2018-03-20erts: Make sys_memcpy and friends inline functionsSverker Eriksson
to avoid argument-evaluated-twice bugs like in macro DMC_PUSH. Had to shuffle around some #include and #define to make erl_child_setup build debug target.
2018-02-16erts: Ignore SIGTERM in erl_child_setupLukas Larsson
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.

* john/erts/runtime-lcnt: Document rt_mask and add warnings about copy_save Add an emulator test suite for lock counting Break erts_debug:lock_counters/1 into separate BIFs Allow toggling lock counting at runtime Move lock flags to a common header Enable register_SUITE for lcnt builds Enable lcnt smoke test on all builds that have lcnt enabled Make lock counter info independent of the locks being counted OTP-14412 OTP-13170 OTP-14413
2017-07-06Allow toggling lock counting at runtimeJohn Högberg
The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will. OTP-13170
2017-05-29Fix WX lock check assertion on MacOSXRickard Green
The fix avoids registering the main thread as an emulator thread on MacOSX. This since WX steals the main thread for its own usage on MacOSX, and use the thread as an ordinary driver thread.

2017-05-18Make lock counter info independent of the locks being countedJohn Högberg
This allows us to enable/disable lock counting at will, and greatly improves the performance of erts_debug:lock_counters/1 since we no longer have to worry about the lock counters "dying" while we're enumerating them. OTP-14412

2017-03-22erts: Don't allocate memory during signal handlingBjörn-Egil Dahlberg
Allocations and message sending are now scheduled by a signal, via a signal state bitmap, instead of doing it directly in the signal handler.
2017-03-21erts: Make sigterm signal safe for non-smp beamBjörn-Egil Dahlberg
The signal handler will now schedule a sigterm message instead of sending the message in the signal handler. The signal handler must refrain from memory allocations and thus the event is scheduled.
