In the OpenLDAP, the incoming requests are first inserted in a list and then
assigned to the work threads.
Take a scenario as follow, there are T1,T2,T3,...Tn requests in order, T1 2
is a "modify request", and T3 is
a "search request".If these request are serially handled one by one, then T3
will get the updated info by T2.
But if the requests are assigned to work threads and handled
concurrently, will the following case happen?
T2 and T3 are assigned to Thread A and Thread B, but Thread B is scheduled
before A. So T2 is handled
after T3. And later request, T3 will never get the newly updated info?
If this case can never happend, how does OpenLDAP guarantee the incoming
requests are handled in order
even if the work threads are scheduled randomly?
Thanks a lot:)
