7078922a65 (core) ensure randomness works when sandbox is cloned from a checkpoint
Summary:
This calls a new `initialize` method on the sandbox before we start
doing calculations with it, to make sure that `random.seed()` has
been called. Otherwise, if the sandbox is cloned from a checkpoint,
the seed will have been reset.

The `initialize` method includes the functionality previously done
by `set_doc_url` since it is also initialization/personalization and
this way we avoid introducing another round trip to the sandbox.

Test Plan: tested with grist-core configured to use gvisor

9fffb491f9 (core) External requests
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

Test Plan: Added Python and nbrowser tests.

437d30bd9f (core) Log number of rows in user tables in data engine
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.

e900f39da3 (core) Log statistics about table sizes
Summary:
Record numbers of rows, columns, cells, and bytes of marshalled data for most calls to table_data_from_db

Export new function get_table_stats in the sandbox, which gives the raw numbers and totals.

Get and log these stats in ActiveDoc right after loading tables, before Calculate, so they are logged even in case of errors.

Tweak logging about number of tables, especially number of on-demand tables, to not only show in debug logging.

Test Plan: Updated doc regression tests, that shows what the data looks like nicely.

dd0f1be117 (core) get all tests working under python3/gvisor
Summary:
This verifies that all existing tests are capable of running under python3/gvisor, and fixes the small issues that came up. It does not yet activate python3 tests on all diffs, only diffs that specifically request them.

 * Adds a suffix in test names and output directories for tests run with PYTHON_VERSION=3, so that results of the same test run with and without the flag can be aggregated cleanly.
 * Adds support for checkpointing to the gvisor sandbox adapter.
 * Prepares a checkpoint made after grist python code has loaded in the gvisor sandbox.
 * Changes how `DOC_URL` is passed to the sandbox, since it can no longer be passed in as an environment variable when using checkpoints.
 * Uses the checkpoint to speed up tests using the gvisor sandbox, otherwise a lot of tests need more time (especially on mac under docker).
 * Directs jenkins to run all tests with python2 and python3 when a new file `buildtools/changelogs/python.txt` is touched (this diff counts as touching that file).
 * Tweaks miscellaneous tests
   - some needed fixes exposed by slightly different timing
   - a small number actually give different results in py3 (removal of `u` prefixes).
   - some needed a little more time

The DOC_URL change is not the ultimate solution we want for DOC_URL. Eventually it should be a variable that gets updated, like the date perhaps. This is just a small pragmatic change to preserve existing behavior.

Tests are run mindlessly as py3, and for some tests it won't change anything (e.g. if they do not use NSandbox). Tests are not run in parallel, doubling overall test time.

Checkpoints could be useful in deployment, though this diff doesn't use them there.

The application of checkpoints doesn't check for other configuration like 3-versus-5-pipe that we don't actually use.

Python2 tests run using pynbox as always for now.

The diff got sufficiently bulky that I didn't tackle running py3 on "regular" diffs in it. My preference, given that most tests don't appear to stress the python side of things, would be to make a selection of the tests that do and a few wild cards, and run those tests on both pythons rather then all of them. For diffs making a significant python change, I'd propose touching buildtools/changelogs/python.txt for full tests. But this is a conversation in progress.

A total of 6886 tests ran on this diff.

Test Plan: this is a step in preparing tests for py3 transition

4d526da58f (core) Move file import plugins into core/sandbox/grist
Summary:
Move all the plugins python code into the main folder with the core code.

Register file importing functions in the same main.py entrypoint as the data engine.

Remove options relating to different entrypoints and code directories. The only remaining plugin-specific option in NSandbox is the import directory/mount, i.e. where files to be parsed are placed.

Test Plan: this

4222f1ed32 (core) communicate with sandbox via standard pipes
Summary:
This switches to using stdin/stdout for RPC calls to the sandbox, rather than specially allocated side channels. Plain text error information remains on stderr.

The motivation for the change is to simplify use of sandboxes, some of which support extra file descriptors and some of which don't.

The new style of communication is made the default, but I'm not committed to this, just that it be easy to switch to if needed. It is possible I'll need to switch the communication method again in the near future.

One reason not to make this default would be windows support, which is likely broken since stdin/stdout are by default in text mode.

Test Plan: existing tests pass

84ddbc448b (core) Add test_replay for easily replaying data sent to the sandbox purely within python
Summary:
Run JS with a value for SANDBOX_BUFFERS_DIR, then run test_replay in python with the same value to replay just the python code.

See test_replay.py for more info.

Test Plan:
Record some data, e.g. `SANDBOX_BUFFERS_DIR=manual npm start` or `SANDBOX_BUFFERS_DIR=server ./test/testrun.sh server`.

Then run `SANDBOX_BUFFERS_DIR=server python -m unittest test_replay` from within `core/sandbox/grist` to replay the input from the JS.

Sample of the output will look like this:

```
Checking /tmp/sandbox_buffers/server/2021-06-16T15:13:59.958Z
True
Checking /tmp/sandbox_buffers/server/2021-06-16T15:16:37.170Z

de35be6b0a (core) Checks that an ACL formula can be parsed, and prevent saving unparsable ACL rules.
Summary:
- Fix error-handling in bundleActions(), and wait for the full bundle to complete.
  (The omissions here were making it impossibly to react to errors from inside bundleActions())
- Catch problematic rules early enough to undo them, by trying out ruleCollection.update()
  on updated rules before the updates are applied.
- Added checkAclFormula() call to DocComm that checks parsing and compiling
  formula, and reports errors.
- In UI, prevent saving if any aclFormulas are invalid, or while waiting for the to get checked.

- Also fixed some lint errors

Test Plan: Added a test case of error reporting in ACL formulas.

5b2de988b5 (core) Perform migrations of Grist schema using only metadata tables when possible.
Summary:
Loading all user data to run a migration is risky (creates more than usual
memory pressure), and almost never needed (only one migration requires it).

This diff attempts to run migrations using only metadata (_grist_* tables),
but retries if the sandbox tells it that all data is needed.

The intent is for new migrations to avoid needing all data.

Test Plan: Added a somewhat contrived unittest.
