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.

This fixes a bug where a send/shutdown error on an active-mode socket results
in the port never being properly closed.

(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.
|
|
The garbage_collect message could be received while waiting for trace messages,
causing the test to crash erroneously.

* bjorn/erts/fix-sys-task-cleanup:
erl_process.c: Add more assertions in process termination
Make sure that asynchronous replies are not lost
|
|
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.
|
|
If a link dependency is added in LDFLAGS it should be resolved
in LIBS, so we have to use LIBS and not TYPE_LIBS.
|
|
Before terminating a process, add assertions to make sure that
all queues for system tasks have been emptied.

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).
