* solvip/stdlib/gen_statem/export-start-types: Create a gen_statem type for enter_loop options gen_statem exports types related to starting & naming

2019-01-21correct: Work around a compiler mis-optimizationRaimo Niskanen
This was not a compiler optimization that misfired, rather that the code neede separate case clauses for when the timer was running and not, so to not call erlang:cancel_timer/1 nor maps:remove/2 in the case clause where only a map update was needed before recursion. See the comment in loop_timouts_cancel/13

2019-01-17Work around a compiler mis-optimizationRaimo Niskanen
The common subexpression optimization accidentally caused unnecessary spilling of live registers. A rather ugly workaround can be found in loop_timeouts_cancel.
2019-01-17Move out helper functions to engine loopRaimo Niskanen
This strategy improves speed benchmarks and reduces the amount of garbage that is produced. More: * Handle transition options as loop function arguments instead of in a record. * Shorten the state_enter loop and make it more efficient by making it more part of the loop and less a loop restart. * Simplify the internal timeout action handling somewhat.

2019-01-14Optimize gen_statem engine loopRaimo Niskanen
* Use synchronolus cancel_timer since that is more efficient than asynchronous when a process cancels its own timer * Restructure the state to have fewer fields by breaking out practically constant fields into a separate loop argument record #params{}, group state and data into one field and dito for timer fields * Optimize engine loop arguments for staying in the loop so the detour to sys:handle_system_message/6 will require packing/unpacking of the sys: state, and of the argument Parent * Avoid double reverse of event queue in many cases * Restructure the state transition to not have duplicate tracks for sys_debug and non-sys_debug cases * Shortcut the empty list case where possible * Loop unroll reversal of up to 2-element lists to avoid calling lists:reverse/2 since an external call spills all live registers to the stack * Bring out the callback mode check to the engine loop
2018-12-13gen_statem exports types related to starting & namingSölvi Páll Ásgeirsson
Currently, a user of gen_statem cannot use gen_statem types related to naming & starting in their behaviour implementations As an example, we cannot do: -spec start_link(Options) -> gen_statem:start_ret() when Options :: some_complex_thing(). start_link(Options) -> gen_statem:start_link(?MODULE, [Opts], []). As dialyzer, if configured to complain about unknown types, will warn that the type gen_statem:start_ret() is unknown. Likewise, for the same reason, we cannot do: -spec do_call_to_gen_statem(ServerRef) -> Reply when ServerRef :: gen_statem:server_ref(), Reply :: term(). do_call_to_gen_statem(ServerRef) -> gen_statem:call(ServerRef, do_thing). This fixes that by exporting the appropriate types

The postponed events, the user state and data, and the error reason are all limited in error events (if the Kernel variable error_logger_format_depth is set).

in case of active timers exists. Added unit tests for hibernate_after functionality combined with gen_statem timers.

It was done because "hibernate_after" option already used in ssl for the same reason.
