Memory Database Persistence and SQLITE_MISUSE Error on Connection Closure The core issue revolves around an in-memory SQLite database that persists even after calling sqlite3_close_v2(), accompanied by an SQLITE_MISUSE error (error code 21). This error indicates that the database connection pointer passed to sqlite3_close_v2() is invalid, likely because the connection was already closed or because there…

Understanding SQLite’s Architecture and Shared Database Access Limitations SQLite is fundamentally designed as an embedded database engine, not a client-server database system. Its architecture revolves around direct file access, with each database residing in a single file on disk or entirely in memory. The core library interacts with the database file through standard file I/O…

Issue Overview: Compilation Errors When Building SQLite for Universal macOS Binaries When attempting to compile SQLite as a universal binary for macOS (supporting both Intel x86_64 and Apple Silicon arm64 architectures), developers often encounter a series of compilation errors and warnings. These issues arise due to a combination of incorrect compiler usage, misunderstandings about the…

Geopoly Virtual Table and NATURAL JOIN Interaction Leading to Assertion Failure in Debug Builds Issue Overview: Assertion Failure in sqlite3ColumnExpr During Geopoly Virtual Table NATURAL JOIN Query Execution The core issue revolves around an assertion failure triggered within the SQLite library when executing a specific query involving a Geopoly virtual table and a NATURAL JOIN…

Dependency Configuration Failure During Asterisk Installation The core issue revolves around a failed installation of the libsqlite3-dev package, which is required for compiling Asterisk, a telephony framework. The failure manifests in two stages: Asterisk’s configure script detects the absence of SQLite3 development headers, critical for linking the Asterisk database module. Attempting to install libsqlite3-dev via…

Issue Overview: Diagnosing Disk-Related Commit Errors in SQLite When SQLite encounters a failure during a transaction commit operation, developers often rely on its error codes to determine the root cause. A common scenario involves commit failures due to insufficient disk space. However, SQLite does not inherently monitor disk space availability. Instead, it propagates errors generated…

Issue Overview: ‘NEW’ and ‘OLD’ in Triggers vs. Keyword List Absence The core issue revolves around the absence of ‘NEW’ and ‘OLD’ from SQLite’s official keyword list despite their prominent use in trigger definitions. Users familiar with SQL syntax often expect such identifiers to be reserved keywords, but SQLite treats them contextually. This discrepancy arises…

Issue Overview: OPFS VFS Not Found in C++ WebAssembly SQLite Integration The core challenge revolves around attempting to use SQLite’s Origin Private File System (OPFS) Virtual File System (VFS) from a C++ library compiled to WebAssembly (Wasm). The developer observes that sqlite3_vfs_find("opfs") returns a null pointer, indicating the VFS is unavailable. This occurs because the…

Issue Overview: Parsing SQLite CLI Output for Remote Database Connections The core issue revolves around the challenges of parsing SQLite CLI output when building a library to connect to a remote SQLite database over SSH. The goal is to enable GUI database management tools to interact with SQLite databases remotely by leveraging the server-side sqlite3…

Issue Overview: Missing Closing Brace in Nested Case Statements The issue at hand revolves around a seemingly missing closing brace in a switch/case block within the vdbe.c file of SQLite’s source code. Specifically, the case OP_ReopenIdx block appears to lack a closing brace before the subsequent case OP_OpenRead and case OP_OpenWrite statements. This observation initially…
