+ Usually 1024.
+
+Number of pages in the whole file
+}
+puts " The number of $pageSize-byte pages that go into forming the complete
+ database"
+puts {
+Pages that store data
+
+ The number of pages that store data, either as primary B*Tree pages or
+ as overflow pages. The number at the right is the data pages divided by
+ the total number of pages in the file.
+
+Pages on the freelist
+
+ The number of pages that are not currently in use but are reserved for
+ future use. The percentage at the right is the number of freelist pages
+ divided by the total number of pages in the file.
+
+Pages of auto-vacuum overhead
+
+ The number of pages that store data used by the database to facilitate
+ auto-vacuum. This is zero for databases that do not support auto-vacuum.
+
+Number of tables in the database
+
+ The number of tables in the database, including the SQLITE_MASTER table
+ used to store schema information.
+
+Number of indices
+
+ The total number of indices in the database.
+
+Number of defined indices
+
+ The number of indices created using an explicit CREATE INDEX statement.
+
+Number of implied indices
+
+ The number of indices used to implement PRIMARY KEY or UNIQUE constraints
+ on tables.
+
+Size of the file in bytes
+
+ The total amount of disk space used by the entire database files.
+
+Bytes of user payload stored
+
+ The total number of bytes of user payload stored in the database. The
+ schema information in the SQLITE_MASTER table is not counted when
+ computing this number. The percentage at the right shows the payload
+ divided by the total file size.
+
+Percentage of total database
+
+ The amount of the complete database file that is devoted to storing
+ information described by this category.
+
+Number of entries
+
+ The total number of B-Tree key/value pairs stored under this category.
+
+Bytes of storage consumed
+
+ The total amount of disk space required to store all B-Tree entries
+ under this category. The is the total number of pages used times
+ the pages size.
+
+Bytes of payload
+
+ The amount of payload stored under this category. Payload is the data
+ part of table entries and the key part of index entries. The percentage
+ at the right is the bytes of payload divided by the bytes of storage
+ consumed.
+
+Bytes of metadata
+
+ The amount of formatting and structural information stored in the
+ table or index. Metadata includes the btree page header, the cell pointer
+ array, the size field for each cell, the left child pointer or non-leaf
+ cells, the overflow pointers for overflow cells, and the rowid value for
+ rowid table cells. In other words, metadata is everything that is neither
+ unused space nor content. The record header in the payload is counted as
+ content, not metadata.
+
+Average payload per entry
+
+ The average amount of payload on each entry. This is just the bytes of
+ payload divided by the number of entries.
+
+Average unused bytes per entry
+
+ The average amount of free space remaining on all pages under this
+ category on a per-entry basis. This is the number of unused bytes on
+ all pages divided by the number of entries.
+
+Non-sequential pages
+
+ The number of pages in the table or index that are out of sequence.
+ Many filesystems are optimized for sequential file access so a small
+ number of non-sequential pages might result in faster queries,
+ especially for larger database files that do not fit in the disk cache.
+ Note that after running VACUUM, the root page of each table or index is
+ at the beginning of the database file and all other pages are in a
+ separate part of the database file, resulting in a single non-
+ sequential page.
+
+Maximum payload per entry
+
+ The largest payload size of any entry.
+
+Entries that use overflow
+
+ The number of entries that user one or more overflow pages.
+
+Total pages used
+
+ This is the number of pages used to hold all information in the current
+ category. This is the sum of index, primary, and overflow pages.
+
+Index pages used
+
+ This is the number of pages in a table B-tree that hold only key (rowid)
+ information and no data.
+
+Primary pages used
+
+ This is the number of B-tree pages that hold both key and data.
+
+Overflow pages used
+
+ The total number of overflow pages used for this category.
+
+Unused bytes on index pages
+
+ The total number of bytes of unused space on all index pages. The
+ percentage at the right is the number of unused bytes divided by the
+ total number of bytes on index pages.
+
+Unused bytes on primary pages
+
+ The total number of bytes of unused space on all primary pages. The
+ percentage at the right is the number of unused bytes divided by the
+ total number of bytes on primary pages.
+
+Unused bytes on overflow pages
+
+ The total number of bytes of unused space on all overflow pages. The
+ percentage at the right is the number of unused bytes divided by the
+ total number of bytes on overflow pages.
+

+*************************************************************************
+**
+** This file contains code for a demonstration virtual table that finds
+** "approximate matches" - strings from a finite set that are nearly the
+** same as a single input string. The virtual table is called "amatch".
+**
+** A amatch virtual table is created like this:
+**
+** CREATE VIRTUAL TABLE f USING approximate_match(
+** vocabulary_table=<tablename>, -- V
+** vocabulary_word=<columnname>, -- W
+** vocabulary_language=<columnname>, -- L
+** edit_distances=<edit-cost-table>
+** );
+**
+** When it is created, the new amatch table must be supplied with the
+** the name of a table V and columns V.W and V.L such that
+**
+** SELECT W FROM V WHERE L=$language
+**
+** returns the allowed vocabulary for the match. If the "vocabulary_language"
+** or L columnname is left unspecified or is an empty string, then no
+** filtering of the vocabulary by language is performed.
+**
+** For efficiency, it is essential that the vocabulary table be indexed:
+**
+** CREATE vocab_index ON V(W)
+**
+** A separate edit-cost-table provides scoring information that defines
+** what it means for one string to be "close" to another.
+**
+** The edit-cost-table must contain exactly four columns (more precisely,
+** the statement "SELECT * FROM <edit-cost-table>" must return records
+** that consist of four columns). It does not matter what the columns are
+** named.
+**
+** Each row in the edit-cost-table represents a single character
+** transformation going from user input to the vocabulary. The leftmost
+** column of the row (column 0) contains an integer identifier of the
+** language to which the transformation rule belongs (see "MULTIPLE LANGUAGES"
+** below). The second column of the row (column 1) contains the input
+** character or characters - the characters of user input. The third
+** column contains characters as they appear in the vocabulary table.
+** And the fourth column contains the integer cost of making the
+** transformation. For example:
+**
+** CREATE TABLE f_data(iLang, cFrom, cTo, Cost);
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '', 'a', 100);
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, 'b', '', 87);
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, 'o', 'oe', 38);
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, 'oe', 'o', 40);
+**
+** The first row inserted into the edit-cost-table by the SQL script
+** above indicates that the cost of having an extra 'a' in the vocabulary
+** table that is missing in the user input 100. (All costs are integers.
+** Overall cost must not exceed 16777216.) The second INSERT statement
+** creates a rule saying that the cost of having a single letter 'b' in
+** user input which is missing in the vocabulary table is 87. The third
+** INSERT statement mean that the cost of matching an 'o' in user input
+** against an 'oe' in the vocabulary table is 38. And so forth.
+**
+** The following rules are special:
+**
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '?', '', 97);
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '', '?', 98);
+** INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '?', '?', 99);
+**
+** The '?' to '' rule is the cost of having any single character in the input
+** that is not found in the vocabular. The '' to '?' rule is the cost of
+** having a character in the vocabulary table that is missing from input.
+** And the '?' to '?' rule is the cost of doing an arbitrary character
+** substitution. These three generic rules apply across all languages.
+** In other words, the iLang field is ignored for the generic substitution
+** rules. If more than one cost is given for a generic substitution rule,
+** then the lowest cost is used.
+**
+** Once it has been created, the amatch virtual table can be queried
+** as follows:
+**
+** SELECT word, distance FROM f
+** WHERE word MATCH 'abcdefg'
+** AND distance<200;
+**
+** This query outputs the strings contained in the T(F) field that
+** are close to "abcdefg" and in order of increasing distance. No string
+** is output more than once. If there are multiple ways to transform the
+** target string ("abcdefg") into a string in the vocabulary table then
+** the lowest cost transform is the one that is returned. In this example,
+** the search is limited to strings with a total distance of less than 200.
+**
+** For efficiency, it is important to put tight bounds on the distance.
+** The time and memory space needed to perform this query is exponential
+** in the maximum distance. A good rule of thumb is to limit the distance
+** to no more than 1.5 or 2 times the maximum cost of any rule in the
+** edit-cost-table.
+**
+** The amatch is a read-only table. Any attempt to DELETE, INSERT, or
+** UPDATE on a amatch table will throw an error.
+**
+** It is important to put some kind of a limit on the amatch output. This
+** can be either in the form of a LIMIT clause at the end of the query,
+** or better, a "distance<NNN" constraint where NNN is some number. The
+** running time and memory requirement is exponential in the value of NNN
+** so you want to make sure that NNN is not too big. A value of NNN that
+** is about twice the average transformation cost seems to give good results.
+**
+** The amatch table can be useful for tasks such as spelling correction.
+** Suppose all allowed words are in table vocabulary(w). Then one would create
+** an amatch virtual table like this:
+**
+** CREATE VIRTUAL TABLE ex1 USING amatch(
+** vocabtable=vocabulary,
+** vocabcolumn=w,
+** edit_distances=ec1
+** );
+**
+** Then given an input word $word, look up close spellings this way:
+**
+** SELECT word, distance FROM ex1
+** WHERE word MATCH $word AND distance<200;
+**
+** MULTIPLE LANGUAGES
+**
+** Normally, the "iLang" value associated with all character transformations
+** in the edit-cost-table is zero. However, if required, the amatch
+** virtual table allows multiple languages to be defined. Each query uses
+** only a single iLang value. This allows, for example, a single
+** amatch table to support multiple languages.
+**
+** By default, only the rules with iLang=0 are used. To specify an
+** alternative language, a "language = ?" expression must be added to the
+** WHERE clause of a SELECT, where ? is the integer identifier of the desired
+** language. For example:
+**
+** SELECT word, distance FROM ex1
+** WHERE word MATCH $word
+** AND distance<=200
+** AND language=1 -- Specify use language 1 instead of 0
+**
+** If no "language = ?" constraint is specified in the WHERE clause, language
+** 0 is used.
+**
+** LIMITS
+**
+** The maximum language number is 2147483647. The maximum length of either
+** of the strings in the second or third column of the amatch data table
+** is 50 bytes. The maximum cost on a rule is 1000.

