jsimonet/dns-zone

Parse a DNS zone file, and give ability to add/modify/remove some entries.

What

A tool providing an easy way to manage a DNS file zone.

Why

For fun, because similar modules already exists in Perl 5. I wanted to use Perl 6 to discover the language, and to learn with a concrete project.

How

Grammar

The main part of this project is to write a grammar for parsing a DNS zone file. As a result, we will obtain an AST "DNSZone" object, representing the content of this file.

AST

This object will contains methods to add, update and remove an entry.

The last step is to write a new zone file based on the new AST.

dns-zone's Issues

Will no longer be updated to the Raku ecosystem

Hello,

Thank you for the time and effort you have put in what is now the Raku Programming Language. The language and its ecosystem are moving forward.

This means that these distributions:

• https://github.com/jsimonet/dns-zone
• https://github.com/jsimonet/IRC-Client-Plugin-UserPoints
• https://github.com/jsimonet/log-any

will no longer be checked for updates by the Raku ecosystem.

This means that you will need to move your module to the zef ecosystem on the next update you make to these distributions. Otherwise your update will simply not be seen by the ecosystem.

If you are no longer interested in maintaining these distributions, you can have these distributions moved to Raku Community Modules Adoption Center, where members of the Raku Community will take care of them.

This can be as easy as confirming that in a response to this issue.

Again, thank you for your time and efforts!

On behalf of the Raku Steering Council,

Does not work on latest Rakudo (the code is relying on buggy backtracking)

Currently the tests are failing (on all rakudos after 963a0f0657a).

The issue can be “fixed” by adding :!r here:
https://github.com/jsimonet/dns-zone/blob/master/lib/DNS/Zone/Grammars/Modern.pm6#L252-L260

That being said, I'm not sure why backtracking is needed there. There may be a better way to do it.

See RT #130117 for more info.

Should empty zone valid ?

named-checkzone does not validate it because no SOA is defined nor NS.

CurrentTTL in Modern grammar is static.

grammar Modern {
    my $currentTTL;
}

declares a static variable, and so it is shared between two grammar instances.

The following test will fails because $currentTTL is defined in the second test:

nok DNS::Zone::Grammars::Modern.parse("\$ttl 3600 domain in a 10.0.0.1");
nok DNS::Zone::Grammars::Modern.parse( 'domain in a 10.0.0.1' ); # No ttl defined

The use of attributes is not possible because they cannot be used inside regexes.
