Bryan C. Mills c814ac44c0 cmd/go: fix TestScript/list_test_e on Windows
I forgot to run trybots on CL 123758, and the test failed on Windows because I
hard-coded a slash-delimited path.

Use the tent-in-a-box operator ([/\\]) to make the path platform-agnostic.

David du Colombier 0ba03b8f42 cmd/go: fix TestScript on Plan 9
CL 123577 added TestScript. The install_rebuild_gopath
test was failing on Plan 9 because it defines a GOPATH
using the ':' separator, while Plan 9 expects the '\000'

This change fixes the script engine by defining a new
":" environment variable set to OS-specific path list
separator.

The install_rebuild_gopath test has been updated to use
"${:}" instead of ":".

Richard Musiol fec97c0aa7 syscall/js: show goroutine stack traces on deadlock
When using callbacks, it is not necessarily a deadlock if there is no
runnable goroutine, since a callback might still be pending. If there
is no callback pending, Node.js simply exits with exit code zero,
which is not desired if the Go program is still considered running.
This is why an explicit check on exit is used to trigger the "deadlock"
error. This CL makes it so this is Go's normal "deadlock" error, which
includes the stack traces of all goroutines.

Russ Cox ca642bb326 cmd/go: warn about non-use of go.mod in legacy go get
It's important for a smooth transition for non-module users
not to change operation in GOPATH/src by default in Go 1.11,
even if go.mod exists in a downloaded dependency.

Even so, users create go.mod and then are confused about
why 'go get' commands seem to behave oddly, when in fact
they are getting the old 'go get'.

Try to split the difference by printing a warning in 'go get'
when run in a tree that would normally be considered a
module if only it were outside GOPATH/src.

Russ Cox 764d0bb031 cmd/go: diagnose 'go mod' in GOPATH/src better
People are (understandably) confused by creating go.mod files in GOPATH/src
and then having the go command not use modules in those directories.
We can't change that behavior (or we'll break non-module users of GOPATH)
but we can force 'go mod' (including 'go mod -init') to fail loudly in that case.

If this is not enough, the next step would be to print a warning every time
the go command is run in a GOPATH/src directory with a go.mod but
module mode hasn't triggered. But that will annoy all the non-module users.
Hopefully anyone confused will eventually run a 'go mod' command of
some kind, which will fail loudly.

Russ Cox 9430c1a669 cmd/go/internal/modfetch: move to new pseudo-version design
The original pseudo-version design used versions of the form

	v0.0.0-yyyymmddhhmmss-abcdef123456

These were intentionally chosen to be valid semantic versions
that sort below any explicitly-chosen semantic version (even v0.0.0),
so that they could be used before anything was tagged but after
that would essentially only be useful in replace statements
(because the max operation during MVS would always prefer
a tagged version).

Then we changed the go command to accept hashes on the
command line, so that you can say

	go get github.com/my/proj@abcdef

and it will download and use v0.0.0-yyyymmddhhmmss-abcdef123456.

If you were using v1.10.1 before and this commit is just little bit
newer than that commit, calling it v0.0.0-xxx is confusing but
also harmful: the go command sees the change from v1.10.1 to
the v0.0.0 pseudoversion as a downgrade, and it downgrades other
modules in the build. In particular if some other module has
a requirement of github.com/my/proj v1.9.0 (or later), the
pseudo-version appears to be before that, so go get would
downgrade that module too. It might even remove it entirely,
if every available version needs a post-v0.0.0 version of my/proj.

This CL introduces new pseudo-version forms that can be used
to slot in after the most recent explicit tag before the commit.
If the most recent tagged commit before abcdef is v1.10.1,
then now we will use

	v1.10.2-0.yyyymmddhhmmss-abcdef123456

This has the right properties for downgrades and the like,
since it is after v1.10.1 but before almost any possible
successor, such as v1.10.2, v1.10.2-1, or v1.10.2-pre.

This CL also uses those pseudo-version forms as appropriate
when mapping a hash to a pseudo-version. This fixes the
downgrade problem.

Overall, this CL reflects our growing recognition of pseudo-versions
as being like "untagged prereleases".

Issue #26150 was about documenting best practices for how
to work around this kind of accidental downgrade problem
with additional steps. Now there are no additional steps:
the problem is avoided by default.

