e0cdc5db0d Ext2FS: Reduce debug spam in block allocation. 2019-04-25 22:05:32 +02:00

de4b77ef27 WindowServer: Ignore title change notifications for non-normal windows. 2019-04-25 17:38:16 +02:00

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. :^)

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.

d5578826af Kernel: Make it possible to look up FIFO's by ID. 
This will be useful when implementing the /proc/PID/fd/N links where N is
a file descriptor referring to a FIFO.

eadcf720c0 Userland: Add a simple /bin/echo program. 2019-04-25 04:42:09 +02:00

737315c228 GTextEditor: Improve cursor positioning accuracy when using a mouse. 
Put the cursor on the left or right side of a glyph when clicking it based
on distance to middle of glyphs. This is such an obvious change that makes
a small but noticeable difference in feel. :^)

7a5525edf4 GTextEditor: Go a little past the cursor for Home/End scroll-into-view. 
When jumping to the start of a line, or to the end of a line, scrolling two
pixels past the end yields a pleasant effect.

2c51bc92af GTextEditor: Always call did_change() before set_cursor(). 
This is not very obvious and I need to come up with a better design, but for
now just make sure to call did_change() before calling set_cursor().
This is needed because set_cursor() will try to scroll the cursor into view,
and for right-aligned text, did_change() may change the content rect which
needs to be reflected by the time we call scroll_cursor_into_view().

4e715dbc71 GTextEditor: Account for the GFrame border in the painting code. 
We were forgetting to translate the painter by the frame_thickness().
With this fixed, we can also do proper vertical centering of lines for
single-line editors, and things suddenly look nicer than ever! :^)

3543236e8f GScrollableWidget: The visible_content_rect() should be max content_size(). 
When computing the visible content rect, constrain the result to the content
size. The content shouldn't feel responsible for painting anything outside.

7dc4078a73 SharedGraphics: Add is_right_text_alignment(TextAlignment) helper. 
This seems a tad bit more future-proof than manually checking all the valid
right-side TextAlignment values in clients.
 2019-04-24 23:46:19 +02:00
Andreas Kling
0c88ce9ee3 GTextEditor: Expand the content "to-fill" for right aligned text. 
When using a right-side text alignment, hook the resize event to make sure
that the content width is at least frame_inner_rect().width() wide.

This allows us to use content_width() as the anchor point for right aligned
text, rather than using the frame inner rect, which was clearly wrong in
the overflow case.

f1eba2295d GTextEditor: Make the line_widget_rect() span the widget horizontally. 2019-04-24 23:15:15 +02:00
Andreas Kling
4bea3a4aa6 GTextEditor: Turn off the ruler by default. 
You're usually not gonna want the ruler. TextEditor can enable it manually.

5c240af3f7 GTextEditor: Fix line_content_rect() behavior with custom alignments. 2019-04-24 22:46:27 +02:00
Andreas Kling
62f0aae4ca GTextEditor: Add support for different text alignments. 
Currently only CenterLeft and CenterRight are supported, but it would be
very straightforward to add other alignments as well.

16f6a3af3c Allow passing extra args to qemu via a SERENITY_EXTRA_QEMU_ARGS env var. 2019-04-24 21:06:16 +02:00

c1b310c5bf Build: Let's skip the --gc-sections linker option for now. 2019-04-24 01:57:51 +02:00
Andreas Kling
956bd23aae WindowServer+TaskBar: Add a taskbar window button popup menu. 
This patch only hooks up the minimize and unminimize actions.

c5c4e54a67 Kernel: Process destruction should destroy all child threads. 
We were only destroying the main thread when a process died, leaving any
secondary threads around. They couldn't run, but because they were still
in the global thread list, strange things could happen since they had some
now-stale pointers to their old process.

e2cd572e60 WindowServer: Add some padding to the window switcher items. 2019-04-23 22:01:33 +02:00

0c898e3c2c Put assertions behind a DEBUG flag to make it easy to build without them. 2019-04-23 21:52:02 +02:00
Andreas Kling
f3754b8429 Build: Pass --gc-sections to the linker in all builds. 
This removes unused sections from the output and reduces the binary size
of everything we compile.

f042b3adeb Kernel: Make the right shift key work. 
I never realized the right shift key wasn't hooked up since my left pinky
always hovers over the left shift key, ready to rock.

f520d87097 WindowServer: Remove debug spam about activating non-normal windows. 2019-04-23 20:46:10 +02:00

02e5d55832 LibGUI: Don't bother setting a title on tooltip windows. 2019-04-23 20:45:42 +02:00
Andreas Kling
8495abd140 GWindow: Don't send InvalidateRect message with 0 rects to WindowServer. 
This could happen if GWindow::hide() was called while a window had pending
repaint rects. The deferred_invoke() lambda in GWindow::update() would
eventually run, but by then, hide() had cleared all pending rects.

b041fc57de Ext2FS: Bitmaps aren't always at full capacity. 
Block bitmaps only have (blocks_per_group) entries, while inode bitmaps
only have (inodes_per_group) entries.
 2019-04-23 16:21:07 +02:00
Andreas Kling
14ceabeca8 Ext2FS: More bitmap misunderstanding cleanups. 
Inode bitmaps are also only ever one block.
 2019-04-23 15:07:07 +02:00
Andreas Kling
1bf37db9a9 Ext2FS: Simplify block bitmap stuff. 
Block bitmaps are only ever one block in size. I don't know why I thought
otherwise, but use this info to simplify the code. :^)

58240fdb33 Do a pass of compiler warning fixes. 
This is really making me question not using 64-bit integers more.

243e1d8462 Kernel: Use rep insw/outsw for IDE transfers. 
There are much faster ways to do disk transfers, but I'm not implementing
those today. In the meantime, this is slightly nicer. :^)

2d7cad6a16 Kernel: Make sure we don't use any FPU/MMX/SSE instructions. 2019-04-22 23:38:33 +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(). :^)

6693cfb26a Kernel: Don't use MMX memcpy() in the kernel. 
I just discovered the hard way that clobbering FPU/MMX/SSE registers in the
kernel makes things very confusing for userspace (and other kernel threads.)

Let's banish all of those things from the kernel to keep things simple.
