(core) support adding user characteristic tables for granular ACLs Summary: This is a prototype for expanding the conditions that can be used in granular ACLs. When processing ACLs, the following variables (called "characteristics") are now available in conditions: * UserID * Email * Name * Access (owners, editors, viewers) The set of variables can be expanded by adding a "characteristic" clause. This is a clause which specifies: * A tableId * The name of an existing characteristic * A colId The effect of the clause is to expand the available characteristics with all the columns in the table, with values taken from the record where there is a match between the specified characteristic and the specified column. Existing clauses are generalized somewhat to demonstrate and test the use these variables. That isn't the main point of this diff though, and I propose to leave generalizing+systematizing those clauses for a future diff. Issues I'm not dealing with here: * How clauses combine. (The scope on GranularAccessRowClause is a hack to save me worrying about that yet). * The full set of matching methods we'll allow. * Refreshing row access in clients when the tables mentioned in characteristic tables change. * Full CRUD permission control. * Default rules (part of combination). * Reporting errors in access rules. That said, with this diff it is possible to e.g. assign a City to editors by their email address or name, and have only rows for those Cities be visible in their client. Ability to modify those rows, and remain updates about them, remains under incomplete control.

(core) add initial support for special shares Summary: This gives a mechanism for controlling access control within a document that is distinct from (though implemented with the same machinery as) granular access rules. It was hard to find a good way to insert this that didn't dissolve in a soup of complications, so here's what I went with: * When reading rules, if there are shares, extra rules are added. * If there are shares, all rules are made conditional on a "ShareRef" user property. * "ShareRef" is null when a doc is accessed in normal way, and the row id of a share when accessed via a share. There's no UI for controlling shares (George is working on it for forms), but you can do it by editing a `_grist_Shares` table in a document. Suppose you make a fresh document with a single page/table/widget, then to create an empty share you can do: ``` gristDocPageModel.gristDoc.get().docData.sendAction(['AddRecord', '_grist_Shares', null, {linkId: 'xyz', options: '{"publish": true}'}]) ``` If you look at the home db now there should be something in the `shares` table: ``` $ sqlite3 -table landing.db "select * from shares" +----+------------------------+------------------------+--------------+---------+ | id | key | doc_id | link_id | options | +----+------------------------+------------------------+--------------+---------+ | 1 | gSL4g38PsyautLHnjmXh2K | 4qYuace1xP2CTcPunFdtan | xyz | ... | +----+------------------------+------------------------+--------------+---------+ ``` If you take the key from that (gSL4g38PsyautLHnjmXh2K in this case) and replace the document's urlId in its URL with `s.<key>` (in this case `s.gSL4g38PsyautLHnjmXh2K` then you can use the regular document landing page (it will be quite blank initially) or API endpoint via the share. E.g. for me `http://localhost:8080/o/docs/s0gSL4g38PsyautLHnjmXh2K/share-inter-3` accesses the doc. To actually share some material - useful commands: ``` gristDocPageModel.gristDoc.get().docData.getMetaTable('_grist_Views_section').getRecords() gristDocPageModel.gristDoc.get().docData.sendAction(['UpdateRecord', '_grist_Views_section', 1, {shareOptions: '{"publish": true, "form": true}'}]) gristDocPageModel.gristDoc.get().docData.getMetaTable('_grist_Pages').getRecords() gristDocPageModel.gristDoc.get().docData.sendAction(['UpdateRecord', '_grist_Pages', 1, {shareRef: 1}]) ``` For a share to be effective, at least one page needs to have its shareRef set to the rowId of the share, and at least one widget on one of those pages needs to have its shareOptions set to {"publish": "true", "form": "true"} (meaning turn on sharing, and include form sharing), and the share itself needs {"publish": true} on its options. I think special shares are kind of incompatible with public sharing, since by their nature (allowing access to all endpoints) they easily expose the docId, and changing that would be hard.
