The DrawingEngine didn't properly make a distinction between the
rectangle being filled and the damaged region on screen. This led to
unexpected results when using BAffineTransform.
- Destroy the background worker before going after all the managers. Otherwise,
there might potentially still be jobs in flight that might touch them, leading
to crashes.
The ScreenSaver window is now a BDirectWindow, but, _DrawFractals() makes
the assumption that a direct window means that the screen saver is running full
screen, so, we need to make sure we draw the preview using the
DrawBitmapAsync() method.
Fixes#10832
* data files are still in the source tree.
* gutenprint headers contain a image.h header file which collides
with ours. This is solved by forcing include search first on
os/kernel directory.
Due to introduction of user-defined suffixes C++11 requires that there
is a space between literal and identifier to avoid ambiguity.
This patch makes the whole kernel build successfully with C++11.
* This solves the issue where libreadline wasn't actually linked to libncurses
* x86_64 update will follow later, as the build maxed out my x86_64 build VM
This patch makes it possible to inline rdmsr and wrmsr instruction. The
performance impact shouldn't be significant since they are used relatively
rarely and wrmsr is usually a serializing instruction, but there is no reason
not to do so.
The goal of this patch is to amortize the cost of context switch by making
the compiler aware that context switch clobbers all registers. Because all
register need to be saved anyway there is no additional cost of using
callee saved register in the function that does the context switch.
Similarly to previous patch regarding GDT this is mostly a rewrite of
IDT handling code from C to C++. Thanks to constexpr IDT is now entirely
generated at compile-time.
Virtually no functional change, just rewriting the code from
"C in *.cpp files" to C++. Use of constexpr may be advantageous but
that code is not performance critical anyway.
CommitTransactionHandler: Since the VolumeState is now always copied
(including the contained packages), we can't just use the passed in
packagesAlready{Added,Removed} sets, since they refer to the original
packages.
