[GitHub] [dubbo] saleson opened a new issue, #10402: 接口级服务发现 本地缓存provider信息的cache文件与内存中的provider信息会出现不一致

saleson opened a new issue, #10402:
URL: https://github.com/apache/dubbo/issues/10402

   AbstractRegistry.doSaveProperties()虽然采用文件锁、版本号以及重试等方式对竟争场景做了处理，但是在竟争文件锁失败创建重试任务时，没有sleep，仍会有概率出现上一个版本保存操作还没有释放锁，新版本重试次数达到上限导致新版本数据没有保存到cache文件的情况。
   
   ### Environment
   
   * Dubbo version: 3.05
   * Java version: 1.8
   
   ### Steps to reproduce this issue
   
   1. 延长AbstractRegistry.doSaveProperties() 中文件锁的持有时间
   2. 在consumer中创建多个DubboService的Reference
   3. 短时间内同行时修改DubboService 的Provider侧信息
   
   
   Pls. provide [GitHub address] to reproduce this issue.
   
   ### Expected Behavior
   
   cache文件中的信息与consumer 应用内存中的Provider信息(AbstractRegistry.properties )一致
   
   ### Actual Behavior
   
   cache文件中的信息存在不致一、过时的情况，即比consumer 应用内存中的Provider信息(AbstractRegistry.properties )旧
   该情况偶现
