How to convert a Multi-Page Text file to PNG, for example:- I have a Text document of 5 pages and I want to convert that into PNG. By default, it's giving a PNG of only 1st page. How to get the PNG file for ith page using LibreOffice.

I used the PageRange filter like this, but it does not work, it's also giving the PNG only for 1st page.

Also, I'm not able to generate multiple PNGs for multi-page word files using the LibreOffice Application

CLI:-

soffice --convert-to 'png:writer_png_Export:{"PageRange":{"type":"string","value":"2-"}}' test.odt

JAVA:-

conversionProperties[0] = new com.sun.star.beans.PropertyValue();
conversionProperties[0].Name = "FilterName";
conversionProperties[0].Value ="writer_png_Export";

conversionProperties[1] = new com.sun.star.beans.PropertyValue();
conversionProperties[1].Name = "PageRange";
conversionProperties[1].Value ="2-";

related tdf#156683 a11y: Dispose FrameSelectorImpl a11y children
79cc574 
Don't just invalidate, but also dispose the a11y children
in `FrameSelectorImpl::~FrameSelectorImpl`.

This fixes a crash on exit that's reproducible with
the gtk3 VCL plugin e.g. like this (maybe some
steps aren't even needed):

1) start LO Writer with the gtk3 VCL plugin
2) right-click, select "Character" > "Character"
   in context menu
3) switch to "Font Effects" tab
4) press space key with focus in the font color combobox
   to open the popup
5) use Tab key to get to the view of colors
6) move around with arrow keys a bit
7) close the dialog and Writer

Reverse-continuing to `atk_object_wrapper_dispose`
(frame LibreOffice#10 in the below backtrace) in rr
showed the involved a11y object:

    uno::Reference to (svx::a11y::AccFrameSelectorChild *) 0x5557832b9150

Backtrace (somewhat similar to the one in tdf#156683):

tdf#157304 Use normalized selection indices as string indices
489985a 
The start index of the selection can be larger than the
end index.
Take that into account when using these indices to
calculate the index and character count to copy
the relevant substring using `OUString::copy`.

Without this, running the tdf#157304 macro would trigger
an assert due to invalid indices being used.

tdf#157304 Use normalized selection indices as string indices
59a1402 
The start index of the selection can be larger than the
end index.
Take that into account when using these indices to
calculate the index and character count to copy
the relevant substring using `OUString::copy`.

Without this, running the tdf#157304 macro would trigger
an assert due to invalid indices being used.

Backtrace:

Prevent attempts to create UCB content from .component URIs
c36cba3 
After commit 86c6822 (tdf#96401:
allow to detect a broken ZIP package, 2023-11-26) impl_openStream
is called from TypeDetection::impl_detectTypeFlatAndDeep for URIs
like ".component:Bibliography/View1". For some reasons, sometimes
GIO UCP tries to handle these URIs; failing that, it shows an

Thank Stephan Bergmann for the help understanding it and deciding
how to fix it.

tdf#158947 sw: Don't unrelatedly overwrite system clipboard on paste
cb9513c 
In `SwTransferable::RemoveDDELinkFormat`, only update the
clipboard content with this `SwTransferable` after removing
the `SotClipboardFormatId::LINK` from the supported formats
if the `SwTransferable` was the clipboard content before
already.

Doing so always would unrelatedly overwrite what was previously
copied from another application to the clipboard for the
tdf#158947 scenario of pasting clipboard content of another
application over a selection when using the Qt-based VCL plugins
on Wayland (s. backtrace below that shows how the clipboard content
was overwritten, frame #17 is the method changed in this
commit).

My assumption why the clipboard content is explicitly overwritten
at all is to make sure that the system clipboard on some platforms
gets notified about the change in supported formats/mime
types after removing one. But that isn't necessary when the
transfer data modified here aren't the current clipboard content
in the first place.

Backtrace for how clipboard content was previously overwritten
for the tdf#158947 scenario with the qt6 VCL plugin on Wayland:

tdf#158947 sw: Don't unrelatedly overwrite system clipboard on paste
0750cac 
In `SwTransferable::RemoveDDELinkFormat`, only update the
clipboard content with this `SwTransferable` after removing
the `SotClipboardFormatId::LINK` from the supported formats
if the `SwTransferable` was the clipboard content before
already.

