These were actually wrong in erl_db.c:

of same named table.
If other process does ets:delete
before ets:new has completely finished and done save_owned_table
then ets:delete might do delete_owned_table and deref wild pointers
in tb->common.owned.

epmd: allow alternative to dns resolving for nodename
|
|
This makes it possible to create a custom integration with a
key-value store for example. The key would then point to the
actual address. You would have to write your own epmd module
to make use of that feature.

Disable the use of floating point exceptions

Fix typos in erl_driver.xml
|
|
|
|
Symptom: maps:iterator+next returns different orders
for the exact same map.
Problem: Number of cached key-values within iterator term
depends on number of input reductions to erts_internal_map_next_3.
Solution: Build cached key-values in destructive non-reverse order
to not affect iteration order.

Floating point exceptions has been disabled since 2011 on macOS
(fa0f8d2c29b) and on Linux since 2014 (c7ddafbe6dbc) because
there were unresolved stability issues.
Floating point exceptions are not disabled by default on FreeBSD,
and if OTP is compiled with gcc (as opposed to clang) floating
point exceptions will be used.
81a6adab693a introduced a bug in erts/emulator/Makefile.in which would
cause the building of OTP to fail if floating point exceptions were
enabled. The bug was not noticed because it turns out that none of our
daily build machines has floating point exceptions enabled.
Since floating point exceptions is not tested, we should not expect
them to work reliably on any platform. Therefore, turn off floating
point exceptions unconditionally in erts/configure.in. For the moment
we will keep the code in the runtime system that handles floating
point exceptions.
(This commit also fixes the bug in erts/emulator/Makefile.in, in
case floating point exceptions ever become reliable and enabled.)

Separate pseudo-deleted-flag from the hash value.

|
by using a cooperative strategy that will make
any process accessing the table execute delelete_all_objects_continue
until the table is empty.
This is not an optimal solution as concurrent threads will still
block on the table lock, but at least thread progress is made.
