Introduction :  in this part, we will create, apply patches using svn tool. To simplify, we'll suppose the patches are in unified mode. Means:
 +
 +
- 3 lines of context before the change
 +
 +
- a line who starts with " - " means the line before the old version (if the old version was existing)
 +
 +
- a line starting with " + " means after the change(s), if a new version does exist
 +
 +
- 3 lines of context after the change
 +
 +
 +
For example :
 +
 +
ordinateur-de-eric-b-2:~/Desktop/ecntablet01 ericb$ svn diff sd/source/ui/slideshow/slideshow.hrc

==== Create patches using svn ====
 +
 +
Lot of possibilities. Below some of them. Probably better solutions do exist. This is just a little inventory of the possibilities.
 +
 +
* you got a tree, did some modifications, and you want to send the patch to a friend
 +
 +
=> The idea is to compare your current tree with the one *before* the changes.
 +
 +
 +
To visualize the changes :
 +
ordinateur-de-eric-b-2:~/Desktop/moz2seamonkey01 ericb$ svn diff slideshow/source/inc/userpainteventhandler.hxx
 +
 +
The command (without the prompt) is :
 +
 +
svn diff slideshow/source/inc/userpainteventhandler.hxx
 +
 +
The result is :
 +
<pre>
 +
Index: slideshow/source/inc/userpainteventhandler.hxx
 +

 +

 +
 +
To create the patch for true, the command is :
 +
svn diff slideshow/source/inc/userpainteventhandler.hxx > my pretty patch.diff
 +
 +
And " my_pretty_patch.diff " will contain the same.
 +
 +
 +
 +
* you want to create a patch between a cws and a milestone (the one the cws is based on )
 +
 +
For example, to extract the changes in helpcontent2, ab65 introduced
 +
 +
svn diff http://svn.services.openoffice.org/ooo/tags/DEV300_m35/helpcontent2 http://svn.services.openoffice.org/ooo/cws/ab65/helpcontent2 > mydiff.diff
 +
 +
 +
 +
* you want to create a patch between two svn revisions for a given cws
 +
 +
 +
IMPORTANT:  you can follow the recent commits there : http://cia.vc/stats/project/OOo
 +
 +
Example of change (in one line) : 
 +
 +
svn diff http://svn.services.openoffice.org/ooo/cws/ooo31gsl2/vcl@268180 http://svn.services.openoffice.org/ooo/cws/ooo31gsl2/vcl@268182
 +
 +
 +
* using svn log, you want to create the diff between two revisions of the same file
 +
 +
For example :
 +
 +
ordinateur-de-eric-b-2:~/Desktop/moz2seamonkey01 ericb$ svn log configure.in
 +
Enter passphrase for key '/Users/ericb/.ssh/id_dsa_ooo_svn':

==== Apply a patch ====
 +
 +
Essential options :
 +
 +
--dry-run : fakes the patch application *extremely usefull* if you want to check whether a patch will apply, without create garbage in your tree
 +
 +
-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
 +
 +
-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*
 +
you apply it form the right location
 +
 +
-p1 : you remove the first subdir of the path for every to be patched file listed in th patch
 +
 +
 +
Correct way of application :
 +
 +
Fake the application :
 +
 +
patch --dry-run -p0 < my_patch.diff
 +
 +
If nothing wrong occurs :
 +
 +
patch -p0 < my_patch.diff
 +
 +
 +
Other possibility, not recommended because of the UUOC (useless use of cat) : 
 +
 +
cat my_patch.diff | patch -p0
 +
 +
 +
Depth of the application:
 +
 +
e.g. let's suppose a patch has to modify  :
 +
 +
vcl/source/aqua/source/window/salframeview.mm
 +
vcl/source/aqua/source/gdi/salprn.cxx
 +
vcl/source/aqua/inc/salframeview.h
 +
 +
 +
You can :
 +
 +
apply the patch from
 +
 +
* the root of the sources :
 +
 +
patch -p0  < my_patch.diff
 +
 +
* inside vcl :
 +
 +
patch -p1 < my_patch.diff
 +
 +
* inside vcl/aqua
 +
 +
patch -p2 < my_patch.diff
 +
 +
 +
You cannot apply  patch from elsewhere, because the paths will no longer match with the one every of the file contained in it.
 +
 +
 +
* mix of applying patches + svn use
 +
 +
e.g. you did a wrong change in a module, and you want to reverse it directly :
 +
 +
cd  module
 +
 +
svn diff  apath/afile.cxx  | patch -R -p0
 +
 +
for the entire local tree :
 +
 +
svn diff .  | patch -R -p0
 +
 +
 +
==== Rebuild a module where a patch has been applied ====
 +
 +
* Introduction
 +
 +
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.
 +
 +
- the first prj/build.lst does contain the modules dependencies, means all the listed modules are prerequisites
 +
- everything built inside a module is put in type_os_proc.pro
 +
 +
e.g. on Mac OS X, type == unx ,  os == macx  ,  I for Intel -> output dir is unxmacxi.pro
 +
 +
Note:  have a look in solenv/inc  -> all the possible arch/os have their own makefile, containing the essential for the build.
 +
 +
 
 +
The last modification date is used to check the dependencies.
 +
 +
Rule : If a .o is older than it's depenencies, it is rebuild
 +
-> once you modified a file ( touch file is enough) , build in a module will create a new lib
 +
 +
*  rebuild libvclmxi.dylib on Mac ( .so on Linux, .dll on Windows )
 +
 +
Hypothesis : we suppose the build is completed, and successfull.
 +
 +
cd vcl
 +
touch aqua/source/gdi/sallayout.cxx
 +
build
 +
 +
If you are in aqua/source/gdi , and you want to rebuild *only* the files listed in the makefile in the current dir, do :
 +
 +
dmake killobj
 +
build
 +
 +
Once done, and if you want to see the changes packaged, :
 +
 +
deliver
 +
cd ../instsetoo_native
 +
build  # will rebuild a new installset
 +
 +
Else, if you just want to test your lib, put it in the right subdir
 +
(probably in <Install_dir>/OpenOffice.org.app/Contents/basis-link/program on Mac OS X )
 +
 +
 +
==== Build including symbols ====
 +
 +
Example
 +
 +
-> in vcl
 +
 +
cd vcl
 +
mv unxmacxi.pro unxmacxi.pro_back  # keep the normal build
 +
build debug="a_non_empty_sting"  #  means " build debug=t  "  is ok
 +
 +
The final lib, including symbols for debugging, will be in unxmacxi.pro/lib (on Mac OS X )
 +
 +
Replace the one  already  in <Install_dir>/OpenOffice.org.app/Contents/basis-link/program on Mac OS X
 +
 +
To debug using gdb,do :
 +
 +
cd  <Install_dir>/OpenOffice.org.app/Contents/program
 +
 +
gdb --args soffice apath/afile 
 +
 +
"r"  (to start) .. and so on;
 +
 +
Happy debugging !
 +
 +
=== gdb basics ===
 +
 +
FIXME : make the look of the log more .. appealing ;)
 +
 +
Candidates ?
 +
 +

