Triple like_ship crash?!?

[Lestradae]

Perhaps someone can make something of my error log.

For a week now, I have strange slowdowns and de-facto crashes (the game freezes completely) with my new oxp I'm working on.

I have gone through everything x times, but don't find what's wrong. I use the new options of is_template and like_ship masively, with like_ship triple relations. But, according to the devs, that should not be a problem.

I can't seem to find anything in my error log, though. This log was taken after a sloooowdown -> freeze with only my oxp and all dependant oxps in:

Can someone see something potentially useful in there? I can't.

Addendum: It say in the logcontrol.plist that I can get more info out of the log:

Log output can be modified using the following preference keys:
logging-show-app-name
logging-show-class
logging-show-function
logging-show-file-and-line
logging-echo-to-stderr

Erm ... and how, exactly, do I do that?

[Commander McLane]

Well, the two error messages are very easy to understand. Let's start with the second one:

[plist.parse.foundation.failed]: Failed to parse AddOns/Missiles and Bombs v1.2.oxp/AIs/missileAI.plist as a property list using Foundation. Retrying using homebrew parser. WARNING: the homebrew parser is deprecated and will be removed in a future version of Oolite.
Parse failed at line 2 (char 25) - extra data after parsed string
[plist.homebrew.parseError]: Property list isn't in XML format, homebrew parser can't help you.

It tells you exactly what's wrong: The file 'missileAI.plist', which you find inside the OXP 'Missiles and Bombs v1.2.oxp' is corrupt (has an error in it), and can therefore not be read and used by Oolite. It even tells you in which line of the file to look for the error. What more do you want?

The first one:

[shipData.merge.failed]: ***** ERROR: one or more shipdata.plist entries have like_ship references that cannot be resolved:

It simply tells you that one or more shipdata-entries are linked via like_ship to another entry/entries that doesn't/don't exist.

There a dozens of possible reasons for that. Most likely you have either not all OXPs your OXPs is depending on installed, or you have made a typo/typos in one or more of your like_ship-keys. (For instance, linking via like_ship to an entry 'anconda-player' (instead of 'anaconda-player' would of course not work and produce this error.)

[JensAyton]

If you post the OXP somewhere, one of us godlike beings of light with trunk builds can tell you which shipdata.plist entries have like_ship references that cannot be resolved (that error message has been fixed). I probably can’t do it today, because I’m about to go and do some of that Real Life stuff.

[Lestradae]

Thanks again, guys.

@Cmdr McLane:

Didn't care that much about the missileAI as this one can't be the culprit, as it works without problems in other configurations. So Ramirez is innocent. I must have done something with the like_ship trees I use. But corrected those errors in Missiles & Bombs now anyways.

I'm surprised that a disfunctional like_ship link leads to such a freeze-over, and wasn't able to find the error by going through the relevant part of the shipdata.plist myself. OK, perhaps that's the problem.

*looks heavenward*

Thanks for the offer, the oxp - to anyone else, this is a WiP version NOT YET INTENDED OR SUITABLE TO BE USED IN NORMAL PLAY!!! - can be found here:

http://www.box.net/shared/static/433cozr1kv.zip

The like_ship error must be somewhere in shipdata.plist, if it is there.

The WiP contains a (hacked test pilot) savegame with an Overtuned Juggernaut. The freeze problem can be observed with any ship, though, including the Jameson Cobra Mk III

Thanks very much you have a look at it, that's appreciated

[JensAyton]

The fixed error message is:

Code: Select all

 [shipData.merge.failed]: ***** ERROR: one or more shipdata.plist entries have like_ship references that cannot be resolved: interstellar-escortscavengerhermitexplorer, tiger-mk1-navy, tiger-mk1-pirate, tiger-mk1-police

A quick check confirms that these four ships are based on two templates that don’t exist.

[Lestradae]

Thanks again, Ahruman

BTW, that was not the reason for the freeze. A betatester of OSE found it in the meantime ... so I can continue oxp'ing.

Cheers
