Duplicate Waypoints on short waypoint files
The waypoints apperar twice. It is a normal *.cup - File. Exportet from Strepla für LX9000
XCSoar versions having and not having the problem
Having: XCSoar v7.19 (debian) XCSoar7 v.20-Android It's the same behavior an Windows 7.21-PC
Having not: XCSoar 7.18 (debian)
Expected behavior
A waypoint corresponds to a waypoint in the CUP-File
Actual behavior
2 identic waypoints corresponds to 1 waypoint in the CUP-File
Steps to reproduce the behavior
- Load the attached file as the sole file
- Open the waypoint list via for example the guesture
Do you have any idea what may have caused this?
No Idea
Do you have an idea how to solve the issue?
No. Sorry
You did not specify the latest version which does not have the problem.
I'm sorry, I can't quite tell. I always use the latest version of Google Play. I only noticed the error last week when I was creating new waypoint files. At first I thought there was something wrong with the waypoint files. But they seem correct to me. Thanks for your help and especially thanks for the great program. I love it. Can I do something for you? Peter.
So i tested several versions and it seems to be connected to the search short name search feature, introduced in v7.19 https://github.com/XCSoar/XCSoar/commit/9474c3fa972f7a86c3f2c45732e99d62cc9ae378
- This happens with cup files that have field 2 (shortname) defined.
- The particular file here has only few waypoints, so all the waypoints appear without searching.
- You can also trigger it when you use another filter criteria like direction, waypoints with shortname defined appear twice.
- We knew it happens when
Some potential approaches:
- Seperate the name / shortname searches and use different fields in the "Select Waypoiint" Dialog
- Find a way to eliminate duplicates in the radix tree.
I'm also facing same issue when selecting type Landable for example
But not when filtering by distance
I don't know if that's related but removing waypoints file(s) in config and waypoints are still present on the map as if XCSoar was silently loading waypoints whereas I explicitely ask for no waypoints (or there is a kind of cache). Maybe it could explain why they are displayed twice.
