# SERVASM: Your other webserver. Minimal x86_64 Linux-only file webserver, written in assembly language. It doesn't allocate any memory, using only stack to serve files. *Not intended for production use.* ## How it works: Main process setups listing socket on 8080 port with few system calls: `socket(2)` -> `bind(2)` -> `listen(2)` After main process blocks on on `accept(2)` system call until client connects. Then it `fork(2)` main process passing dealing with request in child process and `accept(2)`'ing again in main. On a child process sets `alarm(2)` to drop very slow clients, and `recv(2)` headers. We do couple checks on incoming request (only GET requests are `supported). open(2)` file and get its size with `fstat(2). write(2)` headers and let the kernel send rest with `sendfile(2)`. After we `close(2)` socket and file. In a case of error we exit process with passing system call result as exit code. ## Running Compiling server requires `nasm` assembler. `make && ./server` ## Debugging `make && strace -v -s 512 -f ./server` ## License Copyright (c) 2015 Vladimir Terekhov Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
