sbackup

Plans for Non-Gnome environments?

Asked by Andreas

Hi there,

I'm happily using sbackup on my Ubuntu netbook and thought I give it a go on OS X as well (MacPorts installed, no GNOME environment running though). Installation goes fine if you disable dbus-reload and gconf-schema-install:

make install DISABLE_MAKEFILE_DBUS_RELOAD="yes" GCONF_DISABLE_MAKEFILE_SCHEMA_INSTALL="yes"

But running sbackup-config-gtk then fails:

 $ sbackup-config-gtk
Traceback (most recent call last):
  File "/usr/local/bin/sbackup-config-gtk", line 30, in <module>
    system.set_gio_env_from_session()
  File "/usr/local/share/sbackup/sbackup/util/system.py", line 278, in set_gio_env_from_session
    _set_envvar_from_session(key = 'GNOME_KEYRING_CONTROL')
  File "/usr/local/share/sbackup/sbackup/util/system.py", line 345, in _set_envvar_from_session
    _session = get_session_name()
  File "/usr/local/share/sbackup/sbackup/util/system.py", line 356, in get_session_name
    if grep_pid("gnome-session") is not None:
  File "/usr/local/share/sbackup/sbackup/util/system.py", line 444, in grep_pid
    output = exec_command_stdout(args = ["pgrep", processname])
  File "/usr/local/share/sbackup/sbackup/util/system.py", line 428, in exec_command_stdout
    _output = subprocess.Popen(args, stdout = subprocess.PIPE, env = env).communicate()[0]
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 623, in __init__
    errread, errwrite)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1141, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Do you have any plans to make sbackup run in a non-Gnome environment or could you give me some hints how to achieve that? I don't see why gnome-session or gnome-keyring should be absolutely vital to run sbackup.

Cheers,
Andreas

Hello Andreas,

thanks for using SBackup.

Well, personally I've no intention to port SBackup to non-free OS such as Windows or OS-X. One reason for this is the lack of testing machines running these operation systems. However, nothing speaks against such port and I'm willing to incorporate fixes and patches to support it: improvement of install scripts, workarounds etc.

Your considerations regarding 'GNOME_KEYRING_CONTROL' are correct though I'm not sure about required workarounds.
At first, please file a bug report for this issue. Next step could be a list of environment variable not available on OS-X and some patches to work around these. Do you have some programming experience? Can you run SBackup from tarball or even bzr branch?

So long,
Jean-Peer

Hi Jean-Peer,

thanks for responding to my query.

It turns out pgrep (used in grep_pid()) was missing on my OS X system, which is why seemingly some environment variables couldn't be read. Furthermore I had not installed some more dependencies (dbus-python, py-gnome and proctools; lots of gnome related stuff was already installed, so can't give a full dependency list for Mac ports users).

When launching sbackup-config-gtk with sudo I get the following error message:

"""
Unable to get PID of process 'gnome-session'.

However
$ echo $DBUS_LAUNCHD_SESSION_BUS_SOCKET
/tmp/launch-06QVF7/unix_domain_listener
and
$ ps ax | grep dbus
  213 ?? S 0:00.02 /opt/local/bin/dbus-daemon --nofork --session

Any idea where to look next?

Thanks,
Andreas
