# Simplified SQLite3 Wrapper with Multi-Thread Safety

SQLite4 provides a simplified wrapper for SQLite3, along with built-in multi-thread safety.

## Installation

You can easily install SQLite4 using `pip3`:
````bash
pip3 install sqlite4
````
## Usage

````python
from  sqlite4  import  SQLite4

# Init database object, singleton pattern restricts multiple objects per db
database = SQLite4("database.db")
# Connect to db and creates execution thread
database.connect()
# Create test database and specify columns
database.create_table("test", ["foo", "bar"])
# insert
database.insert("test", {"foo": "foo", "bar": "bar"})
# update
database.update("test", {"foo": "fooo", "bar": "baar"}, "1 = 1")
# delete
database.delete("test", "1 == 1")
# select all
database.select("test")
# conditional select
database.select("test", columns=['foo'], condition='foo = "fooo"')
# custom query
database.execute(...)
````

## Multithreaded usage

````python
from  sqlite4.SQLite4  import  SQLite4
import  uuid
import  concurrent.futures

with  concurrent.futures.ThreadPoolExecutor(max_workers=50) as  executor:
	# This example shows how easy sqlite4 handles multithread access under the hood
	db = SQLite4("database.db")
	db.connect()
	db.create_table("test", ["foo", "bar"])
		def  insert():
			db.insert("test", {"foo": str(uuid.uuid4()), "bar": str(uuid.uuid4())})
	futures  = [executor.submit(insert) for  _  in  range(50)]
	concurrent.futures.wait(futures)
````

## How does it work ?

#### Singleton Pattern
The Singleton pattern restricts the instantiation of a class to just one object. When you create an instance of the SQLite4 class, it checks if an instance already exists for the specified database. If one does, it returns the existing instance; otherwise, it creates a new instance for the specified database. This design pattern is particularly useful for managing database connections, as it provides a centralized point of access.
#### Thread Safety with Execution Pipe
To ensure multi-thread safety and prevent potential deadlocks, SQLite4 utilizes an execution pipe. Whenever CRUD methods (Create, Read, Update, Delete) or custom SQL queries are called, the execution requests are sent to this pipe instead of directly accessing the database.
1.  When a CRUD method or custom SQL query is invoked, SQLite4 places the request in a queue that serves as the execution pipe.
2.  In a separate execution thread, the requests are processed one by one from the execution pipe.
3.  The separate thread reads the requests and executes them sequentially on the SQLite database.
