2016-04-25crypto: Deprecate rand_bytes/1Ingela Anderton Andin
OpenSSL has deprecated the function RAND_pseudo_bytes used by crypto:rand_bytes/1, so this function is now deprecated in OTP too. rand_bytes/3 also used this function, but was not documented so we can remove it right away. This commit also removes the fallback in generate_key to use rand_bytes/1 if strong_rand_bytes/1 throws low entropy. This is a potential incompatibility but we think it is desirable as crypto should provide cryptographically secure functions.
2016-04-21Modify code_change/4 to return CallbackModeRaimo Niskanen
Also move check of non-atom states in callback mode state_functions to where the state function is called. This gives homogenous diagnostics for state functions, code_change/4 and system_replace_state StateFun. Irregularities pointed out by James Fish.

2016-03-01Generalize bit string comprehensionsBjörn Gustavsson
The expression in a bit string comprehension is limited to a literal bit string expression. That is, the following code is legal: << <<X>> || X <- List >> but not this code: << foo(X) || X <- List >> The limitation is annoying. For one thing, tools that transform the abstract format must be careful not to produce code such as: << begin %% Some instrumentation code. <<X>> end || X <- List >> One reason for the limitation could be that we'll get reduce/reduce conflicts if we try to allow an arbitrary expression in a bit string comprehension: binary_comprehension -> '<<' expr '||' lc_exprs '>>' : {bc,?anno('$1'),'$2','$4'}. Unfortunately, there does not seem to be an easy way to work around that problem. The best we can do is to allow 'expr_max' expressions (as in the binary syntax): binary_comprehension -> '<<' expr_max '||' lc_exprs '>>' : {bc,?anno('$1'),'$2','$4'}. That will work, but functions calls must be enclosed in parentheses: << (foo(X)) || X <- List >>

2016-02-29Remove the remove_event action and all alikeRaimo Niskanen
Removing events from the internal queues is not necessary with the choosen semantics of the event queue vs. hibernate. In an early implementation it was possible by combining hibernate with e.g. postpone to get an event in the queue that you would not see before processing the postponed event, and therefore should you decide to cancel a timer it was essential to be able to remove that unseen event from the queue. With the choosen semantics you will have to postpone or generate an event for it to be in the event queue, and if you e.g. postpone a timeout event and then cancel the timer it is your mistake. You have seen the event and should know better than to try to cancel the timer. So, the actions: remove_event, cancel_timer, demonitor and unlink are now removed. There have also been some cleanup of the timer handling code.

2016-02-19stdlib: Let beam_lib restore typed record formsHans Bolinder
Forms with record field types created before OTP 19.0 are replaced by well-formed record forms holding the type information. Tools reading the 'abstract_code' chunk can rely on the returned forms being well-formed, that is, there are no badly formed 'type' attribute forms.
