2016-03-10beam_block: Eliminate unsafe optimizationBjörn Gustavsson
Consider this code: %% Start of block get_tuple_element Tuple 0 Element get_map_elements Fail Map [Key => Dest] . . . move Element UltimateDest %% End of block Fail: %% Code that uses Element. beam_block (more precisely, otp_tuple_element/1) would incorrectly transform the code to this: %% Start of block get_map_elements Fail Map [Key => Dest] . . . get_tuple_element Tuple 0 UltimateDest %% End of block Fail: %% Code that uses Element. That is, the code at label Fail would use register Element, which is either uninitalized or contains the wrong value. We could fix this problem by always keeping label information at hand when optimizing blocks so that we could check the code at the failure label for get_map_elements. That would require changes to beam_block and beam_utils. We might consider doing that in the future if it turns out be worth it. For now, I have decided that I want to keep the simplicity of blocks (allowing them to be optimized without keeping label information). That could be achieved by not including get_map_elements in blocks. Another way, which I have chosen, is to only allow get_map_elements as the first instruction in the block. For background on the bug: c288ab8 introduced the beam_reorder pass and 5f431276 introduced opt_tuple_element() in beam_block.

2016-03-09erts: Fix wobbling tests in nif_SUITESverker Eriksson
No point in checking tmp_alloc instance 0 as any non-scheduler thread could race us.

2016-03-09Remove ?line macrosBjörn Gustavsson
While we are it, also re-ident the files.
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 "%%".

The return values for lists:prefix/2 and lists:member/2 were ignored.
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.
2016-03-09Eliminate use of test_server:do_times()Björn Gustavsson
2016-03-09Replace use of test_server:format/2 with io:format/2Björn Gustavsson
There is no practial difference.

2016-03-09Modernize use of timetrapsBjörn Gustavsson
Either rely on the default 30 minutes timetrap, or set the timeout using the supported methods in common_test.

* 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.
2016-03-09Add test of ct_release_testSiri Hansen
The ct_release_test module provides support for testing upgrade/code_change of one or more applications within the Erlang/OTP product. This commit adds tests to the common_test/test directory.
