The types in erl_parse.yrl are more in harmony with the description in The Abstract Format (in ERTS User's Guide).

* mm/stdlib/ord-docs/PR-1242: Document the ordering used in ordsets and orddicts
2016-11-18Document the ordering used in ordsets and orddictsMichal Muskala
Right now the exact order of elements is not specified, yet many programs rely on the ordering being the obvious one - erlang term order. It is only beneficial to make this an explicit part of the documentation.

2016-11-17Correct tar_SUITE:unicode/1Björn Gustavsson
Make sure that we always test the "+fnu" option on all systems. It seems that it was not tested in our daily builds, since they are run non-interactively. Make sure that we sort the list of names in do_unicode/1. Otherwise the test would only work in "+fnl" mode because the list would only contain one element.

2016-11-14Add jump functions to rand moduleKenji Rikitake
Jump functions returns the state after performing jump calculation to a rand module internal state, which is equivalent to perform a large number of calls of calculating new states for XorShift*/+ algorithms. This commit add jump functions for exsplus and exs1024 algorithms, and a wrapper function jump/1. The wrapper function will cause error with reason "not_implemented" if the jump function for the algorithm is not implemented. This commit adds following new functionalities: - Add new functions rand:jump/0 and rand:jump/1 - Add the member jump to type alg_handler(), a fun for performing the jump function - Add jump functions for exsplus, equivalent to 2^64 calls - Add jump functions for exs1024, equivalent to 2^512 calls - Revise seed_put/1, seed/1, seed/2 See <https://github.com/erlang/otp/pull/1235#discussion_r86950557> - Add dummy jump function for exs64 calling erlang:error(not_implemented) - Add jump function test cases as follows: * Add Common Test group reference_jump * Add tests for jump/0 to reference_jump_procdict/1 * Rename tests for jump/1 to reference_jump_state/1 * Rename gen_jump/1 to gen_jump_1/1 * Add Common Tests reference_jump_procdict and reference_jump_state to the group reference_jump - Add jump function documentation This commit also changes the Copyright year for Kenji Rikitake's code from 2015 to 2015-2016.

2016-11-08Speed up sets:add_element/2 and sets:del_element/2Mikhail Yashkov
Optimize sets:add_element/2 when adding an element that is already present, and sets:del_element/2 when the element to be deleted is not present. This optimization can make certain operations, such as sets:union/2 with many overlapping elements, up to two orders of magnitude faster.

2016-10-31Propagate exceptions fully when using proc_libLoïc Hoguin
This makes proc_lib behaves like a normal process as far as the propagation of exceptions is concerned. Before this commit, the following difference could be observed: 6> spawn_link(fun() -> ssl:send(a,b) end). <0.43.0> 7> flush(). Shell got {'EXIT',<0.43.0>, {function_clause, [{ssl,send,[a,b],[{file,"..."},{line,275}]}]}} ok 8> proc_lib:spawn_link(fun() -> ssl:send(a,b) end). <0.46.0> 9> flush(). Shell got {'EXIT',<0.46.0>,function_clause} After this commit, we get the following instead: 3> flush(). Shell got {'EXIT',<0.61.0>, {function_clause, [{ssl,send,[a,b],[{file,"..."},{line,275}]}, {proc_lib,init_p,3,[{file,"..."},{line,232}]}]}} The stacktrace will show minor differences of course but the form is now the same as without proc_lib. The rationale behind this commit is that: * We now have a single form regardless of how the process was started * We can use the stacktrace to programmatically alter behavior (for example an HTTP server identifying problems in input decoding to send back a generic 400, or a 500 otherwise) * We can access the stacktrace to print it somewhere (for example an HTTP server could send it back to the client when a debug mode is enabled)

Do not start an event timer unless there are no enqueued events.
2016-10-26Rework timeout handlingRaimo Niskanen
Handling of timers and timeouts has been cleaned up and generalized. Semantic change regarding state timeout zero: Previously if one state caused a state timeout zero and managed to stay in the same state to insert additional timeout zero(s) in the next state callback invocation, then there would be only one timeout zero event. The mindset was that the machine was faster then the timeout zero. This has changed with the mindset that all state callback invocations should be independent, so now the machine will get one state timeout zero event per started state timeout zero. Note that just using zero timeouts is fairly esoteric...

2016-10-13dbg:fun2ms: allow empty list as headPéter Gömöri
Running 'dbg:fun2ms(fun([]) -> return_trace() end' resulted in an error "dbg:fun2ms requires fun with single variable or list parameter" But the empty list is actually a list and it is a valid value as a match-spec head (matching on arity-0 functions). Although its practical use is questionable this commit eliminates a small limitation of ms_transform which is not present in the match-spec grammar.
