[nbdkit PATCH 2/2] python: Simplify calling into plugin
PyObject_CallObject is powerful, but awkward - we have to wrap all arguments into a temporary tuple before using it. Let python do more of the work by using PyObject_CallFunction anywhere that all arguments can be described by a Py_BuildValue() format string, instead of creating one-shot arguments ourselve...

[PATCH 0/2] python: improved UTF8 decoding error handling
The Python 3 bindings currently are unable to deal with non UTF8 characters. This series continues what proposed in RHBZ#1406906. A new function 'set_decode_error_handler' allows the User to specify how to deal with decoding errors. The default behaviour will be raising a UnicodeDecodeError. If the handler is changed to 'surrogateescape', non UTF8 characters will be escaped in a

[nbdkit PATCH v2 0/5] FUA support in Python scripts
First out of our four language bindings to add FUA support (for reference, I added 'zero' support for python, perl, and ruby back in 1.1.13, then Rich had to add it for ocaml in 1.1.20). I tested this heavily under python 2, but for now only compile tested under python 3; I plan to do further testing there and make any tweaks if necessary. I wrote patch 5 early on, but then realized I

[nbdkit PATCH 0/5] Counterproposal for python v2 interfaces
As mentioned in my reviews, I wonder if we should make our python callbacks look a bit more Pythonic by having kwargs added for each new flag that we want to expose. The idea was first floated here: https://www.redhat.com/archives/libguestfs/2018-April/msg00108.html Note that with my proposal, there is no need for a python script to expose a global API_VERSION variable; new flags are added
