Paul Fitzpatrick	876a0298a2	(core) do not look at content of recent actions when loading documents ... Summary: This removes the need for any information drawn from the content of recent actions when loading a document. The undo/redo system does need some facts about recent actions up front. But that system has an important restriction: only actions a particular client is known to have generated can be undone by that client. So in this diff, as we store which client has performed an action, we also store the few pieces of metadata about that action that the undo/redo system needs: `linkId`, `otherId`, `rowIdHint`, `isUndo` fields. These are all small integers (or in one case a boolean). An existing limitation is that information about which client has performed which action is stored in memory in the worker, and not persisted anywhere. This diff does not change that limitation, meaning that undos continue to not survive a worker transition. A reasonable way to deal with that would be to back the store with redis.

Dmitry S	00c1a0c688	(core) Log the time taken by decodeActionFromRow() operations. ... Summary: Decoding large actions is a plausible culprit for hogging CPU time for certain documents. To begin with, log the time taken for this operation, so that we can tell if it's a problem in practice. Test Plan: Should not affect any current behaviors Reviewers: paulfitz Reviewed By: paulfitz Differential Revision: https://phab.getgrist.com/D2989	3 years ago
Dmitry S	dfdb54fcbd	(core) When parsing ActionHistory into ActionGroups, avoid keeping many large actions in memory. ... Summary: Add a unittest that start the server with limited memory, and build just enough of ActionHistory to crash the server before this fix, and not after. Test Plan: Tested manually with various memory prints, and added a test. Reviewers: paulfitz Reviewed By: paulfitz Differential Revision: https://phab.getgrist.com/D2616	4 years ago
Paul Fitzpatrick	5ef889addd	(core) move home server into core ... Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
