[codehelp< at >debian.org: Status of opensync in Debian - mass removal very likely]

Harald Jenny — 2012-03-05T08:11:58

Dear opensync folks,

I guess this may be of interest for you - if you are interested in
keeping opensync in Debian I would ask you to get in contact with the
maintainers (http://packages.qa.debian.org/o/opensync.html).

Kind regards
Harald Jenny

syncML devel equipment

Chris Frey — 2012-02-23T22:41:53

Hi,

What phone or device is recommended to do syncML development?
All I have are blackberries, and I don't think they support it.

Q: osync strings glib vs libstd

deloptes — 2011-12-08T11:28:38

Hi,
I have a theoretical question rather general as I have been doing a lot of
programming for text processing purposes and always had troubles with
encodings, so I was wondering what should one use when coding for opensync.
There are several advantages when using glib, but also several disadvantages
compared to libstd.

Can you please advise? Or where can I post this question if this is not the
right place for that discussion?

regards

EBook / ECal new API

Nicolas — 2011-11-20T14:54:48

Hi,

In helping friends with the last Fedora release, I have noticed that the
ebook / ecal API was modified.

http://www.opensubscriber.com/message/evolution-hackers< at >gnome.org/15214566.html

http://developer.gnome.org/libebook/stable/EBook.html#e-book-free-change-list

We have to worked to adapt opensync evolution2 plugin for the new
Evolution API... Maybe opensync evolution3 plugin :)

May I modify libwbxml-0.11.0 source code to make it compile, and use it in commercial software

Zeng,Weiming — 2011-11-14T07:27:31

Hi,

My question is related to LGPL licensing of libwbxml-0.11.0.

I got the source of libwbxml-0.11.0 but found it won't compile on Windows
using Visual C++ 6 (missing wbxml_config.h). I'd like to modify the source
and make it compile, then use it in the commercial software in a
dynamic-link manner(DLL).  This proprietary is an email client with
ActiveSync capability.

My concern is that as it's bounded by LGPL, may I keep the commercial
software code proprietary, while using a modified libwbxml-0.11.0 ?

My modification is just to make it compile, but not to modify the internal
of libwbxml.

Is this a case prohibited by LGPL, a close source commercial software dynamic
links to a modified version of LGPL software?

Thanks!

*Weiming*

Discussion: syncml plugin with synthesis

deloptes — 2011-10-23T10:40:35

Hi, guys, I'm thinking about writing a plugin that uses the synthesis
engine.
I read about synthesis last year, but I was busy with too many business
stuff to work on something like this.

My proposal is to discuss it here and I'm asking for input basically to work
out the design.
opensync side, so I need some ideas how synthesis can be brought into the
game.

I was thinking perhaps to take over the syncml library, but it looks like
there is too much SyncML stuff to care about, which is already done in
synthesis.

If one of you is interested to assist, please let me know.

Your opinion and estimates are really appreciated.

regards

file renames to resolve version conflicts

Chris Frey — 2011-10-20T04:09:58

Hi,

The following commits have been added to the opensync git repo, to resolve
naming conflicts between opensync 0.2x packages and 0.4x packages:


commit 0a1eb5c84b641a02fa75f507844172f9a5d891d9
Author: Chris Frey <cdfrey< at >foursquare.net>
Date:   Thu Oct 20 00:03:33 2011 -0400

    Renamed python module to opensync1, so it can coexist with 0.2x

commit 1f9e2f3852ee206a2fea506d248a0f006bba4659
Author: Chris Frey <cdfrey< at >foursquare.net>
Date:   Wed Oct 19 23:50:45 2011 -0400

    Renamed some internal variables in osync1plugin to match new program name

commit 46825b649f531899b8623aa4050f84692e8da839
Author: Chris Frey <cdfrey< at >foursquare.net>
Date:   Wed Oct 19 23:49:21 2011 -0400

    Renamed tools from osync* to osync1*, so they can coexist with 0.2x



I think this is a good move for python, since the API changed anyway.
And for the tools/ renames, these are mostly debug and development tools
anyway, so I don't see much impact.

Let me know if you think differently.

Thanks,
- Chris

fixed: evolution syncing problem with get_changeson Debian Squeeze

Chris Frey — 2011-09-23T05:12:16

Hi,

Thought I should post this here as well.  The evolution-data-server
distributed with Debian Squeeze (stable) has a bug in the addressbook
get_changes call, and therefore does not return any changes even if
some were made in evolution.

