Addon Version Check Database Bug in Multiplayer Lobby #4055

JessePotterMusic · 2019-04-29T01:23:38Z

Hey there, just reporting this bug as I was asked by the developers. I couldn't join the game at the bottom of the list "segfaulted's game." Then this error came up.

I am running version 1.14.5
Hope this helps, thanks!

Likely reason is that the variables mp::game_info::required_addons and mp::game_info::addons_outcome are not in sync, meaning addons_outcome was set to something != SATISFIED without adding to required_addons. Like for example here:

wesnoth/src/game_initialization/lobby_data.cpp

Line 305 in 0b45d5e

addons_outcome = NEED_DOWNLOAD;

Ideally there should not be two variables that need to be in sync. All the info should be in one place.

I've seen this a couple of times recently, after building from source. I've just tried pressing "Create Game", and found that the only eras that are installed are the default four, although I definitely have Ageless installed in my add-ons folder. Purging the cache did not fix it, nor did exiting and restarting.

I then tried creating a local multiplayer game instead of connecting to the server. That gave the expected long list of eras, in the Create Game screen, After that, I joined the multiplayer server and my installed eras showed up.

So I've a suspicion that the database used when connected to the server is only being created when creating a local game.

Reported on Discord by the user Poison#2201, they also encountered this issue trying to observe a game using Default Era, Isar's Cross, and the mods:

color_mod
plan_unit_advance
Rav_Color_Mod

They themselves had quite a few add-ons installed, in part since they observe a lot of games:

For future reference, the game in question can be found in the database with AN INSTANCE_UUID of 8c91fa9b-7c8f-11ea-9d3a-0ee77816ca01 and a GAME_ID of 82810.

I did try observing that game as well, and was able to join without any issue. However, the only add-ons I had installed were the three mods listed above.

Is it with filesystem manipulation (e.g. removing add-ons), or without? I easily get it if I mangle with addons, but the issue always goes away if I clear the cache in Preferences and then press F5 in the main screen

Infor-Master · 2022-08-05T20:28:24Z

can confirm this still happening. First time i found this message while on Wesnoth 1.16.5. As some mentioned before, clearing cache didnt help

soliton- · 2023-07-14T23:21:23Z

For the record there is no database involved here. Just code checking the game info and getting confused.

gfgtdf · 2023-12-07T17:03:10Z

Is it with filesystem manipulation (e.g. removing add-ons), or without? I easily get it if I mangle with addons, but the issue always goes away if I clear the cache in Preferences and then press F5 in the main screen

It'd be still nice to have a reliable way to reproduce it, even with filesystem manipulation.

Pentarctagon · 2023-12-07T20:37:04Z

If nothing else, an error message that's actually accurate would be nice.

gfgtdf · 2023-12-07T23:10:58Z

Even if it would be that simple, we are already in string freeze currently

Pentarctagon · 2023-12-08T00:18:13Z

Writing a more sensible error message to the logs for now would still be an improvement.

So this randomyl happend to me on the 1.16 multiplayer server, so i took a look at what the client actually receives:

As you can see, in the [addon] section of the game the addon WoL_mods is marked as require = no , but below there are [modification]s from it (like WoL_mod_enable_armageddon) and there they are marked as require_modification = yes

gfgtdf · 2023-12-09T01:47:28Z

After downloading said addon, i noticed that the modifications inside indeed have require_modification=yes in them, so the error seems to be that in the [addon] section of the game the addon WoL_mods is marked as require = no for some reason

gfgtdf · 2023-12-09T02:08:56Z

The problem is that here we write require

wesnoth/src/mp_game_settings.cpp

Line 167 in 9877b8e

cfg["require"] = required;

But what we actually read is required

wesnoth/src/mp_game_settings.cpp

Line 144 in 9877b8e

, required(cfg["required"].to_bool(false))

Pentarctagon · 2023-12-18T01:39:17Z

@gfgtdf does this fix need to be forwardported?

gfgtdf · 2023-12-18T02:07:04Z

No 1.17 already has another fix

gfgtdf · 2023-12-18T02:07:28Z

(the fix for 1.16 is different for compatibility reasons)

Pentarctagon · 2023-12-18T02:44:10Z

So this can be closed?

gfgtdf · 2023-12-18T22:18:13Z

I'd say so, yes

gfgtdf · 2023-12-20T17:37:58Z

Actually while this fixes probably the most common cause, it can still happen in case of bad umc code, for example when one player modifies their addon to add a tag to it that the other players doesn't have.

I do think that we should still at least give a better error message in those cases.
