<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.
................................................................................
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
................................................................................

  *  **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.

<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.

## Version Control

SQLite sources are managed using the
[Fossil](https://www.fossil-scm.org/), a distributed version control system
that was specifically designed and written to support SQLite development.
The [Fossil repository](https://sqlite.org/src/timeline) contains the urtext.

If you are reading this on GitHub or some other Git repository or service,


then you are looking at a mirror.  The names of check-ins and
other artifacts in a Git mirror are different from the official
names for those objects.  The offical names for check-ins are
found in a footer on the check-in comment for authorized mirrors.
The official check-in name can also be seen in the `manifest.uuid` file
in the root of the tree.  Always use the official name, not  the
Git-name, when communicating about an SQLite check-in.

If you pulled your SQLite source code from a secondary source and want to
verify its integrity, there are hints on how to do that in the
[Verifying Code Authenticity](#vauth) section below.

## Obtaining The Code




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 in place of "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.
................................................................................
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.



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
................................................................................

  *  **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.

<a name="vauth"></a>
## Verifying Code Authenticity

The `manifest` file at the root directory of the source tree
contains either a SHA3-256 hash (for newer files) or a SHA1 hash (for 
older files) for every source file in the repository.
The SHA3-256 hash of the `manifest`
file itself is the official name of the version of the source tree that you
have. The `manifest.uuid` file should contain the SHA3-256 hash of the
`manifest` file. If all of the above hash comparisons are correct, then
you can be confident that your source tree is authentic and unadulterated.

The format of the `manifest` file should be mostly self-explanatory, but
if you want details, they are available
[here](https://fossil-scm.org/fossil/doc/trunk/www/fileformat.wiki#manifest).

# exits with 0.  Otherwise, it exits with 1.
#
# The plan is that this can be called by configure scripts if you

Begin Concurrent
================

## Overview

Usually, SQLite allows at most one writer to proceed concurrently. The
BEGIN CONCURRENT enhancement allows multiple writers to process write
transactions simultanously if the database is in "wal" or "wal2" mode,
although the system still serializes COMMIT commands.

When a write-transaction is opened with "BEGIN CONCURRENT", actually 
locking the database is deferred until a COMMIT is executed. This means
that any number of transactions started with BEGIN CONCURRENT may proceed
concurrently. The system uses optimistic page-level-locking to prevent
conflicting concurrent transactions from being committed.

When a BEGIN CONCURRENT transaction is committed, the system checks whether 
or not any of the database pages that the transaction has read have been
modified since the BEGIN CONCURRENT was opened. In other words - it asks 
if the transaction being committed operates on a different set of data than
all other concurrently executing transactions. If the answer is "yes, this
transaction did not read or modify any data modified by any concurrent
transaction", then the transaction is committed as normal. Otherwise, if the
transaction does conflict, it cannot be committed and an SQLITE&#95;BUSY&#95;SNAPSHOT
error is returned. At this point, all the client can do is ROLLBACK the
transaction.

If SQLITE&#95;BUSY&#95;SNAPSHOT is returned, messages are output via the sqlite3&#95;log
mechanism indicating the page and table or index on which the conflict
occurred. This can be useful when optimizing concurrency.

## Application Programming Notes

In order to serialize COMMIT processing, SQLite takes a lock on the database
as part of each COMMIT command and releases it before returning. At most one
writer may hold this lock at any one time. If a writer cannot obtain the lock,
it uses SQLite's busy-handler to pause and retry for a while:

  <a href=https://www.sqlite.org/c3ref/busy_handler.html>
      https://www.sqlite.org/c3ref/busy_handler.html
  </a>

If there is significant contention for the writer lock, this mechanism can be
inefficient. In this case it is better for the application to use a mutex or
some other mechanism that supports blocking to ensure that at most one writer
is attempting to COMMIT a BEGIN CONCURRENT transaction at a time. This is
usually easier if all writers are part of the same operating system process.

