2018-06-04erts: Increase scalability of ets name lookupSverker Eriksson
by expanding the default size of the hash table and increase number of locks.

* lukas/erts/fix-scheduler-data-sched-out-bug/OTP-13123: erts: Make sure scheduler_data is set
2018-05-25erts: Make sure scheduler_data is setLukas Larsson
If scheduler_data is not set correctly on normal schedulers the code in erts_schedule_time_break and possibly others will trigger asserts.

2018-05-22erts: Let allocator pooled_tree also use Age OrderSverker Eriksson
if configured for the allocator. This was not implemented and pooled_tree always used address order first fit. The "problem" was as a carrier can be part of both the pooled tree (of its owner) and the allocation tree (of a foreign instance) at the same time. Solved by duplicating 'birth_time' in both AOFF_RBTree_t nodes for each carrier. Blocks still cannot use age order and does not pay any memory cost for birth_time.

2018-05-18erts: Fix narrow race between ets:new and ets:deleteSverker Eriksson
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
2018-05-16epmd: allow alternative to dns resolving for nodenameTimmo Verlaan
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.

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

from ensure_dirty_proc_handled as an outline function callable from inline functions.
2018-05-15Do not hold runq lock while deleting a processRickard Green
2018-05-15erts: Make cpu_timestamp use per thread on LinuxLukas Larsson
If we don't use per thread the value becomes completely nonsensical on systems with more than one scheduler. We keep the old solaris behaviour in order to support the option, but it only really works when using a single scheduler.
2018-05-15erts: Fix unused variable warning in unix prim fileLukas Larsson
2018-05-15erts: Fix erts_os_times warningLukas Larsson
2018-05-09erts: Try fix contant maps:next orderSverker Eriksson
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.
2018-05-09Disable the use of floating point exceptionsBjörn Gustavsson
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.) https://bugs.erlang.org/browse/ERL-620
2018-05-08erts: Rename untrapping db_free_*empty*_tableSverker Eriksson
as it's now only used for empty tables by ets:new/2.
2018-05-08erts: Make ets:delete_all_objects yield on fixed tableSverker Eriksson
2018-05-08erts: Optimize ets delete all in fixed tableSverker Eriksson
by only allocating one FixedDeletion with the new "all" flag instead of one FixedDeletion per slot.
2018-05-08erts: Refactor ets select iteration codeSverker Eriksson
* Remove all "mtraversal_" prefixes. * Rename all local context variables as "ctx". * Changed callbacks from function arguments to members of new base context struct "match_callbacks_t" * Remove unnecessary struct initializations "= {0}"
2018-05-08erts: Cleanup ets codeSverker Eriksson
2018-05-08erts: Optimize ets hash object deallocactionsSverker Eriksson
to be done after lock has been released.
2018-05-08erts: Refactor pseudo deleted ets objectsSverker Eriksson
Separate pseudo-deleted-flag from the hash value.
2018-05-08erts: Make atomic ets:delete_all_objects yieldSverker Eriksson
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.
