This will sometimes differ from previous returned reasons, however those where only documented as term() and should for that reason not be relied on. OTP-15662 Application(s): kernel Handler specific configuration parameters for the standard handler logger_std_h are changed to be more intuitive and more similar to the disk_log handler. Earlier there was only one parameter, type, which could have the values standard_io, standard_error, {file,FileName} or {file,FileName,Modes}. This is now changed, so the following parameters are allowed: type = standard_io | standard_error | file file = file:filename() modes = [file:mode()] All parameters are optional. type defaults to standard_io, unless a file name is given, in which case it defaults to file. If type is set to file, the file name defaults to the same as the handler id. The potential incompatibility is that logger:get_config/0 and logger:get_handler_config/1 now returns the new parameters, even if the configuration was set with the old variant, e.g. #{type=>{file,FileName}}. --------------------------------------------------------------------- --- OTP-21.3 -------------------------------------------------------- --------------------------------------------------------------------- --- Fixed Bugs and Malfunctions --- OTP-15657 Application(s): erts, otp, tools Minor fixes for make clean. --- Improvements and New Features --- OTP-15460 Application(s): erl_docgen, otp *** HIGHLIGHT *** The HTML reference documentation shows the OTP version where modules and functions were first introduced.

This is now corrected. OTP-15584 Application(s): common_test Related Id(s): ERIERL-282 The status of a test case which failed with timetrap timeout in end_per_testcase could not be modified by returning {fail,Reason} from a post_end_per_testcase hook function. This is now corrected. --- Improvements and New Features --- OTP-15229 Application(s): common_test Related Id(s): ERIERL-203 A new variant of the newline option to ct_telnet:cmd/3 and ct_telnet:send/3 is added, which allows to specify a string to append as newline indicator on a command. By default, the value is "\n", but in some cases it is required to be "\r\n", which this option allows. A faulty regular expression given as parameter to ct_telnet:expect/2,3 would earlier crash and look like an internal error in common_test. A better error indication is now given, but the test case will still fail. OTP-15298 Application(s): common_test Since the yang RFC allows more than one top element of config data in an edit-config element, ct_netconfc:edit_config/3,4,5 can now take a list of XML elements.

OTP-15490 Application(s): erts, kernel Fix bug where doing seq_trace:reset_trace() while another process was doing a garbage collection could cause the run-time system to segfault. OTP-15494 Application(s): erts Fix reading of ancillary data from packet oriented sockets on old Linux kernel versions. Without this fix, getting the data would cause the port to enter an infinite loop. OTP-15527 Application(s): erts Fix bug where crash dumping or doing erlang:system_info(procs) while another process was doing a garbage collection could cause the run-time system to segfault. OTP-15556 Application(s): erts Fix erlang:system_info(kernel_poll) to return correct value. Before this fix, the call always returned false. OTP-15567 Application(s): erts Fix bug in enif_make_map_from_arrays that would produce broken maps when number of keys were 32. Bug exists since OTP 21.0. OTP-15583 Application(s): erts Related Id(s): PR-2118 Fix a bug in binary:encode_unsigned that may cause a read of uninitialized memory. The bug existed since the function was added (OTP R16B02). OTP-15599 Application(s): erts Related Id(s): ERIERL-298 Fixed a bug that could cause heart to kill an exiting node before it had time to flush all buffered writes. If environment variable HEART_KILL_SIGNAL=SIGABRT was set a superfluous core dump could also be generated. OTP-15604 Application(s): erts Fix enif_consume_timeslice to be a no-op on dirty scheduler and not crash debug compiled emulator. OTP-15629 Application(s): erts Fixed macro redefinition warnings. OTP-15650 Application(s): erts Related Id(s): ERL-854, PR-2161 to_erl fixed to not garble terminal input beyond 7-bit ASCII. OTP-15657 Application(s): erts, otp, tools Minor fixes for make clean. OTP-15660 Application(s): erts Related Id(s): ERL-869 Fixed a bug in all ets:select* and ets:match* functions that could in some rare cases lead to very poor performance. --- Improvements and New Features --- OTP-15375 Application(s): erts Add erlang:system_flag(system_logger, Pid) and erlang:system_info(system_logger). This system_flag can be used to set the process that will receive the logging messages generated by ERTS. OTP-15503 Application(s): erts Related Id(s): PR-2052 integer_to_list/2 and integer_to_binary/2 are now implemented in C, improving their performance. OTP-15514 Application(s): erts Related Id(s): ERL-774 Improved term_to_binary to do more fair reduction count and yielding when encoding large byte lists (strings). OTP-15555 Application(s): erts Related Id(s): ERIERL-231 Made internal port drivers more robust against erlang:port_control with invalid arguments and added documentation warnings about such abuse. OTP-15558 Application(s): erts Related Id(s): ERL-725 Fix bug on NetBSD where the exit_status from a port program would never be sent. OTP-15576 Application(s): erts Related Id(s): ERL-843 There is a new function persistent:term(Key, Default) to allow specifying a default when looking up a persistent term. OTP-15580 Application(s): erts Related Id(s): PR-2113 A transitory emulator option '+ztma true' has been added to allow running existing BEAM code that relies on "tuple calls" (dispatch on parameterized modules) which has been compiled under OTP 20 or earlier. This option will be removed in OTP 22, so such modules should eventually be recompiled with the +tuple_calls option. Full runtime dependencies of erts-10.3: kernel-6.1, sasl-3.3, stdlib-3.5 --------------------------------------------------------------------- --- ftp-1.0.2 ------------------------------------------------------- --------------------------------------------------------------------- The ftp-1.0.2 application can be applied independently of other applications on a full OTP 21 installation. --- Fixed Bugs and Malfunctions --- OTP-15659 Application(s): ftp Related Id(s): ERIERL-316 Fixed timing related bug that could make ftp functions behave badly.

