* wx: Fix build problems when wxWidgets are built with -enable-
std.
* wx: Commit of generated configure script.
* crypto: Removed a risk for coredump.
* crypto: Fixed and documented the DED_LDFLAGS_CONFTEST
configuration variable in $ERL_TOP/HOWTO/INSTALL.md.
* crypto: Commit of generated configure script.
* common_test: Commit of generated configure script.

- Version 24.0:
- Highlights compiler:
* The compiler will now inline funs that are used only once
immediately after their definition.
* Compiler warnings and errors now include column numbers in
addition to line numbers.
* Variables bound between the keywords 'try' and 'of' can now
be used in the clauses following the 'of' keyword (that is,
in the success case when no exception was raised).
* Generators in list and binary comprehensions will now raise a
{bad_generator,Generator} exception if the generator has an
incorrect type Similarly, when a filter does not evaluate to
a boolean, a {bad_filter,Filter} exception will be raised.
* Warnings for expressions whose result was ignored that could
be suppressed by using the anonymous variable '_' can now be
suppressed with a variable beginning with '_'.
* Selective receive optimization will now be applied much more
often. The new recv_opt_info compile flag can be used to
print diagnostics relating to this optimization. You can read
more about the selective receive optimization in the
Efficiency Guide.
- erts, kernel, stdlib:
* hex encoding and decoding functions added in the binary module
* The BeamAsm JIT-compiler has been added to Erlang/OTP and
will give a significant performance boost for many
applications. The JIT-compiler is enabled by default on most
x86 64-bit platforms that have a C++ compiler that can
compile C++17. To verify that a JIT enabled emulator is
running you can use erlang:system_info(emu_flavor).
* A compatibility adaptor for gen_tcp to use the new socket API
has been implemented (gen_tcp_socket).
* Extended error information for failing BIF calls as proposed
in EEP 54 has been implemented.
* Process aliases as outlined by EEP 53 has been introduced.
* Implementation of EEP 56 in supervisor. It adds the concept
of significant children as well as the auto_shutdown
supervisor flag. See the supervisor manual page for more
information.
- ftp:
* Add support for FTPES (explicit FTP over TLS).
- ssl:
* Make TLS handshakes in Erlang distribution concurrent.
* TLS connections now support EdDSA certificates.
- wx:
* The application has been completely rewritten in order to use
wxWidgets version 3 as its base.
* Added support for wxWebView.
- edoc:
* EDoc is now capable of emitting EEP-48 doc chunks. This means
that, with some configuration, community projects can now
provide documentation for shell_docs the same way that OTP
libraries did since OTP 23.0.

- Use wxWidgets < 3.1 (boo#1180488)
- Changes for 23.2.2:
* crypto: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* odbc: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* snmp: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* erts: The suspend_process() and resume_process() BIFs did not
check their arguments properly which could cause an emulator
crash.
* erts: The runtime system would get into an infinite loop if the
runtime system was started with more than 1023 file descriptors
already open.
* megaco: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* erl_interface: Integers outside of the range [-(1 bsl 32) - 1,
(1 bsl 32) -1] were previously intended to be printed in an
internal bignum format by ei_print_term() and
ei_s_print_term(). Unfortunately the implementation has been
buggy since OTP R13B02 and since then produced results with
random content which also could crash the calling program. This
fix replaces the printing of the internal format with printing
in hexadecimal form and extend the range for printing in
decimal form. Currently integers in the range [-(1 bsl 64), (1
bsl 64)] are printed in decimal form and integers outside of
this range in Erlang hexadecimal form.
* erl_interface: The ei API for decoding/encoding terms is not
fully 64-bit compatible since terms that have a representation

- Changes for 23.1.3:
* erts: Fixed a crash when exceptions were thrown during call
time tracing.
* ssh: A supervisor sub-tree could be left if the connection
handler process is brutally killed. This will make the
max_sessions checking option to count the existing sessions
erroneously and could finally block further sessions.
- Changes for 23.1.2:
* compiler: Fixed a bug in the boolean optimization pass that
caused the compiler to confuse different clauses.
* erts: Fixed bugs causing issues when enabling the ERTS internal
allocators on a system built with the undocumented and
unsupported SMALL_MEMORY feature.
* erts: The inet driver used to use 16 as maximum elements in an
I/O vector passed to writev() (and WSASend() on Windows). When
the data to send contained lots of elements, this caused a
performance degradation since repeated calls to writev() had to
be made to a much larger extent. The inet driver now looks up
actual maximum amount of elements that can be used on the
system, instead of just assuming 16. On most systems this will
result in a maximum amount of I/O vector elements of 1024. As
of OTP 23.0 the term encoding of signals to send over the
distribution are encoded into I/O vectors of buffers instead of
into a single buffer. Reference counted binaries are referred
to directly from the I/O vector instead of being copied into
the single buffer. That is, Erlang signals containing huge
amounts of reference counted binaries was effected by this
performance degradation.
* erts: In the distributed case, a faulty reply option in a call
to the spawn_request() BIF erroneously caused a badarg

