2016-06-11Remove unnecessary no_auto_importAnders Svensson
Not difficult to avoid, and better without.
2016-06-11Redo transport config server as a gen_serverAnders Svensson
To properly handle system messages. Initially implemented in commit 5ca5fb71.
2016-05-30Fix leaking transports in traffic/relay suitesAnders Svensson
Listening transports weren't removed, which diameter_reg:subs/0 revealed.
2016-05-30Close listening sockets at transport removalAnders Svensson
The transport interface documented in diameter_transport(3) is used to start/stop accepting/connecting transport processes: they're started with a function call, and told to die with their parent process. In the accepting case, both diameter_tcp and diameter_sctp start a listening process when the first accepting transport is started. However, there's no way for a listening process to find out that that it should stop listening when transport configuration is removed. Both diameter_tcp and diameter_sctp have used a timer to terminate the listening process after all existing accepting processes have died as a consequence of transport removal. The problem with this is that nothing stops a new client from connecting before this, and also that no new transport can succeed in opening the same listening port (eg. reconfiguration) until the old listener dies. This commit solves the problem by adding diameter_reg:subscribe/2, to allow callers to subscribe to messages about added/removed associations. A call to diameter:add_transport/2 results in a new child process that registers a term that a listening process subscribes to. Transport removal results in the death of the child, and the resulting notification to the listener causes the latter to close its socket and terminate. This is still an internal interface, but the subscription mechanism should probably be made external (eg. a diameter:subscribe/1 that can be used to subscribe to specified messages), so that transport modules other than diameter's own can make use of it. There is no support for soft upgrade.
2016-05-30Don't restart transport processes after transport removalAnders Svensson
A replacement accepting transport could be started after the service process received a shutdown message from diameter_config, if a connection was accepted before the transport process in question was terminated. The replacement lived on until the service needed to restart it.
2016-05-30Rename diameter_reg:del -> removeAnders Svensson
Letters are cheap.
2016-05-30Add diameter_reg:subscribe/2Anders Svensson
To allow processes to subscribe to a message when a matching association is added or removed. The intention is to use this in diameter_{tcp,sctp}, in order for listening processes to find out when transport their transport configuration has been removed.
2016-05-30Add dialyzer specs to diameter_regAnders Svensson
Last missed in commit 25bef13f.
2016-05-30Remove diameter_reg:repl/2Anders Svensson
Unused, and in the way for what's to come.
2016-05-30Remove diameter_reg bloatAnders Svensson
Unexpected messages don't happen in practice, and no_auto_import is neither necessery nor difficult to avoid.

Turns out we can not count on the "hashsigns" sent by the client and the supported "hashigns" sets to have required properties of ordsets.

2016-05-10erts: Implement max_heap_size process flagLukas Larsson
The max_heap_size process flag can be used to limit the growth of a process heap by killing it before it becomes too large to handle. It is possible to set the maximum using the `erl +hmax` option, `system_flag(max_heap_size, ...)`, `spawn_opt(Fun, [{max_heap_size, ...}])` and `process_flag(max_heap_size, ...)`. It is possible to configure the behaviour of the process when the maximum heap size is reached. The process may be sent an untrappable exit signal with reason kill and/or send an error_logger message with details on the process state. A new trace event called gc_max_heap_size is also triggered for the garbage_collection trace flag when the heap grows larger than the configured size. If kill and error_logger are disabled, it is still possible to see that the maximum has been reached by doing garbage collection tracing on the process. The heap size is defined as the sum of the heap memory that the process is currently using. This includes all generational heaps, the stack, any messages that are considered to be part of the heap and any extra memory the garbage collector may need during collection. In the current implementation this means that when a process is set using on_heap message queue data mode, the messages that are in the internal message queue are counted towards this value. For off_heap, only matched messages count towards the size of the heap. For mixed, it depends on race conditions within the VM whether a message is part of the heap or not. Below is an example run of the new behaviour: Eshell V8.0 (abort with ^G) 1> f(P),P = spawn_opt(fun() -> receive ok -> ok end end, [{max_heap_size, 512}]). <0.60.0> 2> erlang:trace(P, true, [garbage_collection, procs]). 1 3> [P ! lists:duplicate(M,M) || M <- lists:seq(1,15)],ok. ok 4> =ERROR REPORT==== 26-Apr-2016::16:25:10 === Process: <0.60.0> Context: maximum heap size reached Max heap size: 512 Total heap size: 723 Kill: true Error Logger: true GC Info: [{old_heap_block_size,0}, {heap_block_size,609}, {mbuf_size,145}, {recent_size,0}, {stack_size,9}, {old_heap_size,0}, {heap_size,211}, {bin_vheap_size,0}, {bin_vheap_block_size,46422}, {bin_old_vheap_size,0}, {bin_old_vheap_block_size,46422}] flush().

2016-05-09mnesia_ext: Create table/data containers from mnesia monitor not temporary ↵Dan Gudmundsson
processes Tables or data containers should be owned and monitored by mnesia_monitor and should thus be created by that process. Always create_table before loading it We need to create tables for ram_copies at least before loading them as they are intermittent. It is also needed to get mnesia monitor as the parent and supervisor of the data storage.
