export_bind_zone_file diverged from the AXFR path in four ways, each a
bug:
- It iterated nb_zone.records.all(), including inactive records, whereas
the AXFR handler filtered Record.objects.filter(zone=nb_zone,
active=True). Exported zone files could contain stale/withdrawn
records.
- It passed record.ttl straight to rdataset.add(), crashing with a
TypeError when the NetBox DNS Record had no TTL set. The AXFR path
used 'ttl = record.ttl or nb_zone.default_ttl'.
- It had no TXT quoting logic, so TXT values containing spaces or
semicolons were mis-tokenized by dns.rdata.from_text (a ';' was
treated as the start of a comment). The AXFR path quotes and chunks
TXT values for exactly this reason.
- It appended a fresh rdataset to the node for every record instead of
merging records that share a name and type, producing duplicate
rdatasets and malformed zone files.
Extract build_dns_zone(nb_zone) in utils.py containing the corrected,
AXFR-proven record-building logic (active filter, TTL fallback, TXT
quoting/chunking, rdataset merging via rdatasets_dict). Rewrite
export_bind_zone_file to build the zone through build_dns_zone and then
write it. Rewrite request_handler._get_zone_from_nb to look up the
NetBox DNS Zone and delegate to build_dns_zone, keeping only the
DoesNotExist/OperationalError handling that is specific to the query
path.
Both code paths now produce identical zone data.
_getZoneFromNB was the only camelCase function in the codebase,
inconsistent with the snake_case convention used everywhere else.
Rename it and update its callers and the adjacent comment.
Pure rename, no behavior change.
The logging call passed the exception as a positional argument with no
%s placeholder in the format string:
LOGGER.error("Error parsing query: ", e)
Python's logging applies msg % args, which raised TypeError (not all
arguments converted during string formatting) inside logging.handleError.
The logging framework swallows that secondary error, so neither the
intended message nor the exception was ever recorded.
Use an f-string so the exception is actually rendered and logged.

Range of bug fixes and improvements
modified: netbox_dns_bridge/signals/netbox_dns_zones.py
1. On zone deletion the catalog zone serial was not incremented, causing clients
not to delete the zone until another zone is created/modified. Fixed using
post_delete signal.
2. Even with the notify_clients feature disabled, the client IPs were still
being tracked. This disables the unnecessary behavior.
3. _track_seen_client function in DNSBaseRequestHandler did not have the 'self'
reference parameter, causing calls to fail. Fixed.

Disable NOTIFY feature by default and add setting to enable it.
modified: netbox_dns_bridge/request_handler.py
modified: netbox_dns_bridge/utils.py
Various little bug fixes. Analysed by AI but fixed by hand to ensure integrity.
Fix paths after restructuring
renamed: netbox_dns_bridge/management/commands/export-dns-zone.py -> netbox_dns_bridge/management/commands/dns-export-zone.py
renamed: netbox_dns_bridge/management/commands/export-all-dns-zones.py -> netbox_dns_bridge/management/commands/dns-export-zones.py
Unify command naming scheme
new file: netbox_dns_bridge/migrations/0001_initial.py
Adds the missing migration. Since the plugin was renamed this is also an opportunity to merge all changes into a single migration.
renamed: netbox_dns_bridge/service/transfer/catalog_zone_manager.py -> netbox_dns_bridge/catalog_zone_manager.py
renamed: netbox_dns_bridge/service/transfer/dns_server.py -> netbox_dns_bridge/dns_server.py
new file: netbox_dns_bridge/management/commands/dns-settings.py
modified: netbox_dns_bridge/management/commands/dns-transfer-endpoint.py
renamed: netbox_dns_bridge/service/transfer/request_handler.py -> netbox_dns_bridge/request_handler.py
deleted: netbox_dns_bridge/service/transfer/__init__.py
Another restructure to simplify code re-use. New command dns-settings added to allow setting of catalog zone serial.
This will be needed to migrate from previous versions.
