UserWarning: resource_tracker: There appear to be 1 leaked shared_memory objects to clean up at shutdown"""未正确释放共享内存的程序,在程序执行之后,会发出以上警告内容。 特点 1.shared_memory的性能非常高,因为进程可以直接操作内存区域,避免了数据复制和进程间通信的开销。2.无锁,数据同步问题需要自行加...
它会在python程序退出时,自行销毁sharedMemory,即便此时还有其他的进程在使用——这会让C/Python跨进程调用几乎没有办法进行。 python程序运行完毕会弹出错误信息: UserWarning: resource_tracker: There appear to be 1 leaked shared_memory objects to clean up at shutdown 然后你定义的sharedMemory就被python随手析...

shm=SharedMemory(name="my_shared_segment",create=True,track=False) This would allow developers to specify that they do not wantresource_trackerto track this object. Allow replacingresource_trackerwith a custom implementation, so developers can define their own resource management logic. Provide an A...

For those interested in using Python3.8 's shared_memory module, it still has a bug which hasn't been fixed and is affecting Python3.8/3.9/3.10 by now (2021-01-15). The bug is about resource tracker destroys shared memory segments when other processes should still have valid access. So ...
