The super carrier feature can be used in different ways. It can for example be used for pre-allocation of all memory that the runtime system should be able to use. By default the super carrier is disabled. It is enabled by passing the +MMscs command line argument. For more information see the documentation of the +MMsco, +MMscrfsd, +MMscrpm, +MMscs, +MMusac, and, +Mlpm command line arguments in the erts_alloc(3) documentation. Since it is disabled by default there should be no impact on system characteristics if not used. This change has been marked as a potential incompatibility since the returned list when calling erlang:system_info({allocator, mseg_alloc}) now also include an {erts_mmap, _} tuple as one element in the list. --- otp ----------------------------------------------------------------- OTP-11323 Remove ^L characters hidden randomly in the code. Not those used in text files as delimiters. Thanks to Pierre Fenoll. OTP-11448 Update INSTALL md, added info how to generate configure file if building from git. Thanks to Jakub Oboza. OTP-11472 Fixed typo in gen_fsm example. Thanks to Boris M�hmer. --- asn1-2.0.4 ---------------------------------------------------------- OTP-11314 The new option 'no_ok_wrapper' generates M:encode/2 and M:decode/2 functions that don't wrap the return value in an {ok,...} tuple. OTP-11319 The default value for a BIT STRING would not always be recognized, causing the encoding to be incorrect for the DER/PER/UPER encodings. OTP-11360 The asn1 application would fail to build if the .erlang file printed something to standard output. OTP-11411 An union of integer ranges in an INTEGER constraint could sometimes be interpreted as the intersection of the range. OTP-11415 Extensible, multiple single value constraints (such as INTEGER (1|17, ...)) would be incorrectly encoded. OTP-11504 The ASN.1 compiler would fail to compile a constraint with values given for for the extension part (such as INTEGER (1..10, ..., 11..20)). --- common_test-1.7.4 --------------------------------------------------- OTP-10631 Return values from group and testcase info functions are now properly checked, and associated test cases are auto skipped if a return value is invalid. OTP-11305 The way Common Test handles skipping of test cases has been updated. In previous versions, returning {skip,Reason} from a configuration function (such as init_per_suite or init_per_group), resulted in all affected test cases getting skipped with status auto_skipped. This was inappropriate, since this status is supposed to be used to inform that Common Test has taken the initiative to skip something (e.g. a test case group if init_per_group failed). Therefore, in this version of Common Test, whenever the user skips a suite, group, or individual test case (by means of a configuration function or test specification term), the affected test cases get the status user_skipped instead. This update has meant a few changes that may affect Common Test users in various ways: -- The test results and statistics will be affected, which is important to know when running regression tests and comparing results to previous test runs. -- Users that read or parse the textual log file suite.log will notice that an auto skipped function is now reported as auto_skipped rather than skipped as before. -- When require fails in an info function (such as suite/0 or group/1), all affected configuration functions and test cases are marked as auto_skipped. -- If Common Test detects an error in the test suite (such as e.g. an invalid all/0 function), all affected configuration functions and test cases are marked as auto_skipped. -- If a repeated test run session reaches a deadline with force_stop enabled, all remaining test cases are marked as auto_skipped rather than user_skipped as before. -- The event messages that Common Test generates during test runs have been affected by this update. For details see OTP-11524. OTP-11401 Fix cth_log_redirect.erl to fulfill gen_event behaviour. Thanks to Roberto Aloi. OTP-11409 Returning {skip, Reason} from a pre_end_per_group/3 user hook function would result in an exit in the Common Test cth_log_redirect hook. This problem has been solved. OTP-11478 When the netconf server did not respond to the close-session request, the call to ct_netconfc:close_session/2 would hang forever waiting for the netconf client to terminate. This has been corrected. The client will now always terminate (and take down the connection) if the close-session request times out. OTP-11523 The first argument of the CT hook callback function on_tc_skip/3 has been modified. When this function is called for init_per_group or end_per_group, the value of the first argument is now {init_per_group,GroupName} or {end_per_group,GroupName}. OTP-11524 The following modifications have been made to the event messages