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 <matt@madison.systems>. - -Signed-off-by: Alexander J Kube <alexander.j.kube@gmail.com> ---- - 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 -@@ -157,7 +157,7 @@ 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 -@@ -37,6 +37,8 @@ import ( - "cmd/go/internal/trace" - ) - -+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 { -@@ -228,7 +230,7 @@ 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) -@@ -247,13 +249,13 @@ 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?
