2013-10-14Merge branch 'fenollp/treewide_remove_unexpected_0xff/OTP-11323' into maintFredrik Gustafsson
* fenollp/treewide_remove_unexpected_0xff/OTP-11323: Remove ^L characters hidden randomly in the code. Not those used in text files as delimiters.
2013-10-10Add bsr test data showing bug when shifting large numbersLars Hesel Christensen
Add test data demonstrating that bsr is broken when shifting a large number a huge number of bits to the right.
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.

files as delimiters. While working on a tool that processes Erlang code and testing it against this repo, I found out about those little sneaky 0xff. I thought it may be of help to other people build such tools to remove non-conforming-to-standard characters.
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.
2013-08-23Create 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.

2013-06-14Fix binary construction on floating point middle-endian machinesJohannes Weißl
This complements 933e701 (OTP-10209). Without this patch the test cases "in_guard/1" and "coerce_to_float/1" in bs_construct_SUITE fail. The added lines in bs_construct_SUITE cover all branches that were not covered before (small and big numbers if BIT_OFFSET(erts_bin_offset) != 0).
2013-06-14Fix binary matching on floating point middle-endian machinesJohannes Weißl
This complements 933e701 (OTP-10209). Without this patch the test case "bs_match_misc_SUITE:t_float/1" fails. Simple error example: 1> <<_,_,_,_,_,_,_,_>> = <<1.25/float>>. <<63,244,0,0,0,0,0,0>> 2> <<1.25/float>> = <<63,244,0,0,0,0,0,0>>. ** exception error: no match of right hand side value <<63,244,0,0,0,0,0,0>> The additional test case is added because in a former version of this patch the ERTS_FP_ERROR_THOROUGH check for NaN/infinity was mistakenly applied on the still word-switched double.
2013-06-14Fix external term format BIFs on floating point middle-endian machinesJohannes Weißl
This complements 933e701 (OTP-10209). Simple error example: 1> <<131,70,63,240,0,0,0,0,0,0>> = term_to_binary(1.0, [{minor_version,1}]). ** exception error: no match of right hand side value <<131,70,0,0,0,0,63,240,0,0>> 2> 1.0 = binary_to_term(<<131,70,63,240,0,0,0,0,0,0>>). ** exception error: no match of right hand side value 5.299808824e-315 But roundtrip always works: 3> 1.0 = binary_to_term(term_to_binary(1.0, [{minor_version,1}])). 1.0
