If you're code is correct, then use it and be happy.

There's no need to bother us if your code is correct.



Could this be an extremely rare case whereby the original code is 100%

Jests and barbs left aside, I believe his definition of correct is
wasn't crashing. Earlier in this thread there was a hint that he'd
tightened a bare except to one specific exception. My guess is his
code wasn't correct, but one bug (overly-broad try/except) masked
another.

You may like porgramming, but it is rather obvious you don't like
the python style of programming. So maybe you should chose a
laguage whose style is more to your liking.


Perhaps it would be even better if you quit spamming my thread with your

You have no authority over what people contribute in your thread. Since
you don't seem very considerate about the effect your contributions have
on others, you can hardly expect others to be considerate of you.

Several method have been given to solve the problem.

Your ironic attitude on the other hand is what characterizes you.

Triing out various solutions and picking the one that better meets one's

Well aside from the fact that you've maintained your record by being 
inaccurate with 50% of the names that you've quoted, it appears that 
we've something that has very much in common with your website.  Which 
reminds me, is it still possible to access your users' names and

 I learn Python for personal pleasure because i like programming.
 Perhaps it would be even better if you quit spamming my thread with your
 funny quotes.

Then maybe you should keep to programming for personal pleasure and
stop trying to make it part of your business. Most of your problems
stem from a perceived urgency - you panic, because you have stupidly
edited your live code again, and come to this list begging for help.
If you were coding purely for pleasure, your problems would not lose
you customers, and you could deal with issues calmly.

To be quite frank, I think you SHOULD lose customers. Suppose you buy
a piece of furniture from some small-time carpenter, and the moving
parts are stuck, it wobbles on its legs, and if anyone uses it who
isn't American, it crashes to the floor (which is how your Unicode
issues make you look). You go and complain, loudly, in front of people
who were looking at his wares and considering buying. He might lose
customers because of your complaint - but if he's selling a dodgy
product, he *should* lose customers. Carpentry for pleasure, or
programming for pleasure, is a fine thing to do, but it should not be
considered business.

Nikos, I sincerely hope that all these problems cause you to go out of
business. Preferably right now, with just enough maintenance to last
till the end of your contracts with people. Then start programming
purely as a hobby, until you actually master the craft.

Well aside from the fact that you've maintained your record by being
inaccurate with 50% of the names that you've quoted, it appears that
we've something that has very much in common with your website.  Which
reminds me, is it still possible to access your users' names and
passwords in plain text or is that something that you've actually

Nope, it isn't. I have fixed it.

Absolutely hilarious.  Please give up your web work and Python and get a

I learn Python for personal pleasure because i like programming.
Perhaps it would be even better if you quit spamming my thread with your
funny quotes.


Then maybe you should keep to programming for personal pleasure and
stop trying to make it part of your business. Most of your problems
stem from a perceived urgency - you panic, because you have stupidly
edited your live code again, and come to this list begging for help.
If you were coding purely for pleasure, your problems would not lose
you customers, and you could deal with issues calmly.

To be quite frank, I think you SHOULD lose customers. Suppose you buy
a piece of furniture from some small-time carpenter, and the moving
parts are stuck, it wobbles on its legs, and if anyone uses it who
isn't American, it crashes to the floor (which is how your Unicode
issues make you look). You go and complain, loudly, in front of people
who were looking at his wares and considering buying. He might lose
customers because of your complaint - but if he's selling a dodgy
product, he *should* lose customers. Carpentry for pleasure, or
programming for pleasure, is a fine thing to do, but it should not be
considered business.

Nikos, I sincerely hope that all these problems cause you to go out of
business. Preferably right now, with just enough maintenance to last
till the end of your contracts with people. Then start programming
purely as a hobby, until you actually master the craft.



I learn during the process.
That's how i deal with the situation.
I challedge my self and then try to confront the given situation _live_.

It's not wise to do so, but that how i operate.
Apart form that my customer's webistes have no problems, everyhting i do 
its domain specific, my domain, DNS and Mail issues for my domain, i 
don't play with customer's settings and data.


I have a good sense _not_ to fiddle with their accounts(except from the 
time that i have taken the risk to give you root access to helo me with 
a python issue, and you've helped me appropiately).

This is a sentiment I can heartily endorse. Far better than puerile
jeers and hostile desires for violence.

