1f9dce749d cmd/go: download fewer dependencies in 'go mod download'
In modules that specify 'go 1.17' or higher, the go.mod file
explicitly requires modules for all packages transitively imported by
the main module. Users tend to use 'go mod download' to prepare for
testing the main module itself, so we should only download those
relevant modules.

In 'go 1.16' and earlier modules, we continue to download all modules
in the module graph (because we cannot in general tell which ones are
relevant without loading the full package import graph).

'go mod download all' continues to download every module in
'go list all', as it did before.

Fixes #44435

1ce6fd03b8 cmd/gofmt: format files in parallel
gofmt is pretty heavily CPU-bound, since parsing and formatting 1MiB
of Go code takes much longer than reading that amount of bytes from
disk. However, parsing and manipulating a large Go source file is very
difficult to parallelize, so we continue to process each file in its
own goroutine.

A Go module may contain a large number of Go source files, so we need
to bound the amount of work in flight. However, because the
distribution of sizes for Go source files varies widely — from tiny
doc.go files containing a single package comment all the way up to
massive API wrappers generated by automated tools — the amount of
time, work, and memory overhead needed to process each file also
varies. To account for this variability, we limit the in-flight work
by bytes of input rather than by number of files. That allows us to
make progress on many small files while we wait for work on a handful
of large files to complete.

The gofmt tool has a well-defined output format on stdout, which was
previously deterministic. We keep it deterministic by printing the
results of each file in order, using a lazily-synchronized io.Writer
(loosly inspired by Haskell's IO monad). After a file has been
formatted in memory, we keep it in memory (again, limited by the
corresponding number of input bytes) until the output for all previous
files has been flushed. This adds a bit of latency compared to
emitting the output in nondeterministic order, but a little extra
latency seems worth the cost to preserve output stability.

This change is based on Daniel Martí's work in CL 284139, but using a
weighted semaphore and ephemeral goroutines instead of a worker pool
and batches. Benchmark results are similar, and I find the concurrency
in this approach a bit easier to reason about.

In the batching-based approach, the batch size allows us to "look
ahead" to find large files and start processing them early. To keep
the CPUs saturated and prevent stragglers, we would need to tune the
batch size to be about the same as the largest input files. If the
batch size is set too high, a large batch of small files could turn
into a straggler, but if the batch size is set too low, the largest
files in the data set won't be started early enough and we'll end up
with a large-file straggler.

One possible alternative would be to sort by file size instead of
batching: identify all of the files to be processed, sort from largest
to smallest, and then process the largest files first so that the
"tail" of processing covers the smallest files. However, that approach
would still fail to saturate available CPU when disk latency is high,
would require buffering an arbitrary amount of metadata in order to
sort by size, and (perhaps most importantly!) would not allow the
`gofmt` binary to preserve the same (deterministic) output order that
it has today.

In contrast, with a semaphore we can produce the same deterministic
output as ever using only one tuning parameter: the memory footprint,
expressed as a rough lower bound on the amount of RAM available per
thread. While we're below the memory limit, we can run arbitrarily
many disk operations arbitrarily far ahead, and process the results of
those operations whenever they become avaliable. Then it's up to the
kernel (not us) to schedule the disk operations for throughput and
latency, and it's up to the runtime (not us) to schedule the
goroutines so that they complete quickly.

In practice, even a modest assumption of a few megabytes per thread
seems to provide a nice speedup, and it should scale reasonably even
to machines with vastly different ratios of CPU to disk. (In practice,
I expect that most 'gofmt' invocations will work with files on at most
one physical disk, so the CPU:disk ratio should vary more-or-less
directly with the thread count, whereas the CPU:memory ratio is
more-or-less independent of thread count.)

9a58aa267e spec: fix prose about terminating statements
CL 85215 added prose to provide some minimal intuition for the
definition of a "terminating statement". While the original definition
was perfectly fine, the added prose was actually incorrect: If the
terminating statement is a goto, it might jump to a labeled statement
following that goto in the same block (it could be the very next
statement), and thus a terminating statement does not in fact
"prevent execution of all statements that lexically appear after
it in the same block".

Rather than explaining the special case for gotos with targets that
are lexically following the goto in the same block, this CL opts for
a simpler approach.

Thanks to @3bodar (Github) for finding this.

Fixes #48323.

0e598e7da4 syscall: add SyscallN
This CL adds a new syscall.SyscallN API.

The proposal discussion also suggests the API should not only for
Windows but other platforms. However, the existing API set already
contain differences between platforms, hence the CL only implements
the Windows platform.

Moreover, although the API offers variadic parameters, the permitted
parameters remains up to a limit, which is selected as 42, and arguably
large enough.

63b968f4f8 doc/go1.17: clarify Modules changes
Writing CL 333629 clarified my thinking about the behavioral changes
associated with lazy loading. There are really two interrelated
changes — graph pruning, and lazy loading proper — that are both made
possible by the added redundancy in the go.mod file.

(I had initially approached the whole cluster of features as “lazy
loading” because that was the starting point for the design. Graph
pruning came into the picture when we looked at how to bound the
worst-case behavior of lazy loading, but it is really the more
important of the two aspects of the design.)

Note that this change adds links to doc anchors added in CL 333629.

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

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

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%

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

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.

6de8443f3b doc/asm: add a section on go_asm.h, clean up go_tls.h section
Currently the only mention of go_asm.h is buried in a confusing
section about the runtime-specific go_tls.h header. We actually want
people to use go_asm.h, so this CL adds a section with a proper
discussion of this header. As part of this, we remove the discussion
of go_asm.h from the go_tls.h section and clean up what remains.

I stumbled on this when working on the internal ABI specification. I
wanted to refer to stable documentation on how to access struct fields
from assembly and found there was none.
