2 : �01[11:54] <@fardad> ericb2: Thank you in advance for taking time and lecturing us!
3 : [11:54] <@ericb2> To make things more easy, everything will be avaulable on the wiki afterwards
4 : [11:54] <@ericb2> fardad: you're welcome
5 : [11:55] <@ericb2> @all : if ever you detect something wrong, please let me know, or better fix it on the wiki afterwards
6 : [11:55] <@ericb2> thanks in advance
7 : [11:55] <@ericb2> Outline of the ClassRoom :
8 : [11:55] <@ericb2> 1) Create patches using svn
9 : [11:55] <@ericb2> 2) apply a patch
10 : [11:55] <@ericb2> 3) rebuild a module
11 : [11:55] <@ericb2> 4) rebuild a module including symbols
12 : [11:55] <@ericb2> 5) run OOo with gdb (introduction of gdb use)
13 : [11:55] <@ericb2> that's what we'll try to do
14 : [11:56] <@ericb2> if you have questions, please do
15 : [11:56] <@ericb2> fardad: we have ~1 hour
16 : [11:56] <@ericb2> fardad: is it ok ?
17 : [11:56] <IZBot> News from cws: native222: nominated || hr59: nominated
18 : �01[11:56] <@fardad> ericb2: sure, but just letting you know that students have 1hour 30 minutes
19 : [11:57] <@ericb2> fardad: well, they will experiment and ask then :-)
20 : [11:57] <@ericb2> Introduction : in this part, we will create, apply patches using svn tool. To simplify, we'll suppose the patches are in unified mode.
21 : [11:57] <@ericb2> Means:
22 : [11:57] <@ericb2> - 3 lines of context before the change
23 : [11:57] <@ericb2> - a line who starts with " - " means the line before the old version (if the old version was existing)
24 : [11:57] <@ericb2> - a line starting with " + " means after the change(s), if a new version does exist
25 : [11:57] <@ericb2> - 3 lines of context after the change
26 : [11:58] <@ericb2> The most important with unified mode : patches are human readable
27 : [11:58] <@ericb2> For example :
28 : [11:58] <@ericb2> ordinateur-de-eric-b-2:~/Desktop/ecntablet01 ericb$ svn diff sd/source/ui/slideshow/slideshow.hrc

51 : [11:59] <@ericb2> Lot of possibilities. Below some of them. Probably better solutions do exist. This is just a little inventory of the possibilities.
52 : [11:59] <@ericb2> 1.1) you got a tree, did some modifications, and you want to send the patch to a friend
53 : [12:00] <@ericb2> To visualize the changes :
54 : [12:00] <@ericb2> ordinateur-de-eric-b-2:~/Desktop/moz2seamonkey01 ericb$ svn diff slideshow/source/inc/userpainteventhandler.hxx
55 : [12:00] <@ericb2> The command (without the prompt) is :
56 : [12:00] <@ericb2> svn diff slideshow/source/inc/userpainteventhandler.hxx
57 : [12:00] <@ericb2> Comment: we only check the changes in 1 filme there
58 : [12:00] <@ericb2> The result is :

79 : [12:02] <achan66> okay thanks
80 : [12:02] <@ericb2> achan66: you're welcome :)
81 : [12:02] <@ericb2> 1.2) you want to create a patch between a cws and a milestone (the one the cws is based on )
82 : [12:02] <@ericb2> For example, to extract the changes in helpcontent2, ab65 introduced
83 : [12:03] <@ericb2> ab65 is the cws name, and was based on DEV300_m35
84 : [12:03] <@ericb2> in one line :
85 : [12:03] <@ericb2> svn diff http://svn.services.openoffice.org/ooo/tags/DEV300_m35/helpcontent2 http://svn.services.openoffice.org/ooo/cws/ab65/helpcontent2 > mydiff.diff
