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.

Running some valgrind memory checking showed the error below:
==18040== Thread 6:
==18040== Source and destination overlap in memcpy(0xf3f3f04, 0xf3f3f08, 52)

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.

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.
|
|
|
|
Faulty utf8 atoms are rejected anyway later when the atom is created.
|
|
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.
|
|
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().

Make port close not be delayed
Be less eager requesting wakeup for cleanup jobs
|
|
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.

Make sure each fix allocator type always allocate the right fixed size.

Bug will (as it seems) only result in faulty statistics.

* lukas/erts/efile_delayed_write_fix/OTP-10984:
Do driver_deq in worker threads instead of async_ready
|
|
|
|
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.
