Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html

Make improvements - Document redbean's argon2 module - Fix regressions in cthreads library - Make testlib work better with threads - Give the cthreads library lots of love - Remove some of the stdio assembly code - Implement getloadavg() across platforms - Code size optimizations for errnos, etc. - Only check for signals in main thread on Windows - Make errnos for dup2 / dup3 consistent with posix This change also fixes a bug in the argon2 module, where the NUL terminator was being included in the hash encoded ascii string. This shouldn't require any database migrations to folks who found this module and productionized it, since the argon2 library treats it as a c string.

Always initialize thread local storage We had previously not enabled TLS in MODE=tiny in order to keep the smallest example programs (e.g. life.com) just 16kb in size. But it was error prone doing that, so now we just always enable it because this change uses hacks to ensure it won't increase life.com's size. This change also fixes a bug on NetBSD, where signal handlers would break thread local storage if SA_SIGINFO was being used. This looks like it might be a bug in NetBSD, but it's got a simple workaround.

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.

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

The redbean web server receives some minor API additions for controlling things like SSL in addition to filling gaps in the documentation.
