asynchronous

Asynchronous Patterns for Ruby Based on Pure MRI CRuby code The goal is to use the original MRI C libs for achive real async patterns in ruby

Well it is achived...

OS managed thread

copy on write memory share, so you cant change anything in the mother process only with the return value later. This method is stronger the more CPU core the os have

Ideal for Big jobs that require lot of memory allocation or heavy CPU load to get a value Like parsing (in some case)

calculation = async :parallelism do

  sleep 4
  # remember, everything you
  # write here only mather in this block
  # will not affect the real process only
  # the last return value of the block
  4 * 5

end

# to call the value (syncronize):
calculation.value

VM managed thread

you can use simple :c also instead of :concurrency as sym, remember :concurrency is all about GIL case, so you can modify the objects in memory This is ideal for little operations in simultaneously or when you need to update objects in the memory and not the return value what is mather. Remember well that GarbageCollector will affect the speed.

calculation= async { sleep 3; 4 * 3 }
# to call the value (syncronize):
calculation.value

Examples

the "simple async processing" will let you use os threads (1.9.n+) for multiprocessing so you can give multiple task to do and until you ask for the value, the process will be in the background You can also use OS threads instead of VM Threads for real Parallelism

the "require_files" shows you how can you get files from directory in a recursive way and stuffs like that so you can be lay
