VAN BOSSUYT Nicolas 12f2d1f2e8 Uptime: making the ouput prettier

 2019-04-14 19:10:24 +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. :^)
 2019-04-14 15:19:45 +02:00
Andreas Kling 5e0577a042 Introduce LibCore and move GElapsedTimer => CElapsedTimer. 
I need a layer somewhere between AK (usable both by userspace and kernel)
and LibGUI (usable by userspace except WindowServer.) So here's LibCore.
 2019-04-10 16:14:44 +02:00
Andreas Kling 4ab0cd5d4c LibGUI: Move frame painting from GFrame to StylePainter. 
This way it can be used by others who might not have a GFrame object.
 2019-04-10 03:43:46 +02:00
Andreas Kling 313ac51832 LibGUI: Turn GTextBox into a wrapper around a single-line GTextEditor. 2019-04-10 03:08:29 +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 5d72cf5a3f LibGUI: Improve GFrame's look for Container shapes. 
This is now starting to look like a proper container. Very nice :^)
 2019-03-28 20:15:13 +01:00
Andreas Kling f939fb7eb7 Userland: Add a simple GFrame testing window to guitest2. 2019-03-28 18:52:03 +01:00
Andreas Kling 9fa21fa585 LibGUI: Add a GPainter class that inherits from Painter. 
This gets rid of the last little piece of LibGUI knowledge in Painter.
 2019-03-28 17:19:56 +01:00
Andreas Kling 0058da734e Kernel: Add Inode::truncate(size). 
- Use this to implement the O_TRUNC open flag.
- Fix creat() to pass O_CREAT | O_TRUNC | O_WRONLY.
- Make sure we truncate wherever appropriate.
 2019-03-27 16:42:30 +01:00
Andreas Kling 23bb276fcd LibC: Run constructors on process startup. 
Cooperate with the compiler to generate and execute the _init_array list
of constructor functions on userspace program statup. This took two days
to get working, my goodness. :^)
 2019-03-27 12:48:21 +01:00
Andreas Kling aef6030a80 LibC: Time-related POSIX compliance fixes. 2019-03-27 01:31:53 +01:00
Andreas Kling 7e54fdce99 QuickShow: Fill the window with white if the opened image has alpha. 2019-03-24 03:07:00 +01:00
Andreas Kling d563dc0565 LibGUI: Add a setting to make GLabel stretch its icon. 
Use this in QuickShow to allow arbitrarily scaling the opened image.
 2019-03-22 04:20:48 +01:00
Andreas Kling c3b0c1ba68 LibGUI: Add a GProgressBar widget. 2019-03-22 02:49:45 +01:00
Andreas Kling e4dfd5a3a4 WindowServer: Support PNG wallpapers. 
Fix up /bin/pape so it tells the WindowServer which wallpaper file to use.
 2019-03-21 15:54:19 +01:00
Andreas Kling 0114c61cf1 Userland: Turn off double buffering in QuickShow. 
Since this program is primarily used to display potentially huge but still
static images, let's not put extra strain on the system by double buffering.
 2019-03-21 13:31:47 +01:00
Andreas Kling 65348e7dc1 PNGLoader: Support for color type 2 (RGB triplets) and multiple IDAT chunks. 2019-03-21 05:25:54 +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. :^)
 2019-03-21 03:57:42 +01:00
Andreas Kling 4ea625e08b Userland: Allow ping <hostname> :^) 2019-03-20 03:38:09 +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 57ff293a51 LibGUI: Implement nested event loops to support dialog boxes. 
This patch adds a simple GMessageBox that can run in a nested event loop.
Here's how you use it:

    GMessageBox box("Message text here", "Message window title");
    int result = box.exec();

