9628253fd8 (core) Adding new column in users table "ref" with unique identifier.
Summary:
There is a new column in users table called ref (user reference).
It holds user's unique reference number that can be used for features
that require some kind of ownership logic (like comments).

dd8d2e18f5 (core) add an access token mechanism to help with attachments in custom widgets
Summary:
With this, a custom widget can render an attachment by doing:
```
const tokenInfo = await grist.docApi.getAccessToken({readOnly: true});
const img = document.getElementById('the_image');
const id = record.C[0];  // get an id of an attachment
const src = `${tokenInfo.baseUrl}/attachments/${id}/download?auth=${tokenInfo.token}`;
img.setAttribute('src', src)
```

The access token expires after a few mins, so if a user right-clicks on an image
to save it, they may get access denied unless they refresh the page. A little awkward,
but s3 pre-authorized links behave similarly and it generally isn't a deal-breaker.

ec8ab598cb (core) add a yarn run cli tool, and add a sqlite gristify option
Summary:
This adds rudimentary support for opening certain SQLite files in Grist.

If you have a file such as `landing.db` in Grist, you can convert it to Grist format by doing (either in monorepo or grist-core):
```
yarn run cli -h
yarn run cli sqlite -h
yarn run cli sqlite gristify landing.db
```

The file is now openable by Grist. To actually do so with the regular Grist server, you'll need to either import it, or convert some doc you don't care about in the `samples/` directory to be a soft link to it (and then force a reload).

This implementation is a rudimentary experiment. Here are some awkwardnesses:
 * Only tables that happen to have a column called `id`, and where the column happens to be an integer, can be opened directly with Grist as it is today. That could be generalized, but it looked more than a Gristathon's worth of work, so I instead used SQLite views.
 * Grist will handle tables that start with an uncapitalized letter a bit erratically. You can successfully add columns, for example, but removing them will cause sadness - Grist will rename the table in a confused way.
 * I didn't attempt to deal with column names with spaces etc (though views could deal with those).
 * I haven't tried to do any fancy type mapping.
 * Columns with constraints can make adding new rows impossible in Grist, since Grist requires that a row can be added with just a single cell set.

51ff72c15e (core) Faster builds all around.
Summary:
Building:
- Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast.
- Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var.
- Grist-core continues to build using tsc.
- Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned
  on, so that tsc accepts and enforces correct usage.
- Client-side code is watched and bundled by webpack as before (using esbuild-loader)

Code changes:
- Imports must now follow ES6 semantics: `import * as X from ...` produces a
  module object; to import functions or class instances, use `import X from ...`.
- Everything is now built with isolatedModules flag. Some exports were updated for it.

Packages:
- Upgraded browserify dependency, and related packages (used for the distribution-building step).
- Building the distribution now uses esbuild's minification. babel-minify is no longer used.

Test Plan: Should have no behavior changes, existing tests should pass, and docker image should build too.

cf23a2d1ee (core) add GVISOR_LIMIT_MEMORY to cap memory available in sandbox
Summary:
This allows limiting the memory available to documents in the sandbox when gvisor is used. If memory limit is exceeded, we offer to open doc in recovery mode. Recovery mode is tweaked to open docs with tables in "ondemand" mode, which will generally take less memory and allow for deleting rows.

The limit is on the size of the virtual address space available to the sandbox (`RLIMIT_AS`), which in practice appears to function as one would want, and is the only practical option. There is a documented `RLIMIT_RSS` limit to `specifies the limit (in bytes) of the process's resident set (the number of virtual pages resident in RAM)` but this is no longer enforced by the kernel (neither the host nor gvisor).

When the sandbox runs out of memory, there are many ways it can fail. This diff catches all the ones I saw, but there could be more.

