This commit also adds a check to see that all files that are part of an xi:include also have part of XML_FILES and vice versa. It also fixes any applications where this was not true.

2017-04-27stdlib: Improve the Erlang shell's handling of referencesHans Bolinder
As of Erlang/OTP 20.0, the type of ETS tables, ets:tid(), is a reference(). A request was put forward that the Erlang shell should be able to handle references in its input. This commit introduces an extended parser in module lib. It can parse pids, ports, references, and external funs under the condition that they can be created in the running system. The parser is meant to be used internally in Erlang/OTP. The alternative, to extend erl_scan and erl_parse, was deemed inferior as it would require the abstract format be able to represent pids, ports, references, and funs, which would be confusing as they are not expressions as such, but data types.

"Tuples funs" was removed a long time ago. There is no need to even mention them.

2016-12-20erts: Correct memory footprint for mapsSverker Eriksson
Small map was wrong as we should include our own top Eterm and exclude them for keys and values. Large maps was wrong as it described the theoretical minimum of a full tree, which does not happen in reality.

Thanks to Joe Armstrong for the suggestion.
2016-12-19Shorten the tail-recursion mythBjörn Gustavsson
The myth about tail recursion being faster than body recursion still seems to be alive, but we don't need to spend that much space discussing it as we needed earlier. Shorten the discussion and include a link to to Fred Hebert's excellent blog post.

2015-03-20Introduce a new time APIRickard Green
The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.
