56624c4a95 (core) Fix undo error for automatically removed rows, especially in summary tables
Summary:
Fixes a bug noted here: https://grist.slack.com/archives/C069RUP71/p1662564341132349

This bug could happen quite easily as follows:

1. Have a formula in a summary table such as `$group.amount`. Typically there's also a `SUM` but that's not essential.
2. Find a group with nonzero values of `amount`.
3. Delete all rows in that group in the source table. Typically that just means one row in a lonely group.
4. The summary table row is automatically deleted.
5. Try to undo. This raises an error about trying to update a non-existent summary table row.

I tried to account for this undo problem in https://phab.getgrist.com/D3489 by not saving the updated value for `$group` when it was found to be empty. The reason this was insufficient is that `$group.amount` is immediately invalidated anyway when the source row(s) are deleted (I think because that's just how dependency relations involving references work) *and* the calculated value of `$group.amount` changes even if `$group` doesn't. For example, `$group.amount` may have previously been `[100, 200]`. After deleting the rows, `$group.amount` becomes `[0, 0]`. Keeping `$group` unchanged prevents `$group.amount` from just being `[]`, but deleting the source rows means that the amounts become the numeric default `0` which is still a change. This change in value is then noted which leads to saving an undo action to update the summary table record. All this happens in step 3 above, and the summary record is only deleted after that point.

This diff removes that special handling for `group` and instead adds a more general fix to `action_summary.py`. This inserts undo actions for deleted rows at the beginning of the undo list rather than at the end, which was already done for deleted tables and columns.

Fix columns with falsy cells wrongly parsed as dates (#276)
Eg. before this commit, this table would result in Date columns:

| A     | B |
| ----- | -- |
| FALSE | 0 |

For now, even FALSE is parsed as Numeric (not sure why we don't have
a BooleanConverter).

bde44323c5 (core) apply some dependabot suggestions
Summary:
This applies the set of dependabot suggestions that are currently
passing tests on grist-core. There are a lot more suggestions to
come, an unusual number are not passing tests because tests were
briefly broken.

The list of suggestions is extracted from:

https://api.github.com/repos/gristlabs/grist-core/pulls?search=status:success+state:open

And then applied using:

  yarn upgrade package1@version1 package2@version2 ....

After application, any new entries in package.json are pruned, leaving
just updated entries and yarn.lock changes.

Non-trivial code updates include:
 * A change related to axios typing
 * A change related to jquery dropping `size()` in favor of `length`

42afb17e36 (core) Run and test imports only in Python 3, upgrade openpyxl, fix weird date handling
Summary:
Python 2 only needs to be supported for the sake of old documents and formulas. This doesn't apply to the separate sandboxes that parse files for imports. Using Python 3 only allows using newer libraries and library versions. In particular, the latest version of openpyxl doesn't support Python 2. This will also make it easier to make other similar changes in the future, such as replacing messytables with a modern library. See https://grist.slack.com/archives/C0234CPPXPA/p1661261829343999?thread_ts=1661260442.837959&cid=C0234CPPXPA

The latest openpyxl is better at handling a particular edge case with broken dates in Excel, but still doesn't quite do what we want, so we monkeypatch it. Discussion: https://grist.slack.com/archives/C02EGJ1FUCV/p1661440851911869?thread_ts=1661154219.515549&cid=C02EGJ1FUCV

Setting `preferredPythonVersion` to '3' in SafePythonComponent ensures that JS always creates import sandboxes that use Python 3. Within Python, a module used by all imports will raise an error in Python 2. Python unit tests of imports are now only run in Python 3, using the `load_tests` protocol of `unittest`.

Test Plan: Mostly existing tests. Added another strange date to the Excel fixture.

42060df29a (core) Formula autocomplete improvements for references and lookups
Summary:
Makes the following improvements to formula autocomplete:

- When a user types `$RefCol` (or part of it), also show `$RefCol.VisibleCol` (replace actual column names) in the autocomplete even before the `.` is typed, to help users understand the difference between a raw reference/record and its visible column.
- When a user types a table name, show `.lookupOne` and `.lookupRecords` in the autocomplete, again even before the `.` is typed.
- For `.lookupRecords(` and `.lookupOne(`, once the `(` is entered, suggest each column name as a keyword argument.
- Also suggest lookup arguments involving compatible reference columns, especially 'reverse reference' lookups like `refcol=$id` which are very common and difficult for users.
- To support these features, the Ace editor autocomplete needs some patching to fetch fresh autocomplete options after typing `.` or `(`. This also improves unrelated behaviour that wasn't great before when one column name is contained in another. See the first added browser test.

b416a5c4b1 (core) Fix error when updating summary table formulas after rename
Summary:
Formulas in summary tables were being associated with the source table for automatic updating. When a table/column was renamed such that the formula needed to update to match, it would look for a column with the same colId but in the source table. Such a column might not exist which would lead to an error, or if it existed then the update would be wrong.

