Hi guys, I’ve just noticed that something happened to Thread.priority… It disappeared. I’m talking about Thread’s instance attribute - priority. I’m using the latest code from GitHub. The only available priority in the Thread instance now is a CamelCase priority, which is .Net’s Priority attribute… Take a look at the next REPL session: =\> #\ > > > t = Thread.new { puts “Start”; sleep(30); puts “end” } > > > tart=\> > > > #\ > > > > t.priority > > > :0: undefined method `priority’ for #\ > > > (NoMethodError) > > > t.Priority > > > =\> Normal I remember the priority attribute was problematic because it didn’t receive numeric values like MRI. Maybe this is related to that? Thanks, Shay. – ---

Ruby Thread#priority is not implemented yet. We disabled name mangling on built-ins recently so Thread.Priority property is not callable via lower-case name anymore. Tomas ---

Is it going to be implemented for V1? If yes, is it going to work as MRI with numeric values? Thanks! Shay. On 10/25/09, Tomas M.

Hello, I have done a very basic implementation of a while back but I did not finish the modifications to the specs to test this. Here are the commits if you want to grab it > de7f305 > 164f202 It was decided at some point that there would only be 5 valid values -2, -1, 0, 1 and 2 … mapping to the CLR thread priorities Lowest, BelowNormal, Normal, AboveNormal and Highest If anything lower than -2 is passed in the thread will be assigned Lowest and Highest if above 2.

Quick +1 to vote this patch up. I’ve been working on the JRuby support for the DataMapper ORM and DataObjects(.rb) database connectivity layer. These projects rely in turn on another project called Extlib, which provides a bunch of useful extensions (lazy arrays, thread pools, string extensions) for the other two projects. I pulled down and built the latest IronRuby and running Extlib’s specs, the lack of Thread#priority appears to be the first blocker in our support for IR.

What’s the status of the DataMapper port? I was just trying to use it but couldn’t get the gem installed. I’m interested in helping get this working. What next steps are needed? Thanks, Ryan R.

I remembered something like that. Thanks for pointing it out Pascal. Is it going to be incorporated into V1 code? Thanks! Shay. On Mon, Oct 26, 2009 at 1:49 AM, Pascal Normandin \< ---

I’m working on installing datamapper from the sources. However, I have to manually execute `ir -S gem install .\pkg\_.gem` each time after the gem is created.
