feat: implement native os module

[xhyrom]

Warning
In huge WIP

Note
Implemented, our first PR (@Fire-The-Fox, @xhyrom)

• tests
• bun-types
• faster than other runtimes
• benchmarks
  • cpus()
  • networkInterfaces()
  • arch()
  • endianness()
  • freemem()
  • getPriority()
  • homedir()
  • hostname()
  • loadavg()
  • platform()
  • release()
  • setPriority()
  • tmpdir()
  • totalmem()
  • type()
  • uptime()
  • userInfo()
  • version()

Required before ready to review:

• Install MacOS on VMWare (in progress, my net is slow)
• Make support for MacOS
  • cpus()
  • freemem()
  • loadavg()
  • networkInterfaces()
  • uptime()
  • version()
  • release()
• Test every function
  • linux
  • darwin

import os from "node:os";

for (const p of Object.getOwnPropertyNames(os)) {
    if (p === "setPriority" || p === "default") continue;

    if (typeof os[p] === 'function') console.log(p, os[p]());
    else console.log(p, os[p]);
}

console.log(`priority ${os.getPriority()} (should be 0)`);
os.setPriority(0, 2);
console.log(`priority ${os.getPriority()} (should be 2)`);
os.setPriority(4);
console.log(`priority ${os.getPriority()} (should be 4)`);

Must be implemented:

• os.EOL
• os.arch()
• os.cpus()
• os.devNull
• os.endianness()
• os.freemem()
• os.getPriority() - missing info field in error
• os.homedir()
• os.hostname()
• os.loadavg()
• os.networkInterfaces()
• os.platform()
• os.release()
• os.setPriority() - missing info field in error
• os.tmpdir()
• os.totalmem()
• os.type()
• os.uptime()
• os.userInfo() - missing encoding option
• os.version()
• os.constants
  • os.constants.signals
  • os.constants.errno
  • os.constants.dlopen
  • os.constants.priority
  • UV_UDP_REUSEADDR

// RUN WITH NODEJS NO BUN
const os = require("node:os");

let declarations = "";
let addToModule = "";
for (const [key, value] of Object.entries(os.constants.signals)) {
    declarations += `   pub const ${key} = ${value};\n`;
    addToModule += `    constantsModule.put(globalObject, &JSC.ZigString.init("${key}"), JSC.JSValue.jsNumber(${key}));\n`
}

console.log([
    declarations,
    '',
    'pub fn create(module: JSC.JSValue, globalObject: *JSC.JSGlobalObject) callconv(.C) void {',
    `   const constantsModule = JSC.JSValue.createEmptyObject(globalObject, ${Object.keys(os.constants.signals).length});`,
    `   ${addToModule}`,
    '   module.put(globalObject, &JSC.ZigString.init("dlopen"), constantsModule);',
    '}',
].join('\n'));

Big ❤️ for @Fire-The-Fox . He help me with cpus and networkInterfaces

Thank you for this

Sorry that the patterns in to copy from in the code are unclear. The newer way of writing bindings like this -- using JSC.NewFunction() should be simpler and a little faster at runtime

[Jarred-Sumner]

There's a new and better way to expose ESM modules, but most of the code hasn't been migrated to it. Have a look at ProcessModule.h.

Instead of adding a new property and writing JS wrapper code, we can directly expose the JSValue objects

[Jarred-Sumner]

We can delete this file if we use the same way as ProcessModule.h

not finished corrupted double-linked list

@Jarred-Sumner everything works, tested:

import os from "node:os";

for (const p of Object.getOwnPropertyNames(os)) {
    if (p === "setPriority" || p === "default") continue;

    if (typeof os[p] === 'function') console.log(p, os[p]());
    else console.log(p, os[p]);
}

console.log(`priority ${os.getPriority()} (should be 0)`);
os.setPriority(0, 2);
console.log(`priority ${os.getPriority()} (should be 2)`);
os.setPriority(4);
console.log(`priority ${os.getPriority()} (should be 4)`);

console.log('STARTING 100 TIMES - CP');
for (let i = 0; i < 100; i++) {
    os.cpus();
}

console.log('STARTING 100 TIMES - NT');
for (let i = 0; i < 100; i++) {
    os.networkInterfaces();
}

but you should test it on darwin :D - we cant, because VM

awesome work @xhyrom @Fire-The-Fox
