Renaming table after converting Ref column to RefList didn't work. During table rename, all Refs columns
are converted briefly to Int columns which treats values stored in RefList columns as errors, and stores its

a RecordList object, the RefList column didn't know how to parse that.

self.add_column(

)
elapsed = time.time() - start
print(f"Took {elapsed:.2f} for formula {formula}")

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: While looking at webhooks code, I noticed that it calls `ActiveDoc.fetchQuery` (which I think typically leads to the sandbox method `fetch_table`) with a query on the `id` column, where the values could potentially be all row IDs in the table (e.g. if a new column was added, as in a recent discussion about webhooks gone wrong). This suggests that `fetch_table` should try to avoid using a list for values when possible. In practice this only starts to become an issue at about 10k rows, so I don't know if this has caused any real problems, but it seemed like something worth fixing.
Test Plan:
Extended unit tests for correctness. Tested performance manually. Made a doc with this formula:
```
import time
row_ids = list(Table2.table.row_ids)
query = {"id": row_ids}
start = time.time()
result = table.table._engine.fetch_table('Table2', query=query)
end = time.time()
assert result[1] == row_ids
end - start, len(row_ids)
```
Then put a bunch of rows in `Table2`. This diff made the returned elapsed time much less.

Summary:
Fixes a very specific bug reported here: https://grist.slack.com/archives/C069RUP71/p1694630242765769
The error occurred when:
1. Removing multiple columns simultaneously
2. Those columns were sources of groupby columns for a summary table (so removing them meant recreating the summary table and thus deleting its columns)
3. There was a display column for one of the columns that got deleted (either directly or indirectly) which was set to be automatically removed since it was no longer needed, but this failed because the column was already deleted as part of earlier table removal.
I fixed this by making `apply_auto_removes` remove table records last, so removing the display column wouldn't be a problem.
That fixed the original error, but then I noticed that trying to undo the removal could lead to another error (under even more specific circumstances). It's hard to see exactly why, but I can see that just 3 `RemoveColumn` user actions generated over 100 doc actions and corresponding undo actions, hence the difficulty in narrowing the problem down. This is partly because removing a single column would recreate a summary table, only for that table to be immediately replaced again when another column was removed. Making the frontend send a single `[BulkRemoveRecord, _grist_Tables_column, ...] ` leads to a more efficient and sensible process with about half as many doc actions and no undo error. I think this alone would also solve the original error, but the data engine change seems more generally helpful and worth keeping.

Summary:
Sometimes the model repeats the classes given in the prompt which would mess up extracting the actual formula. This diff solves this by:
1. Changes the generated Python schema so that (a) the thing that needs completing is a plain top level function instead of a property/method inside the class and (2) the classes are fully valid syntax, which makes it easier to
2. Remove classes from the parsed Python code when converting the completion to a formula.
3. Tweak the prompt wording to discourage including classes in general, especially because sometimes the model tries to solve the problem by defining extra methods/attributes/classes.
While I was at it, I changed type hints to use builtins (e.g. `list` instead of `List`) to prevent `from typing import List` which was happening sometimes and would look weird in a formula. Similarly I removed `@dataclass` since that also implies an import, and this also fits with the tweaked wording that the classes are fake.
Test Plan:
Added a new test case to the formula dataset which triggers the unwanted behaviour. The factors that seem to trigger the problem are (1) a small schema so the classes are easier to repeat and (2) the need to import modules, which the model wants to place before all other code. The case failed before this diff and succeeded after. The tweaked wording reduces the chances of repeating the classes but didn't eliminate it, so forcibly removing the classes in Python was needed.
There were also a couple of other existing cases where repeating the classes was observed before but not after.
Overall the score increased from 49 to 51 out of 69 (including the new case). At one point the score was 53, but changes in whitespace were enough to make it drop again.

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`.

Summary:
This tweaks the prompting so that the user's message is given on its own instead of as a docstring within Python. This is so that the prompt makes sense when:
- the user asks a question such as "Can you write me a formula which does ...?" rather than describing their formula as a docstring would, or
- the user sends a message that doesn't ask for a formula at all (https://grist.slack.com/archives/C0234CPPXPA/p1687699944315069?thread_ts=1687698078.832209&cid=C0234CPPXPA)
Also added wording for the model to refuse when the user asks for something that the model cannot do.
Because the code (and maybe in some cases the model) for non-ChatGPT models relies on the prompt consisting entirely of Python code produced by the data engine (which no longer contains the user's message) those code paths have been disabled for now. Updating them now seems like undesirable drag, I think it'd be better to revisit this when iteration/experimentation has slowed down and stabilised.
Test Plan:
Added entries to the formula dataset where the response shouldn't contain a formula, indicated by the value `1` for the new column `no_formula`.
This is somewhat successful, as the model does refuse to help in some of the new test cases, but not all. Performance on existing entries also seems a bit worse, but it's hard to distinguish this from random noise. Hopefully this can be remedied in the future with more work, e.g. automatic followup messages containing example inputs and outputs.

The previous code for extracting a Python formula from the LLM completion involved some shaky string manipulation which this improves on.
Overall the 'test results' from `runCompletion` went from 37/47 to 45/47 for `gpt-3.5-turbo-0613`.
The biggest problem that motivated these changes was that it assumed that code was always inside a markdown code block
(i.e. triple backticks) and so if there was no block there was no code. But the completion often consists of *only* code
with no accompanying explanation or markdown. By parsing the completion in Python instead of JS,
we can easily check if the entire completion is valid Python syntax and accept it if it is.
I also noticed one failure resulting from the completion containing the full function (instead of just the body)
and necessary imports before that function instead of inside. The new parsing moves import inside.

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

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.

Summary:
- When importing into a Ref column, use lookupOne() formula for correct previews.
- When selecting columns to import into a Ref column, now a Numeric column like
'Order' will produce two options: "Order" and "Order (as row ID)".
- Fixes exports to correct the formatting of visible columns. This addresses multiple bugs:
1. Formatting wasn't used, e.g. a Ref showing a custom-formatted date was still presented as YYYY-MM-DD in CSVs.
2. Ref showing a Numeric column was formatted as if a row ID (e.g. `Table1[1.5]`), which is very wrong.
- If importing into a table that doesn't have a primary view, don't switch page after import.

- Generalize GenImporterView to be usable in more cases; removed near-duplicated logic from node side
- Some other refactoring in importing code.
- Fix field/column option selection in ValueParser

This addresses two issues, differently:
- For a formula with leading whitespace, like " 1+1", it is stored as is, but
is fixed to work (it should be valid Python, and whitespace is only stripped out
at parsing time to avoid intentation errors caused by the way it gets parsed)
- For a formula with a leading equals-sign ("="), it is stripped out on the
client side before the formula is stored. Grist documentation uses leading
"=" to indicate formulas (because UI shows an "=" icon), and Excel formulas
actually contain the leading "=", so it is a common mistake to include it.
