There would be a need to execute J scripts or code asyncronously, which I'm unclear on any methods for curent approximation.
the isigraph events model would be fine. So would the socket handler... To just handle non blocking calls. A more ambitious plan would be a yield. control structure, and "yield_handler" classes. Yield handler classes would allow implementations from full blown coroutines to simple notify when complete accumulators. Also, Lazy data structures, Accumulators that report what they have so far (Useful for data management or web apps where large data sets can be returned, but you want to display the begining. Also useful for processes that operate on a large list, but can short circuit and terminate if the answer is found early on.) --- Oleg Kobchenko <[EMAIL PROTECTED]> wrote: > No nested transactions. > See more at > http://www.sqlite.org/lang_transaction.html > > But there is extensive handling of concurrency and > locks > http://www.sqlite.org/lockingv3.html > > There is also sqlite3_busy_timeout which I can be > added to > handle concurrency with resonable retry timeouts. > > > --- bill lam <[EMAIL PROTECTED]> wrote: > > > I tested and found database file is not > exclusively locked by a process in that > > two processes (J instances) can access the same > database file concurrently.