86 : [12:04] <@ericb2> Comment : as you can see, we use URLs, means you need a working internet connexion, and subversion installed :-)
87 : [12:04] <@ericb2> Important: for the eventual commiters, svn 1.5.4 or more is *mandatory* to avoid creating garbage in the dev tree :)
88 : [12:04] <@ericb2> 1.3) you want to create a patch between two svn revisions for a given cws
89 : [12:05] <@ericb2> Tip : you can follow the recent commits there : http://cia.vc/stats/project/OOo
90 : [12:05] <Kamots> ab65 is the cws name, and was based on DEV300_m35
91 : [12:05] <@ericb2> Example of change (in one line) :
92 : [12:05] <@ericb2> Kamots: exactly
93 : [12:05] <@ericb2> svn diff http://svn.services.openoffice.org/ooo/cws/ooo31gsl2/vcl@268180 http://svn.services.openoffice.org/ooo/cws/ooo31gsl2/vcl@268182
94 : [12:05] <Kamots> oh sorry! my mouse slipped
95 : [12:06] <@ericb2> Remark : the revision syntax is @number
96 : [12:06] <@ericb2> Other possible syntax : dates are allowed
97 : [12:06] <@ericb2> 1.4) using svn log, you want to create the diff between two revisions of the same file
98 : [12:07] <@ericb2> For example :
99 : [12:07] <@ericb2> ordinateur-de-eric-b-2:~/Desktop/moz2seamonkey01 ericb$ svn log configure.in
100 : [12:07] <@ericb2> Means: I'm working in moz2seamonkey01 tree ( svn info will confirm )
101 : [12:08] <@ericb2> Just some of the returned lines :
102 : [12:08] <@ericb2> (because the log is very long for some often modified files )

110 : [12:10] <@ericb2> lol :)
111 : [12:10] <@ericb2> Practice : try to find the command line yourself ;)
112 : �01[12:10] <@fardad> :)
113 : [12:10] <@ericb2> That's enough for the first part, about create a diff
114 : [12:11] <@ericb2> and other possibilities do exist. What I wanted to show, is you'll have to experiment by yourself, and choose the most adapted to your case
115 : [12:11] <@ericb2> questions ?
116 : [12:12] <jPau> nope
117 : [12:12] <Kamots> so there is no patch command that will generate a .patch file for all modified files?
118 : [12:12] <daeseon_> no
119 : [12:12] <BartB> no questions here
120 : [12:13] <@ericb2> Kamots: diff or svn diff will create a patch. Patch is the next part, and this command will *apply* it
121 : [12:13] <achan66> ic, so far none
122 : [12:13] <@ericb2> I'd like to add an important information
123 : [12:14] <@ericb2> .diff or .patch are the most used suffixes
124 : [12:14] <l_zahir> what happens when a patch fails to be applied?
125 : [12:14] <Kamots> oh ok, thank you
126 : [12:14] <@ericb2> the reason is simple
127 : [12:14] <@ericb2> some editors, when they read .diff or .patch extension, have colored syntax, what is basically interesting
128 : [12:15] <@ericb2> means: you are free to rename your patch whatever you want, but use .diff or .patch as suffix, is generally a good idea
129 : [12:15] <@ericb2> l_zahir: I'll treat the case
130 : [12:15] <@ericb2> l_zahir: in the second part.
131 : [12:15] <l_zahir> ok thanks
132 : [12:16] <WFred__> does this apply to non-C++ code such as PERL??
133 : [12:16] <@ericb2> WFred__: so far, diff can diff everything
134 : [12:16] <WFred__> :D
135 : [12:16] <@ericb2> WFred__: just use -a when you are diffing binary files
136 : [12:16] <@ericb2> WFred__: just try
137 : [12:17] <WFred__> what does the -a option do?
