Most of the time, we cannot resolve a `calc()` expression until we go to
use it. Since any `<length-percentage>` can legally be a `calc
()`, let's store it in `LengthPercentage` rather than make every single
user care about this distinction.
The previous static functions are now methods of their respective
CalcFoo structs, but the logic has not changed, only that they work
with CalculationResults instead of converting everything to floats.
calc() sub-expressions can return a variety of different types, which
then can be combined using the basic arithmetic operators. This class
should make that easier to deal with, instead of having to handle all
the possible combinations at each call site. :^)
We take the Layout::Node as a pointer not a reference, since later we'll
need to call these functions when resolving to `<number>` or `<integer>`
which don't use those, and we don't want to force users to pass them in
unnecessarily.
See https://www.w3.org/TR/css-values-3/#calc-type-checking
If the sub-expressions' types are incompatible, we discard the calc() as
invalid.
Had to do some minor rearranging/renaming of the Calc structs to make
the `resolve_foo_type()` templates work too.
While playing around with getting serenity to run on my main desktop
machine I wanted a way of easily updating my physical serenity
partition.
To use it you just need to:
- Create and format your local partition to ext4
- Set `SERENITY_TARGET_INSTALL_PARTITION` to the partition /dev path.
- Run the `install-native-partition` build target.
Example:
$ export SERENITY_TARGET_INSTALL_PARTITION=/dev/nvme1n1p3
$ cd serenity/Build/x86_64
$ ninja install-native-partition
As make<T> is infallible, it really should not be used anywhere in the
Kernel. Instead replace with fallible `new (nothrow)` calls, that will
eventually be error-propagated.
This stops these actions from being activated with Ctrl+[1,2,3] or the
command palette.. Switching to table or columns view would just hide
all the icons, so let's not make those options available.
A mutex is useful when we need to be able to block the current thread
until it's available. This is overkill for OpenFileDescriptor.
First off, this patch wraps the main state member variables inside a
SpinlockProtected<State> to enforce synchronized access. This also
avoids "free locking" where figuring out which variables are guarded
by which lock is left as an unamusing exercise for the reader.
Then we remove mutex locking from the functions that simply call through
to the underlying File or Inode, since those fields never change anyway,
and the target objects perform their own synchronization.
