--- asn1 ------------------------------------------------------------
OTP-5302 A bug due to representation of open_type values is now fixed.
It could cause problem if one used the EXTERNAL type.
OTP-5378 Due to an internal error the same code could have been
generated more than one time. This happened for the exclusive
deocode functionality.
--- compiler ------------------------------------------------------------
OTP-5404 In rare circumstances, inccorrect code for record or tuple
access could be generated. The incorrect code would either
trigger an internal error in the compiler or cause an
exception at run time. (Thanks to Martin Bjorklund.)
Corrected a bug in in bit syntax matching where clauses
could match in the wrong order. (Thanks to Ulf Wiger.)
OTP-5436 Complex functions could cause the internal validator in the
compiler to generate an internal error even though the
generated code was correct.
--- erl_interface ------------------------------------------------------------
OTP-5456 A configuration test error caused erl_interface to be built
without support for threads. This has been corrected.
--- erts ------------------------------------------------------------
OTP-5388 The c option for the +B flag has been introduced which makes
it possible to use Ctrl-C (Ctrl-Break on Windows) to
interrupt the shell process rather than to invoke the
emulator break handler. All new +B options are also supported
on Windows (werl) as of now. Furthermore, Ctrl-C on Windows
has now been reserved for copying text (what Ctrl-Ins was
used for previously). Ctrl-Break should be used for break
handling. Lastly, the documentation of the system flags has
been updated.
OTP-5420 If a process had node links (created by monitor_node/2),
excuting process_info(Pid, memory) for that process would
crash the emulator.
OTP-5428 Minor corrections to the help text printed by 'erlc -help'.
The documentation for erlc was also slightly updated.
OTP-5430 32-bit words were used for offsets in the garbage collector.
This caused the emulator to crash on 64-bit machines when
heaps were moved more than 4 GB during garbage collection.
OTP-5448 is_boolean(42.5) failed to load if optimization was
explicitly turned off.
OTP-5450 If there was a call to Module:foo/X from any loaded module,
the returned by M:module_info(exports) would always include
{foo,X} (even though Module:foo/X if was not defined).
--- hipe ------------------------------------------------------------
OTP-5463 The hipe application is now included in the Windows binary
package, so that Dialyzer can be used.
OTP-5469 The type analyzer in the hipe application has been updated to
eliminate some false warnings in Dialyzer.
--- ic ------------------------------------------------------------
OTP-5375 In C back-ends, the compiler crashed when generating C code
for error reports when a scoped name was used as a type in a
union.
--- inets ------------------------------------------------------------
OTP-5380 Sometimes EWS modules where called with an Info record where
the peername field was {-1, "unknown"}. This could happen
when a client was making a lot of requests which it discards
before they where answered by the server. The server now
ignores such requests and does not call the EWS modules in
this case.
OTP-5409 The HTTP-server now returns the 408 status code upon a
request timeout as expected instead of the previous faulty
behavior of sending a 500 status code.
OTP-5410 The content length was put in to the HTTP-headers as an
integer instead of as a string.
OTP-5411 It was wrongly presumed that code:priv_dir would always be
writable due to how the test-server works. The directory is
now a configuration parameter in the inets-application
configuration file. Failing to configure it will result in
that all cookies are treated as session cookies.
OTP-5419 An undocumented beta version of tftp is included.
OTP-5443 Tunneling of SSL through a proxy has now been implemented.
However, due to lack of test sites, this has only partially
been verified, it is likely that there will have to be
future improvements in this area.
OTP-5442 The pipeline timeout was changed to be zero by default to
avoid that people by accident would create connection
processes that never die and eat up the socket resources.
*** POTENTIAL INCOMPATIBILITY ***
OTP-5444 Altered the way spawn_link is used in mod_esi to avoid
getting, in this senario, unwanted error reports from
spawn_link. (The behavior of spawn_link was altered in a
not backwards compatible way.)
OTP-5453 When further testing the functionality of https requests that
goes through a proxy. We realised that alas this can not
currently be supported as it requires features from the ssl
implementation that is not currently available. So for now an
error message will be returned when trying to use this
functionality.
OTP-5454 When trying to get a url from a server that does not exist
the client hanged instead of returning an error message. Bug
introduced in inets-4.3.
--- kernel ------------------------------------------------------------
OTP-5374 net_kernel:monitor_nodes/2 which takes a flag and, an option
list has been added. By use of net_kernel:monitor_nodes/2 one
can subscribe for nodeup/nodedown messages with extra
information. It is now possible to monitor hidden nodes, and
get nodedown reason. See the net_kernel(3) documentation for
more information.
OTP-5388 The c option for the +B flag has been introduced which makes
it possible to use Ctrl-C (Ctrl-Break on Windows) to
interrupt the shell process rather than to invoke the
emulator break handler. All new +B options are also supported
on Windows (werl) as of now. Furthermore, Ctrl-C on Windows
has now been reserved for copying text (what Ctrl-Ins was
used for previously). Ctrl-Break should be used for break
handling. Lastly, the documentation of the system flags has
been updated.
