Hi, When an integer argument is passed as value, node_set_value segfaults. Reproducer is at the end of this message The backtrace points at hivex-py.c, function get_value. While obj is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL. Kind regards, Peter https://lekensteyn.nl #!/usr/bin/env python3 import hivex, sys h = hivex.Hivex(sys.argv[1]) print(h) val = {

Hi, This patch series is based on a prior patch[1], splitting off changes as requested and incorporating feedback from Richard Jones. It introduces type validation to avoid segmentation faults (instead, it reports an exception) and fixes handling of the bytes type in Python 3. Major changes since that series: - Drop newly introduced support for integer types for DWORD/QWORDS - Reject Unicode

Hi, I have been working on a Python application that uses hivex. Meanwhile I have encountered some Python bindings issues which could be fixed. The next issue I see now is about the value_value function. This is briefly documented as: "return data length, data type and data of a value". For Perl, Python and OCaml, this is not true. A tuple is returned for both without the length

Kind regards, Peter https://lekensteyn.nl [0]: https://www.redhat.com/archives/libguestfs/2014-August/msg000...
