2018-04-26[stdlib/sys]: install one debug function more times (#1781)Pouriya
Allow installing multiple instances of sys debug function This commit solves a bug which allowed installing {Fun,State} as sys debug function even if Fun was already installed. This happened in the case when the current State of the debug fun was undefined. Also, the new format {Id,Fun,State} of debug functions can be installed, allowing multiple instances of the same fun.

2018-04-26stdlib: Add RFC 3339 functions to module calendarHans Bolinder
Functions for converting between RFC 3339 strings and system time are added. Options are lists, but we are considering using maps instead. If we change, it will happen after Erlang/OTP 21.0-rc1 is released.

2018-04-25stdlib: Modify the printing of map associations with wWpPHans Bolinder
Use the same depth for all (printed) elements of a map. Since the order of keys can vary when printing a map--maps:iterator/1 and maps:next/1 are used--it is more consistent to print all associations with the same depth. If the associations printed are limited by the depth, the selection of associations is arbitrary, as before.
2018-04-25stdlib: Introduce characters limit of formated stringsHans Bolinder
Inspiration from module lager_format. Also some improvements of Unicode handling. io_lib:format/3 and io_lib:fwrite/3 are new functions. The representation of the options is a list, but we are considering using a map instead. If we change, it will happen after Erlang/OTP 21.0-rc1 is released.
2018-04-25stdlib: Modify ~w/~W when number of characters is limitedHans Bolinder
A bug fix: limited maps end with "...", not "...=>...". A modification: wW separate pairs with " => ", not "=>". When the output is limited on number of characters, the term is balanced by wW the same way as is done with pP (see commit bc38638).
2018-04-25stdlib: Introduce characters limit of formatted stringsHans Bolinder
The name of the io_lib_pretty:print/2 option 'max_chars' is changed to 'line_max_chars' (used by module shell only). The new option for limiting the number of returned characters of io_lib_pretty:print() is called 'chars_limit'.

2018-04-23Fix sys's debug statistics.Boshan Sun
Currently, in sys:stat/2, the message out only count for system events with format {out, Msg, To}. However, the gen_server:reply/5 will call sys:handle_debug/4 with format {out, Reply, To, State}. That will make the message out count fail to pattern matching. Also update sys_SUITE.erl and relevant docs.

Implementation of true asynchronous signaling between processes
2018-03-21Implementation of true asynchronous signaling between processesRickard Green
Communication between Erlang processes has conceptually always been performed through asynchronous signaling. The runtime system implementation has however previously preformed most operation synchronously. In a system with only one true thread of execution, this is not problematic (often the opposite). In a system with multiple threads of execution (as current runtime system implementation with SMP support) it becomes problematic. This since it often involves locking of structures when updating them which in turn cause resource contention. Utilizing true asynchronous communication often avoids these resource contention issues. The case that triggered this change was contention on the link lock due to frequent updates of the monitor trees during communication with a frequently used server. The signal order delivery guarantees of the language makes it hard to change the implementation of only some signals to use true asynchronous signaling. Therefore the implementations of (almost) all signals have been changed. Currently the following signals have been implemented as true asynchronous signals: - Message signals - Exit signals - Monitor signals - Demonitor signals - Monitor triggered signals (DOWN, CHANGE, etc) - Link signals - Unlink signals - Group leader signals All of the above already defined as asynchronous signals in the language. The implementation of messages signals was quite asynchronous to begin with, but had quite strict delivery constraints due to the ordering guarantees of signals between a pair of processes. The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals. More details regarding the signal queue can be found in comments in the erl_proc_sig_queue.h file. The monitor and link implementations have also been completely replaced in order to fit the new asynchronous signaling implementation as good as possible. More details regarding the new monitor and link implementations can be found in the erl_monitor_link.h file.
