Clojurians Log v2

I was just returning to this channel because it happened again... and yeah it seems like it happens on initial setup. What's the recommended version to revert to?

0.9.8 seems to work

Yeah 0.9.8 doesn’t have the issue. I tried looking into what the actual cause was but I’m out of depth. I’ve just got this commit checked out: 14502e772184a9564131e92575c554e724917be2 https://github.com/juji-io/datalevin/commit/14502e772184a9564131e92575c554e724917be2

Fixed in master

Sounds like it might be related to this issue https://github.com/juji-io/datalevin/pull/269

Amazing, I’ll switch to the latest master commit. 🚀

Ahh so count were not happening when a-size was zero. Did that cause the query planner just to ignore that attribute completely?

Right, the shortcut in the query processing will return nil immediately when some attributes found to have zero size.

I will try today. Fast attempt to isolate case yesterday failed :(

duckie So… the rubber duck works. While trying to create an isolated case, I found out that there was an error in the :tariff/servers value, which is also a ref type with :db.cardinality/many. I had to include reverse lookups there. However, the error message is a bit confusing, though…

What kind of error?

If it is something that the system should check for, we can add the check

I put in :tariff/servers such a vector like [:serv-1 :serv-2 ...etc...] , but :serv-1 and others are values of :server/id . I had to put reverse lookup there. So, the problem was that system complained about problems with transient maps, but better would be to say something like "Values in :tariff/servers have to be existent :tempid or reverse lookup clause, but found ':serv-1'"

ok, maybe file an issue so we can add such checks?

tempids collection is transient. so some error in the transaction logic

somewhere in the db.clj

could you isolate a test case?
