[jira] [Updated] (KAFKA-2903) FileMessageSet's read method maybe
has problem when start is not zero
[ https://issues.apache.org/jira/browse/KAFKA-2903?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ismael Juma updated KAFKA-2903:
-------------------------------
Fix Version/s: (was: 0.10.1.0)
0.10.2.0
> FileMessageSet's read method maybe has problem when start is not zero

> Key: KAFKA-2903
> URL: https://issues.apache.org/jira/browse/KAFKA-2903
> Project: Kafka
> Issue Type: Bug
> Components: log
> Affects Versions: 0.8.2.1, 0.9.0.0
> Reporter: Pengwei
> Assignee: Jay Kreps
> Fix For: 0.10.2.0

>
> now the code is :
> def read(position: Int, size: Int): FileMessageSet = {
> .....
> new FileMessageSet(file,
> channel,
> start = this.start + position,
> end = math.min(this.start + position + size, sizeInBytes()))
> }
> if this.start is not 0, the end is only the FileMessageSet's size, not the actually position of end position.
> the end parameter should be:
> end = math.min(this.start + position + size, this.start+sizeInBytes())