+******************************************************************************
+**
+** This file implements a VFS shim that allows an SQLite database to be
+** appended onto the end of some other file, such as an executable.
+**
+** A special record must appear at the end of the file that identifies the
+** file as an appended database and provides an offset to page 1. For
+** best performance page 1 should be located at a disk page boundary, though
+** that is not required.
+**
+** When opening a database using this VFS, the connection might treat
+** the file as an ordinary SQLite database, or it might treat is as a
+** database appended onto some other file. Here are the rules:
+**
+** (1) When opening a new empty file, that file is treated as an ordinary
+** database.
+**
+** (2) When opening a file that begins with the standard SQLite prefix
+** string "SQLite format 3", that file is treated as an ordinary
+** database.
+**
+** (3) When opening a file that ends with the appendvfs trailer string
+** "Start-Of-SQLite3-NNNNNNNN" that file is treated as an appended
+** database.
+**
+** (4) If none of the above apply and the SQLITE_OPEN_CREATE flag is
+** set, then a new database is appended to the already existing file.
+**
+** (5) Otherwise, SQLITE_CANTOPEN is returned.
+**
+** To avoid unnecessary complications with the PENDING_BYTE, the size of
+** the file containing the database is limited to 1GB. This VFS will refuse
+** to read or write past the 1GB mark. This restriction might be lifted in
+** future versions. For now, if you need a large database, then keep the
+** database in a separate file.
+**
+** If the file being opened is not an appended database, then this shim is
+** a pass-through into the default underlying VFS.

+******************************************************************************
+**
+** This file contains an implementation of the "sqlite_btreeinfo" virtual table.
+**
+** The sqlite_btreeinfo virtual table is a read-only eponymous-only virtual
+** table that shows information about all btrees in an SQLite database file.
+** The schema is like this:
+**
+** CREATE TABLE sqlite_btreeinfo(
+** type TEXT, -- "table" or "index"
+** name TEXT, -- Name of table or index for this btree.
+** tbl_name TEXT, -- Associated table
+** rootpage INT, -- The root page of the btree
+** sql TEXT, -- SQL for this btree - from sqlite_master
+** hasRowid BOOLEAN, -- True if the btree has a rowid
+** nEntry INT, -- Estimated number of enteries
+** nPage INT, -- Estimated number of pages
+** depth INT, -- Depth of the btree
+** szPage INT, -- Size of each page in bytes
+** zSchema TEXT HIDDEN -- The schema to which this btree belongs
+** );
+**
+** The first 5 fields are taken directly from the sqlite_master table.
+** Considering only the first 5 fields, the only difference between
+** this virtual table and the sqlite_master table is that this virtual
+** table omits all entries that have a 0 or NULL rowid - in other words
+** it omits triggers and views.
+**
+** The value added by this table comes in the next 5 fields.
+**
+** Note that nEntry and nPage are *estimated*. They are computed doing
+** a single search from the root to a leaf, counting the number of cells
+** at each level, and assuming that unvisited pages have a similar number
+** of cells.
+**
+** The sqlite_dbpage virtual table must be available for this virtual table
+** to operate.
+**
+** USAGE EXAMPLES:
+**
+** Show the table btrees in a schema order with the tables with the most
+** rows occuring first:
+**
+** SELECT name, nEntry
+** FROM sqlite_btreeinfo
+** WHERE type='table'
+** ORDER BY nEntry DESC, name;
+**
+** Show the names of all WITHOUT ROWID tables:
+**
+** SELECT name FROM sqlite_btreeinfo
+** WHERE type='table' AND NOT hasRowid;

+*************************************************************************
+**
+** This file demonstrates how to create a table-valued-function that
+** returns the values in a C-language array.
+** Examples:
+**
+** SELECT * FROM carray($ptr,5)
+**
+** The query above returns 5 integers contained in a C-language array
+** at the address $ptr. $ptr is a pointer to the array of integers.
+** The pointer value must be assigned to $ptr using the
+** sqlite3_bind_pointer() interface with a pointer type of "carray".
+** For example:
+**
+** static int aX[] = { 53, 9, 17, 2231, 4, 99 };
+** int i = sqlite3_bind_parameter_index(pStmt, "$ptr");
+** sqlite3_bind_pointer(pStmt, i, aX, "carray", 0);
+**
+** There is an optional third parameter to determine the datatype of
+** the C-language array. Allowed values of the third parameter are
+** 'int32', 'int64', 'double', 'char*'. Example:
+**
+** SELECT * FROM carray($ptr,10,'char*');
+**
+** The default value of the third parameter is 'int32'.
+**
+** HOW IT WORKS
+**
+** The carray "function" is really a virtual table with the
+** following schema:
+**
+** CREATE TABLE carray(
+** value,
+** pointer HIDDEN,
+** count HIDDEN,
+** ctype TEXT HIDDEN
+** );
+**
+** If the hidden columns "pointer" and "count" are unconstrained, then
+** the virtual table has no rows. Otherwise, the virtual table interprets
+** the integer value of "pointer" as a pointer to the array and "count"
+** as the number of elements in the array. The virtual table steps through
+** the array, element by element.

+*************************************************************************
+**
+** This file contains code for a virtual table that finds the transitive
+** closure of a parent/child relationship in a real table. The virtual
+** table is called "transitive_closure".
+**
+** A transitive_closure virtual table is created like this:
+**
+** CREATE VIRTUAL TABLE x USING transitive_closure(
+** tablename=<tablename>, -- T
+** idcolumn=<columnname>, -- X
+** parentcolumn=<columnname> -- P
+** );
+**
+** When it is created, the new transitive_closure table may be supplied
+** with default values for the name of a table T and columns T.X and T.P.
+** The T.X and T.P columns must contain integers. The ideal case is for
+** T.X to be the INTEGER PRIMARY KEY. The T.P column should reference
+** the T.X column. The row referenced by T.P is the parent of the current row.
+**
+** The tablename, idcolumn, and parentcolumn supplied by the CREATE VIRTUAL
+** TABLE statement may be overridden in individual queries by including
+** terms like tablename='newtable', idcolumn='id2', or
+** parentcolumn='parent3' in the WHERE clause of the query.
+**
+** For efficiency, it is essential that there be an index on the P column:
+**
+** CREATE Tidx1 ON T(P)
+**
+** Suppose a specific instance of the closure table is as follows:
+**
+** CREATE VIRTUAL TABLE ct1 USING transitive_closure(
+** tablename='group',
+** idcolumn='groupId',
+** parentcolumn='parentId'
+** );
+**
+** Such an instance of the transitive_closure virtual table would be
+** appropriate for walking a tree defined using a table like this, for example:
+**
+** CREATE TABLE group(
+** groupId INTEGER PRIMARY KEY,
+** parentId INTEGER REFERENCES group
+** );
+** CREATE INDEX group_idx1 ON group(parentId);
+**
+** The group table above would presumably have other application-specific
+** fields. The key point here is that rows of the group table form a
+** tree. The purpose of the ct1 virtual table is to easily extract
+** branches of that tree.
+**
+** Once it has been created, the ct1 virtual table can be queried
+** as follows:
+**
+** SELECT * FROM element
+** WHERE element.groupId IN (SELECT id FROM ct1 WHERE root=?1);
+**
+** The above query will return all elements that are part of group ?1
+** or children of group ?1 or grand-children of ?1 and so forth for all
+** descendents of group ?1. The same query can be formulated as a join:
+**
+** SELECT element.* FROM element, ct1
+** WHERE element.groupid=ct1.id
+** AND ct1.root=?1;
+**
+** The depth of the transitive_closure (the number of generations of
+** parent/child relations to follow) can be limited by setting "depth"
+** column in the WHERE clause. So, for example, the following query
+** finds only children and grandchildren but no further descendents:
+**
+** SELECT element.* FROM element, ct1
+** WHERE element.groupid=ct1.id
+** AND ct1.root=?1
+** AND ct1.depth<=2;
+**
+** The "ct1.depth<=2" term could be a strict equality "ct1.depth=2" in
+** order to find only the grandchildren of ?1, not ?1 itself or the
+** children of ?1.
+**
+** The root=?1 term must be supplied in WHERE clause or else the query
+** of the ct1 virtual table will return an empty set. The tablename,
+** idcolumn, and parentcolumn attributes can be overridden in the WHERE
+** clause if desired. So, for example, the ct1 table could be repurposed
+** to find ancestors rather than descendents by inverting the roles of
+** the idcolumn and parentcolumn:
+**
+** SELECT element.* FROM element, ct1
+** WHERE element.groupid=ct1.id
+** AND ct1.root=?1
+** AND ct1.idcolumn='parentId'
+** AND ct1.parentcolumn='groupId';
+**
+** Multiple calls to ct1 could be combined. For example, the following
+** query finds all elements that "cousins" of groupId ?1. That is to say
+** elements where the groupId is a grandchild of the grandparent of ?1.
+** (This definition of "cousins" also includes siblings and self.)
+**
+** SELECT element.* FROM element, ct1
+** WHERE element.groupId=ct1.id
+** AND ct1.depth=2
+** AND ct1.root IN (SELECT id FROM ct1
+** WHERE root=?1
+** AND depth=2
+** AND idcolumn='parentId'
+** AND parentcolumn='groupId');
+**
+** In our example, the group.groupId column is unique and thus the
+** subquery will return exactly one row. For that reason, the IN
+** operator could be replaced by "=" to get the same result. But
+** in the general case where the idcolumn is not unique, an IN operator
+** would be required for this kind of query.
+**
+** Note that because the tablename, idcolumn, and parentcolumn can
+** all be specified in the query, it is possible for an application
+** to define a single transitive_closure virtual table for use on lots
+** of different hierarchy tables. One might say:
+**
+** CREATE VIRTUAL TABLE temp.closure USING transitive_closure;
+**
+** As each database connection is being opened. Then the application
+** would always have a "closure" virtual table handy to use for querying.
+**
+** SELECT element.* FROM element, closure
+** WHERE element.groupid=ct1.id
+** AND closure.root=?1
+** AND closure.tablename='group'
+** AND closure.idname='groupId'
+** AND closure.parentname='parentId';
+**
+** See the documentation at http://www.sqlite.org/loadext.html for information
+** on how to compile and use loadable extensions such as this one.