 +
<font color=blue>Outline of the ClassRoom</font>
 +
 +
* Prerequisites for the test
 +
* Reminder about what happens when building in a module
 +
* Add symbols in a library
 +
* Introduction of gdb use
 +
* Launch OOo using gdb
 +
* Play with it (discovery)
 +
 +
 +
[18:05] ericb2 So today, we'll start playing with gdb + Ooo
 +
 +
[18:05] ericb2 who does have a full OOo build at hand ?
 +
 +
[18:06] ericb2 ok :)
 +
 +
[18:06] ericb2 As pre-requisites , I'll suppose :
 +
 +
[18:06] ericb2 - there is a complete build working already
 +
 +
[18:06] ericb2 - there is a working installset , and we will launch it using the terminal
 +
[18:06] ericb2 Thus, if you want to redo at home, or later, you just have to read and try
 +
 +
[18:07] ericb2 Reminder : what happens when something is built
 +
 +
[18:07] ericb2 we'll use <module> for whatever subdir of the OOo tree, aka "module" most of the time
 +
 +
[18:08] ericb2 <module>/prj/build.lst does contain the list of the subdirs containing a makefile
 +
 +
[18:08] ericb2 Means:  Every product is built in the output dir. e.g. : unxmacxi.pro on Mac Intel
 +
 +
[18:08] ericb2 we have the same tree inside all the modules:
 +
 +
[18:08] ericb2 unxmacxi.pro/bin
 +
 +
[18:09] ericb2 unxmacxi.pro/lib
 +
 +
[18:09] ericb2 unxmacxi.pro/inc
 +
 +
[18:09] ericb2 ... and so on (look yourself )
 +
 +
[18:09] ericb2 to rebuild a module, just remove this directory
 +
 +
[18:09] ericb2 Once all the .o are build, the libs, and/or the binaries / resources / whatever are  "delivered" from the unxmacxi.pro dir to
 +
the solver
 +
 +
[18:11] ericb2 The information providing the list of what has to be delivered is always in : <module>/prj/d.lst
 +
 +
[18:12] ericb2 these files are text files, using a "Windows"  separator, but this is not a problem at all
 +
 +
[18:12] * l_zahir (n=chatzill@142.204.16.10) has joined #education.openoffice.org
 +
 +
[18:13] ericb2 If we summarize : a normal build provides binaries like libraries, who are stripped when the are delivered. Between the
 +
unxmacxi.pro and their place in the "solver "
 +
 +
[18:14] ericb2 Important:  to be able to trace using gdb, we'll need to add symbols, lines of code and a lot of information inside the binaries
 +
 +
[18:14] ericb2 Howto add symbols in a library ? 
 +
 +
[18:14] ericb2 1) first approach
 +
 +
[18:15] ericb2 -> look at configure extra option : --disable-strip-solver
 +
 +
[18:15] ericb2 To verify by yourself, just place you at the root of the sources (since DEV300_m40, there is no longer config_office subdir)
 +
 +
[18:15] ericb2 and do : ./configure --help | grep -4 solver
 +
 +
[18:16] ericb2 you'll have several lines explaining the right option
 +
 +
[18:16] ericb2 Tip : if you're familiar with configure, better read configure itself, more informative ;-)
 +
 +
[18:17] ericb2 and if you know a bit of autoconf, you can even hack configure.in, and run autoconf to regenerate a new configure :)
 +
 +
 +
[18:18] ericb2 The first approach has a drawback : just a bit of information is inside the binary, and that's not enough most of the time,
 +
 +
when you have a complex problem to solve
 +
 +
 +
 +
[18:19] ericb2 2) second approach
 +
 +
[18:19] ericb2 consider only a part of the code, for tracing
 +
 +
[18:20] ericb2 The method is equivalent to use  --enable-debug at configure time, but nobody uses this option. the reason is simple : all
 +
libraries become huges, and OOo won't probably launch correctly.
 +
 +
[18:21] ericb2 e.g. : the libsw (writer) becomes 660MB heavy
 +
 +
[18:22] fardad ericb2: when you say correctly, does it mean it will be too slow, or it will not function properly?
 +
 +
[18:22] Kamots wow, that's a lot of extra weight
 +
 +
[18:23] ericb2 fardad: yes, imagine 10 libs of 500MB every + some other 100MB and so on
 +
 +
[18:23] ericb2 Kamots: I'll explain you how to proceed
 +
 +
[18:23] fardad wow, :o
 +
 +
[18:24] ericb2 Other important information
 +
 +
[18:24] ericb2 about assertions
 +
 +
[18:24] ericb2 There is another option in configure
 +
 +
[18:24] ericb2 --enable-dbgutil
 +
 +
[18:25] ericb2 Include additional debugging utilities, such assertions, object counting, etc. Larger build.
 +
 +
[18:25] ericb2   Independent from --enable-debug
 +
 +
[18:25] ericb2 the *second one* does concern assertions in the code :
 +
 +
[18:25] ericb2 DBG_ASSERT( !(rALR.flags & kATSGlyphInfoTerminatorGlyph),                                       
 +
 +
[18:25] ericb2                         "ATSLayout::InitGIA(): terminator glyph not marked as deleted!" );
 +
 +
[18:26] ericb2 -> if the condition is not verified -> boom .. and a window will appear, containing the message
 +
 +
[18:26] ericb2 if --enable-dbgutil is not in the configure command line, assertions are not included
 +
 +
[18:27] ericb2 As you understood, assertions are for development, not for end users ;-)
 +
 +
[18:27] ericb2 So, we use to add symbols for debugging for some libs, in a given module only
 +
 +
[18:27] ericb2 Counterpart : needs to rebuild the module
 +
 +
[18:28] ericb2 The process is very simple :
 +
 +
[18:28] ericb2 cd <module>
 +
 +
[18:28] ericb2 mv unxmacxi.pro unxmacxi.pro_backup
 +
 +
[18:28] ericb2 build debug=t
 +
 +
[18:28] ericb2 Do *always* a backup of your build, because the binaries in the output tree, do match with stamps in the solver
 +
 +
[18:29] ericb2 if you modify something, you'll have to redo a build, and a "deliver". Elser, the build can break at postprocess, or at then end,
 +
because the stamp between the solver and the module do not match
 +
 +
[18:29] ericb2 that's just harmless, but if you are not aware, you can lose a while before someone explains you what happens
 +
 +
[18:31] ericb2 As example, I'll rebuild a little lib , to show you the difference
 +
 +
[18:31] ericb2 cd apple_remote/
 +
 +
[18:32] ericb2 source ../MacOSXX86Env.Set.sh
 +
 +
[18:32] ericb2 sorry, I forgot :-)
 +
 +
[18:32] ericb2 mv unxmacxi.pro unxmacxi.pro_back
 +
 +
[18:32] ericb2 build debug=t
 +
 +
[18:32] ericb2 Important:  whatever you put, will work
 +
 +
[18:33] ericb2 t is one letter, but once the string is not empty, debug is true
 +
 +
[18:33] ericb2 means all the code included between #ifdef DEBUG ... #endif  or some other macros, will be included
 +
 +
[18:34] ericb2 e.g. :
 +
 +
[18:34] ericb2 #ifdef DEBUG                                                                                                     
 +
 +
[18:34] ericb2         // debug purpose                                                                                         
 +
 +
[18:34] ericb2     NSLog(@"reset... (after listening to remote)");                                                             
 +
 +
[18:34] ericb2 #endif
 +
 +
[18:34] ericb2 -> in the terminal, I'll see the information
 +
 +
[18:34] ericb2 NSLog is sort of cout
 +
 +
[18:35] fardad ic,
 +
 +
[18:35] ericb2 After the rebuild :
 +
 +
[18:35] ericb2 ls -l  unxmacxi.pro/lib/libAppleRemotemxi.dylib
 +
 +
