Issue Overview: SQLite Unix VFS Path Length Limitation The core issue revolves around the SQLite Unix VFS (Virtual File System) imposing a hard-coded limit on the length of database file paths. Specifically, the MAX_PATHNAME constant in the SQLite source code is set to 512 characters, which includes the null-terminator. This means that any database file…
The Role of idxStr in SQLite Virtual Tables The idxStr parameter in SQLite virtual tables is a critical component of the xBestIndex and xFilter methods, which are part of the virtual table interface. The xBestIndex method is responsible for determining the best way to access the virtual table based on the query constraints, while the…
Enabling Compression for SQLite WASM in Apache The core issue revolves around optimizing the delivery of SQLite WebAssembly (WASM) binaries through an Apache web server. WASM binaries, while highly efficient in execution, can be relatively large in size, which impacts load times and performance, especially in web environments. The discussion highlights two key aspects: enabling…