Doing so always would unrelatedly overwrite what was previously
copied from another application to the clipboard for the
tdf#158947 scenario of pasting clipboard content of another
application over a selection when using the Qt-based VCL plugins
on Wayland (s. backtrace below that shows how the clipboard content
was overwritten, frame #17 is the method changed in this
commit).

My assumption why the clipboard content is explicitly overwritten
at all is to make sure that the system clipboard on some platforms
gets notified about the change in supported formats/mime
types after removing one. But that isn't necessary when the
transfer data modified here aren't the current clipboard content
in the first place.

Backtrace for how clipboard content was previously overwritten
for the tdf#158947 scenario with the qt6 VCL plugin on Wayland:

tdf#158947 sw: Don't unrelatedly overwrite system clipboard on paste
45d1f6d 
In `SwTransferable::RemoveDDELinkFormat`, only update the
clipboard content with this `SwTransferable` after removing
the `SotClipboardFormatId::LINK` from the supported formats
if the `SwTransferable` was the clipboard content before
already.

Doing so always would unrelatedly overwrite what was previously
copied from another application to the clipboard for the
tdf#158947 scenario of pasting clipboard content of another
application over a selection when using the Qt-based VCL plugins
on Wayland (s. backtrace below that shows how the clipboard content
was overwritten, frame #17 is the method changed in this
commit).

My assumption why the clipboard content is explicitly overwritten
at all is to make sure that the system clipboard on some platforms
gets notified about the change in supported formats/mime
types after removing one. But that isn't necessary when the
transfer data modified here aren't the current clipboard content
in the first place.

Backtrace for how clipboard content was previously overwritten
for the tdf#158947 scenario with the qt6 VCL plugin on Wayland:

tdf#158947 sw: Don't unrelatedly overwrite system clipboard on paste
7f8f7f3 
In `SwTransferable::RemoveDDELinkFormat`, only update the
clipboard content with this `SwTransferable` after removing
the `SotClipboardFormatId::LINK` from the supported formats
if the `SwTransferable` was the clipboard content before
already.

Doing so always would unrelatedly overwrite what was previously
copied from another application to the clipboard for the
tdf#158947 scenario of pasting clipboard content of another
application over a selection when using the Qt-based VCL plugins
on Wayland (s. backtrace below that shows how the clipboard content
was overwritten, frame #17 is the method changed in this
commit).

My assumption why the clipboard content is explicitly overwritten
at all is to make sure that the system clipboard on some platforms
gets notified about the change in supported formats/mime
types after removing one. But that isn't necessary when the
transfer data modified here aren't the current clipboard content
in the first place.

Backtrace for how clipboard content was previously overwritten
for the tdf#158947 scenario with the qt6 VCL plugin on Wayland:

The fix appears to be to just not call back into the in-destruction FmFormView -
... - SdrMarkView - ... - SdrPaintView - ... deep-inheritance object, by not
initiating any further triggerLazyInvalidate from within
~ObjectContactOfPageView.

tdf#159735 a11y: Dispose win accessible with VCLXWindow
9c64ae3 
`Window::dispose` takes care of disposing its
accessible as well.

However, `VCLXWindow::dispose` was explicitly unsetting
the accessible before disposing its `vcl::Window`, resulting
in it not getting disposed, in turn resulting in a crash on exit
for the tdf#159735 case.

Potentially related:

    commit 5aa60be
    Date:   Wed May 12 11:33:06 2021 +0200

        fix leak in VCLXWindow

        which is a little tricky because dispose() can be called from either
        side (vcl::Window or VCLXWindow)

Before that commit, setting a nullptr accessible happened
in the `VCLXWindow` dtor, which is meant to get called after
the `vcl::Window` got disposed in `VCLXWindow::dispose`.
(In the Linux bibisect repo, the commit before that one is fine
and at that commit, the tdf#159735 comment 5 scenario even
crashes in step 3 already.)

Don't unset the `vcl::Window`'s accessible any more in
`VCLXWindow::dispose`, but do that after disposing it in
`vcl::Window::dispose` instead, which seems to be the
natural place to do that anyway.

