number of satellite orbit segments resets

[wkitty42]

in the satellite settings (ALT-Z), i set my orbit lines segments to the following values...

number of segments : 60
segment length (s) : 5
fade length : 10 to 30

this gives me five minute long orbit lines and keeps the clutter on the screen down nicely... the problem is that when i exit 0.14.0, reload it, and reenter the ALT-Z settings, the segment length is reset to 15... it didn't used to do that... i always use ALT-Z to see how many satellites were updated, added and removed when i update my satellite TLEs... this bug is quite annoying when working with TLEs that are updated quite frequently several times a day...

here's my log again just to be certain that i don't leave any information out...

Are you pressed button "save as defaults" in plugin before exit?

[wkitty42 (wkitty42)]

yes, absolutely... numerous times in testing to ensure that i wasn't missing it...

here's a copy (without the TLE urls) of my [satellites] section before starting stellarium...

===== snip =====
[Satellites]
auto_add_enabled = true
auto_remove_enabled = true
hint_color = 0.0,0.4,0.6
hint_font_size = 10

===== snip =====

i start stellarium, hit ALT-Z, the orbit lines all jump in visual size and the satellites settings window shows 15 for the segment duration value... quitting without saving anything and restarting comes up with the segments short again... ALT-Z causes them to jump to 15 again... the value does not get saved to the config.ini... it is only when the program is running and you hit ALT-Z the !FIRST! time... i set it back to 5, do not save the defaults because they already are saved and exit the settings window... after that i can enter and exit from ALT-Z all i want and the lines and duration value will stay set to 5... if i quit stellarium, then the first time i ALT-Z, the duration value is reset to 15 again... set back to 5 and it will stay there for the remainder of the session no matter how many times i ALT-Z and exit the settings window...

[Alexander Wolf (alexwolf)]

Why you expected saving data into config.ini, if you do not pressed the "save settings" button?

[Alexander Wolf (alexwolf)]

Or I did not understand you?

[wkitty42 (wkitty42)]

i didn't expect the settings to be saved... i was checking to ensure that it wasn't being done automatically ;)

something in the initialization when first using ALT-Z is forcing the segment duration to back to the default of 15... that is what is wrong... it is probably a one line fix... i'd fix it and provide the patch but i don't do C/C++... i used to read it years ago but i've spent more time with other code (pascal, perl, nasal, php, bat, rexx, etc)...
