This document describes the changes made to the ERTS application.

+
Erts 5.10.4 + +
Fixed Bugs and Malfunctions + + +

+ 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.

+ + +

+ Fixed syslog defines and defined LOG_ERR for systems + without syslog.h. Thanks to Matt Lewandowsky.

+

+ + +

+ Check all pattern arguments passed to binary:matches/2. + Thanks to Mike Sassak.

+

+ Own Id: OTP-11350

+ + +

+ Fix two small silent rules omissions. Thanks to Anthony + Ramine.

+ + +

+ 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.

+ + +

+ Fix bsr bug occurring when shifting a huge number a huge + number of bits to the right. Thanks to Lars Hesel + Christensen.

+ + +

+ Fix memory leak for distributed monitors

+

+ Own Id: OTP-11410

+ + +

+ Fix various typos in erts, kernel and ssh. Thanks to + Martin Hässler.

+ Own Id: OTP-11414

+ + +

+ 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.

+

+ + +

+ 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.

+

+ Own Id: OTP-11450

+ + +

+ Threads other than schedulers threads could make thread + unsafe accesses when support for migration of memory + carriers had been enabled, i.e., when the +M<S>acul + 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.

+

+ Own Id: OTP-11456 Aux Id: OTP-10279

+ + +

+ Fix bug in binary_to_term for invalid bitstrings + and very large binaries (>2Gb).

+

+ Own Id: OTP-11479

+ + +

+ 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.

+

+ Own Id: OTP-11491

+ + +

+ 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.

+

+ Own Id: OTP-11496

+ + +

+ Fix benign bugs regarding bitstring compare. Only a + nuisance for debug and valgrind VM.

+

+ Own Id: OTP-11501

+ + +

+ Silence warnings (Thanks to Anthony Ramine)

+

+ Own Id: OTP-11517

+ + +

+ 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.

Improvements and New Features + + +

+ 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 <size in + MB> 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.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+ + +

+ Added erlang:system_info(ets_limit) to provide a way to + retrieve the runtime's maximum number of ETS tables. + Thanks to Steve Vinoski

+

+ Own Id: OTP-11362

+ + +

+ Add new BIF os:unsetenv/1 which deletes an environment + variable. Thanks to Martin Hässler.

+ + +

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.
