Re: [Flightgear-devel] [PATCH] recent segfaults caused by jsbsim and property tree
On Thu, 12 Nov 2009, Csaba Halász wrote: Hi Everybody! Hi Csaba! Good work! As you may know we have been recently investigating mysterious segfaults experienced with some jsbsim aircraft such as the f16 or the hansajet. I have identified the following problems: 1) SGPropertyNode::getNode apparently stops parsing after an index. For example, given /foo/bar[0]garbage it happily returns the node /foo/bar[0]. 2) Certain overloads of SGPropertyNode::tie invoke getNode without checking the return value. 3) FGTurbine::Load is missing a slash in the prefix and so ultimately passes garbage to SGPropertyNode::tie. Did you manage to find out how that happens? I couldn't spot it in the code - AFAICS it doesn't happen in JSBSim/standalone and the involved JSBSim code ought to be the same. 4) The checkTied in FGFDMExec.cpp is assuming property nodes with children can not be tied. That's the one I found and fixed in JSBSim/CVS yesterday :) 5) All over jsbsim plain SGPropertyNode objects are cast to FGPropertyManager Additionally Anders has found some trouble too, I suspect he has checked in a fix to jsbsim cvs for that (but I haven't looked). The primary cause of the trouble is point #3, I have a simple fix attached for it as well as for point #4. These are against gitorious next branch but should be simple enough to apply manually if necessary. Even with these checks I get a segfault with the Hansajet. During testing, however, that worked as well. I had some other modifications that I thought were irrelevant but looks like i was wrong. I will re-apply those tomorrow. Apparently Tim has recently changed the props code, so I'll leave #1 and #2 for him :) Finally, point #5 needs some thought. Yes, indeed.

If I understand the old code correctly, it would treat /foo/bar[0]garbage as /foo/bar[0]/garbage, while the new code treats it as /foo/bar[0]. Was this intended to be valid property path syntax? I think it would be correct to throw an error in this case, but I don't want to break the world. Tim, I think culprit here are the garbage property names generated by JSBSim (#3). Somehow they don't (visibly) come out as garbage in JSBSim/standalone but with the change in behaviour you mention above I suspect that they indeed are garbage in JSBSim/standalone too, but just displayed differently. Should be easy enough to fix. Cheers, Anders -- --- Anders Gidenstam WWW: http://www.gidenstam.org/FlightGear/ -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

However, the addition of the slash is uneeded, as the slash is already included explicitly in the property name passed to Tie(). At least this is the case with JSBSim in CVS: Jon, I think the trouble here is an exception to the rule in FGTurbine.cpp (in Load()): The FGFunction name (most likely) does not have a leading '/', thus it gets the path propulsion/engine[0] + name without a '/'. I'll look into that when I get home.

OK , I had a feeling I misunderstood your ideas for changes ...

I would also like to keep the button to save the current FOV , since this is slightly different per aircraft , but I'd like other opinions on that as well ...

I'm going to investigate and comment as soon as my (spare) time permits, Just to add, Anders and I discussed my loading code on IRC, and it's definitely possible I am mis-interpreting some of the values in threshold.xml - especially relating to the displaced threshold value. According to the AptNav specs, the displaced threshold is included in implied runway length. To me it looks like, in contrast, you are adding the displaced threshold to the given runway length, which is not required here. From my experience I'd say, simply ignore the displaced threshold for startup position calculations - I suspect this is the way it has been in FlightGear all the time. The way I learnt it, the startup run starts at the beginning of the entire runway, anyway, no matter if they have a displaced threshold or not. This is different from the stopway/blastway which typically is not readily prepared (cleaned and checked) for aircraft movements. To my understanding there's just a little offset in startup direction added to the runway center endpoint at the startup position calculations to make sure that all aircraft wheels are getting situated onto the tarmac.
