** **
** These routines all implement some additional formatting ** See also: [built-in printf()], [printf() SQL function]
** options that are useful for constructing SQL statements.
** All of the usual printf() formatting options apply. In addition, there
** is are "%q", "%Q", "%w" and "%z" options.
**
** ^(The %q option works like %s in that it substitutes a nul-terminated
** string from the argument list. But %q also doubles every '\'' character.
** %q is designed for use inside a string literal.)^ By doubling each '\''
** character it escapes that character and allows it to be inserted into
** the string.
**
** For example, assume the string variable zText contains text as follows:
**
** <blockquote><pre>
** char *zText = "It's a happy day!";
** </pre></blockquote>
**
** One can use this text in an SQL statement as follows:
**
** <blockquote><pre>
** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
** sqlite3_exec(db, zSQL, 0, 0, 0);
** sqlite3_free(zSQL);
** </pre></blockquote>
**
** Because the %q format string is used, the '\'' character in zText
** is escaped and the SQL generated is as follows:
**
** <blockquote><pre>
** INSERT INTO table1 VALUES('It''s a happy day!')
** </pre></blockquote>
**
** This is correct. Had we used %s instead of %q, the generated SQL
** would have looked like this:
**
** <blockquote><pre>
** INSERT INTO table1 VALUES('It's a happy day!');
** </pre></blockquote>
**
** This second example is an SQL syntax error. As a general rule you should
** always use %q instead of %s when inserting text into a string literal.
**
** ^(The %Q option works like %q except it also adds single quotes around
** the outside of the total string. Additionally, if the parameter in the
** argument list is a NULL pointer, %Q substitutes the text "NULL" (without
** single quotes).)^ So, for example, one could say:
**
** <blockquote><pre>
** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
** sqlite3_exec(db, zSQL, 0, 0, 0);
** sqlite3_free(zSQL);
** </pre></blockquote>
**
** The code above will render a correct SQL statement in the zSQL
** variable even if the zText variable is a NULL pointer.
**
** ^(The "%w" formatting option is like "%q" except that it expects to
** be contained within double-quotes instead of single quotes, and it
** escapes the double-quote character instead of the single-quote
** character.)^ The "%w" formatting option is intended for safely inserting
** table and column names into a constructed SQL statement.
**
** ^(The "%z" formatting option works like "%s" but with the
** addition that after the string has been read and copied into
** the result, [sqlite3_free()] is called on the input string.)^

** CAPI3REF: Serialize a database
**
** The sqlite3_serialize(D,S,P,F) interface returns a pointer to memory
** that is a serialization of the S database on [database connection] D.
** If P is not a NULL pointer, then the size of the database in bytes
** is written into *P.
**
** For an ordinary on-disk database file, the serialization is just a
** copy of the disk file. For an in-memory database or a "TEMP" database,
** the serialization is the same sequence of bytes which would be written
** to disk if that database where backed up to disk.
**
** The usual case is that sqlite3_serialize() copies the serialization of
** the database into memory obtained from [sqlite3_malloc64()] and returns
** a pointer to that memory. The caller is responsible for freeing the
** returned value to avoid a memory leak. However, if the F argument
** contains the SQLITE_SERIALIZE_NOCOPY bit, then no memory allocations
** are made, and the sqlite3_serialize() function will return a pointer
** to the contiguous memory representation of the database that SQLite
** is currently using for that database, or NULL if the no such contiguous
** memory representation of the database exists. A contiguous memory
** representation of the database will usually only exist if there has
** been a prior call to [sqlite3_deserialize(D,S,...)] with the same
** values of D and S.
** The size of the database is written into *P even if the
** SQLITE_SERIALIZE_NOCOPY bit is set but no contigious copy
** of the database exists.
**
** A call to sqlite3_serialize(D,S,P,F) might return NULL even if the
** SQLITE_SERIALIZE_NOCOPY bit is omitted from argument F if a memory
** allocation error occurs.
**
** This interface is only available if SQLite is compiled with the
** [SQLITE_ENABLE_DESERIALIZE] option.

