This document describes the changes made to the Kernel application.

+
Kernel 6.0 + +
Fixed Bugs and Malfunctions + + +

Clarify the documentation of rpc:multicall/5. +

+

+ Own Id: OTP-10551

+ + +

+ The DNS resolver when getting econnrefused from a server + retained an invalid socket so look up towards the next + server(s) also failed.

+

+ Own Id: OTP-13133 Aux Id: PR-1557

+ + +

+ No resolver backend returns V4Mapped IPv6 addresses any + more. This was inconsistent before, some did, some did + not. To facilitate working with such addresses a new + function inet:ipv4_mapped_ipv6_address/1 has been + added.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-13761 Aux Id: ERL-503

+ + +

+ The type specifications for file:posix/0 and + inet:posix/0 have been updated according to which + errors file and socket operations should be able to + return.

+

+ Own Id: OTP-14019 Aux Id: ERL-550

+ + +

+ Fix name resolving in IPv6 only environments when doing + the initial distributed connection.

+

+ Own Id: OTP-14501

+ + +

File operations used to accept filenames + containing null characters (integer value zero). This + caused the name to be truncated and in some cases + arguments to primitive operations to be mixed up. + Filenames containing null characters inside the filename + are now rejected and will cause primitive file + operations to fail.

Also environment variable + operations used to accept names and + values of + environment variables containing null characters (integer + value zero). This caused operations to silently produce + erroneous results. Environment variable names and values + containing null characters inside the name or value are + now rejected and will cause environment variable + operations to fail.

Primitive environment + variable operations also used to accept the $= + character in environment variable names causing various + problems. $= characters in environment variable + names are now also rejected.

Also + os:cmd/1 now + reject null characters inside its command. +

erlang:open_port/2 + will also reject null characters inside the port name + from now on.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-14543 Aux Id: ERL-370

+ + +

os:putenv and os:getenv no longer access + the process environment directly and instead work on a + thread-safe emulation. The only observable difference is + that it's not kept in sync with libc + getenv(3) / putenv(3), so those who relied + on that behavior in drivers or NIFs will need to add + manual synchronization.

On Windows this means that + you can no longer resolve DLL dependencies by modifying + the PATH just before loading the driver/NIF. To + make this less of a problem, the emulator now adds the + target DLL's folder to the DLL search path.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+ + +

+ Fixed connection tick toward primitive hidden nodes + (erl_interface) that could cause faulty tick timeout in + rare cases when payload data is sent to hidden node but + not received.

+

+ Own Id: OTP-14681

+ + +

+ Make group react immediately on an EXIT-signal from shell + in e.g ssh.

+

+ Own Id: OTP-14991 Aux Id: PR1705

+ + +

+ Calls to gen_tcp:send/2 on closed sockets now returns + {error, closed} instead of + {error,enotconn}.

+

+ Own Id: OTP-15001

+ + +
+ + +
Improvements and New Features + + +

+ A new logging API is added to OTP. This is implemented in + the Kernel application, module logger.

+

+ Legacy calls to error_logger will be automatically + redirected to the new API.

+

+ See the reference manual for module logger, and the + User's Guide for the Kernel application for more + information.

+

+ Own Id: OTP-13295

+ + +

+ The function inet:i/0 has been documented.

+

+ Own Id: OTP-13713 Aux Id: PR-1645

+ + +

+ New functionality for implementation of alternative + carriers for the Erlang distribution has been introduced. + This mainly consists of support for usage of distribution + controller processes (previously only ports could be used + as distribution controllers). For more information see + ERTS + User's Guide ➜ How to implement an Alternative Carrier + for the Erlang Distribution ➜ Distribution + Module.

+

+ Own Id: OTP-14459

+ + +

seq_trace labels may now be any erlang + term.

+

+ Own Id: OTP-14899

+ + +

+ The SSL distribution protocol -proto inet_tls has + stopped setting the SSL option + server_name_indication. New verify funs for client + and server in inet_tls_dist has been added, not + documented yet, that checks node name if present in peer + certificate. Usage is still also yet to be documented.

+

+ Own Id: OTP-14969 Aux Id: OTP-14465, ERL-598

+ + +

+ Changed timeout of gen_server calls to auth + server from default 5 seconds to infinity.