59436d2bca (core) Grace period and delete-only mode when exceeding row limit
Summary:
Builds upon https://phab.getgrist.com/D3328

- Add HomeDB column `Document.gracePeriodStart`
- When the row count moves above the limit, set it to the current date. When it moves below, set it to null.
- Add DataLimitStatus type indicating if the document is approaching the limit, is in a grace period, or is in delete only mode if the grace period started at least 14 days ago. Compute it in ActiveDoc and send it to client when opening.
- Only allow certain user actions when in delete-only mode.

Follow-up tasks related to this diff:

- When DataLimitStatus in the client is non-empty, show a banner to the appropriate users.
- Only send DataLimitStatus to users with the appropriate access. There's no risk landing this now since real users will only see null until free team sites are released.
- Update DataLimitStatus immediately in the client when it changes, e.g. when user actions are applied or the product is changed. Right now it's only sent when the document loads.
- Update row limit, grace period start, and data limit status in ActiveDoc when the product changes, i.e. the user upgrades/downgrades.
- Account for data size when computing data limit status, not just row counts.

546096fcc9 (core) Clean up and refactor uses of HomeDBManager.getDoc
Summary:
Firstly I just wanted some more consistency and less repetition in places where Documents are retrieved from the DB, so it's more obvious when code differs from the norm. Main changes for that part:

- Let HomeDBManager accept a `Request` directly and convert it to a `Scope`, and use this in a few places.
- `getScope` tries `req.docAuth.docId` if `req.params` doesn't have a docId.

I also refactored how `_createActiveDoc` gets the document URL, separating out getting the document from getting a URL for it. This is because I want to use that document object in a future diff, but I also just find it cleaner. Notable changes for that:

- Extracted a new method `HomeDBManager.getRawDocById` as an alternative to `getDoc` that's explicitly for when you only have a document ID.
- Removed the interface method `GristServer.getDocUrl` and its two implementations because it wasn't used elsewhere and it didn't really add anything on top of getting a doc (now done by `getRawDocById`) and `getResourceUrl`.
- Between `cachedDoc` and `getRawDocById` (which represent previously existing code paths) also try `getDoc(getScope(docSession.req))`, which is new, because it seems better to only `getRawDocById` as a last resort.

Summary:
Add rowCount returned from sandbox when applying user actions to ActionGroup which is broadcast to clients.

Add rowCount to ActiveDoc and update it after applying user actions.

Add rowCount to OpenLocalDocResult using ActiveDoc value, to show when a client opens a doc before any user actions happen.

Add rowCount observable to DocPageModel which is set when the doc is opened and when action groups are received.

Add crude UI (commented out) in Tool.ts showing the row count and the limit in AppModel.currentFeatures. The actual UI doesn't have a place to go yet.

Followup tasks:

- Real, pretty UI
- Counts per table
- Keep count(s) secret from users with limited access?
- Data size indicator?
- Banner when close to or above limit
- Measure row counts outside of sandbox to avoid spoofing with formula
- Handle changes to the limit when the plan is changed or extra rows are purchased

Test Plan: Tested UI manually, including with free team site, opening a fresh doc, opening an initialised doc, adding rows, undoing, and changes from another tab. Automated tests seem like they should wait for a proper UI.

c4d3d7d3bb (core) be careful when reassigning a doc to a worker it was on before
Summary:
Importing a .grist document is implemented in a somewhat clunky way, in a multi-worker setup.

 * First a random worker receives the upload, and updates Grist's various stores appropriately (database, redis, s3).
 * Then a random worker is assigned to serve the document.

If the worker serving the document fails, there is a chance the it will end up assigned to the worker that handled its upload. Currently the worker will misbehave in this case. This diff:

 * Ports a multi-worker test from test/home to run in test/s3, and adds a test simulating a bad scenario seen in the wild.
 * Fixes persistence of any existing document checksum in redis when a worker is assigned.
 * Adds a check when assigned a document to serve, and finding that document already cached locally. It isn't safe to rely only on the document checksum in redis, since that may have expired.
 * Explicitly claims the document on the uploading worker, so this situation becomes even less likely to arise.

b3b7410ede (core) open documents without blocking on data engine
Summary:
With this diff, when a user opens a Grist document in a browser, they will be able to view its contents without waiting for the data engine to start up. Once the data engine starts, it will run a calculation and send any updates made. Changes to the document will be blocked until the engine is started and the initial calculation is complete.