If all database clients (readers and writers) are located in the same OS
process, and if that OS is a Unix variant, then it can be more efficient to
the built-in VFS "unix-excl" instead of the default "unix". This is because it
uses more efficient locking primitives.

The key to maximizing concurrency using BEGIN CONCURRENT is to ensure that
there are a large number of non-conflicting transactions. In SQLite, each
table and each index is stored as a separate b-tree, each of which is
distributed over a discrete set of database pages. This means that:

  * Two transactions that write to different sets of tables never 
    conflict, and that

  * Two transactions that write to the same tables or indexes only 
    conflict if the values of the keys (either primary keys or indexed 
    rows) are fairly close together. For example, given a large 
    table with the schema:

      <pre>     CREATE TABLE t1(a INTEGER PRIMARY KEY, b BLOB);</pre>

    writing two rows with adjacent values for "a" probably will cause a
    conflict (as the two keys are stored on the same page), but writing two
    rows with vastly different values for "a" will not (as the keys will likly
    be stored on different pages).

Note that, in SQLite, if values are not explicitly supplied for an INTEGER
PRIMARY KEY, as for example in:

>
     INSERT INTO t1(b) VALUES(&lt;blob-value>);

then monotonically increasing values are assigned automatically. This is
terrible for concurrency, as it all but ensures that all new rows are 
added to the same database page. In such situations, it is better to
explicitly assign random values to INTEGER PRIMARY KEY fields.

This problem also comes up for non-WITHOUT ROWID tables that do not have an
explicit INTEGER PRIMARY KEY column. In these cases each table has an implicit
INTEGER PRIMARY KEY column that is assigned increasing values, leading to the
same problem as omitting to assign a value to an explicit INTEGER PRIMARY KEY
column.

For both explicit and implicit INTEGER PRIMARY KEYs, it is possible to have
SQLite assign values at random (instead of the monotonically increasing
values) by writing a row with a rowid equal to the largest possible signed
64-bit integer to the table. For example:

     INSERT INTO t1(a) VALUES(9223372036854775807);

Applications should take care not to malfunction due to the presence of such
rows.

The nature of some types of indexes, for example indexes on timestamp fields,
can also cause problems (as concurrent transactions may assign similar
timestamps that will be stored on the same db page to new records). In these
cases the database schema may need to be rethought to increase the concurrency
provided by page-level-locking.

The precedence of a grammar rule is equal to the precedence of the
left-most terminal symbol in the rule for which a precedence is

you want to precedence of a grammar rule to be something different,
you can specify an alternative precedence symbol by putting the
symbol in square braces after the period at the end of the rule and
before any C-code.  For example:</p>

# The new-security-options branch

## The problem that the [new-security-options](/timeline?r=new-security-options) branch tries to solve

An attacker might modify the schema of an SQLite database by adding
structures that cause code to run when some other application opens and
reads the database.  For example, the attacker might replace a table
definition with a view.  Or the attacker might add triggers to tables
or views, or add new CHECK constraints or generated columns or indexes
with expressions in the index list or in the WHERE clause.  If the
added features invoke SQL functions or virtual tables with side effects,
that might cause harm to the system if run by a high-privilege victim.
Or, the added features might exfiltrate information if the database is
read by a high-privilege victim.

The changes in this branch strive to make it easier for high-privilege
applications to safely read SQLite database files that might have been
maliciously corrupted by an attacker.

## Overview of changes in [new-security-options](/timeline?r=new-security-options)

The basic idea is to tag every SQL function and virtual table with one
of three risk levels:

  1.  Innocuous
  2.  Normal
  3.  Direct-Only

Innocuous functions/vtabs are safe and can be used at any time.
Direct-only elements, in contrast, might have cause side-effects and
should only be used from top-level SQL, not from within triggers or views nor
in elements of the schema such as CHECK constraint, DEFAULT values, 
generated columns, index expressions, or in the WHERE clause of a 
partial index that are potentially under the control of an attacker.
Normal elements behave like Innocuous if TRUSTED\_SCHEMA=on
and behave like direct-only if TRUSTED\_SCHEMA=off.

