-# use the autoconf generated "configure" script to generate the
-# makefile automatically. But that does not work for everybody
-# and in every situation. If you are having problems with the
-# "configure" script, you might want to try this makefile as an
-# alternative. Create a copy of this file, edit the parameters
-# below and type "make".

-This directory contains source code to
-
- SQLite: An Embeddable SQL Database Engine
-
-To compile the project, first create a directory in which to place
-the build products. It is recommended, but not required, that the
-build directory be separate from the source directory. Cd into the
-build directory and then from the build directory run the configure
-script found at the root of the source tree. Then run "make".
-
-For example:
-
- tar xzf sqlite.tar.gz ;# Unpack the source tree into "sqlite"
- mkdir bld ;# Build will occur in a sibling directory
- cd bld ;# Change to the build directory
- ../sqlite/configure ;# Run the configure script
- make ;# Run the makefile.
- make install ;# (Optional) Install the build products
-
-The configure script uses autoconf 2.50 and libtool. If the configure
-script does not work out for you, there is a generic makefile named
-"Makefile.linux-gcc" in the top directory of the source tree that you
-can copy and edit to suite your needs. Comments on the generic makefile
-show what changes are needed.
-
-The linux binaries on the website are created using the generic makefile,
-not the configure script. The configure script is unmaintained. (You
-can volunteer to take over maintenance of the configure script, if you want!)
-The windows binaries on the website are created using MinGW32 configured
-as a cross-compiler running under Linux. For details, see the ./publish.sh
-script at the top-level of the source tree.

-# The build process allows for using a cross-compiler. But the default

-# build and target systems:
-#
-# srcdir
-#
-# The is the name of the directory that contains the
-# "configure" shell script. All source files are
-# located relative to this directory.
-#
-# bindir
-#
-# The name of the directory where executables should be
-# written by the "install" target of the makefile.
-#
-# program_prefix
-#
-# Add this prefix to the names of all executables that run
-# on the target machine. Default: ""
-#
-# ENABLE_SHARED
-#
-# True if shared libraries should be generated.
-#
-# BUILD_CC
-#
-# The name of a command that is used to convert C
-# source files into executables that run on the build
-# platform.
-#
-# BUILD_CFLAGS
-#
-# Switches that the build compiler needs in order to construct
-# command-line programs.
-#
-# BUILD_LIBS
-#
-# Libraries that the build compiler needs in order to construct
-# command-line programs.
-#
-# BUILD_EXEEXT
-#
-# The filename extension for executables on the build
-# platform. "" for Unix and ".exe" for Windows.
-#
-# TCL_*
-#
-# Lots of values are read in from the tclConfig.sh script,
-# if that script is available. This values are used for
-# constructing and installing the TCL extension.
-#
-# TARGET_READLINE_LIBS
-#
-# This is the library directives passed to the target linker
-# that cause the executable to link against the readline library.
-# This might be a switch like "-lreadline" or pathnames of library
-# file like "../../src/libreadline.a".
-#
-# TARGET_READLINE_INC

-# If you have a file that sets one or more of these environment
-# variables, you can invoke configure as follows:
-#
-# configure --with-hints=FILE
-#
-# where FILE is the name of the file that sets the environment
-# variables. FILE should be an absolute pathname.
-#
-# This configure.in file is easy to reuse on other projects. Just
-# change the argument to AC_INIT(). And disable any features that

- -all-static do not do any dynamic linking at all
- -avoid-version do not add a version suffix if possible
- -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
- -dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols

- -module build a library that can dlopened
- -no-fast-install disable the fast-install mode
- -no-install link a not-installable executable
- -no-undefined declare that a library does not refer to external symbols
- -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
- -objectlist FILE Use a list of object files found in FILE to specify objects
- -precious-files-regex REGEX
- don't remove output files matching REGEX
- -release RELEASE specify package release information
- -rpath LIBDIR the created library will eventually be installed in LIBDIR
- -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
- -static do not do any dynamic linking of libtool libraries

-only library objects (\`.lo' files) may be specified, and \`-rpath' is
-required, except when creating a convenience library.

-# Generate the file opcodes.h.
-#
-# This AWK script scans a concatenation of the parse.h output file from the
-# parser and the vdbe.c source file in order to generate the opcodes numbers
-# for all opcodes.
-#
-# The lines of the vdbe.c that we are interested in are of the form:
-#
-# case OP_aaaa: /* same as TK_bbbbb */
-#
-# The TK_ comment is optional. If it is present, then the value assigned to
-# the OP_ is the same as the TK_ value. If missing, the OP_ value is assigned
-# a small integer that is different from every other OP_ value.
-#
-# We go to the trouble of making some OP_ values the same as TK_ values
-# as an optimization. During parsing, things like expression operators
-# are coded with TK_ values such as TK_ADD, TK_DIVIDE, and so forth. Later
-# during code generation, we need to generate corresponding opcodes like
-# OP_Add and OP_Divide. By making TK_ADD==OP_Add and TK_DIVIDE==OP_Divide,
-# code to translate from one to the other is avoided. This makes the
-# code generator run (infinitesimally) faster and more importantly it makes
-# the library footprint smaller.
-#
-# This script also scans for lines of the form:
-#
-# case OP_aaaa: /* no-push */
-#
-# When the no-push comment is found on an opcode, it means that that
-# opcode does not leave a result on the stack. By identifying which
-# opcodes leave results on the stack it is possible to determine a
-# much smaller upper bound on the size of the stack. This allows
-# a smaller stack to be allocated, which is important to embedded
-# systems with limited memory space. This script generates a series
-# of "NOPUSH_MASK" defines that contain bitmaps of opcodes that leave
-# results on the stack. The NOPUSH_MASK defines are used in vdbeaux.c
-# to help determine the maximum stack size.

-.SH NAME
-sqlite \- A command line interface for SQLite
-.SH SYNOPSIS
-.B sqlite
-.RI [ options ] " filename " [ SQL ]
-.SS SUMMARY
-.PP
-sqlite is a terminal-based front-end to the SQLite library. It enables
-you to type in queries interactively, issue them to SQLite and see the
-results. Alternatively, you can specify SQL code on the command-line. In
-addition it provides a number of meta-commands.
-
-.SH DESCRIPTION
-This manual page documents briefly the
-.B sqlite
-command.
-This manual page was written for the Debian GNU/Linux distribution
-because the original program does not have a manual page.
-.SS GETTING STARTED
-.PP
-To start the sqlite program, just type "sqlite" followed by the name
-the file that holds the SQLite database. If the file does not exist, a
-new one is created automatically. The sqlite program will then prompt
-you to enter SQL. Type in SQL statements (terminated by a semicolon),
-press "Enter" and the SQL will be executed.
-
-For example, to create a new SQLite database named "ex1" with a single
-table named "tbl1", you might do this:
-.sp
-.nf
-$ sqlite ex1
-SQLite version 2.0.0
-Enter ".help" for instructions
-sqlite> create table tbl1(one varchar(10), two smallint);
-sqlite> insert into tbl1 values('hello!',10);
-sqlite> insert into tbl1 values('goodbye', 20);
-sqlite> select * from tbl1;
-hello!|10
-goodbye|20
-sqlite>
-.sp
-.fi
-
-.SS SQLITE META-COMMANDS
-.PP
-Most of the time, sqlite just reads lines of input and passes them on
-to the SQLite library for execution. But if an input line begins with
-a dot ("."), then that line is intercepted and interpreted by the
-sqlite program itself. These "dot commands" are typically used to
-change the output format of queries, or to execute certain prepackaged
-query statements.
-
-For a listing of the available dot commands, you can enter ".help" at
-any time. For example:
-.sp
-.nf
-.cc |
-sqlite> .help
-.dump ?TABLE? ... Dump the database in an text format
-.echo ON|OFF Turn command echo on or off
-.exit Exit this program
-.explain ON|OFF Turn output mode suitable for EXPLAIN on or off.
- "off" will revert to the output mode that was
- previously in effect
-.header(s) ON|OFF Turn display of headers on or off
-.help Show this message
-.indices TABLE Show names of all indices on TABLE
-.mode MODE Set mode to one of "line(s)", "column(s)",
- "insert", "list", or "html"
-.mode insert TABLE Generate SQL insert statements for TABLE
-.nullvalue STRING Print STRING instead of nothing for NULL data
-.output FILENAME Send output to FILENAME
-.output stdout Send output to the screen
-.prompt MAIN CONTINUE Replace the standard prompts
- "sqlite > " and " ...> "
- with the strings MAIN and CONTINUE
- CONTINUE is optional.
-.quit Exit this program
-.read FILENAME Execute SQL in FILENAME
-.reindex ?TABLE? Rebuild indices
-.schema ?TABLE? Show the CREATE statements
-.separator STRING Change separator string for "list" mode
-.show Show the current values for the following:
- .echo
- .explain
- .mode
- .nullvalue
- .output
- .separator
- .width
-.tables ?PATTERN? List names of tables matching a pattern
-.timeout MS Try opening locked tables for MS milliseconds
-.width NUM NUM ... Set column widths for "column" mode
-sqlite>
-|cc .
-.sp
-.fi
-
-.SH OPTIONS
-The program has the following options:
-.TP
-.BI \-init\ file
-Read in and process 'file', which contains "dot commands".
-You can use this file to initialize display settings.
-.TP
-.B \-html
-Set output mode to HTML.
-.TP
-.B \-list
-Set output mode to 'list'.
-.TP
-.B \-line
-Set output mode to 'line'.
-.TP
-.B \-column
-Set output mode to 'column'.
-.TP
-.BI \-separator\ separator
-Specify which output field separator for 'list' mode to use.
-Default is '|'.
-.TP
-.BI \-nullvalue\ string
-When a null is encountered, print 'string'. Default is no string.
-.TP
-.B \-[no]header
-Turn headers on or off. Default is off.
-.TP
-.B \-echo
-Print commands before execution.
-
-
-.SH OUTPUT MODE
-The SQLite program has different output modes, which define the way
-the output (from queries) is formatted.
-
-In 'list' mode, which is the default, one record per line is output,
-each field separated by the separator specified with the
-\fB-separator\fP option or \fB.separator\fP command.
-
-In 'line' mode, each column is output on its own line, records are
-separated by blank lines.
-
-In HTML mode, an XHTML table is generated.
-
-In 'column' mode, one record per line is output, aligned neatly in colums.
-
-.SH INIT FILE
-sqlite can be initialized using resource files. These can be combined with
-command line arguments to set up sqlite exactly the way you want it.
-Initialization proceeds as follows:
-
-o The defaults of
-
-.sp
-.nf
-.cc |
-mode = LIST
-separator = "|"
-main prompt = "sqlite> "
-continue prompt = " ...> "
-|cc .
-.sp
-.fi
-
-are established.
-
-o If a file .sqliterc can be found in the user's home directory, it is
-read and processed. It should only contain "dot commands". If the
-file is not found or cannot be read, processing continues without
-notification.
-
-o If a file is specified on the command line with the -init option, it
-is processed in the same manner as .sqliterc
-
-o All other command line options are processed
-
-o The database is opened and you are now ready to begin.

