2018-10-24Merge pull request #1991 from bjorng/bjorn/erts/fix-max_heap_size/OTP-15360Björn Gustavsson
Honor the max heap size when copying literals after purging
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: Fix slot bug in find_next/prevSverker Eriksson
2018-10-23erts: Fix lc_key in base nodesSverker Eriksson
to actually pass the copy to lock checker.
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.

to not have to backtrack up on the stack.
2018-10-23erts: Add erts_debug feature 'ets_force_split'Sverker Eriksson
to easier generate a routing tree for test without having to spend cpu to provoke actual repeated lock conflicts.

2018-10-19erts: Remove tree merging for print and foreach_offheapSverker Eriksson
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.

2018-10-19erts: Add table type assertions for static stack accessSverker Eriksson
DbTableCATree has no static stack.

2018-10-19Fix hanging gen_tcp send vs close raceRaimo Niskanen
While a gen_tcp send was in progress with filled buffers and slow receiver a close (from another process) would place the port in a half dead state so the port could not signal back to send, that waited for confirmation. The solution is to after some time (5 s) of waiting for send confirmation set a monitor on the port, which detects if the port becomes half dead due to close from another process. The close pending loop has also been improved to use the linger timeout for waiting, and to set a system timeout (arbitrarily selected 3 min) to not wait forever when the other end reads data s l o w l y (tarpitting, kind of).
2018-10-19Honor the max heap size when copying literals after purgingBjörn Gustavsson
When a module has been purged from memory, any literals belonging to that module will be copied to all processes that hold references to them. The max heap size limit would be ignored in the garbage collection initiated when copying literals to a process. If the max heap size was exceeded, the process would typically be terminated in the following garbage collection. Since the process would be killed anyway later, kill the process before copying a literal that would make it exceed its max heap size. While at it, also fix a potential bug in `erlang:garbage_collect/0`. If it was found that the max heap sized had been exceeded while executing `erlang:garbage_collect/0`, the process would enter a kind of zombie state instead of being properly terminated.
