# Begin SQLite README.md
<h1 align="center">SQLite Source Repository</h1>
This repository contains the complete source code for the
[SQLite database engine](https://sqlite.org/). Some test scripts
are also included. However, many other test scripts
and most of the documentation are managed separately.
SQLite [does not use Git](https://sqlite.org/whynotgit.html).
If you are reading this on GitHub, then you are looking at an
unofficial mirror. See <https://sqlite.org/src> for the official
repository.
## Obtaining The Code
SQLite sources are managed using the
[Fossil](https://www.fossil-scm.org/), a distributed version control system
that was specifically designed to support SQLite development.
If you do not want to use Fossil, you can download tarballs or ZIP
archives or [SQLite archives](https://sqlite.org/cli.html#sqlar) as follows:
* Lastest trunk check-in as
[Tarball](https://www.sqlite.org/src/tarball/sqlite.tar.gz),
[ZIP-archive](https://www.sqlite.org/src/zip/sqlite.zip), or
[SQLite-archive](https://www.sqlite.org/src/sqlar/sqlite.sqlar).
* Latest release as
[Tarball](https://www.sqlite.org/src/tarball/sqlite.tar.gz?r=release),
[ZIP-archive](https://www.sqlite.org/src/zip/sqlite.zip?r=release), or
[SQLite-archive](https://www.sqlite.org/src/sqlar/sqlite.sqlar?r=release).
* For other check-ins, substitute an appropriate branch name or
tag or hash prefix for "release" in the URLs of the previous
bullet. Or browse the [timeline](https://www.sqlite.org/src/timeline)
to locate the check-in desired, click on its information page link,
then click on the "Tarball" or "ZIP Archive" links on the information
page.
If you do want to use Fossil to check out the source tree,
first install Fossil version 2.0 or later.
(Source tarballs and precompiled binaries available
[here](https://www.fossil-scm.org/fossil/uv/download.html). Fossil is
a stand-alone program. To install, simply download or build the single
executable file and put that file someplace on your $PATH.)
Then run commands like this:
mkdir ~/sqlite
cd ~/sqlite
fossil clone https://www.sqlite.org/src sqlite.fossil
fossil open sqlite.fossil
After setting up a repository using the steps above, you can always
update to the lastest version using:
fossil update trunk ;# latest trunk check-in
fossil update release ;# latest official release
Or type "fossil ui" to get a web-based user interface.
## Compiling
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 sqlite3.c ;# Build the "amalgamation" source file
make test ;# Run some tests (requires Tcl)
See the makefile for additional targets.
The configure script uses autoconf 2.61 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 suit your needs. Comments on the generic makefile
show what changes are needed.
## Using MSVC
On Windows, all applicable build products can be compiled with MSVC.
First open the command prompt window associated with the desired compiler
version (e.g. "Developer Command Prompt for VS2013"). Next, use NMAKE
with the provided "Makefile.msc" to build one of the supported targets.
For example:
mkdir bld
cd bld
nmake /f Makefile.msc TOP=..\sqlite
nmake /f Makefile.msc sqlite3.c TOP=..\sqlite
nmake /f Makefile.msc sqlite3.dll TOP=..\sqlite
nmake /f Makefile.msc sqlite3.exe TOP=..\sqlite
nmake /f Makefile.msc test TOP=..\sqlite
There are several build options that can be set via the NMAKE command
line. For example, to build for WinRT, simply add "FOR_WINRT=1" argument
to the "sqlite3.dll" command line above. When debugging into the SQLite
code, adding the "DEBUG=1" argument to one of the above command lines is
recommended.
SQLite does not require [Tcl](http://www.tcl.tk/) to run, but a Tcl installation
is required by the makefiles (including those for MSVC). SQLite contains
a lot of generated code and Tcl is used to do much of that code generation.
## Source Code Tour
Most of the core source files are in the **src/** subdirectory. The
**src/** folder also contains files used to build the "testfixture" test
harness. The names of the source files used by "testfixture" all begin
with "test".
The **src/** also contains the "shell.c" file
which is the main program for the "sqlite3.exe"
[command-line shell](https://sqlite.org/cli.html) and
the "tclsqlite.c" file which implements the
[Tcl bindings](https://sqlite.org/tclsqlite.html) for SQLite.
(Historical note: SQLite began as a Tcl
extension and only later escaped to the wild as an independent library.)
