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.
The makefiles also require AWK.
## Source Code Tour
Most of the core source files are in the **src/** subdirectory. But
src/ also contains files used to build the "testfixture" test harness;
those file all begin with "test". And src/ contains the "shell.c" file
which is the main program for the "sqlite3.exe" command-line shell and
the "tclsqlite.c" file which implements the bindings to SQLite from the
Tcl programming language. (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.
There are other test suites for SQLite (see
[How SQLite Is Tested](http://www.sqlite.org/testing.html))
but those other test suites are
in separate source repositories.
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_source".
The "target_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 SHA1 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 a
template for generating its parser. A generic template is in tool/lempar.c,
but SQLite uses a slightly modified template found in src/lempar.c.
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.awk
AWK 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
AWK script at ./mkopcodeh.awk does this scan and generates opcodes.h.
A second AWK script, ./mkopcodec.awk, 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 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 100K 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 five other files
named **sqlite3-1.c**, **sqlite3-2.c**, ..., **sqlite3-5.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/vdbe.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).
Unfortunately, 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 SQLite implementation.
Key files:
* **sqlite3.h** - 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.
* **parse.y** - This file describes the LALR(1) grammer that SQLite uses
to parse SQL statements, and the actions that are taken at each stop
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 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.
* **pager.c** - This file contains the "pager" implementation, the
module that implements transactions.
* **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.

This directory contains components use to build an autoconf-ready package
of the SQLite amalgamation: sqlite-autoconf-30XXXXXX.tar.gz
This file describes how to use the files in this directory to create a new
version of the "autoconf-amalgamation" package.
1. The following files should have executable permission:
chmod 755 install-sh
chmod 755 missing
chmod 755 depcomp
chmod 755 config.sub
chmod 755 config.guess
2. Copy new versions of the following SQLite files into this directory:
sqlite3.c
sqlite3.h
sqlite3ext.h
sqlite3.1
sqlite3.pc.in
shell.c
3. Update the SQLite version number in the AC_INIT macro in file
configure.ac:
AC_INIT(sqlite, 3.6.3, http://www.sqlite.org)
4. Run the following commands to push the version number change through
to the generated files.
aclocal
autoconf
automake
5. Create the tclsqlite3.c file in the tea/generic directory. As follows:
mkdir -p tea/generic
echo "#ifdef USE_SYSTEM_SQLITE" > tea/generic/tclsqlite3.c
echo "# include <sqlite3.h>" >> tea/generic/tclsqlite3.c
echo "#else" >> tea/generic/tclsqlite3.c
echo "#include \"../../sqlite3.c\"" >> tea/generic/tclsqlite3.c
echo "#endif" >> tea/generic/tclsqlite3.c
cat ../src/tclsqlite.c >> tea/generic/tclsqlite3.c
6. Update the SQLite version in the AC_INIT macro in file tea/configure.in:
AC_INIT([sqlite], [3.6.3])
7. From the 'tea' directory, run the following commands:
autoconf
rm -rf autom4te.cache
8. Run "./configure && make dist". This builds a distribution package
named something like "sqlite-3.6.3.tar.gz". Rename to
"sqlite-amalgamation-3.6.3.tar.gz" and use.
To build the autoconf amalgamation, run from the top-level:
./configure
make amalgamation-tarball
The amalgamation-tarball target (also available in "main.mk") runs the
script tool/mkautoconfamal.sh which does the work. Refer to that script
for details.

Activate the user authentication logic by including the
ext/userauth/userauth.c source code file in the build and
adding the -DSQLITE_USER_AUTHENTICATION compile-time option.
The ext/userauth/sqlite3userauth.h header file is available to
applications to define the interface.
When using the SQLite amalgamation, it is sufficient to append
the ext/userauth/userauth.c source file onto the end of the
amalgamation.
The following new APIs are available when user authentication is
activated:
int sqlite3_user_authenticate(
sqlite3 *db, /* The database connection */
const char *zUsername, /* Username */
const char *aPW, /* Password or credentials */
int nPW /* Number of bytes in aPW[] */
);
int sqlite3_user_add(
sqlite3 *db, /* Database connection */
const char *zUsername, /* Username to be added */
const char *aPW, /* Password or credentials */
int nPW, /* Number of bytes in aPW[] */
int isAdmin /* True to give new user admin privilege */
);
int sqlite3_user_change(
sqlite3 *db, /* Database connection */
const char *zUsername, /* Username to change */
const void *aPW, /* Modified password or credentials */
int nPW, /* Number of bytes in aPW[] */
int isAdmin /* Modified admin privilege for the user */
);
int sqlite3_user_delete(
sqlite3 *db, /* Database connection */
const char *zUsername /* Username to remove */
);
With this extension, a database can be marked as requiring authentication.
