DEBUG command has many subcommands. For example, DEBUG set-skip-cheksum-validation 0|1, DEBUG lua-always-replicate-commands 0|1 etc. Here we want to modify the config parameters only for test purpose instead of in a real world system. |

There was a problem hiding this comment.
Suggested change

| static mstime_t sentinel_publish_period = 2000; |
I assume we want to preserve the old behavior.

This makes it possible to tune many parameters that were previously hard coded. We don't intend these to be user configurable, but only used by tests to accelerate certain conditions which would otherwise take a long time and slow down the test suite.

Because SENTINEL DEBUG missing summary in its json file, with the change in redis#10043, the following assertion will fail. ``` [redis]# src/redis-cli -p 26379 redis-cli: redis-cli.c:678: cliInitCommandHelpEntry: Assertion `reply->type == 1' failed. ``` This commit add the summary and complexity for SENTINEL DEBUG, which introduced in redis#9291, and also improved the help message.

There are two issues in SENTINEL DEBUG: 1. The error message should mention SENTINEL DEBUG 2. Add missing reuturn in args parse. ``` redis> sentinel debug INFO-PERIOD aaa (error) ERR Invalid argument 'aaa' for SENTINEL SET 'INFO-PERIOD' redis> sentinel debug a b c d (error) ERR Unknown option or number of arguments for SENTINEL SET 'a' redis> ping (error) ERR Unknown option or number of arguments for SENTINEL SET 'b' ``` Introduced in redis#9291. Also do some cleanups in the code.

For test purpose, we could change some parameters by SENTINEL DEBUG command
It is mentioned in the following 2 PR:
#8891 and #8710
The command format has 2 options:
SENTINEL DEBUG: display our current configurable parameters value
SENTINEL DEBUG [ ...]: update our current configurable parameters values (one or more)
for example: sentinel debug info-period 6000
These configurable parameters as following:
SENTINEL_INFO_PERIOD
SENTINEL_PING_PERIOD
SENTINEL_ASK_PERIOD
SENTINEL_PUBLISH_PERIOD
SENTINEL_DEFAULT_DOWN_AFTER
SENTINEL_TILT_TRIGGER
SENTINEL_TILT_PERIOD
SENTINEL_SLAVE_RECONF_TIMEOUT
SENTINEL_MIN_LINK_RECONNECT_PERIOD
SENTINEL_ELECTION_TIMEOUT
SENTINEL_SCRIPT_MAX_RUNTIME
SENTINEL_SCRIPT_RETRY_DELAY
SENTINEL_DEFAULT_FAILOVER_TIMEOUT