+** This file implements an eponymous virtual table that returns suggested

+**
+** Suggested usage:

+** SELECT DISTINCT candidate COLLATE nocase

+** ORDER BY 1;
+**
+** The two query parameters are optional. $prefix is the text of the
+** current word being typed and that is to be completed. $wholeline is
+** the complete input line, used for context.
+**
+** The raw completion() table might return the same candidate multiple
+** times, for example if the same column name is used to two or more
+** tables. And the candidates are returned in an arbitrary order. Hence,
+** the DISTINCT and ORDER BY are recommended.
+**
+** This virtual table operates at the speed of human typing, and so there
+** is no attempt to make it fast. Even a slow implementation will be much
+** faster than any human can type.

+******************************************************************************
+**
+** This file contains the implementation of an SQLite virtual table for
+** reading CSV files.
+**
+** Usage:
+**
+** .load ./csv
+** CREATE VIRTUAL TABLE temp.csv USING csv(filename=FILENAME);
+** SELECT * FROM csv;
+**
+** The columns are named "c1", "c2", "c3", ... by default. Or the
+** application can define its own CREATE TABLE statement using the
+** schema= parameter, like this:
+**
+** CREATE VIRTUAL TABLE temp.csv2 USING csv(
+** filename = "../http.log",
+** schema = "CREATE TABLE x(date,ipaddr,url,referrer,userAgent)"
+** );
+**
+** Instead of specifying a file, the text of the CSV can be loaded using
+** the data= parameter.
+**
+** If the columns=N parameter is supplied, then the CSV file is assumed to have
+** N columns. If both the columns= and schema= parameters are omitted, then
+** the number and names of the columns is determined by the first line of
+** the CSV input.
+**
+** Some extra debugging features (used for testing virtual tables) are available
+** if this module is compiled with -DSQLITE_TEST.

+******************************************************************************
+**
+** This file contains an implementation of two eponymous virtual tables,
+** "sqlite_dbdata" and "sqlite_dbptr". 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.

+******************************************************************************
+**
+** This file implements a C-language subroutine that converts the content
+** of an SQLite database into UTF-8 text SQL statements that can be used
+** to exactly recreate the original database. ROWID values are preserved.
+**
+** A prototype of the implemented subroutine is this:
+**
+** int sqlite3_db_dump(
+** sqlite3 *db,
+** const char *zSchema,
+** const char *zTable,
+** void (*xCallback)(void*, const char*),
+** void *pArg
+** );
+**
+** The db parameter is the database connection. zSchema is the schema within
+** that database which is to be dumped. Usually the zSchema is "main" but
+** can also be "temp" or any ATTACH-ed database. If zTable is not NULL, then
+** only the content of that one table is dumped. If zTable is NULL, then all
+** tables are dumped.
+**
+** The generate text is passed to xCallback() in multiple calls. The second
+** argument to xCallback() is a copy of the pArg parameter. The first
+** argument is some of the output text that this routine generates. The
+** signature to xCallback() is designed to make it compatible with fputs().
+**
+** The sqlite3_db_dump() subroutine returns SQLITE_OK on success or some error
+** code if it encounters a problem.
+**
+** If this file is compiled with -DDBDUMP_STANDALONE then a "main()" routine
+** is included so that this routine becomes a command-line utility. The
+** command-line utility takes two or three arguments which are the name
+** of the database file, the schema, and optionally the table, forming the
+** first three arguments of a single call to the library routine.

+******************************************************************************
+**
+** This SQLite extension implements SQL functions readfile() and
+** writefile(), and eponymous virtual type "fsdir".
+**
+** WRITEFILE(FILE, DATA [, MODE [, MTIME]]):
+**
+** If neither of the optional arguments is present, then this UDF
+** function writes blob DATA to file FILE. If successful, the number
+** of bytes written is returned. If an error occurs, NULL is returned.
+**
+** If the first option argument - MODE - is present, then it must
+** be passed an integer value that corresponds to a POSIX mode
+** value (file type + permissions, as returned in the stat.st_mode
+** field by the stat() system call). Three types of files may
+** be written/created:
+**
+** regular files: (mode & 0170000)==0100000
+** symbolic links: (mode & 0170000)==0120000
+** directories: (mode & 0170000)==0040000
+**
+** For a directory, the DATA is ignored. For a symbolic link, it is
+** interpreted as text and used as the target of the link. For a
+** regular file, it is interpreted as a blob and written into the
+** named file. Regardless of the type of file, its permissions are
+** set to (mode & 0777) before returning.
+**
+** If the optional MTIME argument is present, then it is interpreted
+** as an integer - the number of seconds since the unix epoch. The
+** modification-time of the target file is set to this value before
+** returning.
+**
+** If three or more arguments are passed to this function and an
+** error is encountered, an exception is raised.
+**
+** READFILE(FILE):
+**
+** Read and return the contents of file FILE (type blob) from disk.
+**
+** FSDIR:
+**
+** Used as follows:
+**
+** SELECT * FROM fsdir($path [, $dir]);
+**
+** Parameter $path is an absolute or relative pathname. If the file that it
+** refers to does not exist, it is an error. If the path refers to a regular
+** file or symbolic link, it returns a single row. Or, if the path refers
+** to a directory, it returns one row for the directory, and one row for each
+** file within the hierarchy rooted at $path.
+**
+** Each row has the following columns:
+**
+** name: Path to file or directory (text value).
+** mode: Value of stat.st_mode for directory entry (an integer).
+** mtime: Value of stat.st_mtime for directory entry (an integer).
+** data: For a regular file, a blob containing the file data. For a
+** symlink, a text value containing the text of the link. For a
+** directory, NULL.
+**
+** If a non-NULL value is specified for the optional $dir parameter and
+** $path is a relative path, then $path is interpreted relative to $dir.
+** And the paths returned in the "name" column of the table are also
+** relative to directory $dir.

+** This SQLite extension implements the delta functions used by the RBU

+** delta_apply(X,D) -- apply delta D to file X and return the result
+** delta_create(X,Y) -- compute and return a delta that carries X into Y
+** delta_output_size(D) -- blob size in bytes output from applying delta D
+** delta_parse(D) -- returns rows describing delta D
+**
+** The delta format is the Fossil delta format, described in a comment

+**
+** https://www.fossil-scm.org/fossil/doc/trunk/www/delta_format.wiki
+**
+** This delta format is used by the RBU extension, which is the main

+** Create a new delta.
+**
+** The delta is written into a preallocated buffer, zDelta, which
+** should be at least 60 bytes longer than the target file, zOut.
+** The delta string will be NUL-terminated, but it might also contain
+** embedded NUL characters if either the zSrc or zOut files are
+** binary. This function returns the length of the delta string
+** in bytes, excluding the final NUL terminator character.
+**
+** Output Format:
+**
+** The delta begins with a base64 number followed by a newline. This
+** number is the number of bytes in the TARGET file. Thus, given a
+** delta file z, a program can compute the size of the output file
+** simply by reading the first line and decoding the base-64 number
+** found there. The delta_output_size() routine does exactly this.
+**
+** After the initial size number, the delta consists of a series of
+** literal text segments and commands to copy from the SOURCE file.
+** A copy command looks like this:
+**
+** NNN@MMM,
+**
+** where NNN is the number of bytes to be copied and MMM is the offset
+** into the source file of the first byte (both base-64). If NNN is 0
+** it means copy the rest of the input file. Literal text is like this:
+**
+** NNN:TTTTT
+**
+** where NNN is the number of bytes of text (base-64) and TTTTT is the text.
+**
+** The last term is of the form
+**
+** NNN;
+**
+** In this case, NNN is a 32-bit bigendian checksum of the output file
+** that can be used to verify that the delta applied correctly. All
+** numbers are in base-64.
+**
+** Pure text files generate a pure text delta. Binary files generate a
+** delta that may contain some binary data.
+**
+** Algorithm:
+**
+** The encoder first builds a hash table to help it find matching
+** patterns in the source file. 16-byte chunks of the source file
+** sampled at evenly spaced intervals are used to populate the hash
+** table.
+**
+** Next we begin scanning the target file using a sliding 16-byte
+** window. The hash of the 16-byte window in the target is used to
+** search for a matching section in the source file. When a match
+** is found, a copy command is added to the delta. An effort is
+** made to extend the matching section to regions that come before
+** and after the 16-byte hash window. A copy command is only issued
+** if the result would use less space that just quoting the text
+** literally. Literal text is added to the delta for sections that
+** do not match or which can not be encoded efficiently using copy
+** commands.

