Question about weak reference list inside java bridge code.

2009-11-22T22:47:40Z

We got a problem like this, one of the L2 entry list keep growing consume
too much memory.

module jurt

package com.sun.star.lib.uno.environments.java;

the cleanUp member function of class Registry.

// must only be called while synchronized on map:
private void cleanUp() {
for (;;) {
Level2Entry l2 = (Level2Entry) queue.poll();
if (l2 == null) {
break;
}
// It is possible that a Level2Entry e1 for the OID/type
pair
// (o,t) becomes weakly reachable, then another Level2Entry
e2
// is registered for the same pair (o,t) (a new Level2Entry
is
// created since now e1.get() == null), and only then e1 is
// enqueued. To not erroneously remove the new e2 in that
case,
// check whether the map still contains e1:
String oid = l2.getOid();
Level1Entry l1 = getLevel1Entry(oid);
if (l1 != null && l1.get(l2.getType()) == l2) {
removeLevel2Entry(oid, l1, l2);
}
}
}

All those weak reference Level2Entry entries are invalid, the condition
(l1.get(l2.getType()) == l2) keeps cleanUp function from removing them from
the list.

I think if this
// It is possible that a Level2Entry e1 for the OID/type
pair
// (o,t) becomes weakly reachable, then another Level2Entry
e2
// is registered for the same pair (o,t) (a new Level2Entry
is
// created since now e1.get() == null), and only then e1 is
// enqueued.
happened once then there is no way the condition (l1.get(l2.getType()) ==
l2) can be true again, because get(l2.getType()) always return the first
element in the list, but queue.poll() return the newly released weak
reference which can not be the first one in the list.

If weak reference list cleanup mechanism is correct, could please give some
possible reasons could cause the growing problem of L2 entry list.

Thanks.

listbox events

2009-11-21T07:14:47Z

Hi,

I'm having a strange problem that affects only certain versions of ooo 3.1.1

In practice, having a listbox model, if you set the SelectedItems
property, on some ooo version the itemStateChanged event of the ListBox
is raised.

The problem does not affect OOo vanilla version (sun build) but affects
the ooo packaged from Ubuntu.

you can test with the code below (you'll need to prepare a simple dialog
with a listbox before)

Now, my question is:
what is the correct behaviour:
OOo by sun: the event is NOT raised if you modify the selection from the
model but it is raised if the user modify the selection manually.

OOo Ubuntu 9.10: the event is alwais raised

IMHO the first is correct or at least is the most used, because I have
never observed the second in old ooo versions.

thanks
Paolo M

REM ***** BASIC *****

Sub Main
oDlg = CreateUnoDialog(DialogLibraries.Standard.Dialog1)
oDlg.Model.ListBox.StringItemList = Array(1,2,3,4,5)

'this line raises the event but only on certain versions
oDlg.Model.ListBox.SelectedItems = (Array(0)) '****

oDlg.execute
End Sub

'manually binded to the itemstateChanged event of the listbox
Sub ListBox_itemStateChanged(oEvent As Object)
Print "halo!"
End Sub

This is an interesting test case of the future of the toolkits such as
libpurple and XUL.

http://instantbird.com/

This is a great way to see if OOo can grow into new modules maybe by
encapsulating the libraries such as the project management project. For
example something like the Planner app (project management in Gnome) and
the OOo toolkit. Althought I am not sure if XULRunner and UNO represent
the same stack.

Also a side project could be a better collaboration environment using
libpurple which also works on all 3 OS.

I hava read und write access to the file. In OpenOffice i can open the

are you sure that you have write access to the file? Can you open it for
editing with the same instance of OOo with the same OOo user profile
that you are using for your loadComponentFromURL call?

Are you talking about "ReadOnly" or about "Hidden"?

loadcomponentfromrul with whitespace bug?

2009-11-18T02:54:41Z

Hello,

I try to open a document. In the Path are whitespace. I replace the
whitespace with '%20', for example
file:///C:/Dokumente%20und%20Einstellungen/twc/TWC/Documents/1258539328921.odt.

If the ReadOnly property is true or the property is not set, it works
well. If the property ist false a IllegalArgumentException is throw.

