This commit un-confuses the many specialisations of AK::Traits, and
makes it work correctly for all integral types.
Prior to this, `AK::Traits<size_t>` would've been instantiating the
base Traits implementation, not `Traits<u32>` or `Traits<u64>`.
This is Abstract Operation is required for the majority of
InstantConstructor's and InstantPrototype's methods.
The implementation is not entirely complete, (specifically 2 of the
underlying required abstract operations, ParseTemporalTimeZoneString
and ParseISODateTime are missing the required lexing, and as such are
TODO()-ed) but the majority of it is done.
This is an AK::GenericLexer that exposes helper methods for parsing
date and time related literals (years, months, days, hours, minutes,
seconds, fractional seconds & more)
Perform signed integer shifts, addition, subtraction, and rotations
using their corresponding unsigned type. Additionally, mod the right
hand side of shifts and rotations by the bit width of the integer per
the spec. This seems strange, but the spec is clear on the desired
wrapping behavior of arithmetic operations.
The WASM spec tests caused a stack overflow when generated with wat2wasm
version 1.0.23, which ships with homebrew. To give feature parity,
manually download the same version from GitHub packages for Ubuntu.
Document the dependencies of the WASM spec tests option, as well.
macOS's C library is not a good neighbor and doesn't ensure that
the entry in struct hostent's h_addr_list are aligned properly for
a char const*. In Socket::connect, use ByteReader instead of a c-style
cast to work around this possible misalignment.
Before this change, parent widgets such as Buttons or Labels
were stealing drop events their parents.
I noticed it during drag-n-dropping files into visualization widgets
in Sound Player (which takes practically the entire application size
and gave impression that drop events weren't supported in the app
at all).
The IPCCompiler was using GENERATE_DEBUG_CODE, which was missing from
AK/Debug.h.in, and plain old DEBUG. Let's just use the one that
was already in the debug header, but unused.
This enables the Lock class to block a thread even while the thread is
working on a BlockCondition. A thread can still only be either blocked
by a Lock or a BlockCondition.
This also establishes a linked list of threads that are blocked by a
Lock and unblocking directly unlocks threads and wakes them directly.
It's possible that a timer may have been queued to be executed by
the timer irq handler, but if we're in a critical section on the
same processor and are trying to cancel that timer, we would spin
forever waiting for it to be executed.
This re-arranges the order of how things are initialized so that we
try to initialize process and thread management earlier. This is
neccessary because a lot of the code uses the Lock class, which really
needs to have a running scheduler in place so that we can properly
preempt.
This also enables us to potentially initialize some things in parallel.
Instead of each PhysicalPage knowing whether it comes from the
supervisor pages or from the user pages, we can just check in both
sets when freeing a page.
It's just a handful of pointer range checks, nothing expensive.
There appears to be no reason why the process registration needs
to happen under the space spin lock. As the first thread is not started
yet it should be completely uncontested, but it's still bad practice.
If no other thread is ready to be run we don't need to switch to the
idle thread and wait for the next timer interrupt. We can just give
the thread another timeslice and keep it running.
Context menu entries like evaluate expression and
move execution to line action should only be enabled
when a debug session is running. Otherwise they should
be disabled.
This commit disables the run button while we
are in debug mode. Otherwise the stop button
gets disabled when we run the program while
we are in debug mode. This would prevent us
from exiting the debug mode.
