Remove unsafe optimization for delaying creation of stackframe
|
|
New internal active N changed timing, and
new check is needed.
|
|
The charset detection parsing crash in some cases when
the XML directive is not syntactic correct.

b89044a800c4 introduced an optimization that tries to delay creation
of stack frames. It turns out that this optimization is not always
safe. (See the new test case for an example.)
Since the code generator is completely rewritten in the `master`
branch for the upcoming OTP 22 release, it does not make sense trying
to mend this optimization. It is better to remove it. Out of a sample
of about 1000 modules in OTP, about 50 of them are changed as a result
of removing this optimization.
The compiler in OTP 22 will do the same optimization in a cleaner,
safer, and more effective way.

Wtite connection state was not synchronized when peer initiated renegotiation
|
|
|
|
As the stop wrapper functions are no longer needed after tls_sender
that altered the behaviour of the TLS distribution code.
|
|
Both test case and code needed updates to work as intended. Code needed update due to
new tls_sender process and the test case gave false positive reusult erarlier probably
due to beeing to sloopy in order to avoid timeouts.

Similar bug as for bxor fixed by abc4fd372d476821448dfb9
Ex:
1> io:format("~.16B\n", [-16#1110000000000000000 band (-1)]).
-1120000000000000000
Wrong result for
(-X bsl WS) band -Y.
where
X is any positive integer
WS is erlang:system_info(wordsize)*8*N where N is 1 or larger
Y is any positive integer smaller than (1 bsl WS)
Fix:
The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.

Due to comparison as a signed integer, when getting an unsigned atomic
in the range 2^63-1..2^64-1 (when the most significant bit was set), the
heap could get corrupted when the integer was retrieved: hsz would get
set to zero, but the code proceeded to build a bignum.
Steps to reproduce (at least on x86_64):
$ erl
1> A = atomics:new(1,[{signed,false}]).
2> atomics:put(A,1,18446744073709551615).
3> atomics:get(A,1).
At the last step, the shell would print some garbage and hang.

At start of the VM a poll-set that the schedulers
will check is created where fds that have triggered
many (at the moment, many means 10) times without
being deselected inbetween. In this scheduler specific
poll-set fds do not use ONESHOT, which means that the
number of syscalls goes down dramatically for such fds.
This pollset is introduced in order to handle fds that
are used by the erlang distribution and that never
change their state from {active, true}.
This pollset only handles ready_input events,
ready_output is still handled by the poll threads.
During overload, polling the scheduler poll-set is done
on a 10ms timer.

Fix unsafe optimization of stack trace building
|
|
|
|
|
|
The `sys_core_fold` pass of the compiler would optimize
away the building of the stacktrace in code such as:
try
...
catch
C:R:Stk ->
erlang:raise(C, {R,Stk}, Stk)
end
That optimization is unsafe and would cause a crash in a later compiler
pass.
