2015-10-26erts: Add {line_delimiter, byte()} option to inet:setopts/2Serge Aleynikov
A new {line_delimiter, byte()} option allows line-oriented TCP-based protocols to use a custom line delimiting character. It is to be used in conjunction with {packet, line}. This option also works with erlang:decode_packet/3 when its first argument is 'line'.

2015-07-11Teach Dialyzer arity of funs with literal arityLuca Favatella
Re-insert logic for `erlang:make_fun/3` in `erl_bif_types`. It had been removed in bd941f5 while type spec-ing `erlang.erl`. Type spec in `erlang.erl` cannot express arity of returned fun based on value of argument hence re-introducing logic in `erl_bif_types`. Re-definition of logic in `erl_bif_types` follows approach in 9d870a0.

2015-06-09Fix socket option {linger, {true, 0}} to abort TCP connectionsRory Byrne
Up until now, if {linger, {true, 0}} is set on the socket and there is data in the port driver queue, the connection is not aborted until the port queue is empty and close() is called on the underlying file descriptor. This bug allows an idle TCP client to prevent a server from terminating the connection and freeing resources. This patch fixes the problem by discarding the port queue if the socket is closed when {linger, {true, 0}} is set.
2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

2015-05-12Fix gen_tcp:shutdown/2 by making it asynchronousRory Byrne
If the driver queue is empty, or the user is requesting a 'read' shutdown, then the shutdown() syscall is performed synchronously, as per the old version of shutdown/2. However, if the user is requesting a 'write' or 'read_write' shutdown, and there is data in the driver queue for the socket, then the shutdown() syscall is delayed and handled asynchronously when the driver queue is written out. This version of shutdown solves a number of issues with the old version. The two main solutions it offers are: * It doesn't block when the TCP peer is idle or slow. This is the expected behaviour when shutdown() is called: the caller needs to be able to continue reading from the socket, not be prevented from doing so. * It doesn't truncate the output. The current version of gen_tcp:shutdown/2 will truncate any outbound data in the driver queue after about 10 seconds if the TCP peer is idle of slow. Worse yet, it doesn't even inform anyone that the data has been truncated: 'ok' is returned to the caller; and a FIN rather than an RST is sent to the TCP peer. For a detailed description of all the problems with the old version of shutdown, please see the EEP Light that was written to justify this patch.

2015-03-20Erlang based BIF timer implementation for scalabilityRickard Green
2015-03-20Introduce a new time APIRickard Green
The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.