138 : [12:17] <@ericb2> WFred__: in OOo source tree we have makefiles, C++ , Java, Python , whatever
139 : [12:17] <@ericb2> WFred__: even .jpg or binaries blobs
140 : [12:18] <@ericb2> WFred__: man diff told me " treat all files as text"
141 : [12:18] <@ericb2> WFred__: usefull when binaries are diff'ed
142 : [12:18] <WFred__> oh ok thanks
143 : [12:18] <@ericb2> WFred__: to be sure, you can use diff -Naur old_tree new_tree
144 : [12:19] <@ericb2> WFred__: more precisely : diff -Naur old_tree new_tree W > my_patch.diff
145 : [12:19] <@ericb2> Part 2 :
146 : [12:19] <@ericb2> Apply a patch
147 : [12:19] <@ericb2> Essential options :
148 : [12:19] <@ericb2> --dry-run : fakes the patch application *extremely usefull* if you want to check whether a patch will apply, without create garbage in your tree
149 : [12:20] <@ericb2> -R : reverse it -> we suppose you already applied the patch, did no change and want to reverse the patch, to retrieve the same code as before
150 : [12:20] <@ericb2> -p0 : apply a patch using the exact path the files have. Important: your tree does match with the path of the file the patch will be applied, *AND*
151 : [12:20] <@ericb2> you apply it from the right location
152 : [12:20] <@ericb2> -p1 : you remove the first subdir of the path for every to be patched file listed in th patch
153 : [12:21] <@ericb2> -p2 you remove two .. and so on
154 : [12:21] <@ericb2> Correct way of application :
155 : [12:21] <@ericb2> Fake the application :
156 : [12:21] <@ericb2> patch --dry-run -p0 < my_patch.diff
157 : [12:21] <@ericb2> If nothing wrong occurs, remove the --dry-run option, and apply it for true :
158 : [12:21] <@ericb2> patch -p0 < my_patch.diff
159 : [12:22] <@ericb2> Other possibility, not recommended because of the UUOC (useless use of cat) :
160 : [12:22] <@ericb2> cat my_patch.diff | patch -p0
161 : [12:22] <@ericb2> Now, something important, people do not understand easely
162 : [12:22] <@ericb2> Depth of the application:
163 : [12:22] <@ericb2> e.g. let's suppose a patch has to modify
164 : [12:23] <@ericb2> vcl/source/aqua/source/window/salframeview.mm
165 : [12:23] <@ericb2> vcl/source/aqua/source/gdi/salprn.cxx
166 : [12:23] <@ericb2> vcl/source/aqua/inc/salframeview.h
167 : [12:23] <@ericb2> You can apply the patch from :
168 : [12:23] <@ericb2> 1) the root of the sources :
169 : [12:23] <@ericb2> patch -p0 < my_patch.diff
170 : [12:23] <@ericb2> 2) inside vcl :
171 : [12:23] <@ericb2> but you have to remove the first element of the path for every patched file
172 : [12:24] <@ericb2> patch -p1 < my_patch.diff
173 : [12:24] <@ericb2> (was -p0)
174 : [12:24] <@ericb2> 3) inside vcl/aqua
175 : [12:24] <@ericb2> patch -p2 < my_patch.diff
176 : [12:24] <@ericb2> BUT ...
177 : [12:24] <@ericb2> You cannot apply patch from elsewhere, because the paths will no longer match with the one every of the file contained in it.
178 : [12:25] <@ericb2> Other case
179 : [12:25] <@ericb2> 3) mix of applying patches + svn use
180 : [12:25] <@ericb2> e.g. you did a wrong change in a module, and you want to reverse it directly :
181 : [12:25] <@ericb2> cd module
182 : [12:25] <@ericb2> svn diff apath/afile.cxx | patch -R -p0
183 : [12:25] <@ericb2> will reverse the bad changes
184 : [12:25] <@ericb2> Other similar case :
185 : [12:26] <@ericb2> for the entire local tree this time
186 : [12:26] <@ericb2> svn diff . | patch -R -p0
187 : [12:27] <@ericb2> I'm sorry, but I'll have to stop for 15 to 20 minutes.
188 : [12:27] <@ericb2> So I ask you to prepare questions, experiment and so on for when I'll be back
189 : [12:27] <@ericb2> ok ?
190 : �01[12:27] <@fardad> thanks...