OTP-5391 Documentation for erlang:binary_to_float/1 deleted. The
BIF itself was removed several releases ago. Updated
documentation for apply/2 and apply/3.
OTP-5406 The possibility to start the erlang shell in parallell with
the rest of the system was reintroduced for backwards
compatibility in stdlib-1.13.1. The flag to be used for this
is now called async_shell_start and has been documented. New
shells started from the JCL menu are not syncronized with
init anymore. This makes it possible to start a new shell
(e.g. for debugging purposes) even if the initial shell
hasn't come up.
--- megaco ------------------------------------------------------------
OTP-5401 Pending limit cleanup error's. In some situations (high load),
reply-records where never removed, blocking new requests with
the same transaction id.
OTP-5446 Added utility functions to retrieve some system and application
info, see versions1 and versions2.
OTP-5446 When the enable_trace function is called with the File argument,
it sets up dbg so that trace events are written as plain text
to the given file (using io:format).
Incompatibilities:
OTP-5446 The File argument to the function enable_trace no longer sets up
dbg to write the trace events directly to file but instead to be
written to a plain text file using io:format.
Also enable_trace no longer accepts the argument {io, Verbosity}.
Fixed bugs and malfunctions:

--- observer --------------------------------------------------------
OTP-5408 The crashdump viewer is faster when showing message,
dictionary, and stack dump for large processes.
--- odbc -----------------------------------------------------------
OTP-5437 Odbc now uses configure as all "normal" applications instead
of providing special Makefiles for each commercial supported
platform. This also makes it easier to build odbc on non
supported platforms.
--- os_mon ----------------------------------------------------------
OTP-5421 memsup.c will now compile on OpenBSD. (Thanks to Geoff White
and Jay Nelson.)
The disksup and cpu_sup modules now work on Mac OS X (tested
on Mac OS 10.3.8).
The memsup module should now work on Linux 2.6.* as well as
on older Linuxes. (The format of /proc/meminfo has slightly
different formats in different releases of Linux.)
--- parsetools ------------------------------------------------------
OTP-5461 A bug in Yecc that was introduced in R9B has been removed.
Another bug concerning precedence declaration "one level up"
has been fixed.
--- snmp ------------------------------------------------------------
OTP-5390 [agent] Export utility function to create agent config files.
OTP-5423 [agent] Documented instrumentation utility functions (e.g.
snmpa:current_request_id/0).
Reported Fixed Bugs and Malfunctions:
OTP-5370 [manager] If the client crashes after having issued an async request,
the server will crash when trying to perform cleanup.
OTP-5394 Failure to convert an audit-trail-log to textfile when using
the default log name.
OTP-5414 [manager] Corrected the discovery handling of the manager.
OTP-5415 [manager] Manager statistics counter creation correction.
OTP-5424 [agent] When using the old style agent configuration (pre 4.0), it
was not possible to specify a different error report module
(the agent allways choose snmpa_error_logger). A similar
problem existed for the config option force_config_load,
which allways reverted to false.
OTP-5431 [manager] The manager net_if process failed to properly handle the case
bind_to option value true.
OTP-5433 [agent] Various minor mnesia-related fixes. "Martin Bjorklund"
<mbj@nortel.com>
OTP-5441 [manager] Missing interface functions for loading and
unloading mibs into/from the manager.
OTP-5445 Added utility functions to retrieve some system and
application info, see versions1/0 and versions2/0.
--- stdlib ----------------------------------------------------------
OTP-5402 Closing a Dets table kept in RAM would cause a crash if the
file could not be written. This problem has been fixed by
returning an error tuple.
OTP-5406 The possibility to start the erlang shell in parallell with
the rest of the system was reintroduced for backwards
compatibility in stdlib-1.13.1. The flag to be used for this
is now called async_shell_start and has been documented. New
shells started from the JCL menu are not syncronized with
init anymore. This makes it possible to start a new shell
(e.g. for debugging purposes) even if the initial shell
hasn't come up.
OTP-5412 erl_pp now correctly pretty-prints 'fun F/A'.
OTP-5425 The compiler will now produce warnings when using the
deprecated functions in the snmp module.
OTP-5432 The function c:zi/0 has been removed. Use c:i/0 instead.
OTP-5435 The Erlang shell failed if the compiler was not in the code
path. This problem has been fixed, but in order to evaluate
records the compiler is still needed.
OTP-5452 Corrected the example in the documentation for ets:match/2.
Also clarified that ets:update_counter/3 updates the counter
atomically. (Thanks to Anders Svensson.)
OTP-5462 Corrected two minor bugs found by the Dialyzer: Calling a
parameterized module from a restricted shell (i.e. if
shell:start_restricted/1 has been used) would crash the shell
evaluator. A debug printout in gen_fsm had a clause that
would never match; causing less information to be printed.
And a somewhat more serious one also found by Dialyzer:
rpc:yield/1 would crash unless the call started by
rpc:async_call/4 had already finished; rpc:nb_yield(Key,
infinity) would also crash.
Cleaned up and removed redundant code found by Dialyzer in
erlang:dmonitor_p/2.
--- tools -----------------------------------------------------------
OTP-5418 The cover tool could not analyze empty modules on module
level.
