472a9a186e (core) control the distribution of attachment metadata
Summary:
for users who don't automatically have deep rights
to the document, provide them with attachment metadata only
for rows they have access to. This is a little tricky to
do efficiently. We provide attachment metadata when an
individual table is fetched, rather than on initial document
load, so we don't block that load on a full document scan.
We provide attachment metadata to a client when we see that
we are shipping rows mentioning particular attachments,
without making any effort to keep track of the metadata they
already have.

629fcccd5a (core) Adding /webhooks endpoint
Summary:
- New /webhooks event that lists all webhooks in a document (available for owners),
- Monitoring webhooks usage and saving it in memory or Redis,
- Loosening _usubscribe API endpoint, so that the information returned from the /webhook endpoint is enough to unsubscribe,
- Owners can remove webhook without the unsubscribe key.

The endpoint lists all webhooks that are registered in a document, not just webhooks from a single table.
There are two status fields. First for the webhook, second for the last request attempt.
Webhook can have 5 statuses: 'idle', 'sending', 'retrying', 'postponed', 'error', which roughly describes what the
sendLoop is currently doing. The 'error' status describes a situation when all request attempts failed and the queue needs
to be drained, so some requests were dropped.

The last request status can only be: 'success', 'failure' or 'rejected'. Rejected means that the last batch was dropped because the
queue was too long.

ea71312d0e (core) deal with write access for attachments
Summary:
Attachments are a special case for granular access control. A user is now allowed to read a given attachment if they have read access to a cell containing its id. So when a user writes to a cell in an attachment column, it is important that they can only write the ids of cells to which they have access. This diff allows a user to add an attachment id in a cell if:

  * The user already has access to that a attachment via some existing cell, or
  * The user recently updated the attachment, or
  * The attachment change is from an undo/redo of a previous action attributed to that user

792565976a (core) Show example values in formula autocomplete
Summary:
This diff adds a preview of the value of certain autocomplete suggestions, especially of the form `$foo.bar` or `user.email`. The main initial motivation was to show the difference between `$Ref` and `$Ref.DisplayCol`, but the feature is more general.

The client now sends the row ID of the row being edited (along with the table and column IDs which were already sent) to the server to fetch autocomplete suggestions. The returned suggestions are now tuples `(suggestion, example_value)` where `example_value` is a string or null. The example value is simply obtained by evaluating (in a controlled way) the suggestion in the context of the given record and the current user. The string representation is similar to the standard `repr` but dates and datetimes are formatted, and the whole thing is truncated for efficiency.

The example values are shown in the autocomplete popup separated from the actual suggestion by a number of spaces calculated to:

1. Clearly separate the suggestion from the values
2. Left-align the example values in most cases
3. Avoid having so much space such that connecting suggestions and values becomes visually difficult.

The tokenization of the row is then tweaked to show the example in light grey to deemphasise it.

Main discussion where the above was decided: https://grist.slack.com/archives/CDHABLZJT/p1661795588100009

The diff also includes various other small improvements and fixes:

- The autocomplete popup is much wider to make room for long suggestions, particularly lookups, as pointed out in https://phab.getgrist.com/D3580#inline-41007. The wide popup is the reason a fancy solution was needed to position the example values. I didn't see a way to dynamically resize the popup based on suggestions, and it didn't seem like a good idea to try.
- The `grist` and `python` labels previously shown on the right are removed. They were not helpful (https://grist.slack.com/archives/CDHABLZJT/p1659697086155179) and would get in the way of the example values.
- Fixed a bug in our custom tokenization that caused function arguments to be weirdly truncated in the middle: https://grist.slack.com/archives/CDHABLZJT/p1661956353699169?thread_ts=1661953258.342739&cid=CDHABLZJT and https://grist.slack.com/archives/C069RUP71/p1659696778991339
- Hide suggestions involving helper columns like `$gristHelper_Display` or `Table.lookupRecords(gristHelper_Display=` (https://grist.slack.com/archives/CDHABLZJT/p1661953258342739). The former has been around for a while and seems to be a mistake. The fix is simply to use `is_visible_column` instead of `is_user_column`. Since the latter is not used anywhere else, and using it in the first place seems like a mistake more than anything else, I've also removed the function to prevent similar mistakes in the future.
- Don't suggest private columns as lookup arguments: https://grist.slack.com/archives/CDHABLZJT/p1662133416652499?thread_ts=1661795588.100009&cid=CDHABLZJT
- Only fetch fresh suggestions specifically after typing `lookupRecords(` or `lookupOne(` rather than just `(`, as this would needlessly hide function suggestions which could still be useful to see the arguments. However this only makes a difference when there are still multiple matching suggestions, otherwise Ace hides them anyway.

