[dev] Question on accessing hyphenation dictionaries and related metadata

[Dr.Leo]

Hello,

I am the author of PyHyphen, a hyphenation package for the Python 
programming language (http://pypi.python.org/pypi/PyHyphen/).

PyHyphen is essentially a wrapper around 'libhyphen', the
C library that oo uses for hyphenation.

PyHyphen contains some handy tools to download hyphenation dictionaries 
and related metadata from the deprecated lingual components site for OO 
2.x. See the metadata file at 
http://ftp.osuosl.org/pub/openoffice/contrib/dictionaries/hyphavail.lst


I would like to upgrade PyHyphen to use the new extensions format 
introduced with OO 3.x.But I haven't found any docs explaining where to 
find the equivalent of
hyphavail.lst. somewhere on the site there should be an xml file listing 
all available hyphenation dictionaries with some metadate on each. This 
meta data is needed to write code to access the new dictionaries.


Any help would be very much appreciated. As I am not subscribed to the 
list, please put fhaxbo...@googlemail.com on cc.

[dev] question of openOffice sdk

[always_rick]

Hi all, I am new here. Forgive me if the question is really silly.

I am using Java, besides *.jar file, what else do I need? Do I have to
install OpenOffice?

I guess "Abs.Vorl." is abbreviation of "Absatzvorlage", but why in

This is probably only the amount needed by code when you start the
application and open the first document. Subsequent documents use less
memory, depending on document content of course.

That is exactly what happens when we save a document. But this happens 
outside of the zip code. This is application logic and shouldn't be

I don't think, that something like this is possible with
OpenOffice.org. This might be possible with some tools that are
specific to your operating system. But as I said, ask on the other list
and I'm sure, there's someone who can point you into the right
direction.

[dev] Question for a software-solution!

Dearest Open Office

I have a question for a software-solution, that no one can answer!

Have you specialists got a software-solution for me as a _journalist_?
My sons are Open Office fans and told me, that you were the greatests!!

Here`s the problem:

_First_ I want to copy only the file-strukture from my extern 
hard-disc-drive-archive,

without the contained documents, into my laptop, so that in the laptop
I have got the empty structure of my archive-file-system.
This would be great!!

My file-system in the extern archive is very large
and the file-system has got a deep strukture of file in file in file ...,
as deep as it is possible.
There are huge amounts of documents in these files of my archive.

_The second_ (luxury-) duty would be an order, that deletes in my laptop
all content out of a specific chosen file and out of its subfiles
- without deleting the files.

This is the archive-system, that I need urgently.
I want to work with an "empty" laptop!
My laptop is just a little Acer with Windows Vista.
And I have got only Open Office.

I hope, I explained and thought about everything well enough

Hi Frank,

yes, you are right, i tried to insert a more readable (localized) display name,
but wasn't aware that oo 3.2  will use the "node name" for database access.

so for upward compatibility i will change it back to the registration name ...
otherwise our users's will have to use "Edit - Echange Database..." or
even change macro code in oo 3.x ...

thanks :-)

The code for this happen[s/ed] to be a little ... inconsistent. When the
config data is created by OOo itself, then the node name and the
property value are identical. When reading the data, the node name is
taken as registration name. Strictly, this is wrong, of course, but it's
noticed only when the node name and the prop value are not identical.

On the DEV300 code line, this has been fixed - now the property value is
taken as registration name, the node name can be an arbitrary logical
name (preferably something like "org." to ensure uniqueness).

In addition, an interface css.sdb.XDatabaseRegistrations [1] has been
introduced, which hides the configuration data from you, so there is no
need to tamper with it directly (The exception would be an extension
bringing its own configuration data with it, but even here, an on-demand
registration using XDatabaseRegistrations and the new XDeploymentHook
would be possible).

The question: how would one create and implement UNO components in
scripting languages that can be deployed via the OOo (Java-based)
scripting framework (e.g. JavaScript/Rhino, BeanShell, but also ooRexx
or other BSF-scripting languages)?

Some of the questions that may be needed to be addressed would be:

* How can one dynamically add IDL kind of type information to the
  registry, such that the new types become reflectable?
* How can one register a component dynamically ?
* How can one supply a service manager object to be used for
  instantiating instances?
* How can one take advantage of helper classes (XWeak, XComponent) ?

Are there any links/hints to postings, definitions, sketches of such a
functionality? Is there some experimental implementation available
somewhere (or is it even available already)?

Short of that, how is the Python support implemented? Is there a
documentation about the architecture and the UNO APIs it uses? What
are/were the problems there, are there any shortcomings?

---

Maybe to rephrase this question differently: I would like to come up
with a solution for OOo disptachable scripting languages, in which
script programmers have no need for the OOo SDK, if they wish to create
UNO components in their scripting language of choice. (The necessary
complexity involved in creating UNO components, should be reduced to an
absolute minimum, where this minimum should be to have no need for
installing the OOo SDK.)

