Previously, the device wasn't being created.
The new numbers correspond to those in the FullDevice (which is also
a Linux's full device number).
Also, I've tweaked the permissions to give everyone read-write access
to it.
This means all three window titles are visible, regardless of what the
TitleHeight and BorderThickness values are. :^)
The one exception is when TitleHeight is less than the height of the
title text. WindowManager ensures that the real title height is at
least enough to fit the text, so if the value is set to less than that,
the window titles will start to overlap. So, don't set values that are
impossibly small!
This is quite a radical change. The previous UI was very easy to add new
properties to (just add to the FooRole enum and it automatically
works), but not so nice to use: A ComboBox for selecting a property,
and then a box to edit that property's value. This makes it difficult
to compare different properties or edit multiple together without a lot
of back-and-forth.
This new design gives each property its own editing widgets, with those
categorized into several tabs. To try and avoid increasing the
maintenance burden for this, the UI is generated from the
`windows_tab`, `widgets_tab` and `syntax_highlighting_tab` variables,
which are basically just lists of which properties go in that tab. One
of the `FooProperty.gml` files is loaded to create each property's
widgets.
With the update to GCC 12.1.0, the compiler now vectorizes code with
-O2. This causes vector ops to be emitted, which are not supported in
the Kernel. Add the -mgeneral-regs-only flag to force the compiler to
not emit floating-point and SIMD ops.
By default we enable the Kernel Undefined Behavior Sanitizer, which
checks for undefined behavior at runtime. However, sometimes a developer
might want to turn that off, so now there is a easy way to do that.
When disabling UBSAN, the compiler would complain that the constraints
of the inline assembly could not be met. By adding the alignas specifier
the compiler can now determine that the struct can be passed into a
register, and thus the constraints are met.
This moves all code comprehension-related code to a new library,
LibCodeComprehension.
This also moves some types related to code comprehension tasks (such as
autocomplete, find declaration) out of LibGUI and into
LibCodeComprehension.
Previously, `touch` remained limited to creating files and updating
their current access and modifications time to the current time. It's
now capable of accepting two different timestamp formats with flags `-d`
and `-t` and referencing timestamps of other files with flag `-r`.
`touch` can also update only the last access time with `-a`, only the
last access time with `-m`, or update both as usual. `touch` updates
both left unspecified.
With `-c`, `touch` does not create a file if it doesn't already exist.
Implement futimes() in terms of utimensat(). Now, utimensat() strays
from POSIX compliance because it also accepts a combination of a file
descriptor of a regular file and an empty path. utimensat() then uses
this file descriptor instead of the path to update the last access
and/or modification time of a file. That being said, its prior behavior
remains intact.
With the new behavior of utimensat(), `path` must point to a valid
string; given a null pointer instead of an empty string, utimensat()
sets `errno` to `EFAULT` and returns a failure.
This keeps users from leaking their host environment variables (CFLAGS,
etc.) into Ports, and it keeps us from leaking Port-specific settings
into their dependencies.
