e1780e4f58 (core) Migrate import code from data engine to Node
Summary:
Finishing imports now occurs in Node instead of the
data engine, which makes it possible to import into
on-demand tables. Merging code was also refactored
and now uses a SQL query to diff source and destination
tables in order to determine what to update or add.

Also fixes a bug where incremental imports involving
Excel files with multiple sheets would fail due to the UI
not serializing merge options correctly.

Test Plan: Browser tests.

d4626aea82 (core) Only update changed records with RenameChoices
Summary:
Make _rename_cell_choice return None for unchanged values

The tests actually passs without the implementation changes, because trim_update_action removed the noop updates. So I'm not sure if this is an improvement. It certainly seems that it would be slower in cases where every record is updated, and it's hard to say if it would be better in other cases.

Test Plan:
Checked doc actions in existing test.
Also tested for invalid existing values.

b3b7410ede (core) open documents without blocking on data engine
Summary:
With this diff, when a user opens a Grist document in a browser, they will be able to view its contents without waiting for the data engine to start up. Once the data engine starts, it will run a calculation and send any updates made. Changes to the document will be blocked until the engine is started and the initial calculation is complete.

The increase in responsiveness is useful in its own right, and also reduces the impact of an extra startup time in a candidate next-generation sandbox.

A small unrelated fix is included for `core/package.json`, to catch up with a recent change to `package.json`.

A small `./build schema` convenience is added to just rebuild the typescript schema file.

Test Plan: added test; existing tests pass - small fixes needed in some cases because of new timing

3c4d71aeca (core) Initial webhooks implementation
Summary:
See https://grist.quip.com/VKd3ASF99ezD/Outgoing-Webhooks

- 2 new DocApi endpoints: _subscribe and _unsubscribe, not meant to be user friendly or publicly documented. _unsubscribe should be given the response from _subscribe in the body, e.g:

```
$ curl -X POST -H "Authorization: Bearer 8fd4dc59ecb05ab29ae5a183c03101319b8e6ca9" "http://localhost:8080/api/docs/6WYa23FqWxGNe3AR6DLjCJ/tables/Table2/_subscribe" -H "Content-type: application/json" -d '{"url": "https://webhook.site/a916b526-8afc-46e6-aa8f-a625d0d83ec3", "eventTypes": ["add"], "isReadyColumn": "C"}'
{"unsubscribeKey":"3246f158-55b5-4fc7-baa5-093b75ffa86c","triggerId":2,"webhookId":"853b4bfa-9d39-4639-aa33-7d45354903c0"}
$ curl -X POST -H "Authorization: Bearer 8fd4dc59ecb05ab29ae5a183c03101319b8e6ca9" "http://localhost:8080/api/docs/6WYa23FqWxGNe3AR6DLjCJ/tables/Table2/_unsubscribe" -H "Content-type: application/json" -d '{"unsubscribeKey":"3246f158-55b5-4fc7-baa5-093b75ffa86c","triggerId":2,"webhookId":"853b4bfa-9d39-4639-aa33-7d45354903c0"}'
{"success":true}
```

- New DB entity Secret to hold the webhook URL and unsubscribe key
- New document metatable _grist_Triggers subscribes to table changes and points to a secret to use for a webhook
- New file Triggers.ts processes action summaries and uses the two new tables to send webhooks.
- Also went on a bit of a diversion and made a typesafe subclass of TableData for metatables.

I think this is essentially good enough for a first diff, to keep the diffs manageable and to talk about the overall structure. Future diffs can add tests and more robustness using redis etc. After this diff I can also start building the Zapier integration privately.

Test Plan: Tested manually: see curl commands in summary for an example. Payloads can be seen in https://webhook.site/#!/a916b526-8afc-46e6-aa8f-a625d0d83ec3/0b9fe335-33f7-49fe-b90b-2db5ba53382d/1 . Great site for testing webhooks btw.

7907467dbc (core) treat summary tables like formulas for access control purposes
Summary:
This unsets the `direct` flag for actions emitted when summary tables are updated. That means those actions will be ignored for access control purposes. So if a user has the right to change a source table, the resulting changes to the summary won't result in the overall action bundle being forbidden.

I don't think I've actually seen the use case that inspired this issue being filed. I could imagine perhaps a user forbidden from creating rows globally making permitted updates that could add rows in a summary (and it being desirable to allow that).

8a7edb6257 (core) Enable incremental imports
Summary:
The import dialog now has an option to 'Update existing records',
which when checked will allow for selection of 1 or more fields
to match source and destination tables on.

