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.

Summary:
This removes problematic code that was holding a HomeDB transaction while applying user actions which could hang indefinitely, especially if the webhook queue is full as in https://grist.slack.com/archives/C05DBJ6LA1F/p1698159750945949.
The discussion about adding this code is here: https://phab.getgrist.com/D3821#inline-45054
The initial motivation was to roll back HomeDB changes if something went wrong while applying user actions, to avoid saving only part of the changes the user requested. I think it's actually fine to just allow such a partial save to happen - I don't see anything particularly undesirable about keeping an update to the webhook URL if other updates requested by the user didn't also get applied, as the fields don't affect each other.
The comment approving the transaction approach said "so we shouldn't end up leave the transaction hanging around too long" which has been falsified.
It looks like there was also some desire to prevent a mess caused by multiple simultaneous calls to this endpoint, which the transaction may have helped with a little, but didn't really seem like a solution. Comments in `Triggers.ts` also mention fears of race conditions when clearing (some of) the queue and the need for some locking. So I wrapped all webhook-related endpoints in a simple `Mutex` held by the `ActiveDoc` to prevent simultaneous changes. I *think* this is a good thing. These endpoints shouldn't be called frequently enough to create a performance issue, and this shouldn't affect actually sending webhook events when records are added/updated. And it does seem like interleaving calls to these endpoints could cause very weird problems.
Test Plan: Nothing yet, I'd like to hear if others think this is sensible.

Summary:
Add two shutdown-related timeouts.
1. One is to limit the duration of any work that happens once shutdown
begins. In particular, waiting for an update to current time could block
indefinitely if the data engine is unresponsive. Such awaits are now
limited to 5 seconds.
2. The other is to allow documents to get shutdown for inactivity even when
some work takes forever. Certain work (e.g. applying user actions)
generally prevents a document from shutting down while it's pending. This
prevention is now limited to 5 minutes.
Shutting down a doc while something is pending may break some
assumptions, and lead to errors. The timeout is long to let us assume
that the work is stuck, and that errors are better than waiting forever.
Other changes:
- Periodic ActiveDoc work (intervals) is now started when a doc finishes
loading rather than in the constructor. The difference only showed up in
tests which makes the intervals much shorter.
- Move timeoutReached() utility function to gutil, and use it for
isLongerThan(), since they are basically identical. Also makes sure that the
timer in these is cleared in all cases.
- Remove duplicate waitForIt implementation (previously had a copy in both
test/server and core/test/server).
- Change testUtil.captureLog to pass messages to its callback, to allow asserts
on messages within the callback.
Test Plan:
Added new unittests for the new shutdowns, including a replication
of a bad state that was possible during shutdown.

Replaces https://phab.getgrist.com/D3940, particularly to avoid doing potentially unwanted things automatically.
Adds optional fields `evaluateCurrentFormula?: boolean; rowId?: number` to `FormulaAssistanceContext` (part of `AssistanceRequest`). When `evaluateCurrentFormula` is `true`, calls a new function `evaluate_formula` in the sandbox which computes the existing formula in the column (regardless of anything the AI may have suggested) and uses that to generate an additional system message which is added before the user's message. In theory this could be used in an interface where users ask why a formula doesn't work, including possibly a formula suggested by the AI. For now, it's only used in `runCompletion_impl.ts` for experimenting.
Also cleaned up a bit, removing `_chatMode` which is always `true` now, and uses of `regenerate` which is always `false`.
Test Plan: Updated `runCompletion_impl` to optionally use the new feature, in which case it now scores 51/68 instead of 49/68.

For grist-static, we want to the data engine to be able to call external/exported JS functions directly,
rather than via the node 'server' living in another thread which requires synchronous communication hackery.
As a step in that direction, this diff changes the exported functions that we care about (guessColInfo and convertFromColumn)
to just using the top-level functions instead of relying on fields in ActiveDoc, namely docData.
For guessColInfo, this is done by directly passing the small amount of metadata that was previously retrieved from the DocData.
For convertFromColumn, disentangling DocData is a lot more complicated, so instead we construct a fresh DocData object using
the required metadata tables which are now passed in by the data engine.

Summary:
This adds a UI panel for managing webhooks. Work started by Cyprien Pindat. You can find the UI on a document's settings page. Main changes relative to Cyprien's demo:
* Changed behavior of virtual table to be more consistent with the rest of Grist, by factoring out part of the implementation of on-demand tables.
* Cell values that would create an error can now be denied and reverted (as for the rest of Grist).
* Changes made by other users are integrated in a sane way.
* Basic undo/redo support is added using the regular undo/redo stack.
* The table list in the drop-down is now updated if schema changes.
* Added a notification from back-end when webhook status is updated so constant polling isn't needed to support multi-user operation.
* Factored out webhook specific logic from general virtual table support.
* Made a bunch of fixes to various broken behavior.
* Added tests.
The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case.
I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error.
I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end. Sneaky.
Contains a migration, so needs an extra reviewer for that.

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.
