2018-05-09epp: Implement the -if and -elif preprocessor directivesBjörn Gustavsson
Libraries or applications that support more than one major release of OTP may need to use conditional compilation of Erlang source code. Here are few examples where it would be necessary or desirable: * To support a new data type or language feature only available in the latest major release (real-world examples: maps and the stacktrace syntax). * To avoid warnings for deprecated functions. * To avoid dialyzer warnings. Previously, to do conditional compilation, one would have to use a parse transform or some external tool such as 'autoconf'. To simplify conditional compilation, introduce the -if and -elif preprocessor directives, to allow code like this to be written: -if(?OTP_RELEASE =:= 21). %% Code that will only work in OTP 21. -else. %% Fallback code. -endif. What kind of expressions should be allowed after an -if? We certainly don't want to allow anything with a side effect, such as a '!' or a 'receive'. We also don't want it to be possible to call erlang:system_info/1, as that could make the code depedent on features of the run-time system that could change very easily (such as the number of schedulers). Requiring the expression to be a guard expression makes most sense. It is to explain in the documentation and easy for users to understand. For simplicity of implementation, only a single guard expression will be supported; that is, the ',' and ';' syntax for guards is not supported. To allow some useful conditions to be written, there is a special built-in function: defined(Symbol) tests whether the preprocessor symbol is defined, just like -ifdef. The reason for having this defined/1 is that the defined test can be combined with other tests, for example: 'defined(SOME_NAME) andalso ?OTP_RELEASE > 21'.
2018-05-08erts: Make atomic ets:delete_all_objects yieldSverker Eriksson
by using a cooperative strategy that will make any process accessing the table execute delelete_all_objects_continue until the table is empty. This is not an optimal solution as concurrent threads will still block on the table lock, but at least thread progress is made.

2018-05-06epp: Add the pre-defined macro OTP_RELEASEBjörn Gustavsson
Add a new pre-defined macro called OTP_RELEASE that will expand to an integer being the OTP version. Thus, in OTP 19 the value will be the integer 19. The OTP_RELEASE macro is particularly useful in order to have different source code depending on new language features or new features in the type specification syntax. Those features are only introduced in major versions of OTP. To be truly useful, the -if preprocessor directive need to be implemented. That is the purpose of the next commit. Code that will need to work in both OTP 18 and OTP 19 can be structured in the following way: -ifdef(OTP_RELEASE). %% Code that only works in OTP 19 and later. -else. %% Code that will work in OTP 18. -endif.

2018-04-29Introduce is_map_key/2 guard BIFMichał Muskała
This complements the `map_get/2` guard BIF introduced in #1784. Rationale. `map_get/2` allows accessing map fields in guards, but it might be problematic in more complex guard expressions, for example: foo(X) when map_get(a, X) =:= 1 or is_list(X) -> ... The `is_list/1` part of the guard could never succeed since the `map_get/2` guard would fail the whole guard expression. In this situation, this could be solved by using `;` instead of `or` to separate the guards, but it is not possible in every case. To solve this situation, this PR proposes a `is_map_key/2` guard that allows to check if a map has key inside a guard before trying to access that key. When combined with `is_map/1` this allows to construct a purely boolean guard expression testing a value of a key in a map. Implementation. Given the use case motivating the introduction of this function, the PR contains compiler optimisations that produce optimial code for the following guard expression: foo(X) when is_map(X) and is_map_key(a, X) and map_get(a, X) =:= 1 -> ok; foo(_) -> error. Given all three tests share the failure label, the `is_map_key/2` and `is_map/2` tests are optimised away. As with `map_get/2` the `is_map_key/2` BIF is allowed in match specs.

Allow installing multiple instances of sys debug function This commit solves a bug which allowed installing {Fun,State} as sys debug function even if Fun was already installed. This happened in the case when the current State of the debug fun was undefined. Also, the new format {Id,Fun,State} of debug functions can be installed, allowing multiple instances of the same fun.

2018-04-25stdlib: Modify the printing of map associations with wWpPHans Bolinder
Use the same depth for all (printed) elements of a map. Since the order of keys can vary when printing a map--maps:iterator/1 and maps:next/1 are used--it is more consistent to print all associations with the same depth. If the associations printed are limited by the depth, the selection of associations is arbitrary, as before.
2018-04-25stdlib: Introduce characters limit of formated stringsHans Bolinder
Inspiration from module lager_format. Also some improvements of Unicode handling. io_lib:format/3 and io_lib:fwrite/3 are new functions. The representation of the options is a list, but we are considering using a map instead. If we change, it will happen after Erlang/OTP 21.0-rc1 is released.
2018-04-25stdlib: Modify ~w/~W when number of characters is limitedHans Bolinder
A bug fix: limited maps end with "...", not "...=>...". A modification: wW separate pairs with " => ", not "=>". When the output is limited on number of characters, the term is balanced by wW the same way as is done with pP (see commit bc38638).
