Deadly Embrace, is it a problem?
I am seeking information on the possibility of a deadly-embrace situation occuring with SET REPORTESS TO -1.
For example, user 1 locks files A then B. User 2 attempts to lock B then A at the same instant. The first lock executed by each user succeeds and flock() returns. When trying to lock the second file, the lock does not succeed because A and B are both locked.
Is this a problem with VFP? If not, why not? Does the lock manager on the server account for this possibility, or is it just a very high statistical improbability? If it is a problem, what are some solutuions?
Thanks, Dennis Hevener
