Crash when satellite EL=-0.00 at AOS in 00:00 #332

emmanuelCNRS · 2023-05-22T11:44:01Z

Dear Gpredict Team,

I would like to submit several crash of Gpredict when AOS is 00:00 and satellite EL is -0,00°.
Gpredict run with rotctld.
Gpredict version is win32-2.3.37 (on Windows7).

In attached pictures, two crash examples when AOS on UVSQ-Sat and INSPIRE-Sat7.
Could it be fixed with parameters adjustment ?

Best regards.

I have not recorded the Gpredict log when the software crashed, but may-be the current log could help.
There are several lines like these ones:
2023/05/22 07:36:05|1|get_current_pass: Returning a pass for INSPIRE-SAT 7 that ends before the seeded time.
2023/05/22 18:21:58|1|get_current_pass: Returning a pass for UVSQSAT that ends before the seeded time.

Hereafter the full log:
gpredict.log

Best regards.
Emmanuel

Don't know if it could help, hereafter an exemple of the many crash reports saved by Windows:

#1 What do you have for your pass conditions?
#2 Please run rotctld with this added: -vvvvv >log.txt 2>&1
Then we can make sure it's no a rotctld problem.

emmanuelCNRS · 2023-09-29T09:46:31Z

Hi Michael,
Thanks for your comment, hereafter the pass conditions:

And hereafter the rotator configuration:

Rotctl is usualy used with:
"C:\Program Files (x86)\hamlib-w64-4.4\bin\rotctld" -vvvv -m 603 -r COM6 -s 4800 -t 4533 -C timeout=2000

Call to Rotctl have been modified has suggested (-vvvvv >log.txt 2>&1), hereafter the beginin of the log:
log_20230929.txt

I will post the updated log as soon as next crash.

Thanks for your help :-)
Best regards,
Emmanuel

Hi Michael,
I have captured a crash in the log (if needed I can share the entire file on an ftp):
log_20231002_Extract.txt

At line 398122 you can find this:

fscanf: Invalid argument
fscanf: parsing '
' with '%c'
Connection closed from ::ffff:127.0.0.1:61324

Best regards,

Try the latest Hamlib -- is has better debug info and hopefully fixes this problem too. gpredict is sending bad data for some reason.

Hello Mike,
Thanks, I have updated hamlib to "w64-4.5.5" version.
Waiting now for next satellites pass.

Best regards,

Hello Mike,
Thanks, I have installed "hamlib-w64-4.6~git-20231003-c9344070".

Try tonight's build -- will be dated 20231007 It has more debug info so we can see what gpredict is sending.

Hi Mike,
Thanks, nightly build downloaded today and just installed.
Begining of log is:
rotctld, Hamlib 4.6~git 2023-10-08T22:18:16Z SHA=e68b6f 64-bit

Emmanuel

emmanuelCNRS · 2023-10-12T14:34:02Z

Hello Mike,
Gpredict has crashed yesterday with the nightly built "Hamlib 4.6~git 2023-10-08T22:18:16Z".

The beginning of rotctld log is:
log_20231011b - Beginning of file.txt

And the end with the unexpected gpredict crash is:
log_20231011c - End of file.txt

Best regards,
Emmanuel

mdblack98 · 2023-10-12T20:55:18Z

Are you compiling gpredict yourself? I'd like to provide a patch for gpredict to figure out why it is sending a NULL byte.

Hello Mike,
No, I'm using the already compiled EXE available on https://github.com/csete/gpredict/releases
Version is "gpredict-win32-2.3.37".
If you send me a new EXE I can launch it in our ground station.

Best regards,
Emmanuel

emmanuelCNRS · 2023-10-18T07:23:38Z

Hi Mike,
Please find hereafter some other log of rotctld (Hamlib 4.6~git 2023-10-08T22:18:16Z) with the unexpected closure of Gpredict.
log_20231018_Extract.txt

The last one, at the end of the file, is not EL=000. But probably same problem since EL=179 is the opposite position (gpredict EL configured with EL in [0° ; 180°] range).

I have not recorded gpredict internal log, will be done next time, but should be something like this previous one:

2023/05/22 07:36:05|1|get_current_pass: Returning a pass for INSPIRE-SAT 7 that ends before the seeded time.
2023/05/22 18:21:58|1|get_current_pass: Returning a pass for UVSQSAT that ends before the seeded time.

Do you know where does come from "that ends before the seeded time" trace in gpredict?

Best regards,
Emmanuel
