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 The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals.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

2016-07-11[reltool] Fix dependency bug for applications in 'rel' specsSiri Hansen
For applications that are included in a 'rel' spec in the reltool config, some dependency chains are not followed. E.g. * Application x has y as included application, and y in turn has z as included application. Then z is not included. * Application x has y in its 'applications' tag in the .app file, and y in turn has z as included application. Then z is not included. This is now corrected - all app-file dependencies are recusively followed for all applications that are included in a 'rel' spec in the reltool config.

2016-03-31reltool_server_SUITE: Correct diffing of start scriptsBjörn Gustavsson
In c3c6182, systools was updated to add more modules to be pre-loaded along with error_handler. That is a pure optimization. Because of the extra modules, test cases that compared the start scripts generated by SASL with the ones generated by Reltool would fail. We must implement a more elaborate way to diff the scripts.
