2019-02-01erts: Remove dead ERTS_MAGIC_REF_BIF_TIMERS codeLukas Larsson
Using magic refs for big timers caused too large a stress on the off_heap GC implementation to be viable, so it was never enable. The code is now broken because of other changes to we might as well remove it.

2019-01-30erts: Fix compiler warning for IS_SSMALLSverker Eriksson
"shift count negative or too big, undefined behavior"
2019-01-30Fix bug in binary:encode_unsigned causing a read of uninitialized memoryKjell Winblad
The bug could be seen by running the test that is added by this commit in a valgrind enabled emulator. Co-authored-by: John Högberg <[email protected]>
2019-01-30[socket-nif] Preliminary windows adaptionsMicael Karlberg
Added preliminary, and temporary, windows adaptions. Basically they amount to letting all nif-callback functions returning badarg for all calls if on windows (this has been accomplished by if-defing the nif-code; if win32 then badarg else do-something). OTP-15526
2019-01-29[socket-nif] The otp rcvbuf option updatedMicael Karlberg
Its now possible to set a rcvbuf (otp) option value of {N :: pos_integer(), BufSz :: pos_integer()}. This value is used for type stream and protocol tcp, when calling the function recv with length = 0 (zero). The second value, BufSz, is the actual size of the receive buffer used when calling the socket recv function, and the first value, N, is the max number of possible reads that will be performed (at most), even if there is more data to read. This is limit the effect of DoS attacks. OTP-15497
2019-01-28erts: Add magic port control numbersSverker Eriksson
to increase the probablity of a nice badarg from erlang:port_control.
2019-01-28Add -ztma option for enabling tuple callsRichard Carlsson
2019-01-28Reinstate tuple calls support in the beam emulatorRichard Carlsson
This reverts commit f2b332186a for beam_emu.c only, to enable an upgrade path for existing beam code compiled under OTP 20 with parameterized modules.
2019-01-25[socket-nif] Correct state checks when calling read and write functionsMicael Karlberg
The read and write functions now *only* use the isReadable and isWritable fields, respectively, to decide if the "socket" can be read from and written to (previously the state field was used outside of the mutex lock). Also made it possible to enable / disable test suite groups individually, via environment variables (ESOCK_TEST_...). Specifically, the ttest group has been excluded by default (takes to long a time). OTP-15549

Apply type optimizations across local function calls

This commit lets the type optimization pass work across functions, tracking return and argument types to eliminate redundant tests.

2019-01-21[socket-nif] Add support for otp option fdMicael Karlberg
Add a way to *get* the file descriptor (fd) of a socket. Useful mostly for debugging. OTP-15528
2019-01-21Optimize the is_function/2 guard testBjörn Gustavsson
The is_function2 instruction is executed surprisingly frequently when running dialyzer or the compiler. It cannot hurt to optimize it a little.
2019-01-21erts: Fix getting of poll events on linux >= 4.15.0Lukas Larsson
2019-01-18erts: Use reduction based polling for starved poll-setLukas Larsson
When the schedulers never go to sleep (and thus never polls) it may be that the fds in schedulers poll-sets are never polled. Before this commit, this was solved by starting a timer when an overload was detected. This had issues as overloads were not always detected in time. So this commit reverts to the pre OTP-21 behaviour so keep a global counter makes that the poll is called when it should.

There seems to be an incorrect merge conflict resolution in abde22933f5a that merged maint to master. Dumping of references (and possibly other terms) were broken.
