      all: remove nacl (part 3, more amd64p32) · 03ef105d
      Brad Fitzpatrick authored
      Part 1: CL 199499 (GOOS nacl)
      Part 2: CL 200077 (amd64p32 files, toolchain)
      Part 3: stuff that arguably should've been part of Part 2, but I forgot
              one of my grep patterns when splitting the original CL up into
              two parts.
      
      This one might also have interesting stuff to resurrect for any future
      x32 ABI support.

      cmd/go: forbid module pattern 'all' when outside a module · 68395a66
      Jay Conrod authored
      Also, in cmd/doc, avoid calling 'go list -m all' when in module mode
      outside a module since it's now an error.

      cmd/compile: walk progs to generate debug_lines data · 46b75578
      Jeremy Faller authored
      Walking the progs is simpler than using the is_stmt symbol shenanigans.
      This is a reinstatement of CL 196661, which was rolled back due to tests
      failing. Unlike that original CL, this change should output the same
      debug_lines data the original approach wrote.
      
      The stats for JUST this CLC, note teh small speedup in compilation, and
      the lack of difference in binary size.

      encoding/json: support TextUnmarshaler for map keys with string underlying types · fb9af841
      Cuong Manh Le authored
      When unmarshaling to a map, the map's key type must either be a string,
      an integer, or implement encoding.TextUnmarshaler. But for a user
      defined type, reflect.Kind will not distinguish between the static type
      and the underlying type. In:
      
      	var x MyString = "x"
      	t := reflect.TypeOf(x)
      	println(t.Kind() == reflect.String)
      
      the Kind of x is still reflect.String, even though the static type of x
      is MyString.
      
      Moreover, checking for the map's key type is a string occurs first, so
      even if the map key type MyString implements encoding.TextUnmarshaler,
      it will be ignored.
      
      To fix the bug, check for encoding.TextUnmarshaler first.

      cmd/go: forbid resolving import to modules when outside of a module · 3322f3e0
      Jay Conrod authored
      When in module mode outside of any module, 'go build' and most other
      commands will now report an error instead of resolving a package path
      to a module.
      
      Previously, most commands would attempt to find the latest version of
      a module providing the package. This could be very slow if many
      packages needed to be resolved this way. Since there is no go.mod file
      where module requirements can be saved, it's a repeatedly slow and
      confusing experience.
      
      After this change, 'go build' and other commands may still be used
      outside of a module on packages in std and source files (.go
      arguments) that only import packages in std. Listing any other package
      on the command line or importing a package outside std will cause an
      error.
      
      'go get' is exempted from the new behavior, since it's expected that
      'go get' resolves paths to modules at new versions.

      go/build: import packages in module mode when GO111MODULE is "on" · 99b9ee3e
      Jay Conrod authored
      go/build.Import locates package dirctories using 'go list' when in
      module mode (finding, downloading, and extracting modules is
      complicated, so go/build does not handle it).
      
      Previously, Import used 'go list' if GO111MODULE was not explicitly
      off and a go.mod file was present (plus some other conditions). With
      this change, if GO111MODULE is "on", a go.mod file does not need to be
      present.

      cmd/go: eliminate redundancy in import error messages · 32b6eb80
      Jay Conrod authored
      This change introduces a new interface, load.ImportPathError. An error
      may satisfy this by providing an ImportPath method and including the
      import path in its error text. modload.ImportMissingError satisfies
      this interface. load.ImportErrorf also provides a convenient way to
      create an error satisfying this interface with an arbitrary message.
      
      When load.PackageError formats its error text, it may omit the last
      path on the import stack if the wrapped error satisfies
      ImportPathError and has a matching path.
      
      To make this work, PackageError.Err is now an error instead of a
      string. PackageError.MarshalJSON will write Err as a string for
      'go list -json' output.
      
      When go/build.Import invokes 'go list' in module mode, it now runs
      with '-e' and includes '.Error' in the output format instead of
      expecting the error to be in the raw stderr text. If a package error
      is printed and a directory was not found, the error will be returned
      without extra decoration.

      cmd/go/internal/modfile: remove preceding empty lines when setting require · 4c7a8d63
      Jason A. Donenfeld authored
      When rewriting a go.mod file, we currently sort all of the require
      lines in a block. The way the parser works is that it considers
      preceding blank lines to be empty comment lines, and preceding empty
      comment lines are "owned" by their adjoining line. So when we go to sort
      them, the empty lines follow around each sorted entry, which doesn't
      make a whole lot of sense, since usually vertical space is inserted to
      show sections, and if things get moved around by sorting, those sections
      are no longer meaningful. This all results in one especially troublesome
      edge case: blank lines between a block opening ("require (") and the
      first block line ("golang.org/x/sys ...") are not treated the same way
      and are rewritten out of existence.
      
      Here's an example of the behavior this fixes.
      
