BUG: FLUSHDB and QWATCH

[apoorvyadav1111]

Hi everyone,

One observation while working on DBSIZE command is when FLUSHDB is executed before QWATCH, the server does not respond further. I will be adding detailed CLI steps soon to reproduce this issue.

Edit: Replication Steps:

1. Pull latest master
2. Run server locally
3. Run either redis-cli -p 7379 or dice-cli for setting values, lets say terminal 1
4. Run dicedb-cli (important for Qwatch / subscribe), lets say terminal 2
5. While running the three terminals, run following commands in order.

SETUP:

in terminal 2:
subscribe 'SELECT $key, $value WHERE $key like "match:10?:*" ORDER BY $value desc LIMIT 3'

GET Updates:

in terminal 1:

SET match:100:user:1 23

Simultaneously, terminal 2 should update with following result:

qwatch    from SELECT $key, $value WHERE $key like 'match:10?:*' ORDER BY $value desc LIMIT 3: [['match:100:user:1', '23']]

Try setting new values in terminal 2 if you would like and terminal 1 will update with new values.

BUG

Run the following command in terminal 1

FLUSHDB

Now trying setting new values in terminal 2, but this time around terminal 2 will not receive any new update

Please assign this issue to me.
