1426379903,PR_kwDOBm6k_c5BtJNn,1870,"don't use immutable=1, only mode=ro",536941,open,0,,,7,2022-10-27T23:33:04Z,2023-10-03T19:12:37Z,,CONTRIBUTOR,simonw/datasette/pulls/1870,"Opening db files in immutable mode sometimes leads to the file being mutated, which causes duplication in the docker image layers: see #1836, #1480

That this happens in ""immutable"" mode is surprising, because the sqlite docs say that setting this should open the database as read only. 

https://www.sqlite.org/c3ref/open.html

> immutable: The immutable parameter is a boolean query parameter that indicates that the database file is stored on read-only media. When immutable is set, SQLite assumes that the database file cannot be changed, even by a process with higher privilege, and so the database is opened read-only and all locking and change detection is disabled. Caution: Setting the immutable property on a database file that does in fact change can result in incorrect query results and/or [SQLITE_CORRUPT](https://www.sqlite.org/rescode.html#corrupt) errors. See also: [SQLITE_IOCAP_IMMUTABLE](https://www.sqlite.org/c3ref/c_iocap_atomic.html).

Perhaps this is a bug in sqlite?

in particular, 

1. in a table view, there is not a link from the row to the referenced row if the foreign key is compound
2. in a row view, there is no listing of tables and rows that refer to the focal row if those referencing foreign keys are compound.

Both of these issues are discussed in #1099. 

This PR only fixes the second one, because it's not clear what the right UX is for the first issue.

Some things that might not be desirable about this approach.

1. it changes the external API, by changing `column` => `columns` and `other_column` => `other_columns` (see inline comment for more discussion.
2. There are various places where the plural foreign keys have to be checked for length and discarded or transformed to singular.

If it was possible for datasette to handle extra options, like [standard Django does](https://docs.djangoproject.com/en/3.2/topics/http/urls/#passing-extra-options-to-view-functions), it would add flexibility for plugin authors.

For example, if extra options were enabled, then it would be easy to make a single table the home page (#1284). This plugin would accomplish it.

```python
from datasette import hookimpl
from datasette.views.table import TableView

@hookimpl
def register_routes(datasette):
        return [
        (r""^/$"", TableView.as_view(datasette), {'db_name': 'DB_NAME',
