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.

Dmitry S	a91d493ffc	(core) Fix issue with 'UNEXPECTED ORDER OF CALLBACKS' in Client.ts. ... Summary: - Substantial refactoring of the logic when the server fails to send some messages to a client. - Add seqId numbers to server messages to ensure reliable order. - Add a needReload flag in clientConnect for a clear indication whent the browser client needs to reload the app. - Reproduce some potential failure scenarios in a test case (some of which previously could have led to incorrectly ordered messages). - Convert other Comm tests to typescript. - Tweak logging of Comm and Client to be slightly more concise (in particular, avoid logging sessionId) Note that despite the big refactoring, this only addresses a fairly rare situation, with websocket failures while server is trying to send to the client. It includes no improvements for failures while the client is sending to the server. (I looked for an existing library that would take care of these issues. A relevant article I found is https://docs.microsoft.com/en-us/azure/azure-web-pubsub/howto-develop-reliable-clients, but it doesn't include a library for both ends, and is still in review. Other libraries with similar purposes did not inspire enough confidence.) Test Plan: New test cases, which reproduce some previously problematic scenarios.

Paul Fitzpatrick	561d9696aa	(core) clean up interaction of forward auth with session ... Summary: For self-hosted Grist, forward auth has proven useful, where some proxy wrapped around Grist manages authentication, and passes on user information to Grist in a trusted header. The current implementation is adequate when Grist is the only place where the user logs in or out, but is confusing otherwise (see https://github.com/gristlabs/grist-core/issues/207). Here we take some steps to broaden the scenarios Grist's forward auth support can be used with: * When a trusted header is present and is blank, treat that as the user not being logged in, and don't look any further for identity information. Specifically, don't look in Grist's session information. * Add a `GRIST_IGNORE_SESSION` flag to entirely prevent Grist from picking up identity information from a cookie, in order to avoid confusion between multiple login methods. * Add tests for common scenarios.

Dmitry S	4f1cb53b29	(core) Converting server-side Comm.js to typescript ...