+*************************************************************************
+**
+** Code for a demonstration virtual table that generates variations
+** on an input word at increasing edit distances from the original.
+**
+** A fuzzer virtual table is created like this:
+**
+** CREATE VIRTUAL TABLE f USING fuzzer(<fuzzer-data-table>);
+**
+** When it is created, the new fuzzer table must be supplied with the
+** name of a "fuzzer data table", which must reside in the same database
+** file as the new fuzzer table. The fuzzer data table contains the various
+** transformations and their costs that the fuzzer logic uses to generate
+** variations.
+**
+** The fuzzer data table must contain exactly four columns (more precisely,
+** the statement "SELECT * FROM <fuzzer_data_table>" must return records
+** that consist of four columns). It does not matter what the columns are
+** named.
+**
+** Each row in the fuzzer data table represents a single character
+** transformation. The left most column of the row (column 0) contains an
+** integer value - the identifier of the ruleset to which the transformation
+** rule belongs (see "MULTIPLE RULE SETS" below). The second column of the
+** row (column 0) contains the input character or characters. The third
+** column contains the output character or characters. And the fourth column
+** contains the integer cost of making the transformation. For example:
+**
+** CREATE TABLE f_data(ruleset, cFrom, cTo, Cost);
+** INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, '', 'a', 100);
+** INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, 'b', '', 87);
+** INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, 'o', 'oe', 38);
+** INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, 'oe', 'o', 40);
+**
+** The first row inserted into the fuzzer data table by the SQL script
+** above indicates that the cost of inserting a letter 'a' is 100. (All
+** costs are integers. We recommend that costs be scaled so that the
+** average cost is around 100.) The second INSERT statement creates a rule
+** saying that the cost of deleting a single letter 'b' is 87. The third
+** and fourth INSERT statements mean that the cost of transforming a
+** single letter "o" into the two-letter sequence "oe" is 38 and that the
+** cost of transforming "oe" back into "o" is 40.
+**
+** The contents of the fuzzer data table are loaded into main memory when
+** a fuzzer table is first created, and may be internally reloaded by the
+** system at any subsequent time. Therefore, the fuzzer data table should be
+** populated before the fuzzer table is created and not modified thereafter.
+** If you do need to modify the contents of the fuzzer data table, it is
+** recommended that the associated fuzzer table be dropped, the fuzzer data
+** table edited, and the fuzzer table recreated within a single transaction.
+** Alternatively, the fuzzer data table can be edited then the database
+** connection can be closed and reopened.
+**
+** Once it has been created, the fuzzer table can be queried as follows:
+**
+** SELECT word, distance FROM f
+** WHERE word MATCH 'abcdefg'
+** AND distance<200;
+**
+** This first query outputs the string "abcdefg" and all strings that
+** can be derived from that string by appling the specified transformations.
+** The strings are output together with their total transformation cost
+** (called "distance") and appear in order of increasing cost. No string
+** is output more than once. If there are multiple ways to transform the
+** target string into the output string then the lowest cost transform is
+** the one that is returned. In the example, the search is limited to
+** strings with a total distance of less than 200.
+**
+** The fuzzer is a read-only table. Any attempt to DELETE, INSERT, or
+** UPDATE on a fuzzer table will throw an error.
+**
+** It is important to put some kind of a limit on the fuzzer output. This
+** can be either in the form of a LIMIT clause at the end of the query,
+** or better, a "distance<NNN" constraint where NNN is some number. The
+** running time and memory requirement is exponential in the value of NNN
+** so you want to make sure that NNN is not too big. A value of NNN that
+** is about twice the average transformation cost seems to give good results.
+**
+** The fuzzer table can be useful for tasks such as spelling correction.
+** Suppose there is a second table vocabulary(w) where the w column contains
+** all correctly spelled words. Let $word be a word you want to look up.
+**
+** SELECT vocabulary.w FROM f, vocabulary
+** WHERE f.word MATCH $word
+** AND f.distance<=200
+** AND f.word=vocabulary.w
+** LIMIT 20
+**
+** The query above gives the 20 closest words to the $word being tested.
+** (Note that for good performance, the vocubulary.w column should be
+** indexed.)
+**
+** A similar query can be used to find all words in the dictionary that
+** begin with some prefix $prefix:
+**
+** SELECT vocabulary.w FROM f, vocabulary
+** WHERE f.word MATCH $prefix
+** AND f.distance<=200
+** AND vocabulary.w BETWEEN f.word AND (f.word || x'F7BFBFBF')
+** LIMIT 50
+**
+** This last query will show up to 50 words out of the vocabulary that
+** match or nearly match the $prefix.
+**
+** MULTIPLE RULE SETS
+**
+** Normally, the "ruleset" value associated with all character transformations
+** in the fuzzer data table is zero. However, if required, the fuzzer table
+** allows multiple rulesets to be defined. Each query uses only a single
+** ruleset. This allows, for example, a single fuzzer table to support
+** multiple languages.
+**
+** By default, only the rules from ruleset 0 are used. To specify an
+** alternative ruleset, a "ruleset = ?" expression must be added to the
+** WHERE clause of a SELECT, where ? is the identifier of the desired
+** ruleset. For example:
+**
+** SELECT vocabulary.w FROM f, vocabulary
+** WHERE f.word MATCH $word
+** AND f.distance<=200
+** AND f.word=vocabulary.w
+** AND f.ruleset=1 -- Specify the ruleset to use here
+** LIMIT 20
+**
+** If no "ruleset = ?" constraint is specified in the WHERE clause, ruleset
+** 0 is used.
+**
+** LIMITS
+**
+** The maximum ruleset number is 2147483647. The maximum length of either
+** of the strings in the second or third column of the fuzzer data table
+** is 50 bytes. The maximum cost on a rule is 1000.

+******************************************************************************
+**
+** This file contains code to implement the next_char(A,T,F,W,C) SQL function.
+**
+** The next_char(A,T,F,W,C) function finds all valid "next" characters for
+** string A given the vocabulary in T.F. If the W value exists and is a
+** non-empty string, then it is an SQL expression that limits the entries
+** in T.F that will be considered. If C exists and is a non-empty string,
+** then it is the name of the collating sequence to use for comparison. If
+**
+** Only the first three arguments are required. If the C parameter is
+** omitted or is NULL or is an empty string, then the default collating
+** sequence of T.F is used for comparision. If the W parameter is omitted
+** or is NULL or is an empty string, then no filtering of the output is
+** done.
+**
+** The T.F column should be indexed using collation C or else this routine
+** will be quite slow.
+**
+** For example, suppose an application has a dictionary like this:
+**
+** CREATE TABLE dictionary(word TEXT UNIQUE);
+**
+** Further suppose that for user keypad entry, it is desired to disable
+** (gray out) keys that are not valid as the next character. If the
+** the user has previously entered (say) 'cha' then to find all allowed
+** next characters (and thereby determine when keys should not be grayed
+** out) run the following query:
+**
+** SELECT next_char('cha','dictionary','word');
+**
+** IMPLEMENTATION NOTES:
+**
+** The next_char function is implemented using recursive SQL that makes
+** use of the table name and column name as part of a query. If either
+** the table name or column name are keywords or contain special characters,
+** then they should be escaped. For example:
+**
+** SELECT next_char('cha','[dictionary]','[word]');
+**
+** This also means that the table name can be a subquery:
+**
+** SELECT next_char('cha','(SELECT word AS w FROM dictionary)','w');

+******************************************************************************
+**
+** This file contains code to implement the sqlite3_normalize() function.
+**
+** char *sqlite3_normalize(const char *zSql);
+**
+** This function takes an SQL string as input and returns a "normalized"
+** version of that string in memory obtained from sqlite3_malloc64(). The
+** caller is responsible for ensuring that the returned memory is freed.
+**
+** If a memory allocation error occurs, this routine returns NULL.
+**
+** The normalization consists of the following transformations:
+**
+** (1) Convert every literal (string, blob literal, numeric constant,
+** or "NULL" constant) into a ?
+**
+** (2) Remove all superfluous whitespace, including comments. Change
+** all required whitespace to a single space character.
+**
+** (3) Lowercase all ASCII characters.
+**
+** (4) If an IN or NOT IN operator is followed by a list of 1 or more
+** values, convert that list into "(?,?,?)".
+**
+** The purpose of normalization is two-fold:
+**
+** (1) Sanitize queries by removing potentially private or sensitive
+** information contained in literals.
+**
+** (2) Identify structurally identical queries by comparing their
+** normalized forms.
+**
+** Command-Line Utility
+** --------------------
+**
+** This file also contains code for a command-line utility that converts
+** SQL queries in text files into their normalized forms. To build the
+** command-line program, compile this file with -DSQLITE_NORMALIZE_CLI
+** and link it against the SQLite library.

+******************************************************************************
+**
+** This file contains code to implement the percentile(Y,P) SQL function
+** as described below:
+**
+** (1) The percentile(Y,P) function is an aggregate function taking
+** exactly two arguments.
+**
+** (2) If the P argument to percentile(Y,P) is not the same for every
+** row in the aggregate then an error is thrown. The word "same"
+** in the previous sentence means that the value differ by less
+** than 0.001.
+**
+** (3) If the P argument to percentile(Y,P) evaluates to anything other
+** than a number in the range of 0.0 to 100.0 inclusive then an
+** error is thrown.
+**
+** (4) If any Y argument to percentile(Y,P) evaluates to a value that
+** is not NULL and is not numeric then an error is thrown.
+**
+** (5) If any Y argument to percentile(Y,P) evaluates to plus or minus
+** infinity then an error is thrown. (SQLite always interprets NaN
+** values as NULL.)
+**
+** (6) Both Y and P in percentile(Y,P) can be arbitrary expressions,
+** including CASE WHEN expressions.
+**
+** (7) The percentile(Y,P) aggregate is able to handle inputs of at least
+** one million (1,000,000) rows.
+**
+** (8) If there are no non-NULL values for Y, then percentile(Y,P)
+** returns NULL.
+**
+** (9) If there is exactly one non-NULL value for Y, the percentile(Y,P)
+** returns the one Y value.
+**
+** (10) If there N non-NULL values of Y where N is two or more and
+** the Y values are ordered from least to greatest and a graph is
+** drawn from 0 to N-1 such that the height of the graph at J is
+** the J-th Y value and such that straight lines are drawn between
+** adjacent Y values, then the percentile(Y,P) function returns
+** the height of the graph at P*(N-1)/100.
+**
+** (11) The percentile(Y,P) function always returns either a floating
+** point number or NULL.
+**
+** (12) The percentile(Y,P) is implemented as a single C99 source-code
+** file that compiles into a shared-library or DLL that can be loaded
+** into SQLite using the sqlite3_load_extension() interface.

