I have a number of short-lived processes that are started out of some "worker" gen_server, which in turn is started and managed by a supervisor. An error in one of the short-lived processes is an error that should either be returned to the client of the gen_server, or just swallowed (perhaps with some recording of the fact that this happened).
Now, what is the "proper" way to do this within the OTP framework? Do I just call erlang:spawn()? The process will call me back using gen_server:call(). |

If you would like to build your system obeying the standard OTP principles, you might consider using proc_lib:spawn(_link)
Moreover, if those children lifetime is short term only and errors in those can be logged and then discarded, set trap_exit flag in the gen_server that spawns the processes, use spawn_link function and handle the exit signals in your handle_info/2 clause. |

| Using trap_exit and proclib:spawn_link sounds good. Thanks for the suggestion! |

| Popular nfl jerseys cheap are going to be scarce over the next three months.Then they're going to be more expensive.The most popular teams will experience the worst shortages, and the James Jones Jersey are breaking all sorts of popularity records this year, from on-field performance to stock sales to merchandise sales.To lure the customer towards their service, providers are leaving no stone unturned in order to provide several plans to make Josh Sitton Jersey.Thats why your website's critics are so vital, and ofcourse why companies must be alerted at all times.With the sport's new passing-crazed style of play challenging the traditional notion that Buffalo Sabres jerseys is a fundamental ingredient for postseason success, these Nick Collins Jersey will provide an intriguing look at the way to win in the NFL when the stakes are highest. |
