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).
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.

2017-12-05Ensure that bindir is first in $PATH on startupJohn Högberg
erlexec adds $ROOT/erts-<vsn>/bin and $ROOT/bin first in $PATH on startup, but didn't do so if they were in the $PATH already, which meant that the bindir didn't point to the current release after a downgrade.

2017-10-13erts: Use PROFILE dir as home on windowsLukas Larsson
Instead of using C:\Windows we use the profile path as the home path on windows. The profile path normally resolves to C:\Users\%USERNAME%. This fixes an issue where the default path to the .erlang.cookie was not the same for jinterface as for erl.

2017-05-16Teach erlexec the -emu_type optionBjörn Gustavsson
Add the option -emu_type to start an emulator of a certain type. For exampe, "-emu_type lcnt" will start beam.lcnt.smp. Any string will be accepted after -emu_type. If there is no corresponding emulator, there will be an error similar to: erlexec: The emulator '.../bin/x86_64-unknown-linux-gnu/beam.foo.smp' does not exist. On Windows, there is an undocumented option "-debug". Remove that option, because -emu_type can be used instead.