Backtrace of crash:

    Thread 1 received signal SIGSEGV, Segmentation fault.

tdf#159735 a11y: Dispose win accessible with VCLXWindow
1c64b4e 
`Window::dispose` takes care of disposing its
accessible as well.

However, `VCLXWindow::dispose` was explicitly unsetting
the accessible before disposing its `vcl::Window`, resulting
in it not getting disposed, in turn resulting in a crash on exit
for the tdf#159735 case.

Potentially related:

    commit 5aa60be
    Date:   Wed May 12 11:33:06 2021 +0200

        fix leak in VCLXWindow

        which is a little tricky because dispose() can be called from either
        side (vcl::Window or VCLXWindow)

Before that commit, setting a nullptr accessible happened
in the `VCLXWindow` dtor, which is meant to get called after
the `vcl::Window` got disposed in `VCLXWindow::dispose`.
(In the Linux bibisect repo, the commit before that one is fine
and at that commit, the tdf#159735 comment 5 scenario even
crashes in step 3 already.)

Don't unset the `vcl::Window`'s accessible any more in
`VCLXWindow::dispose`, but do that after disposing it in
`vcl::Window::dispose` instead, which seems to be the
natural place to do that anyway.

Backtrace of crash:

    Thread 1 received signal SIGSEGV, Segmentation fault.

tdf#159735 a11y: Dispose win accessible with VCLXWindow
97a2f97 
`Window::dispose` takes care of disposing its
accessible as well.

However, `VCLXWindow::dispose` was explicitly unsetting
the accessible before disposing its `vcl::Window`, resulting
in it not getting disposed, in turn resulting in a crash on exit
for the tdf#159735 case.

Potentially related:

    commit 5aa60be
    Date:   Wed May 12 11:33:06 2021 +0200

        fix leak in VCLXWindow

        which is a little tricky because dispose() can be called from either
        side (vcl::Window or VCLXWindow)

Before that commit, setting a nullptr accessible happened
in the `VCLXWindow` dtor, which is meant to get called after
the `vcl::Window` got disposed in `VCLXWindow::dispose`.
(In the Linux bibisect repo, the commit before that one is fine
and at that commit, the tdf#159735 comment 5 scenario even
crashes in step 3 already.)

Don't unset the `vcl::Window`'s accessible any more in
`VCLXWindow::dispose`, but do that after disposing it in
`vcl::Window::dispose` instead, which seems to be the
natural place to do that anyway.

Backtrace of crash:

    Thread 1 received signal SIGSEGV, Segmentation fault.

tdf#159735 a11y: Dispose win accessible with VCLXWindow
72d4979 
`Window::dispose` takes care of disposing its
accessible as well.

However, `VCLXWindow::dispose` was explicitly unsetting
the accessible before disposing its `vcl::Window`, resulting
in it not getting disposed, in turn resulting in a crash on exit
for the tdf#159735 case.

Potentially related:

    commit 5aa60be
    Date:   Wed May 12 11:33:06 2021 +0200

        fix leak in VCLXWindow

        which is a little tricky because dispose() can be called from either
        side (vcl::Window or VCLXWindow)

Before that commit, setting a nullptr accessible happened
in the `VCLXWindow` dtor, which is meant to get called after
the `vcl::Window` got disposed in `VCLXWindow::dispose`.
(In the Linux bibisect repo, the commit before that one is fine
and at that commit, the tdf#159735 comment 5 scenario even
crashes in step 3 already.)

Don't unset the `vcl::Window`'s accessible any more in
`VCLXWindow::dispose`, but do that after disposing it in
`vcl::Window::dispose` instead, which seems to be the
natural place to do that anyway.

Backtrace of crash:

    Thread 1 received signal SIGSEGV, Segmentation fault.

related tdf#160176 qt: Create dummy Qt widget in main thread
bf4ec3b 
Always run `QtGraphics_Controls::getNativeControlRegion`
in the main thread, as it may create a dummy `QLineEdit`
(see the `ControlType::MultilineEditbox` and
`ControlType::Editbox` cases) and creating Qt widgets
is only allowed in the main thread.

