From f23c3d40ca1c16f670823fab47dbac6e52576287 Mon Sep 17 00:00:00 2001 From: Duncan Coutts Date: Wed, 29 Jul 2020 01:01:18 +0100 Subject: [PATCH 1/6] Rename tables for sanity Rename TxMetadata to PoolMetadata because that is the actual pool metadata. It's nothing to do with transactions (and it's really confusing since Shelley also really does have transaction metadata). Rename PoolMetaData to PoolMetadataReference because this is _not_ the pool metadata, but the reference/pointer to the pool metadata. It has the URL and expected hash of the actual pool metadata. --- src/Cardano/Db/Error.hs | 8 ++++---- src/Cardano/Db/Insert.hs | 14 ++++++++------ src/Cardano/Db/Query.hs | 10 +++++----- src/Cardano/Db/Schema.hs | 8 ++++---- src/DB.hs | 12 ++++++------ src/DbSyncPlugin.hs | 19 +++++++++---------- 6 files changed, 36 insertions(+), 35 deletions(-) diff --git a/src/Cardano/Db/Error.hs b/src/Cardano/Db/Error.hs index f6dca40..4fa199d 100644 --- a/src/Cardano/Db/Error.hs +++ b/src/Cardano/Db/Error.hs @@ -15,7 +15,7 @@ import Data.ByteString.Char8 (ByteString) -- | Errors, not exceptions. data DBFail = DbLookupBlockHash !ByteString - | DbLookupTxMetadataHash !ByteString + | DbLookupPoolMetadataHash !ByteString | DbMetaEmpty | DbMetaMultipleRows | PoolMetadataHashMismatch @@ -42,9 +42,9 @@ instance ToJSON DBFail where [ "code" .= String "DbLookupBlockHash" , "description" .= String (renderLookupFail failure) ] - toJSON failure@(DbLookupTxMetadataHash _hash) = + toJSON failure@(DbLookupPoolMetadataHash _hash) = object - [ "code" .= String "DbLookupTxMetadataHash" + [ "code" .= String "DbLookupPoolMetadataHash" , "description" .= String (renderLookupFail failure) ] toJSON failure@DbMetaEmpty = @@ -83,7 +83,7 @@ renderLookupFail :: DBFail -> Text renderLookupFail lf = case lf of DbLookupBlockHash hash -> "The block hash " <> decodeUtf8 hash <> " is missing from the DB." - DbLookupTxMetadataHash hash -> "The tx hash " <> decodeUtf8 hash <> " is missing from the DB." + DbLookupPoolMetadataHash hash -> "The tx hash " <> decodeUtf8 hash <> " is missing from the DB."
