Hi there, I am trying to use python-shout 0.2.1 to broadcast to a icecast 2.4.0 server, which result in a segmentation fault and I can't understand why. Is anyone else experiencing this problem? Here is the config that I use with icecast 2.4.0. <icecast> <limits> <clients>100</clients> <sources>2</sources>

...or either the Closure or the OClosure, there was enough inaccuracy in python reference counting to cause a leak or double-free. We were not consistently checking for python function failures (such as when a wrong type is passed in). While touching this, drop a pointless cast to char* when calling PyArg_ParseTuple, and rearrange some of the code for fewer loops over args/optargs in the generator. Fixes: 4fab2104ab Fixes: bf0eee111f Fixes: 82dac49af0 --- I'm pushing this as followup to my previous patch. I'm pretty embarrassed that we've let nbdsh leak as many bytes as were read via h.pread(),...

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

Fix some things I noticed while reviewing v1, and follow Rich's idea to add a new nbdkit_set_error() utility function with a binding for Python users to request a particular error (rather than being forced to live with whatever stale value is in errno after all the intermediate binding glue code). I could not easily find out how to register a C function callable from perl bindings, and have

Attached is a patch against shout-python-0.2 which does two trivial but very useful things (1) The function "get_connected" is exported so that shout-python becomes usable in nonblocking mode. In the current version of shout-python "open" raises an exception in nonblocking mode. (2) The global interpreter lock is released in the potentially blocking functions
