2015-05-22code: Eliminate dialyzer warnings for unmatched returnsBjörn Gustavsson
We want to have the core applications of Erlang/OTP free from any dialyzer warnings. Eliminate the warnings for unmatched returns that were introduced in 7309ff4c3832.
2015-05-22Fix parsing of IPv6 addresses to limit leading zerosRory Byrne
The current implementations of inet:parse_ipv6_address/1 and inet:parse_ipv6strict_address/1 permit address strings which have an unlimited number of leading zeros. Addresses such as: "0000000000000000000000000000000ffff::" "::00000000000000000000000000000000000000000000000000000000" "::0000000f435:1" If we are using this facility to validate string representations of IPv6 addresses, then we would end up validating addresses which are non-conformant (with respect to RFC 4291 section 2.2) and potentially dangerous. This patch ensures that each segment of an IPv6 address has a maximum of 4 hex digits.

2015-05-07code: Make load_native_code_for_all_loaded/0 comply to specBjörn Gustavsson
7309ff4c38325 introduced a mismatch between load_native_code_for_all_loaded/0 and its spec. We could just delete spec, but it is cleaner to ensure that the function always returns 'ok'. Noticed-by: Tuncer Ayaz
2015-05-07Set module_info md5 for native modules properlyRichard Carlsson
Use the md5 of the native code chunk instead of the Beam code md5.

* bjorn/kernel/code-loading: kernel application: Start code server first code: Reduce overhead of native code checking for loaded modules
2015-05-06kernel application: Start code server firstBjörn Gustavsson
When the code server has started, it will read the .beam files for all loaded modules to see whether they contain native code that should be loaded. To make that as fast as possible when we have no native code, start the code server as early as possible to minimize the number .beam files that must be read from disk. The code server does not use the 'file' module, so it is OK to start the code server before starting the file_server process. On my computer, the time for checking the loaded modules for native code is reduced from roughly 2 ms to 1.5 ms.
2015-05-06code: Reduce overhead of native code checking for loaded modulesBjörn Gustavsson
When the code server has been started, the function load_native_code_for_all_loaded/0 will check whether the .beam files for all loaded modules contain any native code. If there is native code, it will be loaded. If there is no native code, on my computer the check will take about 10 ms. That time can be reduced to about 2 ms if we replace the call to code beam_lib:chunks/2 with a call to prim_file:read_file/1 to read the file and a call to code:get_chunk/2 to check whether the chunk for native code is present. Furthermore, the entire check can be spawned off to a separate process and done in parallel with OTP starting up.

2015-04-22Fix problem with unitialized edlin text bufferPeter Andersson
Also make it possible to copy text buffer from current group process to the JCL mode
2015-04-22Fix shell crash when in switch command modeJonas Falkevik
The user_drv process can crash if ctrl-y is pressed when in switch command mode (ctrl-g). This is due to switch mode using edlin to parse the input. And edlin uses the process dictionary to store the kill_buffer. However the kill_buffer is undefined if not initialized by edlin:init/0 which makes the user_drv process crash since edlin is calling list:reverse/2 with undefined. Fix calles edlin:init/0 once before server_loop is entered.

2015-04-09Don't throw exception on prim_inet:setopt/3 errorHolger Weiß
Let gen_tcp:controlling_process/2 and inet_sctp:connect/[45] propagate prim_inet:setopt/3 errors instead of having them generate badmatch exceptions.

2015-03-20Replace usage of erlang:now() with usage of new APIRickard Green
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.

This commit introduces two BIFs: * erts_internal:map_type/1 * erts_internal:map_hashmap_children/1 erts_internal:map_hashmap_children/1 is only intended for use within erts_debug:size/1 since the internal hashmap node is not allowed to leak anywhere.
2015-03-10kernel: Fix file:read_line/1 unicode error handlingDan Gudmundsson
When a file was opened with some unicode encoding, file:read_line/1 could return unicode codepoints > 255 in list mode and wrong error message in bin mode. Chose to break out 'get_line' functionality from get_chars/5 since 'get_until' handling is different (comes from io module which should return unicode lists) and seems to have its own (doc?) problems.