Without the following scenario runs into an assert
with a current Qt 6 dev debug build when using the
qt6 VCL plugin:

1) open sample document attachment 193089
   from tdf#160176
2) enable Form Design Toolbar
3) switch to Design mode
4) select label next to "Labelfield2" label
5) right-click, "Control Properties"
6) type anything for the help text and tab
   to the next UI element

Backtrace:

gtk4 a11y: Handle when there's no a11y context
0855109 
Handle the case where `XAccessible::getAccessibleContext`
returns an empty reference, as e.g.
`VCLXWindow::getAccessibleContext` does when already
disposed.

Fixes an assert/crash seen with the gtk4 VCL plugin
when experimenting with missing menu item handling
in Writer's "Tools" -> "Bibliography Database",
expanding the search filter menu, then closing the dialog
and LO altogether.

Backtrace:

        tdf#162696 qt weld: Do GUI things in main thread

, the destruction of `QtInstanceDialog::m_pDialog` (that
previously implicitly happened due to it being a
`std::unique_ptr`) also needs to happen in the main
thread.

Otherwise, it triggers this assert with a debug Qt build
for the tdf#162696 of installing an extension via drag'n'drop
into the start center:

tdf#164072 sw annotation: Use menu parent that outlives menu
fc2394d 
When opening the popup menu by right-clicking on a Writer
comment and selecting "Delete All Comments", the SwAnnotationWin
(`mrSidebarWin`) gets disposed while the popup menu and its associated
MenuFloatingWindow are still alive. With the menu floating window
being a child of the SwAnnotationWin, that would trigger the
below assert since

browsebox a11y: Don't report EditBrowseBoxTableCell as its own parent
ced8912 
The EditBrowseBoxTableCell ctor's first param is the
parent, the second one is the owner.

The EditBrowseBoxTableCellAccess is the owner, but not the
parent, which means that the params were passed in the
wrong order.

Since EditBrowseBoxTableCellAccess::getAccessibleContext
returns the EditBrowseBoxTableCell, this would result
in the EditBrowseBoxTableCell reporting itself as
its own parent.

This results in infinite recursion when trying to walk
up the a11y hierarchy starting at the EditBrowseBoxTableCell.

Switch the order of the first 2 params to fix that.

This addresses a preexisting issue that was now
triggering a crash as described in

    commit 261dd0fd48b2e2c284485c25feade854154595aa

        browsebox a11y: Use comphelper::OAccessibleComponentHelper

        [...]

        Sample scenario for BrowseBox:

        1) Start Base, create a new database
        2) With the "Tables" section enabled, click on
           "Create Table in Design View..."
        3) in Accerciser's treeview of the LO a11y, navigate
           through the a11y objects of the table and its children

        A quick test with Orca [...] triggered
        a crash for the BrowseBox case.

        The underlying problem is a preexisting issue however, and
        will be addressed in an upcoming commit.

Sample backtrace:

    Thread 1 received signal SIGSEGV, Segmentation fault.

browsebox a11y: Use recursive mutex
71d1432 
Fixes a deadlock seen for this scenario
with the qt6 VCL plugin on Linux:

1) start Orca
2) Start Base, create a new database
2) With the "Tables" section enabled, click on
   "Create Table in Design View..."
3) click around in the table, use Tab key to move focus

AccessibleBrowseBoxAccess::commitEvent (frame 20 in the below
backtrace) locks the mutex, and then
AccessibleBrowseBoxAccess::getAccessibleContext (frame 8) tries to
acquire the mutex again and deadlocks.

Locking in AccessibleBrowseBoxAccess::commitEvent was added in

browsebox a11y: Use recursive mutex
252c31f 
Fixes a deadlock seen for this scenario
with the qt6 VCL plugin on Linux:

1) start Orca
2) Start Base, create a new database
2) With the "Tables" section enabled, click on
   "Create Table in Design View..."
3) click around in the table, use Tab key to move focus

AccessibleBrowseBoxAccess::commitEvent (frame 20 in the below
backtrace) locks the mutex, and then
AccessibleBrowseBoxAccess::getAccessibleContext (frame 8) tries to
acquire the mutex again and deadlocks.

