I expect that he does. But Nikos has tried writing to the Nikos home 
directory, and to .. (the parent directory). I don't believe he has tried 
writing to . (the current directory), or to /tmp. I'm not an expert, but 
I expect that Apache should be able to write to one of those. And if not, 
he has root on his system, he can simply create a writable directory and 
write to that.

I expect that there are security implications of having a directories 
writable to the webserver user, but temporarily creating one for a quick 
debugging aid should be okay.

This thread follows well travelled grounds from several of the
previous Nikos appearances here.  He seems to have problems grasping
permissions as they relate to apache.  He seems to demand cook book
answers as compared to understanding the issues.  At any rate, isn't
this stuff really something that the Web Server company should be
helping him with?  Its their server, they know how it is configured,
and they can quickly look in his directories to figure out permissions
related issues.

Perhaps. But Nikos is reporting that his log file shows entries from all 
the other websites on the server, which doesn't sound good to me. Surely 
any decent, competent web server company would be able to ensure that 
each customer sees only their own log entries?

No, a normal setup would have that world-readable but not writable.
That way, even if an exploit is found in your web site that lets an
attacker write files, s/he can't upload more files to the web server's
directory and start running them.

A directory writable by the web server might be /tmp.

A simple way I always use if it comes to exception handling:

import sys
import traceback

# Exception Identification
def formatExceptionInfo(maxTBlevel=5):
	cla, exc, trbk = sys.exc_info()
	excName = cla.__name__
	try:
		excArgs = exc.__dict__["args"]
	except KeyError:
		excArgs = "<no args>"
		excTb = traceback.format_tb(trbk, maxTBlevel)
		return (excName, excArgs, excTb)

try:
	# Your code
except:
	print formatExceptionInfo()

Then don't use "tail -F", use "less".

Or try "tail -s 60 -F" which will update only every 60 seconds.

Very nice idea, than k you steven. Less work withiut scrilling like hell liek tail -F did.

this is what i have now:


# Exception Identification 
def formatExceptionInfo(maxTBlevel=5): 
        cla, exc, trbk = sys.exc_info() 
        excName = cla.__name__ 
        try: 
                excArgs = exc.__dict__["args"] 
        except KeyError: 
                excArgs = "<no args>" 
                excTb = traceback.format_tb(trbk, maxTBlevel) 
                return (excName, excArgs, excTb) 

try:
#find the needed counter for the page URL
        if os.path.exists( path + page ) or os.path.exists( cgi_path + page ):
	cur.execute('''SELECT ID FROM counters WHERE url = %s''', page )
	data = cur.fetchone()		#URL is unique, so should only be one
except:
        print( formatExceptionInfo() )

i see no error on what it used ot be isnteait comain at the follwing line which is:

		if not data:
			#first time for page; primary key is automatic, hit is defaulted
			cur.execute('''INSERT INTO counters (url) VALUES (%s)''', page )
			cID = cur.lastrowid        #get the primary key value of the new record 
		else:
			#found the page, save primary key and use it to issue hit UPDATE 
			cID = data[0]
			cur.execute('''UPDATE counters SET hits = hits + 1 WHERE ID = %s''', cID )


i jst dont follow..... What ishsi proposed supposed to give us the error in the query bit now it tells difefrent things.

shoudl i remove the function since it want any helopfull?

You tell us. You want to be a programmer, *you* need to do the 
programming, and not just keep asking others to solve every single bug. 
You have been given all the clues to solve this problem. Start by 
checking what the type of 'page' is, then decide what it ought to be.

Hint: you can use

"print(type(page), file=open('path/to/some/file', 'w'))" 

to see the type of the variable 'page' without displaying it on your 
website.

And what result does form.getvalue return?

What is its type? Is it a list, a tuple, a dict, a bytes object, a float, 
a str object, something else? DON'T GUESS, and don't assume, find out for 
sure, by inspecting the result.

What do you think you need to change it to? Pick one:


1) bytes
2) an integer
3) a string
4) a list of floats
5) something else

In my attemtpt to be shwon only mesages pertaining to superhost.gr i try:

alias err='tail -F /usr/local/apache/logs/error_log | grep nikos &'

but now it only displays to me the lines that have '/home/nikos' within them and not all the relevant error lines.