- Changes for 23.1.1:
* erts: inet:setopts([{active,once}]) wakes up IO polling thread
unnecessarily, leading to lock contention and visibly higher
CPU utilization.
* erts: Two bugs in the ERTS internal thread wakeup functionality
have been fixed. These bugs mainly hit when all threads in the
system tried to go to sleep. When the bugs were triggered,
certain operations were delayed until a thread woke up due to
some other reason. Most important operations effected were code
loading, persistent term updates, and memory deallocation.
* erts: Fixed bug in ets:select_replace/2 on compressed tables
that could produce faulty results or VM crash. Bug exists since
OTP 20.
* erts: When compiling Erlang/OTP on macOS using Xcode 12, the
performance of the BEAM interpreter would be degraded.
* erts: As of OTP 22, the allocator specific memory carrier pools
were replaced by a node global carrier pool. This unfortunately
caused substantial memory fragmentation in some cases due to
long lived data being spread into carriers used by allocators
mainly handling short lived data. A new command line argument
+M<S>cp has been introduced with which one can enable the old
behavior as well as configuring other behaviors for the carrier
pools. In order to configure the old behavior, with allocator
specific carrier pools for all allocators, pass +Mucp :
(including the colon character) as a command line argument to
erl when starting the Erlang system. The default configuration
for carrier pools will be changed to +Mucp : some time in the
future, but not in this patch.
* os_mon: The configuration parameter
memsup_improved_system_memory_data has been introduced. It can

- Changes for 23.0.3:
* erts: Fixed bug in erlang:load_nif/2 that could cause it to
throw badarg exception if a concurrent code change operation
was in progress. Bug existed since OTP 23.0.
* erts: Minor fix of debug compiled VM.
* erts: An unintentional reuse of an already used emulator
internal event object could cause a wakeup signal to a thread
to be lost. In worst case this could cause the runtime system
to hang. This hang was however quite rare.
* erts: NIF threads and driver threads on non-Linux systems
leaked internal resources when terminating. On Windows these
resources were one event per thread. On most other systems one
mutex and one condition variable per thread. On these other
systems that also lacked pthread_cond_timedwait() also a pipe
with its file descriptors was leaked.
* compiler: When calls to is_map_key were repeated, the compiler
could terminate with an internal consistency failure.
* compiler: Fixed a bug in the type inference pass that could
cause the compiler to hang.

OBS-URL: https://build.opensuse.org/package/show/devel:languages:erlang:Factory/erlang?expand=0&rev=106
- Changes for 23.0.2:
* erts: Fixed bug when sending an export fun (eg lists:reverse/1)
on a not yet established connection. It could cause VM crash.
Bug exists since OTP 23.0.
* megaco: The mini parser could not properly decode some IPv6
addresses.
- Changes for 23.0.1:
* erts: The functionality utilized by BIFs for temporary
disabling of garbage collection while yielding could cause
system task queues to become inconsistent on a process
executing such a BIF. Process system tasks are for example
utilized when purging code, garbage collecting literal data,
and when issuing an ordinary garbage collection from another
process. The bug does not trigger frequently. Multiple code
purges in direct sequence makes it more likely that this bug is
triggered. In the cases observed, this has resulted in a
hanging code purge operation.
* erts: SCTP and UDP recv/2,3 hangs indefinitely if socket is
closed while recv is called (socket in passive mode).
* compiler: In rare circumstances, a guard using 'not' could
evaluate to the wrong boolean value.
* compiler: A guard expression that referenced a variable bound
to a boolean expression could evaluate to the wrong value.
- Version 23.0:
- Potential Incompatibilities:
* SSL:Support for SSL 3.0 is completely removed. TLS 1.3 is added
to the list of default supported versions.
* erl_interface: Removed the deprecated parts of erl_interface
(erl_interface.h and essentially all C functions with prefix

