blink VS strace

> Consider offering APE for x64 but then still producing ARM binaries the old fashioned way.

The recent version of cosmopolitan generates ARM binaries for Linux and MacOS (https://github.com/jart/cosmopolitan#arm; mode aarch64). There is also blink that provides the x86-64 emulation layer for (APE and other) binaries on a variety of platforms (https://github.com/jart/blink).

Would love a second pair of eyes on the powerpc64le JIT, since it partially works but hangs on some tests. https://github.com/jart/blink/issues/17

I've never used it, but https://github.com/jart/blink is pretty much that. It's tiny and:

> We regularly test that Blink is able run x86-64-linux binaries on the following platforms:

> Linux (x86, ARM, RISC-V, MIPS, PowerPC, s390x)

> macOS (x86, ARM)

> FreeBSD

> OpenBSD

> Cygwin

I wonder if blink could be used as a lightweight sandbox. Looking at PR46[0], it seems sandboxing is not one of the current features, but it would be cool to have a way to run arbitrary code (e.g: Python) in a sandboxed environment. Even cooler if you could limit the amount of memory/CPU used.

There's a pretty decent set of autogenerated lists present in strace source, see e.g. https://github.com/strace/strace/blob/master/src/linux/64/io...

I guess the only way to find out is to make use of the fact that strace is OSS. https://github.com/strace/strace As I mentioned this is outside my skill level, but looking at the top level files I can see many references to output buffering so you may well be SOL.

No no noooo. Nope. Not even close. There's mountains of work down here. It's just less sexy, and less visible. There are a surprising number of ubiquitous sysutils that have very few relative github stars or whatever. Look at https://github.com/strace/strace for example. Laughably few stars compared to the flavor of the month javascript framework -- but does that mean that I can't find it on all of our *nix machines? Nope, it's on basically all of them.

Maybe taking a look at the strace source repository can help you along.

Program(Process) Tracing (ptrace) Tools: Establishes tracing operation during the execution of the application. Contains the traces of the index of instructions executed and the data referenced during execution. These are greatly used by developers for debugging purposes. Some examples of ptrace tools are, Strace, Ltrace, Opensnoop, and Valgrind Lackey.
