From 7165c23237d4c2716015bbef397f6f65435cdd67 Mon Sep 17 00:00:00 2001 From: Changqing Li Date: Wed, 6 Mar 2024 22:49:08 -0800 Subject: go: filter out build specific path from the linker flags patch 0007-exec.go-do-not-write-linker-flags-into-buildids.patch removes linker flags from buildids for not breaking reproducibility, but it seems that this will make go not rebuild when linker flag changes, Refer [1]. So remove this oe-specific patch, and change to filter out build specific path from the linker flags [1] https://github.com/golang/go/issues/63760 (From OE-Core rev: 6873c6cb000b24c1badd0fb8b5cd2d0a31a63096) Signed-off-by: Changqing Li Signed-off-by: Richard Purdie --- meta/recipes-devtools/go/go-1.22.0.inc | 2 +- ...ter-out-build-specific-paths-from-linker-.patch | 61 ++++++++++++++++++++++ 2 files changed, 62 insertions(+), 1 deletion(-) create mode 100644 meta/recipes-devtools/go/go/0001-exec.go-filter-out-build-specific-paths-from-linker-.patch (limited to 'meta') diff --git a/meta/recipes-devtools/go/go-1.22.0.inc b/meta/recipes-devtools/go/go-1.22.0.inc index 230ada5e4b..5b94051fc2 100644 --- a/meta/recipes-devtools/go/go-1.22.0.inc +++ b/meta/recipes-devtools/go/go-1.22.0.inc @@ -11,8 +11,8 @@ SRC_URI += "\ file://0004-make.bash-override-CC-when-building-dist-and-go_boot.patch \ file://0005-cmd-dist-separate-host-and-target-builds.patch \ file://0006-cmd-go-make-GOROOT-precious-by-default.patch \ - file://0007-exec.go-do-not-write-linker-flags-into-buildids.patch \ file://0008-src-cmd-dist-buildgo.go-do-not-hardcode-host-compile.patch \ file://0009-go-Filter-build-paths-on-staticly-linked-arches.patch \ + file://0001-exec.go-filter-out-build-specific-paths-from-linker-.patch \ " SRC_URI[main.sha256sum] = "4d196c3d41a0d6c1dfc64d04e3cc1f608b0c436bd87b7060ce3e23234e1f4d5c" diff --git a/meta/recipes-devtools/go/go/0001-exec.go-filter-out-build-specific-paths-from-linker-.patch b/meta/recipes-devtools/go/go/0001-exec.go-filter-out-build-specific-paths-from-linker-.patch new file mode 100644 index 0000000000..c5bf28f54a --- /dev/null +++ b/meta/recipes-devtools/go/go/0001-exec.go-filter-out-build-specific-paths-from-linker-.patch @@ -0,0 +1,61 @@ +From 083b5c74b12a1abeb11dd7f58a1cb1593d0000c0 Mon Sep 17 00:00:00 2001 +From: Changqing Li +Date: Tue, 27 Feb 2024 18:06:51 +0800 +Subject: [PATCH] exec.go: filter out build-specific paths from linker flags + +The flags can contain build-specific paths, breaking reproducibility. +Filter out options that have build-specific paths. + +Upstream-Status: Inappropriate [ Not perfect for upstream ] + +Signed-off-by: Changqing Li +--- + src/cmd/go/internal/work/exec.go | 25 ++++++++++++++++++++++++- + 1 file changed, 24 insertions(+), 1 deletion(-) + +diff --git a/src/cmd/go/internal/work/exec.go b/src/cmd/go/internal/work/exec.go +index cde867b..e3ce17d 100644 +--- a/src/cmd/go/internal/work/exec.go ++++ b/src/cmd/go/internal/work/exec.go +@@ -1358,6 +1358,29 @@ func (b *Builder) linkActionID(a *Action) cache.ActionID { + return h.Sum() + } + ++func filterLinkerFlags(flags []string) []string { ++ var newflags []string ++ var skipflag bool ++ skipflag = false ++ for i, flag := range flags { ++ if skipflag == true { ++ skipflag = false ++ continue ++ } ++ if strings.HasPrefix(flag, "--sysroot") || strings.HasPrefix(flag, "-fmacro-prefix-map") || strings.HasPrefix(flag, "-fdebug-prefix-map") || strings.HasPrefix(flag, "-ffile-prefix-map") || strings.HasPrefix(flag, "-fcanon-prefix-map") || strings.HasPrefix(flag, "-fprofile-prefix-map") || strings.HasPrefix(flag, "-Wl,-rpath-link"){ ++ continue ++ } else if strings.HasPrefix(flag, "-extldflags") { ++ skipflag = true ++ newflags = append(newflags, flag) ++ var filterd_Extldflags []string = filterLinkerFlags(strings.Split(flags[i+1], " ")) ++ newflags = append(newflags, strings.Join(filterd_Extldflags, " ")) ++ } else { ++ newflags = append(newflags, flag) ++ } ++ } ++ return newflags ++} ++ + // printLinkerConfig prints the linker config into the hash h, + // as part of the computation of a linker-related action ID. + func (b *Builder) printLinkerConfig(h io.Writer, p *load.Package) { +@@ -1368,7 +1391,7 @@ func (b *Builder) printLinkerConfig(h io.Writer, p *load.Package) { + case "gc": + fmt.Fprintf(h, "link %s %q %s\n", b.toolID("link"), forcedLdflags, ldBuildmode) + if p != nil { +- fmt.Fprintf(h, "linkflags %q\n", p.Internal.Ldflags) ++ fmt.Fprintf(h, "linkflags %q\n", filterLinkerFlags(p.Internal.Ldflags)) + } + + // GOARM, GOMIPS, etc. +-- +2.25.1 + -- cgit v1.2.3-54-g00ecf
