1989079 - raptor-gecko-profile Critical: Encountered an exception during profile symbolication on ARM Mac

Status: NEW

(Testing :: Raptor, defect, P3)

Description

[Abhishek Nimalan [:animalan]]

When running a raptor test with --gecko-profile flag (ex. ./mach raptor -t amazon --gecko-profile) on an M4 Mac, the following error occurred:

0:18:29 CRITICAL -  raptor-gecko-profile Critical: Encountered an exception during profile symbolication

Logging the exception gives:

20:18:29     INFO -  raptor-gecko-profile Info: [Errno 86] Bad CPU type in executable: '/Users/animalan/firefox/testing/mozbase/mozgeckoprofiler/mozgeckoprofiler/dump_syms_mac'

The issue seems to be due to the dump_syms_mac binary being an x86-64 executable.

file /Users/animalan/firefox/testing/mozbase/mozgeckoprofiler/mozgeckoprofiler/dump_syms_mac

/Users/animalan/firefox/testing/mozbase/mozgeckoprofiler/mozgeckoprofiler/dump_syms_mac: Mach-O 64-bit executable x86_64

A workaround for ARM Macs is just installing Rosetta i.e. running something like:

softwareupdate --install-rosetta --agree-to-license
xattr -dr com.apple.quarantine /Users/animalan/firefox/testing/mozbase/mozgeckoprofiler/mozgeckoprofiler/dump_syms_mac
chmod +x /Users/animalan/firefox/testing/mozbase/mozgeckoprofiler/mozgeckoprofiler/dump_syms_mac

Including a static binary directly into source seems problematic. Ideally this binary should be removed or dealt with more dynamically (possibly in bug 1970961). The dump_syms Rust rewrite (which offers Apple ARM builds) might be useful here.

With Bug 1970961 we may be able to remove this binary
