6cabd34b93 Userland: Improve head program 
* allow specifying files as arguments, e.g. `head a b c`
* support multiple files
* print a filename header when multiple files are being printed
* allow suppression or forcing of filename header via flags

This change drops support for the legacy `-123` syntax in favour of the
more widely-supported `-n 123` form.

Currently supported crash types:

    -s : Segmentation violation
    -d : Division by zero

677794f30d LibGUI: Make GCheckBox inherit from GAbstractButton. 2019-05-24 17:11:42 +02:00
Andreas Kling
21c56477b0 LibGUI: Add a GAbstractButton base class for button widgets. 
This patch moves GButton and GRadioButton to inherit from it. This allows
them to share code for mouse event handling, etc.

77dfd419e9 LibCore: Move AK/ArgsParser to LibCore/CArgsParser 
Also rename the classes to match LibCore naming style.
This means that it's no longer incorrectly linked into LibC and Kernel.

bffed9e3cb ArgsParser: Expand to be able to handle multiple single arguments 
This is needed for e.g. ln

Robin Burchell
6dd7ee53ea AK/Userland: Add single value to ArgsParser usage, and port tail to use ArgsParser 2019-05-17 15:49:37 +02:00
Robin Burchell
c478503581 ArgsParser: Remove prefix from constructor 
It makes sense to keep this consistent between applications, and the
purpose of the string is not immediately obvious from an API perspective.

If we need to make it configurable later, that can come from a setter.
 2019-05-17 15:49:37 +02:00
Robin Burchell
729507f2bd ArgsParser: Remove boolean trap on add_arg 
Rather than requiring a boolean for whether or not the argument is
required, add some new methods to make the purpose of the bool explicit.
 2019-05-17 15:49:37 +02:00
Robin Burchell
c8fda23a03 LibCore/Userland: Introduce a simple tail implementation 
Also introduce more seek modes on CIODevice, and an out param to find
the current position inside the file -- this means less syscalls (and
less potential races) than requesting it through a separate pos()
accessor or something.

8b249bd09b Kernel+Userland: Implement mknod() syscall and add a /bin/mknod program. 2019-05-03 22:59:58 +02:00
Andreas Kling
2a65f0ee4f strace: Allow "strace command" to trace a process from start to finish. 
Tracing a specific pid is now done via "strace -p PID".
To ensure we don't miss any syscalls, we fork and have the child immediately
SIGSTOP itself. Then when the parent has set up the systrace() fd, we send
SIGCONT to the child which then execs the command. :^)
 2019-05-02 15:51:39 +02:00

Andreas Kling
96d4b701e6 sh: Make "cd" jump to the home directory. And also let's set $HOME. 
Nobody else is setting $HOME right now, so we might as well do it here.
This should eventually be done by some sort of "login" program.
 2019-04-25 23:09:21 +02:00
Andreas Kling
89e9aafbb5 sh: Support erasing a whole word with WERASE (^W). 2019-04-25 23:05:10 +02:00
Andreas Kling
04b7def6ab sh: Add support for redirecting stdin and stdout with < and >. 
This is certainly about time. The kernel has had all the necessary support
in place for months, and I just kept postponing working on the shell. :^)
 2019-04-25 16:10:16 +02:00
Andreas Kling
df8e76a67c cat: Just use fd 0 when no arguments are passed. 
I'm not sure why it seemed necessary at some point to open /dev/stdin rather
than simply using the already-open fd 0.
 2019-04-25 16:01:28 +02:00

91f561a417 touch: Newly created files were accidentally marked as FIFO's. 2019-04-23 17:04:12 +02:00
Andreas Kling
5c68929aa1 Kernel: Add a systrace() syscall and implement /bin/strace using it. 
Calling systrace(pid) gives you a file descriptor with a stream of the
syscalls made by a peer process. The process must be owned by the same
UID who calls systrace(). :^)

57da00b731 Include Makefile.common in all other Makefiles. 2019-04-21 04:09:39 +02:00

5f63f8120c Kernel: Remove "restorer" field from SignalActionData. 
I was originally implementing signals by looking at some man page about
sigaction() to see how it works. It seems like the restorer thingy is
system-specific and not required by POSIX, so let's get rid of it.

5eedb22834 Sprinkle use of AK::Vector in various places. 
Some of these are less helpful than others. Avoiding a bunch of mallocs
in the event loop wakeup code is definitely nice.

301a269ca0 Get rid of SERENITY macro since the compiler already defines __serenity__ 
This makes it a bit easier to use AK templates out-of-tree.

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

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

aef6030a80 LibC: Time-related POSIX compliance fixes. 2019-03-27 01:31:53 +01:00

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.

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
Andreas Kling
3f29a12d90 More compat work. Rename libraries from LibFoo.a => libfoo.a 
This makes it more straightforward to build a cross-compiler toolchain.
Also move math stuff from LibC to LibM.
 2019-02-26 13:30:57 +01:00
Andreas Kling
9624b54703 More moving towards using signed types. 
I'm still feeling this out, but I am starting to like the general idea.

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.

920e8e58ed Kernel+Userland: Implement setuid() and setgid() and add /bin/su 
Also show setuid and setgid bits in "ls -l" output. :^)

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.

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

f529b845ec WindowServer: Convert entire API to be message-based. 
One big step towards userspace WindowServer. :^)
 2019-02-14 01:21:32 +01:00
Andreas Kling
fbbf57b61c Rename GUI_Event to GUI_ServerMessage. 
Now that communication is becoming bidirectional, "event" is no longer right.

5158bee08c Don't use -mregparm=3 in userspace. 
It's pretty comfy having arguments in registers in the kernel for now though.

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.

5582a0a254 Kernel: When a lock is busy, donate remaining process ticks to lock holder. 
Since we know who's holding the lock, and we're gonna have to yield anyway,
we can just ask the scheduler to donate any remaining ticks to that process.

27263b6172 Clean up LDFLAGS a bit. 
While working on the ELF loader I was trying to keep binaries as simple as
possible so I could understand them easily. Now that the ELF loader is mature
and working fine, we can move closer towards ld defaults.

3accdb0e93 Handle WindowCloseRequest in FontEditor and /bin/guitest. 2019-02-05 12:07:06 +01:00
Andreas Kling
11db8c1697 Add a simple close button ("X") to windows. 
Clicking the button generates a WindowCloseRequest event which the client app
then has to deal with. The default behavior for GWindow is to close() itself.

I also added a flag, GWindow::should_exit_event_loop_on_close() which does
what it sounds like it does.

This patch exposed some bugs in GWindow and GWidget teardown.

d0078b6574 Clock: Turns the clock window from guitest2 into a separate program. 
We can't not have a desktop clock app. :^)

41567c5bb9 Show the amount of memory in GraphicsBitmaps in /bin/top.

b1e054ffe8 Rename LizaBold to LizaRegular and LizaBlack to LizaBold. 
LizaRegular is quickly becoming my favorite bitmap font. It's so pretty :^)

d7307c3119 Kernel: Ignore SIGCHLD by default. 
Also use an enum for the rather-confusing return value in dispatch_signal().
I will go through the rest of the signals and set them up with the
appropriate default dispositions at some other point.
 2019-02-04 14:06:38 +01:00

ba6ffea03c Kernel: Process should send SIGCHLD to its parent when it dies. 2019-02-04 13:30:03 +01:00

7fe600f250 LibGUI: Use LightGray as the base UI color. 
This feels nicely reminiscent of the gap in time between Win3.11 and Win95,
one of my favorite eras in UI look-and-feel.
