Bug 225855 – Avoid more String creations when preparing SQLite statements

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Chris Dumez]

Avoid more String creations when preparing SQLite statements by using ASCIILiteral. Also rename the SQLiteDatabase::prepareString(const String&) overload so that it doesn't get called by mistake.

We could use the preprocessor to put the common parts of this in one place.

It looks like this can be an ASCIILiteral too.

> +        "key TEXT NOT NULL ON CONFLICT FAIL UNIQUE ON CONFLICT REPLACE"

ditto on the duplicate code.  preprocessor

In Source/WebCore/ChangeLog?

Ditto.

static const String v3RecordsTableSchema(const String& tableName) is only used here with this change. Maybe just change it to static ASCIILiteral v3RecordsTableSchemaTemp()?

> Source/WebCore/Modules/indexeddb/server/SQLiteIDBBackingStore.cpp:455
> +    if (!m_sqliteDB->executeCommandSlow(v3IndexRecordsTableSchema("_Temp_IndexRecords"))) {

Same as above. Make it static ASCIILiteral v3IndexRecordsTableSchemaTemp()?

> Source/WebCore/Modules/indexeddb/server/SQLiteIDBBackingStore.cpp:596
> +    if (!m_sqliteDB->executeCommandSlow(indexInfoTableSchema("IndexInfo"_s))) {

Maybe convert static String indexInfoTableSchema(ASCIILiteral tableName) to static ASCIILiteral indexInfoTableSchema() and static ASCIILiteral indexInfoTableSchemaTemp()?

> Source/WebCore/Modules/indexeddb/server/SQLiteIDBBackingStore.cpp:783
> +    if (!database.executeCommandSlow(v3IndexRecordsTableSchema("_Temp_IndexRecords"))) {

static ASCIILiteral v3IndexRecordsTableSchemaTemp()?
