2016-02-16erts: Add BIF erts_internal:system_check/1Björn-Egil Dahlberg
This commit implements erts_internal:system_check(schedulers) with the intent of a basic responsiveness test check of the schedulers.
2016-02-16kernel: Add validation callback for heartBjörn-Egil Dahlberg
* heart:set_callback/2 * heart:get_callback/0 * heart:clear_callback/0 The callback is called before every heartbeat to the heart port. The callback needs to return 'ok' if the validation is correct.

2016-02-09mnesia: let loader check if tablelock is neededDan Gudmundsson
move_table_copy needs the lock that was set previously in del_table_copy. This doesn't work on old nodes, so bump protocol version and check it. Remove old protocol conversion code, which have been around since OTP-R15. Checking if lock is needed requires rpc communication via mnesia_gvar ets table to be backwards compatible.
2016-02-09dialyzer: Correct byte_size() and comparisonsHans Bolinder
The argument of byte_size() is a bitstring(). The code in erl_bif_types that finds cases where comparisons always return true or false is corrected when it comes to maps and bit strings.

[James Fish:] Dialyzer always asserts that files and directories passed in its options exist. Therefore it is not possible to remove a beam/module from a PLT when the beam file no longer exists. Dialyzer should not to check files exist on disk when removing from the PLT.

2016-02-08Eliminate crash because of unsafe delaying of sub-binary creationBjörn Gustavsson
The following code would fail to compile: decode(<<Code/integer, Bin/binary>>) -> <<C1/integer, B1/binary>> = Bin, case C1 of X when X =:= 1 orelse X =:= 2 -> Bin2 = <<>>; _ -> Bin2 = B1 end, case Code of 1 -> decode(Bin2); _ -> Bin2 end. The error message would be: t: function decode/1+28: Internal consistency check failed - please report this bug. Instruction: return Error: {match_context,{x,0}}: The beam_bsm pass would delay the creation of a sub-binary when it was unsafe to do so. The culprit was the btb_follow_branch/3 function that for performance reasons cached labels that had already been checked. The problem was the safety of a label also depends on the contents of the registers. Therefore, the key for caching needs to be both the label and the register contents. Reported-by: José Valim

2016-02-05mnesia: Avoid deadlock possibility in mnesia:del_table_copy schemaDan Gudmundsson
del_table_copy grabs a write lock in a new process in prepare_op/3 to change 'where_to_read' when a table copy is updated. When del_table_copy(schema, Node) is called all copies located on Node are deleted, and thus many locks are taken. Since this was done outside of the schema-transaction, mnesia's deadlock prevention algorithms was sidestepped and a deadlock could occur. Fix by always grabbing write-locks for all changed tabs early and in the same transaction, this might slow done the operation some but it must be done and it also cleans up the code.

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.
2016-02-03Add supervisor:get_callback_module/1Siri Hansen
This function is used by release_handler during upgrade. This was earlier implemented in the release_handler, but it required a copy og the definition of the supervisor's internal state, which caused problems when this state was updated.

2016-02-03tools: Fix wrong instrumentation of binary comprehensionsLuis Rascao
When cover instruments binary comprehensions it's generating a {block, ...} abstract code term inside a {bc, ...} term that is causing the evaluation to fail at runtime. Removing the block statement eliminates the error. The template of a bit string comprehension cannot have a counter since it is not allowed to be a block.
