Re: just a curiosity - pre emptive threads

I agree it would be nice to eventually have preemptive mode on the client side, but I also think the subject needs to be discussed in context. Preemptive mode makes it possible to run multiple processes independent of each other concurrently, so the primary benefactor should be the server.

Of course, SAVE RECORD, DELETE RECORD is needed to invoke trigger. However, the method that call SAVE RECORD would be executed in 4D Remote and 4D Remote isn't supported. A dead lock? Alan Chan 4D iNug Technical <4d_tech@lists.4d.com> writes: >there is no "thread safe" property for triggers. >

Re: just a curiosity - pre emptive threads

there is no "thread safe" property for triggers. however, if you use commands like SAVE RECORD, DELETE RECORD from a method chain that is marked as thread safe, then the call chain of that table's trigger is checked for thread safety at compile time. in fact the compiler is smart enough to

So.. I have this component Setutl. which does a bunch of handy things that 4D's native set operations do not do, for example being able to ask, and get an answer to: - Which table does this set belong to - What set(s) exist for a specified table As the component stands it is thread safe (I

IP vars are out. -- OK IP sets would be out too, but... How does 4D manage IP sets, that it does not know are IP sets? I know in more then one place I don't care about a set name, and use an algorithm to create a set name. So the set name does not exist until execution. This kind of code could
