bump pyodide version number (#735)
Pyodide packages needed rebuilding, and the pyodide project has
moved on a bit so a new version number is needed. The new packages
have already been built and pushed to S3.

To verify, go to `sandbox/pyodide` and follow the README there.
Then at top level do `GRIST_SANDBOX_FLAVOR=pyodide`. Try to
create and edit a document using formulas. It should work.

fb09b7afa0 (core) Avoid quadratic time complexity in fetch_table with query
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.

9b36fb4dab (core) Fix error in sandbox when removing multiple summary source columns
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.

Test Plan: Added a Python test and an nbrowser test

a1d31e41ad (core) Prevent the AI assistant response from including class definitions
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.

Also adds a related test that I (wrongly) expected to have a similar problem before upgrading asttokens.

Upgrades wrapt for Python 3.11 support. Closes https://github.com/gristlabs/grist-core/issues/534.

Not upgrading the dependencies for Python 2 because pip is giving me errors when I try to install to the `thirdparty` folder. Both these upgrades are motivated by issues specific to Python 3 so this doesn't seem worth pursuing immediately.

391c8ee087 (core) Allow assistant to evaluate current formula
Summary:
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.

c0ed4a8a60 (core) Use a new docker image for tests in Jenkins
Summary:
The image Jenkins used up to now was from 2021. We updated buildtools/jenkins-ec2/Dockerfile since then but couldn't use new image; we can now that an issue with mounts in gvisor has been resolved.

The new image uses newer Chrome (111 vs 95); 111 is the latest version that works with the webdriver version we are using (after that one, copy-pasting tests fail).

In addition, this adds a more precise way to maintain python dependencies: by specifying top-level dependencies in the new core/sandbox/requirements3.in. An updated build step compiles that into requirements3.txt, and syncs venv to that using pip-sync.

This addresses the issue that previously, removing a module from dependencies would not have caused the build to remove it from sandbox_venv3.

Test Plan: Existing tests pass on the new image.

bb7cf6ba20 (core) Modify prompt so that model may say it cannot help with certain requests.
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.

52469c5a7e (core) Improve parsing formula from completion
Summary:
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.

Summary:
For grist-static, we want to the data engine to be able to call external/exported JS functions directly,

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.

603238e966 (core) Adds a UI panel for managing webhooks
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.

such replies nicely).

65013331a3 (core) Fix imports into reference columns, and support two ways to import Numeric as a reference.
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.

Refactorings:
- 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
- Add NUM() helper to turn integer-valued floats into ints, useful for "as row ID" lookups.

Test Plan: Added test cases for imports into reference columns, updated Exports test fixtures.

- For a formula with leading whitespace, like " 1+1", it is stored as is, but

- For a formula with a leading equals-sign ("="), it is stripped out on the

  "=" to indicate formulas (because UI shows an "=" icon), and Excel formulas
  actually contain the leading "=", so it is a common mistake to include it.

logic mistakenly used the inferred name (`MyTable`) in places where the
actual variable name (`myvar`) should have been used.

Additionally, we should not rename local variables, even if they match a
global name.

This fixes both issues.

Test Plan: Added a test case that checks that local variables aren't renamed.

2b2e19c5b5 (core) Fix issue with summary update.
Summary:
The problem is that the implementation for a summary update was relying on type consistency to get columns (ie: matches agains colId and type).

Type consistency is an attempt at maintaining consistent type across same-named column for summaries of same table.

But the problem is that the consistency of types is NOT a strict guarantee or an invariant, more of a best-effort attempt (there are too many possible sequences of operations possible with renaming/adding/removing in summary tables and the underlying table).

With current implementation and with a document violating the type consistency, a summary table could end up with fields referencing columns to the former summary table (more detail below(1)). Which is a bad state (yields js errors on the client).

This diff fixes this issue by relaxing the type comparison when search for same-named column.

(1) __Below is a description of how a violation of type consistency could end-up in bad state document (example taken from the reported bug):__

> In this document, let's assume two summary tables `Table1 [by A]` and `Table1 [Totals]`. Let's also assume Table1 and `Table1 [Totals]` both have an `Amount(Numeric)` column, and that `Table1 [by A]` has one `Amount(Any)` column (violating the type consistency principle). Now when users wanted to change the `Table1 [Totals]` section to group by 'A', grist found that there is already a summary table with same grouping. But it couldn't find a matching column for `Amount(Numeric)` so it created a new one. Except that because there was still an `Amount(Any)` the new column was named `Amount2` which caused following code to ignore it and in particular forgetting to update it's corresponding section's field which was then pointing toward the column of a different table (which is bad).

Test Plan: Added python test.

efd92c6c2a (core) Two fixes to tests affected by changes that came from grist-core.
Summary:
- For python2, skip some tests of renaming which produce different results
  because of an un-upgradable astroid version.
- Fix test affected by pyCall() having changed to async; avoid hanging timeout
  callback in case of error.

Test Plan: All test cases should now pass (with 4 getting skipped)

add a pyodide-based "sandbox" flavor (#437)
This adds a new `GRIST_SANDBOX_FLAVOR=pyodide` option where the
version of Python used for the data engine is wasm, and so can
be run by node like the rest of the back end. It still runs as
a separate process.

There are a few small version changes made to packages to avoid
various awkwardnesses present in the current versions. All existing
tests pass.

This is very experimental. To use, you'll need something with
a bash shell and make. First do:
```
cd sandbox/pyodide
make setup           # README.md and Makefile have details
cd ..
```

Then running Grist as:
```
GRIST_SANDBOX_FLAVOR=pyodide yarn start
```
should work. Adding a formula with content:
```
import sys; return sys.version
```
should return a different Python version than other sandboxes.

The motivation for this work is to have a form of sandboxing
that will work on Windows for Grist Electron (for Linux we have
gvisor/runsc, for Mac we have sandbox-exec, but I haven't found
anything comparable for Windows).

It also brings a back-end-free version of Grist a bit closer, for
use-cases where that would make sense - such as serving a report
(in the form of a Grist document) on a static site.
