<div dir="ltr">Thanks Benoit!<div><br></div><div>Now, is it really necessary to prevent multithreaded when interfacing Ruby and R? I understand that since R is not multithreaded, calling it from multiple threads will cause weird problems, but if the programmer is careful and say, only calls R from the same Ruby thread, everything should work fine, no? If this is the case, then could there be a flag to allow multithreaded applications even in the presence of R?</div><div><br></div><div>Thanks</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Jun 14, 2018 at 2:38 PM Benoit Daloze <<a href="mailto:eregontp@gmail.com">eregontp@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Note that one way to avoid MinitTest creating multiple threads is to give it `N=0` like<div><br></div><div>$ N=0 ruby -Xsingle_threaded=true mytest.rb</div><div><br></div><div>I checked and this seems to work fine with GraalVM RC2 and minitest 5.10.1 (bundled) and 5.11.3 (latest).</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jun 14, 2018 at 5:25 PM, Rodrigo Botafogo <span dir="ltr"><<a href="mailto:rodrigo.a.botafogo@gmail.com" target="_blank">rodrigo.a.botafogo@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hello,<div><br></div><div>I'm trying to set up testing for my polyglot lib and I'm having a hard time.
