2016-05-04epp: Add the -error and -warning directivesBjörn Gustavsson
If one of several alternatives configurations are required for an Erlang module to compile, but none are available, it would be useful to give a nice error message. For example: -ifdef(CONFIG_A). %% Some code if A is true. -else. -ifdef(CONFIG_B). %% Some code if B is true. -else. -error("Neither CONFIG_A nor CONFIG_B are available"). -endif. -endif. If neither CONFIG_A nor CONFIG_B are defined, the error message will be: module.erl:10: -error("Neither CONFIG_A nor CONFIG_B are available"). That is basically the same behavior as for the #error directive in GCC. For symmetry with the -error directive, add the -warning directive to generate a compiler warning. For example: -ifdef(HAVE_COOL_FEATURE). %% Code if we have Cool Feature. -else. %% Inefficient fallback code. -warning("Using inefficient fallback"). -endif. If HAVE_COOL_FEATURE is not defined, the warning message will be: module.erl:8: Warning: -warning("Using inefficient fallback"). That is basically the same behavior as for the #warning directive in GCC. Conflicts: lib/stdlib/src/epp.erl lib/stdlib/test/epp_SUITE.erl
2016-05-04epp: Refactor expansion of header pathBjörn Gustavsson
scan_include_lib/4 uses a helper function find_lib_dir/1, which has a strange interface. It takes a string and returns a tuple. The caller must match the tuple and call fname_join/1 to obtain the desired result. I assume that the strange interface was not noticed because the function is only used in one place. Replace the find_lib_dir/1 with a new expand_lib_dir/1 function which does the entire job in one go. The new function is much easier to reuse in other places, which we might want to do in a future commit.

2016-05-02stdlib: Fix linting of map key variablesBjörn-Egil Dahlberg
Map keys cannot be bound and then used in parallel matching. Example: #{ K := V } = #{ k := K } = M. This is illegal if 'K' is not already bound.

2016-04-28stdlib: Add shadow comments for BIFs in mapsBjörn-Egil Dahlberg
Type information is stored in erl_bif_types for certain BIFs. This fact must be stated in the type specification for the stubs that are superceded by erl_bif_types. * Shadowed by erl_bif_types: maps:from_list/1 * Shadowed by erl_bif_types: maps:get/2 * Shadowed by erl_bif_types: maps:is_key/2 * Shadowed by erl_bif_types: maps:merge/2 * Shadowed by erl_bif_types: maps:put/3 * Shadowed by erl_bif_types: maps:to_list/1 * Shadowed by erl_bif_types: maps:update/3

2016-04-28Enhance map specs in erts, stdlib, runtime_toolsMagnus Lång
Using the new type syntax, we can specify which keys are required, and which are optional in a way Dialyzer could use.
2016-04-28erl_parse: Add parsing for new map type syntaxMagnus Lång
erl_types typesets mandatory keys with :=, and uses "..." as a shorthand for "any() => any()". Add these to erl_parse so that all representable types can be written in type-specs.

2016-04-25stdlib: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
The use case is not cryptographical but we want to compare Erlang implementation to c implementation so use crypto:strong_rand_bytes anyway.
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.

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.
