0ebaa35aa1 Kernel: Let the process argv arrays be null-terminated. 
Seems like this is expected. I don't know why I thought it wasn't.

8bb18fdc56 Kernel: Get rid of Unix namespace. 
This is no longer needed as the Kernel can stand on its own legs now
and there won't be any conflict with host system data types.

Andreas Kling
e911caeb10 Kernel: Fix dumb race in Scheduler::yield() debug code. 
It was perfectly possible for Scheduler::yield() to get interrupted after
setting s_in_yield but before disabling interrupts.
 2019-01-23 05:06:47 +01:00
Andreas Kling
07f4c8b01b VFS: Get rid of the deprecated Inode::write(const ByteBuffer&). 
Fix the only remaining call site to use Inode::write_bytes().
 2019-01-23 04:59:47 +01:00

906685e238 Ext2FS: Implement writing into inodes with arbitrary offset and length. 
Okay, this is pretty cool. :^) There are some issues and limitations for
sure but the basic functionality is there.
 2019-01-23 04:29:56 +01:00

29dfb4ae13 Ext2FS: Factor out block list generation and writing into functions. 2019-01-23 03:03:44 +01:00

Andreas Kling
05f18febb6 Ext2FS: Delete inodes when their link count goes to zero. 2019-01-22 16:34:24 +01:00
Andreas Kling
bda0c935c2 Add unlink() syscall and /bin/rm. 
This patch adds most of the plumbing for working file deletion in Ext2FS.
Directory entries are removed and inode link counts updated.
We don't yet update the inode or block bitmaps, I will do that separately.
 2019-01-22 07:03:44 +01:00

2f2f28f212 Kernel: Refactor Region/PageDirectory ownership model. 
Make PageDirectory retainable and have each Region co-own the PageDirectory
they're mapped into. When unmapped, Region has no associated PageDirectory.

This allows Region to automatically unmap itself when destroyed.
 2019-01-22 05:06:22 +01:00
Andreas Kling
afccbe51a4 VFS: Place new files in the correct subdirectory. 
Oops, every new file was ending up in the root directory.
Also make sure we create the inode in the same FS as the parent directory.
 2019-01-22 03:56:34 +01:00

4d1d875ca7 Remove some unused errno.h duplicates. 2019-01-22 01:12:53 +01:00
Andreas Kling
f70136a324 Kernel: Support open() with O_CREAT. 
It's now possible to create zero-length files! :^)
Also hook up the new functionality in /bin/touch.

a47f33bed3 WindowServer: Map shared GraphicsBitmaps read-only on the server side. 2019-01-21 19:27:23 +01:00
Andreas Kling
f9fcb682ec Keyboard: Use some of the existing defines instead of hard-coded numbers. 2019-01-21 07:30:46 +01:00
Andreas Kling
51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency. 
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.
 2019-01-21 07:28:04 +01:00
Andreas Kling
aefbbeb3cb Flesh out keyboard event support a bit more. 2019-01-21 07:27:26 +01:00
Andreas Kling
76a2881793 Mark the two Regions used GraphicsBitmaps as explicitly shared. 
This fixes a goofy problem where forking a GUI process would cowify the
GraphicsBitmap for everyone making a hue confusing mess.

d1af5c97ca Kernel: Process should drop any framebuffer regions on exec(). 2019-01-21 03:22:03 +01:00
Andreas Kling
61e50780aa Kernel: Forked processes should inherit arguments and environment. 2019-01-21 02:59:58 +01:00

Andreas Kling
291922b1af WindowServer: Show PID and window ID in title bars for now. 
This is useful for debugging since I'm often wondering which process some
window belongs to (and what the window ID is.)
 2019-01-21 02:43:38 +01:00
Andreas Kling
e6fc84e234 Kernel: Make /proc/PID/fds display something useful for character devices. 2019-01-21 02:33:01 +01:00

786b903d62 WindowServer: Don't invalidate already frontmost window for moving to front. 2019-01-21 02:19:08 +01:00
Andreas Kling
e115ae5641 Kernel: Clone Process::m_gids on fork() and hook up any framebuffer region. 2019-01-21 01:49:30 +01:00
Andreas Kling

6c4f1bad09 guitest2: Add a simple launcher so I can easily spawn more Terminals.

3271c115e2 WindowServer: Only blit dirty rect of windows to back buffer. 
Previously we'd blit every pixel in every window that intersected any dirty
rect to the back buffer. With this patch, we limit ourselves to blitting the
pixels inside the actual dirty rects.

There's still a lot of optimizations to make in this code.
