2016-02-17stdlib: Modify the preprocessor as to expose typed record fieldsHans Bolinder
Problem: The types of record fields have since R12B been put in a separate form by epp:parse_file(), leaving the record declaration form untyped. The separate form, however, does not follow the syntax of type declarations, and parse transforms inspecting -type() attributes need to know about the special syntax. Since the compiler stores the return value of epp:parse_file() as debug information in the abstract code chunk ("Abst" or 'abstract_code'), tools too need to know about the special syntax, if they inspect -type() attributes in abstract code. Solution: As of this commit no separate form is created by epp:parse_file(), but the type information kept in the record fields. This means that all parse transforms and all tools inspecting -record() declarations need to recognize {typed_record_field, Field, Type}. We recommend that all parse transforms and tools be updated as to recognize typed record fields. Discussion: As of OTP 19.0, the abstract form of type declarations and function specifications is documented. An (unsatisfactory) alternative to the above solution is to document two formats of the abstract form of typed record fields: one if returned by epp:parse_file(); and one if returned by, for example, epp:parse_erl_form(). Yet another (bad) alternative is to not document the format returned by epp:erl_parse(), but instead document the idempotent function epp:restore_typed_record_fields/1, and urge authors of parse transform and tools to always call this function.

2016-02-15Add dirty scheduler process termination testSteve Vinoski
In scheduler_SUITE add a new test that runs a single dirty I/O scheduler and launches a number of dirty I/O NIF calls that each sleep for 3 seconds. Given the single scheduler, the first of these will run while the rest queue up. Then start killing these processes, and verify they call exit correctly.
2016-02-15Ensure that work is done on the correct type of schedulersRickard Green
Only the actual call to the dirty nif is allowed to execute on dirty schedulers. The dirty nif is not allowed to execute on normal schedulers if dirty schedulers are available. Arrival of exit signals and system tasks, while a process was scheduled for execution on a dirty scheduler, could mess up the process internal state. Preparation for dirty system task has been made, but is currently unused.

2016-02-11erl_prim_loader_SUITE: Refactor helper functionsBjörn Gustavsson
Eliminate duplicated code by factoring out the common code for starting erl_boot_server and a slave node. Also, in the new start_boot_server/0 helper, fix a problem with Linux systems that assign 127.0.1.1 as the IP address for the hostname. Also stop using the -setcookie option when starting a node using -loader inet. The inet loading method doesn't use the distribution anymore.

2016-02-09mnesia: let loader check if tablelock is neededDan Gudmundsson
move_table_copy needs the lock that was set previously in del_table_copy. This doesn't work on old nodes, so bump protocol version and check it. Remove old protocol conversion code, which have been around since OTP-R15. Checking if lock is needed requires rpc communication via mnesia_gvar ets table to be backwards compatible.
2016-02-09dialyzer: Correct byte_size() and comparisonsHans Bolinder
The argument of byte_size() is a bitstring(). The code in erl_bif_types that finds cases where comparisons always return true or false is corrected when it comes to maps and bit strings.
