--- HIGHLIGHTS ----------------------------------------------------------
OTP-8217 == erts stdlib compiler ==
The module binary from EEP31 (and EEP9) is implemented.
OTP-8485 == common_test ==
It is now possible for the user to provide specific callback
modules that handle test configuration data, so that data on
arbitray form can be accessed (e.g. by reading files or by
communicating with a configuration server process). Two
default callback modules have been introduced in Common Test:
ct_config_plain and ct_config_xml. The former is used to
handle the traditional Common Test configuration files (with
terms on key-value tuple form) and the latter to handle
configuration data on XML representation.
OTP-8555 == erts ==
New NIF features:
Send messages from a NIF, or from thread created by NIF, to
any local process (enif_send)
Store terms between NIF calls (enif_alloc_env,
enif_make_copy)
Create binary terms with user defined memory management
(enif_make_resource_binary)
And some incompatible changes made to the API. For more
information see the warning text in erl_nif(3).
OTP-8623 == compiler erts hipe stdlib ==
Receive statements that can only read out a newly created
reference are now specially optimized so that it will execute
in constant time regardless of the number of messages in the
receive queue for the process. That optimization will benefit
calls to gen_server:call(). (See gen:do_call/4 for an example
of a receive statement that will be optimized.)
OTP-8650 == common_test ==
The run_test script has been replaced by a program (with the
same name) which can be executed without explicit
installation. The start flags are the same as for the legacy
start script.
OTP-8706 == erts hipe tools ==
eprof has been reimplemented with support in the Erlang
virtual machine and is now both faster (i.e. slows down the
code being measured less) and scales much better. In
measurements we saw speed-ups compared to the old eprof
ranging from 6 times (for sequential code that only uses one
scheduler/core) up to 84 times (for parallel code that uses 8
cores).
Note: The API for the eprof has been cleaned up and extended.
See the documentation.
--- documentation -------------------------------------------------------
OTP-8477 The guard BIF is_boolean/1 (introduced in R10B) has now been
included in the lists of BIFs allowed in guards in the
Reference Manual.
OTP-8559 If the 'fop' program (needed for building PDF files) cannot
not be found, it is now possible to build the HTML and man
pages anyway (there will also be dummy PDF files with no real
content created). (Thanks to Tuncer Ayaz.)
--- otp -----------------------------------------------------------------
OTP-8512 The INSTALL.md, INSTALL-CROSS.md, and INSTALL-WIN32.md
"readme files" are now included in both the HTML and the PDF
documentation.
OTP-8541 Added cross configuration file for mips-linux. (Thanks to
Matthias Lang for the configuration)
--- appmon-2.1.12 -------------------------------------------------------
OTP-8674 Warnings due to new autoimported BIFs removed
--- asn1-1.6.14 ---------------------------------------------------------
OTP-8565 By default, the ASN.1 compiler is now silent in the absence
of warnings or errors. The new 'verbose' option or the '-v'
option for erlc can be given to show extra information (for
instance, about the files that are generated). (Thanks to
Tuncer Ayaz.)
--- common_test-1.5 -----------------------------------------------------
OTP-8485 It is now possible for the user to provide specific callback
modules that handle test configuration data, so that data on
arbitray form can be accessed (e.g. by reading files or by
communicating with a configuration server process). Two
default callback modules have been introduced in Common Test:
ct_config_plain and ct_config_xml. The former is used to
handle the traditional Common Test configuration files (with
terms on key-value tuple form) and the latter to handle
configuration data on XML representation.
OTP-8490 It is now possible to execute test suites that are not
necessarily available on the local file system, but have been
loaded on the test node in advance (e.g. sent as binaries
from a remote node and loaded by RPC). A requirement is that
the no_auto_compile (or {auto_compile,false}) parameter has
been set.
OTP-8500 Test Server will now call the end_per_testcase/2 function
even if the test case has been terminated explicitly (with
abort_current_testcase/1), or after a timetrap timeout. Under
these circumstances the return value of end_per_testcase is
completely ignored. Therefore the function will not be able
to change the reason for test case termination by returning
{fail,Reason}, nor will it be able to save data with
{save_config,Data}.
OTP-8570 It is now possible to use the test specification term 'init'
to start Common Test nodes automatically, as well as have
initial function calls evaluated on the nodes. A default
callback module for the 'init' term, ct_slave, has been
introduced to enable Common Test Master to perform host login
and node startup operations over ssh.
OTP-8621 Process calls using monitors in Common Test would not clear
the inbox of remaining DOWN messages. This has been fixed.
OTP-8650 The run_test script has been replaced by a program (with the
same name) which can be executed without explicit
installation. The start flags are the same as for the legacy
start script.
OTP-8689 Previously, a repeat property of a test case group specified
the number of times the group should be repeated after the
main test run. I.e. {repeat,N} would case the group to
execute 1+N times. To be consistent with the behaviour of the
run_test repeat option, this has been changed. N now
specifies the absolute number of executions instead.
OTP-8690 With the run_test -erl_args option, it's possible to divide
the options on the run_test command line into ones that
Common Test should process (those preceding -erl_args, and
ones it should ignore (those succeeding -erl_args). Options
preceding -erl_args that Common Test doesn't recognize are
also ignored (i.e. the same behaviour as earlier versions of
Common Test).
OTP-8691 Directories added with -pa or -pz in the pre-erl_args part of
the run_test command line will be converted from relative to
absolute, this to avoid problems loading user modules when
Common Test switches working directory during the test run.
OTP-8693 The timetrap handling has been made more user controllable by
means of new start options and new ct interface functions.
