I looked through 224 locations where SpinLockAcquire and found some. LogicalIncreaseRestartDecodingForSlot is spotted by Michael. pg_get_replication_slots has some namecpy as Tom pointed out. copy_replication_slot has pstrdup as Tom pointed out. InvalidateObsoleteReplicationSlots has pstrdup as Tom poineed out. I found another instance of pstrdup, but found some string copy functions. CreateInitDecodingContext has StrNCpy (up to NAMEDATALEN = 64 bytes). RequestXLogStreaming has strlcpy (up to MAXCONNINFO = 1024 bytes). SaveSlotToPath has memcpy on ReplicationSlotOnDisk (176 bytes). WalReceiverMain has strlcpy(MAXCONINFO + NAMEDATALEN) and memset of MAXCONNINFO. pg_stat_get_wal_receiver has strlcpy (NAMEDATALEN + NI_MAXHOST(1025) + MAXCONNINFO). regards. -- Kyotaro Horiguchi NTT Open Source Software Center
