From ddcee9432bbd5b33c790b0027ab6f7258376e980 Mon Sep 17 00:00:00 2001 From: Ashutosh Bapat Date: Thu, 13 Aug 2026 17:24:15 +0530 Subject: [PATCH v20260813 1/3] Make generate_queries_for_path_pattern_recurse() interruptible In case of a very long path pattern with each element pattern being resolved to many graph elements generate_queries_for_path_pattern_recurse() may take very long time to generate all the possible graph paths. Make generate_queries_for_path_pattern_recurse() interruptible so that a user may be able to cancel such a query if required and the interrupts are processed in timely manner.
