(core) Initial webhooks implementation Summary: See https://grist.quip.com/VKd3ASF99ezD/Outgoing-Webhooks - 2 new DocApi endpoints: _subscribe and _unsubscribe, not meant to be user friendly or publicly documented. _unsubscribe should be given the response from _subscribe in the body, e.g: ``` $ curl -X POST -H "Authorization: Bearer 8fd4dc59ecb05ab29ae5a183c03101319b8e6ca9" "http://localhost:8080/api/docs/6WYa23FqWxGNe3AR6DLjCJ/tables/Table2/_subscribe" -H "Content-type: application/json" -d '{"url": "https://webhook.site/a916b526-8afc-46e6-aa8f-a625d0d83ec3", "eventTypes": ["add"], "isReadyColumn": "C"}' {"unsubscribeKey":"3246f158-55b5-4fc7-baa5-093b75ffa86c","triggerId":2,"webhookId":"853b4bfa-9d39-4639-aa33-7d45354903c0"} $ curl -X POST -H "Authorization: Bearer 8fd4dc59ecb05ab29ae5a183c03101319b8e6ca9" "http://localhost:8080/api/docs/6WYa23FqWxGNe3AR6DLjCJ/tables/Table2/_unsubscribe" -H "Content-type: application/json" -d '{"unsubscribeKey":"3246f158-55b5-4fc7-baa5-093b75ffa86c","triggerId":2,"webhookId":"853b4bfa-9d39-4639-aa33-7d45354903c0"}' {"success":true} ``` - New DB entity Secret to hold the webhook URL and unsubscribe key - New document metatable _grist_Triggers subscribes to table changes and points to a secret to use for a webhook - New file Triggers.ts processes action summaries and uses the two new tables to send webhooks. - Also went on a bit of a diversion and made a typesafe subclass of TableData for metatables. I think this is essentially good enough for a first diff, to keep the diffs manageable and to talk about the overall structure. Future diffs can add tests and more robustness using redis etc. After this diff I can also start building the Zapier integration privately. Test Plan: Tested manually: see curl commands in summary for an example. Payloads can be seen in https://webhook.site/#!/a916b526-8afc-46e6-aa8f-a625d0d83ec3/0b9fe335-33f7-49fe-b90b-2db5ba53382d/1 .

The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case. I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error. I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end.

I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error. I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end.

(core) support GRIST_WORKER_GROUP to place worker into an exclusive group Summary: In an emergency, we may want to serve certain documents with "old" workers as we fix problems. This diff adds some support for that. * Creates duplicate task definitions and services for staging and production doc workers (called grist-docs-staging2 and grist-docs-prod2), pulling from distinct docker tags (staging2 and prod2). The services are set to have zero workers until we need them. * These new workers are started with a new env variable `GRIST_WORKER_GROUP` set to `secondary`. * The `GRIST_WORKER_GROUP` variable, if set, makes the worker available to documents in the named group, and only that group. * An unauthenticated `/assign` endpoint is added to documents which, when POSTed to, checks that the doc is served by a worker in the desired group for that doc (as set manually in redis), and if not frees the doc up for reassignment. This makes it possible to move individual docs between workers without redeployments. The bash scripts added are a record of how the task definitions + services were created. The services could just have been copied manually, but the task definitions will need to be updated whenever the definitions for the main doc workers are updated, so it is worth scripting that. For example, if a certain document were to fail on a new deployment of Grist, but rolling back the full deployment wasn't practical: * Set prod2 tag in docker to desired codebase for that document * Set desired_count for grist-docs-prod2 service to non-zero * Set doc-<docid>-group for that doc in redis to secondary * Hit /api/docs/<docid>/assign to move the doc to grist-docs-prod2 (If the document needs to be reverted to a previous snapshot, that currently would need doing manually - could be made simpler, but not in scope of this diff).

(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.

(core) Adds a UI panel for managing webhooks Summary: This adds a UI panel for managing webhooks. Work started by Cyprien Pindat. You can find the UI on a document's settings page. Main changes relative to Cyprien's demo: * Changed behavior of virtual table to be more consistent with the rest of Grist, by factoring out part of the implementation of on-demand tables. * Cell values that would create an error can now be denied and reverted (as for the rest of Grist). * Changes made by other users are integrated in a sane way. * Basic undo/redo support is added using the regular undo/redo stack. * The table list in the drop-down is now updated if schema changes. * Added a notification from back-end when webhook status is updated so constant polling isn't needed to support multi-user operation. * Factored out webhook specific logic from general virtual table support. * Made a bunch of fixes to various broken behavior. * Added tests. The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case. I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error. I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end. Sneaky. Contains a migration, so needs an extra reviewer for that. Test Plan: added tests Reviewers: jarek, dsagal Reviewed By: jarek, dsagal Differential Revision: https://phab.getgrist.com/D3856

