Game Server's Packet to XonStats

<[-z-]> servers send a UDP packet to the stats server
....
<Antares> <[-z-]> servers send a UDP packet to the stats server
<Antares> is this why some matches aren't recorded on XonStats?
<Antares> and if the packet gets dropped or whatever contingency, the protocol doesnt retransmit
....

<[-z-]> Antares: Antibody questions or read the source

Done over UDP or TCP?

Here's how I went about tracing the code, if you're interested.  I still don't have a definite answer for you, but maybe someone can take it from here.

Game code side:

http://xonotic.org/tools/cacs/#0a/0/stats.xon

Code:

grep -R "g_playerstats_gamereport_uri" **/*.qc -B 2                                                                     
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc- });
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc-
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc: if(autocvar_g_playerstats_gamereport_uri != "")
--
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc- PlayerStats_GameReport_DelayMapVote = true;
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc- url_multi_fopen(
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc: autocvar_g_playerstats_gamereport_uri,
--
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc-void PlayerStats_GameReport_Init() // initiated before InitGameplayMode so that scores are added properly
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc-{
data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc: if(autocvar_g_playerstats_gamereport_uri == "") { return; }

Code:

grep -R "url_multi_fopen" **/*.qc                                                                             

data/xonotic-data.pk3dir/qcsrc/common/playerstats.qc: url_multi_fopen(
data/xonotic-data.pk3dir/qcsrc/lib/urllib.qc:void url_multi_fopen(string url, int mode, url_ready_func rdy, entity pass)
data/xonotic-data.pk3dir/qcsrc/lib/urllib.qc: LOG_INFO("url_multi_fopen: need at least one URL\n");
data/xonotic-data.pk3dir/qcsrc/server/weapons/weaponstats.qc: url_multi_fopen(autocvar_sv_weaponstats_file, FILE_APPEND, WeaponStats_ready, NULL);

Code:

grep -R "void url_single_fopen" **/*.qc -n                                                                     
data/xonotic-data.pk3dir/qcsrc/lib/urllib.qc:85:void url_single_fopen(string url, int mode, url_ready_func rdy, entity pass)

XonStat Side:

(accepting a POST request).

Stats are sent over TCP. There is no redundancy, though that would be nice. At best retry logic on the server-side could be implemented.
