1273306 - Analyzing a profile triggers multiple instances of this error in my terminal: /usr/bin/addr2line: '': No such file

Status: RESOLVED FIXED

(Core :: Gecko Profiler, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Download Gecko Profiler add-on from:
  https://github.com/bgirard/Gecko-Profiler-Addon/blob/master/geckoprofiler-signed.xpi?raw=true
 2. Install it in a fresh Firefox profile.
 3. Start Firefox using that profile, from the terminal.
 4. Analyze anything (e.g. just start up and hit Ctrl+Shift+2
 5. Watch your terminal output.

ACTUAL RESULTS:
Multiple instances of this error get printed to my command line,  while the profile is being analyzed (while messages like "Resolving symbols for library [whatever]" are being displayed in the browser).
> /usr/bin/addr2line: '': No such file

In other words: it looks like we're invoking addr2line with an empty filename, or something.

EXPECTED RESULTS: We shouldn't be invoking addr2line with an empty filename.

I'm using Ubuntu 16.04 with Firefox Nightly 49.0a1 (2016-05-15)

I think I've seen this before and IIRC it's not a critical issue. The gecko profiler doesn't get a lot of time on Linux sadly. Ideally we'd check why the symbolication script is assigning symbols an empy string library tell it to ignore resolving symbols for that.

Fwiw, the new cleopatra is doing basically the same thing. On the console log:

  Failed to symbolicate library : Error: Don't know where library   is stored.

(Hm. That's odd. There are 3 spaces between "library   is". I'd expect 2 for an empty string.)

Obsolete, no more add-on.
