Previously the client would only learn the mime type of what was being
dropped on it once the drop occurred. To enable more sophisticated
filtering of drag & drop, we now pass along the list of mime types being
dragged to the client with each MouseMove event.
(Note that MouseMove is translated to the various Drag* events in LibGUI
on the client side.)
If a widget accept()'s a "drag enter" event, that widget now becomes
the application-wide "pending drop" widget. That state is cleared if
the drag moves over another widget (or leaves the window entirely.)
We were using the "accept" flag on the event to break out of the
bubbling loop, but this had lasting consequences since all events that
bubbled too far came out looking as if someone had accepted them.
If an event is ignored by everyone, it should appear ignored.
These events allow widgets to react when a drag enters/leaves their
rectangle. The enter event carries position + mime type, while the
leave event has no information.
AT_SECURE is set in the auxiliary vector when we execute setuid/setgid
programs.
In those cases, we do not want to read environment variables that
influence the logic of the dynamic loader, as they can be controlled
by the user.
Previously, when trying to parse the location info of a member
variable, we asserted that the location info of its parent is of type
'Address'.
However, there are cases where we cannot compute the location info of
the parent (for example - because we do not yet support the type of
debug info generated for it).
In those cases, it is better to just leave the location info of the
member variable empty instead of crashing.
DebugSession now makes the loader stop after loading the libraries,
and parses the loaded libraries of the program before continuing its
execution.
DebugSession now also supports inserting a breakpoint at a given symbol
or source position.
Additionally, DebugInfo now takes the base address of its object into
consideration.
If set, the dynamic loader will perform a software breakpoint after
loading all libraries, and just before jumping to the main entry point.
This allows a debugger to inspect the loaded libraries before the
program starts executing.
SpaceAnalyzer: Partially address code review changes.
- Use GUI::CommonActions::make_about_action().
- Pass large arguments by const reference instead of by value.
- Mark const functions as such.
- Add newline at end of SpaceAnalyzer.af
- Use full words instead of abbreviations in variable names.
- Use application's namespace instead of 'TreeMap'.
- move() certain assignments.
- Use member declaration initialization.
- Initialize TreeNode* member of QueueEntry.
- Rewrite find_mount_for_path to return MountInfo* instead.
- Rename ITreeMap and ITreeMapNode to TreeMap and TreeMapNode.
- Replace ext suffix with rect suffix for rectangles.
SpaceAnalyzer: Further address code review and coding style.
- Remove get prefix from accessor functions.
- Layout algorithm in its own function, with callback.
- Remove nullptr comparisons.
- Store lstat errors in error_accumulator.
- Use Rect::shatter.
- Use Rect's orientation based functions.
SpaceAnalyzer: Make sort_children_by_area const qualified.
Unlike zero-extend moves, the upper bytes are not just zeroed,
but rather are based on the sign bit of the source, which means
if the source is tainted, so should the upper bytes be.
Linux accepts both -r and -R, but the BSDs only like -R, and
dR POSIX also only mentions -R. So make -R the canonical flag.
Keep -r available as an alias for -R.
This patch implements the "remove irrelevant boxes" and "generate
missing child wrappers" parts of table fixup.
"Generate missing parents" is left as a task for our future selves.
