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.

Smoke tests are meant to verify that a build of erlang has been successfull.

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}]).

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
