This prevents the building +of a package in GOPATH for later staging into GOROOT. + +This patch adds support for the environment variable +GOPATH_OMIT_IN_ACTIONID. If present, path name +embedding is disabled. + +Second, if cgo is enabled, the build ID for cgo-related +packages will include the current value of the environment +variables for invoking the compiler (CC, CXX, FC) and +any CGO_xxFLAGS variables. Only if the settings used +during a compilation exactly match, character for character, +the values used for compiling runtime/cgo or any other +cgo-enabled package being imported, will the tool +decide that the imported package is up-to-date. + +This is done to help ensure correctness, but is overly +simplistic and effectively prevents the reuse of built +artifacts that use cgo (or shared runtime, which includes +runtime/cgo). + +This patch filters out all compiler flags except those +beginning with '-m'. The default behavior can be restored +by setting the CGO_PEDANTIC environment variable. + +Adapted to Go 1.13 from patches originally submitted to +the meta/recipes-devtools/go tree by +Matt Madison . + +Signed-off-by: Alexander J Kube +--- + src/cmd/go/internal/envcmd/env.go | 2 +- + src/cmd/go/internal/work/exec.go | 66 ++++++++++++++++++++++--------- + 2 files changed, 49 insertions(+), 19 deletions(-) + +--- a/src/cmd/go/internal/envcmd/env.go ++++ b/src/cmd/go/internal/envcmd/env.go +@@ -156,7 +156,7 @@ func ExtraEnvVars() []cfg.EnvVar { + func ExtraEnvVarsCostly() []cfg.EnvVar { + var b work.Builder + b.Init() +- cppflags, cflags, cxxflags, fflags, ldflags, err := b.CFlags(&load.Package{}) ++ cppflags, cflags, cxxflags, fflags, ldflags, err := b.CFlags(&load.Package{}, false) + if err != nil { + // Should not happen - b.CFlags was given an empty package. + fmt.Fprintf(os.Stderr, "go: invalid cflags: %v\n", err) +--- a/src/cmd/go/internal/work/exec.go ++++ b/src/cmd/go/internal/work/exec.go +@@ -32,6 +32,8 @@ import ( + "time" + ) + ++var omitGopath = os.Getenv("GOPATH_OMIT_IN_ACTIONID") != "" ++ + // actionList returns the list of actions in the dag rooted at root + // as visited in a depth-first post-order traversal. + func actionList(root *Action) []*Action { +@@ -208,7 +210,7 @@ func (b *Builder) buildActionID(a *Actio + // Assume b.WorkDir is being trimmed properly. + // When -trimpath is used with a package built from the module cache, + // use the module path and version instead of the directory. +- if !p.Goroot && !cfg.BuildTrimpath && !strings.HasPrefix(p.Dir, b.WorkDir) { ++ if !p.Goroot && !omitGopath && !cfg.BuildTrimpath && !strings.HasPrefix(p.Dir, b.WorkDir) { + fmt.Fprintf(h, "dir %s\n", p.Dir) + } else if cfg.BuildTrimpath && p.Module != nil { + fmt.Fprintf(h, "module %s@%s\n", p.Module.Path, p.Module.Version) +@@ -224,13 +226,13 @@ func (b *Builder) buildActionID(a *Actio + } + if len(p.CgoFiles)+len(p.SwigFiles) > 0 { + fmt.Fprintf(h, "cgo %q\n", b.toolID("cgo")) +- cppflags, cflags, cxxflags, fflags, ldflags, _ := b.CFlags(p) +- fmt.Fprintf(h, "CC=%q %q %q %q\n", b.ccExe(), cppflags, cflags, ldflags) ++ cppflags, cflags, cxxflags, fflags, ldflags, _ := b.CFlags(p, true) ++ fmt.Fprintf(h, "CC=%q %q %q %q\n", b.ccExe(true), cppflags, cflags, ldflags) + if len(p.CXXFiles)+len(p.SwigFiles) > 0 { +- fmt.Fprintf(h, "CXX=%q %q\n", b.cxxExe(), cxxflags) ++ fmt.Fprintf(h, "CXX=%q %q\n", b.cxxExe(true), cxxflags) + } + if len(p.FFiles) > 0 { +- fmt.Fprintf(h, "FC=%q %q\n", b.fcExe(), fflags) ++ fmt.Fprintf(h, "FC=%q %q\n", b.fcExe(true), fflags) + } + // TODO(rsc): Should we include the SWIG version or Fortran/GCC/G++/Objective-C compiler versions?
