This is an abstract class that implements record search logic. To create a functional resolver, subclass it and override the L{loadFile} method. @ivar _ADDITIONAL_PROCESSING_TYPES: Record types for which additional processing will be done. @ivar _ADDRESS_TYPES: Record types which are useful for inclusion in the additional section generated during additional processing. @ivar soa: A 2-tuple containing the SOA domain name as a L{bytes} and a L{dns.Record_SOA}. @ivar records: A mapping of domains (as lowercased L{bytes}) to records. @type records: L{dict} with L{bytes} keys Nc C s t j�| � | �|� i | _d S �N)r � ResolverBase�__init__�loadFile�_cache��selfr r r r r# V s zFileAuthority.__init__c C s || _ d S r! )�__dict__)r' �stater r r � __setstate__[ s zFileAuthority.__setstate__c C s dS )ab Load DNS records from a file. This method populates the I{soa} and I{records} attributes. It must be overridden in a subclass.

Essentially, implement RFC 1034 section 4.3.2 step 6. @param answer: A L{list} of the records which will be included in the I{answer} section of the response. @param authority: A L{list} of the records which will be included in the I{authority} section of the response. @param ttl: The default TTL for records for which this is not otherwise specified. @return: A generator of L{dns.RRHeader} instances for inclusion in the I{additional} section.

Only I{IN} is implemented here and this value is presently disregarded. @type cls: L{int} @param type: The type of records being queried. See the types defined in L{twisted.names.dns}. @type type: L{int} @param timeout: All processing is done locally and a result is available immediately, so the timeout value is ignored. @return: A L{Deferred} that fires with a L{tuple} of three sets of response records (to comprise the I{answer}, I{authority}, and I{additional} sections of a DNS response) or with a L{Failure} if there is a problem processing the query. r Nr Fr+ T) �max�soa�minimum�expirer1 r2 r3 r8 r4 r �NS�appendr6 r7 Z ALL_RECORDS�CNAMEr< �extend�SOAr �succeedZ_isSubdomainOf�failr �FailureZAuthoritativeDomainErrorr � DomainError)r' r0 �clsr- �timeoutZcnames�resultsr9 � additional� default_ttlZdomain_recordsr: r8 ZadditionalInformationr r r �_lookup� sR "�� �� ��zFileAuthority._lookup� c C s t �|�}| jd �� |�� k�rt| jd j| jd j�}| jd jd urZ| jd j}n|}t j| jd t j t j || jd dd�g}| j � � D ]T\}}|D ]F}|jd ur�|j} n|} |j t j kr�|�t j||j t j | |dd�� q�q�|�|d � t�|ddf�S t�t�t �|���S )Nr r Tr+ r )r � domainStringr> r3 r= r? r@ r8 r6 rE r7 r1 �itemsr4 rB r rF rG r rH rI ) r' r0 rK rN Zsoa_ttlrL �k�rr; r8 r r r � lookupZone� s, �� �zFileAuthority.lookupZonec C sb g g g }}}|D ]B}|d r|� |d d � |� |d d � |� |d d � q|||fS )Nr r � )rD )r' rL Zansr, �add�resr r r � _cbAllRecords� s zFileAuthority._cbAllRecords)N)rP )�__name__� __module__� __qualname__�__doc__r rC ZMXrA r. �AZAAAAr5 r> r1 r# r* r$ r< rO rU rY r r r r r ; s Y r c @ s( e Zd ZdZdd� Zdd� Zdd� ZdS ) �PySourceAuthorityzC A FileAuthority that is built up from Python source code. c C s| | � � i }}t|||� d|vr.td| ��i | _|d D ]:}t|d tj�rV|| _| j�|d � � g �� |d � q<d S )N�zonezNo zone defined in r r ) �setupConfigNamespacer � ValueErrorr1 � isinstancer Z Record_SOAr> � setdefaultr3 rB )r' r �g�lZrrr r r r$ s zPySourceAuthority.loadFilec s � fdd�}|S )Nc s t �| �� |i |��fS r! )r rQ )r0 �arg�kw�r- r r �wrapRecordFunc s z4PySourceAuthority.wrapRecord.<locals>.wrapRecordFuncr )r' r- rj r ri r � wrapRecord s z PySourceAuthority.wrapRecordc C sN i }t j�� }dd� |D �D ],}tt |�}| �|�}|||td�d � < q |S )Nc S s g | ]}|� d �r|�qS )�Record_)� startswith)�.0�xr r r � <listcomp>" � z:PySourceAuthority.setupConfigNamespace.<locals>.<listcomp>rl )r r( �keys�getattrrk �len)r' rT rR r: r- r r r r ra s z&PySourceAuthority.setupConfigNamespaceN)rZ r[ r\ r] r$ rk ra r r r r r_ s r_ c @ sH e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dS )� BindAuthorityz� An Authority that loads U{BIND zone files <https://en.wikipedia.org/wiki/Zone_file>}.
