# Humane Units [![Build Status](https://travis-ci.org/dustin/go-humanize.svg?branch=master)](https://travis-ci.org/dustin/go-humanize) [![GoDoc](https://godoc.org/github.com/dustin/go-humanize?status.svg)](https://godoc.org/github.com/dustin/go-humanize)
Just a few functions for helping humanize times and sizes.
`go get` it as `github.com/dustin/go-humanize`, import it as
`"github.com/dustin/go-humanize"`, use it as `humanize`.
See [godoc](https://pkg.go.dev/github.com/dustin/go-humanize) for
complete documentation.
## Sizes
This lets you take numbers like `82854982` and convert them to useful
strings like, `83 MB` or `79 MiB` (whichever you prefer).
Example:
```go
fmt.Printf("That file is %s.", humanize.Bytes(82854982)) // That file is 83 MB.
```
## Times
This lets you take a `time.Time` and spit it out in relative terms.
For example, `12 seconds ago` or `3 days from now`.
Example:
```go
fmt.Printf("This was touched %s.", humanize.Time(someTimeInstance)) // This was touched 7 hours ago.
```
Thanks to Kyle Lemons for the time implementation from an IRC
conversation one day. It's pretty neat.
## Ordinals
From a [mailing list discussion][odisc] where a user wanted to be able
to label ordinals.
0 -> 0th
1 -> 1st
2 -> 2nd
3 -> 3rd
4 -> 4th
[...]
Example:
```go
fmt.Printf("You're my %s best friend.", humanize.Ordinal(193)) // You are my 193rd best friend.
```
## Commas
Want to shove commas into numbers? Be my guest.
0 -> 0
100 -> 100
1000 -> 1,000
1000000000 -> 1,000,000,000
-100000 -> -100,000
Example:
```go
fmt.Printf("You owe $%s.\n", humanize.Comma(6582491)) // You owe $6,582,491.
```
## Ftoa
Nicer float64 formatter that removes trailing zeros.
```go
fmt.Printf("%f", 2.24) // 2.240000
fmt.Printf("%s", humanize.Ftoa(2.24)) // 2.24
fmt.Printf("%f", 2.0) // 2.000000
fmt.Printf("%s", humanize.Ftoa(2.0)) // 2
```
## SI notation
Format numbers with [SI notation][sinotation].
Example:
```go
humanize.SI(0.00000000223, "M") // 2.23 nM
```
## English-specific functions
The following functions are in the `humanize/english` subpackage.
### Plurals
Simple English pluralization
```go
english.PluralWord(1, "object", "") // object
english.PluralWord(42, "object", "") // objects
english.PluralWord(2, "bus", "") // buses
english.PluralWord(99, "locus", "loci") // loci
english.Plural(1, "object", "") // 1 object
english.Plural(42, "object", "") // 42 objects
english.Plural(2, "bus", "") // 2 buses
english.Plural(99, "locus", "loci") // 99 loci
```
### Word series
Format comma-separated words lists with conjuctions:
```go
english.WordSeries([]string{"foo"}, "and") // foo
english.WordSeries([]string{"foo", "bar"}, "and") // foo and bar
english.WordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar and baz
english.OxfordWordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar, and baz
```

# Installation
This package can be installed with the `go get` command:
go get github.com/mattn/go-sqlite3
_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.
***Important: because this is a `CGO` enabled package, you are required to set the environment variable `CGO_ENABLED=1` and have a `gcc` compiler present within your path.***
# API Reference
API documentation can be found [here](http://godoc.org/github.com/mattn/go-sqlite3).
Examples can be found under the [examples](./_example) directory.
# Connection String
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 (Data Source Name) string.
Options are append after the filename of the SQLite database.
The database filename and options are separated by an `?` (Question Mark).
Options should be URL-encoded (see [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)).
This also applies when using an in-memory database instead of a file.
Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
This library supports DSN options of SQLite itself and provides additional options.
Boolean values can be one of:
* `0` `no` `false` `off`
* `1` `yes` `true` `on`

