2017-08-15Replace calls to inet_parse(3)Anders Svensson
With the documented calls to inet(3).

2017-06-13Avoid recreating recordsAnders Svensson
This old construction is approximately two to four times slower from best (no elements modified) to worst (all modified) case, with the new construction having constant speed.
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.
2016-06-11Use rand(3) instead of random(3)Anders Svensson
The latter is deprecated in OTP 19.
2015-08-13Merge branch 'maint-17' into maintAnders Svensson
The diffs are all about adapting to the OTP 18 time interface. The code was previously backwards compatible, falling back on the erlang:now/0 if erlang:monotonic_time/0 is unavailable, but this was seen to be a bad thing in commit 9c0f2f2c. Use of erlang:now/0 is now removed.

* anders/diameter/17/time/OTP-12926: Simplify time manipulation Remove use of monotonic time in pre-18 code Remove unnecessary redefinition of erlang:max/2
2015-08-05Simplify time manipulationAnders Svensson
By doing away with more wrapping that the parent commit started to remove.
2015-08-05Remove use of monotonic time in pre-18 codeAnders Svensson
This has been seen to be a bottleneck at high load: each undef results in a loop out to the code server. Originally implemented as suggested in the erts user's guide, in commits e6d19a18 and d4386254.
2015-08-04Replace calls to module inet_parse to equivalents in inetAnders Svensson
Commits b563c796 (R16B) and 0fad6449 (R16B02) added parse_address/1 and ntoa/1 to module inet, providing documented alternatives to address/1 and ntoa/1 in the undocumented (save comments in inet(3)) inet_parse.

2015-03-20Disable deprecated warning on erlang:now/0 in diameter_libAnders Svensson
The code itself is backwards compatible with OTP 17, since development is still largely based on 17. Updates for the new time api in OTP 18 were merged into maint in commit 5e5b2221, and on to master in commit ebf24297. Conflicts: lib/diameter/src/base/diameter_lib.erl
2015-03-19Adapt to changes in time apiAnders Svensson
erlang:convert_time_resolution/3 has been renamed to convert_time_unit. erlang:time_resolution/0 has been removed: use new time resolution values instead.

2015-02-20Use new time api in implementationAnders Svensson
In particular, deal with the deprecation of erlang:now/0 in OTP 18. Be backwards compatible with older releases: the new api is only used when available. The test suites have not been modified.
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.
2015-01-19Monitor more efficiently at shutdownAnders Svensson
There's no need for building a pid list only to map it to a list of monitor references. Also, monitoring before banging the shutdown message makes for better trace, avoiding unnecessary noproc reasons when the process dies before the monitor is created.
2014-05-26Replace traffic-related log reports with no-op function callsAnders Svensson
The former were a little over-enthusiastic and could cause a node to be logged to death if a peer Diameter node was sufficiently ill-willed. The function calls are to diameter_lib:log/4, the arguments of which identify the happening in question, and which does nothing but provide a function to trace on. Many existing log calls have been shrunk. The only remaining traffic-related report (hopefully) is that resulting from {answer_errors, report} config, and this has been slimmed.
2013-03-25Minor diameter_lib cleanupAnders Svensson
Remove unused functions, add dialyzer specs, make wait/1 less fallible.
2011-10-17One makefile for src build instead of recursionAnders Svensson
Simpler, no duplication of similar makefiles and makes for better dependencies. (Aka, recursive make considered harmful.)
