Feature #5371: add marshalling support for Mutex

• Status: Rejected
• Assignee: -
• Target version: 2.0.0

Hello,

Please add marshalling support for the Mutex class:

$ irb

Marshal.dump(Mutex.new)
TypeError: no marshal_dump is defined for class Mutex
from (irb):1:in dump' from (irb):1 from /usr/bin/irb:12:in '

Here is the workaround I am currently using:

class Mutex
def marshal_dump
[]
end
def marshal_load array
# do nothing
end
end

Thanks for your consideration.

Hello,

Please add marshalling support for the Mutex class:

$ irb

Marshal.dump(Mutex.new)
TypeError: no marshal_dump is defined for class Mutex
       from (irb):1:in dump'        from (irb):1        from /usr/bin/irb:12:in '

Because of, Almost all OSs don't have a way to restore mutex locking state.
I have no idea how implement it. ;-)

Here is the workaround I am currently using:

class Mutex
 def marshal_dump
   []
 end
 def marshal_load array
   # do nothing
 end
end

Thanks for your consideration.

Hmmm??
It seems locking state lost. Is this acceptable?
