dbus timeout with 0.14

[Iain Buchanan]

Hi all,

I'm sure I've successfully synced with 0.14, although I've been doing so
much syncing and testing packages lately that I'm not certain...

I'm getting a dbus timeout (I think) with synce-opensync-plugin.py.
Basically the partnership creation works, pls works, synce-gvfs works,
msynctool creates the group fine, and I don't have a firewall!

I removed all my partnerships and msynctool groups, deleted .synce
and .opensync, and started again, and I still get the error.

When I sync with:
$ msynctool --sync synce-sync >Desktop/msync-output 2>Desktop/msync-output2

I get this at the end of the STDOUT:
(lots of Received an entry...)
Member 1 of type evo2-sync just sent all changes
Member 2 of type synce-opensync-plugin had an error while getting changes: Error during get_changeinfo() method
Member 2 of type synce-opensync-plugin just disconnected
Member 1 of type evo2-sync just disconnected
All clients have disconnected
The sync failed: Unable to read from one of the members
Error while synchronizing: Unable to read from one of the members

and STDERR says:
Traceback (most recent call last):
  File "/usr/lib/opensync/python-plugins/synce-opensync-plugin.py", line 159, in get_changeinfo
    changesets = self.engine.GetRemoteChanges(self.engine.GetSynchronizedItemTypes())
  File "/usr/lib/python2.6/site-packages/dbus/proxies.py", line 140, in __call__
    **keywords)
  File "/usr/lib/python2.6/site-packages/dbus/connection.py", line 622, in call_blocking
    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.


I have the default file from
synce-hal:  /etc/dbus-1/system.d/org.freedesktop.Hal.Device.Synce.conf

I don't know if it helps, but dbus-monitor shows some errors:

method call sender=:1.177 -> dest=org.freedesktop.DBus serial=9 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=AddMatch
   string "type='signal',sender=':1.175',path='/org/synce/SyncEngine',interface='org.synce.SyncEngine',member='PrefillComplete'"
method call sender=:1.177 -> dest=:1.175 serial=10 path=/org/synce/SyncEngine; interface=org.synce.SyncEngine; member=Synchronize
error sender=:1.175 -> dest=:1.177 error_name=org.synce.SyncEngine.Error.Disconnected reply_serial=10

but I'm not sure what this means!

There's a mass of dbus synce posts on the web, but I can't find any that
match or solve this issue!

Many thanks,

Whatever you do will be insignificant, but it is very important that you do it.

That one only affects connection, won't have any influence here.

Cant tell exactly, but that looks like sync-engine is trying to send a
status signal first, and then sends an disconnected error.

What does the output from sync-engine say ?

Heaps.  Megabytes in fact (15Mb and counting...)

After each "chunk" of hundreds of lines (about 300kb), it ends with:

Finished emitting response 200 code to client

Then prints more hundreds of lines, and ends with the same string.

Can you give me a grep or something to run over it?  I had a look
through and it doesn't look interesting...

thanks :)

Specifically, no, but i'd expect to see an exception somewhere I
suppose...
