[erlang-questions] Max heap size

[Lukas Larsson]

Hello everyone,

I recently opened up a new pull request on Github that adds a new
process_flag that can be used to limit the heap size of a process.

https://github.com/erlang/otp/pull/1032

I'd appreciate feedback on the api and semantics of the functionality.

A simple example of the new functionality looks like this:


1> spawn_opt(fun() -> lists:seq(1,10000) end, [{max_heap_size, #{size =>
1024, kill => true, error_logger => true}}]).
<0.66.0>

                        {mbuf_size,0},
                        {recent_size,176},
                        {stack_size,0},
                        {old_heap_size,288},
                        {heap_size,232},
                        {bin_vheap_size,0},
                        {bin_vheap_block_size,46422},
                        {bin_old_vheap_size,0},
                        {bin_old_vheap_block_size,46422}]
