This patch begins integrating LibJS into LibWeb. Document holds the
JS::Interpreter for now, and it is created on demand when you first
call Document::interpreter().
We also add a simple "alert()" function to the global object.
We also clean up some old references to the old G prefixed GUI classes
This also fixes a potential bug with using: C_OBJECT_ABSTRACT(GAbstractButton)
instead of C_OBJECT_ABSTRACT(AbstractButton)
There were two issues with this code:
- The result of the readlink() call was checked incorrectly for errors.
- This code shouldn't return because otherwise it leaves the GUI buttons
uninitialized below, causing RefPtr asserts to trigger when the dialog
tries to access the buttons later on.
Now that add() returns a WidgetType&, we can't rely on the parent of a
GUI::Dialog to still keep it alive after exec() returns. This happens
because exec() will call remove_from_parent() on itself before
returning.
And so we go back to the old idiom for creating a GUI::Dialog centered
above a specific window. Just call GUI::Dialog::construct(), passing
the "parent" window as the last parameter.
Since the returned object is now owned by the callee object, we can
simply vend a ChildType&. This allows us to use "." instead of "->"
at the call site, which is quite nice. :^)
This patch adds two new API's:
- WidgetType& GUI::Window::set_main_widget<WidgetType>();
This creates a new main widget for a window, assigns it, and returns
it to you as a WidgetType&.
- LayoutType& GUI::Widget::set_layout<LayoutType>();
Same basic idea, creates a new layout, assigns it, and returns it to
you as a LayoutType&.
The selected option was stored in a captured stack variable which was
long gone by the time we looked at it, so this dialog didn't really
behave the way you'd expect. Put it in a member instead. :^)
Now it actually defaults to "a < b" comparison, instead of forcing you
to provide a trivial less-than comparator. Also you can pass in any
collection type that has .begin() and .end() and we'll sort it for you.
This feels a lot more consistent and Unixy:
create_shared_buffer() => shbuf_create()
share_buffer_with() => shbuf_allow_pid()
share_buffer_globally() => shbuf_allow_all()
get_shared_buffer() => shbuf_get()
release_shared_buffer() => shbuf_release()
seal_shared_buffer() => shbuf_seal()
get_shared_buffer_size() => shbuf_get_size()
Also, "shared_buffer_id" is shortened to "shbuf_id" all around.
Also, we have now two new resolutions - 1368x768 and 1366x768.
The 1366x768 resolution is currently not supported but is good
for testing a failed resolution setting.
This patch allows roll notes to be of different sizes. This necessitates
a new internal representation of time. BPM and time signatures are
mostly implemented but not exposed.
Roll notes are now sample-accurate and the grid is aligned to 60 BPM
4/4. The roll is divided by the time signature raised to some power of
2, giving the musical divisions of (in the case of 4/4) 16, 32, 64 etc.
Before, our timing was derived from the buffer size and we relied on
that to implement delay. Delay has been rewritten to be sample-granular.
It's now exposed as the proper "divisions of a beat".
Something to be wary of is that the last buffer in the loop is also used
for the start of the next loop. In other words, we loop mid-buffer. This
means we write WAVs with a tiny bit of silence due to breaking the loop
after filling half a buffer.
The data structure for the roll is an array of SinglyLinkedLists of
RollNotes. Separating by pitch (via the array layout) makes insertion
much simpler and faster. Using sorted lists (and thus
SinglyLinkedListIterators) to do lookups is very quick as you know the
sample of the next note and can just compare it to the current sample. I
implemented this with HashMaps and the cost of lookups was abysmal. I
also tried a single SinglyLinkedList and the insertion code got even
more complicated than it already is.
This patch adds a new column to the per-process memory regions view in
SystemMonitor. It's a scaled view of the underlying pagemap of a region
that tells you which chunks of the region are resident/null/zero.
If a directory is renamed or deleted before 'make clean', git will
delete the Makefile but leave all of the object and dependency files
around. When make would try to recurse into that directory from the
wildcard, it would error out since there is no Makefile.