191 : �01[12:27] <@fardad> will do

193 : �01[12:28] <@fardad> thats very ok, this give us time to digest the info.... cu in 20

201 : [12:47] <l_zahir> for this problem:

203 : [12:47] <l_zahir> sorry this:
204 : [12:47] <l_zahir> http://daeseonmoon.wordpress.com/2009/02/02/build-openoffice-phase-2-rhino-build-fail-with-openjdk/
205 : [12:48] <@ericb2> l_zahir: this patch does have *extra* names in the path
206 : [12:49] <l_zahir> ok , I looked for the file and found them
207 : [12:49] <daeseon_> ericb2: so we need to use -p option
208 : [12:49] <@ericb2> l_zahir: so, what you have to do is 1) use -p option, with the right value AND apply the patch from the right place
209 : [12:49] <@ericb2> daeseon_: mandatory there
210 : [12:50] <l_zahir> is right place always one directory above the file?
211 : [12:50] <l_zahir> cause I noticed every body doing that
212 : [12:50] <l_zahir> <../
213 : [12:51] <@ericb2> l_zahir: I think you can put the patch in rhino, and try to apply it directly, using -p0
214 : [12:51] <l_zahir> ok
215 : [12:51] <@ericb2> l_zahir: to be sure, I test with m40
216 : [12:51] <l_zahir> does the patch fail if the line numbers do not match the file?
217 : [12:52] <l_zahir> thanks
218 : [12:52] <l_zahir> cause the patch fails (half of it )
219 : [12:52] <@ericb2> l_zahir: Please excuse me
220 : [12:53] <@ericb2> l_zahir: the patch must be applied using -p1 fomr inside rhino, and using -p0 from the root dir
221 : [12:53] <l_zahir> and I tried to apply it manually but the out come wouldn't make sense and laft me with open xml tags
222 : [12:53] <l_zahir> ok
223 : [12:53] <l_zahir> I did not use any -p
224 : [12:53] <@ericb2> l_zahir: in fact only -p0 from the root dir works
225 : [12:53] <@ericb2> l_zahir: and the patch gives garbage
226 : [12:53] <@ericb2> l_zahir: now to answer to your previosu question, a patch can cause disorder
227 : [12:53] <l_zahir> but the location of the code lines were wrong too
228 : [12:54] <l_zahir> ok
229 : [12:54] <@ericb2> l_zahir: yes, the patch does not apply, but I'll create a new one for you (if I can now)
230 : [12:54] <l_zahir> :)
231 : [12:54] <l_zahir> than you
232 : [12:54] <@ericb2> l_zahir: to summarize :
233 : [12:54] <@ericb2> patch --dry-run -p0 < buildfix-openjdk-6-no-rhino.diff
234 : [12:54] <@ericb2> is the right way to apply it
235 : [12:54] <@ericb2> but
236 : �01[12:55] <@fardad> ericb2: everyone is LOLing :)
237 : [12:55] <@ericb2> fardad: why ?
238 : [12:55] <mmu_man> our minister of culture looks nice on this pic: http://www.laquadrature.net/fr/hadopi-albanel-passe-son-oral-0-sur-20
239 : �01[12:55] <@fardad> ericb2: they are amazed that you can just fix the patch "right now"
240 : [12:55] <mmu_man> she likes DRM so probably doesn't like OOo :-(
241 : [12:56] <@ericb2> fardad: I'll try. This happens form time to time
242 : [12:56] <l_zahir> and I spent 3 days non stop and could not get it writ :(
243 : [12:56] <l_zahir> right
244 : [12:56] <@ericb2> two problems with this patch :

249 : [12:56] <IZBot> News from cws: hb17: nominated || fwk102: nominated || native226: nominated
250 : [12:57] <@ericb2> saying something not clean happened
251 : [12:57] <@ericb2> + the bad message :
252 : [12:57] <@ericb2> patching file scripting/java/build.xml
253 : [12:57] <@ericb2> Hunk #1 FAILED at 85.
