Detailed Description

The transfer task.

Once done, make sure the nextprobe waiting task is running, whether done with failure or success. If failure, use shorter timeout for wait time.

◆ scan_specific

struct auth_master* auth_transfer::scan_specific

once notified, or the timeout has been reached.

a scan starts. the scan specific target (notify source), or NULL if none

◆ scan_target

struct auth_master* auth_transfer::scan_target

scan tries all the upstream masters.

the scan current target. or NULL if not working on sequential scan

◆ master

struct auth_master* auth_transfer::master

the zone transfer in progress (or NULL if in scan).

It is from this master

◆ ixfr_fail

int auth_transfer::ixfr_fail

failed ixfr transfer, retry with axfr (to the current master), the IXFR was 'REFUSED', 'SERVFAIL', 'NOTIMPL' or the contents of the IXFR did not apply cleanly (out of sync, delete of nonexistent data or add of duplicate data).

Flag is cleared once the retry with axfr is done.
