Introduce new "Dbgi" chunk OTP-14369
2017-04-25Store abstract code in the Dbgi chunkJosé Valim
The new Dbgi chunk returns data in the following format: {debug_info_v1, Backend, Data} This allows compilers to store the debug info in different formats. In order to retrieve a particular format, for instance, Erlang Abstract Format, one may invoke: Backend:debug_info(erlang_v1, Module, Data, Opts) Besides introducing the chunk above, this commit also: * Changes beam_lib:chunk(Beam, [:abstract_code]) to read from the new Dbgi chunk while keeping backwards compatibility with old .beams * Adds the {debug_info, {Backend, Data}} option to compile:file/2 and friends that are stored in the Dbgi chunk. This allows the debug info encryption mechanism to work across compilers * Improves dialyzer to work directly on Core Erlang, allowing languages that do not have the Erlang Abstract Format to be dialyzer as long as they emit the new chunk and their backend implementation is available Backwards compatibility is kept across the board except for those calling beam_lib:chunk(Beam, ["Abst"]), as the old chunk is no longer available. Note however the "Abst" chunk has always been optional. Future OTP versions may remove parsing the "Abst" chunk altogether from beam_lib once Erlang 19 and earlier is no longer supported. The current Dialyzer implementation still supports earlier .beam files and such may also be removed in future versions.
2017-04-24Add unicode_utilDan Gudmundsson
A base for unicode functions, not intended to be a user api. Whitespace returns a reasonable subset of non nobreak whitespace characters. Implementation notes: Make function clauses instead of using arrays and store tuples instead of maps to save space.

2016-01-20Introduce time warp safe replacement for safe_fixed optionRickard Green
The new time warp safe option is safe_fixed_monotonic_time which gives erlang:monotonic_time(). The safe_fixed option was also slightly changed. It now gives erlang:timestamp() instead of erlang:now(). This has however not been documented, so it is considered a compatible change. The above effects both ets, and dets. This commit also include the bugfix OTP-13239 for dets:info(Tab, safe_fixed). The timestamp in the result returned by dets:info(Tab, safe_fixed) was unintentionally broken as a result of the time API rewrites in OTP 18.0.

2015-04-30stdlib: Add module erl_annoHans Bolinder
Introduce erl_anno, an abstraction of the second element of tokens and tuples in the abstract format. The convention that negative line numbers can be used for silencing compiler warnings will no longer work in OTP 19; instead the annotation 'generated' is to be used.
2015-04-29stdlib: Add new random functionality/moduleKenji Rikitake
The old random module contains an old algorithm which have flaws and the api requires the user to invoke seed and or checking if seed have been invoked, if a non constant seed is to be used. The api contains the following features: - The user can invoke rand:unform/[0|1] directly and get a non constant seeding. - The api is split in functional and non functional functions, i.e. usage of _s functions will not affect the process dictionary. - The api contains several algorithms with different characteristics and can be extended with new algorithms in the future. - Contains state of the art random number generators. - Default algorithm is taylor made for erlang to be fast on 64bits machines.

2014-04-26Remove the pg module and related documentationLoïc Hoguin
This module has been marked experimental for more than 15 years, and has largely been superseded by the pg2 module from the kernel application. The original pg also has no tests and has not been updated in the last 15 years other than small maintenance edits (like adding specs or replacing pid/1 by is_pid/1). It is pretty unlikely that anyone uses it today and its presence is simply confusing as people should be using pg2 anyway.
2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.