TIA,

[dev] question on open office

[snoopmojo]

I have open office installed and I used to be able to choose open office as a 
selection when asked "open with" for E mail attachments, pictures, etc. This no 
longer appears as an option. Please advise how I can put in Openoffice as an 
"open with" option. Thank you.

That data is stored in the "OOo configuration" (sometimes also called 
the "OOo registry").  Although the configuration is based on XML files 
(for now, at least), you should not operate on those files directly, but 
rather use the corresponding UNO services to access the data (see the 
"Configuration Management" chapter in the OOo Developer's Guide; the 
relevant configuration data is at org.openoffice.UserProfile, I think).

Yes, this would be very desirable. Thanks for offering your help, it's
highly appreciated. Please let us know if you need any assistance.

Updating to the latest version is the suggestion given here:

[Zvi Har'El]

Hi,


Writer2latex is also responsible to the xhtml export from OOo writer.
Writer2latex has fixed many bugs, e.g, current xhtml export doesn't
generate footnotes and endnotes, and Writer2later 0.5 when doing xhtml
export handles footnotes and endnotes correclty. I have installed
Writer2latex 0.5 as an export plugin in OOo 2.3 and it satisfies all my
needs, but I am certain there should be give na high priority in
updating the default version.


Best,


Zvi.

[dev] question about writer2latex

[Brad Walker]

I'm unsure which project this question should be posted to. So I
thought I would send it here first and then you can direct me to the
more appropriate place.

I'm interested in the Export feature of the OOo Writer. Specifically
the export to LaTeX2e filter. From what I gather the current OOo
export to LaTeX feature is handled by writer2latex. I've looked
through the archives and noticed the version shipping with OOo 2.3 is
writer2latex version 0.4.

There is a much more current version 0.5 and there have been several
versions between the two. There are a lot of bug fixes in version 0.5.

So I'm interested in knowing if there is any desire to get our export
filter brought up to a more current version. If so, I might be
interested in working on it.

Thanks.

[dev] Question: How to add formatID to OpenOfficeWriter?

[Schuster Gerhard]

Hi developers,


I'm Gerhard from www.00easytracker.org.
I want to use OpenOffice as core for a new requirements engeneering
software. (You'll find a dessign scetch of the project here:
http://www.ooeasytracker.org/tikiwiki/tiki-read_article.php?articleId=7)


Therfore I would like to know how to add formatID to
OpenOffice text.
This formatID shall be the means to link information snippets.
So if the user finds a piece of information in a OpenOffice
document, he can attach an unique ID to this section and with this ID
he can link it to another piece of information within the same
or another document.


Here the detailed requirements:

1) I want to be able to select a piece of text within OpenOfficeWriter
and attach an invisible formatID to it.
2) This formatID shall not show its self in OpenOfficeWriter but be
present in the documents ODF file.
3) It shall be possible to assign different formatID's to overlapping text
sections.
4) It shall be possible to assign a formatID to a subsection of text
that has already a formatID
5) It shall be possible to search for text that has this formatID
6) The formatID shall be a alphanumeric string with white spaces
7) The new function does not show its self to the user in OpenOffice but it will
be called by the java application that embeddes the OpenOffice
document
8) I want to code in Java, if possible and I want to use the UNO bridge
9) The new feature shall be a plugin to OpenOffice and it shall not be
necessary to build a new OpenOffice every time a new version gets
released


I could use the hyperlink format as a workarround.
I would only use the Name field and leave the URL field empty.
But this solution does not fullfill requirement 4,5 and 5.
There are workarrounds for that too, which might work fine with
short documents, but probbably not with long ones.


Is there anybody arround who is able and willing to help?

Ah, I see. This was the reason why we added the SubFilter API. The
document already was initialized as an empty document. So trying to
assign another storage directly can lead to inconsistencies. For that
reason we added the new, explicit API.

So the only way I see is upgrading to at least OOF680 and using SubFilter.

No, you can't copy the document content that way.
If loadFromStorage() doesn't work you have to update and use the SubFilter.

Perhaps you tell us what loadFromStorage() does. Or you can debug the
code to see what goes on there. Maybe it's a bug in the code. But even
then you had to update as nobody will fix bugs on this ancient code line.


The source code of loadFromStorage in OOB680 :

void SAL_CALL SfxBaseModel::loadFromStorage( const REFERENCE< 
XSTORAGE>& 	xStorage,

const SEQUENCE< PROPERTYVALUE >& aMediaDescriptor )
throw ( ILLEGALARGUMENTEXCEPTION,
DOUBLEINITIALIZATIONEXCEPTION,
IOEXCEPTION,
EXCEPTION,
RUNTIMEEXCEPTION )
{
::vos::OGuard aGuard( Application::GetSolarMutex() );
if ( impl_isDisposed() )
throw DISPOSEDEXCEPTION();

if ( !m_pData->m_pObjectShell.Is() )
throw IOEXCEPTION(); // TODO:

if ( m_pData->m_pObjectShell.Is() )
{
if( m_pData->m_pObjectShell->GetMedium() )
// if a Medium is present, the document is already initialized
throw DOUBLEINITIALIZATIONEXCEPTION();