Test Plan: Extended and updated several Python and browser tests.

7078922a65 (core) ensure randomness works when sandbox is cloned from a checkpoint
Summary:
This calls a new `initialize` method on the sandbox before we start
doing calculations with it, to make sure that `random.seed()` has
been called. Otherwise, if the sandbox is cloned from a checkpoint,
the seed will have been reset.

The `initialize` method includes the functionality previously done
by `set_doc_url` since it is also initialization/personalization and
this way we avoid introducing another round trip to the sandbox.

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.

f91f45b26d (core) support granular read access for attachments
Summary:
When a user requests to read the contents of an attachment, only allow the request if there exists a cell in an attachment column that contains the attachment and which they have read access to.

This does not cover:
 * Granular write access for attachments. In particular, a user who can write to any attachment column should be considered to have full read access to all attachment columns, currently.
 * Access control of attachment metadata such as name and format.

The implementation uses a sql query that requires a scan, and some notes on how this could be optimized in future. The web client was updated to specify the cell to check for access, and performance seemed fine in casual testing on a doc with 1000s of attachments. I'm not sure how performance would hold up as the set of access rules grows as well.

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.

9fffb491f9 (core) External requests
Summary:
Adds a Python function `REQUEST` which makes an HTTP GET request. Behind the scenes it:

- Raises a special exception to stop trying to evaluate the current cell and just keep the existing value.
- Notes the request arguments which will be returned by `apply_user_actions`.
- Makes the actual request in NodeJS, which sends back the raw response data in a new action `RespondToRequests` which reevaluates the cell(s) that made the request.
- Wraps the response data in a class which mimics the `Response` class of the `requests` library.

In certain cases, this asynchronous flow doesn't work and the sandbox will instead synchronously call an exported JS method:

- When reevaluating a single cell to get a formula error, the request is made synchronously.
- When a formula makes multiple requests, the earlier responses are retrieved synchronously from files which store responses as long as needed to complete evaluating formulas. See https://grist.slack.com/archives/CL1LQ8AT0/p1653399747810139

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.

Call ActiveDoc.removeUnusedAttachments every hour using setInterval, and in ActiveDoc.shutdown (which also clears said interval).

Unrelated: small fix to my webhooks code which was creating a redis client on shutdown just to quit it.

Test Plan:
Tweaked DocApi test to remove expired attachments by force-reloading the doc, so that it removes them during shutdown. Extracted a new testing endpoint /verifyFiles to support this test (previously running that code only happened with `/removeUnused?verifyfiles=1`).

Tested the setInterval part manually.

64a5c79dbc (core) Limit total attachment file size per document
Summary:
- Add a new parameter `Features.baseMaxAttachmentsBytesPerDocument` and set it to 1GB for the free team product.
- Add a method to DocStorage to calculate the total size of existing and used attachments.
- Add a migration to DocStorage adding an index to make the query in the above method fast.
- Check in ActiveDoc if uploading attachment(s) would exceed the product limit on that document.

Test Plan: Added test in `limits.ts` testing enforcement of the attachment limit.

Summary: Adds methods to delete metadata rows based on timeDeleted. The flag expiredOnly determines if it only deletes attachments that were soft-deleted 7 days ago, or just all soft-deleted rows. Then any actual file data that doesn't have matching metadata is deleted.

21b0ac3eff (core) Enforcing data size limit
Summary:
Track 'data size' in ActiveDoc alongside row count. Measure it at most once every 5 minutes after each change as before, or after every change when it becomes high enough to matter.

A document is now considered to be approaching/exceeding 'the data limit' if either the data size or the row count is approaching/exceeding its own limit.

