Background Uploader

This code, if run with a script in background after every iteration of roborumble's client, will upload your result while your client is fighting a new iteration, reducing the iteration time of 25% in the best case.

I'm actually patching roborumble 1.6.0 code to include this script's functionally (simply threading it and modifying the logging system for multi thread) in the hope this will be included in the next official roborumble's client

see after the code for installation instruction

---

ATTENTION: you MUST set roborumble.txt UPLOAD=NOT, ITERATION=NOT, and this code WORKS ONLY FOR 1VS1!!

thank to Rednaxela for code formatting

INSTALLATION copy and compile the code in the robocode home directory(where there is roborumble.bat and roborumble.sh), then if you are windows user create a new file "nameAsYouWant.bat" and write on it (script is not tested!):

:inizio

CALL roborumble.bat

START java UploaderMain
GOTO inizio

if you are under UNIX create a new directory "log" new file "nameAsYouWant.sh" and write on it the following code. This script is more advanced: in the log directory you will find the log of all client's iteration, with at the end the execution time. you can find also 2 log file of the uploader:

1. errUpdaters.txt created and filled with the uploader's error (no error no file)
2. outUploader.txt filled with server response and live time of uploaders
3. results.txt

this last 2 file have to be deleted sometimes

#!/bin/bash
echo
count=0
while [ "$var1" != "fine" ]     #  while test "$var1" != "fine", forever
do
	let "count=count+1"
	date
	echo "battle n: " $count
	time ./roborumble.sh &> ./log/temp$count.txt
	java UploaderMain $count &
	echo
done  

exit 0

WARNING: in the robocode's home directory there will be created a file called results.txt with all unloaded battle; delete it sometimes, with errUpdaters.txt and outUpdaters.txt if you're using unix's script. --lestofante 00:09, 6 December 2008 (UTC)