-** This routine redistributes Cells on pPage and up to NN*2 siblings

-** though more siblings might come from one side if pPage is the first
-** or last child of its parent. If pPage has fewer than 2*NN siblings
-** (something which can only happen if pPage is the root page or a
-** child of root) then all available siblings participate in the balancing.
-**
-** The number of siblings of pPage might be increased or decreased by one or
-** two in an effort to keep pages nearly full but not over full. The root page
-** is special and is allowed to be nearly empty. If pPage is
-** the root page, then the depth of the tree might be increased
-** or decreased by one, as necessary, to keep the root page from being
-** overfull or completely empty.
-**
-** Note that when this routine is called, some of the Cells on pPage
-** might not actually be stored in pPage->aData[]. This can happen
-** if the page is overfull. Part of the job of this routine is to
-** make sure all Cells for pPage once again fit in pPage->aData[].
-**
-** In the course of balancing the siblings of pPage, the parent of pPage
-** might become overfull or underfull. If that happens, then this routine
-** is called recursively on the parent.
-**
-** If this routine fails for any reason, it might leave the database
-** in a corrupted state. So if this routine fails, the database should

-*************************************************************************
-** $Id$
-**
-** This file implements a external (disk-based) database using BTrees.
-** For a detailed discussion of BTrees, refer to
-**
-** Donald E. Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3:
-** "Sorting And Searching", pages 473-480. Addison-Wesley
-** Publishing Company, Reading, Massachusetts.
-**
-** The basic idea is that each page of the file contains N database
-** entries and N+1 pointers to subpages.
-**
-** ----------------------------------------------------------------
-** | Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) |
-** ----------------------------------------------------------------
-**
-** All of the keys on the page that Ptr(0) points to have values less
-** than Key(0). All of the keys on page Ptr(1) and its subpages have
-** values greater than Key(0) and less than Key(1). All of the keys
-** on Ptr(N) and its subpages have values greater than Key(N-1). And
-** so forth.
-**
-** Finding a particular key requires reading O(log(M)) pages from the
-** disk where M is the number of entries in the tree.
-**
-** In this implementation, a single file can hold one or more separate
-** BTrees. Each BTree is identified by the index of its root page. The
-** key and data for any entry are combined to form the "payload". A
-** fixed amount of payload can be carried directly on the database
-** page. If the payload is larger than the preset amount then surplus
-** bytes are stored on overflow pages. The payload for an entry
-** and the preceding pointer are combined to form a "Cell". Each
-** page has a small header which contains the Ptr(N) pointer and other
-** information such as the size of key and data.
-**
-** FORMAT DETAILS
-**
-** The file is divided into pages. The first page is called page 1,
-** the second is page 2, and so forth. A page number of zero indicates
-** "no such page". The page size can be anything between 512 and 65536.
-** Each page can be either a btree page, a freelist page or an overflow
-** page.
-**
-** The first page is always a btree page. The first 100 bytes of the first
-** page contain a special header (the "file header") that describes the file.
-** The format of the file header is as follows:
-**
-** OFFSET SIZE DESCRIPTION
-** 0 16 Header string: "SQLite format 3\000"
-** 16 2 Page size in bytes.
-** 18 1 File format write version
-** 19 1 File format read version
-** 20 1 Bytes of unused space at the end of each page
-** 21 1 Max embedded payload fraction
-** 22 1 Min embedded payload fraction
-** 23 1 Min leaf payload fraction
-** 24 4 File change counter
-** 28 4 Reserved for future use
-** 32 4 First freelist page
-** 36 4 Number of freelist pages in the file
-** 40 60 15 4-byte meta values passed to higher layers
-**
-** All of the integer values are big-endian (most significant byte first).
-**
-** The file change counter is incremented when the database is changed
-** This counter allows other processes to know when the file has changed
-** and thus when they need to flush their cache.
-**
-** The max embedded payload fraction is the amount of the total usable
-** space in a page that can be consumed by a single cell for standard
-** B-tree (non-LEAFDATA) tables. A value of 255 means 100%. The default
-** is to limit the maximum cell size so that at least 4 cells will fit
-** on one page. Thus the default max embedded payload fraction is 64.
-**
-** If the payload for a cell is larger than the max payload, then extra
-** payload is spilled to overflow pages. Once an overflow page is allocated,
-** as many bytes as possible are moved into the overflow pages without letting
-** the cell size drop below the min embedded payload fraction.
-**
-** The min leaf payload fraction is like the min embedded payload fraction
-** except that it applies to leaf nodes in a LEAFDATA tree. The maximum
-** payload fraction for a LEAFDATA tree is always 100% (or 255) and it
-** not specified in the header.
-**
-** Each btree pages is divided into three sections: The header, the
-** cell pointer array, and the cell content area. Page 1 also has a 100-byte
-** file header that occurs before the page header.
-**
-** |----------------|
-** | file header | 100 bytes. Page 1 only.
-** |----------------|
-** | page header | 8 bytes for leaves. 12 bytes for interior nodes
-** |----------------|
-** | cell pointer | | 2 bytes per cell. Sorted order.
-** | array | | Grows downward
-** | | v
-** |----------------|
-** | unallocated |
-** | space |
-** |----------------| ^ Grows upwards
-** | cell content | | Arbitrary order interspersed with freeblocks.
-** | area | | and free space fragments.
-** |----------------|
-**
-** The page headers looks like this:
-**
-** OFFSET SIZE DESCRIPTION
-** 0 1 Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
-** 1 2 byte offset to the first freeblock
-** 3 2 number of cells on this page
-** 5 2 first byte of the cell content area
-** 7 1 number of fragmented free bytes
-** 8 4 Right child (the Ptr(N) value). Omitted on leaves.
-**
-** The flags define the format of this btree page. The leaf flag means that
-** this page has no children. The zerodata flag means that this page carries
-** only keys and no data. The intkey flag means that the key is a integer
-** which is stored in the key size entry of the cell header rather than in
-** the payload area.
-**
-** The cell pointer array begins on the first byte after the page header.
-** The cell pointer array contains zero or more 2-byte numbers which are
-** offsets from the beginning of the page to the cell content in the cell
-** content area. The cell pointers occur in sorted order. The system strives
-** to keep free space after the last cell pointer so that new cells can
-** be easily added without having to defragment the page.
-**
-** Cell content is stored at the very end of the page and grows toward the
-** beginning of the page.
-**
-** Unused space within the cell content area is collected into a linked list of
-** freeblocks. Each freeblock is at least 4 bytes in size. The byte offset
-** to the first freeblock is given in the header. Freeblocks occur in
-** increasing order. Because a freeblock must be at least 4 bytes in size,
-** any group of 3 or fewer unused bytes in the cell content area cannot
-** exist on the freeblock chain. A group of 3 or fewer free bytes is called
-** a fragment. The total number of bytes in all fragments is recorded.
-** in the page header at offset 7.
-**
-** SIZE DESCRIPTION
-** 2 Byte offset of the next freeblock
-** 2 Bytes in this freeblock
-**
-** Cells are of variable length. Cells are stored in the cell content area at
-** the end of the page. Pointers to the cells are in the cell pointer array
-** that immediately follows the page header. Cells is not necessarily
-** contiguous or in order, but cell pointers are contiguous and in order.
-**
-** Cell content makes use of variable length integers. A variable
-** length integer is 1 to 9 bytes where the lower 7 bits of each
-** byte are used. The integer consists of all bytes that have bit 8 set and
-** the first byte with bit 8 clear. The most significant byte of the integer
-** appears first. A variable-length integer may not be more than 9 bytes long.
-** As a special case, all 8 bytes of the 9th byte are used as data. This
-** allows a 64-bit integer to be encoded in 9 bytes.
-**
-** 0x00 becomes 0x00000000
-** 0x7f becomes 0x0000007f
-** 0x81 0x00 becomes 0x00000080
-** 0x82 0x00 becomes 0x00000100
-** 0x80 0x7f becomes 0x0000007f
-** 0x8a 0x91 0xd1 0xac 0x78 becomes 0x12345678
-** 0x81 0x81 0x81 0x81 0x01 becomes 0x10204081
-**
-** Variable length integers are used for rowids and to hold the number of
-** bytes of key and data in a btree cell.
-**
-** The content of a cell looks like this:
-**
-** SIZE DESCRIPTION
-** 4 Page number of the left child. Omitted if leaf flag is set.
-** var Number of bytes of data. Omitted if the zerodata flag is set.
-** var Number of bytes of key. Or the key itself if intkey flag is set.
-** * Payload
-** 4 First page of the overflow chain. Omitted if no overflow
-**
-** Overflow pages form a linked list. Each page except the last is completely
-** filled with data (pagesize - 4 bytes). The last page can have as little
-** as 1 byte of data.
-**
-** SIZE DESCRIPTION
-** 4 Page number of next overflow page
-** * Data
-**
-** Freelist pages come in two subtypes: trunk pages and leaf pages. The
-** file header points to the first in a linked list of trunk page. Each trunk
-** page points to multiple leaf pages. The content of a leaf page is
-** unspecified. A trunk page looks like this:
-**
-** SIZE DESCRIPTION
-** 4 Page number of next trunk page
-** 4 Number of leaf pointers on this page
-** * zero or more pages numbers of leaves

-** This routine is call to handle SQL of the following forms:
-**
-** insert into TABLE (IDLIST) values(EXPRLIST)
-** insert into TABLE (IDLIST) select
-**
-** The IDLIST following the table name is always optional. If omitted,
-** then a list of all columns for the table is substituted. The IDLIST
-** appears in the pColumn parameter. pColumn is NULL if IDLIST is omitted.
-**
-** The pList parameter holds EXPRLIST in the first form of the INSERT
-** statement above, and pSelect is NULL. For the second form, pList is
-** NULL and pSelect is a pointer to the select statement used to generate
-** data for the insert.
-**
-** The code generated follows one of four templates. For a simple
-** select with data coming from a VALUES clause, the code executes
-** once straight down through. The template looks like this:
-**
-** open write cursor to <table> and its indices
-** puts VALUES clause expressions onto the stack
-** write the resulting record into <table>
-** cleanup
-**
-** The three remaining templates assume the statement is of the form
-**
-** INSERT INTO <table> SELECT ...
-**
-** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
-** in other words if the SELECT pulls all columns from a single table
-** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
-** if <table2> and <table1> are distinct tables but have identical
-** schemas, including all the same indices, then a special optimization
-** is invoked that copies raw records from <table2> over to <table1>.
-** See the xferOptimization() function for the implementation of this
-** template. This is the second template.
-**
-** open a write cursor to <table>
-** open read cursor on <table2>
-** transfer all records in <table2> over to <table>
-** close cursors
-** foreach index on <table>
-** open a write cursor on the <table> index
-** open a read cursor on the corresponding <table2> index
-** transfer all records from the read to the write cursors
-** close cursors
-** end foreach
-**
-** The third template is for when the second template does not apply
-** and the SELECT clause does not read from <table> at any time.
-** The generated code follows this template:
-**
-** goto B
-** A: setup for the SELECT
-** loop over the rows in the SELECT
-** gosub C
-** end loop
-** cleanup after the SELECT
-** goto D
-** B: open write cursor to <table> and its indices
-** goto A
-** C: insert the select result into <table>
-** return
-** D: cleanup
-**
-** The fourth template is used if the insert statement takes its
-** values from a SELECT but the data is being inserted into a table
-** that is also read as part of the SELECT. In the third form,
-** we have to use a intermediate table to store the results of
-** the select. The template is like this:
-**
-** goto B
-** A: setup for the SELECT
-** loop over the tables in the SELECT
-** gosub C
-** end loop
-** cleanup after the SELECT
-** goto D
-** C: insert the select result into the intermediate table
-** return
-** B: open a cursor to an intermediate table
-** goto A
-** D: open write cursor to <table> and its indices
-** loop over the intermediate table
-** transfer values form intermediate table into <table>
-** end the loop
-** cleanup

-** Generate code to do constraint checks prior to an INSERT or an UPDATE.
-**
-** The input is a range of consecutive registers as follows:
-**
-** 1. The rowid of the row to be updated before the update. This
-** value is omitted unless we are doing an UPDATE that involves a
-** change to the record number or writing to a virtual table.
-**
-** 2. The rowid of the row after the update.
-**
-** 3. The data in the first column of the entry after the update.
-**
-** i. Data from middle columns...
-**
-** N. The data in the last column of the entry after the update.
-**
-** The regRowid parameter is the index of the register containing (2).
-**
-** The old rowid shown as entry (1) above is omitted unless both isUpdate
-** and rowidChng are 1. isUpdate is true for UPDATEs and false for
-** INSERTs. RowidChng means that the new rowid is explicitly specified by
-** the update or insert statement. If rowidChng is false, it means that
-** the rowid is computed automatically in an insert or that the rowid value
-** is not modified by the update.
-**
-** The code generated by this routine store new index entries into
-** registers identified by aRegIdx[]. No index entry is created for
-** indices where aRegIdx[i]==0. The order of indices in aRegIdx[] is
-** the same as the order of indices on the linked list of indices
-** attached to the table.
-**
-** This routine also generates code to check constraints. NOT NULL,
-** CHECK, and UNIQUE constraints are all checked. If a constraint fails,
-** then the appropriate action is performed. There are five possible
-** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
-**
-** Constraint type Action What Happens
-** --------------- ---------- ----------------------------------------
-** any ROLLBACK The current transaction is rolled back and
-** sqlite3_exec() returns immediately with a
-** return code of SQLITE_CONSTRAINT.
-**
-** any ABORT Back out changes from the current command
-** only (do not do a complete rollback) then
-** cause sqlite3_exec() to return immediately
-** with SQLITE_CONSTRAINT.
-**
-** any FAIL Sqlite_exec() returns immediately with a
-** return code of SQLITE_CONSTRAINT. The
-** transaction is not rolled back and any
-** prior changes are retained.
-**
-** any IGNORE The record number and data is popped from
-** the stack and there is an immediate jump
-** to label ignoreDest.
-**
-** NOT NULL REPLACE The NULL value is replace by the default
-** value for that column. If the default value
-** is NULL, the action is the same as ABORT.
-**
-** UNIQUE REPLACE The other row that conflicts with the row
-** being inserted is removed.
-**
-** CHECK REPLACE Illegal. The results in an exception.
-**
-** Which action to take is determined by the overrideError parameter.
-** Or if overrideError==OE_Default, then the pParse->onError parameter
-** is used. Or if pParse->onError==OE_Default then the onError value
-** for the constraint is used.
-**
-** The calling routine must open a read/write cursor for pTab with
-** cursor number "baseCur". All indices of pTab must also have open
-** read/write cursors with cursor number baseCur+i for the i-th cursor.
-** Except, if there is no possibility of a REPLACE action then
-** cursors do not need to be open for indices where aRegIdx[i]==0.

