[Bug 1743598] [NEW] 'go tool trace' doesn't show trace

[Jakub Matys]

Public bug reported:

DESCRIPTION:
Command 'go tool trace <trace-file>' starts a web server and opens a browser. Web page on path /trace should contain trace graphs but is blank. JS console showed 404 error. I've found that corresponding handler tries open file at $GOROOT/misc/trace/trace_viewer_lean.html (line /usr/lib/go-1.8/src/cmd/trace/trace.go:130). According to comment at https://groups.google.com/d/msg/golang-nuts/B7sZrDhhWfw/_aQ69qJoDQAJ the directory $GOROOT/misc is probably deleted during build of the package. I've fixed the bug by creating /usr/lib/go-1.8/misc/trace by hand and copying appropriate file from Go sources. 

PACKAGES:
golang-1.7-go (1.7.4-2ubuntu1)
golang-1.8-go (1.8.3-2ubuntu1)
golang-1.9-go (1.9.1-2ubuntu1)
