* Changes to blocking model.Brian Wellington2020-07-171-27/+40
| | | | | | | | | | | | | Before this change, the synchronous code would check sockets for readability or writability before doing nonblocking read or write. This changes them to attempt the read or write first, and then block if the operation could not complete. This also removes the no-longer-needed getpeername() call in tcp(), which was needed to deal with the case where an unconnected socket was passed in; waiting for writability would block rather than immediately return an error. By attempting the write first, we get the error immediately.
* Use the selectors module.Brian Wellington2020-07-171-71/+26
| | | | | | 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.
* Minor cleanups to EDNS code.Brian Wellington2020-07-171-18/+7
| | | | | | | When the Message object was changed to store an OPT record, the changes to use_edns() left a lot of cruft. Reduce some code duplication in make_query().

* Fix _wordbreak() to always return a str.Brian Wellington2020-07-091-5/+6
|
* Generalize the word breaking code.Brian Wellington2020-07-091-13/+14
| | | | | Refactor common code from _base64ify and _hexify, and also add support for _hexify to skip word breaks.
* Make dns.rdata._base64ify(..., 0) work.Brian Wellington2020-07-092-2/+4
| | | | | | | | | | In some cases, the caller absolutely doesn't want word breaks. This shouldn't be the case for any normal DNS record, but is for records that don't have well-defined text formats, like TSIG and TKEY. Allow them to pass 0 (or None), to indicate that no word breaks should be added. Previously, passing either 0 or None resulted in an exception, as the value was used directly as the step in a slice.
* Add support for receiving UDP queries.Brian Wellington2020-07-085-32/+69
| | | | | | | | | | | | | | The existing receive_udp() methods are only usable for receiving responses, as they require an expected destination and check that the message is from that destination. This change makes the expected destination (and hence the check) optional, and returns the address that the message was received from (in the sync case, this is only done if no destination is provided, for backwards compatibility). New tests are added, which required adding generic getsockname() support to the async backends.

* Move __str__ to the generic Option code.Brian Wellington2020-07-081-5/+3
| | | | | | ECSOption and GenericOption both contained a __str__ method that called to_text(), but the base Option class did not. Move __str__ to the base class.

* Consolidate NSEC/NSEC3/CSYNC bitmap handling.Brian Wellington2020-07-024-158/+103
| | | | | | | This also fixes several bugs; the NSEC3 code would properly avoid empty windows, but the NSEC and CSYNC code did not. Also, none of the wire parsing routines properly checked to see that the window number was monotonically increasing.
* Rework wire format processing.Bob Halley2020-07-0248-588/+357
| | | | | | Wire format data is now done via a dns.wire.Parser, which does all of the bookkeeping and also provides convenience routines (e.g. get_uint16() or get_name()).

|\ | | | | Add dns.tsig.Key class.
| * Better deal with backwards compatibility.Brian Wellington2020-07-012-13/+12
| | | | | | | | | | | | | | | | If dns.tsigkeyring.from_text() creates dns.tsig.Key objects with the default algorithm, that causes problems for code that specifies a different algorithm. There's no good way to handle this, so change dns.tsigkeyring.from_text() to not create dns.tsig.Key objects unless it knows the algorithm.
| * Explicitly use the key's algorithm.Brian Wellington2020-07-011-2/+2
| |
| * Add dns.tsig.Key class.Brian Wellington2020-07-016-88/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new class to represent a TSIG key, containing name, secret, and algorithm. The keyring format is changed to be {name : key}, and the methods in dns.tsigkeyring are updated to deal with old and new formats. The Message class is updated to use dns.tsig.Key, although (to avoid breaking existing code), it stores them in the keyring field. Message.use_tsig() can accept either explicit keys, or keyrings; it will extract and/or create a key. dns.message.from_wire() can accept either a key or a keyring in the keyring parameter. If passed a key, it will now raise if the TSIG record in the message was signed with a different key. If passed a keyring containing keys (as opposed to bare secrets), it will check that the TSIG record's algorithm matches that of the key.
