2017-03-08Add transport_opt() capx_strictnessAnders Svensson
To allow the Peer State Machine requirement that only the expected capabilities exchange message be received in the relevant state to be relaxed. If {capx_strictness, false} is configured then anything bu the expected CER/CEA is ignored. This is non-standard behaviour, and thusfar undocumented. Use at your own risk.
2017-03-07Avoid sending large terms between nodes unnecessarilyAnders Svensson
When relaying outgoing requests through transport on a remote node, terms that were stripped when sending to the transport process weren't stripped when spawning a process on the remote node. Also, don't save the request to the process dictionary in a process that just relays an answer.
2017-03-07Don't use request table for answer routingAnders Svensson
The table has existed forever, to route incoming answers to a waiting request process: each outgoing request writes to the table, and each incoming answer reads. This has been seen to suffer from lock contention at high load however, so this commit moves the routing into the diameter_peer_fsm processes that are diameter's conduit to transport processes. The request table is still used for failover detection, but entries are only written when a watchdog state transitions leaves or enters state OKAY.

OTP-14206 fix 19.1 failover blunder, use diameter_request less
2017-02-24Fix/redo failover optimizationAnders Svensson
Commit 9a878743 addressed inefficiency at failover, but introduced inefficiency in the sending of outgoing requests in so doing: each outgoing request added an request table entry keyed on a transport pid, then looked for a specific element with this key, and then (later) removed the inserted element. Since the request table is a bag, this results in linear searches over a potentially long list of element keyed on the same pid. The higher the rate of outgoing calls, the more costly it becomes. Instead of writing entries to the request table, the peer_up/down calls to diameter_traffic that mirror transitions to and from the OKAY state in the RFC 3539 watchdog state machine now result in a process for request processes to monitor in order to detect failover.

2016-09-11Let unfortunate min_heap_size setting be disabledAnders Svensson
The setting in all diameter server processes has existed since the beginning of time. Whether it's actually useful is questionable, but it does lead to increased memory usage, especially if there are many peer connections whose processes wouldn't otherwise be large. Let the setting be disabled with -diameter min_heap_size false. (Or any value that isn't a non-negative integer.) The diameter application itself only calls diameter_lib:spawn_opts(server, []), but let other arguments remain for backwards compatibility, since diameter_lib:spawn_opts/2 has been abused from outside of diameter.

The SCPT stack has a different behavior in solaris2.10 then in later versions and linux. Diameter implementation does not support this behavior.

"Defaults to X" isn't clarified by "if unspecified".
2016-08-26Don't run traffic tests in parallel when {string_decode, true}Anders Svensson
Since the large strings copied between processes cause testcases to fail randomly. Option string_decode was added in commit 1590920c.
2016-08-26Close listening sockets at service deathAnders Svensson
Commit 5ca5fb71 ensured that they were closed immediately at transport removal, but in so doing broke their closing at stop service completely, by removing the timer that caused sockets to be closed even belatedly. Monitor on the service process to make it happen. This could still be improved, since stop_service listening ports aren't closed until after the service process has died. They could be closed earlier in the case of stop_service.

The copyright was a historical remnant of diameter's roots prior to its inclusion in OTP. Thanks to Anatolie Golovco.

One more followup to https://github.com/erlang/otp/pull/1056 and https://github.com/erlang/otp/pull/1023 This time it's about `/usr/bin/env` and `/bin/cp`: - `/usr/bin/env` in `diameterc` was used to find the bootstrapped `escript` executable. Changed it to exlpicit call to `escript` in Makefile. - `/usr/bin/env` and `/bin/cp` were referenced in documentation build/install process. Now full paths to this tools are injected using autoconf magic.

That missed comm_up when something like the following was received on FreeBSD (for one): {sctp,#Port<0.599>, {127,0,0,1}, 45455, {[{sctp_sndrcvinfo,0,0,[],0,0,0,0,145060462,3}], {sctp_assoc_change,comm_up,0,10,10,3}}}

The latter is deprecated in OTP 19.

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.