+******************************************************************************
+**
+** The code in this file implements a compact but reasonably
+** efficient regular-expression matcher for posix extended regular
+** expressions against UTF8 text.
+**
+** This file is an SQLite extension. It registers a single function
+** named "regexp(A,B)" where A is the regular expression and B is the
+** string to be matched. By registering this function, SQLite will also
+** then implement the "B regexp A" operator. Note that with the function
+** the regular expression comes first, but with the operator it comes
+** second.
+**
+** The following regular expression syntax is supported:
+**
+** X* zero or more occurrences of X
+** X+ one or more occurrences of X
+** X? zero or one occurrences of X
+** X{p,q} between p and q occurrences of X
+** (X) match X
+** X|Y X or Y
+** ^X X occurring at the beginning of the string
+** X$ X occurring at the end of the string
+** . Match any single character
+** \c Character c where c is one of \{}()[]|*+?.
+** \c C-language escapes for c in afnrtv. ex: \t or \n
+** \uXXXX Where XXXX is exactly 4 hex digits, unicode value XXXX
+** \xXX Where XX is exactly 2 hex digits, unicode value XX
+** [abc] Any single character from the set abc
+** [^abc] Any single character not in the set abc
+** [a-z] Any single character in the range a-z
+** [^a-z] Any single character not in the range a-z
+** \b Word boundary
+** \w Word character. [A-Za-z0-9_]
+** \W Non-word character
+** \d Digit
+** \D Non-digit
+** \s Whitespace character
+** \S Non-whitespace character
+**
+** A nondeterministic finite automaton (NFA) is used for matching, so the
+** performance is bounded by O(N*M) where N is the size of the regular
+** expression and M is the size of the input string. The matcher never
+** exhibits exponential behavior. Note that the X{p,q} operator expands
+** to p copies of X following by q-p copies of X? and that the size of the
+** regular expression in the O(N*M) performance bound is computed after

+**
+** This implementation of the remember() function uses a "carray"

+******************************************************************************
+**
+** This file implements a utility function (and a utility program) that
+** makes a copy of an SQLite database while simultaneously zeroing out all
+** deleted content.
+**
+** Normally (when PRAGMA secure_delete=OFF, which is the default) when SQLite
+** deletes content, it does not overwrite the deleted content but rather marks
+** the region of the file that held that content as being reusable. This can
+** cause deleted content to recoverable from the database file. This stale
+** content is removed by the VACUUM command, but VACUUM can be expensive for
+** large databases. When in PRAGMA secure_delete=ON mode, the deleted content
+** is zeroed, but secure_delete=ON has overhead as well.
+**
+** This utility attempts to make a copy of a complete SQLite database where
+** all of the deleted content is zeroed out in the copy, and it attempts to
+** do so while being faster than running VACUUM.
+**
+** Usage:
+**
+** int sqlite3_scrub_backup(
+** const char *zSourceFile, // Source database filename
+** const char *zDestFile, // Destination database filename
+** char **pzErrMsg // Write error message here
+** );
+**
+** Simply call the API above specifying the filename of the source database
+** and the name of the backup copy. The source database must already exist
+** and can be in active use. (A read lock is held during the backup.) The
+** destination file should not previously exist. If the pzErrMsg parameter
+** is non-NULL and if an error occurs, then an error message might be written
+** into memory obtained from sqlite3_malloc() and *pzErrMsg made to point to
+** that error message. But if the error is an OOM, the error might not be
+** reported. The routine always returns non-zero if there is an error.
+**
+** If compiled with -DSCRUB_STANDALONE then a main() procedure is added and
+** this file becomes a standalone program that can be run as follows:

+*************************************************************************
+**
+** This file demonstrates how to create a table-valued-function using
+** a virtual table. This demo implements the generate_series() function
+** which gives similar results to the eponymous function in PostgreSQL.
+** Examples:
+**
+** SELECT * FROM generate_series(0,100,5);
+**
+** The query above returns integers from 0 through 100 counting by steps
+** of 5.
+**
+** SELECT * FROM generate_series(0,100);
+**
+** Integers from 0 through 100 with a step size of 1.
+**
+** SELECT * FROM generate_series(20) LIMIT 10;
+**
+** Integers 20 through 29.
+**
+** HOW IT WORKS
+**
+** The generate_series "function" is really a virtual table with the
+** following schema:
+**
+** CREATE TABLE generate_series(
+** value,
+** start HIDDEN,
+** stop HIDDEN,
+** step HIDDEN
+** );
+**
+** Function arguments in queries against this virtual table are translated
+** into equality constraints against successive hidden columns. In other
+** words, the following pairs of queries are equivalent to each other:
+**
+** SELECT * FROM generate_series(0,100,5);
+** SELECT * FROM generate_series WHERE start=0 AND stop=100 AND step=5;
+**
+** SELECT * FROM generate_series(0,100);
+** SELECT * FROM generate_series WHERE start=0 AND stop=100;
+**
+** SELECT * FROM generate_series(20) LIMIT 10;
+** SELECT * FROM generate_series WHERE start=20 LIMIT 10;
+**
+** The generate_series virtual table implementation leaves the xCreate method
+** set to NULL. This means that it is not possible to do a CREATE VIRTUAL
+** TABLE command with "generate_series" as the USING argument. Instead, there
+** is a single generate_series virtual table that is always available without
+** having to be created first.
+**
+** The xBestIndex method looks for equality constraints against the hidden
+** start, stop, and step columns, and if present, it uses those constraints
+** to bound the sequence of generated values. If the equality constraints
+** are missing, it uses 0 for start, 4294967295 for stop, and 1 for step.
+** xBestIndex returns a small cost when both start and stop are available,
+** and a very large cost if either start or stop are unavailable. This
+** encourages the query planner to order joins such that the bounds of the
+** series are well-defined.

+ the total number of pages in the file.
+
+Pages on the freelist
+
+ The number of pages that are not currently in use but are reserved for
+ future use. The percentage at the right is the number of freelist pages
+ divided by the total number of pages in the file.
+
+Pages of auto-vacuum overhead
+
+ The number of pages that store data used by the database to facilitate
+ auto-vacuum. This is zero for databases that do not support auto-vacuum.
+
+Number of tables in the database
+
+ The number of tables in the database, including the SQLITE_MASTER table
+ used to store schema information.
+
+Number of indices
+
+ The total number of indices in the database.
+
+Number of defined indices
+
+ The number of indices created using an explicit CREATE INDEX statement.
+
+Number of implied indices
+
+ The number of indices used to implement PRIMARY KEY or UNIQUE constraints
+ on tables.
+
+Size of the file in bytes
+
+ The total amount of disk space used by the entire database files.
+
+Bytes of user payload stored
+
+ The total number of bytes of user payload stored in the database. The
+ schema information in the SQLITE_MASTER table is not counted when
+ computing this number. The percentage at the right shows the payload
+ divided by the total file size.
+
+Percentage of total database
+
+ The amount of the complete database file that is devoted to storing
+ information described by this category.
+
+Number of entries
+
+ The total number of B-Tree key/value pairs stored under this category.
+
+Bytes of storage consumed
+
+ The total amount of disk space required to store all B-Tree entries
+ under this category. The is the total number of pages used times
+ the pages size.
+
+Bytes of payload
+
+ The amount of payload stored under this category. Payload is the data
+ part of table entries and the key part of index entries. The percentage
+ at the right is the bytes of payload divided by the bytes of storage
+ consumed.
+
+Bytes of metadata
+
+ The amount of formatting and structural information stored in the
+ table or index. Metadata includes the btree page header, the cell pointer
+ array, the size field for each cell, the left child pointer or non-leaf
+ cells, the overflow pointers for overflow cells, and the rowid value for
+ rowid table cells. In other words, metadata is everything that is neither
+ unused space nor content. The record header in the payload is counted as
+ content, not metadata.
+
+Average payload per entry
+
+ The average amount of payload on each entry. This is just the bytes of
+ payload divided by the number of entries.
+
+Average unused bytes per entry
+
+ The average amount of free space remaining on all pages under this
+ category on a per-entry basis. This is the number of unused bytes on
+ all pages divided by the number of entries.
+
+Non-sequential pages
+
+ The number of pages in the table or index that are out of sequence.
+ Many filesystems are optimized for sequential file access so a small
+ number of non-sequential pages might result in faster queries,
+ especially for larger database files that do not fit in the disk cache.
+ Note that after running VACUUM, the root page of each table or index is
+ at the beginning of the database file and all other pages are in a
+ separate part of the database file, resulting in a single non-
+ sequential page.
+
+Maximum payload per entry
+
+ The largest payload size of any entry.
+
+Entries that use overflow
+
+ The number of entries that user one or more overflow pages.
+
+Total pages used
+
+ This is the number of pages used to hold all information in the current
+ category. This is the sum of index, primary, and overflow pages.
+
+Index pages used
+
+ This is the number of pages in a table B-tree that hold only key (rowid)
+ information and no data.
+
+Primary pages used
+
+ This is the number of B-tree pages that hold both key and data.
+
+Overflow pages used
+
+ The total number of overflow pages used for this category.
+
+Unused bytes on index pages
+
+ The total number of bytes of unused space on all index pages. The
+ percentage at the right is the number of unused bytes divided by the
+ total number of bytes on index pages.
+
+Unused bytes on primary pages
+
+ The total number of bytes of unused space on all primary pages. The
+ percentage at the right is the number of unused bytes divided by the
+ total number of bytes on primary pages.
+
+Unused bytes on overflow pages
+
+ The total number of bytes of unused space on all overflow pages. The
+ percentage at the right is the number of unused bytes divided by the
+ total number of bytes on overflow pages.
+
+Unused bytes on all pages
+
+ The total number of bytes of unused space on all primary and overflow
+ pages. The percentage at the right is the number of unused bytes

