* net.dns: Reduce default timeout to 5sMatthew Wild2020-06-251-1/+1
| | | | | Most healthy queries will return well within this time, and the new retry logic should help spread the cost of additional retries.
* net.dns: Increase backoff delaysMatthew Wild2020-06-251-1/+1
| | | | Not entirely happy with the overall logic here.
* net.dns: Add jitter to spread queries and reduce failures due to congestionMatthew Wild2020-06-251-2/+20
|
* net.dns: Fix timeout retry logicMatthew Wild2020-06-251-16/+21
| | | | | | | On timeout the query would be resent twice - once within servfail(), and again inside the timeout callback. This commit moves all retry logic to servfail().
* net.dns: Add some debug loggingMatthew Wild2020-06-251-0/+4
|
* net.dns: Handle being loaded outside of ProsodyKim Alvefur2020-02-241-2/+2
| | | | | | `if timer ...` suggests that this was intended, but it did not work because net.timer depends on net.server which refuses to be loaded outside of Prosody.
* net.dns: Close resolv.conf handle when done (fixes #1342)Kim Alvefur2019-04-131-0/+1

| * net.dns: Syntesize type names for the full rangeKim Alvefur2018-06-091-4/+5
| | | | | | | | | | | | | | | | Otherwise unknown records are identified as A records. This also fixes various tracebacks unearthed by previous commits and mis-identified records. Related to #1056 #976 #819
| * net.dns: Don't attempt to cache unparsed data (fixes #1056)Kim Alvefur2018-06-091-1/+1
| | | | | | | | | | | | | | rr[qtype:lower()] can be nil. I think this happens if the type does not have a parser. Also see #819 #976