// after i36090 is fixed the pool from object shell can be used
// SfxAllItemSet aSet( m_pData->m_pObjectShell->GetPool() );
SfxAllItemSet aSet( SFX_APP()->GetPool() );

// the BaseURL is part of the ItemSet
SfxMedium* pMedium = new SfxMedium( xStorage, String() );
TransformParameters( SID_OPENDOC, aMediaDescriptor, aSet );
pMedium->GetItemSet()->Put( aSet );

// allow to use an interactionhandler (if there is one)
pMedium->UseInteractionHandler( TRUE );

// TODO/LATER: in case of template storage, the temporary copy must be 
created
	SFX_ITEMSET_ARG( &aSet, pTemplateItem, SfxBoolItem, SID_TEMPLATE, 
sal_False);

BOOL bTemplate = pTemplateItem && pTemplateItem->GetValue();
m_pData->m_pObjectShell->SetActivateEvent_Impl( bTemplate ? 
SFX_EVENT_CREATEDOC : SFX_EVENT_OPENDOC );

m_pData->m_pObjectShell->Get_Impl()->bOwnsStorage = FALSE;

// load document
if ( !m_pData->m_pObjectShell->DoLoad(pMedium) )
{
sal_uInt32 nError = m_pData->m_pObjectShell->GetErrorCode();
throw task::ErrorCodeIOException( ::rtl::OUString(),
  
  uno::Reference< uno::XInterface >(),

nError ? nError : ERRCODE_IO_CANTREAD );
}
}
}

When I call it in the filter,
it goes into "if( m_pData->m_pObjectShell->GetMedium() )" statment and 
"throw DOUBLEINITIALIZATIONEXCEPTION()".

That depends. If you are developing an extension that should run on the
current stable release it's not a bad idea to use this code line for
development. But using OOB680 is definitely not recommended.

In terms of development I'd even consider the OOF680 branch as way old
and patches don't necessarily apply on SRC680 anymore. I'd recommend
a recent SRC680 milestone instead, currently the latest available being
SRC680_m219.

Why do you have to use such an old code base? I'd strongly recommend to 
update to f.e. OOF680 m18, the latest release. From my point of view it 
does not make sense to do development based on old code.

I don't understand why you need to write a filter that does the same as
the default filter. I assume that you have some additional code in your
filter that loads your own data and then wants to pass the storage to
the document so that it can load as it would to for the original format,
correct?

Yes, I add the fingerprints of the document's creator into the 
substorage when saving the document.
when opening it, I want to judge if the fingerprints are match the 
fingerprints of who open it ,if match loading the document as original 
format.

There's a new API especially for filters that create a legal ODF
document storage themselves and just want to hand it over to the document
model. It goes like this:

Sequence< Any > aArgs( 2 );
aArgs[0] <<= xDoc;
aArgs[1] <<= xStream; // the stream you have got!

Reference< XFilter > xSubFilter;
try
{
// mxMSF is the service factory you received in
// the ctor of your filter
xSubFilter = Reference(
mxMSF->createInstanceWithArguments(
OUString( RTL_CONSTASCII_USTRINGPARAM(  
"com.sun.star.document.OwnSubFilter" ) ),
aArgs ),
UNO_QUERY );
xSubFilter->filter( aDescriptor ); // the original descriptor
}
catch(Exception& )
{
// ...
}

I don't know if it works when the provided stream itself *is* an ODF
storage but you can try it out and tell us if it works. :-)


Sorry, there is no OwnSubFilter service in my openoffice, my openoffice
is based on the source of OOB680 .

I want to try an other way.
My idea is  as following:
1. use loadComponentFromURLto open the document in hidden mode.
2. copy the whole content and style from the  XComponent returned fronm 
loadComponentFromURL to the mxDesDoc which is set by setTargetDocument.

3. close the hidden document.

Can I do in the filter in this way?
Could you tell me how to copy the whole content and style from one 
document to another if this way works?

Thanks!

[dev] RE:[dev] question about use XStorag

[cokecola13574]

Hi!
   With your help ,the exoprt in filter works well.
But now I get some problem with importing the file that I export.

I implement the XImporter as following:
void SAL_CALL XXFilter::setTargetDocument( const Reference< XComponent >& xDoc 
) 
throw(IllegalArgumentException, RuntimeException)
{
mxDesDoc = xDoc;
m_bImport = sal_True;
}
sal_Bool SAL_CALL XXFilter::filter( const Sequence< PropertyValue >& 
rDescriptor ) 
throw (RuntimeException)
{
Window* pFocusWindow = Application::GetFocusWindow();

if( pFocusWindow )
pFocusWindow->EnterWait();

sal_Bool bRet ;
if( m_bImport )
bRet = implImport( rDescriptor );
else
bRet = implExport( rDescriptor );

if( pFocusWindow )
pFocusWindow->LeaveWait();

return bRet;
}

sal_Bool XXFilter::implImport( const Sequence< PropertyValue >& rDescriptor )
{
...
uno::Reference< document::XStorageBasedDocument > xDoc( mxDesDoc, 
uno::UNO_QUERY );///mxDesDoc is set by setTargetDocument

...