that Common Test sends during test execution: -- For the tc_auto_skip event, the value of the Func element has changed from end_per_group to {end_per_group,GroupName}. -- When require fails in an info function, such as suite/0 or group/1, the init configuration function is now reported as auto_skipped intead of skipped, with the tc_done event. -- When require fails in an info function because of a configuration name already in use, the tc_done event now reports the error with a tuple (of size 2) tagged failed instead of skipped. Please see the Event Handling chapter in the Common Test User's Guide for reference. --- compiler-4.9.4 ------------------------------------------------------ OTP-11267 Lift 'after' blocks to zeroary functions. Thanks to Anthony Ramine. OTP-11455 Typo fix ambigous -> ambiguous. Thanks to Leo Correa. --- crypto-3.2 ---------------------------------------------------------- OTP-11510 Fix uninitialized pointers in crypto (Thanks to Anthony Ramine) --- dialyzer-2.6.2 ------------------------------------------------------ OTP-11374 Fixed a dialyzer crash when using remote types in the tail position of a maybe_improper_list/2 type. Thanks to Kostis Sagonas --- diameter-1.4.4 ------------------------------------------------------ OTP-11367 Fix setting of End-to-End and Hop-by-Hop Identifiers in outgoing DWA. Broken by OTP-11184, which caused the identifiers to be set anew, discarding the values from the incoming DWR. OTP-11395 Fix handling of 5014, DIAMETER_INVALID_AVP_LENGTH. The error was detected as 5004, DIAMETER_INVALID_AVP_VALUE, for some Diameter types, in which case an AVP length that pointed past the end of a message resulted in encode failure. --- diameter-1.5 -------------------------------------------------------- OTP-11168 Rename reconnect_timer to connect_timer. The former is still accepted for backwards compatibility, but the name is misleading given the semantics of the timer. OTP-11348 Extend diameter_make(3). Dictionaries can now be compiled from strings, not just filesystem paths, and results can be returned instead of written to the filesystem. OTP-11361 Remove hardcoding of diameter_base as @prefix on dictionaries for application id 0. OTP-11514 Fix silent make rules (Thanks to Anthony Ramine) --- eldap-1.0.2 --------------------------------------------------------- OTP-11336 The ldap client eldap now supports the start_tls operation. This upgrades an existing tcp connection to encryption using tls, if the server supports it. See eldap:start_tls/2 and /3. OTP-11354 Removed {verify,0} from ssl-options because eldap does not support peer verification. Thanks to Florian Waas for reporting. --- erl_interface-3.7.15 ------------------------------------------------ OTP-11517 Silence warnings (Thanks to Anthony Ramine) --- erts-5.10.3.1 ------------------------------------------------------- OTP-11318 Memory allocators will be able to create sys_alloc carriers as fallback, if mseg_alloc cannot create more carriers, on systems with posix_memalign() support. This is similar to how it worked in pre-R16 releases. Windows systems will create carriers using _aligned_malloc() and can by this use the new optimized allocator header scheme introduced in R16 on other platforms. --- erts-5.10.4 --------------------------------------------------------- OTP-10229 New socket functions inet:socknames/1,2 and inet:peernames/1,2 have been implemented. They are useful for SCTP sockets since they return all addresses for an association. For other sockets they fall back to inet:sockname/1 and inet:peername/1, so the new functions can replace the old for any application that wants to be multi address aware yet socket type agnostic. See the documentation. OTP-11149 A new memory allocation feature called "super carrier" has been introduced. The super carrier feature can be used in different ways. It can for example be used for pre-allocation of all memory that the runtime system should be able to use. By default the super carrier is disabled. It is enabled by passing the +MMscs command line argument. For more information see the documentation of the +MMsco, +MMscrfsd, +MMscrpm, +MMscs, +MMusac, and, +Mlpm command line arguments in the erts_alloc(3) documentation. Since it is disabled by default there should be no impact on system characteristics if not used. This change has been marked as a potential incompatibility since the returned list when calling erlang:system_info({allocator, mseg_alloc}) now also include an {erts_mmap, _} tuple as one element in the list. OTP-11170 When normalizing paths, erl_prim_loader would always convert backslash to forward slash. This is correct on Windows, but not on other operating systems. erl_prim_loader now checks which OS is running before performing this conversion. OTP-11349 Fixed syslog defines and defined LOG_ERR for systems