Okey it was the python path (shebang that was causing this)

Now i have correct it from

/usr/local/bin/python3 => /usr/bin/python
System has beens etup this way to point directly to python 3.3.2 in the
new VPS.
Admin setit up that way hwile in the old one was different.

But i cannot overocme thjis:

So, in this line:

cur.execute('''SELECT ID FROM counters WHERE url = %s''', page )

the variable 'page' needs conversion to what?

all that is stores is the location of a file

path = '/home/nikos/public_html/'

page = form.getvalue('page')

if not page and os.path.exists( file ):
# it is an html template
page = file.replace( path, '' )

So chnage it to what?

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.

all that is stores is the location of a file

path = '/home/nikos/public_html/'
page = form.getvalue('page')

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.

if not page and os.path.exists( file ):
# it is an html template
page = file.replace( path, '' )

So chnage it to what?

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

 

[Dennis Lee Bieber]

someone please?

You waited only 30 minutes before bumping the thread?...

Consider that your time zone is 8 hours ahead of mine, your post came
in an hour after I went to work. The earliest I'd be likely to see your
post is an hour after getting home, or about 10 hours after your post.

As for the prior post complaint...

Was the older system running Python 2.x? Is the new one running Python
3.x? If so, read the documentation defining what has changed between 2.x
and 3.x.

Hint: strings in 3.x are UNICODE, while strings in 2.x are plain BYTES.

The database adapter may expect different data types.

Also many times when i try to view the error_log by

tail -F /usr/local/apache/logs/error_log &

i get realtime scrolling of other joomla webistes pho errors and i have hard time trackign my own webistes erros.

is ther a work around for that?

 

[Ferrous Cranus]

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.

#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 repr(query)
print type(query)

print repr(escaped_args)
print type(escaped_args)


but i cannot see the error_log because of constant scrolling of error output.

is this how you mean?



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 repr(query)

print type(query)



print repr(escaped_args)

print type(escaped_args)





but i cannot see the error_log because of constant scrolling of error output.

i try: tail -F /usr/local/apache/logs/error_log | grep nikos &'

and see the follwing. if i dont grep at all i cannot stop the eroor output:

Okey, continue trying and trying i came up with this:


try:
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()
except:
with open("err.out", "a") as f:
f.write( repr(query), type(query) )
f.write( repr(escaped_args), type(escaped_args) )


But i cannot test it without looking at the error log which is scrolling like hell and doesn't even quit with a ctrl+c

How will i manage to troubleshoot?
Please confirm the above is correct and is what you were propsoing i shoudl test.

I take it this 'error log" is shared with other users, and you can't
constrain them to cease and desist for a while?

You really have no directory in which you have write permissions? If
so, perhaps you'd better solve that first.

hello Dave,

no this is the general error log apache produces for all the server.

Is there a way to grep error logging info, pertainign only to my specific nikos account or my superhost.gr domain?

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()

of cours ei ahve write permissions. Here:

(e-mail address removed) [~]# ls -ld www/
drwxr-x--- 4 nikos nobody 4096 Jul 13 10:33 www//
(e-mail address removed) [~]# ls -ld www/cgi-bin/
drwxr-xr-x 2 nikos nikos 4096 Aug 28 10:41 www/cgi-bin//


whick make it a mysterya s to why
with open("../err.out", "a") as f:

fails to write the file.
