5 bugs oO

[Fifi]

I got 5 bugs (from various client versions), which I kept in replays and planned to report, but keep forgetting.

Unfortunately, only two of them are visible on the replay, but I'm attaching all off the demos anyway, because maybe the bugs left some traces. I didn't remember about game log at the time, so I don't have it either (maybe the bugs visible on the replays will left some information in the game log after playing them?)... I guess I'll just try to describe what happened as precise as I can.

• (filename: "BUG, game crash - autorecord_2015-04-27_04-20-37.demo", 2015-04-27 04:20:57 CET)
  The first one is rather simple, the game just crashed without any apparent reason... maybe the fact that the replay crashes my game too can be of any help (if it contains the data which caused the original crash).
• (filename: "BUG, tee and dummy in one place, can't move.demo", 2015-05-09 08:21:17 CET)
  I connected to a map, then I connected my dummy. I don't really remember how, but from the original tee point of view, I happened to be in one place with dummy. I couldn't move and it visually seemed like I was stuck by the collision engine. I was able to move my original tee with dummy when I switched to it.
• (filename: "BUG, falling through floor, like through lagged laser one.demo", 2015-08-29 04:03:57 CET)
  This one is as weird as the second. I connected to a map and began falling through the floor, almost to the bottom of the map (I could move though, even if that resulted in going deeper into the walls I passed by), then I got teleported back to the start (moved a bit to the right, as I tried to move right during the fall). Then I falled again, got teleported back again (but this time much earlier, as far as I remember) and I just kept falling and going back (I was able to move my, I guess, real position all the time, but it was hard with so much distraction). It looked like a laggy gameplay while standing on a laser wall without AntiPing, hence the replay name.
  I think it may be caused by the new map background feature (which I haven't used or configured yet, though - so it's likely that the new code somehow damaged the way game layer is loaded), as it looked like a failure in getting the correct entities collision, connected with moving me back to a proper place by the corrections from the server. Ah, it might be relevant too - my AntiPing was off, as far as I remember.
• (filename: "BUG after launching Steam Overlay, game crash.demo", 2015-08-24 23:17:50 CET)
  This one is not necessarily DDNet bug, as it might be also my (or Steam) fault. I use Arch Linux and after putting DDNet Client in place of Steam Teeworlds, it didn't run. So I made this:

  Code: Select all

  #!/bin/bash
  export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH
  cd /[something]/DDNet/
  ./DDNet

  Which made DDNet Client work, but crashing after opening the Steam overlay (which I later "fixed" by... disabling it ><" I'm so pro sometimes).
  I guess it might be caused by Steam relying on it's own libraries, while I fed him with my system ones. xD But in case I'm wrong and it's some DDNet Client bug, I attached the replay.
• (filename: "BUG (probably), game crashed - 2015-08-30_03-11-42.demo", 2015-08-30 03:11:59 CET)
  I'm not sure if it's the proper replay, because it doesn't crash when I play it, but I remember some recent crash which (I guess) reminded me of all those bugs... I might have mistaken it with the Steam Overlay crash or the falling-through-the-floor bug, though. But if crashes leaves some traces in the replays (do they?), then maybe it's possible to check it, so I'm attaching it just in case.

(all replays were recorded at CET time)

When your client crashes it's not able to complete the demo file it is currently recording to, so it's unlikely to have traces causing a crash in it. The demo files which are causing a crash simply are incomplete which leads to undefined behavior.

Some of the bugs you mentioned sound pretty familiar to me, can you give us the exact dates of all the demo files you posted?

[Fifi]

Oh, I thought that replay crash is a result of the bugged game variables, thanks for explaining it. ^^

Sure:
"BUG, game crash - autorecord_2015-04-27_04-20-37.demo": 2015-04-27 04:20:57 CET
"BUG, tee and dummy in one place, can't move.demo": 2015-05-09 08:21:17 CET
"BUG, falling through floor, like through lagged laser one.demo": 2015-08-29 04:03:57 CET
"BUG after launching Steam Overlay, game crash.demo": 2015-08-24 23:17:50 CET
"BUG (probably), game crashed - 2015-08-30_03-11-42.demo": 2015-08-30 03:11:59 CET

Btw. Now I think that the falling-through-the-floor bug may also be caused by the server, but the other tees which played this map with me weren't experiencing it, so it's rather very unlikely.

Maybe a problem with prediction and collision that wasnt correctly initialized?

[east]

Probably, yes.

I think this bug is related to a problem with the timeout protection, should be fixed by now.

Oh, that would explain it even better.

I forgot to add this - I weren't able to reproduce any of this, each bug happened to me only once so far (maybe apart from the game crashes, but they probably both have different reasons). If I'll experience any of them again, I'll try to remember about collecting the game log, though. :c

Probably, yes.

Oh, thank you. ^^ Btw. I just wonder, were you able to reproduce any of the bugs somehow? You have said that some of them sounds familiar.