With the 'multiply_timetraps' start option, it's possible to
specify a value which all timetrap timeout values get
multiplied by. This is useful e.g. to extend the timetraps
temporarily while running cover or trace. The
'scale_timetraps' start option switches on or off the Test
Server timetrap scaling feature (which tries to detect if the
tests may benefit from extended timetraps, e.g. due to
running certain test tools, and performs the scaling
automatically). Furthermore, the ct:timetrap/1 function has
been introduced, which makes it possible to set/reset
timetraps during test execution. Also, a ct:sleep/1 function
is now available, which takes the timetrap parameters into
account when calculating the time to suspend the process.
OTP-8694 A new run_test start option, event_handler_init, has been
added that takes a start argument which gets passed to the
init function of the event handler.
--- compiler-4.7 --------------------------------------------------------
OTP-8217 The module binary from EEP31 (and EEP9) is implemented.
OTP-8552 Several problems in the inliner have been fixed.
OTP-8579 Local and imported functions now override the auto-imported
BIFs when the names clash. The pre R14 behaviour was that
auto-imported BIFs would override local functions. To avoid
that old programs change behaviour, the following will
generate an error:
* Doing a call without explicit module name to a local function
having a name clashing with the name of an auto-imported BIF
that was present (and auto-imported) before OTP R14A
* Explicitly importing a function having a name clashing with
the name of an autoimported BIF that was present (and
autoimported) before OTP R14A
* Using any form of the old compiler directive nowarn_bif_clash
If the BIF was added or auto-imported in OTP R14A or later,
overriding it with an import or a local function will only
result in a warning,
To resolve clashes, you can either use the explicit module
name erlang to call the BIF, or you can remove the
auto-import of that specific BIF by using the new compiler
directive -compile({no_auto_import,[F/A]})., which makes all
calls to the local or imported function without explicit
module name pass without warnings or errors.
The change makes it possible to add auto-imported BIFs
without breaking or silently changing old code in the future.
However some current code ingeniously utilizing the old
behaviour or the nowarn_bif_clash compiler directive, might
need changing to be accepted by the compiler.
OTP-8584 The undocumented, unsupport, and deprecated function
lists:flat_length/1 has been removed.
OTP-8597 Nested records can now be accessed without parenthesis. See
the Reference Manual for examples. (Thanks to YAMASHINA Hio
and Tuncer Ayaz.)
OTP-8602 It is now possible to suppress the warning in code such as
"list_to_integer(S), ok" by assigning the ignored value "_"
like this: "_ = list_to_integer(S), ok".
OTP-8623 receive statements that can only read out a newly created
reference are now specially optimized so that it will execute
in constant time regardless of the number of messages in the
receive queue for the process. That optimization will benefit
calls to gen_server:call(). (See gen:do_call/4 for an example
of a receive statement that will be optimized.)
OTP-8668 The compiler optimizes record operations better.

--- crypto-2.0 ----------------------------------------------------------
OTP-8333 crypto application changed to use NIFs instead of driver.
OTP-8551 des_ecb_encrypt/2 and des_ecb_decrypt/2 has been added to the
crypto module. The crypto:md4/1 function has been documented.
OTP-8584 The undocumented, unsupport, and deprecated function
lists:flat_length/1 has been removed.
OTP-8700 New variants of crypto:dss_sign and crypto:dss_verify with an
extra argument to control how the digest is calculated.
--- debugger-3.2.3 ------------------------------------------------------
OTP-8674 Warnings due to new autoimported BIFs removed
OTP-8687 The predefined builtin type tid() has been removed. Instead,
ets:tid() should be used.
--- dialyzer-2.3.0 ------------------------------------------------------
OTP-8699 Various changes to dialyzer-related files for R14.
- Dialyzer properly supports the new attribute -export_type
and checks that remote types only refer to exported types. A
warning is produced if some files/applications refer to types
defined in modules which are neither in the PLT nor in the
analyzed applications.
- Support for detecting data races involving whereis/1 and
unregister/1.
- More precise identification of the reason(s) why a record
construction violates the types declared for its fields.
- Fixed bug in the handling of the 'or' guard.
- Better handling of the erlang:element/2 BIF.
- Complete handling of Erlang BIFs.
--- erl_interface-3.7 ---------------------------------------------------
OTP-8684 compact IEEE 754 double encoding in external binary format
for ei
Implement the compact IEEE 754 double encoding in external
binary format for ei. Encoding for ei now always produces the
NEW_FLOAT_EXT format. Decoding and term printing handle both
the old ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT
encoding.
Legacy erl_interface code also handles the new encoding, but
still produces the ERL_FLOAT_EXT encoding by default.
Also enable the DFLAG_NEW_FLOATS distribution flag.
ei_get_type() will return ERL_FLOAT_EXT regardless if the
external format is encoded with ERL_FLOAT_EXT or
NEW_FLOAT_EXT for doubles.
Reduce the number of copies of the code for encoding and
decoding doubles throughout ei and erl_interface by instead
calling the ei encoding and decoding functions wherever
possible.
Restore commented-out float tests in ei_decode_SUITE and
ei_encode_SUITE in lib/erl_interface/test. Modify them to
make them match the style of other tests in the same suites.
These changes are based on an ei float patch from Serge
Aleynikov originally submitted against R12B-2 in July 2008
and reworked by Steve Vinoski May 2010.
--- erts-5.7.5.1 --------------------------------------------------------
OTP-8475 Driver threads, such as async threads, using port data locks
peeked at the port status field without proper locking when
looking up the driver queue.
