./lang/erlang, Concurrent functional programming language

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 21.2.3, Package name: erlang-21.2.3, Maintainer: pkgsrc-users

Erlang is a programming language which has many features more commonly
associated with an operating system than with a programming language:
concurrent processes, scheduling, memory management, distribution,
networking, etc.

The initial open-source Erlang release contains the implementation of
Erlang, as well as a large part of Ericsson's middleware for building
distributed high-availability systems.

  OTP-15501    Application(s): compiler
               Related Id(s): ERL-514, ERL-807, OTP-14808

               An optimization that avoided allocation of a stack
               frame for some case expressions was introduced in OTP
               21. (ERL-504/OTP-14808) It turns out that in rare
               circumstances, this optimization is not safe.
               Therefore, this optimization has been disabled.

               A similar optimization will be included in OTP 22 in a
               safe way.

               Fixed bug in atomics with option {signed,false} when
               returned values are (1 bsl 63) or larger. Could cause
               heap corruption leading to VM crash or other unpleasant

  OTP-13468    Application(s): erts, sasl

               New counters and atomics modules supplies access to
               highly efficient operations on mutable fixed word sized
               variables.

  OTP-14669    Application(s): erts
               Related Id(s): PR-1989

               There is a new module persistent_term that implements a
               term storage suitable for terms that are frequently
               used but never or infrequently updated. Lookups are
               done in constant time without copying the terms.

  OTP-15094    Application(s): ssh
               Related Id(s): OTP-15419

               Added public key methods ssh-ed25519 and ssh-ed448.

               Requires OpenSSL 1.1.1 or higher as cryptolib under the
               OTP application crypto.

  OTP-15449    Application(s): ssl

               *** POTENTIAL INCOMPATIBILITY ***

               ssl now uses active n internally to boost performance.
               Old active once behavior can be restored by setting
               application variable see manual page for ssl
               application (man 6).

  OTP-15475    Application(s): erts
               Related Id(s): ERIERL-229

               Add a new pollset that is made to handle sockets that
               use {active, true} or {active, N}. The new pollset will
               not be polled by a pollthread, but instead polled by a
               normal scheduler.

               This change was made because of the overhead associated
               with constantly having to re-apply the ONESHOT
               mechanism on fds that all input events were
               interesting.

               The new pollset is only active on platforms that
               support concurrent kernel poll updates, i.e. Linux and
               BSD.

 --- POTENTIAL INCOMPATIBILITIES -------------------------------------
 ---------------------------------------------------------------------

  OTP-15364    Application(s): kernel

               A new function, logger:update_handler_config/3 is
               added, and the handler callback changing_config now has
               a new argument, SetOrUpdate, which indicates if the
               configuration change comes from set_handler_config/2,3
               or update_handler_config/2,3.

               This allows the handler to consistently merge the new
               configuration with the old (if the change comes from
               update_handler_config/2,3) or with the default (if the
               change comes from set_handler_config/2,3).

               The built-in handlers logger_std_h and
               logger_disk_log_h are updated accordingly. A bug which
               could cause inconsistency between the handlers'
               internal state and the stored configuration is also
               corrected.

               Fixed a rare internal consistency failure caused by a
               bug in the beam_jump pass. (Thanks to Simon Cornish for
               reporting this bug.)

  OTP-15435    Application(s): compiler
               Related Id(s): ERL-778

               The compiler could fail with an internal consistency
               check failure when compiling code that used the

  OTP-15245    Application(s): compiler, stdlib
               Related Id(s): ERL-706

               When specified, the +{source,Name} option will now
               override the actual file name in stack traces, instead
               of only affecting the return value of
               Mod:module_info().

               The +deterministic flag will also affect stack traces
               now, omitting all path information except the file
               name, fixing a long-standing issue where deterministic
               builds required deterministic paths.

  OTP-12242    Application(s): erts
               Related Id(s): ERL-561

               When a process was waiting for a TCP socket send
               operation to complete, and another process closed the
               socket during that send, the sending process could
               hang. This bug has now been corrected.

  OTP-15343    Application(s): erts, stdlib

               Document bit_size in match specifications and allow it
               in ets:fun2ms.

  OTP-15346    Application(s): erts

               Fixed bug in ets:select_replace when called with a
               fully bound key could cause a following call to
               ets:next or ets:prev to crash the emulator or return
               invalid result.

