I had to seek help, and so I showed it to my senior colleague Nicolas, I had then devised a test which would reproduce this neatly. He cut it down a bit, and I boiled it to the broth you see here and can compile and run for yourself. 在erlang进程里加了 process_flag(trap_exit, true). 这个进程报错监控进程直接重起没收到错误信息我现在用的不是otp里的是自己写的进程解答： --你貌似搞错了trap_exit的地方了。不是要死的process自我trap_exit, 而是他的监护process去trap_exit被监护的。 However, to avoid building the same exit message again and again for each peer process, it is build once in doit_exit_link() and passed to send_exit_signal() in the exit_tuple argument. When send_exit_signal() is invoked with a valid Erlang term in exit_tuple, it will invoke send_exit_message() instead of erts_deliver_exit_message() which will use the exit_tuple as is as the exit message. Erlang instead lets you specify that some processes are special and can be flagged with a trap_exit option. They can then take the exit signals sent over links and transform them into messages.

12.4 Process Termination. When a process terminates, it always terminates with an exit reason. The reason can be any term.

rdtsc on Mar 28, 2016 [-] It works correctly either way -- externally with exit (Pid,kill) or by the process itself as exit (kill). The last one is just a shorthand for exit (self (), kill). For exceptions of class exit, that is, the code called exit(Term), {'EXIT',Term} is returned. For exceptions of class throw , that is the code called throw(Term) , Term is returned. Reason depends on the type of error that occurred, and Stack is the stack of recent function calls, see Exit Reasons .

Se hela listan på medium.com A process which executes exit(Reason) where Reason is any Erlang term except the atom normal, also has an abnormal exit. An Erlang process can set up links to other Erlang processes. If a process calls link(Other_Pid) it sets up a bidirectional link between itself and the process called Other_Pid . Exists − There are two kinds of exits: 'internal' exits and 'external' exits. The internal exits are triggered by calling the function exit/1 and make the current process stop its execution. The external exits are called with exit/2 and have to do with multiple processes in the concurrent aspect of Erlang.
