2018-10-26erts: Join empty base nodes in catreeSverker Eriksson
The original implementation did not do this due to fear of bad performance. But we think the negative effect of "leaking" empty base nodes is more important to fix. To get the bad performance a special kind of access patterns is needed where base nodes are frequently emptied and then repopulated soon again. ets_SUITE:throughput_benchmark for example did not show any negative effect from this commit at all.

2018-10-23erts: Refactor DbUpdateHandle with nicer typesSverker Eriksson
2018-10-23erts: Refactor away function generating macros in erl_db_catree.cSverker Eriksson
Easier to read and debug, and about the same lines of code.
2018-10-23erts: Fix faulty assert in catree_find_nextprev_rootSverker Eriksson
It's possible to first find an empty base node and then retry and find the same base node as invalid. It's a benign race with join which first makes the old invalid 'neighbor' accessible from 'gparent' before replacing it with 'new_neighbor'.

2018-10-23erts: Do contention adaptions during (updating) iterationsSverker Eriksson
Once an iteration key has been found, never fall back to first/last key in next/prev tree as trees may split or join under our feet. I.e we must always use previous key when searching for the next key.

2018-10-19erts: Remove tree merging for ets:slotSverker Eriksson
Brute force solution will always iterate tree from slot 0 and forward. ToDo1: Yield. ToDo2: Maybe optimize by caching AVL tree size in each base node.

2018-10-08ssl: ERL-738 - Correct alert handling with new TLS sender processIngela Anderton Andin
With the new TLS sender process, solving ERL-622, TLS ALERTs sent in the connection state must be encrypted and sent by the TLS sender process. This to make sure that the correct encryption state is used to encode the ALERTS. Care must also be taken to ensure a graceful close down behavior both for normal shutdown and downgrading from TLS to TCP. The original TR ERL-738 is verified by cowboy tests, and close down behavior by our tests. However we alas have not been able to yet create a minimal test case for the originating problem. Also it seems it has become less likely that we run in to the TCP delivery problem, that is the guarantee is only on transport level, not application level. Keep work around function in ssl_test_lib but we can have better test as long as we do not get to much wobbling tests.

Fixes a crash during code generation of the following code: call_atom() -> fun({send = Send}) -> Send() end.
2018-10-05compiler: Forward +source flag to epp and fix bug in +deterministicJohn Högberg
The source file path as given to `erlc` was included in an implicit file attribute inserted by epp, even when the +source flag was set to something else which was a bit surprising. It was also included when +deterministic was specified, breaking the flag's promise. This commit forwards the +source flag to epp so it inserts the right information, and if +deterministic is given it will be shaved to just the base name of the file, guaranteeing the same result regardless of how the input is reached.

Note that this does *not* affect -include()'d files or the -file() directive.
