9860e55047 Kernel: Put page fault logspam behind PAGE_FAULT_DEBUG. 2019-02-10 11:37:59 +01:00
Andreas Kling
5e8d6b1bf4 Base: Rename /users to /home. 
I didn't like seeing /users next to /usr. /home looks nicer.

2def3d8d3f LibGUI: Start adding an automatic widget layout system. 
My needs are really quite simple, so I'm just going to add what I need
as I go along. The first thing I needed was a simple box layout with
widgets being able to say whether they prefer fixed or fill for both
their vertical and horizontal sizes.

I also made a simple GStatusBar so FileManager can show how many bytes
worth of files are in the current directory.

4a7120afe1 SharedGraphics: Fix blitting GraphicsBitmaps with clipping enabled. 2019-02-10 07:46:29 +01:00

f7831f8c76 LibGUI: Draw GScrollBar buttons with a disabled look when appropriate. 2019-02-10 07:37:02 +01:00

1e8e4e9af2 Launcher: Add button for FileManager. 2019-02-10 07:36:37 +01:00
Andreas Kling
e354c08c98 LibGUI: Share code for widget rendering styles in a GStyle class. 
Since GScrollBar wants its internal buttons to look like GButtons,
let's share the painting code between them.

9ea2131adf LibGUI: Support dragging the GScrollBar scrubber. 
This was pleasantly easy to implement with the global mouse tracking. :^)
 2019-02-10 06:51:01 +01:00

6b8af2f33a Base: Improved FontEditor icon. 2019-02-10 06:30:16 +01:00

cc04ba9cc9 ProcFS: /proc/sys entries should always be regular 644 files. 2019-02-10 06:10:01 +01:00
Andreas Kling
5bd363c4bb LibGUI: Widget updates should invalidate their window-relative rect. 2019-02-09 14:30:05 +01:00
Andreas Kling
6a3ff7efc5 GScrollBar: Start looking a bit more like a proper scrollbar. 
And hook up FileManager's DirectoryView with its scrollbar so it actually
causes the directory view to shift up and down. Very cool. :^)
 2019-02-09 11:29:59 +01:00

1f355f2a79 LibGUI: Start working on a GScrollBar. 
This widget is far from finished, but it's off to a good start.
Also added a GResizeEvent and GWidget::resize_event() so that widgets
can react to being resized.
 2019-02-09 11:19:38 +01:00

4d5fe39494 FileManager: Start building a file manager. 2019-02-09 09:22:04 +01:00
Andreas Kling
8ae7be611a LibC: closedir() should free the readdir() buffer and the DIR itself. 2019-02-09 09:08:27 +01:00
Andreas Kling
c4e984ca49 Kernel: Allow mmap() with a size that's not a multiple of page size. 
We just round it up to the next multiple of page size anyway.
 2019-02-09 08:44:46 +01:00

fa241747af Kernel: When donating ticks to a lock holder, cap the donation. 
When donating ticks to a lock holder, never donate more ticks than
that process would normally get from the scheduler.
 2019-02-08 22:06:30 +01:00

cb6e852620 SharedGraphics: Don't eagerly commit mmap'ed font files in kernel. 
Just let the page fault handler do its thing. Anytime we can avoid
loading some pages from disk, that's a good thing.
 2019-02-08 21:59:06 +01:00

b365ad4aef LibC: fgetc() and pals should return EOF on error or EOF. 
This was the reason that "uname | figlet" wasn't working. There was nothing
wrong with the pipe like I kept thinking.
 2019-02-08 17:49:54 +01:00

c9aaf74e1d LibC: Add some more fake termcap entries to silence bash-5.0. 2019-02-08 17:49:25 +01:00