I have no idea whether socket communications can be done in OOoBasic.
But I would know how to create a small Windows application that can read
a string from a file and send it to a port on a given IP address. You
can then use SHELL() from OOoBasic to run that application when you need
to update the display. This should be fast enough since you are using it
for something equivalent to subtitles on TV.

But first you should get communications going with the LED display. Try
doing "telnet 10.10.10.1 10001" where 10.10.10.1 is the IP address of
the display. I then believe you should be able to see the text you write
on the LED display. If that works for you I can help you with a
dedicated application for sending strings. Feel free to write to me in
private at the address "jan <at> jan-holst.dk".

Help with ip output stream from Basic macro in OOo Calc on XP

2009-11-14T04:50:56Z

Please forgive me writing to you on this e-mail address, but I find the
OOo world overwhelming from my limited knowledge of computing theory and
terminology, and I haven't found how or where to submit a request for
help. I am looking for a snippet as described below. Is this the sort
of thing that some kind person might write for me? If not, can you
please suggest where I might put my request? I would be grateful for
any assistance.

I am happy to explain why I want it, but it's a long story -
essentially, it's for writing to an LED display hung over a theatrical
stage, using a WiFi connection from a laptop. If it works reliably, I
intend to make the code freely available, as this sort of requirement is
becoming increasingly in demand to help the hard-of-hearing and for
language barriers. Current commercial software is either very expensive
or too crude. However, I need to implement the connection before I worry
about how to publish the code! Anyway, here is the request.

Help with ip output stream from Basic macro in OOo Calc on XP.

I am attempting to send lines of text to a remote display device. As a
first step, I have written a set of macros to extract the data I want
from a spreadsheet and save each line as a file on disc in the required
format. I did this by copying bits of code I found, with a very
superficial understanding of how it all works. I am very grateful to
all those who contribute examples and help.

My next step is to send the data to the display device instead of disc
file. The instruction I have from the device manufacturer is -

"Use a socket component and transmit the data string to port 10001 on
the IP address of the display device."

I have no idea how to do this, and have not found examples that I
understand. The display only listens and does not respond - does that
mean I should use UDP rather than TCP? Below is my current output
routine. I would be grateful for suggestions on how to convert or
replace it.

Sub DisplayText(FilePath as String, DataString as String)
rem Currently writes a file to disc - overwriting the
previous.
rem derived from Useful Macro Information. For
OpenOffice.org.

sure i totally agree but it is as it is at the moment. I don't see that
we be able to make the big shot. The only thing we can do is to improve
the available controls step by step and can try to improve the overall
usability. This includes hopefully a layout manager some day ;-)

Well, the problem is that Java/Swing programmers are used to create
their own user interface elements, so these limitations are quite serious.

I've heard that RedOffice 4.5 will support deep and custom changes of UI
using extensions, so if their code gets to the core (someday), then it
should be easier to persuade people to do the switch.

Hi

The moast of the community members know me... for the rest, I like to
say helo. My name is Raphael Bircher, 29 Years old, from Switzerland. I
contribute since November 2005 for OpenOffice.org. My main part is QA.

I'm here, because I like to start a extension project for sport coachs.
A.t.m. the preparation of a training is a hard work. If you do it
seriosly, that's a load of paper work. This i like to simplify.

I'm here for the tecnical part. It's my first extension, and I think, I
will need your help sametimes. ;-)

Thanks and Greetings
Raphael

it is correct that the UNO awt toolkit has limitations but it is the
best way to integrate in the office and to avoid problems.

You can use the dialog editor in the office to do the initial design.
Export the dialog description in your extensions Java project and use
via dialog provider ... Appropriate handler have to be implemented and
registered to handle the different events. See the SDK samples and the
DevGuide docu.
With OOo 3.2 it is also possible to import dialog descriptions and
modify it again with the dialog editor.

There is still a lot of space for improvements and volunteers are always
welcome ;-)

As far as I know, there is none. If you want to have the native look
(which is different under different OSes and graphical managers), use
the AWT via UNO. However, this is a bit cumbersome if you display
something more complex than a message box. And you cannot really
implement anything new in the UI (no new UI elements by overriding
classes, as far as I know). No wonder most extension developers don't
use it...

Hi Juergen,

it's sad that OOBean ist not maintained anymore. It's a nice feature and
has it's uses :).

