There was a problem hiding this comment.
I moved this handler to be right below the onDatabaseChange event handler for better ordering and to keep the event next to all of the other ENVCHANGE events.

This PR is to fix #1669, where the library throws an unhandled exception if it encounters an
ENVCHANGEevent of typeDATABASE_MIRRORING_PARTNER.This behavior isn't explicitly documented, but there have been a few issues brought up regarding this functionality in the past, and it has been stated that tedious does not plan to support failover partners. While that may be the case, this event being emitted by SQL Server is causing Tedious to crash completely rather than simply ignoring it as you would expect.
The changes in this PR are to create the
databaseMirroringPartnerevent emitter and register the necessary handler methods in the associated token handler classes, to prevent the default behavior of throwing anUnexpected tokenerror.To clarify, this does not implement mirroring functionality or anything of the sort, it simply updates the default behavior to allow the event to pass through and be ignored, rather than unnecessarily throwing an unhandled exception.
