58fea5dfaf cmd/go: add telemetry counters for flag names and subcommand
For #58894,#65586

This is a revert of CL 560655 which was a revert of CL 559519.
CL 559519 was reverted because it was broken on windows/386. But now
CL 562715 pulls in x/telemetry CL 560462 which disables telemetry on
windows/386, fixing that issue.

4e91c5697a internal/goroot: in IsStandardPackage check for go source files
Be more strict in IsStandardPackage: before this change we'd just
check for the existence of the directory, but now we check to see that
there's at least one .go file in the directory.

Also update some comments in the modindex package to reflect the fact
that an IndexPackage might represent a directory that does not contain
any source files.

Fixes #65406

d3d390984b internal/trace/v2: store stacks as PCs, not frames
Most stacks share some frames, especially prefixes, and deduplicating
them can save significant amounts of memory.

This will be especially true when we convert traces from the old to the
new format. Here, all stacks exist in a single generation and will be
live together.

For busy traces, such as one of running Staticcheck on std, with CPU
profiling enabled, this change saves ~400 MiB of memory.

c098400548 runtime,internal/syscall/windows: remove long path support check
The runtime currently enables long path support process-wide by updating
the process environment block (PEB). It then tries to create a file
using a long path to check if the PEB update made any difference.

There hasn't been any report that the PEB update was not effective,
and the check itself is quite tricky, so it's time to remove it.

While here, linkname `runtime.canUseLongPaths` to a variable in
internal/syscall/windows instead of the os package so it is easier to
consume from other packages.

Because methods associated with named types are in the
same package as the type, when looking up a method we
don't need to check the package repeatedly.

Rename the global lookupMethod function to methodIndex,
to match the corresponding fieldIndex function (cleanup).

Implement Named.methodIndex, optimized for method lookup
on named types (optimization).

f81e498673 go/types, types2: better errors for non-existing fields or methods
This CL improves the error messages reported when a field or method
name is used that doesn't exist. It brings the error messges on par
(or better) with the respective errors reported before Go 1.18 (i.e.
before switching to the new type checker):

Make case distinctions based on whether a field/method is exported
and how it is spelled. Factor out that logic into a new function
(lookupError) in a new file (errsupport.go), which is generated for
go/types. Use lookupError when reporting selector lookup errors
and missing struct field keys.

Add a comprehensive set of tests (lookup2.go) and spot tests for
the two cases brought up by the issue at hand.

Adjusted existing tests as needed.

Fixes #49736.

39ec246e73 cmd/go: avoid copying a binary to be exec'd in TestScript/gotoolchain_path
Runinng 'go build' writes the binary in a separate process, so avoids
the race described in #22315. However, the script engine's 'cp'
command currently executes in-process, so it does not avoid that bug
and may retain stale file descriptors when running tests in parallel.

Avoid the race in this particular test by giving the final binary
location in the '-o' argument instead of copying it there after the
fact.

Fixes #64019.

6f44cc88f5 archive/zip: reduce memory held by Writer.Copy
Make a copy of the argument File's FileHeader, and pass a pointer
to the copy to CreateRaw.

Passing the pointer directly causes the entire `File` to be referenced
by the receiver. The `File` includes a reference to the `ReaderAt`
underlying the `Reader`, so all its memory, which may be the entire
contents of the archive, is prevented from being garbage-collected.

Also, explain the issue in the doc comment for CreateRaw. We
cannot change its behavior because someone may depend on the
preserving the identity of its argument pointer.

For #65499.

In CL 356611 I changed cmd/go to run most of its tests (instead of

long tests in a cross-compiled configuration, some of the tests have
rotted since then.

This fixes 'GOARCH=386 go test cmd/go' on my workstation.

6d3c1ce885 cmd: update golang.org/x/telemetry to 1cb064e and vendor it
This brings in CL 559505 which adds a stub for counter.CountFlags so
it can be depended on and still build on Go 1.18 and earlier. This
will allow the go command to use counter.CountFlags and still be able
to build as the bootstrap command with an earlier version of Go.

ac08c05d4d cmd/go: fix build config before creating actions for 'go list -cover'
When -covermode is set to atomic, instrumented packages need to import
sync/atomic. If this is not already imported by a package being
instrumented, the build needs to ensure that sync/atomic is compiled
whenever 'go list' is run in a way that triggers package builds.

The build config was already being made to ensure the import, but only
after the action graph had been created, so there was no guarantee that
sync/atomic would be built when needed.

Fixes #65264.