Test scripts and programs are found in the **test/** subdirectory.
Addtional test code is found in other source repositories.
See [How SQLite Is Tested](http://www.sqlite.org/testing.html) for
additional information.
The **ext/** subdirectory contains code for extensions. The
Full-text search engine is in **ext/fts3**. The R-Tree engine is in
**ext/rtree**. The **ext/misc** subdirectory contains a number of
smaller, single-file extensions, such as a REGEXP operator.
The **tool/** subdirectory contains various scripts and programs used
for building generated source code files or for testing or for generating
accessory programs such as "sqlite3_analyzer(.exe)".
### Generated Source Code Files
Several of the C-language source files used by SQLite are generated from
other sources rather than being typed in manually by a programmer. This
section will summarize those automatically-generated files. To create all
of the automatically-generated files, simply run "make target&#95;source".
The "target&#95;source" make target will create a subdirectory "tsrc/" and
fill it with all the source files needed to build SQLite, both
manually-edited files and automatically-generated files.
The SQLite interface is defined by the **sqlite3.h** header file, which is
generated from src/sqlite.h.in, ./manifest.uuid, and ./VERSION. The
[Tcl script](http://www.tcl.tk) at tool/mksqlite3h.tcl does the conversion.
The manifest.uuid file contains the SHA3 hash of the particular check-in
and is used to generate the SQLITE\_SOURCE\_ID macro. The VERSION file
contains the current SQLite version number. The sqlite3.h header is really
just a copy of src/sqlite.h.in with the source-id and version number inserted
at just the right spots. Note that comment text in the sqlite3.h file is
used to generate much of the SQLite API documentation. The Tcl scripts
used to generate that documentation are in a separate source repository.
The SQL language parser is **parse.c** which is generate from a grammar in
the src/parse.y file. The conversion of "parse.y" into "parse.c" is done
by the [lemon](./doc/lemon.html) LALR(1) parser generator. The source code
for lemon is at tool/lemon.c. Lemon uses the tool/lempar.c file as a
template for generating its parser.
Lemon also generates the **parse.h** header file, at the same time it
generates parse.c. But the parse.h header file is
modified further (to add additional symbols) using the ./addopcodes.tcl
Tcl script.
The **opcodes.h** header file contains macros that define the numbers
corresponding to opcodes in the "VDBE" virtual machine. The opcodes.h
file is generated by the scanning the src/vdbe.c source file. The
Tcl script at ./mkopcodeh.tcl does this scan and generates opcodes.h.
A second Tcl script, ./mkopcodec.tcl, then scans opcodes.h to generate
the **opcodes.c** source file, which contains a reverse mapping from
opcode-number to opcode-name that is used for EXPLAIN output.
The **keywordhash.h** header file contains the definition of a hash table
that maps SQL language keywords (ex: "CREATE", "SELECT", "INDEX", etc.) into
the numeric codes used by the parse.c parser. The keywordhash.h file is
generated by a C-language program at tool mkkeywordhash.c.
The **pragma.h** header file contains various definitions used to parse
and implement the PRAGMA statements. The header is generated by a
script **tool/mkpragmatab.tcl**. If you want to add a new PRAGMA, edit
the **tool/mkpragmatab.tcl** file to insert the information needed by the
parser for your new PRAGMA, then run the script to regenerate the
**pragma.h** header file.
### The Amalgamation
All of the individual C source code and header files (both manually-edited
and automatically-generated) can be combined into a single big source file
**sqlite3.c** called "the amalgamation". The amalgamation is the recommended
way of using SQLite in a larger application. Combining all individual
source code files into a single big source code file allows the C compiler
to perform more cross-procedure analysis and generate better code. SQLite
runs about 5% faster when compiled from the amalgamation versus when compiled
from individual source files.
The amalgamation is generated from the tool/mksqlite3c.tcl Tcl script.
First, all of the individual source files must be gathered into the tsrc/
subdirectory (using the equivalent of "make target_source") then the
tool/mksqlite3c.tcl script is run to copy them all together in just the
