v1.74.2 and v1.75 trunk ship mutated?

[Switeck]

Ships are getting "mutated", and I neither know what "mutated" means nor how to fix them:

[exception]: ***** Exception during [update:entity [<ShipEntity 0x115ea628>{"Cobra Mark III" position: (-3242.52, 656593, 686957) scanClass: CLASS_NEUTRAL status: STATUS_IN_FLIGHT}]] in [Universe update:] : NSGenericException : Collection <OOShipGroup: 0xa9a98e8> was mutated while being enumerated. *****

My setup:
Win XP Pro SP 3, 1 GB DDR1 SDRAM, Geforce 2 GTS AGP 4x video card with paltry amounts of ram on it (32 or 64?)

Here's my log:

[another_commander]

Can you reproduce it with the latest nightly? It looks like you don't have that many OXPs (although I am not sure what that Various.oxp really is), so it would be helpful to find out which of them is causing the exception to kick in.

[Switeck]

I'll try testing again with the latest trunk...downloaded less than 2 hours ago for Wed. Feb 9th, 2011.

"Various.oxp" is a hand-packed-together (by me) grouping of multiple OXPs:
display-reputation-contract 1.1
display-reputation-passenger 1.1
rockHermit_Locator 1.3.3
targetAutolock 1.10
TrafficControl 1.1
Welcome Information Script 1.1

It also contains Military Missile, my replacement Commodities file for LOTS of stations, and my keyconfig.plist
I created it to work on my scripting and OXP skills, and it's a work-in-progress. It's quite possible there's typos in it, but usually I spot and remove those.
Note also any of the other OXPs may be edited...so I'll eliminate what I can in testing.

...If I knew just a little more of the nature of the error, I could probably eliminate a lot of OXPs.

[Kaks]

Ships are getting "mutated", and I neither know what "mutated" means nor how to fix them:

[exception]: ***** Exception during [update:entity [<ShipEntity 0x115ea628>{"Cobra Mark III" position: (-3242.52, 656593, 686957) scanClass: CLASS_NEUTRAL status: STATUS_IN_FLIGHT}]] in [Universe update:] : NSGenericException : Collection <OOShipGroup: 0xa9a98e8> was mutated while being enumerated. *****

No mutated ships, honest!

A mutated collection means: there were 3 (or 2, or 5) objects (in this case ships) inside this collection (in this case a OOShipGroup) when the code started enumerating them (going through all the ships in the ship group one at a time) - there's now a different number of objects inside the collection and the code isn't through enumerating them.

The most likely explanation is that one ship in the same group died as the universe display was being redrawn.
This problem, or something very similar, has been found & corrected in trunk a while ago.
If you try the nightly build it should hopefully confirm that the problem you've encountered is indeed the one solved already.

[Commander McLane]

No mutated ships, honest!

... although spontaneous mutations of pilots in the radiation-rich environment of witchspace have been rumoured about...

[Smivs]

Nonsense!
This was me before my spacefaring days



and this is me now.



No difference at all.

*has a fit of giggles at the thought of mutating ships in Ooniverse*

[DaddyHoggy]

*has a fit of giggles at the thought of mutating ships in Ooniverse*

Read Lazarus in the Fiction section - that's all about ship mutations... (clearly a rather portentous story!)

[Switeck]

I've narrowed it down a lot...so much so that the zip of my Addons folder is actually pretty tiny:
http://www.mediafire.com/?ab35zei27t940mt

What I don't get is in 1 of the logs I see this repeated MULTIPLE times with other presumably unrelated "events" separating it:
[exception]: ***** Exception in pollFlightControls [shoot]: NSGenericException : Collection <OOShipGroup: 0x70cbaa0> was mutated while being enumerated.
It's always <OOShipGroup: 0x70cbaa0> ...quite odd!

I included it in the zip found here:
http://www.mediafire.com/?ab35zei27t940mt

My guess is, based on what Kaks said, my Switeck mod...which is in a state of flux while testing. I had escortAI.plist and dumbAI.plist start out their global section with this:
ENTER = (becomeExplosion);
...Which removes all the unwanted objects so I could more easily test with 200+ active NPC ships. (minus their escorts)

...That may not explain why sometimes a mutated ship is named and other times it's <OOShipGroup: 0x70cbaa0> !

[JensAyton]

The exploding escorts don’t immediately trigger the error in trunk or 1.74. I’ll leave them both running while I’m at work.

[Kaks]

No mutations here either. Could you give us a copy of your save game & a brief description of what to do with it eg:

after loading the savegame, I jump to system x, fly around for y minutes, then exit oolite. At that point I the log always contains the mutation entry...

- or something along those lines...

[Switeck]

I don't know what triggers it and sometimes it happens within 5 minutes, and other times I can go for hours and it doesn't happen.

[another_commander]

Code: Select all

exception]: ***** Exception in pollFlightControls [shoot]: NSGenericException : Collection <OOShipGroup: 0x559d388> was mutated while being enumerated

This code refers to something that happens when you fire lasers. The reason I asked if the problem is repeatable in the latest trunk is that Ahruman recently fixed some problems that occured after a revision of the laser shot implementation. The trigger for the exception is in PlayerEntityControls.m, around line 755 of the latest trunk:

Code: Select all

exceptionContext = @"shoot";
//  shoot 'a'
if ((([gameView isDown:key_fire_lasers])||((mouse_control_on)&&([gameView isDown:gvMouseLeftButton]))||joyButtonState[BUTTON_FIRE])&&(shot_time > weapon_reload_time))
{
	if ([self fireMainWeapon])
	{
		[self playLaserHit:[self shipHitByLaser] != nil];
	}
}

Whatever it is that goes wrong, it goes wrong inside here or in the code that gets called from here. Anyway, please confirm what happens with latest trunk and then we can see how we can make it repeatable, if possible.

[Switeck]

I had a crash to desktop with this error being the last thing in the log file:
[exception]: ***** Exception during [update:entity [<ShipEntity 0x7cab010>{"Anaconda" position: (-4433.96, -7397.54, 13814) scanClass: CLASS_NEUTRAL status: STATUS_IN_FLIGHT}]] in [Universe update:] : NSGenericException : Collection <OOShipGroup: 0x7609108> was mutated while being enumerated. *****

...But this was using yesterday's build.
I'll test today's build after I sleep again.

I'm using the Omega ship in my testing...it may be to blame.

Here's one of the savegames I'm using with it:
http://pastebin.com/wPUSRZwJ

New update to report:
I started from scratch with a brand new game, hacked it to have 10 million credits, made my first jump to Zaonce, bought injectors, large cargo bay, and Advanced Space Compass, set TAF to 16x, jumped to Qutiri ...and within moments I got a crash-to-desktop with this as the last messages in the log:

Having run with your AddOns folder and saved game for many days of game time (yay TAF and multiple copies of Oolite), I still haven’t been able to recreate this. I have to conclude that it isn’t a critical blocker.

If anyone else wants to try to catch this in GDB, and at least get a call stack, the exception is thrown att OOShipGroup.m:465.
