Description Simon Feltman 2014-05-04 22:32:05 UTC 
Methods which take GBytes as arguments should allow automatic conversion from Python bytes objects (or really anything that implements the Python buffer protocol).

Currently a GBytes object needs manual construction. I assume this is also the case for GByteArray.

>>> from gi.repository import GLib, Gio
>>> inbytes = GLib.Bytes.new_take(b'asdf')
>>> stream = Gio.MemoryInputStream.new_from_bytes(inbytes)
Comment 1 John Stowers 2014-05-08 12:03:08 UTC 
I've kind of got a need for this (specifically, taking data from objects implementing the buffer protocol).

In that case I assume the integration must be done in C.

Do you have any pointers or examples in the current codebase of integrating code in this way so I make start to hack on this?

Here's a brain dump, tutorial style:

Me too.  I need that for proper binding of hb_blob_create.  See bug 742494.  Thanks.

Any chance someone can take a look into this?  Thanks :).