+** Create a new delta.
+**
+** The delta is written into a preallocated buffer, zDelta, which
+** should be at least 60 bytes longer than the target file, zOut.
+** The delta string will be NUL-terminated, but it might also contain
+** embedded NUL characters if either the zSrc or zOut files are
+** binary. This function returns the length of the delta string
+** in bytes, excluding the final NUL terminator character.
+**
+** Output Format:
+**
+** The delta begins with a base64 number followed by a newline. This
+** number is the number of bytes in the TARGET file. Thus, given a
+** delta file z, a program can compute the size of the output file
+** simply by reading the first line and decoding the base-64 number
+** found there. The delta_output_size() routine does exactly this.
+**
+** After the initial size number, the delta consists of a series of
+** literal text segments and commands to copy from the SOURCE file.
+** A copy command looks like this:
+**
+** NNN@MMM,
+**
+** where NNN is the number of bytes to be copied and MMM is the offset
+** into the source file of the first byte (both base-64). If NNN is 0
+** it means copy the rest of the input file. Literal text is like this:
+**
+** NNN:TTTTT
+**
+** where NNN is the number of bytes of text (base-64) and TTTTT is the text.
+**
+** The last term is of the form
+**
+** NNN;
+**
+** In this case, NNN is a 32-bit bigendian checksum of the output file
+** that can be used to verify that the delta applied correctly. All
+** numbers are in base-64.
+**
+** Pure text files generate a pure text delta. Binary files generate a
+** delta that may contain some binary data.
+**
+** Algorithm:
+**
+** The encoder first builds a hash table to help it find matching
+** patterns in the source file. 16-byte chunks of the source file
+** sampled at evenly spaced intervals are used to populate the hash
+** table.
+**
+** Next we begin scanning the target file using a sliding 16-byte
+** window. The hash of the 16-byte window in the target is used to
+** search for a matching section in the source file. When a match
+** is found, a copy command is added to the delta. An effort is
+** made to extend the matching section to regions that come before
+** and after the 16-byte hash window. A copy command is only issued
+** if the result would use less space that just quoting the text
+** literally. Literal text is added to the delta for sections that
+** do not match or which can not be encoded efficiently using copy
+** commands.

+*************************************************************************
+**
+**
+** OVERVIEW
+**
+** The RBU extension requires that the RBU update be packaged as an
+** SQLite database. The tables it expects to find are described in
+** sqlite3rbu.h. Essentially, for each table xyz in the target database
+** that the user wishes to write to, a corresponding data_xyz table is
+** created in the RBU database and populated with one row for each row to
+** update, insert or delete from the target table.
+**
+** The update proceeds in three stages:
+**
+** 1) The database is updated. The modified database pages are written
+** to a *-oal file. A *-oal file is just like a *-wal file, except
+** that it is named "<database>-oal" instead of "<database>-wal".
+** Because regular SQLite clients do not look for file named
+** "<database>-oal", they go on using the original database in
+** rollback mode while the *-oal file is being generated.
+**
+** During this stage RBU does not update the database by writing
+** directly to the target tables. Instead it creates "imposter"
+** tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses
+** to update each b-tree individually. All updates required by each
+** b-tree are completed before moving on to the next, and all
+** updates are done in sorted key order.
+**
+** 2) The "<database>-oal" file is moved to the equivalent "<database>-wal"
+** location using a call to rename(2). Before doing this the RBU
+** module takes an EXCLUSIVE lock on the database file, ensuring
+** that there are no other active readers.
+**
+** Once the EXCLUSIVE lock is released, any other database readers
+** detect the new *-wal file and read the database in wal mode. At
+** this point they see the new version of the database - including
+** the updates made as part of the RBU update.
+**
+** 3) The new *-wal file is checkpointed. This proceeds in the same way
+** as a regular database checkpoint, except that a single frame is
+** checkpointed each time sqlite3rbu_step() is called. If the RBU
+** handle is closed before the entire *-wal file is checkpointed,
+** the checkpoint progress is saved in the RBU database and the
+** checkpoint can be resumed by another RBU client at some point in
+** the future.
+**
+** POTENTIAL PROBLEMS
+**
+** The rename() call might not be portable. And RBU is not currently
+** syncing the directory after renaming the file.
+**
+** When state is saved, any commit to the *-oal file and the commit to
+** the RBU update database are not atomic. So if the power fails at the
+** wrong moment they might get out of sync. As the main database will be
+** committed before the RBU update database this will likely either just
+** pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE
+** constraint violations).
+**
+** If some client does modify the target database mid RBU update, or some
+** other error occurs, the RBU extension will keep throwing errors. It's
+** not really clear how to get out of this state. The system could just
+** by delete the RBU update database and *-oal file and have the device
+** download the update again and start over.
+**
+** At present, for an UPDATE, both the new.* and old.* records are
+** collected in the rbu_xyz table. And for both UPDATEs and DELETEs all
+** fields are collected. This means we're probably writing a lot more
+** data to disk when saving the state of an ongoing update to the RBU
+** update database than is strictly necessary.

+/**************************************************************************
+** Beginning of RBU VFS shim methods. The VFS shim modifies the behaviour
+** of a standard VFS in the following ways:
+**
+** 1. Whenever the first page of a main database file is read or
+** written, the value of the change-counter cookie is stored in
+** rbu_file.iCookie. Similarly, the value of the "write-version"
+** database header field is stored in rbu_file.iWriteVer. This ensures
+** that the values are always trustworthy within an open transaction.
+**
+** 2. Whenever an SQLITE_OPEN_WAL file is opened, the (rbu_file.pWalFd)
+** member variable of the associated database file descriptor is set
+** to point to the new file. A mutex protected linked list of all main
+** db fds opened using a particular RBU VFS is maintained at
+** rbu_vfs.pMain to facilitate this.
+**
+** 3. Using a new file-control "SQLITE_FCNTL_RBU", a main db rbu_file
+** object can be marked as the target database of an RBU update. This
+** turns on the following extra special behaviour:
+**
+** 3a. If xAccess() is called to check if there exists a *-wal file
+** associated with an RBU target database currently in RBU_STAGE_OAL
+** stage (preparing the *-oal file), the following special handling
+** applies:
+**
+** * if the *-wal file does exist, return SQLITE_CANTOPEN. An RBU
+** target database may not be in wal mode already.
+**
+** * if the *-wal file does not exist, set the output parameter to
+** non-zero (to tell SQLite that it does exist) anyway.
+**
+** Then, when xOpen() is called to open the *-wal file associated with
+** the RBU target in RBU_STAGE_OAL stage, instead of opening the *-wal
+** file, the rbu vfs opens the corresponding *-oal file instead.
+**
+** 3b. The *-shm pages returned by xShmMap() for a target db file in
+** RBU_STAGE_OAL mode are actually stored in heap memory. This is to
+** avoid creating a *-shm file on disk. Additionally, xShmLock() calls
+** are no-ops on target database files in RBU_STAGE_OAL mode. This is
+** because assert() statements in some VFS implementations fail if
+** xShmLock() is called before xShmMap().
+**
+** 3c. If an EXCLUSIVE lock is attempted on a target database file in any
+** mode except RBU_STAGE_DONE (all work completed and checkpointed), it
+** fails with an SQLITE_BUSY error. This is to stop RBU connections
+** from automatically checkpointing a *-wal (or *-oal) file from within
+** sqlite3_close().
+**
+** 3d. In RBU_STAGE_CAPTURE mode, all xRead() calls on the wal file, and
+** all xWrite() calls on the target database file perform no IO.
+** Instead the frame and page numbers that would be read and written
+** are recorded. Additionally, successful attempts to obtain exclusive
+** xShmLock() WRITER, CHECKPOINTER and READ0 locks on the target
+** database file are recorded. xShmLock() calls to unlock the same
+** locks are no-ops (so that once obtained, these locks are never
+** relinquished). Finally, calls to xSync() on the target database
+** file fail with SQLITE_INTERNAL errors.

