From 15c45c745872af43df08c60979476520165a1df1 Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Fri, 20 Jun 2025 09:15:44 +0200 Subject: refs/files: skip updates with errors in batched updates The commit 23fc8e4f61 (refs: implement batch reference update support, 2025-04-08) introduced support for batched reference updates. This allows users to batch updates together, while allowing some of the updates to fail. Under the hood, batched updates use the reference transaction mechanism. Each update which fails is marked as such. Any failed updates must be skipped over in the rest of the code, as they wouldn't apply any more. In two of the loops within 'files_transaction_finish()' of the files backend, the failed updates aren't skipped over. This can cause a SEGFAULT otherwise. Add the missing skips and a test to validate the same.
