2016-03-30gen_fsm_SUITE: Make abnormal1/1 stop failingBjörn Gustavsson
abnormal1/1 started failing sporadically when 22785cd1e21 changed using the messages_get/0 and using its own implementation: get_messages() -> receive Msg -> [Msg|get_messages()] after 1 -> [] end. In test_server:messages_get/0, there was "after 0" instead of "after 1" as in this version. We could change back to using "after 0", but it seems that the test case just happened to work before the change. Instead, read out the message that is guranteed to be in the message queue, and *then* check that the message queue is empty.
2016-03-30gen_fsm_SUITE: Use timer:sleep/1 instead of ct:sleep/1Björn Gustavsson
In 8d7d5627, test_server:sleep/1 was changed to ct:sleep/1. Change it to timer:sleep/1 to make the timing more exact (ct:sleep/1 will call another process).

2016-03-09Replace "%" with "%%" at the beginning of a lineBjörn Gustavsson
We want to re-ident the source files after having taken out all ?line macros. When re-indenting using Emacs, it's important that comments that should be at the beginning of a line (or follow the indentation of statements around it) must start with "%%".

2016-03-09Replace calls to test_server:sleep/1 with ct:sleep/1 or timer:sleep/1Björn Gustavsson
Note that the sleeping time in ct:sleep/1 will be scaled if the test is run with (for example) cover. When it is important that the sleep time is not adjusted, use timer:sleep/1.

* siri/test-ct_release_test/OTP-13390: Remove upgrade tests from stdlib_SUITE Add test of ct_release_test
2016-03-09Remove upgrade tests from stdlib_SUITESiri Hansen
The test cases minor_upgrade and major_upgrade used ct_release_test. The point of the tests in stdlib was mainly to test ct_release_test. ct_release_test produces a 'from-release' based on an old version of the application under test (in this case stdlib) and new versions of all other applications. But since it is not always a good idea to load an old version of stdlib into a new emulator (e.g. in the OTP-19.0 emulator), these tests are removed. Instead new tests are added for ct_release_test in common_test.

2016-03-07io_SUITE: Don't fail on fast computers with rough timersBjörn Gustavsson
On a computer which is fast, but with timers with low resolution, the measured time for an empty queue could be zero, which could cause the test case to fail. Add a calibration function to scale up the amount the amount of work so that the measured time will not be lower than 50 ms.

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.
2016-02-17stdlib: Let the linter detect old typed recordsHans Bolinder
2016-02-17stdlib: Update module shell to handle typed record fieldsHans Bolinder
2016-02-17stdlib: Update ms_transform to handle typed record fieldsHans Bolinder
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.
2016-02-17Makefiles: Remove test_server from include path and code pathBjörn Gustavsson
Since no test suites includede test_server.hrl, there is no need to have test_server in the include path or code path.
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.

The two bad record usage test cases in compile_SUITE do not belong there, as the errors are detected in erl_lint. Move the test to the erl_lint_SUITE.
2016-02-03Speed up supervisor:count_children/1; simple_one_for_oneRory Byrne
Speed up supervisor:count_children/1 for simple_one_for_one supervisors. This is achieved by avoiding looping through all the child process and verifying that each one is alive. For a supervisor with 100,000 'temporary' children the count-time will drop from approx 25ms to about 0.005ms. For a supervisor with 100,000 'permanent' or 'transient' children the count-time will drop from approx 30ms to about 0.005ms. This avoids having the supervisor block for an extended period while the count takes place. Under normal circumstances the accuracy of the result should also improve since the duration is too short for many processes to die during the count.

2016-01-26Fix a race bug affecting dets_SUITE:open_file/2Hans Bolinder
The Dets server pretends the file is open before internal_open() has been called, which means that unless the internal_open message is applied first, other processes can find the pid by calling dets_server:get_pid() and do things before Head has been initialized properly.
2016-01-20Introduce time warp safe replacement for safe_fixed optionRickard Green
The new time warp safe option is safe_fixed_monotonic_time which gives erlang:monotonic_time(). The safe_fixed option was also slightly changed. It now gives erlang:timestamp() instead of erlang:now(). This has however not been documented, so it is considered a compatible change. The above effects both ets, and dets. This commit also include the bugfix OTP-13239 for dets:info(Tab, safe_fixed). The timestamp in the result returned by dets:info(Tab, safe_fixed) was unintentionally broken as a result of the time API rewrites in OTP 18.0.
