That's why you got no output - I was mistaken about conferrpath (which is for config errors only). Console output always goes to stdout when the library is compiled with CONSOLEINFO defined (which should be the case).


The second session fails because the SyncML document is wrong. The status for Alert has a <Next> element at the <Data> level of the item instead of inside an <Anchor> element. This is invalid by the SyncML DTD.


Judging from what we've seen so far, that SyncML inplementation in the xperia seems quite sloppy. Of course you could add a workaround in the SyncML TK to accept the <next> tag (and probably <last> as well) outside of <Anchor>, but I doubt that sync will run cleanly afterwards.

:-)


This is a SyncML TK error code and means "Document does not conform to SyncML DTD". If you have console output for the library, you'll see the decoding messages there, along with some context where it happens. That would be useful.

By default, libsynthesis does not output console messages, but you can set the config variable "conferrpath" to "console" to have it on stdout or specify a file path for storing the console messages.


Apparently, the xperia has a number of small WBXML issues, so the most interesting part of the logs at this time would be the console messages with the SyncML TK output. Of course, the .html log might also give some more context.


Makes sense. Quoting only the essential lines here is probably most helpful for the list audience.

That's wrong on SE's part, and is certainly the reason why Wireshark does not recognize it as SyncML, but apparently is not be a problem for the SyncML TK decoder. If it was a problem, it would not decode anything in that message.

It responds according with authentication to WireShark. Try using 
WireShark on capture file and decode port 9321 as HTTP.
wbxml2xml also fails to extract authentication information.

It seems however that public ID "//SYNCML//DTD SyncML 1.2//ENmlq\0031.2" 
instead of "//SYNCML//DTD SyncML 1.2//EN" also causes some problems. For 
example WireShark shows WBXML tag numbers instead of interpretting them 
as SyncML WBXML tags.

Forcing use of SyncML 1.2 for wbxml2xml does not help (wbxml2xml -l 
SYNCML12 ...)

Thanks.

I found a bug which was causing this, and commited a fix in the luz branch (see https://gitorious.org/libsynthesis). The problem was that the XML encoder in the SyncML toolkit could not handle empty tags, but the SonyEricsson devInf contains a <OEM></OEM> empty tag.

So now the XML conversion of the messages you captured from the Xperia-S (aka LT26i) now work ok.

However, this does not explain the auth problems.


I don't see any authentication in the incoming messages, not in the XML translation and also not when looking at hexdumps of the WBXML. The only thing I see is the <LocName> test, but that's not enough for an auth attempt, there must be some credentials.

It is valid (or even recommended) for a device to try first without any credentials to see what auth method the server requests.

So the first of these attempts is perfectly ok, and the server responds with an authentication challenge for MD5 auth, which is the secure method which does

Andris Pavenis — 2012-05-21T13:43:18

Tried to test whether synchronization works with Xperia-S own SyncML 
client (comes with Android 2.3.7 installed on phone, software version 
6.0.A.3.73) using custom libsynthesis based SyncML server.

- the first problem was chunked transport encoding use by phone software 
initially not supported by mentioned above server software. It was 
however easy enough to fix.
- the next problem is failure of libsynthesis to get authentication 
information sent by phone extracted from messages. Also decoded incoming 
WBXML messages saved into XML format are corrupt. For unknown reason the 
client tries to synchronize at first without authentication even when 
both user name and password are specified in its configuration. 
Authentication is first provided in second attempt of 4 totally. 3 of 4 
incoming WBXML format packets seems to contain authentication 
information but also wbxml2xml does not show it

I'm including:
- wireshark capture of communications between client and server (local

The problem is that CTCap is not necessarily tied to a datastore. It is since SyncML 1.2, but wasn't before. That's also the reason why getRelatedDatastore() can be NULL. It is also NULL when using a type from a script with the MAKETEXTWITHPROFILE et. al. functions.


<insert English word for "Jein">. The datatype context indeed exists only once per type, so the script variables exist only once.
However, the init script might be called more than once if multiple datastores are using the same type. The TScriptContext object will be the same, but script functions that use fDsP (see below) can return different information. So using these in the initscript usually makes no sense.


For getting the local datastore related to a particular script invocation, there is

scripts + datastore

Patrick Ohly — 2012-04-25T13:11:07

Hello!

I am trying to solve one issue in SyncEvolution: when trying to find
pairs, it needs to know on a per-datastore basis whether both remote and
local storage have truly unique UID/RECURRENCE-ID that can be relied
upon (iCalendar 2.0 semantic).

