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.

2016-02-08Eliminate 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: Add a Cover testHans Bolinder
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.

2016-01-29Fix noproc crash during release installationRichard Jones
When release_handler_1:get_supervised_procs/0 does a recursive walk of the supervision tree, it calls sys:get_status/1 on supervisors, to check if they are suspended or running. This fixes a race condition where a list of supervisor pids is gathered, one of them (legitimately) exits before release_handler can examine it, then sys:get_status/1 is called with a dead pid, causing an exit(noproc) See: http://erlang.org/pipermail/erlang-questions/2015-August/085712.html (To recreate this problem for testing, I added a timer:sleep into the release_handler_1 code, and killed a supervisor during get_supervised_procs being called).

2016-01-28Ensure testing ssl with supported ciphers onlyDániel Szoboszlay
There are two problematic areas: EC curve selection and interoperability tests with OpenSSL. The tests shouldn't assume any particular EC curve is available, but should always check the list of curves reported by tls_v1:ecc_curves/1. And during interoperability tests the tests shouldn't assume that any cipher suite supported by Erlang is also supported by OpenSSL. There are OpenSSL packages where the command line openssl tool only supports a subset of the ciphers available in libcrypto. The actual list of supported cipher suites thus shall be queried from OpenSSL.
2016-01-28Only use supported EC curves in crypto testsDániel Szoboszlay
Avoid hardcoding EC curve names in tests where it basically doesn't matter which curve is used. Take one of the supported curbes instead. Also, when testing ECDH key generation, skip unsupported curves. These changes are to simplify dealing with exotic libcrypto builds that don't support certain curves (for example RHEL disallows < 256 bit curves). The crypto application is only able to detect the supported curves on a very coarse level (ECC support in general and GF2m curves), so it may be necessary to edit the list of curves in the crypto_ec_curves modules. But that should be the only necessary modification to make the crypto tests pass.

2016-01-28Use file read buffering in dbg:trace_clientPéter Gömöri
Trace files are typically large but contain small terms so we can expect a performance gain from read buffering. dbg:trace_client with a dummy handler ran more then 3x faster on a sample 200MB trace file. fprof:profile can also gain a bit.