Fixes #26150.

Russ Cox 472e92609a cmd/go/internal/module: add new +incompatible version build annotation
Repos written before the introduction of semantic import versioning
introduced tags like v2.0.0, v3.0.0, and so on, expecting that
(1) the import path would remain unchanged, and perhaps also
(2) there would be at most one copy of the package in a build.

We've always accommodated these by mapping them into the
v0/v1 version range, so that if you ran

    go get k8s.io/client-go@v8.0.0

it would not complain about v8.x.x being a non-v1 version and
instead would map that version to a pseudo-version in go.mod:

    require k8s.io/client-go v0.0.0-20180628043050-7d04d0e2a0a1

The pseudo-version fails to capture two important facts: first,
that this really is the v8.0.0 tag, and second, that it should be
preferred over any earlier v1 tags.

A related problem is that running "go get k8s.io/client-go"
with no version will choose the latest v1 tag (v1.5.1), which
is obsolete.

This CL introduces a new version suffix +incompatible that
indicates that the tag should be considered an (incompatible)
extension of the v1 version sequence instead of part of its
own major version with its own versioned module path.
The requirement above can now be written:

    require k8s.io/client-go v8.0.0+incompatible

(The +metadata suffix is a standard part of semantic versioning,
and that suffix is ignored when comparing two versions for
precedence or equality. As part of canonicalizing versions
recorded in go.mod, the go command has always stripped all
such suffixes. It still strips nearly all: only +incompatible is
preserved now.)

In addition to recognizing the +incompatible, the code that
maps a commit hash to a version will use that form when
appropriate, so that

    go get k8s.io/client-go@7d04d0

will choose k8s.io/client-go@v8.0.0+incompatible.

Also, the code that computes the list of available versions from
a given source code repository also maps old tags to +incompatible
versions, for any tagged commit in which a go.mod file does not exist.
Therefore

    go list -m -versions k8s.io/client-go@latest

will show

    k8s.io/client-go v1.4.0 v1.5.0 v1.5.1 v2.0.0-alpha.0+incompatible ... v8.0.0+incompatible

and similarly

    go get k8s.io/client-go

will now choose v8.0.0+incompatible as the meaning of "latest tagged version".

The extraction of +incompatible versions from source code repos
depends on a codehost.Repo method ReadFileRevs, to do a bulk read
of multiple revisions of a file. That method is only implemented for git in this CL.
Future CLs will need to add support for that method to the other repository
implementations.

Documentation for this change is in CL 124515.

Fixes #26238.

Austin Clements 2d4c1ff739 runtime: don't create heap hints outside TSAN's supported heap
TSAN for Go only supports heap address in the range [0x00c000000000,
0x00e000000000). However, we currently create heap hints of the form
0xXXc000000000 for XX between 0x00 and 0x7f. Even for XX=0x01, this
hint is outside TSAN's supported heap address range.

Fix this by creating a slightly different set of hints in race mode,
all of which fall inside TSAN's heap address range.

This should fix TestArenaCollision flakes. That test forces the
runtime to use later heap hints. Currently, this always results in
TSAN "failed to allocate" failures on Windows (which happens to have a
slightly more constrained TSAN layout than non-Windows). Most of the
time we don't notice these failures, but sometimes it crashes TSAN,
leading to a test failure.

David Chase 2fe2aa0983 cmd/compile: avoid compressed dwarf when testing for gdb on OSX
Until we figure out how to deal with gdb on Darwin (doesn't
read compressed DWARF from binaries), avoid compressing
DWARF in that case so that the test will still yield meaningful
results.

This is also reported to be a problem for Windows.

Problem also exists for lldb, but this test doesn't check
lldb.

Updates #25925

Daniel Martí ba6974fdc3 cmd/compile: fix crash on invalid struct literal
If one tries to use promoted fields in a struct literal, the compiler
errors correctly. However, if the embedded fields are of struct pointer
type, the field.Type.Sym.Name expression below panics.

This is because field.Type.Sym is nil in that case. We can simply use
field.Sym.Name in this piece of code though, as it only concerns
embedded fields, in which case what we are after is the field name.

Added a test mirroring fixedbugs/issue23609.go, but with pointer types.

Fixes #26416.