OBS-URL: https://build.opensuse.org/package/show/devel:languages:erlang:Factory/erlang?expand=0&rev=105
- Changes for 22.3:
* compiler: A 'receive' with an 'after 0' clause would prevent
the optimization that can avoid scanning the entire receive
queue when matching on a newly created reference.
* compiler: HiPE can again handle modules with catch and try
constructs.
* compiler: Fixed a bug in bit-syntax optimization that could
crash the compiler.
* crypto: Fixed potential memory leaks involving calls to the
crypto ng_api.
* common_test: Document incl_apps cover option
* common_test: The ct_property_test has now a report function for
results of stateful testing.
* common_test: Don't hide error reasons from user
* stdlib: Fix type specification for uri_string:normalize/2 that
may also return error().
* stdlib: Improve error handling in uri_string:normalize/2. This
change fixes a crash when the input URI has faulty percent-
encoding.
* stdlib: Fix minor bugs in the Erlang pretty printer (erl_pp).
* stdlib: Fix the Erlang parser regarding consecutive unary
operators.
* stdlib: Let calendar:rfc3339_to_system_time() crash when the
time offset is missing.
* stdlib: Implement uri_string:resolve/{2,3} that can be used to
resolve a URI reference against a base URI.
* stdlib: In gen_statem it is now possible to change the callback
module for a running server. See gen_statem's documentation for
change_callback_module, push_callback_module, and
pop_callback_module.
* ssl: Correct handling of TLS record limit in TLS-1.3. The max
value differs from previous versions. Also the payload data max
record check was broken, that is record overflow problems could
occur if user sent large amounts of data.
* ssl: Correct close handling for DTLS
* ssl: Fix ssl:getstat/1-2 to also work for DTLS sockets
* ssl: Correct internal handling och socket active mode to avoid
reviving TCP data aimed for a downgraded TLS socket.
* ssl: When using the host name as fallback for SNI (server name
indication) strip a possible trailing dot that is allowed in a
host name but not in the SNI. Also if the server receives a SNI
with a trailing dot send an UNRECOGNIZED_NAME alert.
* ssl: Immediately remove session entries if handshake is
abruptly closed at transport level.
* ssl: Implementation of the key and initialization vector update
feature, and general hardening of TLS 1.3. There are
cryptographic limits on the amount of plaintext which can be
safely encrypted under a given set of keys. This change
enforces those limits by triggering automatic key updates on
TLS 1.3 connections.
* ssl: Add support for TLS 1.3 Session Tickets (stateful and
stateless). This allows session resumption using keying
material from a previous successful handshake.
* ssl: Add support for key exchange with Edward curves and PSS-
RSA padding in signature verification.
* megaco: The documented function
megaco:get_sdp_record_from_PropertGroup/2 was a wrapper for
megaco_sdp:get_sdp_record_from_PropertGroup/2 but did not
actually exist. This has now been fixed.
* megaco: Test suite completely reworked. Add (timestamp) utility
functions for debugging and testing.
* erl_interface: Fix link error "multiple definition of
`ei_default_socket_callbacks'" for gcc version 10 or when built
with gcc option -fno-common. Error exists since OTP-21.3.
* asn1: Fix 'DEFAULT' with 'OCTET STRING' and 'SEQUENCE OF
CHOICE' with extensions.
* erts: gen_udp:recv(S, N, 0) corrupted the internal state for
the socket so after receive with {active, once} it always
returned {error, timeout}, and wasted the received UDP packets.
This bug has now been fixed. Reported and pinpointed by
Alexander Petrovsky.
* erts: The atom esock_atom_user and esock_atom_kernel was never
actually created. This has now been corrected.
* erts: Fixed bug in socket module that could potentially lead to
scheduler deadlocks.
* erts: Fix bug causing VM crash if down or stop callback of a
NIF resource is called after the NIF module has been purged.
The fix will postpone unloading until all such resource objects
have been garbage collected.
* erts: Fixed bug in ets:update_counter/4, when called with an
invalid UpdateOp and a Key that does not exist, causing
ets:info(T,size) to return incorrect values. Bug exists since
OTP-19.0.2.
* erts: Fix potential heap corrupting bugs when a process calls a
BIF that blocks other normal schedulers and then writes to its
own heap without the main process lock. A NIF running on a
dirty scheduler trying to interact with such a process could
corrupt its heap. The fixed BIFs were related to code loading
and tracing.
* erts: Fixed bug in erlang:list_to_ref/1 when called with a
reference created by a remote note. Function list_to_ref/1 is
intended for debugging and not to be used in application
programs. Bug exist since OTP 20.0.
* erts: The prim_net nif (net/kernel) made use of an undefined
atom, notsup. This has now been corrected.
* erts: Corrected the valid range of the erl command line
argument +SDio <NumberOfDirtyIoSchedulers> from 0..1024 to
1..1024. +SDio 0 was erroneously allowed which just caused the
VM to crash on the first dirty I/O job scheduled.
* erts: Fix a crash when attempting to log faults when loading
files during early boot.
* erts: For socket, not all send and receive flags are supported
on all platforms. In order to (at least) simplify testing, the
socket:supports/0,1,2,3 functions has been extended with
send_flags and recv_flags items, which indicates what the
current platform can manage.
* erts: Add a "full featured" version of getifaddrs in the net
module.
* erts: The options busy_limits_port and busy_limits_msgq have
been added to the BIF erlang:open_port/2. The busy_limits_port
option can be used for controlling the busy state of a port
executing the spawn_driver or the fd_driver. The
busy_limits_msgq option can be used for controlling the busy
state of the port message queue.
* erts: A socket "registry" has been added making it possible to
list current open sockets.
* erts: The counters managed by the socket nif has been extended.
Their "size" has been increased from 32 bit to 64. Two max
package size (for read and write) has been added. And four
accept counters has been added.
* erts: Add gcc option -fno-common to detect accidental name
clashes of global variables.
* erts: New dynamic lock checker that verifies locking orders and
detects potential deadlock bugs in drivers and NIFs. Enabled
together with the old static lock checker (for ERTS internal
locks) in emulator started with -emu_type debug or built with
configuration option --enable-lock-checking.
* snmp: A simple supervision of the snmp manager net-if process
has been added. Also, a way to forcibly restart the net-if
process has been added. This could be useful if the net-if
process hangs for some reason.
* snmp: Misc documentation corrections
* mnesia: Fixed a timing issue in uninstall fallback
functionality.
* eunit: Backport of PR-2316: Strip control codes from
eunit_surefire output to avoid generation of invalid xml
* ssh: Unicode problems for ssh_sftp:write fixed.
* ssh: Changes to the internal api of the experimental ssh_dbg
tool.
* ssh: The new functions ssh:set_sock_opts/2 and
ssh:get_sock_opts/2 sets and reads option values for the
underlying TCP stream.
* hipe: HiPE can again handle modules with catch and try
constructs.
* hipe: When the return value for try/catch was ignored, the
native code compiler could crash.
* public_key: Add support for key exchange with Edward curves and
PSS-RSA padding in signature verification.
* diameter: Add the 'first' tuple to type diameter:peer_filter/0.
The filter was added in OTP-17.5.6.8 and OTP-18.3, but neither
release updated the type specification.
* tools: An Emacs warning due to lacking type in defcustom
declaration has been fixed.
* tools: Improve emacs indentation.
* tools: The cover tool could generate instrumented code for a
module that would cause warnings to be issued.
* tools: Fixed generated fprof analysis format to also handle
data in maps.
* sasl: A socket "registry" has been added making it possible to
list current open sockets.
* kernel: The DNS resolver `inet_res` has been fixed to return
the last intermediate error when subsequent requests times out.
* kernel: The prim_net nif (net/kernel) made use of an undefined
atom, notsup. This has now been corrected.
* kernel: Fix a crash when attempting to log faults when loading
files during early boot.
* kernel: Fix crash in logger when logging to a remote node
during boot.
* kernel: Improved net_kernel debug functionality.
- Changes for 22.2.8:
* diameter: The possibility of choosing a handler process for an
incoming Diameter request with a configured MFA was documented
in OTP 20.0, but counters (with {traffic_counters, true}) were
not incremented when this process was on a remote node.
Counters are now incremented on the node that configures the
transport in question. Introduced in OTP 21.3.
* diameter: Transport options differing from those passed to
diameter:add_transport/2 were used in several situations: when
starting a transport process after connect_timer expiry after
an initial connection attempt has failed, when starting a
transport process after a connection has been accepted, when
sending events, when returning options in
diameter:service_info/2, and possibly more. In particular, the
following configuration options to diameter:add_transport/2
were dropped: avp_dictionaries, incoming_maxlen, spawn_opt,
strict_mbit. Moreover, any service options mistakenly passed to
diameter:add_transport/2 were interpreted as such, instead of
being ignored as the documentation states, with the consequence
that outgoing and incoming requests saw different values of
some options, some were always taken from transport options,
and others from service options. diameter:add_transport/2 must
be called in new code for the fix to have effect. Introduced in
OTP 20.1.

