Suddenly my webiste superhost.gr running my main python script presents
me with this error:
Code:
UnicodeDecodeError('utf-8', b'\xb6\xe3\xed\xf9\xf3\xf4\xef
\xfc\xed\xef\xec\xe1 \xf3\xf5\xf3\xf4\xde\xec\xe1\xf4\xef\xf2', 0, 1,
'invalid start byte')
Does anyone know what this means?

Webhost <http://superhost.gr>
Good morning Steven,
Ye i'm aware that i need to define variables before i try to make use of
them. I have study all of your examples and then re-view my code and i
can *assure* you that the line statement that tied to set the 'host'
variable is very early at the top of the script(of course after
imports), and the cur.execute comes after.
The problem here is not what you say, that i try to drink k a coffee
before actually making one first but rather than i cannot drink the
coffee although i know *i have tried* to make one first.
i will upload the code for you to prove my sayings at pastebin.

You are mistaken. In line 20-25, you have this:
try:
gi = pygeoip.GeoIP('/usr/local/share/GeoIPCity.dat')
city = gi.time_zone_by_addr( os.environ['REMOTE_ADDR'] ) or
gi.time_zone_by_addr( os.environ['HTTP_CF_CONNECTING_IP'] )
host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0] or
socket.gethostbyaddr( os.environ['HTTP_CF_CONNECTING_IP'] )[0]
or "Proxy Detected"
except Exception as e:
print( repr(e), file=open( '/tmp/err.out', 'w' ) )
An error occurs inside that block, *before* host gets set. Who knows what
the error is? You have access to the err.out file, but apparently you
aren't reading it to find out.
Then, 110 lines later, at line 135, you try to access the value of "host"
that never got set.
Your job is to read the error in /tmp/err.out, see what is failing, and
fix it.
But i'm Steven! That why i make use of it to read it immediately after
my script run at browser time.
i have even included a sys.exit(0) after the try:/except block:
Here is it:
errout = open( '/tmp/err.out', 'w' ) # opens and truncates the
error output file
try:
gi = pygeoip.GeoIP('/usr/local/share/GeoIPCity.dat')
city = gi.time_zone_by_addr( os.environ['REMOTE_ADDR'] ) or
gi.time_zone_by_addr( os.environ['HTTP_CF_CONNECTING_IP'] )
host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0] or
socket.gethostbyaddr( os.environ['HTTP_CF_CONNECTING_IP'] )[0] or "Proxy
Detected"
except Exception as e:
print( "Xyzzy exception-", repr( sys.exc_info() ), file=errout )
errout.flush()
sys.exit(0)
and the output of error file is:
ni...@superhost.gr [~]# cat /tmp/err.out
UnicodeDecodeError('utf-8', b'\xb6\xe3\xed\xf9\xf3\xf4\xef
\xfc\xed\xef\xec\xe1 \xf3\xf5\xf3\xf4\xde\xec\xe1\xf4\xef\xf2', 0, 1,
'invalid start byte')
But i noticed that err.out and /usr/local/apache/logs/error_log produced
different output.
In any case i check both:
ni...@superhost.gr [~]# chmod 777 /tmp/err2.out
ouput of error_log
ni...@superhost.gr [~]# [Sun Sep 01 14:23:46 2013] [error] [client
173.245.49.120] Premature end of script headers: metrites.py
[Sun Sep 01 14:23:46 2013] [error] [client 173.245.49.120] File does not
exist: /home/nikos/public_html/500.shtml
Also i have even changed output error filename.
turns out empty.
ni...@superhost.gr [~]# cat /tmp/err2.out
