Example Analysis of Redis Source Code

This article mainly introduces "Redis source code example analysis". In daily operation, I believe many people have doubts about Redis source code example analysis. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "Redis source code example analysis". Next, please follow the editor to study!

A total of 5 changes have been made.

1) in the saveDb (char * filename) function

If (fwrite (sval,sdslen (sval), 1je FP) = = 0) goto werr;VSif (sdslen (sval) & & fwrite (sval,sdslen (sval), 1m FP) = = 0) goto werr; adds a length check

2) in the saveDb (char * filename) function

If (fwrite (eleobj- > ptr,sdslen (eleobj- > ptr), 1Magna FP) = = 0) goto werr;VS if (sdslen (eleobj- > ptr) & & fwrite (eleobj- > ptr,sdslen (eleobj- > ptr), 1Magna FP) = = 0) goto werr; adds length check

3) in the saveDb (char * filename) function

RedisLog (REDIS_WARNING, "Error saving DB on disk:% s", strerror (errno)); VSredisLog (REDIS_WARNING, "Write error saving DB on disk:% s", strerror (errno))

4) in the loadDb (char * filename) function

If (fread (val,vlen,1,fp) = = 0) goto eoferr;VSif (vlen & & fread (val,vlen,1,fp) = = 0) goto eoferr; added length check

5) in the loadDb (char * filename) function

If (fread (val,vlen,1,fp) = = 0) goto eoferr;VSif (vlen & & fread (val,vlen,1,fp) = = 0) goto eoferr; still increases the length check to this point, and the study of "Redis source code example analysis" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
