Fix dig error when trying the next server after a TCP connection failure (!5976) · Merge requests · ISC Open Source Projects / BIND

Arаm Sаrgsyаn requested to merge 3205-dig-tcp-next-server-on-connection-error-crash into main Mar 14, 2022

When encountering a TCP connection error while trying to initiate a connection to a server, dig erroneously cancels the lookup even when there are other server(s) to try, which results in an assertion failure.

Cancel the lookup only when there are no more queries left in the lookup's queries list (i.e. next is NULL).

Closes #3205 (closed)
