3741. [func] "delve" (domain entity lookup and validation engine):
A new tool with dig-like semantics for performing DNS
lookups, with internal DNSSEC validation, using the
same resolver and validator logic as named. This
allows easy validation of DNSSEC data in environments
with untrustworthy resolvers, and assists with
troubleshooting of DNSSEC problems. (Note: not yet
available on win32.) [RT #32406]
on a missing resolv.conf file and initializes the
structure as if it had been configured with:
nameserver ::1
nameserver 127.0.0.1
Note: Callers will need to be updated to treat
ISC_R_FILENOTFOUND as a qualified success or else
they will leak memory. The following code fragment
will work with both only and new versions without
changing the behaviour of the existing code.
resconf = NULL;
result = irs_resconf_load(mctx, "/etc/resolv.conf",
&resconf);
if (result != ISC_SUCCESS) {
if (resconf != NULL)
irs_resconf_destroy(&resconf);
....
}
