Understanding Bug 143148 - "Use pragma once instead of include guards"
This bug is about refactoring header files in the LibreOffice codebase to use #pragma once instead of traditional include guards (#ifndef, #define, #endif).

When writing C++ header files, include guards prevent multiple inclusions of the same file, which can lead to compiler errors.
Traditional include guards look like this:
example:

#ifndef MY_HEADER_FILE_H // If not defined
#define MY_HEADER_FILE_H // Define it

// Code inside the header file

#endif // End of include guard

These prevent multiple inclusions, but they are verbose and error-prone (e.g., developers might accidentally use the same macro name in different files).

#pragma once is a modern, simpler alternative to include guards. Instead of using #ifndef and #define, you just write:

#pragma once

Find header files that use traditional include guards and replace them with #pragma once.

Steps to Solve the Issue:

LibreOffice is a large codebase. You need to identify header files (.h or .hpp) that use #ifndef include guards.

The best way is to search for #ifndef in the codebase.

Modified the files

Removed the #ifndef and #define lines.

Replaced them with #pragma once.

Removed the #endif at the end.

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.

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"
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#130857 qt weld: Defer QDialog deletion
d8761f3 
Instead of deleting the QDialog owned by the
QtInstanceDialog in the QtInstanceDialog dtor
right away by calling std::unique_ptr<QDialog>::reset,
instead mark the object for deletion by calling
QObject::deleteLater [1] on the dialog object, which schedules
the object for deletion when control returns to the event
loop.

Also switch QtInstanceDialog::m_pDialog from a unique_ptr
to a plain QDialog*.

This fixes crashes seen with the current qtbase git dev branch
after qtbase commit

    commit 84a5f50c7766c99f62b22bb4388137e0aa8dd13d
    Author: Shawn Rutledge <shawn.rutledge@qt.io>
    Date:   Tue Nov 12 10:04:31 2024 +0100

        Move QContextMenuEvent synthesis from QWidgetWindow to QWindow

The crash was quite reproducible for me by running LO with the qt6 VCL
plugin and SAL_VCL_QT_USE_WELDED_WIDGETS=1 (to enable use of
native Qt widgets), opening the "Help" -> "About LibreOfficeDev"
dialog and closing it by clicking the "Close" button with the
left mouse button.

Backtrace of the crash:

The segfault happens when calling

    d->maybeSynthesizeContextMenuEvent(event);

, i.e the virtual QWindowPrivate::maybeSynthesizeContextMenuEvent.
This is because the QWidgetWindow object and its QWidgetPrivate
have already been deleted when processing an earlier event
triggered by the mouse click, see backtrace below.

Not deleting the object right away but marking it for deletion later
makes sure the object is still valid when the event gets processed,
and then deleted afterwards.

Backtrace of how the QWindowPrivate object got deleted earlier
(reverse-debugged with rr) - see frame 17 for the dtor (i.e. the
code that was adjusted in this commit now to fix the problem):

tdf#164899 Don't call SystemWindow::SetNotebookBar recursively
f3d640b 
Fix crash with the backtrace below when opening sample doc
attachment 198795 from tdf#164885 with macros enabled
when using the qt6 VCL plugin.

sfx2::SfxNotebookBar::StateMethod (frame 80) calls
SystemWindow::SetNotebookBar (frame 79) which calls
ImplBorderWindow::SetNotebookBar (frame 78) which
first disposes and clears the existing
ImplBorderWindow::mpNotebookBar and then creates
a new one.

However, calling the NotebookBar ctor triggers
a recursive call to sfx2::SfxNotebookBar::StateMethod
and SystemWindow::SetNotebookBar again (see frame 4).

When that one calls SystemWindow::SetNotebookBar,
it skips the logic to set a new NoteBookbar, but
the following call to the getter
SystemWindow::GetNotebookBar returns null, because
the previous ImplBorderWindow::SetNotebookBar (in frame 78, s. above)
hasn't finished yet.

For now, prevent such recursion from happening by
returning early in sfx2::SfxNotebookBar::StateMethod
if the NoteBookBar is already in the process of
getting set up.

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

    Date:   Thu Dec 5 11:06:48 2024 +0000

        tdf#164093 tdf#157001 a11y: Improve menu window disposal

Avoid disposing parent window before its child by not using
the SwAnnotationWin, but its parent as the popup menu
parent.

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

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

    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.

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

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.

Backtrace:

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

tdf#168500 sfx2: Prevent recursion when creating child win
184bc3c 
After

    commit 94442bd94e504b067efd0b992525b53fc660f114
    Author: Michael Weghorn <m.weghorn@posteo.de>
    Date:   Tue Aug 5 11:07:25 2025 +0200

        tdf#163802 a11y: Fully initialize SpellDialog before showing

, triggering the spell check dialog in Impress
for an empty presentation would result in infinite
recursion e.g. with the gtk3 or gen VCL plugins
on Linux, because the initialization of the
svx::SpellDialogChildWindow triggers a message dialog
asking whether to start spell check from the beginning
(s. frame #252 in below backtrace).
For gtk3 and gen, that dialog triggers processing
of pending events, which triggers an update of the
child windows (s. frame #230), which triggers the logic to
create the spell check child window again (as it isn't
shown yet).

(For qt6, that problem wasn't seen, because synchronously
showing the message dialog doesn't trigger processing
of pending events.)

Fix the problem by detecting cases where a child
window is already in the process of being created,
and return early in that case.

Change SfxWorkWindow::CreateChildWin_Impl to return
a bool result indicating whether the child window
was created or not, and evaluate that in the callers.

Sample backtrace for the gtk3 VCL plugin:

tdf#130857 qt weld: Block toggled signal for new entry
33eea7b 
When the TreeView has special checkboxes enabled,
block signals while calling QStandardItem::setCheckable
for the item in the first column. This prevents triggering
the QAbstractItemModel::dataChanged signal which would trigger
weld::TreeView::signal_toggled from
QtInstanceTreeView::handleDataChanged for the newly
inserted row.
Since the row is new, there is no logical change
from a previous value from the weld API perspective.

This fixes a crash otherwise seen with upcoming
commit