Main changes relative to Cyprien's demo: * Changed behavior of virtual table to be more consistent with the rest of Grist, by factoring out part of the implementation of on-demand tables. * Cell values that would create an error can now be denied and reverted (as for the rest of Grist). * Changes made by other users are integrated in a sane way. * Basic undo/redo support is added using the regular undo/redo stack. * The table list in the drop-down is now updated if schema changes. * Added a notification from back-end when webhook status is updated so constant polling isn't needed to support multi-user operation. * Factored out webhook specific logic from general virtual table support. * Made a bunch of fixes to various broken behavior. * Added tests. The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case. I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error. I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end.

Main changes relative to Cyprien's demo: * Changed behavior of virtual table to be more consistent with the rest of Grist, by factoring out part of the implementation of on-demand tables. * Cell values that would create an error can now be denied and reverted (as for the rest of Grist). * Changes made by other users are integrated in a sane way. * Basic undo/redo support is added using the regular undo/redo stack. * The table list in the drop-down is now updated if schema changes. * Added a notification from back-end when webhook status is updated so constant polling isn't needed to support multi-user operation. * Factored out webhook specific logic from general virtual table support. * Made a bunch of fixes to various broken behavior. * Added tests. The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case. I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error. I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end. Sneaky. Contains a migration, so needs an extra reviewer for that. Test Plan: added tests Reviewers: jarek, dsagal Reviewed By: jarek, dsagal Differential Revision: https://phab.getgrist.com/D3856

(core) API reworked to use POST to create webhook and DELET to remove it Summary: introduces POST /api/docs/{docId}/webhooks and DELETE /api/docs/{docId}/webhooks/{webhookId} on place of old _subscribe and _unsubscribe endpoints. Remove checking for unsubscribeKey while deleting webhook - only owner can delete webhook using DELETE endpoint. subscription key is still needed for _unsubscribe endpoint. old _unsubscribe and _subscribe endpoints are still active and work as before - no changes there. Posting schema: ``` POST /api/docs/[docId]/webhooks ``` Request Body: ``` { "webhooks": [ { "fields": { "url": "https://webhook.site/3bd02246-f122-445e-ba7f-bf5ea5bb6eb1", "eventTypes": [ "add", "update" ], "enabled": true, "name": "WebhookName", "memo": "just a text", "tableId": "Table1" } }, { "fields": { "url": "https://webhook.site/3bd02246-f122-445e-ba7f-bf5ea5bb6eb2", "eventTypes": [ "add", ], "enabled": true, "name": "OtherWebhookName", "memo": "just a text", "tableId": "Table1" } } ] } ``` Expected response: WebhookId for each webhook posted: ``` { "webhooks": [ { "id": "85c77108-f1e1-4217-a50d-acd1c5996da2" }, { "id": "d87a6402-cfd7-4822-878c-657308fcc8c3" } ] } ``` Deleting webhooks: ``` DELETE api/docs/[docId]/webhooks/[webhookId] ``` there is no payload in DELETE request. Therefore only one webhook can be deleted at once Response: ``` { "success": true } ``` Test Plan: Old unit test improved to handle new endpoints, and one more added to check if endpoints are in fact created/removed Reviewers: alexmojaki Reviewed By: alexmojaki Subscribers: paulfitz, alexmojaki Differential Revision: https://phab.getgrist.com/D3916

(core) Initial webhooks implementation Summary: See https://grist.quip.com/VKd3ASF99ezD/Outgoing-Webhooks - 2 new DocApi endpoints: _subscribe and _unsubscribe, not meant to be user friendly or publicly documented. _unsubscribe should be given the response from _subscribe in the body, e.g: ``` $ curl -X POST -H "Authorization: Bearer 8fd4dc59ecb05ab29ae5a183c03101319b8e6ca9" "http://localhost:8080/api/docs/6WYa23FqWxGNe3AR6DLjCJ/tables/Table2/_subscribe" -H "Content-type: application/json" -d '{"url": "https://webhook.site/a916b526-8afc-46e6-aa8f-a625d0d83ec3", "eventTypes": ["add"], "isReadyColumn": "C"}' {"unsubscribeKey":"3246f158-55b5-4fc7-baa5-093b75ffa86c","triggerId":2,"webhookId":"853b4bfa-9d39-4639-aa33-7d45354903c0"} $ curl -X POST -H "Authorization: Bearer 8fd4dc59ecb05ab29ae5a183c03101319b8e6ca9" "http://localhost:8080/api/docs/6WYa23FqWxGNe3AR6DLjCJ/tables/Table2/_unsubscribe" -H "Content-type: application/json" -d '{"unsubscribeKey":"3246f158-55b5-4fc7-baa5-093b75ffa86c","triggerId":2,"webhookId":"853b4bfa-9d39-4639-aa33-7d45354903c0"}' {"success":true} ``` - New DB entity Secret to hold the webhook URL and unsubscribe key - New document metatable _grist_Triggers subscribes to table changes and points to a secret to use for a webhook - New file Triggers.ts processes action summaries and uses the two new tables to send webhooks. - Also went on a bit of a diversion and made a typesafe subclass of TableData for metatables. I think this is essentially good enough for a first diff, to keep the diffs manageable and to talk about the overall structure. Future diffs can add tests and more robustness using redis etc. After this diff I can also start building the Zapier integration privately. Test Plan: Tested manually: see curl commands in summary for an example. Payloads can be seen in https://webhook.site/#!/a916b526-8afc-46e6-aa8f-a625d0d83ec3/0b9fe335-33f7-49fe-b90b-2db5ba53382d/1 .