254 : [12:57] <IZBot> no issue with number 1
255 : [12:57] <@ericb2> saying the result will be put in
256 : [12:57] <@ericb2> 1 out of 1 hunk FAILED -- saving rejects to file scripting/java/build.xml.rej
257 : [12:58] <@ericb2> to fix that, we need to apply it for true, and see what happened
258 : [12:58] <@ericb2> to the one who don't know how to proceed
259 : [12:59] <@ericb2> patches are created with the building environment
260 : [12:59] <l_zahir> the fixes to scripting/java/build.xml in the patch aws not clear for me
261 : [12:59] <@ericb2> e.g. on Mac OS X source MacOSXX86Env.Set.sh
262 : [12:59] <@ericb2> then, you have to go into rhino
263 : [12:59] <@ericb2> and type :
264 : [13:00] <@ericb2> dmake patch
265 : [13:01] <@ericb2> then, apply the changes you are supposed to apply in the new patch in the output tree -> unxmacxi.pro there
266 : [13:01] <@ericb2> (I'll continue after)
267 : [13:01] <@ericb2> then do :
268 : [13:01] <@ericb2> (once the changes are ok): :
269 : [13:01] <@ericb2> dmake create patch
270 : [13:01] <@ericb2> sorry
271 : [13:01] <@ericb2> dmake create_patch
272 : [13:01] <@ericb2> this command will create a new patch, replacing the previous one and including all the changes you did manually
273 : [13:01] <@ericb2> that's all
274 : [13:03] <@ericb2> l_zahir: now, maybe the change is obsolete, means cannot be applied. I'm not an .xml specialist, but I can have a look
275 : [13:03] <l_zahir> I would appreciate that
276 : [13:05] <l_zahir> So each successful Hunk means that 1 file has been modified? Or a part of a file?
277 : [13:05] <@ericb2> l_zahir: can be a part of a file, when several changes occur in the same file
278 : [13:05] <@ericb2> l_zahir: means it depends
279 : [13:05] <l_zahir> ok
280 : [13:06] <l_zahir> and after applying each patch should we dmake clean and build again?
281 : [13:06] <l_zahir> or we shoul apply all the patches from the beginning to the source code ?
282 : [13:06] <@ericb2> l_zahir: dmake create_patch will create a backup of the previous one ( .bak ) and build should be ok
283 : [13:07] <l_zahir> Ok , thanks
284 : [13:07] <@ericb2> l_zahir: no, so far, when you are inside a module, you just have to build it : build does it (supposing you sourced the environment file)
285 : [13:07] <@ericb2> l_zahir: deliver at the end, to put everything in the solver
286 : [13:07] <@ericb2> l_zahir and then you can continue the build
287 : [13:08] <@ericb2> l_zahir: back to this patch, the change look completely uncompatible
288 : [13:08] <l_zahir> yes but it worked for others
289 : [13:09] <@ericb2> l_zahir: interesting. Do you remember the milestone used for the build ?
290 : [13:09] <l_zahir> 40 and 41
291 : [13:10] <@ericb2> l_zahir: did the patch apply without garbage ?
292 : [13:10] <l_zahir> Daeseon did it manually
293 : �01[13:10] <@fardad> ericb2: intersting to know that for both build daeseon_ applied the patched manually :)
294 : [13:10] <l_zahir> but I couldn't
295 : [13:10] <l_zahir> He is the smartest here
296 : [13:11] <@ericb2> daeseon_: can yo please tell me more : did it break, then you applied the patch ? Or did you proceed differently ?
297 : [13:12] <daeseon_> ericb2:I saw the patch files and open the file which need to be changed using vi
298 : [13:12] <daeseon_> and then manuall I made change
299 : [13:12] <@ericb2> daeseon_: ok, then you fixed it manually
300 : [13:12] <@ericb2> daeseon_: that's the only solution I see
301 : [13:12] <daeseon_> ericb2:yes. I didn't know how to create patch file and
302 : [13:13] <@ericb2> daeseon_: ok, no problem
303 : [13:13] <daeseon_> how to apply patch using patch command
304 : [13:13] <daeseon_> Now I know...
305 : [13:13] <@ericb2> what I propose : I'll continue after with the patch and I'll finish the presentation. Still a little part to say
306 : [13:13] <@ericb2> ok ?
307 : [13:14] <l_zahir> Daeseon:good you did not know, otherwise you would be confused :)
308 : �01[13:14] <@fardad> ericb2: now that daeseon_ patched it and it worked, can't he diff the files and recreate the proper patch?
309 : �01[13:14] <@fardad> ericb2: sorry, please continue...