-** File Locking Notes: (Mostly about windows but also some info for Unix)
-**
-** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
-** those functions are not available. So we use only LockFile() and
-** UnlockFile().
-**
-** LockFile() prevents not just writing but also reading by other processes.
-** A SHARED_LOCK is obtained by locking a single randomly-chosen
-** byte out of a specific range of bytes. The lock byte is obtained at
-** random so two separate readers can probably access the file at the
-** same time, unless they are unlucky and choose the same lock byte.
-** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
-** There can only be one writer. A RESERVED_LOCK is obtained by locking
-** a single byte of the file that is designated as the reserved lock byte.
-** A PENDING_LOCK is obtained by locking a designated byte different from
-** the RESERVED_LOCK byte.
-**
-** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
-** which means we can use reader/writer locks. When reader/writer locks
-** are used, the lock is placed on the same range of bytes that is used
-** for probabilistic locking in Win95/98/ME. Hence, the locking scheme
-** will support two or more Win95 readers or two or more WinNT readers.
-** But a single Win95 reader will lock out all WinNT readers and a single
-** WinNT reader will lock out all other Win95 readers.
-**
-** The following #defines specify the range of bytes used for locking.
-** SHARED_SIZE is the number of bytes available in the pool from which
-** a random byte is selected for a shared lock. The pool of bytes for
-** shared locks begins at SHARED_FIRST.
-**
-** These #defines are available in sqlite_aux.h so that adaptors for
-** connecting SQLite to other operating systems can use the same byte
-** ranges for locking. In particular, the same locking strategy and
-** byte ranges are used for Unix. This leaves open the possiblity of having
-** clients on win95, winNT, and unix all talking to the same shared file
-** and all locking correctly. To do so would require that samba (or whatever
-** tool is being used for file sharing) implements locks correctly between
-** windows and unix. I'm guessing that isn't likely to happen, but by
-** using the same locking range we are at least open to the possibility.
-**
-** Locking in windows is manditory. For this reason, we cannot store
-** actual data in the bytes used for locking. The pager never allocates
-** the pages involved in locking therefore. SHARED_SIZE is selected so
-** that all locks will fit on a single page even at the minimum page size.
-** PENDING_BYTE defines the beginning of the locks. By default PENDING_BYTE
-** is set high so that we don't have to allocate an unused page except
-** for very large databases. But one should test the page skipping logic
-** by setting PENDING_BYTE low and running the entire regression suite.
-**
-** Changing the value of PENDING_BYTE results in a subtly incompatible
-** file format. Depending on how it is changed, you might not notice
-** the incompatibility right away, even running a full regression test.
-** The default location of PENDING_BYTE is the first byte past the
-** 1GB boundary.

-** Here is the dirt on POSIX advisory locks: ANSI STD 1003.1 (1996)
-** section 6.5.2.2 lines 483 through 490 specify that when a process
-** sets or clears a lock, that operation overrides any prior locks set
-** by the same process. It does not explicitly say so, but this implies
-** that it overrides locks set by the same process using a different
-** file descriptor. Consider this test case:
-**
-** int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
-** int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
-**
-** Suppose ./file1 and ./file2 are really the same file (because
-** one is a hard or symbolic link to the other) then if you set
-** an exclusive lock on fd1, then try to get an exclusive lock
-** on fd2, it works. I would have expected the second lock to
-** fail since there was already a lock on the file due to fd1.
-** But not so. Since both locks came from the same process, the
-** second overrides the first, even though they were on different
-** file descriptors opened on different file names.
-**
-** Bummer. If you ask me, this is broken. Badly broken. It means
-** that we cannot use POSIX locks to synchronize file access among
-** competing threads of the same process. POSIX locks will work fine
-** to synchronize access for threads in separate processes, but not
-** threads within the same process.
-**
-** To work around the problem, SQLite has to manage file locks internally
-** on its own. Whenever a new database is opened, we have to find the
-** specific inode of the database file (the inode is determined by the
-** st_dev and st_ino fields of the stat structure that fstat() fills in)
-** and check for locks already existing on that inode. When locks are
-** created or removed, we have to look at our own internal record of the
-** locks to see if another thread has previously set a lock on that same
-** inode.
-**
-** The sqlite3_file structure for POSIX is no longer just an integer file
-** descriptor. It is now a structure that holds the integer file
-** descriptor and a pointer to a structure that describes the internal
-** locks on the corresponding inode. There is one locking structure
-** per inode, so if the same inode is opened twice, both unixFile structures
-** point to the same locking structure. The locking structure keeps
-** a reference count (so we will know when to delete it) and a "cnt"
-** field that tells us its internal lock status. cnt==0 means the
-** file is unlocked. cnt==-1 means the file has an exclusive lock.
-** cnt>0 means there are cnt shared locks on the file.
-**
-** Any attempt to lock or unlock a file first checks the locking
-** structure. The fcntl() system call is only invoked to set a
-** POSIX lock if the internal lock structure transitions between
-** a locked and an unlocked state.
-**
-** 2004-Jan-11:
-** More recent discoveries about POSIX advisory locks. (The more
-** I discover, the more I realize the a POSIX advisory locks are
-** an abomination.)
-**
-** If you close a file descriptor that points to a file that has locks,
-** all locks on that file that are owned by the current process are
-** released. To work around this problem, each unixFile structure contains
-** a pointer to an openCnt structure. There is one openCnt structure
-** per open inode, which means that multiple unixFile can point to a single
-** openCnt. When an attempt is made to close an unixFile, if there are
-** other unixFile open on the same inode that are holding locks, the call
-** to close() the file descriptor is deferred until all of the locks clear.
-** The openCnt structure keeps a list of file descriptors that need to
-** be closed and that list is walked (and cleared) when the last lock
-** clears.
-**
-** First, under Linux threads, because each thread has a separate
-** process ID, lock operations in one thread do not override locks
-** to the same file in other threads. Linux threads behave like
-** separate processes in this respect. But, if you close a file
-** descriptor in linux threads, all locks are cleared, even locks
-** on other threads and even though the other threads have different
-** process IDs. Linux threads is inconsistent in this respect.
-** (I'm beginning to think that linux threads is an abomination too.)
-** The consequence of this all is that the hash table for the lockInfo
-** structure has to include the process id as part of its key because
-** locks in different threads are treated as distinct. But the
-** openCnt structure should not include the process id in its
-** key because close() clears lock on all threads, not just the current
-** thread. Were it not for this goofiness in linux threads, we could
-** combine the lockInfo and openCnt structures into a single structure.
-**
-** 2004-Jun-28:
-** On some versions of linux, threads can override each others locks.
-** On others not. Sometimes you can change the behavior on the same
-** system by setting the LD_ASSUME_KERNEL environment variable. The
-** POSIX standard is silent as to which behavior is correct, as far
-** as I can tell, so other versions of unix might show the same
-** inconsistency. There is no little doubt in my mind that posix
-** advisory locks and linux threads are profoundly broken.
-**
-** To work around the inconsistencies, we have to test at runtime
-** whether or not threads can override each others locks. This test
-** is run once, the first time any lock is attempted. A static
-** variable is set to record the results of this test for future

- ** confusion with SQLite lock names). The algorithms are complicated
- ** slightly in order to be compatible with windows systems simultaneously
- ** accessing the same database file, in case that is ever required.
- **
- ** Symbols defined in os.h indentify the 'pending byte' and the 'reserved
- ** byte', each single bytes at well known offsets, and the 'shared byte
- ** range', a range of 510 bytes at a well known offset.
- **
- ** To obtain a SHARED lock, a read-lock is obtained on the 'pending
- ** byte'. If this is successful, a random byte from the 'shared byte
- ** range' is read-locked and the lock on the 'pending byte' released.
- **
- ** A process may only obtain a RESERVED lock after it has a SHARED lock.
- ** A RESERVED lock is implemented by grabbing a write-lock on the
- ** 'reserved byte'.
- **
- ** A process may only obtain a PENDING lock after it has obtained a
- ** SHARED lock. A PENDING lock is implemented by obtaining a write-lock
- ** on the 'pending byte'. This ensures that no new SHARED locks can be
- ** obtained, but existing SHARED locks are allowed to persist. A process
- ** does not have to obtain a RESERVED lock on the way to a PENDING lock.
- ** This property is used by the algorithm for rolling back a journal file
- ** after a crash.
- **
- ** An EXCLUSIVE lock, obtained after a PENDING lock is held, is
- ** implemented by obtaining a write-lock on the entire 'shared byte
- ** range'. Since all other locks require a read-lock on one of the bytes
- ** within this range, this ensures that no other locks are held on the
- ** database.
- **

-** A Note About Memory Allocation:
-**
-** This driver uses malloc()/free() directly rather than going through
-** the SQLite-wrappers sqlite3_malloc()/sqlite3_free(). Those wrappers
-** are designed for use on embedded systems where memory is scarce and
-** malloc failures happen frequently. Win32 does not typically run on
-** embedded systems, and when it does the developers normally have bigger
-** problems to worry about than running out of memory. So there is not
-** a compelling need to use the wrappers.
-**
-** But there is a good reason to not use the wrappers. If we use the
-** wrappers then we will get simulated malloc() failures within this
-** driver. And that causes all kinds of problems for our tests. We
-** could enhance SQLite to deal with simulated malloc failures within
-** the OS driver, but the code to deal with those failure would not
-** be exercised on Linux (which does not need to malloc() in the driver)
-** and so we would have difficulty writing coverage tests for that
-** code. Better to leave the code out, we think.
-**
-** The point of this discussion is as follows: When creating a new
-** OS layer for an embedded system, if you use this file as an example,
-** avoid the use of malloc()/free(). Those routines work ok on windows
-** desktops but not so well in embedded systems.

-**
-** PAGER_SHARED The page cache is reading the database.
-** Writing is not permitted. There can be

-**
-** PAGER_RESERVED This process has reserved the database for writing
-** but has not yet made any changes. Only one process
-** at a time can reserve the database. The original
-** database file has not been modified so other
-** processes may still be reading the on-disk

-**
-** PAGER_EXCLUSIVE The page cache is writing the database.
-** Access is exclusive. No other processes or

-** process is writing.

-** PAGER_SYNCED The pager moves to this state from PAGER_EXCLUSIVE
-** after all dirty pages have been written to the
-** database file and the file has been synced to
-** disk. All that remains to do is to remove or
-** truncate the journal file and the transaction
-** will be committed.