OTP-8487 A call to the BIF unregister(RegName) when a port had the
name RegName registered in the runtime system without SMP
support caused a runtime system crash. (Thanks to Per Hedeland
for the bugfix and test case.)
OTP-8591 Fix memory management bug causing crash of non-SMP emulator
with async threads enabled. The bug did first appear in
R13B03.
--- erts-5.8 ------------------------------------------------------------
OTP-8086 The grammar for match specifications in ERTS users guide only
described the tracing dialect of match specifications. An
informal grammar for the ETS dialect is added.
OTP-8217 The module binary from EEP31 (and EEP9) is implemented.
OTP-8474 New NIF API function enif_make_new_binary
OTP-8477 The guard BIF is_boolean/1 (introduced in R10B) has now been
included in the lists of BIFs allowed in guards in the
Reference Manual.
OTP-8484 The use of mmap() was unnecessarily disabled when cross
compiling.
The configure arguments --with-ssl, and --with-odbc refused
to accept libraries outside of $erl_xcomp_sysroot when cross
compiling for no good reason.
The configure argument --with-odbc didn't handle the value
yes correct.
The configure arguments --with-odbc, and --without-odbc have
also been added to the configure help.
(Thanks to Steve Vinoski for reporting these issues)
OTP-8521 Added function zip:foldl/3 to iterate over zip archives.
Added functions to create and extract escripts. See
escript:create/2 and escript:extract/2.
The undocumented function escript:foldl/3 has been removed.
The same functionality can be achieved with the more flexible
functions escript:extract/2 and zip:foldl/3.
Record fields has been annotated with type info. Source files
as been adapted to fit within 80 chars and trailing
whitespace has been removed.
OTP-8539 A regular expression with many levels of parenthesis could
cause a buffer overflow. That has been corrected. (Thanks to
Michael Santos.)
OTP-8548 erlang:decode_packet(httph_bin,..) could return corrupt
header strings or even crash the VM. This has been fixed. It
only happened on 32-bit VM if the header name was unknown and
between 16 and 20 characters long. Sockets with simular
packet option did not suffer from this bug.
OTP-8549 The runtime system crashed if fewer logical processors were
found than reported by sysconf( SC_NPROCESSORS_CONF).
OTP-8555 New NIF features:
Send messages from a NIF, or from thread created by NIF, to
any local process (enif_send)
Store terms between NIF calls (enif_alloc_env,
enif_make_copy)
Create binary terms with user defined memory management
(enif_make_resource_binary)
And some incompatible changes made to the API. For more
information see the warning text in erl_nif(3).
OTP-8559 If the 'fop' program (needed for building PDF files) cannot
not be found, it is now possible to build the HTML and man
pages anyway (there will also be dummy PDF files with no real
content created). (Thanks to Tuncer Ayaz.)
OTP-8562 When defining macros the closing right parenthesis before the
dot is now mandatory.
OTP-8579 Local and imported functions now override the auto-imported
BIFs when the names clash. The pre R14 behaviour was that
auto-imported BIFs would override local functions. To avoid
that old programs change behaviour, the following will
generate an error:
Doing a call without explicit module name to a local function
having a name clashing with the name of an auto-imported BIF
that was present (and auto-imported) before OTP R14A
Explicitly importing a function having a name clashing with
the name of an autoimported BIF that was present (and
autoimported) before OTP R14A
Using any form of the old compiler directive nowarn_bif_clash
If the BIF was added or auto-imported in OTP R14A or later,
overriding it with an import or a local function will only
result in a warning,
To resolve clashes, you can either use the explicit module
name erlang to call the BIF, or you can remove the
auto-import of that specific BIF by using the new compiler
directive -compile({no_auto_import,[F/A]})., which makes all
calls to the local or imported function without explicit
module name pass without warnings or errors.
The change makes it possible to add auto-imported BIFs
without breaking or silently changing old code in the future.
However some current code ingeniously utilizing the old
behaviour or the nowarn_bif_clash compiler directive, might
need changing to be accepted by the compiler.
OTP-8589 A bug in re that could cause certain regular expression
matches never to terminate is corrected. (Thanks to Michael
Santos and Gordon Guthrie.)
OTP-8612 Port locks could be prematurely destroyed.
OTP-8614 The erlang:open_port spawn and spawn_executable directives
can include an {env,Env} directive to set up environment
variables for the spawned process. A bug prevented
applications from using {env,Env} to set an environment
variable whose value ended with a '=' (equal sign) character;
the trailing equal sign was mistaken as an indication that an
environment variable was to be cleared from the environment
of the spawned process. (Thanks to Steve Vinoski.)
OTP-8618 The empd program could loop and consume 100% CPU time if an
unexpected error ocurred in listen() or accept(). Now epmd
will terminate if a non-recoverable error occurs. (Thanks to
Michael Santos.)
OTP-8623 receive statements that can only read out a newly created
reference are now specially optimized so that it will execute
in constant time regardless of the number of messages in the
receive queue for the process. That optimization will benefit
calls to gen_server:call(). (See gen:do_call/4 for an example
of a receive statement that will be optimized.)
OTP-8632 When kernel poll has been enabled, a livelock could in rare
circumstances occur. Problem reported by Chetan Ahuja, fix by
Mikael Pettersson.
OTP-8637 The functions file:advise/4 and file:datasync/1 have been
added. (Thanks to Filipe David Manana.)
