2017-09-14Document that the compiler may optimize away atomsBjörn Gustavsson
The following code could fail in the call to list_existing_atom/1: String = atom_to_list(some_atom), Atom = list_to_existing_atom(String) because the compiler will rewrite the code to: String = "some_atom", Atom = list_to_existing_atom(String) If some_atom is not used in another place, it will not exist. The compiler could be updated to preserve the atom in this simple case, but it would be hard to make sure that the compiler never loses atoms that exist in the source text. It also difficult to imagine a real world use case where this would be a problem. If an atom is mentioned only in a way that the compiler can optimize away, is there really any need to create the atom at all in list_to_existing_atom/1? Therefore, it is better to place the responsibility that the atom exists on the user of list_to_existing_atom/1. Update the documentation to mention that the compiler may optimize away atoms. https://bugs.erlang.org/browse/ERL-453

2017-05-22Add enif_whereis_...() functionsTed Burghart
#### Why do we need this new feature? There are cases when a NIF needs to send a message, using `enif_send()`, to a long-lived process with a registered name. A common use-case is logging, where asynchronous fire-and-forget messages are the norm. There can also be cases where a yielding or dirty NIF or background thread may request a callback from a service with additional information it needs to complete its operation, yielding or waiting (with suitable timeouts, etc) until its state has been updated through the NIF module's API. NIFs can only send messages to pids, and the lack of name resolution leaves a complicated dance between separate monitoring processes and the NIF as the only way to keep a NIF informed of the whereabouts of such long-lived processes. Providing a reliable, built-in facility for NIFs to resolve process (or port) names simplifies these use cases considerably. #### Risks or uncertain artifacts? Testing has not exposed any significant risk. The implementation behaves as expected on regular and dirty scheduler threads as well as non-scheduler threads. By constraining the `enif_whereis_...()` functions to their minimal scopes and using patterns consistent with related functions, the implementation, testing, and maintenance burden is low. The API and behavior of existing functions is unchanged. #### How did you solve it? While extending `enif_send()` to operate on a pid or an atom (as `erlang:send/2` does) was attractive, it would have entailed changing the type of its `to_pid` parameter and thereby breaking backward compatibility. The same consideration applies to `enif_port_command()`. That leaves a choice between 1, 2, or 3 new functions: 1. `enif_whereis()` 2. `enif_whereis_pid()` and `enif_whereis_port()` 3. All of the above. While option (1), directly mimicking the behavior of `erlang:whereis/1`, is appealing, it poses potential problems if `pid()` or `port()` are subsequently implemented as non-integral types that must be bound to an owning `ErlNifEnv` instance. Therefore, option (2) has been chosen to use `ErlNifPid`/`ErlNifPort` structures in the API to maintain proper term ownership semantics.