When httpd was started with explicit erl_script_timeout, the value of the option was converted to milliseconds before storage. Subsequent calls to httpd:info/1 returned the input value multiplied by 1000. This change fixes the handing of erl_script_timeout by storing the timeout in seconds and converting to milliseconds before usage. --- Improvements and New Features --- OTP-15508 Application(s): inets Related Id(s): ERL-816 Enhance documentation Full runtime dependencies of inets-7.0.6: erts-6.0, kernel-3.0, mnesia-4.12, runtime_tools-1.8.14, ssl-5.3.4, stdlib-3.5 --------------------------------------------------------------------- --- kernel-6.3 ------------------------------------------------------ --------------------------------------------------------------------- Note! The kernel-6.3 application can *not* be applied independently of other applications on an arbitrary OTP 21 installation. On a full OTP 21 installation, also the following runtime dependency has to be satisfied: -- erts-10.2.5 (first satisfied in OTP 21.2.7) --- Fixed Bugs and Malfunctions --- OTP-14702 Application(s): kernel Related Id(s): PR-2066 If for example the /etc/hosts did not come into existence until after the kernel application had started, its content was never read. This bug has now been corrected. OTP-15490 Application(s): erts, kernel Fix bug where doing seq_trace:reset_trace() while another process was doing a garbage collection could cause the run-time system to segfault. OTP-15557 Application(s): kernel Related Id(s): PR-2117 Fix erl_epmd:port_please spec to include atom() and string(). OTP-15578 Application(s): kernel Related Id(s): ERL-850 The Logger handler logger_std_h now keeps track of the inode of its log file in order to re-open the file if the inode changes. This may happen, for instance, if the log file is opened and saved by an editor. OTP-15602 Application(s): kernel When user specific file modes are given to the logger handler logger_std_h, they were earlier accepted without any control. This is now changes, so Logger will adjust the file modes as follows: - If raw is not found in the list, it is added. - If none of write, append or exclusive are found in the list, append is added. - If none of delayed_write or {delayed_write,Size,Delay} are found in the list, delayed_write is added. --- Improvements and New Features --- OTP-15479 Application(s): kernel The standard logger handler, logger_std_h, now has a new internal feature for log rotation. The rotation scheme is as follows: The log file to which the handler currently writes always has the same name, i.e. the name which is configured for the handler. The archived files have the same name, but with extension ".N", where N is an integer. The newest archive has extension ".0", and the oldest archive has the highest number. The size at which the log file is rotated, and the number of archive files that are kept, is specified with the handler specific configuration parameters max_no_bytes and max_no_files respectively. Archives can be compressed, in which case they get a ".gz" file extension after the integer. Compression is specified with the handler specific configuration parameter compress_on_rotate. OTP-15600 Application(s): kernel The new functions logger:i/0 and logger:i/1 are added. These provide the same information as logger:get_config/0 and other logger:get_*_config functions, but the information is more logically sorted and more readable. OTP-15601 Application(s): kernel Logger is now protected against overload due to massive amounts of log events from the emulator or from remote nodes. OTP-15625 Application(s): kernel Logger now uses os:system_time/1 instead of erlang:system_time/1 to generate log event timestamps. OTP-15642 Application(s): kernel Related Id(s): PR-2164 Add functions application:set_env/1,2 and application:set_env/2. These take a list of application configuration parameters, and the behaviour is equivalent to calling application:set_env/4 individually for each application/key combination, except it is more efficient. set_env/1,2 warns about duplicated applications or keys. The warning is also emitted during boot, if applications or keys are duplicated within one configuration file, e.g. sys.config. OTP-15662 Application(s): kernel *** POTENTIAL INCOMPATIBILITY *** Handler specific configuration parameters for the standard handler logger_std_h are changed to be more intuitive and more similar to the disk_log handler. Earlier there was only one parameter, type, which could have the values standard_io, standard_error, {file,FileName} or {file,FileName,Modes}. This is now changed, so the following parameters are allowed: type = standard_io | standard_error | file file = file:filename() modes = [file:mode()] All parameters are optional. type defaults to standard_io, unless a file name is given, in which case it defaults to file. If type is set to file, the file name defaults to the same as the handler id. The potential incompatibility is that logger:get_config/0 and logger:get_handler_config/1 now returns the new parameters, even if the configuration was set with the old variant, e.g. #{type=>{file,FileName}}. OTP-15663 Application(s): kernel The new configuration parameter file_check is added to the Logger handler logger_std_h. This parameter specifies how long (in milliseconds) the handler may wait before checking if the log file still exists and the inode is the same as when it was opened. The default value is 0, which means that this check is done prior to each write operation. Setting a higher number may improve performance, but adds the risk of loosing log events.