      Starting input file:
      
          require (
              golang.zx2c4.com/wireguard master
      
              golang.org/x/crypto latest
              golang.org/x/net latest
              golang.org/x/sys latest
              golang.org/x/text latest
      
              github.com/lxn/walk latest
              github.com/lxn/win latest
          )
      
      Now we run this through `GOPROXY=direct go get -d`:
      
          require (
      
              github.com/lxn/walk v0.0.0-20190619151032-86d8802c197a
              github.com/lxn/win v0.0.0-20190716185335-d1d36f0e4f48
      
              golang.org/x/crypto v0.0.0-20190820162420-60c769a6c586
              golang.org/x/net v0.0.0-20190813141303-74dc4d7220e7
              golang.org/x/sys v0.0.0-20190813064441-fde4db37ae7a
              golang.org/x/text v0.3.2
              golang.zx2c4.com/wireguard v0.0.20190806-0.20190822065259-3cedc22d7b49
          )
      
      Notice how the blank lines before lxn/walk and x/crypto were preserved.
      
      Finally, we have this be rewritten yet again with a call to `go build`:
      
          require (
              github.com/lxn/walk v0.0.0-20190619151032-86d8802c197a
              github.com/lxn/win v0.0.0-20190716185335-d1d36f0e4f48
      
              golang.org/x/crypto v0.0.0-20190820162420-60c769a6c586
              golang.org/x/net v0.0.0-20190813141303-74dc4d7220e7
              golang.org/x/sys v0.0.0-20190813064441-fde4db37ae7a
              golang.org/x/text v0.3.2
              golang.zx2c4.com/wireguard v0.0.20190806-0.20190822065259-3cedc22d7b49
          )
      
      In this final resting point, the first blank line has been removed.
      
      The discrepancy between those two last stages are especially bothersome,
      because it makes for lots of dirty git commits and file contents
      bouncing back and forth.
      
      This commit fixes the problem as mentioned above, getting rid of those
      preceding blank lines. The output in all cases looks as it should, like
      this:
      
          require (
              github.com/lxn/walk v0.0.0-20190619151032-86d8802c197a
              github.com/lxn/win v0.0.0-20190716185335-d1d36f0e4f48

      cmd/go: fail if a test binary exits with no output · 1fba10c9
      Daniel Martí authored
      For example, if a test calls os.Exit(0), that could trick a 'go test'
      run into not running some of the other tests, and thinking that they all
      succeeded. This can easily go unnoticed and cause developers headaches.
      
      Add a simple sanity check as part of 'go test': if the test binary
      succeeds and doesn't print anything, we should error, as something
      clearly went very wrong.
      
      This is done by inspecting each of the stdout writes from the spawned
      process, since we don't want to read the entirety of the output into a
      buffer. We need to introduce a "buffered" bool var, as there's now an
      io.Writer layer between cmd.Stdout and &buf.
      
      A few TestMain funcs in the standard library needed fixing, as they
      returned without printing anything as a means to skip testing the entire
      package. For that purpose add testenv.MainMust, which prints a warning
      and prints SKIP, similar to when -run matches no tests.
      
      Finally, add tests for both os.Exit(0) and os.Exit(1), both as part of
      TestMain and as part of a single test, and test that the various stdout
      modes still do the right thing.
      
      Fixes #29062.

      cmd/asm: add s390x branch-on-count instructions · 38c4a737
      Michael Munday authored
      The branch-on-count instructions on s390x decrement the input
      register and then compare its value to 0. If not equal the branch
      is taken.
      
      These instructions are useful for implementing loops with a set
      number of iterations (which might be in a register).
      
      For example, this for loop:
      
      	for i := 0; i < n; i++ {
      		... // i is not used or modified in the loop
      	}
      
      Could be implemented using this assembly:
      
      	MOVD  Rn, Ri
      loop:
      	...
      	BRCTG Ri, loop
      
      Note that i will count down from n in the assembly whereas in the
      original for loop it counted up to n which is why we can't use i
      in the loop.
      
      These instructions will only be used in hand-written codegen and
      assembly for now since SSA blocks cannot currently modify values.
      We could look into this in the future though.

      cmd/go: suppress more errors in package-to-module loading · 421d35cf
      Bryan C. Mills authored
      In CL 197059, I suppressed errors if the target package was already found.
      However, that does not cover the case of passing a '/v2' module path to
      'go get' when the module does not contain a package at its root.
      
      This CL is a minimal fix for that case, intended to be backportable to 1.13.
      
      (Longer term, I intend to rework the version-validation check to treat
      all mismatched paths as ErrNotExist.)

      all: remove the nacl port (part 1) · a38a917a
      Brad Fitzpatrick authored
      You were a useful port and you've served your purpose.
      Thanks for all the play.
      
      A subsequent CL will remove amd64p32 (including assembly files and
      toolchain bits) and remaining bits. The amd64p32 removal will be
      separated into its own CL in case we want to support the Linux x32 ABI
      in the future and want our old amd64p32 support as a starting point.
