From 1124a10f9780d4bd3df256e1663ac2b2eb804573 Mon Sep 17 00:00:00 2001 From: Alessio Podda Date: Sat, 25 Oct 2025 11:01:27 +0200 Subject: [PATCH 1/9] Clean up ixfr transaction API Make the API tighter. The idea of this commit is to highlight the distinction between a database transaction and a journal transaction, and ensure we run dns_zone_verifydb on error. Done to simplify a later refactor.

We do this in three steps: - We extend dns_rdatacallbacks_t vtable to allow subtraction and resigning. - We add a new set of api (begin|commit|abort)update to the dbmethods vtable, that model an incremental update that can be aborted. - We extract the core logic of diff_apply into a function that satisfies the new interface. - We make diff_apply use this new function, and log the results. The intent of this commit is to allow databases to expose a batch incremental update implementation, just like they expose a custom batch creation implementation through (begin|end)load.
