TopoFusion News

Got a new version out that fixes a bug that has been quite mysterious. If anyone out there has done much multi-threaded programming, you know how random certain problems can be. In this case I could not reproduce the problem on my main development machine no matter how hard I tried, and despite near daily use of the software (Yes, I am still the primary user of TopoFusion — use it all the time).

Finally, it started occurring, for unknown reasons, while using the WiFi at the Salida Public Library. From there, the game was afoot!

The error cropped up with an “SSL refcount error” then oftentimes a crash in the Downloader Thread. Turns out the documentation on the OpenSSL library is pretty lacking, but I believe the bug is vanquished! Cheers! Applause!

Also restored in this version are OpenTopoMaps, Juicy Trails and Open Cycle Maps.

I’ve finally given up on (formerly Terraserver) coming back online. That was the server that got TopoFusion off the ground, but it seems at last to be dead. RIP Terraserver, thanks for all the many maps and adventures!

As a result, the software has been simplified to remove those tilesets so as to not cause confusion to new users. If you have a bunch of those maps cached, they’ll still work, but you may need to enable by editing the TopoFusion.ini file and changing UseMSRMaps=0 to UseMSRMaps=1

Update your TF and check out the new version (full list of changes below), or if you are new to TopoFusion, go ahead and try the demo. And as always, let us know what you think, especially if you have a suggestion for a new feature or different way the software should work.
