1c89d08ea3 (core) Add a row to summary tables grouped by list column(s) corresponding to empty lists
Summary:
Adds some special handling to summary table and lookup logic:

- Source rows with empty choicelists/reflists get a corresponding summary row with an empty string/reference when grouping by that column, instead of excluding them from any group
- Adds a new `QueryOperation` 'empty' in the client which is used in `LinkingState`, `QuerySet`, and `recursiveMoveToCursorPos` to match empty lists in source tables against falsy values in linked summary tables.
- Adds a new parameter `match_empty` to the Python `CONTAINS` function so that regular formulas can implement the same behaviour as summary tables. See https://grist.slack.com/archives/C0234CPPXPA/p1654030490932119
- Uses the new `match_empty` argument in the formula generated for the `group` column when detaching a summary table.

Test Plan: Updated and extended Python and nbrowser tests of summary tables grouped by choicelists to test for new behaviour with empty lists.

c5ebd7db3d (core) Add PEEK() function to bypass circular dependencies
Summary:
Adds a Python function `PEEK()` for use in formulas which temporarily sets a new attribute `Engine._peeking` which disables the `_use_node` method, preventing dependency tracking and allowing the given expression to use outdated values. This allows circumventing circular reference errors. It's particularly meant for trigger formulas although it works in normal formulas as well. The expression is wrapped in a `lambda` by `codebuilder` for lazy evaluation.

Discussion: https://grist.slack.com/archives/C0234CPPXPA/p1653571024031359

Test Plan: Added a Python unit test for circular trigger formulas using PEEK.

8ee23f5344 (core) Mark column changing actions as indirect when adding data to empty column
Summary:
Fixing https://gristlabs.getgrist.com/doc/check-ins/p/12#a1.s19.r1045.c19 :

> 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

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

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.

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.

bf271c822b (core) Copy column type and options when pasting into an empty column
Summary:
Adds a `data-grist-col-ref` attribute to the copied HTML, then uses that when pasting to look up the source column and retrieve info about it. Copies the info into the target column if:

- The document is the same (the docId hash matches)
- The source column still exists and has the same type as when copied
- The source type isn't Text, because in that case it's nice if type guessing still happens
- The target column is empty, meaning it has type Any (we check earlier that it's not a formula column)

The info copied is the type, widgetOptions, and reference column settings (visible and display columns) but not conditional formatting.

The changes are mostly in a function `parsePasteForView` which is based on `BaseView._parsePasteForView` but ported to TypeScript in a new file `BaseView2.ts`.

Added a useraction `MaybeCopyDisplayFormula` exposing an existing Python function `maybe_copy_display_formula` because the target column needs a slightly different display formula.

Test Plan: Added a new nbrowser test file and fixture doc.

d154b9afa7 (core) Make lookups depend on all rows
Summary:
This is a fix for a bug discussed in https://grist.slack.com/archives/C069RUP71/p1645138610722889

I still haven't completely wrapped my head around it or figured out how to make a simple reproducible example, but the problem seems to be that a lookup can happen before the column(s) being looked up (the summary helper column in this case) have been computed fully (I think it got interrupted halfway by an OrderError). `do_lookup` would check via `engine._use_node` that the row IDs it found had all been computed already, but there might still be other rows that hadn't been computed yet and would also have values matching the lookup key, so it missed those.

This diff instead calls `_use_node` with no `row_ids` argument, which should ensure that all rows have already been computed.

At first I was worried about how this would affect performance, which led me down an optimisation rabbit hole, hence a bit of unrelated cleanup here and also https://phab.getgrist.com/D3310 . But it doesn't seem to be a problem, and IIUC it should actually make things better, although this code is pretty confusing.

Summary:
This is an attempt to optimise Engine._use_node. It doesn't seem to actually improve overall performance significantly, but it shouldn't make it worse, and I think it's an improvement to the code.

It turns out that there's no need to track a stack of compute frames any more. The only time we get close to nested evaluation, we set allow_evaluation=False to prevent it actually happening. So there's only one 'frame' during actual evaluation, which means we can get rid of the concept of frames entirely. This allows simplifying the code and letting the computer do less work in general.

321019217d (core) Lossless imports
Summary:
- Removed string parsing and some type guessing code from parse_data.py. That logic is now implicitly done by ValueGuesser by leaving the initial column type as Any. parse_data.py mostly comes into play when importing files (e.g. Excel) containing values that already have types, i.e. numbers and dates.
- 0s and 1s are treated as numbers instead of booleans to keep imports lossless.
- Removed dateguess.py and test_dateguess.py.
- Changed what `guessDateFormat` does when multiple date formats work equally well for the given data, in order to be consistent with the old dateguess.py.
- Columns containing numbers are now always imported as Numeric, never Int.
- Removed `NullIfEmptyParser` because it was interfering with the new system. Its purpose was to avoid pointlessly changing a column from Any to Text when no actual data was inserted. A different solution to that problem was already added to `_ensure_column_accepts_data` in the data engine in a recent related diff.

