This feels like it was a refactor transition kind of conversion. The
places that were relying on it can easily be changed to explicitly ask
for the ptr() or a new vaddr() method on Userspace<T*>.
FlatPtr can still implicitly convert to Userspace<T> because the
constructor is not explicit, but there's quite a few more places that
are relying on that conversion.
Some calls of copy_to_user were converting Userspace<T*> to
Userspace<U*> via the implicit conversion to FlatPtr. Change them to use
the static_ptr_cast overload that is designed to express this conversion
A series of refactors changed Threads to always have a name, and to
store their name as a KString. Before the refactors a StringBuilder was
used to format the default thread name for a non-main thread, but it is
since unused. Remove it and the AK/String related header includes from
the thread syscall implementation file.
The processor parameter values are displayed with two decimal places by
default. However, when these values become very large and exceed about 7
text symbols, the text is too long to fit the label and it'll simply not
show up. This commit fixes that by disabling the decimal place for such
large values, which allows us to show values up to 9,999,999, be it
only at integer precision.
Some nuances in the FLAC loading code can do well with an explanation,
as these non-obvious insights are often the result of long and painful
debugging and nobody should touch the affected code without careful
deliberation.
(Of course, secretly I just want people to maintain my loader code.)

This fixes all current code smells, bugs and issues reported by
SonarCloud static analysis. Other issues are almost exclusively false
positives. This makes much code clearer, and some minor benefits in
performance or bug evasion may be gained.
When the resulting week is in the previous year, we need to check if the
previous year is a leap year and can potentially have 53 weeks, instead
of the given year.
Also added a comment to briefly explain what's going on, as it took me a
while to figure out.
This change makes it easier to generate a new field. Instead of using
hard-coded values everywhere, we now just need to keep track of
the Difficulty enum value.
This adds a dialog window which allows us to customize the size of the
board and the amount of mines that will be placed.
The current max amount of mines is 50% of the total number of cells
due to the fact that the generator algorithm takes too long to create a
board for higher percentages of mines.
...and change the parameter types from i64 to double, as predicted by
a FIXME. The issue here is that integer division with a negative
dividend doesn't yield the same result as floating point division
wrapped in floor().
Additionally, the `days` variable needs to be signed.
Two instances of comparing a bool with == true or == false, and one
instance where we can just return an expression instead of checking it
to return true on succeess and false on failure.

Some places the warning is suppressed, because we do not want a const
object do have non-const access to the returned sub-object.
In AK::Function::CallableWrapper::init_and_swap(), clang-tidy wants us
to mark the destination argument as pointer to const, which doesn't work
because we use placement new to construct a move'd *this into.
cert-dcl50-cpp: No variadic functions, suppressed in RefCounted and
ThreadSafeRefCounted for implementing the magic one_ref_left and
will_be_destroyed functions.
cert-dcl58-cpp: No opening ::std, suppressed in the places we put names
in ::std to aid tools (move, forward, nullptr_t, align_val_t, etc).
Either not returning *this, or in the case of Variant, not checking for
self assignment. In AK::Atomic, we can't return *this due to the wrapper
semantics Atomic implements.
Using `l` for long double causes a clang-tidy warning, so use all caps
suffixes for all of the AK::abs() overloads for consistency. Also, avoid
leaking the internal __DEFINE_GENERIC_ABS macro.
The definition of VERIFY_NOT_REACHED() as `assert(false)` causes the
tool to suggest converting it to a static_assert. Which doesn't make
any sense in context for what the macro is trying to do: crash the
program at runtime.
If we want to use clang-tidy on the codebase, we'll need to build
clang-tidy from an LLVM that has been patched and built with Serenity
cross-compilation support.
Add a basic clang-tidy configuration that enables checks from the
following categories:
- bugprone
- cert
- clang-analyzer
- concurrency
- misc
- performance
- portability
- readability
The noisiest rules that have conflicts with the project style guide or
accepted practices have been turned off.
There's absolutely more work to be done here before we could consider
setting any of these warnings as errors and enforcing them in CI, but
committing a project clang-tidy configuration should help the rules
become more visible and let other contributors take a crack at tweaking
rules and/or finding possible bugs.
Sadly the cpp-core-guidelines and modernize categories are very, very
noisy. If we want to enable rules from these categories, they would need
to be on a rule by rule basis.
Serenity defines a protected range of memory that must not be mmapped,
and is apparently reserved for kernel tasks. In this case, the protected
range is anything below 0x800000.
However, in its default setting, binutils chooses the memory address
0x400000 as the mapping address for executables that do not have PIE
enabled, resulting in mmap being unable to map the file unless the load
address has been overwritten at link time or if it's a PIE.
To mitigate this, move the default base address somewhere outside of
that range (and preferably not anywhere close near the beginning of the
useable virtual memory space, to avoid running into it during sequential
allocations).
