* john/erts/runtime-lcnt: Document rt_mask and add warnings about copy_save Add an emulator test suite for lock counting Break erts_debug:lock_counters/1 into separate BIFs Allow toggling lock counting at runtime Move lock flags to a common header Enable register_SUITE for lcnt builds Enable lcnt smoke test on all builds that have lcnt enabled Make lock counter info independent of the locks being counted OTP-14412 OTP-13170 OTP-14413
2017-07-06Allow toggling lock counting at runtimeJohn Högberg
The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will. OTP-13170
2017-06-15erts: Must have main lock when flushing trace messagesLukas Larsson
If we don't have the main lock, multiple threads may come in and do the flush at the same time which will lead to all kinds of strang problems.
2017-06-14Remove noisy and redundant #ifdefsJohn Högberg
The relevant macros are already guarded by said #ifdefs.
2017-06-14Assert that enqueue_later_op must not run on a dirty scheduler.John Högberg
You're not supposed to do this, but it behaved correctly even with a debug build aside from degraded performance (The scheduler started to busy-wait for new operations rather than sleep).

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.
2017-05-29erl_process.c: Add more assertions in process terminationBjörn Gustavsson
Before terminating a process, add assertions to make sure that all queues for system tasks have been emptied.
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).

2017-04-20erts: Initialize esdp->type in non-smp to normalLukas Larsson
The previous code worked through luck because the memory returned from erts_alloc was zero:ed and SCHED_NORMAL is 0. But if you run with +Meamin that is not always the case which is how this error was detected.
