<p>This document describes the changes made to the ERTS application.</p>

<section><title>Erts 5.8.4</title>

<section><title>Fixed Bugs and Malfunctions</title>
<list>
<item>
<p>Fix binary and iolist overflow problems. Typically
problems arose in length calculation where the result
would exceed (1 bsl 32 - 1).</p>
<p>
Own Id: OTP-9118</p>
</item>
<item>
<p>
Using the old erlang shell (i.e. erl instead on werl) on
windows and doing several init:restart's would eventually
hang the VM. That is no longer the case.</p>
<p>
Own Id: OTP-9139</p>
</item>
<item>
<p>
Removed recursive C code when printing Erlang terms to
buffers, avoiding stack overflows that could cause VM to
crash.</p>
<p>
Own Id: OTP-9140</p>
</item>
<item>
<p>
The send_timeout option in gen_tcp did not work properly
in active mode or with {active,once} options. This is now
corrected.</p>
<p>
Own Id: OTP-9145</p>
</item>
<item>
<p>
Fixed various typos across the documentation (Thanks to
Tuncer Ayaz)</p>
<p>
Own Id: OTP-9154</p>
</item>
<item>
<p>Remove duplicate stack entries which could occur after
calling certain BIFs.</p>
<p>
Own Id: OTP-9163</p>
</item>
<item>
<p>
A race when starting two nodes simultaneously using
run_erl has been removed.</p>
<p>
Own Id: OTP-9164</p>
</item>
<item>
<p>
Add documentation on .erlang processing back again
(Thanks to Gabor Liptak)</p>
<p>
Own Id: OTP-9189</p>
</item>
<item>
<p>
Remove gratuitous paren in driver_entry(Thanks to Tuncer
Ayaz)</p>
<p>
Own Id: OTP-9192</p>
</item>
<item>
<p>
Fix some wrong pointer dereferences (Thanks to Cristian
Greco)</p>
<p>
Own Id: OTP-9194</p>
</item>
<item>
<p>
erts: Remove unused variables (Thanks to Tuncer Ayaz)</p>
<p>
Own Id: OTP-9205</p>
</item>
<item>
<p>
The documentation for <c>init:get_args/0</c> has been
removed. <c>init:get_args/0</c> itself was deprecated in
R9C and removed in R12B. (Thanks to Eric Pailleau.)</p>

<p>
Allow user to specify the IP address epmd binds to</p>
<p>
The IP address(es) epmd binds to can now be specified by
the user, either via epmd's new "-address" option or (if
that's not used) by setting the environment variable
ERL_EPMD_ADDRESS. Multiple addresses may be specified
using a comma-separated list. If the loopback address is
not in this list, it will be added implicitly, so that
the daemon can be queried by an interactive epmd
process.(Thanks to Holger Weiß)</p>
<p>

<p>
epmd: include host address in local access check</p>
<p>
In FreeBSD jails, the source and destination address of
connections to localhost are changed to be the IP address
of the jail. Consider connections from the host's IP
address to itself (e.g., the source and destination
address match) to be local for the access control checks.
(Thanks to Michal Santos and Tom at diogunix.com)</p>

Fix list returned by net_kernel:epmd_module</p>
<p>
Function epmd_module of net_kernel returns a list instead
of an atom, when the epmd_module-flag is used. (Thanks to
Markus Knofe)</p>
<p>
Own Id: OTP-9215</p>
</item>
<item>
<p>
Fix epmd's dbg_perror() output</p>
<p>
The dbg_perror() function now hands the current errno
value over to dbg_gen_printf(). This fixes the problem
that errno had been reset to zero by the time it was used
(to print the corresponding error message) in the
dbg_gen_printf() function. (Thanks to Holger Weiß)</p>

<p>
heart: remove garbage appended to heart command</p>
<p>
heart:get_cmd/0 is documented to return an empty string
if the command is cleared. get_cmd/0 returns 2 extra
bytes: 1 byte for the trailing null, 1 byte from the op
(the op is an unsigned char and 2 bytes are allocated for
it in the returned buffer). (Thanks to Michael Santos)</p>

file: fix hang reading compressed files</p>
<p>
The gzio driver goes into an infinite loop when reading
past the end of a compressed file. Reported-By: Alex
Morarash (Thanks to Michael Santos)</p>

<p>Eliminate alias warnings from gcc 4.5.2</p>
<p>
Own Id: OTP-9250</p>

<p>
Unsigned integer may overflow in error message (Thanks to
Michael Santos)</p>
<p>
Own Id: OTP-9251</p>