This association was created while building formulas to display in the code view in a nested `_Summary` class, it didn't need to exist at all. So this diff simply prevents the association from being created.

083a0ec000 (core) Allow using MIN and MAX functions with dates/datetimes
Summary:
The MIN and MAX functions for formulas previously only considered numbers, ignoring other types, including dates. An example of this being a problem is here: https://community.getgrist.com/t/last-field-circularreferror-what-is-it/1114/4 . Using `MIN` on a column of dates would return 0 (the default) which gets converted to 1970-01-01. Users have to use `min` instead, which is confusing, and doesn't work when some values are empty.

This diff lets the functions operate on date and datetime values. A mixture of dates and datetimes is allowed, even though these cannot usually be compared in Python. Mixing dates and numbers will raise an exception.

b8486dcdba (core) Nice summary table IDs
Summary:
Changes auto-generated summary table IDs from e.g. `GristSummary_6_Table1` to `Table1_summary_A_B` (meaning `Table1` grouped by `A` and `B`). This makes it easier to write formulas involving summary tables, make API requests, understand logs, etc.

Because these don't encode the source table ID as reliably as before, `decode_summary_table_name` now uses the summary table schema info, not just the summary table ID. Specifically, it looks at the type of the `group` column, which is `RefList:<source table id>`.

Renaming a source table renames the summary table as before, and now renaming a groupby column renames the summary table as well.

Conflicting table names are resolved in the usual way by adding a number at the end, e.g. `Table1_summary_A_B2`. These summary tables are not automatically renamed when the disambiguation is no longer needed.

A new migration renames all summary tables to the new scheme, and updates formulas using summary tables with a simple regex.

Test Plan:
Updated many tests to use the new style of name.

Added new Python tests to for resolving conflicts when renaming source tables and groupby columns.

Added a test for the migration, including renames in formulas.

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

> Problem: user creates fresh new empty column. Users with access to write to that column, but not modify schema, will not in fact be able to write into it (since on first data entry column type needs to change). Experience is confusing.

Refactored `enter_indirection` and `leave_indirection` to a single context manager method for use with `with` instead of `try/finally`.

Used the new method in `_ensure_column_accepts_data` around column changing actions converting empty column to data column.

Test Plan:
Updated a Python test, reflecting that the correct actions are now marked as direct=False.

Tested manually that I can now add data to a blank column without schema access, while I wasn't able to before, and I still can't make other schema changes.

3ad2d9212e (core) Prevent rebuilding usercode for every AddColumn when importing
Summary:
Importing a file with many columns would be very slow due to expensive calls to rebuild_usercode for each added column: https://grist.slack.com/archives/C02EGJ1FUCV/p1652395747972749?thread_ts=1652388644.394419&cid=C02EGJ1FUCV

This diff suppresses rebuild_usercode temporarily while adding columns in a loop in MakeImportTransformColumns, then calls it once afterwards.

Test Plan: Manually imported a wide file repeatedly. Eventually, whehn importing a file with 300 columns, generating the preview went from taking about 100 seconds to 20 seconds.

fb575a8b7e (core) Ensure formulas return something and don't assign to attributes of rec
Summary: To help with mistakes in formulas, forbid assigning to attributes of `rec` (e.g. `$foo = 1` which should probably be `==`) and ensure that there is at least one `return` in the formula (after maybe adding an implicit one at the end).

Test Plan: Extended Python unit test, updated tests which were missing return.

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.

Test Plan: added tests

e6983e9209 (core) add machinery for self-managed flavor of Grist
Summary:
Currently, we have two ways that we deliver Grist. One is grist-core,
which has simple defaults and is relatively easy for third parties to
deploy. The second is our internal build for our SaaS, which is the
opposite. For self-managed Grist, a planned paid on-premise version
of Grist, I adopt the following approach:

 * Use the `grist-core` build mechanism, extending it to accept an
   overlay of extra code if present.
 * Extra code is supplied in a self-contained `ext` directory, with
   an `ext/app` directory that is of same structure as core `app`
   and `stubs/app`.
 * The `ext` directory also contains information about extra
   node dependencies needed beyond that of `grist-core`.
 * The `ext` directory is contained within our monorepo rather than
   `grist-core` since it may contain material not under the Apache
   license.