valid code that used the is_map_key/2 BIF.
* compiler: Fixed a bug that could cause the compiler to reject
valid code that matched the same map key several times.
* compiler: The compiler could crash when compiling a convoluted

- Changes for 22.2.5:
* erts: A process could end up in a state where it got
endlessly rescheduled without making any progress. This
occurred when a system task, such as check of process
code (part of a code purge), was scheduled on a high
priority process trying to execute on a dirty
scheduler.
* erts: Improved signal handling for processes executing dirty.
For example, avoid busy wait in dirty signal handler
process when process is doing garbage collection on
dirty scheduler.
* stdlib: A directory traversal vulnerability has been eliminated
in erl_tar. erl_tar will now refuse to extract symlinks
that points outside the targeted extraction directory
and will return {error,{Path,unsafe_symlink}}. (Thanks
to Eric Meadows-Jönsson for the bug report and for
suggesting a fix.)

- Changes for 22.2.4:
* ssl: Enhance error handling, all ALERTS shall be handled
gracefully and not cause a crash.
* ssl: Enhance alert logging, in some places the role
indication of the alert origin was missing. So the log
would say undefined instead of client or server.
* ssl: Two different optimizations did not work together and
resulted in the possible breakage of connections using
stream ciphers (that is RC4). Reworked the
implementation to avoid this.

when establishing TLS 1.3 connections. This change improves
handling of GREASE values in various protocol elements sent in
a TLS 1.3 ClientHello.
* ssl: Correct DTLS listen emulation, could cause problems with
opening a new DTLS listen socket for a port previously used by
a now closed DTLS listen socket.

