FooConstructor::construct() is no longer a dummy but now generates
either code to throw an exception (for interfaces without constructor)
or code to construct the wrapper and its impl object.
Constructor overloads are not currenly handled, but that's not something
we need right now anyway. Instead of regular create() this uses a new
static function create_with_global_object() and passes the WindowObject,
which may be needed - e.g. for XMLHttpRequest, which has an IDL and
JavaScript constructor with no arguments, but needs a DOM::Window in its
create().
Function::length() is computing the right function length based on its
parameters, but we never called it - instead the *function name length*
was being used, which is obviously wrong. How silly! :^)
By default, a Window has a minimum size of 50x50 - ComboBox lists aren't
always this tall. We now set the minimum height of the ComboBox Window
according to the height of three items, or the total height of all the
items in the list, whichever is smaller.
This means there is no longer any unpainted space in the list window
due to the shortfall between the ListBox widget and Window heights,
and the ComboBox list window always remains a comfortable height for
viewing. :^)
Tool windows are secondary windows with a smaller title bar. The sit on
the layer above normal windows, and cannot be minimized.
These are intended for complex yet non-modal interactions with the
content of a primary window, such as find/replace windows, property
windows, etc.
Minimum window size can now be customised and set at runtime via the
SetWindowMinimumSize WindowServer message and the set_minimum_size
LibGUI::Window method. The default minimum size remains at 50x50.
Some behind-the-scenes mechanics had to be added to LibGUI::Window to
ensure that the minimum size is remembered if set before the window is
shown. WindowServer sends a resize event to the client if it requests a
size on create that's smaller than it's minimum size.
POSIX explicitly allows providing nullptr's, and our __pthread_*() implementation
stores and calls the provided functions as-is, without checking for nullptr.
If the cursor Y position is < 0 in content coordinate space, we should
always map that to the first line of the file.
This fixes unexpected cursor behavior when dragging the selection above
the top of the document.
This removes some hard references to the toolchain, some unnecessary
uses of an external install command, and disables a -Werror flag (for
the time being) - only if run inside serenity.
With this, we can build and link the kernel :^)
This required a bit of rearchitecture, as pthread_atfork() required a
mutex, and duplicating a mutex impl for it was silly.
As such, this patch moves some standalone bits of pthread into LibC and
uses those to implement atfork().
It should be noted that for programs that don't use atfork(), this
mechanism only costs two atomic loads (as opposed to the normal mutex
lock+unlock) :^)
This implementation is pretty damn dumb, and probably has more bugs than
features.
But for the time being, it seems to work. however, we should definitely
replace it with a good implementation sometime very soon :^)
