Summary:
- `lookupRecords()` now allows efficient search in sorted results, with
the syntax `lookupRecords(..., order_by="-Date").find.le($Date)`. This will find the record with the nearest date that's <= `$Date`.
- The `find.*` methods are `le`, `lt`, `ge`, `gt`, and `eq`. All have O(log N) performance.
- `PREVIOUS(rec, group_by=..., order_by=...)` finds the previous record to rec, according to `group_by` / `order_by`, in amortized O(log N) time. For example, `PREVIOUS(rec, group_by="Account", order_by="Date")`.
- `PREVIOUS(rec, order_by=None)` finds the previous record in the full table, sorted by the `manualSort` column, to match the order visible in the unsorted table.
- `NEXT(...)` is just like `PREVIOUS(...)` but finds the next record.
- `RANK(rec, group_by=..., order_by=..., order="asc")` returns the rank of the record within the group, starting with 1. Order can be `"asc"` (default) or `"desc"`.
- The `order_by` argument in `lookupRecords`, and the new functions now supports tuples, as well as the "-" prefix to reverse order, e.g. `("Category", "-Date")`.
- New functions are only available in Python3, for a minor reason (to support keyword-only arguments for `group_by` and `order_by`) and also as a nudge to Python2 users to update.
- Includes fixes for several situations related to lookups that used to cause quadratic complexity.
Test Plan:
- New performance check that sorted lookups don't add quadratic complexity.
- Tests added for lookup find.* methods, and for PREVIOUS/NEXT/RANK.
- Tests added that renaming columns updates `order_by` and `group_by` arguments, and attributes on results (e.g. `PREVIOUS(...).ColId`) appropriately.
- Python3 tests can now produce verbose output when VERBOSE=1 and -v are given.

Summary:
- Replace logger module by the standard module 'logging'.
- When a log message from the sandbox includes newlines (e.g. for tracebacks),
keep those lines together in the Node log message.
Previously each line was a different message, making it difficult to view
tracebacks, particularly in prod where each line becomes a separate message
object.
- Fix assorted lint errors.
Test Plan: Added a test for the log-line splitting and escaping logic.

Summary:
Ensure that `lookupOne` (via `RecordSet.get_one`) pays attention to the `sort_by` parameter by picking the first of its sorted list of row IDs.
Allow specifying reverse sort order in `sort_by` by adding `"-"` before the column ID.

Summary:
Adds a method Table._num_rows using an empty lookup map column.
Adds a method Engine.count_rows which adds them all up.
Returns the count after applying user actions to be logged by ActiveDoc.
Test Plan: Added a unit test in Python. Tested log message manually.

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.

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.

Summary:
Added CONTAINS 'function' which can be used in lookups
Changed LookupMapColumn._row_key_map to use right=set so one row can have many keys when CONTAINS is used.
Use CONTAINS to implement group column in summary table, while helper column in source table can reference and create multiple rows in summary table, especially when summarising by ChoiceList columns.
Use itertools.product to generate all combinations of lookup keys and groupby values.

Summary:
Dealing with some things that bothered and sometimes confused me:
Make Table.Record[Set] provide the table argument automatically
Remove the classes from UserTable because they're not used anywhere and the Table/UserTable distinction is already confusing. They're not documented for users and they don't show up in autocomplete.
Remove RecordSet.Record because it was confusing me where that attribute was being set, but also this means .Record will work properly for users with columns named 'Record'.

Summary:
- Introduce a new SQLiteDB migration, which adds DB columns for formula columns
- Newly added columns have the special ['P'] (pending) value in them
(in order to show the usual "Loading..." on the first load that triggers the migration)
- Calculated values are added to .stored/.undo fields of user actions.
- Various changes made in the sandbox to include .stored/.undo in the right order.
- OnDemand tables ignore stored formula columns, replacing them with special SQL as before
- In particular, converting to OnDemand table leaves stale values in those
columns, we should maybe clean those out.
Some tweaks on the side:
- Allow overriding chai assertion truncateThreshold with CHAI_TRUNCATE_THRESHOLD
- Rebuild python automatically in watch mode
Test Plan: Fixed various tests, updated some fixtures. Many python tests that check actions needed adjustments because actions moved from .stored to .undo. Some checks added to catch situations previously only caught in browser tests.