310 : [13:14] <@ericb2> fardad: yes, he can , but he'll have to backup the modified file, cleanup the tree, and restart dmake patch .. replace the modified files .. dmake create_patch
311 : [13:15] <@ericb2> fardad: thanks :) We suppose now we did a change, applied whatever patch
312 : [13:15] <@ericb2> Next part is :
313 : [13:15] <@ericb2> 4) Rebuild a module where a patch has been applied
314 : [13:15] <@ericb2> 4.1. Introduction
315 : [13:15] <@ericb2> We suppose we modified some files, and we need to rebuild a lib. The scheme is always the same, in every module concerned by the build
316 : [13:15] <@ericb2> - the first prj/build.lst does contain the modules dependencies, means all the listed modules are prerequisites
317 : [13:16] <@ericb2> - everything built inside a module is put in type_os_proc.pro
318 : [13:16] <@ericb2> e.g. on Mac OS X, type == unx , os == macx , I for Intel -> output dir is unxmacxi.pro in every module
319 : [13:17] <@ericb2> Note: have a look in solenv/inc -> all the possible arch/os have their own makefile, containing the essential for the build. unxlngi4.mk unxmacxi.mk unxmacxp.mk .. and so on : everything is there
320 : [13:17] <@ericb2> The last modification date is used to check the dependencies.
321 : [13:17] <@ericb2> Rule : If a .o is older than it's dependencies, it is rebuild
322 : [13:17] <@ericb2> -> once you modified a file ( touch file is enough) , build in a module will create a new lib
323 : [13:17] <@ericb2> or more generally, new binaries
324 : [13:18] <@ericb2> 4.2 ) Example : rebuild libvclmxi.dylib on Mac ( .so on Linux, .dll on Windows )
325 : [13:18] <@ericb2> Hypothesis : we suppose the build is completed, and successfull.
326 : [13:18] <@ericb2> cd vcl
327 : [13:18] <@ericb2> touch aqua/source/gdi/sallayout.cxx
328 : [13:18] <@ericb2> -> even without a change, the matching .o will be rebuilt
329 : [13:19] <@ericb2> build
330 : [13:19] <@ericb2> ! not dmake inside a module
331 : [13:19] <@ericb2> but dmake can be used in a subdir containing a makefile.mk file
332 : [13:20] <@ericb2> e.g. dmake test will build whatever respecting the target "test" if there is one existing in the makefile.mk file located in the current dir
333 : [13:20] <@ericb2> Other tip :
334 : [13:20] <@ericb2> If you are in aqua/source/gdi , and you want to rebuild *only* the files listed in the makefile in the current dir, do :
335 : [13:20] <@ericb2> dmake killobj
336 : [13:20] <@ericb2> build
337 : [13:20] <@ericb2> Once done, and if you want to see the changes packaged, do : deliver
338 : [13:21] <@ericb2> cd ../instsetoo_native
339 : [13:21] <@ericb2> mv unxmacxi.pro
340 : [13:21] <@ericb2> unxmacxi.pro_back
341 : [13:21] <@ericb2> (in one line)
342 : [13:21] <@ericb2> build
343 : [13:21] <@ericb2> will recreate a new installset
344 : [13:21] <@ericb2> Else, if you just want to test your lib, put it in the right subdir
345 : [13:21] <@ericb2> (probably in <Install_dir>/OpenOffice.org.app/Contents/basis-link/program on Mac OS X )
346 : [13:22] <@ericb2> same for any binary, or resource file ( .res ) when you modify the layout
347 : [13:22] <@ericb2> Now, we'll start the gdb part
348 : [13:22] <@ericb2> 5 ) Build including symbols.