OTP-8640 New NIF API functions: enif_make_atom_len,
enif_make_existing_atom_len, enif_make_string_len,
enif_get_atom_length, enif_get_list_length, enif_is_list,
enif_is_tuple (by Tuncer Ayaz)
OTP-8641 Windows: Closing port of program that stalled without reading
all data could deadlock scheduler thread.
OTP-8654 On some combination of Montavista Linux on Cavium Octeon
processors, some socket-related system calls returned other
numbers than -1 for errors. This caused a core dump in
inet_drv.c. Now the code works around this problem.
OTP-8658 Missing memory barriers in erts_poll() could cause the
runtime system to hang indefinitely.
OTP-8659 Support for using gcc's built-in functions for atomic memory
access has been added. This functionallity will be used if
available and no other native atomic implementation in ERTS
is available.
OTP-8660 The number of spinlocks used when implementing atomic
fall-backs when no native atomic implementation is available
has been increased from 16 to 1024.
OTP-8661 Writer preferred pthread read/write locks has been enabled on
Linux.
OTP-8662 ethr_rwmutex_tryrlock() acquired and refused to acquire a
lock with inverted logic. The lock was however never acquired
in a thread unsafe manner. (Thanks to JR Zhang for noting
this issue)
OTP-8663 Extreme combinations of register/unregister in a highly
parallell SMP application could crash the VM. The error is
corrected.
OTP-8666 The runtime system will by default bind schedulers to logical
processors using the default_bind bind type if the amount of
schedulers are at least equal to the amount of logical
processors configured, binding of schedulers is supported,
and a CPU topology is available at startup.
NOTE: If the Erlang runtime system is the only operating
system process that binds threads to logical processors, this
improves the performance of the runtime system. However, if
other operating system processes (as for example another
Erlang runtime system) also bind threads to logical
processors, there might be a performance penalty instead. If
this is the case you, are are advised to unbind the
schedulers using the +sbtu command line argument, or by
invoking erlang:system_flag(scheduler_bind_type, unbound).
OTP-8667 On Windows, files are now opened with FILE_SHARE_DELETE to
get closer to Unix semantics.
OTP-8669 The recently added BIFs erlang:min/2, erlang:max/2 and
erlang:port_command/3 are now auto-imported (as they were
originally intended to be). Due to the recent compiler change
(OTP-8579), the only impact on old code defining it's own
min/2, max/2 or port_command/3 functions will be a warning,
the local functions will still be used. The warning can be
removed by using
-compile({no_auto_import,[min/2,max/2,port_command/3]}). in
the source file.
OTP-8670 There is a new option 'exclusive' to file:open/2 that uses
the OS O_EXCL flag where supported to open the file in
exclusive mode.
OTP-8671 Now, binary_to_term/2 is auto-imported. This will cause a
compile warning if and only if a module has got a local
function with that name.
OTP-8673 Alignment of scheduler data and run queues were adjusted.
OTP-8675 erlang:system_info(multi_scheduling) sometimes erroneously
returned enabled when it should have returned blocked.
OTP-8677 Call time breakpoint tracing Introduce a call_time option to
erlang:trace_pattern/3.This option enables call time
breakpoint tracing on code that is executed by processes with
call tracing enabled. Call time tracing stores the number of
calls and the time spent of each function with this trace
pattern enabled. The information can be retrieved with
erlang:trace_info/2 Add a scheduler array for BpData. To
solve the issue of multiple schedulers constantly updating
the head pointer to the bp data wheel, each scheduler now has
its own entrypoint to the wheel. This head pointer can be
updated without a locking being taken.
Teach call count tracing to use atomics Call count previously
used a global lock for accessing and writing its counter in
the breakpoint. This is now changed to atomics instead. The
change will let call count tracing and cprof to scale better
when increasing the number of schedulers.
OTP-8685 Fix bug causing erlang:decode_packet and enif_make_string to
generate faulty strings with negative character values for
ascii values larger than 127. (Thanks to Paul Guyot)
OTP-8701 open_port/2 with the spawn and spawn_executable options can
include an {env,Env} option. In some cases unsetting
variables would not work on Unix (typically if more variables
were unset than were actually present in the environment).
OTP-8706 eprof has been reimplemented with support in the Erlang
virtual machine and is now both faster (i.e. slows down the
code being measured less) and scales much better. In
measurements we saw speed-ups compared to the old eprof
ranging from 6 times (for sequential code that only uses one
scheduler/core) up to 84 times (for parallel code that uses 8
cores).
Note: The API for the eprof has been cleaned up and extended.
See the documentation.

OTP-8623 receive statements that can only read out a newly created

--- ic-4.2.25 -----------------------------------------------------------
OTP-8639 The documentation can now be built and installed without
Java.
--- inets-5.3.1 ---------------------------------------------------------
OTP-8508 [httpc] Badly formated error reason for errors occuring
during initial connec to a servert. Also, the possible error
reasons was not properly documented.
OTP-8509 [httpd] Issues with ESI erl_script_timeout. *) The
"erl_script_timeout" config option is ducumented as a number
of seconds. But when parsing the config, in the new format
(not a config file), it was handled as if in number of
milliseconds. *) When the erl-script-timeout time was
exceeded, the server incorrectly marked the answer as sent,
thereby leaving client hanging (with an incomplete answer).
This has been changed, so that now the socket will be closed.
--- inets-5.3.2 ---------------------------------------------------------
OTP-8542 [httpc] Memory leak plugged. The profile manager never cleaned
up in its handler database. This meant that with each new
request handler, another entry was created that was never
deleted. Eventually the request id counter (used as a key)
would wrap, but the machine would most likely run out of
memory before that happened.