I can recommend it to certain extent since I'm working with it right now
and it's quite stable and offers nice features. Of course not everything
is perfect and some methods shouldn't be used but overall it's useable.

I'm not yet familiar with the OO build env but I'm definitly looking
into it at some point in the future when theres more freetime :) I'll
definitly get back to your support offering by that time ;).
And staying with the curent interface should be no problem for the first
few changes.

I'm currently writing for Windows platforms. Didn't test my work on
Linux yet but that's something I'm looking forward to in the near future.

Re: Error messages / Exception handling

Hi Steffen,

the OOBean is not really maintained for a long time and i would say it
never reached a state where it was really finished. Today i would of
course never suggest to use it because of too many problems that have to
be solved first.

I don't know the code in detail but i know that every developer who
worked on it started to make it better ...

As i mentioned the OOBean is not really maintained and if you have
interest to help out here i will help and support you.

If you are familiar with the OO build env you can start to improve the
error handling and we can discuss your changes. The only thing that i
would suggest is that you keep the interface stable at the beginning.
Further improvements on this level should be postponed to later.

By the way on which platform are you working?

Error messages / Exception handling

2009-11-13T00:29:52Z

Good morning,

before i start, let me get this clear: It's awesome that you guys do all
that work here. OO is a great product and I defintly appreciate the work
you all have put into it.

Yesterday I encountered several problems while programming with OOBean
and decided to download the source code to get a better understanding
how things are handled inside OO. I solved all my problems through
reading the code so thumbs up here :).
But one thing that bugged me while reading the code was error handling
in the packages.
I knew that the error messages in OO weren't great and always thought
this was due to lazy programming ;) or sometimes there are no better
alternatives. But after reading the code I have to say it's definitly
more of a lazy programming problem when it comes down to error handling
rather than availabilty of alternatives
.
One example:
com.sun.star.comp.beans.LocalOfficeConnection.parseUnoUrlWithOfficePath

The method parses an UnoURL. If everything goes right a state-variable
will be set to 7 and after parsing this state value will be used for
checking if everythings correct. If not, an error will be thrown.
Errors occure on invalid URLs of course and there are several different
errors. All are "catched" in some way since the state value will be set
to a negative number so the check at the end will fail. I counted 6
error states, all indicated through negative numbers.
Well, the problem is: at the end there is only a check if state != 7. An
error will be thrown stateing that the UNO Url is invalid. The 6
different error codes are not used at all. No info on what is invalid
even though the error states could be used to inform the user what was
wrong.
I mean, there is already a kind of exception handling built in, but it
is not used. Why even bother with 6 different error codes if they are
not used for something good?

Of course I didn't check all the source code since most of my problems
could be solved by reading some snippets of the OObean package but I
know for sure, that most exceptions are not really informative compared
to other APIs. And maybe it's a bad example because the method isn't
even used anymore or whatever, I didn't check that. I also don't want to
blame one programmer or make the feature look bad or something like
that. It's just difficult to understand why there is no better exception
handling overall.
Most of the time if something goes wrong, I get an Runtime Error and
that's it. Almost never theres more information given.

I mean, of course I'm able to trace it back anyway. And after reading
some bunch of code and researching the web I get the information I need
to solve the problem, but a more precise exception handling would be
great too.

If I insulted someone with this, I'm sorry. I just wanted to bring this
up since exception handling in OO bothered me and former colleagues for
quite a while now. Maybe it's a food for thought for some of you or a
start for a discussion how it could be made better :) .
Or maybe I just made everyone mad at me :D
Feedback would be appreciated anyway ;).

Steffen Börsig

It give False as result.
It works with HSQLDB, or MySQL 5.1.40 with OOo native driver for MySQL.

IDL references from the Wiki -> via IDL tags

2009-11-11T05:17:04Z

Hi,

this can be seen more as a reminder to make use of the IDL tags, see
http://wiki.services.openoffice.org/wiki/Wiki_maintenance/IDLTagExtension
for detailed info.

When we moved the Developer's Guide into the wiki we thought about a way
how we could achieve the useful IDL tags. The tags that get
automatically converted into links to the related type in the generated
IDL reference. In the end the IDLTagExtension was developed that allows
exactly the same functionality.

PLEASE whenever you want or have to reference an IDL type please use one
of the IDL tags to create a link automatically. It will help our users
and developers to find the appropriate information faster and it will
help to improve the overall navigation between the documentation
(guides, examples, tutorials, ...) in the wiki and the type reference.

