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.

2018-09-12[logger] Remove encoding option from logger_formatterSiri Hansen
The encoding option was introduced in commit 270d909696a753af022df72a404c73f2895b4a02, to allow report callbacks to format according to a given encoding. There was, however, no connection between this encoding option, and the encoding of the device to which the logger handler was writing. Since a formatter is defined to return unicode:chardata(), and in order to avoid mismatch with the encoding of the device, the encoding option is now removed from the formatter. The handler itself must make sure that it does not write illegal data to its device.

* maint: Correct error behavior of is_map_key/2 in guards
2018-08-13Correct error behavior of is_map_key/2 in guardsBjörn Gustavsson
Consider the following functions: foo() -> bar(not_a_map). bar(M) when not is_map_key(a, M) -> ok; bar(_) -> error. What will `foo/0` return? It depends. If the module is compiled with the default compiler options, the return value will be `ok`. If the module is compiled with the `inline` option, the return value will be `error`. The correct value is `error`, because the call to `is_map_key/2` when the second argument is not a map should fail the entire guard. That is the way other failing guards BIFs are handled. For example: foo() -> bar(not_a_tuple). bar(T) when not element(1, T) -> ok; bar(_) -> error. `foo/0` always returns `error` (whether the code is inlined or not). This bug can be fixed by changing the classification of `is_map_key/2` in the `erl_internal` module. It is now classified as a type test, which is incorrect because type tests should not fail. Reclassifying it as a plain guard BIF corrects the bug. This correction also fixes the internal consistency check failure which was reported in: https://bugs.erlang.org/browse/ERL-699

This only touches functions that are not further manually enhanced in erl_bif_types. The hope is that this will allow dialyzer to discover more issues in code using maps.
2018-07-19Optimise functions in the maps moduleMichał Muskała
Using direct pattern matching on the map is more effient than pattern matching on the result of maps:find/2, because it avoids allocating the intermediate tuple.
2018-07-17maps:new/0 is no longer a BIFMichał Muskała
Implementing it in Erlang allows taking advantage of the literal pool optimisation, this means the function implemented in Erlang does no allocations, while the BIF had to allocate new map each time it was called. Benchmarks show the function is also slightly faster now.