OTP-8607 [httpc] https requests with default port not handled properly.
Jebu Ittiachen.
--- inets-5.3.3 ---------------------------------------------------------
OTP-8609 [httpc] Made cookie handling more case insensitive.
OTP-8610 [httpc|httpd] Some netscape cookie dates are given with
a 2-digit year (e.g. 06 = 2006).
OTP-8624 [httpd] Added support (again) for the documented debugging
features. See the User's Guide Configuration chapter for
more info.
--- inets-5.4 -----------------------------------------------------------
OTP-7907 [httpc|httpd] - Now allow the use of the "new" ssl, by using
the essl tag instead. See the http_option option in the
httpc:request/4,5 or the socket-type section of the
Communication properties chapter for more info.
OTP-8564 Deprecated functions designated to be removed in R14 has been
removed. Also, some new functions has been marked as
deprecated (the old http client api module).
OTP-8573 [httpd] Improved mod_alias. Now able to do better URL
rewrites.
--- kernel-2.13.5.1 -----------------------------------------------------
OTP-8502 A race condition in os:cmd/1 could cause the caller to
get stuck in os:cmd/1 forever.
OTP-8506 Use an infinity timeout in all calls to
gen_server:call() in the sasl application.

OTP-3626 os:find_executable can now be fed with the complete name of
the executable on Windows and still find it. I.e
os:find_executable("werl.exe") will work as
os:find_executable("werl").
OTP-8527 As of this version, the global name server no longer supports
nodes running Erlang/OTP R11B.
OTP-8611 The file module's functions write,read and read_line now
handles named io_servers like 'standard_io' and
'standard_error' correctly.
OTP-8635 The shell's line editing has been improved to more resemble
the behaviour of readline and other shells. (Thanks to Dave
Peticolas)
OTP-8637 The functions file:advise/4 and file:datasync/1 have been
added. (Thanks to Filipe David Manana.)
OTP-8643 Under certain circumstances the net kernel could hang.
(Thanks to Scott Lystig Fritchie.)
OTP-8652 The kernel DNS resolver was leaking one or two ports if the
DNS reply could not be parsed or if the resolver(s) caused
noconnection type errors. Bug now fixed. A DNS specification
borderline truncated reply triggering the port leakage bug
has also been fixed.
OTP-8653 When exchanging groups between nodes pg2 did not remove
duplicated members. This bug was introduced in R13B03
(kernel-2.13.4).
OTP-8670 There is a new option 'exclusive' to file:open/2 that uses
the OS O_EXCL flag where supported to open the file in
exclusive mode.
OTP-8686 A bug introduced in kernel-2.13.5.3 has been fixed.
--- megaco-3.14.1 -------------------------------------------------------
OTP-8561 A minor compiler related performance improvement.
OTP-8529 A raise condition when, during high load, processing both
the original and a resent message and delivering this as
two separate messages to the user. Note that this solution
only protects against multiple reply deliveries!
OTP-8627 Fix shared libraries installation. The flex shared lib(s)
were incorrectly installed as data files.
OTP-8634 Eliminated a possible raise condition while creating pending
counters.
--- megaco-3.14.1.1 -----------------------------------------------------
OTP-8696 Performance chapter updated
--- mnesia-4.4.14 -------------------------------------------------------
OTP-8519 Added mnesia:subscribe(activity) contributed by Bernard
Duggan.
--- observer-0.9.8.3 ----------------------------------------------------
OTP-8708 The test suite has been updated for R14A.
--- odbc-2.10.8 ---------------------------------------------------------
OTP-7452 ODBC now handles the types SQL_WCHAR and SQL_WVARCHAR. Thanks
to Juhani Ränkimies. ODBC also has a new connection option to
return all strings as binaries and also expect strings to be
binaries in the param_query function. These changes provides
some unicode support.
OTP-8484 The use of mmap() was unnecessarily disabled when cross
compiling.
The configure arguments --with-ssl, and --with-odbc refused
to accept libraries outside of $erl_xcomp_sysroot when cross
compiling for no good reason.
The configure argument --with-odbc didn't handle the value
yes correct.
The configure arguments --with-odbc, and --without-odbc have
also been added to the configure help.
(Thanks to Steve Vinoski for reporting these issues)
OTP-8511 Now supports SQL_TYPE_TIMESTAMP on the format {{YY, MM, DD},
{HH, MM, SS}}. Thanks to Juhani Ränkimies.
--- orber-3.6.16 --------------------------------------------------------
OTP-8489 Added missing trailing bracket to define in hrl-file.
OTP-8543 Test suites published.
--- parsetools-2.0.3 ----------------------------------------------------
OTP-8483 Yecc failed to report reduce/reduce conflicts where one of
the reductions involved the root symbol. This bug has been
fixed. (Thanks to Manolis Papadakis.)
OTP-8486 A bug introduced in Parsetools 1.4.4 (R12B-2) has been fixed.
(Thanks to Manolis Papadakis.)
--- public_key-0.6 ------------------------------------------------------
OTP-7046 Support for Diffie-Hellman. ssl-3.11 requires public_key-0.6.
OTP-8553 Moved extended key usage test for ssl values to ssl.
OTP-8557 Fixes handling of the option fail_if_no_peer_cert and some
undocumented options. Thanks to Rory Byrne.
OTP-7046 Support for Diffie-Hellman. ssl-3.11 requires public_key-0.6.
OTP-8517 New ssl now properly handles ssl renegotiation, and initiates
a renegotiation if ssl/ltls-sequence numbers comes close
to the max value. However RFC-5746 is not yet supported,
but will be in an upcoming release.
