* Remove dns.rdata{type,class}.to_enum.Brian Wellington2020-05-211-10/+10
| | | | | | | 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.

| | | | | | | | 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.

|\ | | | | zone.to_text() should return a string.
| * zone.to_text() should return a string.Brian Wellington2020-03-201-2/+2
| | | | | | | | | | | | As part of the Python 3 conversion, the result of dns.zone.to_text() changed from str to bytes. This was likely unintentional, as a method with text in its name should be returning text.
* | Add relativize_to to from_text().Brian Wellington2020-03-181-4/+4
|/ | | | | | | | | | | | | | | When calling from_text, the zone code needs to apply the current origin (which may or may not be the zone origin, if sub-zone $ORIGIN statements are present), and may also want to relativize the contents to the zone origin. Previously, this was done by explicitly reading records as absolute, and then relativizing them laster. With this change, the work is moved to the tokenizer. This gets rid of the remaining internal uses of dns.rdata.choose_relativity(), which prevents rdata from being immutable.
* Remove choose_relativity() from zone.from_xfr()Brian Wellington2020-03-181-1/+0
| | | | | | | | | | The comment states that relativize must be consistent between dns.query.xfr() and dns.zone.from_xfr(), and the code fails if they're not (if check_origin is True, at least). This means that the rdata is already correctly relativized (or not). This also adds a test of creating zones from xfrs, both relativized and not.

* Update zone.pytmerila2019-04-031-3/+3
| | | Check for self.last_ttl_known before setting ttl = self.last_ttl so it will remain None instead of 0 if value is not known.
* Update zone.pytmerila2019-04-031-1/+1
| | | Need to also check that last TTL is known before using it as a fallback, otherwise ttl is never None in the last check, setting it incorrectly to 0 instead.
* Update zone.pytmerila2019-04-031-12/+21
| | | Instead of moving the entire TTL parsing past the rdata handling (causing the RR to be parsed on the wrong way), returned the parsing to its original location, and only moved the final failure code past the rdata handling.
* Update zone.pytmerila2019-04-031-15/+17
| | | By doing the TTL validity check after parsing the record data allows the TTL to be set properly from SOA RDATA even when the SOA record itself does not have TTL set.
* $GENERATE was not padding correctly given a pattern like ${0,3} it wasBob Halley2019-02-211-1/+0
| | | | | using the index field (0) as the padding width, instead of the correct value 3.

| * Improve TTL detection when reading master zone files.Tom Lanyon2017-05-311-10/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces the same behaviour that BIND has when it encounters implicit TTL values, namely: * The $TTL directive is preferred to set the default TTL [RFC2308]. * If no $TTL directive is seen prior to the SOA RR, the default TTL is set to the minimum TTL field of the SOA RR [RFC1033, RFC1035, RFC1912]. * If neither $TTL nor an SOA are present, use the last seen explicit TTL on an RR or raise a SyntaxError if no explicit TTLs have been seen. Previously, when neither $TTL nor SOA were present, the TTL for an RR without an explicit TTL would be set to 0 which is known to be a somewhat dangerous value and shouldn't be encouraged as a default. One test seems to rely on this default TTL=0 behaviour whilst testing something seemingly unrelated (RR starting with whitespace), so that test has been updated to match this new expectation. Fixes #254.
