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.

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}]).

2013-07-29Bailout if no native implementations are foundLukas Larsson
Some basic tests are already done in configure. This makes sure we cover all cases by bailing out when compiling as well.

* 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.
2013-07-18Fix compile error on ARM and GCC < 4.1.0Johannes Weißl
Since b29ecbd (OTP-10418, R15B03) Erlang does not compile anymore with old versions of GCC that do not have atomic ops builtins on platforms where there is no native ethread implementation (e.g. ARM): In file included from ../include/internal/gcc/ethread.h:29, from ../include/internal/ethread.h:354, from beam/erl_threads.h:264, from beam/erl_smp.h:27, from beam/sys.h:413, from hipe/hipe_mkliterals.c:29: ../include/internal/gcc/ethr_membar.h:49:4: error: #error "No __sync_val_compare_and_swap" This patch adds a header guard in "gcc/ethread.h", as is present in "libatomic_ops/ethread.h".