So far, I am using a compare script for that, but it has to make
assumptions about the peer. To overcome that I added code that allows
clients to add SyncCap entries to the CTCap (similar to the "can restart
flag"). This information is stored at the receiving end in the
TSyncDataStore base class by the TRemoteDataStore while parsing the
SyncCap (again, very similar to "fCanRestart").

But now my problem is: how can the compare script access that
information?

It runs inside the "datatype context". Does that mean that all
datastores sharing the same type also share the same context and that
the <initscript> for the type is only invoked once?

The script functions in multifielditemtype.cpp (like SYNCOP()) looked
promising. It's possible to get a pointer to some ki

Patrick Ohly — 2012-04-24T08:52:55

It would be pretty hard. The HTTP server in SyncEvolution is written in
Python using the Twisted framework and depends on the D-Bus API provided
by the SyncEvolution core, so one also inherits all the rest of
SyncEvolution (own configuration system, backends, etc.).

For writing one's own server, the Synthesis SDK and server will be
easier.

It depends on how complicated your database schema is. If you can map the fields from the <fieldlist> more or less 1:1 to fields in your database, this is indeed easy to do with libsynthesis. You can do the mapping in the XML config, with no need to code anything in Java.
You'd need to install the ODBC driver for Oracle though, as libsynthesis uses ODBC to connect to databases.


Not based on libsynthesis at this time.

Synthesis still provides a full server as a commercial product, and there are free demo and eval packages of a complete server you can download from their site. The database connection part of these is exactly the same as in opensource libsynthesis, so to check if integration with your Oracle DB works you could use the Synthesis EVAL version.
After that, it'll be a make or buy decision wether you want to license the server from them, or build your own based on libsynthesis. The database connection will be the same.

Glad to hear it works now!


The TEL_FLAGS is just an integer field used as a bitmap to create the TYPE parameter. So bit 0 set will add HOME, bit 1 WORK etc.

So to make a TEL;TYPE=WORK:123456789 telephone number (all three the same in this sample), you would something like:

     // - strings in an array
     sInt32 telFieldID = [aItemKey valueIDByName:"TEL"];
     sInt32 telFlagsID = [aItemKey valueIDByName:"TEL_FLAGS"];
     for (int i=0; i<3; i++) {
       [aItemKey setStringValueByID:telFieldID arrayIndex:i toValue:< at >"123456789"];
       [aItemKey setIntValueByID:telFieldID arrayIndex:i toValue:(1<<1)]; // set bit 1 to make it a WORK number
     }

The other fields, "TEL_LABEL" and "TEL_ID" are to support the custom label feature of the iOS address book, and also to expose the iOS ID of the array elements. If you have your own address book database, you probably don't need these and you could remove these extra fields from the XML config as well.

The sync works now. But some other problems aboutthe set value.

I just try it as what to told me to do, and the client works. Thank you
very much.

For property "TEL" in the vcard, it just has too many enum values, how
could i set the "TEL" value with its enum flags. If only set it by the

myself.

I would really discourage using a mixture of ObjC and parts from the C++ examples. The ObjC wrapper was done exactly because dealing with the fCB and it's members directly is difficult, and you need to do all the memory management on your own.

EXC_BAD_ACCESS is a bus error which is hard to debug, especially as two completely different memory management systems need to cooperate here (ObjC refcounted world with C++/C traditional malloc/free world).

The ObjC wrapper classes however are really simple to use from the ObjC world.

I made a skeleton for the two read* methods to show how to easily access fields from ObjC, without any messing with fCB, and with automatic conversion from NSString (the SettingsKey also gives you convenience methods to access dates as NSDate and integers).

Unfortunately, the sample app did not output the config error messages to the console as it should have. I fixed this, please see the lastest commit in the luz branch on gitorious (the config variable "conferrpath" must be set to "console"). With this, the XCode debug console shows what is the problem:

 Fatal: Module does not understand params passed in <plugin_params>

This is because the sample uses the <datafilepath> <plugin_param>, which is specific to the SDK_textdb plugin, and is not understood by the dummy plugins. So just comment out or remove the entire <plugin_param>, and the sync engine will initialize correctly.

In the same commit, I also added a line to enable syncml engine logs to tmp/sysynclogs for DEBUG builds, so it is easier to get started with the sample and see what the SyncML engine
