* Remove 'last' arg to sig_enqueue_trace_cleanup
* Only notify 'rp' if enqueue succeeded
|
|
broken on master by
613cde66c25464121f2f6dace99782bad0e07d9b
Scenario:
proc_queue_signal() fails to send switched pending signal
due to state & ERTS_PSFLG_FREE,
and then calls erts_proc_sig_send_monitor_down() to enqueue to self
followed by sig_enqueue_trace_cleanup() that destroyed 'next' pointer
of enqueued signal.
Solution:
Switch order and do sig_enqueue_trace_cleanup() first.

Problem:
1. Process A fixates table T.
2. Process B starts deleting table T (either by ets:delete or exit)
and does tid_clear().
3. Process A exits and does proc_cleanup_fixed_table()
and get NULL from btid2tab() and deallocates DbFixation.
4. Process B continues deleting table in free_fixations_locked()
and finds the deallocated DbFixation in the fixing_procs tree.
Solution:
Wait with tid_clear() until after free_fixations_locked()
has traversed the fixing_procs tree.

We have found cases where compilation drastically slows down
due to this commit. We are working on a minimal cases and plan
to bring this patch back once we can work our the performance
issues.

sys_core_fold could do unsafe transformations on the
code from the old inliner (invoked using the compiler
option `{inline,[{F/A}]}` to request inlining of specific
functions).
To explain the bug, let's first look at an example that
sys_core_fold handles correctly. Consider this code:
'foo'/2 =
fun (Arg1,Arg2) ->
let <B> = Arg2
in let <A,B> = <B,Arg1>
in {A,B}
In this example, the lets can be completely eliminated,
since the arguments for the lets are variables (as opposed
to expressions). Since the variable B is rebound in the
inner let, `sys_core_fold` must take special care when
doing the substitutions.
Here is the correct result:
'foo'/2 =
fun (Arg1, Arg2) ->
{Arg2,Arg1}
Consider a slight modifictation of the example:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg2]
in let <A,B> = <B,[Arg1]>
in {A,B}
Here some of the arguments for the lets are expressions, so
the lets must be kept. sys_core_fold does not handle this
example correctly:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg2]
in let <B> = [Arg1]
in {B,B}
In the inner let, the variable A has been eliminated and
replaced with the variable B in the body (the first B in
the tuple). Since the B in the outer let is never used,
the outer let will be eliminated, giving:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg1]
in {B,B}
To handle this example correctly, sys_core_fold must
rename the variable B in the inner let like this to
avoid capturing B:
'bar'/2 =
fun (Arg1,Arg2) ->
let <B> = [Arg2]
in let <NewName> = [Arg1]
in {B,NewName}
(Note: The `v3_kernel` pass alreday handles those examples correctly
in case `sys_core_fold` has been disabled.)

Add more `compiler_generated` attributes to avoid spurious compiler
warnings triggered by the bug fix in the next commit.