-** PAGER_RESERVED. (Note that sqlite3PagerWrite() can only be
-** called on an outstanding page which means that the pager must
-** be in PAGER_SHARED before it transitions to PAGER_RESERVED.)
-** PAGER_RESERVED means that there is an open rollback journal.
-** The transition to PAGER_EXCLUSIVE occurs before any changes
-** are made to the database file, though writes to the rollback

-** Client code should call sqlite3PagerWrite() on a page prior to making
-** any modifications to that page. The first time sqlite3PagerWrite()
-** is called, the original page contents are written into the rollback
-** journal and PgHdr.inJournal and PgHdr.needSync are set. Later, once
-** the journal page has made it onto the disk surface, PgHdr.needSync
-** is cleared. The modified page cannot be written back into the original
-** database file until the journal pages has been synced to disk and the
-** PgHdr.needSync has been cleared.
-**
-** The PgHdr.dirty flag is set when sqlite3PagerWrite() is called and
-** is cleared again when the page content is written back to the original
-** database file.
-**
-** Details of important structure elements:
-**
-** needSync
-**
-** If this is true, this means that it is not safe to write the page
-** content to the database because the original content needed
-** for rollback has not by synced to the main rollback journal.
-** The original content may have been written to the rollback journal
-** but it has not yet been synced. So we cannot write to the database
-** file because power failure might cause the page in the journal file
-** to never reach the disk. It is as if the write to the journal file
-** does not occur until the journal file is synced.
-**
-** This flag is false if the page content exactly matches what
-** currently exists in the database file. The needSync flag is also
-** false if the original content has been written to the main rollback
-** journal and synced. If the page represents a new page that has
-** been added onto the end of the database during the current
-** transaction, the needSync flag is true until the original database
-** size in the journal header has been synced to disk.
-**
-** inJournal
-**
-** This is true if the original page has been written into the main
-** rollback journal. This is always false for new pages added to
-** the end of the database file during the current transaction.
-** And this flag says nothing about whether or not the journal
-** has been synced to disk. For pages that are in the original
-** database file, the following expression should always be true:
-**
-** inJournal = (pPager->aInJournal[(pgno-1)/8] & (1<<((pgno-1)%8))!=0
-**
-** The pPager->aInJournal[] array is only valid for the original
-** pages of the database, not new pages that are added to the end
-** of the database, so obviously the above expression cannot be
-** valid for new pages. For new pages inJournal is always 0.
-**
-** dirty
-**
-** When true, this means that the content of the page has been
-** modified and needs to be written back to the database file.
-** If false, it means that either the content of the page is
-** unchanged or else the content is unimportant and we do not
-** care whether or not it is preserved.
-**
-** alwaysRollback
-**
-** This means that the sqlite3PagerDontRollback() API should be
-** ignored for this page. The DontRollback() API attempts to say
-** that the content of the page on disk is unimportant (it is an
-** unused page on the freelist) so that it is unnecessary to
-** rollback changes to this page because the content of the page
-** can change without changing the meaning of the database. This
-** flag overrides any DontRollback() attempt. This flag is set
-** when a page that originally contained valid data is added to
-** the freelist. Later in the same transaction, this page might
-** be pulled from the freelist and reused for something different
-** and at that point the DontRollback() API will be called because
-** pages taken from the freelist do not need to be protected by
-** the rollback journal. But this flag says that the page was
-** not originally part of the freelist so that it still needs to
-** be rolled back in spite of any subsequent DontRollback() calls.
-**
-** needRead
-**
-** This flag means (when true) that the content of the page has
-** not yet been loaded from disk. The in-memory content is just
-** garbage. (Actually, we zero the content, but you should not
-** make any assumptions about the content nevertheless.) If the
-** content is needed in the future, it should be read from the
-** original database file.

-** table.
-** YYFALLBACK If defined, this indicates that one or more tokens
-** have fall-back values which should be used if the
-** original value of the token will not parse.
-** YYACTIONTYPE is the data type used for storing terminal
-** and nonterminal numbers. "unsigned char" is
-** used if there are fewer than 250 rules and
-** states combined. "int" is used otherwise.
-** sqlite3ParserTOKENTYPE is the data type used for minor tokens given

-** YYMINORTYPE is the data type used for all minor tokens.
-** This is typically a union of many types, one of

-/* Next are that tables used to determine what action to take based on the
-** current state and lookahead token. These tables are used to implement
-** functions that take a state number and lookahead value and return an
-** action integer.
-**
-** Suppose the action integer is N. Then the action is determined as
-** follows
-**
-** 0 <= N < YYNSTATE Shift N. That is, push the lookahead
-** token onto the stack and goto state N.
-**
-** YYNSTATE <= N < YYNSTATE+YYNRULE Reduce by rule N-YYNSTATE.
-**
-** N == YYNSTATE+YYNRULE A syntax error has occurred.
-**
-** N == YYNSTATE+YYNRULE+1 The parser accepts its input.
-**
-** N == YYNSTATE+YYNRULE+2 No such action. Denotes unused
-** slots in the yy_action[] table.
-**
-** The action table is constructed as a single large table named yy_action[].
-** Given state S and lookahead X, the action is computed as
-**
-** yy_action[ yy_shift_ofst[S] + X ]
-**
-** If the index value yy_shift_ofst[S]+X is out of range or if the value
-** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
-** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
-** and that yy_default[S] should be used instead.
-**
-** The formula above is for computing the action when the lookahead is
-** a terminal symbol. If the lookahead is a non-terminal (as occurs after
-** a reduce action) then the yy_reduce_ofst[] array is used in place of
-** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
-** YY_SHIFT_USE_DFLT.
-**
-** The following are the tables generated in this section:
-**
-** yy_action[] A single table containing all actions.
-** yy_lookahead[] A table containing the lookahead for each entry in
-** yy_action. Used to detect hash collisions.
-** yy_shift_ofst[] For each state, the offset into yy_action for
-** shifting terminals.
-** yy_reduce_ofst[] For each state, the offset into yy_action for
-** shifting non-terminals after a reduce.
-** yy_default[] Default action for each state.

-** The "printf" code that follows dates from the 1980's. It is in
-** the public domain. The original comments are included here for
-** completeness. They are very out-of-date but might be useful as
-** an historical reference. Most of the "enhancements" have been backed
-** out so that the functionality is now the same as standard printf().
-**
-**************************************************************************
-**
-** The following modules is an enhanced replacement for the "printf" subroutines
-** found in the standard C library. The following enhancements are
-** supported:
-**
-** + Additional functions. The standard set of "printf" functions
-** includes printf, fprintf, sprintf, vprintf, vfprintf, and
-** vsprintf. This module adds the following:
-**
-** * snprintf -- Works like sprintf, but has an extra argument
-** which is the size of the buffer written to.
-**
-** * mprintf -- Similar to sprintf. Writes output to memory
-** obtained from malloc.
-**
-** * xprintf -- Calls a function to dispose of output.
-**
-** * nprintf -- No output, but returns the number of characters
-** that would have been output by printf.
-**
-** * A v- version (ex: vsnprintf) of every function is also
-** supplied.
-**
-** + A few extensions to the formatting notation are supported:
-**
-** * The "=" flag (similar to "-") causes the output to be
-** be centered in the appropriately sized field.
-**
-** * The %b field outputs an integer in binary notation.
-**
-** * The %c field now accepts a precision. The character output
-** is repeated by the number of times the precision specifies.
-**
-** * The %' field works like %c, but takes as its character the
-** next character of the format string, instead of the next
-** argument. For example, printf("%.78'-") prints 78 minus
-** signs, the same as printf("%.78c",'-').
-**
-** + When compiled using GCC on a SPARC, this version of printf is
-** faster than the library printf for SUN OS 4.1.
-**
-** + All functions are fully reentrant.

-** This routine attempts to flatten subqueries in order to speed
-** execution. It returns 1 if it makes changes and 0 if no flattening
-** occurs.
-**
-** To understand the concept of flattening, consider the following
-** query:
-**
-** SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
-**
-** The default way of implementing this query is to execute the
-** subquery first and store the results in a temporary table, then
-** run the outer query on that temporary table. This requires two
-** passes over the data. Furthermore, because the temporary table
-** has no indices, the WHERE clause on the outer query cannot be
-** optimized.
-**
-** This routine attempts to rewrite queries such as the above into
-** a single flat select, like this:
-**
-** SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
-**
-** The code generated for this simpification gives the same result
-** but only has to scan the data once. And because indices might
-** exist on the table t1, a complete scan of the data might be
-** avoided.
-**
-** Flattening is only attempted if all of the following are true:
-**
-** (1) The subquery and the outer query do not both use aggregates.
-**
-** (2) The subquery is not an aggregate or the outer query is not a join.
-**
-** (3) The subquery is not the right operand of a left outer join, or
-** the subquery is not itself a join. (Ticket #306)
-**
-** (4) The subquery is not DISTINCT or the outer query is not a join.
-**
-** (5) The subquery is not DISTINCT or the outer query does not use
-** aggregates.
-**
-** (6) The subquery does not use aggregates or the outer query is not
-** DISTINCT.
-**
-** (7) The subquery has a FROM clause.
-**
-** (8) The subquery does not use LIMIT or the outer query is not a join.
-**
-** (9) The subquery does not use LIMIT or the outer query does not use
-** aggregates.
-**
-** (10) The subquery does not use aggregates or the outer query does not
-** use LIMIT.
-**
-** (11) The subquery and the outer query do not both have ORDER BY clauses.
-**
-** (12) The subquery is not the right term of a LEFT OUTER JOIN or the
-** subquery has no WHERE clause. (added by ticket #350)
-**
-** (13) The subquery and outer query do not both use LIMIT
-**
-** (14) The subquery does not use OFFSET
-**
-** (15) The outer query is not part of a compound select or the
-** subquery does not have both an ORDER BY and a LIMIT clause.
-** (See ticket #2339)
-**
-** In this routine, the "p" parameter is a pointer to the outer query.
-** The subquery is p->pSrc->a[iFrom]. isAgg is true if the outer query
-** uses aggregates and subqueryIsAgg is true if the subquery uses aggregates.
-**
-** If flattening is not attempted, this routine is a no-op and returns 0.
-** If flattening is attempted this routine returns 1.
-**
-** All of the expression analysis must occur on both the outer query and
-** the subquery before this routine runs.

-** contents of the SelectDest structure pointed to by argument pDest
-** as follows:
-**
-** pDest->eDest Result
-** ------------ -------------------------------------------
-** SRT_Callback Invoke the callback for each row of the result.
-**
-** SRT_Mem Store first result in memory cell pDest->iParm
-**
-** SRT_Set Store non-null results as keys of table pDest->iParm.
-** Apply the affinity pDest->affinity before storing them.
-**
-** SRT_Union Store results as a key in a temporary table pDest->iParm.
-**
-** SRT_Except Remove results from the temporary table pDest->iParm.
-**
-** SRT_Table Store results in temporary table pDest->iParm
-**
-** SRT_EphemTab Create an temporary table pDest->iParm and store
-** the result there. The cursor is left open after
-** returning.
-**
-** SRT_Subroutine For each row returned, push the results onto the
-** vdbe stack and call the subroutine (via OP_Gosub)
-** at address pDest->iParm.
-**
-** SRT_Exists Store a 1 in memory cell pDest->iParm if the result
-** set is not empty.
-**
-** SRT_Discard Throw the results away.
-**
-** See the selectInnerLoop() function for a canonical listing of the
-** allowed values of eDest and their meanings.
-**
-** This routine returns the number of errors. If any errors are
-** encountered, then an appropriate error message is left in
-** pParse->zErrMsg.
-**
-** This routine does NOT free the Select structure passed in. The
-** calling function needs to do that.
-**
-** The pParent, parentTab, and *pParentAgg fields are filled in if this
-** SELECT is a subquery. This routine may try to combine this SELECT
-** with its parent to form a single flat query. In so doing, it might
-** change the parent query from a non-aggregate to an aggregate query.
-** For that reason, the pParentAgg flag is passed as a pointer, so it
-** can be changed.
-**
-** Example 1: The meaning of the pParent parameter.
-**
-** SELECT * FROM t1 JOIN (SELECT x, count(*) FROM t2) JOIN t3;
-** \ \_______ subquery _______/ /
-** \ /
-** \____________________ outer query ___________________/
-**
-** This routine is called for the outer query first. For that call,
-** pParent will be NULL. During the processing of the outer query, this
-** routine is called recursively to handle the subquery. For the recursive
-** call, pParent will point to the outer query. Because the subquery is
-** the second element in a three-way join, the parentTab parameter will
-** be 1 (the 2nd value of a 0-indexed array.)

