Summary:
Here's a series of badness that easily leads to a crash, in reverse order:
- Lodash's map() function interprets an object with a .length property as an array.
- Some very old code generated human-friendly descriptions of user actions,
applying map() to parts of them. It so happens that this generated description
isn't even used.
- If a user action is encountered with a sufficiently large length propery,
map() would exhaust the server memory.
Fixed by removing old unneeded code, and replacing some other occurrences of
lodash's map() with native equivalents.
Test Plan: Tested manually on a local reproduction of the issue.

Some edits to virtual tables (such as webhook lists) happen
via a route that was not yet handled. Actually Cyprien (the

because I didn't know what it was for :-). This brings back

Summary:
- Excel exports were awfully memory-inefficient, causing occasional docWorker
crashes. The fix is to use the "streaming writer" option of ExcelJS
https://github.com/exceljs/exceljs#streaming-xlsx-writercontents. (Empirically
on one example, max memory went down from 3G to 100M)
- It's also CPU intensive and synchronous, and can block node for tens of
seconds. The fix is to use a worker-thread. This diff uses "piscina" library
for a pool of threads.
- Additionally, adds ProcessMonitor that logs memory and cpu usage,
particularly when those change significantly.
- Also introduces request cancellation, so that a long download cancelled by
the user will cancel the work being done in the worker thread.
Test Plan:
Updated previous export tests; memory and CPU performance tested
manually by watching output of ProcessMonitor.
Difference visible in these log excerpts:
Before (total time to serve request 22 sec):
```
Telemetry processMonitor heapUsedMB=2187, heapTotalMB=2234, cpuAverage=1.13, intervalMs=17911
Telemetry processMonitor heapUsedMB=2188, heapTotalMB=2234, cpuAverage=0.66, intervalMs=5005
Telemetry processMonitor heapUsedMB=2188, heapTotalMB=2234, cpuAverage=0, intervalMs=5005
Telemetry processMonitor heapUsedMB=71, heapTotalMB=75, cpuAverage=0.13, intervalMs=5002
```
After (total time to server request 18 sec):
```
Telemetry processMonitor heapUsedMB=109, heapTotalMB=144, cpuAverage=0.5, intervalMs=5001
Telemetry processMonitor heapUsedMB=109, heapTotalMB=144, cpuAverage=1.39, intervalMs=5002
Telemetry processMonitor heapUsedMB=94, heapTotalMB=131, cpuAverage=1.13, intervalMs=5000
Telemetry processMonitor heapUsedMB=94, heapTotalMB=131, cpuAverage=1.35, intervalMs=5001
```
Note in "Before" that heapTotalMB goes up to 2GB in the first case, and "intervalMs" of 17 seconds indicates that node was unresponsive for that long. In the second case, heapTotalMB stays low, and the main thread remains responsive the whole time.

Summary:
for users who don't automatically have deep rights
to the document, provide them with attachment metadata only
for rows they have access to. This is a little tricky to
do efficiently. We provide attachment metadata when an
individual table is fetched, rather than on initial document
load, so we don't block that load on a full document scan.
We provide attachment metadata to a client when we see that
we are shipping rows mentioning particular attachments,
without making any effort to keep track of the metadata they
already have.

Summary:
First iteration for comments system for Grist.
- Comments are stored in a generic metatable `_grist_Cells`
- Each comment is connected to a particular cell (hence the generic name of the table)
- Access level works naturally for records stored in this table
-- User can add/read comments for cells he can see
-- User can't update/remove comments that he doesn't own, but he can delete them by removing cells (rows/columns)
-- Anonymous users can't see comments at all.
- Each comment can have replies (but replies can't have more replies)
Comments are hidden by default, they can be enabled by COMMENTS=true env variable.
Some things for follow-up
- Avatars, currently the user's profile image is not shown or retrieved from the server
- Virtual rendering for comments list in creator panel. Currently, there is a limit of 200 comments.

- Upgrades to build-related packages:
- Upgrade typescript, related libraries and typings.
- Upgrade webpack, eslint; add tsc-watch, node-dev, eslint_d.
- Build organization changes:
- Build webpack from original typescript, transpiling only; with errors still
reported by a background tsc watching process.
- Typescript-related changes:
- Reduce imports of AWS dependencies (very noticeable speedup)
- Avoid auto-loading global @types
- Client code is now built with isolatedModules flag (for safe transpilation)
- Use allowJs to avoid copying JS files manually.
- Linting changes
- Enhance Arcanist ESLintLinter to run before/after commands, and set up to use eslint_d
- Update eslint config, and include .eslintignore to avoid linting generated files.
- Include a bunch of eslint-prompted and eslint-generated fixes
- Add no-unused-expression rule to eslint, and fix a few warnings about it
- Other items:
- Refactor cssInput to avoid circular dependency
- Remove a bit of unused code, libraries, dependencies
Test Plan: No behavior changes, all existing tests pass. There are 30 tests fewer reported because `test_gpath.py` was removed (it's been unused for years)

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

Summary:
This implements row-level access control for outgoing messages, replacing the document reloading placeholder that was there before.
* Prior to broadcasting messages, GranularAccess is notified of actions+undo.
* While broadcasting messages to different sessions, if we find we need row level access control information, rows before and after the change are reconstructed.
* Messages are rewritten if rows that were previously forbidden are now allowed, and vice versa.
The diff is somewhat under-tested and under-optimized. Next step would be to implement row-level access control for incoming actions, which may result in some rejiggering of the code from this diff to avoid duplication of effort under some conditions.

Summary:
This simplifies writing custom widgets that access selected
data. To access the record at which the cursor is set, and
get any future changes to it as the cursor moves or data
changes, it suffices now to do:
```
grist.ready();
grist.onRecord(record => /* render */);
```
Similarly to access the set of selected records, and get any
changes, it suffices now to do:
```
grist.ready();
grist.onRecords(records => /* render */);
```
The `records` argument will be a list of objects, each of which
is a single record. This is distinct from the column-based
representation favored in Grist up ontil now. That remains
how methods like `fetchTable` or `fetchSelectedTable` represent
their results. In the future, methods named like `fetchRecords`
or `fetchSelectedRecords` could be added that return lists.
