1.When remote side socket is closed, `SIGPIPE` might be sent. We must ignore and exit correctly (we can't die as we might accept more connections) 2. shutdown and close sockets will inform remote side that socket is closed. Without it, remote side may not notice anything until the next write. GitOrigin-RevId: 51a6204651e49f63ac8b52d9e3e1e4928007c3ff
This project creates three tools: wslproxy (see wslproxy.svg) To avoid connecting from WSL to Windows (such connections may be blocked by firewall) we connect from Windows to WSL instead. This proxy accepts two clients: one for egress (eth0) and one for ingress (loopback). It then passes data between them with two threads. It then reports IP and port via stdout EOF (close stream) written to the stdin kills process. wslhash Calculates hashes and for all files in certain folder to implement custom rsync-like functionality. `rsync` may be missing on some WSL distros, and also it may be slow: access from WSL to Windows takes a lot of time. This tool runs on WSL only, so it is fast. See WslSync.kt It also reports symbolic links ttyfix Sets tty size to workaround https://github.com/microsoft/WSL/issues/10701 To build tool use Makefile. We link it statically because WSL may lack glibc. Kernel ABI is backward compatible, so use some old Linux We use musl libc: https://musl.libc.org/ Not only it produces smaller binaries, but also it is MIT licenced, and we can't link statically with LGPL Get musl automatically: 1. Run "make" (you must have `wget` installed) 2. Open project in CLion if you want Getting musl manually: 1. Download .tar.gz from here: https://musl.libc.org/ 2. unpack to "musl": ``tar xfz musl-1.2.2.tar.gz && mv musl-1.2.2 musl`` 3. run "make" 4. Open project in CLion if you want See https://wiki.musl-libc.org/getting-started.html for more info Q: I got error opening project in CLion: A: Make sure you run "make". Then, tools->Makefile->Reload Q: How do I compile binaries for aarch64 platform? A: Run "make -f Makefile.cross clean all". The required musl cross-compiler will be downloaded and all tools will be cross-compiled for aarch64 platform. Q: How do I check the target platform of the compiled binary? A: Check the output of "file YOUR_BINARY". Q: How do I test that cross-compiled binary works on aarch64? A: Run "sudo apt install qemu-user-static" (adjust for your distro). Then run "qemu-aarch64-static YOUR_BINARY".