Please, everyone in this thread needs to keep in mind our host's
Diversity Statement:

The Python Software Foundation and the global Python community
welcome and encourage participation by everyone. Our community is
based on mutual respect, tolerance, and encouragement, and we are
working to help each other live up to these principles. We want our

And this doesn't bother you???!?

Nikos, industry best practice is to make sure people can't steal all
your users' passwords *even if they get access to your hard drive*.
Passwords should be stored like this:

92e25cf5beefd4982cedd2f28b430e0e9d23e0966ee3f20c74f825eb9842

That's the password qwer, on an account named asdf, on a mythical
system. Even knowing that, you can't work out what another password
means. Storing people's passwords in plain text is a HORRIBLE HORRIBLE
idea - and having them accessible to the world is a sign of a complete
and utter lack of any semblance of security.

I understand that bugs happen. But bugs of this criticality should be
your very highest priority... unless you're not actually in business
here, and you're just scamming a bunch of people by pretending you run
a legit enterprise.

I don't have the security awareness you have, but i'am learnign at the

What maked you think i store peoples password in plain text?

All the user account passwords i set i do it via cPanel or via WHM.

How those services store the password in the linux server its up to them.

Everyone's learning on the job. (I learned this week that it's
possible to play fast and loose with ARP and routing, to make one
computer look like two and two look like one. That was fun. When I
came up with the concept, I gave my boss a 95% confidence that it'd
work; and so far it's not caused any trouble.) But what you're doing
is charging your customers while you learn the very basics. You can't
sell Hello, world. Most people expect to go to university to learn a
trade; some spend two decades playing with something before earning a
single dollar (or Euro, or yen).

Learn to code, THEN try to make money at it. Or even leave off the
'then' clause - plenty of people never earn anything from code, and
stay as happy amateurs. There's nothing wrong with that.

I designed their websites and they are up and running.
Yes i have charged some money, but they gain what they paid for, a

So, its not like i'm ripping off someone here.


You can't sell Hello, world.


I hope i was in the position to sell python code but i'am not.
I learn Python because i like programming.

My reseller site should have been made probably in wordpress or joomla 
cms but i decided to code it in Python instead because i like the 
language and want it to learn it better and better. It has secret 
functions as well.


When i problem occurs i just ask and thats how i progress.
Sometimes i do a little reading too :)

Something's trying to decode a stream of bytes as UTF-8, and it's not
UTF-8. Work out what in your code is bytes and what is strings, and do
your own conversions.

okey i will, but isnt this just weird:

How come all these daysthe followinf line work as expected:

host = socket.gethostbyaddr( ipval ) [0]

and only just today just happened to output:

Nothign got added in my script. This is the only line that tried to

The snippet is this:

ipval = ( os.environ.get('HTTP_CF_CONNECTING_IP') or 
os.environ.get('REMOTE_ADDR', Cannot Resolve) )

city = Άγνωστη Πόλη
host = Άγνωστη Προέλευση
try:

ipval is suposed to get just an ip address.
ip addresses doesnt change its just number seperated by dots.
the same provider i uses yesterday i continue to use today, i just 
restrated the router and got a new ip address and after the new address 
got assignes to me.


unicode decore error related to host started to happen.
Can someone explain this or have a way to troubleshoot it because this 
error is bugging me for several months now but not all the time just in 
cases liek miens today.

But the error comes from:

.^^


Given that the error occurred hours ago, I don't think you'll be able to 
diagnose why it happened unless it happens again.


Another thought comes to mind... unless you have changed your habits, I 
recall that you edit the source code live. If that is the case, it is 
possible that the error actually occurred in a completely unrelated line, 
if you happened to be editing the file at the moment the error occurred.

That's one way an IP address can be rendered. It's not the only one.
There's an entire category of IP addresses that's usually written with
colons rather than dots. However, I reiterate: How do you KNOW what's
in ipval? I wonder if there's an easy way for you to find out...

ChrisA


yes it is, i take it you mean to just print the damn varibale to see
what on eath is actually outputs back



Here, as exactly as i though of it:

print( ipval )  returned  46.198.177.249

^^

But the error comes from:


[Sun Sep 29 07:44:43 2013] [error] [client 173.245.49.126]

.^^


Given that the error occurred hours ago, I don't think you'll be able to
diagnose why it happened unless it happens again.


