2013-04-22Fix src/dest overlap in ttsl driverLukas Larsson
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.

These were documented in the stdlib user's guide, but not in the reference manual for erl. This has now been corrected.
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.

* 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.

2013-04-04Fixed documentation for priority_level to spawn_optFredrik Gustafsson
2013-04-04Consistent definition of priority levelsKostis Sagonas
In the specs and the documentation of the spawn_opt family of functions there is the following definition of priority levels: Level = low | normal | high However, the process_flag/1 function in that module reads: process_flag(Flag :: priority, Level) -> OldLevel Types: Level = OldLevel = priority_level() priority_level() = low | normal | high | max This is clearly inconsistent. Change specs to use the process_level() type declaration instead of re-defining it in various places.

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.
