2013-07-30Change default of erlang:halt/2 to the documentedPatrik Nyblom
Bug reported by Jose Valim on the erlang-bugs mailing list: erlang:halt(0,[]) does not flush as advertised in the documentation. Should be the same as erlang:halt(0,[{flush,true}]), but is in fact the same as erlang:halt(0,[{flush,false}]).

* sze/to_erl/OTP-11206: Fix changing terminal parameters in to_erl
2013-07-22Fix changing terminal parameters in to_erlStefan Zegenhagen
One of our devices does not like 'to_erl' to be run over a serial port. When to_erl is started, we see "Attaching to /tm<0xFF>" being printed and the device then refuses to accept any input. Occasionally, we have seen a linux kernel error message "serial8250: too much work for irq16" simultaneously. After some debugging we found out that cause is a call to tcsetattr() by to_erl, immediately preceeded by some printf(). The UART in our device doesn't like hardware parameters to be changed while output is concurrently active. In fact, the GNU libc manual also mentions that it might be dangerous to change UART hardware parameters when a transmission is ongoing. The patch attached to this e-mail changes the behaviour of to_erl to use TCSADRAIN instead of TCSANOW when changing terminal parameters. This makes the serial driver wait for the output queues to be empty before applying the terminal parameter change.

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 erlang:phash2() on floating point middle-endian machinesJohannes Weißl
This complements 933e701 (OTP-10209). Without this patch the test case "hash_SUITE:test_phash2/1" fails. Simple error example: 1> 77147068 = erlang:phash2(1.0). ** exception error: no match of right hand side value 50524433
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

* rickard/+sfwi/OTP-11164: erts: Add the +sfwi system flag
2013-06-11erts: Add the +sfwi system flagRickard Green
+sfwi Interval Set scheduler forced wakeup interval. All run queues will be scanned each Interval milliseconds. While there are sleeping schedulers in the system, one scheduler will be woken for each non-empty run queue found. An Interval of zero disables this feature, which also is the default. This feature has been introduced as a temporary workaround for lengthy executing native code, and native code that do not bump reductions properly in OTP. When these bugs have be fixed the +sfwi flag will be removed.