Test Plan:
- Added 2 `nbrowser/Importer2` tests.
- Updated various existing tests.
- Extended testing of `guessDateFormat`. Added `guessDateFormats` to show how ambiguous dates are handled internally.

accd640078 (core) add a user.SessionID value for trigger formulas and granular access rules
Summary:
This makes a `user.SessionID` value available in information about the user, for use with trigger formulas and granular access rules. The ID should be constant within a browser session for anonymous user. For logged in users it simply reflects their user id.

This ID makes it possible to write access rules and trigger formulas that allow different anonymous users to create, view, and edit their own records in a document.

For example, you could have a brain-storming document for puns, and allow anyone to add to it (without logging in), letting people edit their own records, but not showing the records to others until they are approved by a moderator. Without something like this, we could only let anonymous people add one field of a record, and not have a secure way to let them edit that field or others in the same record.

Also adds a `user.IsLoggedIn` flag in passing.

Test Plan: Added a test, updated tests. The test added is a mini-moderation doc, don't use it for real because it allows users to edit their entries after a moderator has approved them.

0de0cb0f4a (core) Add PUT /records DocApi endpoint to AddOrUpdate records
Summary:
As designed in https://grist.quip.com/fZSrAnJKgO5j/Add-or-Update-Records-API

Current `POST /records` adds records, and `PATCH /records` updates them by row ID. This adds `PUT /records` to 'upsert' records, applying the AddOrUpdate user action. PUT was chosen because it's idempotent. Using a separate method (instead of inferring based on the request body) also cleanly separates validation, documentation, etc.

The name `require` for the new property was suggested by Paul because `where` isn't very clear when adding records.

f024aaaf5d (core) Fix some bugs with ChoiceList in summary tables, and evaluation of lookups.
Summary:
Addresses several issues:
- Error 'Cannot modify summary group-by column' when changing Text ->
  ChoiceList in the presence of summary tables.
- Error 'ModifyColumn in unexpected position' when changing ChoiceList -> Text
  in the presence of summary tables.
- Double-evaluation of trigger formulas in some cases.

Fixes include:
- Fixed verification that summary group-by columns match the underlying ones,
  and added comments to explain.
- Avoid updating non-metadata lookups after each doc-action (early lookups
  generated extra actions to populate summary tables, causing the 'ModifyColumn
  in unexpected position' bug)
- When updating formulas, do update lookups first.
- Made a client-side tweak to avoid a JS error in case of some undos.

Solution to reduce lookups is based on https://phab.getgrist.com/D3069?vs=on&id=12445,
and tests for double-evaluation of trigger formulas are taken from there.

Add a new test case to protect against bugs caused by incorrect order of
evaluating #lookup columns.

Enhanced ChoiceList browser test to check a conversion scenario in the presence
of summary tables, previously triggering bugs.

Test Plan: Various tests added or enhanced.

ecb30eebb8 (core) Parsing multiple values in reflists, parsing refs without table data in client
Summary:
Added a new object type code `l` (for lookup) which can be used in user actions as a temporary cell value in ref[list] columns and is immediately converted to a row ID in the data engine. The value contains the original raw string (to be used as alt text), the column ID to lookup (typically the visible column) and one or more values to lookup.

For reflists, valueParser now tries parsing the string first as JSON, then as a CSV row, and applies the visible column parsed to each item.

Both ref and reflists columns no longer format the parsed value when there's no matching reference, the original unparsed string is used as alttext instead.

dd0f1be117 (core) get all tests working under python3/gvisor
Summary:
This verifies that all existing tests are capable of running under python3/gvisor, and fixes the small issues that came up. It does not yet activate python3 tests on all diffs, only diffs that specifically request them.

 * Adds a suffix in test names and output directories for tests run with PYTHON_VERSION=3, so that results of the same test run with and without the flag can be aggregated cleanly.
 * Adds support for checkpointing to the gvisor sandbox adapter.
 * Prepares a checkpoint made after grist python code has loaded in the gvisor sandbox.
 * Changes how `DOC_URL` is passed to the sandbox, since it can no longer be passed in as an environment variable when using checkpoints.
 * Uses the checkpoint to speed up tests using the gvisor sandbox, otherwise a lot of tests need more time (especially on mac under docker).
 * Directs jenkins to run all tests with python2 and python3 when a new file `buildtools/changelogs/python.txt` is touched (this diff counts as touching that file).
 * Tweaks miscellaneous tests
   - some needed fixes exposed by slightly different timing
   - a small number actually give different results in py3 (removal of `u` prefixes).
   - some needed a little more time

The DOC_URL change is not the ultimate solution we want for DOC_URL. Eventually it should be a variable that gets updated, like the date perhaps. This is just a small pragmatic change to preserve existing behavior.

Tests are run mindlessly as py3, and for some tests it won't change anything (e.g. if they do not use NSandbox). Tests are not run in parallel, doubling overall test time.

Checkpoints could be useful in deployment, though this diff doesn't use them there.

The application of checkpoints doesn't check for other configuration like 3-versus-5-pipe that we don't actually use.

Python2 tests run using pynbox as always for now.

