tilelite demo issue

[kalxas]

I am getting pink tiles in Mapnik & Tilelite demo page (as described in Quickstart). To reproduce this:

1. Use 6.0beta1
2. Reinstall mapnik using #sudo ~/gisvm/bin/install_mapnik.sh
3. Start Maptile
4. Visit ​http://localhost/mapnik/openlayers.html

correction: step 3: Start Mapnik & Tilelite

still here in beta2

mapnik is confirmed to be working by Hamish. This is just a demo problem.

I get a Google API key error. I can go to the OSM tiles from the openlayers menu in the top-right "(+", but no population demo there.

we need to attract more attention to this...

Hi,

If I scroll back in the debug terminal I notice this, with a Broken Pipe:

...

the tilelite files to look at are:

/usr/local/bin/liteserv.py /usr/local/lib/python2.7/dist-packages/tilelite.py

also, I can't see where the .py to set the Google API key. (e.g. a personal one for testing)

Google has disabled use of the Maps API for this application. The
provided key is not a valid Google API Key, or it is not authorized
for the Google Maps Javascript API v2 on this site. If you are the
owner of this application, you can learn about obtaining a valid
key here: http://code.google.com/apis/maps/documentation/javascript/v2/introduction.html#Obtaining_Key

?

thanks, Hamish

FYI: The "Bropen Pipe" errors are ok. That happens when the client (browser) requests a tile and closes the connection before the tile was completely transfered (e.g. the user zoomed in and the tile is no longer needed).

Replying to olt:

ah, ok, that's probably that then.

so how then to debug it? I don't see anything in any of the usual /var/log files.

thanks, Hamish

So the issue is with the Javascript. Basically it was calling the tiles as an OSM source, I switched it to an XYZ, since the latest openlayers treats that differently. I also pointed the sample to the local installs of OL and Jquery so the demo works 100% offline. See app-conf/mapnik/local.html

Fix committed, docs url updated to local.html. Can someone please verify and then close this ticket.

Thanks Alex for the fix. We will confirm in next build and close this.

fix confirmed in beta5
