7aba0058ae sync.sh: Don't regenerate _fs_contents from /dev/zero every time. 
This makes sync.sh run a lot faster, especially on slower machines.

1bf37db9a9 Ext2FS: Simplify block bitmap stuff. 
Block bitmaps are only ever one block in size. I don't know why I thought
otherwise, but use this info to simplify the code. :^)

58240fdb33 Do a pass of compiler warning fixes. 
This is really making me question not using 64-bit integers more.

e24e486714 Snake: Flesh out a basic snake game :^) 2019-04-20 03:24:50 +02:00
Andreas Kling
3817f5f619 Kernel+LibC: Add a DebugLogDevice that forwards everything to I/O port 0xe9. 
This is then used to implement the userspace dbgprintf() in a far more
efficient way than what we had before. :^)

024057b39a Userland: Make sync.sh copy all executables from ../Userland 2019-04-15 13:53:27 +02:00
Andreas Kling
c0fe48635b Kernel: Add /proc/uptime file (number of seconds since boot.) 
Also added a simple /bin/uptime to pretty-print this information. :^)

a90e218c71 Minesweeper: Start working on a simple minesweeper game. :^) 2019-04-13 03:08:16 +02:00
Andreas Kling
8268ece1bd VisualBuilder: Start working on an interface builder application. 
It's tedious making interfaces programmatically. Let's make a program to
help us with this. :^)
 2019-04-11 00:05:47 +02:00
Andreas Kling
37ae00a4dd Kernel+Userland: Add the rename() syscall along with a basic /bin/mv. 2019-04-07 23:35:26 +02:00
Andreas Kling
8f30657390 Start working on a Downloader app and backing classes in LibGUI. 
LibGUI is slowly becoming LibKitchensink but I'm okay with this for now.

9fbac66a91 Hack sync.sh script to retry umount after a short delay if it fails. 
I keep accumulated unwanted mounts because umount sometimes fails.
 2019-04-05 16:26:29 +02:00
Andreas Kling
a22774ee3f Taskbar: Start working on a taskbar app. 
I originally thought I would do this inside WindowServer, but let's try to
make it as a standalone app that communicates with WindowServer instead.
That will allow us to use LibGUI. :^)

f9864940eb Kernel: Move FS-related files into Kernel/FileSystem/ 2019-04-03 12:25:24 +02:00
Andreas Kling
e561ab1b0b Kernel+LibC: Add a simple create_thread() syscall. 
It takes two parameters, a function pointer for the entry function,
and a void* argument to be passed to that function on the new thread.
 2019-03-23 22:59:08 +01:00
Andreas Kling
42755e98cf SharedGraphics: Implement a simple PNG decoder. 
This is extremely unoptimized, but it does successfully load "folder32.png"
so it must be at least somewhat correct. :^)

d17a91f185 Move WindowServer into Servers. 2019-03-20 04:34:14 +01:00

9120b05a40 Rename DNSLookupServer => LookupServer. 2019-03-20 04:26:30 +01:00
Andreas Kling
0e4a1936ca LibC: Implement gethostbyname() by talking to the DNSLookupServer. 
We now talk to the lookup server over a local socket and it does the lookup
on our behalf. Including some retry logic, which is nice, because it seems
like DNS requests disappear in the ether pretty damn often where I am.
 2019-03-20 01:15:22 +01:00
Andreas Kling
fe2fa4ac80 DNSLookupServer: Start working on a userspace DNS resolver. 
This doesn't have any server functionality just yet, but it does post
decent-looking DNS queries and parse the responses.
 2019-03-19 16:29:06 +01:00
Andreas Kling
aa19735c5a IRCClient: Start working on a simple graphical IRC client. 
This will be a nice way to exercise both LibGUI and the TCP/IP support. :^)
 2019-03-15 12:14:23 +01:00
Andreas Kling
7aba68d51c Userland+LibC: Add a new little "tc" program for testing TCP. 
Also added send() and recv() to LibC in support of this. They are just
wrappers around sendto() and recvfrom().
 2019-03-13 17:33:40 +01:00
Andreas Kling
ea6a537b70 Userland: Add a simple utility for UDP testing. 2019-03-13 15:00:02 +01:00
Andreas Kling
a017a77442 Kernel+LibC+Userland: Start working on an IPv4 socket backend. 
The first userland networking program will be "ping" :^)
 2019-03-12 15:51:42 +01:00
Andreas Kling
9158de6c41 Begin working on a graphical TextEditor. 
It's gonna be a wrapper around a new GTextEditor widget so I can easily
reuse the functionality anywhere I need it. :^)
 2019-03-07 00:31:06 +01:00
Andreas Kling
166aadc4e1 ProcessManager: Start working on a graphical process manager. 
I need a table view widget for this thing, so I'm also using this to
prototype a model/view thingy.

