Questions tagged [cgi]

1) The Common Gateway Interface is a standard defining how web server software can delegate web page generation to a stand-alone application or executable file. 2) Computer Generated Imagery

This tag is mostly used for the Common Gateway Interface (CGI), which is a standard (see RFC 3875: CGI Version 1.1) that defines how web server software can delegate the generation of web pages to a stand-alone application, an executable file. Such applications are known as CGI scripts; they can be written in any programming language, although scripting languages are often used.

Less commonly on Stack Overflow, CGI may also be used to tag questions regarding Computer Generated Imagery.

Will everything in the standard library treat strings as unicode in Python 3.0?

I'm a little confused about how the standard library will behave now that Python (from 3.0) is unicode-based. Will modules such as CGI and urllib use unicode strings or will they use the new 'bytes' type and just provide encoded data?

Letting users upload Python scripts for execution

I understand that letting any anonymous user upload any sort of file in general can be dangerous, especially if it's code. However, I have an idea to let users upload custom AI scripts to my website. I would provide the template so that the user…

So I've been playing around with raw WSGI, cgi.FieldStorage and file uploads. And I just can't understand how it deals with file uploads. At first it seemed that it just stores the whole file in memory. And I thought hm, that should be easy to test…