right order while resolving internal "#include" references.
The amalgamation source file is more than 200K lines long. Some symbolic
debuggers (most notably MSVC) are unable to deal with files longer than 64K
lines. To work around this, a separate Tcl script, tool/split-sqlite3c.tcl,
can be run on the amalgamation to break it up into a single small C file
called **sqlite3-all.c** that does #include on about seven other files
named **sqlite3-1.c**, **sqlite3-2.c**, ..., **sqlite3-7.c**. In this way,
all of the source code is contained within a single translation unit so
that the compiler can do extra cross-procedure optimization, but no
individual source file exceeds 32K lines in length.
## How It All Fits Together
SQLite is modular in design.
See the [architectural description](http://www.sqlite.org/arch.html)
for details. Other documents that are useful in
(helping to understand how SQLite works include the
[file format](http://www.sqlite.org/fileformat2.html) description,
the [virtual machine](http://www.sqlite.org/opcode.html) that runs
prepared statements, the description of
[how transactions work](http://www.sqlite.org/atomiccommit.html), and
the [overview of the query planner](http://www.sqlite.org/optoverview.html).
Years of effort have gone into optimizating SQLite, both
for small size and high performance. And optimizations tend to result in
complex code. So there is a lot of complexity in the current SQLite
implementation. It will not be the easiest library in the world to hack.
Key files:
* **sqlite.h.in** - This file defines the public interface to the SQLite
library. Readers will need to be familiar with this interface before
trying to understand how the library works internally.
* **sqliteInt.h** - this header file defines many of the data objects
used internally by SQLite. In addition to "sqliteInt.h", some
subsystems have their own header files.
* **parse.y** - This file describes the LALR(1) grammar that SQLite uses
to parse SQL statements, and the actions that are taken at each step
in the parsing process.
* **vdbe.c** - This file implements the virtual machine that runs
prepared statements. There are various helper files whose names
begin with "vdbe". The VDBE has access to the vdbeInt.h header file
which defines internal data objects. The rest of SQLite interacts
with the VDBE through an interface defined by vdbe.h.
* **where.c** - This file (together with its helper files named
by "where*.c") analyzes the WHERE clause and generates
virtual machine code to run queries efficiently. This file is
sometimes called the "query optimizer". It has its own private
header file, whereInt.h, that defines data objects used internally.
* **btree.c** - This file contains the implementation of the B-Tree
storage engine used by SQLite. The interface to the rest of the system
is defined by "btree.h". The "btreeInt.h" header defines objects
used internally by btree.c and not published to the rest of the system.
* **pager.c** - This file contains the "pager" implementation, the
module that implements transactions. The "pager.h" header file
defines the interface between pager.c and the rest of the system.
* **os_unix.c** and **os_win.c** - These two files implement the interface
between SQLite and the underlying operating system using the run-time
pluggable VFS interface.
* **shell.c.in** - This file is not part of the core SQLite library. This
is the file that, when linked against sqlite3.a, generates the
"sqlite3.exe" command-line shell. The "shell.c.in" file is transformed
into "shell.c" as part of the build process.
* **tclsqlite.c** - This file implements the Tcl bindings for SQLite. It
is not part of the core SQLite library. But as most of the tests in this
repository are written in Tcl, the Tcl language bindings are important.
* **test*.c** - Files in the src/ folder that begin with "test" go into
building the "testfixture.exe" program. The testfixture.exe program is
an enhanced Tcl shell. The testfixture.exe program runs scripts in the
test/ folder to validate the core SQLite code. The testfixture program
(and some other test programs too) is build and run when you type
"make test".
* **ext/misc/json1.c** - This file implements the various JSON functions
that are build into SQLite.
There are many other source files. Each has a succinct header comment that
describes its purpose and role within the larger system.

