[But] Slow internet connection causes export to truncate gpx file

[christaikobo]

Describe the bug
Basically when connecting using a slow internet connection and trying to export, I got a partial file.

It should be 75MB, but I got 3 MB file, and it was truncated. Something like this:

<?xml version="1.0" encoding="UTF-8"?>
<gpx version="1.1" creator="Reitti" xmlns="http://www.topografix.com/GPX/1/1">
  <metadata>

Hi @christaikobo,

is there something about a dropped/reset connection in the logs.

I am not sure what we can do here, reitti tries to stream the gpx file to your browser when downloading it. We do not want to load all points at once in memory, for larger exports this will kill the server. If the connection is cut in the middle, there is no way of sending that data then to the client.

I am able to download file through other HTTP source normally, even though the internet is not very fast. I am not sure how the file streaming in reitti is handled though.

I will have a look what can be done from our side here. But with low priority, i first want to get the new release out.

So, lets keep this open as a reminder for me