///I use loadFromStorage to load document
uno::Sequence< beans::PropertyValue > afArgs( 1 );
afArgs[0].Name = ::rtl::OUString::createFromAscii( "FilterName" );
afArgs[0].Value <<= ::rtl::OUString::createFromAscii( "writer8" );
/**xSourceStorage is read form InputStream, I remove the sub storage and it's 
odt format now */
xDoc->loadFromStorage( xSourceStorage, afArgs ); 
...
///End
when I open a document,it goes into the function implImport
but the function loadFromStorage don't load the document.
Is there other API or method that I can load the odt document in my filter ? 

Thanks!

Hi,

first thanks for fixing the problem with the mail client.
Now about the possible problem.

The problem is that you shouldn't use the URL, you must use the
outputstream that is provided to you. The framework opens a temporary
stream and finally copies it over the target file in the Commit() in
SfxObjectShell that you have quoted. The reason is simple: if something
goes wrong in the filter the original files isn't destroyed.

So even if you already create your file at the target location the
SfxObjectShell will overwrite it with all the content stored in the
output stream. In your case the stream is empty, thus the zero byte
length of the result.

Here's what a filter creating a storage should do:

- first create a temporary file
- get the XStream interface from it
- open a storage based on that stream
- copy the document into it
- add your substorage
- commit this storage(!)
- dispose of it
- copy from this stream to the XOutputStream from the arguments
- dispose of the TempFile

The content of the output stream is handled by the framework code. It
will close the stream and copy the bits if everything went fine.

Seeing your code I wonder whether we should add a "Stream" argument so
that you don't need to create the temporary copy. But for the time being
you should proceed as recommended.

Ciao,
Mathias

[dev] RE:Re: [dev] RE:[dev] question about use XStorage in filter

[cokecola13574]

Thanks all!Let me have a try.

Hello! 

  I'm chensuchun.I'm a newbie in devloping filter.I implement a filter for 
exporting and importing my own format file,whose format is based on odt.But I 
get some problems about filter.

the code of  function filter( const Sequence< PropertyValue >& rDescriptor ) is 
following:

xDoc = uno::Reference< document::XStorageBasedDocument >( mxSrcDoc, 
uno::UNO_QUERY );  ///mxSrcDoc is set by setSourceDocument()

save to a tmp storage use filter writer8
  xSourceStorage = uno::Reference< embed::XStorage >( 
xStorageFactory->createInstance(),
uno::UNO_QUERY );
  uno::Sequence< beans::PropertyValue > afArgs( 1 );
  afArgs[0].Name = ::rtl::OUString::createFromAscii( "FilterName" );
  afArgs[0].Value <<= ::rtl::OUString::createFromAscii( "writer8" );
  xDoc->storeToStorage( xSourceStorage, afArgs );

add a sub storage to the  xSourceStorage 

const ::rtl::OUString aSubStorageName ( RTL_CONSTASCII_USTRINGPARAM ( 
"SubStorage" ) );
   uno::Reference< embed::XStorage > xSubStorage = 
xSourceStorage->openStorageElement( aSubStorageName, 
embed::ElementModes::WRITE );

uno::Reference< beans::XPropertySet > xSubStoagePro( xSubStorage, 
uno::UNO_QUERY );
   xSubStoagePro->setPropertyValue( OUString::createFromAscii("MediaType"), 
makeAny(OUString::createFromAscii("SubMediaType")) );

..

///create the target storage

uno::Sequence< uno::Any > aArgs( 2 );
 aArgs[0] <<= aURL; get from rDescriptor 
 aArgs[1] <<= embed::ElementModes::READWRITE;
 uno::Reference< embed::XStorage > xTargetStorage( 
  xStorageFactory->createInstanceWithArguments( aArgs ),
uno::UNO_QUERY );


copy to target storage and commit

xSourceStorage->copyToStorage( xTargetStorage );
   bRet = sal_True;
   uno::Reference< XTransactedObject > xTransaction = 
uno::Reference< XTransactedObject >( xTargetStorage, UNO_QUERY );
   if( xTransaction.is() )
xTransaction->commit();

/dispose them

uno::Reference< lang::XComponent > xComponent1( xSourceStorage, uno::UNO_QUERY 
);
   OSL_ENSURE( !xSourceStorage.is() || xComponent1.is(), "Wrong storage 
implementation!" );
   if ( xComponent1.is() )
xComponent1->dispose();

   uno::Reference< lang::XComponent > xComponent2( xTargetStorage, 
uno::UNO_QUERY );
   OSL_ENSURE( !xTargetStorage.is() || xComponent2.is(), "Wrong storage 
implementation!" );
   if ( xComponent2.is() )
xComponent2->dispose();

End

After the execution of filter( const Sequence< PropertyValue >& rDescriptor ),

the target file is created and the size of the file is about 7K.