Another thought comes to mind... unless you have changed your habits, I
recall that you edit the source code live. If that is the case, it is
possible that the error actually occurred in a completely unrelated line,
if you happened to be editing the file at the moment the error occurred.


You remembr correctly, i'am still editing the source code live to 
reflect instant changes.


Butat that moment and all mornign long i wasnt altering the code at 
all when this error occured and i just tried it at the moment as iam 
typing it this by alterting the


except Exception as e: === except socket.gaierror as e:
which cannot handle unicore realted errors and the exact same error 
appeared with my ip address involved at the error log.


so, the question that arises again and reamins is how come 'host' vars 
gets a values most of the times and sometimes it just outputs back 
unicode related erros.


I must tell you that i had this problem also months ago, but since i 
couldnt able to solve it i left it as it was, but it just started to

Something's trying to decode a stream of bytes as UTF-8, and it's not
UTF-8. Work out what in your code is bytes and what is strings, and do
your own conversions.

http://www.joelonsoftware.com/articles/Unicode.html

READ IT. Do not write another line of code until you actually
understand what he's saying there.

ChrisA


okey i will, but isnt this just weird:

How come all these daysthe followinf line work as expected:

host = socket.gethostbyaddr( ipval ) [0]

and only just today just happened to output:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 0:
invalid start byte erros?

Nothign got added in my script. This is the only line that tried to 
determine the host.


This is the nature of Unicode pain in Python 2 (Python 3 has a different 
kind!).  This may help you understand what's going on:

it would be interesting to see a more complete stack trace.  But I'd
guess that in the process of looking up the ip address at the dns
servers, somebody is producing a non-ascii byte string that isn't
encoded in utf-8.  It might conceivably be in your /etc/hosts file as
well, assuming gethostbyname() looks there when the internet query

This can cause problems
Do i need to chnage the mx record in cloudflare so mx records point to 
somethign else being ???


Also my webpage works as

www.superhost.gr   but not as superhost.gr

I have removed my webiste from cloulflare to make thigns simpler and now 
in order to viw mywebiste i must give

http://www.superhost.gr

if i give plain http://superhost.gr it doesnt load at all.

The only way is http://www.superhost.gr but no link on my webpage works 
when clicked upon.


iam getting this: http://superhost.gr/cgi-sys/defaultwebpage.cgi

Clearly these are DNS and Mail issues.

i have asked PaulVPS which is my provider and they dont f* care to

I can point you to “find a sysadmin that will work for you and fix

To be more specific: Greek job-posting web sites. Or maybe general
job-posting web sites will let you search specifically for people who
speak Greek. Either way, you're looking for someone to hire, here.
Maybe you want a contract position, or maybe salaried, but either way,

Two options: Either edit your bind file manually OR use some other

mailIN  CNAME   @
www IN  CNAME   @
ftp IN  CNAME   @
-- cut --

The changes I've made are:
1) Remove the massive duplication of your domain name, mainly by using
the shorthand @. (There are other shorthands you can use, too.)
2) Remove the dot from your email address. Currently your official
address is ni...@gr33k.gmail.com which is flat-out wrong. Fortunately
for you, Gmail will accept nikosgr...@gmail.com no problem.
3) Eliding the TTLs where they're the same as your default
4) Removing the entry for localhost.superhost.gr which you shouldn't
really be using - it'll only confuse matters. Use localhost as a TLD -
that's how it's set up.

Aside from #2 and #4, this shouldn't actually change your DNS records,
but it'll make your bindfile that much easier to read and work with.

Of course, if you're editing the file with some other program, don't
do this at all. Just use that other program.

i dont ebven have access to cPanel and WHM any more by hostname.

The via WHM i have reset the DNS Zone for superhost.gr and let it 
recreate it as WHM wants it by default.


Still same error. No website appearing anymore no access to cPanel  WHM

This is really excellent and I bookmarked it.

There is one minor error: the conversion from int to float can't fail,

 float(10**1000)
Traceback (most recent call last):
  File pyshell#0, line 1, in module
float(10**1000)
OverflowError: long int too large to convert to float

Even when it succeeds, it can fail in the sense of losing information.

12345678901234567168
 float(int(1.55))
1.0

This is somewhat analogous to a combination of errors='ignore' and 
errors='replace' (with random garbage).


