Remove unused variables ADMIN, POLICYCHILDREN and CHILDRENID from "common" system technique metadata
Description
I'm not sur about the version for which this is the case, it should match the change done for relay servers.
I'm not sur about ADMIN, I believe it was already removed in 2.10.

POLICYCHILDREN and CHILDRENID were removed in 2.8, ADMIN in 2.10.
I'm openin another ticket for ADMIN

ha, it is a bit more complex than that, as it fails at deployment

Ok, it doesn't fail, it just complains in the log that some variables cannot be stored, but it works

I don't understand this ticket. Removing stuff is not a bug. What is the actual bug (what doesn't work or is broken here?). Please clarify.
Updated by François ARMAND over 10 years ago
Having dead code is a bug:
- it may be call in unwanted or unknown way, leading to bigger problem (security pb) and/or extremely hard bug to reproduce
- it may send bad message to future mainteners, thinking that something is used but is actually not.
That's of course generalities, but in that precise case, these variables were still present in technique metadata but not used for the promise generation, so we add a desynchronisation between technique metadata and actual variable, and we were paying a non negligible processing time for them for nothing.
Moreover, they were the only remaining use cases of the ${rudder.ruleid.target.XXX} parameter kind, blocking a possible major simplification (see #4585)

Thanks for the clarification.
I agree this needs removing, however, in the interest of stability, we must avoid making unnecessary changes, and in particular any changes that don't fix a problem suffered by users in released branches. Can we retarget this to 2.10?

Well, they should have been removed along with the introduction of MANAGED_NODES_NAME and MANAGED_NODES_ID in #4033 (so in 2.8), but I'm ok to remove them only in 2.10.

Great. Assigning to Nicolas to retarget the PR.

Oh, and to respond to this, let me clarify what my problem here is: maybe having dead code is a bug, but the title of this ticket never mentions dead code. It is expressed exactly like a "Let's remove some stuff" ticket which sounds scary, whereas it should be more like a "Let's clean up this unused stuff" which sounds good.
Titles matter. A lot.

Nico, could you retarget the associated PR (and other for the children) to 2.10 (given all the discussion above ?)
Thanks !