-**
-** The iVersion field is initially 1 but may be larger for future

-**
-** The szOsFile field is the size of the subclassed [sqlite3_file]

-**
-** Registered vfs modules are kept on a linked list formed by
-** the pNext pointer. The [sqlite3_vfs_register()]
-** and [sqlite3_vfs_unregister()] interfaces manage this list
-** in a thread-safe way. The [sqlite3_vfs_find()] interface
-** searches the list.
-**
-** The pNext field is the only fields in the sqlite3_vfs
-** structure that SQLite will ever modify. SQLite will only access
-** or modify this field while holding a particular static mutex.
-** The application should never modify anything within the sqlite3_vfs
-** object once the object has been registered.
-**
-** The zName field holds the name of the VFS module. The name must
-** be unique across all VFS modules.
-**
-** {F11141} SQLite will guarantee that the zFilename string passed to
-** xOpen() is a full pathname as generated by xFullPathname() and
-** that the string will be valid and unchanged until xClose() is
-** called. {END} So the [sqlite3_file] can store a pointer to the
-** filename if it needs to remember the filename for some reason.
-**

-** or [sqlite3_open16()] is used, then flags includes at least
-** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]. {END}
-** If xOpen() opens a file read-only then it sets *pOutFlags to
-** include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be
-** set.
-**
-** {F11143} SQLite will also add one of the following flags to the xOpen()

-** The file I/O implementation can use the object type flags to
-** changes the way it deals with files. For example, an application

-** and set up its I/O subsystem accordingly.

-** <li> [SQLITE_OPEN_DELETEONCLOSE]
-** <li> [SQLITE_OPEN_EXCLUSIVE]
-** </ul>
-**

-** for the main database file. {END}
-**
-** {F11148} At least szOsFile bytes of memory is allocated by SQLite
-** to hold the [sqlite3_file] structure passed as the third
-** argument to xOpen. {END} The xOpen method does not have to
-** allocate the structure; it should just fill it in.
-**
-** {F11149} The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
-** to test for the existance of a file,
-** or [SQLITE_ACCESS_READWRITE] to test to see
-** if a file is readable and writable, or [SQLITE_ACCESS_READ]

-** CAPI3REF: Register A Callback To Handle SQLITE_BUSY Errors {F12310}
-**
-** This routine identifies a callback function that might be
-** invoked whenever an attempt is made to open a database table
-** that another thread or process has locked.
-** If the busy callback is NULL, then [SQLITE_BUSY]
-** or [SQLITE_IOERR_BLOCKED]
-** is returned immediately upon encountering the lock.
-** If the busy callback is not NULL, then the
-** callback will be invoked with two arguments. The
-** first argument to the handler is a copy of the void* pointer which
-** is the third argument to this routine. The second argument to
-** the handler is the number of times that the busy handler has
-** been invoked for this locking event. If the
-** busy callback returns 0, then no additional attempts are made to
-** access the database and [SQLITE_BUSY] or [SQLITE_IOERR_BLOCKED] is returned.
-** If the callback returns non-zero, then another attempt
-** is made to open the database for reading and the cycle repeats.
-**
-** The presence of a busy handler does not guarantee that
-** it will be invoked when there is lock contention.
-** If SQLite determines that invoking the busy handler could result in
-** a deadlock, it will go ahead and return [SQLITE_BUSY] or
-** [SQLITE_IOERR_BLOCKED] instead of invoking the
-** busy handler.
-** Consider a scenario where one process is holding a read lock that
-** it is trying to promote to a reserved lock and
-** a second process is holding a reserved lock that it is trying
-** to promote to an exclusive lock. The first process cannot proceed
-** because it is blocked by the second and the second process cannot
-** proceed because it is blocked by the first. If both processes
-** invoke the busy handlers, neither will make any progress. Therefore,
-** SQLite returns [SQLITE_BUSY] for the first process, hoping that this
-** will induce the first process to release its read lock and allow
-** the second process to proceed.
-**
-** The default busy callback is NULL.
-**
-** The [SQLITE_BUSY] error is converted to [SQLITE_IOERR_BLOCKED]
-** when SQLite is in the middle of a large transaction where all the
-** changes will not fit into the in-memory cache. SQLite will
-** already hold a RESERVED lock on the database file, but it needs
-** to promote this lock to EXCLUSIVE so that it can spill cache
-** pages into the database file without harm to concurrent
-** readers. If it is unable to promote the lock, then the in-memory
-** cache will be left in an inconsistent state and so the error
-** code is promoted from the relatively benign [SQLITE_BUSY] to
-** the more severe [SQLITE_IOERR_BLOCKED]. This error code promotion
-** forces an automatic rollback of the changes. See the
-** <a href="http://www.sqlite.org/cvstrac/wiki?p=CorruptionFollowingBusyError">
-** CorruptionFollowingBusyError</a> wiki page for a discussion of why
-** this is important.

-** CAPI3REF: Convenience Routines For Running Queries {F12370}
-**
-** Definition: A <b>result table</b> is memory data structure created by the
-** [sqlite3_get_table()] interface. A result table records the
-** complete query results from one or more queries.
-**
-** The table conceptually has a number of rows and columns. But
-** these numbers are not part of the result table itself. These
-** numbers are obtained separately. Let N be the number of rows
-** and M be the number of columns.
-**
-** A result table is an array of pointers to zero-terminated
-** UTF-8 strings. There are (N+1)*M elements in the array.
-** The first M pointers point to zero-terminated strings that
-** contain the names of the columns.
-** The remaining entries all point to query results. NULL
-** values are give a NULL pointer. All other values are in
-** their UTF-8 zero-terminated string representation as returned by
-** [sqlite3_column_text()].
-**
-** A result table might consists of one or more memory allocations.
-** It is not safe to pass a result table directly to [sqlite3_free()].
-** A result table should be deallocated using [sqlite3_free_table()].
-**
-** As an example of the result table format, suppose a query result
-** is as follows:
-**
-** <blockquote><pre>
-** Name | Age
-** -----------------------
-** Alice | 43
-** Bob | 28
-** Cindy | 21
-** </pre></blockquote>
-**
-** There are two column (M==2) and three rows (N==3). Thus the
-** result table has 8 entries. Suppose the result table is stored
-** in an array names azResult. Then azResult holds this content:
-**
-** <blockquote><pre>
-** azResult[0] = "Name";
-** azResult[1] = "Age";
-** azResult[2] = "Alice";
-** azResult[3] = "43";
-** azResult[4] = "Bob";
-** azResult[5] = "28";
-** azResult[6] = "Cindy";
-** azResult[7] = "21";
-** </pre></blockquote>
-**
-** The sqlite3_get_table() function evaluates one or more
-** semicolon-separated SQL statements in the zero-terminated UTF-8
-** string of its 2nd parameter. It returns a result table to the
-** pointer given in its 3rd parameter.
-**
-** After the calling function has finished using the result, it should
-** pass the pointer to the result table to sqlite3_free_table() in order to
-** release the memory that was malloc-ed. Because of the way the
-** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
-** function must not try to call [sqlite3_free()] directly. Only
-** [sqlite3_free_table()] is able to release the memory properly and safely.
-**
-** The sqlite3_get_table() interface is implemented as a wrapper around
-** [sqlite3_exec()]. The sqlite3_get_table() routine does not have access
-** to any internal data structures of SQLite. It uses only the public
-** interface defined here. As a consequence, errors that occur in the
-** wrapper layer outside of the internal [sqlite3_exec()] call are not
-** reflected in subsequent calls to [sqlite3_errcode()] or
-** [sqlite3_errmsg()].

-** CAPI3REF: Formatted String Printing Functions {F17400}
-**
-** These routines are workalikes of the "printf()" family of functions
-** from the standard C library.
-**
-** The sqlite3_mprintf() and sqlite3_vmprintf() routines write their
-** results into memory obtained from [sqlite3_malloc()].
-** The strings returned by these two routines should be
-** released by [sqlite3_free()]. Both routines return a
-** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
-** memory to hold the resulting string.
-**
-** In sqlite3_snprintf() routine is similar to "snprintf()" from
-** the standard C library. The result is written into the
-** buffer supplied as the second parameter whose size is given by
-** the first parameter. Note that the order of the
-** first two parameters is reversed from snprintf(). This is an
-** historical accident that cannot be fixed without breaking
-** backwards compatibility. Note also that sqlite3_snprintf()
-** returns a pointer to its buffer instead of the number of
-** characters actually written into the buffer. We admit that
-** the number of characters written would be a more useful return
-** value but we cannot change the implementation of sqlite3_snprintf()
-** now without breaking compatibility.
-**
-** As long as the buffer size is greater than zero, sqlite3_snprintf()
-** guarantees that the buffer is always zero-terminated. The first
-** parameter "n" is the total size of the buffer, including space for
-** the zero terminator. So the longest string that can be completely
-** written will be n-1 characters.
-**
-** These routines all implement some additional formatting
-** options that are useful for constructing SQL statements.
-** All of the usual printf formatting options apply. In addition, there
-** is are "%q", "%Q", and "%z" options.
-**
-** The %q option works like %s in that it substitutes a null-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, so some string variable 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. Or if the parameter in the argument
-** list is a NULL pointer, %Q substitutes the text "NULL" (without single
-** quotes) in place of the %Q option. {END} 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 "%z" formatting option works exactly like "%s" with the
-** addition that after the string has been read and copied into
-** the result, [sqlite3_free()] is called on the input string. {END}

-**
-** The SQLite core uses these three routines for all of its own

-** a NULL pointer.
-**
-** Calling sqlite3_free() with a pointer previously returned
-** by sqlite3_malloc() or sqlite3_realloc() releases that memory so
-** that it might be reused. The sqlite3_free() routine is
-** a no-op if is called with a NULL pointer. Passing a NULL pointer
-** to sqlite3_free() is harmless. After being freed, memory
-** should neither be read nor written. Even reading previously freed
-** memory might result in a segmentation fault or other severe error.
-** Memory corruption, a segmentation fault, or other severe error
-** might result if sqlite3_free() is called with a non-NULL pointer that
-** was not obtained from sqlite3_malloc() or sqlite3_free().
-**

-** prior memory allocation to be at least N bytes, where N is the
-** second parameter. The memory allocation to be resized is the first
-** parameter. If the first parameter to sqlite3_realloc()
-** is a NULL pointer then its behavior is identical to calling

-** If the second parameter to sqlite3_realloc() is zero or
-** negative then the behavior is exactly the same as calling
-** sqlite3_free(P) where P is the first parameter to sqlite3_realloc().
-** Sqlite3_realloc() returns a pointer to a memory allocation
-** of at least N bytes in size or NULL if sufficient memory is unavailable.
-** If M is the size of the prior allocation, then min(N,M) bytes
-** of the prior allocation are copied into the beginning of buffer returned

-** CAPI3REF: Compile-Time Authorization Callbacks {F12500}
-**
-** This routine registers a authorizer callback with a particular

-** The authorizer callback is invoked as SQL statements are being compiled
-** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
-** [sqlite3_prepare16()] and [sqlite3_prepare16_v2()]. At various
-** points during the compilation process, as logic is being created
-** to perform various actions, the authorizer callback is invoked to
-** see if those actions are allowed. The authorizer callback should
-** return SQLITE_OK to allow the action, [SQLITE_IGNORE] to disallow the
-** specific action but allow the SQL statement to continue to be
-** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
-** rejected with an error. If the authorizer callback returns
-** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
-** then [sqlite3_prepare_v2()] or equivalent call that triggered
-** the authorizer will fail with an error message.
-**
-** When the callback returns [SQLITE_OK], that means the operation
-** requested is ok. When the callback returns [SQLITE_DENY], the
-** [sqlite3_prepare_v2()] or equivalent call that triggered the
-** authorizer will fail with an error message explaining that

-** and the callback returns [SQLITE_IGNORE] then the prepared
-** statement is constructed to insert a NULL value in place of
-** the table column that would have
-** been read if [SQLITE_OK] had been returned. The [SQLITE_IGNORE]
-** return can be used to deny an untrusted user access to individual
-** columns of a table.
-**
-** The first parameter to the authorizer callback is a copy of
-** the third parameter to the sqlite3_set_authorizer() interface.
-** The second parameter to the callback is an integer
-** [SQLITE_COPY | action code] that specifies the particular action
-** to be authorized. The third through sixth
-** parameters to the callback are zero-terminated strings that contain
-** additional details about the action to be authorized.
-**
-** An authorizer is used when preparing SQL statements from an untrusted
-** source, to ensure that the SQL statements do not try to access data
-** that they are not allowed to see, or that they do not try to
-** execute malicious statements that damage the database. For
-** example, an application may allow a user to enter arbitrary
-** SQL queries for evaluation by a database. But the application does
-** not want the user to be able to make arbitrary changes to the

