2017-05-02"auto_hibernate_timeout" option renamed to "hibernate_after".Anton N Ryabkov
It was done because "hibernate_after" option already used in ssl for the same reason.
2017-05-02Added support of auto_hibernate_timeout option for gen_server, gen_fsm, ↵Anton N Ryabkov
gen_event process's. There is realized gen_server, gen_fsm, gen_event automatic hibernation functionality. Added unit tests for realized functionality. Added documentation for auto_hibernate_timeout option.

2015-06-18Change license text to APLv2Bruce Yinhe
2014-05-26Add synchronous stop functions to gen_server and gen_fsmSiri Hansen
The functions utilize proc_lib:stop, which in turn utilizes sys:terminate.
2014-03-05stdlib: Improve the doc of the supervisor's via referenceHans Bolinder
Most of the updates have already been made in 'Fix alternative registry type annotations in supervisor', a5412706f4185fddbac29216a49affd1e9f11da0. Thanks to MaximMinin.

2013-04-01Use erlang:demonitor's flush option on timeoutLoïc Hoguin
It is equivalent to the few lines removed, except more efficient.
2013-04-01Don't lookup the node unless required in gen:call/{3,4}Loïc Hoguin
Move some operations that aren't required for the happy path. The operations were small, so they shouldn't show a big difference in benchmarks except for systems with many active gen processes.
2011-11-24Add plugin support for alternative name lookupUlf Wiger
OTP behaviour instances (gen_server, gen_fsm, gen_event) can currently register themselves either locally or globally, and the behaviour libraries (including gen.erl) support both addressing methods, as well as the normal Pid and {Name, Node}. However, there are alternative registry implementations - e.g. gproc - and one can well imagine other ways of locating a behaviour instance, e.g. on a node connected only via a TCP tunnel, rather than via Distributed Erlang. In all these cases, one needs to write extra code to identify the behaviour instance, even though the instance itself need not be aware of how it is located. This patch introduces a new way of locating a behaviour instance: {via, Module, Name}. Module is expected to export a subset of the functions in global.erl, namely: register_name(Name, Pid) -> yes | no whereis_name(Name) -> pid() | undefined unregister_name(Name) -> ok send(Name, Msg) -> Pid Semantics are expected to be the same as for global.erl This can be used in all places where {global, Name} is accepted. faulty export in gen_fsm_SUITE.erl await process death in dummy_via:reset() fix error in gen_[server|fsm]:enter_loop() fix documentation
2011-11-14Remove all use of global:safe_whereis_name/1Hans Bolinder
Calls to global:whereis_name/1 have been substituted for calls to global:safe_whereis_name/1 since the latter is not safe at all. The reason for not doing this earlier is that setting a global lock masked out a bug concerning the restart of supervised children. The bug has now been fixed by a modification of global:whereis_name/1. (Thanks to Ulf Wiger for code contribution.)
2010-07-07Fix format_status bug for unregistered gen_event processesGeoff Cant
Port the gen_fsm code for format_status to gen_event in order to prevent a lists:concat([...,pid()]) crash when calling sys:get_status/1 on an unregistered gen_event process. Refactor format_status header code from gen_* behaviours to module gen. Extend the format_status tests in gen_event_SUITE to cover format_status bugs with anonymous gen_event processes.

* bg/opt-receive: Test that gen_server:call/2,3 are fast even with a huge message queue erts: Add tests for the receive optimization Update primary bootstrap erts: Implement recv_mark/1 and recv_set/1 for real compiler tests: Cover the error handling code in beam_receive compiler test: Test optimization of receive statements Optimize selective receives in the presence of a large message queue Introduce the new recv_mark/1 and recv_mark/1 instructions Compile tests that communicate with R12 nodes with the r12 option Move p_run/2 to test_lib gen: Inline wait_resp_mon/2 to help the compiler optimize OTP-8623 bg/opt-receive reveive statements that can only read out a newly created reference are now specially optimized so that it will execute in constant time regardless of the number of messages in the receive queue for the process. That optimization will benefit calls to gen_server:call(). (See gen:do_call/4 for an example of a receive statement that will be optimized.)
2010-05-10gen: Inline wait_resp_mon/2 to help the compiler optimizeBjörn Gustavsson
We are about to introduce a new optimization that requires the creation of a monitor and the following receive statement to be in the same function.
