dynamically generating temporary files through python/cgi
Is there a way to dynamically generate temporary files (such as an html, xml or text file) in Python? I'm not sure if I'm explaining myself clearly as I've no clue how to describe this mechanism. I've seen it on certain websites that will generate a file under certain parameters (through forms) that will dissapear (i.e. delete itself) after a specified amount of time. These files usually have some phony string for their filenames...like it's been md5 hashed or something. Is there a group of library functions that allow this? I imagine that if i manually go and allocate a bunch of timers to monitor files, it would be really expensive in load. Or perhaps is this a client-side mechanism?

No. The easiest way, in my mind would be to store the files in a directory according to the hour they were requested, for example, a file generated between 2 p.m. and 3 p.m. today: http://www.example.com/temp/20050428T14/d41d8cd98f00b204e9800998ecf8427e.html Then you can have a cron job that runs every hour that deletes everything in the temp directory generated 24 hours ago. -- Michael Hoffman -- http://mail.python.org/mailman/listinfo/python-list

So you might want to make subdirectories based on the MD5 digest instead, like this: http://www.example.com/temp/20050428T14/d4/1d/8cd98f00b204e9800998ecf8427e.html -- Michael Hoffman -- http://mail.python.org/mailman/listinfo/python-list

hi there
first of you could use the tempfile
import tempfile
tempfile.mktemp('.thefileendingudlike')
i never really studied the cgi capability of python but for example in
php there is the posibility to serve a request with a mime formated
response such as html, gif, pdf, and so on. so if u want to generate
content dynamically u wouldn't need to store those files but generate
and send em on request without having to destroy them later on..
hope this is helpful
cheers
tc

I think the best way to do that is have a web page that generates the files with random filenames. These files probably ought to reside in their own special directory. This web page gives the user a link to the filename. Next, have a cron job kick off every 5 minutes or so that deletes any files that are older than 'X' minutes. This seems to be the simplest approach. jw -- http://mail.python.org/mailman/listinfo/python-list

Thanks, - poisondart Typically such functionality would be provided by having the server periodically run a task to delete files from the temporary directory whose age exceeds a given value. regards Steve -- Steve Holden+1 703 861 4237 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ Python Web Programming http://pydish.holdenweb.com/ -- http://mail.python.org/mailman/listinfo/python-list
