2017-07-12erts: Fix bug in bxor of a big negative numberSverker Eriksson
Wrong result for (X bsl WS) bxor Y. where X is any negative integer Y is any integer that does not require more words than X WS is erlang:system_info(wordsize) or larger Fix: The subtraction of 1 (for 2-complement conversion) must be carried along all the way to the last words.

Whether making record declarations unreadable to compensate for dialyzer's ignorance of match specs is worth it is truly debatable.

OTP-13342 remote watchdog transition to state SUSPECT
2016-02-19Fix handling of shared peer connections in watchdog state SUSPECTAnders Svensson
A peer connection shared from a remote node was regarded as being available for peer selection (aka up) as long as its peer_fsm process was alive; that is, for the lifetime of the peer connection. In particular, it didn't take note of transitions into watchdog state SUSPECT, when the connection remains. As a result, retransmissions could select the same peer connection whose watchdog transition caused the retransmission. A service process now broadcasts a peer_down event just as it does a peer_up event. The fault predates the table rearrangements of commit 8fd4e5f4.
2016-02-19Remove unnecessary parenthesesAnders Svensson
Not needed as of commit 6c9cbd96.
2016-02-19Remove dead exportAnders Svensson
The export of diameter_traffic:failover/1 happened with the creation of the module in commit e49e7acc, but was never needed since the calling code was also moved into diameter_traffic.
2016-02-09ssl: fix hibernate_after with short timeoutsAndrey Mayorov
Too wide function clause was used in ssl_connection which led to ssl connection process crashes when `{hibernate_after, N}` with extremely small N was passed among other options to `ssl:connect`.

* 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.

2015-12-20Be resilient to diameter_service state upgradesAnders Svensson
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'.
