86743e7d86 image: add RGBA64Image interface
The new RGBA64At method is equivalent to the existing At method (and the
new SetRGBA64 method is equivalent to the existing Set method in the
image/draw package), but they can avoid allocations from converting
concrete color types to the color.Color interface type.

Also update api/go1.17.txt and doc/go1.17.html

Fixes #44808

df35ade067 doc/go1.17: document //go:build lines
In 1.17, //go:build lines are fully supported. This entails changes to
the go command, vet, and gofmt. Document all of them.

I'm not Russ, but this is a significant change, it slipped under the
radar, and we're trying to get the release out. So here's what I got.

I wasn't sure where to put the go command change. On the one hand,
it's pretty significant. On the other, it certainly affects fewer
people than lazy loading. So it probably shouldn't be first, but I also
didn't want to bury it the middle of all the other module changes. Open
to suggestions.

4fb10b2118 cmd/go: in 'go mod download' without args, don't save module zip sums
'go mod download' without arguments is frequently used to populate the
module cache. It tends to fetch a lot of extra files (for modules in
the build list that aren't needed to build packages in the main
module). It's annoying when sums are written for these extra files.

'go mod download mod@version' will still write sums for specific
modules in the build list. 'go mod download all' still has the
previous behavior.

For now, all invocations of 'go mod download' still update go.mod and
go.sum with changes needed to load the build list (1.15 behavior).

Fixes #45332

We were already setting GIT_SSH_COMMAND (if unset) to explicitly
include 'ControlMaster=no' in order to disable connection pooling.
Now we also set 'BatchMode=yes' to suppress password prompts for
password-protected keys.

While we're here, we also set GCM_INTERACTIVE=never to suppress
similar prompts from the Git Credential Manager for Windows.

bb09f8a29b time: make time.Time print a valid Go string with %#v
Previously calling fmt.Sprintf("%#v", t) on a time.Time value would
yield a result like:

    time.Time{wall:0x0, ext:63724924180, loc:(*time.Location)(nil)}

which does not compile when embedded in a Go program, and does not
tell you what value is represented at a glance.

This change adds a GoString method that returns much more legible
output:

    "time.Date(2009, time.February, 5, 5, 0, 57, 12345600, time.UTC)"

which gives you more information about the time.Time and also can be
usefully embedded in a Go program without additional work.

Update Quote() to hex escape non-ASCII characters (copying logic
from strconv), which makes it safer to embed them in the output of
GoString().

Fixes #39034.

7dedc237c5 cmd/go: smooth out upgrade paths for lazy loading
This change adds two possible upgrade paths for lazy loading:

1. Run 'go mod tidy -go=1.17'.

2. Starting in a module with no existing 'go' directive,
   run any 'go' command that updates the go.mod file.

In the latter case, commands other than 'go mod tidy'
may leave the go.mod file *very* untidy if it had non-trivial
dependencies. (The 'go' invocation will promote all
implicit eager dependencies to explicit lazy ones,
which preserves the original module graph — most of which is
not actually relevant.)

'go mod tidy -go=1.17' can be used to enable lazy loading without
accidentally downgrading existing transitive dependencies.

'go mod tidy -go=1.16' can be used to disable lazy loading and clear
away redundant roots in a single step (if reducing the go version), or
to prune away dependencies of tests-of-external-tests (if increasing
the go version).

'go mod tidy -go=1.15' can be used to add dependencies of
tests-of-external-tests, although there isn't much point to that.

DO NOT MERGE

This change still needs an explicit test and a release note.

9a81702b97 cmd/go: enable lazy loading
This change activates the dormant “lazy loading” codepaths added in CL
265777 and its predecessors. Dependencies of modules that declare 'go
1.17' or higher are loaded lazily, and the dependencies in the go.mod
file maintain additional invariants to support more efficient lazy
loading for downstream dependent modules.

See https://golang.org/design/36460-lazy-module-loading for the
detailed design.

764f53eb6c spec: clarify conditions for switch expression type
1. The existing prose implied that a switch expression type must
   be comparable because it is tested for equality against all case
   expressions. But for an empty switch (no case expressions), it
   was not clear if the switch expression needed to be comparable.
   Require it to match the behavior of compiler and type checkers.

2. While making this change, remove redundant language explaining
   what happens with untyped boolean switch expression values: the
   default type of an untyped boolean value is bool, this is already
   covered by the first part of the relevant sentence.

Fixes #43200.

972e883925 runtime/cgo: add Handle for managing (c)go pointers
A non-trivial Cgo program may need to use callbacks and interact with
go objects per goroutine. Because of the rules for passing pointers
between Go and C, such a program needs to store handles to associated
Go values. This often causes much extra effort to figure out a way to
correctly deal with: 1) map collision; 2) identifying leaks and 3)
concurrency.

This CL implements a Handle representation in runtime/cgo package, and
related methods such as Value, Delete, etc. which allows Go users can
use a standard way to handle the above difficulties.

In addition, the CL allows a Go value to have multiple handles, and the
NewHandle always returns a different handle compare to the previously
returned handles. In comparison, CL 294670 implements a different
behavior of NewHandle that returns a unique handle when the Go value is
referring to the same object.

Benchmark:
name                      time/op
Handle/non-concurrent-16  487ns ± 1%
Handle/concurrent-16      674ns ± 1%

Then, write the 'go.mod' file with that version before further
processing. That way, if the command errors out due to a change in
behavior, the reason for the change in behavior will be visible in the
file diffs.

If the 'go.mod' file cannot be written (due to -mod=readonly or
-mod=vendor), assume Go 1.11 instead of the current Go release.
(cmd/go has added 'go' directives automatically, including in 'go mod
init', since Go 1.12.)

13a0f7b502 spec: clarify that signed integers>=0 are permitted as shift counts
In Go1.13 and above, signed integers are permitted as shift counts as long as they are >=0.
However, the comments in the "Arithmetic operators" section says shift operators accept "unsigned integer" as of right operands. Replacing this with "integer>=0" resolves the misunderstanding that shift
operators permit only unsigned integers.

860704317e crypto/tls: add HandshakeContext method to Conn
Adds the (*tls.Conn).HandshakeContext method. This allows
us to pass the context provided down the call stack to
eventually reach the tls.ClientHelloInfo and
tls.CertificateRequestInfo structs.
These contexts are exposed to the user as read-only via Context()
methods.

This allows users of (*tls.Config).GetCertificate and
(*tls.Config).GetClientCertificate to use the context for
request scoped parameters and cancellation.

Replace uses of (*tls.Conn).Handshake with (*tls.Conn).HandshakeContext
where appropriate, to propagate existing contexts.