SQLite's OS layer contains the following definitions used in F2FS related
calls:
#define F2FS_IOCTL_MAGIC 0xf5
#define F2FS_IOC_START_ATOMIC_WRITE _IO(F2FS_IOCTL_MAGIC, 1)
#define F2FS_IOC_COMMIT_ATOMIC_WRITE _IO(F2FS_IOCTL_MAGIC, 2)
#define F2FS_IOC_START_VOLATILE_WRITE _IO(F2FS_IOCTL_MAGIC, 3)
#define F2FS_IOC_ABORT_VOLATILE_WRITE _IO(F2FS_IOCTL_MAGIC, 5)
#define F2FS_IOC_GET_FEATURES _IOR(F2FS_IOCTL_MAGIC, 12, u32)
#define F2FS_FEATURE_ATOMIC_WRITE 0x0004
After opening a database file on Linux (including Android), SQLite determines
whether or not a file supports F2FS atomic commits as follows:
u32 flags = 0;
rc = ioctl(fd, F2FS_IOC_GET_FEATURES, &flags);
if( rc==0 && (flags & F2FS_FEATURE_ATOMIC_WRITE) ){
/* File supports F2FS atomic commits */
}else{
/* File does NOT support F2FS atomic commits */
}
where "fd" is the file-descriptor open on the database file.
Usually, when writing to a database file that supports atomic commits, SQLite
accumulates the entire transaction in heap memory, deferring all writes to the
db file until the transaction is committed.
When it is time to commit a transaction on a file that supports atomic
commits, SQLite does:
/* Take an F_WRLCK lock on the database file. This prevents any other
** SQLite clients from reading or writing the file until the lock
** is released. */
rc = fcntl(fd, F_SETLK, ...);
if( rc!=0 ) goto failed;
rc = ioctl(fd, F2FS_IOC_START_ATOMIC_WRITE);
if( rc!=0 ) goto fallback_to_legacy_journal_commit;
foreach (dirty page){
rc = write(fd, ...dirty page...);
if( rc!=0 ){
ioctl(fd, F2FS_IOC_ABORT_VOLATILE_WRITE);
goto fallback_to_legacy_journal_commit;
}
}
rc = ioctl(fd, F2FS_IOC_COMMIT_ATOMIC_WRITE);
if( rc!=0 ){
ioctl(fd, F2FS_IOC_ABORT_VOLATILE_WRITE);
goto fallback_to_legacy_journal_commit;
}
/* If we get there, the transaction has been successfully
** committed to persistent storage. The following call
** relinquishes the F_WRLCK lock. */
fcntl(fd, F_SETLK, ...);
Assumptions:
1. After either of the F2FS_IOC_ABORT_VOLATILE_WRITE calls return,
the database file is in the state that it was in before
F2FS_IOC_START_ATOMIC_WRITE was invoked. Even if the ioctl()
fails - we're ignoring the return code.
This is true regardless of the type of error that occurred in
ioctl() or write().
2. If the system fails before the F2FS_IOC_COMMIT_ATOMIC_WRITE is
completed, then following a reboot the database file is in the
state that it was in before F2FS_IOC_START_ATOMIC_WRITE was invoked.
Or, if the write was commited right before the system failed, in a
state indicating that all write() calls were successfully committed
to persistent storage before the failure occurred.
3. If the process crashes before the F2FS_IOC_COMMIT_ATOMIC_WRITE is
completed then the file is automatically restored to the state that
it was in before F2FS_IOC_START_ATOMIC_WRITE was called. This occurs
before the posix advisory lock is automatically dropped - there is
no chance that another client will be able to read the file in a
half-committed state before the rollback operation occurs.

