e492dfdb22 (core) add experimental support for python3 in staging
Summary:
This adds `runsc` and `python3` to the grist-server images. For deployments with GRIST_EXPERIMENTAL_PLUGINS=1 (dev + staging but not prod) a hack is added to use `python3` under `runsc` for documents with a special title (`activate-python3-magic` or similar).

This will simplify experiments on behavior of this configuration under realistic conditions.

Hopefully, before landing this, I'll be able to switch to storing a python flag in a document options cell being added by @georgegevoian in a parallel diff, since using the doc title is super hacky :-).

f9630b3aa4 (core) clean up a collection of small problems affecting grist-core
Summary:
 * Remove adjustSession hack, interfering with loading docs under saml.
 * Allow the anonymous user to receive an empty list of workspaces for
   the merged org.
 * Behave better on first page load when org is in path - this used to
   fail because of lack of cookie.  This is very visible in grist-core,
   as a failure to load localhost:8484 on first visit.
 * Mark cookie explicitly as SameSite=Lax to remove a warning in firefox.
 * Make errorPages available in grist-core.

This changes the default behavior of grist-core to now start off in
anonymous mode, with an explicit sign-in step available.  If SAML is not configured,
the sign-in operation will unconditionally sign the user in as a default
user, without any password check or other security.  The user email is
taken from GRIST_DEFAULT_EMAIL if set.  This is a significant change, but
makes anonymous mode available in grist-core (which is convenient
for testing) and makes behavior with and without SAML much more consistent.

Test Plan: updated test; manual (time to start adding grist-core tests though!)

54beaede84 (core) revive saml support and test against Auth0
Summary:

makes it work again, and tests it against Auth0 (now owned by Okta).

Logging in and out works.  The logged out state is confusing, and may
not be complete.  The "Add Account" menu item doesn't work.
But with this, an important part of self-hosting becomes easier.

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.

bb8cb2593d (core) support python3 in grist-core, and running engine via docker and/or gvisor
Summary:
 * Moves essential plugins to grist-core, so that basic imports (e.g. csv) work.
 * Adds support for a `GRIST_SANDBOX_FLAVOR` flag that can systematically override how the data engine is run.
   - `GRIST_SANDBOX_FLAVOR=pynbox` is "classic" nacl-based sandbox.
   - `GRIST_SANDBOX_FLAVOR=docker` runs engines in individual docker containers. It requires an image specified in `sandbox/docker` (alternative images can be named with `GRIST_SANDBOX` flag - need to contain python and engine requirements). It is a simple reference implementation for sandboxing.
   - `GRIST_SANDBOX_FLAVOR=unsandboxed` runs whatever local version of python is specified by a `GRIST_SANDBOX` flag directly, with no sandboxing. Engine requirements must be installed, so an absolute path to a python executable in a virtualenv is easiest to manage.
   - `GRIST_SANDBOX_FLAVOR=gvisor` runs the data engine via gvisor's runsc. Experimental, with implementation not included in grist-core. Since gvisor runs on Linux only, this flavor supports wrapping the sandboxes in a single shared docker container.
 * Tweaks some recent express query parameter code to work in grist-core, which has a slightly different version of express (smoke test doesn't catch this since in Jenkins core is built within a workspace that has node_modules, and wires get crossed - in a dev environment the problem on master can be seen by doing `buildtools/build_core.sh /tmp/any_path_outside_grist`).

The new sandbox options do not have tests yet, nor does this they change the behavior of grist servers today. They are there to clean up and consolidate a collection of patches I've been using that were getting cumbersome, and make it easier to run experiments.

I haven't looked closely at imports beyond core.

This makes it possible to set the type of a column to ReferenceList, but the UI is terrible

ReferenceList.ts is a mishmash of ChoiceList and Reference that sort of works but something about the CSS is clearly broken

ReferenceListEditor is just a text editor, you have to type in a JSON array of row IDs. Ignore the value that's present when you start editing. I can maybe try mashing together ReferenceEditor and ChoiceListEditor but it doesn't seem wise.