The patch is available here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=641898

I hope that the next point release of Squeeze will have this fixed, as
well as in Ubuntu.

make test doubts

Luiz Angelo Daros de Luca — 2011-09-02T15:52:55

Hello,

I'm trying to run some of the opensync test (make test) but with no luck
inside the binary-meta.
Is the "make test" supposed to be executed after or before a make install?

If before, make test just fails for every test because it misses some
libraries like inside rootdir/lib and other that are
only inside builddir, like libopensync-testing.so.

If it is supposed to run after the "make install", why this exists in
file-sync test?

ADD_TEST( check_data ${CMAKE_CURRENT_SOURCE_DIR}/check_data
${CMAKE_BINARY_DIR} )

It uses the CMAKE_BINARY_DIR, which is the build dir. Inside the test, this
argument is used for pluginpath suffixed with src:

PLUGINPATH="$1/src"

Clearly, this expects to run before install.


Maybe a "test" target inside the binary-meta makefile would be interesting.
However, it would need to set some env vars as
LD_LIBRARY_PATH and PATH to the respective ones inside source/rootdir.

Another solution would be to set this env inside the test specs, like:

ADD_TEST( check_data ${CMAKE_CURRE

Binary meta fails at "make fetch"

Luiz Angelo Daros de Luca — 2011-08-26T15:02:46

Hello Chris,

I just got a cellphone (and now I can play again with opensync). It is
a simple samsung C3200 that does not work
with any tool under linux. :-)

I saw that binary-meta now has more interesting make options. I tried
"make fetch" from a clean git
and got this error:

libopensync with AMQP

harish badrinath — 2011-07-28T13:00:02

Hello,

I have a question and i don’t know if it makes sense. Please do
correct me, if i am wrong.

Can you use libopensync along with zeromq/rabbitmq (rabbitmq is a AMQP
protocol implementation with zeromq being AFAIK loosely based on AMQP)
to syncornize data with another server that uses liopensync to
synchronize random data ??

Or is it better to use libsyncml to sync arbitary binary data some
media like ethernet.


Thanks,
Harish

Breakthrough: all opensync library tests pass

Chris Frey — 2011-07-23T06:15:24

Hi folks,

I did a test run on opensync tonight, using my git repo, and for the
first time to my memory, in all my experience with opensync, all
the tests pass for me.

Please let me know if you have different results.

It's been a long week of valgrind work, and repairing and debugging tests,
but I'm pretty happy that I'm at this point already.

This is not to say that all the tests are themselves accurate.  I haven't
gone through them and analyzed the logic.  I just wanted the existing
code to run and pass.

Hopefully from now on, we can keep opensync in this good shape.  And
improve it.  There are more corner cases, I'm sure, that valgrind can
catch.

The repo is here, with 65 commits over the past week and a half:

http://repo.or.cz/w/opensync/opensync-cdf.git


So far, all my tests have been with file-sync and mock-sync.  Next on
the agenda is to slowly work through the binary-meta tree, and test
those plugins with valgrind as well.  Hopefully opensync will become
bulletproof soon. :-)

Enjoy,
- Chris

trying to understand the duplicate callback

Chris Frey — 2011-07-22T22:46:03

Hi Daniel,

While fixing leaks, I ran across the following function in the xmlformat
plugin:

http://repo.or.cz/w/opensync/xmlformat-cdf.git/commitdiff/d6bf4461281d96bfeb4bc593a087c04c6e232d3f

I've removed all the dead code (which contained a leak), but while it looks
correct, and the sync continues to work without that dead code, it looks
kinda odd.

I just wanted to confirm:  is is true that the duplicate callback is only
for duplicating the UID?  Why is there an output/outsize mechanism involved
in that case?

How else can the duplicate callback be used?

Thanks!
- Chris

API behaviour change: osync_xmlformat_assemble(and heads-up to ldap plugin author)

Chris Frey — 2011-07-22T22:40:37

Hi,

I've made a memory allocation change to the function
osync_xmlformat_assemble() which can be viewed here:

http://repo.or.cz/w/opensync/opensync-cdf.git/commitdiff/b80405e0eafb0cebf1c034d9f08ceff778bf4fe3

Much of the code that I've seen, both inside the library and in the
plugins, assumes that the resulting buffer from a call to
osync_xmlformat_assemble() can be freed with osync_free() or g_free().

