PR Summary

Implement Factory Pattern for SQLite Database Access with Encryption Support

Overview

This PR refactors the database access layer to use a factory pattern, enabling support for both encrypted and unencrypted SQLite databases. The implementation adds new factory classes and modifies existing components to work with this abstraction.

Change Types

Type	Description
Feature	Added support for encrypted SQLite databases
Refactor	Implemented factory pattern for database access
Enhancement	Modified existing components to work with the new abstraction

Notes for Reviewers

• The factory pattern implementation allows for runtime selection between encrypted and unencrypted database access
• Verify that both encrypted and unencrypted database operations work correctly
• Check that the RequestHandler properly uses the injected factory

🐛 Correctness Issue

Breaking API Change: Constructor Parameter Added.

The RequestHandler constructor now requires a DBFactory parameter, which will break all existing code that instantiates this class.

Current Code (Diff):

- public RequestHandler(Context context) {
+ public RequestHandler(Context context, DBFactory dbFactory) {

🔒 Security Issue

Security: Ignored Password Parameter.

The password parameter is accepted but ignored when opening the database, which could lead to unencrypted database access in production if encryption is expected.

Current Code (Diff):

-         return new DebugSQLiteDB(SQLiteDatabase.openOrCreateDatabase(path, null));
+         return new DebugSQLiteDB(SQLiteDatabase.openOrCreateDatabase(path, password, null));

Suggested change

	return new DebugSQLiteDB(SQLiteDatabase.openOrCreateDatabase(path, null));
	return new DebugSQLiteDB(SQLiteDatabase.openOrCreateDatabase(path, password, null));

🐛 Correctness Issue

Correctness: No Error Handling.

SQLiteDatabase.openOrCreateDatabase can throw exceptions for invalid paths or permission issues with no error handling, causing application crashes.

Current Code (Diff):

-     public SQLiteDB create(Context context, String path, String password) {
-         return new DebugSQLiteDB(SQLiteDatabase.openOrCreateDatabase(path, null));
-     }
+     public SQLiteDB create(Context context, String path, String password) {
+         try {
+             return new DebugSQLiteDB(SQLiteDatabase.openOrCreateDatabase(path, password, null));
+         } catch (Exception e) {
+             throw new RuntimeException("Failed to open database at " + path, e);
+         }
+     }

🔒 Security Issue

Security: Database Encryption Removed.

Switching from SQLCipher to standard SQLite removes encryption, potentially exposing sensitive data if this debug implementation is used with real user data.

Current Code (Diff):

- import android.database.sqlite.SQLiteDatabase;

+ import net.sqlcipher.database.SQLiteDatabase;
+ 
+ /**
+  * Created by anandgaurav on 12/02/18.
+  */

🔄 Dependencies Affected

debug-db/src/main/java/com/amitshekhar/debug/sqlite/DebugDBFactory.java

Function: DebugDBFactory.openOrCreateDatabase

Issue: Database factory creates unencrypted database instances

Suggestion: Either ensure this implementation is only used for debugging or restore encryption capability
