------------------------------------
Summary: Ruby: Cproton calls don't unlock the GIL for blocking /
long-running operations
Key: PROTON-752
URL: https://issues.apache.org/jira/browse/PROTON-752
Project: Qpid Proton
Issue Type: Bug
Components: ruby-binding
Affects Versions: 0.8
Reporter: Dominic Evans
Priority: Minor
Currently the I/O-style calls to the Cproton methods don't unlock the Ruby GIL,
impacting performance as other Threads could be given time on the interpreter
whilst the extension code is running.
Depending on Ruby version this is simply a matter of wrapping the calls in
rb_thread_call_without_gvl (Ruby 2.x +) or rb_thread_blocking_region (Ruby
1.9.x). On Ruby 1.8 I'm not sure if you can enable this, but its my
understanding that RHEL requires continued support for 1.8, so some #define
work would be needed to perform a no-op on that version.
