* Add dns.resolver.resolve_name(). (#903)Brian Wellington2023-03-101-0/+28
| | | | | | | | | | | | | * Add dns.resolver.resolve_name(). * Add missing type annotations. * Add async resolve_name(). * Replace List[Answer] with HostAnswers. * Switch addresses_and_families() tuple order * Fix comment.
* Resolver "nameserver" object support. (#897)Bob Halley2023-02-251-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | * Resolver "nameserver" object support. This turns the list of nameserver strings in the resolver into a tuple of nameserver objects, which abstract away making queries to a nameserver of a given type. The resolver's legacy nameserver list is "enriched" into a tuple of nameserver objects whenever it is set. Note that you cannot mutate the object other than by setting, e.g. res.nameservers.append("1.2.3.4") will not work. Error message accumulation has been updated to refer to the nameservers using a descriptive text form. * doco fix * more doco fixes * do enrichment at Resolution time * require a later mypy, fix type issues * add nameserver doc

* Use the selectors module.Brian Wellington2020-07-171-9/+9
| | | | | | Previously, there was code to either use select.select or select.poll, depending on OS. This changes it to use the selectors module, using either SelectSelector or PollSelector, but sharing code otherwise.

| | | | | | | | | | | - When no port is specified, pick the same port for UDP and TCP, so that TCP fallback can be tested. - Change handlers to get a single Request object instead of individual parameters. The Request object contains the message, peer, and connection_type previously passed, and also adds the local address and wire format message. Additionally, it provides convenient properties for accessing the question.
