DWARF line number information, if generated, is stored in the
.debug_line section of an object file.
The information is encoded as instructions for a VM that is defined in
the DWARF specification.
By executing these instructions, we can extract the encoded line number
information.
We allow the ref-counting parts of an object to be mutated even when the
object itself is a const.
An important detail is that we allow invoking 'will_be_destroyed' and
'one_ref_left', which are not required to be const qualified, on const
objects.
Previously, drag and drop would only work when dragging between node
items on a DirectoryView. This commit makes it possible to drag files to
the empty area of the DirectoryView and copy files more easily between
windows.
This allows us to run "run-tests -g" for testing with GC after every
heap allocation. This may flush out bugs that would otherwise not
occur if GC'ing only occasionally.
A MarkedValueList is basically a Vector<JS::Value> that registers with
the Heap and makes sure that the stored values don't get GC'd.
Before this change, we were unsafely keeping Vector<JS::Value> in some
places, which is out-of-reach for the live reference finding logic
since Vector puts its elements on the heap by default.
We now pass all the JavaScript tests even when running with "js -g",
which does a GC on every heap allocation.
These strings would be applied when inserted into the buffer, but are
not shown as part of the suggestion.
This commit also patches up Userland/js and Shell to use this
functionality
On the first tab, only complete the token without suggesting extra
stuff, and on further tabs, show suggestions.
Except in one case where the completion is all in the buffer, then
we show the suggestions, but do no completion.
When a drag operation is accepted, we don't check whether the source
nodes contain the destination directory. This could trigger an unwanted
recursive copy.
If the selection is empty, the model index will be invalid and the file
system model will return the root directory path by default. This causes
the file manager to jump to the root directory when the currently
selected item on the tree view is deselected.
Normally we focus any window that's added to the window stack. However,
for WindowType::Desktop this gets annoying since if the desktop manager
comes up after other GUI processes have already started, it steals the
focus from them.
Solve this by only auto-focusing desktop windows if they are the very
first window added.
