791f758075 archive/zip: tolerate compressed directories with zero uncompressed size
In CL 449955 we made reading of directories with associated file data
an error, since it is a "must not" in the zip specification. It turns
out that a number of implementations make the mistake of not setting
the correct compression method on directories (in particular the Java
jar tool does this when storing the META-INF directory). If the
compression method used is not 0 (stored) then the compressed size of
the directory can be > 0, despite the uncompressed size still being 0.

Since this mistake is not uncommon, we are forced to tolerate it. We
still fail if the recorded uncompressed size is > 0, which should be
a significantly harder mistake to make.

34ab0bcc5e crypto/ecdsa: verify validity of signature parameters in Verify
CL 353849 removed validation of signature parameters being passed to
Verify which led to two distinct problems. If passed a R or S == 0,
encodeSignature would panic since it expects them to be non-zero.
encodeSignature would also normalize (i.e. make non-negative) parameters
by zero padding them, which would result in a signature being passed to
VerifyASN1 which did not match the input signature, resulting in success
in cases where it should've failed. This change re-adds the verification
that 0 < r,s < N before calling ecnodeSignature.

This was caught because tink runs the wycheproof ECDSA vectors against
Verify, where we only run the vectors against VerifyASN1. We should be
doing both.

15e705ea96 go/types, types2: make the new comparable semantics the default
Ordinary interface types now satisfy comparable constraints.

This change makes the new comparable semantics the default behavior,
depending on the Go -lang version.

It also renames the flag types2.Config.AltComparableSemantics to
types2.Config.OldComparableSemantics and inverts its meaning
(or types.Config.oldComparableSemantics respectively).

Adjust some existing tests by setting -oldComparableSemantics
and add some new tests that verify version-dependent behavior.

The compiler flag -oldcomparable may be used to temporarily
switch back to the Go 1.18/1.19 behavior should this change
cause problems, or to identify that a problem is unrelated
to this change. The flag will be removed for Go 1.21.

For #52509.
For #56548.

c8057d8569 cmd/compile: disallow CMOV optimization with ptr arithmetic as an arg
if q != nil {
        p = &q.f
    }

Which gets rewritten to a conditional move:

    tmp := &q.f
    p = Select q!=nil, tmp, p

Unfortunately, we can't compute &q.f before we've checked if q is nil,
because if it is nil, &q.f is an invalid pointer (if f's offset is
nonzero but small).

Normally this is not a problem because the tmp variable above
immediately dies, and is thus not live across any safepoint. However,
if later there is another &q.f computation, those two computations are
CSEd, causing tmp to be used at both use points. That will extend
tmp's lifetime, possibly across a call.

Fixes #56990

0a8055ef3f cmd/api: rewrite as package test
No one ever runs 'go tool api', because the invocation
has gotten unwieldy enough that it's not practical.
And we don't support it as a standalone tool for other
packages - it's not even in the distribution.

Making it an ordinary package test lets us invoke it
more easily from cmd/dist (as go test cmd/api -check)
and avoids the increasingly baroque code in run.go to
build a command line.

Left in cmd/api even though it's no longer a command
because (1) it uses a package from cmd/vendor and
(2) it uses internal/testenv. Otherwise it could be misc/api.

Fixes #56845.

(v1) holds r2 of a syscall. The latter is only used by 2-ret syscalls.
A 1-ret syscall would not touch R3 but keeps it as is, making r2 be a
random value. Always reset it to 0 before SYSCALL to fix the issue.

Fixes #56426

7a9ce74655 crypto/elliptic: remove deprecation markers
These should be deprecated, but per go.dev/wiki/Deprecated,
that should only happen two releases after the replacement is
available (so Go 1.22).

The deprecation of this package was part of the discussion
of proposal #52221. All that remains is waiting for the new
package to be widely available.

f89b39c0af cmd/compile: reenable inlstaticinit
This was disabled in CL 452676 out of an abundance of caution,
but further analysis has shown that the failures were not being
caused by this optimization. Instead the sequence of commits was:

CL 450136 cmd/compile: handle simple inlined calls in staticinit
...
CL 449937 archive/tar, archive/zip: return ErrInsecurePath for unsafe paths
...
CL 451555 cmd/compile: fix static init for inlined calls

The failures in question became compile failures in the first CL
and started building again after the last CL.
But in the interim the code had been broken by the middle CL.
CL 451555 was just the first time that the tests could run and fail.

For #30820.

9f2951b5d1 reflect: remove deprecation notices from SliceHeader, StringHeader
There has been no proposal discussion about adding these notices.
Also, even if we did decide to add them, then since their replacements
are only appearing in Go 1.20, go.dev/wiki/Deprecation says that we
should wait until Go 1.22 to add the deprecation notice.

Filed #56906 for the proposal discussion.

Fixes #56905.

CL 450136 fixed a different copy of this error but missed this one.

this is the text before this CL:

	b.go:9:15: internal compiler error: 'init': Value live at entry. It shouldn't be. func init, node a.i, value nil

And this CL changes it to:

	b.go:9:15: internal compiler error: 'init': value a.i (nil) incorrectly live at entry

matching the same change in the earlier CL.

72fdecafc0 spec: add a link to Allocation section in section on append built-in
If needed, the built-in function append allocates a new underlying
array. While we (probably) don't want to specify exactly how much
is allocated (the prose is deliberately vague), if there's more
space allocated than needed (cap > len after allocation), that
extra space is zeroed. Use an explicit link to the section on
Allocation which explicitly states that newly allocated memory
is zeroed.

Fixes #56684.

753ad5e1d5 spec: document that trailing comma is valid after index in index expressions
At parse time we don't know if a[i] is an index expression or a
type (or function) instantiation. Because instantiations accept
a list of type arguments, and argument lists permit a trailing
comma, a[i,] is either an instantiation or index expression.

Document that a trailing comma is permitted in the syntax for
index expressions.

For comparison, the same problem arises with conversions which
cannot be distinguished from function calls at parse time. The
spec also permits a trailing comma for conversions T(x,). The
grammar adjustment is the same (see line 5239).

Fixes #55007.

1fbfc2f6eb cmd/go: fix the DefaultCC check if CC is an absolute file missing an extension on Windows
This undoes the code (but not test) change from CL 451219, which turns
out to be slightly harmful on Windows (because it doesn't resolve the
file extension for an absolute CC path) and unnecessary elsewhere
(because calling LookPath on a fully-resolved executable path already
stats¹ that path before returning it).

21015cf6ba all: enable disabled HTTP/2 tests
Update net/http to enable tests that pass with the latest update
to the vendored x/net.

Update a few tests:

Windows apparently doesn't guarantee that time.Since(time.Now())
is >=0, so to set a definitely-expired write deadline, use a time
firmly in the past rather than now.

Put a backoff loop on TestServerReadTimeout to avoid failures
when the timeout expires mid-TLS-handshake. (The TLS handshake
timeout is set to min(ReadTimeout, WriteTimeout, ReadHeaderTimeout);
there's no way to set a long TLS handshake timeout and a short
read timeout.)

Don't close the http.Server in TestServerWriteTimeout while the
handler may still be executing, since this can result in us
getting the wrong error.

Change the GOOS=js fake net implementation to properly return
ErrDeadlineExceeded when a read/write deadline is exceeded,
rather than EAGAIN.

Reason for revert: This change causes test failures (and possibly other

Rolling back the change for now to give us more time to consider its

for 1.21 if we do want to make the change.