dda9b9ab1b Userland: Add a simple /bin/stat program. 2019-02-27 21:45:06 +01:00
Andreas Kling
1d2529b4a1 Add chown() syscall and a simple /bin/chown program. 2019-02-27 12:32:53 +01:00
Andreas Kling
a7a456002e LibC: Enough compat work to make binutils-2.32 build and run. 2019-02-23 17:24:50 +01:00

afa6f88039 Throw away the Clock app since we now have a clock in the menubar. :^) 2019-02-22 10:42:29 +01:00
Andreas Kling
6d3e12899b Kernel: Pass process arguments directly on the stack. 
Get rid of the convoluted get_arguments and get_environment syscalls.
This patch also adds a simple /bin/env that just prints its environment.
 2019-02-22 01:55:22 +01:00
Andreas Kling
920e8e58ed Kernel+Userland: Implement setuid() and setgid() and add /bin/su 
Also show setuid and setgid bits in "ls -l" output. :^)
 2019-02-21 23:38:10 +01:00
Andreas Kling
f5f136931a Kernel: Start adding various file system permission checks. 
Fail with EACCES in various situations. Fix userland bugs that were exposed.
 2019-02-21 15:45:31 +01:00
Andreas Kling
43075e5878 Add a simple /bin/df which gathers its info from /proc/df. 2019-02-21 14:48:00 +01:00
Andreas Kling
7d288aafb2 Kernel: Add link() syscall to create hard links. 
This accidentally grew into a little bit of VFS cleanup as well.

Also add a simple /bin/ln implementation to exercise it.

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 :^)
 2019-02-17 00:13:47 +01:00

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. :^)
 2019-02-16 09:57:42 +01:00
Andreas Kling
18210c606d Kernel: Remove GUIEventDevice. 
It's no longer used since all communication now happens across sockets. :^)
 2019-02-15 08:59:55 +01:00
Andreas Kling
f529b845ec WindowServer: Convert entire API to be message-based. 
One big step towards userspace WindowServer. :^)

d74b131c27 Add a little About app and hook it up to the system menu's "About..." entry. 
Added icons and customizable text alignment to GLabel.

6b2d2cc5e3 Create /dev files for null, full, zero and random. 2019-02-11 06:59:28 +01:00
Andreas Kling
5e8d6b1bf4 Base: Rename /users to /home. 
I didn't like seeing /users next to /usr. /home looks nicer.
 2019-02-10 11:18:12 +01:00
Andreas Kling
2cf1dd5b6f Move apps into a top-level Applications/ directory. 2019-02-10 08:35:01 +01:00

a6f9ddbb58 Let's have two wallpapers installed so we can test switching. 2019-02-08 17:14:47 +01:00
Andreas Kling
e1be5a468d Userland: Add a /bin/pape helper program to switch the desktop wallpaper. 2019-02-08 16:22:54 +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
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.

d0078b6574 Clock: Turns the clock window from guitest2 into a separate program. 
We can't not have a desktop clock app. :^)
 2019-02-05 09:44:13 +01:00
Andreas Kling
c0cffe1134 Add a /bin/top program for process table monitoring. 
It automagically computes %CPU usage based on the number of times a process
has been scheduled between samples. The colonel task is used as idle timer.
This is pretty cool. :^)