# 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](https://golang.org/pkg/go/build/#hdr-Build_Constraints) for more information about build tags / 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 delimited.
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`. |
| Enable Serialization with `libsqlite3` | sqlite_serialize | Serialization and deserialization of a SQLite database is available by default, unless the build tag `libsqlite3` is set.<br><br>To enable this functionality even if `libsqlite3` is set, add the build tag `sqlite_serialize`. |
| 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 |
| Math Functions | sqlite_math_functions | This compile-time option enables built-in scalar math functions. For more information see [Built-In Mathematical SQL Functions](https://www.sqlite.org/lang_mathfunc.html) |
| OS Trace | sqlite_os_trace | This option enables OSTRACE() debug logging. This can be verbose and should not be used in production. |
| Pre Update Hook | sqlite_preupdate_hook | Registers a callback function that is invoked prior to each INSERT, UPDATE, and DELETE operation on a database table. |
| 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. |
| Virtual Tables | sqlite_vtable | SQLite Virtual Tables see [SQLite Official VTABLE Documentation](https://www.sqlite.org/vtab.html) for more information, and a [full example here](https://github.com/mattn/go-sqlite3/tree/master/_example/vtable) |
# Compilation
This package requires the `CGO_ENABLED=1` environment variable if not set by default, and the presence of the `gcc` compiler.
If you need to add additional CFLAGS or LDFLAGS to the build command, and do not want to modify this package, then this can be achieved by using the `CGO_CFLAGS` and `CGO_LDFLAGS` environment variables.
## Android
This package can be compiled for android.
Compile with:
```bash
go build -tags "android"
```
For more information see [#201](https://github.com/mattn/go-sqlite3/issues/201)
# ARM
To compile for `ARM` use the following environment:
```bash
env CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ \
CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 \
go build -v
```
Additional information:
- [#242](https://github.com/mattn/go-sqlite3/issues/242)
- [#504](https://github.com/mattn/go-sqlite3/issues/504)
# Cross Compile
This library can be cross-compiled.
In some cases you are required to the `CC` environment variable with the cross compiler.
## Cross Compiling from macOS
The simplest way to cross compile from macOS is to use [xgo](https://github.com/karalabe/xgo).
Steps:
- Install [musl-cross](https://github.com/FiloSottile/homebrew-musl-cross) (`brew install FiloSottile/musl-cross/musl-cross`).

# Google Cloud Platform
Building on GCP is not possible because Google Cloud Platform does not allow `gcc` to be executed.
Please work only with compiled final binaries.
## Linux
To compile this package on Linux, you must install the development tools for your linux distribution.
To compile under linux use the build tag `linux`.
```bash
go build -tags "linux"
```
If you wish to link directly to libsqlite3 then you can use the `libsqlite3` build tag.
```
go build -tags "libsqlite3 linux"
```
### Alpine
When building in an `alpine` container run the following command before building:
```
apk add --update gcc musl-dev
```
### Fedora
```bash
sudo yum groupinstall "Development Tools" "Development Libraries"
```
### Ubuntu
```bash
sudo apt-get install build-essential
```
## macOS
macOS should have all the tools present to compile this package. If not, install XCode to add all the developers tools.
Required dependency:
```bash
brew install sqlite3
```
For macOS, there is an additional package to install which is required if you wish to build the `icu` extension.
This additional package can be installed with `homebrew`:
```bash
brew upgrade icu4c
```
To compile for macOS on x86:
```bash
go build -tags "darwin amd64"
```
To compile for macOS on ARM chips:
```bash
go build -tags "darwin arm64"
```
If you wish to link directly to libsqlite3, use the `libsqlite3` build tag:
```
# x86
go build -tags "libsqlite3 darwin amd64"
# ARM
go build -tags "libsqlite3 darwin arm64"
```
Additional information:

- [#404](https://github.com/mattn/go-sqlite3/issues/404)
## Windows
To compile this package on Windows, you must have the `gcc` compiler installed.
1) Install a Windows `gcc` toolchain.
2) Add the `bin` folder to the Windows path, if the installer did not do this by default.
3) Open a terminal for the TDM-GCC toolchain, which can be found in the Windows Start menu.
4) Navigate to your project folder and run the `go build ...` command for this package.
For example the TDM-GCC Toolchain can be found [here](https://jmeubank.github.io/tdm-gcc/).
## Errors
- Compile error: `can not be used when making a shared object; recompile with -fPIC`
When receiving a compile time error referencing recompile with `-FPIC` then you
are probably using a hardend system.
You can compile the library on a hardend system with the following command.
```bash
go build -ldflags '-extldflags=-fno-PIC'
```
More details see [#120](https://github.com/mattn/go-sqlite3/issues/120)
- Can't build go-sqlite3 on windows 64bit.
> Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
> See: [#27](https://github.com/mattn/go-sqlite3/issues/27)
- `go get github.com/mattn/go-sqlite3` throws compilation error.
`gcc` throws: `internal compiler error`
Remove the download repository from your disk and try re-install with:
```bash
go install github.com/mattn/go-sqlite3
```
# 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 in 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 strings:
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 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).

