python wrapper is broken

[cstender]

While building libopensync from svn I get the following warnings:

cd /usr/src/packages/BUILD/libopensync-0.36_SVN3433/build/wrapper && /usr/bin/gcc   -D_opensync_EXPORTS -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -O2  -fPIC -I/usr/src/packages/BUILD/libopensync-0.36_SVN3433/build -I/usr/src/packages/BUILD/libopensync-0.36_SVN3433/opensync -I/usr/src/packages/BUILD/libopensync-0.36_SVN3433 -I/usr/include/python2.5   -fno-strict-aliasing -o CMakeFiles/_opensync.dir/opensyncPYTHON_wrap.o   -c /usr/src/packages/BUILD/libopensync-0.36_SVN3433/build/wrapper/opensyncPYTHON_wrap.c

This leads to the following traceback:

Traceback (most recent call last):

    File "/usr/lib/python2.5/site-packages/opensync.py", line 10, in <module>

        import _opensync

ImportError?: /usr/lib/python2.5/site-packages/_opensync.so: undefined symbol: osync_objtype_sink_num_objformats

looking more at it, it seems the function got renamed with changeset:3319.

int osync_objtype_sink_num_objformats(OSyncObjTypeSink *sink) 

was renamed to

unsigned int osync_objtype_sink_num_objformat_sinks(OSyncObjTypeSink *sink)

Puuh, i had a brief look on this - my python knowledge is quite rare... I failed on how to handle lists in python - this seems to be the hardest part in the swig stuff. Reschedule the ticket to 0.39 - since 0.39 should contain the latest API changes.

Replying to felixmoeller:

looking more at it, it seems the function got renamed with changeset:3319. {{{ int osync_objtype_sink_num_objformats(OSyncObjTypeSink *sink) }}} was renamed to {{{ unsigned int osync_objtype_sink_num_objformat_sinks(OSyncObjTypeSink *sink) }}}

Thanks for the hint... renamed.

But there are still some issues left:

Getting this in debian too.

Three functions renamed form osync_objtype_sink*objformat to osync_objtype_sink*objformat_sink
