2019-04-23kernel: Multiple -sname or -name would be ignoredLukas Larsson
If 'erl -sname 1 -sname 2' is run the node is not started in distribution mode at all. This fix makes the last sname be used.
2019-03-20Testing of the example gen_tcp_dist moduleRickard Green
This also imply testing of processes as distribution controllers using the erlang:dist_ctrl_* BIFs.
2018-09-17Terminate nodes after failed test cases in erl_distribution_SUITESiri Hansen
A hanging node from this suite can fail later tests, so terminate all nodes() after each test case.
2018-07-10kernel: Fix net_kernel:connect_node/1 to local nodeSverker Eriksson
to be no-op and return true as it always has before OTP-21.0.
2018-05-04Add ct:get_progname/0Richard Carlsson
This replaces all uses of lib:progname/0 in tests.
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 The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals.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.

2018-01-24kernel: Ignore cores in erl_distribution_SUITELukas Larsson
Some bash versions segfault when a unicode argument is given so we ignore cores created by nodes spawned by this testcase.
2017-05-24kernel: Make sure to cleanup after distr testsLukas Larsson
Because this test suite did not cleanup after itself, the error_logger_warn_SUITE:file_utc failed to start its node that it needed for the test.

2017-04-28kernel: Do not allow unicode in nodenamesZandra Norman
Verify that unicode isn't used in a node name and logi an info message if it is. Filter the head part of the name a bit harder to work with epmd.

Messages can be lost, but the order is guaranteed. This change weakens the test, but does it according to our guarantees.

Remove out-commented code. Make sure that comments that are not at the end of a line starts with two '%' characters and not just one. That will become important later when we'll remove all ?line macros and ask Emacs to re-indent the files.
