some frameworks opinionated when comes database locking. example, grails orm (gorm) documents state following: by default gorm classes configured optimistic locking source : https://grails.github.io/grails-doc/latest/guide/gorm.html#locking i've read through material online rails , understanding rails not provide locking default. what rails default approach locking? note : not question approach best, question confirm rails's approach locking. by default, i'm pretty sure database locking turned off in rails. if want use locking, have @ ruby on rails docs: http://api.rubyonrails.org/classes/activerecord/locking/pessimistic.html

what going on in program here? why myfunction print 3 x? int myfunction(int); void main(void) /* local variables: x, result in main */ { int result, x = 2; result = myfunction(x); printf("%i", result); /* prints "3" */ printf("%i", x); /* prints "2" */ } int myfunction (int x) { x = x + 1; printf("%i\n", x); /* prints "3" */ return x; } that's because parameter local variable in function. when function called, there space allocated on stack parameter, , value variable x copied parameter. in function parameter x local varible, separate variable x in calling code. when x increased in function, happens local copy. when function ends, parameter goes away when stack frame function removed stack.
