Since NonnullRefPtr and NonnullOwnPtr cannot be null, it is pointless
to convert them to a bool, since it would always be true.
This patch makes it an error to null-check one of these pointers.
It should be possible for the CSS parser to fail, and we'll know it
failed if it returns nullptr. Returning RefPtr's makes it actually
possible to return nullptr. :^)
This simple helper escapes '<', '>' and '&' so they can be used in HTML
text without interfering with the parser.
Use this in IRCClient to prevent incoming messages from messing with
the DOM :^)
This function parses a partial DOM and returns it wrapped in a document
fragment node (DocumentFragment.)
There are now two entrances into the HTML parser, one for parsing full
documents, and one for parsing fragments. Internally the both wrap the
same parsing function.
It's not safe to use a raw pointer for Process::m_tty. A pseudoterminal
pair will disappear when file descriptors are closed, and we'd end up
looking dangly. Just use a RefPtr.
Scheduling priority is now set at the thread level instead of at the
process level.
This is a step towards allowing processes to set different priorities
for threads. There's no userspace API for that yet, since only the main
thread's priority is affected by sched_setparam().
Oops, we were creating these and then throwing them away. They will
get instantiated a bit later, when we bring up the mounts in /etc/fstab
from userspace.
This allows us to get rid of all the custom 64-bit division helpers.
I wanted to do this ages ago but couldn't get it working. Turns out it
was unstable due to libgcc using the regular ABI and the kernel being
built with -mregparm=3.
Now that we build the kernel with regular calls, we can just link with
libgcc and get this stuff for free. :^)
Add LayoutPosition and LayoutRange classes. The layout tree root node
now has a selection() LayoutRange. It's essentially a start and end
LayoutPosition.
A LayoutPosition is a LayoutNode, and an optional index into that node.
The index is only relevant for text nodes, where it's the character
index into the rendered text.
HtmlView now updates the selection start/end of the LayoutDocument when
clicking and dragging with the left mouse button.
We don't paint the selection yet, and there's no way to copy what's
selected. It only exists as a LayoutRange.
Note that you are not allowed to remove the very last editor.
These keybinds are all temporary while I figure out what the right ones
should be. I'm not exactly sure how, but it'll reveal itself. :^)
When adding a widget to a parent, you don't always want to append it to
the set of existing children, but instead insert it before one of them.
This patch makes that possible by adding CObject::insert_child_before()
which also produces a ChildAdded event with an additional before_child
pointer. This pointer is then used by GWidget to make sure that any
layout present maintains the correct order. (Without doing that, newly
added children would still be appended into the layout order, despite
having a different widget sibling order.)
Renamed "Position" to "Elapsed". "channel/channels" automatically
changes now when more than one channel exist. The current file name
is now displayed in the window title.
m_loaded_samples was incremented with the value of the processed
buffer. This causes m_loaded_samples to be bigger at some point
than m_total_samples when downsampling, as the buffer would contain
more samples than actually loaded.
By default, disk_benchmark will now use the O_DIRECT flag, causing it
to bypass the kernel's disk caches. This gives you "disk performance"
numbers rather than "disk cache performance" numbers.
You can use "disk_benchmark -c" to enable the caches.
Fixes#703.
Files opened with O_DIRECT will now bypass the disk cache in read/write
operations (though metadata operations will still hit the disk cache.)
This will allow us to test actual disk performance instead of testing
disk *cache* performance, if that's what we want. :^)
There's room for improvment here, we're very aggressively flushing any
dirty cache entries for the specific block before reading/writing that
block. This is done by walking the entire cache, which may be slow.
LibAudio now supports pausing playback, clearing the buffer queue,
retrieving the played samples since the last clear and retrieving
the currently playing shared buffer id
