Merge lp:~stellarium/stellarium/ip-query-location into lp:stellarium

[Alexander Wolf]

1) Added IP-based location query for location panel and optionally at program start.
2) Improved location GUI:
   (a) clicking on the map reduces site list to sites in 3 degrees vicinity.
   (b) selecting a country in the combo box reduces site list to sites in that country.
   (c) selecting a planet other than earth reduces site list to sites on that planet.

I checked this feature and it good work! But one moment: I think that label "IP Query" on button is not very informative and we should add tooltip and describe it.

[Alexander Wolf (alexwolf)]

The second feature is OK for me. Are you want merge it yourself?

[Alexander Wolf (alexwolf)]

Wait! What about non-Earth location?

Hm, I was surprised that the site list mixes all sites anyhow. I will try
to reduce selection to the currently set planet...

This list is "correct". I meant new features. If I change the planet and picked some point on the map (as example on Mars) then I get locations from Earth!

[gzotti (georg-zotti)]

Sure. This context info did not exist previously...

I filter also by current planet name now. And I want to add a filter for
country as next step towards better usability.

It's introduces important problem: search tool will search location in full
list or in filtered list?

--
With best regards, Alexander

[gzotti (georg-zotti)]

The list box gets filled with a preselected short list of nearby locations
on the current planet. If the user selects Earth, the complete list will
be shown at the moment (50 non-Earth entries in 15000 locations, should
not matter...)

The search tool is directly connected to the list, so it only searches in
the pre-filtered list.

There is a reset list button to recreate all entries.

I am not yet sure if I shouldn't clear out the country combobox if
planet!=Earth. This was always quite strange...

[Fabien Chéreau (xalioth)]

Hi Georg,

now that I'm back from holidays, I could acutally try the code, and I have
some more general comments about your (very very good!) work:

 - we should rename "IP Query" to something less technical, like "Get
location from Network"

 - I think the IP location is such an improvement that it should be the
default for all new install, and also probably used by default for installs
where the location was never set (set to Paris). This would imply that we
transform at startup all older config.ini from location = Paris, France to
location = auto. And use this "auto" value to trigger IP Lookup instead of
adding a new "init_location/use_ip_geolocation_if_available" key.

- Also when the lookup is successful, we could save the last know location
into an "init_location/last_resort_location" for the next time we start
without network.

Sorry to give these feedbacks so late, I hope they make sense, what do you
think? In any case, I think the lack of auto location feature was the most
annoying problem of Stellarium for an average user living in US, so thanks
a lot again!

Fabien

[gzotti (georg-zotti)]

Dear Fabien,

thanks for your friendly words.

I know "IP query" is very technical. But what to write on a 6-letter
button? Else, the button must stretch over the whole window, I did not
want to make it too intrusive. If there is space, it should be
"approximate location", my own query is about 50km off... But it's still
quite a good start.

A default IP lookup for new installs seems fine, as long as there remains
a fallback location in case someone travels to his offline PC with an USB
stick with the latest version. (When I traveled to Namibia for some
astrophotos with a Stellarium-guided telescope, my Atom netbook was also
definitely offline...)

Having the always-auto-lookup-at-start feature is OK. But It must be
possible to set and keep a home position as well, even if we are online at
startup. (And if somebody in Paris is happy with startup location, he will
be surprised to find his place renamed to IPxxxx :-)

The other changes are with finding a location near map-click point and
with the country/planet comboboxes. I think they are much more functional
now. What may still be done is to deactivate and empty the country box if
we are not on Earth.

My short slot of time is unfortunately over for this weekend. So, if you
like it, please merge and feel free to tweak these small details.

I just tried your brother's no-bit-field branch. It compiles on my Atom
450 netbook (MSVC2012/Angle; takes ages...), but the shader programs are
too long. I cannot find any info on how to programmatically check shader
support from the GPU: is Angle limited to pixelshader2, vertexshader2 and
fails on every system, or would it compile ps_3, vs_3 if the graphics card
supports this? Going for Angle was the hope to support simpler/older
hardware, so if there would be a way to support ps_2+vs_2 hardware like
Atom or older Radeon or Intel GMA by utilizing simpler shader programs
(e.g. no ring shadows, normal maps, etc.?) after some tests, there would
be less users having to use super-slow MESA. (But I'm happy at least MESA
is a stable fallback...)

What I still don't know is why my both NVidias on WinXP fail. Both should
support OpenGL3.3.

Kind regards,
Georg
