4b15dd2bca LibGUI: Rename GEventLoop::exit() and GApplication::exit() to quit(). 
These functions don't exit immediately, but rather on the next iteration
of the event loop.

Since exit() is already used by the standard library, let's call it quit()
instead. That way, saying exit() means the same thing here as anywhere else.

fa452fadca WindowServer: Let menu objects reference the WSClientConnection by pointer. 
Since these are owner/ownee relationships, there's no need for indirection.

9a39c01551 WindowServer: WSWindow can have a pointer to the client rather than an ID. 
Since WSWindows are owned by WSConnectionClients, it's fine for them to just
reference the client directly.

2dc0ef8813 Kernel: munmap() should round up to nearest page size, just like mmap(). 
The mismatch between the two was causing some trouble if you'd mmap e.g 1KB
and then try to munmap() it. The kernel would whine that it couldn't find
any such mapping (because mmap() actually rounded the 1KB to a 4KB page.)

809266a9fb Kernel: Remove tracking of bitmap memory. 
There are no more kernel bitmaps. It's much better this way.

3eb6c22a22 WindowServer: Make the menubar clock work again in the post-kernel world. 
This is actually so much better. Grabbing directly at the RTC was silly. :^)

9b2b9fe39b SharedGraphics: Fix #ifdef mismatch in Painter. 
This mistake created an incredible amount of confusion. We would allocate
a slightly too small Painter on the stack and then invoke its constructor,
overwriting whatever came after it on the stack.

640360e958 Move WindowServer to userspace. 
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)

09aaa41e62 SharedGraphics: Rework GraphicsBitmap::create_kernel_only() into create(). 
And just use mmap() to allocate the pixels.

4ea28bf0a5 Kernel: Add a simple shared memory API for two processes only. 
And use this to implement shared bitmaps between WindowServer and clients.

4db78dabd3 Kernel: Rename create_framebuffer_wrapper() to create_for_physical_range(). 
Maybe there will be other types of physical ranges to map in the future.
This API doesn't seem at all specific to framebuffers.
Also tidy up a bit in BochsVGADevice.

468113422f Kernel: Add ioctls to BochsVGADevice for mode setting and page flipping. 
Use these in WindowServer instead of poking at the BochsVGADevice directly.
 2019-02-16 10:26:01 +01:00
Andreas Kling
799177feda Kernel: Make BochsVGADevice a BlockDevice and support mmapping it. 
Currently you can only mmap the entire framebuffer.
Using this when starting up the WindowServer gets us yet another step
closer towards it moving into userspace. :^)

749db8237c Ext2FS: Fix various bugs in inode and block allocation. 
I had the wrong idea about how group indices work, so using a larger fs
with more than one group caused all kinds of mess.

cbfd416279 LibC: The standard C library needs to be able to build as pure C. 
Looks like we can't use those comfy C++ attributes in this code then.

022f7790db Use modern C++ attributes instead of __attribute__ voodoo. 
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

fbcc8ab840 WindowServer: Slurp all available client messages when checking them. 
We were reading one client message per client per event loop iteration.
That was not very snappy. Make the sockets non-blocking and read() until
there are no messages left.

It would be even better to make as few calls to read() as possible to
reduce context switching, but this is already a huge improvement.

18210c606d Kernel: Remove GUIEventDevice. 
It's no longer used since all communication now happens across sockets. :^)

ce74db4e2a Userland: /bin/ls should display socket files nicely. 2019-02-14 17:30:58 +01:00

bf58241c11 Port the WindowServer and LibGUI to communicate through local sockets. 
This is really cool! :^)

Apps currently refuse to start if the WindowServer isn't listening on the
socket in /wsportal. This makes sense, but I guess it would also be nice
to have some sort of "wait for server on startup" mode.

This has performance issues, and I'll work on those, but this stuff seems
to actually work and I'm very happy with that.

00319c248c Kernel: Let's say that listening+bound sockets "can read." 
This will make it easy-peasy to select() on a socket file descriptor to wait
for incoming connections together with other activities.