## SQLite Expert Extension
This folder contains code for a simple system to propose useful indexes
given a database and a set of SQL queries. It works as follows:
1. The user database schema is copied to a temporary database.
1. All SQL queries are prepared against the temporary database.
Information regarding the WHERE and ORDER BY clauses, and other query
features that affect index selection are recorded.
1. The information gathered in step 2 is used to create candidate
indexes - indexes that the planner might have made use of in the previous
step, had they been available.
1. A subset of the data in the user database is used to generate statistics
for all existing indexes and the candidate indexes generated in step 3
above.
1. The SQL queries are prepared a second time. If the planner uses any
of the indexes created in step 3, they are recommended to the user.
# C API
The SQLite expert C API is defined in sqlite3expert.h. Most uses will proceed
as follows:
1. An sqlite3expert object is created by calling **sqlite3\_expert\_new()**.
A database handle opened by the user is passed as an argument.
1. The sqlite3expert object is configured with one or more SQL statements
by making one or more calls to **sqlite3\_expert\_sql()**. Each call may
specify a single SQL statement, or multiple statements separated by
semi-colons.
1. Optionally, the **sqlite3\_expert\_config()** API may be used to
configure the size of the data subset used to generate index statistics.
Using a smaller subset of the data can speed up the analysis.
1. **sqlite3\_expert\_analyze()** is called to run the analysis.
1. One or more calls are made to **sqlite3\_expert\_report()** to extract
components of the results of the analysis.
1. **sqlite3\_expert\_destroy()** is called to free all resources.
Refer to comments in sqlite3expert.h for further details.
# sqlite3_expert application
The file "expert.c" contains the code for a command line application that
uses the API described above. It can be compiled with (for example):
<pre>
gcc -O2 sqlite3.c expert.c sqlite3expert.c -o sqlite3_expert
</pre>
Assuming the database is named "test.db", it can then be run to analyze a
single query:
<pre>
./sqlite3_expert -sql &lt;sql-query&gt; test.db
</pre>
Or an entire text file worth of queries with:
<pre>
./sqlite3_expert -file &lt;text-file&gt; test.db
</pre>
By default, sqlite3\_expert generates index statistics using all the data in
the user database. For a large database, this may be prohibitively time
consuming. The "-sample" option may be used to configure sqlite3\_expert to
generate statistics based on an integer percentage of the user database as
follows:
<pre>
# Generate statistics based on 25% of the user database rows:
./sqlite3_expert -sample 25 -sql &lt;sql-query&gt; test.db
# Do not generate any statistics at all:
./sqlite3_expert -sample 0 -sql &lt;sql-query&gt; test.db
</pre>

