Code such as that the following:
Val = map_get(a, Map),
Map#{a:=z} %Could be any map update
would incorrectly cause an internal consistency check failure:
Internal consistency check failed - please report this bug.
Instruction: {put_map_exact,{f,0},{x,0},{x,0},1,{list,[{atom,a},{atom,z}]}}
Error: {bad_type,{needed,map},{actual,term}}:
Update beam_validator so that it understands that the second
argument for map_get/2 is a map.

beam_type assumed that the operand for the bs_context_to_binary
instruction must be a binary. That is not correct;
bs_context_to_binary accepts anything. Based on the incorrect
assumption, beam_type would remove other test instructions.
The bug was introduced in eee8655788d2, which was supposed
to be just a refactoring commit.

The compiler would crash when compiling code such as:
serialize(#{tag := value, id := Id, domain := Domain}) ->
[case Id of
nil ->
error(id({required, id}));
_ ->
<<10, 1:16/signed, Id:16/signed>>
end,
case Domain of
nil ->
error(id({required, domain}));
_ ->
<<8, 2:16/signed, Domain:32/signed>>
end].
The crash would look like this:
Function: serialize/1
t.erl: internal error in block2;
crash reason: {badmatch,false}
in function beam_utils:live_opt/4 (beam_utils.erl, line 861)
in call from beam_utils:live_opt/1 (beam_utils.erl, line 285)
in call from beam_block:function/2 (beam_block.erl, line 47)
in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33)
in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33)
in call from beam_block:module/2 (beam_block.erl, line 33)
in call from compile:block2/2 (compile.erl, line 1358)
in call from compile:'-internal_comp/5-anonymous-1-'/3 (compile.erl, line 349)
The reason for the crash is an assertion failure caused by a previous
unsafe optimization. Here is the code before the unsafe optimization:
.
.
.
{bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}.
{bs_put_string,3,{string,[8,0,2]}}.
{bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}.
{move,{x,1},{x,0}}.
{test_heap,4,1}.
.
.
.
beam_block:move_allocate/1 moved up the test_heap/2 instruction past the
move/2 instruction, adjusting the number of live registers at the same
time:
.
.
.
{bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}.
%% Only x1 is live now.
{bs_put_string,3,{string,[8,0,2]}}.
{bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}.
{test_heap,4,2}. %Unsafe. x0 is dead.
{move,{x,1},{x,0}}.
.
.
.
This optimization is unsafe because the bs_init2 instruction killed
x0.
The bug is in beam_utils:anno_defs/1, which adds annotations indicating
the registers that are defined at the beginning of each block. The
annotation before the move/2 instruction incorrectly indicated that
x0 was live.

Included config files relative to sys.config directory
OTP-15137
|
|
Change the way included config files are searched in sys.config.
Search first relative to sys.config directory, then relative
to current working directory, for backward compatibility.
This permit same result when using a sys.config file in a release
or starting manually a node with -config.

According to valgrind, there is a memory leak. When fixing that there is a core-dump instead.
Since generate_key is the part that is important for the quality of the key we keep the old
compute_key part to avoid memory leakage.

|
Re-structure dh_compute_key_nif and dh_generate_key_nif to see variable scoping and alloc/dealloc pairs better
