2018-10-29Optimize operator '--' and yield on large inputsJohn Högberg
The removal set now uses a red-black tree instead of an array on large inputs, decreasing runtime complexity from `n*n` to `n*log(n)`. It will also exit early when there are no more items left in the removal set, drastically improving performance and memory use when the items to be removed are present near the head of the list. This got a lot more complicated than before as the overhead of always using a red-black tree was unacceptable when either of the inputs were small, but this compromise has okay-to-decent performance regardless of input size.

2018-10-26Inline erts_cmpJohn Högberg
This greatly increases the performance of '--'/2 which does a lot of term comparisons.

2018-10-25Fix trapping in lists:reverse/2John Högberg
The first stage wasn't bounded by reductions, and it bumped far more reductions than it should have due to a logic bug.

2018-10-19ssl: Refactor AEAD ciphersIngela Anderton Andin
TLS-1.3 needs to handle AEAD inputs diffrently than previous versions. Refactor code to facilitate TLS-1.3 additions. Change CHACHA20_POLY1305 NONCE to match RFC 7905. This will be important later when we fix interop with TLS compatible crypto invocation.

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).
