[New-bugs-announce] [issue28610] Provide PDB hook to customize how to find source files

[Pinku Surana]

New submission from Pinku Surana:

I am using Python as a hosted scripting runtime for a product. All the user scripts are stored in a database. I use "compile" and "exec" to run the scripts. I'd like to use PDB to debug scripts. Unfortunately, PDB makes a call to linecache, which calls tokenize.open assuming the code is in a file. I'd like to pass in a function that takes a filename and returns the source code in a string. 

At the very least, moving the call to "linecache.getline" into a separate method in PDB ("self.get_lines") would allow me to override that method with my own.
