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.

2011-09-29Double timeout to make sure debug builds passLukas Larsson
2011-09-29Use now instead of os:timestampLukas Larsson
This is done in order to improve timing when testing debug builds, especially ppc debug builds.

Code area allocation was done twice; first in read_code_header() and then in erts_make_stub_module() itself.

2011-09-27distribution_SUITE: Use unique slave node namesBjörn Gustavsson
bad_dist_ext_connection_id/1 used the same names for the slave nodes as bad_dist_ext_receive/1, which would cause it to fail if bad_dist_ext_receive/1 failed.

Add an end_per_testcase/2 function to ensure that the process with the name 'busy_drv_server' has been killed before the next test case attempts to register a process with the same name.

2011-09-26erl_prim_loader: Eliminate dialyzer warningBjörn Gustavsson
The concat/1 function is now only used to append lists when constructing filenames. Thus it is too general and the first clause (that handles characters) will never be used. We could just remove the clause that is never used, but then the name 'concat' would be misleading and someone could use misuse it. Therefore, replace concat/1 with the join/2 function that can only be used for joining filename components.

2011-09-22Fix lost wakeup of scheduler when enqueuing auxiliary workRickard Green
When auxiliary work was enqueued on a scheduler, the wakeup of the scheduler in order to handle this work could be lost. Wakeups in order to handle ordinary work were not effected by this bug. The bug only effected runtime systems with SMP support as follows: * Deallocation of some ETS data structures could be delayed. * On Linux systems not using the NPTL thread library (typically ancient systems with kernel versions prior to 2.6) and Windows systems, the {Port, {exit_status, Status}} message from a terminating port program could be delayed. That is, it only effected port programs which had been started by passing exit_status as an option to open_port/2.

2011-09-20Fix build problems on MacOS 10.7 (Lion)Björn Gustavsson
On MacOS 10.7 (Lion) with Xcode 4.1 installed, the default C compiler is llvm-gcc-4.2. That compiler compiles beam_emu.c incorrectly, resulting in an emulator that will not start. The problem can be worked around by turning off all optimizations, but that will significantly degrade the performance of the run-time system. The problem can also be worked around manually like this: CC=gcc-4.2 ./configure To allow a working system to be built "out of the box", have the configure script set up the emulator Makefile so that gcc-4.2 will be used to compile beam_emu.c if the default compiler is llvm-based. All other C files will still be compiled with the default compiler.
