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.

2013-09-06Convert some notes.xml files from latin-1 to utf-8Björn Gustavsson
In the master branch, the encoding for most xml files have been changed from latin-1 to utf-8. The problem is, that the corresponding files in the maint branch still are encoded in latin-1, and that a merge from maint to master may bring in characters encoded in latin-1 into a notes.xml file declared to be in utf-8. To fix the problem once and for all (for the files involved), we'll need to re-encode the files files utf-8 in maint, and then merge to master. Noticed-by: Magnus Henoch

* sv-sched-percentage-option: add erl option to set schedulers by percentages OTP-11282
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.

2013-08-07erts: Fix race in ptab that can cause PID mix-upsSverker Eriksson
Since: R16B01 Symptom: A spawned process may get the same PID as an existing process. The new process will "steal" the PID and make the old process unreachable through the PID. The problem also applies to port identities but has only been seen for processes. Conditions: SMP emulator with at least two scheduler threads. Rapid spawning and termination of a large number of processes. A small number of free slots in the process table will also increase the risk for this bug. Workaround: Use command line options "+P legacy" and "+Q legacy" Cause: The race happens if a process terminates and gets stalled while releasing its process table slot. The stall has to be so long (due to OS preemptive scheduling most probably) for other schedluer threads to consume all other free slots for newly spawn processes. Fix: Write invalid-markers in the free-pid-table and do atomic exhange operations in retry-loops to make sure each thread gets a unique PID.
