954a0b8efe AK: Add a canonicalized_path() convenience function.
This is the same as calling FileSystemPath(foo).string(). The majority of
clients only care about canonicalizing a path, so let's have an easy way
to express that.

818a29c964 WSEventLoop: Move message processing into WSClientConnection
Tidier encapsulation than splitting messages between two classes.

7b75632e5c AK/LibAudio: Add stream read operators to AK::BufferStream, and use it in AWavLoader
At the same time, we allow chaining of streaming operators, and add a
way to check for partial reads (also used in WAV parsing).

e78097d140 SB16: Set "m_interrupted" to false before enabling IRQ's.
Otherwise, we might get interrupted before entering wait_for_irq() and then
resetting the flag again.

b2e502e533 Kernel: Add Thread::block_until(Condition).
Replace the class-based snooze alarm mechanism with a per-thread callback.
This makes it easy to block the current thread on an arbitrary condition:

    void SomeDevice::wait_for_irq() {
        m_interrupted = false;
        current->block_until([this] { return m_interrupted; });
    }
    void SomeDevice::handle_irq() {
        m_interrupted = true;
    }

Use this in the SB16 driver, and in NetworkTask :^)

3073ea7d84 Kernel: Add support for the WSTOPPED flag to the waitpid() syscall.
This makes waitpid() return when a child process is stopped via a signal.
Use this in Shell to catch stopped children and return control to the
command line. :^)

Fixes #298.

a634fab3c4 CObject: Add custom_event() virtual.
This way you can just override custom_event() to catch CCustomEvent instead
of having to filter the entire event stream with event(). :^)

1ecb7462b7 Piano: Use CEventLoop::wake() to trigger repaint from sound thread.
In order to repaint the GUI after the sound thread has produced some sweet
new waves, we post a CCustomEvent to the main thread's event loop and then
wake up that event loop via CEventLoop::wake().
2019-07-14 10:22:28 +02:00
Andreas Kling
17ee548bcd CEventLoop: Add wake(), a mechanism for waking up when blocked in select().
This patch generalizes the concept used in Piano to wake up the event loop
so it can react to something happening on a secondary thread.
Basically, there's a pipe who is always part of the file descriptor set we
pass to select(), and calling wake() simply writes a little to that pipe.

f1d6a37d5d LibCore: Add CThread, a simple thread abstraction object.
Currently this is only a simple wrapper around create_thread() that
remembers the thread ID of the spawned thread.

0a1bd03f1d WindowServer: Add a custom window type for Launcher
This keeps it out of the taskbar window list.
The stacking order is a little gnarly, but it seems to work OK still.

bee4544192 WSEventLoop: Treat invalid window types the same as unknown window types

ffa8cb668f AudioServer: Assorted infrastructure work
* Add a LibAudio, and move WAV file parsing there (via AWavFile and AWavLoader)
* Add CLocalSocket, and CSocket::connect() variant for local address types.
  We make some small use of this in WindowServer (as that's where we
  modelled it from), but don't get too invasive as this PR is already
  quite large, and the WS I/O is a bit carefully done
* Add an AClientConnection which will eventually be used to talk to
  AudioServer (and make use of it in Piano, though right now it really
  doesn't do anything except connect, using our new CLocalSocket...)

983245113a SB16: Write the correct DMA buffer offset for 16-bit samples.
Also switch to using single-cycle mode for now. It would be nice to add
support for auto-initialized mode but this works okay at the moment.

ec7b98f079 Piano: Take down the baseline "volume" from 3000 to 1800.
I have no idea what a good value for this would be. This seems to do better
when playing many notes at once.

02c3c737f6 SB16: IRQ handler should send 0xd5 to pause 16-bit playback.
We were sending 0xd0 to pause 8-bit playback. Not sure if this actually
makes any difference but it seems like the correct thing to do.
Also update 'm_interrupted' *after* handling things.

eec9666735 Piano: Use a secondary thread to write the audio stream.
This frees up the main thread to draw the GUI. The secondary thread uses
a pipe to trick the main thread's event loop to break out of select() and
update() the PianoWidget. :^)

302cae5c2f CEventLoop: When asked to exit the event loop, exit right away.
Don't process any more events. We already prepend the remaining events in
this loop to the outer loop if needed.

If there were any more events queued after the exit request, the iteration
code would make an invalid access into 'queued_events'.

Fixes #300.

debc587ce2 LibCore: Add CCustomEvent, a custom CEvent for arbitrary use.
For convenience it includes an int, and a void*. Interpretation of the
contents is up to the client.

Andreas Kling
d63b6e624e SB16: Send (sample count, less 1) to the DSP, not the number of bytes.
This worked fine when we were using 8-bit samples but broke on 16-bit.

Andreas Kling
781a28f3ed SB16: Switch to signed 16-bit 44100 Hz Mono by default.
We should switch to Stereo but I'm having some trouble with that locally..
Since we intend to mix everything through SoundServer, let's just put the
card into 16-bit mode right away.

c962c54610 Piano: Start working on a desktop piano.
The idea here is to implement a simple synhesizer that allows you to play
music with your keyboard. :^)

It's a huge hack currently but we can improve upon this.

85674aa498 WindowServer: Don't deliver the same mouse event twice.
We were sometimes delivering the same mouse event twice to the active input
window. This happened because we had already delivered it via the automatic
cursor tracking mechanism.

f79f3f6b8c IRCClient: Make the channel and query mappings case-insensitive.

"NickServ" without getting confused. :^)

9a7b638743 IRCClient: Process incoming NOTICE messages like PRIVMSG.
They should be handled slightly differently, but at least now we're doing

d9d13f2445 AK: Support case-insensitive HashMap<String, T>.
We achieve this by allowing you to specify custom traits for the key type.
For convenience, we also provide a CaseInsensitiveStringTraits for String.

b425de18cc LibGUI: Add an auto-repeat interval to GAbstractButton.

are pressing down the respective buttons. :^)