The increase in responsiveness is useful in its own right, and also reduces the impact of an extra startup time in a candidate next-generation sandbox.

A small unrelated fix is included for `core/package.json`, to catch up with a recent change to `package.json`.

A small `./build schema` convenience is added to just rebuild the typescript schema file.

876a0298a2 (core) do not look at content of recent actions when loading documents
Summary:
This removes the need for any information drawn from the content of recent actions when loading a document.

The undo/redo system does need some facts about recent actions up front. But that system has an important restriction: only actions a particular client is known to have generated can be undone by that client.

So in this diff, as we store which client has performed an action, we also store the few pieces of metadata about that action that the undo/redo system needs: `linkId`, `otherId`, `rowIdHint`, `isUndo` fields. These are all small integers (or in one case a boolean).

An existing limitation is that information about which client has performed which action is stored in memory in the worker, and not persisted anywhere. This diff does not change that limitation, meaning that undos continue to not survive a worker transition. A reasonable way to deal with that would be to back the store with redis.

95cc2eb282 (core) read document as owner in pre-fork mode, if have sufficient access to it
Summary:
This tweaks pre-fork mode to make the user's experience a bit more seamless.
Pre-fork mode is where the user has opened a document with intent to
fork it, but actual forking (with allocation of a new document id)
is postponed until they make their first change.

The tweak makes the user an owner for granular access purposes, if
forking is permitted.  So data visible only to owners because of
access rules will be visible to them.  As always, any edits would
go to a separate new copy.

A remaining tricky corner is what to do about "View As" functionality
on forks.  Fork sharing cannot be controlled, so the "Users -> View As"
functionality isn't available.  Perhaps the "Users" button on a fork
could encourage doing a save-copy and inviting users, or offer some
dummy users?  In any case, this diff doesn't change anything with
that corner.

Summary:
This applies some mitigations suggested by SQLite authors when

  https://www.sqlite.org/security.html#untrusted_sqlite_database_files

Steps implemented in this diff are:

  * Running a SQLite-level integrity check on uploads

Other steps will require updates to our node-sqlite3 fork, since they
are not available via the node-sqlite3 api (one more reason to migrate
to better-sqlite3).

check failure without also being detected as corruption by sqlite

0c5f7cf0a7 (core) add SELF_HYPERLINK() function for generating links to the current document
Summary:
 * Adds a `SELF_HYPERLINK()` python function, with optional keyword arguments to set a label, the page, and link parameters.
 * Adds a `UUID()` python function, since using python's uuid.uuidv4 hits a problem accessing /dev/urandom in the sandbox.  UUID makes no particular quality claims since it doesn't use an audited implementation.  A difficult to guess code is convenient for some use cases that `SELF_HYPERLINK()` enables.

The canonical URL for a document is mutable, but older versions generally forward.  So for implementation simplicity the document url is passed it on sandbox creation and remains fixed throughout the lifetime of the sandbox.  This could and should be improved in future.

The URL is passed into the sandbox as a `DOC_URL` environment variable.

The code for creating the URL is factored out of `Notifier.ts`. Since the url is a function of the organization as well as the document, some rejiggering is needed to make that information available to DocManager.

On document imports, the new document is registered in the database slightly earlier now, in order to keep the procedure for constructing the URL in different starting conditions more homogeneous.

c879393a8e (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.

Summary:
1. The /import endpoint wasn't handling poor names like ".grist" as
   intended, instead trying to import them using the plugin-based imports.

2. The SaveCopy dialog was allowing users to save to an empty name,
   particularly bad because new docs now default to an empty name.

Error manifested as "Cannot parse data" to the user.

Test Plan: Added tests for both parts of the fix.

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).

Test Plan: existing tests pass
