Hi,
to increase my speed I have a fast downloadfunction for my images:
def fast_download():
session.forget(response)
cache.action(time_expire=604800)(lambda: 0)()
# very basic security (only allow fast_download on
your_table.upload_field):
if not request.args(0).startswith("Images."):
return download()
#---------check which picture we are allowed to display--------
#----get the db entry and determine whether it is a small or big pic----
rows=db(db.Images.thumb == request.args(0)).select()
try:
rows[0]
except:
small=0
rows=db(db.Images.Image == request.args(0)).select()
else:
small=1
#print rows[0],small
row=rows[0]
if ...#some stuff to determine which image is shown (not relevant)
from PIL import Image
img=row.thumb
filename = os.path.join(request.folder,'uploads',img)
return response.stream(open(filename,'rb'))
which works quite good.
My Problem is that the google image bot tries quite frequently to access
the function directly. which gives an out of range error. (268 in the last
3 weeks)
part of one error ticket:
File "/home/www-data/web2py/applications/Movie_Alarm/controllers/default.py"
<https://www.movie-alarm.de/admin/edit/Movie_Alarm/controllers/default.py>,
line 327, in fast_download
row=rows[0]
HTTP_FROM:
googlebot(at)googlebot.com
HTTP_USER_AGENT:
Googlebot-Image/1.0
REQUEST_URI:
/fast_download/Images.thumb.a791255ac1014c88.7466d626e61696c2e6a7067.jpg
I tried to put fast_download in the disallowed part of the robots.txt
but it seems to have no effect.
and I hate having so many errors in my error database :)
have you guys any ideas how I can prevent this from happening again?