** Configure an sqlite3expert object.
**
** EXPERT_CONFIG_SAMPLE:
** By default, sqlite3_expert_analyze() generates sqlite_stat1 data for
** each candidate index. This involves scanning and sorting the entire
** contents of each user database table once for each candidate index
** associated with the table. For large databases, this can be
** prohibitively slow. This option allows the sqlite3expert object to
** be configured so that sqlite_stat1 data is instead generated based on a
** subset of each table, or so that no sqlite_stat1 data is used at all.
**
** A single integer argument is passed to this option. If the value is less
** than or equal to zero, then no sqlite_stat1 data is generated or used by
** the analysis - indexes are recommended based on the database schema only.
** Or, if the value is 100 or greater, complete sqlite_stat1 data is
** generated for each candidate index (this is the default). Finally, if the
** value falls between 0 and 100, then it represents the percentage of user
** table rows that should be considered when generating sqlite_stat1 data.
**
** Examples:
**
** // Do not generate any sqlite_stat1 data
** sqlite3_expert_config(pExpert, EXPERT_CONFIG_SAMPLE, 0);
**
** // Generate sqlite_stat1 data based on 10% of the rows in each table.

** using sqlite3_free().
**

# The tests in this file test the outcome of a schema-reset happening
# within the xConnect() method of an FTS5 table. At one point this
# was causing a problem in SQLite. Each test proceeds as follows:
#
# 1. Connection [db] opens the db and reads from some unrelated, non-FTS5
# table causing SQLite to load the db schema into memory.
#
# 2. Connection [db2] opens the db and modifies the db schema.
#
# 3. Connection [db] reads or writes an existing fts5 table. That the
# schema has been modified is detected inside the fts5 xConnect()
# callback that is invoked by sqlite3_prepare().
#
# 4. Verify that the statement in 3 has worked. SQLite should detect
# that the schema has changed and successfully prepare the
# statement against the new schema.
#
# Test plan:
#
# 1.*: Trigger the xConnect()/schema-reset using statements executed
# directly against an FTS5 table.
#
# 2.*: Using various statements executed by various BEFORE triggers.
#
# 3.*: Using various statements executed by various AFTER triggers.
#
# 4.*: Using various statements executed by various INSTEAD OF triggers.

*************************************************************************
**
** This file implements a simple virtual table wrapper around the LSM
** This file implements a virtual table for SQLite3 around the LSM
** storage engine from SQLite4.
**
** USAGE
**
** CREATE VIRTUAL TABLE demo USING lsm1(filename,key,keytype,value1,...);
**
** The filename parameter is the name of the LSM database file, which is
** separate and distinct from the SQLite3 database file.
**
** The keytype must be one of: UINT, TEXT, BLOB. All keys must be of that
** one type. "UINT" means unsigned integer. The values may be of any
** SQLite datatype: BLOB, TEXT, INTEGER, FLOAT, or NULL.
**
** The virtual table contains read-only hidden columns:
**
** lsm1_key A BLOB which is the raw LSM key. If the "keytype"
** is BLOB or TEXT then this column is exactly the
** same as the key. For the UINT keytype, this column
** will be a variable-length integer encoding of the key.
**
** lsm1_value A BLOB which is the raw LSM value. All of the value
** columns are packed into this BLOB using the encoding
** described below.
**
** Attempts to write values into the lsm1_key and lsm1_value columns are
** silently ignored.
**
** EXAMPLE
**
** The virtual table declared this way:
**
** CREATE VIRTUAL TABLE demo2 USING lsm1('x.lsm',id,UINT,a,b,c,d);
**
** Results in a new virtual table named "demo2" that acts as if it has
** the following schema:
**
** CREATE TABLE demo2(
** id UINT PRIMARY KEY ON CONFLICT REPLACE,
** a ANY,
** b ANY,
** c ANY,
** d ANY,
** lsm1_key BLOB HIDDEN,
** lsm1_value BLOB HIDDEN
** ) WITHOUT ROWID;
**
**
**
** INTERNALS
**
** The key encoding for BLOB and TEXT is just a copy of the blob or text.
** UTF-8 is used for text. The key encoding for UINT is the variable-length
** integer format at https://sqlite.org/src4/doc/trunk/www/varint.wiki.
**
** The values are encoded as a single blob (since that is what lsm stores as
** its content). There is a "type integer" followed by "content" for each
** value, alternating back and forth. The content might be empty.
**
** TYPE1 CONTENT1 TYPE2 CONTENT2 TYPE3 CONTENT3 ....
**
** Each "type integer" is encoded as a variable-length integer in the
** format of the link above. Let the type integer be T. The actual
** datatype is an integer 0-5 equal to T%6. Values 1 through 5 correspond
** to SQLITE_INTEGER through SQLITE_NULL. The size of the content in bytes
** is T/6. Type value 0 means that the value is an integer whose actual
** values is T/6 and there is no content. The type-value-0 integer format
** only works for integers in the range of 0 through 40.
**
** There is no content for NULL or type-0 integers. For BLOB and TEXT
** values, the content is the blob data or the UTF-8 text data. For
** non-negative integers X, the content is a variable-length integer X*2.
** For negative integers Y, the content is varaible-length integer (1-Y)*2+1.
** For FLOAT values, the content is the IEEE754 floating point value in
** native byte-order. This means that FLOAT values will be corrupted when
** database file is moved between big-endian and little-endian machines.

