Issue Overview: Compatibility of WAL-Enabled Databases with SQLite WASM Builds SQLite’s Write-Ahead Logging (WAL) mode offers performance benefits for concurrent read/write operations in native environments. However, when working with SQLite’s WebAssembly (WASM) builds, particularly in browser-based applications, attempts to open WAL-enabled databases often fail with errors such as SQLite3Error: sqlite3 result code 26: file is…

Core Requirements for Enabling OPFS VFS in SQLite WASM Environments Understanding OPFS Availability Failures in Browser-Based SQLite The inability to access Origin-Private File System (OPFS) APIs via SQLite’s WebAssembly (WASM) build manifests as skipped test groups when running browser-based test suites like test1-worker.html. This occurs when the JavaScript environment fails to meet three critical prerequisites…

Issue Overview: IOERR During SQLite Porting to RTOS Due to Zero-Sized File When porting SQLite to a new operating system, particularly a Real-Time Operating System (RTOS), one of the most common issues that developers encounter is the SQLITE_IOERR (I/O Error). This error often manifests when SQLite attempts to interact with the file system, especially during…

Issue Overview: Duplicate pgoffset Values in dbstat Output The core issue revolves around the observation that the dbstat virtual table in SQLite is producing duplicate pgoffset values for different types of pages within the same database file. Specifically, leaf pages and overflow pages are being assigned the same pgoffset values, which is unexpected and potentially…

Understanding SQLite Database Connections and Their Implications SQLite database connections are fundamental to interacting with the database, and understanding how they work is crucial for optimizing performance, avoiding deadlocks, and managing schema changes. A database connection in SQLite is represented by a pointer to a sqlite3 object, which serves as the gateway for executing SQL…

Issue Overview: Compatibility Conflicts Between Node.js Versions and SQLite3 NPM Package Releases The error message "Cannot find module sqlite3" in Node.js environments often stems from incompatibility between the installed version of the SQLite3 NPM package and the Node.js runtime. This issue is particularly prevalent when attempting to use newer versions of the SQLite3 NPM package…

Issue Overview: Lack of Official RSS Feed for SQLite News Updates The core issue revolves around the absence of an official RSS (Really Simple Syndication) feed for SQLite’s news and release updates. RSS feeds are a standardized way to distribute frequently updated content, such as news articles, blog posts, or software release notes, in a…

Understanding SQLAR Compilation and Database Location Configuration When working with SQLAR (SQLite Archive), a common challenge arises during the compilation of its source code on Windows using the CL (Microsoft C/C++ Compiler). Additionally, users often struggle to determine how SQLAR identifies the name and location of the SQLite database that contains the sqlar table. This…

Issue Overview: SQLITE_BUSY and SQLITE_LOCKED Error Code Differentiation The error message "database is locked" accompanied by the code = Busy (5) in System.Data.SQLite.SQLiteException indicates a SQLITE_BUSY condition, not SQLITE_LOCKED. While both errors relate to database or table locking conflicts, their root causes, implications, and resolutions differ significantly. SQLITE_BUSY (error code 5) occurs when a database…

Issue Overview: Compilation Hangs When Using g++ for SQLite3 in C++ When integrating SQLite3 into a C++ project, particularly in an Android development environment using Anacode IDE, developers often encounter a scenario where the compilation process hangs indefinitely. This issue is primarily observed when attempting to compile SQLite3’s C source code (sqlite3.c) using the g++…