If all fields match, then the matched record in the
destination table will be merged with the incoming record
from the source table. This means the incoming values will
replace the destination table values, unless the incoming
values are blank.

Additional merge strategies are implemented in the data
engine, but the import dialog only uses one of the
strategies currently. The others can be exposed in the UI
in the future, and tweak the behavior of how source
and destination values should be merged in different contexts,
such as when blank values exist.

Test Plan: Python and browser tests.

5258fa649d (core) Fix self-updating trigger formulas used in lookups
Summary:
The problem: For a data-cleaning column (one that depends on itself) `doBulkUpdateRecord` calls `prevent_recalc(should_prevent=False)``
which is supposed to cause it to get calculated eventually.
But before that it calls `_do_doc_action` -> `apply_doc_action` -> `_bring_lookups_up_to_date` which recalculates
a lookup column which eventually calls `_recompute_step(allow_evaluation=False)` on the data-cleaning column
which shouldn't really do anything significant but it both modifies the set `self.recompute_map[node]`
and then removes it from the map after it's empty.

The solution: when `allow_evaluation=False` and `self._prevent_recompute_map[node]` is nonempty,
ensure `self.recompute_map[node]` is not modified,
and check the map directly (instead of `dirty_rows` which can now be separate) to see if the set is empty before cleanup.

Test Plan: Added a lookup column to test_self_trigger, ensured that this caused the test to fail without the other two changes in engine.py.

dafdeee41c (core) Optimize overly-cautious column replacing
Summary:
Replacing a column leads to an unnecessary recalculation, and was happening on
every schema change. This is particularly noticeble for large docs, especially
for imports when each column's addition is a schema change in itself, so
recalculation of summary table groupings were happening many times.

Test Plan: Existing tests should pass. No tests yet for avoiding recalculation, but would be nice!

7f1f8fc9e6 (core) Linking summary tables grouped by list columns
Summary:
Prefix keys of `LinkingState.filterColValues` with `_contains:` when the source column is a ChoiceList or ReferenceList.

This is parsed out to make a boolean `isContainsFilter` which is kept in each value of `QueryRefs.filterTuples` (previously `filterPairs`).

Then when converting back in `convertQueryFromRefs` we construct `Query.contains: {[colId: string]: boolean}`.

Finally `getFilterFunc` uses `Query.contains` to decide what kind of filtering to do.

This is not pretty, but the existing code is already very complex and it was hard to find something that wouldn't require touching loads of code just to make things compile.

Test Plan: Added a new nbrowser test and fixture, tests that selecting a source table by summary tables grouped by a choicelist column, non-list column, and both all filter the correct data.

bb8cb2593d (core) support python3 in grist-core, and running engine via docker and/or gvisor
Summary:
 * Moves essential plugins to grist-core, so that basic imports (e.g. csv) work.
 * Adds support for a `GRIST_SANDBOX_FLAVOR` flag that can systematically override how the data engine is run.
   - `GRIST_SANDBOX_FLAVOR=pynbox` is "classic" nacl-based sandbox.
   - `GRIST_SANDBOX_FLAVOR=docker` runs engines in individual docker containers. It requires an image specified in `sandbox/docker` (alternative images can be named with `GRIST_SANDBOX` flag - need to contain python and engine requirements). It is a simple reference implementation for sandboxing.
   - `GRIST_SANDBOX_FLAVOR=unsandboxed` runs whatever local version of python is specified by a `GRIST_SANDBOX` flag directly, with no sandboxing. Engine requirements must be installed, so an absolute path to a python executable in a virtualenv is easiest to manage.
   - `GRIST_SANDBOX_FLAVOR=gvisor` runs the data engine via gvisor's runsc. Experimental, with implementation not included in grist-core. Since gvisor runs on Linux only, this flavor supports wrapping the sandboxes in a single shared docker container.
 * Tweaks some recent express query parameter code to work in grist-core, which has a slightly different version of express (smoke test doesn't catch this since in Jenkins core is built within a workspace that has node_modules, and wires get crossed - in a dev environment the problem on master can be seen by doing `buildtools/build_core.sh /tmp/any_path_outside_grist`).

The new sandbox options do not have tests yet, nor does this they change the behavior of grist servers today. They are there to clean up and consolidate a collection of patches I've been using that were getting cumbersome, and make it easier to run experiments.

I haven't looked closely at imports beyond core.

Summary:
This switches to using stdin/stdout for RPC calls to the sandbox, rather than specially allocated side channels. Plain text error information remains on stderr.

