* legoscia/erts/epmd-module-option/OTP-13627: Add tests for -start_epmd and -epmd_module options Use the -epmd_module flag consistently Add -start_epmd command line option

2016-05-25Add tests for -start_epmd and -epmd_module optionsMagnus Henoch
For -start_epmd, check that the node starts properly and that we can ping it. For -epmd_module, start two nodes that can communicate only because we supply the correct port number through a command line argument.
2016-05-25Use the -epmd_module flag consistentlyMagnus Henoch
If the -epmd_module flag has been specified on the command line, use that module to register and look up node names instead of the default, erl_epmd. Also document this option.
2016-05-25Add -start_epmd command line optionMagnus Henoch
Add a command line option that lets you disable automatic starting of epmd when starting a distributed node. This differs from the undocumented setting -no_epmd, in that it does not affect the starting of an erl_epmd process within erl_distribution: the newly started node will expect an epmd instance to have been started previously.

2016-05-24erts: Move tracer SecondTraceTerm to Opts mapLukas Larsson
The extra trace data has been moved to the opts map in order for the tracer to be able to distinguish inbetween extra trace data 'undefined' and no extra trace data. In the same commit all opts associations have been changed so that if the tracer should not use them, the key is left unassicated instead of being sent to undefined. This should be give a small performance gain and also makes the API easier to work with.

2016-05-20erts: Copy literals in messages on module purgeBjörn-Egil Dahlberg
During check process code, explicitly copy all referenced literals in a message (in the private queue) to a heap fragment and attach it to the message reference. Not all types of message communication does an explicit copy of a literal and this needs to be taken care of before a module is purged.

Specifically t_copy_literals_frags/1 tries to test literals in message heap fragments.

2016-05-17erts: Fix OpenBSD gcc compiler bug in re codeLukas Larsson
The OpenBSD 5.8 gcc compiler emits erroneous code which results in the re:run function behaving badly, though strangely enough it does not segfault the vm. This fix moves code around a bit in order to make gcc emit correct code.

2016-05-16Tolerate bad directories in the code pathBjörn Gustavsson
A bad directory in the path would prevent the run-time system from starting: $ echo >foobar $ erl -pa foobar {"init terminating in do_boot",{load_failed,[supervisor,kernel,gen_server,file_io_server,filename,file,erl_parse,error_logger,code_server,erl_lint,proc_lib,code,application_controller,application_master,gen_event,application,error_handler,lists,heart,gen,file_server,ets,erl_eval]}} Crash dump is being written to: erl_crash.dump...done init terminating in do_boot () The reason is that when attempting to read each of the BEAM files, there would be an 'enotdir' error which erl_prim_load:get_modules/2,3 assumed was a fatal error. Update erl_prim_load:get_modules/2,3 to ignore any error and try the next directory in the path. Reported-by: http://bugs.erlang.org/browse/ERL-142 Reported-by: Michael Truog
2016-05-16Remove the warning about using erlang:raise/3Björn Gustavsson
There is no good reason to say that erlang:raise/3 is only for debugging. Here is an example where it can be extremely useful: try do_something(Args) catch Class:Error -> Stack = erlang:get_stacktrace(), io:format("Args: ~p\n", [Args]), erlang:raise(Class, Error, Stack) That is, we can let it crash, but log additional useful information before crashing.

2016-05-12time_SUITE: Make consistency/1 work in any timezoneBjörn Gustavsson
time_SUITE:consistency/1 would only work in CET, which was reasonable when the test suites were always run in Stockholm. Nowadays it is expected that you can run the test suite in any timezone. Therefore, only make sure that that difference between localtime/1 and universaltime/1 is "reasonable".

2016-05-11erts: Only allow remove from trace_status callbackLukas Larsson
Make it so that it is only possible to remove a tracer via returning remove from an erl_tracer. This limition is put in place in order to avoid a lot of lock checking and taking in various places, especially in regards to trace events happening on dirty schedulers.

2016-05-11hipe_llvm: Allow LLVM-generated constantsMagnus Lång
Since 3.7, LLVM sometimes generates SSE constants in a special constant section with the requisite alignment (".rodata.cst16"). This broke hipe_llvm since it assumed that all constants that were linked from the text section were constants generated by hipe_llvm. As this is the first time alignments larger than 8 have been required, some small changes were required to hipe_consttab and hipe_bifs:alloc_data/2. Note that hipe_bifs:alloc_data/2 still assumes that erl_alloc will provide the requisite alignment.
