-Polymer is based on a set of future technologies, including [Shadow DOM](https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html), [Custom Elements](https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/custom/index.html) and Model Driven Views. Currently these technologies are implemented as polyfills or shims, but as browsers adopt these features natively, the platform code that drives Polymer evacipates, leaving only the value-adds.

-/* TODO(shess): THIS MODULE IS STILL EXPERIMENTAL.  DO NOT USE IT. */
-/* Implements a virtual table "recover" which can be used to recover
- * data from a corrupt table.  The table is walked manually, with
- * corrupt items skipped.  Additionally, any errors while reading will
- * be skipped.
- *
- * Given a table with this definition:
- *
- * CREATE TABLE Stuff (
- *   name TEXT PRIMARY KEY,
- *   value TEXT NOT NULL
- * );
- *
- * to recover the data from teh table, you could do something like:
- *
- * -- Attach another database, the original is not trustworthy.
- * ATTACH DATABASE '/tmp/db.db' AS rdb;
- * -- Create a new version of the table.
- * CREATE TABLE rdb.Stuff (
- *   name TEXT PRIMARY KEY,
- *   value TEXT NOT NULL
- * );
- * -- This will read the original table's data.
- * CREATE VIRTUAL TABLE temp.recover_Stuff using recover(
- *   main.Stuff,
- *   name TEXT STRICT NOT NULL,  -- only real TEXT data allowed
- *   value TEXT STRICT NOT NULL
- * );
- * -- Corruption means the UNIQUE constraint may no longer hold for
- * -- Stuff, so either OR REPLACE or OR IGNORE must be used.
- * INSERT OR REPLACE INTO rdb.Stuff (rowid, name, value )
- *   SELECT rowid, name, value FROM temp.recover_Stuff;
- * DROP TABLE temp.recover_Stuff;
- * DETACH DATABASE rdb;
- * -- Move db.db to replace original db in filesystem.
- *
- *
- * Usage
- *
- * Given the goal of dealing with corruption, it would not be safe to
- * create a recovery table in the database being recovered.  So
- * recovery tables must be created in the temp database.  They are not
- * appropriate to persist, in any case.  [As a bonus, sqlite_master
- * tables can be recovered.  Perhaps more cute than useful, though.]
- *
- * The parameters are a specifier for the table to read, and a column
- * definition for each bit of data stored in that table.  The named
- * table must be convertable to a root page number by reading the
- * sqlite_master table.  Bare table names are assumed to be in
- * database 0 ("main"), other databases can be specified in db.table
- * fashion.
- *
- * Column definitions are similar to BUT NOT THE SAME AS those
- * provided to CREATE statements:
- *  column-def: column-name [type-name [STRICT] [NOT NULL]]
- *  type-name: (ANY|ROWID|INTEGER|FLOAT|NUMERIC|TEXT|BLOB)
- *
- * Only those exact type names are accepted, there is no type
- * intuition.  The only constraints accepted are STRICT (see below)
- * and NOT NULL.  Anything unexpected will cause the create to fail.
- *
- * ANY is a convenience to indicate that manifest typing is desired.
- * It is equivalent to not specifying a type at all.  The results for
- * such columns will have the type of the data's storage.  The exposed
- * schema will contain no type for that column.
- *
- * ROWID is used for columns representing aliases to the rowid
- * (INTEGER PRIMARY KEY, with or without AUTOINCREMENT), to make the
- * concept explicit.  Such columns are actually stored as NULL, so
- * they cannot be simply ignored.  The exposed schema will be INTEGER
- * for that column.
- *
- * NOT NULL causes rows with a NULL in that column to be skipped.  It
- * also adds NOT NULL to the column in the exposed schema.  If the
- * table has ever had columns added using ALTER TABLE, then those
- * columns implicitly contain NULL for rows which have not been
- * updated.  [Workaround using COALESCE() in your SELECT statement.]
- *
- * The created table is read-only, with no indices.  Any SELECT will
- * be a full-table scan, returning each valid row read from the
- * storage of the backing table.  The rowid will be the rowid of the
- * row from the backing table.  "Valid" means:
- * - The cell metadata for the row is well-formed.  Mainly this means that
- *   the cell header info describes a payload of the size indicated by
- *   the cell's payload size.
- * - The cell does not run off the page.
- * - The cell does not overlap any other cell on the page.
- * - The cell contains doesn't contain too many columns.
- * - The types of the serialized data match the indicated types (see below).
- *
- *
- * Type affinity versus type storage.
- *
- * http://www.sqlite.org/datatype3.html describes SQLite's type
- * affinity system.  The system provides for automated coercion of
- * types in certain cases, transparently enough that many developers
- * do not realize that it is happening.  Importantly, it implies that
- * the raw data stored in the database may not have the obvious type.
- *
- * Differences between the stored data types and the expected data
- * types may be a signal of corruption.  This module makes some
- * allowances for automatic coercion.  It is important to be concious
- * of the difference between the schema exposed by the module, and the
- * data types read from storage.  The following table describes how
- * the module interprets things:
- *
- * type     schema   data                     STRICT
- * ----     ------   ----                     ------
- * ANY      <none>   any                      any
- * ROWID    INTEGER  n/a                      n/a
- * INTEGER  INTEGER  integer                  integer
- * FLOAT    FLOAT    integer or float         float
- * NUMERIC  NUMERIC  integer, float, or text  integer or float
- * TEXT     TEXT     text or blob             text
- * BLOB     BLOB     blob                     blob
- *
- * type is the type provided to the recover module, schema is the
- * schema exposed by the module, data is the acceptable types of data
- * decoded from storage, and STRICT is a modification of that.
- *
- * A very loose recovery system might use ANY for all columns, then
- * use the appropriate sqlite3_column_*() calls to coerce to expected
- * types.  This doesn't provide much protection if a page from a
- * different table with the same column count is linked into an
- * inappropriate btree.
- *
- * A very tight recovery system might use STRICT to enforce typing on
- * all columns, preferring to skip rows which are valid at the storage
- * level but don't contain the right types.  Note that FLOAT STRICT is
- * almost certainly not appropriate, since integral values are
- * transparently stored as integers, when that is more efficient.
- *
- * Another option is to use ANY for all columns and inspect each
- * result manually (using sqlite3_column_*).  This should only be
- * necessary in cases where developers have used manifest typing (test
- * to make sure before you decide that you aren't using manifest
- * typing!).
- *
- *
- * Caveats
- *
- * Leaf pages not referenced by interior nodes will not be found.
- *
- * Leaf pages referenced from interior nodes of other tables will not
- * be resolved.
- *
- * Rows referencing invalid overflow pages will be skipped.
- *
- * SQlite rows have a header which describes how to interpret the rest
- * of the payload.  The header can be valid in cases where the rest of
- * the record is actually corrupt (in the sense that the data is not
- * the intended data).  This can especially happen WRT overflow pages,
- * as lack of atomic updates between pages is the primary form of
- * corruption I have seen in the wild.
- */
-/* TODO(shess): It might be useful to allow DEFAULT in types to
- * specify what to do for NULL when an ALTER TABLE case comes up.
- * Unfortunately, simply adding it to the exposed schema and using
- * sqlite3_result_null() does not cause the default to be generate.
- * Handling it ourselves seems hard, unfortunately.