But after  executing the following code in sal_Bool SfxObjectShell::SaveTo_Impl:


  // transfer data to its destinated location
  // the medium commits the storage or the stream it is based on
RegisterTransfer( rMedium );
bOk = rMedium.Commit();

the size of target file becomes 0 K.

Why? 

Is some thing wrong in my filter( const Sequence< PropertyValue >& rDescriptor 
) function?

what should I do with the XStorage ? 

Any help and sugestion in identifying the missing pieces is appreciated.

Thanks

End
After the execution of filter( const Sequence< PropertyValue >& rDescriptor ),
the target file is created and the size of the file is about 7K.
But after  executing the following code in sal_Bool 
SfxObjectShell::SaveTo_Impl:

  // transfer data to its destinated location
  // the medium commits the storage or the stream it is based on
    RegisterTransfer( rMedium );
    bOk = rMedium.Commit();
the target file becomes 0K.
Why? 
Is some thing wrong in my filter( const Sequence< PropertyValue >& rDescriptor 
) function?
what should I do with the XStorage ? 
Any help and sugestion in identifying the missing pieces is appreciated.
Thanks

You may have noticed the ongoing discussion in another tyhread on this
mailing list with subject "Can we do more regression testing?".

> BTW, any suggestion is welcomed! Thanks in advance!

You'll find information about OOo automated test tools under
http://qa.openoffice.org/ooQAReloaded/AutomationTeamsite/ooQA-TeamAutomation.html

For general code tests that detect access of memory and such please see
http://wiki.services.openoffice.org/wiki/Valgrind

If you suspect some particular class to have leaking in the sense of
instantiations not destroyed, you may temporarily derive it from class
::rtl::DebugBase, see sal/inc/osl/diagnose.hxx

Some memory leaks you only find with an adapted memory manager and good
knowledge of the application to be able to ignore false positives (not
every apparent leak is an unintended real leak). You may compile
sal/rtl/source/alloc.c with debug=t

You should also build a non-product version (configure --enable-dbgutil)
for development and use OSL_ASSURE and similar macros to gather
information about your objects. These tests are executed in product
versions. Product and non-product builds can be done from the same
source tree, the output goes into different directories (without .pro
extension for the non-pro version). However, before configuring the
non-pro, backup your existing *Env.Set* files to not have them
overwritten.

[dev] question on testing �0�2tools to test the stability

[Canghua Qu]

Hi,All,

As we add some features and fixed some bugsof OOo, sometimes our new version 
is unstable for unknown reason. I want to know if OOo's developers or testers 
use any useful  testing �0�2tools to test the stability such as memory leak. 
And 
How to deal with such prolbems?

BTW, any suggestion is welcomed! Thanks in advance!

This is only needed for context menus. The menu bars are now specified

That's ok.

The xml file alone doesn't specify the language dependent text for the
menu entry. The are configuration files which define these language
dependent labels. Look at the "officecfg" project. It contains the
folder "registry/data/org/openoffice/Office/UI". There are two different
configuration files involved:
GenericCommands.xcu
Commands.xcu

If you add a command which is used by more than one application you
should add a node to the GenericCommands.xcu file. Otherwise to the
corresponding module dependent Commands.xcu file.
The key for the configuration entry must be the command name which, in
your case, is "WebHtml".

Yes, as I said above, UNO is powerful... But that example shows that it is far 
away from what I would call "spreading", "popular" or "widely accepted".

OK. My own order of priorities prevents me from working on this d-bus stuff in 
short or medium term. Nevertheless, we have here an opportunity for an 
unified application scripting framework, at least on Unix/Linux systems, my 
opinion is that we at OpenOffice.org should take it.

UNO does not compare exactly to D-Bus, since UNO is a full component model 
while D-Bus is more a matter of remote method invocation. However, they can 
be used for the same thing: remote control of an application.

 Speaking for SUN's StarOffice/OpenOffice.org Programmability Team (the
UNO group is part of it), at the moment there are no plans to support d-bus.

 Is someone outside SUN willing to work on this interesting topic?
Contributions would be greatly appreciated.

I see that you have had no answers..

First, you can not easily do this from VB. Your primary options are as 
follows:


* Export to a format supported by Calc (such as CSV)
* Write VB code to connect to OOo and then manually write the data into 
a Calc document.

* Export the data to an Excel file and then open it with Calc.

[dev] Question

[Jean SUZINEAU]

Hello,

I 'm about to release under LGPL a library which uses Open Office and I 
would like to get some advices before publishing it.


This library allows to access OpenOffice through Ole automation from a 
program written with Borland Delphi.
Furthermore, it allows to generate ".odt" text documents from a delphi 
dataset object.
The ".odt" is generated from an ".ott" template which can be customized 
by the end user, by the mean of user variables and predefined styles 
(one for each column in the text tables).

The ".ott" is generated by the library upon first execution.

I would like to release this library under the LGPL licence.
I contact you to get some advices before publishing this work.