# FAQ
- Getting insert error while query is opened.
> You can pass some arguments into the connection string, for example, a URI.
> See: [#39](https://github.com/mattn/go-sqlite3/issues/39)
- Do you want to cross compile? mingw on Linux or Mac?
> See: [#106](https://github.com/mattn/go-sqlite3/issues/106)
> See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
- Want to get time.Time with current locale
Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.
- Can I use this in multiple routines concurrently?
Yes for readonly. But not 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 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:?cache=shared"` (or `"file:foobar?mode=memory&cache=shared"`). Every
connection to this string will point to the same in-memory database.
Note that if the last database connection in the pool closes, the in-memory database is deleted. Make sure the [max idle connection limit](https://golang.org/pkg/database/sql/#DB.SetMaxIdleConns) is > 0, and the [connection lifetime](https://golang.org/pkg/database/sql/#DB.SetConnMaxLifetime) is infinite.

* [#511](https://github.com/mattn/go-sqlite3/issues/511)

* https://www.sqlite.org/inmemorydb.html#sharedmemdb
- Reading from database with large amount of goroutines fails on OSX.
OS X limits OS-wide to not have more than 1000 files open simultaneously by default.
For more information, see [#289](https://github.com/mattn/go-sqlite3/issues/289)
- Trying to execute a `.` (dot) command throws an error.
Error: `Error: near ".": syntax error`
Dot command are part of SQLite3 CLI, not of this library.
You need to implement the feature or call the sqlite3 cli.
More information see [#305](https://github.com/mattn/go-sqlite3/issues/305).
- Error: `database is locked`
When you get a database is locked, please use the following options.
Add to DSN: `cache=shared`
Example:
```go
db, err := sql.Open("sqlite3", "file:locked.sqlite?cache=shared")
```
Next, please set the database connections of the SQL package to 1:
```go
db.SetMaxOpenConns(1)
```
For more information, see [#209](https://github.com/mattn/go-sqlite3/issues/209).

/*
Package sqlite3 provides interface to SQLite3 databases.
This works as a driver for database/sql.
Installation
go get github.com/mattn/go-sqlite3
# Supported Types
Currently, go-sqlite3 supports the following data types.
+------------------------------+
|go | sqlite3 |
|----------|-------------------|
|nil | null |
|int | integer |
|int64 | integer |
|float64 | float |
|bool | integer |
|[]byte | blob |
|string | text |
|time.Time | timestamp/datetime|
+------------------------------+
# SQLite3 Extension
You can write your own extension module for sqlite3. For example, below is an
extension for a Regexp matcher operation.
#include <pcre.h>
#include <string.h>
#include <stdio.h>
#include <sqlite3ext.h>
SQLITE_EXTENSION_INIT1
static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
if (argc >= 2) {
const char *target = (const char *)sqlite3_value_text(argv[1]);
const char *pattern = (const char *)sqlite3_value_text(argv[0]);
const char* errstr = NULL;
int erroff = 0;
int vec[500];
int n, rc;
pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
if (rc <= 0) {
sqlite3_result_error(context, errstr, 0);
return;
}
sqlite3_result_int(context, 1);
}
}
#ifdef _WIN32
__declspec(dllexport)
#endif
int sqlite3_extension_init(sqlite3 *db, char **errmsg,
const sqlite3_api_routines *api) {
SQLITE_EXTENSION_INIT2(api);
return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
(void*)db, regexp_func, NULL, NULL);
}
It needs to be built as a so/dll shared library. And you need to register
the extension module like below.
sql.Register("sqlite3_with_extensions",
&sqlite3.SQLiteDriver{
Extensions: []string{
"sqlite3_mod_regexp",
},
})
Then, you can use this extension.
rows, err := db.Query("select text from mytable where name regexp '^golang'")
# Connection Hook
You can hook and inject your code when the connection is established by setting
ConnectHook to get the SQLiteConn.
sql.Register("sqlite3_with_hook_example",
&sqlite3.SQLiteDriver{
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
sqlite3conn = append(sqlite3conn, conn)
return nil
},
})
You can also use database/sql.Conn.Raw (Go >= 1.13):
conn, err := db.Conn(context.Background())
// if err != nil { ... }
defer conn.Close()
err = conn.Raw(func (driverConn any) error {
sqliteConn := driverConn.(*sqlite3.SQLiteConn)
// ... use sqliteConn
})
// if err != nil { ... }
# Go SQlite3 Extensions
If you want to register Go functions as SQLite extension functions
you can make a custom driver by calling RegisterFunction from
ConnectHook.
regex = func(re, s string) (bool, error) {
return regexp.MatchString(re, s)
}
sql.Register("sqlite3_extended",
&sqlite3.SQLiteDriver{
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
return conn.RegisterFunc("regexp", regex, true)
},
})
You can then use the custom driver by passing its name to sql.Open.
var i int
conn, err := sql.Open("sqlite3_extended", "./foo.db")
if err != nil {
panic(err)
}
err = db.QueryRow(`SELECT regexp("foo.*", "seafood")`).Scan(&i)
if err != nil {
panic(err)
}
See the documentation of RegisterFunc for more details.

