The port supports both smp and non-smp + emulator. For details around the port and how to started + see the User's Guide in the <seealso + marker="ose:ose_intro">ose</seealso> application. </p> + <p> + Note that not all parts of Erlang/OTP has been ported. </p> + <p> + Notable things that work are: non-smp and smp emulators, + OSE signal interaction, crypto, asn1, run_erl/to_erl, + tcp, epmd, distribution and most if not all non-os + specific functionality of Erlang.</p> + <p> + Notable things that does not work are: udp/sctp, os_mon, + erl_interface, binding of schedulers.</p> + <p> + Own Id: OTP-11334</p> + </item> + <item> + <p> + Add the {active,N} socket option for TCP, UDP, and SCTP, + where N is an integer in the range -32768..32767, to + allow a caller to specify the number of data messages to + be delivered to the controlling process. Once the + socket's delivered message count either reaches 0 or is + explicitly set to 0 with inet:setopts/2 or by including + {active,0} as an option when the socket is created, the + socket transitions to passive ({active, false}) mode and + the socket's controlling process receives a message to + inform it of the transition. TCP sockets receive + {tcp_passive,Socket}, UDP sockets receive + {udp_passive,Socket} and SCTP sockets receive + {sctp_passive,Socket}. </p> + <p> + The socket's delivered message counter defaults to 0, but + it can be set using {active,N} via any gen_tcp, gen_udp, + or gen_sctp function that takes socket options as + arguments, or via inet:setopts/2. New N values are added + to the socket's current counter value, and negative + numbers can be used to reduce the counter value. + Specifying a number that would cause the socket's counter + value to go above 32767 causes an einval error. If a + negative number is specified such that the counter value + would become negative, the socket's counter value is set + to 0 and the socket transitions to passive mode. If the + counter value is already 0 and inet:setopts(Socket, + [{active,0}]) is specified, the counter value remains at + 0 but the appropriate passive mode transition message is + generated for the socket.</p> + <p> + Thanks to Steve Vinoski</p> + <p> + Own Id: OTP-11368</p> + </item> + <item> + <p> + A call to either the <c>garbage_collect/1</c> BIF or the + <c>check_process_code/2</c> BIF may trigger garbage + collection of another processes than the process calling + the BIF. The previous implementations performed these + kinds of garbage collections without considering the + internal state of the process being garbage collected. In + order to be able to more easily and more efficiently + implement yielding native code, these types of garbage + collections have been rewritten. A garbage collection + like this is now triggered by an asynchronous request + signal, the actual garbage collection is performed by the + process being garbage collected itself, and finalized by + a reply signal to the process issuing the request. Using + this approach processes can disable garbage collection + and yield without having to set up the heap in a state + that can be garbage collected.</p> + <p> + The <seealso + marker="erts:erlang#garbage_collect/2"><c>garbage_collect/2</c></seealso>, + and <seealso + marker="erts:erlang#check_process_code/3"><c>check_process_code/3</c></seealso> + BIFs have been introduced.

A + call to <c>code:purge/1</c> and <c>code:soft_purge/1</c> + may complete faster or slower depending on the state of + the system while the system as a whole wont be as much + negatively effected by the operation as before.</p> + <p> + Own Id: OTP-11388 Aux Id: OTP-11535, OTP-11648 </p> + </item> + <item> + <p> + Add sync option to file:open/2.</p> + <p> + The sync option adds the POSIX O_SYNC flag to the open + system call on platforms that support the flag or its + equivalent, e.g., FILE_FLAG_WRITE_THROUGH on Windows.