Locking in AccessibleBrowseBoxAccess::commitEvent was added in

    commit 67158da

browsebox a11y: Use recursive mutex
98afc79 
Fixes a deadlock seen for this scenario
with the qt6 VCL plugin on Linux:

1) start Orca
2) Start Base, create a new database
2) With the "Tables" section enabled, click on
   "Create Table in Design View..."
3) click around in the table, use Tab key to move focus

AccessibleBrowseBoxAccess::commitEvent (frame 20 in the below
backtrace) locks the mutex, and then
AccessibleBrowseBoxAccess::getAccessibleContext (frame 8) tries to
acquire the mutex again and deadlocks.

Locking in AccessibleBrowseBoxAccess::commitEvent was added in

    commit 67158da

browsebox a11y: Use recursive mutex
5284be6 
Fixes a deadlock seen for this scenario
with the qt6 VCL plugin on Linux:

1) start Orca
2) Start Base, create a new database
2) With the "Tables" section enabled, click on
   "Create Table in Design View..."
3) click around in the table, use Tab key to move focus

AccessibleBrowseBoxAccess::commitEvent (frame 20 in the below
backtrace) locks the mutex, and then
AccessibleBrowseBoxAccess::getAccessibleContext (frame 8) tries to
acquire the mutex again and deadlocks.

Locking in AccessibleBrowseBoxAccess::commitEvent was added in

    commit 67158da
    Date:   Fri Oct 4 14:22:22 2024 +0100

gtk4: Own the string when freeing it
38024bc 
As the GVariant format string doc says [1] about
pointers:

> The `&` character is used to indicate that serialised data should be
> directly exchanged via a pointer.
>
> Currently, the only use for this character is when it is applied to a
> string (ie: `&s`, `&o` or `&g`). For `g_variant_new()` this has absolutely no
> effect. The string is collected and duplicated normally. For
> `g_variant_get()` it means that instead of creating a newly allocated copy
> of the string, a pointer to the serialised data is returned. This
> pointer should not be freed. Validity checks are performed to ensure
> that the string data will always be properly nul-terminated.

Therefore, freeing the string with

    g_free(pLabel);

is incorrect and resulted in a crash when starting Writer with
the gtk4 VCL plugin, s. backtrace below.

Use just "s" instead of "&s" for the format string to get a
string copy that is owned and can be freed.

(Dropping the `g_free` might be an alternative and avoid
a string copy, but it's not instantly clear to me whether
using "a pointer to the serialised data" is safe without
digging any deeper what exactly that means.)

Backtrace:

    free(): invalid pointer

tdf#130857 qt weld: Make sure .ui file is processed in main thread
fbca764 
QWidgets may only be created in the GUI/main thread, and
that is what happens when processing the .ui file.

Therefore, ensure this is always run in the main thread.

One case observed where this was not the case was the crash
recovery dialog getting created after Impress had crashed
due to an assert being hit somewhere in the QtMultimedia
library in a non-main thread.

Backtrace:

tdf#164380 qt: Ensure at least one MIME type for drag'n'drop
479dd32 
Ensure that the QMimeData subclass set for the QDrag used
for drag and drop reports at least one supported MIME type.
Report a dummy "application/x.libreoffice-internal-drag-and-drop"
one if there is no other one.
(The string used for the MIME type is of no particular meaning,
any value would do.)

This prevents the issue seen with qt6 on Wayland that a
drag and drop operation is cancelled when no formats/MIME types
are reported.

The "wl_data_offer" Wayland protocol [1] is probably relevant
here:

> A wl_data_offer represents a piece of data offered for transfer by
> another client (the source client). It is used by the copy-and-paste and
> drag-and-drop mechanisms. The offer describes the different mime types
> that the data can be converted to and provides the mechanism for
> transferring the data directly from the source client.
>
> (...)
>
> For objects of version 3 or newer, this request determines the final
> result of the drag-and-drop operation. If the end result is that no mime
> types were accepted, the drag-and-drop operation will be cancelled and
> the corresponding drag source will receive wl_data_source.cancelled.

(Further analysis on Qt and Wayland library/protocol level
might give more insights, but this is sufficient at least for now.)

