Sometimes processes have not had the time to spread
from one scheduler. Force spread by using the undocumented
'scheduler' option.

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.

seen to cause redundant {profile,_,active,_,_} messages
when process is terminating.

Symptom: Heap corruption
Expanded test case to provoke this bug
and test some more term types.

* lukas/erts/dirty_trace_clean_fix/OTP-14938:
erts: Delay cleanup of removed tracer on dirty scheds
|
|
It is not simple to do the correct de-allocation on
a dirty schedulers, so we just delay it until this
process runs on a normal scheduler.
|
|
|
|
|

|
by testing F_SENSITIVE only once.
|
|
Exclude garbing processes, EXCEPT if run by crash dumping thread
in which case we assume the heap is healthy
without any move markers yet/left.
Switched order between (allocating) setup_rootset()
and (move marking) collect_live_heap_frags().

When supplied without an enclosing list, bitstrings were returned
as-is instead of badarging.
|
|
|
|
A binary is a binary as long as its size in bits is evenly divisible
by 8, regardless of whether it has a bit offset or not.
|
|
When supplied without an enclosing list, bitstrings were silently
truncated to [] instead of badarging.
|
|
This has always worked but we lacked test coverage for it.
|
|
Huge inputs weren't particularly useful and took forever to run, so
this commit winds it down to a more sane level that still causes
lots of yielding.

Fix rounding bug in float_to_list/2
|
|
particularly slow erlc when compiler is hipe compiled.
hipe_unified_loader:load did not patch external call sites
and instead caused a double hipe mode switch per call.
hipe_unified_loader:load is only used
for early modules first loaded as beam
and by code:atomic_load and friends.

Replace long long with Uint64

Example symptom:
1> float_to_list(0.145, [{decimals,1}]).
"0.2"
There were two problems in sys_double_to_chars_fast
1. Most serious was adding 0.55555555 / (10^D) instead of 0.5 / (10^D)
which imposed a 5.5% risk of a faulty rounding up.
2. Using fixpoint for frac_part which lost significant bits if F < 0.5

Before:
1> binary_to_integer(<<":">>, 16).
3
After:
1> binary_to_integer(<<":">>, 16).
** exception error: bad argument
in function binary_to_integer/2
called as binary_to_integer(<<":">>,16)
Prior to this change, both list_to_integer/2 and binary_to_integer/2
would convert strings with values between ASCII '9' up to '0'+base for
base > 10. For example, when converting in base 16, you could pass ':',
';', '<', '=', '>', and '?' without getting an exception. This was due
to a missing check in c2int_is_invalid_char().
This change adds the missing check and a regression test for passing
':'. It also simplifies the code and tightens up an out-of-bounds check
to make it off-by-one rather than off-by-two.

Fix GC bug for HiPE primop bs_put_utf8
|
|
in order to detect incompatible changes in primop interface
(which we just did for bs_put_utf8) and refuse hipe loading.
|
|
by preventing it from doing GC, which generated code relies on.