95cc2eb282 (core) read document as owner in pre-fork mode, if have sufficient access to it
Summary:
This tweaks pre-fork mode to make the user's experience a bit more seamless.
Pre-fork mode is where the user has opened a document with intent to
fork it, but actual forking (with allocation of a new document id)
is postponed until they make their first change.

The tweak makes the user an owner for granular access purposes, if
forking is permitted.  So data visible only to owners because of
access rules will be visible to them.  As always, any edits would
go to a separate new copy.

A remaining tricky corner is what to do about "View As" functionality
on forks.  Fork sharing cannot be controlled, so the "Users -> View As"
functionality isn't available.  Perhaps the "Users" button on a fork
could encourage doing a save-copy and inviting users, or offer some
dummy users?  In any case, this diff doesn't change anything with
that corner.

This adds a new landing page for cognito sign-up, intended for

Their email address is pre-filled and locked down, and sign-up

The page is very crude compared to hosted cognito - especially
in error reporting! - but having the address filled in more
than makes up for that.

The flow does not quite connect with the new billing signup.
I think we can do that through the regular "welcome" process,
which will list the user's team site.  When the user visits
that site, we could detect that we are on a site with no
domain set yet and for which the user is a billing manager,
and trigger a visit to the appropriate billing page.

8a940676e9 (core) Generic tools for recording pycalls, deterministic mode.
Summary:
Replaces https://phab.getgrist.com/D2854

Refactoring of NSandbox:
- Simplify arguments to NSandbox.spawn. Only half the arguments were used depending on the flavour, adding a layer of confusion.
- Ensure the same environment variables are passed to both flavours of sandbox
- Simplify passing down environment variables.

Implement deterministic mode with libfaketime and a seeded random instance.
- Include static prebuilt libfaketime.so.1, may need another solution in future for other platforms.

Recording pycalls:
- Add script recordDocumentPyCalls.js to open a single document outside of tests.
- Refactor out recordPyCalls.ts to support various uses.
- Add afterEach hook to save all pycalls from server tests under $PYCALLS_DIR
- Make docTools usable without mocha.
- Add useLocalDoc and loadLocalDoc for loading non-fixture documents

Test Plan:
Made a document with formulas NOW() and UUID()
Compare two document openings in normal mode:

    diff <(test/recordDocumentPyCalls.js samples/d4W6NrzCMNVSVD6nWgNrGC.grist /dev/stdout) \
         <(test/recordDocumentPyCalls.js samples/d4W6NrzCMNVSVD6nWgNrGC.grist /dev/stdout)

Output:

    <                 1623407499.58132,
    ---
    >                 1623407499.60376,

6f02987d10 (core) allow undos to be partial, if access control prohibits some part of them
Summary:
This is a somewhat experimental change, that will implement permitted parts of an undo if not all parts are permitted.  This is in preparation for trigger columns, where it may become common for a change in a record resulting in a change to an automatic change to another that the user cannot edit directly.  How to undo such an action is somewhat unclear.  One option is to undo the permitted parts, and then the triggers can rerun.

The general case is a bit of a can of worms, and feels adjacent to merging/rebasing etc.

Oh: it would probably be important in general to communicate to the user that an undo was partial, but this diff doesn't do that.  It would need some new plumbing.

29c2b35dcc (core) speed up a step in document deletion
Summary:
The `_repairWorkspaceGuests` method is slow for workspaces with large numbers of documents.  It makes a query that produces a lot of rows.  The query itself is tolerable, but TypeORM processing uses enough CPU to be a likely culprit in some production instability.  This diff splits the query into two pieces that are logically independent, but which when combined were resulting in the number of rows being the product of the two pieces.  Once split, there is also a where clause that can be applied to one of the pieces.

The purpose of the method is to add every user that a document within a workspace is shared with to a "guest" group of the workspace itself.  The design of "guest" groups is not ideal, but this diff leaves the design unchanged and is intended only to speed up operation.

