This document describes the changes made to the Kernel application.

+
Kernel 5.3 + +
Fixed Bugs and Malfunctions + + +

+ Fix bug where gethostname would incorrectly fail with + enametoolong on Linux.

+

+ Own Id: OTP-14310

+ + +

+ Fix bug causing code:is_module_native to falsely + return true when local call trace is enabled for + the module.

+

+ Own Id: OTP-14390

+ + +

+ Add early reject of invalid node names from distributed + nodes.

+

+ Own Id: OTP-14426

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

+ Since Unicode is now allowed in atoms an extra check is + needed for node names, which are restricted to Latin-1.

+

+ Own Id: OTP-13805

+ + +

Replaced usage of deprecated symbolic time + unit representations.

+

+ Own Id: OTP-13831 Aux Id: OTP-13735

+ + +

file:write_file(Name, Data, [raw]) would turn + Data into a single binary before writing. This + meant it could not take advantage of the writev() + system call if it was given a list of binaries and told + to write with raw mode.

+

+ Own Id: OTP-13909

+ + +

The performance of the disk_log has been + somewhat improved in some corner cases (big items), and + the documentation has been clarified.

+

+ Own Id: OTP-14057 Aux Id: PR-1245

+ + +

Functions for detecting changed code has been added. + code:modified_modules/0 returns all currently + loaded modules that have changed on disk. + code:module_status/1 returns the status for a + module. In the shell and in c module, mm/0 + is short for code:modified_modules/0, and + lm/0 reloads all currently loaded modules that + have changed on disk.

+

+ Own Id: OTP-14059

+ + +

+ Introduce an event manager in Erlang to handle OS + signals. A subset of OS signals may be subscribed to and + those are described in the Kernel application.

+

+ Own Id: OTP-14186

+ + +

Sockets can now be bound to device (SO_BINDTODEVICE) + on platforms where it is supported.

This has + been implemented e.g to support VRF-Lite under Linux; see + + VRF , and GitHub pull request #1326. +

+

+ Own Id: OTP-14357 Aux Id: PR-1326

+ + +

+ Added option to store shell_history on disk so that the + history can be reused between sessions.

+

+ Own Id: OTP-14409 Aux Id: PR-1420

+ + +

The size of crash reports created by + gen_server, gen_statem and proc_lib + is limited with aid of the Kernel application variable + error_logger_format_depth. The purpose is to limit + the size of the error_logger process when + processes with huge message queues or states crash.

+

The new function + error_logger:get_format_depth/0 can be used to + retrieve the value of the Kernel application variable + error_logger_format_depth.

+

+ Own Id: OTP-14417

+ + +

One of the ETS tables used by the global + module is created with {read_concurrency, true} in + order to reduce contention.

+

+ Own Id: OTP-14419

+ + +

+ Warnings have been added to the relevant documentation + about not using un-secure distributed nodes in exposed + environments.

+

+ Own Id: OTP-14425
