Subject: [PATCH] Correct add_update_server losing first unmarked entries
|
||
|
|
||
|
Beginning of servers list were updated when first server(s) record is
|
||
|
not marked. That was a mistake, which forgot updating also up pointer to
|
||
|
correct value. Move that loop to separate reuse_server function, which
|
||
|
is close to similar loop in cleanup_servers. Makes it easier to compare
|
||
|
and do correct. Removed tmp variable, because this code does not
|
||
|
invalidate previous serv pointer.
|
||
|
|

|
