What is the rubyracer gem being used for? Can we remove it?

waj commented 9 years ago

That gem provides the interface with V8, the Javascript engine. So strange it's failing for you. It never crashed like that in our servers (so far...).

Seems like there is a new version of the Gem (0.10.1) but I didn't checked the changelog. Could you please test upgrading the version to see if that helps?

Hey Juan,

I updated the ruby racer to (0.10.1) but I still get the same segfault. It happens very often like every 2 or 3 calls. FYI the segfault is happening on this line: /gems/therubyracer-0.10.1/lib/v8/context.rb:100 in the Enter() function which also looks strange to me.

I know that the Ruby Racer has some native extensions so I'll see if anyone else has had this problem on Ubuntu.

This maybe related: I haven't tried the solution mentioned at the bottom of the comments yet though: https://github.com/cowboyd/therubyracer/issues/96

Note: I just tried the solution in the issue above but it still segfaults:

{{{

bundle show libv8
