14 Porting opensync plugin to opensync 0.40
15 ----------------------------------------
16 There's two options to this item:
21 The difference between opensync 0.22 and 0.40 involves some API changes.
22 You should be able to note the changes in the example plugin code once
25 The simple way involves merely updating Barry's opensync plugin to match
26 the new API. This shouldn't be too difficult, but you may run across
29 The proper way involves:
31 - switching from the vcard/vevent formats to the opensync XML
33 - switching from storing state information in text files to
34 storing it in the built in database (optional)
35 - making use of the new opensync time APIs to properly support
36 timezones for all time operations
38 Switching away from text based vcard and vevent formats will remove
39 the burden of raw data parsing and formatting from the plugin itself,
40 and make use of the more tested opensync library. Any bugs fixed
41 in opensync's parsers will automatically fix bugs in the Barry plugin.
43 Switching state storage formats may allow for greater flexibility
44 in supporting multiple devices. This needs more research, but it
45 is the "way things are done" in opensync, and likely worth moving
48 Support for timezones will likely stress the opensync API as well as
49 the Barry API, but definitely needs to be done for completeness on both
50 sides of the equation.
52 Estimated time: simple way: 10 hours if lucky
53 proper way: open ended
57 Adding support for Tasks database to opensync plugin
58 ----------------------------------------------------
59 This will require research into the proper vformat for tasks. If
60 the above port to 0.40 is complete, then use the XML format. If not,
61 then find the appropriate v-format.
63 Estimated time: 16 hours
64 Depending on: ideally, wait for 0.40 XML format support
68 Adding support for Memos (notes) to opensync plugin
69 ---------------------------------------------------
70 Same as above, for Tasks. If done together, may be able to save some time.
72 Estimated time: 16 hours
73 Depending on: ideally, wait for 0.40 XML format support
77 Reverse engineering java loader protocol
78 ----------------------------------------
79 This has not been done by any opensource Blackberry project out there,
80 to my knowledge, and would be most useful to Blackberry application
83 If you are a Blackberry app developer, this may interest you.
85 Estimated time: open ended
89 Adding GPRS / CDMA modem support
90 --------------------------------
91 Barry has had plans to include modem support for a few months now, but
92 it has not yet percolated to the surface.
94 The primary source for modem protocol specifics is the XmBlackBerry
95 project (http://sourceforge.net/projects/XmBlackBerry). Barry's
96 goal is to create a standalone pppob utility that can be configured
97 with pppd similarly to pppoe.
99 The tricky part of modem support is that it requires threading support,
100 especially if you intend to use the database at the same time.
101 This leads to some architectural challenges that need to be dealt with:
103 As Barry is not a single application, how do you access the
104 database while pppob is using the modem?
106 There are two viable ways of dealing with this. One involves placing
107 a (hopefully thin) driver in the kernel, and the other involves using
108 a daemon and RPC calls.
110 My preference is to implement this using RPC calls if needed, and hammer
111 out all the implementation details in user space. Once they are well
112 understood, a smaller kernel driver hook may be more easily written
113 that supports routing messages according to socket or application
114 needs. For example, one application may register an interest in
115 database messages, another in javaloader messages, and another in the
116 multiple modem socket messages.
118 There is currently a development branch in CVS that intends to support
119 optional threading support in the Barry library, so that at least
120 it should be possible to use both the database and the modem in the
123 Estimated tasks (assuming threading support is finished):
124 - copy protocol specifics from XmBlackBerry
125 - add Serial class for controller interface
126 - write and test pppob
127 - write pppob manpage
128 Estimated time: 8 hours
132 Finish the threaded architecture changes in CVS branch
133 ------------------------------------------------------
134 For the reasons outlined above, for modem support, this CVS branch
135 needs to be finished. For more information, contact the mailing list.
138 - write SocketRouting code
139 - refactor the controller class into RAII behaving
140 mode classes, such as Desktop, Serial, and
141 Javaloader, that operate on top of Controller
142 - testing threaded and non-threaded behaviour
143 - testing performance impact
144 Estimated time: 20 hours
148 Add bluetooth serial support
149 ----------------------------
150 It is reported that it is possible to access the database through
151 Bluetooth using the older Blackberry serial protocol. XmBlackBerry
152 has support for this and may be used as a reference.
154 The goal here would be to hide the bluetooth access behind the
155 same Barry library API, so that syncing with the opensync plugin
156 would be seamless whether plugged in via USB or Bluetooth.
