2013-09-25Implement platform specific aligned sys_alloc and use when supportedRickard Green
erts_sys_aligned_alloc() is currently implemented using posix_memalign if it exist, or using _aligned_malloc on Windows. If erts_sys_aligned_alloc() exist allocators will create sys_alloc carriers similar to how this was done pre-R16.
2013-09-24add system_info(ets_limit)Steve Vinoski
Add system_info(ets_limit) to provide a way to retrieve the runtime's maximum number of ETS tables. Add tests and documentation for it too. Also repair the alphabetical order of system_info/1 argument descriptions in the documentation and in the erlang.erl clauses. Add new preloaded erlang.erl due to that change. Also ensure all system_info/1 clauses are represented in the erlang.xml source documentation -- a couple had been inadvertently dropped in previous commits when other clauses were added.
2013-09-20Check all pattern arguments passed to binary:matches/2Mike Sassak
Including an empty binary as one of multiple patterns passed to binary:matches/2 would crash BEAM with: "Cannot reallocate 1342177280 bytes of memory (of type "tmp")". This ensures each pattern is valid before trying to match.
2013-09-11Fix syslog definesMatt Lewandowsky
config.h defines HAVE_SYSLOG_H whereas the sources are looking for NO_SYSLOG to be undefined. As the logic of "if feature is available" makes more sense than "if feature is not unavailable", I opted for the config.h define.

2013-09-09Fix incorrect values returned by integer_to_binary/2Juan Jose Comellas
When integer_to_binary/2 receives 0 or a negative number as an argument with a base that is different from 10, it will return incorrect values (<<>> in the case of 0) or it will crash (with negative numbers). This commit fixes these problems and adds tests to cover these cases.

2013-08-29add erl option to set schedulers by percentagesSteve Vinoski
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. Add documentation for the +SP option. Add tests for the +SP option to scheduler_SUITE. Add tests and documentation for two existing features of the +S option: +S 0:0 resets the scheduler thread count and scheduler threads online count to their defaults, and specifying negative numbers for +S results in those values being subtracted from the default values for the host.
2013-08-27erts: Fix segfault when scheduling release_port later_opLukas Larsson
begin_port_cleanup can be called from a non-scheduler thread, this means that there is no esdp available and thus erts_schedule_thr_prgr_later_op segfaults.
2013-08-23Create better distribution of files over async threadsPatrik Nyblom
The actual port id is used to create a key from the pointer value which is the ErlDrvPort. To do this a new driver api function driver_async_port_key is added and the driver API minor version is updated. The documentation is updated and the faulty description of how to spread ports over async threads is updated to use the new API. Testcase also added.