[18:35] * lgodard has quit ("Leaving.")
 +
 +
[18:35] ericb2 -rwxr-xr-x  1 ericb  ericb  159932 Feb 19 18:31 unxmacxi.pro/lib/libAppleRemotemxi.dylib
 +
 +
[18:35] ericb2 ls -l unxmacxi.pro_back/lib/libAppleRemotemxi.dylib
 +
 +
[18:36] ericb2 -rwxr-xr-x  1 ericb  ericb  52436 Feb 12 14:31 unxmacxi.pro_back/lib/libAppleRemotemxi.dylib
 +
 +
[18:37] ericb2 the first one does contain strings and a lot of other stuff
 +
 +
[18:37] ericb2 Now .. Launch OOo in a terminal :)
 +
 +
[18:37] ericb2 before, we'll copy the lib in the bundle
 +
 +
[18:37] IZBot News from cws: native227: created
 +
 +
[18:38] ericb2 For the rest, my bundle is in the Desktop/test_eraser folder (I'm on Mac OS X )
 +
 +
[18:38] ericb2 Means, the Bundle is the dir : ~/Desktop/test_eraser/OpenOffice.org.app
 +
 +
[18:38] ericb2 So, I'll open a terminal, and I'll do :
 +
 +
[18:39] ericb2 cd ~/Desktop/test_eraser/OpenOffice.org.app/Contents/program
 +
 +
[18:39] ericb2 the idea, is to start gdb form the directory containing soffice (the binary )
 +
 +
[18:39] ericb2 and the command line is :
 +
 +
[18:40] ericb2 gdb --args ~/Desktop/est.odp
 +
 +
[18:40] ericb2 you'll see gdb tell you a lot of things. If you don't want to see that the next time, you can add -q (for quiet) option
 +
 +
[18:41] ericb2 as you can see nothing happens :)
 +
 +
[18:41] ericb2 the reason is: the binary is not "running"
 +
 +
[18:42] ericb2 oops, sorry
 +
 +
[18:42] ericb2 gdb --args soffice  ~/Desktop/est.odp
 +
 +
[18:42] ericb2 is the right command line
 +
 +
[18:42] ericb2 to redo; just enter "q"
 +
 +
[18:42] ericb2 and type the correct command
 +
 +
[18:43] ericb2 now, type r ( shortcut for "run" )
 +
 +
[18:43] ericb2 -> OOo will start
 +
 +
[18:43] ericb2 and open the file
 +
 +
[18:44] ericb2 in the terminal, you no longer have the control. To stop the execution, do "CTRL-C"
 +
 +
[18:44] ericb2 Program received signal SIGINT, Interrupt.
 +
 +
 +
[18:44] ericb2 0x90009cd7 in mach_msg_trap ()
 +
 +
[18:44] ericb2 (gdb)
 +
 +
[18:44] ericb2 OOo is stopped
 +
 +
[18:44] ericb2 you can enter whatever command, like " info frame "
 +
 +
[18:45] ericb2 to continue, type : c
 +
 +
[18:45] ericb2 The result is : (gdb) c
 +
 +
[18:45] ericb2 Continuing.
 +
 +
[18:45] ericb2 and OOo is no longer stopped
 +
 +
[18:45] ericb2 Add a breakpoint
 +
 +
[18:45] fardad amazing...
 +
 +
[18:46] ericb2 fardad: I know this is difficult like that, but people will redo later, and ask whenever they want
 +
 +
[18:46] ericb2 on the channel
 +
 +
[18:46] ericb2 we'll explain them
 +
 +
[18:46] fardad I understand
 +
 +
[18:47] ericb2 Let's add a breakpoint now
 +
 +
[18:47] ericb2 to know whether breakpoints are set or not, the command is :
 +
 +
[18:47] ericb2 info b 
 +
 +
[18:47] ericb2 (means info breakpoints)
 +
 +
[18:48] ericb2 exactly :
 +
 +
[18:48] ericb2 CTRL-C
 +
 +
[18:48] ericb2 info b
 +
 +
[18:48] ericb2 The result is :
 +
 +
[18:48] ericb2 (gdb) info b
 +
 +
[18:48] ericb2 No breakpoints or watchpoints.
 +
 +
[18:48] ericb2 of course
 +
 +
[18:48] ericb2 so let's set one
 +
 +
[18:49] ericb2 Since only libAppleRemotemxi.dylib has symbols, I'll have to set one in whatever file included
 +
 +
[18:49] ericb2 say RemoteMainController.m
 +
 +
[18:49] ericb2 We can either choose a method
 +
 +
[18:50] ericb2 Syntax :  b  'class:myMethod'
 +
 +
[18:50] ericb2 or at some line :
 +
 +
[18:50] ericb2 Syntax : b RemoteMainController.m:118
 +
 +
[18:50] ericb2 The result is :
 +
 +
[18:50] ericb2 (gdb) b RemoteMainController.m:118
 +
 +
[18:50] ericb2 Breakpoint 1 at 0x338e1ea: file RemoteMainController.m, line 118.
 +
 +
[18:51] ericb2 and using the up/down arrow, the history is available (no need to type several times the same command ;) 
 +
 +
[18:51] ericb2 (gdb) info b
 +
 +
[18:51] ericb2 Num Type          Disp Enb Address    What
 +
 +
[18:51] ericb2 1  breakpoint    keep y  0x0338e1ea in -[MainController remoteButton:pressedDown:clickCount:] at
 +
RemoteMainController.m:118
 +
 +
[18:52] ericb2 The line is inside a method, I'll hit every time I'll be in presentation mode, and when I'll hit a key
 +
 +
[18:53] ericb2 start the presentation, and when I type a key, I see:
 +
 +
[18:53] ericb2 Breakpoint 1, -[MainController remoteButton:pressedDown:clickCount:] (self=0x3433bf0, _cmd=0x338f994,
 +
buttonIdentifier=kRemoteButtonPlay, pressedDown=1 '\001', clickCount=1) at RemoteMainController.m:118
 +
 +
[18:53] ericb2 118            pressed = @"(pressed)";
 +
 +
[18:54] ericb2 and the presentation is stopped
 +
 +
[18:54] ericb2 to continue, I have several choices :
 +
 +
[18:54] ericb2 n -> next instruction
 +
 +
[18:54] ericb2 s -> next group of instruction
 +
 +
[18:54] ericb2 c -> continue
 +
 +
[18:54] ericb2 l does list the matching code
 +
 +
[18:55] ericb2 For instance :
 +
 +
[18:55] ericb2 (gdb) l
 +
 +
[18:55] ericb2 113    #ifdef DEBUG
 +
 +
[18:55] ericb2 114        NSString* buttonName = nil;
 +
 +
[18:55] ericb2 115    #endif
 +
 +
[18:55] ericb2 116        if (pressedDown)
 +
 +
[18:55] ericb2 117        {
 +
 +
[18:55] ericb2 118            pressed = @"(pressed)";
 +
 +
[18:55] ericb2 119
 +
 +
[18:55] ericb2 120    #ifdef DEBUG
 +
 +
[18:55] ericb2 121            switch(buttonIdentifier)
 +
 +
[18:55] ericb2 122            {
 +
 +
[18:55] ericb2 Current language:  auto; currently objective-c
 +
 +
[18:55] ericb2 (gdb)
 +
 +
[18:55] ericb2 I can go up or continue
 +
 +
[18:55] ericb2 and if I need info, I can check for the stack of frames
 +
 +
[18:56] ericb2 (gdb) bt
 +
 +
[18:56] ericb2 -> will return the frames, in *reverse* order. Means, the #0 is the last one, and #1 the one before .. and so on
 +
[
 +
18:56] IZBot no issue with number 1
 +
 +
[18:56] ericb2 ooops :-)
 +
 +
[18:57] ericb2 Lets choose "n" for next
 +
 +
[18:57] ericb2 The result is :
 +
 +
[18:57] ericb2 (gdb) n
 +
 +
 +
[18:57] ericb2 121            switch(buttonIdentifier)
 +
 +
[18:57] ericb2 IMPORTANT: the current line is NOT executed yet
 +
 +
[18:57] ericb2 e.g. if you have  a= 10;
 +
 +
[18:57] ericb2 p a
 +
 +
[18:57] ericb2 can return whatevert
 +
 +
[18:58] ericb2 *only* n will validate the line. This is the context
 +
 +
[18:58] ericb2 execution context
 +
 +
[18:58] ericb2 n will continue ..
 +
 +
[18:58] ericb2 (gdb) n
 +
 +
 +
[18:58] ericb2 126                case kRemoteButtonPlay:        buttonName = @"Play";                  break;  // MEDIA_COMMAND_PLAY
 +
 +
[18:59] ericb2 and of course, we can check for the variable :
 +
 +
[18:59] ericb2 (gdb) p buttonIdentifier
 +
 +
[18:59] ericb2 $1 = kRemoteButtonPlay
 +
 +
[18:59] ericb2 so, it means the  slideshow will start ...
 +
 +
[19:00] ericb2 Next instruction :
 +
 +
[19:00] ericb2 (gdb) n
 +
 +
[19:00] ericb2 140            [ self postTheEvent:buttonIdentifier modifierFlags: 0 ];
 +
 +
[19:00] ericb2 -> means the remote sent a "Play" and I'll inform the vcl there is an event, containing the "Play" information. vcl will forward
 +
to Impress, and the slideshow will start

