I add some log to
/usr/local/apisix//deps/share/lua/5.1/resty/dns/client.lua:asyncQuery
`local function asyncQuery(qname, r_opts, try_list)
local key = qname..":"..r_opts.qtype
local item = queue[key]
if item then
--[[
log(DEBUG, PREFIX, "Query async (exists): ", key, " ", fquery(item))
--]]
try_status(try_list, "in progress (async)")
return item-- already in progress, return existing query
end
-- log
local nil_qtype = false
if r_opts.qtype == nil then
nil_qtype = true
end
item = {
key = key,
semaphore = semaphore(),
qname = qname,
r_opts = deepcopy(r_opts),
try_list = try_list,
}
-- log
if item.r_opts.qtype == nil or nil_qtype then
log(ERR, PREFIX, "item nil qtype in async, ", nil_qtype, " item ropts,
",json(item.r_opts), " key=", key, "try list=", tostring(try_list))
end
queue[key] = item
local ok, err = timer_at(0, executeQuery, item)
if not ok then
queue[key] = nil
log(ERR, PREFIX, "Failed to create a timer: ", err)
return nil, "asyncQuery failed to create timer: "..err
end
--[[
log(DEBUG, PREFIX, "Query async (scheduled): ", key, " ", fquery(item))
--]]
try_status(try_list, "scheduled")
return item
end
`
and the error logs is
`item nil qtype in async, false item ropts, {} key=***.rds.aliyuncs.com:1try
list=["(short)***.rds.aliyuncs.com:(na) -
cache-hit/stale","***.rds.aliyuncs.com.test-back.svc.cluster.local:1 -