I named the package "OpenOfficeReport" but may be I should give it 
another name ?. For now I don't find any other program with this name on 
the web.
What is the best mean to publish this work ? For now I think I'm going 
to open a new project on SourceForge.


For now you can download this library from a confidential url :
http://mars42.com/OpenOfficeReport/OpenOfficeReport_source.zip  for the 
source code
http://mars42.com/OpenOfficeReport/OpenOfficeReport.zip for the compiled 
executables
(the executables need Delphi 7 standard libraries, but I did not include 
them)


I work both as freelance and as employee for Batpro ( 
http://www.batpro.com/ ), a small company in Toulouse, France.
I use this library since autumn 2004 to produce various documents like 
invoices from delphi programs.


Yours sincerely,
Jean SUZINEAU

A functioning writer should not need any of these. For a full-featured

Yes, we should make the original file available always. But we do not need pay 
more attention to it, we can get it from DrawDocShell easily( by GetMedium() ). 
What we should do is to make sure it is openned if we need import something 
from it, and to clode it if we do not need it anymore. What is your meaning of 
\"Additionally import errors\", under slide show mode I get a refresh error 
what I have said in question 1, some errors else?

I have resolved the problem.In code base 680, there is a new module -- 
slideshow, it is responsible for showing the presentation. I found in func ** 
bool Presentation_Impl::prefetchSlide( sal_Int32 nPage ) **, they use bufferd 
mechanism( buffered 3 pages, previouse,current and next page ), so I import 3 
pages a time if they are unimportted in func ** void 
SlideshowImpl::slideChange() **.

Yes, but the PPT filter is reside on the PPT format of couse. We just only 
modify some codes in class PPTWriter and will not bring some side effects. But 
I am not familiar with PPT format :)

A delay load slide page mechanism might be a good thing for a PPT
viewer, but in case you are editing the file you will not save any time
rather it is leading to many difficulties as it is required that the
original file is always available and you have to determine if edited
slides have to be loaded from the original PPT document or from
something else. Additionally import errors will occur at a very late
time, you might get the error if you are just showing your presentation.

In my opinion the import of a PPT file is not finished as long as the
original PPT document is needed. There exist the possibility to store
changed slides only, but this requires deep knowledge of the PPT format
and it leads to the fact that you resides on the PPT format, and this is
something that nobody really wants.

[dev] question about improving the speed of openning .ppt file ( delay load slide page )

[蒋东进]

Hi,all

I have implemented delay load slide page in impress these days. Now I can 
import a BIG .ppt file in several seconds.
Here is my way: I modify func ** sal_Bool ImplSdPPTImport::Import() **, 
only complete load several pages( start 4-6 pages ) at import phase, for other 
pages I only import their notepage, but leave their masterpage and slidepage 
for delay loading when those pages are realy needed,eg display or operate.

Everything is ok but 2 questions:

1. Under slide show mode, if the previous/next page is not imported, I call 
my import func to import its masterpage and slidepage in func ** void 
SlideshowImpl::slideChange() **. My import func is executed well but the page 
still display blank, only if I forward or backward some times, the page is 
updated well. So I want to know how I can update the page immediately after 
call my import func?
Under source code base 1.04, I put my import func at the frant of ** void 
FuSlideShow::PrepareForPage( SdPage* pPage, BOOL bInitAnimObjs ) **,it works 
well. Now I change my source code base to 680m104, I get the problem. 

2. When I open a .ppt file, change something and save it, I must call my 
import func to import all those unimported pages before export it. So even we 
can import a BIG .ppt file in several seconds, but it will take more time( the 
same as import the whole .ppt file completely ) to wait the file be saved. I 
found ** sal_Bool PPTWriter::ImplCreateSlide( sal_uInt32 nPageNum ) ** is the 
func to export a slidepage, I want to know how I can only export those imported 
pages, for those unimported pages only copy their bytes from old file medium( 
inputstream ) to new file medium( outputstream )? In this way the export 
process will fast.

Thank you to read my question. Any comment and hint are welcome.

jiangdongjin

Hi jiangdongjin,
okay, it wasn't clear to me from your original mail that delay-loading
the images is sufficient for your case (in general, it won't be
sufficient to noticeably speed up PPT import - just try a 100 slide
document with lots of polygonal content...).

So my plan is, in the load phase, I only load some basic infomation
like width and height of the picture(I think only these are
necessary for formatting), then display.After that if I really need
some pictures(display or operation), I import it from input stream.
Yes, that's a lot easier than delay-loading of the whole
document. You'd have to extend the GraphicObject to be able to swap in
from streams with a given offset (and live with the fact that some
special-casing from the PPT import might no longer work - I vaguely
remember MS putting whole GIFs into PNG chunks).
HTH,
Hi,
I also think that delay-loading of images is not so difficult to
implement, but there are some obstacles to overcome:
- some graphics are compressed some are not
- especially ole objects needs to be placed into the correct storage
  environment
- currently we do not support all graphic attributes - sometimes
  images needs to be adjusted at load time
By the way delay-loading doesn't bring any benefit if you are just
converting files into the OOo format, because then you have to wait
until the model has been converted completely.

