2017-01-05erts: Add SIGHUP signal handlerBjörn-Egil Dahlberg
A received SIGHUP signal to beam will generate a '{notify, sighup}' message to the registered process 'erl_signal_server'. 'erl_signal_server' is a gen_event process.

2016-11-17erts: Add ErtsStrToSint64Sverker Eriksson
for simplify string to 64-bit integer parsing.
2016-11-17erts: Refactor crash dumping with cbprintfSverker Eriksson
Instead of passing around a file descriptor use a function pointer to facilitate more advanced backend write logic such as size limitation or compression.

Do not generate a core when a crashdump is asked for. Regression introduced in 56090db3ea417157a749bdd810fc61d117493f1f
2016-10-21erts: Use mprotect for hipe on all arch except x86_64Sverker Eriksson
Only x86_64 needs to reserve low virtual memory for its amd64 small code model.
2016-10-14erts: Enable exec_alloc for all hipe architecturesSverker Eriksson
For non-amd64 it's a "normal" allocator with a wrapper around mseg_alloc to call mprotect(PROT_EXEC).

2016-09-02erts: Fix child setup signal hander bugLukas Larsson
When running the signal handler, the errno has to be restored to its original value, otherwise code running in the same thread may misbehave.

2016-07-01erts: Fix HARD_DEBUG printouts in erl_child_setupLukas Larsson
2016-07-01erts: Improve error printouts in erl_child_setupLukas Larsson
Add prints to stderr with a small description of the error so that errors will be easier to debug. Also if a protocol error is detected, erl_child_setup will abort instead of exit.
2016-06-28erts: Save abort reason for erl_child_setupSverker Eriksson
Nice to have for core dump inspection when stderr -> /dev/null.
2016-06-22Improve accuracy of timeouts using premature timeoutsRickard Green
Improve accuracy of timeouts using a premature timeout then return to sleep with a shorter timeout just before requested timeout. This approach is only used on certain platforms where we know it improves the accuracy of the timeouts, e.g. MacOS X.

2016-06-20erts: Optimize spawn driver for large(r) environmentsSverker Eriksson
that need to be enqueued.
2016-06-20erts: Fix spawn driver when env size is above pipe capacitySverker Eriksson
Symptom: open_port() succeeds, port program never starts but instead seem to terminate with exit_status 150 (EINVAL+128). When: If the command payload buffer (including the entire environment) for the port program is between 1 to 4 bytes above the pipe capacity, which is 65536 bytes on newer Linux, but can be as low as 4096 on older 32-bit Linux. Since: OTP-19.0-rc1.

2016-06-10Disregard MAP_NORESERVE for FreeBSDKenji Rikitake
A fix for running 19.0-rc2 on FreeBSD with HiPE enabled. * erl_mmap.h: disregard MAP_NORESERVE for FreeBSD MAP_NORESERVE is undefined in FreeBSD 10.x and later. This is to enable 64bit HiPE experimentally on FreeBSD. Note that on FreeBSD MAP_NORESERVE was "never implemented" even before 11.x (and the flag does not exist in /usr/src/sys/vm/mmap.c of 10.3-STABLE r301478 either), and HiPE was working on OTP 18.3.3, so mandating MAP_NORESERVE on FreeBSD might not be needed. See the following message on how MAP_NORESERVE was treated on FreeBSD: <http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20150202/122958.html> * erl_mmap.c: disable MAP_NORESERVE for FreeBSD * See also <https://github.com/erlang/otp/pull/925/commits/b02ce940c8738785ad018c9f758ca0d05d256bbb>