** in P. The serialized database P is N bytes in size. M is the size of

** CAPI3REF: Rebasing changesets
** EXPERIMENTAL
**
** Suppose there is a site hosting a database in state S0. And that
** modifications are made that move that database to state S1 and a
** changeset recorded (the "local" changeset). Then, a changeset based
** on S0 is received from another site (the "remote" changeset) and
** applied to the database. The database is then in state
** (S1+"remote"), where the exact state depends on any conflict
** resolution decisions (OMIT or REPLACE) made while applying "remote".
** Rebasing a changeset is to update it to take those conflict
** resolution decisions into account, so that the same conflicts
** do not have to be resolved elsewhere in the network.
**
** For example, if both the local and remote changesets contain an
** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
**
** local: INSERT INTO t1 VALUES(1, 'v1');
** remote: INSERT INTO t1 VALUES(1, 'v2');
**
** and the conflict resolution is REPLACE, then the INSERT change is
** removed from the local changeset (it was overridden). Or, if the
** conflict resolution was "OMIT", then the local changeset is modified
** to instead contain:
**
** UPDATE t1 SET b = 'v2' WHERE a=1;
**
** Changes within the local changeset are rebased as follows:
**
** <dl>
** <dt>Local INSERT<dd>
** This may only conflict with a remote INSERT. If the conflict
** resolution was OMIT, then add an UPDATE change to the rebased
** changeset. Or, if the conflict resolution was REPLACE, add
** nothing to the rebased changeset.
**
** <dt>Local DELETE<dd>
** This may conflict with a remote UPDATE or DELETE. In both cases the
** only possible resolution is OMIT. If the remote operation was a
** DELETE, then add no change to the rebased changeset. If the remote
** operation was an UPDATE, then the old.* fields of change are updated
** to reflect the new.* values in the UPDATE.
**
** <dt>Local UPDATE<dd>
** This may conflict with a remote UPDATE or DELETE. If it conflicts
** with a DELETE, and the conflict resolution was OMIT, then the update
** is changed into an INSERT. Any undefined values in the new.* record
** from the update change are filled in using the old.* values from
** the conflicting DELETE. Or, if the conflict resolution was REPLACE,
** the UPDATE change is simply omitted from the rebased changeset.
**
** If conflict is with a remote UPDATE and the resolution is OMIT, then
** the old.* values are rebased using the new.* values in the remote
** change. Or, if the resolution is REPLACE, then the change is copied
** into the rebased changeset with updates to columns also updated by
** the conflicting remote UPDATE removed. If this means no columns would
** be updated, the change is omitted.
** </dl>
**
** A local change may be rebased against multiple remote changes
** simultaneously. If a single key is modified by multiple remote
** changesets, they are combined as follows before the local changeset
** is rebased:
**
** <ul>
** <li> If there has been one or more REPLACE resolutions on a
** key, it is rebased according to a REPLACE.
**
** <li> If there have been no REPLACE resolutions on a key, then
** the local changeset is rebased according to the most recent
** of the OMIT resolutions.
** </ul>
**
** Note that conflict resolutions from multiple remote changesets are
** combined on a per-field basis, not per-row. This means that in the
** case of multiple remote UPDATE operations, some fields of a single
** local change may be rebased for REPLACE while others are rebased for
** OMIT.
**
** In order to rebase a local changeset, the remote changeset must first
** be applied to the local database using sqlite3changeset_apply_v2() and
** the buffer of rebase information captured. Then:
**
** <ol>
** <li> An sqlite3_rebaser object is created by calling
** sqlite3rebaser_create().
** <li> The new object is configured with the rebase buffer obtained from
** sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
** If the local changeset is to be rebased against multiple remote
** changesets, then sqlite3rebaser_configure() should be called
** multiple times, in the same order that the multiple
** sqlite3changeset_apply_v2() calls were made.
** <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().
** <li> The sqlite3_rebaser object is deleted by calling
** sqlite3rebaser_delete().
