Detail Issue Notes
blocking issue between Rismo's code and ROL locks
Description: The issue with Rismo's code is that he had pushed ROL deletes into a list that were then handled on the main (gui) thread. But you need to do this for both adds and deletes because you can end up with blocking for either one.
The problem then was things in WW and plugins assumed that an add or delete happened immediately so you'd end up with breakage because somethings avoided using the getters and setters but hit the ROL array directly. They would do an ROL.add(...) then try to get at those objects immediately and they weren't there. Or they'd do an ROL.remove(...) and maybe do a dispose on it or something else not nice. So when you got around to handling deletes the object was bad or in some not good state.
The breakage can be pretty obvious (crash) or somewhat more subtle (ROs don't render or behave right).

Download code error response handling
Description: Download code will download repeatedly request tiles after a error response code from the server, e.g. 400,404. World Wind will also not handle 500 or other server error responses with appropriate time-out behavior.

Comments: (ammianus) - 7/26/09 - I've made some changes and tested with the help of James_in_Utah. The changes I made include:
- 4xx / Client error are cached as failures and WW will not retry to download them during that session (cache is in memory only and cleared when WW is exited).
- 400 Bad Request
- 401 Unauthorized
- 403 Forbidden
- 404 Not Found
- 206 Partial Content
- 200 OK && Content length == 0
- 5xx / Server Error are recorded and a timeout period will begin before requests are allowed to this server again. A message is displayed in the top right of the UI stating the timeout length. If server response contains "retry-after" header, that period is used, otherwise default is 2 minutes.
- 500 Internal Server Error
- 501 Not Implemented
- 502 Bad Gateway
- 503 Service Unavailable
Changes made to source files:
- WebDownload/WebDownload.cs
- PluginSDK/QuadTileSet.cs
- PluginSDK/Renderable/GeoSpatialDownloadRequest.cs

starfield listed in layer manager is the older plugin
Description: when you uncheck "Starfield" in the Layer Manager, it doesn't actually remove the stars that are in the background.
Forum Threads: N/A
Comments: The Starfield issue isn't exactly a bug, the starfield listed in layer manager is the older plugin and probably isn't actually needed, the other starfield is Stars3D
WWC to support WWJ cache location and files
Description: WWC (.NET) should be changed to accept data from the cache WITHOUT the leading "00".
Both the WWC and WWJ (and most other) servers do not have the leading "00". There is no reason a WWC layer cannot be made to download from the WWJ server.
Default cache location changed to match the Java. Vista has a Program Data folder in the C drive, just like Program Files, that should do the trick for storing the cache (in fact this is where WWJava stores it cache on Vista) and then there are AppData folders in the user folders that could store the config files and possibly some plug-ins (the World settings and World Wind settings files are already stored in this AppData folder, along with the debug reports C:\Users\<user>\AppData\Roaming\NASA\World Wind)
