+ + +

+ Fix changing terminal parameters in to_erl

+

+ Change the behaviour of to_erl to use TCSADRAIN instead + of TCSANOW when changing terminal parameters. This makes + the serial driver wait for the output queues to be empty + before applying the terminal parameter change. Thanks to + Stefan Zegenhagen.

+

+ Own Id: OTP-11206

+ + +

+ The default value of {flush, boolean()} in erlang:halt/2 + is documented to be 'true' if the status is an integer. + The implementation behaviour was reversed. The + Implementation is now corrected to adhere to the + documentation. Thanks to Jose Valim for reporting the + error.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-11218

+ + +

+ Fix serious race bug in R16B01 that could cause PID + mix-ups when a lot of processes were spawned and + terminated in a very rapid pace on an SMP emulator with + at least two scheduler threads.

+

+ Own Id: OTP-11225

+ + +

+ Validating a trace pattern with the option silent no + longer incorrectly enables/disables the silent option of + the calling process.

+

+ Own Id: OTP-11232

+ + +

+ Fixed a bug where GCC 4.8 and later use a more aggressive + loop optimization algorithm that broke some previously + working code in the efile driver. Thanks to Tomas + Abrahamsson for reporting this issue.

+

+ Own Id: OTP-11246

+ + +

+ Fixed bug when printing memory allocator acul option in + crash dump.

+

+ Own Id: OTP-11264

+ + +

+ Opening a new compressed file on Windows could in rare + (random) cases result in {error,eisdir} or other error + codes although it should have succeeded. This is now + corrected.

+

+ Own Id: OTP-11265

+ + +

+ Fixed a race condition when closing a trace port that + would cause the emulator to crash.

+

+ + +
Improvements and New Features + + +

+ There is a new somewhat experimental socket option + 'netns' that can set the network namespace for a socket + on Linux:es where it is supported. See the documentation.

+

+ Own Id: OTP-11157

+ + +

+ New allocator strategy aoffcbf (address order + first fit carrier best fit). Supports carrier migration + but with better CPU performance than aoffcaobf.

+

+ Own Id: OTP-11174

+ + +

+ Introduced functionality for inspection of system and + build configuration.

+

+ Own Id: OTP-11196

+ + +

+ Fix matching of floating point middle-endian machines. + Thanks to Johannes Weissl.

+

+ Own Id: OTP-11201

+ + +

+ Fix compile error on ARM and GCC versions greater than + 4.1.0. Thanks to Johannes Weissl.

+

+ Own Id: OTP-11214

+ + +

+ run_erl: Redirect standard streams to /dev/null. Thanks + to Johannes Weissl.

+

+ Own Id: OTP-11215

+ + +

+ Misc. corrections in documentation for erl_driver. Thanks + to Giacomo Olgeni.

+

+ Own Id: OTP-11227

+ + +

+ Fix documentation regarding binary_part.

+

+ Own Id: OTP-11239

+ + +

+ Make edlin understand a few important control keys. + Thanks to Stefan Zegenhagen.

+

+ Own Id: OTP-11251

+ + +

+ Export type zlib:zstream/0. Thanks to Loic Hoguin.

+

+ Own Id: OTP-11278

+ + +

+ Add erl option to set schedulers by percentages.

+

+ For applications where measurements show enhanced + performance from the use of a non-default number of + emulator scheduler threads, having to accurately set the + right number of scheduler threads across multiple hosts + each with different numbers of logical processors is + difficult because the erl +S option requires absolute + numbers of scheduler threads and scheduler threads online + to be specified.

+

+ To address this issue, add a +SP option to erl, similar + to the existing +S option but allowing the number of + scheduler threads and scheduler threads online to be set + as percentages of logical processors configured and + logical processors available, respectively. For example, + "+SP 50:25" sets the number of scheduler threads to 50% + of the logical processors configured, and the number of + scheduler threads online to 25% of the logical processors + available. The +SP option also interacts with any + settings specified with the +S option, such that the + combination of options "+S 4:4 +SP 50:50" (in either + order) results in 2 scheduler threads and 2 scheduler + threads online.

+

+ Thanks to Steve Vinoski

+ + +

+ Extend erl_driver interface with lock names

+

+ Lock and thread names are already a feature in the driver + interface. This extension will let developers read these + names which eases debugging.

+

+ Own Id: OTP-11303

+ + +

+ Fix incorrect values returned by integer_to_binary/2. + Thanks to Juan Jose Comellas.

+

+ Own Id: OTP-11311

+ + +

+ Fix system_flag scheduling_statistics - disable . Thanks + to Steve Vinoski.

+

+ Own Id: OTP-11317

+ + +

The documentation of predefined types has been + corrected Thanks to Kostis Sagonas.
