'Thread.main.exit!' and/or 'Kernel.exit!' does not work under certain
circumstances
------------------------------------------------------------------------------------
Key: JRUBY-1286
URL: http://jira.codehaus.org/browse/JRUBY-1286
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.0.0, JRuby 1.1.0
Environment: Linux
Reporter: Martin Krauskopf
I'm trying to solve problem why classic debugger in debug-commons does not exit
under Windows. It is caused by the fact that 'Kernel.exit!' does not exit the
underlaying process. As trying to reproduce with simple test-case I've got to
the following one under Linux which might be related to the Windows problem.
Not sure, the one under Windows might be different.
Following code exit under C Ruby but not under JRuby (running Linux). It might
cause by the 'next' call somehow (?).
{code}
terminator = Thread.new do
sleep 2
puts 'exit'
exit!
end
Kernel.module_eval(<<-"end;"
alias_method(:debug_commons_set_trace_func, :set_trace_func)
def set_trace_func(proc)
raise "Cannot call 'set_trace_func' method during debugging session."
end
end;
)
debug_commons_set_trace_func(lambda do |_, _, _, _, _, _|
next if Thread.current == terminator
loop do
puts Thread.current.object_id
sleep 1
end
end)
p "whatever...."
{code}
