Add HTTP/HTTPS Fetch() API to redbean You can now say the following in your redbean Lua code: status,headers,payload = Fetch("https://foo.example") The following Lua APIs have been introduced: - Fetch(str) → str,{str:str},str - GetHttpReason(int) → str - GetHttpReason(int) → str - ProgramSslFetchVerify(bool) - ProgramSslClientVerify(bool) The following flags have been introduced: - `-j` enables client SSL verification - `-k` disables Fetch() SSL verification - `-t INT` may now be passed a negative value for keepalive Lua exceptions now invoke Cosmopolitan's garbage collector when unwinding the stack. So it's now safe to use _gc() w/ Lua 𝔱𝔥𝔯𝔬𝔴 See #97

Make SSL handshakes much faster This change boosts SSL handshake performance from 2,627 to ~10,000 per second which is the same level of performance as NGINX at establishing secure connections. That's impressive if we consider that redbean is a forking frontend application server. This was accomplished by: 1. Enabling either SSL session caching or SSL tickets. We choose to use tickets since they reduce network round trips too and that's a more important metric than wrk'ing localhost. 2. Fixing mbedtls_mpi_sub_abs() which is the most frequently called function. It's called about 12,000 times during an SSL handshake since it's the basis of most arithmetic operations like addition and for some strange reason it was designed to make two needless copies in addition to calling malloc and free. That's now fixed. 3. Improving TLS output buffering during the SSL handshake only, so that only a single is write and read system call is needed until blocking on the ping pong. redbean will now do a better job wiping sensitive memory from a child process as soon as it's not needed. The nice thing about fork is it's much faster than reverse proxying so the goal is to use the different address spaces along with setuid() to minimize the risk that a server key will be compromised in the event that application code is hacked.
