* anders/diameter/performance/OTP-13164: Make peer handling more efficient Remove unnecessary erlang:monitor/2 qualification
2015-12-21Make peer handling more efficientAnders Svensson
Each service process maintains a dictionary of peers, mapping an application alias to a {pid(), #diameter_caps{}} list of connected peers. These lists are potentially large, peers were appended to the end of the list for no particular reason, and these long lists were constructed/deconstructed when filtering them for pick_peer callbacks. Many simultaneous outgoing request could then slow the VM to a crawl, with many scheduled processes mired in list manipulation. The pseudo-dicts are now replaced by plain ets tables. The reason for them was (once upon a time) to have an interface interchangeable with a plain dict for debugging purposes, but strict swapablity hasn't been the case for some time now, and in practice a swap has never taken place. Additional tables mapping Origin-Host/Realm have also been introduced, to minimize the size of the peers lists when peers are filtered on host/realm. For example, a filter like {any, [{all, [realm, host]}, realm]} is probably a very common case: preferring a Destination-Realm/Host match before falling back on Destination-Realm alone. This is now more efficiently (but not equivalently) expressed as {first, [{all, [realm, host]}, realm]} to stop the search when the best match is made, and extracts peers from host/realm tables instead of searching through the list of all peers supporting the application in question. The code to try and start with a lookup isn't exhaustive, and the 'any' filter is still as inefficient as previously.

By not failing in code that looks up state: pick_peer and service_info.
2015-12-09Fix request table leak at retransmissionAnders Svensson
In the case of retranmission, a prepare_retransmit callback could modify End-to-End and/or Hop-by-Hop identifiers so that the resulting diameter_request entry was not removed, since the removal was of entries with the identifiers of the original request. The chances someone doing this in practice are probably minimal.
2015-12-09Fix request table leak at exit signalAnders Svensson
The storing of request records in the ets table diameter_request was wrapped in a try/after so that the latter would unconditionally remove written entries. The problem is that it didn't deal with the process exiting as a result of an exit signal, since this doesn't raise in an exception. Since the process in question applies callbacks to user code, we can potentially be linked to other process and exit as a result. Trapping exits changes the current behaviour of the process, so spawn a monitoring process that cleans up upon reception of 'DOWN'.

2015-09-01erts: Fix bug when tracing with 'process_dump'Sverker Eriksson
If the process stack contained a match state the print function would crash the vm as it was not recognized by tag_val_def(). Add new MATCHSTATE_DEF returned by tag_val_def(). All other callers either ignore it or has a default clause to handle invalid terms.
2015-08-25Add service_opt() strict_mbitAnders Svensson
There are differing opinions on whether or not reception of an arbitrary AVP setting the M-bit is an error. 1.3.4 of RFC 6733 says this about how an existing Diameter application may be modified: o The M-bit allows the sender to indicate to the receiver whether or not understanding the semantics of an AVP and its content is mandatory. If the M-bit is set by the sender and the receiver does not understand the AVP or the values carried within that AVP, then a failure is generated (see Section 7). It is the decision of the protocol designer when to develop a new Diameter application rather than extending Diameter in other ways. However, a new Diameter application MUST be created when one or more of the following criteria are met: M-bit Setting An AVP with the M-bit in the MUST column of the AVP flag table is added to an existing Command/Application. An AVP with the M-bit in the MAY column of the AVP flag table is added to an existing Command/Application. The point here is presumably interoperability: that the command grammar should specify explicitly what mandatory AVPs much be understood, and that anything more is an error. On the other hand, 3.2 says thus about command grammars: avp-name = avp-spec / "AVP" ; The string "AVP" stands for *any* arbitrary AVP ; Name, not otherwise listed in that Command Code ; definition. The inclusion of this string ; is recommended for all CCFs to allow for ; extensibility. This renders 1.3.4 pointless unless "*any* AVP" is qualified by "not setting the M-bit", since the sender can effectively violate 1.3.4 without this necessitating an error at the receiver. If clients add arbitrary AVPs setting the M-bit then request handling becomes more implementation-dependent. The current interpretation in diameter is strict: if a command grammar doesn't explicitly allow an AVP setting the M-bit then reception of such an AVP is regarded as an error. The strict_mbit option now allows this behaviour to be changed, false turning all responsibility for the M-bit over to the user.
