Listening transports weren't removed, which diameter_reg:subs/0 revealed.
|
|
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.

|
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.

Letters are cheap.
|
|
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.

Unused, and in the way for what's to come.

Unexpected messages don't happen in practice, and no_auto_import is
neither necessery nor difficult to avoid.

Make it so that it is only possible to remove a tracer via

place in order to avoid a lot of lock checking and taking

happening on dirty schedulers.

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>
