Sachin, salute!
The patch looks good, but I think it misses some verbosity in few places, please read on.

What was a problem at the above point? [Anything that you think may not be straightforward for a patch reader is always worth to highlight in the description.]
Added a comment in code. Earlier it was unable to parse replication filter with connection name

To the test part, I suggest we always follow a well-know description pattern (which is a great time saver when it comes to future test maintenance, apart from the current reviewing), to include the task id (present in the name though) and title, what failed and *how* the test proves the fixes.
Sorry , Corrected.
I can bet the failure was also exposed by reset @@global.'connection_name'.'rule_type' variables, which the test is really missing. Could you please add up that?
Right, Done

When the test proves something via printing out, it's always good to prepare the output with an
--echo what-is-expected
Done, Sorry

Naturally, the same applies to the following block.
