Paul Fitzpatrick	45d2d5f897	(core) back-end support for tables that are accessible only by owners ... Summary: This makes it possible to serve a table or tables only to owners. * The _grist_ACLResources table is abused (temporarily) such that rows of the form `{colId: '~o', tableId}` are interpreted as meaning that `tableId` is private to owners. * Many websocket and api endpoints are updated to preserve the privacy of these tables. * In a document where some tables are private, a lot of capabilities are turned off for non-owners to avoid leaking info indirectly. * The client is tweaked minimally, to show '-' where a page with some private material would otherwise go. No attempt is made to protect data from private tables pulled into non-private tables via formulas. There are some known leaks remaining: * Changes to the schema of private tables are still broadcast to all clients (fixable). * Non-owner may be able to access snapshots or make forks or use other corners of API (fixable). * Changing name of table makes it public, since tableId in ACLResource is not updated (fixable). Security will require some work, the attack surface is large. Test Plan: added tests Reviewers: dsagal Reviewed By: dsagal Differential Revision: https://phab.getgrist.com/D2604	4 years ago
Paul Fitzpatrick	4a545c9f2a	(core) make sharing with everyone@ on documents effective ... Summary: Sharing a document with everyone@ was effective at the api level, but had two flaws in the web client: * A logged in user with no access at the org level could not access a publically shared doc within that org. * Likewise, for the anonymous user (but for a different reason). This diff tweaks the web client to permit accessing a doc when org information is unavailable. It also changes how redirects happen for the anonymous user when accessing a doc. They now only happen once it has been confirmed that the user does not have access to the doc.

Paul Fitzpatrick	5ef889addd	(core) move home server into core ... Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
