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 The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals.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.

Can not start via rpc any more without spawning a keep alive process, since it will stop collecting when process dies.

This commit also adds a check to see that all files that are part of an xi:include also have part of XML_FILES and vice versa. It also fixes any applications where this was not true.

rb would fail to show an error_logger report which was not a list. This is now corrected and any term is allowed (as specified in the error_logger reference manual).

2017-09-27Do not load .erlang from current dirDan Gudmundsson
It may be confusing that "hidden" .erlang is loaded from the current working directory. Use c:erlangrc([Dir1,..]) to search and load .erlang from other places than "$HOME/.erlang". Implies that c:erlangrc() needs to be documented.

This can now be explicitly set by the 'sasl_error_logger' configuration parameter, but if not set, the default encoding is now utf8. When printing to this log, the Unicode translation modifier, t, might be used in the format string.

2017-05-30Update sasl_report_SUITE to accept new size of sasl.logSiri Hansen
PR-1448 caused sasl_report_SUITE:gen_server_crash to produce a slightly bigger sasl.log. This is because the Reason used in the crash report is changed from {ExitReason,Stacktrace} to ExitReason only, where ExitReason={badmatch,BigGbSet}. The term is written with a depth limit of 30, and when removing the top tuple, a new level of the gb_set is exposed. This level contains more data than the removed Stacktrace, and thus the resulting log gets a bit bigger than before.
