ef4e9860fd WindowServer: Convert the remaining menu APIs into messages. 2019-02-13 21:47:14 +01:00
Andreas Kling
cf432b4c3d WindowServer: Refactor more of the menu APIs to be message-based. 
This is all pretty verbose but I can whittle it down later. :^)

fbbf57b61c Rename GUI_Event to GUI_ServerMessage. 
Now that communication is becoming bidirectional, "event" is no longer right.

4f98a35beb WindowServer: Begin refactoring towards a fully asynchronous protocol. 
In order to move the WindowServer to userspace, I have to eliminate its
dependence on system call facilities. The communication channel with each
client needs to be message-based in both directions.

c5a00a56c8 WindowServer: Put a clock in the top right corner of the screen. 
This way we don't even need the Clock app anymore. Very cool :^)

961783e0df Let's have makeall.sh build with make -j2. 
The full rebuild keeps getting slower, this makes it a bit more bearable.

d74b131c27 Add a little About app and hook it up to the system menu's "About..." entry. 
Added icons and customizable text alignment to GLabel.

f3c8821b0f Bootloader: Bump sector count once again. 
This is starting to get cramped. I wonder how much longer this hilarious
frankenloader will be able to boot us.

111589a558 Kernel: Make sure processes always start out with fds 0, 1 and 2 open. 
If we don't have a TTY for the process, fall back to /dev/null.

4b8133e925 WindowServer: Clean up any menu objects on process exit. 
..and now that this works, implement the Quit menu action in Terminal. :^)

f311d0f353 Kernel: Don't bother trying to pass environment to init's testing processes. 2019-02-12 10:19:52 +01:00

db98327bdc Plumb menu item activation events from WindowServer to clients. 
GMenu now has an "on_item_activation" callback that fires whenever one
of its items are activated. The menu item identifier is used to distinguish
between items.

Use this to implement font switching in Terminal. :^)

9c1c885483 WindowServer: Add locking and fix coalesced invalidation race. 
WSWindowManager::invalidate() had a bug where it would mark the entire screen
rect as dirty, but it wouldn't scheduled a deferred recompose.

This would cause any subsequent calls to invalidate(Rect) to be coalesced
with the pending compose, but the pending compose never happened.

431e7bf085 PS2MouseDevice: Add current buffer size to debug logging. 2019-02-12 09:22:55 +01:00

133706d697 Add API's and plumbing for WindowServer clients to make menus. 2019-02-12 00:52:19 +01:00

14c0f18de9 Kernel: Update block cache on write. 
If a block is present in the cache, just overwrite the cached block.
 2019-02-11 13:18:24 +01:00

26230c0647 WindowServer: Remove "unsafe" flag in WSMessageLoop::post_event(). 
This hack is no longer needed now that we have a Finalizer process that can
take locks without having to worry about the interrupt flag.

f8951afe17 Ext2FS: Fix broken logic for accessing inode and block bitmaps. 
This logic only worked for the very first block group.

298a49c688 IDEDiskDevice: Detect disk errors and report failure to clients. 
Previously we'd just fail silently if there was an I/O error of any kind.
 2019-02-11 11:38:14 +01:00

443b043b49 WindowServer: Start implementing a menu system. 
I'm going with a global top-of-the-screen menu instead of per-window menus.
The basic idea is that menus will live in the WindowServer and clients can
create menus via WindowServer requests.

6b2d2cc5e3 Create /dev files for null, full, zero and random. 2019-02-11 06:59:28 +01:00

18962bf102 Kernel: Oops, the kernel image access validator thought 0x0 was allowed. 
We forgot to look at the ELF segment type when validating accesses.
We should only consider accesses inside non-empty LOAD segments.
 2019-02-11 06:05:12 +01:00
Andreas Kling
7014daa235 Kernel: Add an LRU block cache. 
This papers over some of the incredibly inefficient access patterns in the
Ext2FS implementation for a while longer. :^)

ae4811fbae ProcFS: Show region flags in /proc/PID/vm 
It's useful to be able to see the readable, writable and bitmap flags.
 2019-02-10 13:02:38 +01:00
Andreas Kling
6103e374cc Kernel: Drop the "helper" region after ELF load is finished. 
The individual segment mappings will keep the VMObject alive.

9860e55047 Kernel: Put page fault logspam behind PAGE_FAULT_DEBUG. 2019-02-10 11:37:59 +01:00
Andreas Kling
5e8d6b1bf4 Base: Rename /users to /home. 
I didn't like seeing /users next to /usr. /home looks nicer.

2def3d8d3f LibGUI: Start adding an automatic widget layout system. 
My needs are really quite simple, so I'm just going to add what I need
as I go along. The first thing I needed was a simple box layout with
widgets being able to say whether they prefer fixed or fill for both
their vertical and horizontal sizes.

I also made a simple GStatusBar so FileManager can show how many bytes
worth of files are in the current directory.

2cf1dd5b6f Move apps into a top-level Applications/ directory. 2019-02-10 08:35:01 +01:00

cc04ba9cc9 ProcFS: /proc/sys entries should always be regular 644 files. 2019-02-10 06:10:01 +01:00

4d5fe39494 FileManager: Start building a file manager. 2019-02-09 09:22:04 +01:00

c4e984ca49 Kernel: Allow mmap() with a size that's not a multiple of page size. 
We just round it up to the next multiple of page size anyway.

fa241747af Kernel: When donating ticks to a lock holder, cap the donation. 
When donating ticks to a lock holder, never donate more ticks than
that process would normally get from the scheduler.

6274208eb9 Ext2FS: Fix bitmap overrun when reaching outside the first block group. 2019-02-08 17:14:51 +01:00

a6f9ddbb58 Let's have two wallpapers installed so we can test switching. 2019-02-08 17:14:47 +01:00
Andreas Kling
d4ba155711 Kernel: Break retain cycle between Inode and VMObject. 
There's no need for an Inode to keep its corresponding VMObject alive.
Obviously there are huge benefits to keeping a filesystem cache,
but leaking everything is hardly the right strategy. :^)
 2019-02-08 16:40:48 +01:00

e1be5a468d Userland: Add a /bin/pape helper program to switch the desktop wallpaper. 2019-02-08 16:22:54 +01:00

33d34d9b26 Kernel: Use a Lockable<bool> for sysctl booleans as well. 2019-02-08 16:18:24 +01:00

f8fc892bac Remove _fs_contents.stock and generate it on the fly instead. 2019-02-08 09:56:39 +01:00
Andreas Kling
a3799cb71e ProcFS: Add sysctl strings. 
They are backed by a Lockable<String> to ensure that access is synchronized.

7e623e7ff2 Process: Dump regions when a ring0 process crashes. 2019-02-08 09:45:53 +01:00
Andreas Kling
90d3375dc2 WindowServer: Support desktop wallpapers. 
For now, you don't get to choose the wallpaper, but it's still pretty cool.
 2019-02-08 08:45:59 +01:00
Andreas Kling
2736957701 Ext2FS: Fix dumb bitmap size bug in *_inode_allocation_state(). 2019-02-08 08:43:08 +01:00
Andreas Kling
736e852525 LibC: Implement enough missing stuff to get bash-5.0 running. :^) 2019-02-08 02:38:21 +01:00

f4bce03716 Kernel: When validating a string read, validate the pointer first. 
Calling strlen() on an invalid pointer is just gonna crash the process.

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.
 2019-02-07 12:21:17 +01:00

ee2bb98b88 Kernel: Increase default time slice to 20ms. 2019-02-07 11:53:45 +01:00
