From 3adba736620c85112e0f9f6d043d3574e1c5830f Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Mon, 25 Aug 2014 15:33:17 -0400 Subject: [PATCH] Revert XactLockTableWait context setup in conditional multixact wait There's no point in setting up a context error callback when doing conditional lock acquisition, because we never actually wait and so the user wouldn't be able to see the context message anywhere. In fact, this is more in line with what ConditionalXactLockTableWait is doing. Backpatch to 9.4, where this was added. --- src/backend/access/heap/heapam.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) diff --git a/src/backend/access/heap/heapam.c b/src/backend/access/heap/heapam.c index 5141fcab7a..4d7575bc06 100644 --- a/src/backend/access/heap/heapam.c +++ b/src/backend/access/heap/heapam.c @@ -109,8 +109,7 @@ static void MultiXactIdWait(MultiXactId multi, MultiXactStatus status, uint16 in Relation rel, ItemPointer ctid, XLTW_Oper oper, int *remaining); static bool ConditionalMultiXactIdWait(MultiXactId multi, MultiXactStatus status, - uint16 infomask, Relation rel, ItemPointer ctid, - XLTW_Oper oper, int *remaining); + uint16 infomask, Relation rel, int *remaining); static XLogRecPtr log_heap_new_cid(Relation relation, HeapTuple tup); static HeapTuple ExtractReplicaIdentity(Relation rel, HeapTuple tup, bool key_modified, bool *copy); @@ -4438,8 +4437,7 @@ l3: { if (!ConditionalMultiXactIdWait((MultiXactId) xwait, status, infomask, relation, - &tuple->t_data->t_ctid, - XLTW_Lock, NULL)) + NULL)) ereport(ERROR, (errcode(ERRCODE_LOCK_NOT_AVAILABLE), errmsg("could not obtain lock on row in relation \"%s\"", @@ -6246,11 +6244,10 @@ MultiXactIdWait(MultiXactId multi, MultiXactStatus status, uint16 infomask, */ static bool ConditionalMultiXactIdWait(MultiXactId multi, MultiXactStatus status, - uint16 infomask, Relation rel, ItemPointer ctid, - XLTW_Oper oper, int *remaining) + uint16 infomask, Relation rel, int *remaining) { return Do_MultiXactIdWait(multi, status, infomask, true, - rel, ctid, oper, remaining); + rel, NULL, XLTW_None, remaining); } /*
