2016-02-25Allow erlang:finish_loading/1 to load more than one moduleBjörn Gustavsson
The BIFs prepare_loading/2 and finish_loading/1 have been designed to allow fast loading in parallel of many modules. Because of the complications with on_load functions, the initial implementation of finish_loading/1 only allowed a single element in the list of prepared modules. finish_loading/1 does not suspend other processes, but it must wait for all schedulers to pass a write barrier ("thread progress"). The time for all schedulers to pass the write barrier is highly variable, depending on what kind of code they are executing. Therefore, allowing finish_loading/1 to finish the loading for more than one module before passing the write barrier could potentially be much faster than calling finish_loading/1 multiple times. The test case many/1 run on my computer shows that with "heavy load", finish loading of 100 modules in parallel is almost 50 times faster than loading them sequentially. With "light load", the gain is still almost 10 times. Here follows an actual sample of the output from the test case on my computer (an 2012 iMac): Light load ========== Sequential: 22361 µs Parallel: 2586 µs Ratio: 9 Heavy load ========== Sequential: 254512 µs Parallel: 5246 µs Ratio: 49

2016-02-19stdlib: Let beam_lib restore typed record formsHans Bolinder
Forms with record field types created before OTP 19.0 are replaced by well-formed record forms holding the type information. Tools reading the 'abstract_code' chunk can rely on the returned forms being well-formed, that is, there are no badly formed 'type' attribute forms.

2016-02-17Implement ?FUNCTION_NAME and ?FUNCTION_ARITY macrosBjörn Gustavsson
For a long time, users have asked for one or more macros that would return the name and arity of the current function. We could define a single ?FUNCTION macro that would return a {Name,Arity} tuple. However, to access just the name or just the arity for the function, element/2 must be used. That would limit its usefulness, because element/2 is not allowed in all contexts. Therefore, it seems that we will need two macros. ?FUNCTION_NAME that expands to the name of the current function and ?FUNCTION_ARITY that expands to arity of the current function. Converting the function name to a string can be done like this: f() -> atom_to_list(?FUNCTION_NAME) ++ "/" ++ integer_to_list(?FUNCTION_ARITY). f/0 will return "f/0". The BEAM compiler will evaluate the entire expression at compile-time, so there will not be any run-time penalty for the function calls. The implementation is non-trivial because the preprocessor is run before the parser. One way to implement the macros would be to replace them with some placeholder and then let the parser or possibly a later pass replace the placeholder with correct value. That could potentially slow down the compiler and cause incompatibilities for parse transforms. Another way is to let the preprocessor do the whole job. That means that the preprocessor will have to scan the function head to find out the name and arity. The scanning of the function head can be delayed until the first occurrence of a ?FUNCTION_NAME or ?FUNCTION_ARITY. I have chosen the second way because it seems less likely to cause weird compatibility problems.

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.
2016-02-17Remove test_server as a standalone applicationBjörn Gustavsson
The test_server application has previously been deprecated. In OTP 19, we will move relevant parts of test_server into the common_test application. Test suites that include test_server.hrl must be updated to include ct.hrl instead. Test suites that include test_server_line.hrl must removed that inclusion. Test suites that call the test_server module directly will continue to work in OTP 19. The test suites for Erlang/OTP are built and executed in exactly the same way as previously. Here are some more details. The modules test_server*.erl and erl2html2.erl in lib/test_server/src have been moved to common_test/src. The test_server.hrl and test_server_line.hrl include files have been deleted. The macros in test_server.hrl have been copied into lib/common_test/include/ct.hrl. The ts*.erl modules and their associated data files in lib/test_server/src has been been moved to the new directory lib/common_test/test_server. The ts* modules are no longer built to lib/common_test/ebin. They will only built when 'make release_tests' is executed. The test suite for test_server has been moved to lib/common_test/test. The rest of the files have been deleted.

2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.