The services are set to have zero workers until we need them. * These new workers are started with a new env variable `GRIST_WORKER_GROUP` set to `secondary`. * The `GRIST_WORKER_GROUP` variable, if set, makes the worker available to documents in the named group, and only that group. * An unauthenticated `/assign` endpoint is added to documents which, when POSTed to, checks that the doc is served by a worker in the desired group for that doc (as set manually in redis), and if not frees the doc up for reassignment. This makes it possible to move individual docs between workers without redeployments. The bash scripts added are a record of how the task definitions + services were created. The services could just have been copied manually, but the task definitions will need to be updated whenever the definitions for the main doc workers are updated, so it is worth scripting that. For example, if a certain document were to fail on a new deployment of Grist, but rolling back the full deployment wasn't practical: * Set prod2 tag in docker to desired codebase for that document * Set desired_count for grist-docs-prod2 service to non-zero * Set doc-<docid>-group for that doc in redis to secondary * Hit /api/docs/<docid>/assign to move the doc to grist-docs-prod2 (If the document needs to be reverted to a previous snapshot, that currently would need doing manually - could be made simpler, but not in scope of this diff).

(core) API reworked to use POST to create webhook and DELET to remove it Summary: introduces POST /api/docs/{docId}/webhooks and DELETE /api/docs/{docId}/webhooks/{webhookId} on place of old _subscribe and _unsubscribe endpoints. Remove checking for unsubscribeKey while deleting webhook - only owner can delete webhook using DELETE endpoint. subscription key is still needed for _unsubscribe endpoint. old _unsubscribe and _subscribe endpoints are still active and work as before - no changes there. Posting schema: ``` POST /api/docs/[docId]/webhooks ``` Request Body: ``` { "webhooks": [ { "fields": { "url": "https://webhook.site/3bd02246-f122-445e-ba7f-bf5ea5bb6eb1", "eventTypes": [ "add", "update" ], "enabled": true, "name": "WebhookName", "memo": "just a text", "tableId": "Table1" } }, { "fields": { "url": "https://webhook.site/3bd02246-f122-445e-ba7f-bf5ea5bb6eb2", "eventTypes": [ "add", ], "enabled": true, "name": "OtherWebhookName", "memo": "just a text", "tableId": "Table1" } } ] } ``` Expected response: WebhookId for each webhook posted: ``` { "webhooks": [ { "id": "85c77108-f1e1-4217-a50d-acd1c5996da2" }, { "id": "d87a6402-cfd7-4822-878c-657308fcc8c3" } ] } ``` Deleting webhooks: ``` DELETE api/docs/[docId]/webhooks/[webhookId] ``` there is no payload in DELETE request. Therefore only one webhook can be deleted at once Response: ``` { "success": true } ``` Test Plan: Old unit test improved to handle new endpoints, and one more added to check if endpoints are in fact created/removed Reviewers: alexmojaki Reviewed By: alexmojaki Subscribers: paulfitz, alexmojaki Differential Revision: https://phab.getgrist.com/D3916

* Maintain up to 5 buckets: current day, next day, current hour, next hour, current minute.
* For each API request, check in order:
* - if current_day < DAILY_LIMIT, allow; increment all 3 current buckets
* - else if current_hour < DAILY_LIMIT/24, allow; increment next_day, current_hour, and current_minute buckets.
* - else if current_minute < DAILY_LIMIT/24/60, allow; increment next_day, next_hour, and current_minute buckets.
* - else reject.
* I think it has pretty good properties:
* - steady low usage may be maintained even if a burst exhausted the daily limit
* - user could get close to twice the daily limit on the first day with steady usage after a burst,
* but would then be limited to steady usage the next day.