<item>
<p>
Driver names should be strings, not atoms</p>
<p>
Own Id: OTP-9253</p>
</item>
<item>
<p>
driver_entry: Remove gratuitous paren and fix typo
(Thanks to Tuncer Ayaz)</p>
<p>
Own Id: OTP-9254</p>
</item>
<item>
<p>
Fix format specifiers in erl_exit messages</p>
<p>
Fix an error message by using an unsigned integer
specifier as seen in a tweet by @metabrew: #erlang VM
crashed with "no next heap size found: -2090496108,
offset 0", suddenly allocated all available RAM</p>
<p>
Also correct mis-typed string formats in bif.c.(Thanks to
Michael Santos)</p>
<p>
Own Id: OTP-9262</p>

<p>
net_drv: remove unused tcp request id inet_drv: remove
gratuitous assignment (Thanks to Tuncer Ayaz)</p>
<p>
Own Id: OTP-9263</p>
</item>
<item>
<p>
Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling
flow control</p>
<p>
Flow control can cause unwanted behaviour of the beam
process, if accidentally hit Ctrl-S (instead of Ctrl-D to
detach) the entire beam may be blocked.</p>
<p>
Fix this problem by making it possible to turn off flow
control by setting the environment variable
RUN_ERL_DISABLE_FLOWCNTRL. (Thanks to Jonas Faklkevik)</p>

<item>
<p>The following bugs due to missing memory barriers have
been fixed:</p> <list> <item><p> ETS tables using the
<c>write_concurrency</c> option could potentially get
into an internally inconsistent state. </p></item>
<item><p> ETS tables using the <c>ordered_set</c> option
could potentially get into an internally inconsistent
state. </p></item> <item><p> A number of memory barriers
have been added when building with the
<c>libatomic_ops</c> API (i.e. when passing
<c>--with-libatomic_ops=PATH</c> to <c>configure</c>) and
the tilera atomics API (i.e. when building for the tilera
chip). Note that these bugs were due to erroneous usage
of the APIs, and not in the implementations of the APIs.
When using these APIs the following bugs where
present:</p> <list> <item><p> The BIF
<c>erlang:ports/0</c> could return an erroneous result.
</p></item> <item><p> A thread blocking other threads
during code loading, or setup of tracing could
potentially read invalid data. </p></item> <item><p>
Fixation of ETS tables could potentially get into an
internally inconsistent state. </p></item> </list>

Fix halfword bug for ETS ordered_set when doing
<c>select/match</c> with partly bound key.</p>
<p>
Own Id: OTP-9292</p>
</item>
<item>
<p>
Fix bug in <c>code:is_module_native</c> that caused crash
for deleted modules.</p>
<p>
Own Id: OTP-9298</p>
</item>
<item>
<p>
Calling <c>driver_async_cancel()</c> could cause a
scheduler thread to enter an eternal loop doing no useful
work. (Thanks to Anders Ramsell)</p>

<section><title>Improvements and New Features</title>

<p>
New <c>enif_is_exception function</c> to allow NIFs to
determine whether an <c>ERL_NIF_TERM</c> represents an
exception. (Thanks to Steve Vinoski)</p>
<p>
Own Id: OTP-9150</p>
</item>
<item>
<p>
A process being garbage collected by another process
could be scheduled on another scheduler. This prevented
this scheduler from doing any useful work until the
garbage collection was done. This either occurred due to
a explicit call to the <c>garbage_collect/1</c> BIF, or
due to a garbage collection part of code loading. A
process being garbage collected like this will now not be
scheduled until the garbage collection has completed.</p>

Remove unnecessary validation copy in
prim_file:drv_command/3 (Thanks to Tony Rogvall)</p>

<item>
<p>
Symbolic link handling on windows have been slightly
updated to map error conditions more consequently and
correctly read directory links created outside of the
Erlang environment.</p>
<p>
Own Id: OTP-9279</p>
</item>
<item>
<p>
Due to standard library DLL mismatches between versions
of OpenSSL and Erlang/OTP, OpenSSL is now linked
statically to the crypto driver on Windows. This fixes
problems starting crypto when running Erlang as a service
on all Windows versions.</p>
<p>
Own Id: OTP-9280</p>
</item>
<item>
<p>Halfword emulator memory handling improvements:</p>
<list> <item><p>Much more of internal memory structures
have been made able to use "high" memory and are no
longer restricted to the 4Gb limit that still applies for
all process heap data.</p> </item> <item><p>Fixed faulty
values from <c>erlang:memory()</c> caused by 32-bit
counter overflow.</p> </item> <item><p>New counter
<c>low</c> in <c>erlang:memory()</c> that sums up all
memory restricted by 4Gb limit.</p> </item> </list>
<p>

<p>
The value set in the undocumented and unsupported
ERL_version_FLAGS (e.g. ERL_R14B03_FLAGS) environment
variable can now be overridden by the command line
(similar to ERL_AFLAGS).</p>
