2018-03-02kernel,stdlib: Remove obsolete use of send with 'noconnect'Sverker Eriksson
as workarounds to avoid blocking auto-connect, which is now asynchronous in OTP-21. Also changed old catch to more efficient try-catch.
2018-03-02erts,kernel: Add dist_util:strict_order_flags/0Sverker Eriksson
to replace DFLAGS_STRICT_ORDER_DELIVERY and remove that compile time dependency.

and remove use in dist_util:check_mandatory
2018-03-02kernel: Simplify dist flags handshake mergingSverker Eriksson
to a simple 'band' operation into ChosenFlags and no need to remember old 'this_flags' and 'other_flags'.
2018-03-02erts,kernel: Add erts_internal:get_dflags/0Sverker Eriksson
for kernel to ask erts about distribution flags and keep this info in one place.
2018-03-02kernel: Remove redundant codeSverker Eriksson
No need to clear them as they cannot be set.

2018-02-27Skip testing unavailable interfaces in inet_SUITE:getifaddrsJohn Högberg
This test consistently failed on Windows when an interface was enabled but unplugged, as the interface was 'up' but not 'running'.

2018-02-26Allow opening device files and FIFOs with file:open/2John Högberg
To the best of our knowledge this was introduced since file operations on device files/FIFO:s could hang the emulator forever back when the emulator was single-threaded and lacked IO threads; a read operation could block all progress preventing the write operation it waited for from occurring. Granted, this could still happen through starving all dirty IO schedulers, but the same issue can arise with NFS files which we've always allowed. Removing this restriction also lets us remove a stat(2) call that was added to specifically allow `/dev/null`.

2018-02-21erts: Optimize erlang:put/2 for immed valuesSverker Eriksson
Do destructive write of immed value if key exists. This is an optimization at the expense of get/0 which must now copy all (mutable) key-value tuples.

2018-02-02Reword docs related to the runtime system modeXavier Noria
The existing wording may be interpreted as saying that embedded mode eager loads all modules. This revision makes clear embedded mode only disables module auto loading. Since I was on it, I have reordered a couple of places to describe interactive first, and then embedded. It feels natural to cover first the default and positive mode (auto loads), and then its negation.
2018-01-29make HiPE work on x86_64 when PIE is enabledbhuztez
Currently HiPE amd64 assumes the runtime system code is loaded into the low 2G of the address space. However, this is not the case when PIE is enabled, it is loaded into a random location. So trampolines are required to call BIFs, and also we have first to load the address of sse2_fnegate_mask to a regisiter before xorpd in fchs.

2018-01-17Fix slow hipe executionSverker Eriksson
particularly slow erlc when compiler is hipe compiled. hipe_unified_loader:load did not patch external call sites and instead caused a double hipe mode switch per call. hipe_unified_loader:load is only used for early modules first loaded as beam and by code:atomic_load and friends.

2018-01-05stdlib: Let filelib:find_source() search subdirsHans Bolinder
The Design Principles states that an application can have Erlang source files one level below the "src" directory, and now filelib:find_source() by default searches one level below "src". The same applies to "esrc". That directory is only mentioned in filename(3).
2018-01-03Disallow NULs in filename-encoded stringsJohn Högberg
Previously we accepted trailing NULs, which was backwards compatible as such usage never resulted in misbehavior in the first place. The downside is that it prevented erts_native_filename_need from returning an accurate number of *actual characters*, needlessly complicating encoding-agnostic code like erts_osenv.
2018-01-03Replace the libc environment with a thread-safe emulationJohn Högberg
putenv(3) and friends aren't thread-safe regardless of how you slice it; a global lock around all environment operations (like before) keeps things safe as far as our own operations go, but we have absolutely no control over what libc or a library dragged in by a driver/NIF does -- they're free to call getenv(3) or putenv(3) without honoring our lock. This commit solves this by setting up an "emulated" environment which can't be touched without going through our interfaces. Third-party libraries can still shoot themselves in the foot but benign uses of os:putenv/2 will no longer risk crashing the emulator.