Unrelated: tweaked teamFreeFeatures.snapshotWindow based on Quip comments

Test Plan: Tested manually that data size is now logged after every change once it gets high enough, but only if the row limit isn't also too high. Still too early for automated tests.

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.

See also the tasks mentioned in https://phab.getgrist.com/D3331

Test Plan: Extended FreeTeam nbrowser test, testing the 4 statuses.

134ae99e9a (core) add gvisor-based sandboxing to core
Summary:
This adds support for gvisor sandboxing in core. When Grist is run outside of a container, regular gvisor can be used (if on linux), and will run in rootless mode. When Grist is run inside a container, docker's default policy is insufficient for running gvisor, so a fork of gvisor is used that has less defence-in-depth but can run without privileges.

Sandboxing is automatically turned on in the Grist core container. It is not turned on automatically when built from source, since it is operating-system dependent.

This diff may break a complex method of testing Grist with gvisor on macs that I may have been the only person using. If anyone complains I'll find time on a mac to fix it :)

This diff includes a small "easter egg" to force document loads, primarily intended for developer use.

Test Plan: existing tests pass; checked that core and saas docker builds function

02e69fb685 (core) Crudely show row count and limit in UI
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.

f02174eb7e (core) Fix error when canceling import
Summary:
If cancel was clicked while a transform section was still being
generated in the Importer, an error was thrown. This refactors
the cancelImportFiles API action to take in the file upload id
in place of the entire DataSourceTransformed parameter, which
contains other values that are irrelevant to canceling. One of those
values, the transform section id, was causing the error to be thrown
since it was momentarily null.

Test Plan: Tested manually.

599545fb11 (core) Fuller guessing of type and options when adding first data to blank columns
Summary:
Adds `common/ValueGuesser.ts` with logic for guessing column type and widget options (only for dates/datetimes) from an array of strings, and converting the strings to the guessed type in a lossless manner, so that converting back to Text gives the original values.

Changes `_ensure_column_accepts_data` in Python to call an exported JS method using the new logic where possible.

Test Plan: Added `test/common/ValueGuesser.ts` to unit test the core guessing logic and a DocApi end-to-end test for what happens to new columns.

Summary: This is https://phab.getgrist.com/D3205 plus some changes (https://github.com/dsagal/grist/compare/type-convert...type-convert-server?expand=1) that move the conversion process to the backend. A new user action ConvertFromColumn uses `call_external` so that the data engine can delegate back to ActiveDoc. Code for creating formatters and parsers is significantly refactored so that most of the logic is in `common` and can be used in different ways.

Test Plan: The original diff adds plenty of tests.

e0fb281eba (core) When searching, use formatter.formatAny() to handle values of invalid type.
Summary:
This turns out necessary because ReferenceList columns are formatted
using the formatter of the associated visibleCol. This works correctly
in dedicated widgets, but in generic code (like SearchModel here), this
formatter needs to handle unexpected values (of type ReferenceList).

Without the fix, it produces JS errors when search reaches a
RefList:<Date> column.

A better fix would allow a formatter to know that it expects a ReferenceList,
AND to know how to format each value of it, but that's a bigger question
that's outside the scope of this fix.

Test Plan: Includes a browser test which reproduces the bug.

d1a848b44a (core) Parse string cell values in Doc API and Imports
Summary:
- Adds a function `parseUserAction` for parsing strings in UserActions to `ValueParser.ts`
- Adds a boolean option `parseStrings` to use `parseUserAction` in `ActiveDoc.applyUserActions`, off by default.
- Uses `parseStrings` by default in DocApi (set `?noparse=true` in a request to disable) when adding/updating records through the `/data` or `/records` endpoints or in general with the `/apply` endpoint.
- Uses `parseStrings` for various actions in `ActiveDocImport`. Since most types are parsed in Python before these actions are constructed, this only affects references, which still look like errors in the import preview. Importing references can also easily still run into more complicated problems discussed in https://grist.slack.com/archives/C0234CPPXPA/p1639514844028200

Test Plan:
- Added tests to DocApi to compare behaviour with and without string parsing.
- Added a new browser test, fixture doc, and fixture CSV to test importing a file containing references.
