* nybek/speed_up_supervisor_count_children: Speed up supervisor:count_children/1; simple_one_for_one Add supervisor:get_callback_module/1 OTP-13290
2016-02-03Speed up supervisor:count_children/1; simple_one_for_oneRory Byrne
Speed up supervisor:count_children/1 for simple_one_for_one supervisors. This is achieved by avoiding looping through all the child process and verifying that each one is alive. For a supervisor with 100,000 'temporary' children the count-time will drop from approx 25ms to about 0.005ms. For a supervisor with 100,000 'permanent' or 'transient' children the count-time will drop from approx 30ms to about 0.005ms. This avoids having the supervisor block for an extended period while the count takes place. Under normal circumstances the accuracy of the result should also improve since the duration is too short for many processes to die during the count.
2016-01-20Introduce time warp safe replacement for safe_fixed optionRickard Green
The new time warp safe option is safe_fixed_monotonic_time which gives erlang:monotonic_time(). The safe_fixed option was also slightly changed. It now gives erlang:timestamp() instead of erlang:now(). This has however not been documented, so it is considered a compatible change. The above effects both ets, and dets. This commit also include the bugfix OTP-13239 for dets:info(Tab, safe_fixed). The timestamp in the result returned by dets:info(Tab, safe_fixed) was unintentionally broken as a result of the time API rewrites in OTP 18.0.

2015-06-15dialyzer: Modify the handling of parametrized opaque typesHans Bolinder
In OTP 17 it is possible to mix types such as dict:dict() and dict:dict(_, _) outside of the dict module (and similarly for some other opaque types in STDLIB), but the results are unfortunately possibly invalid warnings in users' code. In OTP 18 parameterized opaque types with the same name but with different number of parameters are no longer compatible when seen from outside of the module where the types are declared. The types in STDLIB have been updated accordingly; for instance -opaque dict() :: dict(_, _). has been replaced by -type dict() :: dict(_, _).
2015-06-03Break out assert macros from eunit to stdlib assert.hrlRichard Carlsson
Several people have requested that the assert macros in EUnit should be moved out to a separate header file. This patch puts them in stdlib/include/assert.hrl, which gets included by the eunit.hrl file. Thus, nothing changes for eunit users, but the asserts can now also be included separately.

* fishcakez/supervisor_ignore: Don't store child that returns ignore in simple supervisor OTP-12793
2015-05-29Update orddict with parameterized types and specsUENISHI Kota
With parametrized types and specs, modules using orddict can be statically checked with dialyzer. Although orddict have not been builtin types, it is good and more natural to have its exported types and specs aligned to builtin types.
2015-05-26Don't store child that returns ignore in simple supervisorJames Fish
If a child of a simple_one_for_one returns ignore from its start function no longer store the child for any restart type. It is not possible to restart or delete the child because the supervisor is a simple_one_for_one. Previously a simple_one_for_one would crash, potentially without shutting down all of its children, when it tried to shutdown a child with undefined pid. Previous only one undefined pid child was stored in a simple_one_for_one supervisor no matter how many times the child start function returned ignore.

Introduce erl_anno, an abstraction of the second element of tokens and tuples in the abstract format. The convention that negative line numbers can be used for silencing compiler warnings will no longer work in OTP 19; instead the annotation 'generated' is to be used.
