From b2f2446b46bf02821d90ebedadae2bf7ae0e880e Mon Sep 17 00:00:00 2001 From: Taras Madan Date: Mon, 5 Sep 2022 14:27:54 +0200 Subject: go.mod, vendor: update (#3358) * go.mod, vendor: remove unnecessary dependencies Commands: 1. go mod tidy 2. go mod vendor * go.mod, vendor: update cloud.google.com/go Commands: 1. go get -u cloud.google.com/go 2. go mod tidy 3. go mod vendor * go.mod, vendor: update cloud.google.com/* Commands: 1. go get -u cloud.google.com/storage cloud.google.com/logging 2. go mod tidy 3. go mod vendor * go.mod, .golangci.yml, vendor: update *lint* Commands: 1. go get -u golang.org/x/tools github.com/golangci/golangci-lint@v1.47.0 2. go mod tidy 3. go mod vendor 4. edit .golangci.yml to suppress new errors (resolved in the same PR later) * all: fix lint errors hash.go: copy() recommended by gosimple parse.go: ent is never nil verifier.go: signal.Notify() with unbuffered channel is bad. Have no idea why. * .golangci.yml: adjust godot rules check-all is deprecated, but still work if you're hesitating too - I'll remove this commit --- vendor/github.com/google/pprof/profile/encode.go | 11 +++++++- .../google/pprof/profile/legacy_profile.go | 30 ++++++++++++---------- vendor/github.com/google/pprof/profile/merge.go | 22 ++++++++-------- vendor/github.com/google/pprof/profile/profile.go | 9 +++++++ 4 files changed, 47 insertions(+), 25 deletions(-) (limited to 'vendor/github.com/google/pprof/profile') diff --git a/vendor/github.com/google/pprof/profile/encode.go b/vendor/github.com/google/pprof/profile/encode.go index 1e84c72d4..96aa271e5 100644 --- a/vendor/github.com/google/pprof/profile/encode.go +++ b/vendor/github.com/google/pprof/profile/encode.go @@ -17,6 +17,7 @@ package profile import ( "errors" "sort" + "strings" ) func (p *Profile) decoder() []decoder { @@ -252,6 +253,14 @@ func (p *Profile) postDecode() error { } else { mappings[m.ID] = m } + + // If this a main linux kernel mapping with a relocation symbol suffix + // ("[kernel.kallsyms]_text"), extract said suffix. + // It is fairly hacky to handle at this level, but the alternatives appear even worse. + if strings.HasPrefix(m.File, "[kernel.kallsyms]") { + m.KernelRelocationSymbol = strings.ReplaceAll(m.File, "[kernel.kallsyms]", "") + } + } functions := make(map[uint64]*Function, len(p.Function)) @@ -308,7 +317,7 @@ func (p *Profile) postDecode() error { if l.strX != 0 { value, err = getString(p.stringTable, &l.strX, err) labels[key] = append(labels[key], value) - } else if l.numX != 0 { + } else if l.numX != 0 || l.unitX != 0 { numValues := numLabels[key] units := numUnits[key] if l.unitX != 0 { diff --git a/vendor/github.com/google/pprof/profile/legacy_profile.go b/vendor/github.com/google/pprof/profile/legacy_profile.go index 0c8f3bb5b..9ba9a77c9 100644 --- a/vendor/github.com/google/pprof/profile/legacy_profile.go +++ b/vendor/github.com/google/pprof/profile/legacy_profile.go @@ -295,11 +295,12 @@ func get64b(b []byte) (uint64, []byte) { // // The general format for profilez samples is a sequence of words in // binary format.