Thanks

Hi Carsten.

Thanks for the explanation. At least I am no longer confused.

I was trying to change settings to either change the button icon
according to an ON/OFF state or enable/disable one of two buttons
according to ON/OFF state. I have settled with just having both buttons
visible always and then flashing a notification when the button is used
without effect - e.g. pressing the "Turn OFF" button while in the OFF
state would notify the user that it's no use trying to turn things off
that are already off.

Cheers

Hi Jan,

What you see is intended design and correct. An add-on toolbar is
defined by a XCU-file and have no settings which can be changed. This is
related to the fact that changes have to be stored in the user layer.
Unfortunately if you deinstall an extension these user layer data won't
be removed. That would mean that your add-on toolbar won't be removed,
too. Therefore we decided to disable settings for add-on toolbars. If
you want to circumvent this design, what I cannot recommend, then you
can use the configuration API to make direct changes to your Addons.xcu
file. Please be aware that you and your users would see the negative
effects that I described before!

You can enable/disable button if you have a DispatchProvider that
controls the commands behind the buttons. This is a very complex task if
you want to do it in Basic.

I don't know what features the current UNO Python implementation
provides, but would guess that it supports all necessary things.

Carsten

Re: loadcomponentfromurl

Mikhail is right, an important piece of documentation is missing here
and i renew my request that we document filter specific settings
somewhere. A wiki page showing the names that have to be used via API
and all filter specific settings. These settings depends on the filter
implementation and should be documented for each filter.

Today we have only a list of filter names somewhere in the framework
wiki section.

Hi Wei Min,

As I have written in one of the previous emails, I would suggest to make
the type detection explicitly to get the required filter name. And in
case you get "Text (encoded)" filter, please add the filter options
containing the encoding.

The problem with filter options is that there seems to be no
documentation regarding them. According to source-code the following
property in the MediaDescriptor might work in case of "Text (encoded)"
filter.
Prop.Name = "FilterOptions"
Prop.Value <<= "UTF8"

Before you start with the TypeDetection usage, please try just to add
the filter options property in MediaDescriptor and try it with the
problematic documents. Just to be sure that the options are accepted in
this format.

Best regards,
Mikhail.

Hi all,

Thanks for your responses.

Let's assume that indeed those files are not "legitimate" .doc files. If someone creates a text file and renames it as .doc, the Writer encoding text dialog will pop out a UI. If I do choose a encoding such as UTF-8, it will be able to open the text file with no problems and the text will be readable. This is what i want to do programatically, to open with a specified encoding without using the pop-out UI.

Is it possible to do this?

Cheers,

Wei Min

Hi Bernard,

this is a good question and i will clarify it. I assume that the
deprecated tag is wrong

Thanks to bring this up.

Service SpreadsheetDocumentSettings

2009-11-08T00:15:10Z

Hi all,

Service css.sheet.SpreadsheetDocumentSettings is marked as deprecated since SDK 1.1.

How can it be deprecated and have new properties added since OOo 3.0 ?
[optional, property] boolean IsLoaded;
[optional, property] boolean IsUndoEnabled;
[optional, property] boolean IsAdjustHeightEnabled;
[optional, property] boolean IsExecuteLinkEnabled;
[readonly, optional, property] com::sun::star::awt::XDevice ReferenceDevice;

Regards
Bernard

Sorry, I was wrong in my last comment.
Indeed the text filter still wins sometimes by unknown formats, although
actually the filter selection dialog should be shown. And MSWord filter
has no filter options dialog.

It is probably more interesting to take a look to the document. I
suspect that Bernard is right and the document is no valid .doc document.

Mikhail.

It means these are not real .doc or .ppt files.
Microsoft sometimes creates simple (not formatted) text files as .doc
Probably it uses Windows encoding ( e.g. Windows 1252 for European text).
Open those files with user interface, you will be requested an encoding. If you
can't find a correct one, how could you find it by program?

Another case is when a file is corrupted : no solution here.

Bernard

i don't think so. A valid .doc file is auto detected and the word filter
doesn't have a filter options dialog as far as i know. It looks more
like the scenario that Ariel has described.

Maybe a complete code snippet could help to understand ...