-** CAPI3REF: Compiling An SQL Statement {F13010}
-**
-** To execute an SQL query, it must first be compiled into a byte-code
-** program using one of these routines.
-**
-** The first argument "db" is an [database connection]
-** obtained from a prior call to [sqlite3_open()], [sqlite3_open_v2()]
-** or [sqlite3_open16()].
-** The second argument "zSql" is the statement to be compiled, encoded
-** as either UTF-8 or UTF-16. The sqlite3_prepare() and sqlite3_prepare_v2()
-** interfaces uses UTF-8 and sqlite3_prepare16() and sqlite3_prepare16_v2()
-** use UTF-16. {END}
-**
-** If the nByte argument is less
-** than zero, then zSql is read up to the first zero terminator.
-** If nByte is non-negative, then it is the maximum number of
-** bytes read from zSql. When nByte is non-negative, the
-** zSql string ends at either the first '\000' or '\u0000' character or
-** until the nByte-th byte, whichever comes first. {END}
-**
-** *pzTail is made to point to the first byte past the end of the
-** first SQL statement in zSql. These routines only compiles the first
-** statement in zSql, so *pzTail is left pointing to what remains
-** uncompiled.
-**
-** *ppStmt is left pointing to a compiled [prepared statement] that can be
-** executed using [sqlite3_step()]. Or if there is an error, *ppStmt may be
-** set to NULL. If the input text contains no SQL (if the input
-** is and empty string or a comment) then *ppStmt is set to NULL.
-** {U13018} The calling procedure is responsible for deleting the
-** compiled SQL statement
-** using [sqlite3_finalize()] after it has finished with it.
-**
-** On success, [SQLITE_OK] is returned. Otherwise an
-** [error code] is returned.
-**
-** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
-** recommended for all new programs. The two older interfaces are retained
-** for backwards compatibility, but their use is discouraged.
-** In the "v2" interfaces, the prepared statement
-** that is returned (the [sqlite3_stmt] object) contains a copy of the
-** original SQL text. {END} This causes the [sqlite3_step()] interface to
-** behave a differently in two ways:
-**
-** <ol>
-** <li>
-** If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
-** always used to do, [sqlite3_step()] will automatically recompile the SQL
-** statement and try to run it again. If the schema has changed in
-** a way that makes the statement no longer valid, [sqlite3_step()] will still
-** return [SQLITE_SCHEMA]. But unlike the legacy behavior,
-** [SQLITE_SCHEMA] is now a fatal error. Calling
-** [sqlite3_prepare_v2()] again will not make the
-** error go away. Note: use [sqlite3_errmsg()] to find the text
-** of the parsing error that results in an [SQLITE_SCHEMA] return. {END}
-** </li>
-**
-** <li>
-** When an error occurs,
-** [sqlite3_step()] will return one of the detailed
-** [error codes] or [extended error codes].
-** The legacy behavior was that [sqlite3_step()] would only return a generic
-** [SQLITE_ERROR] result code and you would have to make a second call to
-** [sqlite3_reset()] in order to find the underlying cause of the problem.
-** With the "v2" prepare interfaces, the underlying reason for the error is

-** CAPI3REF: Binding Values To Prepared Statements {F13500}
-**
-** In the SQL strings input to [sqlite3_prepare_v2()] and its
-** variants, literals may be replace by a parameter in one
-** of these forms:
-**
-** <ul>
-** <li> ?
-** <li> ?NNN
-** <li> :VVV
-** <li> @VVV
-** <li> $VVV
-** </ul>
-**
-** In the parameter forms shown above NNN is an integer literal,
-** VVV alpha-numeric parameter name.
-** The values of these parameters (also called "host parameter names"
-** or "SQL parameters")
-** can be set using the sqlite3_bind_*() routines defined here.
-**
-** The first argument to the sqlite3_bind_*() routines always
-** is a pointer to the [sqlite3_stmt] object returned from
-** [sqlite3_prepare_v2()] or its variants. The second
-** argument is the index of the parameter to be set. The
-** first parameter has an index of 1. When the same named
-** parameter is used more than once, second and subsequent
-** occurrences have the same index as the first occurrence.
-** The index for named parameters can be looked up using the
-** [sqlite3_bind_parameter_name()] API if desired. The index
-** for "?NNN" parameters is the value of NNN.
-** The NNN value must be between 1 and the compile-time
-** parameter SQLITE_MAX_VARIABLE_NUMBER (default value: 999).
-**
-** The third argument is the value to bind to the parameter.
-**
-** In those
-** routines that have a fourth argument, its value is the number of bytes
-** in the parameter. To be clear: the value is the number of <u>bytes</u>
-** in the value, not the number of characters. The number
-** of bytes does not include the zero-terminator at the end of strings.
-** If the fourth parameter is negative, the length of the string is
-** number of bytes up to the first zero terminator.
-**
-** The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
-** sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
-** string after SQLite has finished with it. If the fifth argument is
-** the special value [SQLITE_STATIC], then SQLite assumes that the
-** information is in static, unmanaged space and does not need to be freed.
-** If the fifth argument has the value [SQLITE_TRANSIENT], then
-** SQLite makes its own private copy of the data immediately, before
-** the sqlite3_bind_*() routine returns.
-**
-** The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
-** is filled with zeros. A zeroblob uses a fixed amount of memory
-** (just an integer to hold it size) while it is being processed.
-** Zeroblobs are intended to serve as place-holders for BLOBs whose
-** content is later written using
-** [sqlite3_blob_open | increment BLOB I/O] routines. A negative
-** value for the zeroblob results in a zero-length BLOB.
-**
-** The sqlite3_bind_*() routines must be called after
-** [sqlite3_prepare_v2()] (and its variants) or [sqlite3_reset()] and
-** before [sqlite3_step()].
-** Bindings are not cleared by the [sqlite3_reset()] routine.
-** Unbound parameters are interpreted as NULL.
-**
-** These routines return [SQLITE_OK] on success or an error code if
-** anything goes wrong. [SQLITE_RANGE] is returned if the parameter
-** index is out of range. [SQLITE_NOMEM] is returned if malloc fails.
-** [SQLITE_MISUSE] might be returned if these routines are called on a
-** virtual machine that is the wrong state or which has already been finalized.
-** Detection of misuse is unreliable. Applications should not depend
-** on SQLITE_MISUSE returns. SQLITE_MISUSE is intended to indicate a
-** a logic error in the application. Future versions of SQLite might
-** panic rather than return SQLITE_MISUSE.

-** CAPI3REF: Evaluate An SQL Statement {F13200}
-**
-** After an [prepared statement] has been prepared with a call
-** to either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] or to one of
-** the legacy interfaces [sqlite3_prepare()] or [sqlite3_prepare16()],
-** then this function must be called one or more times to evaluate the
-** statement.
-**
-** The details of the behavior of this sqlite3_step() interface depend
-** on whether the statement was prepared using the newer "v2" interface
-** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy
-** interface [sqlite3_prepare()] and [sqlite3_prepare16()]. The use of the
-** new "v2" interface is recommended for new applications but the legacy
-** interface will continue to be supported.
-**
-** In the lagacy interface, the return value will be either [SQLITE_BUSY],
-** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
-** With the "v2" interface, any of the other [SQLITE_OK | result code]
-** or [SQLITE_IOERR_READ | extended result code] might be returned as
-** well.
-**
-** [SQLITE_BUSY] means that the database engine was unable to acquire the
-** database locks it needs to do its job. If the statement is a COMMIT
-** or occurs outside of an explicit transaction, then you can retry the
-** statement. If the statement is not a COMMIT and occurs within a
-** explicit transaction then you should rollback the transaction before
-** continuing.
-**
-** [SQLITE_DONE] means that the statement has finished executing
-** successfully. sqlite3_step() should not be called again on this virtual
-** machine without first calling [sqlite3_reset()] to reset the virtual
-** machine back to its initial state.
-**
-** If the SQL statement being executed returns any data, then
-** [SQLITE_ROW] is returned each time a new row of data is ready
-** for processing by the caller. The values may be accessed using
-** the [sqlite3_column_int | column access functions].
-** sqlite3_step() is called again to retrieve the next row of data.
-**
-** [SQLITE_ERROR] means that a run-time error (such as a constraint
-** violation) has occurred. sqlite3_step() should not be called again on
-** the VM. More information may be found by calling [sqlite3_errmsg()].
-** With the legacy interface, a more specific error code (example:
-** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
-** can be obtained by calling [sqlite3_reset()] on the
-** [prepared statement]. In the "v2" interface,
-** the more specific error code is returned directly by sqlite3_step().
-**
-** [SQLITE_MISUSE] means that the this routine was called inappropriately.
-** Perhaps it was called on a [prepared statement] that has
-** already been [sqlite3_finalize | finalized] or on one that had
-** previously returned [SQLITE_ERROR] or [SQLITE_DONE]. Or it could
-** be the case that the same database connection is being used by two or
-** more threads at the same moment in time.
-**
-** <b>Goofy Interface Alert:</b>
-** In the legacy interface,
-** the sqlite3_step() API always returns a generic error code,
-** [SQLITE_ERROR], following any error other than [SQLITE_BUSY]
-** and [SQLITE_MISUSE]. You must call [sqlite3_reset()] or
-** [sqlite3_finalize()] in order to find one of the specific
-** [error codes] that better describes the error.
-** We admit that this is a goofy design. The problem has been fixed
-** with the "v2" interface. If you prepare all of your SQL statements
-** using either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
-** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()], then the
-** more specific [error codes] are returned directly
-** by sqlite3_step(). The use of the "v2" interface is recommended.