 +
'''EXTRA INSTALLATION'''
 +
 
 +
Use as much as possible system libs:
 +
 
 +
 
 +
libxml : --with-system-openssl
 +
 
 +
To avoid broken dependencies, libxml2 + matching libxslt (development archives) must be installed.
 +
 
 +
sudo apt-get install libxslt1-dev  libxslt1.1
 +
 
 +
Finaly,use the foloowing option to successfully pass configure : --with-system-libxml
 +
 
 +
 
 +
openssl : --with-system-openssl
 +
 
 +
 
 +
checking for openssl ... Package openssl was not found in the pkg-config search path. Perhaps you should add the directory containing `openssl.pc' to the PKG_CONFIG_PATH environment variable No package 'openssl' found
 +
 
 +
Solution:
 +
 
 +
sudo apt-get install libssl-dev
 +
 
 +
expat :  --with-system-expat
 +
 
 +
berkeleydb : --with-system-db
 +
 
 +
checking for db.h... no
 +
checking for db4/db.h... no
 +
configure: error: no. install the db4 libraries
 +
 
 +
Solution : sudo apt-get install libdb4.4-dev
 +
 
 +
icu: --with-system-icu
 +
 
 +
checking for genbrk... no
 +
configure: error: \genbrk\ not found in $PATH, install the icu development tool \genbrk""
 +
 
 +
Solution : sudo apt-get install libicu36-dev
 +
 
 +
neon : --with-system-neon
 +
 
 +
checking which neon to use... external
 +
checking for neon >= 0.24.0... configure: error: you need neon >= 0.24.x for system-neon
 +
 
 +
Solution:
 +
sudo apt-get install libneon26-dev
 +
 
 +
-----------------------------------------------------
 +
 
 +
 
 +
Install ccache :
 +
 
 +
sudo apt-get install ccache
 +
 
 +
edit the ~/.bashrc and add the lines :
 +
 
 +
CC="ccache gcc"
 +
CXX="ccache g++"
 +
export CC CXX
 +
 
 +
save, close and open a new term => ccache will be detected at the next configure
 +
 
 +
-----------------------------------------------------
 +
 
 +
Final configure command line ( experimental, might be modified) :
 +
 
 +
<pre>
 +
./configure \
 +
        --with-jdk-home=/usr/local/jdk1.5.0_17 \
 +
        --disable-build-mozilla \
 +
        --disable-gnome-vfs \
 +
        --with-ant-home=/usr/local/apache-ant-1.7.1 \
 +
        --with-lang=fr \
 +
        --with-system-libxml \
 +
        --with-system-libxslt \
 +
        --with-system-openssl \
 +
        --with-system-expat \
 +
        --with-system-db \
 +
        --with-system-icu \
 +
        --with-system-neon
 +
</pre>
 +
 
 +
And configure is successfull :-)
 +
 
 +
Bootstrap :
 +
 
 +
cd $ROOT_SOURCES
 +
 
 +
./bootstrap # builds dmake
 +
 
 +
either :
 +
 
 +
dmake
 +
 
 +
or :
 +
 
 +
cd instsetoo_native
 +
 
 +
build --all -P4
 +
 
 +
Starts the build
 +
 
 +
See you tomorrow :)
 +
 
 +
===== Missing modules =====
 +
 
 +
e.g. missing alias in DEV300_m13 :  hyphen module is not checked, causing missing headers, never delivered and then, a breakage in lingucomponent because of undefined functions/methods and so on
 +
 
 +
Solution:  check out hyphen
 +
 
 +
export CVSROOT=":pserver:anoncvs@anoncvs.services.openoffice.org:/cvs"
 +
 
 +
Note: there is another solution for experimented devs, using tunnel

Draft

Since we use subversion, some parts are obsolete, and need to be updated

Objective : create exercices, to practice OpenOffice.org tools used for development