But the call passes back memory that expects to be freed with libxml2's
xmlFree().

If you're on a system that uses malloc everywhere, this might not matter,
but glib/gtk uses its own g_slice memory management, and this might
cause problems.

With the above commit, osync_xmlformat_assemble() gives back an osync_strdup()
buffer, so freeing works as expected.


scriptor:
I've noticed in your ldap plugin code, you free this memory with
calls to xmlFree(), which is very correct, but plugins shouldn't
have to know this.  This change will affect you.

Also, I notice that you make much use of valgrind in your

API change: capabilities API reworked

Chris Frey — 2011-07-18T21:34:45

Hi,

I've made a number of changes and fixed some memory leaks in the capabilities
API.  You can see the last change here:

http://repo.or.cz/w/opensync/opensync-cdf.git/commitdiff/a826a3ce69bd1e84beca7344c18e2a0047306960

I've updated the evolution2, vformat, and xmlformat plugins as well, with
the small API change required, since I'm tracking them.

For plugin authors, the change is pretty simple:

Change: osync_capability_new()

To: osync_capabilities_add_new_capability()

and

Change: osync_capabilities_objtype_new()

To: osync_capabilieis_add_new_objtype()

The reason for this change was because the capabilities API behaved
differently than the rest of opensync.  The _new() calls would add
the new object to an internal list, and return an unref'd pointer.
This is inconsistent with what the user will expect from every other
_new() call in the library.

Also, due to this oddity, some of the internal implementations were
very difficult to get right.  While building the capabiities hierarchy,
there coul

[BUG]s file-sync misses dir references and adouble random number

Luiz Angelo Daros de Luca — 2011-07-18T00:06:15

Hello,

I don't know it the bug tracker at the site is still valid so I'm writing
about the bug I found to the list.
Correct me if I'm wrong.

File-sync/src/file-sync.c at osync_filesync_initialize:

"OSyncFileEnv *env" is initialized with no problem. It contains only a list
of "GList *directories". However, this list is never filled.
At the end of each sink loop, it should add dir to env->directories. The
result is that free_env never frees dirs as
it has no reference for them.


File-sync/src/file.c at conv_plain_to_file:

file->path = osync_rand_str(g_random_int_range(1, 100), error);

the g_random_int_range(1, 100) returns a random number between 1 and 100.
However, the osync_rand_str already does this. Its first argument is "int
maxlength", which is used in:

length = g_random_int_range(1, maxlength + 1);

Seems to be a double random :-). It should be enough to call:

file->path = osync_rand_str(100, error);

FormatEnv setup and teardown logic

Chris Frey — 2011-07-16T01:41:20

Hi Daniel,

I've been working on opensync memory leaks, and found an interesting one
in the FormatEnv unref code:

http://repo.or.cz/w/opensync/opensync-cdf.git/commitdiff/9fcebe4abc933e256fa65bfbb2c1f4936c3966ff

For caps_converters, it looks like it is possible to have init/final logic
in the format plugins, since these functions exist:

osync_caps_converter_set_initialize_func()
osync_caps_converter_set_finalize_func()
osync_caps_converter_initialize()
osync_caps_converter_finalize()

The FormatEnv code does not seem to make use of any of these calls,
so my memory leak patch above does not call finalize().

The merger code on the other hand, only has the following functions
in opensync_merger.c:

osync_merger_set_initialize_func()
osync_merger_set_finalize_func()

There are no functions available to call these callbacks.

Could you give me a bird's eye overview of how the caps_converters and
mergers are supposed to work from an API point of view?  Should I be
implementing init/final sequences in For

[PATCH] Small memoryleak fixed in serializer.c

Luiz Angelo Daros de Luca — 2011-07-15T05:15:21

Hello,

While playing with valgrind, I found some small memory leaks.
I fixed what it found in serializer.c and another one that it did not
found. My code is in:

git://github.com/luizluca/opensync-luizluca.git   fix-memoryleak-serializer

The first do some formatting cleanup (kdeveloper help) and the other
ones are the real fixes.

BTW, there is more memory leaks in code. I just didn't stopped to fix them.
