Shouldn't the option "UseThreadAbortForSyncRaise" be called "...ForASyncRaise"? I think that Thread.raise with no arguments should just inject a RuntimeError with no message as if $! were nil; this makes more sense than failing. Trying to reference a "current exception" in another thread is a scary operation even if that's what MRI is doing.
Other than that, changes look really nice. But anyone thinking of using this functionality should read Charlie's excellent piece from earlier in the year: http://blog.headius.com/2008/02/rubys-threadraise-threadkill-timeoutrb.html -----Original Message----- From: Shri Borde Sent: Monday, December 29, 2008 3:00 PM To: IronRuby External Code Reviewers Cc: ironruby-core@rubyforge.org Subject: Code Review: Thread#raise tfpt review "/shelveset:raise;REDMOND\sborde" Comment : Implements Thread#raise using Thread.Abort, and added tests for it Implemented stress mode (RubyOptions.UseThreadAbortForSyncRaise) which found more issues. Fixed most but not all Enabled test for timeout as well Remaining work (not high pri for now) - Thread#raise without Exception parameters is not supported as it needs to access the active exception of the target thread. This is stored as a thread-local static, and so cannot be accessed from other threads. Can be fixed by not using ThreadStaticAttribute. - Adding probes (in generated code, in C# library code, etc) will help to raise the exception quicker as Thread.Abort can be delayed indefinitely. Ideally, we need both approaches. For now, using Thread.Abort goes a long way. - Ideally, we would add a try-catch to the IDynamicObject/MetaObject code paths so that when other languages called into Ruby code, they would get the expected user exception rather than a ThreadAbortException RunRSpec: supports -ruby to run with MRI. Its much faster than doing "rake ruby why_regression". Added support for -e to run a specific example _______________________________________________ Ironruby-core mailing list Ironruby-core@rubyforge.org http://rubyforge.org/mailman/listinfo/ironruby-core
