The TXT record concatenates and outputs all character strings #259
Comments

Ah yes. This code was based on a misunderstanding of mine assuming that the purpose of a sequence of multiple character strings in a TXT record was so they could be longer than 255 characters. I suppose it shouldn’t be quoted if it is just a single character string, though? |
|
Looks like dig quotes it anyway. We’ll do the same, then. |
Additionally, space in the current TXT records will not be escaped. the current implementation will output them as \32. |
|
I noticed this now as I was writing test cases for a fix. |

Breaking changes * All types and functions referring to domain names have been changed from using the term “dname” to just “name.” For instance, `Dname` has become `Name`, `ToDname` has become `ToName`, and `ToDname::to_dname` has become `ToName::to_name`. ([#290]) * The `ToName` and `ToRelativeName` traits have been changed to have a pair of methods a la `try_to_name` and `to_name` for octets builders with limited and unlimited buffers, reflecting the pattern used elsewhere. ([#285]) * The types for IANA-registered parameters in `base::iana` have been changed from enums to a newtypes around their underlying integer type and associated constants for the registered values. (This was really always the better way to structure this.) ([#276], [#298]) * The `Txt` record data type now rejects empty record data as invalid. As a consequence `TxtBuilder` converts an empty builder into TXT record data consisting of one empty character string which requires `TxtBuilder::finish` to be able to return an error. ([#267]) * `Txt` record data serialization has been redesigned. It now serialized as a sequence of character strings. It also deserializes from such a sequence. If supported by the format, it alternatively deserializes from a string that is broken up into 255 octet chunks if necessary. ([#268]) * The text formatting for `CharStr` has been redesigned. The `Display` impl now uses a modified version of the representation format that doesn’t escape white space but also doesn’t enclose the string in quotes. Methods for explicitly formatting in quoted and unquoted presentation format are provided. ([#270]) * The `validate::RrsigExt` trait now accepts anything that impls `AsRef<Record<..>>` to allow the use of smart pointers. ([#288] by [@hunts]) * The stub resolver now uses the new client transports. This doesn’t change how it is used but does change how it queries the configured servers. ([#215]) * The sub resolver’s server configuration `Transport` type has been changed to be either `Transport::UdpTcp` for trying UDP and if that leads to a truncated answer try TCP and `Transport::Tcp` for only trying TCP. The stub resolver uses these accordingly now ([#296]) * Many error types have been changed from enums to structs that hide internal error details. Enums have been kept for errors where distinguishing variants might be meaningful for dealing with the error. ([#277]) * Renamed `Dnskey::is_zsk` to `is_zone_key`. ([#292]) * Split RRSIG timestamp handling from `Serial` into a new type `rdata::dnssec::Timestamp`. ([#294]) * Upgraded `octseq` to 0.5. ([#257]) * The minimum Rust version is now 1.70. ([#304]) New * Add impls for `AsRef<RelativeDname<[u8]>>` and `Borrow<RelativeDname<[u8]>>` to `RelativeDname<_>`. ([#251] by [@torin-carey]) * Added `name::Chain::fmt_with_dots` to format an absolute chained name with a final dot. ([#253]) * Added a new `ParseAnyRecordData` trait for record data types that can parse any type of record data. ([#256]) * Added implementations of `OctetsFrom` and `Debug` to `AllOptData` and the specific options types that didn’t have them yet. ([#257]) * Added missing ordering impls to `ZoneRecordData`, `AllRecordData`, `Opt`, and `SvcbRdata`. ([#293]) * Added `Name::reverse_from_addr` that creates a domain name for the reverse lookup of an IP address. ([#289]) * Added `OptBuilder::clone_from` to replace the OPT record with the content of another OPT record. ([#299]) * Added `Message::for_slice_ref` that returns a `Message<&[u8]>`. ([#300]) Bug fixes * Fixed the display implementation of `name::Chain<_, _>`. ([#253]) * Fixed the display implementation of `rdata::Txt<..>`. It now displays each embedded character string separately in quoted form. ([#259]) * Fixed the extended part returned by `OptRcode::to_parts` (it was shifted by 4 bits too many) and return all 12 bits for the `Int` variant in `OptRcode::to_int`. ([#258]) * Fixed a bug in the `inplace` zonefile parser that made it reject character string of length 255. ([#284]) Unstable features * Added the module `net::client` with experimental support for client message transport, i.e., sending of requests and receiving responses as well as caching of responses. This is gated by the `unstable-client-transport` feature. ([#215],[#275]) * Added the module `net::server` with experimental support for server transports, processing requests through a middleware chain and a service trait. This is gated by the `unstable-server-transport` feature. ([#274]) * Added the module `zonetree` providing basic traits representing a collection of zones and their data. The `zonetree::in_memory` module provides an in-memory implementation. The `zonetree::parsed` module provides a way to classify RRsets before inserting them into a tree. This is gated by the `unstable-zonetree` feature. ([#286])

If the TXT record is
"aaa" "bbb", it should be output as"aaa" "bbb"rather than concatenating asaaabbb.Should add
