Man*_*odi 8 python segmentation-fault aerospike
我正在使用Aerospike Python CLient放置并获得一些键值对:
aerospike_dca_client.put(key,bin)
...
...
bls_key_a = (AEROSPIKE_NAMESPACE,SET_NAME,bls_key)
hp_bid_str_a = aerospike_dca_client.get(bls_key_a)[3];
#Terminates at the line above
但是在put之后,我的程序在Get命令期间以SEGFAULT终止.以下是我得到的堆栈跟踪GDB:
Program received signal SIGSEGV, Segmentation fault.

看起来像aerospike_key_get调用文件中的一些子程序src/main/aerospike/as_shm_cluster.c,这是不存在的,因此分段错误.我检查了我的$ LD_LIBRARY_PATH,它确实包含了包含的目录aerospike.so.

这已经被报告为问题112和115 塞/塞客户端的Python在GitHub回购,以及张贴在讨论区.
在您的情况下,"解决方法"是正确使用客户端.关闭与数据库的连接后,不要调用数据库.
如果你需要这个bug是固定的,你可以用叉子叉项目(它是开源的基于Apache许可证),并修复它自己,或等待该项目的维护者,以基于现有的问题自己解决它.