I think the presentation would be strengthened with the correction, as 
it shows that the problems of conversion are *not* unique to bytes and

Yes it is a key, but the problem as i suspected was cloudflare.
i had to use os.environ['HTTP_CF_CONNECTING_IP'] that cloudflare passes 
as variable i the cgi enviroment in order to retrieve the visitor's ip.



try:
gi = pygeoip.GeoIP('/usr/local/share/GeoLiteCity.dat')
city = gi.time_zone_by_addr( os.environ['HTTP_CF_CONNECTING_IP'] )
host = socket.gethostbyaddr( os.environ['HTTP_CF_CONNECTING_IP'] )[0]
except Exception as e:
host = repr(e)


Sometimes though iam still receiving the usual
UnicodeDecodeError('utf-8', b'\xc1\xf0\xef\xf4\xf5

but only for a few ip addresses, in moste cases it works.

What do you mean I don't know how to catch the exception with

try:

except OSError:

produces also an internal server error.

Are you sure is just except OSError ?



Have you ensured that 'REMOTE_ADDR' is actually a key in os.environ? I
highly recommend using the logging module to help diagnose what the
actual exception is.

HTH,

Yes it is a key, but the problem as i suspected was cloudflare.
i had to use os.environ['HTTP_CF_CONNECTING_IP'] that cloudflare passes
as variable i the cgi enviroment in order to retrieve the visitor's ip.


try:
 gi = pygeoip.GeoIP('/usr/local/share/GeoLiteCity.dat')
 city = gi.time_zone_by_addr( os.environ['HTTP_CF_CONNECTING_IP'] )
 host = socket.gethostbyaddr( os.environ['HTTP_CF_CONNECTING_IP'] )[0]
except Exception as e:
 host = repr(e)


Sometimes though iam still receiving the usual
UnicodeDecodeError('utf-8', b'\xc1\xf0\xef\xf4\xf5

but only for a few ip addresses, in moste cases it works.


And naturally, you now know how to debug those UnicodeDecodeError 
problems.  Surely, the code you post here isn't what you actually do, 
because when people spend time to give you detailed advice, you actually 
read it, and work at understanding it.

I see, but if the function returns a byte string not inutf-8 format then 
how my script is uspposes to decode this byte string?


And why only this error happens when i cloudflare my domain, while when 
i un-cloudflare it are reverse DNS are being resolves without problem.

So the queston is: How come it only fails when i cloidflare the domain?

Also please comment on that:

host =  gethostbyaddr() or UnResolved

This will return the first argument that define the evaluation as being 
true or untrue.


if function returns false the the 2nd argument.
Nut if the function gives an exception will the condition return the 2nd 
argument or will the program fail?


I was udner the impression that i could avoid error handling  inside

Names obtained from DNS should consist entirely of ASCII characters
(gethostbyname shouldn't attempt to decode internationalised names
which use IDN, it should return the raw data).

Names obtained by other means (e.g. /etc/hosts or Active Directory) could
contain anything, but if you use non-ASCII hostnames you're asking for
trouble.



Please help because i just happened to noticed that after having this code:

Thank you Lele, i wanted to but i had no idea how to test it.
Your devision by zero is very smart thing to test!

So it proves that a condition cannot be evaluation as truthy or falsey 
if one of the operators is giving out an exception.

Thank you.

They aren't equivalent. except Exception won't catch KeyboardInterrupt or
SystemExit or a few others that you really don't want to catch in a generic
error handler. You should almost never have a bare except.

Don't ever catch a bare Exception class.  Make it more specific to the 
particular problem you're trying to suppress.


In particular, your previous problem with the utf-8 decoding will also 
be caught by the Exception class, so it'll get all lumped together as 
Reverse DNS Failed.





all requests are being resolves, result to:


Reverse DNS Failed as you can see here:
http://superhost.gr/?show=logpage=index.html

Since you've not made any progress with all the other suggestions, how 
about if you decompose this line into several, and see just which one is 
failing?  Maybe that'll tell you what's going on.  In general, 
suppressing an exception without knowing why it's firing is a huge mistake.


The line started as:

  host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]

refactor that to:
   remadd = os.environ('REMOVE_ADDR')
   tuple3 = socket.gethostbyaddr(remadd)
   host = tuple3[0]

and see which one throws the exception.  Then once you have that, 
examine the exact parameters that might be triggering the problem.  In 
particular, figure out the exact types and values for remadd and tuple3.


   print(type(remadd) +  :  + repr(remadd))

Of course, print itself won't work too well in a CGI environment.  But 
you must have solved that problem by now, either using log files or 
running the program excerpt in a regular console.

