@ -22,68 +52,458 @@ _go-sqlite3_ is *cgo* package.
If you want to build your app using go-sqlite3, you need gcc.
However, after you have built and installed _go-sqlite3_ with `go install github.com/mattn/go-sqlite3` (which requires gcc), you can build your app without relying on gcc in future.
Documentation

# Connection String
* Want to build go-sqlite3 with libsqlite3 on my linux.
When creating a new SQLite database or connection to an existing one, with the file name additional options can be given.
This is also known as a DSN string. (Data Source Name).
Use `go build --tags "libsqlite3 linux"`
Options are append after the filename of the SQLite database.
The database filename and options are seperated by an `?` (Question Mark).
* Want to build go-sqlite3 with libsqlite3 on OS X.
This also applies when using an in-memory database instead of a file.
Install sqlite3 from homebrew: `brew install sqlite3`
Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
Use `go build --tags "libsqlite3 darwin"`
This library supports dsn options of SQLite itself and provides additional options.
* Want to build go-sqlite3 with icu extension.
Boolean values can be one of:
* `0` `no` `false` `off`
* `1` `yes` `true` `on`
Use `go build --tags "icu"`

# Features
This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build `tags`.
[Click here for more information about build tags / constraints.](https://golang.org/pkg/go/build/#hdr-Build_Constraints)
### Usage
If you wish to build this library with additional extensions / features.
Use the following command.
```bash
go build --tags "<FEATURE>"
```
For available features see the extension list.
When using multiple build tags, all the different tags should be space delimted.
Example:
```bash
go build --tags "icu json1 fts5 secure_delete"
```
### Feature / Extension List
| Extension | Build Tag | Description |
|-----------|-----------|-------------|
| Additional Statistics | sqlite_stat4 | This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table.<br><br>The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.<br><br>SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.<br><br>The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |
| Allow URI Authority | sqlite_allow_uri_authority | URI filenames normally throws an error if the authority section is not either empty or "localhost".<br><br>However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way |
| App Armor | sqlite_app_armor | When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. <br><br>App Armor is not available under `Windows`. |
| Disable Load Extensions | sqlite_omit_load_extension | Loading of external extensions is enabled by default.<br><br>To disable extension loading add the build tag `sqlite_omit_load_extension`. |
| Foreign Keys | sqlite_foreign_keys | This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections.<br><br>Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma.<br><br>Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default |
| Full Auto Vacuum | sqlite_vacuum_full | Set the default auto vacuum to full |
| Incremental Auto Vacuum | sqlite_vacuum_incr | Set the default auto vacuum to incremental |
| Full Text Search Engine | sqlite_fts5 | When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically |
| International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build |
| Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. <ul><li>PRAGMA function_list</li><li>PRAGMA module_list</li><li>PRAGMA pragma_list</li></ul> |
| JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically |
| Secure Delete | sqlite_secure_delete | This compile-time option changes the default setting of the secure_delete pragma.<br><br>When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.<br><br>The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.<br><br>On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information |
| Secure Delete (FAST) | sqlite_secure_delete_fast | For more information see [PRAGMA secure_delete](https://www.sqlite.org/pragma.html#pragma_secure_delete) |
| Tracing / Debug | sqlite_trace | Activate trace functions |
| User Authentication | sqlite_userauth | SQLite User Authentication see [User Authentication](#user-authentication) for more information. |