OTP-8545 When gen_tcp is configured with the {packet,http} option,
it automatically switches to expect HTTP Headers after a
HTTP Request/Response line has been received. This update
fixes ssl to behave in the same way. Thanks to Rory Byrne.
OTP-8554 Ssl now correctly verifies the extended_key_usage extension
and also allows the user to verify application specific
extensions by supplying an appropriate fun.
OTP-8560 Fixed ssl:transport_accept/2 to return properly when socket
is closed. Thanks to Rory Byrne.
--- public_key-0.7 ------------------------------------------------------
OTP-8626 Certificates without any extensions could not be handled by
public_key.
OTP-8649 Code cleanup and minor bugfixes.
--- reltool-0.5.4 -------------------------------------------------------
OTP-8521 Added function zip:foldl/3 to iterate over zip archives.
Added functions to create and extract escripts. See
escript:create/2 and escript:extract/2.
The undocumented function escript:foldl/3 has been removed.
The same functionality can be achieved with the more flexible
functions escript:extract/2 and zip:foldl/3.
Record fields has been annotated with type info. Source files
as been adapted to fit within 80 chars and trailing
whitespace has been removed.
OTP-8590 A new escript, called reltool, has been introduced in order
to simplify the usage of the reltool application from
makefiles.
The handling of applications included in releases has been
improved. Applications that are required to be started before
other applications in a release are now automatically
included in the release. The kernel and stdlib applications
are always included as they are mandatory.
Applications that are (explicitly or implicitly) included in
a release are now automatically included as if they were
explicitly included with the incl_cond flag.
A new embedded_app_type option has been introduced. It is
intended to be used for embedded systems where all included
applications must be loaded from the boot script, as these
systems does not utilize dynamic code loading. If
embedded_app_type is set to something else than undefined,
all included applications will be included in both the
release as well as in the boot script. If the profile is
embedded the embedded_app_type option defaults to load.
A new function called reltool:get_status/1 has been
introduced. It returns status about the configuration in the
server.
The API functions that may take PidOrOptions as input and
actually gets Options does now print out warnings.
The internal error handling has been improved. For example
{error,Reason} is always returned in case of errors even when
the server dies.
app and appup files has been added as well as a corresponding
test suite.
Various cleanups has been made in the code and in the
documentation.
--- runtime_tools-1.8.4 -------------------------------------------------
OTP-8705 Miscellaneous updates.
--- sasl-2.1.9.1 --------------------------------------------------------
OTP-8502 A race condition in os:cmd/1 could cause the caller to
get stuck in os:cmd/1 forever.
OTP-8506 Use an infinity timeout in all calls to
gen_server:call() in the sasl application.
--- sasl-2.1.9.2 --------------------------------------------------------
OTP-8619 In R13B04 sys:get_status was modified to invoke format_status/2
in the callback module if the module exports that function.
This resulted in a change to the term returned from calling
sys:get_status on the supervisor module, since supervisor
is a gen_server and gen_server exports format_status. The
sasl release_handler_1 module had a dependency on the pre-R13B04
term returned by sys:get_status when invoked on a supervisor,
so the R13B04 change broke that dependency. This problem
has been fixed by change release_handler_1 to handle both
the pre-R13B04 and R13B04 terms that sys:get_status can
return from a supervisor.
--- snmp-4.16.1 ---------------------------------------------------------
OTP-8480 [agent] A minor mnesia related performance improvement.
OTP-8481 [manager] Fixed an upgrade/downgrade problem.
Upgrade/downgrade from/to 4.13.5 did not work for the net-if
process. This has now been fixed
--- snmp-4.16.2 ---------------------------------------------------------
OTP-8574 The SMI specifies that an table row OID should be named:
{ "1" }. An option has been introduced, relaxed_row_name_assign_check,
that allows for a more liberal numbering scheme.
OTP-8594 Changes to make snmp (forward) compatible with the new version
of the crypto application (released in R14). As of R14,
crypto is implemented using NIFs. Also, the API is more
strict.
OTP-8648 [manager] Changed default value for the MIB server cache.
Auto GC is now on by default.
OTP-8563 Decoding of Counter64 values larger then 9306882749598007295
fails. Counter64 is encoded as an 64 bit signed integer,
but is actually an unsigned integer, which the decoder does
not take into account.
OTP-8595 [compiler] Fails to compile non-contiguous BITS. Per Hedeland
OTP-8646 [manager] Raise condition causing the manager server process
to crash. Unregistering an agent while traffic (set/get-operations)
is ongoing could cause a crash in the manager server process
(raise condition).
--- snmp-4.17 -----------------------------------------------------------
OTP-8478 [agent] Added very basic support for multiple SNMPv3
EngineIDs in a single agent.
--- ssh-1.1.9 -----------------------------------------------------------
OTP-8550 The function ssh:connect/4 was not exported.
OTP-8644 Aligned error message with used version (SSH_FX_FAILURE
vs SSH_FX_NOT_A_DIRECTORY, the latter introduced in version
6).
OTP-8645 Resolved race condition when another connection is started
before a channel is opened in the first connection.
OTP-8535 The configuration parameter ip_v6_disabled is now available,
which makes it possible for the user to alter the IP version
SSH shall use.
OTP-8534 The ssh_connection:send operation now accepts infinity as
timeout.
OTP-8524 The connection handler now include stack traces when a channel
message is not handled correctly.
