uvicorn vs #rust 的单/多线程跑分: 差异 10%

from blacksheep import Application
import asyncio
app = Application()
@app.route("/async")
async def test_async():
    await asyncio.sleep(.002)
    return "OK"

import logging; 对象支持 Formatter('%(name).%(asctime)s: %(message)s'), RotatingFileHandler('my_log.log', maxBytes=2000, backupCount=10) 的参数配置, 默认print WARN以上的记录, logger.exception() 默认 ERROR

#fuck u cffi, what <cdata>? Is strconv&cdef(errItem=ignore) that hard?

我之前有个dl-preload+ptrace nmhook库，本来可以学 frida.re py魔改二进制的，看来FFI界的烂API又要麻烦我了 😅
Frida is Greasemonkey for native apps

? import frida-tools
sudo frida-trace -i "readdir"  telegram-desktop
#ffi.offsetof('struct dirent*','d_name')
log(args[0],Memory.readCString(args[0].add(19)));

变颜色说明参数变了，也只有这些信息量
后来结合 r2 -d $(pidof telegram-desktop); 每次选文件时Ctrl+C再 dc; V
发现 arg0 处啥都没，但后面是dirent* 的游标
查了一下才知道要通过fd读取，不过好像不是tg在读文件夹……

log(Memory.readU32(args[0]));

readlink /proc/$(pidof telegram-desktop)/fd/*

完全看不到在选的位置

#reveng 只是持久化还是要依靠 Xposed

Java.perform(function() {
    var Button = Java.use("android.widget.Button");

    Button.setOnClickListener.implementation = function(listener) {
        listener.onClick.implementation=()=>console.log("Button onClick stopped");

        // Call the original onClick method
        return this.setOnClickListener(listener);
    };
});

btw. 这个作者还用FastAPI暴露函数参数…… 说明 Frida.re 完全是不支持跨语言和ffi的
