Built deluge from develop on archlinux. Install and start the daemon with
systemctl. Start deluge-console. The local daemon is not shown as
contactable.

The log shows:
14:47:38.112 [WARNING ][deluge.transfer :136 ] Failed to decompress (25
bytes) and load serialized data with rencode: loads() got an unexpected
keyword argument 'decode_utf8'

Running 'python2', importing rencode and calling loads() manually it does
accept the 'decode_utf8' keyword.

If I use inspect in transfer.py to show in the log the function signature
for loads() it says:
ArgSpec(args=['x'], varargs=None, keywords=None, defaults=None)
which does not match the behavior in the interactive session ie no
'decode_utf8' keyword param.

There is a bug against rencode on github which appears to be the same
issue:
https://github.com/aresch/rencode/issues/15

I note that the call to rencode.dumps() in transfer_message() in
transfer.py does not do any utf8 encoding, so I tried just removing the
'decode_utf8=True' arg, but I get:
9:29:29.127 [INFO ][deluge.core.rpcserver :171 ] Deluge Client
connection made from: 127.0.0.1:54980
19:29:29.155 [INFO ][deluge.core.rpcserver :197 ] Deluge client
disconnected: Connection to the other side was lost in a non-clean
fashion: Connection lost.

I may be unable to access the internet in the next week (China!).
Apologies for any delay in responding to updates on this.

Comment (by pjlbyrne):

This problem has now gone away.

I never traced the exact source of the fault, but I did come to realise
that the advice on the archlinux wiki - to use its package manager
'pacman' to manage packages - conflicted with the deluge setup.py script
which appears to use setuptools to install its own packages.

By the time I had purged all the python modules, reinstalled using pacman
and rebuilt, then the error seemed to have gone away.

I recommend that this bug should be closed. A positive result from this
would probably be guidance on the wiki for building on archlinux. Perhaps
I could write that. Or a pacman package to build deluge from the dev
branch.

This is an odd issue and would be interesting to know what version of
rencode was installed. Anyway thanks for updating

Comment (by pjlbyrne):

I'm sorry but I think the state is lost now. I assume the installed C
Library version of rencode conflicted with the python module in some way.

For me the takeaway from this is that there seem to be two different ways
of doing things that clash:

1) A python install script might use pip or setuptools to download the
modules required for the build.

2) Advice on the archlinux wiki states something like "don't use pip to
install extra python modules, you should always use the archlinux package
tool pacman"

I suppose the long-term solution for this would be for python build
scripts to have a way of requesting the package tool for whatever
distribution the linux is built on to do the module install. However, if
such mechanism exists I am not aware of it!

Wiki instructions to build deluge on archlinux are probably a more
realistic short-term win.
