Diff gets stuck at 58%

[karpiyon]

Hi,
I am diffing 2 files.
At first I exported the sqlite including small functions and run teh diff.
The sqlite was ~2.4Gb and it always got stuck at around 57%.
I decided to try to generate sqlite without small functions and not to select "Use the decompile" and this time the sqlite files were reduced to ~500MB yet the process gets stuck at ~58%.

I let it run for 3-4 hours and it is still stuck.

What can i do to assist in debugging this or to complete the process?

I can try and upload the sqlite if it helps

It's most likely finding compilation units, found so many, and is still matching compilation units. I recommend you to wait as it might take more than 4 hours if that's the case. If you want to see if that's the case run a query like this one for each exported SQLite database:

select count(*) from compilation_units;

If it returns hundreds or thousands of them, well, that's the culprit of why it's taking long.

If you prefer to disable this heuristic, you will need to write a diffing script to disable the Related compilation unit heuristic. Basically, in the on_launch_heuristic event do return False for that heuristic. You have a skeleton example for such script here: https://github.com/joxeankoret/diaphora/blob/master/doc/examples/hooks/hooks_example2.py
