2016-02-11erl_prim_loader_SUITE: Refactor helper functionsBjörn Gustavsson
Eliminate duplicated code by factoring out the common code for starting erl_boot_server and a slave node. Also, in the new start_boot_server/0 helper, fix a problem with Linux systems that assign 127.0.1.1 as the IP address for the hostname. Also stop using the -setcookie option when starting a node using -loader inet. The inet loading method doesn't use the distribution anymore.

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

2016-02-05Move record compilation errors to erl_lint_SUITEBjörn Gustavsson
The two bad record usage test cases in compile_SUITE do not belong there, as the errors are detected in erl_lint. Move the test to the erl_lint_SUITE.
2016-02-05compile_SUITE: Use get_files/3 in more placesBjörn Gustavsson
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.
2016-02-05compile_SUITE: Replace confusing files/2 with get_files/3Björn Gustavsson
The files/2 function is confusing. The second argument names the output directory, not the name of the source module. It is common trap to attempt to point a different source file using files/2. Introduce the new get_files/3 which explicitly names the module name.

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.
2016-02-03v3_core: Eliminate double processing of patternsBjörn Gustavsson
Internally in the v3_core pass, an #imatch{} record represents a match expression: Pattern = Expression If Pattern is a single, unbound variable, #imatch{} will be rewritten to #iset{}; otherwise it will be rewritten to #icase{}. To determine how #imatch{} should be translated, the pattern is processed using upattern/3. The return value from upattern/3 is thrown away (after having been used for determing how the #imatch{} record should be translated). That means that every pattern in an #imatch{} is processed twice, which is wasteful. We can easily avoid the double processing of patterns by introducing a new helper function that determines whether the pattern is a new variable.
