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. :^)

6071a77e8e Userland: Remove the /bin/sh greeting. It was cute but spammy. 2019-02-21 23:34:14 +01:00

43075e5878 Add a simple /bin/df which gathers its info from /proc/df. 2019-02-21 14:48:00 +01:00

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. :^)

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.
This seems like an extremely relevant metric to track.

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.

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.

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. :^)

31f44481f3 Add /dev/{stdin,stdout,stderr} as symlinks to /proc/self/fd/{0,1,2}
Also change /bin/cat to open /dev/stdin if no arguments are provided.

c2adfd0e2d LibC: Implement various things to get GNU bc building and running.
Looks like that's all we needed, and bc now runs. :^)

6fc3c38324 Start working on a simple graphical font editor.
Editing fonts by editing text files is really slow and boring.
A simple font editor seems like a good way to take LibGUI for a spin.

9153666e72 Userland: /bin/ls shouldn't display inode numbers by default.
Added the -i option to ls which turns on inode number display.

e04ba0a83c Add a simple clock window to guitest2.
This is driven by mousedown events right now, since there are no timers.

c4fce9b3f9 Make stat() work on device files again.
FileDescriptor will now keep a pointer to the original inode even after
opening it resolves to a character device.

Fixed up /bin/ls to display major and minor device numbers instead of size
for device files.

e9b948103d Add a /dev/pts filesystem and make PTY allocation dynamic.
You can now open as many PTY pairs as you like. Well, it's actually capped
at 8 for now, but it's just a constant and trivial to change.

Unregistering a PTY pair is untested because I didn't want to start
mucking with that in Terminal right now.

c30e2c8d44 Implement basic chmod() syscall and /bin/chmod helper.
Only raw octal modes are supported right now.
This patch also changes mode_t from 32-bit to 16-bit to match the on-disk
type used by Ext2FS.

I also ran into EPERM being errno=0 which was confusing, so I inserted an
ESUCCESS in its place.

7455f5ea42 Expose the kernel log buffer through /proc/dmesg.
Also add a /bin/dmesg program for convenience.

c95228b128 Add support for removing directories.
It's really only supported in Ext2FS since SynthFS doesn't really want you
mucking around with its files. This is pretty neat though :^)

I ran into some trouble with HashMap while working on this but opted to work
around it and leave that for a separate investigation.

35c06f1520 LibGUI: More work on GCheckBox.
- Make it track the mouse cursor just like GButton does so that changes only
  get committed if the mouseup event happens while inside the widget rect.

- Draw a focus rect around the box when appropriate.

- When focused, support toggling the checked state with the space bar.