without syslog.h. Thanks to Matt Lewandowsky. OTP-11350 Check all pattern arguments passed to binary:matches/2. Thanks to Mike Sassak. OTP-11351 Fix two small silent rules omissions. Thanks to Anthony Ramine. OTP-11362 Added erlang:system_info(ets_limit) to provide a way to retrieve the runtime's maximum number of ETS tables. Thanks to Steve Vinoski OTP-11371 Teach configure to detect if posix_memalign cannot align to more than the system page size. For cross-compiled systems a new environment variable called erl_xcomp_posix_memalign has been introduced to indicate whether posix_memalign should be used. OTP-11381 Fix bsr bug occurring when shifting a huge number a huge number of bits to the right. Thanks to Lars Hesel Christensen. OTP-11410 Fix memory leak for distributed monitors OTP-11414 Fix various typos in erts, kernel and ssh. Thanks to Martin Hässler. OTP-11420 Crashdumps initiated by out-of-memory on process spawn could cause the beam to segfault during crashdump writing due to invalid pointers. The pointers are invalid since the process creation never finished. This fix removes these processes from the printouts. Reported by Richard Carlsson. OTP-11446 Add new BIF os:unsetenv/1 which deletes an environment variable. Thanks to Martin Hässler. OTP-11450 Crash dumps from 64-bit Erlang machines would have all memory addresses truncated to 32 bits, which could cause trouble inspecting processes message queues and stacks in the crashdump viewer. OTP-11456 Threads other than schedulers threads could make thread unsafe accesses when support for migration of memory carriers had been enabled, i.e., when the +Macul command line flag had been passed to erl. This could cause corruption of the VMs internal state. This bug was introduced in erts-5.10.2 when the support for migration of memory carriers was introduced. OTP-11479 Fix bug in binary_to_term for invalid bitstrings and very large binaries (>2Gb). OTP-11489 Introduced a new guarantee regarding exit signals from ports: If the process calling one of the synchronous port BIFs listed below is linked to the port identified by the first argument, and the port exits before sending the result of the port operation, the exit signal issued due to this link will be received by the processes before the BIF returns, or fail with an exception due to the port not being open. The synchronous port BIFs are: -- port_close/1 -- port_command/2 -- port_command/3 -- port_connect/2 -- port_control/3 -- erlang:port_call/3 -- erlang:port_info/1 -- erlang:port_info/2 Note that some ports under certain circumstances unlink themselves from the calling process before exiting, i.e. even though the process linked itself to the port there might be no link triggering an exit signal. Characteristics impact: The return or exception from the synchronous port BIF will be delayed if the port simultaneously exit due to some issue unrelated to the outstanding synchronous port BIF call. In all other cases characteristics are unchanged. OTP-11491 Under rare circumstances a process calling inet:close/1, gen_tcp:close/1, gen_udp:close/1, or gen_sctp:close/1 could hang in the call indefinitely. OTP-11496 Fix bug that could cause a 32-bit emulator to always crash at start (since R16B01) depending on the alignment of static data in the beam executable. OTP-11501 Fix benign bugs regarding bitstring compare. Only a nuisance for debug and valgrind VM. OTP-11517 Silence warnings (Thanks to Anthony Ramine) OTP-11521 The default wordsize of the emulator (beam) is now determined by compiler default on Mac OSX (Darwin). This was previously forced to 32bits by the configure script unless otherwise specified. --- eunit-2.2.6 --------------------------------------------------------- OTP-11373 Fix I/O-protocol error handling in eunit. Thanks to Yuki Ito. OTP-11467 Do not attempt to detect lists of printable characters in format. Thanks to Roberto Aloi. OTP-11516 Fix silent make rule (Thanks to Anthony Ramine ) --- hipe-3.10.2.2 ------------------------------------------------------- OTP-11374 Fixed a dialyzer crash when using remote types in the tail position of a maybe_improper_list/2 type. Thanks to Kostis Sagonas --- ic-4.3.4 ------------------------------------------------------------ OTP-11351 Fix two small silent rules omissions. Thanks to Anthony Ramine. OTP-11517 Silence warnings (Thanks to Anthony Ramine) --- inets-5.9.7 --------------------------------------------------------- OTP-11037 The ftp client now supports ftp over tls (ftps). OTP-11276 Fix httpd config option 'script_timeout' and fixed httpd config option 'keep_alive_timeout'. Thanks to Johannes Weissl. OTP-11312 Make httpc:request_cancel/[1,2] asynchronous. Previously these functions tried to guarantee request answer would not reach the client, which only worked for some of the use cases. Now these functions