- Changes for 22.2.2:
* erts: Taking a scheduler offline could cause timers set while
executing on that scheduler to be delayed until the scheduler
was put online again. This bug was introduced in ERTS version
10.0 (OTP 21.0).
* erts: The ets:update_counter/4 core dumped when given an
ordered_set with write_concurrency enabled and an invalid
position. This bug has been fixed.
* erts: A process calling erlang:system_flag(multi_scheduling,
block) could end up blocked waiting for the operation to
complete indefinitely.
* erts: Duplicate entries for [socket:]getopt and [socket:]setopt
in man page.
* stdlib: The ets:update_counter/4 core dumped when given an
ordered_set with write_concurrency enabled and an invalid
position. This bug has been fixed.
* crypto: Constant time comparisons added.
* ssh: Fixed that ssh_connection:send could allocate a large
amount of memory if given an iolist() as input data.
* ssh: Safe atom conversions.
* ssh: Constant time comparisons added.
- Changes for 22.2.1:
* erts: Corrected an issue with the new socket api which could
cause a core dump. A race during socket close could cause a
core dump (an invalid nif environment free).
* erts: Corrected an issue with the new socket api which could
cause a core dump. When multiple accept processes waiting for a
connect a connect could cause a core dump.

- Changes for 22.1.7
* http://erlang.org/download/OTP-22.1.7.README
* compiler: Fixed a performance bug that caused repeated matches of
large records to take a very long time to compile.
* erts: A literal area could prematurely be released before all
uses of it had been removed. This occurred either when
a terminating process had a complex exit reason
referring to a literal that concurrently was removed,
or when a terminating process continued executing a
dirty NIF accessing a literal (via the heap) that
concurrently was removed.
* erts: Fix bug causing VM crash due to memory corruption of
distribution entry. Probability of crash increases if
Erlang distribution is frequently disconnected and
reestablished towards same node names. Bug exists since
OTP-21.0.
* erts: Fixed bug causing crash of VM built with configuration
--enable--sharing-preserving. Provoked when a sent
message contains both a bit string and the heap binary
(< 65 bytes) which the bit string was matched from. Bug
exists since OTP-19.0 but has seen to be easier to
provoke since OTP-22.1.
- Changes for 22.1.6
* http://erlang.org/download/OTP-22.1.6.README
* compiler, erts: The compiler could do an unsafe optimization of
receives, which would cause a receive to only scan part
of the message queue.
* crypto: The AEAD tag was not previously checked on decrypt with
chacha20_poly1305
* erts:Fix bug where the receive marker used by the runtime to
do the receive queue optimization could be incorrectly
set. The symptom of this would be that a message that
should match in a receive never matches.
* snmp: Agent discovery cleanup. If there is no receiver of
INFORM then #state.reqs in snmpa_net_if keeps on
growing for DISCOVERY.

- Changes for 22.1.2:
* erts: Added the environment variable ERLC_SERVER_ID, which
allows multiple compile servers to run separately under the
same user.
- Changes for 22.1.1:

the erlang:port_*() BIFs one could sometimes get stray {Ref,
What} messages. Where Ref was a reference and What usually were
the atom badarg.
* snmp: Made it possible to add 'extra socket options' to the
(gen_udp) socket open call (for both manager and agent). A new
option has been added, extra_sock_opts, which makes it possible
for the user to add a list of extra socket options that will be
appended to the other socket options for the open call. See the
snmp application config man page (erl -man 6 snmp) or the
"Configuring the application" chapter of the Users Guide for
more info.
* compiler: Fixed a bug in the bit-syntax optimization pass that
could crash the compiler.