--- ssh-2.0 -------------------------------------------------------------
OTP-8524 The connection handler now include stack traces when a
channel message is not handled correctly.
OTP-8534 The ssh_connection:send operation now accepts infinity as
timeout.
OTP-8535 The configuration parameter ip_v6_disabled is now available,
which makes it possible for the user to alter the IP version
SSH shall use.
OTP-8550 The function ssh:connect/4 was not exported.
OTP-8596 Removed deprecated modules (ssh_ssh, ssh_sshd and ssh_cm) and
functions (ssh_sftp:connect and ssh_sftp:stop).
OTP-8644 Aligned error message with used version (SSH_FX_FAILURE vs
SSH_FX_NOT_A_DIRECTORY, the latter introduced in version 6).
OTP-8645 Resolved race condition when another connection is started
before a channel is opened in the first connection.
--- ssl-3.10.9 ----------------------------------------------------------
OTP-8510 Fixed a crash in the certificate certification part.
--- ssl-3.11 ------------------------------------------------------------
OTP-7046 Support for Diffie-Hellman. ssl-3.11 requires public_key-0.6.
OTP-8553 Moved extended key usage test for ssl values to ssl.
OTP-8557 Fixes handling of the option fail_if_no_peer_cert and some
undocumented options. Thanks to Rory Byrne.
OTP-7046 Support for Diffie-Hellman. ssl-3.11 requires public_key-0.6.
OTP-8517 New ssl now properly handles ssl renegotiation, and initiates
a renegotiation if ssl/ltls-sequence numbers comes close
to the max value. However RFC-5746 is not yet supported,
but will be in an upcoming release.
OTP-8545 When gen_tcp is configured with the {packet,http} option,
it automatically switches to expect HTTP Headers after a
HTTP Request/Response line has been received. This update
fixes ssl to behave in the same way. Thanks to Rory Byrne.
OTP-8554 Ssl now correctly verifies the extended_key_usage extension
and also allows the user to verify application specific
extensions by supplying an appropriate fun.
OTP-8560 Fixed ssl:transport_accept/2 to return properly when socket
is closed. Thanks to Rory Byrne.
--- ssl-4.0 -------------------------------------------------------------
OTP-8587 New ssl now support client/server-certificates signed by dsa
keys.
OTP-8695 Ssl has now switched default implementation and removed
deprecated certificate handling. All certificate handling is
done by the public_key application.
--- stdlib-1.17 ---------------------------------------------------------
OTP-8217 The module binary from EEP31 (and EEP9) is implemented.
OTP-8470 The Erlang code preprocessor (epp) sent extra messages on the
form {eof,Location} to the client when parsing the file
attribute. This bug, introduced in R11B, has been fixed.
OTP-8473 The abstract type 'fun' could not be printed by the Erlang
pretty printer (erl_pp). This bug has been fixed.
OTP-8501 The erlang pretty printer (erl_pp) no longer quotes atoms in
types.
OTP-8503 The Erlang code preprocessor (epp) now considers records with
no fields as typed.
OTP-8521 Added function zip:foldl/3 to iterate over zip archives.
Added functions to create and extract escripts. See
escript:create/2 and escript:extract/2.
The undocumented function escript:foldl/3 has been removed.
The same functionality can be achieved with the more flexible
functions escript:extract/2 and zip:foldl/3.
Record fields has been annotated with type info. Source files
as been adapted to fit within 80 chars and trailing
whitespace has been removed.
OTP-8522 The Erlang parser no longer duplicates the singleton type
undefined in the type of record fields without initial value.
OTP-8539 A regular expression with many levels of parenthesis could
cause a buffer overflow. That has been corrected. (Thanks to
Michael Santos.)
OTP-8562 When defining macros the closing right parenthesis before the
dot is now mandatory.
OTP-8567 The function erl_scan:reserved_word/1 no longer returns true
when given the word spec. This bug was introduced in
STDLIB-1.15.3 (R12B-3).
OTP-8577 Some properties of a compiled re pattern are defined to allow
for guard tests.
OTP-8579 Local and imported functions now override the auto-imported
BIFs when the names clash. The pre R14 behaviour was that
auto-imported BIFs would override local functions. To avoid
that old programs change behaviour, the following will
generate an error:
Doing a call without explicit module name to a local function
having a name clashing with the name of an auto-imported BIF
that was present (and auto-imported) before OTP R14A
Explicitly importing a function having a name clashing with
the name of an autoimported BIF that was present (and
autoimported) before OTP R14A
Using any form of the old compiler directive nowarn_bif_clash
If the BIF was added or auto-imported in OTP R14A or later,
overriding it with an import or a local function will only
result in a warning,
To resolve clashes, you can either use the explicit module
name erlang to call the BIF, or you can remove the
auto-import of that specific BIF by using the new compiler
directive -compile({no_auto_import,[F/A]})., which makes all
calls to the local or imported function without explicit
module name pass without warnings or errors.
The change makes it possible to add auto-imported BIFs
without breaking or silently changing old code in the future.
However some current code ingeniously utilizing the old
behaviour or the nowarn_bif_clash compiler directive, might
need changing to be accepted by the compiler.
OTP-8584 The undocumented, unsupport, and deprecated function
lists:flat_length/1 has been removed.
OTP-8589 A bug in re that could cause certain regular expression
matches never to terminate is corrected. (Thanks to Michael
Santos and Gordon Guthrie.)
OTP-8597 Nested records can now be accessed without parenthesis. See
the Reference Manual for examples. (Thanks to YAMASHINA Hio
and Tuncer Ayaz.)
