1. 解决PmuOpen之后子进程Execvp获取到的comm和符号数据不匹配的问题 --- ##### 问题: lauch模式需要PmuOpen之后,主进程为main,通知子进程,通过execvp拉起应用falsesharinglong,这种情况下,PmuRead读取到的数据会包含main主进程的数据和falsesharinglong的数据,但是当前的comm只有main,而符号解析的也只有main二进制的符号,无法匹配上falsesharinglong的符号和comm ##### 原因: PmuOpen阶段收集到的进程信息和符号信息无法匹配后面拉起应用采集到的数据 ##### 方法: 通过dummy event监测comm事件,comm事件发生时,增加对comm的更新和符号信息的更新,用以匹配正确的数据
