4ab096d179 (core) granular access control in the presence of schema changes
Summary:
 - Support schema changes in the presence of non-trivial ACL rules.
 - 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.
 - Force reloads if rules are changed.
 - Track rule changes within bundle, for clarity during schema changes - tableId and colId changes create a muddle otherwise.
 - Show or forbid pages dynamically depending on user's access to its sections. Logic unchanged, just no longer requires reload.
 - Fix calculation of pre-existing rows touched by a bundle, in the presence of schema changes.
 - Gray out acl page for non-owners.

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.

This adds back-end support for query parameters `aclAsUser_` and

5deac68315 (core) Update ACL resources/rules when tables/columns get renamed
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.
- Fix bug with rule positions.

Test Plan: Added a python and browser test for table/column renames.

3b3ae87ade (core) implement a safe mode for opening documents with rule problems
Summary:
Adds an "enter safe mode" option and explanation in modal that appears when a document fails to load, if user is owner. If "enter safe mode" is selected, document is reloaded on server in a special mode. Currently, the only difference is that if the acl rules fail to load, they are replaced with a fallback that grants full access to owners and no access to anyone else. An extra tag is shown to mark the document as safe mode, with an "x" for cancelling safe mode.

There are other ways a document could fail to load than just acl rules, so this is just a start.

Summary:
This adds any parameters in a document url whose key ends in '_'
into a `user.Link` object available in access control formulas
and in setting up characteristic tables.

This allows, for example, sending links to a document that contain

controlled part of the document (invoices for a specific customer
for example).

A `user.Origin` field is also added, set during rest api calls,
but is only tested manually at this point.  It could be elaborated
for embedding use-cases.

c67966775b (core) simplify document comparison code, and flesh out diff with local changes
Summary:
With recent changes to action history, we can now remove the temporary
`finalRowContent` field from change details, since all the information
we need is now in the ActionSummary.

We also now have more information about the state of the common ancestor,
which previously we could not get either from ActionSummary or from
`finalRowContent`. We take advantage of that to flesh out rendering
differences where there are some changes locally and some changes
remotely.

There's still a lot more to do, this is just one step.

I have added a link to the UI for viewing the comparison. I wouldn't
want to advertise that link until diffs are robust to name changes.

2a592d8b4d (core) Automatically finalize action bundles when unrelated actions/bundles come in.
Summary:
Type conversions and formula tranforms wait for the user and bundle multiple
actions. When an unrelated action is done (e.g. adding a page widget or a
column), we want to finalize the transform before applying it.

The approach turns out fairly complicated. There is an implicit queue of
bundles (which we don't let grow beyond 2, as that's too abnormal). Bundles may
be finalized by a user clicking something, or by an unrelated action/bundle, or
(as before) by transform DOM getting disposed.

- Updated RecordLayout to use bundleActions() helper
- Added support for nesting bundleActions inside another bundle (needed for
  setting visibleCol during type change)
- In an unrelated tweak, when in debug-log in ActiveDoc, use a short representation of result.

Test Plan: Added a unittest for action bundling during type transform

4febd90758 (core) Fix an insidious bug in RefCountMap, manifesting as JS errors some time after import.
Summary:
After an import from inside a document, one minute later, an important
QuerySet would get disposed, leaving the view section in a bad state,
and manifesting as JS errors on subsequent operations. (Might not
*always* happen because switching pages would prevent it from
manifesting, I think.)

Bad state that I've seen after transforms is probably explainable as
this bug, which is unrelated. Reproduction was hard because who knew one
had to wait a minute?!

Test Plan:
Added a unittest for the fix in QuerySet, and a browser test that
fails without the fix (JS errors, bad state), and passes with.

bd6a54e901 (core) mitigate csrf by requiring custom header for unsafe methods
Summary:
For methods other than `GET`, `HEAD`, and `OPTIONS`, allow cookie-based authentication only if a certain custom header is present.

Specifically, we check that `X-Requested-With` is set to `XMLHttpRequest`. This is somewhat arbitrary, but allows us to use https://expressjs.com/en/api.html#req.xhr.

A request send from a browser that sets a custom header will prompt a preflight check, giving us a chance to check if the origin is trusted.

This diff deals with getting the header in place. There will be more work to do after this:
 * Make sure that all important endpoints are checking origin.  Skimming code, /api endpoint check origin, and some but not all others.
 * Add tests spot-testing origin checks.
 * Check on cases that authenticate differently.
    - Check the websocket endpoint - it can be connected to from an arbitrary site; there is per-doc access control but probably better to lock it down more.
    - There may be old endpoints that authenticate based on knowledge of a client id rather than cookies.

Setting `style=light` removes side and top bars, as a first pass at a focused view of a single document page (this would benefit from refining).
