Server crash #1

Closed yavl closed 5 years ago

yavl commented 5 years ago

Server crashed few mins ago. Yesterday it crashed too with exactly the same backtrace.

How to reproduce: no exact instruction, but it crashes after some time (30 mins to few hours?)

why: I have no clue yet, but maybe due to some issue with zombie Respawn Ponts (visualized as armor pickup) or with engineer wall.

this time right after I tried to place respawn point, so it's more likely due to respawn points.

teoman002 commented 5 years ago

Are you sure, you want to use CLaser::DoBounce in the Infection Circle? I mean these lasers are constants and can't move by themselves.

yavl commented 5 years ago

Latest crash does not look like all previous bugs

@teoman002 I can't deduce what is the reason of that last crash

teoman002 commented 5 years ago

I hammered a zombie with biologist and then it crashed. But it can be something else ofc.

So the crash says:

#0  0x000000000043f12c in CLaser::DoBounce (this=0x0)
    at src/game/server/entities/laser.cpp:62
62                              m_Dir = normalize(TempDir);

What happens if we normalize zero or a negative number?

inline vector2_base<float> normalize(const vector2_base<float> &v)
{
    float l = (float)(1.0f/sqrtf(v.x*v.x + v.y*v.y));
    return vector2_base<float>(v.x*l, v.y*l);
}

If one passes zero to normalize, they number becomes infinity.

yavl commented 5 years ago

@teoman002 if I remember correctly, there was an issue in 0.6 infclass when boomfly did a server crash because of zero vector being tried to be normalized

teoman002 commented 5 years ago

So we now search for code, that passes directional data to Claser.

yavl commented 5 years ago

I have little experience with gdb, is it normalize function that causes the crash? If so, I could just check if m_Dir.x, y are not zero and give them fake values otherwise

teoman002 commented 5 years ago

@yavl Please add guards to CLaser such that normalize can't get zero directions. If direction is zero, then make it one. And please add a console msg if that happens!

yavl commented 5 years ago

crashed again (without teoman002's commit)

Looks like the problem is somewhere in LuaLoader::GetCirclePositions()... functions (thank to breton). I will look at them and try to fix later.