The diff got sufficiently bulky that I didn't tackle running py3 on "regular" diffs in it. My preference, given that most tests don't appear to stress the python side of things, would be to make a selection of the tests that do and a few wild cards, and run those tests on both pythons rather then all of them. For diffs making a significant python change, I'd propose touching buildtools/changelogs/python.txt for full tests. But this is a conversation in progress.

A total of 6886 tests ran on this diff.

Test Plan: this is a step in preparing tests for py3 transition

- 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.

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).

Test Plan: added tests

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.

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.

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.

Summary:
This diff discounts indirect changes for access control purposes.  A UserAction that updates a cell A, which in turn causes changes in other dependent cells, will be considered a change to cell A for access control purposes.

The `engine.apply_user_actions` method now returns a `direct` array, with a boolean for each `stored` action, set to `true` if the action is attributed to the user or `false` if it is attributed to the engine.  `GranularAccess` ignores actions attributed to the engine when checking for edit rights.

Subtleties:
 * Removal of references to a removed row are considered direct changes.
 * Doesn't play well with undos as yet.  An action that indirectly modifies a cell the user doesn't have rights to may succeed, but it will not be reversible.

0c5f7cf0a7 (core) add SELF_HYPERLINK() function for generating links to the current document
Summary:
 * Adds a `SELF_HYPERLINK()` python function, with optional keyword arguments to set a label, the page, and link parameters.
 * Adds a `UUID()` python function, since using python's uuid.uuidv4 hits a problem accessing /dev/urandom in the sandbox.  UUID makes no particular quality claims since it doesn't use an audited implementation.  A difficult to guess code is convenient for some use cases that `SELF_HYPERLINK()` enables.

The canonical URL for a document is mutable, but older versions generally forward.  So for implementation simplicity the document url is passed it on sandbox creation and remains fixed throughout the lifetime of the sandbox.  This could and should be improved in future.

The URL is passed into the sandbox as a `DOC_URL` environment variable.

The code for creating the URL is factored out of `Notifier.ts`. Since the url is a function of the organization as well as the document, some rejiggering is needed to make that information available to DocManager.

On document imports, the new document is registered in the database slightly earlier now, in order to keep the procedure for constructing the URL in different starting conditions more homogeneous.

Summary:

 - Fix update of `aclFormulaParsed` when updating formulas automatically after schema change.
 - Filter private metadata in broadcasts, not just fetches.  Censorship method is unchanged, just refactored.
 - Allow only owners to change ACL rules.

6af811f7ab (core) give more detailed reasons for access denied when memos are present
Summary:
With this change, if a comment is added to an ACL formula, then that comment will be offered to the user if access is denied and that rule could potentially have granted access.

The code is factored so that when access is permitted, or when partially visible tables are being filtered, there is little overhead. Comments are gathered only when an explicit denial of access.

ec023a3ba6 (core) Fix another cause of inconsistency that can be triggered by bad DocActions.
Summary:
An incorrect DocAction (as possible from an Undo of a non-last action)

14cdd47675 (core) When checking for metadata consistency, check for stray column records too
Summary:
Currently, an undo of a non-last action can leave the doc in an inconsistent
state. For example, it may remove a table, but fail to remove all columns of
it from metadata. We normally check that schema corresponds to metadata, but
stray columns were not visible to this check, and instead caused later table
additions to fail.

This diff fixes the check to fail the action that causes stray columns, and
to restore the doc to a consistent state.

Note that this only handles schema-metadata inconsistencies, but an undo of a
non-last action can easily create other surprises.

Test Plan: Added a test case that triggered inconsistency before, and now triggers a failed undo.

Summary:
- Placed rule-updating functions in acl.py.
- Reset UI when rules update externally, or alert the user to reset if there
  are pending local changes.
- Removed some unused and distracting bits from client-side DocModel.

A few improvements related to poor error handling:
- In case of missing DocActions (tickled by broken ACL rule handling), don't
  add to confusion by attempting to process bad actions
- In case of missing attributes in ACL formulas, return undefined rather than
  fail; the latter creates more problems.
- In case in invalid rules, fail rather than skip; this feels more correct now
  that we have error checking and recovery option, and helps avoid invalid rules.
- Prevent saving invalid rules with an empty ACL formula.

45d2d5f897 (core) back-end support for tables that are accessible only by owners
Summary:
This makes it possible to serve a table or tables only to owners.

 * The _grist_ACLResources table is abused (temporarily) such that rows of the form `{colId: '~o', tableId}` are interpreted as meaning that `tableId` is private to owners.
 * Many websocket and api endpoints are updated to preserve the privacy of these tables.
 * In a document where some tables are private, a lot of capabilities are turned off for non-owners to avoid leaking info indirectly.
 * The client is tweaked minimally, to show '-' where a page with some private material would otherwise go.

No attempt is made to protect data from private tables pulled into non-private tables via formulas.

There are some known leaks remaining:
 * Changes to the schema of private tables are still broadcast to all clients (fixable).
 * Non-owner may be able to access snapshots or make forks or use other corners of API (fixable).
 * Changing name of table makes it public, since tableId in ACLResource is not updated (fixable).

Security will require some work, the attack surface is large.
