2013-02-16Add application_opt() request_errorsAnders Svensson
Configuring the value 'callback' all errors detected in incoming requests to result in a handle_request callback. The default value 'answer_3xxx' is the previous behaviour in which diameter answers protocol errors without a callback.

2013-02-11Fix test/depend.mk blunderAnders Svensson
Beam path in dependency was wrong.
2013-02-11Add transport_opt() length_errorsAnders Svensson
The value determines whether or not an unexpected message length in the header of an incoming messages causes the peer process to exit, the message to be discarded or handled as usual. The latter may only be appropriate for message-oriented transport (eg. SCTP) since stream-oriented transport (eg. TCP) may not be able to recover the message boundary once a length error has occurred.

2013-02-09Fix unsafe optimization of funsBjörn Gustavsson
Commits 53bd4974a101 and 726f6e4c7afe simplified the handling of match_fail (used to generated exceptions such as 'function_clause') by first rewriting them to a call to erlang/error{1,2} and later rewriting them to specialized BEAM instructions (to reduce the code size). There was one flaw, though, which only was exposed when more aggressive optimizations were added in c3b60f86c622. Here is an example to explain it: t(V) -> fun(get) -> V end. The following BEAM code will be initially generated for the fun: {function, '-t/1-fun-0-', 2, 5}. {label,1}. {line,[{location,"t.erl",5}]}. {func_info,{atom,t},{atom,'-t/1-fun-0-'},2}. {label,2}. {test,is_eq_exact,{f,2},[{x,0},{atom,get}]}. {move,{x,1},{x,0}}. return. {label,2}. {test_heap,2,1}. {put_list,{x,0},nil,{x,1}}. {move,{atom,function_clause},{x,0}}. {line,[{location,"t.erl",5}]}. {call_ext_only,2,{extfunc,erlang,error,2}}. Translating back to Erlang code, that would be roughly: '-t/1-fun-0-'(get, V) -> V; '-t/1-fun-0-'(Arg1, _) -> erlang:error(function_clause, [Arg1]). Note that the second argument (the free variable V) is not included in the call to erlang:error/2. The beam_except pass will simplify the code to: {function, '-t/1-fun-0-', 2, 8}. {label,1}. {line,[{location,"t.erl",5}]}. {func_info,{atom,t},{atom,'-t/1-fun-0-'},2}. {label,2}. {test,is_eq_exact,{f,1},[{x,0},{atom,get}]}. {move,{x,1},{x,0}}. return. The code has been shortened by jumping to the func_info/3 instruction. Translating back to Erlang: '-t/1-fun-0-'(get, V) -> V; '-t/1-fun-0-'(Arg1, Arg2) -> erlang:error(function_clause, [Arg1,Arg2]). it is clear that both arguments are now included in the 'function_clause' exception, even though the initially generated code only included the first argument. That is no problem in this particular case, but for some more complex funs, optimizing the first version based on variable usage could make the second version unsafe. I rejected the following potential solutions: - Including the free arguments in the call to erlang:error/2: '-t/1-fun-0-'(get, V) -> V; '-t/1-fun-0-'(Arg1, Arg2) -> erlang:error(function_clause, [Arg1,Arg2]). Unfortunately, that is tricky. The free variables are only known after the second pass in v3_kernel when variable usage has been calculated. We would need to add a third pass (only for funs) that would the free arguments to the second argument for erlang:error/2 *and* update the variable usage information. - Calling beam_except earlier, from within beam_block before any optimizations based on variable usages are done. But means that the problem could reappear in some other form in the future when other updates are done to the code generator and/or optimization passes. The solution I have chosen is to modify beam_except to only replace a call to erlang:error(function_class, Args) if the length of Args is the same as the arity in the func_info/3 instruction. The code will be slightly larger. Also, the free variables for funs and list comprehensions will no longer be included in the function_clause exception (that could be less confusing, but it also means less information during debugging).

2013-02-08Tweak service interface towards diameter_peerAnders Svensson
2013-02-08Split message handling in diameter_service into diameter_trafficAnders Svensson
Traffic handling is connected to the service implementation through the pick_peer callback and failover but diameter_service was getting unwieldy as home to both the service process and traffic handling.
2013-02-08Simplify request recordAnders Svensson
In particular, remove fields containing values that are known (as of the preceding commit) to the request process.
2013-02-08Move failover out of service processAnders Svensson
In order to be able to remove fields from the request process that don't need to be there and do less in the service process. The pick_peer callback now takes place in the request process in the case of immutable state, just as in the case of the initial send.

As an inverse to '#get-'/1 in the preceding commit.
2013-02-08Add exprecs '#get-'/1 for transforming records into listsAnders Svensson
The generated '#get-'/1 has one clause for each exported record r, whose definition is equivalent to the following. '#get-'(#r{} = Rec) -> [r | lists:zip(record_info(r, fields), tl(tuple_to_list(Rec)))]; The record name at the head of the list is the same format that diameter accepts for outgoing message.
2013-02-08Document the existence of the RFC 6733 dictionariesAnders Svensson
2013-02-08Don't hardcode common dictionaryAnders Svensson
Instead, use whatever dictionary a transport has configured as supporting application id 0. This is to support the updated RFC 6733 dictionaries (which bring with them updated records) and also to be able to transparently support any changed semantics (eg. 5xxx in answer-message).
2013-02-08Add RFC 6733 dictionariesAnders Svensson
The RFC 6733 accounting dictionary includes rfc6733 in its name. The RFC 3588 dictionary doesn't and is left as-is for backwards compatibility.
2013-02-08Fix testcases in event suiteAnders Svensson
The transition INITIAL -> DOWN (fixed in the preceding commit) was wrong.
2013-02-08Fix faulty watchdog transition INITIAL -> DOWNAnders Svensson
There is no such transition in RFC 3539, the state remains in INITIAL.

2013-02-08Fix faulty watchdog transition DOWN -> INITIALAnders Svensson
This was the result of the watchdog process exiting as a consequence of peer death in some casesi, causing a restarted transport to enter INITIAL when it should enter REOPEN. The watchdog now remains alive as long as peer shutdown isn't requested and a 'close' message to the service process (instead of watchdog death) generates 'closed' events from the service.
