Secondary indexes not removed if id contains colon [DATAREDIS-744]

[spring-projects-issues]

Michał Bobowski opened DATAREDIS-744 and commented

Hello,

I've set ttl for my data using:

@RedisHash(value = "user_content", timeToLive = 60)

And enabled keyspace events by setting EnableKeyspaceEvents.ON_STARTUP.

During tests I discovered that secondary indexes are not removed after expiration and I spent couple hours on debugging. What I found was quite shocking:

• I inserted key "user_content:ipla:some7:vod:0123456789abcdef0123456789abcdef"
• Phantom key was created as well
• Key expired after TTL
• Expiration Message was generated and received by MappingExpirationListener
• Function isKeyExpirationMessage returned false and event was rejected

The reason is below:

byte[][] args = ByteUtils.split(message.getBody(), ':');
if (args.length != 2) {
  return false;
}

Message body is equal to my expiring key, therefore splitting it this way returns 6 rather than 2. Is there a hidden assumption that keys must not contain ":" sign? Or am I completely wrong about it?

Thanks for reporting the issue. That's a bug on our side – we're using colons to separate individual components from each other. Using Id's that contain colons interferes with our separators