are totally asynchronous which makes it the clients responsibility to disregard possible answers to canceled requests. Also pipelining implementation has been changed to improve the utilization factor. Further investigation of possible enhancements in this area are planned for later. OTP-11328 [httpd] Add handling of new response for mod_head (otherwise causing case_clause crash). Also updated logging: Removed logging for keep-alive connections timeout (this is a normal occurrence and not an error) and some access-log body size corrections. --- kernel-2.16.4 ------------------------------------------------------- OTP-10229 New socket functions inet:socknames/1,2 and inet:peernames/1,2 have been implemented. They are useful for SCTP sockets since they return all addresses for an association. For other sockets they fall back to inet:sockname/1 and inet:peername/1, so the new functions can replace the old for any application that wants to be multi address aware yet socket type agnostic. See the documentation. OTP-11377 Fix the typespec for the inet:ifget/2 and inet:ifget/3 return value. Thanks to Ali Sabil. OTP-11379 Add more SCTP errors as described in RFC 4960. Thanks to Artem Teslenko. OTP-11414 Fix various typos in erts, kernel and ssh. Thanks to Martin Hässler. OTP-11446 Add new BIF os:unsetenv/1 which deletes an environment variable. Thanks to Martin Hässler. OTP-11471 Fix rpc multicall sample code. Thanks to Edwin Fine. OTP-11491 Under rare circumstances a process calling inet:close/1, gen_tcp:close/1, gen_udp:close/1, or gen_sctp:close/1 could hang in the call indefinitely. --- mnesia-4.11 --------------------------------------------------------- OTP-11375 Fixed a race in mnesia which could cause hanging transaction when sticky locks had been used. Thanks janchochol. OTP-11485 Fixed dirty_update_counter which could return ok, thanks Anton Ryabkov. --- observer-1.3.1.2 ---------------------------------------------------- OTP-11335 The documentation for ttb:tracer/2 incorrectly stated that there was an option named 'overload', while the correct name used in the implementation is 'overload_check'. OTP-11475 Fixed typo in observer documentation. Thanks to Dave Parfitt. --- odbc-2.10.18 -------------------------------------------------------- OTP-11483 Configure now also checks for the existence of the sql.h header file --- os_mon-2.2.14 ------------------------------------------------------- OTP-11454 Fix incorrect reporting of memory on OS X via memsup. Thanks to Christopher Meiklejohn. --- public_key-0.21 ----------------------------------------------------- OTP-11380 Fixed a little typo in public_key documentation. Thanks to Tomas Morstein. OTP-11470 public_key: Workaround for incorrectly encoded utf8 emailAddress. Thanks to Andrew Bennett. --- runtime_tools-1.8.13 ------------------------------------------------ OTP-11520 Observer did not produce correct result when ERTS internal memory allocators had been disabled. --- sasl-2.3.4 ---------------------------------------------------------- OTP-8479 Added a boot file which skips loading the "$HOME/.erlang" file on startup. Enable by starting erlang with "erl -boot no_dot_erlang". OTP-11464 Don't try to add the log_mf_h handler in sasl unless configured to do so. Thanks to Richard Carlsson. OTP-11507 Fix confusing documentation about error handlers in SASL.(Thanks to Richard Carlsson) OTP-11529 A bug in the mechanism for upgrading core parts of Erlang/OTP (emulator, kernel, stdlib, sasl) caused a switch of paths between stdlib and sasl in the intermediate .script/.boot file. The bug was introduces along with this upgrade mechanism in R15B. It has now been corrected. (Thanks to Tobias Schlager) --- snmp-4.25 ----------------------------------------------------------- OTP-11307 [manager] Improved handling of unexpected/invalid return values and crashes from called snmpm_user callback functions. OTP-11352 Enable SNMP to create missing database directories. Add {db_init_error, create_db_and_dir} option to SNMP manager and agent. This allows them to create any missing parent directories for db_dir, rather than treating any missing directories as a fatal error. The default for db_init_error, which is terminate, is unchanged. OTP-11412 [manager] Wrong block cypher type used for AES ('aes_cbf128' instead of 'aes_cfb128') when performing AES block encrypt/decrypt. OTP-11413 [manager] When performing the AES encryption, invalid values for the EngineBoots and EngineTime was used. The values of the local agent was used, which would have produced some values if an agent was actually running. If not it would have caused a crash. --- ssh-3.0 ------------------------------------------------------------- OTP-10976 Add option to disallow CLI OTP-11296 Add sockname and user to ssh:connection_info/2 OTP-11339 The ssh cli is now faster at close