From e6536aa27bfdc27cad07f6c5cd3312f0f0710c96 Mon Sep 17 00:00:00 2001 From: tbordaz Date: Mon, 1 Feb 2021 09:28:25 +0100 Subject: [PATCH 3/3] Issue 4581 - A failed re-indexing leaves the database in broken state (#4582) Bug description: During reindex the numsubordinates attribute is not updated in parent entries. The consequence is that the internal counter job->numsubordinates==0. Later when indexing the ancestorid, the server can show the progression of this indexing with a ratio using job->numsubordinates==0. Division with 0 -> SIGFPE Fix description: if the numsubordinates is NULL, log a message without a division. relates: https://github.com/389ds/389-ds-base/issues/4581 Reviewed by: Pierre Rogier, Mark Reynolds, Simon Pichugin, Teko Mihinto (thanks !!)
