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 chibicc This program popped up on Hacker News recently. It's the only modern compiler I've ever seen that doesn't have dependencies and is easily modified. So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries.

Pay off more technical debt This makes breaking changes to add underscores to many non-standard function names provided by the c library. MODE=tiny is now tinier and we now use smaller locks that are better for tiny apps in this mode. Some headers have been renamed to be in the same folder as the build package, so it'll be easier to know which build dependency is needed. Certain old misguided interfaces have been removed. Intel intrinsics headers are now listed in libc/isystem (but not in the amalgamation) to help further improve open source compatibility. Header complexity has also been reduced. Lastly, more shell scripts are now available.

Make major improvements to redbean and libraries The most exciting improvement is dynamic pages will soon be able to use the executable itself as an object store. it required a heroic technique for overcoming ETXTBSY restrictions which lets us open the executable in read/write mode, which means (1) wa can restore the APE header, and (2) we can potentially containerize redbean extension code so that modules you download for your redbean online will only impact your redbean. Here's a list of breaking changes to redbean: - Remove /tool/net/ prefix from magic ZIP paths - GetHeader() now returns NIL if header is absent Here's a list of fixes and enhancements to redbean: - Support 64-bit ZIP archives - Record User-Agent header in logs - Add twelve error handlers to accept() - Display octal st_mode on listing page - Show ZIP file comments on listing page - Restore APE MZ header on redbean startup - Track request count on redbean index page - Report server uptime on redbean index page - Don't bind server socket using SO_REUSEPORT - Fix #151 where Lua LoadAsset() could free twice - Report rusage accounting when workers exit w/ -vv - Use ZIP iattr field as text/plain vs. binary hint - Add ParseUrl() API for parsing things like a.href - Add ParseParams() API for parsing HTTP POST bodies - Add IsAcceptablePath() API for checking dots, etc. - Add IsValidHttpToken() API for validating sane ASCII - Add IsAcceptableHostPort() for validating HOST[:PORT] - Send 400 response to HTTP/1.1 requests without a Host - Send 403 response if ZIP or file isn't other readable - Add virtual hosting that tries prepending Host to path - Route requests based on Host in Request-URI if present - Host routing will attempt to remove or add the www. prefix - Sign-extend UNIX timestamps and don't adjust FileTime zone Here's some of the improvements made to Cosmopolitan Libc: - Fix ape.S indentation - Improve consts.sh magnums - Write pretty good URL parser - Improve rusage accounting apis - Bring mremap() closer to working - Added ZIP APIs which will change - Check for overflow in reallocarray() - Remove overly fancy linkage in strerror() - Fix GDB attach on crash w/ OpenBSD msyscall() - Make sigqueue() portable to most UNIX distros - Make integer serialization macros more elegant - Bring back 34x tprecode8to16() performance boost - Make malloc() more resilient to absurdly large sizes

Import C++ Standard Template Library You can now use the hardest fastest and most dangerous language there is with Cosmopolitan. So far about 75% of LLVM libcxx has been added. A few breaking changes needed to be made to help this go smoothly. - Rename nothrow to dontthrow - Rename nodiscard to dontdiscard - Add some libm functions, e.g. lgamma, nan, etc. - Change intmax_t from int128 to int64 like everything else - Introduce %jjd formatting directive for int128_t - Introduce strtoi128(), strtou128(), etc. - Rename bsrmax() to bsr128() Some of the templates that should be working currently are std::vector, std::string, std::map, std::set, std::deque, etc.

Make terminal ui binaries work well everywhere Here's some screenshots of an emulator tui program that was compiled on Linux, then scp'd it to Windows, Mac, and FreeBSD. https://justine.storage.googleapis.com/blinkenlights-cmdexe.png https://justine.storage.googleapis.com/blinkenlights-imac.png https://justine.storage.googleapis.com/blinkenlights-freebsd.png https://justine.storage.googleapis.com/blinkenlights-lisp.png How is this even possible that we have a nontrivial ui binary that just works on Mac, Windows, Linux, and BSD? Surely a first ever achievement. Fixed many bugs. Bootstrapped John McCarthy's metacircular evaluator on bare metal in half the size of Altair BASIC (about 2.5kb) and ran it in emulator for fun and profit.

Update curl example to support ssl / https Now that we know our SSL client works, and that it's able to verify certificates, the next step will be adding it as an API to redbean. See #97

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