As I mentioned :
OOo impress imports all contents before displays, but MS Powerpoint only 
imports those needed;

I have tried to change the synchronous load mechanism but I failed :)
So many things I need to know and change. 

I found when open my test .ppt file(contains many jpg or bmp pictures), the 
most time-wasted points are those functions to load picture.
i.e.
ImportGIF(...)
ImportPNG(...)
ImportJPEG(...)
ImportXBM(...)
..
If I omit these functions, My test .ppt file opened as fast as MS 
Powerpoint(maybe 1-2 seconds slower), but all my pictures are missing.
So my plan is, in the load phase, I only load some basic infomation like width 
and height of the picture(I think only these are necessary for formatting), 
then display.After that if I really need some pictures(display or operation), I 
import it from input stream.

Is my method feasible? Thanks!

best regards,
jiangdongjin

Hi jiangdongjin,

as you've found out by yourself, not streaming out the images to temp
files hogs huge amounts of memory (and is therefore not an
option). 

Your first item is actually the crucial point here: as our PPT import
is just that, an import, we really have to fully read the file
content. This is because our own, internal representation of the
document content (the 'model') must be complete before anything can be
displayed. There are currently no mechanisms to lazy-load only the
first slide, and the remainder only on demand.

Changing that would be quite some work, as it would require large
refactorings to integrate PPT import more tightly with the drawing
layer model.

HTH,

[dev] question about improving the speed of openning .ppt file

[jiangdongjin]

Hi all,

These days I am doing the work to improve the speed of openning a .ppt file 
which contains many jpg or bmp pictures. 
 I found use MS Powerpoint and OOo impress to open the same .ppt file(contains 
many jpg or bmp pictures),OOo impress
 is much more slower than MS Powerpoint.In my test,MS Powerpoint open my test 
.ppt file in 3-4 seconds, but for OOo 
 it is 1-2 minutes.
 
 I have tracked the process of importing a .ppt file, here is the process:
 
 ..
 ImplSdPPTImport::Import()
 SdrPowerPointImport::ImportPage(...)
 SvxMSDffManager::ImportObj(...)
 SvxMSDffManager::ImportGraphic(...)
 SvxMSDffManager::GetBLIP(...)
 SvxMSDffManager::GetBLIPDirect(...)
 GraphicFilter::ImportGraphic(...)
 Graphic::SetLink(...) // * here save picture 
data into a temp file
 SdrGrafObj::ForceSwapOut()
 GraphicObject::FireSwapOutRequest()
 GraphicObject::ImplAutoSwapOutHdl(...)
 GraphicObject::SwapOut() //  here again swap out picture 
data to temp file
 ..
 
 To my opinion, OOo impress opens .ppt file slower because of:
 1. It imports all contents before displays, but MS Powerpoint only imports 
those needed;
 2. It create too many temp files for those pictures embeded in slide pages, 
but MS Powerpoint do nothing about this.
 
 Then I do some tests, first I omit the function Graphic::SetLink(...). In the 
case open my .ppt file(contains many jpg or
 bmp picture), the speed raise 30%-40% and only several temp files created. 
Everything looks ok except the peak memory
 is twice. Maybe too many picture data in memory?
 
 So my question is:
 1. Why we must import all things before to display it? Maybe operation speed 
will fast but load speed is too slow;
 2. Can I maintain the input sream( .ppt file stream ) all the time? So I can 
import any thing when I real need it;

 Thank you to read my question, and I need your help. Any comment and hint are 
welcome.
 
best regards,
jiangdongjin

For submitting the script using the issue tracker, it is unclear which

"qa", "tools", and "utilities", but a stand-alone script like this

I'm currently spending some time investigating those options. I'm seeing
what I can do about using com.sun.star.awt.* because I definitely like
following the OOo look and feel but you are right, it's definitely a lot of
work. If I spend a lot of time with the API docs I imagine I could do it but
I'm hunting for some code examples right now so I can make it easier to
understand. I like the concept of how the new java wizards work and I've
been bouncing around in there some more but with no documentation on the
process of how to do one from XML to source generation etc. I might punt on
that.

Re: [dev] Question regarding unused code removal

[Matt Prazak]

I ended up writing a short Bourne shell script that does the best I
know how to do when looking at just the binaries in the program/
directory.  While there is no guarantee that the reported symbols are
completely unused, they are clearly canidates for the *_DLLPRIVATE
macros.  Once made private, a per-module lint-like analysis could
finish determining whether a symbol is truly unused.

The script outputs two files.  The first file contains the symbols that
are defined but not used by any UNDEF nor used in any relocation table.
 The second file contains symbols that are defined but are used only
within a relocation table (i.e., only the defining binary uses it).

These results might be useful towards run-time linking optimization, as
the first file reports about 15,000 symbols and the second file reports
about 47,000 symbols that could be made private.  Given that there are
over 100,000 symbols exported in all the binaries, this means there is
a potential for reducing the number of exported symbols by several
percent.  I hesitate to say the full 15,000 could be privatized,
because many of the unused symbols are constructors, for example, which
probably have an intended purpose.

