Hello

How do to write a synchronized class like in java for Ruby

I try with a Mutex but if a method call another method of the same
instance I obtain a Deadlock.

Thanks
Guillaume

I wrote a reentrant mutex class at one point in time ...

Give it a shot and see if it fixes your deadlock issue.

Blessings,

Sorry, but you could have saved yourself the effort because it's part
of the standard library:

17:45:59 $ ruby19 -r monitor -e 'm=Monitor.new;m.synchronize {
m.synchronize { p 1 } }'
1
17:46:05 $ ruby19 -r thread -e 'm=Mutex.new;m.synchronize {
m.synchronize { p 1 } }'
<internal:prelude>:6:in `lock': deadlock; recursive locking (ThreadError)
        from <internal:prelude>:6:in `synchronize'
        from -e:1:in `block in <main>'
        from <internal:prelude>:8:in `synchronize'
        from -e:1:in `<main>'
17:46:17 $ ruby19 -r monitor -e 'm=Monitor.new;m.synchronize {
m.synchronize { p 1 } }'
1
17:46:23 $

Kind regards
