Both modules require that the +** "sqlite_dbpage" eponymous virtual table be available. +** +** SQLITE_DBDATA: +** sqlite_dbdata is used to extract data directly from a database b-tree +** page and its associated overflow pages, bypassing the b-tree layer. +** The table schema is equivalent to: +** +** CREATE TABLE sqlite_dbdata( +** pgno INTEGER, +** cell INTEGER, +** field INTEGER, +** value ANY, +** schema TEXT HIDDEN +** ); +** +** IMPORTANT: THE VIRTUAL TABLE SCHEMA ABOVE IS SUBJECT TO CHANGE. IN THE +** FUTURE NEW NON-HIDDEN COLUMNS MAY BE ADDED BETWEEN "value" AND +** "schema". +** +** Each page of the database is inspected. If it cannot be interpreted as +** a b-tree page, or if it is a b-tree page containing 0 entries, the +** sqlite_dbdata table contains no rows for that page. Otherwise, the +** table contains one row for each field in the record associated with +** each cell on the page. For intkey b-trees, the key value is stored in +** field -1. +** +** For example, for the database: +** +** CREATE TABLE t1(a, b); -- root page is page 2 +** INSERT INTO t1(rowid, a, b) VALUES(5, 'v', 'five'); +** INSERT INTO t1(rowid, a, b) VALUES(10, 'x', 'ten'); +** +** the sqlite_dbdata table contains, as well as from entries related to +** page 1, content equivalent to: +** +** INSERT INTO sqlite_dbdata(pgno, cell, field, value) VALUES +** (2, 0, -1, 5 ), +** (2, 0, 0, 'v' ), +** (2, 0, 1, 'five'), +** (2, 1, -1, 10 ), +** (2, 1, 0, 'x' ), +** (2, 1, 1, 'ten' ); +** +** If database corruption is encountered, this module does not report an +** error. Instead, it attempts to extract as much data as possible and +** ignores the corruption. +** +** SQLITE_DBPTR: +** The sqlite_dbptr table has the following schema: +** +** CREATE TABLE sqlite_dbptr( +** pgno INTEGER, +** child INTEGER, +** schema TEXT HIDDEN +** ); +** +** It contains one entry for each b-tree pointer between a parent and +** child page in the database. +*/ + +#pragma GCC diagnostic push +#pragma GCC diagnostic ignored "-Wimplicit-fallthrough" +#pragma GCC diagnostic ignored "-Wunused-parameter" +#if !defined(SQLITEINT_H) +#include "sqlite3.h" + +typedef unsigned char u8; +typedef unsigned int u32; + +#endif +#include <string.h> +#include <assert.h> + +#ifndef SQLITE_OMIT_VIRTUALTABLE + +#define DBDATA_PADDING_BYTES 100 + +typedef struct DbdataTable DbdataTable; +typedef struct DbdataCursor DbdataCursor; + +/* Cursor object */ +struct DbdataCursor { + sqlite3_vtab_cursor base; /* Base class.
