erts: Fix integer overflow in loader
erts: Fix integer overflow in list subtraction
|
|
qsort expects the comparison function to return an int; returning
an `Sint` may yield nonsensical results.
|
|
CMP_TERM returned an `Sint`, which overflowed the `int` used in
erl_rbtree for storing the comparison, causing list subtraction to
behave strangely.

Add a simple test case that tests that its possible to

An invalid value test caused the

The following sequence would be wrongly optimized into a
i_get_tuple_element2 instruction, reading an element from the
wrong tuple:
{get_tuple_element,{x,0},1,{x,0}}.
{get_tuple_element,{x,0},2,{x,1}}.

This reverts commit 70dbf671a8196110d2aee2e7507afc2c2c75183f.
As the comment of 70dbf671a8 itself indicates, that "fix" is not really
necessary. It has, however, the bad effect of always consuming reductions of the
process you want to know reduction from, that is you can't meassure reduction
count without affecting it.

* bjorn/erts/fix-wrong-class/ERIERL-367/OTP-15834:
Fix sticky class in exception
|
|
When catching an exception re-throwing with a changed
class, the class could be changed to the original class
if the exception got caught and rethrown in (for example)
an after block:
sticky_class() ->
try
try
throw(reason)
catch
throw:Reason:Stack ->
erlang:raise(error, Reason, Stack)
end
after
ok
end.

After calculating the length of a list, length/1 would accidentally
bump all remaining reductions, forcing the process to yield. Correct
the calculation.

Not 100% sure this is needed to get correct reductions
as the direct query is not done if process is RUNNING anyway.

erts: Add documentation for distribution fragments

* lukas/OTP-22/misc-fixes/OTP-15791:
erts: Fix so that non-oneshot pollset on OpenBSD works
erts: Remove dead cpu info code in erlexec
erts: Remove -instr from erlexec flags
|
|
The poll code for kevent on OpenBSD and NetBSD had not been fixed
to work properly when disabling events in the scheduler poll-set.
Because they use ONESHOT the delete operation was built into the
trigger and thus a lot of code was not needed when doing oneshot,
however it is needed when doing non-oneshot.

* john/erts/alloc-header-packing-win64:
erts_alloc: Fix header packing on Win64
|
|
When a fragmented down/exit is sent to a non-existing process the message
would just be dropped without being deallocated.
|
|
Symptom:
Failed debug assert in find_next_timeout
ERTS_TW_ASSERT(tiw->yield_slot == ERTS_TW_SLOT_INACTIVE);
Problem:
If remove_timer() was called in between yielding erts_bump_timers()
tiw->true_next_timeout_time could be set to 0 leading to
find_next_timeout() being called before all bumping is done.
Solution:
Don't clear tiw->true_next_timeout_time in remove_timer()
if tiw->yield_slot is active.
Does not seem this bug could cause other more harmful symptoms,
but not sure.
