2017-06-07erts: Fix sendfile closeduring scenario on sunosLukas Larsson
On Solaris, giving a too long sfv_len results in an EINVAL error, but data is still transmitted and len is correctly. So we translate this to a success with that amount of data sent. This may hide some other errors that causes EINVAL, but it is the best we can do for now.
2017-06-03Stabilize call_with_huge_message_queue/1Björn Gustavsson
Time measurements are always tricky, particulary on virtual hosts. On one particular virtual host, the measured times were often 0. Measuring the time for 100 calls instead of 10 calls helps, but 0 can still be returned, so we will also need to discard measurements that return 0 and try again.
2017-06-03same_time_yielding/1: Avoid failing if there are many schedulersBjörn Gustavsson
On a computer with 32 schedulers, there would be 9632 (301*32) 'timeout' message in the receive queue. Receiving them with a selective receive (matching on the timer ID) is quite slow. Change the test case to read out the queue in the order the messages are stored in the queue.
2017-06-03Remove obsolete old_scheduler_SUITEBjörn Gustavsson
old_scheduler_SUITE was written before the SMP emulator. It does not test anything that scheduler_SUITE does not test. Keeping it wastes time when running the emulator test suite, and does not help us find any bugs that scheduler_SUITE would find.
2017-06-03Robustify process_SUITE:spawn_opt_max_heap_size/1Björn Gustavsson
process_SUITE starts os_mon in init_per_suite/1. Therefore, there may be occasional alarm info messages received. Make sure that they are ignored and don't cause the test fail to fail. Also, get rid of the flush/0 function that discards all messages in the message queue. Instead, be more selective and only discard {error, ...} messages.
2017-06-03Contain damage cause by spawn_opt_max_heap_size failingBjörn Gustavsson
If process_SUITE:spawn_opt_max_heap_size/1 failed, the default value for the maximum heap size could have been changed. That would cause other test cases that spawned huge processes to fail. Contain the damage by always restoring the default value for max_heap_size in end_per_testcase/2.
2017-06-03Make bulk_send_bigbig/1 purely informationalBjörn Gustavsson
bulk_send_bigbig/1 sometimes fails even if there is nothing wrong. Stop testing the ratio, and just return information about the speed and number of monitor messages. The testcase will still serve as a smoke test of the +zdbbl option.

Refactor bulk_send_bigbig/1 to make it somewhat easier to follow.

2017-06-03Lengthen too short timetrapsBjörn Gustavsson
c062dfc485a added timetraps to test suites that had no timetraps. Some of added timetraps are only 5 or 10 seconds, which is can be too short time on some slow computers. Change those times to one or two minutes.
2017-06-03Fix process_SUITE:low_prio/1Björn Gustavsson
It is expected that low-priority processes should be allowed to run about 1/8 of the time of normal-priority processes. The proportion calculated was usually considerably lower than 1/8. It seems that the main reason is the punishement in reductions when sending to a process that alreday has many messages in the message queue. I have verified that by running the emulator with the +snsp to turn off the send punishment. To avoid that punishment, let the server process run at high priority so that it can keep its message queue short. It seems that the proportion is now very close to 1/8. Therefore, we can tighten the margins for the proportion.

2017-05-31Make sure that asynchronous replies are not lostBjörn Gustavsson
(First attempt to fix in 23f132d9ab776a.) If an synchronous GC was requested by calling: erlang:garbage_collect(Pid, [{async,Ref}]) the reply message could in certain circumstances be lost. The problem is that cleanup_sys_tasks() is never called if there are dirty tasks, but no other active system tasks. Also shorten the long waiting times in the test case binary_SUITE:trapping/1 to make it much more likely that the GC have not already finished when the process is killed.
2017-05-31Fix a race condition that consistently affected lc+lcnt buildsJohn Högberg
The garbage_collect message could be received while waiting for trace messages, causing the test to crash erroneously.

2017-05-29Fix WX lock check assertion on MacOSXRickard Green
The fix avoids registering the main thread as an emulator thread on MacOSX. This since WX steals the main thread for its own usage on MacOSX, and use the thread as an ordinary driver thread.

2017-05-29Make sure that asynchronous replies are not lostBjörn Gustavsson
If an synchronous GC was requested by calling: erlang:garbage_collect(Pid, [{async,Ref}]) the reply message could in certain circumstances be lost. The problem is in cleanup_sys_tasks() in erl_process.c. If there were at least one dirty task, only the first dirty task would be cleaned up. All other systems tasks would not be cleaned up (that is, no replies would be sent to other processes waiting for the tasks to finish).
