1168103 - Execution cannot reach the expression "?unknown?" inside this statement in jsfriendapi.cpp

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Sylvestre Ledru [:Sylvestre]]

In https://dxr.mozilla.org/mozilla-central/source/js/src/jsfriendapi.cpp?from=%20%20%20%20jsfriendapi.cpp#782
This expression is useless:
value ? value : "?unknown?",
As we already check that 'value' is not NULL a few lines upper.

Hi, I would like to fix this bug. I have cloned the repository and fixed the source code.

I just replaced line 782 as such:   ' value ? value : "?unknown?", '  => ' value, '

Hi, I updated the line since value is already defined based off the IF statement.

Mayank, Phil is a sheriff (folks who are in charge of managing the commit and uplift of the patches). 
Terrence is probably a better reviewer.

Oh. I did git blame because I didn't have mercurial installed. I will install it tonight.

According to mercurial, evilpie touched this code most recently.

How can I test this on the try server?

I don't think this is needed. The patch is simple enough!

I just noticed that you used tabs instead of spaces. js/src uses 4 spaces for indention, the rest of Gecko usually uses 2 spaces, but never tabs.
