[fixed] v3.6.0 crashes with broken maps

[tomreyn]

Unfortunately the 3.6.0 headless server seems to segfault on load. Please find below the output my development system throws (I also reproduced this on a real dedicated server, though):

Code: [Select]

$ ./dev_rungame --ini-path=./ --data-path=./ --headless-server-mode=vps,exit
Disabled reading from console [vps]
Forcing quit after game has completed [exit]

[small]Edit (tomreyn): Renamed this topic since it is about broken maps, not specific to headless server; add [fixed] tag[/small]

[softcoder]

Not exacty sure what is going on here but notice this part of the error:

Can't read pathname for load map: Eingabe-/Ausgabefehler.

What exactly is this weird name??

Also note, that when i run the headless with the same parameters I am able to connect and launch a game without any such error.

[titi]

Can't read pathname for load map: Eingabe-/Ausgabefehler.

is:
Can't read pathname for load map: Input-/Output error

[tomreyn]

I've always had the Can't read pathname for load map: input/output error - that's not new, and probably not the cause for this issue either: This part of the output is generated by gdb which is analyzing the core file which was written to disk after the game crashed and after its own stacktrace analyzer has done its work already (producing the stacktrace found twice above this message).

When I said I reproduced the bug I saw locally (whose log I posted above) on a dedicated server, then I was wrong there. I was tricked by the data package which contains a megaglest-3.6.0 subdirectory, causing these files to get extracted to said subdirectory and not being available to the game in the expected location (causing the game to fall flat on its face (?) when I tried to run it this way). So the dedicated is fine now and actually shows up onthe master server now - just PEBKAC there. However, the local issue prevails.

[tomreyn]

This finally turned out to be due to a broken map. Softcoder is working on a validation to prevent such situations in the future.

If you run into this issue, as a workaround, rename UserData_Root/maps to UserData_Root/maps-broken, then copy back the maps from UserData_Root/maps-broken to UserData_Root/maps one by one, starting the game after each map you copied back in place.

Alternatively, use a development build or r2957 or later and run it from a terminal window, it will show an error message which lists the problematic map (which you can then delete or move to a different directory).

[softcoder]

svn now displays a report about corrupt maps and filters them out from any lists. Also language issues are fixed as well for users with old reference to renamed languages. Alternately user could always force MG to start in their desired language via commandline:

--use-language=german

or whatever language. Also accept is your languages iso639-1 code, example chinese is:

--use-language=zh

Then you can go into the options menu and save the new language setting. The next minor release will have these changes.
