2019-02-14erts: Avoid heart killing a nicely exiting emulatorSverker Eriksson
Symptom: Heart kills exiting emulator before is has flushed all ports and with HEART_KILL_SIGNAL=SIGABRT it may also produce unnecessary core dumps from doing init:reboot() for example. Problem: Heart port is closed together with all the others in handle_reap_ports() which is detected by heart OS process. Solution 1: Leave the heart port alone in handle_reap_ports() and let it be closed by OS when emulator exists. It doesn't need to be flushed anyway. Solution 2: When heart OS process gets EOF on connection let it wait max 5 seconds for emulator process to self terminate before trying to kill it.

2018-05-24Fix use-after-free on Windows in escriptBenedikt Reinartz
Since commit 385b18de6fd72672ed7d6736b30f56d6691d4433, the emulator path was not copied anymore before pushing it to the args vector (before it was done within the `push_words` function. Since on Windows `free_env_val` is not a NOP as it is on Unix systems, the string is freed and afterwards used, leading to strange errors like this: escript: Error executing 'àyI': 2 This is fixed by removing the `free_env_val` call.

2018-04-24heart: Use ntohs instead of manual conversionJohn Högberg
Multiplying a signed char by 256 is undefined behavior and caused problems on some platforms when the length was long enough. We could cast it to an unsigned int to make it work, but it's best not to reinvent the wheel. Fixes OTP-15034
2018-04-23erts: Rewrite memory instrumentationJohn Högberg
This commit replaces the old memory instrumentation with a new implementation that scans carriers instead of wrapping erts_alloc/erts_free. The old implementation could not extract information without halting the emulator, had considerable runtime overhead, and the memory maps it produced were noisy and lacked critical information. Since the new implementation walks through existing data structures there's no longer a need to start the emulator with special flags to get information about carrier utilization/fragmentation. Memory fragmentation is also easier to diagnose as it's presented on a per-carrier basis which eliminates the need to account for "holes" between mmap segments. To help track allocations, each allocation can now be tagged with what it is and who allocated it at the cost of one extra word per allocation. This is controlled on a per-allocator basis with the +M<S>atags option, and is enabled by default for binary_alloc and driver_alloc (which is also used by NIFs).
