This makes vector_push return a pointer to the pushed element.
It also allows the user to push a NULL pointer, which means allocating the
memory for the element but do not copy anything into it.
This lets us mark code as unreachable and signals the compiler that this
is the case with __builtin_unreachable().
We also mark DEBUG_FATAL as unreachable.
This, unlike the standard assert macro, is guaranteed to print the failed
assertion to our log file, and tests the assertion even with NDEBUG defined
so we can more easily catch failures in production binaries without crashing
the program.
The motivation of this is how MinGW handles assertion failures: it creates a
dialog window that the headless user will not be able to see, and blocks the
program from being restarted by the service. Since the failed assertion is
displayed in the dialog, it doesn't print anything to the log, making it
impossible to diagnose issues.
This is currently only implemented for Linux.
On Windows, ShellExecute should be used, but that should be done when it's
actually needed so it could be tested.
This replaces the scaled `destRect` with a version that uses doubles
correcting the rounding error that is causing a failure to properly
clear the black bar areas.
We implement nanotime by converting QueryPerformanceTimer output with
floating point arithmetic. This is necessary to preserve precision on
platforms where each tick is not an integer number of nanoseconds.
Furthermore, struct timespec is included C11 and appears to be supported
on Windows, so we no longer need to #ifdef it out.
This allows us to set a callback to read a value out before it's about
to be overwritten which can be useful for things like calculating a
running average.
This so called "enhanced" event logic is completely flawed and can never
work correctly, better to strip it out and put our faith in windows to
handle the events for us.
And yes, I am fully aware I wrote the utter trash in the first place :)
People often miss the warnings about invalid arguments in their command
line, this last minute patch attempts to address this by making
warnings, errors, fixme's and fatal errors stand out if stdout is a TTY.
Extensive profiling reveals that the glibc memcpy performs up to 2x
faster then the existing SIMD implementation that was in use here. This
patch also will copy large 1MB chunks if the pitch of the source and
destination match further increasing throughput.
This change adds an average function to time how long it takes the GPU
to copy and map the texture, and then uses this average to sleep for 80%
of this average lowering CPU usage and potentially decreasing lock
contention.
We previously used strstr, which can be prone to false positives when
the name of one extension is a substring of another extension.
This commit creates the helper function util_hasGLExt, which asserts
that the substring found in extension list is bounded by either spaces
or the beginning/end of the string.
Corners of table have '+' added, and adds new command line flag --rst-help,
which adds some extra formatting to the make it an rST compliant table for the
in-line docs.
Essentially, debug.h defines printTrace as an empty macro when the macro
ENABLE_BACKTRACE is not defined, breaking the compilation of crash.c.
Fixed by defining a private macro for debug.h only to avoid clashing.
The Wayland display server is getting unwieldy due to the sheer size.
To make it easier to edit in the future, I split it into many components
based on logical boundaries.
This allows buffers to be shared between different asynchronous operations.
Once all users no longer need the buffer, it will be freed.
The motivation for this is being able to stream Wayland clipboard data
asynchronously to multiple clients. The buffer should only be freed after
the clipboard has changed and all ongoing transfer completes.
