2011-11-14erlc: Do not bind schedulers when invoking "erl"Björn Gustavsson
If parallel make is used, several instance of 'erlc' is likely to be invoked at once. Therefore, the default binding of schedulers to CPU cores will do no good. (With this change, the build of Erlang/OTP with six threads finished in about 7 minutes; without in about 11 minutes.)

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.

2011-05-11erlexec: Make ERL_<version>_FLAGS behave like ERL_AFLAGSBjörn Gustavsson
The contents of the ERL_<version>_FLAGS undocumented environment variable would be added at the end of the command line passed to the BEAM emualator (similar to ERL_ZFLAGS), making it impossible to override (for example) "-smp" with "-smp disable" on the command line. To allow overriding, put the contents of ERL_<version>_FLAGS at the beginning of the command line (similar to ERL_AFLAGS). Since the ERL_<version>_FLAGS variable is undocumented and unsupported, it is OK to change its behaviour in a minor release.
2011-05-11cerl: Fix several incompatibilities with 'erl'Björn Gustavsson
Invoking 'cerl' like 'cerl -smp' would only start the smp emulator if default was to start the non-smp emulator, otherwise 'erlexec' would try to start 'beam.smp.smp'. Furthermore 'cerl -smp disable' would be handled in the same way as 'cerl -smp'.
2011-05-11Teach erlexec the -emu_name_exit optionBjörn Gustavsson
It is difficult/impossible to find out whether an invocation of 'erl' will start the smp emulator or the non-smp emulator (short of actually starting the emulator). Therefore we will need a way to ask 'erlexec'.
2011-05-11cerl: Remove ancient obsolete optionsBjörn Gustavsson
The -frag and -smp_frag options was used to start an (at the time) experimental build of the emulator. The -shared and -hybrid option was used to start experimental versions of the emulator with alternate heap architectures.
2011-05-02Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling flow controlJonas Faklkevik
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.

2011-02-18Add dependencies Makefile generation to erlc(1) and compile(3)Jean-Sébastien Pédron
This is useful when a project is built with Makefiles and erlc(1) instead of EMakefiles. Tracking dependencies by hand is error-prone and it becomes painful when using external application headers like EUnit's one. A dependencies Makefile will look like this: module.beam: module.erl \ /usr/local/lib/erlang/lib/eunit-2.1.4/include/eunit.hrl \ header.hrl When included in the main Makefile, 'module' will be recompiled only when needed. GCC offers the same feature and new erlc(1) options are compatible with it. More informations at: http://wiki.github.com/dumbbell/otp/dependencies-makefile

2010-12-02Stop using uncertain flags for getaddrinfo()Raimo Niskanen
The AI_V4MAPPED flag is falling out of grace in modern IPv6 stacks, for security reasons, e.g. FreeBSD do not document it any longer. The AI_ADDRCONFIG flag have got unclear semantics on the same OS.
