Debug logging of ConnectionWatchdog has wrong prefix after reconnect.

[mlex]

All ConnectionWatchdog debug logs are prefixed with a channel descriptor. This prefix is stored in the logPrefix field.

After a reconnect, the logPrefix is not updated, which leads to rather confusing log messages, because the channel descriptor in the log message does not represent the actually active channel.

For example in the following log message the current channel is actually /10.255.101.203:41124 -> /10.255.94.48:6381 while the log prefix shows /10.255.101.203:33545 -> /10.255.94.48:6381:

R:/10.255.94.48:6381]))

We found this bug in version 3.4.2.Final, but it is probably still relevant for latest SNAPSHOT.

Thanks for the bug report. Please note that Lettuce 3.x isn't maintained anymore. Please upgrade to Lettuce 4 or 5.

Sorry, I meant 4.4.0.Final. My fault.

[mp911de]

That's fixed now.