The motivation for the change is to simplify use of sandboxes, some of which support extra file descriptors and some of which don't.

The new style of communication is made the default, but I'm not committed to this, just that it be easy to switch to if needed. It is possible I'll need to switch the communication method again in the near future.

One reason not to make this default would be windows support, which is likely broken since stdin/stdout are by default in text mode.

Run JS with a value for SANDBOX_BUFFERS_DIR, then run test_replay in python with the same value to replay just the python code.

See test_replay.py for more info.

Test Plan:
Record some data, e.g. `SANDBOX_BUFFERS_DIR=manual npm start` or `SANDBOX_BUFFERS_DIR=server ./test/testrun.sh server`.

Then run `SANDBOX_BUFFERS_DIR=server python -m unittest test_replay` from within `core/sandbox/grist` to replay the input from the JS.

Sample of the output will look like this:

```
Checking /tmp/sandbox_buffers/server/2021-06-16T15:13:59.958Z
True
Checking /tmp/sandbox_buffers/server/2021-06-16T15:16:37.170Z
True
Checking /tmp/sandbox_buffers/server/2021-06-16T15:14:22.378Z
True
```

b537539b73 (core) Implement UI for trigger formulas.
Summary:
- Implement UI with "Apply to new records" and "Apply on record changes"
  checkboxes, and options for selecting which changes to recalculate on.
- For consistency, always represent empty RefList as None
- Fix up generated SchemaTypes to remember that values are encoded.

Included test cases for the main planned use cases:
- Auto-filled UUID column
- Data cleaning
- NOW() formula for record's last-updated timestamp.
- Updates that depend on other columns.

Test Plan: Added a browser test.

Dmitry S
a56714e1ab (core) Implement trigger formulas (generalizing default formulas)
Summary:
Trigger formulas can be calculated for new records, or for new records and
updates to certain fields, or all fields. They do not recalculate on open,
and they MAY be set directly by the user, including for data-cleaning.

- Column metadata now includes recalcWhen and recalcDeps fields.
- Trigger formulas are NOT recalculated on open or on schema changes.
- When recalcWhen is "never", formula isn't calculated even for new records.
- When recalcWhen is "allupdates", formula is calculated for new records and
  any manual (non-formula) updates to the record.
- When recalcWhen is "", formula is calculated for new records, and changes to
  recalcDeps fields (which may be formula fields or column itself).
- A column whose recalcDeps includes itself is a "data-cleaning" column; a
  value set by the user will still trigger the formula.
- All trigger-formulas receive a "value" argument (to support the case above).

Small changes
- Update RefLists (used for recalcDeps) when target rows are deleted.
- Add RecordList.__contains__ (for `rec in refList` or `id in refList` checks)
- Clarify that Calculate action has replaced load_done() in practice,
  and use it in tests too, to better match reality.

Left for later:
- UI for setting recalcWhen / recalcDeps.
- Implementation of actions such as "Recalculate for all cells".
- Allowing trigger-formulas access to the current user's info.

Test Plan: Added a comprehensive python-side test for various trigger combinations

8a940676e9 (core) Generic tools for recording pycalls, deterministic mode.
Summary:
Replaces https://phab.getgrist.com/D2854

Refactoring of NSandbox:
- Simplify arguments to NSandbox.spawn. Only half the arguments were used depending on the flavour, adding a layer of confusion.
- Ensure the same environment variables are passed to both flavours of sandbox
- Simplify passing down environment variables.

Implement deterministic mode with libfaketime and a seeded random instance.
- Include static prebuilt libfaketime.so.1, may need another solution in future for other platforms.

Recording pycalls:
- Add script recordDocumentPyCalls.js to open a single document outside of tests.
- Refactor out recordPyCalls.ts to support various uses.
- Add afterEach hook to save all pycalls from server tests under $PYCALLS_DIR
- Make docTools usable without mocha.
- Add useLocalDoc and loadLocalDoc for loading non-fixture documents

Test Plan:
Made a document with formulas NOW() and UUID()
Compare two document openings in normal mode:

    diff <(test/recordDocumentPyCalls.js samples/d4W6NrzCMNVSVD6nWgNrGC.grist /dev/stdout) \
         <(test/recordDocumentPyCalls.js samples/d4W6NrzCMNVSVD6nWgNrGC.grist /dev/stdout)

Output:

    <                 1623407499.58132,

`export DETERMINISTIC_MODE=1` and repeat. diff is empty!
