The round trip compress test wants the first half of the byte buffer to
be filled with random data, and the second half to be all zeroes. The
strategy of using memset on ByteBuffer::offset_pointer confuses
__builtin_memset_chk when building with -fsanitize=undefined. It thinks
that the buffer is using inline capacity when we can prove to ourselves
pretty easily that it's not. To avoid this, just create the buffer
zeroed to start, and then fill the first half with the random data.
This allows multiply different kinds of interpreters to be used by the
runtime; currently a BytecodeInterpreter and a
DebuggerBytecodeInterpreter is provided.
This should make it easier to implement multiple types of interpreters
on top of a configuration, and also give a small speed boost in not
initialising as many Stack objects.
Doing that was causing a lot of malloc/free traffic, but since there's
no need to have a stable pointer to them, we can just store them by
value.
This makes execution significantly faster :^)
Previously we'd only only send one DHCP request for network interfaces
which were up when DHCPClient started. If that packet was lost we'd
never send another request for those interfaces.
Also, if an interface were to appear after DHCPClient started (not
that that is possible at the moment) we wouldn't send requests for
that interface either.
This option replaces the use of ENABLE_ALL_THE_DEBUG_MACROS in CI runs,
and enables all debug options that might be broken by developers
unintentionally that are only used in specific debugging situations.
When debugging kernel code, it's necessary to set extra flags. Normal
advice is to set -ggdb3. Sometimes that still doesn't provide enough
debugging information for complex functions that still get optimized.
Compiling with -Og gives the best optimizations for debugging, but can
sometimes be broken by changes that are innocuous when the compiler gets
more of a chance to look at them. The new CMake option enables both
compile options for kernel code.
The compiler couldn't convince itself that these are always initialized
when compiling with Og. They are always initialized before use, because
the only branch where they weren't had VERIFY_NOT_REACHED.
With -Og, all calls to create_kernel_process were triggering -Wnonnull
when creating these lambdas that get implicitly converted to function
pointers. A different design of create_kernel_process to use
AK::Function instead might avoid this awkward behavior.
When compiling the Kernel with Og, the compiler complains that
m_outline_capacity might be uninitialized when calling capacity()
Note that this fix is not really what we want. Ideally only outline
buffer and outline capacity would need initialized, not the entire
inline buffer. However, clang considers the class to not be
default-constructible if we make that change, while gcc accepts it.
This moves the calculation of selected words that was originally
in the TextEditor application to TextEditor in LibGUI.
This allows all applications with text editors to get
this number without having to calculating it themselves.
Previously the buildstep function would obscure error codes because
the return value of the function was the exit code for the sed command
which caused us to continue execution even though one of the build
steps had failed.
With set -o pipefail the return value of the buildstep function is
the real command's exit code.
The view menu contains:
1. A fullscreen option (also accessed by pressing F11).
2. Rotation axis controls (x, y, z, or any combination)
3. Rotation speed controls (No rotation, slow, normal, or fast)
Previously reads and writes to /dev/zero, /dev/full, /dev/null and
/dev/random were limited to 4096 bytes.
This removes that restriction so that users can enjoy more zero bytes
in their buffers.
Previously we'd just dump those packets into the network adapter's
send queue and hope for the best. Instead we should wait until the peer
has sent TCP ACK packets.
Ideally this would parse the TCP window size option from the SYN or
SYN|ACK packet, but for now we just assume the window size is 64 kB.
Previously we'd allocate buffers when sending packets. This patch
avoids these allocations by using the NetworkAdapter's packet queue.
At the same time this also avoids copying partially constructed
packets in order to prepend Ethernet and/or IPv4 headers. It also
properly truncates UDP and raw IP packets.
This makes splitters stand out visually so you can actually spot them.
Before this, you had to guess/know where they were, which was weird.
The look of the knurling is the same as GUI::ResizeCorner, to build on
the established visual language.
Instead of computing the grabbable areas on the fly in mouse event
handlers, we now figure out which parts of the splitter are grabbable
when something moves around, and then remember it.
This makes the code a lot easier to follow.
This removes `constexpr` from the interpolate method in Color.h and adds
`noexcept`. The roundf call cannot be constexpr on clang. This is the
only incompatibility preventing serenity from building under clang. I
tested this on OSX Big Sur 11.3 and 11.3.1, and everything works with
this change.
Since the introduction of multi-select, we have had both `on_selection`
and `on_selection_change`, the latter of which was only invoked when a
change in selection came in through the model.
This removes `AbstractView::on_selection` and replaces it usage with
the more explicit `on_selection_change` everywhere.
Models that contain UV co-ordinates are now supported,
and will display with a texture wrapped around it, provided
a `bmp` with the same name as the object is in the same
directory as the 3D Model.
The software rasterizer now samples a texture passed to us from the
GL context. This is currently a bit of a hack, as we should be
scanning from a list of texture units and checking if they are
enabled. For now, this at least gives some visual confirmation
that texturing is working as it should
