The height of the bottom color container was cut off at the bottom.
This adjusts the heights and also the primary/secondary color
widget so that it's in line.
- Make sure that all the Repeat ops are reset (otherwise the operation
would not be correct when going over the Repeat op a second time)
- Make sure that all matches that are allowed to fail are backed by a
fork, otherwise the last failing fork would not have anywhere to
return to.
Fixes#9707.
The dynamic loader was mistakenly assuming that there are only two types
of program load headers: text (RX) and data (RW).
Now that we're linking with `-z separate-code`, we will also get some
read-onlydata (R) segments. These can be memory-mapped directly without
making a private per-process copy.
To solve this, the code now instead separates the headers into map/copy
instead of text/data. Writable segments get copied, while non-writable
segments get memory-mapped. :^)
This commit relayouts the BreadcrumbButtons on resize to a shrunken
state if they don't fit. It also caps the button width to 100px to
avoid overflowing the widget.
Add a new Color category to the Filter menu. Add the Grayscale
filter under Filter->Color to turn the selected layer to grey colors.
Created GrayscaleFilter.h. Modify Filter.h to allow filters
without parameters.
This patch changes the HTML formatting (where to put newlines, etc...)
to better match commonmark's test cases. This has minimal effect of the
correctness of our markdown implementation, but makes it easier to test.
Changes:
- Use <em> instead of <i>.
- Newline before end of code block.
- <hr /> instead of <hr>.
- Newline before first list item.
- Newline between lines of a paragraph.
- Trim whitespace on lines of paragraphs.
Tests passed: 33/652 -> 87/652
If the domain/group/key doesn't exist in the config, exit with
non-zero status and don't print out anything.
Previously the CLI would print a single empty line if the config
value was not found with LibConfig. Now, we use the proper
`Config::Client::the().read_string()` API which can return an
`Optional` type indicating failure.`
This leads to a bad pattern where anyone could create an RNG or a
Console object. Instead, let's just use the common pattern of a static
method to instantiate a new object and return it wrapped by a
NonnullRefPtr.
Before of this change, many specific classes to VirtIO were in the
Kernel namespace, which polluted it.
Everything should be more organized now, but there's still room for
improvement later.
This class member was used only to determine the device type when
printing messages to the debug log. Instead, remove this class member,
and add a quick way to find the device type according to how the VirtIO
specification says to do that.
This simplifies construction of VirtIODevices a bit, because now the
constructor doesn't need to ask for a String identified with the device
type.
This class as a CharacterDevice really was not useful, because you
couldn't even read from it.
Also, the random number generator interface should be the /dev/random,
so any other interface to get random numbers is generally not a good
idea.
Instead, let's keep this functionality as an entropy source for random
numbers generation, but without exposing a device node.
Currently when clicking the percentage toggle, there is a delay
in moving the applet window position. This is because after
the applet is resized, the applet area is repositioned
asynchronously. This takes advantage of the new AppletAreaRectChange
event to reposition the slider window when necessary.
Applets and windows would like to be able to know when the applet
area has been resized. For example, this happens asynchronously after
an applet has been resized, so we cannot then rely on the applet area
position synchronously after resizing. This adds a new message
applet_area_rect_changed and associated Event AppletAreaRectChange,
and the appropriate virtual functions.
This tells the linker to not combine read-only data and executable code,
instead favoring multiple PT_LOAD headers with more precise permissions.
This greatly reduces the amount of executable pages in all our programs
and libraries.

As you can see, we go from 0x2fc77c bytes of executable memory down to
0x25f6c9 (a ~20% reduction!) The memory that was previous executable is
now simply read-only instead. :^)
GNU ld sometimes generates zero-sized PT_LOAD headers when running with
the "-z separate-code" option. Let's not choke on such headers, we can
just ignore them and move along.
The prior commits add the `DrawMode` enum to keep track of where
the shape is being drawn from. With this addition, the prior `Mode`
enum name is confusing, so this commit renames it to `FillMode` to
be more explicit :^)
Essentially the same logic as the prior commit, but now for the
`RectangleTool` class. Pressing `alt` lets you draw the rectangle
with the starting position as the center.
Like other common image editing applications, now if you press
`alt` while drawing an ellipse, it uses the starting position as
the center of the ellipse as opposed to one of the corners of the
bounding rect.
The EllipseTool class now keeps track of a `DrawMode`, which is
either `DrawMode::FromCorner` (default), or `DrawMode::FromCenter`
(the option added by this commit).
The `draw_using()` function was modified to now take in the start
and end positions and construct the `ellipse_intersecting_rect`
itself, since we need to construct it differently based on the
drawing mode.
This change removes the manually created model class
in order to use a generic GUI::ItemListModel.
Besides from code reusability, it also makes the list
searchable as you type.
We now expose the `USBDevice`'s address in the SysFS object. This means
that device addresses are no longer determined by the name of the file
in the `/bus/usb/` directory. This was an incorrect way of determining
device address, as a standard PC can have multiple USB controllers
(and hence multiple buses) that can have overlapping device IDs.
The new Statistics utility is now used when calling 'time -n' to get
some more information of the timings. For now only the standard
deviation is given in addition to the average.
This commit completely undos #9645 because everything that touched moved
into AK::Statistics.
It's possible for the module to request too many locals, we now reject
such modules instead of trying to allocate space for them.
The value itself is chosen arbitrarily, so future tweaks _might_ be
necessary.