Application-defined functions and virtual tables go in as Normal unless
the application takes deliberate steps to change the risk level.

For backwards compatibility, the default is TRUSTED\_SCHEMA=on.  Documentation
will be updated to recommend applications turn TRUSTED\_SCHEMA to off.

An innocuous function or virtual table is one that can only read content
from the database file in which it resides, and can only alter the database
in which it resides.  Most SQL functions are innocuous.  For example, there
is no harm in an attacker running the abs() function.

Direct-only elements that have side-effects that go outside the database file
in which it lives, or return information from outside of the database file.
Examples of direct-only elements include:

  1.  The fts3\_tokenizer() function
  2.  The writefile() function
  3.  The readfile() function
  4.  The zipvfs virtual table
  5.  The csv virtual table

We do not want an attacker to be able to add these kinds of things to
the database schema and possibly trick a high-privilege application 
from performing any of these actions.  Therefore, functions and vtabs
with side-effects are marked as Direct-Only.

Legacy applications might add other risky functions or vtabs.  Those will
go in as "Normal" by default.  For optimal security, we want those risky
app-defined functions and vtabs to be direct-only, but making that the
default might break some legacy applications.  Hence, all app-defined
functions and vtabs go in as Normal, but the application can switch them
over to "Direct-Only" behavior using a single pragma.

The restrictions on the use of functions and virtual tables do not apply
to TEMP.  A TEMP VIEW or a TEMP TRIGGER can use any valid SQL function
or virtual table.  The idea is that TEMP views and triggers must be
directly created by the application and are thus under the control of the
application.  TEMP views and triggers cannot be created by an attacker who
corrupts the schema of a persistent database file.  Hence TEMP views and
triggers are safe.

## Specific changes

  1.  New sqlite3\_db\_config() option SQLITE\_DBCONFIG\_TRUSTED\_SCHEMA for
      turning TRUSTED\_SCHEMA on and off.  It defaults to ON.

  2.  Compile-time option -DSQLITE\_TRUSTED\_SCHEMA=0 causes the default
      TRUSTED\_SCHEMA setting to be off.

  3.  New pragma "PRAGMA trusted\_schema=(ON\|OFF);".  This provides access
      to the TRUSTED_SCHEMA setting for application coded using scripting
      languages or other secondary languages where they are unable to make
      calls to sqlite3\_db\_config().

  4.  New options for the "enc" parameter to sqlite3\_create\_function() and
      its kin:
      <ol type="a">
      <li>  _SQLITE\_INNOCUOUS_  &rarr; tags the new functions as Innocuous
      <li>  _SQLITE\_DIRECTONLY_ &rarr; tags the new functions as Direct-Only
      </ol>

  5.  New options to sqlite3\_vtab\_config():
      <ol type="a">
      <li>  _SQLITE\_VTAB\_INNOCUOUS_   &rarr; tags the vtab as Innocuous
      <li>  _SQLITE\_VTAB\_DIRECTONLY_  &rarr; tags the vtab as Direct-Only
      </ol>

  6.  Change many of the functions and virtual tables in the SQLite source
      tree to use one of the tags above.

  7.  Enhanced PRAGMA function\_list and virtual-table "pragma\_function\_list"
      with additional columns.  The columns now are:
      <ul>
      <li> _name_      &rarr;  Name of the function
      <li> _builtin_   &rarr;  1 for built-in functions.  0 otherwise.
      <li> _type_      &rarr;  's'=Scalar, 'a'=Aggregate, 'w'=Window
      <li> _enc_       &rarr;  'utf8', 'utf16le', or 'utf16be'
      <li> _narg_      &rarr;  number of argument
      <li> _flags_     &rarr;  Bitmask of SQLITE\_INNOCUOUS, SQLITE\_DIRECTONLY,
                               SQLITE\_DETERMINISTIC, SQLITE\_SUBTYPE, and
                               SQLITE\_FUNC\_INTERNAL flags.
      </ul>
      <p>The last four columns are new.