159 - research and design serial protocol stack to reuse as much
160 library code as possible
161 Estimated time: unknown
165 Write simple GUI for streamlining sync setup and action
166 -------------------------------------------------------
167 Syncing setup and operation is currently a tedious, complicated task.
168 A GUI that performed all the detailed setup and configuration work,
169 for a Blackberry-specific sync, using opensync libraries and plugins
170 for Evolution, Sunbird, etc, would be very helpful.
172 This would be much easier for an experienced GUI programmer, but there is
173 a learning curve for the opensync API.
176 - document the settings required for Blackberry, and
177 all intended plugins required
178 - write application that:
179 - does the opensync configuration through the opensync
181 - scans the USB bus for available Blackberry devices using
183 - lives in the system tray watching for Blackberry devices
184 - if aiming for super ease of use, script a source build of
185 all needed opensync components and install in private
186 area to avoid conflict with system
187 Estimated time: unknown
188 Note: Depending how fast HAL, OpenSync, and Conduit are implemented,
189 this may never be needed... but if it existed today, there's a
190 lot of users who would be very happy...
194 Document the USB protocol
195 -------------------------
196 Currently the only english documentation for the Blackberry protocol
197 is the webpage by the Cassis project (found at
198 http://off.net/cassis/protocol-description.html).
200 The USB protocol is not nearly so well documented. The best documentation
201 available can be found in the Barry header files: protocol.h and
204 Translating the code into documentation (into a wiki, that will hopefully
205 soon be available) is a great way to get involved in the project and
206 learn a lot about the Blackberry from a low level.
208 Unfortunately, Jedi mind tricks don't often work when trying to convince
209 people to write documentation for me... :-)
212 - write, write, write
213 Estimated time: 40 hours (documentation expands to fill available time...)
219 Code can always be improved. There are two big ways to help:
221 - write an application using the Barry library
222 - improve the Barry library itself and send patches
224 By writing an application, you can provide crucial feedback on the ease
225 of use of the Barry API. I'm very eager for such feedback.
227 Secondly, there is currently a lot of code ducplication in the record
228 classes, and a careful refactoring is required. I would be open to a class
229 hierarchy, with possibly private or protected inheritance. My primary
230 concern is object safety when using the record classes as objects in
231 STL containers, with a secondary concern to make it easier to
232 abstractly work with a record. This implies a careful mix of
233 virtual functions and a generic record base class. Patches in this
234 area will be thoughtfully considered.
236 Estimated tasks (refactoring):
237 - design safe hierarchy
238 - move common code to base class
239 - make sure all record classes use the common record API
241 Estimated time: 7 hours
247 For those that write applications in C, a C API wrapper has been started
248 in the cbarry.h header. It has not yet been implemented, but should be
252 - finish some API design work (head not fully complete)
253 - implement all functions (about 50)
254 - write test application, or test suite, for C API
255 Estimated time: unknown
259 Python wrappers and example code
260 --------------------------------
261 For those that write applications in Python, a SWIG wrapper has been
262 started by H Miz Jones. This is partially functional, and involves
263 working with the Barry API, and may introduce changes to it depending
264 how hard it is to translate things to the Python world.
266 The SWIG wrapper scripts have not yet been publically released, but
267 please contact me if you are interested.
270 - finish C++ / Python integration (possible template issues)
271 - finish SWIG wrapper
272 Estimated time: unknown
276 Command line backup and restore
277 -------------------------------
278 The only command line backup currently available is the one in btool,
279 using the -f and -s switches. This does not backup exact data from
280 the device, but parses it, stores it in the Boost serialization format,
281 and then reverses the process for restore. This is a great test
282 for the Barry library, but not so great for backup, since not all
283 databases can be parsed.
285 There is already an exact backup and restore interface with the GUI, but
286 there is a lot of useful functionality trapped in a layer of GUI
287 that could be just as useful from the command line. Tasks such as a nightly
288 cron backup of any Blackberry devices attached to the system would be more
289 easily done via command line.
291 You could add command line arguments to the barrybackup program to skip
292 the GUI (tricky and possibly error prone), or you could pull the backup
293 functionality into a standalone command line utility (more work, but smarter
294 in the long run). This is mostly a code refactoring job, consisting of
295 all working code that's already there, and I know there are people
296 who would thank you. :-)
299 - split out tar and backup functionality code into shared library
300 - write and test command line tool
301 Estimated time: 6 hours
305 Misc Low Level Todo Items:
306 --------------------------
307 - test whether sorting of contact records is required before
308 uploading data to the device... test whether it is ok
309 to upload a GroupLink item in the middle of a contact
310 upload, even before all the groups have been sent...
311 if ok, remove the sorting code from Contact, Message, and
