2014-03-26ose: Prepare slave for running on OSELukas Larsson
This change relies on the assumption that all arguments before the last -- to the parent beam should be left as they are.
2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
The inet driver for OSE has to handle signals instead of selects and thus the wrappers for ready_input/output are a little bit different. However the majority of the inet code remains the same.

2014-03-20Verify runtime_dependencies when running 'otp_build patch_app'Rickard Green
2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.

2014-03-10Correct file:set_cwd/1 typespecJosé Valim
file:set_cwd/1 accepts binaries as arguments, however the binaries must be properly encoded as per file:native_name_encoding/0. Also update the note under no_translation error to refer that passing a ISO-latin-1 encoded binary under any unicode file name encoding.
2014-03-07Support the LLVM backend in HiPEYiannis Tsiouris
Add flags to enable and use the LLVM backend: * to_llvm: use the LLVM pipeline for compilation (default optimization level is O3), * llvm_save_temps: save the intermediate files in current directory in order to be able to debug or optimize the LLVM assembly, * {to_llvm, O}: set the optimization level of LLVM opt and llc tools. Add some debug support to the loader; no semantic change intented.
2014-02-28prim_file_SUITE: Remove the short 5 seconds timetrap timeoutBjörn Gustavsson
Several tests cases would typically fail because of a timetrap timeout on our older test machines running with a Linux kernel with a lower version than 2.6.30 and the ext3 file system. In http://lwn.net/Articles/328363/, the author desribes peformance issues with ext3 that were fixed in 2.6.30. Since common_test nowadays has a default timetrap timeout, there is no need to explicitly set a timeout in each test case (except for prolonging the default timeout).
2014-02-28Delay patching of closures to eliminate a race conditionBjörn Gustavsson
The loader of native code tries to avoid race condition by bringing down the system to a single scheduler. Unfortunately, that will not completely avoid race conditions beacuse other processes may still run while the code is being loaded. Therefore, we must still make sure that native code has been fully fixed up before it can be executed. Under unlucky circumstances, it was possible for the global name register process to call a fun in native code before the native code for the fun had been fully fixed up. The run-time system would crash when running the not-fully-fixed-up code. Here is a way to make the bug 100% reproducible. First add this function to the 'global' module: silly_looper(List) -> lists:foreach(fun(E) -> put(any_atom, E) end, List), silly_looper(List). Then insert the following code at the beginning of the init/1 function in the 'global' module: spawn_link(fun() -> silly_looper(lists:seq(1, 100)) end), The run-time system will crash during start up when the native code for the 'global' module is being loaded. What will happen is that lists:foreach/2 (which runs in native code) will call the native code for the fun in silly_looper/1 before the reference to 'any_atom' has been changed from a 0 to the proper tagged atom value. The put/2 BIF will exit when attempting to calculate the hash value for the illegal value 0 (it is not properly tagged). To eliminate this race condition, we must delay patching the native code addresses for a fun into the fun entry until the native code has been fully fixed up. We will use the new BIFs introduced in the previous commit. While we are at it, we will also make sure that we erase any temporary variables in the process dictionary used by the hipe_unified_loader module.
2014-02-28hipe: Break apart hipe_bif:make_fe/3 into two BIFsBjörn Gustavsson
This commit is a preparation for eliminating a race condition loading the native code for modules whose BEAM code has already been loaded. Here we introduce two new BIFs so that looking up a fun entry is separate from setting the native address in the fun entry.

* siri/master-cuddle-with-tests: Use default timetrap (30 min) for kernel, stdlib and sasl app tests Unload 'deadlock' application in application_SUITE:shutdown_deadlock
2014-02-23Deprecate pre-defined built-in typesHans Bolinder
The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(), set(), and tid() have been deprecated. They will be removed in OTP 18.0. Instead the types array:array(), dict:dict(), digraph:graph(), gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid() can be used. (Note: it has always been necessary to use ets:tid().) It is allowed in OTP 17.0 to locally re-define the types array(), dict(), and so on. New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2, queue:queue/1, and sets:set/1 have been added.
2014-02-21Use default timetrap (30 min) for kernel, stdlib and sasl app testsSiri Hansen
These tests start new nodes, and they frequently timed out on some slow test hosts.
2014-02-21Unload 'deadlock' application in application_SUITE:shutdown_deadlockSiri Hansen
This is just to clean up properly after the test case. If not, code_SUITE:bit_boot_embedded might fail since it tries to include the 'deadlock' application in the boot file and fails when running systools:make_script.

Could happen if get_child was called during terminate. io (since it is a group_leader) also causes problems after get_child was called. Split up and do it async.

2014-02-12Fix a few of Dialyzer's unmatched_return warningsHans Bolinder
2014-02-12Update appups and appup tests for kernel, stdlib and saslSiri Hansen
Appups now only support one major release back, and the tests are updated accordingly. Support is also added in tests for giving previous releases in a ct config file, e.g. {otp_releases,[{r15,"/path/to/r15/bin/erl"}, {r16,"/path/to/r16/bin/erl"}, {'17',"/path/to/17/bin/erl"}]}.
2014-02-11Allow persistent option on set_env/4 and unset_env/3José Valim
An environment key set with the persistent option will not be overridden by the ones configured in the application resource file on load. This means persistent values will stick after the application is loaded and also on application reload.
