Unreliable terrasync

Postby mathieugouin » Sat Feb 23, 2019 2:45 am

Hello,

I'm not sure I'm posting to the right forum...

I experience what seems to be unreliable terrasync download.

I have FG 2018.1.1.

I have enabled terrasync from my .fgfsrc as:
Code: Select all
--enable-terrasync


The terrain is loaded but the some objects are sometimes not present.

I looked at the fgfs.log. From there I see lines that worry me. I have listed only lines with terrasync & failed in them. Let me know if you would need the full log.
Code: Select all

Could this be because I run a too old FG version?

Thanks in advance!

No, it is likely that there are none of those objects in that tile directory... Oh, wait... That's failed to sync?? I can't check my system right now but if you post a "reminder" message, I can check it out next time I'm on in a few hours...

Sure I will remind you in a few hours.

If it can help investigation, I added a few weeks ago some objects around CYHU using the scene models map. The objects got approved and I see them on the scenery map.

Could this be that not all mirrors are updated at the same time?

Thanks again!

it is possible that a/some mirrors are not fully up to sync... if that's the case, then a note in the developer's mailing list on SF generally takes care of that...

now that i've had some sleep and a few minutes answering this post, i can say that the messages you posted above are legitimate and normal... the "w080n40" directory simply does not exist in the "Buildings", "Roads", or "Pylons" directories in terrasync... you'll see the same types of messages when flying over areas that don't have objects in them... FG will make requests to see if there are objects and if not, it will report that with messages similar to those above...

Do you recommend I post a question about that on the mailing list?

Thanks

only if the mirror(s) your system uses are not up to date...

Ok, I have confirmation of a faulty mirror:

Code: Select all
terrasync:3:/build/simgear-neYw_f/simgear-2018.1.1+dfsg/simgear/scene/tsync/terrasync.cxx:630:terrasync scenery provider of the day is 'https://ukmirror.flightgear.org/fgscenery'

are you saying that you are not having the same tile problem with the other scenery servers?
the line above is only telling us that your sim has chosen the ukmirror server but nothing about the tiles you were reporting as problematic with some other server...

I'm saying with this mirror, the tower I added for CYHU airport is not showing.

Is it possible to force another mirror?

I'm not sure how the mirror selection works but I'm surprised to be directed to a UK mirror while I'm in Canada...

there are only a few mirrors, currently... yes, you can force a scenery server... i use the following in the launcher's "additional settings" box or in a --config=blah.xml or in a .fgfsrc...
Code: Select all
################################################################
# terrasync server overrides.
# FG will use the uncommented entry for terrasync.
# remember to uncomment only one entry at a time.
################################################################
#--prop:/sim/terrasync/http-server=automatic
--prop:/sim/terrasync/http-server=http://flightgear.sourceforge.net/scenery
#--prop:/sim/terrasync/http-server=http://fgfs.goneabitbursar.com/terrascenery
#--prop:/sim/terrasync/http-server=http://ns334561.ip-5-196-65.eu/terrasync
#--prop:/sim/terrasync/http-server=https://ukmirror.flightgear.org/fgscenery

#--prop:/sim/terrasync/http-server=https://mpserver16.flightgear.org/scenery
################################################################


when automatic is selected, FG will query the DNS for NAPTR records to select which terrasync server to use... a couple of them are currently disabled... you can find them with the following command
Code: Select all
dig terrasync.flightgear.org ANY
... that's how i got the above list that i'm using...

the above command will return results similar to these

That is a perfect explanation! Thank you very much!

This way I'll be able to test other servers to confirm which one are not updated.

I'll report back.

Here are my reports of server update status. I performed my tests on the CYHU airport. I recently added a tower and if I see the tower, it is my cue for an updated server. Sitting on the 06L runway, the tower should be slightly at the right, down the runway.

I tried various server with the --props in my .fgfsrc

  • --prop:/sim/terrasync/http-server=automatic : not updated, probably falling back to ukmirror
  • --prop:/sim/terrasync/http-server=https://ukmirror.flightgear.org/fgscenery : not updated
  • --prop:/sim/terrasync/http-server=https://dream.t3r.de/fgscenery : updated
  • --prop:/sim/terrasync/http-server=https://mpserver16.flightgear.org/scenery : updated
  • --prop:/sim/terrasync/http-server=http://flightgear.sourceforge.net/scenery : updated
  • --prop:/sim/terrasync/http-server=http://fgfs.goneabitbursar.com/terrascenery : did not try because of the disabled dig report
  • --prop:/sim/terrasync/http-server=http://ns334561.ip-5-196-65.eu/terrasync : did not try because of the disabled dig report

Can somebody with server knowledge confirm the issue?

On my side, I can work with hardcoding a server, but the fact that the airport was sometimes showing up, sometimes not was driving me nuts... probably the automatic server setting alternating between an updated vs non-updated server.

Thanks!

This looks like the syncing of the ukmirror hangs. I just sent a heads up to it's operator.

FWIW the .dirindex file at the root of the scenery directory has a timestamp:

See that the ukmirror has not received any updates since November last year and the Objects hash differs. Interesting that nobody noticed earlier.

Thanks for pointing this one out. And sorry for the trouble this caused.

Database updated, elevation values for LZIB are new, evening will test in FG.

EDIT :
Object's elevations are OK.