# User Authentication
This package supports the SQLite User Authentication module.
## Compile
To use the User authentication module the package has to be compiled with the tag `sqlite_userauth`. See [Features](#features).
## Usage
### Create protected database
To create a database protected by user authentication provide the following argument to the connection string `_auth`.
This will enable user authentication within the database. This option however requires two additional arguments:
- `_auth_user`
- `_auth_pass`
When `_auth` is present on the connection string user authentication will be enabled and the provided user will be created
as an `admin` user. After initial creation, the parameter `_auth` has no effect anymore and can be omitted from the connection string.
Example connection string:
Create an user authentication database with user `admin` and password `admin`.
`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin`
Create an user authentication database with user `admin` and password `admin` and use `SHA1` for the password encoding.
`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin&_auth_crypt=sha1`
### Password Encoding
The passwords within the user authentication module of SQLite are encoded with the SQLite function `sqlite_cryp`.
This function uses a ceasar-cypher which is quite insecure.
This library provides several additional password encoders which can be configured through the connection string.
The password cypher can be configured with the key `_auth_crypt`. And if the configured password encoder also requires an
salt this can be configured with `_auth_salt`.
#### Available Encoders
- SHA1
- SSHA1 (Salted SHA1)
- SHA256
- SSHA256 (salted SHA256)
- SHA384
- SSHA384 (salted SHA384)
- SHA512
- SSHA512 (salted SHA512)
### Restrictions
Operations on the database regarding to user management can only be preformed by an administrator user.
### Support
The user authentication supports two kinds of users
- administrators
- regular users
### User Management
User management can be done by directly using the `*SQLiteConn` or by SQL.
#### SQL
The following sql functions are available for user management.
| Function | Arguments | Description |
|----------|-----------|-------------|
| `authenticate` | username `string`, password `string` | Will authenticate an user, this is done by the connection; and should not be used manually. |
| `auth_user_add` | username `string`, password `string`, admin `int` | This function will add an user to the database.<br>if the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators. |
| `auth_user_change` | username `string`, password `string`, admin `int` | Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. |
| `authUserDelete` | username `string` | Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining. |
These functions will return an integer.
- 0 (SQLITE_OK)
- 23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges
##### Examples
```sql
// Autheticate user
// Create Admin User
SELECT auth_user_add('admin2', 'admin2', 1);
// Change password for user
SELECT auth_user_change('user', 'userpassword', 0);
// Delete user
SELECT user_delete('user');
```
#### *SQLiteConn
The following functions are available for User authentication from the `*SQLiteConn`.
| Function | Description |
|----------|-------------|
| `Authenticate(username, password string) error` | Authenticate user |
| `AuthUserAdd(username, password string, admin bool) error` | Add user |
| `AuthUserChange(username, password string, admin bool) error` | Modify user |
| `AuthUserDelete(username string) error` | Delete user |
### Attached database
When using attached databases. SQLite will use the authentication from the `main` database for the attached database(s).

Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.
* Can I use this in multiple routines concurrently?
- Can I use this in multiple routines concurrently?
Yes for readonly. But, No for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209), [#274](https://github.com/mattn/go-sqlite3/issues/274).
* Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
- Why I'm getting `no such table` error?
Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
Each connection to :memory: opens a brand new in-memory sql database, so if
the stdlib's sql engine happens to open another connection and you've only
specified ":memory:", that connection will see a brand new database. A
workaround is to use "file::memory:?mode=memory&cache=shared". Every
connection to this string will point to the same in-memory database. See
[#204](https://github.com/mattn/go-sqlite3/issues/204) for more info.

** These routines provide access to the set of SQL language keywords
** recognized by SQLite. Applications can uses these routines to determine
** whether or not a specific identifier needs to be escaped (for example,
** by enclosing in double-quotes) so as not to confuse the parser.
**
** The sqlite3_keyword_count() interface returns the number of distinct
** keywords understood by SQLite.
**
** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
** makes *Z point to that keyword expressed as UTF8 and writes the number
** of bytes in the keyword into *L. The string that *Z points to is not
** zero-terminated. The sqlite3_keyword_name(N,Z,L) routine returns
** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
** or L are NULL or invalid pointers then calls to
** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
**
** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
** if it is and zero if not.
**
** The parser used by SQLite is forgiving. It is often possible to use
** a keyword as an identifier as long as such use does not result in a
** parsing ambiguity. For example, the statement
** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
** creates a new table named "BEGIN" with three columns named
** "REPLACE", "PRAGMA", and "END". Nevertheless, best practice is to avoid
** using keywords as identifiers. Common techniques used to avoid keyword
** name collisions include:
** <ul>
** <li> Put all identifier names inside double-quotes. This is the official
** SQL way to escape identifier names.
** <li> Put identifier names inside &#91;...&#93;. This is not standard SQL,
** but it is what SQL Server does and so lots of programmers use this
** technique.
** <li> Begin every identifier with the letter "Z" as no SQL keywords start
** with "Z".
** <li> Include a digit somewhere in every identifier name.
** </ul>
**
** Note that the number of keywords understood by SQLite can depend on
** compile-time options. For example, "VACUUM" is not a keyword if
** SQLite is compiled with the [-DSQLITE_OMIT_VACUUM] option. Also,
** new keywords may be added to future releases of SQLite.

// This file provides several different implementations for the
// default embedded sqlite_crypt function.
// This function is uses a ceasar-cypher by default
// and is used within the UserAuthentication module to encode
// the password.
//
// The provided functions can be used as an overload to the sqlite_crypt
// function through the use of the RegisterFunc on the connection.
//
// Because the functions can serv a purpose to an end-user
// without using the UserAuthentication module
// the functions are default compiled in.
//
// From SQLITE3 - user-auth.txt
// 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.