-**
-** These routines form the "result set query" interface.
-**
-** These routines return information about
-** a single column of the current result row of a query. In every
-** case the first argument is a pointer to the
-** [prepared statement] that is being
-** evaluated (the [sqlite3_stmt*] that was returned from
-** [sqlite3_prepare_v2()] or one of its variants) and
-** the second argument is the index of the column for which information
-** should be returned. The left-most column of the result set
-** has an index of 0.
-**
-** If the SQL statement is not currently point to a valid row, or if the
-** the column index is out of range, the result is undefined.
-** These routines may only be called when the most recent call to
-** [sqlite3_step()] has returned [SQLITE_ROW] and neither
-** [sqlite3_reset()] nor [sqlite3_finalize()] has been call subsequently.
-** If any of these routines are called after [sqlite3_reset()] or
-** [sqlite3_finalize()] or after [sqlite3_step()] has returned
-** something other than [SQLITE_ROW], the results are undefined.
-** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
-** are called from a different thread while any of these routines
-** are pending, then the results are undefined.
-**
-** The sqlite3_column_type() routine returns
-** [SQLITE_INTEGER | datatype code] for the initial data type
-** of the result column. The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL]. The value
-** returned by sqlite3_column_type() is only meaningful if no type
-** conversions have occurred as described below. After a type conversion,
-** the value returned by sqlite3_column_type() is undefined. Future
-** versions of SQLite may change the behavior of sqlite3_column_type()
-** following a type conversion.
-**
-** If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
-** routine returns the number of bytes in that BLOB or string.
-** If the result is a UTF-16 string, then sqlite3_column_bytes() converts
-** the string to UTF-8 and then returns the number of bytes.
-** If the result is a numeric value then sqlite3_column_bytes() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
-** the number of bytes in that string.
-** The value returned does not include the zero terminator at the end
-** of the string. For clarity: the value returned is the number of
-** bytes in the string, not the number of characters.
-**
-** Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
-** even empty strings, are always zero terminated. The return
-** value from sqlite3_column_blob() for a zero-length blob is an arbitrary
-** pointer, possibly even a NULL pointer.
-**
-** The sqlite3_column_bytes16() routine is similar to sqlite3_column_bytes()
-** but leaves the result in UTF-16 in native byte order instead of UTF-8.
-** The zero terminator is not included in this count.
-**
-** These routines attempt to convert the value where appropriate. For
-** example, if the internal representation is FLOAT and a text result
-** is requested, [sqlite3_snprintf()] is used internally to do the conversion
-** automatically. The following table details the conversions that
-** are applied:
-**
-** <blockquote>
-** <table border="1">
-** <tr><th> Internal<br>Type <th> Requested<br>Type <th> Conversion
-**
-** <tr><td> NULL <td> INTEGER <td> Result is 0
-** <tr><td> NULL <td> FLOAT <td> Result is 0.0
-** <tr><td> NULL <td> TEXT <td> Result is NULL pointer
-** <tr><td> NULL <td> BLOB <td> Result is NULL pointer
-** <tr><td> INTEGER <td> FLOAT <td> Convert from integer to float
-** <tr><td> INTEGER <td> TEXT <td> ASCII rendering of the integer
-** <tr><td> INTEGER <td> BLOB <td> Same as for INTEGER->TEXT
-** <tr><td> FLOAT <td> INTEGER <td> Convert from float to integer
-** <tr><td> FLOAT <td> TEXT <td> ASCII rendering of the float
-** <tr><td> FLOAT <td> BLOB <td> Same as FLOAT->TEXT
-** <tr><td> TEXT <td> INTEGER <td> Use atoi()
-** <tr><td> TEXT <td> FLOAT <td> Use atof()
-** <tr><td> TEXT <td> BLOB <td> No change
-** <tr><td> BLOB <td> INTEGER <td> Convert to TEXT then use atoi()
-** <tr><td> BLOB <td> FLOAT <td> Convert to TEXT then use atof()
-** <tr><td> BLOB <td> TEXT <td> Add a zero terminator if needed
-** </table>
-** </blockquote>
-**
-** The table above makes reference to standard C library functions atoi()
-** and atof(). SQLite does not really use these functions. It has its
-** on equavalent internal routines. The atoi() and atof() names are
-** used in the table for brevity and because they are familiar to most
-** C programmers.
-**
-** Note that when type conversions occur, pointers returned by prior
-** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
-** sqlite3_column_text16() may be invalidated.
-** Type conversions and pointer invalidations might occur
-** in the following cases:
-**
-** <ul>
-** <li><p> The initial content is a BLOB and sqlite3_column_text()
-** or sqlite3_column_text16() is called. A zero-terminator might
-** need to be added to the string.</p></li>
-**
-** <li><p> The initial content is UTF-8 text and sqlite3_column_bytes16() or
-** sqlite3_column_text16() is called. The content must be converted
-** to UTF-16.</p></li>
-**
-** <li><p> The initial content is UTF-16 text and sqlite3_column_bytes() or
-** sqlite3_column_text() is called. The content must be converted
-** to UTF-8.</p></li>
-** </ul>
-**
-** Conversions between UTF-16be and UTF-16le are always done in place and do
-** not invalidate a prior pointer, though of course the content of the buffer
-** that the prior pointer points to will have been modified. Other kinds
-** of conversion are done in place when it is possible, but sometime it is
-** not possible and in those cases prior pointers are invalidated.
-**
-** The safest and easiest to remember policy is to invoke these routines
-** in one of the following ways:
-**
-** <ul>
-** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
-** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
-** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
-** </ul>
-**
-** In other words, you should call sqlite3_column_text(), sqlite3_column_blob(),
-** or sqlite3_column_text16() first to force the result into the desired
-** format, then invoke sqlite3_column_bytes() or sqlite3_column_bytes16() to
-** find the size of the result. Do not mix call to sqlite3_column_text() or
-** sqlite3_column_blob() with calls to sqlite3_column_bytes16(). And do not
-** mix calls to sqlite3_column_text16() with calls to sqlite3_column_bytes().
-**
-** The pointers returned are valid until a type conversion occurs as
-** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
-** [sqlite3_finalize()] is called. The memory space used to hold strings
-** and blobs is freed automatically. Do <b>not</b> pass the pointers returned
-** [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
-** [sqlite3_free()].
-**
-** If a memory allocation error occurs during the evaluation of any
-** of these routines, a default value is returned. The default value
-** is either the integer 0, the floating point number 0.0, or a NULL
-** pointer. Subsequent calls to [sqlite3_errcode()] will return

-** or to redefine the behavior of existing SQL functions or aggregates. The
-** difference only between the two is that the second parameter, the

-** sqlite3_create_function() and UTF-16 for sqlite3_create_function16().
-**
-** The first argument is the [database connection] that holds the
-** SQL function or aggregate is to be added or redefined. If a single
-** program uses more than one database handle internally, then SQL
-** functions or aggregates must be added individually to each database
-** handle with which they will be used.
-**
-** The second parameter is the name of the SQL function to be created
-** or redefined.
-** The length of the name is limited to 255 bytes, exclusive of the
-** zero-terminator. Note that the name length limit is in bytes, not
-** characters. Any attempt to create a function with a longer name
-** will result in an SQLITE_ERROR error.
-**
-** The third parameter is the number of arguments that the SQL function or
-** aggregate takes. If this parameter is negative, then the SQL function or
-** aggregate may take any number of arguments.
-**
-** The fourth parameter, eTextRep, specifies what
-** [SQLITE_UTF8 | text encoding] this SQL function prefers for
-** its parameters. Any SQL function implementation should be able to work
-** work with UTF-8, UTF-16le, or UTF-16be. But some implementations may be
-** more efficient with one encoding than another. It is allowed to
-** invoke sqlite3_create_function() or sqlite3_create_function16() multiple
-** times with the same function but with different values of eTextRep.
-** When multiple implementations of the same function are available, SQLite
-** will pick the one that involves the least amount of data conversion.
-** If there is only a single implementation which does not care what
-** text encoding is used, then the fourth argument should be
-** [SQLITE_ANY].
-**
-** The fifth parameter is an arbitrary pointer. The implementation
-** of the function can gain access to this pointer using
-** [sqlite3_user_data()].
-**
-** The seventh, eighth and ninth parameters, xFunc, xStep and xFinal, are
-** pointers to C-language functions that implement the SQL
-** function or aggregate. A scalar SQL function requires an implementation of
-** the xFunc callback only, NULL pointers should be passed as the xStep
-** and xFinal parameters. An aggregate SQL function requires an implementation

-** CAPI3REF: Obtaining SQL Function Parameter Values {F15100}
-**
-** The C-language implementation of SQL functions and aggregates uses
-** this set of interface routines to access the parameter values on
-** the function or aggregate.
-**
-** The xFunc (for scalar functions) or xStep (for aggregates) parameters
-** to [sqlite3_create_function()] and [sqlite3_create_function16()]
-** define callbacks that implement the SQL functions and aggregates.
-** The 4th parameter to these callbacks is an array of pointers to
-** [sqlite3_value] objects. There is one [sqlite3_value] object for
-** each parameter to the SQL function. These routines are used to
-** extract values from the [sqlite3_value] objects.
-**
-** These routines work just like the corresponding
-** [sqlite3_column_blob | sqlite3_column_* routines] except that
-** these routines take a single [sqlite3_value*] pointer instead
-** of an [sqlite3_stmt*] pointer and an integer column number.
-**
-** The sqlite3_value_text16() interface extracts a UTF16 string
-** in the native byte-order of the host machine. The
-** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
-** extract UTF16 strings as big-endian and little-endian respectively.
-**
-** The sqlite3_value_numeric_type() interface attempts to apply
-** numeric affinity to the value. This means that an attempt is
-** made to convert the value to an integer or floating point. If
-** such a conversion is possible without loss of information (in other
-** words if the value is a string that looks like a number)
-** then the conversion is done. Otherwise no conversion occurs. The
-** [SQLITE_INTEGER | datatype] after conversion is returned.
-**
-** Please pay particular attention to the fact that the pointer that
-** is returned from [sqlite3_value_blob()], [sqlite3_value_text()], or
-** [sqlite3_value_text16()] can be invalidated by a subsequent call to
-** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
-** or [sqlite3_value_text16()].
-**
-** These routines must be called from the same thread as
-** the SQL function that supplied the sqlite3_value* parameters.
-** Or, if the sqlite3_value* argument comes from the [sqlite3_column_value()]
-** interface, then these routines should be called from the same thread
-** that ran [sqlite3_column_value()].

-** {F16403} The sqlite3_result_zeroblob() inerfaces set the result of

-** bytes and N bytes in size, where N is the value of the 2nd parameter.
-**
-** {F16407} The sqlite3_result_double() interface sets the result from

-** by its 2nd argument.
-**
-** {F16409} The sqlite3_result_error() and sqlite3_result_error16() functions
-** cause the implemented SQL function to throw an exception.
-** {F16411} SQLite uses the string pointed to by the
-** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
-** as the text of an error message. {F16412} SQLite interprets the error
-** message string from sqlite3_result_error() as UTF8. {F16413} SQLite

-** the error code is SQLITE_ERROR.
-**
-** {F16421} The sqlite3_result_toobig() interface causes SQLite

-** to represent. {F16422} The sqlite3_result_nomem() interface
-** causes SQLite to throw an exception indicating that the a

-** {F16447} If the 3rd parameter to the sqlite3_result_text* interfaces
-** is non-negative, then as many bytes (not characters) of the text

-** function result.
-** {F16451} If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
-** function as the destructor on the text or blob result when it has
-** finished using that result.
-** {F16453} If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_STATIC, then

-** CAPI3REF: Mutexes {F17000}
-**
-** The SQLite core uses these routines for thread
-** synchronization. Though they are intended for internal
-** use by SQLite, code that links against SQLite is
-** permitted to use any of these routines.
-**
-** The SQLite source code contains multiple implementations
-** of these mutex routines. An appropriate implementation
-** is selected automatically at compile-time. The following
-** implementations are available in the SQLite core:
-**
-** <ul>
-** <li> SQLITE_MUTEX_OS2
-** <li> SQLITE_MUTEX_PTHREAD
-** <li> SQLITE_MUTEX_W32
-** <li> SQLITE_MUTEX_NOOP
-** </ul>
-**
-** The SQLITE_MUTEX_NOOP implementation is a set of routines
-** that does no real locking and is appropriate for use in
-** a single-threaded application. The SQLITE_MUTEX_OS2,
-** SQLITE_MUTEX_PTHREAD, and SQLITE_MUTEX_W32 implementations
-** are appropriate for use on os/2, unix, and windows.
-**
-** If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor
-** macro defined (with "-DSQLITE_MUTEX_APPDEF=1"), then no mutex
-** implementation is included with the library. The
-** mutex interface routines defined here become external
-** references in the SQLite library for which implementations
-** must be provided by the application. This facility allows an
-** application that links against SQLite to provide its own mutex
-** implementation without having to modify the SQLite core.
-**
-** {F17011} The sqlite3_mutex_alloc() routine allocates a new
-** mutex and returns a pointer to it. {F17012} If it returns NULL
-** that means that a mutex could not be allocated. {F17013} SQLite
-** will unwind its stack and return an error. {F17014} The argument
-** to sqlite3_mutex_alloc() is one of these integer constants:
-**
-** <ul>
-** <li> SQLITE_MUTEX_FAST
-** <li> SQLITE_MUTEX_RECURSIVE
-** <li> SQLITE_MUTEX_STATIC_MASTER
-** <li> SQLITE_MUTEX_STATIC_MEM
-** <li> SQLITE_MUTEX_STATIC_MEM2
-** <li> SQLITE_MUTEX_STATIC_PRNG
-** <li> SQLITE_MUTEX_STATIC_LRU
-** </ul> {END}
-**
-** {F17015} The first two constants cause sqlite3_mutex_alloc() to create
-** a new mutex. The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
-** is used but not necessarily so when SQLITE_MUTEX_FAST is used. {END}
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to. {F17016} But SQLite will only request a recursive mutex in
-** cases where it really needs one. {END} If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** {F17017} The other allowed parameters to sqlite3_mutex_alloc() each return
-** a pointer to a static preexisting mutex. {END} Four static mutexes are
-** used by the current version of SQLite. Future versions of SQLite
-** may add additional static mutexes. Static mutexes are for internal
-** use by SQLite only. Applications that use SQLite mutexes should
-** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
-** SQLITE_MUTEX_RECURSIVE.
-**
-** {F17018} Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
-** returns a different mutex on every call. {F17034} But for the static
-** mutex types, the same mutex is returned on every call that has
-** the same type number. {END}
-**
-** {F17019} The sqlite3_mutex_free() routine deallocates a previously
-** allocated dynamic mutex. {F17020} SQLite is careful to deallocate every
-** dynamic mutex that it allocates. {U17021} The dynamic mutexes must not be in
-** use when they are deallocated. {U17022} Attempting to deallocate a static
-** mutex results in undefined behavior. {F17023} SQLite never deallocates
-** a static mutex. {END}
-**
-** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
-** to enter a mutex. {F17024} If another thread is already within the mutex,
-** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
-** SQLITE_BUSY. {F17025} The sqlite3_mutex_try() interface returns SQLITE_OK
-** upon successful entry. {F17026} Mutexes created using
-** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
-** {F17027} In such cases the,
-** mutex must be exited an equal number of times before another thread
-** can enter. {U17028} If the same thread tries to enter any other
-** kind of mutex more than once, the behavior is undefined.
-** {F17029} SQLite will never exhibit
-** such behavior in its own use of mutexes. {END}
-**
-** Some systems (ex: windows95) do not the operation implemented by
-** sqlite3_mutex_try(). On those systems, sqlite3_mutex_try() will
-** always return SQLITE_BUSY. {F17030} The SQLite core only ever uses
-** sqlite3_mutex_try() as an optimization so this is acceptable behavior. {END}
-**
-** {F17031} The sqlite3_mutex_leave() routine exits a mutex that was
-** previously entered by the same thread. {U17032} The behavior
-** is undefined if the mutex is not currently entered by the
-** calling thread or is not currently allocated. {F17033} SQLite will
-** never do either. {END}

