yyqdbngt opened a new pull request, #2854:
URL: https://github.com/apache/rocketmq-dashboard/pull/2854
## Summary
- Clamp `TencentInstanceProvider.toInteger` (used for topic
`writeQueues`/`readQueues`
mapping) to `Integer.MAX_VALUE` for oversized cloud values, replacing the
unguarded
`Math.toIntExact`.
- Added regression test `listTopicsShouldClampOversizedQueueCounts`.
## Why
`TopicItem.getQueueNum()` is a `Long` returned by the Tencent Cloud OpenAPI.
A value
above `Integer.MAX_VALUE` made `Math.toIntExact` throw `ArithmeticException`
during
topic listing — HTTP 500 instead of a degraded view. This was the only
unguarded
long→int conversion in the file: the sibling helpers for total counts and
retry
counts already saturate at `Integer.MAX_VALUE`, so this brings queue-count
mapping
in line with the established pattern.
## Testing
- `cd server && mvn -Dtest=TencentInstanceProviderTest test`
— Tests run: 37, Failures: 0, Errors: 0