+** SUMMARY
+**
+** Writing a transaction containing a large number of operations on
+** b-tree indexes that are collectively larger than the available cache
+** memory can be very inefficient.
+**
+** The problem is that in order to update a b-tree, the leaf page (at least)
+** containing the entry being inserted or deleted must be modified. If the
+** working set of leaves is larger than the available cache memory, then a
+** single leaf that is modified more than once as part of the transaction
+** may be loaded from or written to the persistent media multiple times.
+** Additionally, because the index updates are likely to be applied in
+** random order, access to pages within the database is also likely to be in
+** random order, which is itself quite inefficient.
+**
+** One way to improve the situation is to sort the operations on each index
+** by index key before applying them to the b-tree. This leads to an IO
+** pattern that resembles a single linear scan through the index b-tree,
+** and all but guarantees each modified leaf page is loaded and stored
+** exactly once. SQLite uses this trick to improve the performance of
+** CREATE INDEX commands. This extension allows it to be used to improve
+** the performance of large transactions on existing databases.
+**
+** Additionally, this extension allows the work involved in writing the
+** large transaction to be broken down into sub-transactions performed
+** sequentially by separate processes. This is useful if the system cannot
+** guarantee that a single update process will run for long enough to apply
+** the entire update, for example because the update is being applied on a
+** mobile device that is frequently rebooted. Even after the writer process
+** has committed one or more sub-transactions, other database clients continue
+** to read from the original database snapshot. In other words, partially
+** applied transactions are not visible to other clients.
+**
+** "RBU" stands for "Resumable Bulk Update". As in a large database update
+** transmitted via a wireless network to a mobile device. A transaction
+** applied using this extension is hence refered to as an "RBU update".
+**
+**
+** LIMITATIONS
+**
+** An "RBU update" transaction is subject to the following limitations:
+**
+** * The transaction must consist of INSERT, UPDATE and DELETE operations
+** only.
+**
+** * INSERT statements may not use any default values.
+**
+** * UPDATE and DELETE statements must identify their target rows by
+** non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY
+** KEY fields may not be updated or deleted. If the table being written
+** has no PRIMARY KEY, affected rows must be identified by rowid.
+**
+** * UPDATE statements may not modify PRIMARY KEY columns.
+**
+** * No triggers will be fired.
+**
+** * No foreign key violations are detected or reported.
+**
+** * CHECK constraints are not enforced.
+**
+** * No constraint handling mode except for "OR ROLLBACK" is supported.
+**
+**
+** PREPARATION
+**
+** An "RBU update" is stored as a separate SQLite database. A database
+** containing an RBU update is an "RBU database". For each table in the
+** target database to be updated, the RBU database should contain a table
+** named "data_<target name>" containing the same set of columns as the
+** target table, and one more - "rbu_control". The data_% table should
+** have no PRIMARY KEY or UNIQUE constraints, but each column should have
+** the same type as the corresponding column in the target database.
+** The "rbu_control" column should have no type at all. For example, if
+** the target database contains:
+**
+** CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE);
+**
+** Then the RBU database should contain:
+**
+** CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control);
+**
+** The order of the columns in the data_% table does not matter.
+**
+** Instead of a regular table, the RBU database may also contain virtual
+** tables or view named using the data_<target> naming scheme.
+**
+** Instead of the plain data_<target> naming scheme, RBU database tables
+** may also be named data<integer>_<target>, where <integer> is any sequence
+** of zero or more numeric characters (0-9). This can be significant because
+** tables within the RBU database are always processed in order sorted by
+** name. By judicious selection of the <integer> portion of the names
+** of the RBU tables the user can therefore control the order in which they
+** are processed. This can be useful, for example, to ensure that "external
+** content" FTS4 tables are updated before their underlying content tables.
+**
+** If the target database table is a virtual table or a table that has no
+** PRIMARY KEY declaration, the data_% table must also contain a column
+** named "rbu_rowid". This column is mapped to the tables implicit primary
+** key column - "rowid". Virtual tables for which the "rowid" column does
+** not function like a primary key value cannot be updated using RBU. For
+** example, if the target db contains either of the following:
+**
+** CREATE VIRTUAL TABLE x1 USING fts3(a, b);
+** CREATE TABLE x1(a, b)
+**
+** then the RBU database should contain:
+**
+** CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control);
+**
+** All non-hidden columns (i.e. all columns matched by "SELECT *") of the
+** target table must be present in the input table. For virtual tables,
+** hidden columns are optional - they are updated by RBU if present in
+** the input table, or not otherwise. For example, to write to an fts4
+** table with a hidden languageid column such as:
+**
+** CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid');
+**
+** Either of the following input table schemas may be used:
+**
+** CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control);
+** CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control);
+**
+** For each row to INSERT into the target database as part of the RBU
+** update, the corresponding data_% table should contain a single record
+** with the "rbu_control" column set to contain integer value 0. The
+** other columns should be set to the values that make up the new record
+** to insert.
+**
+** If the target database table has an INTEGER PRIMARY KEY, it is not
+** possible to insert a NULL value into the IPK column. Attempting to
+** do so results in an SQLITE_MISMATCH error.
+**
+** For each row to DELETE from the target database as part of the RBU
+** update, the corresponding data_% table should contain a single record
+** with the "rbu_control" column set to contain integer value 1. The
+** real primary key values of the row to delete should be stored in the
+** corresponding columns of the data_% table. The values stored in the
+** other columns are not used.
+**
+** For each row to UPDATE from the target database as part of the RBU
+** update, the corresponding data_% table should contain a single record
+** with the "rbu_control" column set to contain a value of type text.
+** The real primary key values identifying the row to update should be
+** stored in the corresponding columns of the data_% table row, as should
+** the new values of all columns being update. The text value in the
+** "rbu_control" column must contain the same number of characters as
+** there are columns in the target database table, and must consist entirely
+** of 'x' and '.' characters (or in some special cases 'd' - see below). For
+** each column that is being updated, the corresponding character is set to
+** 'x'. For those that remain as they are, the corresponding character of the
+** rbu_control value should be set to '.'. For example, given the tables
+** above, the update statement:
+**
+** UPDATE t1 SET c = 'usa' WHERE a = 4;
+**
+** is represented by the data_t1 row created by:
+**
+** INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x');
+**
+** Instead of an 'x' character, characters of the rbu_control value specified
+** for UPDATEs may also be set to 'd'. In this case, instead of updating the
+** target table with the value stored in the corresponding data_% column, the
+** user-defined SQL function "rbu_delta()" is invoked and the result stored in
+** the target table column. rbu_delta() is invoked with two arguments - the
+** original value currently stored in the target table column and the
+** value specified in the data_xxx table.
+**
+** For example, this row:
+**
+** INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d');
+**
+** is similar to an UPDATE statement such as:
+**
+** UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;
+**
+** Finally, if an 'f' character appears in place of a 'd' or 's' in an
+** ota_control string, the contents of the data_xxx table column is assumed
+** to be a "fossil delta" - a patch to be applied to a blob value in the
+** format used by the fossil source-code management system. In this case
+** the existing value within the target database table must be of type BLOB.
+** It is replaced by the result of applying the specified fossil delta to
+** itself.
+**
+** If the target database table is a virtual table or a table with no PRIMARY
+** KEY, the rbu_control value should not include a character corresponding
+** to the rbu_rowid value. For example, this:
+**
+** INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control)
+** VALUES(NULL, 'usa', 12, '.x');
+**
+** causes a result similar to:
+**
+** UPDATE ft1 SET b = 'usa' WHERE rowid = 12;
+**
+** The data_xxx tables themselves should have no PRIMARY KEY declarations.
+** However, RBU is more efficient if reading the rows in from each data_xxx
+** table in "rowid" order is roughly the same as reading them sorted by
+** the PRIMARY KEY of the corresponding target database table. In other
+** words, rows should be sorted using the destination table PRIMARY KEY
+** fields before they are inserted into the data_xxx tables.
+**
+** USAGE
+**
+** The API declared below allows an application to apply an RBU update
+** stored on disk to an existing target database. Essentially, the
+** application:
+**
+** 1) Opens an RBU handle using the sqlite3rbu_open() function.
+**
+** 2) Registers any required virtual table modules with the database
+** handle returned by sqlite3rbu_db(). Also, if required, register
+** the rbu_delta() implementation.
+**
+** 3) Calls the sqlite3rbu_step() function one or more times on
+** the new handle. Each call to sqlite3rbu_step() performs a single
+** b-tree operation, so thousands of calls may be required to apply
+** a complete update.
+**
+** 4) Calls sqlite3rbu_close() to close the RBU update handle. If
+** sqlite3rbu_step() has been called enough times to completely
+** apply the update to the target database, then the RBU database
+** is marked as fully applied. Otherwise, the state of the RBU
+** update application is saved in the RBU database for later
+** resumption.
+**
+** See comments below for more detail on APIs.
+**
+** If an update is only partially applied to the target database by the
+** time sqlite3rbu_close() is called, various state information is saved
+** within the RBU database. This allows subsequent processes to automatically
+** resume the RBU update from where it left off.
+**
+** To remove all RBU extension state information, returning an RBU database
+** to its original contents, it is sufficient to drop all tables that begin
+** with the prefix "rbu_"
+**
+** DATABASE LOCKING
+**
+** An RBU update may not be applied to a database in WAL mode. Attempting
+** to do so is an error (SQLITE_ERROR).
+**
+** While an RBU handle is open, a SHARED lock may be held on the target
+** database file. This means it is possible for other clients to read the
+** database, but not to write it.
+**
+** If an RBU update is started and then suspended before it is completed,
+** then an external client writes to the database, then attempting to resume
+** the suspended RBU update is also an error (SQLITE_BUSY).

