However, I keep seeing weird "app error: uninitialized fiber (FiberError)". I spent a few hours (ouch) tracking down to a simple case. Suppose I have a Rack app which has `Rainbows.sleep` inside a each block: https://gist.github.com/1536857 (I am running Ruby 1.9.3) class Weird def call env=nil [1].each{ # if you comment out the each block, then it works Rainbows.sleep 2 } [200, {}, ["ok\n"]] end end Then `run Weird.new` would always cause app error: uninitialized fiber (FiberError) But if I took out the each block inside Weird#call, such like: class Weird def call env=nil Rainbows.sleep 2 [200, {}, ["ok\n"]] end end Then it works fine. Moreover, if I run the app like this: run lambda{ |env| Weird.new.call } Then both with or without the each block would work. Could you please explain this for me? Or is it a bug somewhere? Thanks!! _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 6+ messages in thread

This looks like a Ruby bug, possibly related to combining Fibers with fork()... Can you reproduce this with zbatery? (zbatery is Rainbows!, without fork()), just s/rainbows/zbatery/ in the command-line).

I can reproduce this under zbatery as well, so I guess this is not related to fork()? My ruby and gem versions: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0] zbatery (4.1.2) rainbows (4.3.1) unicorn (4.1.1) cool.io (1.1.0) I am not sure if I should be happy if this is really a ruby's bug. I thought I just couldn't figure out how do fibers work, looking through a lot of sources and doing a lot of experiments. _______________________________________________ Rainbows! mailing list - rainbows-talk@rubyforge.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 6+ messages in thread

My ruby and gem versions: > > ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0] It may be an issue with LLVM/GCC on your platform, I've seen several issues on the ruby-core list related to that setup. Maybe recompiling Ruby (and all extensions) with a non-LLVM version of GCC will solve this. > I am not sure if I should be happy if this is really a ruby's bug. > I thought I just couldn't figure out how do fibers work, looking > through a lot of sources and doing a lot of experiments. Can you reproduce the issue on a GNU/Linux system? I cannot support non-Free platforms, anyways. _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 6+ messages in thread

I'll try to recompile Ruby (and all extensions) tomorrow. (I really need to sleep now) It seems now Apple does not provide a non-LLVM GCC now. My /usr/bin/gcc is a link to llvm-gcc-4.2. > Can you reproduce the issue on a GNU/Linux system? > I cannot support non-Free platforms, anyways. I should have thought this. Just tried on my Arch Linux: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux] I can't reproduce that on the machine. That's a good news. We're deploying to Linux anyway. Thanks! (I am not sure how to narrow this down further to file a bug on Ruby's issue tracker. Maybe I'll just show them what I have now) _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 6+ messages in thread

Just want to let you know, after trying GCC 4.6 without LLVM involved and reinstalling all binary extensions, I can no longer reproduce this. What's amazing is, when I switch back to the old Ruby which is compiled with Apple's llvm-gcc, I can't reproduce that either! O_o Maybe it's restarting the computer would really solve everything, or I just did something wrong somewhere... Then I guess I shouldn't file a bug for this.