  OTP-15360    Application(s): erts

               When a module has been purged from memory, any literals
               belonging to that module will be copied to all
               processes that hold references to them. The max heap
               size limit would be ignored in the garbage collection
               initiated when copying literals to a process. If the
               max heap size was exceeded, the process would typically
               be terminated in the following garbage collection.
               Corrected to terminate the process directly if copying
               a literal would exceed the max heap size.

  OTP-15389    Application(s): erts

               Fix compilation of run_erl on Solaris 11.4 and later.

  OTP-15436    Application(s): erts

               Fixed a bug where lists:reverse/1-2 could use far too

  OTP-15461    Application(s): erts
               Related Id(s): ERL-784

               Fixed bug in file:sendfile when the send operation
               failed. For sockets in active modes it could cause
               emulator crash or a hanging call. For sockets with
               {active,false} an unexpected {inet_reply, _, _} message
               could be sent to the calling process. The bug exists
               since OTP-21.0.

  OTP-15465    Application(s): erts

               The erts configure script has been updated to reject

               Add a new pollset that is made to handle sockets that
               use {active, true} or {active, N}. The new pollset will
               not be polled by a pollthread, but instead polled by a
               normal scheduler.

               This change was made because of the overhead associated
               with constantly having to re-apply the ONESHOT
               mechanism on fds that all input events were
               interesting.

               The new pollset is only active on platforms that

               *** POTENTIAL INCOMPATIBILITY ***

               A new function, logger:update_handler_config/3 is
               added, and the handler callback changing_config now has
               a new argument, SetOrUpdate, which indicates if the
               configuration change comes from set_handler_config/2,3
               or update_handler_config/2,3.

               This allows the handler to consistently merge the new
               configuration with the old (if the change comes from
               update_handler_config/2,3) or with the default (if the
               change comes from set_handler_config/2,3).

               The built-in handlers logger_std_h and
               logger_disk_log_h are updated accordingly. A bug which
               could cause inconsistency between the handlers'

               During system start, logger has a simple handler which
               prints to stdout. After the kernel supervision is
               started, this handler is removed and replaced by the
               default handler. Due to a bug, logger earlier issued a
               debug printout saying it received an unexpected
               message, which was the EXIT message from the simple
               handler's process. This is now corrected. The simple
               handler's process now unlinks from the logger process
               before terminating.

               A bug where the socket option 'pktoptions' caused a
               read of uninitialized memory has been fixed. Would
               cause malfunction on FreeBSD.

               Correct alert handling with new TLS sender process,
               from ssl-9.0.2. CLOSE ALERTS could under some
               circumstances be encoded using an incorrect cipher
               state. This would cause the peer to regard them as
               unknown messages.

  OTP-15348    Application(s): ssl

               socket option {packet, 1|2|3|4} with ssl:setopts/2 the
               option must internally be propagated to the sender
               process as well as the reader process as this

  OTP-15133    Application(s): ssh
               Related Id(s): OTP-15240

               The key exchange methods
               'curve25519-sha256@libssh.org', 'curve25519-sha256' and
               'curve448-sha512' are implemented. The last two are
               defined in
               https://tools.ietf.org/html/draft-ietf- … ssh-curves

               They all depends on that OpenSSL 1.1.1 or higher is
               used as cryptolib.

  OTP-15134    Application(s): crypto, public_key

               The typing in the CRYPTO and PUBLIC_KEY applications
               are reworked and a few mistakes are corrected.

               The documentation is now generated from the typing and
               some clarifications are made.

               A new chapter on Algorithm Details such as key sizes
               and availability is added to the CRYPTO User's Guide.

  OTP-15145    Application(s): erts, kernel
               Related Id(s): ERIERL-187

               The socket options recvtos, recvttl, recvtclass and
               pktoptions have been implemented in the socket modules.
               See the documentation for the gen_tcp, gen_udp and inet
               modules. Note that support for these in the runtime
               system is platform dependent. Especially for pktoptions
               which is very Linux specific and obsoleted by the RFCs
               that defined it.

  OTP-15209    Application(s): ssh
               Related Id(s): OTP-15164

               The cipher 'chacha20-poly1305@openssh.com' is now
               supported if OpenSSL 1.1.1 or higher is used as

  OTP-14440    Application(s): asn1
               Related Id(s): ERIERL-220

               A bug in ASN.1 BER decoding has been fixed. When
               decoding a recursively enclosed term the length was not
               propagated to that term decoding, so if the length of
               the enclosed term was longer than the enclosing that
               error was not detected.

