2016-04-28erl_bif_types: Add a selection of maps BIFsMagnus Lång

2016-04-28erl_types: Add a map type representationMagnus Lång
The type of a map is represented as a three-tuple {Pairs, DefaultKey, DefaultValue}. DefaultKey and DefaultValue are types. Pairs is a list of three-tuples {Key, mandatory | optional, Value}, where Key and Value are types. All types Key must be singleton, or "known at compile time," as the EEP put it. Examples: #{integer()=>list()} {[], integer(), list()} #{a=>char(), b=>atom()} {[{a, optional, char()}, {b, optional, atom()}], none(), none()} map() {[], any(), any()} A more formal description of the representation and its invariants can be found in erl_types.erl Special thanks to Daniel S. McCain (@dsmccain) that co-authored a very early version of this with me back in April 2014, although only the singleton type logic remains from that version.

2016-04-27compilation_SUITE: Use explicit exportsBjörn Gustavsson
With 'export_all' it is easy to add a new test case function and forget to add its name to the list of test cases to run. While we are it, remove unused functions and add the forgotten test case on_load_inline/1.

2016-04-27Remove compilation_SUITE:long_string/1Björn Gustavsson
long_string/1 was written to test that long string were handled efficiently in beam_asm. Strings used to be stored in the string table chunk, but are currently literals. There does not seem that this test case is likely to find any bugs.
2016-04-27Move pattern-matching tests to match_SUITEBjörn Gustavsson
2016-04-27Remove toothless test compile_SUITE:missing_testheap/1Björn Gustavsson
missing_testheap/1 is no longer relevant for the following reasons: 1) Because of the literal pool introduced in R12, no test_heap instructions are needed in the guards. 2) beam_validator would abort the compilation if any needed test_heap instructions were missing.
2016-04-27misc_SUITE: Add missing export of integer_encoding/0Björn Gustavsson
The integer_encoding/1 test is supposed to be run with a tighter timetrap ensure that encoding of integer in BEAM files is efficient enough.
2016-04-27Move test cases from compilation_SUITE to beam_utils_SUITEBjörn Gustavsson
beam_utils_SUITE didn't exist when the two test cases were written.

2016-04-27Move tests from compilation_SUITE to record_SUITEBjörn Gustavsson
2016-04-27Move bit syntax test cases from compilation_SUITE to bs_match_SUITEBjörn Gustavsson
We used to put code that would crash the compiler into compilation_SUITE_data. That way we would have a failing test case to remind us to fix a bug. Nowadays, we generally fix the bug and write the test case at the same time. Therefore it makes more sense to put the test code directly into a test suite. Move out bin_syntax_1 through bin_syntax_5 test cases. Scrap bin_syntax_6 because it does not longer seems to be relevant. While we are it, rename the fun_shadow/1 test to size_shadow/1. Also make sure that the code produces the correct result.

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.
2016-04-25compiler: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
Use case in compile.erl is cryptographical so use crypto:strong_rand_bytes/1 instead. Use case in test suite is not cryptographical so use other test instead.
2016-04-25ssh: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
ssh use cases are cryptographical so use crypto:strong_rand_bytes/1 instead.
2016-04-25public_key: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
public_key use cases are cryptographical so use crypto:strong_rand_bytes/1 instead.
2016-04-25ssl: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
ssl already used crypto:strong_rand_bytes/1 for most operations as its use cases are mostly cryptographical. Now crypto:strong_rand_bytes/1 will be used everywhere. However crypto:rand_bytes/1 was used as fallback if crypto:strong_rand_bytes/1 throws low_entropy, this will no longer be the case. This is a potential incompatibility. The fallback was introduced a long time ago for interoperability reasons. Now days this should not be a problem, and if it is, the security compromise is not acceptable 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.

* bjorn/compiler/remove-timestamps/OTP-13504: Remove timestamps from BEAM files
2016-04-25Remove timestamps from BEAM filesBjörn Gustavsson
As long as anyone can remember, the compilation time has been included in BEAM files (and can be retrieved using Mod:module_info(compile)). The timestamp has caused problems for anyone using tools such as 'cmp' to compare BEAM files or for package managers: http://erlang.org/pipermail/erlang-questions/2016-April/088717.html Rarely has the timestamp been of any use. Yes, sometimes the timestamp could help to figuring out which version of a module was used, but nowadays a better way is to use Mod:module_info(md5). To get rid of this problem, remove the timestamp from BEAM files in OTP 19. Don't add an option to include timestamps. Utilities that depend on the timestamp will need to be modified. For example: http://erlang.org/pipermail/erlang-questions/2016-April/088730.html Instead of using the compilation time, the MD5 for the BEAM code can be used. Example: 1> c:module_info(md5). <<79,26,188,243,168,60,58,45,34,69,19,222,138,190,214,118>> 2> beam_lib:md5(code:which(c)). {ok,{c,<<79,26,188,243,168,60,58,45,34,69,19,222,138,190,214,118>>}} 3>
