[Gluster-devel] Languages (was Re: Proposal for GlusterD-2.0)

[Luis Pabón]

I think the real question is, Why do we depend on core files?  What does 
it provide?  If we rethink how we may do debugging, we may realize that 
we only require core files because we are used to it and it is familiar 
to us.  Now, I am not saying that core files are not useful, but I am 
saying that we may be able to do most of the necessary debugging by 
other means.

For example, debugging systems running OpenStack Swift which uses Python 
stack traces has been much easier than analyzing C core files.  Just my 
experience.

I would not say that because Go, Java, Ruby, or Python do not create 
core files, that it would be hard to debug.  Instead we need to learn 
new ways of debugging.  Just my $0.02 :-)