6274208eb9 Ext2FS: Fix bitmap overrun when reaching outside the first block group. 2019-02-08 17:14:51 +01:00
Andreas Kling
a6f9ddbb58 Let's have two wallpapers installed so we can test switching. 2019-02-08 17:14:47 +01:00
Andreas Kling
cf58b76210 SharedGraphics: GraphicsBitmap::load_from_file() should be allowed to fail. 
It's okay if it fails to load a bitmap in kernel space. Just return nullptr.
 2019-02-08 16:49:05 +01:00

d4ba155711 Kernel: Break retain cycle between Inode and VMObject. 
There's no need for an Inode to keep its corresponding VMObject alive.
Obviously there are huge benefits to keeping a filesystem cache,
but leaking everything is hardly the right strategy. :^)
 2019-02-08 16:40:48 +01:00

e1be5a468d Userland: Add a /bin/pape helper program to switch the desktop wallpaper. 2019-02-08 16:22:54 +01:00
Andreas Kling
33d34d9b26 Kernel: Use a Lockable<bool> for sysctl booleans as well. 2019-02-08 16:18:24 +01:00
Andreas Kling
e78e032c19 Add a little ReadMe. 2019-02-08 11:06:34 +01:00

f8fc892bac Remove _fs_contents.stock and generate it on the fly instead. 2019-02-08 09:56:39 +01:00
Andreas Kling
7a996e608c WindowServer: Allow changing the desktop wallpaper through a sysctl. 
Just write the path of your new wallpaper to /proc/sys/wm_wallpaper. :^)
 2019-02-08 09:49:09 +01:00

cda598c29c SharedGraphics: Allocate file-backed kernel GraphcisBitmaps in WindowServer. 2019-02-08 09:48:28 +01:00
Andreas Kling
004aad0995 WindowServer: Set the WSMessageLoop::server_process() as early as possible. 2019-02-08 09:47:57 +01:00
Andreas Kling
a3799cb71e ProcFS: Add sysctl strings. 
They are backed by a Lockable<String> to ensure that access is synchronized.
 2019-02-08 09:46:46 +01:00

dabb3c902a AK: Add a Lockable wrapping container. 2019-02-08 09:46:13 +01:00

7e623e7ff2 Process: Dump regions when a ring0 process crashes. 2019-02-08 09:45:53 +01:00
Andreas Kling
90d3375dc2 WindowServer: Support desktop wallpapers. 
For now, you don't get to choose the wallpaper, but it's still pretty cool.
 2019-02-08 08:45:59 +01:00

2736957701 Ext2FS: Fix dumb bitmap size bug in *_inode_allocation_state(). 2019-02-08 08:43:08 +01:00
Andreas Kling
736e852525 LibC: Implement enough missing stuff to get bash-5.0 running. :^) 2019-02-08 02:38:21 +01:00
Andreas Kling
5158bee08c Don't use -mregparm=3 in userspace. 
It's pretty comfy having arguments in registers in the kernel for now though.
 2019-02-08 01:24:52 +01:00

04378d9063 Terminal: Use the same cursor rect for active/inactive windows. 2019-02-08 00:21:02 +01:00
Andreas Kling
6d7f000ffc Launcher: Factor the app buttons into a LaunchButton class. 
Added some LibGUI helpers while I'm at it.
 2019-02-08 00:15:04 +01:00

bf766fc12c LibGUI: Implement GWindow::rect(). 2019-02-08 00:13:35 +01:00

2ac697ca09 LibC: execl() forgot to add the null sentinel to argv. 2019-02-08 00:12:35 +01:00
Andreas Kling
f4bce03716 Kernel: When validating a string read, validate the pointer first. 
Calling strlen() on an invalid pointer is just gonna crash the process.
 2019-02-08 00:10:01 +01:00
Andreas Kling
887b4a7a1a Start working on a simple Launcher app. 
Let GButton have an optional icon (GraphicsBitmap) that gets rendered in the
middle of the button if present.

Also add GraphicsBitmap::load_from_file() which allows mmap'ed RGBA32 files.
I wrote a little program to take "raw" files from GIMP and swizzle them into
the correct byte order.

71b9ec1ae0 Kernel: Add basic process priority support. 
For now, the WindowServer process will run with high priority,
while the Finalizer process will run with low priority.
Everyone else gets to be "normal".

At the moment, priority simply determines the size of your time slices.
 2019-02-07 12:21:17 +01:00
Andreas Kling
ee2bb98b88 Kernel: Increase default time slice to 20ms. 2019-02-07 11:53:45 +01:00