OTP-8623 receive statements that can only read out a newly created
reference are now specially optimized so that it will execute
in constant time regardless of the number of messages in the
receive queue for the process. That optimization will benefit
calls to gen_server:call(). (See gen:do_call/4 for an example
of a receive statement that will be optimized.)
OTP-8625 The beam_lib:cmp/2 function now compares BEAM files in
stricter way. The BEAM files will be considered different if
there are any changes except in the compilation information
("CInf") chunk. beam_lib:cmp/2 used to ignore differences in
the debug information (significant for Dialyzer) and other
chunks that did not directly change the run-time behavior.
OTP-8628 The documentation of lists:keysort/2 states that the sort is
stable.
OTP-8630 When a gen_server, gen_fsm process, or gen_event terminates
abnormally, sometimes the text representation of the process
state can occupy many lines of the error log, depending on
the definition of the state term. A mechanism to trim out
parts of the state from the log has been added (using a
format_status/2 callback). See the documentation.
OTP-8635 The shell's line editing has been improved to more resemble
the behaviour of readline and other shells. (Thanks to Dave
Peticolas)
OTP-8656 Calling sys:get_status() for processes that have globally
registered names that were not atoms would cause a crash.
Corrected. (Thanks to Steve Vinoski.)
OTP-8657 The Erlang scanner has been augmented with two new tokens: ..
and ....
OTP-8664 Expressions evaluating to integers can now be used in types
and function specifications where hitherto only integers were
allowed ("Erlang_Integer").
OTP-8665 The Erlang code preprocessor (epp) did not correctly handle
premature end-of-input when defining macros. This bug,
introduced in STDLIB 1.16, has been fixed.
OTP-8668 The compiler optimizes record operations better.
OTP-8669 The recently added BIFs erlang:min/2, erlang:max/2 and
erlang:port_command/3 are now auto-imported (as they were
originally intended to be). Due to the recent compiler change
(OTP-8579), the only impact on old code defining it's own
min/2, max/2 or port_command/3 functions will be a warning,
the local functions will still be used. The warning can be
removed by using
-compile({no_auto_import,[min/2,max/2,port_command/3]}). in
the source file.
OTP-8671 Now, binary_to_term/2 is auto-imported. This will cause a
compile warning if and only if a module has got a local
function with that name.
OTP-8687 The predefined builtin type tid() has been removed. Instead,
ets:tid() should be used.
--- syntax_tools-1.6.6 --------------------------------------------------
OTP-8709 Minor changes and clean-ups.
--- test_server-3.4 -----------------------------------------------------
OTP-8492 Returning {fail,Reason} from the framework end_tc function
was not handled properly by Test Server for all test suite
functions.
OTP-8495 It is now possible for the Test Server framework end_tc
function to change the status of the test case from ok or
auto-skipped to failed by returning {fail,Reason}.
OTP-8500 Test Server will now call the end_per_testcase/2 function
even if the test case has been terminated explicitly (with
abort_current_testcase/1), or after a timetrap timeout. Under
these circumstances the return value of end_per_testcase is
completely ignored. Therefore the function will not be able
to change the reason for test case termination by returning
{fail,Reason}, nor will it be able to save data with
{save_config,Data}.
OTP-8682 If the framework end_tc function would hang and get aborted
by Test Server, there was no indication of failure in the
logs. This has been fixed.
OTP-8689 Previously, a repeat property of a test case group specified
the number of times the group should be repeated after the
main test run. I.e. {repeat,N} would case the group to
execute 1+N times. To be consistent with the behaviour of the
run_test repeat option, this has been changed. N now
specifies the absolute number of executions instead.
--- tools-2.6.6 ---------------------------------------------------------
OTP-8469 A race condition affecting Cover has been removed.
OTP-8472 Xref has been updated to use the re module instead of the
deprecated regexp module.
OTP-8530 Emacs improvements:
Fixed emacs-mode installation problems.
Fixed a couple of -spec and -type indentation and font-lock
problems.
Fixed error messages on emacs-21.
Magnus Henoch fixed several issues.
Ralf Doering, Klas Johansson and Chris Bernard contributed
various emacs-eunit improvements.
Klas Johansson and Dave Peticolas added emacs-flymake
support.
OTP-8647 When given the option {builtins,true} Xref now adds calls to
operators.
OTP-8706 eprof has been reimplemented with support in the Erlang
virtual machine and is now both faster (i.e. slows down the
code being measured less) and scales much better. In
measurements we saw speed-ups compared to the old eprof
ranging from 6 times (for sequential code that only uses one
scheduler/core) up to 84 times (for parallel code that uses 8
cores).
Note: The API for the eprof has been cleaned up and extended.
See the documentation.
--- tv-2.1.4.5 ----------------------------------------------------------
OTP-8674 Warnings due to new autoimported BIFs removed
--- webtool-0.8.7 -------------------------------------------------------
OTP-8651 Up until now Netscape has been the default web browser on
Unix/Linux. Webtool has now been updated to start Firefox as
default browser instead.
--- wx-0.98.6 -----------------------------------------------------------
OTP-8656 Calling sys:get_status() for processes that have globally
registered names that were not atoms would cause a crash.
Corrected. (Thanks to Steve Vinoski.)
--- xmerl-1.2.5 ---------------------------------------------------------
OTP-8537 All Erlang files are now built by the test server instead of
the test directory Makefile.
Erlang files in data directories are now built by the test
suites instead of using prebuilt versions under version
control.
Removed a number of obsolete guards.
OTP-8599 An empty element declared as simpleContent was not properly
validated.
