The following configurations are tested in CI.

The following configurations are not tested but are expected to work.

You need a working Go toolchain.

These customize the Go SQLite VFS.

Use vfs.SupportsFileLocking to check if your build supports file locking:

• 🟢 full support
• 🟡 reduced concurrency: BEGIN IMMEDIATE behaves like BEGIN EXCLUSIVE (docs)
• 🟠 incompatible locking: accessing databases concurrently with other SQLite libraries risks data corruption
• 🔴 no support: can only open databases with nolock=1 (or immutable=1); WAL mode not supported

Use vfs.SupportsSharedMemory to check if your build supports shared memory:

• 🟢 full support
• 🟡 reduced performance: memory sharing through copying, which reduces performance under write-heavy workloads
• 🟠 in-process: WAL databases can only be accessed by a single proccess; other processes fail with SQLITE_PROTOCOL, SQLITE_IOERR, or SQLITE_CANTOPEN
• 🔴 no support: can only open WAL databases with EXCLUSIVE locking mode