What is the best way to submit this script to OO.org for second
opinions and to see whether it would be useful towards run-time
optimization?

Re: [dev] Re:[dev] Question regarding unused code removal

[Matt Prazak]

Your approach appears more throrough than what I've been attempting. 
My hypothesis so far is that a fair amount of information can be
obtained straight from the binaries in the program/ directory without
analyzing the source code.

One thing I've learned is that the the ELF symbol tables and relocation
tables do provide a lot of information, including revealing some of the
symbols that are used internally within the binaries.  However, there
is a lot of room for source-based analysis like your tool or the
commercial C++ lint tools.

Re: [dev] Re:[dev] Question regarding unused code removal

Hi Matt,
your approach is flawed in the way that a symbol which is defined *and* 
used in one shared library is not flagged "UNDEF" in this library, but 
still be exported from the library if it's possibly used elsewhere. Thus 
you get a lot of exported symbols without equivalent "UNDEF" for shared 
library internal stuff.

This is an unfortunate consequence of the C++ standard which has no 
concept of shared library "internal" classes/methods/functions.

We do something about this: Please look for all the *_DLLPUBLIC and 
*_DLLPRIVATE macros in our headers. These macros use non standard 
compiler extensions to mark symbols as "public" or "hidden". "Hidden" 
symbols will not be exported from a shared library. This has at least 
three benefits: a better API definition (think of encapsulation), 
smaller binaries and last not least better startup performance because 
relocations are cheaper if direct binding can be used.

There is a great paper about the working of shared libraries by Ulrich 
Drepper: http://people.redhat.com/drepper/dsohowto.pdf

We probably got quite a bit of dead code in OOo but it is not easily 
found. I think the best approach would be to do some extensive coverage 
studies, identify possibly dead code, use a cross referencer to find all 
references whrere a symbol is used and determine if this is also dead 
code. The call to remove the dead code must then be made by the 
responsible developer, only he/she can tell if that symbol may not 
possibly be referenced by some code outside OOo (ie a third party 
component).

Well, I'm still learning about this.  The current method I'm working on
is to use the elfdump utility in Solaris to extract the symbol tables
from all the *.so* and *.bin files in the program/ directory, then
extract the UNDEF and non-UNDEF entries into two text files, grep out
all the symbols I think can be ignored, and generate a list of all the
defined symbols that don't have UNDEF counterparts.  Right now, I have
a shell script that attempts to do this.  Unfortunately, the best I've
done so far indicates about 66,000 unused symbols (an improvement over
75K, though).
I'm not sure if this approach is flawed in some ways, but it seemed
like the most direct approach to the problem.  If anyone knows more
about ELF binaries, a critique of the above approach would be helpful,
especially since my knowledge of C++ is pretty stale.

Thanks for the replies.  Actually, the number is more like 75,000.  I
think I read the wrong number yesterday to get the 85,000.  I did
include all the WEAK references from elfdump, and it looks like
eliminating them might take out another 7,000 symbols.  Also, I'll feed
in the .bin files, which will knock out some more.

I'm using Solaris 10 and Studio 10, so I guess the GCC symbols won't
apply.  Sidenote:  compiling on Solaris10/Studio10 was pretty tricky,
especially since I was trying to use --enable-debug at first (notes
about this are under issue 42285 at the oo.org website).

One thing is that some symbols appear to be part of the normal class
interfaces (e.g., constructors) that are unused but probably shouldn't
be removed, so the only thing I can think would work reliably is to go
through each canidate symbol and determine via find/grep where it
occurs and whether it is important.

Over the next few days, I'll see if the number of symbols can be shrunk
further.

Hi,

85, 000 symbols seems to be a lot. But, maybe ...I noticed that lot of code 
need to be cleaned up (I am talking about 1.1.2, I've no idea about 2.0).
It would be a good idea to remove unused code some day because, without talking 
about performances, it can be really misleading for the newcomer (I remember

Some more reasons why the number is that high but (some of) the symbols

-  If you are doing this on Linux, and are including weak definitions, 
you will get lots of symbols that are (by necessity) exported weakly 
from multiple objects, like the _ZTI* symbols needed for proper GCC 
exception handling.

-  The default linking behaviour on Unix is that if some non-static 
C/C++ function is only used internally within an object (shared object 
or executable), it is nevertheless exported from that object.  Some 
parts of OOo use this default behaviour.

The main problem with this, however, is that this is really a big
number of symbols to go through.  Are there any guidelines or
suggestions for how to find a starting point?  If this is workable and
I find something probably worth removing, is it best to simply nominate
that function for removal or is it better to submit a patch that strips
it out?

Re: [dev] Question regarding unused code removal

Hi Matt,
I think you will be surprised how much less symbols you will get after 
including the .bin files, just because these are the starting points :)

icu).

can probably be reduced somewhat)