// This file provides several different implementations for the
// default embedded sqlite_crypt function.
// This function is uses a caesar-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 Caesar-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.

/*
Package strftime provides strftime/strptime compatible time formatting and parsing.
The following specifiers are available:
Date (Year, Month, Day):
%Y - Year with century (can be negative, 4 digits at least)
-0001, 0000, 1995, 2009, 14292, etc.
%C - year / 100 (round down, 20 in 2009)
%y - year % 100 (00..99)
%m - Month of the year, zero-padded (01..12)

This library is a toy proof-of-concept implementation of the
well-known Schonhage-Strassen method for multiplying integers.
It is not expected to have a real life usecase outside number
theory computations, nor is it expected to be used in any production
system.
If you are using it in your project, you may want to carefully
examine the actual requirement or problem you are trying to solve.

Portions of this software are derived from third-party works licensed
under terms compatible with the above MIT license:
The TRE regular expression implementation (src/regex/reg* and
src/regex/tre*) is Copyright © 2001-2008 Ville Laurikari and licensed
under a 2-clause BSD license (license text in the source files). The
included version has been heavily modified by Rich Felker in 2012, in
the interests of size, simplicity, and namespace cleanliness.
Much of the math library code (src/math/* and src/complex/*) is
Copyright © 1993,2004 Sun Microsystems or
Copyright © 2003-2011 David Schultz or
Copyright © 2003-2009 Steven G. Kargl or
Copyright © 2003-2009 Bruce D. Evans or
Copyright © 2008 Stephen L. Moshier or
Copyright © 2017-2018 Arm Limited
and labelled as such in comments in the individual source files. All
have been licensed under extremely permissive terms.
The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
The Android Open Source Project and is licensed under a two-clause BSD
license. It was taken from Bionic libc, used on Android.
The AArch64 memcpy and memset code (src/string/aarch64/*) are
Copyright © 1999-2019, Arm Limited.
The implementation of DES for crypt (src/crypt/crypt_des.c) is
Copyright © 1994 David Burren. It is licensed under a BSD license.
The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
originally written by Solar Designer and placed into the public
domain. The code also comes with a fallback permissive license for use
in jurisdictions that may not recognize the public domain.
The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
Valentin Ochs and is licensed under an MIT-style license.
The x86_64 port was written by Nicholas J. Kain and is licensed under
the standard MIT terms.
The mips and microblaze ports were originally written by Richard
Pennington for use in the ellcc project. The original code was adapted
by Rich Felker for build system and code conventions during upstream
integration. It is licensed under the standard MIT terms.
The mips64 port was contributed by Imagination Technologies and is
licensed under the standard MIT terms.
The powerpc port was also originally written by Richard Pennington,
and later supplemented and integrated by John Spencer. It is licensed
under the standard MIT terms.
All other files which have no copyright comments are original works
produced specifically for use as part of this library, written either
by Rich Felker, the main author of the library, or by one or more
contibutors listed above. Details on authorship of individual files
can be found in the git version control history of the project. The
omission of copyright and license comments in each file is in the
interest of source tree size.
In addition, permission is hereby granted for all public header files
(include/* and arch/*/bits/*) and crt files intended to be linked into
applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit
the copyright notice and permission notice otherwise required by the
license, and to use these files without any requirement of
attribution. These files include substantial contributions from:
Bobby Bingham
John Spencer
Nicholas J. Kain
Rich Felker
Richard Pennington
Stefan Kristiansson
Szabolcs Nagy
all of whom have explicitly granted such permission.
This file previously contained text expressing a belief that most of
the files covered by the above exception were sufficiently trivial not
to be subject to copyright, resulting in confusion over whether it
negated the permissions granted in the license. In the spirit of
permissive licensing, and of not having licensing issues being an
obstacle to adoption, that text has been removed.