Docker builds are achieved in our monorepo by using the `--build-context`
functionality to add in `ext` during the regular `grist-core` build:

```
docker buildx build --load -t gristlabs/grist-ee --build-context=ext=../ext .
```

Incremental builds in our monorepo are achieved with the `build_core.sh` helper,
like:

```
buildtools/build_core.sh /tmp/self-managed
cd /tmp/self-managed
yarn start
```

The initial `ext` directory contains material for snapshotting to S3.
If you build the docker image as above, and have S3 access, you can
do something like:

```
docker run -p 8484:8484 --env GRIST_SESSION_SECRET=a-secret \
  --env GRIST_DOCS_S3_BUCKET=grist-docs-test \
  --env GRIST_DOCS_S3_PREFIX=self-managed \
  -v $HOME/.aws:/root/.aws -it gristlabs/grist-ee
```

This will start a version of Grist that is like `grist-core` but with
S3 snapshots enabled. To release this code to `grist-core`, it would
just need to move from `ext/app` to `app` within core.

I tried a lot of ways of organizing self-managed Grist, and this was
what made me happiest. There are a lot of trade-offs, but here is what
I was looking for:

 * Only OSS-code in grist-core. Adding mixed-license material there
   feels unfair to people already working with the repo. That said,
   a possible future is to move away from our private monorepo to
   a public mixed-licence repo, which could have the same relationship
   with grist-core as the monorepo has.
 * Minimal differences between self-managed builds and one of our
   existing builds, ideally hewing as close to grist-core as possible
   for ease of documentation, debugging, and maintenance.
 * Ideally, docker builds without copying files around (the new
   `--build-context` functionality made that possible).
 * Compatibility with monorepo build.

Expressing dependencies of the extra code in `ext` proved tricky to
do in a clean way. Yarn/npm fought me every step of the way - everything
related to optional dependencies was unsatisfactory in some respect.
Yarn2 is flexible but smells like it might be overreach. In the end,
organizing to install non-core dependencies one directory up from the
main build was a good simple trick that saved my bacon.

This diff gets us to the point of building `grist-ee` images conveniently,
but there isn't a public repo people can go look at to see its source. This
could be generated by taking `grist-core`, adding the `ext` directory
to it, and pushing to a distinct repository. I'm not in a hurry to do that,
since a PR to that repo would be hard to sync with our monorepo and
`grist-core`. Also, we don't have any licensing text ready for the `ext`
directory. So leaving that for future work.

6c90de4d62 (core) Switch excel import parsing from messytables+xlrd to openpyxl, and ignore empty rows
Summary:
Use openpyxl instead of messytables (which used xlrd internally) in import_xls.py.

Skip empty rows since excel files can easily contain huge numbers of them.

Drop support for xls files (which openpyxl doesn't support) in favour of the newer xlsx format.

Fix some details relating to python virtualenvs and dependencies, as Jenkins was failing to find new Python dependencies.

Test Plan: Mostly relying on existing tests. Updated various tests which referred to xls files instead of xlsx. Added a Python test for skipping empty rows.

Summary:
A new way for renaming tables.

  - There is a new popup to rename section (where you can also rename the table)
  - Renaming/Deleting page doesn't modify/delete the table.
  - Renaming table can rename a page if the names match (and the page contains a section with that table).
  - User can rename table in Raw Data UI in two ways - either on the listing or by using the section name popup
  - As before, there is no way to change tableId - it is derived from a table name.
  - When the section name is empty the table name is shown instead.
  - White space for section name is allowed (to discuss) - so the user can just paste '   '.
  - Empty name for a page is not allowed (but white space is).
  - Some bugs related to deleting tables with attached summary tables (and with undoing this operation) were fixed (but not all of them yet).

Test Plan: Updated tests.

0829ae67ef (core) Fixing hidden col missing after summary update
Summary:
Updating one summary groupby columns is handle by the
`update_summary_section`. That routine is in charge of creating a new
summary table and transfer all possible columns from old table to the
new one, so that the new table appear to change only the minimum to
users.

The problem that this diff address is that, the logic to decide what columns we need to keep, only applies to the visible
fields and ignore the hidden columns, causing all hidden columns to be removed. This diff, simply
changes that routine to address all columns.

the mutliple fixes on the test_summary2.py result from a change of
ordering of columns: the culprit is the `group` columns, which is by
default a hidden columns and that had to be explicitely added back to
the new summary table. It is now transferred automatically, like other
columns, which does cause a little change of ordering on the db. This
should not result in any display order changes for the users.
