---------------------------------
Summary: ExpressionMessageFilter will pass some message
Key: ROCKETMQ-284
URL: https://issues.apache.org/jira/browse/ROCKETMQ-284
Project: Apache RocketMQ
Issue Type: Bug
Components: rocketmq-broker
Affects Versions: 4.1.0-incubating
Reporter: Eric Liu
Assignee: Eric Liu
Fix For: 4.2.0-incubating
ExpressionMessageFilter will pass some message with tag's hash code less than 0.
This is not correct. After sql filter feature added, the tag's hash code in
consume queue may be replaced by the address of consume queue ext. And,
differences between them are:
1. Tag's hash code is an integer, values is between Integer.MIN and Integer.MAX.
2. Address of consume queue ext is a long, values is between Long.MIN and
Integer.MIN - 1.
So, actually, they are not conflict.