By default a database does not require authentication.
The sqlite3_open(), sqlite3_open16(), and sqlite3_open_v2() interfaces
work as before: they open a new database connection. However, if the
database being opened requires authentication, then attempts to read
or write from the database will fail with an SQLITE_AUTH error until
after sqlite3_user_authenticate() has been called successfully. The
sqlite3_user_authenticate() call will return SQLITE_OK if the
authentication credentials are accepted and SQLITE_ERROR if not.
Calling sqlite3_user_authenticate() on a no-authentication-required
database connection is a harmless no-op.
If the database is encrypted, then sqlite3_key_v2() must be called first,
with the correct decryption key, prior to invoking sqlite3_user_authenticate().
To recapitulate: When opening an existing unencrypted authentication-
required database, the call sequence is:
sqlite3_open_v2()
sqlite3_user_authenticate();
/* Database is now usable */
To open an existing, encrypted, authentication-required database, the
call sequence is:
sqlite3_open_v2();
sqlite3_key_v2();
sqlite3_user_authenticate();
/* Database is now usable */
When opening a no-authentication-required database, the database
connection is treated as if it was authenticated as an admin user.
When ATTACH-ing new database files to a connection, each newly attached
database that is an authentication-required database is checked using
the same username and password as supplied to the main database. If that
check fails, then the ATTACH command fails with an SQLITE_AUTH error.
The sqlite3_user_add() interface can be used (by an admin user only)
to create a new user. When called on a no-authentication-required
database and when A is true, the sqlite3_user_add(D,U,P,N,A) routine
converts the database into an authentication-required database and
logs in the database connection D as user U with password P,N.
To convert a no-authentication-required database into an authentication-
required database, the isAdmin parameter must be true. If
sqlite3_user_add(D,U,P,N,A) is called on a no-authentication-required
database and A is false, then the call fails with an SQLITE_AUTH error.
Any call to sqlite3_user_add() by a non-admin user results in an error.
Hence, to create a new, unencrypted, authentication-required database,
the call sequence is:
sqlite3_open_v2();
sqlite3_user_add();
And to create a new, encrypted, authentication-required database, the call
sequence is:
sqlite3_open_v2();
sqlite3_key_v2();
sqlite3_user_add();
The sqlite3_user_delete() interface can be used (by an admin user only)
to delete a user. The currently logged-in user cannot be deleted,
which guarantees that there is always an admin user and hence that
the database cannot be converted into a no-authentication-required
database.
The sqlite3_user_change() interface can be used to change a users
login credentials or admin privilege. Any user can change their own
password. Only an admin user can change another users login
credentials or admin privilege setting. No user may change their own
admin privilege setting.
The sqlite3_set_authorizer() callback is modified to take a 7th parameter
which is the username of the currently logged in user, or NULL for a
no-authentication-required database.
-----------------------------------------------------------------------------
Implementation notes:
An authentication-required database is identified by the presence of a
new table:
CREATE TABLE sqlite_user(
uname TEXT PRIMARY KEY,
isAdmin BOOLEAN,
pw BLOB
) WITHOUT ROWID;
The sqlite_user table is inaccessible (unreadable and unwriteable) to
non-admin users and is read-only for admin users. However, if the same
database file is opened by a version of SQLite that omits
the -DSQLITE_USER_AUTHENTICATION compile-time option, then the sqlite_user
table will be readable by anybody and writeable by anybody if
the "PRAGMA writable_schema=ON" statement is run first.
The sqlite_user.pw field is encoded by a built-in SQL function
"sqlite_crypt(X,Y)". The two arguments are both BLOBs. The first argument
is the plaintext password supplied to the sqlite3_user_authenticate()
interface. The second argument is the sqlite_user.pw value and is supplied
so that the function can extract the "salt" used by the password encoder.
The result of sqlite_crypt(X,Y) is another blob which is the value that
ends up being stored in sqlite_user.pw. To verify credentials X supplied
by the sqlite3_user_authenticate() routine, SQLite runs:
sqlite_user.pw == sqlite_crypt(X, sqlite_user.pw)
To compute an appropriate sqlite_user.pw value from a new or modified
password X, sqlite_crypt(X,NULL) is run. A new random salt is selected
when the second argument is NULL.
The built-in version of of sqlite_crypt() uses a simple Ceasar-cypher
which prevents passwords from being revealed by searching the raw database
for ASCII text, but is otherwise trivally broken. For better password
security, the database should be encrypted using the SQLite Encryption
Extension or similar technology. Or, the application can use the
sqlite3_create_function() interface to provide an alternative
implementation of sqlite_crypt() that computes a stronger password hash,
perhaps using a cryptographic hash function like SHA1.
