f70136a324 Kernel: Support open() with O_CREAT. 
It's now possible to create zero-length files! :^)
Also hook up the new functionality in /bin/touch.

a47f33bed3 WindowServer: Map shared GraphicsBitmaps read-only on the server side. 2019-01-21 19:27:23 +01:00
Andreas Kling
f9fcb682ec Keyboard: Use some of the existing defines instead of hard-coded numbers. 2019-01-21 07:30:46 +01:00
Andreas Kling
51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency. 
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.

aefbbeb3cb Flesh out keyboard event support a bit more. 2019-01-21 07:27:26 +01:00

76a2881793 Mark the two Regions used GraphicsBitmaps as explicitly shared. 
This fixes a goofy problem where forking a GUI process would cowify the
GraphicsBitmap for everyone making a hue confusing mess.

d1af5c97ca Kernel: Process should drop any framebuffer regions on exec(). 2019-01-21 03:22:03 +01:00
Andreas Kling
61e50780aa Kernel: Forked processes should inherit arguments and environment. 2019-01-21 02:59:58 +01:00
Andreas Kling
6127d33cee guitest2: Add a launcher button for guitest. 2019-01-21 02:56:25 +01:00
Andreas Kling
291922b1af WindowServer: Show PID and window ID in title bars for now. 
This is useful for debugging since I'm often wondering which process some
window belongs to (and what the window ID is.)
 2019-01-21 02:43:38 +01:00
Andreas Kling
e6fc84e234 Kernel: Make /proc/PID/fds display something useful for character devices. 2019-01-21 02:33:01 +01:00
Andreas Kling
786b903d62 WindowServer: Don't invalidate already frontmost window for moving to front. 2019-01-21 02:19:08 +01:00
Andreas Kling
e115ae5641 Kernel: Clone Process::m_gids on fork() and hook up any framebuffer region. 2019-01-21 01:49:30 +01:00

6d9959e367 LibGUI: Open the GUI event stream with O_CLOEXEC. 2019-01-21 01:33:16 +01:00

d66b0f7dd8 LibGUI: Mass coding style fixes. 2019-01-21 00:54:35 +01:00
Andreas Kling
6c4f1bad09 guitest2: Add a simple launcher so I can easily spawn more Terminals. 
Also update GButton coding style.

3271c115e2 WindowServer: Only blit dirty rect of windows to back buffer. 
Previously we'd blit every pixel in every window that intersected any dirty
rect to the back buffer. With this patch, we limit ourselves to blitting the
pixels inside the actual dirty rects.

There's still a lot of optimizations to make in this code.

1586bc99e3 WSWindowManager: Add an invalidation and a FIXME. 2019-01-20 08:37:24 +01:00
Andreas Kling
d4cce87dbc LibGUI: Minor fixes. 2019-01-20 08:16:02 +01:00
Andreas Kling
a9e60fc800 LibGUI: Only redraw the dirty rect in GWidget. 
There is some trouble here with the asynchronous nature of WindowServer
and the single per-window backing store we're drawing into. If we start
repainting a widget with a pending invalidation, that invalidation might
get flushed by the WindowServer mid-paint.

ea6678b7b3 LibGUI: Hook up GWindow event dispatch for paint and mouse events. 2019-01-20 07:03:38 +01:00
Andreas Kling
dbe83f3a83 Make it possible for userspace to alter window title/geometry. 
I'm not in love with this syscall API but it allows me to make progress.
 2019-01-20 06:04:13 +01:00
Andreas Kling
8eae89a405 Start bringing up LibGUI properly (formerly Widgets.) 2019-01-20 05:48:43 +01:00
Andreas Kling
b91479d9b9 Rename all the LibGUI classes to GClassName. 2019-01-20 04:49:48 +01:00
Andreas Kling
a026da47e7 Move Widget & friends into LibGUI. 2019-01-19 23:49:56 +01:00
Andreas Kling
7e5b81fe48 Make a SharedGraphics directory for classes shared between Kernel and LibGUI. 2019-01-19 23:22:46 +01:00

