Justin Ross updated PROTON-1063:
--------------------------------
Fix Version/s: (was: 0.13.0)
> ruby: ruby reactor holds GVL in process
> ---------------------------------------
>
> Key: PROTON-1063
> URL: https://issues.apache.org/jira/browse/PROTON-1063
> Project: Qpid Proton
> Issue Type: Bug
> Components: ruby-binding
> Affects Versions: 0.10
> Reporter: Alan Conway
> Assignee: Alan Conway
>
> Ruby has a global lock the GVL, like python's GIL.
> The ruby binding Reactor#process blocks in pn_reactor_process while holding
> the lock, blocking all other ruby threads.
> This is the same issue as PROTON-752, but it was only fixed for messenger,
> not for the reactor.
> The fix is more complex, we can't simply call pn_reactor_process in
> rb_thread_call_without_gvl() because it calls handler functions that call
> back into ruby. We need to isolate just the blocking IO code in without_gvl
> and restore the lock before handlers call back into ruby.
