2015-02-26Ensure dbg tracer exits when dbg is stoppedJames Fish
Previously the tracer might receive an 'EXIT' message in the trace receive loop and treat it as garbage. Test uses a custom dbg process handler to reliably recreate the race condition, i.e. the message order {trace, ..}, {'EXIT, ..}.
2015-02-25Fix error matching in traffic suiteAnders Svensson
Clause matching error for specific test cases was harmless since the subsequent clause also matched. Errors detected by the server result in Failed-AVP being sent, which should not lead to a decode error in the client.
2015-02-25Don't discard outgoing answers with Result-Code/E-bit errorsAnders Svensson
Outgoing answers missing a Result-Code AVP or setting an E-bit inappropriately were discarded, but there's no particular reason for doing so if the answer can be encoded, and the sender has no way of knowing that their answer has been discarded. It's also inappropriate that the message be discarded in the relay case. Answers are now sent, and an error counter incremented.

2015-02-24Fix SCTP match blunder in suitesAnders Svensson
More than an incoming message can contain ancillary data, which the gen_sctp and transport suites did not expect. On FreeBSD 10, an sctp_assoc_change event appears always to contain ancillary data.

2015-02-20Be backwards compatible with diameter_sctp listener stateAnders Svensson
Commit 24993fc2 modified the state even in the case that the new pool_size option the change was introduced to support was not used. Doing so made downgrade impossible since old code would not be prepared for the modified state. Retain a compatible state, so that simple code replacement is enough.
2015-02-20Add gen_tcp testcase that fails sporadicallyAnders Svensson
On OS X at least. The testcase opens a listening socket, spawns 8 processes that call gen_tcp:accept/1, waits a couple of seconds, and then spawns 8 processes that call gen_tcp:connect/3. Some of these occasionally return {error, econnreset}.
2015-02-20Simplify transport suiteAnders Svensson
Using the fact that transport processes can now be started concurrently. The suite serialized starts itself when pretending to be diameter starting a transport process.
2015-02-20Remove (ancient) dead codeAnders Svensson
Commit 9a671bf0 removed the need for diameter_sctp to send outgoing messages through the listening process. That was prior to R5B02, so the clause isn't need for any upgrade case.

Which hasn't received any attention for some time. Clean it up, rename the poorly named peer.erl (it's Diameter *nodes* that are implemented), and make the it possible to specify arbitrary transport configuration.
2015-02-20Improve language consistency in diameter(1)Anders Svensson

2015-02-20Add pool suite to test transport_opt() pool_sizeAnders Svensson
With testcases that uses restrict_connections and pool_size config to establish multiple connections between two Diameter nodes, checking for the expected number of transport processes using diameter:service_info/2.
2015-02-20Adapt tcp/sctp transport modules for pool_size > 1Anders Svensson
In particular, that starts for the same transport reference can now be concurrent. Looking up a listener process and starting a new one if not found did handle this (more than one process could find no listener), and diameter_sctp assumed there could only be one transport process waiting for an association.
2015-02-20Add transport_opt() pool_sizeAnders Svensson
Transport processes are started by diameter one at a time. In the listening case, a transport process accepts a connection, tells the peer_fsm process, which tells its watchdog process, which tells its service process, which then starts a new watchdog, which starts a new peer_fsm, which starts a new transport process, which (finally) goes about accepting another connection. In other words, not particularly aggressive in accepting new connections. This behaviour doesn't do particularly well with a large number of concurrent connections: with TCP and 250 connecting peers we see connections being refused. This commit adds the possibilty of configuring a pool of accepting processes, by way of a new transport option, pool_size. Instead of diameter:add_transport/2 starting just a single process, it now starts the configured number, so that instead of a single process waiting for a connection there's now a pool. The option is even available for connecting processes, which provides an alternate to adding multiple transports when multiple connections to the same peer are required. In practice this also means configuring {restrict_connections, false}: this is not implicit. For backwards compatibility, the form of diameter:service_info(_,transport) differs in the connecting case, depending on whether or not pool_size is configured. Note that transport processes for the same transport_ref() can be started concurrently when pool_size > 1. This places additional requirements on diameter_{tcp,sctp}, that will be dealt with in a subsequent commit.

'dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation' into maint * dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation: mnesia: Check nodes after protocol negotiation OTP-12473
2015-02-10mnesia: Check nodes after protocol negotiationJean-Sébastien Pédron
During Mnesia startup, after protocol negotiation, the list of connected nodes is written to "recover_nodes". This list is later used to merge the schema. If Mnesia was stopped on a remote node between the protocol negotiation and the moment the list is stored in "recover_nodes", the remote node is still considered running: the value of "recover_nodes" stored during mnesia_down/1 is overwritten. Therefore, this node may be used to acquire a write lock on the schema in order to perform the merge. In this case, the remote node never answers to the lock request and Mnesia hang forever (application:start(mnesia) never returns). To fix the problem, we check the list one last time and remove from it all nodes where Mnesia is stopped. And because there is still a chance for missing mnesia_down event, handle_cast({mnesia_down, ...}, ...) writes to recover_nodes again, in addition to mnesia_down/1.