Example backtrace for how QtWaylandClient::QWaylandDrag::cancel
(in Qt's qtwayland module) got called previously when releasing
the mouse after dragging a slide to a different position in
the Impress slide sorter (on Debian testing in a Plasma Wayland
session, kwin-wayland 4:6.3.4-3, Qt self-compiled from git dev):

tdf#164380 qt: Ensure at least one MIME type for drag'n'drop
27446a3 
Ensure that the QMimeData subclass set for the QDrag used
for drag and drop reports at least one supported MIME type.
Report a dummy "application/x.libreoffice-internal-drag-and-drop"
one if there is no other one.
(The string used for the MIME type is of no particular meaning,
any value would do.)

This prevents the issue seen with qt6 on Wayland that a
drag and drop operation is cancelled when no formats/MIME types
are reported.

The "wl_data_offer" Wayland protocol [1] is probably relevant
here:

> A wl_data_offer represents a piece of data offered for transfer by
> another client (the source client). It is used by the copy-and-paste and
> drag-and-drop mechanisms. The offer describes the different mime types
> that the data can be converted to and provides the mechanism for
> transferring the data directly from the source client.
>
> (...)
>
> For objects of version 3 or newer, this request determines the final
> result of the drag-and-drop operation. If the end result is that no mime
> types were accepted, the drag-and-drop operation will be cancelled and
> the corresponding drag source will receive wl_data_source.cancelled.

(Further analysis on Qt and Wayland library/protocol level
might give more insights, but this is sufficient at least for now.)

Example backtrace for how QtWaylandClient::QWaylandDrag::cancel
(in Qt's qtwayland module) got called previously when releasing
the mouse after dragging a slide to a different position in
the Impress slide sorter (on Debian testing in a Plasma Wayland
session, kwin-wayland 4:6.3.4-3, Qt self-compiled from git dev):

tdf#164380 qt: Ensure at least one MIME type for drag'n'drop
ddcc64d 
Ensure that the QMimeData subclass set for the QDrag used
for drag and drop reports at least one supported MIME type.
Report a dummy "application/x.libreoffice-internal-drag-and-drop"

(The string used for the MIME type is of no particular meaning,
any value would do.)

This prevents the issue seen with qt6 on Wayland that a
drag and drop operation is cancelled when no formats/MIME types
are reported.

The "wl_data_offer" Wayland protocol [1] is probably relevant
here:

> A wl_data_offer represents a piece of data offered for transfer by
> another client (the source client). It is used by the copy-and-paste and
> drag-and-drop mechanisms. The offer describes the different mime types
> that the data can be converted to and provides the mechanism for
> transferring the data directly from the source client.
>
> (...)
>
> For objects of version 3 or newer, this request determines the final
> result of the drag-and-drop operation. If the end result is that no mime
> types were accepted, the drag-and-drop operation will be cancelled and
> the corresponding drag source will receive wl_data_source.cancelled.

(Further analysis on Qt and Wayland library/protocol level
might give more insights, but this is sufficient at least for now.)

Example backtrace for how QtWaylandClient::QWaylandDrag::cancel
(in Qt's qtwayland module) got called previously when releasing
the mouse after dragging a slide to a different position in
the Impress slide sorter (on Debian testing in a Plasma Wayland
session, kwin-wayland 4:6.3.4-3, Qt self-compiled from git dev):

tdf#167274 svx: Set drawing area for ImageMap dialog early
fdffaac 
For the gtk3 VCL plugin, calling weld::DrawingArea::set_size_request
can trigger the creation of the corresponding a11y object,
which wants to access the drawing area to determine its states.

Therefore, call the base class implementation to set the
drawing area right at the start of IMapWindow::SetDrawingArea,
as is done elsewhere (e.g. in CuiGraphicPreviewWindow::SetDrawingArea).

This fixes a crash with the below backtrace seen after

    commit 62b8ebe
    Author: Michael Weghorn <m.weghorn@posteo.de>
    Date:   Wed Feb 12 13:15:52 2025 +0100

        GraphCtrl a11y: Use comphelper::OAccessibleComponentHelper

when opening the "Tools" -> "ImageMap" dialog in Impress or Writer
with the gtk3 VCL plugin.

tdf#167274 svx: Set drawing area for ImageMap dialog early
221dd89 
For the gtk3 VCL plugin, calling weld::DrawingArea::set_size_request
can trigger the creation of the corresponding a11y object,
which wants to access the drawing area to determine its states.

