[release-branch.go1.14] hash/maphash: don't discard data on random seed init
Hash initializes seed on the first usage of seed or state with initSeed.
initSeed uses SetSeed which discards accumulated data.
This causes hash to return different sums for the same data in the first use
and after reset.
This CL fixes this issue by separating the seed set from data discard.

cmd/link, runtime: skip holes in func table
On PPC64 when external linking, for large binaries we split the
text section to multiple sections, so the external linking may
insert trampolines between sections. These trampolines are within
the address range covered by the func table, but not known by Go.
This causes runtime.findfunc to return a wrong function if the
given PC is from such trampolines.
In this CL, we generate a marker between text sections where
there could potentially be a hole in the func table. At run time,
we skip the hole if we see such a marker.

We do it at the entry of asyncPreempt, which is immediately

actually injected a call. It does not cover other exits where we
don't inject a call, e.g. failed preemption, profiling signal, or

async signals, preempting a tight numerical loop, which we

go/build: populate partial package information in importGo
This is a followup to CL 199840 and CL 203820. Cumulatively, they caused
a previously known bug to trigger more often while also nearly fixing it.
This change is a small fixup to CL 199840 that resolves the known bug
and prevents it from causing an additional regression in Go 1.14.
Part 1
The intention in CL 199840 was to return the same error that 'go list'
reported when the package wasn't located, so an early return was added.
However, to determine whether the package was located or not, p.Dir was
unintentionally checked instead of dir.
p is initialized to &Package{ImportPath: path} at top of Context.Import,
and its Dir field is never set before that line in importGo is reached.
So return errors.New(errStr) was always executed whenever errStr != "".
Originally, in CL 125296, the "go list" invocation did not include an
'-e' flag, so it would return a non-zero exit code on packages where
build constraints exclude all Go files, and importGo would return an
error like "go/build: importGo import/path: unexpected output: ...".
CL 199840 added an '-e' flag to the "go list" invocation, but checking
the wrong dir variable caused partial package information to never get
populated, and thus issue #31603 continued to occur, although with a
different error message (which ironically included the location of the
package that was supposedly "not found").
Now that the right dir is checked, issue #31603 is fixed.
Part 2
importGo checks whether it can use the go command to find the directory
of a package. In Go 1.13.x and earlier, one of the conditions to use the
go command was that the source directory must be provided.
CL 203820 made a change such that knowing the source directory was
no longer required:
// To invoke the go command,
-// we must know the source directory,
// ...
That meant build.Import invocations where srcDir is the empty string:
build.Import(path, "", build.FindOnly)
Started using the go command to find the directory of the package, and
started to run into issue #31603 as well. That's the #37153 regression.
Since this change fixes issue #31603, it also fixes issue #37153.
Part 3
There is one more thing. Delete the debugImportGo constant, it's unused.

go/doc: clarify that NewFromFiles caller must filter by GOOS/GOARCH
The most well known and important build constraints to take into
account when rendering package documentation are the GOOS/GOARCH
values. Make it more clear in the NewFromFiles documentation that
they are a part of all build constraints that the caller is
responsible for filtering out.
Also suggest the "go/build".Context.MatchFile method for performing
file matching. The logic to perform build context file matching is
subtle and has many rules that aren't well known (for example,
taking the gc or gccgo compiler into account). It is currently the
only exported API in the standard library that implements this logic,
and it would be unfortunate if people attempt to re-create it because
they don't realize it is already available.

doc/install.html: streamline the “Test your installation” step and make it module-agnostic
In CL 199417, we updated “How to Write Go Code” to give a basic
introduction to modules and to include module-mode commands.
However, most new users will end up reading “Getting Started”
(doc/install.html) before “How to Write Go Code”, and we forgot to
update the handful of commands there for module mode.
Before this change, the “Test your installation” section also covered
quite a few operations beoyond merely testing the installation: it
included setting up a GOPATH, building a binary, and installing and
cleaning binaries. Those are valuable operations to learn, but they
arguably belong in “How to Write Go Code”, not “Test your
installation” — and having all that extra detail in the install
instructions may well discourage folks from further essential reading.
Rather than updating all of those operations here, I've removed them.
A companion CL will update “How to Write Go Code” to ensure that it
mentions GOPATH (as the location of the module cache and the default
install location for binaries) and 'go clean -i'.

runtime: don't treat SIGURG as a bad signal
It's possible for the scheduler to try to preempt a goroutine running
on a thread created by C code just as the goroutine returns from Go code
to C code. If that happens, the goroutine will have a nil g,
which would normally cause us to enter the badsignal code.
The badsignal code will allocate an M, reset the signal handler,
and raise the signal. This is all wasted work for SIGURG,
as the default behavior is for the kernel to ignore the signal.
It also means that there is a period of time when preemption requests
are ignored, because the signal handler is reset to the default.
And, finally, it triggers a bug on 386 OpenBSD 6.2. So stop doing it.
No test because there is no real change in behavior (other than on OpenBSD),
the new code is just more efficient

doc/go1.14: remove TODO about Illumos port
There is an active builder that was added in CL 201597,
and it is passing on Go tip and release-branch.go1.13
(with one failure that appears to be flaky due to being
out of memory). It's also passing on all golang.org/x repos
on tip and release-branch.go1.13. It's not configured to
run on Go 1.12 release branches.

doc/go1.14: move "Minor changes to the library" heading up
This heading was below the minor changes to the standard library.
It should be on top.
Many of the minor changes have been documented, so remove the broad
TODO comment. It is still a TODO to highlight more prominent changes
to the library, if there are any, under the "Core library" heading.

go/types: unexport Checker.LookupFieldOrMethod
Implementation changes in go/types for #6977 required that internal
LookupFieldOrMethod calls had access to the current *Checker. In
order to make quick progress, I added a *Checker receiver to the
function LookupFieldOrMethod (thus making it a method), and added
a new function LookupFieldOrMethod. The plan was always to rename
that function (Checker.LookupFieldOrMethod) such that it wouldn't
be exported; with the obvious name being Checker.lookupFieldOrMethod.
But that name was already in use which is why I postponed the rename.
Eventually I forgot to clean it up. This CL fixes that with the
following renames:
