There is one remaining bug where ttsl_drv's state ends up inconsistent with the terminal own state; when a wide character is entered on the last column of the terminal. Reported-by: Loïc Hoguin

2013-04-21fix valgrind error in erts/emulator/drivers/unix/ttsl_drv.cSteve Vinoski
Running some valgrind memory checking showed the error below: ==18040== Thread 6: ==18040== Source and destination overlap in memcpy(0xf3f3f04, 0xf3f3f08, 52) ==18040== at 0x4C2CFA0: memcpy@@GLIBC_2.14 (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==18040== by 0x5CF527: del_chars (ttsl_drv.c:845) ==18040== by 0x5CED5E: ttysl_from_erlang (ttsl_drv.c:658) ==18040== by 0x4982E3: erts_write_to_port (io.c:1235) ==18040== by 0x49A2BD: erts_port_command (io.c:2223) ==18040== by 0x48C054: do_send (bif.c:1962) ==18040== by 0x48CB6E: erl_send (bif.c:2162) ==18040== by 0x566599: process_main (beam_emu.c:1665) ==18040== by 0x4B1A95: sched_thread_func (erl_process.c:4834) ==18040== by 0x6075E2: thr_wrapper (ethread.c:106) ==18040== by 0x5560E99: start_thread (pthread_create.c:308) This occurred on Linux using R15B01 while the shell was emitting a prompt, but the same problem is still present in R16B. Change the memcpy on line 845 of ttsl_drv.c to memmove as valgrind suggests. After the change, verify with valgrind that the error no longer occurs.

2013-04-17Encode Erlang source files with non-ascii characters in UTF-8Björn Gustavsson
To ensure that 'master' compiles when we merge 'maint' to it, regardless of which encoding is default in 'master', all source files with non-ascii characters *must* have the encoding specified.

2013-04-15erts: Remove unnecessary utf8 analysis step in external decodingSverker Eriksson
Faulty utf8 atoms are rejected anyway later when the atom is created.
2013-04-15erts: Fix locking order violation for allocation wrappersSverker Eriksson
Some query functions in erl_alloc_util.c lock the allocator mutex and then use erts_printf that in turn may call the sys allocator through the wrappers. To avoid breaking locking order these query functions first "pre-locks" all allocator wrappers.
2013-04-11erts: Change locking order for "port_table" and "port_sched_lock"Sverker Eriksson
Keep order between the two but move them before all the allocation locks. Old order violated for "port_table" lock in ptab_list_bif_engine().

* rickard/thr_prgr_later_op/OTP-10994: Make port close not be delayed Be less eager requesting wakeup for cleanup jobs
2013-04-04Make port close not be delayedPatrik Nyblom
Drivers are dereferenced when the port is completely gone, in the operation scheduled with erts_schedule_thr_prgr_later_op. If we use erts_schedule_thr_prgr_later_cleanup_op, it may not happen for a long time and the driver can not be unloaded. We can not dereference the driver before the thread_progress_later thing, because references to the driver may exist in other threads, so the unloading of the driver may free locks held by other schedulers and whatnot.

* lukas/erts/efile_delayed_write_fix/OTP-10984: Do driver_deq in worker threads instead of async_ready
2013-03-18Add dependency to dtrace header for parallell makePatrik Nyblom
2013-03-13Do driver_deq in worker threads instead of async_readyLukas Larsson
Doing it in async_ready was needed before the pdl was introduced, but now with the pdl the deq no longer needs the port lock to protect it. This was not an issue when async_ready was called in the worker thread, but now (R15B) that it is signalled back to the scheduler, some very nasty race conditions could occur when using driver_timer and async jobs.