TODO : define a list of items

Join the Project

Login and accounts

Find a page or a document

  • Find the web page for your own locale in OpenOffice.org project ( e.g. nl.openoffice.org )
  • Find the OpenOffice.org Coding Guidelines on the Wiki ( and read it ... )
  • Find the page about cws ( Child Workspace )
  • Find dev@gsl.openoffice.org mailing list archive
  • Subscribe to dev@education.openoffice.org mailing list if you didn't yet
  • Extract mails 10 to 14 from any mailing list


Bonsai use

  • Discover Bonsai
  • Visualize changes in a cws

1) Go to http://bonsai.go-oo.org/cvsqueryform.cgi

We'll try to do a request :)

2) Don't modify Module (must be All files in the repository ) Remark : note the name "repository "

3) In the Field "Branch" replace HEAD with cws_dev300_aquavcl07

4) in the field "Date" check "Since the beginning of time "

5) do not modify the other fields

6) Click "Run Query"

=> all the changes in the code, based on DEV300_m9 ( we'll explain later) are on the page !!

7) To see the diff for any commit, click in the Rev. columns. Back to retrieve the current page.

Strongly advised : 8) Look carefully at other changes, what information you can obtain here.

Remark: Bonsai helps when you are searching for changes in the code, author date .. precise information about CODE

SVN use

Ericb 16:53, 17 February 2009 (UTC)

Outline of the ClassRoom

1) Create patches using svn

2) apply a patch

3) rebuild a module

4) rebuild a module including symbols

5) run OOo with gdb (introduction of gdb use)


Introduction : in this part, we will create, apply patches using svn tool. To simplify, we'll suppose the patches are in unified mode. Means:

- 3 lines of context before the change

- a line who starts with " - " means the line before the old version (if the old version was existing)

- a line starting with " + " means after the change(s), if a new version does exist

- 3 lines of context after the change


For example :

ordinateur-de-eric-b-2:~/Desktop/ecntablet01 ericb$ svn diff sd/source/ui/slideshow/slideshow.hrc

Create patches using svn

Lot of possibilities. Below some of them. Probably better solutions do exist. This is just a little inventory of the possibilities.

  • you got a tree, did some modifications, and you want to send the patch to a friend

=> The idea is to compare your current tree with the one *before* the changes.


To visualize the changes : ordinateur-de-eric-b-2:~/Desktop/moz2seamonkey01 ericb$ svn diff slideshow/source/inc/userpainteventhandler.hxx

The command (without the prompt) is :

svn diff slideshow/source/inc/userpainteventhandler.hxx

The result is : 

Index: slideshow/source/inc/userpainteventhandler.hxx
===================================================================

To create the patch for true, the command is : svn diff slideshow/source/inc/userpainteventhandler.hxx > my pretty patch.diff

And " my_pretty_patch.diff " will contain the same.


  • you want to create a patch between a cws and a milestone (the one the cws is based on )

For example, to extract the changes in helpcontent2, ab65 introduced

svn diff http://svn.services.openoffice.org/ooo/tags/DEV300_m35/helpcontent2 http://svn.services.openoffice.org/ooo/cws/ab65/helpcontent2 > mydiff.diff


  • you want to create a patch between two svn revisions for a given cws


IMPORTANT: you can follow the recent commits there : http://cia.vc/stats/project/OOo

Example of change (in one line) :

svn diff http://svn.services.openoffice.org/ooo/cws/ooo31gsl2/vcl@268180 http://svn.services.openoffice.org/ooo/cws/ooo31gsl2/vcl@268182


  • using svn log, you want to create the diff between two revisions of the same file

For example :

ordinateur-de-eric-b-2:~/Desktop/moz2seamonkey01 ericb$ svn log configure.in Enter passphrase for key '/Users/ericb/.ssh/id_dsa_ooo_svn':

r267684 | ericb | 2009-02-12 18:13:52 +0100 (Thu, 12 Feb 2009) | 1 line

  1. i94628# fix a path issue for finding seamonkey01

r267656 | ericb | 2009-02-12 14:13:21 +0100 (Thu, 12 Feb 2009) | 1 line

  1. i94628# other missing changes for Windows

Apply a patch

Essential options :

--dry-run : fakes the patch application *extremely usefull* if you want to check whether a patch will apply, without create garbage in your tree

-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

-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* you apply it form the right location

-p1 : you remove the first subdir of the path for every to be patched file listed in th patch


Correct way of application :

Fake the application :

patch --dry-run -p0 < my_patch.diff

If nothing wrong occurs :

patch -p0 < my_patch.diff


Other possibility, not recommended because of the UUOC (useless use of cat) :

cat my_patch.diff | patch -p0


Depth of the application:

e.g. let's suppose a patch has to modify  :

vcl/source/aqua/source/window/salframeview.mm vcl/source/aqua/source/gdi/salprn.cxx vcl/source/aqua/inc/salframeview.h


You can :

apply the patch from

  • the root of the sources :

patch -p0 < my_patch.diff

  • inside vcl :

patch -p1 < my_patch.diff

  • inside vcl/aqua

patch -p2 < my_patch.diff


You cannot apply patch from elsewhere, because the paths will no longer match with the one every of the file contained in it.


  • mix of applying patches + svn use

e.g. you did a wrong change in a module, and you want to reverse it directly :

cd module

svn diff apath/afile.cxx | patch -R -p0

for the entire local tree :

svn diff . | patch -R -p0


Rebuild a module where a patch has been applied

  • Introduction

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.

- the first prj/build.lst does contain the modules dependencies, means all the listed modules are prerequisites - everything built inside a module is put in type_os_proc.pro

e.g. on Mac OS X, type == unx , os == macx , I for Intel -> output dir is unxmacxi.pro

Note: have a look in solenv/inc -> all the possible arch/os have their own makefile, containing the essential for the build.


The last modification date is used to check the dependencies.

Rule : If a .o is older than it's depenencies, it is rebuild -> once you modified a file ( touch file is enough) , build in a module will create a new lib

  • rebuild libvclmxi.dylib on Mac ( .so on Linux, .dll on Windows )

Hypothesis : we suppose the build is completed, and successfull.

cd vcl touch aqua/source/gdi/sallayout.cxx build

If you are in aqua/source/gdi , and you want to rebuild *only* the files listed in the makefile in the current dir, do :

dmake killobj build

Once done, and if you want to see the changes packaged, :

deliver cd ../instsetoo_native build # will rebuild a new installset

Else, if you just want to test your lib, put it in the right subdir (probably in <Install_dir>/OpenOffice.org.app/Contents/basis-link/program on Mac OS X )


Build including symbols

Example

-> in vcl

cd vcl mv unxmacxi.pro unxmacxi.pro_back # keep the normal build build debug="a_non_empty_sting" # means " build debug=t " is ok

The final lib, including symbols for debugging, will be in unxmacxi.pro/lib (on Mac OS X )

Replace the one already in <Install_dir>/OpenOffice.org.app/Contents/basis-link/program on Mac OS X

To debug using gdb,do :

cd <Install_dir>/OpenOffice.org.app/Contents/program

gdb --args soffice apath/afile

"r" (to start) .. and so on;

Happy debugging !

gdb basics

FIXME : make the look of the log more .. appealing ;)

Candidates ?

