      syscall/js: move callback helper code to misc/wasm to avoid using eval() · 859a944e
      Xudong Zheng authored 
      When using the compiled .wasm with misc/wasm/wasm_exec.js, we get an error message if the site prohibits eval() via the Content-Security-Policy header. This can be resolved by moving the callback helper code from src/syscall/js/callback.go to misc/wasm/wasm_exec.js.

      runtime: fix syscall error returns on mips/mips64/ppc64 · acd30e9a
      David Wimmer authored 
      The linux syscall functions used in runtime are designed around the calling
convention of returning errors as negative numbers. On some other systems
(like mips and ppc) the actual syscalls signal errors in other ways. This
means that the assembly implementations of the syscall functions on these
platforms need to transform the return values in the error cases to match
the expected negative errno values. This was addressed for certain syscalls
in https://golang.org/cl/19455 and https://golang.org/cl/89235. This patch
handles the rest of the syscall functions in sys_linux_*.s that return any
value for mips/mips64/ppc64.

      cmd/cgo: stop expanding typedefs once we reach __builtin types · b8669ef1
      Keith Randall authored 
      Expanding __builtin types (__builtin_va_list, particularly) leads
to problems because they are expanded by the compiler itself - the
expansions are not generated by anything in a .h file. The types
a __builtin type expand to are thus very confusing to cgo.

See CL 126275.

      cmd/doc: adapt directory search for modules · b7d3f4c0
      Russ Cox authored 
      Previously, cmd/doc treated GOROOT/src and GOPATH/src
as the roots of the directory trees holding packages, assuming
that the import path would be the path elements after the src directory.

With modules, each module serves as its own root of a file tree,
and the import path prefix starts with the module path before
adding the path elements after the module root.

There are ways we could make this more efficient,
but for now this is a fairly small adjustment to get 'go doc'
working OK for modules for Go 1.11.

Fixes #26635.

It's also next to dep's cache, $GOPATH/pkg/dep.

      Russ Cox authored 
      The old -getmode flag had two settings:
-getmode=local meant don't download from the network.
-getmode=vendor meant only use the vendor directory.

The new -mod flag has two settings:
-mod=readonly means refuse to automatically update go.mod (mainly for CI testing).
-mod=vendor means only use the vendor directory.

The old GOPROXY variable had two settings:
a proxy URL or else the empty string (direct connect).

The new GOPROXY variable has three settings:
a proxy URL, the string "off" (no network use allowed),
or else the empty string or the explicit string "direct" (direct connection).
We anticipate allow a comma-separated sequence in a future release,
so commas are disallowed entirely right now.

      cmd/go: add $GOFLAGS environment variable · c1a4fc3b
      Russ Cox authored 
      People sometimes want to turn on a particular go command flag by default.
In Go 1.11 we have at least two different cases where users may need this.

1. Linking can be noticeably slower on underpowered systems
due to DWARF, and users may want to set -ldflags=-w by default.

2. For modules, some users or CI systems will want vendoring always,
so they want -getmode=vendor (soon to be -mod=vendor) by default.

This CL generalizes the problem to “set default flags for the go command.”

$GOFLAGS can be a space-separated list of flag settings, but each
space-separated entry in the list must be a standalone flag.
That is, you must do 'GOFLAGS=-ldflags=-w' not 'GOFLAGS=-ldflags -w'.
The latter would mean to pass -w to go commands that understand it
(if any do; if not, it's an error to mention it).

For #26074.
For #26318.
Fixes #26585.

      cmd/go: change list -compiled to populate new CompiledGoFiles list · 53859e57
      Russ Cox authored 
      CL 108156 added -cgo during the Go 1.11 cycle.
To avoid adding a new field to Package, it redefined the
meaning of the CgoFiles list to be the cgo output instead
of the cgo input.

This was awkward in the go command itself, since the meaning
of the list changed midway through the build.

But, worse, it is awkward to users of go list.
When gathering information about a tree of packages,
we may want the names of both the cgo inputs and the cgo outputs
(golang.org/x/tools/go/packages does, it turns out),
or when combined with -deps (CL 107776),
we may only care about one list or the other depending
on whether the package was requested explicitly or is
being returned as a dependency.

Also, it's not general enough. SWIGFiles turn into cgo files
and then end up in the list too. And maybe there will be others
in the future. What clients really want is the list of files that
are presented to the go compiler, so that they can parse
and type-check them as if they were the compiler instead.

Eliminate all this awkwardness by dropping -cgo and adding
a new -compiled that populates a new CompiledGoFiles list.

      cmd/go: split go mod into multiple subcommands · 6121987a
      Russ Cox authored 
      The current "go mod" command does too many things.
The design is unclear.

It looks like "everything you might want to do with modules"
which causes people to think all module operations go through
"go mod", which is the opposite of the seamless integration we're
going for. In particular too many people think "go mod -require"
and "go get" are the same.

It does make sense to put the module-specific functionality
under "go mod", but not as flags. Instead, split "go mod" into
multiple subcommands:

	go mod edit   # old go mod -require ...
	go mod fix    # old go mod -fix
	go mod graph  # old go mod -graph
	go mod init   # old go mod -init
	go mod tidy   # old go mod -sync
	go mod vendor # old go mod -vendor
	go mod verify # old go mod -verify

Splitting out the individual commands makes both the docs
and the implementations dramatically easier to read.
It simplifies the command lines
(go mod -init -module m is now 'go mod init m')
and allows command-specific flags.

We've avoided subcommands in the go command to date, and we
should continue to avoid adding them unless it really makes
the experience significantly better. In this case, it does.

Creating subcommands required some changes in the core
command-parsing and help logic to generalize from one
level to multiple levels.

As part of having "go mod init" be a separate command,
this CL changes the failure behavior during module initialization
to be delayed until modules are actually needed.
Initialization can still happen early, but the base.Fatalf
is delayed until something needs to use modules.
This fixes a bunch of commands like 'go env' that were
unhelpfully failing with GO111MODULE=on when not in a
module directory.

Fixes #26432.
Fixes #26581.
Fixes #26596.
Fixes #26639.
