thread safety

Hello,

May I ask if ruby is thread safety for using the already thread-safe
libraries?

THANKS

Thread safety is not a property of a programming language and only to a
certain extend of library code. Ultimately it is a property of a particular
application that requires work to make it thread safe. You cannot just take
e.g. a synchronized version of a container and automatically obtain a
thread safe application.

Example: let us assume h is a Hash where all methods are synchronized on
the same lock. Then this code is not thread safe because h could be
modified between this thread executes the first and second line:

if h.has_key?(x) then
  puts h.fetch(x)
end

Cheers