- Changes for 22.1:
* kernel: The type specification for gen_sctp:connect/4,5 has
been corrected.
* kernel: Extra -mode flags given to erl are ignored with a
warning.
* kernel: Fix type spec for seq_trace:set_token/2.
* kernel: logger:compare_levels/2 would fail with a badarg
exception if given the values all or none as any of the
parameters. This is now corrected.
* kernel: Fix bug where the log file in logger_std_h would not be
closed when the inode of the file changed. This would in turn
cause a file descriptor leak when tools like logrotate are
used.
* kernel: Fix a race condition in the debugging function
net_kernel:nodes_info/0.
* kernel: Fix race condition when closing a file opened in
compressed or delayed_write mode.
* kernel: The possibility to send ancillary data, in particular
the TOS field, has been added to gen_udp:send/4,5.
* kernel: If the log file was given with relative path, the
standard logger handler (logger_std_h) would store the file
name with relative path. If the current directory of the node
was later changed, a new file would be created relative the new
current directory, potentially failing with an enoent if the
new directory did not exist. This is now corrected and
logger_std_h always stores the log file name as an absolute
path, calculated from the current directory at the time of the
handler startup.
* kernel: Support local sockets with inet:i/0.
* observer: Fix bug after a user followed link on a pid from an
expanded term window.
* observer: Improved dark mode colors on Linux.
* mnesia: mnesia:add_table_copy/3 could cause a deadlock if
called when a new node was starting.
* mnesia: Transactions with sticky locks could with async_asym
transactions be committed in the wrong order, since asym
transaction are spawned on the remote nodes. To fix this bug
the communication protocol between mnesia nodes had to be
updated, thus mnesia will no longer be able to connect to nodes
earlier than mnesia-4.14 , OTP-19.0. *** POTENTIAL
INCOMPATIBILITY ***
* stdlib: re:run() now yields when validating utf8 in a large
subject.
* stdlib: Upgraded the ERTS internal PCRE library from version
8.42 to version 8.43. See
http://pcre.org/original/changelog.txt for information about
changes made to PCRE. This library implements major parts of
the re regular expressions module.
* stdlib: The bug with ID ERL-717 has been fixed. The functions
io:columns() and io:rows() only worked correctly inside
interactive erlang shells before this fix. These functions
returned {error,enotsup} before this fix even if stdout and
stdin were connected to a terminal when they were invoked from
an escript or a program started with e.g., erl -noshell.
* stdlib: Fixed handling of ".." and "@" in wildcards. ".." would
only work when preceded by a literal pattern such as in "a/..",
not when preceded by wildcard characters such as in "*/..". The
combination "@/.." was also broken, and in addition "@" in a
pattern could degrade performance of the wildcard matching.
* stdlib: Make sure ets:fun2ms() can handle ++/2 in the head of
functions when called from the shell.
* stdlib: Debugging of time-outs in gen_statem has been improved.
Starting a time-out is now logged in sys:log and sys:trace.
Running time-outs are visible in server crash logs, and with
sys:get_status. Due to this system events {start_timer, Action,
State} and {insert_timout, Event, State} have been added, which
may surprise tools that rely on the format of these events. New
features: The EventContent of a running time-out can be updated
with {TimeoutType, update, NewEventContent}. Running time-outs
can be cancelled with {TimeoutType, cancel} which is more
readable than using Time = infinity. *** POTENTIAL
INCOMPATIBILITY ***
* stdlib: re:run() now avoids validating utf8 in the subject more
than once in the same call. This validation could previously be
performed multiple times when the global option was passed.
* stdlib: ETS ordered_set tables with write_concurrency enabled
has got a performance issue fixed. There were no limits for the
values of internal statistics counters before this fix. This
could result in that the data structure sometimes reacted
slowly to a change in how many parallel processes were using
it.
* stdlib: The ordsets:union/1 is now faster when passed a long
list of ordsets.
* stdlib: unicode:characters_to_binary() could return very small
binaries as reference counted off heap binaries. This could
cause an unnecessary large memory usage and an unnecessary load
on the binary allocator. Small binaries are now always returned
as heap binaries.
* stdlib: Display a more meaningful error message when a bad I/O
server is used in a script written in Erlang (escript).
* stdlib: New feature ets:info(_, binary) to get information
about all reference counted binaries kept by a table. This is
the same kind of debug information that process_info(_, binary)
returns for a process.
* stdlib: Corrected ETS documentation about the behavior of
compiled match specifications when serialized through external
format.
* tools: cover would fail to start if two processes tried to
start it at the exact same time.
* common_test: If a ct hook is installed in the suite/0 function
in a test suite, then the hook's terminate/1 function would be
called several times without it's init/2 function being called
first. This is now corrected.
* common_test: If init_per_testcase fails, the test itself is
skipped. According to the documentation, it should be possible
to change the result to failed in a hook function. The only
available hook function in this case is post_init_per_testcase,
but changing the return value there did not affect the test
case result. This is now corrected.
* common_test: Add ct_netconfc support for NETCONF 1.1 (RFC
6241). The 1.1 base capability can be sent in hello, and RFC
6242 chunk framing is applied when both client and server
advertise 1.1 support.
* common_test: Correct lib_dir paths in common_tests opaque data
structure that is passed to ct_release_test callback modules in
functions upgrade_init/2, upgrade_upgraded/2 and
upgrade_downgraded/2. The incorrect paths may cause confusion
when debugging although it will not cause any incorrect
behavior on the part of common_test as it is currently not
used.
* erts: If you set {linger,{true,0}} on a gen_tcp listen socket,
accept a connection on that socket, and then close the accepted
