rCOMM8a3e94c97c73: [lib] introduced rawMessageInfoFromServerDBRow function to reaction message spec

Summary

introduced rawMessageInfoFromServerDBRow function to reaction message spec. rawMessageInfoFromServerDBRow does some basic parsing of the message content from the db and returns the information necessary for a RawReactionMessageInfo object

UPDATE

Got some feedback to grab targetMessageID directly from the messages table instead of from messageContent. To do this successfully, I had to modify some of the message-fetchers queries to include targetMessageID in the query selection.

Depends on D5690
Linear Task: ENG-2245

Test Plan

Ran web and mobile app locally and nothing crashes/there are no regressions. More testing of this function will come in subsequent diffs.

UPDATE

To test that the queries were returning the correct information, I logged out row.targetMessageID.toString() and got this result, which matched what I found in the database:

(also note that the message content no longer has targetMessageID)

60	Is it intentional to not convert this id to string? What is its type in the db?
62	Are we still using this name?

60	Yea `content.targetMessageID` is already a string where the other IDs like `threadID` are numbers so we need to convert them to strings
62	Good catch! forgot to push the rebase for this diff yesterday

lib/shared/messages/reaction-message-spec.js
60	Something is wrong here. `targer_message` is defined separately in `message` table `target_message bigint(20) DEFAULT NULL` and is not a part of `content` json field. (at least on master). We have to make sure that type of `id` matches `target message id` and that the proper value source is used.

lib/shared/messages/reaction-message-spec.js
60	In D5698, I introduced `messageContentForServerDB` which handles putting the `content` into the DB. In this method, I did include `targetMessageID` in the content; however, after your comments and rethinking it, this might be unnecessary if we are putting `targetMessageID` separately in the `message` table` as `target_message`. Let me know what you think, and hopefully, this clears up the confusion.

keyserver/src/fetchers/message-fetchers.js
590–594 ↗	(On Diff #19240)	It might be a good idea to also update this select.
lib/shared/messages/reaction-message-spec.js
63 ↗	(On Diff #19240)	What happens when `target_message` isn't set. Is it safe to call `toString` on the result in such a case?
60		I think there's no need to write target message twice into the db. We introduced a separate column for that so that we can e.g. query by this and use an index.

keyserver/src/fetchers/message-fetchers.js
590–594 ↗	(On Diff #19240)	I didn't include this select because local messages won't have reactions at the moment, but I can update this select since we will probably one day want local reaction messages too
lib/shared/messages/reaction-message-spec.js
63 ↗	(On Diff #19240)	all reaction messages will have a `target_message` set but I will definitely add an invariant to make it extra safe

keyserver/src/fetchers/message-fetchers.js
590–594 ↗	(On Diff #19240)	While introducing optimistic liking we will probably make it possible for a reaction to be a local message. But regardless, I think that the code between db and js should be as general as possible and should have a minimal amount of business logic involved. So if we try to write this code only as a translation between one model and the other, we would be less likely to introduce bugs in the future.
