Test cases that write 4Gb to a file at once would fail on
OS X and FreeBSD.
By running a simple test program on OS X (El Capitan 10.11.4/Darwin
15.4.0), I found that writev() can handle more than 4Gb of data, while
write() only can handle less than 2Gb. (Note that efile_drv.c will use
write() if there is only one element in the io vector, and writev() if
there is more than one.)
It is tempting to attempt to piggy-back on the existing mechanism
for segmenting write operations in efile_drv.c, but because of the
complex code I find it too dangerous, both from a correctness and
performance perspective.
Instead do the change in unix_efile.c, which is considerably
simpler.

and a concurrent exit signal.
We now actually guarantee that the process will not die
from exit signal *after* the call to process_flag(trap_exit,true)
has returned.
The race is narrow and probably quite hard to observe even if you
manage to provoke it. Has only been confirmed with the help of
return trace and a sleep in send_exit_signal().
Solution:
Seize status lock to prevent send_exit_signal() from reading
an old status (without TRAP_EXIT) and then writing PENDING_EXIT
after TRAP_EXIT has been set by process_flag_2().

Those clause are obsolete and never used by common_test.

We don't want otp_internal to only grow, and grow, and grow...

The mentioned functions in erl_internal and erl_eval was removed
a long time ago.

code:set_path/1 no longer returns {error,bad_path} (an exception
will be thrown instead).

reltool_server_SUITE: Correct diffing of start scripts
|
|
In c3c6182, systools was updated to add more modules to be pre-loaded
along with error_handler. That is a pure optimization.
Because of the extra modules, test cases that compared the start
scripts generated by SASL with the ones generated by Reltool
would fail.
We must implement a more elaborate way to diff the scripts.

|
62473daf introduced an unsafe optimization in the loader.
See the comments in the test case for an explanation of
the problem.
