* maint: ops.tab: Fix potentially unsafe optimization of raise/2
2018-09-03ops.tab: Fix potentially unsafe optimization of raise/2Björn Gustavsson
The operands for the raise/2 instruction are almost always in x(2) and x(1). Therefore the loader translates the raise/2 instruction to an i_raise/0 instruction which uses the values in x(2) and x(1). If the operands happens to be in other registers, the loader inserts move/2 instruction to move them to x(2) and x(1). The problem is that x(3) is used as a temporary register when generating the move/2 instructions. That is unsafe if the Value operand for raise/2 is x(3). Thus: raise x(0) x(3) will be translated to: move x(0) x(3) move x(3) x(1) move x(3) x(2) i_raise The Trace will be written to both x(2) and x(1). The current compiler will never use x(3) for the Value operand, so there is no need to patch previous releases. But a future compiler version might allocate registers differently.

2018-08-28dialyzer: Improve handling of complex guardsHans Bolinder
See also https://bugs.erlang.org/browse/ERL-680. The right associative short circuit expressions 'andalso' and 'orelse' are expanded by the Compiler (see v3_core) into 'case' expressions. If parentheses are used to enforce left associativeness, variables are introduced, and the time needed by Dialyzer increases exponentially. Rather than trying to fix Dialyzer itself, v3_core now rewrites repeated use of 'andalso' ('orelse') into right associative expressions before creating the 'case' expressions.

2018-08-27ssl: Improve close handlingIngela Anderton Andin
We want to make sure that the sender process that may get stuck in prim_inet:send will die if the tls_connection process is terminated. And we also like to make sure that it terminates as gracefully as possible. So when the tls_connection process dies it spawns a killer process that will brutaly kill the sender if it is unresponsive and does not terminate due to its monitor of the tls_connetion process triggering. When the sender process also acts as distribution controller it may also have other processess that it is linked with that it should bring down or that could bring the connection down.

2018-08-27ssl: Add new sender process for TLS state machineIngela Anderton Andin
Separate sending and receiving when using TCP as transport as prim_inet:send may block which in turn may result in a deadlock between two Erlang processes communicating over TLS, this is especially likely to happen when running Erlang distribution over TLS.

2018-08-24inets: Robust handling of 204, 304, 1xx responsesPéter Dimitrov
All 1xx (informational), 204 (no content), and 304 (not modified) responses MUST NOT include a message-body, and thus are always terminated by the first empty line after the header fields. This implies that chunked encoding MUST NOT be used for these status codes. This commit updates the client to gracefully handle responses from faulty server implementations that can send chunked encoded 204, 304 or 1xx responses.