               A hard coded C stack limitation for decoding recursive
               ASN.1 terms has been introduced. This is currently set
               to 8 kWords giving a nesting depth of about 1000
               levels. Deeper terms can not be decoded, which should
               not be much of a real world limitation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15307    Application(s): common_test

               The Logger handler cth_log_redirect earlier called the
               report callback (report_cb) before calling the logger
               formatter. In some cases this would fail, since
               cth_log_redirect could not handle report callbacks with
               two arguments. This is now corrected, so only the
               formatter will call the report callback.

  OTP-15188    Application(s): compiler
               Related Id(s): ERL-658

               When compiling from Core Erlang, funs created in
               certain expressions that were only used for their
               side-effects were subtly broken.

  OTP-15218    Application(s): compiler
               Related Id(s): ERL-684

               There could be an internal consistency failure when a
               receive was nested in a try/catch.

  OTP-15219    Application(s): compiler
               Related Id(s): ERL-689

               In rare circumstances, the matched out tail of a binary
               could be the entire original binary.

  OTP-15227    Application(s): compiler
               Related Id(s): ERL-699

               When is_map_key/2 was used in a guard together with the
               not/1 or or/2 operators, the error behavior could be
               wrong when is_map_key/2 was passed a non-map as the
               second argument.

               In rare circumstances, compiling code that uses
               is_map_key/2 could cause an internal consistency check
               failure.

  OTP-15235    Application(s): compiler
               Related Id(s): ERL-703

               The compiler could crash when compiling a function with

               The RSA options rsa_mgf1_md, rsa_oaep_md, and
               rsa_oaep_label were always disabled. They will now be
               enabled when a suitable cryptolib is used.

               They are still experimental and may change without
               prior notice.

  OTP-15283    Application(s): crypto

               The ciphers aes_ige256 and blowfish_cbc had naming
               issues in crypto:next_iv/2.

  OTP-15303    Application(s): crypto

               the RSA_SSLV23_PADDING is disabled if LibreSSL is used
               as cryptlib. This is due to compilation problems.

               This will be investigated further in the future.

  OTP-15205    Application(s): erts

               Fix bug where ctrl-break or ctrl-c would not trigger
               the break mode properly on Windows. This bug was
               introduced in erts-10.0 (OTP-21).

  OTP-15206    Application(s): erts

               Fix a performance bug for reception of UDP packages,
               where a memory buffer would be reallocated when it
               should not have been.

               Introduce a limit on the maximum automatic increase of
               the UDP user-space buffer to the theoretical max of the
               network PATH, i.e. 65535.

  OTP-15208    Application(s): erts

               Fix alignment of erts allocator state internally in
               erts. With the improper alignment the emulator would
               refuse to start when compiled with clang on 32-bit
               systems.

  OTP-15210    Application(s): erts

               Fix bug where too many concurrent calls to
               erlang:open_port({spawn,"cmd"},...) would result in the
               emulator terminating with the reason "Failed to write

               descriptors from the pollset when closing the port.
               Without this fix the same file descriptor number could

               results. Bug exists since OTP-21.0.

  OTP-15278    Application(s): erts

               Fixed bug in erlang:memory causing ets to report too
               much. This small false memory leak (16 bytes each time)
               can only happen when a specific race condition occurs

               sent to c-node even if there are unsent buffered data,
               as c-nodes need ticks in order to send reply ticks. The

               Related Id(s): ERIERL-206

               Conversion of (agent) Audit Trail Log (ATL) failed due
               to invalid log entries.

               The conversion aborted completely midway because the
               ATL contained invalid entries. The conversion has been
               improved so that it now firstly handles encountered
               errors and write an informative message (into the
               converted stream) and secondly keeps count of the
               number of successful or failed entry conversions. See
               log_to_txt for more info.

               The reason the ATL contained invalid entries have also
               been fixed. The reason was that for some outgoing
               messages (not response):

               -- encrypted (v3 messages)

               Was logged "as is" (encrypted) without the info to
               decrypt, making conversion impossible (which was the
               reason the log contained bad entries).

               -- un-encrypted

               Was not logged at all.

  OTP-12983    Application(s): ssl

               TLS will now try to order certificate chains if they
               appear to be unordered. That is prior to TLS 1.3,
               тАЬcertificate_listтАЭ ordering was required to be strict,
               however some implementations already allowed for some
               flexibility. For maximum compatibility, all
               implementations SHOULD be prepared to handle
