result, and displaying a cached result takes no time.
So it's always OK to record a cached result, regardless of timeout,
and it's always OK to display a cached result, again regardless of timeout.

It has always been problematic that there was no way to specify
tool flags that applied only to the build of certain packages;
it was only to specify flags for all packages being built.
The usual workaround was to install all dependencies of something,
then build just that one thing with different flags. Since the
dependencies appeared to be up-to-date, they were not rebuilt
with the different flags. The new content-based staleness
(up-to-date) checks see through this trick, because they detect
changes in flags. This forces us to address the underlying problem
of providing a way to specify per-package flags.
The solution is to allow -gcflags=pattern=flags, which means
that flags apply to packages matching pattern, in addition to the
usual -gcflags=flags, which is now redefined to apply only to
the packages named on the command line.
See #22527 for discussion and rationale.
