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.

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
Index: sd/source/ui/slideshow/slideshow.hrc =================================================================== --- sd/source/ui/slideshow/slideshow.hrc (revision 267130) +++ sd/source/ui/slideshow/slideshow.hrc (working copy) @@ -38,8 +38,10 @@ #define CM_SCREEN_BLACK 5 #define CM_SCREEN_WHITE 6 #define CM_ENDSHOW 7 -#define CM_FIRST_SLIDE 8 -#define CM_LAST_SLIDE 9 -#define CM_SLIDES 10 +#define CM_ERASE_ALLINK 8 +#define CM_ERASE_INK 9 +#define CM_FIRST_SLIDE 10 +#define CM_LAST_SLIDE 11 +#define CM_SLIDES 12 #endif
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 =================================================================== --- slideshow/source/inc/userpainteventhandler.hxx (revision 267652) +++ slideshow/source/inc/userpainteventhandler.hxx (working copy) @@ -53,6 +53,9 @@ virtual ~UserPaintEventHandler() {} virtual bool colorChanged( RGBColor const& rUserColor ) = 0; + + virtual bool eraseAllInkChanged(bool const& rEraseAllInk) =0; + virtual bool eraseInkChanged(bool const& rEraseInk) =0; virtual bool disable() = 0; };
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
- i94628# fix a path issue for finding seamonkey01
r267656 | ericb | 2009-02-12 14:13:21 +0100 (Thu, 12 Feb 2009) | 1 line
- 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

[19:05] 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
[19:10] * Remaille (n=remi@abo-166-155-68.bdx.modulonet.fr) has joined #education.openoffice.org
[19:10] * ChanServ gives channel operator status to Remaille
[19:11] <l_zahir> sure
[19:11] <ericb2> Other questions ?
[19:12] <ericb2> If you have no other questions, I'll stop for a while, but in ~2 hours max, I'll be back.
[19:12] <ericb2> The content of the classroom will be on the wiki
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
export CVSROOT=":pserver:anoncvs@anoncvs.services.openoffice.org:/cvs"
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"
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 )
A) Building OpenOffice.org
Note: add your own experience here !
Building on Ubunutu 7.10
Ubuntu version : 7.10 - Gutsy Gibbon
Estimated time for the cnofiguration: 1h30
1) Download OpenOffice.org source code
install subversion : sudo apt-get install subversion
Command line for the download : svn checkout svn://svn.services.openoffice.org/ooo/tags/DEV300_m39
2) Java

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 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 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 \ --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
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
cvs co -r DEV300_m13 hyphen
