2017-02-03Store messages for 'rex' and 'error_logger' off heapBjörn Gustavsson
Performance for processes that receive huge amounts of messages can be increased by storing the incoming messages outside the heap (that avoids copying the message in a garbage collection). Two OTP processes that are known to receive many messages are 'rex' (used by 'rpc') and 'error_logger'.

2016-05-02let the spawned processes handle rpc repliesZandra
This decreases the load on the rex server.

2016-04-07Update spec for rpc:pinfo/2Björn Gustavsson
rpc:pinfo/2 is documented as a location-transparent version of process_info/2. Therefore, it should be expected that the spec would allow calls with an item list, for example: rpc:pinfo(Pid, [initial_call,last_calls]) Report-URL: http://bugs.erlang.org/browse/ERL-124 Reported-by: bjfish

2016-03-11Don't throw exceptions from rpc:call() and rpc:block_call()Björn Gustavsson
The documentation for rpc:call() says: Evaluates apply(Module, Function, Args) on the node Node and returns the corresponding value Res, or {badrpc, Reason} if the call fails. What is not said that rpc:call() can generate an exception if the 'rex' process on the other node is killed: (kalle@host)1> Rex = rpc:call(arne@host, erlang, whereis, [rex]). <6937.14.0> (kalle@host)2> rpc:call(arne@host, erlang, exit, [Rex,kill]). ** exception exit: {killed, {gen_server,call, [{rex,arne@host}, {call,erlang,exit,[<6937.14.0>,kill],<0.33.0>}, infinity]}} in function rpc:rpc_check/1 (rpc.erl, line 361) On the other hand, if the other node shuts down for some other reason, we'll get a {badrpc,nodedown} result: (kalle@host)5> rpc:call(arne@host, erlang, halt, []). {badrpc,nodedown} There does not seem to be any reason to handle the two cases differently. If the 'rex' process is terminated on the other node, it will shut down shortly thereafter. Therefore, change rpc:call() and rpc:block_call() to always return {badrpc,Reason} is the call fails: (kalle@host)1> Rex = rpc:call(arne@host, erlang, whereis, [rex]). <6937.14.0> (kalle@host)2> rpc:call(arne@host, erlang, exit, [Rex,kill]). {badrpc,{'EXIT',{killed,{gen_server,call, [{rex,arne@host}, {call,erlang,exit,[<7126.14.0>,kill],<0.33.0>}, infinity]}}}}

2014-02-23Deprecate pre-defined built-in typesHans Bolinder
The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(), set(), and tid() have been deprecated. They will be removed in OTP 18.0. Instead the types array:array(), dict:dict(), digraph:graph(), gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid() can be used. (Note: it has always been necessary to use ets:tid().) It is allowed in OTP 17.0 to locally re-define the types array(), dict(), and so on. New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2, queue:queue/1, and sets:set/1 have been added.
