From 1be94440d38ad6af64486ce31c650d0540d4049c Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Wed, 25 Jul 2018 11:01:36 +0100 Subject: [PATCH] Fix occasional 'tuple index out of range' error This fixes a bug in _delete_existing_rows_txn which was introduced in #3435 (though it's been on matrix-org-hotfixes for *years*). This code is only called when there is some sort of conflict the first time we try to persist an event, so it only happens rarely. Still, the exceptions are annoying. --- changelog.d/3607.bugfix | 1 + synapse/storage/events.py | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) create mode 100644 changelog.d/3607.bugfix diff --git a/changelog.d/3607.bugfix b/changelog.d/3607.bugfix new file mode 100644 index 0000000000..7ad64593b8 --- /dev/null +++ b/changelog.d/3607.bugfix @@ -0,0 +1 @@ +Fix 'tuple index out of range' error \ No newline at end of file diff --git a/synapse/storage/events.py b/synapse/storage/events.py index 906a405031..f7c4226ea2 100644 --- a/synapse/storage/events.py +++ b/synapse/storage/events.py @@ -1137,7 +1137,7 @@ class EventsStore(EventsWorkerStore): ): txn.executemany( "DELETE FROM %s WHERE room_id = ?
