sys$waitid() takes an explicit description of whether it's waiting for a single
process with the given PID, all of the children, a group, etc., and returns its
info as a siginfo_t.
It also doesn't automatically imply WEXITED, which clears up the confusion in
the kernel.
Notice that we are calculating release time according to the level when
the note is turned off rather than the sustain level. Naively using the
sustain level gives very long release times if you turn the note off
during attack, whereas this deterministically gives the same release
time.
1. Make decay sample-granular rather than buffer-granular
You only have ~43 buffers per second which can make a jagged signal.
2. Calculate decay in milliseconds
Decay is supposed to be a time value.
I say "phony" because it's not actually playing the same frequency
twice, it's just playing the same frequency at a higher volume. We can
properly implement this later but at the moment it'll get in the way of
our ADSR implementation.
Now you can change the defaults in AudioEngine and not be totally
confused.
1. The default for m_octave_knob was actually upside-down.
2. The default for m_decay_knob wasn't respecting AudioEngine.
3. The default for m_delay_knob wasn't respecting AudioEngine.
We add this feature together with the VMWareBackdoor class.
VMWareBackdoor class is responsible for enabling the vmmouse, and then
controlling it from the PS2 mouse IRQ handler.
On my system (Void Linux) the root user has a default umask of 0077,
causing files and directories in the disk image to have zero group and
world permissions.
For memory profiles, we now keep track of which allocations are still
live at the end of the selected timeline range and only show those.
This is really cool, I have to admit. :^)
"perfcore" is the file that the kernel generates after a process that
was recording performance events has exited.
This patch teaches ProfileViewer how to load (and symbolicate!) those
files so that we can look at them. This will need a bunch more work
to make it truly useful.
This patch introduces sys$perf_event() with two event types:
- PERF_EVENT_MALLOC
- PERF_EVENT_FREE
After the first call to sys$perf_event(), a process will begin keeping
these events in a buffer. When the process dies, that buffer will be
written out to "perfcore" in the current directory unless that filename
is already taken.
This is probably not the best way to do this, but it's a start and will
make it possible to start doing memory allocation profiling. :^)
I've been wanting to do this for a long time. It's time we start being
consistent about how this stuff works.
The new convention is:
- "LibFoo" is a userspace library that provides the "Foo" namespace.
That's it :^) This was pretty tedious to convert and I didn't even
start on LibGUI yet. But it's coming up next.
This commit implements the `useradd` utility that is found on most,
if not all *NIX systems. It allows the root user to add new users
to the password file found in `/etc/passwd`, thereby making
it easier to manipulate the file.
Previously, `fopen()` didn't contain an implementation for the
append modes, even though the Kernel supports it via `O_APPEND`.
This patch rectifies that by implementing them so an assert is
no longer thrown.
There are some headers in libc that require us to have definitions,
such as `FILE` available to us (such as in `pwd.h`). It is bad
practice to include the entirety of `stdio.h`, so it makes more
sense to put `FILE` into it's own header.
Unparented GActions are still parented to the application like before,
making them globally available.
This makes it possible to have actions that work whenever a specific
window is active, no matter which widget is currently focused. :^)