Made some small tweaks to the timing of a flakey test, and temporarily recreated the `samples` directory removed in a previous diff (this is currently breaking tests badly on a fresh worker without a `samples` directory lying around)

d0d3d3d0c9 (core) discount indirect changes for access control purposes
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.

d8df2404c2 (core) return to using meaningful SQL types for columns
Summary:
Previously in {{D1053}} we switched to using BLOB as the "type" for all columns, to prevent SQLite from casting data unexpectedly.  This diff now returns to more meaningful types.  We apply marshalling to values when being placed in a column where a cast might occur, to inhibit such casting.

The benefit is that Grist documents become easier to interact with via regular database clients/libraries, which often rely on the column type more than a purely SQLite tool would.

On column type conversion, we run all blobs in the column through a decode/encode cycle so if they no longer need to be marshalled they revert to native type.  This could be optimized further, it is somewhat brute force.

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.

438f259687 (core) start reconciling forking with granular access
Summary:
This allows a fork to be made by a user if:
 * That user is an owner of the document being forked, or
 * That user has full read access to the document being forked.

The bulk of the diff is reorganization of how forking is done.  ActiveDoc.fork is now responsible for creating a fork, not just a docId/urlId for the fork. Since fork creation should not be limited to the doc worker hosting the trunk, a helper endpoint is added for placing the fork.

The change required sanitizing worker allocation a bit, and allowed session knowledge to be removed from HostedStorageManager.

Test Plan: Added test; existing tests pass.

68a682f876 (core) add housekeeping endpoints for cleaning doc snapshots+state
Summary:
This adds endpoints that allow the support user to remove unlisted
snapshots for a document, and to remove all action history for
a document.

This does increase what the support user can do, but not in a way
that would be particularly valuable to attack.  It would have some
destructive value, for removing history (removing unlisted
snapshots doesn't impact the user, by contrast).

This would simplify some maintenance operations.

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.

b1c4af4ee9 (core) correctly delete pruned document versions
Summary:
After switch to using an inventory file, old document versions were
not in fact being pruned.  This corrects that and adds a test
that fails with the previous implementation.

The pruner was operating correctly, but was being applied to an
inventory list rather than s3 directly - and the inventory list
did not pass through version removals to s3.

This fix will leave a stock of undeleted versions that can
be eliminated by an external script (there are alternatives
but that seems simplest overall).

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.

e5c24eb5ea (core) revamp user attribute handling
Summary:
This changes how user attributes are loaded.  They are now loaded
directly from sqlite, with per-session caching.  Optimizations
considered but not addressed yet are (1) adding indexes to user attribute
tables and (2) swapping in a thinner sqlite wrapper.

The main benefit of this diff is that changes to user attribute
tables now work.  Clients whose user attributes are not changed
see no effect; clients whose user attributes have changed have
their document reloaded.

For the purposes of testing, the diff includes a tweak to
GristWSConnection to be "sticky" to a specific user when reloading
(and support machinery on the server side to honor that).  Until
now, if a GristWSConnection reloads, it uses whatever the current
default user is in the cookie-based session, which can change.
This was complicating a test where multiple users were accessing
the same document via different clients with occasional document
reloads.

Code for updating when schema or rule changes happen is moved
around but not improved in any meaningful way in this diff.

Test Plan: existing tests pass; extended test

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.

131fbbdb92 (core) check row-level permissions on incoming actions
Summary:
This improves support for access control on document modifications.  It adds:

   * Checking of create/remove/update access for row-level changes.
   * Use of `newRec` variable in formulas.

It is now possible to have distinct clients with read+write access to different rows of the same table.

This is another incremental step.  There are deficiencies in actions that include schema changes, and many other lacunae. But the overall flow is taking shape.

Access control is done at the DocAction level, requiring the sandbox to process the UserActions, and then be reverted if the action proves unlawful.  This could be optimized away in many simple and important cases, but I'm not sure it is possible to avoid in general.
