7a6d726daa (core) Change datepicker in DateEditor to use moment format, show AltText in DateEditor
Summary:
- Rather than translate from moment format to that of bootstrap-datepicker, use
  the customization methods to format datepicker dates using moment directly.
- Fix issue with parseDate() when format includes tokens like Mo or Do
- Fix issue in parseDateTime() that could produce an off-by-one error in date
  depending on local timezone.
- When opening DateEditor, show AltText value if present.

- Add crossorigin=anonymous to scripts that were missing it (including
  bootstrap-datepicker), to ensure that errors from them are reported properly
  rather than as 'Script error.'

Test Plan:
Added test cases to parseDate() test for low-level fixes; added a
browser test for the fixed DateEditor behavior.

116fb15eda (core) Move most of the reference parsing code into common so that the server can use it
Summary: Refactoring in preparation for parsing strings from the API. The plan is that the API code will only need to do a server-side version of the code in ViewFieldRec.valueParser (minus ReferenceUtils) which is quite minimal.

0d460ac2d4 (core) Parsing pasted ChoiceLists
Summary:
Added ChoiceListParser capable of parsing JSON, CSVs, and other strings containing user-configured choices (e.g. separated by spaces)

I got a little carried away here. It works, and I can't think of any bugs, but it's complicated enough that there could be hidden edge cases or difficulties maintaining it in the future. The advantage of the current method is that it should work well for ambiguous or poorly formatted inputs, e.g. choices separated only by spaces or choices containing commas which are not escaped/quoted properly. The code can be vastly simplified if we don't try to support that and require that users paste proper JSON or CSVs.

Test Plan: Added a new file test/common/ChoiceListParser.ts with pure unit tests. Waiting for approval of the overall approach before adding to the nbrowser CopyPaste test.

Summary:
BulkAddRecord when finishing imports of nested JSON was throwing
an error due to unchecked access of referencing tables. This adds
a guard to prepare_new_values to handle such cases.

Imports happened to cause this to occur because the order that
imported tables are created/populated isn't aware of references
between tables, so it's possible for a reference column to
exist (momentarily) without a valid reference to another table.
These references are currently fixed after all imported tables are
created/populated.

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.

db34e1a6d9 (core) tweak throttling to work for gvisor/runsc
Summary:
Grist has, up to now, used a throttling mechanism that allows a sandbox free rein until it starts using above some threshold percentage of a cpu for some time - at that point, we start sending STOP and CONT signals on a duty cycle, with longer and longer STOPped periods until cpu usage is at a threshold. The general idea is to do short jobs quickly, while throttling long jobs (thus unfortunately making them even longer) in order to continue doing other short jobs quickly.

The runsc sandbox is not a single process, there are in fact 5 per sandbox in our setup. Runsc can work with kvm or ptrace. Kvm is not available to us, so we use ptrace. With ptrace, there is one process that is the appropriate one to duty cycle, and another that needs to receive a signal in order to yield. This diff adds the necessary machinery.

This is a conservative change, where I stick with our existing throttling mechanism and adapt it to the new sandbox. It would be reasonable to consider switching throttling. There's a lot the OS allows. We can set a quota for how much cpu a process can use within a given period, for example. However the overall behavior with that would be quite different to what we have, so feels like this would need more discussion.

The implementation contains use of a linux utility `pgrep` since portability is not important (runsc is only available on linux) and there's no node api for enumerating children of a process.

The diff contains some tweaks to `buildtools/contain.sh` to streamline experimenting with Grist and runsc on a mac. It is important for throttling that node and the sandbox processes are in the same process name space, if docker is in between them then some extra machinery is needed (a proxy throttler and a way to communicate with it) which I chose not to implement.

Test Plan: added test; a lot of manual testing
