A bunch of tests are failing locally, digging in.
EDIT: Basically all queries time out, they never return anything. Trying to figure out why.
Turns out a simple null => false
change fixed most tests! (ccd4ae5) 2 test failures remaining, 794 passing!
The only two tests failing are the ones for backtraces, are those meant to fail?
All backtrace tests are fixed! Unsure why those were failing since the backtraces were correct, just slightly different in formatting.
Anyways, all the tests pass now! :tada: @neumino I'm going to try this branch in prod I think, let's see if it fixes our errors.
Huh, some backtrace tests still fail on wercker even though they pass locally? 🤔
Even with this branch we're getting changefeeds dropping out:
ReqlServerError: The connection was closed before the query could be completed for:
r.table("usersNotifications").changes({
includeInitial: false
}).filter(r.row("old_val").eq(null).and(r.row("new_val").eq(null).not()).or(r.row("old_val")("entityAddedAt").ne(r.row("new_val")("entityAddedAt"))))("new_val")
.filter({
userId: "gVk5mYwccUOEKiN5vtOouqroGKo1"
}).eqJoin("notificationId", r.table("notifications")).without({
left: ["notificationId", "createdAt", "id", "entityAddedAt"]
}).zip().filter(function(var_278) {
return var_278("context")("type").ne("DIRECT_MESSAGE_THREAD")
})
And also the server crashing due to:

@mxstbr @thelinuxlich What is the final solution for this issue of changefeeds dropping?
@nikhilrayaprolu replace your database with something supported, seriously, who would trust their primary database to a project that hasn't received updates in 5 years?
You are right, but I am wondering from an engineering standpoint, how this issue was solved finally.
I had also read the discussion here, but looks like the complete discussion is unavailable after the shut down of spectrum. https://spectrum.chat/rethinkdb-old/general/changefeed-troubles~e0047056-899e-4bde-9493-20f8a7bb0919

Not using RethinkDB anymore 🙈
I am wondering from an engineering standpoint, how this issue was solved finally.
It wasn't.
@mxstbr I really liked the source code of spectrum, it has all features needed for a good online community. The only major issue I found in that is the choice of rethinkDB. Now an option for me is to see if I could convert the rethinkDB to MongoDB and use Apollo PubSub for real-time features (I think this is not a priority now but need to do this before I start facing scalability issues).
Since I am planning to host an online clubs for k12 kids with some customizations (gamification) and video rooms for them to collaborate and learn together, I cannot think of going with a solution like circle.so
You don't need mongodb for realtime features in 2022, graphql subscriptions over sse is a good choice
This takes the
linkedlist
branch from #135 and merges the latest master into it. We're running into connection errors, and we have tons of changefeeds, so I'm suspecting this could be the solution.I'm going to try and get all the tests to pass again.