socket, now the linger zero setting is transferred to the
accepted socket. Before this correction that information was
lost and the close behaviour on the accepted socket incorrect.
* erts: Sending ancillary data implemented in OTP-15747
accidentally left behind test code that caused all UDP sends to
fail on Windows. This has now been fixed.
* erts: In the socket nif, used invalid flags when if-def'ing for
supported TCP flags: TCP_MAXSEG and TCP_NODELAY (the support
function).
* erts: Fixed memory leaks in experimental socket module.
* erts: re:run() now yields when validating utf8 in a large
subject.
* erts: Fixed bug in seq_trace:set_token(label,Term) which could
cause VM crash if Term was heap allocated (not an atom, small
integer, local pid or port). Bug exists since OTP 21.0 when
terms other than small integers were first allowed as labels.
* erts: Extra -mode flags given to erl are ignored with a
warning.
* erts: Don't loop indefinitely when --enable-pgo is given to
configure, but compiler does not support pgo.
* erts: Fix seq_trace:print/2 not to raise badarg exception if
label is not a small integer. Bug exists since OTP 21.0.
* erts: Fixed hipe_flush_icache_range for non-Linux OS on ARM.
* erts: The fix in OTP-15871 was too conservative and disabled
the offending load-time optimization in some cases where it was
safe.
* erts: Upgraded the ERTS internal PCRE library from version 8.42
to version 8.43. See http://pcre.org/original/changelog.txt for
information about changes made to PCRE. This library implements
major parts of the re regular expressions module.
* erts: Fix race condition when closing a socket while using
{active,N} on Windows.
* erts: Allow more than one -config command line option to erl on
Windows to conform with other OS.
* erts: Fix so that ERL_FLAGS environment variable does not
interfere with command line arguments. Before this fix you
could write: ERL_FLAGS="10" erl +S and erlang would start as if
+S had been given the argument 10.
* erts: The bug with ID ERL-717 has been fixed. The functions
io:columns() and io:rows() only worked correctly inside
interactive erlang shells before this fix. These functions
returned {error,enotsup} before this fix even if stdout and
stdin were connected to a terminal when they were invoked from
an escript or a program started with e.g., erl -noshell.
* erts: Do not use named label in ethread.c inline assemble. This
allows erts to be compiled using gcc 9.1.0 with LTO enabled.
* erts: erlang:fun_to_list/1 will now escape the module and
function name when necessary.
* erts: process_info(P,binary) would neglect to look through heap
fragments, potentially missing a few binaries associated with
the process.
* erts: HiPE is now automatically disabled on systems with non-
glibc implementation (for instance musl). This is because musl
does not provide the API's for guaranteeing that signals are
delivered on the correct native stack.
* erts: Fixed bug triggered if a process is killed during call to
persistent_term:put or persistent_term:erase.
* erts: Add units to all memory slogans in the crash dump
documentation.
* erts: Fix a bug in binary_to_term that would crash the emulator
if a term larger than 16GB was to be decoded.
* erts: Fixed bug related to an exiting process sending EXIT and
DOWN signals to remote linked/monitored processes. Bugs exists
since OTP 22.0.
* erts: erlc can now automatically use a compile server to avoid
starting an Erlang system for each file to be compiled in a
multi-file project. See the documentation for how to enable it.
* erts: The possibility to send ancillary data, in particular the
TOS field, has been added to gen_udp:send/4,5.
* erts: The net module has been split into 'net' (kernel) and
prim_net (preloaded).
* erts: Socket counters now works as expected and can also be
extracted with the (new) info function.
* erts: re:run() now avoids validating utf8 in the subject more
than once in the same call. This validation could previously be
performed multiple times when the global option was passed.
* erts: The un-documented function erlang:dist_get_stat/1 now
returns the real value of what the distribution queue contains
instead of a boolean.
* erts: ETS ordered_set tables with write_concurrency enabled has
got a performance issue fixed. There were no limits for the
values of internal statistics counters before this fix. This
could result in that the data structure sometimes reacted
slowly to a change in how many parallel processes were using
it.
* erts: Optimize the reception of large distribution messages.
* erts: Binary matching and functions like split_binary/2 will
now create heap binaries when the results are small enough,
reducing the chances of small sub-binaries keeping large
binaries alive.
* erts: Fixed rare emulator crash in instrument:allocations/0-1.
* erts: Ports could pass very small binaries as reference counted
off heap binaries to processes. This could cause an unnecessary
large memory usage and an unnecessary load on the binary
allocator. Small binaries are now always passed as heap
binaries to processes.
* erts: unicode:characters_to_binary() could return very small
binaries as reference counted off heap binaries. This could
cause an unnecessary large memory usage and an unnecessary load
on the binary allocator. Small binaries are now always returned
as heap binaries.
* erts: Improved erl_nif documentation regarding on_load and
Erlang stub/fallback functions.
* erts: New feature ets:info(_, binary) to get information about
all reference counted binaries kept by a table. This is the
same kind of debug information that process_info(_, binary)
returns for a process.
* erl_docgen: Update the documentation build support to handle
FOP 2.1 .
* ftp: A possibly infinite loop when receiving messages divided
in parts is removed.
* dialyzer: Allow native compilation when using Dialyzer from
Erlang. The options native (defaults to false) and native_cache
have been added.
* eunit: Handle get_until request with explicit encoding in the
implementation of the I/O protocol.
* snmp: Fix various minor issues related to Dialyzer. Mostly
these are dialyzer warnings, but there was also some minor bugs
detected by Dialyzer.
* snmp: Fixed a dets usage problem detected by dialyzer.
* snmp: The function snmp:print_version_info() prints various