TODO : add my document providing the most usefull gdb commands

Outline of the ClassRoom

  • Prerequisites for the test
  • Reminder about what happens when building in a module
  • Add symbols in a library
  • Introduction of gdb use
  • Launch OOo using gdb
  • Play with it (discovery)


[18:05] ericb2 So today, we'll start playing with gdb + Ooo

[18:05] ericb2 who does have a full OOo build at hand ?

[18:06] ericb2 ok :)

[18:06] ericb2 As pre-requisites , I'll suppose :

[18:06] ericb2 - there is a complete build working already

[18:06] ericb2 - there is a working installset , and we will launch it using the terminal [18:06] ericb2 Thus, if you want to redo at home, or later, you just have to read and try

[18:07] ericb2 Reminder : what happens when something is built

[18:07] ericb2 we'll use <module> for whatever subdir of the OOo tree, aka "module" most of the time

[18:08] ericb2 <module>/prj/build.lst does contain the list of the subdirs containing a makefile

[18:08] ericb2 Means: Every product is built in the output dir. e.g. : unxmacxi.pro on Mac Intel

[18:08] ericb2 we have the same tree inside all the modules:

[18:08] ericb2 unxmacxi.pro/bin

[18:09] ericb2 unxmacxi.pro/lib

[18:09] ericb2 unxmacxi.pro/inc

[18:09] ericb2 ... and so on (look yourself )

[18:09] ericb2 to rebuild a module, just remove this directory

[18:09] ericb2 Once all the .o are build, the libs, and/or the binaries / resources / whatever are "delivered" from the unxmacxi.pro dir to the solver

[18:11] ericb2 The information providing the list of what has to be delivered is always in : <module>/prj/d.lst

[18:12] ericb2 these files are text files, using a "Windows" separator, but this is not a problem at all

[18:12] * l_zahir (n=chatzill@142.204.16.10) has joined #education.openoffice.org

[18:13] ericb2 If we summarize : a normal build provides binaries like libraries, who are stripped when the are delivered. Between the unxmacxi.pro and their place in the "solver "

[18:14] ericb2 Important: to be able to trace using gdb, we'll need to add symbols, lines of code and a lot of information inside the binaries

[18:14] ericb2 Howto add symbols in a library ?

[18:14] ericb2 1) first approach

[18:15] ericb2 -> look at configure extra option : --disable-strip-solver

[18:15] ericb2 To verify by yourself, just place you at the root of the sources (since DEV300_m40, there is no longer config_office subdir)

[18:15] ericb2 and do : ./configure --help | grep -4 solver

[18:16] ericb2 you'll have several lines explaining the right option

[18:16] ericb2 Tip : if you're familiar with configure, better read configure itself, more informative ;-)

[18:17] ericb2 and if you know a bit of autoconf, you can even hack configure.in, and run autoconf to regenerate a new configure :)


[18:18] ericb2 The first approach has a drawback : just a bit of information is inside the binary, and that's not enough most of the time,

when you have a complex problem to solve


[18:19] ericb2 2) second approach

[18:19] ericb2 consider only a part of the code, for tracing

[18:20] ericb2 The method is equivalent to use --enable-debug at configure time, but nobody uses this option. the reason is simple : all libraries become huges, and OOo won't probably launch correctly.

[18:21] ericb2 e.g. : the libsw (writer) becomes 660MB heavy

[18:22] fardad ericb2: when you say correctly, does it mean it will be too slow, or it will not function properly?

[18:22] Kamots wow, that's a lot of extra weight

[18:23] ericb2 fardad: yes, imagine 10 libs of 500MB every + some other 100MB and so on

[18:23] ericb2 Kamots: I'll explain you how to proceed

[18:23] fardad wow, :o

[18:24] ericb2 Other important information

[18:24] ericb2 about assertions

[18:24] ericb2 There is another option in configure

[18:24] ericb2 --enable-dbgutil

[18:25] ericb2 Include additional debugging utilities, such assertions, object counting, etc. Larger build.

[18:25] ericb2 Independent from --enable-debug

[18:25] ericb2 the *second one* does concern assertions in the code :

[18:25] ericb2 DBG_ASSERT( !(rALR.flags & kATSGlyphInfoTerminatorGlyph),

[18:25] ericb2 "ATSLayout::InitGIA(): terminator glyph not marked as deleted!" );

[18:26] ericb2 -> if the condition is not verified -> boom .. and a window will appear, containing the message

[18:26] ericb2 if --enable-dbgutil is not in the configure command line, assertions are not included

[18:27] ericb2 As you understood, assertions are for development, not for end users ;-)

[18:27] ericb2 So, we use to add symbols for debugging for some libs, in a given module only

[18:27] ericb2 Counterpart : needs to rebuild the module

[18:28] ericb2 The process is very simple :

[18:28] ericb2 cd <module>

[18:28] ericb2 mv unxmacxi.pro unxmacxi.pro_backup

[18:28] ericb2 build debug=t

[18:28] ericb2 Do *always* a backup of your build, because the binaries in the output tree, do match with stamps in the solver

[18:29] ericb2 if you modify something, you'll have to redo a build, and a "deliver". Elser, the build can break at postprocess, or at then end, because the stamp between the solver and the module do not match

[18:29] ericb2 that's just harmless, but if you are not aware, you can lose a while before someone explains you what happens

[18:31] ericb2 As example, I'll rebuild a little lib , to show you the difference

[18:31] ericb2 cd apple_remote/

[18:32] ericb2 source ../MacOSXX86Env.Set.sh

[18:32] ericb2 sorry, I forgot :-)

[18:32] ericb2 mv unxmacxi.pro unxmacxi.pro_back

[18:32] ericb2 build debug=t

[18:32] ericb2 Important: whatever you put, will work

[18:33] ericb2 t is one letter, but once the string is not empty, debug is true

[18:33] ericb2 means all the code included between #ifdef DEBUG ... #endif or some other macros, will be included

[18:34] ericb2 e.g. :

[18:34] ericb2 #ifdef DEBUG

[18:34] ericb2 // debug purpose

[18:34] ericb2 NSLog(@"reset... (after listening to remote)");

[18:34] ericb2 #endif

[18:34] ericb2 -> in the terminal, I'll see the information

[18:34] ericb2 NSLog is sort of cout

[18:35] fardad ic,

[18:35] ericb2 After the rebuild :

[18:35] ericb2 ls -l unxmacxi.pro/lib/libAppleRemotemxi.dylib

[18:35] * lgodard has quit ("Leaving.")

