evolution2 plugin hangs

[darkeye]

I'm trying to sync between a SyncML-enabled cell phone and evolution 2. It seems all is going well during the sync, but at the very end, the process just hangs. There's no CPU load at that time, so it seem it locks up somewhere. if I replace the evolution plugin with a file plugin, all works fine - so the issue will be probably with evolution.

I'm using libopensync 0.21 on Gentoo Linux.

here's the very end of mysynctool's output:

Sent an entry pas-id-45D809AA000001BE of size 123 to member 1 (evo2-sync). Changetype ADDED
Sent an entry pas-id-45D809AA000001BF of size 103 to member 1 (evo2-sync). Changetype ADDED

and that's it. here's the sync group configuration:

$ msynctool --showgroup "keitai denwa"
Groupname: keitai denwa
Member 1: evo2-sync
        Configuration : <config>

The evolution plugin hangs while syncing with opie-plugin as well.

[Angus]

After more investigation its not the evo2 plugin that hangs its the opie plugin.

[darkeye]

forgive my ignorance, but is the opie plugin part of the evo2 plugin? or part of the syncml-obex-client plugin? (there are the two plugin I've used when encountering this hang)

in any case, is a fix expected any time soon? would there be a workaround even?

[richardcookson]

I have exactly the same problem on Ubuntu, libopensync 0.22. The phone I'm using is a Nokia E61. The plugins I'm aware of using are evo2 and syncml-obex-client.

[darkeye]

it would be so nice if this was fixed - currently this really is a showstopper :(

[pmarat]

could you provide traces?

[darkeye]

what traces are you thinking of? strace output?

[pmarat]

no ... i mean opensync traces like:

export OSYNC_TRACE=/path/to/trace

[darkeye]

excuse me my not knowing, but I don't have a trace program as part of msynctool:

# equery files msynctool | grep bin
/usr/bin
/usr/bin/convcard
/usr/bin/convtest
/usr/bin/msynctool
# equery files app-pda/libopensync | grep bin
/usr/bin
/usr/bin/osyncbinary
/usr/bin/osyncdump
/usr/bin/osyncplugin
/usr/bin/osyncstress
/usr/bin/osynctest

can you be a bit more specific on how to generate the trace you need?

[pmarat]

look here: http://www.opensync.org/wiki/tracing

[darkeye]

hm, I'm using msynctool, and that doesn't seem to honor these environemnt variables.. can I generate traces with msynctool as well somehow?

[darkeye]

strange enough, the manual for msynctool sais that it would take the OSYNC_TRACE environment variable into consideration - but seemingly it doesn't, or the tool hangs before any of the traces would be created:

$ echo $OSYNC_TRACE
/home/maroy/tmp
$ ls $OSYNC_TRACE
$ msynctool --sync "keitai denwa" --conflict 2
...
Member 2 of type syncml-obex-client just sent all changes

Conflict for Mapping 0x2aaaac2ee8e0: Overwriting conflict
All conflicts have been reported

then the thing hangs, as originally described in the bug-report, only CTRL-C helps. afterwards, there are no trace files in the OSYNC_TRACE directory:

$ ls -la $OSYNC_TRACE

[cstender]

It seems that you have built opensync without tracing support. I looked at ​http://sources.gentoo.org/viewcvs.py/gentoo-x86/app-pda/libopensync/libopensync-0.21.ebuild?rev=1.1&view=markup and found "$(use_enable debug tracing) \" so I think you have to activate tracing.

[Peper]

You need to enable debug useflag.

[darkeye]

tarball of trace logs

[darkeye]

thanks for the tip - I re-emerged with the debug flag, and now it produces trace output. I tried to attach it to this ticket, but even a bzip'd tarball is too large. anyway, you can download the tarball of the logs from here: ​http://tyrell.hu/~darkeye/synclogs.tar.bz2

just having a quick check for errors, I got a _lot_ of these, from my group 1 thread (which is the evolution plugin thread):

[1174737723.274688]             <--- ERROR --- osync_db_remove_changelog: Unable to remove log! no such column: objtype

and later on, there's this:

[pmarat]

it seams that you have used a pre 0.21 sync group with 0.21> opensync.

In 0.21 there was an incompatible DB change that adds objtype (NOT-UNIQUE-UID fix)

please cleanup your syncgroup http://www.opensync.org/wiki/FAQ#HowdoIcleanupasyncgroupfortesting or create a new syncgroup and test again

[darkeye]

started with rm -rf ~/.opensync , re-created the groups, and I sort of get the same, without some of the error messages.

the output of msynctool is:

...

then it stops (no CPU load anymore, but does not return)

I get the following error in one of the log files:

[1174741332.182745]                         <<<<<<<  get_next_vertice_neighbour: None found

[darkeye]

oh, does this mean this bug won't be fixed anytime soon? :(

[pmarat]

at least not for 0.22 ;-(

could you please prove new traces ... the old one points to the missing database cleanup

[darkeye]

sure, I updated it...

if there's any other way for me to provide information, please let me know..

[darkeye]

oops, I inadvertantly deleted milestone 0.23

[dgollub]

Milestone 0.23 deleted

[bornmw]

Would like to report exactly the same issue. It happens both with sunbird and evo2 plugins 0.22. They come with Fedora 8. My phone is Nokia N70. I tried to compile 0.34, but after a couple of cmake errors I gave up. Please, make the software you produce usable.

[bornmw]

I've just found a workaround here: ​http://geektalk.andreat.de/2006/11/how-to-syncronize-nokia-n70-palm.html

Evolution sync works when started like this: msynctool --sync evo2 --filter-objtype note --filter-objtype todo

But it doesn't help the sunbird.

[bornmw]

Actually evo works with msynctool --sync evo2 --filter-objtype note

[smoku]

This is definetely related to Notes synchronisation. If I configure the note_db in syncml-obex-client the synchronization hangs. If not configured or --filter-objtype note option for msynctool used, it finishes OK.

The notes are fetched ok (on the phone display), but:

Conflict for Mapping 0x8104330: Newest entry used
Conflict not resolved: No revision function set
Conflict for Mapping 0x8145f08: Newest entry used
Conflict not resolved: No revision function set

Conflict for Mapping 0x822c1b0: Newest entry used
Conflict not resolved: No revision function set
All conflicts have been reported

suggests that one of the participating plugins have problems with conflict resolution "No revision function set". I guess it's the evo2-sync plugin:

smoku@wing:~$ msynctool --showgroup nokia
Groupname: nokia
Member 1: evo2-sync
	Configuration : <config>
<address_path>default</address_path>
<calendar_path>default</calendar_path>
<tasks_path>default</tasks_path>
</config>

Member 2: syncml-obex-client
[...]

The evo2-sync has only address, calendar and tasks paths configurable. There is no notes_path, so I guess Notes synchronization is just unimplemented in Evolution2 plugin.

[smoku]

BTW, I have:

smoku@wing:~$ msynctool --version
This is msynctool version "0.22"
using OpenSync version "0.22"
