This patch proposes to drop support for Python 2 in nbdkit. Rather than abruptly drop it everywhere, my proposal is that we point people to nbdkit 1.14 (the current stable version) if they want to continue with Python 2 plugins, while gently reminding them of the upcoming Python 2.7 end of life announcement. Libnbd never supported Python 2. Libguestfs in theory supports Python 2 but I dropped

Much more annoying that it needs to be, but I have tested it and it works on Python 2 & 3. Note this will not work on Python 3.0 - 3.2, but I guess we don't care about those versions. Rich.

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, continuing what started a couple of weeks ago [1], the attached patch series continues the work in making it easier to build and run libguestfs (in fixed appliance mode) on OSes different than Linux. The provided changes should cause no functional changes on Linux. [1] https://www.redhat.com/archives/libguestfs/2014-October/msg00176.html Thanks, -- Pino Pino Toscano (9): build: check

This commit starts to split our massive, monolithic configure.ac file into smaller files, using the m4_include mechanism to combine them. I don't know if we should really do this, so I'm open to comments about it. However: - Our configure.ac script is 1800+ lines long, and that's pretty long. - configure.ac lacks structure; splitting it up might improve that. - From what I read,