and before new prompt. OTP-11363 Ssh process structure was redesigned to better map to what is truly parallel this has solved a lot of strange timing issues that sometimes would occur, for instance a process leak could happen when a lot of connections where taken up and down in parallel in a short period of time. Also backwards compatible clauses to "original" but never supported features has been removed. Impact: Increases flow efficiency OTP-11414 Fix various typos in erts, kernel and ssh. Thanks to Martin Hässler. OTP-11449 Correct private_key type documentation in ssh_server_key_api. Thanks to Tristan Sloughter. OTP-11490 The functions in ssh_no_io.erl did not mimic the functions in ssh_io.erl correctly, the arity was incorrect for some functions which caused ssh to fail in the wrong way. --- ssl-5.3.2 ----------------------------------------------------------- OTP-11370 Honors the clients advertised support of elliptic curves and no longer sends incorrect elliptic curve extension in server hello. OTP-11376 Fix initialization of DTLS fragment reassembler, in previously contributed code, for future support of DTLS . Thanks to Andreas Schultz. OTP-11447 Remove extraneous dev debug code left in the close function. Thanks to Ken Key. OTP-11457 Corrected type error in client_preferred_next_protocols documentation. Thanks to Julien Barbot. OTP-11460 Add SSL Server Name Indication (SNI) client support. Thanks to Julien Barbot. --- stdlib-1.19.4 ------------------------------------------------------- OTP-11398 Fix typo in gen_server.erl. Thanks to Brian L. Troutwine. OTP-11442 Add XML marker for regexp syntax. Thanks to Håkan Mattson. OTP-11465 Spec for atan2 should be atan2(Y, X), not atan2(X, Y). Thanks to Ary Borenszweig. --- syntax_tools-1.6.12 ------------------------------------------------- OTP-11506 Fix transformation of implicit funs in igor (Thanks to Anthony Ramine) --- test_server-3.6.4 --------------------------------------------------- OTP-11305 The way Common Test handles skipping of test cases has been updated. In previous versions, returning {skip,Reason} from a configuration function (such as init_per_suite or init_per_group), resulted in all affected test cases getting skipped with status auto_skipped. This was inappropriate, since this status is supposed to be used to inform that Common Test has taken the initiative to skip something (e.g. a test case group if init_per_group failed). Therefore, in this version of Common Test, whenever the user skips a suite, group, or individual test case (by means of a configuration function or test specification term), the affected test cases get the status user_skipped instead. This update has meant a few changes that may affect Common Test users in various ways: -- The test results and statistics will be affected, which is important to know when running regression tests and comparing results to previous test runs. -- Users that read or parse the textual log file suite.log will notice that an auto skipped function is now reported as auto_skipped rather than skipped as before. -- When require fails in an info function (such as suite/0 or group/1), all affected configuration functions and test cases are marked as auto_skipped. -- If Common Test detects an error in the test suite (such as e.g. an invalid all/0 function), all affected configuration functions and test cases are marked as auto_skipped. -- If a repeated test run session reaches a deadline with force_stop enabled, all remaining test cases are marked as auto_skipped rather than user_skipped as before. -- The event messages that Common Test generates during test runs have been affected by this update. For details see OTP-11524. --- tools-2.6.13 -------------------------------------------------------- OTP-11394 Add iodata, nonempty_string to built-in type highlighting for emacs. Thanks to Paul Oliver. OTP-11417 Erlang-specific compilation error regexp is added in erlang-eunit.el. This defvar was earlier in erlang.el, but was erroneously removed in R15B02, while still used by erlang-eunit.el. OTP-11439 Take compiler options from beam in cover:compile_beam. Thanks to Péter Gömöri. OTP-11517 Silence warnings (Thanks to Anthony Ramine) --- wx-1.1.1 ------------------------------------------------------------ OTP-11393 wx initialization hanged with wxWidgets-3.0 on mac. Fixed a crash with wxListBox on wxWidgets-3.0 (thanks Sergei Golovan) Fixed documentation links. Fixed event callbacks cleanup. OTP-11505 Improve documentation (Thanks to Boris Mühmer) OTP-11515 Fix silent make rules (Thanks to Anthony Ramine) --- xmerl-1.3.5 --------------------------------------------------------- OTP-11461 Teach xmerl_xpath to resolve context namespaces in more cases. Thanks to Daniel White. OTP-11463 Avoid serialization on code_server in xmerl:export(). Thanks to Richard Carlsson.