The next step is to make the WindowServer respect the modality flag of
these windows and prevent interaction with other windows in the same
process until the modal window has been closed.
 2019-03-19 00:01:02 +01:00
Andreas Kling 4629272135 Userland: Turn the tc test util into a simple dumb HTTP client. 2019-03-14 15:19:20 +01:00
Andreas Kling 3d5296a901 IPv4: Last burst of TCP hacking for today. 
Connecting to a test server and exchanging data back and forth works.
 2019-03-14 01:44:42 +01:00
Andreas Kling be46f1bb1f IPv4: More work on the TCP implementation. 
Reading from the peer now kinda works. Something still going wrong with
sending packets but it's getting closer.
 2019-03-14 01:00:10 +01:00
Andreas Kling 032d9d7065 IPv4: More hacking on bringing up TCP support. 
This was a bit more complicated than I expected, but it's moving forward.
 2019-03-13 23:14:30 +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 4dddf949c8 IPv4: More work on UDP support. 
I'm now able to connect to a simple UDP server on my host machine and
exchange some data. Very cool! :^)
 2019-03-13 15:40:30 +01:00
Andreas Kling ea6a537b70 Userland: Add a simple utility for UDP testing. 2019-03-13 15:00:02 +01:00
Andreas Kling 19a51132f5 Kernel: recvfrom() should treat the address arguments as outparams. 2019-03-13 14:47:21 +01:00
Andreas Kling 562663df7c Add support for socket send/receive timeouts. 
Only the receive timeout is hooked up yet. You can change the timeout by
calling setsockopt(..., SOL_SOCKET, SO_RCVTIMEO, ...).

Use this mechanism to make /bin/ping report timeouts.
 2019-03-13 13:15:05 +01:00
Andreas Kling cf250e1245 More work on IPv4 sockets and /bin/ping. 
It's now actually possible to ping other hosts on the network! :^)
I've switched the "run" script over to starting QEMU with user networking
since that works better for my testing needs right now.
 2019-03-13 03:26:01 +01:00
Andreas Kling a7d5e9781a Kernel+LibC+Userland: Yet more networking bringup hacking. 
All ICMP sockets now receive all ICMP packets. All this buffering is gonna
need some limits and such.
 2019-03-12 17:27:07 +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 971dd46aec Userland: Use AK::quick_sort() in /bin/top 2019-03-09 16:20:46 +01:00
Andreas Kling 28a6ba498a Userland: Fix broken permissions for files created by /bin/cp. 
When passing O_CREAT to open(), it will grab a third "mode" argument from
the stack. Let's not forget to actually pass this!

Also use the process umask for the created files.
 2019-03-07 23:23:07 +01:00
Andreas Kling 3079ef01ce Userland: /bin/cp needs to handle open(dst) failing with EISDIR. 2019-03-06 20:28:00 +01:00
Andreas Kling 7d46375690 Userland: Support "cp foo somedirectory" 
Don't overwrite the literal directory inode contents when copying a file
to a directory, duh. :^)
 2019-03-06 20:22:23 +01:00
Andreas Kling 66a5ddd94a More work on the variable-width font support. 
Katica is now the default system font, and it looks quite nice. :^)
I'm gonna need to refine the GTextBox movement stuff eventually,
but it works well-enough for basic editing now.
 2019-03-06 14:06:40 +01:00
Andreas Kling 2c5a378ccc Kernel+Userland: Add symlink() syscall and add "-s" flag to /bin/ln. 
It's now possible to create symbolic links! :^)

This exposed an issue in Ext2FS where we'd write uninitialized data past
the end of an inode's content. Fix this by zeroing out the tail end of
the last block in a file.
 2019-03-02 01:52:24 +01:00
Andreas Kling 1b16a29044 Kernel+Userland: Implement fchmod() syscall and use it to improve /bin/cp. 
/bin/cp will now copy the permission bits from source to destination. :^)
 2019-03-01 10:39:19 +01:00
Andreas Kling c09ab7cc40 Kernel: Only allow sending signals to process you own. 2019-02-28 11:46:38 +01:00
Andreas Kling dda9b9ab1b Userland: Add a simple /bin/stat program. 2019-02-27 21:45:06 +01:00
Andreas Kling 02bfbb712a Userland: /bin/ls should show major,minor for block devices. 2019-02-27 21:32:21 +01:00
Andreas Kling 1d2529b4a1 Add chown() syscall and a simple /bin/chown program. 2019-02-27 12:32:53 +01:00
