2016-04-04Handle multi-giga byte writes to filesBjörn Gustavsson
Test cases that write 4Gb to a file at once would fail on OS X and FreeBSD. By running a simple test program on OS X (El Capitan 10.11.4/Darwin 15.4.0), I found that writev() can handle more than 4Gb of data, while write() only can handle less than 2Gb. (Note that efile_drv.c will use write() if there is only one element in the io vector, and writev() if there is more than one.) It is tempting to attempt to piggy-back on the existing mechanism for segmenting write operations in efile_drv.c, but because of the complex code I find it too dangerous, both from a correctness and performance perspective. Instead do the change in unix_efile.c, which is considerably simpler.

2016-04-01erts: Fix race for process_flag(trap_exit,true)Sverker Eriksson
and a concurrent exit signal. We now actually guarantee that the process will not die from exit signal *after* the call to process_flag(trap_exit,true) has returned. The race is narrow and probably quite hard to observe even if you manage to provoke it. Has only been confirmed with the help of return trace and a sleep in send_exit_signal(). Solution: Seize status lock to prevent send_exit_signal() from reading an old status (without TRAP_EXIT) and then writing PENDING_EXIT after TRAP_EXIT has been set by process_flag_2().
2016-04-01erts: Don't search for non-existing Map keys twiceBjörn-Egil Dahlberg
* For maps:get/2,3 and maps:find/2, searching for an immediate key, e.g. an atom, the search was performed twice if the key did not exist in the map.

2016-03-29Don't send unasked for systemd notificationsAlexey Lebedeff
Suppose we have some erlang system that uses systemd unit with Type=notify - so this should send startup confirmation itself. But if systemd-enabled epmd will be started as a first step of that system startup, empd startup confirmation will be misinterpeted by systemd. And our erlang service will be considered 'ready' to early. Also this will interefere with systemd MAINPID detection: systemd will be monitoring `epmd` process instead of `beam` one. For example, rabbitmq works around this issue by starting epmd using separate short-lived beam process, with NOTIFY_SOCKET environment variable reset - only in this way we could be sure that epmd will not interfere with rabbit startup sequence. This patch disables indiscriminate confirmation sending, and does it only when it was explicitly asked to do so.

2016-03-29erts: inline tag_val_defLukas Larsson
The tag_val_def function was called and multiple switch statements had to be traversed in term.c, and then a big switch in the calling code to branch on the term types. By inlining the switches are merged by the compiler and a lot fewer branches have to be taken. Benchmarks show that this increases performance of enc_term by as much as 10%.
