Create ELF aliases for identical symbols This change greatly reduces the number of modules that need to be compiled. The only issue right now is that sometimes when viewing symbol table entries, the aliased symbol is chosen.

Add test for ioctl(SIOCGIFCONF) and polyfill on BSDs - Use nullness checks when calling weakly linked functions. - Avoid typedef for reasons described in Linux Kernel style guide. - Avoid enum in in Windows headers. Earlier in Cosmo's history all one hundred files in libc/nt/enum/ used to be enums and it resulted in gigabytes of DWARF data almost as large as everything else in the codebase combined. - Bitfields aren't our friends. They have frequent ABI breakages, inconsistent arithmetic across compilers, and different endianness between cpus. Compiler authors also haven't invested much roi into making bit fields go fast so they produce poor assembly. - Use memccpy() instead of strncpy() or snprintf() for length-bounded copying of C strings. strncpy() is a misunderstood function and snprintf() is awesome but memccpy() deserves more love.

Add SSL to redbean Your redbean can now interoperate with clients that require TLS crypto. This is accomplished using a protocol polyglot that lets us distinguish between HTTP and HTTPS regardless of the port number. Certificates will be generated automatically, if none are supplied by the user. Footprint increases by only a few hundred kb so redbean in MODY=tiny is now 1.0mb - Add lseek() polyfills for ZIP executable - Automatically polyfill /tmp/FOO paths on NT - Fix readdir() / ftw() / nftw() bugs on Windows - Introduce -B flag for slower SSL that's stronger - Remove mbedtls features Cosmopolitan doesn't need - Have base64 decoder support the uri-safe alternative - Remove Truncated HMAC because it's forbidden by the IETF - Add all the mbedtls test suites and make them go 3x faster - Support opendir() / readdir() / closedir() on ZIP executable - Use Everest for ECDHE-ECDSA because it's so good it's so good - Add tinier implementation of sha1 since it's not worth the rom - Add chi-square monte-carlo mean correlation tests for getrandom() - Source entropy on Windows from the proper interface everyone uses We're continuing to outperform NGINX and other servers on raw message throughput. Using SSL means that instead of 1,000,000 qps you can get around 300,000 qps. However redbean isn't as fast as NGINX yet at SSL handshakes, since redbean can do 2,627 per second and NGINX does 4.3k Right now, the SSL UX story works best if you give your redbean a key signing key since that can be easily generated by openssl using a one liner then redbean will do all the things that are impossibly hard to do like signing ecdsa and rsa certificates that'll work in chrome. We should integrate the let's encrypt acme protocol in the future. Live Demo: https://redbean.justine.lol/ Root Cert: https://redbean.justine.lol/redbean1.crt

Introduce --strace flag for system call tracing This is similar to the --ftrace (c function call trace) flag, except it's less noisy since it only logs system calls to stderr. Having this flag is valuable because (1) system call tracing tells us a lot about the behavior of complex programs and (2) it's usually very hard to get system call tracing on various operating systems, e.g. strace, ktrace, dtruss, truss, nttrace, etc. Especially on Apple platforms where even with the special boot trick, debuggers still aren't guaranteed to work. make -j8 o//examples o//examples/hello.com --strace This is enabled by default in MODE=, MODE=opt, and MODE=dbg. In MODE=dbg extra information will be printed. make -j8 MODE=dbg o/dbg/examples o/dbg/examples/hello.com --strace |& less This change also changes: - Rename IsText() → _istext() - Rename IsUtf8() → _isutf8() - Fix madvise() on Windows NT - Fix empty string case of inet_ntop() - vfork() wrapper now saves and restores errno - Update xsigaction() to yoink syscall support

Make improvements - Emulator can now test the αcτµαlly pδrταblε εxεcµταblε bootloader - Whipped up a webserver named redbean. It services 150k requests per second on a single core. Bundling assets inside zip enables extremely fast serving for two reasons. The first is that zip central directory lookups go faster than stat() system calls. The second is that both zip and gzip content-encoding use DEFLATE, therefore, compressed responses can be served via the sendfile() system call which does an in-kernel copy directly from the zip executable structure. Also note that red bean zip executables can be deployed easily to all platforms, since these native executables work on Linux, Mac, BSD, and Windows. - Address sanitizer now works very well
