For example, the upcoming version of `sqlite-lines` will have 2 entrypoints: the default `sqlite3_lines_init` (which SQLite will automatically guess for) and `sqlite3_lines_noread_init`. The `sqlite3_lines_noread_init` version omits functions that read from the filesystem, which is necessary for security purposes when running untrusted SQL (which Datasette does). (Similar multiple entrypoints will also be added for sqlite-http). The `--load-extension` flag, however, doesn't give the option to specify a different entrypoint, so the default one is always used. ## Proposal I want there to be a new command line option of the `--load-extension` flag to specify a custom entrypoint like so: ``` datasette my.db \ --load-extension ./lines0 sqlite3_lines0_noread_init ``` Then, under the hood, this line of code: https://github.com/simonw/datasette/blob/7af67b54b7d9bca43e948510fc62f6db2b748fa8/datasette/app.py#L562 Would look something like this: ```python conn.execute("SELECT load_extension(?, ?)", [extension, entrypoint]) ``` One potential problem: For backward compatibility, I'm not sure if Click allows cli flags to have variable number of options ("arity"). So I guess it could also use a `:` delimiter like `--static`: ``` datasette my.db \ --load-extension ./lines0:sqlite3_lines0_noread_init ``` Or maybe even a new flag name? ``` datasette my.db \ --load-extension-entrypoint ./lines0 sqlite3_lines0_noread_init ``` Personally I prefer the `:` option... and maybe even `--load-extension` -> `--load`? Definitely out of scope for this issue tho ``` datasette my.db \ --load./lines0:sqlite3_lines0_noread_init ``` | 107914493 | issue | {"url": "https://api.github.com/repos/simonw/datasette/issues/1784/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | completed |
