2016-03-10Improved scheduler suspend functionalityRickard Green
- The calling process is now suspended while synchronizing scheduler suspends via erlang:system_flag(schedulers_online, _) and erlang:system_flag(multi_scheduling, _), instead of blocking the scheduler thread in the BIF call waiting for the operation to synchronize. Besides releasing the scheduler for other work (or immediate suspend) it also makes it possible to abort the operation by killing the process. - erlang:system_flag(schedulers_online, _) now only wait for normal schedulers to complete before it returns. This since it may take a very long time before all dirty schedulers suspends. - erlang:system_flag(multi_scheduling, block_normal|unblock_normal) which only operate on normal schedulers has been introduced. This since there are use cases where suspend of dirty schedulers are not of interest (hipe loader). - erlang:system_flag(multi_scheduling, block) still blocks all dirty schedulers as well as all normal schedulers except one since it is hard to redefine what multi scheduling block means. - The three operations: - changing amount of schedulers online - blocking/unblocking normal multi scheduling - blocking/unblocking full multi scheduling can now be done in parallel. This is important since otherwise a full multi scheduling block would potentially delay the other operations for a very long time.
2016-03-10Remove ?line macrosBjörn Gustavsson
While we are it, also re-ident the files.
2016-03-10Fix commentsBjörn Gustavsson
Remove out-commented code. Make sure that comments that are not at the end of a line starts with two '%' characters and not just one. That will become important later when we'll remove all ?line macros and ask Emacs to re-indent the files.
2016-03-10gen_tcp_misc_SUITE: Use unique node namesBjörn Gustavsson
Use unique node names to ensure that one failed test case will not cause other test cases to fail if a slave node was left.

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.

?config is ugly and not recommended. Use proplists:get_value/2 instead.

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 "%%".

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.