b413e234e1 WSWindowManager: Minor style fixes. 2019-01-19 14:33:59 +01:00
Andreas Kling
102a5add16 Invalidate the window when starting to drag it. 
This ensures that the drag color shows up immediately.
 2019-01-19 14:29:59 +01:00
Andreas Kling
4bffdd2394 WindowServer: Use a different border color for windows being dragged. 
Also get rid of an unnecessary invalidation on drag end.
 2019-01-18 15:55:28 +01:00
Andreas Kling
7e044cf293 Add a simple /bin/sysctl that wraps the files in /proc/sys. 2019-01-18 15:35:38 +01:00
Andreas Kling
f7cc454162 Add mechanism to expose kernel variables to userspace via ProcFS. 
Only booleans are supported at first. More types can be added easily.
Use this to add /proc/sys/wm_flash_flush which when enabled flashes pending
screen flush rects in yellow before they happen.

9454c5dd52 WindowServer: Merge WSFrameBuffer into WSScreen. 2019-01-18 05:41:15 +01:00
Andreas Kling
bb28c143fd Update coding style in WSWindowManager. 2019-01-18 05:33:35 +01:00

dff5051905 Support polling with select() by using a zero timeout. 
Use this in WindowServer to avoid getting blocked in select() when
there are pending injected events.
 2019-01-18 05:28:07 +01:00
Andreas Kling
a01e119e05 WindowServer: Always select() in the event loop. 
This fixes an issue where a steady stream of injected events would prevent
us from ever draining the mouse and keyboard inputs.
 2019-01-18 04:59:08 +01:00
Andreas Kling
dff70021ab Make it possible to invalidate only a portion of a window. 
Use this in Terminal to only invalidate rows where anything changed.
 2019-01-18 04:37:49 +01:00
Andreas Kling
9d7da26b4e StringBuilder: Use a ByteBuffer internally instead of a Vector<String>. 2019-01-18 03:27:51 +01:00
Andreas Kling
074edffc44 Add a simple StringBuilder::appendf() and use it for ProcFS. 
Okay, now ProcFS doesn't crash due to the crappy buffer size estimates
not really working out. This thing has dogshit performance and I will
fix that separately.
 2019-01-18 02:46:39 +01:00
Andreas Kling
dad58db757 Add WindowActivated and WindowDeactivated events. 
Use this to implement different looking Terminal cursors depending on
the window active state.
 2019-01-17 17:38:04 +01:00
Andreas Kling
135ff48bb9 Terminal: Tighten the glyph rects. 
This makes the cursor look a bit nicer.
 2019-01-17 16:34:37 +01:00
Andreas Kling
e9e57c5f65 Rename SpinLock to Lock. It hasn't been a SpinLock for some time. 
I'm pretty happy with the mechanism of AK::Lock for now.
 2019-01-17 16:25:02 +01:00
Andreas Kling
133f9aa352 WindowServer: Slap everything with locks. 2019-01-17 16:21:04 +01:00
Andreas Kling
5983a217c3 Terminal: Draw the terminal cursor. 2019-01-17 16:19:49 +01:00
Andreas Kling
3ad0ec9b1b Paper over annoying race in GraphicsBitmap instantiation. 
This works for now. This has to be done quite differently when I eventually
move the WindowServer to userspace.
 2019-01-17 02:58:34 +01:00
Andreas Kling
36e0ab3f18 Ignore WM_Invalidate events if there is an unprocessed one in the queue. 2019-01-17 02:42:52 +01:00
Andreas Kling
1c63a37bc9 Only drain mouse/keyboard streams if they actually have data. 
Technically we could just grab directly at the CharacterDevices like we've
been doing but I'd like to stay away from in-kernel behavior like that.
This should eventually become a userspace process.
 2019-01-17 02:34:08 +01:00
Andreas Kling
d793323254 Respect the overflow bit in PS/2 mouse data. 2019-01-17 02:32:40 +01:00
Andreas Kling
dc20f00872 PS2MouseDevice: Try to synchronize the data reporting stream. 
Turns out this was the reason QEMU wouldn't boot us.
 2019-01-17 02:13:21 +01:00

b5c76d7559 Get rid of #ifdef SERENITY. We're past that phase of bootstrapping. 2019-01-17 01:41:36 +01:00