Then pick a different location, one where you have permission to write 
files!

Honestly Nikos, I'm not trying to be rude, but if you cannot think of 
this on your own after all this time we've been helping you, perhaps 
programming is not the right vocation for you. Perhaps you need to 
consider a change of career.

If you do decide to stay as a web developer, you need to start thinking:

* What is this error message telling me? ("Permission denied")

* How can I fix that? ("I need permission to read the file. Maybe try a 
different file?")

That's an apache logging issue, not Python, and I don't know enough about 
apache to do more than guess that there probably is a solution but I have 
no idea what it is.

If you type filenames as carelessly as you type requests for help, who 
knows what file name you are actually trying to open?

Or to put it another way...

If yuo tpye filnaems as carlesl yas y outype reqets for help, woh knwos 
wha tfile nmae oyu ar eactaly tying to oep n?


Nikos, my Greek is completely non-existent, and I admire you for learning 
a second language. I know your English is good, because I have seen you 
write fluent, excellent English. But if you can't be bothered to type 
carefully and clearly when asking questions, then how can you expect 
others to be bothered to read and respond to your questions?


> if you as experts cannot help resolve this, how me as a newbiw can?

Just because your account has write permission to a location doesn't mean 
that the script being run by the webserver has write permission. You need 
to write to a location where the script has permission to write. First 
you need to find out what account the script is being run under -- it may 
be "apache", or possible "nobody", but I don't know. It shouldn't be 
"root", and almost certainly isn't "nikos". I'm not an expert, but a few 
seconds googling came up with a lot of useful looking hits. Google on 
"what user does apache run as" and do your research.

This is off-topic though. This is not a "beginner's guide to apache" 
forum, if you can't solve this problem yourself you'll have to take it 
elsewhere.

Hi steven , sorry for the typos.

you are write my script is invoked by apache web server application which it runs under account 'nobody'

Here is proof of that:

I see that your apology for careless writing didn't last very long.

What is the value of "e" here, and where is it defined?

Let's look at the error in your log file:

Did you bother to read the error before asking for help?

Variable 'e' is not defined. Perhaps you should define it?

Yes indeed , that was a a syntax error by me:

try:
    #find the needed counter for the page URL
    if os.path.exists( path + page ) or os.path.exists( cgi_path + page ):
    cur.execute('''SELECT ID FROM counters WHERE url = %s''', page )
    data = cur.fetchone()        #URL is unique, so should only be one
except Exception as e:
        con.rollback()        #something failed, rollback the entire transaction
        print( repr(e) )

outputs:

Now at least 'superhost.gr' displays the error when one by browser http://superhost.gr

Oh look, it's exactly the same error you started with. Congratulations, 
you've made exactly no progress. As I asked you yesterday:

    And what result does form.getvalue return?

    What is its type? Is it a list, a tuple, a dict, a bytes object,
    a float, a str object, something else?


Have you worked that out yet? If you can't work it out, you can guess, 
and then test your guess:


page = form.getvalue('page')
if isinstance(page, list):
     raise TypeError('guessed it was a list, it is a list')


If your guess is wrong, try another guess. Keep going until you work out 
what type page is.

If you can't write to a data file, you can write to the error log:


page = form.getvalue('page')
raise TypeError('type of page is %r' % type(page))


Keep going until you find out what type of data the variable 'page' is 
holding. Now read the error message again:

unsupported operand type(s) for %: 'bytes' and 'str'


Do you understand what that error means? Here is a hint: start a Python 
interactive session, and try things for yourself:


steve@runes:~$ python3.3
Python 3.3.0rc3 (default, Sep 27 2012, 18:31:58) 
[GCC 4.4.5] on linux
Type "help", "copyright", "credits" or "license" for more information.
py>
py> 'string%s' % 'string'
'stringstring'
py> 
py> b'bytes%s' % b'bytes'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for %: 'bytes' and 'bytes'


Do you see a pattern yet? What do you think will happen if you run this?


b'bytes%s' % 'string'


Try it and see for yourself.


Now look at the error message you are getting. Is it the same error 
message? Do you think that perhaps it has the same cause? How do you 
think you might solve this problem?

Hint: if you have a data item that is type A, and you need it to be type 
B, you need to convert from A to B.
