[bug] flexo serves 0 length files about flexo

[nroi]

Flexo obviously shouldn't create empty files and then assume that 0 is the correct content length, so this is a bug.

Another problem is that, for some reason, the selected mirrors are causing timeouts for you. Could you please tell me if:

• You are located at or near central Europe? Because if you're located at another continent, then there seems to be a problem with the mirror selection process, because the selected mirrors are in Germany.
• Do you generally have a bad or high latency internet connection? Are you using a VPN, or a wireless 3G connection or anything out of the ordinary that could introduce latencies?

As a workaround:

1. Remove all empty files (something like find /var/cache/flexo/pkg -size 0 -print -delete should do the trick.
2. It looks like you currently have the setting mirrors_random_or_sort = "random", try to change this to mirrors_random_or_sort = "sort", because the random setting has not been tested as well as sort.
3. Remove the latency test results and restart Flexo so that the latency test is started again:

   rm /var/cache/flexo/state/latency_test_results.json
   systemctl restart flexo
   

Any idea how to increase the downlaod time out as workaround?

Flexo is currently using the default timeouts from CURL, and so far, I think they have worked well for all users. So I hope we find a solution where fast mirrors are selected so that no timeouts occur.

Thanks for the reply. About the repo, yes I am in Central Europe. My internet is OK but I seems to have some issues with some of the German servers. I have to blacklist the ones that are causing me problem. The issues with those servers was happening even when I was using nginx caching server.
