$ pprof -http=:8080 foobar.lan:31571/debug/pprof/profile?seconds=5
Fetching profile over HTTP from http://foobar.lan:31571/debug/pprof/profile?seconds=5
Local symbolization failed for foobar-3.61.0-4290 (deleted): stat /local/foobar/bin/foobar-3.61.0-4290 (deleted): no such file or directory
Some binary filenames not available. Symbolization may be incomplete.
Try setting PPROF_BINARY_PATH to the search path for local binaries.
Saved profile in /home/marko/pprof/pprof.foobar-3.61.0-4290 (deleted).samples.cpu.002.pb.gz
Notice "(deleted)" in binary name and in profile name.
This is because binary for a running service was rewritten (deleted, moved, does not matter) and /proc/pid/maps gives you name of the binary with string "(deleted)" appended to tell you that the file was removed (inode is different or unexisting).
I propose for runtime/pprof to cleanup filename and remove "(deleted)" if it exists.
It is not needed and it would be easier to put the same file locally and get symbols and source code.
Initially I've opened an issue for pprof (google/pprof#386), but they've decided that it would be better to fix it in Go.

What version of Go are you using (
go version
)?2c01b7d
Does this issue reproduce with the latest release?
Yes
What operating system and processor architecture are you using (
go env
)?4.15.0-22-generic
Ubuntu 18.04 LTS
What did you do?
Run a service with "net/http/pprof" and tried using pprof (https://github.com/google/pprof/) to profile this service.
As I said in google/pprof#386, this is what I got:
Notice "(deleted)" in binary name and in profile name.
