idautils.Functions() makes incorrect assumption #41

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
If MinEA() does not reside in a function then the following (equivalent)
calls will return nothing:

idautils.Functions()
idautils.Functions(idc.MinEA(), idc.MaxEA())

The problem is on line 218:

http://code.google.com/p/idapython/source/browse/trunk/python/idautils.py#218
func = idaapi.get_func(start)

This needs to be encapsulated in a loop to find the start of the first
function:

func = None
while not func:
    func = idaapi.get_func(start)
    start += 1

We're having this issue too with 5.5.  I think you can just call 
idaapi.get_next_func(0) to find the first function?  Maybe?

This should be fixed by http://code.google.com/p/idapython/source/detail?r=199

If it reproduces for you with the trunk version of idautils.py, please send me 
an example IDB.
You can just copy the latest version of the script over the one that comes with 
5.5.

I take the silence as agreement. Case closed for now. ;)

Huh.  I thought I'd have gotten email about your comment #2, but I didn't.  The 
fix in 
r199 works for us.

Gergely,

Weird. I only got notification on this recent message from you. Fix looks good.
