GetOpType and GetOperandValue are destructive #25

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The functions GetOpType and GetOperandValue affect the DB. This is
unexpected of 'Get' functions.

The problem is that these functions call ua_code, which creates an
instruction. This is obviously a problem if the desired address is not a
code at all, but can also cause undesired result when the address already
contains an instruction.

The problem can be easily fixed by using ua_ana0 instead. It sets the 'cmd'
variable, thus allowing 'get_current_instruction' to work properly, but
without changing anything in the DB.

What version of the product are you using? On what operating system?
IDAPython 1.0.0

The problem should fixed. Both functions now use decode_insn() which should not 
be destructive.

Thanks for the report!
