* Attempt to refactor per-opcode validation.messageBrian Wellington2020-06-261-43/+28
| | | | | | | | Instead of validating rrsets and sections after parsing them, check the class/type for each record before parsing it. This is more generic, because it moves all of the update logic out of the common code. It's also more flexible, as it allows the update logic to specify that meta-records are empty.
* Remove hardcoded section names from TextReader.Brian Wellington2020-06-261-26/+36
|
* Minor _WireReader refactoring.Brian Wellington2020-06-261-47/+49
| | | | | | Instead of parsing the header to determine which Message subclass to create and passing that message to _WireReader, make _WireReader create the Message subclass itself.

* Fix TTL limiting.Brian Wellington2020-06-241-1/+1
| | | | | | | | The message code would convert negative TTL into 0, but the TTL could never be negative, as it was read with the '!I' format, which reads unsigned 32 bit integers. We don't want to change that, since OPT flags (which are encoded in the TTL) should be treated as unsigned. Instead, treat all TTLs > (2^31 - 1) as 0.
* Minor style changes.Brian Wellington2020-06-241-9/+8
| | | | | There's no need to pass start=0 to range(). Use += when possible. Replace multiple comparisons with in.

* Add support for multi-message TSIG.Brian Wellington2020-06-161-5/+19
| | | | | The underlying renderer code supported this, but it was not exposed through message.to_wire().

* Minor Python 3 cleanups.Brian Wellington2020-06-031-3/+3
| | | | | | | Classes inherit from object by default; there's no need to explicitly include this. Replace super(Foo, self) with super().

* Remove dns.rdata{type,class}.to_enum.Brian Wellington2020-05-211-2/+2
| | | | | | | These methods (which convert a str/int into an enum/int) shouldn't be commonly used by external code, so don't need to exist at the module level. The make() method on the enum class (renamed from to_enum()) can still be used, and the internal callers have been updated to use it.
* Start converting rdatatype/rdataclass to enum.Brian Wellington2020-05-181-4/+2
|
* Fix the dns.message.BadEDNS documentation.Brian Wellington2020-05-111-1/+1
| | | | | The OPT record isn't required to be at the start of the additional section, and the code doesn't enforce that.

* Use context managers to simplify code.Brian Wellington2020-05-011-15/+5
| | | | | | | | Simplify code using try/finally to use context managers. In some cases, contextlib.ExitStack() is used; this could probably be further simplified to use contextlib.nullcontext() once Python 3.7+ is a requirement.

* Correct Message.is_response docstringPeter Olson2020-02-291-1/+1
| | | | | When testing responses, I discovered that the docstring for Message.is_response had the comparison backwards, specifically in how the `QR` flag is checked. The documentation was incorrectly updated in fc7db7da4284eedaa951e6acc34e6e6f94da1c64
