2015-12-16erl_prim_loader doc: Remove mention of user supplied loaderBjörn Gustavsson
Custom loaders are no longer supported. Most of the documentation for them were removed in c8a7d2d7.
2015-12-16Clean up start of erl_prim_loaderBjörn Gustavsson
The 'init' module fetches command line parameters and passes them to erl_prim_loader:start/3. The code can be simplified if 'init' calls a new erl_prim_loader:start/0 function that itself fetches the necessary command line parameters. Also remove the documentation for the start() function, since it there is no way that it can be usefully called by a user application. While we are at it, also get rid of '-id' command line parameter, which is fetched and stored but never actually used.

2015-11-12Fragmented young heap generation and off_heap_message_queue optionRickard Green
* The youngest generation of the heap can now consist of multiple blocks. Heap fragments and message fragments are added to the youngest generation when needed without triggering a GC. After a GC the youngest generation is contained in one single block. * The off_heap_message_queue process flag has been added. When enabled all message data in the queue is kept off heap. When a message is selected from the queue, the message fragment (or heap fragment) containing the actual message is attached to the youngest generation. Messages stored off heap is not part of GC.

2015-10-08Take out automatic insertion of 'undefined' from typed record fieldsKostis Sagonas
Background ----------- In record fields with a type declaration but without an initializer, the Erlang parser inserted automatically the singleton type 'undefined' to the list of declared types, if that value was not present there. I.e. the record declaration: -record(rec, {f1 :: float(), f2 = 42 :: integer(), f3 :: some_mod:some_typ()}). was translated by the parser to: -record(rec, {f1 :: float() | 'undefined', f2 = 42 :: integer(), f3 :: some_mod:some_typ() | 'undefined'}). The rationale for this was that creation of a "dummy" #rec{} record should not result in a warning from dialyzer that e.g. the implicit initialization of the #rec.f1 field violates its type declaration. Problems --------- This seemingly innocent action has some unforeseen consequences. For starters, there is no way for programmers to declare that e.g. only floats make sense for the f1 field of #rec{} records when there is no `obvious' default initializer for this field. (This also affects tools like PropEr that use these declarations produced by the Erlang parser to generate random instances of records for testing purposes.) It also means that dialyzer does not warn if e.g. an is_atom/1 test or something more exotic like an atom_to_list/1 call is performed on the value of the f1 field. Similarly, there is no way to extend dialyzer to warn if it finds record constructions where f1 is not initialized to some float. Last but not least, it is semantically problematic when the type of the field is an opaque type: creating a union of an opaque and a structured type is very problematic for analysis because it fundamentally breaks the opacity of the term at that point. Change ------- To solve these problems the parser will not automatically insert the 'undefined' value anymore; instead the user has the option to choose the places where this value makes sense (for the field) and where it does not and insert the | 'undefined' there manually. Consequences of this change ---------------------------- This change means that dialyzer will issue a warning for all places where records with uninitialized fields are created and those fields have a declared type that is incompatible with 'undefined' (e.g. float()). This warning can be suppressed easily by adding | 'undefined' to the type of this field. This also adds documentation that the user really intends to create records where this field is uninitialized.