How have you been doing it all along?  Just open a console onto that 
server, start the appropriate version of Python interactively, and try 
the things we've been talking about.  If it fails the same way as within 
the cgi environmnet, you get full visibility.


Or if the problems cannot be recreated outside the cgi environment, use 
the log files you've been logging other problems into.  Or simply open a 
text file for writing, and add a file= keyword parameter to the print 
function call.


 print(repr(e), file=myfile)

I have no idea what causes an internal server error.  It's up to you to 
get the output of the expression to some location you can examine. 
Easiest way is to run those 3 lines directly on the server, not in the 
cgi environment.


But if you don't have any debugging tools, then STOP right now and build 
some.  Use logging, or redirect print, or do something that the server 
folks provide as debugging aids.  But just blindly guessing is 
ludicrous.  So also is throwing out clues by using a bare except.


Assigning that string to host makes no sense at all.  And neither does 
putting it in the except clause.  You want to get that string to YOUR 
eyes, not to the server who might get an internal server error.

Any thoufgs as to why os.environ('REMOTE_ADDR') gives the above error?

I noticed that if i remove my domain from cloudflare the gethostbyaddr 
as it uses too months now.

Wait!
Are you saying that the ip address is being returned as a byte string 
which then i have to decode with something like:


host = socket.gethostbyaddr( os.environ['REMOTE_HOST'].decode('utf-8') )[0]

?

Yes, I'd try to understand the error message, and eventually lookup the
documentation on os.environ to see what type of object it is bound
to. The solution should be easy.

Looks now when i print( repr(e)) i get

UnicodeDecodeError('utf-8', b'\xb6\xe3\xed\xf9\xf3

but what string does it try to decode and jeeps failing?

Reasonably it's the second one, as the first clearly seems the tag of
the decoder that tried to translate it to Unicode.

As already explained, your immediate goal should be trying to understand
from *where* that byte string is coming. I can't help on that, sorry.

2nd one of what? 2nd byte in order?
Can ou show me form which characters does this string consist of so we 
migth have an idea of where its coming from if we know what it looks like?

Thats what i'm trying to do.
If i completely remove the gethostbyaddr fucntion adds function then 
there is nor problem.


The problem is recreating when the script tries to decode a hostname.

For some bizarre reason if i exclude my domain from CloudFlare then the 
reverse DNS resolution of the visitors hostname would be returned properly.


I will do it right now for you to see.

You asked “what string” (although you probably meant “which string”):

UnicodeDecodeError('utf-8', b'\xb6\xe3\xed\xf9\xf3

first string---^^^
second string---^^

Precisely as i have said it would happen:

I removed the domain form CloudFlare and your domains visting my website 
appearing as usual.


Its only when i cloudflare it and the UnicodeError happens.

But why?!?! I see no reason as to why when my domain becomes Cloudflared 
the gethostbyaddr() fails.


What kind of weird strings does it return back?

Hold on please!

From where do these dashes and carets characters come from?
Also from where do you see 2 strings?

Looking at that: UnicodeDecodeError('utf-8', b'\xb6\xe3\xed\xf9\xf3

ic an understandn onlt that utf-8 has failsed decoding some byte stream 
satrting with \xb6


I totally not follow...

Wait!
I get a decode error when python tries to automatically decode a bytestring 
assuming it to be utf-8 encoded.
I am sure the error will disappear, when I try to decode it explicit using 
utf-8. Heureka! I got it!

Or in other words:
If a big stone falls on my foot accidently it hurts.
But I am sure it will not hurt, if take that same stone and throw it on my foot.
Heureka! I got it!

ROTFL
Nikos, you made my day, again! Fun is back in these threads!

 
 Also from where do you see 2 strings?

Look, my little dumb baby: The dashes and carets point to the strings.
The first one being 'utf-8', the second one starting with '\xb6\xe3\xed' (being 
a bytestring, therefore the b before the ')
Sorry, I forgot. You are not using python for your business, therefore you 
can't know, that strings in python can for example be identified by surrounding 
'.

 ic an understandn onlt that utf-8 has failsed decoding some byte stream 
 satrting with \xb6
So ... where did you call utf-8() so that it could try to decode something?