-** handles housekeeping details such as creating and deleting
-** VDBE instances. This file is solely interested in executing
-** the VDBE program.
-**
-** In the external interface, an "sqlite3_stmt*" is an opaque pointer
-** to a VDBE.
-**
-** The SQL parser generates a program which is then executed by
-** the VDBE to do the work of the SQL statement. VDBE programs are
-** similar in form to assembly language. The program consists of
-** a linear sequence of operations. Each operation has an opcode
-** and 5 operands. Operands P1, P2, and P3 are integers. Operand P4
-** is a null-terminated string. Operand P5 is an unsigned character.
-** Few opcodes use all 5 operands.
-**
-** Computation results are stored on a set of registers numbered beginning
-** with 1 and going up to Vdbe.nMem. Each register can store
-** either an integer, a null-terminated string, a floating point
-** number, or the SQL "NULL" value. An inplicit conversion from one
-** type to the other occurs as necessary.
-**
-** Most of the code in this file is taken up by the sqlite3VdbeExec()

-** will be filled with #defines that give unique integer values to each

-** each string is the symbolic name for the corresponding opcode. If the
-** case statement is followed by a comment of the form "/# same as ... #/"
-** that comment is used to determine the particular value of the opcode.
-**
-** Other keywords in the comment that follows each case are used to
-** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
-** Keywords include: in1, in2, in3, out2_prerelease, out2, out3. See

-** encapsulate the code that serializes values for storage in SQLite
-** data and index records. Each serialized value consists of a
-** 'serial-type' and a blob of data. The serial type is an 8-byte unsigned
-** integer, stored as a varint.
-**
-** In an SQLite index record, the serial type is stored directly before
-** the blob of data that it corresponds to. In a table record, all serial
-** types are stored at the start of the record, and the blobs of data at
-** the end. Hence these functions allow the caller to handle the
-** serial-type and data blob seperately.
-**
-** The following table describes the various storage classes for data:
-**
-** serial type bytes of data type
-** -------------- --------------- ---------------
-** 0 0 NULL
-** 1 1 signed integer
-** 2 2 signed integer
-** 3 3 signed integer
-** 4 4 signed integer
-** 5 6 signed integer
-** 6 8 signed integer
-** 7 8 IEEE float
-** 8 0 Integer constant 0
-** 9 0 Integer constant 1
-** 10,11 reserved for expansion
-** N>=12 and even (N-12)/2 BLOB
-** N>=13 and odd (N-13)/2 text
-**
-** The 8 and 9 types were added in 3.3.0, file format 4. Prior versions
-** of SQLite will not understand those serial types.

-**
-** (later): It is reported to me that the mixed-endian problem
-** on ARM7 is an issue with GCC, not with the ARM7 chip. It seems
-** that early versions of GCC stored the two words of a 64-bit
-** float in the wrong order. And that error has been propagated
-** ever since. The blame is not necessarily with GCC, though.
-** GCC might have just copying the problem from a prior compiler.
-** I am also told that newer versions of GCC that follow a different
-** ABI get the byte order right.
-**
-** Developers using SQLite on an ARM7 should compile and run their
-** application using -DSQLITE_DEBUG=1 at least once. With DEBUG
-** enabled, some asserts below will ensure that the byte order of
-** floating point values is correct.
-**
-** (2007-08-30) Frank van Vugt has studied this problem closely
-** and has send his findings to the SQLite developers. Frank
-** writes that some Linux kernels offer floating point hardware
-** emulation that uses only 32-bit mantissas instead of a full
-** 48-bits as required by the IEEE standard. (This is the
-** CONFIG_FPE_FASTFPE option.) On such systems, floating point
-** byte swapping becomes very complicated. To avoid problems,
-** the necessary byte swapping is carried out using a 64-bit integer
-** rather than a 64-bit float. Frank assures us that the code here
-** works for him. We, the developers, have no way to independently
-** verify this, but Frank seems to know what he is talking about
-** so we trust him.

-** The query generator uses an array of instances of this structure to

-**
-** All WhereTerms are collected into a single WhereClause structure.
-** The following identity holds:
-**
-** WhereTerm.pWC->a[WhereTerm.idx] == WhereTerm
-**
-** When a term is of the form:
-**
-** X <op> <expr>
-**
-** where X is a column name and <op> is one of certain operators,
-** then WhereTerm.leftCursor and WhereTerm.leftColumn record the

-**
-** prereqRight and prereqAll record sets of cursor numbers,
-** but they do so indirectly. A single ExprMaskSet structure translates
-** cursor number into bits and the translated bit is stored in the prereq
-** fields. The translation is used in order to maximize the number of
-** bits that will fit in a Bitmask. The VDBE cursor numbers might be
-** spread out over the non-negative integers. For example, the cursor
-** numbers might be 3, 8, 9, 10, 20, 23, 41, and 45. The ExprMaskSet
-** translates these sparse cursor numbers into consecutive integers
-** beginning with 0 in order to make the best possible use of the available
-** bits in the Bitmask. So, in the example above, the cursor numbers

-** SELECT * FROM t1, t2, t3 WHERE ...;
-**
-** Then the code generated is conceptually like the following:
-**
-** foreach row1 in t1 do \ Code generated
-** foreach row2 in t2 do |-- by sqlite3WhereBegin()
-** foreach row3 in t3 do /
-** ...
-** end \ Code generated
-** end |-- by sqlite3WhereEnd()
-** end /
-**
-** Note that the loops might not be nested in the order in which they
-** appear in the FROM clause if a different order is better able to make
-** use of indices. Note also that when the IN operator appears in
-** the WHERE clause, it might result in additional nested loops for
-** scanning through all values on the right-hand side of the IN.
-**
-** There are Btree cursors associated with each table. t1 uses cursor
-** number pTabList->a[0].iCursor. t2 uses the cursor pTabList->a[1].iCursor.
-** And so forth. This routine generates code to open those VDBE cursors
-** and sqlite3WhereEnd() generates the code to close them.
-**
-** The code that sqlite3WhereBegin() generates leaves the cursors named
-** in pTabList pointing at their appropriate entries. The [...] code
-** can use OP_Column and OP_Rowid opcodes on these cursors to extract
-** data from the various tables of the loop.
-**
-** If the WHERE clause is empty, the foreach loops must each scan their
-** entire tables. Thus a three-way join is an O(N^3) operation. But if
-** the tables have indices and there are terms in the WHERE clause that
-** refer to those indices, a complete table scan can be avoided and the
-** code will run much faster. Most of the work of this routine is checking
-** to see if there are indices that can be used to speed up the loop.
-**
-** Terms of the WHERE clause are also used to limit which rows actually
-** make it to the "..." in the middle of the loop. After each "foreach",
-** terms of the WHERE clause that use only terms in that loop and outer
-** loops are evaluated and if false a jump is made around all subsequent
-** inner loops (or around the "..." if the test occurs within the inner-
-** most loop)
-**
-** OUTER JOINS
-**
-** An outer join of tables t1 and t2 is conceptally coded as follows:
-**
-** foreach row1 in t1 do
-** flag = 0
-** foreach row2 in t2 do
-** start:
-** ...
-** flag = 1
-** end
-** if flag==0 then
-** move the row2 cursor to a null row
-** goto start
-** fi
-** end
-**
-** ORDER BY CLAUSE PROCESSING
-**
-** *ppOrderBy is a pointer to the ORDER BY clause of a SELECT statement,
-** if there is one. If there is no ORDER BY clause or if this routine
-** is called from an UPDATE or DELETE statement, then ppOrderBy is NULL.
-**
-** If an index can be used so that the natural output order of the table
-** scan is correct for the ORDER BY clause, then that index is used and
-** *ppOrderBy is set to NULL. This is an optimization that prevents an
-** unnecessary sort of the result set if an index appropriate for the
-** ORDER BY clause already exists.
-**
-** If the where clause loops cannot be arranged to provide the correct
-** output order, then the *ppOrderBy is unchanged.

-** Suppose the action integer is N. Then the action is determined as

-**
-** 0 <= N < YYNSTATE Shift N. That is, push the lookahead

-This script is a tool to help track down memory leaks in the sqlite
-library. The library must be compiled with the preprocessor symbol
-SQLITE_MEMDEBUG set to at least 2. It must be set to 3 to enable stack
-traces.
-
-To use, run the leaky application and save the standard error output.
-Then, execute this program with the first argument the name of the
-application binary (or interpreter) and the second argument the name of the
-text file that contains the collected stderr output.
-
-If all goes well a summary of unfreed allocations is printed out. If the
-GNU C library is in use and SQLITE_DEBUG is 3 or greater a stack trace is
-printed out for each unmatched allocation.
-
-If the \"-r <n>\" option is passed, then the program stops and prints out
-the state of the heap immediately after the <n>th call to malloc() or
-realloc().
-

-
-$ ./testfixture ../sqlite/test/select1.test 2> memtrace.out

-This Tcl script is used to test the various compile time options
-available for omitting code (the SQLITE_OMIT_xxx options). It
-should be invoked as follows:
-
- <script> ?-makefile PATH-TO-MAKEFILE?
-
-The default value for ::MAKEFILE is "../Makefile.linux.gcc".
-
-This script builds the testfixture program and runs the SQLite test suite
-once with each SQLITE_OMIT_ option defined and then once with all options
-defined together. Each run is performed in a seperate directory created
-as a sub-directory of the current directory by the script. The output
-of the build is saved in <sub-directory>/build.log. The output of the
-test-suite is saved in <sub-directory>/test.log.
-
-Almost any SQLite makefile (except those generated by configure - see below)
-should work. The following properties are required:
-
- * The makefile should support the "testfixture" target.
- * The makefile should support the "test" target.
- * The makefile should support the variable "OPTS" as a way to pass
- options from the make command line to lemon and the C compiler.
-
-More precisely, the following two invocations must be supported:
-
- make -f $::MAKEFILE testfixture OPTS="-DSQLITE_OMIT_ALTERTABLE=1"
- make -f $::MAKEFILE test
-
-Makefiles generated by the sqlite configure program cannot be used as
-they do not respect the OPTS variable.

-database entries have a combined key and data size of less than
-144 bytes. So if a leaf node in the new database is able to
-store 144 bytes of combined key and data, only 1% of the leaves
-will require overflow pages. Furthermore, note that no key
-is larger than 99 bytes, so if the key will never be on an
-overflow page.
-
-The average combined size of key+data is 48. Add in 16 bytes of
-overhead for a total of 64. That means that a 1K page will

-
- 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.
-
-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.
-
-Fragmentation
-
- The percentage of pages in the table or index that are not
- consecutive in the disk file. Many filesystems are optimized
- for sequential file access so smaller fragmentation numbers
- sometimes result in faster queries, especially for larger
- database files that do not fit in the disk cache.
-
-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.

-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.