+** Create an RBU VFS named zName that accesses the underlying file-system
+** via existing VFS zParent. Or, if the zParent parameter is passed NULL,
+** then the new RBU VFS uses the default system VFS to access the file-system.
+** The new object is registered as a non-default VFS with SQLite before
+** returning.
+**
+** Part of the RBU implementation uses a custom VFS object. Usually, this
+** object is created and deleted automatically by RBU.
+**
+** The exception is for applications that also use zipvfs. In this case,
+** the custom VFS must be explicitly created by the user before the RBU
+** handle is opened. The RBU VFS should be installed so that the zipvfs
+** VFS uses the RBU VFS, which in turn uses any other VFS layers in use
+** (for example multiplexor) to access the file-system. For example,
+** to assemble an RBU enabled VFS stack that uses both zipvfs and
+** multiplexor (error checking omitted):
+**
+** // Create a VFS named "multiplex" (not the default).
+** sqlite3_multiplex_initialize(0, 0);
+**
+** // Create an rbu VFS named "rbu" that uses multiplexor. If the
+** // second argument were replaced with NULL, the "rbu" VFS would
+** // access the file-system via the system default VFS, bypassing the
+** // multiplexor.
+** sqlite3rbu_create_vfs("rbu", "multiplex");
+**
+** // Create a zipvfs VFS named "zipvfs" that uses rbu.
+** zipvfs_create_vfs_v3("zipvfs", "rbu", 0, xCompressorAlgorithmDetector);
+**
+** // Make zipvfs the default VFS.
+** sqlite3_vfs_register(sqlite3_vfs_find("zipvfs"), 1);
+**
+** Because the default VFS created above includes a RBU functionality, it
+** may be used by RBU clients. Attempting to use RBU with a zipvfs VFS stack
+** that does not include the RBU layer results in an error.
+**
+** The overhead of adding the "rbu" VFS to the system is negligible for
+** non-RBU users. There is no harm in an application accessing the
+** file-system via "rbu" all the time, even if it only uses RBU functionality
+** occasionally.

+**
+** This file implements a template virtual-table.
+** Developers can make a copy of this file as a baseline for writing
+** new virtual tables and/or table-valued functions.
+**
+** Steps for writing a new virtual table implementation:
+**
+** (1) Make a copy of this file. Perhaps call it "mynewvtab.c"
+**
+** (2) Replace this header comment with something appropriate for
+** the new virtual table
+**
+** (3) Change every occurrence of "templatevtab" to some other string
+** appropriate for the new virtual table. Ideally, the new string
+** should be the basename of the source file: "mynewvtab". Also
+** globally change "TEMPLATEVTAB" to "MYNEWVTAB".
+**
+** (4) Run a test compilation to make sure the unmodified virtual
+** table works.
+**
+** (5) Begin making incremental changes, testing as you go, to evolve
+** the new virtual table to do what you want it to do.
+**
+** This template is minimal, in the sense that it uses only the required
+** methods on the sqlite3_module object. As a result, templatevtab is
+** a read-only and eponymous-only table. Those limitation can be removed
+** by adding new methods.
+**
+** This template implements an eponymous-only virtual table with a rowid and
+** two columns named "a" and "b". The table as 10 rows with fixed integer
+** values. Usage example:
+**
+** SELECT rowid, a, b FROM templatevtab;

+*************************************************************************
+**
+** This file contains the implementation of the "unionvtab" and "swarmvtab"
+** virtual tables. These modules provide read-only access to multiple tables,
+** possibly in multiple database files, via a single database object.
+** The source tables must have the following characteristics:
+**
+** * They must all be rowid tables (not VIRTUAL or WITHOUT ROWID
+** tables or views).
+**
+** * Each table must have the same set of columns, declared in
+** the same order and with the same declared types.
+**
+** * The tables must not feature a user-defined column named "_rowid_".
+**
+** * Each table must contain a distinct range of rowid values.
+**
+** The difference between the two virtual table modules is that for
+** "unionvtab", all source tables must be located in the main database or
+** in databases ATTACHed to the main database by the user. For "swarmvtab",
+** the tables may be located in any database file on disk. The "swarmvtab"
+** implementation takes care of opening and closing database files
+** automatically.
+**
+** UNIONVTAB
+**
+** A "unionvtab" virtual table is created as follows:
+**
+** CREATE VIRTUAL TABLE <name> USING unionvtab(<sql-statement>);
+**
+** The implementation evalutes <sql statement> whenever a unionvtab virtual
+** table is created or opened. It should return one row for each source
+** database table. The four columns required of each row are:
+**
+** 1. The name of the database containing the table ("main" or "temp" or
+** the name of an attached database). Or NULL to indicate that all
+** databases should be searched for the table in the usual fashion.
+**
+** 2. The name of the database table.
+**
+** 3. The smallest rowid in the range of rowids that may be stored in the
+** database table (an integer).
+**
+** 4. The largest rowid in the range of rowids that may be stored in the
+** database table (an integer).
+**
+** SWARMVTAB
+**
+** LEGACY SYNTAX:
+**
+** A "swarmvtab" virtual table is created similarly to a unionvtab table:
+**
+** CREATE VIRTUAL TABLE <name>
+** USING swarmvtab(<sql-statement>, <callback>);
+**
+** The difference is that for a swarmvtab table, the first column returned
+** by the <sql statement> must return a path or URI that can be used to open
+** the database file containing the source table. The <callback> option
+** is optional. If included, it is the name of an application-defined
+** SQL function that is invoked with the URI of the file, if the file
+** does not already exist on disk when required by swarmvtab.
+**
+** NEW SYNTAX:
+**
+** Using the new syntax, a swarmvtab table is created with:
+**
+** CREATE VIRTUAL TABLE <name> USING swarmvtab(
+** <sql-statement> [, <options>]
+** );
+**
+** where valid <options> are:
+**
+** missing=<udf-function-name>
+** openclose=<udf-function-name>
+** maxopen=<integer>
+** <sql-parameter>=<text-value>
+**
+** The <sql-statement> must return the same 4 columns as for a swarmvtab
+** table in legacy mode. However, it may also return a 5th column - the
+** "context" column. The text value returned in this column is not used
+** at all by the swarmvtab implementation, except that it is passed as
+** an additional argument to the two UDF functions that may be invoked
+** (see below).
+**
+** The "missing" option, if present, specifies the name of an SQL UDF
+** function to be invoked if a database file is not already present on
+** disk when required by swarmvtab. If the <sql-statement> did not provide
+** a context column, it is invoked as:
+**
+** SELECT <missing-udf>(<database filename/uri>);
+**
+** Or, if there was a context column:
+**
+** SELECT <missing-udf>(<database filename/uri>, <context>);
+**
+** The "openclose" option may also specify a UDF function. This function
+** is invoked right before swarmvtab opens a database, and right after
+** it closes one. The first argument - or first two arguments, if
+** <sql-statement> supplied the context column - is the same as for
+** the "missing" UDF. Following this, the UDF is passed integer value
+** 0 before a db is opened, and 1 right after it is closed. If both
+** a missing and openclose UDF is supplied, the application should expect
+** the following sequence of calls (for a single database):
+**
+** SELECT <openclose-udf>(<db filename>, <context>, 0);
+** if( db not already on disk ){
+** SELECT <missing-udf>(<db filename>, <context>);
+** }
+** ... swarmvtab uses database ...
+** SELECT <openclose-udf>(<db filename>, <context>, 1);
+**
+** The "maxopen" option is used to configure the maximum number of
+** database files swarmvtab will hold open simultaneously (default 9).
+**
+** If an option name begins with a ":" character, then it is assumed
+** to be an SQL parameter. In this case, the specified text value is
+** bound to the same variable of the <sql-statement> before it is
+** executed. It is an error of the named SQL parameter does not exist.
+** For example:
+**
+** CREATE VIRTUAL TABLE swarm USING swarmvtab(
+** 'SELECT :path || localfile, tbl, min, max FROM swarmdir',
+** :path='/home/user/databases/'
+** missing='missing_func'
+** );

+*/
+
+/*
+** This module contains code for a wrapper VFS that causes a log of
+** most VFS calls to be written into a file on disk.
+**
+** Each database connection creates a separate log file in the same
+** directory as the original database and named after the original
+** database. A unique suffix is added to avoid name collisions.
+** Separate log files are used so that concurrent processes do not
+** try to write log operations to the same file at the same instant,
+** resulting in overwritten or comingled log text.
+**
+** Each individual log file records operations by a single database
+** connection on both the original database and its associated rollback
+** journal.
+**
+** The log files are in the comma-separated-value (CSV) format. The
+** log files can be imported into an SQLite database using the ".import"
+** command of the SQLite command-line shell for analysis.
+**
+** One technique for using this module is to append the text of this
+** module to the end of a standard "sqlite3.c" amalgamation file then
+** add the following compile-time options:
+**
+** -DSQLITE_EXTRA_INIT=sqlite3_register_vfslog
+** -DSQLITE_USE_FCNTL_TRACE
+**
+** The first compile-time option causes the sqlite3_register_vfslog()
+** function, defined below, to be invoked when SQLite is initialized.
+** That causes this custom VFS to become the default VFS for all
+** subsequent connections. The SQLITE_USE_FCNTL_TRACE option causes
+** the SQLite core to issue extra sqlite3_file_control() operations
+** with SQLITE_FCNTL_TRACE to give some indication of what is going
+** on in the core.

+
+/*
+** This module contains code for a wrapper VFS that cause stats for
+** most VFS calls to be recorded.
+**
+** To use this module, first compile it as a loadable extension. See
+** https://www.sqlite.org/loadext.html#build for compilations instructions.
+**
+** After compliing, load this extension, then open database connections to be
+** measured. Query usages status using the vfsstat virtual table:
+**
+** SELECT * FROM vfsstat;
+**
+** Reset counters using UPDATE statements against vfsstat:
+**
+** UPDATE vfsstat SET count=0;
+**
+** EXAMPLE SCRIPT:
+**
+** .load ./vfsstat
+** .open test.db
+** DROP TABLE IF EXISTS t1;
+** CREATE TABLE t1(x,y);
+** INSERT INTO t1 VALUES(123, randomblob(5000));
+** CREATE INDEX t1x ON t1(x);
+** DROP TABLE t1;
+** VACUUM;
+** SELECT * FROM vfsstat WHERE count>0;
+**
+** LIMITATIONS:
+**
+** This module increments counters without using mutex protection. So if
+** two or more threads try to use this module at the same time, race conditions
+** may occur which mess up the counts. This is harmless, other than giving
+** incorrect statistics.
