A Lock can now be held either in shared or exclusive mode. Multiple threads can
hold the same lock in shared mode at one time, but if any thread holds the lock
in exclusive mode, no other thread can hold it at the same time in either mode.
The next commit is going to make it bigger again by increasing the size of Lock,
so make use of bitfields to make sure FileDescription still fits into 64 bytes,
and so can still be allocated with the SlabAllocator.
I noticed these when playing with the demo locally:
- Use RGB32 instead of RGBA32 for the bitmap buffer. This avoids some
flickering that would sometimes occur.
- Clip the gradient fill to the widget rect rather than the painter
clip rect. In practice, the painter was always clipped to the widget
rect here, but it seems logical to say "fill widget with gradient."
Everyone who constructs an Object must now pass a prototype object when
applicable. There's still a fair amount of code that passes something
fetched from the Interpreter, but this brings us closer to being able
to detach prototypes from Interpreter eventually.
Let's start moving towards native JS objects taking their prototype as
a constructor argument.
This will eventually allow us to move prototypes off of Interpreter and
into GlobalObject.
This commit implements the getprotoent() family of functions, including
getprotoent()
getprotobyname()
getprotobynumber()
setprotoent()
endprotoent()
This implementation is very similar to the getservent family of functions,
which is what led to the discovery of a bug in the process of reading the aliases.
The ByteBuffer for the alias strings didn't include a null terminating character,
this was fixed for both the protoent and servent family of functions by appending a
null character to the end of them before adding them to the alias lists.
`PSClientConnection::did_finish_download()` no longer tries to create
a zero byte shared buffer when `download.payload().data()` is zero
bytes in length.
Fixes#1821
This patch adds the following methods to CanvasRenderingContext2D:
- beginPath()
- moveTo(x, y)
- lineTo(x, y)
- closePath()
- stroke()
We also add the lineWidth property. :^)
This will be used to implement painting of 2D paths. This first patch
adds support for line_to(), move_to() and close().
It will try to have the same semantics as the HTML <canvas> element.
To stroke a Path, simply pass it to Painter::stroke_path().
We don't need a wrapper Function object that just forwards the timer
callback to the scheduler tick function. It already has the same
signature, so we can just plug it in directly. :^)
Same with the clock updating function.