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

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

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

** This is an in-memory VFS implementation. The application supplies

**
** Because there is no place to store journals and no good way to lock

** Because there is place to store a rollback or wal journal, the database

** "memvfs");
**
** The ptr= and sz= query parameters are required or the open will fail.
** The ptr= parameter gives the memory address of the buffer holding the

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

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

**
** SWARMVTAB
**
** LEGACY SYNTAX:
**
** A "swarmvtab" virtual table is created similarly to a unionvtab table:
**
** CREATE VIRTUAL TABLE <name>
** USING swarmvtab(<sql-statement>, <callback>);
**
** The difference is that for a swarmvtab table, the first column returned
** by the <sql statement> must return a path or URI that can be used to open
** the database file containing the source table. The <callback> option
** is optional. If included, it is the name of an application-defined
** SQL function that is invoked with the URI of the file, if the file
** does not already exist on disk when required by swarmvtab.
**
** NEW SYNTAX:
**
** Using the new syntax, a swarmvtab table is created with:
**
** CREATE VIRTUAL TABLE <name> USING swarmvtab(
** <sql-statement> [, <options>]
** );
**
** where valid <options> are:
**
** missing=<udf-function-name>
** openclose=<udf-function-name>
** maxopen=<integer>
** <sql-parameter>=<text-value>
**
** The <sql-statement> must return the same 4 columns as for a swarmvtab
** table in legacy mode. However, it may also return a 5th column - the
** "context" column. The text value returned in this column is not used
** at all by the swarmvtab implementation, except that it is passed as
** an additional argument to the two UDF functions that may be invoked
** (see below).
**
** The "missing" option, if present, specifies the name of an SQL UDF
** function to be invoked if a database file is not already present on
** disk when required by swarmvtab. If the <sql-statement> did not provide
** a context column, it is invoked as:
**
** SELECT <missing-udf>(<database filename/uri>);
**
** Or, if there was a context column:
**
** SELECT <missing-udf>(<database filename/uri>, <context>);
**
** The "openclose" option may also specify a UDF function. This function
** is invoked right before swarmvtab opens a database, and right after
** it closes one. The first argument - or first two arguments, if
** <sql-statement> supplied the context column - is the same as for
** the "missing" UDF. Following this, the UDF is passed integer value
** 0 before a db is opened, and 1 right after it is closed. If both
** a missing and openclose UDF is supplied, the application should expect
** the following sequence of calls (for a single database):
**
** SELECT <openclose-udf>(<db filename>, <context>, 0);
** if( db not already on disk ){
** SELECT <missing-udf>(<db filename>, <context>);
** }
** ... swarmvtab uses database ...
** SELECT <openclose-udf>(<db filename>, <context>, 1);
**
** The "maxopen" option is used to configure the maximum number of
** database files swarmvtab will hold open simultaneously (default 9).
**
** If an option name begins with a ":" character, then it is assumed
** to be an SQL parameter. In this case, the specified text value is
** bound to the same variable of the <sql-statement> before it is
** executed. It is an error of the named SQL parameter does not exist.
** For example:
**
** CREATE VIRTUAL TABLE swarm USING swarmvtab(
** 'SELECT :path || localfile, tbl, min, max FROM swarmdir',
** :path='/home/user/databases/'
** missing='missing_func'
** );
