45fba60ab5 Kernel: select() should fail with EBADF if any set contains an invalid fd. 2019-01-30 19:01:31 +01:00

b4e478aa50 Deallocate PTY's when they close. 
This required a fair bit of plumbing. The CharacterDevice::close() virtual
will now be closed by ~FileDescriptor(), allowing device implementations to
do custom cleanup at that point.

One big problem remains: if the master PTY is closed before the slave PTY,
we go into crashy land.

027d26cd5d Add a String::format() and use that in place of ksprintf() in the Kernel. 
You're never gonna be right 100% of the time when guessing how much buffer
space you need. This avoids having to make that type of decision in a bunch
of cases. :^)

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.

ad53f6afd3 LibC: Move Stopwatch thingy into a <serenity.h> header. 
This thing is extremely useful for performance testing so let's put it here.

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.

069d21ed7f Make buttons unpress when the cursor leaves the button rect. 
Implement this functionality by adding global cursor tracking.
It's currently only possible for one GWidget per GWindow to track the cursor.

c7221b7dee Painter: Tell the compiler to flatten Font::draw_glyph(). 
I think that concludes the Terminal stress test optimizations for now.

57fb027216 LibC: Implement setjmp() and longjmp(). 
I think this is correct. The following registers are saved and restored:
EBX, ESI, EDI, EBP, ESP and EIP.

9fa8d4e22f WindowServer: Rename the two painting phases. 
Work now happens in terms of two messages:

    - WM_ClientWantsToPaint
    - WM_ClientFinishedPaint

This feels fairly obvious compared to the old Paint/Invalidate.

bba21adae3 WindowServer: Rename WSEvent to WSMessage. 
Also do the same for WSMessageLoop and WSMessageReceiver. More to come.

7cf3c7461c Refactor GUI rendering model to be two-phased. 
Instead of clients painting whenever they feel like it, we now ask that they
paint in response to a paint message.

After finishing painting, clients notify the WindowServer about the rect(s)
they painted into and then flush eventually happens, etc.

This stuff leaves us with a lot of badly named things. Need to fix that.

8fa7d96f50 SharedGraphics: Import another 8x10 fixed-width font I made. 
It's not perfect yet but it's quite nice to look at so I'll make this the
system default for now. :^)

Andreas Kling
6cc1a9d90a sh: Support basic backspacing on the command line. 
It's weird that I didn't do this sooner. I don't know how many tims
I've had to retype a misspelled command. :^)
