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.

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).

2018-03-26Add +sbwt/+swt analogues for dirty schedulersJohn Högberg
Sharing these settings for all schedulers can degrade performance, so it makes sense to be able to configure them separately. This also changes the default busy-wait time to "short" for both kinds of dirty schedulers.
2018-03-21Implementation of true asynchronous signaling between processesRickard Green
Communication between Erlang processes has conceptually always been performed through asynchronous signaling. The runtime system implementation has however previously preformed most operation synchronously. In a system with only one true thread of execution, this is not problematic (often the opposite). In a system with multiple threads of execution (as current runtime system implementation with SMP support) it becomes problematic. This since it often involves locking of structures when updating them which in turn cause resource contention. Utilizing true asynchronous communication often avoids these resource contention issues. The case that triggered this change was contention on the link lock due to frequent updates of the monitor trees during communication with a frequently used server. The signal order delivery guarantees of the language makes it hard to change the implementation of only some signals to use true asynchronous signaling. Therefore the implementations of (almost) all signals have been changed. Currently the following signals have been implemented as true asynchronous signals: - Message signals - Exit signals - Monitor signals - Demonitor signals - Monitor triggered signals (DOWN, CHANGE, etc) - Link signals - Unlink signals - Group leader signals All of the above already defined as asynchronous signals in the language. The implementation of messages signals was quite asynchronous to begin with, but had quite strict delivery constraints due to the ordering guarantees of signals between a pair of processes. The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals. More details regarding the signal queue can be found in comments in the erl_proc_sig_queue.h file. The monitor and link implementations have also been completely replaced in order to fit the new asynchronous signaling implementation as good as possible. More details regarding the new monitor and link implementations can be found in the erl_monitor_link.h file.
