---------------------------------------
Summary: Support character ranges in Kafka shell globs
Key: KAFKA-20642
URL: https://issues.apache.org/jira/browse/KAFKA-20642
Project: Kafka
Issue Type: Improvement
Components: tools
Reporter: Jheng-Sing Chen
Assignee: Jheng-Sing Chen
Kafka shell glob matching currently supports `*`, `?`, and `\{a,b}` groups in
GlobComponent, but character classes/ranges are not implemented.
GlobComponent.java contains a TODO for this:
// TODO: handle character ranges
As a result, glob patterns such as:
topic-[0-9]
topic-[abc]
topic-[!abc]
are not interpreted as character classes/ranges.
Expected behavior:
topic-[0-9] should match topic-0, topic-1, ..., topic-9
topic-[0-9] should not match topic-a or topic-10
topic-[abc] should match topic-a, topic-b, and topic-c
topic-[!abc] should match a single character other than a, b, or c
This can likely be addressed in org.apache.kafka.shell.glob.GlobComponent by
translating glob character classes into equivalent Java regular expression
character classes, with tests added to GlobComponentTest.
