It can sometimes be difficult to tell from the debug.log and test stdout
which test was the last to run before the test runner hangs or exits the
QEMU instance unexpectedly.
Print out a start message before each test is executed, along with a
progress message indicating which test out of how many tests we're about
to run.
The previous version of this was pretty bad and caused a lot of
odd behevaiour to occur. We now abstract a lot of the allocation
behind a `template`d pool class that handles all of the memory
allocation.
The number of UHCI related files is starting to expand to the point
where it's best if we move this into their own subdirectory. It'll
also make it easier to manage when we decide to add some more
controller types (whenever that may be)
This patch prevents CppComprehensionEngine from endlessly looping when
there's a circular #include in the code.
We now keep track of the set of currently processed files, and will not
re-process a file if it already exists in this set.
When we're done with processing a file it is removed from this set.
The pragma once directive is not yet implemented, but regardless a
mechanism that prevents #include loops even in the absence of
pragma once is desired.
This brings `glGetFloatv` more inline with the other `glGet`
functions. We should prevent crashing in the driver as much as
possible and instead let the application deal with the generated
GL error.
Previously debug-kernel.sh wouldn't detect source if you launched the
script from the wrong path. By explicitly setting the name, source will
be loaded by gdb in all situations.
If a member is an empty class, the standard normally stats that it needs
to have a size of at least 1 byte in order to guarantee that the
addresses of distinct objects of the same type are always distinct.
However as of c++20, we can use [[no_unique_address]] to instruct the
compiler that if the member has an empty type, it may optimize it to
occupy no space.
Instead of constructing a String and converting that to a PropertyName
on the fly, we can just leverage CommonPropertyNames, add a couple more
and directly pass ready-to-use PropertyNames with pre-allocated Strings.
Otherwise, we emit a menu_item_left to the WindowServer client even
though the mouse never left the menu item (as is the case when a
disabled menu item is clicked).
Since we operate in screen space where y points down we need to reverse
what is considered clock wise and what is considered counter clockwise.
The rasterizer always expects triangles with a consistent winding order
thus swap 2 vertices if necessary to reverse the winding before passing
the triangle on to the rasterization stage.
The previous clipping implementation was problematic especially when
clipping against the near plane. Triangles are now correctly clipped
using homogenous coordinates against all frustum planes.
Texture coordinates and vertex colors are now correctly interpolated.
The earier implementation was just a placeholder.
GL_VERSION: The spec mandates the following format: x.y or x.y.z
optionally followed by text separated by space.
GL_EXTENSIONS: Return empty string. We do not support any extensions.
glTexCoord should behave like glColor. It only updates a gl context
variable that contains the current texture coordinates. The vertex is
only actually created once glVertex is called.
aplay would previously just retry a couple of times when the loader
encountered an error, even though there is a standard mechanism for
loaders to report errors. Now, aplay outputs these errors to the user
and exits.
FlacLoader initialized, but never used its resampler; this is now fixed
and all subframes are resampled before decorrelation occurs. FLAC files
with non-44100-Hz sample rates now play properly.
Floating-point ratios are inherently imprecise, and can lead to
unpredictable or nondeterministic behavior when resampling and expecting
a certain number of resulting samples. Therefore, the resampler now uses
integer ratios, with almost identical but fully predictable behavior.
This also introduces the reset() function that the FLAC loader will use
in the future.
Since readdir() actually gives us the file type, we don't have
to stat it again to know whether it's a directory! This means that
'find /' can process the majority of files without ever calling
stat() on them, simply by reading directories.
In addition, the TypeCommand (-t) can make use of this info too,
so, for instance, a 'find / -t d' does not need to stat anything
either.
This gives us a final huge speedup :^)
...in a few more places, at least.
find(1) is about to start relying on the reported types more or less
reflecting reality. This is especially relevant for magic symlinks
in ProcFS.
We have multiple commands that are implemented in terms of stat.
Let's cache the stat in FileData after we query it once.
This gives us another large speed-up :^)
While Core::DirIterator is nice C++ API, we want more low-level
control here. In particular, we want to open the directory using
openat(), to also not pay the cost of re-traversing the path
components we have already resolved previously.
This gives us another nice speedup :^)
Also, in the future commits this will allow us to make use of more
data from the returned struct dirent, to speed things up even further.
