189-189: LGTM! Addition ofDoBinlogByDBmethod.The new method
DoBinlogByDBis well-named and fits within the context of the class.
194-194: LGTM! Addition ofDoFlushCachemethod.The new method
DoFlushCacheis well-named and fits within the context of the class.
196-196: LGTM! Addition ofToRedisProtocolmethod.The new method
ToRedisProtocolis well-named and fits within the context of the class.src/pika_admin.cc (5)
535-538: LGTM! The function renaming is clear and appropriate.The renaming of
DoUpdateCachetoDoFlushCacheaccurately reflects its functionality of clearing the cache.
600-606: LGTM! The changes improve granularity in binlog handling.The
DoBinlogmethod now iterates over all databases and callsDoBinlogByDBfor each, ensuring individual processing.
611-621: LGTM! The function correctly constructs a Redis protocol command.The
ToRedisProtocolmethod prepares a string that represents the command in the Redis protocol format.
Line range hint
548-569:
LGTM! The function correctly handles the flush operation.The
Domethod locks the databases, performs the flush operation, and then unlocks the databases, ensuring proper handling.
574-598: LGTM! But verify the function usage in the codebase.The
DoBinlogByDBmethod is well-implemented with appropriate error handling and logging.However, ensure that all function calls to
DoBinlogByDBmatch the expected usage.Verification successful
Function usage verified
The function
DoBinlogByDBis used correctly in the codebase, matching the expected usage pattern.
src/pika_admin.cc: The function is called withg_pika_rm->GetSyncMasterDBByName(info)as an argument, which aligns with the function's signature and intended use.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify all function calls to `DoBinlogByDB` match the expected usage. # Test: Search for the function usage. Expect: Only occurrences of the new signature. rg --type cpp -A 5 $'DoBinlogByDB'Length of output: 1066
PR #2808 已经对flushdb的主从不一致问题做了妥善处理，对于flushall命令面临的相同问题，直接将其binlog分裂为多条flushdb命令即可解决。
本PR让flushall命令写flushdb为binlog，如果是多DB状态，就每个DB分别写一条。
Ask the flushall command to write flushdb as binlog. If the flushDB status is multiple DB, write one for each DB.
