pydia

The ultimate Python wrapper for the Microsoft's DIA SDK (Debug Interface Access)

Goal

pydia aims to ease the manual handling of PDB files. No more hacking together some IDA-Python - you can now use your favorite python ditribution and simply install a package! pydia makes all the common functionality used when working with PDB files extremely accessible.

My future vision

Hopefully, we can make pydia so powerful we will be able to accurately recreate header files from PDBs alone.

How?

The ideaology of pydia is as follows:

  • Every DIA2 SDK COM function is wrapped by a neat C++ function which handles all memory allocation/de-allocation and reference count tracking. These C++ wrappers are found in DiaLib.
  • Each DIA2 SDK "class" is implemented as a C-API Python class in pydia (the sub-project).
    • The C-Python wrapper will never directly call a COM function - rather it will call a DiaLib method which will wrap the low level memory managment.
  • The C-Python wrappings (pydia) must be as user-friendly and safe as possible. It should be actively difficult to missuse pydia's exported Python API.
  • The DiaLib wrappings should be 100% responsible for all low-level management - especially memory-wise. Unless the user is a dehydrated donkey they should not be able to cause DiaLib to "seg-fault" (0xC0000005 - STATUS_ACCESS_VIOLATION).