Therefore, call the base class implementation to set the
drawing area right at the start of IMapWindow::SetDrawingArea,
as is done elsewhere (e.g. in CuiGraphicPreviewWindow::SetDrawingArea).

This fixes a crash with the below backtrace seen after

    commit 62b8ebe

        GraphCtrl a11y: Use comphelper::OAccessibleComponentHelper

when opening the "Tools" -> "ImageMap" dialog in Impress or Writer
with the gtk3 VCL plugin.

sd console: Fix deadlock when exiting presentation mode
be60f7a 
Since

    commit 380bd85
    Date:   Tue Jun 24 11:21:04 2025 +0200

        [API CHANGE] remove css::drawing::framework::XView

, starting an Impress presentation in a dual screen setup
with presenter console enabled, then existing the presentation
resulted in a deadlock with the below backtrace, because
WeakComponentImplHelperBase::dispose (frame 9)
locks the base class's UnoImplBase::m_aMutex and then
sdext::presenter::PresenterSlideShowView::disposing (frame 8)
tries to lock it again.

Use the existing lock passed as a method param and pass it
down to the called methods instead. Add an assert
it is actually a lock for the correct mutex.

tdf#130857 qt weld: Hold SolarMutex in QtInstanceWindow::eventFilter
81db441 
This fixes an assert seen in a WIP branch to support the
"Manage Changes" dialog when the dialog was open in the
previous run when LO crashed, and then restarting LO.

Also add an assert that this is running in the main thread.

gtk4: Own the string when freeing it
bc15aa8 
As the GVariant format string doc says [1] about
pointers:

> The `&` character is used to indicate that serialised data should be
> directly exchanged via a pointer.
>
> Currently, the only use for this character is when it is applied to a
> string (ie: `&s`, `&o` or `&g`). For `g_variant_new()` this has absolutely no
> effect. The string is collected and duplicated normally. For
> `g_variant_get()` it means that instead of creating a newly allocated copy
> of the string, a pointer to the serialised data is returned. This
> pointer should not be freed. Validity checks are performed to ensure
> that the string data will always be properly nul-terminated.

Therefore, freeing the string with

    g_free(pLabel);

is incorrect and resulted in a crash when starting Writer with
the gtk4 VCL plugin, s. backtrace below.

Use just "s" instead of "&s" for the format string to get a
string copy that is owned and can be freed.

(Dropping the `g_free` might be an alternative and avoid
a string copy, but it's not instantly clear to me whether
using "a pointer to the serialised data" is safe without
digging any deeper what exactly that means.)

Backtrace:

    free(): invalid pointer

(<https://ci.libreoffice.org/job/lo_ubsan/3648/>) as seen during (recently
introduced) CppunitTest_sd_uiimpress testTdf166647_userpaint::TestBody.

(I assume that there is a pre-existing race accessing
CallbackCaller::mxConfigurationController, and that an additional
CallbackCaller::stop accessing it doesn't make things worse, so left that point
alone for now.)

gtk4: Own the string when freeing it
3e75a87 
As the GVariant format string doc says [1] about
pointers:

> The `&` character is used to indicate that serialised data should be
> directly exchanged via a pointer.
>
> Currently, the only use for this character is when it is applied to a
> string (ie: `&s`, `&o` or `&g`). For `g_variant_new()` this has absolutely no
> effect. The string is collected and duplicated normally. For
> `g_variant_get()` it means that instead of creating a newly allocated copy
> of the string, a pointer to the serialised data is returned. This
> pointer should not be freed. Validity checks are performed to ensure
> that the string data will always be properly nul-terminated.

Therefore, freeing the string with

    g_free(pLabel);

is incorrect and resulted in a crash when starting Writer with
the gtk4 VCL plugin, s. backtrace below.

Use just "s" instead of "&s" for the format string to get a
string copy that is owned and can be freed.

(Dropping the `g_free` might be an alternative and avoid
a string copy, but it's not instantly clear to me whether
using "a pointer to the serialised data" is safe without
digging any deeper what exactly that means.)

Backtrace:

    free(): invalid pointer
