This document describes the changes made to the ERTS application.

+
Erts 5.8.4 + +
Fixed Bugs and Malfunctions + + +

Fix binary and iolist overflow problems. Typically + problems arose in length calculation where the result + would exceed (1 bsl 32 - 1).

+

+ Own Id: OTP-9118

+ + +

+ 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.

+

+ Own Id: OTP-9139

+ + +

+ Removed recursive C code when printing Erlang terms to + buffers, avoiding stack overflows that could cause VM to + crash.

+

+ Own Id: OTP-9140

+ + +

+ The send_timeout option in gen_tcp did not work properly + in active mode or with {active,once} options. This is now + corrected.

+

+ Own Id: OTP-9145

+ + +

+ Fixed various typos across the documentation (Thanks to + Tuncer Ayaz)

+

+ Own Id: OTP-9154

+ + +

Remove duplicate stack entries which could occur after + calling certain BIFs.

+

+ Own Id: OTP-9163

+ + +

+ A race when starting two nodes simultaneously using + run_erl has been removed.

+

+ Own Id: OTP-9164

+ + +

+ Add documentation on .erlang processing back again + (Thanks to Gabor Liptak)

+

+ Own Id: OTP-9189

+ + +

+ Remove gratuitous paren in driver_entry(Thanks to Tuncer + Ayaz)

+

+ Own Id: OTP-9192

+ + +

+ Fix some wrong pointer dereferences (Thanks to Cristian + Greco)

+

+ Own Id: OTP-9194

+ + +

+ erts: Remove unused variables (Thanks to Tuncer Ayaz)

+

+ Own Id: OTP-9205

+ + +

+ The documentation for init:get_args/0 has been + removed. init:get_args/0 itself was deprecated in + R9C and removed in R12B. (Thanks to Eric Pailleau.)

+

+ Own Id: OTP-9209

+ + +

+ Allow user to specify the IP address epmd binds to

+

+ 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)

+

+ Own Id: OTP-9213

+ + +

+ epmd: include host address in local access check

+

+ 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)

+

+ Own Id: OTP-9214

+ + +

+ Fix list returned by net_kernel:epmd_module

+

+ Function epmd_module of net_kernel returns a list instead + of an atom, when the epmd_module-flag is used. (Thanks to + Markus Knofe)

+

+ Own Id: OTP-9215

+ + +

+ Fix epmd's dbg_perror() output

+

+ 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)

+

+ Own Id: OTP-9223

+ + +

+ heart: remove garbage appended to heart command

+

+ 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)

+

+ Own Id: OTP-9224

+ + +

+ file: fix hang reading compressed files

+

+ 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)

+

+ Own Id: OTP-9245

+ + +

Eliminate alias warnings from gcc 4.5.2

+

+ Own Id: OTP-9250

+ + +

+ Unsigned integer may overflow in error message (Thanks to + Michael Santos)

+

+ Own Id: OTP-9251

+ + +

+ Driver names should be strings, not atoms

+

+ Own Id: OTP-9253

+ + +

+ driver_entry: Remove gratuitous paren and fix typo + (Thanks to Tuncer Ayaz)

+

+ Own Id: OTP-9254

+ + +

+ Fix format specifiers in erl_exit messages

+

+ 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

+

+ Also correct mis-typed string formats in bif.c.(Thanks to + Michael Santos)

+

+ Own Id: OTP-9262

+ + +

+ net_drv: remove unused tcp request id inet_drv: remove + gratuitous assignment (Thanks to Tuncer Ayaz)

+

+ Own Id: OTP-9263

+ + +

+ Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling + flow control

+

+ 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.

+

+ 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)

+ + +

The following bugs due to missing memory barriers have + been fixed:

ETS tables using the + write_concurrency option could potentially get + into an internally inconsistent state.

+

ETS tables using the ordered_set option + could potentially get into an internally inconsistent + state.

A number of memory barriers + have been added when building with the + libatomic_ops API (i.e. when passing + --with-libatomic_ops=PATH to configure) 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:

The BIF + erlang:ports/0 could return an erroneous result. +

A thread blocking other threads + during code loading, or setup of tracing could + potentially read invalid data.

+ Fixation of ETS tables could potentially get into an + internally inconsistent state.

+ +

+ Own Id: OTP-9281

+ + +

+ Fix halfword bug for ETS ordered_set when doing + select/match with partly bound key.

+

+ Own Id: OTP-9292

+ + +

+ Fix bug in code:is_module_native that caused crash + for deleted modules.

+

+ Own Id: OTP-9298

+ + +

+ Calling driver_async_cancel() could cause a + scheduler thread to enter an eternal loop doing no useful + work. (Thanks to Anders Ramsell)

+

+ Own Id: OTP-9302

+ + +
+ + +
Improvements and New Features + + +

+ New enif_is_exception function to allow NIFs to + determine whether an ERL_NIF_TERM represents an + exception. (Thanks to Steve Vinoski)

+

+ Own Id: OTP-9150

+ + +

+ 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 garbage_collect/1 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.

+

+ Own Id: OTP-9211

+ + +

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

+

+ Own Id: OTP-9276

+ + +

+ 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.

+

+ Own Id: OTP-9279

+ + +

+ 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.

+

+ Own Id: OTP-9280

+ + +

Halfword emulator memory handling improvements:

+

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.

Fixed faulty + values from erlang:memory() caused by 32-bit + counter overflow.

New counter + low in erlang:memory() that sums up all + memory restricted by 4Gb limit.

 +

+ Own Id: OTP-9291 Aux Id: seq11841

+ + +

+ 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).

+ Own Id: OTP-9297
