Fix remote-call error in ms_transform
2018-12-18Make all compiler options work in the option listBjörn Gustavsson
Before OTP 22, the option `{nowarn_deprecated_function,MFAs}` was only recognized when given in the file with the attribute `-compile()`. (The option `{nowarn_unused_function,FAs}` was incorrectly documented to only work in a file, but it also worked when given in the option list.) Starting from OTP 22, all options that can be given in the file can also be given in the option list.

2018-11-29stdlib: Let calendar:system_time_to_rfc3339() keep fractionsHans Bolinder
RFC3339 mentions in paragraph 5.1 that if certain conditions are fulfilled, then sorting date and time strings results in a time-ordered sequence. One of the conditions is that the strings must have the same number of fractional second digits. This commits makes sure this is indeed the case.

* maint: Fix inadvertently suppressed warning for unused variable
2018-11-21Fix inadvertently suppressed warning for unused variableBjörn Gustavsson
An external fun could inadvertently suppress warnings for unused variables, such as in this example: bug() -> BugVar = foo(), if true -> fun m:f/1 end. There would be no warning that `BugVar` was unused. The bug was introduced in ff432e262e652, which was the commit that extended external funs to allow variables. https://bugs.erlang.org/browse/ERL-762

Before this patch the following call resulted in the below error ``` 1> dbg:fun2ms(fun(_) -> m:f() end). Error: Unknown error code {122,m,f} ``` Now it is properly formatted as ``` 1> dbg:fun2ms(fun(_) -> m:f() end). Error: fun containing the remote function call 'm:f/0' (called in body) cannot be translated into match_spec ```

* maint: beam_lib: Remove obsolete module() from the beam() type hipe: Don't use beam_lib:info/1 with an atom as filename Honor the max heap size when copying literals after purging

2018-10-19beam_lib: Remove obsolete module() from the beam() typeBjörn Gustavsson
The type `beam()` in the `beam_lib` module is confusing: -type beam() :: module() | file:filename() | binary(). It says that the module name can be used to identify the BEAM module to be accessed, but passing in the module name only works if the BEAM file is located in the current working directory because the module is not searched for in the code path. The reason that it is allowed to pass in the module name as an atom is for backward compatibility. A long time ago, atoms instead of strings were used as filenames. For that reason, `filename` and `file` still accept atoms as filenames (although the practice is frown upon). `beam_lib` accepts an atom as the filename for the same reason. To remove the confusion, remove `module()` from the type and the mention of it in the documentation. Code that uses an atom as a filename will still work, but Dialyzer will issue a warning. https://bugs.erlang.org/browse/ERL-696

OTP-14731 Implement 'exsss' (Xorshift116**) as new default 'rand' algorithm The new algorithm is a combination of the Xorshift116 ('exsp') state update and a new scrambler "StarStar" from the 2018 paper "Scrambled Linear Pseudorandom Number Generators" by David Blackman and Sebastiano Vigna. This combination should not have the caveat of weak low bits that the previous default algorithm(s) have had, with the cost of about 10% lower speed.

2018-09-18Merge pull request #1857 from RaimoNiskanen/raimo/rand-crypto-xoroshiro928Raimo Niskanen
OTP-14461 - New 'rand' algorithm: Xoroshiro928** also for 'crypto' Implement a new 'rand' algorithm named 'exro928ss' and a new 'crypto' plugin for 'rand' named 'crypto_aes'. Both are based on Xoroshiro928** which is derived from Xoroshiro1024** modified to use 58-bit words for performance reasons in the Erlang VM. Xoroshiro1024** has got the Xoroshiro1024 generator and the StarStar scrambler from the 2018 paper "Scrambled Linear Pseudorandom Number Generators" by David Blackman and Sebastiano Vigna. This generator and scrambler combination shows no systematic weaknesses in standard statistical tests as TestU01(BigCrush) and PractRand, unlike the previously used * and + scramblers in the 'rand' module that exhibit statistical weaknesses for the lowest bits. The 'crypto' plugin uses AES-256 as scrambler and the Xoroshiro928 as generator, which gives the same very long period and jump functions as for Xoroshiro928**, but a cryptographically secure scrambler gives absolutely no detectable statistical weaknesses regardless of how the generated numbers are used. The speed of 'exro928ss' is only about 30-50% slower than the default fast 'rand' algorithm, but the state is roughly the double and it produces about 8 times the garbage per iteration. The speed of 'crypto_aes' is about half (amortized) that of the default fast 'rand' algorithm which is fast and thanks to doing encryption in batches caching the result. Hence the state is much larger.

* maint: stdlib: Allow lists with binaries in the Format argument
2018-09-17stdlib: Allow lists with binaries in the Format argumentHans Bolinder
As a consequence of some refactoring (OTP-14983, option 'chars_limit'), the Format argument of io_lib:format() no longer accepts binaries in lists in Erlang/OTP 21.0. Note that if Format is not of type io:format(), control sequences in Format are ignored. This can result in unpredictable behaviour if, for example, the output of io_lib:format() is used as Format: if the output happens to be a string(), then control sequences are interpreted, otherwise not. A check that Format is of type io:format() will likely be introduced in Erlang/OTP 22.0. That will probably mean work for some users, but considering how unpredictable io_lib:format() is, we should try to fix that.