[18:35] ericb2 -rwxr-xr-x 1 ericb ericb 159932 Feb 19 18:31 unxmacxi.pro/lib/libAppleRemotemxi.dylib

[18:35] ericb2 ls -l unxmacxi.pro_back/lib/libAppleRemotemxi.dylib

[18:36] ericb2 -rwxr-xr-x 1 ericb ericb 52436 Feb 12 14:31 unxmacxi.pro_back/lib/libAppleRemotemxi.dylib

[18:37] ericb2 the first one does contain strings and a lot of other stuff

[18:37] ericb2 Now .. Launch OOo in a terminal :)

[18:37] ericb2 before, we'll copy the lib in the bundle

[18:37] IZBot News from cws: native227: created

[18:38] ericb2 For the rest, my bundle is in the Desktop/test_eraser folder (I'm on Mac OS X )

[18:38] ericb2 Means, the Bundle is the dir : ~/Desktop/test_eraser/OpenOffice.org.app

[18:38] ericb2 So, I'll open a terminal, and I'll do :

[18:39] ericb2 cd ~/Desktop/test_eraser/OpenOffice.org.app/Contents/program

[18:39] ericb2 the idea, is to start gdb form the directory containing soffice (the binary )

[18:39] ericb2 and the command line is :

[18:40] ericb2 gdb --args ~/Desktop/est.odp

[18:40] ericb2 you'll see gdb tell you a lot of things. If you don't want to see that the next time, you can add -q (for quiet) option

[18:41] ericb2 as you can see nothing happens :)

[18:41] ericb2 the reason is: the binary is not "running"

[18:42] ericb2 oops, sorry

[18:42] ericb2 gdb --args soffice ~/Desktop/est.odp

[18:42] ericb2 is the right command line

[18:42] ericb2 to redo; just enter "q"

[18:42] ericb2 and type the correct command

[18:43] ericb2 now, type r ( shortcut for "run" )

[18:43] ericb2 -> OOo will start

[18:43] ericb2 and open the file

[18:44] ericb2 in the terminal, you no longer have the control. To stop the execution, do "CTRL-C"

[18:44] ericb2 Program received signal SIGINT, Interrupt.


[18:44] ericb2 0x90009cd7 in mach_msg_trap ()

[18:44] ericb2 (gdb)

[18:44] ericb2 OOo is stopped

[18:44] ericb2 you can enter whatever command, like " info frame "

[18:45] ericb2 to continue, type : c

[18:45] ericb2 The result is : (gdb) c

[18:45] ericb2 Continuing.

[18:45] ericb2 and OOo is no longer stopped

[18:45] ericb2 Add a breakpoint

[18:45] fardad amazing...

[18:46] ericb2 fardad: I know this is difficult like that, but people will redo later, and ask whenever they want

[18:46] ericb2 on the channel

[18:46] ericb2 we'll explain them

[18:46] fardad I understand

[18:47] ericb2 Let's add a breakpoint now

[18:47] ericb2 to know whether breakpoints are set or not, the command is :

[18:47] ericb2 info b

[18:47] ericb2 (means info breakpoints)

[18:48] ericb2 exactly :

[18:48] ericb2 CTRL-C

[18:48] ericb2 info b

[18:48] ericb2 The result is :

[18:48] ericb2 (gdb) info b

[18:48] ericb2 No breakpoints or watchpoints.

[18:48] ericb2 of course

[18:48] ericb2 so let's set one

[18:49] ericb2 Since only libAppleRemotemxi.dylib has symbols, I'll have to set one in whatever file included

[18:49] ericb2 say RemoteMainController.m

[18:49] ericb2 We can either choose a method

[18:50] ericb2 Syntax : b 'class:myMethod'

[18:50] ericb2 or at some line :

[18:50] ericb2 Syntax : b RemoteMainController.m:118

[18:50] ericb2 The result is :

[18:50] ericb2 (gdb) b RemoteMainController.m:118

[18:50] ericb2 Breakpoint 1 at 0x338e1ea: file RemoteMainController.m, line 118.

[18:51] ericb2 and using the up/down arrow, the history is available (no need to type several times the same command ;)

[18:51] ericb2 (gdb) info b

[18:51] ericb2 Num Type Disp Enb Address What

[18:51] ericb2 1 breakpoint keep y 0x0338e1ea in -[MainController remoteButton:pressedDown:clickCount:] at RemoteMainController.m:118

[18:52] ericb2 The line is inside a method, I'll hit every time I'll be in presentation mode, and when I'll hit a key

[18:53] ericb2 start the presentation, and when I type a key, I see:

[18:53] ericb2 Breakpoint 1, -[MainController remoteButton:pressedDown:clickCount:] (self=0x3433bf0, _cmd=0x338f994, buttonIdentifier=kRemoteButtonPlay, pressedDown=1 '\001', clickCount=1) at RemoteMainController.m:118

[18:53] ericb2 118 pressed = @"(pressed)";

[18:54] ericb2 and the presentation is stopped

[18:54] ericb2 to continue, I have several choices :

[18:54] ericb2 n -> next instruction

[18:54] ericb2 s -> next group of instruction

[18:54] ericb2 c -> continue

[18:54] ericb2 l does list the matching code

[18:55] ericb2 For instance :

[18:55] ericb2 (gdb) l

[18:55] ericb2 113 #ifdef DEBUG

[18:55] ericb2 114 NSString* buttonName = nil;

[18:55] ericb2 115 #endif

[18:55] ericb2 116 if (pressedDown)

[18:55] ericb2 117 {

[18:55] ericb2 118 pressed = @"(pressed)";

[18:55] ericb2 119

[18:55] ericb2 120 #ifdef DEBUG

[18:55] ericb2 121 switch(buttonIdentifier)

[18:55] ericb2 122 {

[18:55] ericb2 Current language: auto; currently objective-c

[18:55] ericb2 (gdb)

[18:55] ericb2 I can go up or continue

[18:55] ericb2 and if I need info, I can check for the stack of frames

[18:56] ericb2 (gdb) bt

[18:56] ericb2 -> will return the frames, in *reverse* order. Means, the #0 is the last one, and #1 the one before .. and so on [ 18:56] IZBot no issue with number 1

[18:56] ericb2 ooops :-)

[18:57] ericb2 Lets choose "n" for next

[18:57] ericb2 The result is :

[18:57] ericb2 (gdb) n


[18:57] ericb2 121 switch(buttonIdentifier)

[18:57] ericb2 IMPORTANT: the current line is NOT executed yet

[18:57] ericb2 e.g. if you have a= 10;

[18:57] ericb2 p a

[18:57] ericb2 can return whatevert

[18:58] ericb2 *only* n will validate the line. This is the context

[18:58] ericb2 execution context

[18:58] ericb2 n will continue ..

[18:58] ericb2 (gdb) n


[18:58] ericb2 126 case kRemoteButtonPlay: buttonName = @"Play"; break; // MEDIA_COMMAND_PLAY

[18:59] ericb2 and of course, we can check for the variable :

[18:59] ericb2 (gdb) p buttonIdentifier

[18:59] ericb2 $1 = kRemoteButtonPlay

[18:59] ericb2 so, it means the slideshow will start ...

