This document describes the changes made to the ERTS application.

+
Erts 11.0 + +
Fixed Bugs and Malfunctions + + +

+ Do not allocate new bitstring/binary when an empty binary + is appended.

+

+ Own Id: OTP-15535 Aux Id: PR-2055

+ + +

+ Document that process_info(_, current_function) + can return {current_function, undefined} in case + of execution of native code.

+

+ Own Id: OTP-15543 Aux Id: PR-2089

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

+ Add support for Erlang Distribution protocol to split the + payload of large signals into several fragments. This + allows other processes to communicate uninterrupted + during the transmission of these signals.

+

+ Own Id: OTP-13397

+ + +

+ A simple socket API has been provided through the socket + module. Known issues are; No support for the Windows OS + (currently), a small term leakage.

+

+ Own Id: OTP-14831

+ + +

Added NIF functions enif_set_pid_undefined, + enif_is_pid_undefined + and enif_compare_pids.

+

+ Own Id: OTP-15011 Aux Id: PR-2147

+ + +

Underutilized memory segments (carriers) can now move + between all allocator instances, rather than just between + instances of the same type, which greatly reduces memory + usage in some scenarios.

+

+ Own Id: OTP-15063

+ + +

The emulator will now mark free blocks in pooled + carriers with madvise(2) + MADV_FREE (or similar), + letting the OS reclaim the associated physical memory if + necessary.

+

+ Own Id: OTP-15075

+ + +

+ New ERL_NIF_SELECT_CANCEL feature added to + enif_select in order to cancel (or "deselect") a + read or write event on a previously selected file + descriptor.

+

+ Own Id: OTP-15095

+ + +

+ ETS option write_concurrency now also affects and + improves the scalability of ordered_set tables. + The implementation is based on a data structure called + contention adapting search tree, where the lock + granularity adapts to the actual amount of concurrency + exploited by the applications in runtime.

+

+ Own Id: OTP-15128

+ + +

+ Build configuration of the crypto application has + been moved from the erts application into the + crypto application.

+

+ Own Id: OTP-15129

+ + +

Anonymous functions that don't capture environment are + now created at load-time instead of in run-time.

+

+ Own Id: OTP-15195 Aux Id: PR-1812

+ + +

+ Optimize updates of maps with identical keys and values. + E.g. in the example below the original Map will be reused + as the return of the update.

+

+ 1> Map = #{ a => b }. #{ a => b } 2> Map#{ a := b }.

+

+ Own Id: OTP-15211 Aux Id: PR-1889

+ + +

+ Optimize binary:match/2 and + binary:matches/2 to use memchr internally.

+

+ Own Id: OTP-15238 Aux Id: PR-1803

+ + +

+ The runtime system used to terminate when a message + larger than 2 Gb was passed over the distribution. The + send operation will now instead throw a + system_limit exeption.

+

+ Own Id: OTP-15261

+ + +

+ Change the first module called by erts to be names + erl_init instead of otp_ring0. systools in sasl have been + updated to reflect this change.

+

+ Own Id: OTP-15336 Aux Id: PR-1825

+ + +

+ Minor adjustments made to build system for parallel + configure.

+

+ Own Id: OTP-15340 Aux Id: OTP-14625

+ + +

+ Two new NIF interface functions enif_select_read + and enif_select_write. They are similar to + existing enif_select but allow a custom event + message as argument.

+

+ Own Id: OTP-15349 Aux Id: PR-2084

+ + +

The embedded copy of zlib has been updated from + 1.2.8 to 1.2.11.

+

Note that this copy is only used as a fallback when + the target platform doesn't provide any zlib + development libraries. If your system provides + zlib then it will be used even if it is older than + 1.2.11.

+

+ Own Id: OTP-15351 Aux Id: ERL-749

+ + +

+ New NIF function enif_make_monitor_term.

+

+ Own Id: OTP-15362 Aux Id: PR-2127

+ + +

Appending lists (The ++ operator) will now yield + properly on large inputs.

+

+ Own Id: OTP-15427

+ + +

The length/1 BIF used to calculate the length + of the list in one go without yielding, even if the list + was very long. In OTP 22, length/1 will yield when + called with a long lists.

+

+ Own Id: OTP-15439

+ + +

The transitory emulator option +ztma true + (introduced in OTP 21.3) has been removed.

+

+ Own Id: OTP-15581 Aux Id: OTP-15580

+ + +

+ The termination behaviour of processes has changed to + allow processes to yield while sending link exit/monitor + down signals.

+

+ Own Id: OTP-15610

+ + +

+ The dist messages EXIT, EXIT2 and MONITOR_DOWN have been + updated with new versions that send the reason term as + part of the payload of the message instead of as part of + the control message.

+

+ The old versions are still present and can be used when + communicating with nodes that don't support the new + versions.

+

+ Own Id: OTP-15611

+ + +

+ When sending messages, exit, exit2 and monitor down + distributed signals, the process sending will now yield + appropriately.

+

+ This means that a terminating process will yield and + possibly be suspended on busy distribution entries while + they are terminating. This means that any memory held by + such processes will not be released until after all + exit/monitor down signals have been sent.

+

+ Own Id: OTP-15612

+ + +

+ All external pids/ports/refs created by + erlang:list_to_pid and similar functions now compare + equal to any other pid/port/ref with the same number from + that node.

+

+ Before this change they compared differently because the + node creation of the pid/port/ref did not compare equal + to any real pid/port/ref creation.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-15613

+ + +

The iolist_size/1 function is now yielding + which means that an Erlang/OTP system will be responsive + even if the applications running on the system frequently + call iolist_size/1 with large iolists.