349 : [13:22] <@ericb2> Example
350 : [13:22] <@ericb2> cd vcl
351 : [13:23] <@ericb2> mv unxmacxi.pro unxmacxi.pro_back # keep the normal build
352 : [13:23] <@ericb2> build debug="a_non_empty_sting" # means " build debug=t " is ok
353 : [13:23] <@ericb2> The final lib, including symbols for debugging, will be in unxmacxi.pro/lib (on Mac OS X )
354 : [13:23] <@ericb2> Replace the one already in <Install_dir>/OpenOffice.org.app/Contents/basis-link/program on Mac OS X
355 : [13:23] <@ericb2> and the last thing for today (will prepare the next presentation) :
356 : [13:23] <@ericb2> To debug using gdb,do :
357 : [13:23] <@ericb2> cd <Install_dir>/OpenOffice.org.app/Contents/program
358 : [13:23] <@ericb2> gdb --args soffice apath/afile
359 : [13:23] <@ericb2> "r" (to start) .. and so on;
360 : [13:23] <@ericb2> Happy debugging !
361 : [13:24] <@ericb2> Sorry for being long, but that's all for today :)

366 : [13:25] <l_zahir> Thanks
367 : [13:25] <tct13> i'm the romanian from fosdem that stated the implication of its organization in openoffice education
368 : [13:25] <Kamots> hello
369 : [13:25] <@ericb2> l_zahir: you're welcome
370 : [13:25] <Kamots> thank you very much eric
371 : [13:25] <@ericb2> tct13: hello :)
372 : [13:25] <tct13> :-)
373 : [13:25] <@ericb2> Kamots: you're welcome
374 : [13:25] <BartB> ericb2: where on the wiki will all of this be posted?
375 : [13:26] <@ericb2> @all : http://wiki.services.openoffice.org/wiki/Education_ClassRoom/Practice#SVN_use
376 : [13:26] <achan66> yey thanks
377 : [13:26] <achan66> i was gonna ask that
378 : [13:26] <@ericb2> I'll complete once possible
379 : [13:26] <@ericb2> this is not perfect, and everybody is welcome to improve, and add information !
380 : [13:26] <@ericb2> thanks in advance
381 : [13:26] <@ericb2> :-)
382 : [13:27] <BartB> thank you
383 : [13:27] <daeseon_> thank you eric. It is really useful.
384 : [13:27] <@ericb2> l_zahir: I'll have a look at your patch
385 : [13:27] <@ericb2> daeseon_: you're welcome :)
386 : [13:27] <tct13> me and my associate continued the discussion with Sun officials. we plan a Sun event at the very beginning of the Campus Ambassador programme, at the end of February
387 : [13:27] <@ericb2> tct13: great.
388 : [13:27] <l_zahir> thank you , I'm looking forward to the result
389 : [13:27] <tct13> meanwhile, we document on ooo developing from education.ooo
390 : [13:27] <tct13> :-D
391 : [13:28] <@ericb2> l_zahir: just be a bit patient: it will be dinner time. But I'll be there afterwars
392 : [13:28] <@ericb2> afterwards
393 : [13:28] <l_zahir> :)
394 : [13:28] <l_zahir> thanks
395 : [13:28] <@ericb2> tct13: just to avoid misunderstanding: Sun does not provide me any information. Means does not really share ;)
396 : [13:28] <tct13> ericb2: just wanted to let you know, we'll probably ask some questions this days
397 : �01[13:29] <@fardad> ok, this ends the session for today, thanks again and see you on thursday same time :)
398 : [13:29] <tct13> well, this is why I told you :-)
399 : [13:29] <@ericb2> l_zahir: the probem you could have, is a working patch can be created, but can break the build
400 : [13:29] <@ericb2> tct13: thanks :)
401 : [13:29] <@ericb2> tct13: can we continue in say, 1h30 ?
402 : [13:29] <l_zahir> yes
403 : [13:29] <tct13> sure :-)
404 : [13:29] <@ericb2> tct13: I'm sorry, this is dinner time
405 : [13:29] <tct13> i already had
406 : [13:29] <@ericb2> tct13: ok, then later :)
407 : [13:29] <tct13> gmt + 2 :-P
408 : [13:29] <tct13> ok
409 : [13:30] <@ericb2> tct13: I'm sorry, but I really will have to stop
410 : [13:30] <tct13> bone a petit
411 : [13:30] <l_zahir> ericb2: have a good day
412 : [13:31] <Kamots> thanks again, take care everyone
413 : [13:31] <@ericb2> thanks to all :-)
