Jonathan Perret	96b652fb52	Support HTTP long polling as an alternative to WebSockets (#859) ... The motivation for supporting an alternative to WebSockets is that while all browsers supported by Grist offer native WebSocket support, some networking environments do not allow WebSocket traffic. Engine.IO is used as the underlying implementation of HTTP long polling. The Grist client will first attempt a regular WebSocket connection, using the same protocol and endpoints as before, but fall back to long polling using Engine.IO if the WebSocket connection fails. Include these changes: - CORS websocket requests are now rejected as a stronger security measure. This shouldn’t affect anything in practice; but previously it could be possible to make unauthenticated websocket requests from another origin. - GRIST_HOST variable no longer affects CORS responses (also should not affect anything in practice, as it wasn't serving a useful purpose)	3 months ago
Paul Fitzpatrick	472a9a186e	(core) control the distribution of attachment metadata ... Summary: for users who don't automatically have deep rights to the document, provide them with attachment metadata only for rows they have access to. This is a little tricky to do efficiently. We provide attachment metadata when an individual table is fetched, rather than on initial document load, so we don't block that load on a full document scan. We provide attachment metadata to a client when we see that we are shipping rows mentioning particular attachments, without making any effort to keep track of the metadata they already have.

Dmitry S	51ff72c15e	(core) Faster builds all around. ... Summary: Building: - Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast. - Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var. - Grist-core continues to build using tsc. - Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned on, so that tsc accepts and enforces correct usage. - Client-side code is watched and bundled by webpack as before (using esbuild-loader) Code changes: - Imports must now follow ES6 semantics: `import * as X from ...` produces a module object; to import functions or class instances, use `import X from ...`. - Everything is now built with isolatedModules flag. Some exports were updated for it. Packages: - Upgraded browserify dependency, and related packages (used for the distribution-building step). - Building the distribution now uses esbuild's minification. babel-minify is no longer used. Test Plan: Should have no behavior changes, existing tests should pass, and docker image should build too.

Paul Fitzpatrick	c6d66e15bf	(core) configure typedoc for generating plugin api documentation ... Summary: This annotates the plugin api sufficiently to generate some documentation for it.
