Vendor the spellfix1 extension source and compile it directly into the binary via cgo, avoiding runtime shared library dependencies across platforms. The extension is registered via sqlite3_auto_extension so every new SQLite connection has spellfix1 available. Signed-off-by: Deluan <deluan@navidrome.org>

# spellfix1 SQLite Extension
|
|
|
|
This package statically compiles the [spellfix1](https://sqlite.org/spellfix1.html) SQLite extension
|
|
into the Navidrome binary. It is registered via `sqlite3_auto_extension` so that every new SQLite
|
|
connection has `spellfix1` available without loading a shared library.
|
|
|
|
## Vendored Files
|
|
|
|
The C source files are vendored because cgo cannot reference headers from other Go modules:
|
|
|
|
- **`spellfix.c`** — from the SQLite source tree: [`ext/misc/spellfix.c`](https://github.com/sqlite/sqlite/blob/master/ext/misc/spellfix.c)
|
|
- **`sqlite3ext.h`** — from the SQLite source tree: [`src/sqlite3ext.h`](https://github.com/sqlite/sqlite/blob/master/src/sqlite3ext.h)
|
|
|
|
## Updating
|
|
|
|
When upgrading `github.com/mattn/go-sqlite3`, run the update script to download
|
|
the matching spellfix1 source files for the bundled SQLite version:
|
|
|
|
```bash
|
|
./db/spellfix/update.sh
|
|
```
|
|
|
|
The script reads the SQLite version from go-sqlite3's `sqlite3-binding.h` and
|
|
downloads the corresponding files from the [SQLite GitHub mirror](https://github.com/sqlite/sqlite).
