本文介绍了如何在Linux环境下通过root启动VSCode，并配置别名。同时，详细解析了VSCode中文件事件和时间事件的结构，包括aeFileEvent、aeTimeEvent和aeFiredEvent等。此外，还探讨了accept事件处理中的connection、client和aeFileEvent->clientData的关系及其处理流程，包括连接创建、读写事件的处理。

一、root启动vscode:

vim ~/.bashrc

# 添加别名

alias code='code --user-data-dir "~/.vscode-root" --no-sandbox'

source ~/.bashrc

#直接启动

code

settings.json

{
    "files.associations": {
        "cmath": "cpp",
        "type_traits": "cpp",
        "limits": "cpp",
        "typeinfo": "cpp"
    }
}

二、事件处理

/* File event structure */
typedef struct aeFileEvent {
    int mask; /* one of AE_(READABLE|WRITABLE|BARRIER) */
    aeFileProc *rfileProc;
    aeFileProc *wfileProc;
    void *clientData;
} aeFileEvent;

/* Time event structure */
typedef struct aeTimeEvent {
    long long id; /* time event identifier. */
    monotime when;
    aeTimeProc *timeProc;
    aeEventFinalizerProc *finalizerProc;
    void *clientData;
    struct aeTimeEvent *prev;
    struct aeTimeEvent *next;
    int refcount; /* refcount to prevent timer events from being
  		   * freed in recursive time event calls. */
} aeTimeEvent;

/* A fired event */
typedef struct aeFiredEvent {
    int fd;
    int mask;
} aeFiredEvent;

/* State of an event based program */
typedef struct aeEventLoop {
    int maxfd;   /* highest file descriptor currently registered */
    int setsize; /* max number of file descriptors tracked */
    long long timeEventNextId;
    aeFileEvent *events; /* Registered events */
    aeFiredEvent *fired; /* Fired events */
    aeTimeEvent *timeEventHead;
    int stop;
    void *apidata; /* This is used for polling API specific data */
    aeBeforeSleepProc *beforesleep;
    aeBeforeSleepProc *aftersleep;
    int flags;
} aeEventLoop;

2.1 accept事件处理

2.1.1 理清 connection、client、aeFileEvent->clientData之间的关系：

aeFileEvent->clientData = connetction

connection->privateData = client

client->conn = connection

2.1.2 调用堆栈