version info. For each module a number of items are printed,
such as app vsn and md5 digest. And an attempt was also made to
print "compile time". This used to be available in the
module_info for each module, but has now been removed.
* snmp: The use of the deprecated random module has been replaced
the with rand module.
* snmp: Removed use of the deprecated function
erlang:get_stacktrace(). Instead make use of the 'catch
Class:Error:Stacktrace' feature.
* syntax_tools: Add missing calls to erl_syntax:unwrap/1. The
nodes concerned represent names and values of maps and map
types.
* wx: Fix a driver bug that could crashes when allocating memory.
* erl_interface: Fix bugs in ei_print_term for binaries and bit
strings causing incorrect output.
* erl_interface: Fixed bug in ei_decode_fun for very old fun
encoding format. Bug exist since OTP 22.0.
* erl_interface: ei_print_term() now supports printing of maps
and funs.
* xmerl: xmerl_sax_parser crashed during charset detection when
the xml declarations attribute values was missing the closing
quotation (' or ").
* ssl: Handling of zero size fragments in TLS could cause an
infinite loop. This has now been corrected.
* ssl: DTLS record check needs to consider that a resent hello
message can have a different version than the negotiated.
* ssl: Basic support for TLS 1.3 Client for experimental use. For
more information see the Standards Compliance chapter of the
User's Guide.
* ssl: Correct solution for retaining tcp flow control OTP-15802
(ERL-934) as to not break ssl:recv as reported in (ERL-938)
* ssl: Enhance dialyzer specs to reflect implementation better
and avoid dialyzer warnings for the user that wants to use TLS
with unix domain sockets.
* ssl: Add support for ECDSA signature algorithms in TLS 1.3.
* ssl: Correct error handling of TLS downgrade, possible return
values form ssl:close/2 when downgrading is {ok, Port} or
{error, Reason}, it could happen that only ok was returned
instead of {error, closed} when downgrade failed due to that
the peer closed the TCP connection.
* os_mon: Fix disk_sup to ignore squashfs on Linux when
determining if a mounted filesystem is full or not.
* os_mon: Fix bug where cpu_sup:util() always returned 100% on
systems not using gnu libc, for example Alpine OS.
* ssh: Fixed wrong type definition for the daemon option
subsystems.
* ssh: Fixed a possible SSH logging crash if there was a problem
in an early stage of session setup.
* ssh: The documentation for the modules ssh_connection, ssh_sftp
and ssh_sftpd are now generated from the -spec:s.
* ssh: Internal cleanup including removal of the internal file
ssh_userauth.hrl.
* ssh: Removed unused definitions in ssh.hrl.
* ssh: Removed unused fields in the internal #connection{}
record.
* ssh: To get information of a connection_ref() from for example
ssh:connect/3, there was previously one function available
namely ssh:connection_info/2. This ticket adds
ssh:connection_info/1 which returns all information. For
daemons (servers) started with for example ssh:daemon/2 the
function ssh:daemon_info/1 returning all information was
available. This ticket adds ssh:daemon_info/2 which returns
only the information specified in the second argument. The info
of connections and of daemons now also includes the item
'options'. Only those options that does not have their default
values are returned. For a connection also the items
'algorithms' and 'channels' are added.
* inets: httpd - Accept singel LF as line terminator
* inets: mod_esi will now always propagate the actual HTTP status
code that it answered with, to later mod-modules, and not in
some cases hardcode 200.
* compiler: Code such as the following would crash the compiler
in OTP 22: [some_atom = fun some_function/1]
* compiler: Compilation could get really slow (in the order of
minutes instead of seconds) when compiling huge functions.
(Thanks to Kostis Sagonas for reporting this bug.)
* compiler: Fixed a bug in the validator that could reject valid
code.
* compiler: In rare circumstances, when two clauses had identical
bodies and guard tests that tested a single boolean variable,
the guard test for the second clause could be discarded,
executing the second clause unconditionally if the first clause
was not executed.
* compiler: Fixed extremely slow compilation for huge functions
doing predominantly pattern matching.
* compiler: The compiler could generate unsafe code (that would
crash the runtime system) for map pattern matching. The code
could be unsafe if the matched key was not present in the map
at runtime.
* compiler: Correct code using try/after could fail to compile
when using the option 'no_type_opt'.
* compiler: The compiler could crash when compiling code that
called 'length/1' on a binary extracted using the binary
syntax.
* compiler: Fixed a bug where the compiler could fail with an
internal consistency failure error when compiling receive
statements.
* compiler: Fixed a problem where the compiler would crash when
compiling binary matching in a function head.
* public_key: Support Password based encryption with AES
* public_key: Change dialyzer spec to avoid confusion
* runtime_tools: Fix dbg:stop_clear/0 to also clear trace events
(send and 'receive').
* megaco: Fix various minor issues related to Dialyzer. Mostly
these are dialyzer warnings, but there was also some minor bugs
detected by Dialyzer.
* crypto: The implementation of crypto_one_time/4 is adjusted to
match the type specification. The spec and the black-box
behaviour of the function are unchanged. Some details: Both the
spec and the implementation were correct seen separately. But
with both of them combined simultaneously with
crypto_one_time/5 which was called by the implementation of
crypto_one_time/4, an (obvious) error was detected by a
Dialyzer with more thorough checking than usual.
* crypto: When using crypto with FIPS mode enabled, the digests
were not correctly handled.
* crypto: A memory leak in error handling code in
ng_crypto_init_nif is fixed.
* crypto: Fixed the broken static build of the crypto nifs
* crypto: The Message Authentication Codes (MAC) CMAC, HMAC and
Poly1305 are unified into common functions in the New Crypto
API. See the manual for CRYPTO.
* sasl: The net module has been split into 'net' (kernel) and
prim_net (preloaded).
* jinterface: Replaced deprecated <tt> with <code> in
documentation.
