'module' object has no attribute 'session_settings'

[NetSharkDon]

Hi arvidn
I use libtorrent python binding ,version '1.2.0.0'
when i run python client.py
ERROR
“AttributeError: 'module' object has no attribute 'session_settings'”
HELP ME PLEASE! thanks

I could confirm that this is currenlty broken.

You could try test.py to check that your compilation does work.

I will fix it.

Thank You Very Much
libtorrent 1.1.1 can work
hope for 1.2

This problem is still alive with the Deluge torrent daemon.

[arvidn]

session_settings were deprecated a long time ago in favour of settings_pack. I seem to recall it’s still there though, as long as you build with deprecated functions enabled (which is the default)

[arvidn]

Do you have any more details on version of libtorrent and how it was built?

I'm getting this on upgrade to libtorrent-rasterbar-1.2.0. Deluge fails due to the missing session_settings. It's definitely not there:

Python 2.7.15 (default, Jan 15 2019, 23:07:09) 
[GCC 8.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libtorrent
>>> libtorrent.session_settings
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'session_settings'

On another machine still on 1.1.11:

Python 2.7.15 (default, Jan  2 2019, 21:38:32) 
[GCC 8.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libtorrent
>>> libtorrent.session_settings
<class 'libtorrent.session_settings'>

This is on Gentoo Linux using the Portage ebuilds.

The build does enable deprecated functions:

session_settings has been deprecated for all of libtorrent-1.1.x, it was removed in libtorrent-1.2.

use settings_pack instead.

I think the python bindings actually just use a dictionary instead of settings_pack.

See: https://libtorrent.org/python_binding.html

[dylangerdaly]

Could you have just left it in there?

It's not possible to compile Deluge with the latest version of libtorrent.

[arvidn]

Was settings_pack ever a thing in the python binding? I think it was always just a dict in python.

session_settings have been deprecated since 1.0 iirc

@dylangerdaly @perfect7gentleman Deluge 1.3 is definitely not compatible with libtorrent 1.2, I said that 1.0 was the last proper supported libtorrent. Deluge 2.0 will support libtorrent >1.1 and is to be released soon...
