Thanks Steven , i made some alternations to the variables names and at
the end of the way that i check a database filename against and hdd
filename. Here is the code:
#
=================================================================================================================
# Convert wrongly encoded filenames to utf-8
#
=================================================================================================================
path = b'/home/nikos/public_html/data/apps/'
filenames = os.listdir( path )
utf8_filenames = []
for filename in filenames:
# Compute 'path/to/filename'
filename_bytes = path + filename
encoding = guess_encoding( filename_bytes )
if encoding == 'utf-8':
# File name is valid UTF-8, so we can skip to the next file.
utf8_filenames.append( filename_bytes )
continue
elif encoding is None:
# No idea what the encoding is. Hit it with a hammer until it stops
moving.
filename = filename_bytes.decode( 'utf-8', 'xmlcharrefreplace' )
else:
filename = filename_bytes.decode( encoding )
# Rename the file to something which ought to be UTF-8 clean.
newname_bytes = filename.encode('utf-8')
os.rename( filename_bytes, newname_bytes )
utf8_filenames.append( newname_bytes )
# Once we get here, the file ought to be UTF-8 clean and the Unicode
name ought to exist:
assert os.path.exists( newname_bytes.decode('utf-8') )
# Switch filenames from utf8 bytestrings => unicode strings
filenames = []
for utf8_filename in utf8_filenames:
filenames.append( utf8_filename.decode('utf-8') )
# Check the presence of a database file against the dir files and delete
record if it doesn't exist
cur.execute('''SELECT url FROM files''')
data = cur.fetchall()
for url in data:
if url not in filenames:
# Delete spurious
cur.execute('''DELETE FROM files WHERE url = %s''', url )
=========================
Now 'http://superhost.gr/?page=files.py' is not erring out at all but
also it doesn't display the big filename table for users to download.
Here is how i try to print the filenames with button for the users:
=================================================================================================================
#Display ALL files, each with its own download button#
=================================================================================================================
print('''<body background='/data/images/star.jpg'>
<center><img src='/data/images/download.gif'><br><br>
<table border=5 cellpadding=5 bgcolor=green>
''')
try:
cur.execute( '''SELECT * FROM files ORDER BY lastvisit DESC''' )
data = cur.fetchall()
for row in data:
(filename, hits, host, lastvisit) = row
lastvisit = lastvisit.strftime('%A %e %b, %H:%M')
print('''
<form method="get" action="/cgi-bin/files.py">
<tr>
<td> <center> <input type="submit" name="filename"
value="%s"> </td>
<td> <center> <font color=yellow size=5> %s
</td>
<td> <center> <font color=orange size=4> %s
</td>
<td> <center> <font color=silver size=4> %s
</td>
</tr>
</form>
''' % (filename, hits, host, lastvisit) )
print( '''</table><br><br>''' )
except pymysql.ProgrammingError as e:
print( repr(e) )
