Server map rotation fails after a while about quake3e

[ec-]

I wouldn't bother supporting vanilla q3 qvms for anything other than 'authenticity' as it has a LOT of bugs and unpatched vulnerabilities, consider using baseq3a mod with dedicated rotation system

From what I can tell, this looks like a valid engine bug. In quake3e, SV_Restart is invoked automatically due to time overflow conditions, which calls the map console command, which calls SV_SpawnServer, which resets the nextmap cvar and breaks the rotation. In vanilla q3, it looks like the reset is done via vstr nextmap instead which allows the rotation to update nextmap and preserve itself.

I'd suggest that SV_Restart should not alter the nextmap cvar. Additionally, if there is any compatibility reason to keep the nextmap reset in SV_SpawnServer at all, it would probably be good if there was at least a cvar option to disable it to allow a setup where a standard rcon map command doesn't automatically break the rotation.

Did it stay on a map for multiple days? Without change? You might also not have sv_levelTimeReset set.

I am not entirely sure if it is the best idea to preserve the value of nextmap cvar upon forced restart on extreme long uptime or even the slightly less extreme long uptime either. There may be some corner case issues where setting it to the old value could break other mods, they would need to be tested and investigated if it is safe to do so.

The server can stay up without a map change for multiple days, though not typically 23 as mentioned in the first link. However, I've observed the problem even with clients on the server reaching fraglimit. I have timelimit set to 0. The map rotation will work fine for several maps as players reach fraglimit and will then begin to restart the same map over and over as nextmap somehow becomes set to map_restart 0.

I'll try setting sv_levelTimeReset and see if that helps.

Have you considered using the ec-/baseq3a mod? It has fixes plus also a replacement system for map rotation iirc.

Oh nice, I will look into it. Thanks.

To be clear, isn't vanilla qvm support important for mod compatibility? Mods based on the vanilla game may not implement every patch but it's still useful for the engine to support them as well as possible.

For reference, it looks like cnq3 does not reset or touch nextmap at all.
