From 6b68a4238bcd1131f49eac2958d42847295af720 Mon Sep 17 00:00:00 2001 From: Tanaydin Sirin Date: Mon, 14 Sep 2026 15:30:05 +0200 Subject: [PATCH] Fix DBMS name/version reporting fallback and resume detection Format.getDbms() now falls back to conf.dbms (and Backend.getDbms() falls back to conf.dbms as well) when kb.dbms isn't set yet, so a version-only result no longer drops the DBMS name or prints "None". _resumeDBMS() in target.py now also sets Backend's DBMS/version when resuming a session where the DBMS wasn't previously fingerprinted. Also simplifies several option.py helpers (non-SQL technique lookup, tamper priority validation, kb.chars/multibit setup) and adds unit tests for the getDbms() fallback behavior.
