2b4425759c doc: add release notes for changes to encoding/json package
The escaping of certain control characters has been changed.
The change is compliant with the JSON specification.
The JSON package never promised exactly how JSON formatted
and has historically changed its representation over time.

c915215af6 runtime: add the disablethp GODEBUG setting
Go 1.21.1 and Go 1.22 have ceased working around an issue with Linux
kernel defaults for transparent huge pages that can result in excessive
memory overheads. (https://bugzilla.kernel.org/show_bug.cgi?id=93111)

Many Linux distributions disable huge pages altogether these days, so
this problem isn't quite as far-reaching as it used to be. Also, the
problem only affects Go programs with very particular memory usage
patterns.

That being said, because the runtime used to actively deal with this
problem (but with some unpredictable behavior), it's preventing users
that don't have a lot of control over their execution environment from
upgrading to Go beyond Go 1.20.

This change adds a GODEBUG to smooth over the transition. The GODEBUG
setting disables transparent huge pages for all heap memory on Linux,
which is much more predictable than restoring the old behavior.

Fixes #64332.

a27a525d1b go/types: set correct Var.scopePos for parameters/results
Previously, its value was unset (NoPos), but the correct
value is a point after the signature (FuncType.End) and
before the body.

Also, fix a bug in Scope.Innermost whereby it would return
the wrong (outer) scope when the query position was in
the FuncType portion of a Func{Decl,Lit}.
The fix is to set the scope's pos/end to those of the
complete Func{Decl,Lit}. This is now documented at
Info.Scopes, along with other missing information.

Also, fix a bug in the go/types (but not types2) scope
test, in which comments were discarded by the parser,
causing the entire test to be a no-op (!).

Also, make failures of TestScopeLookupParent more
informative.

Also, add a release note about the change in behavior.

30de0b5ef4 go/types, types2: implement Alias proposal (export API)
This CL exports the previously unexported Alias type and
corresponding functions and methods per issue #63223.

Whether Alias types are used or not is controlled by
the gotypesalias setting with the GODEBUG environment
variable. Setting gotypesalias to "1" enables the Alias
types:

	GODEBUG=gotypesalias=1

By default, gotypesalias is not set.

Adjust test cases that enable/disable the use of Alias
types to use -gotypesalias=1 or -gotypesalias=0 rather
than -alias and -alias=false for consistency and to
avoid confusion.

For #63223.

607e020150 cmd/cgo: disable #cgo noescape/nocallback until Go 1.23
Go 1.21 and earlier do not understand this line, causing
"go mod vendor" of //go:build go1.22-tagged code that
uses this feature to fail.

The solution is to include the go/build change to skip over
the line in Go 1.22 (making "go mod vendor" from Go 1.22 onward
work with this change) and then wait to deploy the cgo change
until Go 1.23, at which point Go 1.21 and earlier will be unsupported.

For #56378.
Fixes #63293.

856cf23a8a spec: specify evaluation order for binary logical operations
This CL clarifies the order of evaluation of the binary logical
operators, && and ||. The clarified semantics matches what cmd/compile
and x/tools/go/ssa already implement, and prohibit some optimizations
that are arguably allowed today but risk surprising users.

First, it specifies that the left operand is evaluated before the
right operand. This prohibits "(f() || true) && *p" from evaluating
"*p" before "f()".

Second, it specifies that binary logical operations are also ordered
lexically left-to-right with regard to function calls and receive
operations. This prohibits "h(*p || true || f(), g())" from evaluating
"*p" after "g()".

Finally, the "order of evaluation of [...] is not specified" wording
in the example is clarified to acknowledge that there are still some
other orderings that are implied lexically; e.g., x must be evaluated
and indexed before g(), and z now must be evaluated before h(). (Note:
Whether z is evaluated before or after f() remains unspecified, as
there's no lexical dependency.)

c700c23cef reflect: make Value.IsZero identical to v == zero
The upcoming built-in zero value provides an idiomatic way
to test for zero by comparing to the zero literal: v == zero.

The reflect package is meant to provide a programmatic way to perform
operations that the Go language itself provides.
Thus, it seems prudent that reflect.ValueOf(&v).Elem().IsZero() is
identical to v == zero.

This change alters the behavior of Value.IsZero in two concrete ways:
* negative zero is identical to zero
* blank fields in a struct are ignored

Prior to this change, we were already in an inconsistent state
due to a regression introduced by CL 411478.
The new behavior was already the case for comparable composite types.
This change makes it consistent for all other types
(in particular incomparable composite types and standalone numbers).

6a063b01b0 net: mptcp: force using MPTCP with GODEBUG
When adding MPTCP support to address the proposal #56539, I missed the
GODEBUG setting from Russ Cox's plan:

  I am inclined to say that we add MPTCP as an opt-in for a release or
  two, and then make it opt-out. There should be a GODEBUG setting (...)

See: https://github.com/golang/go/issues/56539#issuecomment-1309294637

Thanks to andrius4669 for having reported this issue to me.

It makes sense to have this GODEBUG setting not to have to modify
applications to use MPTCP (if available). It can then be useful to
estimate the impact in case we want to switch from opt-in to opt-out
later.

The MPTCP E2E test has been modified to make sure we can enable MPTCP
either via the source code like it was already the case before or with
this environment variable:

  GODEBUG=multipathtcp=1

The documentation has been adapted accordingly.

I don't know if it is too late for Go 1.21 but I had to put a version in
the documentation. The modification is small, the risk seems low and
this was supposed to be there from the beginning according to Russ Cox's
specifications. It can also be backported or only be present in the
future v1.22 if it is easier.

Note: I didn't re-open #56539 or open a new one. It is not clear to me
what I should do in this case.

Fixes #56539
