I just tested the generic output protocol with non existing properties and it runs just fine, no segmentation fault here. I've also looked at the code and it does look correct. This is all with the generic network code from CVS. Maybe there is something else that is triggering the crash?

[Flightgear-devel] Recovering flight data
Hi every one ! I'm a Phd Student on data mining and prognostic , and I want to recover some aircraft flight data from FG for testing algorithms [?]. I writes an XML File *thesis.xml* ( in the *data/protocol* FG directory ) witch allow to have some information from generic input/output configuration. *thesis.xml* recover several flight on engine information,when i try a flight with a plane how don't have all the parameters FG crash. Can some one help me[?]Is there something to avoid program grach without removing elements from the XML file [?][?] thanks all !!!

If you want to replay the flight using data you've written to an output file you probably want to add --fdm=external to your command line. This will disable the internal flight dynamics model. Also make sure the input section of your configuration file matches the output section to be sure they use the same properties for both directions.

Re: [Flightgear-devel] Recovering flight data
Tahnks for the answer, actually I don't want to replay the flight, but extract information from the output file I get from FG. The problem seems to be that the xml file I put into data\protocol is looking for some plane informations it cannot find and FG crashes... Is there a way to make FG not crash when I use a plane that doesn't provide the information I ask from my XML file ? Or do I have to define a specific XML file for each plane ?

Would this actually be desirable? Right now the system balks if the property doesn't exist forcing an explicit declaration. Setting the create flag would allow typos, for example, to slip through silently. It would also lull you into thinking you were logging an interesting property, when in fact, you're just logging dummies.

Setting the create flag would allow typos, for example, to slip through silently. It would also lull you into thinking you were logging an interesting property, when in fact, you're just logging dummies. I suppose there are different philosophies of error handling, but having a hard crash is not my personal favorite. I like the idea of silently creating the property if it doesn't exist ... that is the way so many of our other systems work. If you have a nasal script that writes some output value and a gauge that displays it, if there is a typo in the gauge property, this will get created with zero or null value. Presumably a person would test their data logging before deploying it and would investigate why one or more channels is reporting zero. Perhaps another option would be to throw an exception if the property doesn't exist, which would presumably be caught somewhere and an appropriate message displayed. but I really don't like it when user generated configurations can produce hard segfault crashes with no error message other than segfault or bus error.