[19:00] ericb2 Next instruction :

[19:00] ericb2 (gdb) n

[19:00] ericb2 140 [ self postTheEvent:buttonIdentifier modifierFlags: 0 ];

[19:00] ericb2 -> means the remote sent a "Play" and I'll inform the vcl there is an event, containing the "Play" information. vcl will forward to Impress, and the slideshow will start

[19:02] ericb2 This is only the introduction (if people are intersted, we can do another workshop about gdb another day )

[19:02] ericb2 To quit *cleanly*

[19:02] ericb2 delete the brekapoints :

[19:02] ericb2 c

[19:02] ericb2 to continue


[19:02] ericb2 and then Quit OOo using CMD Q

[19:03] ericb2 The result is :

[19:03] ericb2 Program exited normally.

[19:03] ericb2 (gdb)

[19:03] ericb2 Then quit gdb :

[19:04] BartB not at the moment, might have some later

[19:05] ericb2 I forgot, to affect a value, the command is "set"

[19:05] ericb2 e.g. :

[19:05] MrBraini ericb2: last lecture you stated the notes from the lectures will be placed on the wiki? where can we find the notes in the wiki?

[19:05] ericb2 (gdb) : set a=10

[19:05] daeseon_ not now may be later.

[19:05] ericb2 MrBraini: I'll put them on the wiki, yes

[19:05] l_zahir is there a y way so we can see multiple line before their execution?

[19:05] l_zahir lgodard

[19:05] ericb2 l_zahir: list ?

[19:05] ericb2 l_zahir: l is the shortcut

[19:06] ericb2 l_zahir: I forgot, there is another way to break, using conditional breakpoint


[19:06] l_zahir oksu during debugging or before?

[19:06] ericb2 l_zahir : you can go up and down in the frames

[19:06] l_zahir lgodard

[19:06] ericb2 l_zahir to retrieve a context

[19:06] l_zahir ok , thanks

[19:07] ericb2 l_zahir: I think, the best is to redo a workshop, with everything ready

[19:07] ericb2 l_zahir: but nothing will replace the experiences [ 19:07] l_zahir sure

[19:08] <ericb2> l_zahir: no problem.

[19:08] <ericb2> BTW, I provided a patch for rhino and scripting

[19:08] <l_zahir> Oh, good :)

[19:08] <ericb2> was my fault: two modules where concerned, and this is what caused some issues

[19:08] <ericb2> l_zahir: one minute, I'll retrive the URL

[19:09] <l_zahir> thanks

[19:09] <l_zahir> :)

[19:09] <ericb2> http://eric.bachard.free.fr/mac/aquavcl/patches/aqua_February2009/17th_february/complete_rhino_and_scripting_patch.diff

[19:09] <ericb2> l_zahir: this patch should apply cleanly on m40

[19:09] <ericb2> l_zahir: not sure it will work, I'm not a Java specialist ;)

[19:10] <ericb2> ok, I'll have to stop.

[19:10] <l_zahir> I'll try

[19:10] <ericb2> If you have further questions, ask directly, and if I see them, I'll answer

LXR use

[Complete me]

Checkout the code

Preliminary:

- we suppose you have some bash knowledge, and some programming skills

- your .cvsrc file is ok (else ask on #education.openoffice.org )

Now, open a terminal, use bash, and do :

0 ) create the environment


If you don't have a proxy, do , (in a terminal) :

export CVSROOT=":pserver:anoncvs@anoncvs.services.openoffice.org:/cvs"


There is a proxy, and nothing works using the line above, do, (in a terminal) :

Let the proxy be 100.101.102.103 ( name proxy.machine.education.org ) , and the open port 1234, then just do :

export CVSROOT=":pserver;proxy=100.101.102.103;proxyport=1234:anoncvs@anoncvs.services.openoffice.org:/cvs"


And if you ignore the IP address of the gateway, but you know its name, do, (in a terminal) :

export CVSROOT=":pserver;proxy=proxy.machine.education.org;proxyport=1234:anoncvs@anoncvs.services.openoffice.org:/cvs"


IMPORTANT : proxy.machine.education.org is just a fake name, as example. Please replace it with the one in your network :)


... it should work now (else, contact your sys admin).

For the next step, create TMP dir (command: mkdir TMP )

cd TMP

1) checkout vcl module from DEV300_m31

cvs co -r DEV300_m31 dtrans

Question: what happens ?


Download all OpenOffice.org tree :

mkdir DEV300_m31

cd DEV300_m31

cvs -4 co -r DEV300_m31 OpenOffice2

( -z4 is optional )

-> once done ( can be very long), and if no error occurs, you got all OpenOffice.org source code from DEV300_m31 Milestone !!

Create a patch

2) Modify one file, do "cvs up" , and comment on the result

3) using grep , retrieve the name of the milestone in the sources

4) checkout vcl from a cws under development

cvs -z4 co -r cws_dev300_aquavcl07 vcl

5) retrieve the cwsname in the sources

6) analyse the list of the subdirectories vcl contains

7) modify the code in vcl/source/gdi/sallayout.cxx

(write whatever you want, respecting C++ syntax prefered ;)

8) create a diff with the OpenOffice.org repository

change directory outside of vcl

in the current dir ( TMP ) , do :

cvs diff -u vcl > my_pretty_patch.diff

9) What does contain the patch ?

Apply and Reverse a patch

  • Simulate a patch application
  • Apply it for true


10) How reverse your changes ?

11) Be sure you have enough place on your hard disk ( count 2GB )

Fix a build breaker (most common breakages )

use : --with-ant-home=/usr/local/apache-ant-1.7.1

EXTRA INSTALLATION

Use as much as possible system libs:


libxml : --with-system-openssl

To avoid broken dependencies, libxml2 + matching libxslt (development archives) must be installed.

sudo apt-get install libxslt1-dev libxslt1.1

Finaly,use the foloowing option to successfully pass configure : --with-system-libxml


openssl : --with-system-openssl


checking for openssl ... Package openssl was not found in the pkg-config search path. Perhaps you should add the directory containing `openssl.pc' to the PKG_CONFIG_PATH environment variable No package 'openssl' found

Solution : sudo apt-get install libicu36-dev

neon : --with-system-neon

checking which neon to use... external checking for neon >= 0.24.0... configure: error: you need neon >= 0.24.x for system-neon

Solution: sudo apt-get install libneon26-dev


Install ccache :

sudo apt-get install ccache

edit the ~/.bashrc and add the lines :

CC="ccache gcc" CXX="ccache g++" export CC CXX

save, close and open a new term => ccache will be detected at the next configure

Final configure command line ( experimental, might be modified) : 

./configure \
        --with-jdk-home=/usr/local/jdk1.5.0_17 \
        --disable-build-mozilla \
        --disable-gnome-vfs \

Missing modules

e.g. missing alias in DEV300_m13 : hyphen module is not checked, causing missing headers, never delivered and then, a breakage in lingucomponent because of undefined functions/methods and so on

Solution: check out hyphen

export CVSROOT=":pserver:anoncvs@anoncvs.services.openoffice.org:/cvs"

Note: there is another solution for experimented devs, using tunnel

cvs co -r DEV300_m13 hyphen
