erl_child_setup is linked together with hash.o so we need to
inline any functions into it when running in debug mode.
|
|
|
|
The functions io:columns() and io:rows() only worked correctly inside
interactive erlang shells before this fix. These functions returned
{error,enotsup} before this fix even if stdout and stdin were
connected to a terminal when they were invoked from an escript or a
program started with e.g., `erl -noshell`.
This commit fixes issue ERL-717.

The poll code for kevent on OpenBSD and NetBSD had not been fixed
to work properly when disabling events in the scheduler poll-set.
Because they use ONESHOT the delete operation was built into the
trigger and thus a lot of code was not needed when doing oneshot,
however it is needed when doing non-oneshot.

Incorrect precidence rules made the driver never
deselect the given fds.

inet_drv adds some arcane #defines to get SCTP working, which may
end up disabling madvise(2) locally in that file, breaking the
build in the process.
This commit disables madvise(2) altogether on Solaris as it's
far simpler than undoing the define dance in erl_mmap.h.

jhogberg/john/erts/mark-pooled-free-blocks-unused/OTP-15075
Mark free blocks in pooled carriers as unused
|
|
This lets the OS reclaim the physical memory associated with these
blocks which reduces the impact of long-lived awkward allocations.
A small allocated block will still keep a huge carrier alive, but
the unused part of the carrier will now be available to the OS.

At start of the VM a poll-set that the schedulers
will check is created where fds that have triggered
many (at the moment, many means 10) times without
being deselected inbetween. In this scheduler specific
poll-set fds do not use ONESHOT, which means that the
number of syscalls goes down dramatically for such fds.
This pollset is introduced in order to handle fds that
are used by the erlang distribution and that never
change their state from {active, true}.
This pollset only handles ready_input events,
ready_output is still handled by the poll threads.
During overload, polling the scheduler poll-set is done
on a 10ms timer.

The poll thread does a lot of waking up and then going
back to sleep. A large part of the waking up is managing
thread progress and a large part of that was using thread
specific data to get the thread progress data pointer.
With this refactor the tpd is passed to each of the functions
which greatly decreases the number of ethr_get_tsd calls
which in turn halves the CPU usage of the poller thread in
certain scenarios.

erl_child_setup program ignores TERM signals as of ERTS version
10.0 (cff8dce0). This setting was unfortunately inherited by
port programs. This commit restores handling of TERM signals
in port programs to the default behavior. That is, terminate the
process.

A lot of erts internal messages used behind APIs to create
non-blocking calls, e.g. port_command, would cause the seq_trace
token to be cleared from the caller when it should not.
This commit fixes that and adds asserts that makes sure
that all messages sent have to correct token set.
Fixes: ERL-602

Before this change, if a write to the uds failed due to
EMFILE to ETOOMANYREFS the entire vm would crash. This
change makes it so that an SIGCHLD is simulated to that
the error is propagated to the user instead of terminating
the VM.