  8.  The function\_list PRAGMA now also shows all entries for each function.
      So, for example, if a function can take either 2 or 3 arguments,
      there are separate rows for the 2-argument and 3-argument versions of
      the function.

## Additional Notes

The function_list enhancements allow the application to query the set
of SQL functions that meet various criteria.  For example, to see all
SQL functions that are never allowed to be used in the schema or in
trigger or views:

~~~
    SELECT DISTINCT name FROM pragma_function_list
     WHERE (flags & 0x80000)!=0
     ORDER BY name;
~~~

Doing the same is not possible for virtual tables, as a virtual table
might be Innocuous, Normal, or Direct-Only depending on the arguments
passed into the xConnect method.

# Wal-Mode Blocking Locks

On some Unix-like systems, SQLite may be configured to use POSIX blocking locks
by:

  * building the library with SQLITE\_ENABLE\_SETLK\_TIMEOUT defined, and 
  * configuring a timeout in ms using the sqlite3\_busy\_timeout() API.

Blocking locks may be advantageous as (a) waiting database clients do not
need to continuously poll the database lock, and (b) using blocking locks
facilitates transfer of OS priority between processes when a high priority
process is blocked by a lower priority one.

Only read/write clients use blocking locks. Clients that have read-only access
to the \*-shm file nevery use blocking locks.

Threads or processes that access a single database at a time never deadlock as
a result of blocking database locks. But it is of course possible for threads
that lock multiple databases simultaneously to do so. In most cases the OS will
detect the deadlock and return an error.

## Wal Recovery

Wal database "recovery" is a process required when the number of connected
database clients changes from zero to one. In this case, a client is 
considered to connect to the database when it first reads data from it.
Before recovery commences, an exclusive WRITER lock is taken. 

Without blocking locks, if two clients attempt recovery simultaneously, one
fails to obtain the WRITER lock and either invokes the busy-handler callback or
returns SQLITE\_BUSY to the user. With blocking locks configured, the second
client blocks on the WRITER lock.

## Database Readers

Usually, read-only are not blocked by any other database clients, so they 
have no need of blocking locks.

If a read-only transaction is being opened on a snapshot, the CHECKPOINTER
lock is required briefly as part of opening the transaction (to check that a
checkpointer is not currently overwriting the snapshot being opened). A
blocking lock is used to obtain the CHECKPOINTER lock in this case. A snapshot
opener may therefore block on and transfer priority to a checkpointer in some
cases.

## Database Writers

A database writer must obtain the exclusive WRITER lock. It uses a blocking
lock to do so if any of the following are true:

  * the transaction is an implicit one consisting of a single DML or DDL
    statement, or
  * the transaction is opened using BEGIN IMMEDIATE or BEGIN EXCLUSIVE, or
  * the first SQL statement executed following the BEGIN command is a DML or
    DDL statement (not a read-only statement like a SELECT).

In other words, in all cases except when an open read-transaction is upgraded
to a write-transaction. In that case a non-blocking lock is used.

## Database Checkpointers

Database checkpointers takes the following locks, in order:

  * The exclusive CHECKPOINTER lock.
  * The exclusive WRITER lock (FULL, RESTART and TRUNCATE only).
  * Exclusive lock on read-mark slots 1-N. These are immediately released after being taken.
  * Exclusive lock on read-mark 0.
  * Exclusive lock on read-mark slots 1-N again. These are immediately released
    after being taken (RESTART and TRUNCATE only).

All of the above use blocking locks.

## Summary

With blocking locks configured, the only cases in which clients should see an
SQLITE\_BUSY error are:

  * if the OS does not grant a blocking lock before the configured timeout
    expires, and
  * when an open read-transaction is upgraded to a write-transaction.

In all other cases the blocking locks implementation should prevent clients
from having to handle SQLITE\_BUSY errors and facilitate appropriate transfer
of priorities between competing clients.

Clients that lock multiple databases simultaneously must be wary of deadlock.
