f47945759b LibGUI: Make GTableModel a retainable object. 
It became clear that this class needs to support multiple owners.

41c744b3c8 Kernel: Don't panic if a call redirected to Device::open() has an error. 
Just pass the error to the user. I hit this when opening so many Terminal
windows that PTYMultiplexer::open() ran out of master/slave pairs.

6f966ca51d Kernel: Accepting sockets don't need to retain the client sockets. 
This is all taken care of by the respective FileDescriptors.
Before this patch, we were leaking every single socket, not great!

e48cbf3c8c Kernel: connect() should fail with EISCONN for already-connected sockets. 
Also make sure to reset the socket role if Socket::connect() fails.

4aa0ab4e08 Kernel: Fix race between accept() and connect(). 
We had a bug where an accepted socket would appear to be EOF/disconnected
on the accepting side until the connecting side had called attach_fd().

Fix this by adding a new SocketRole::Connecting state.

31d3616027 WindowServer: Don't crash when accept() fails, just log an error. 
This was easy to hit by opening enough windows to hit the max open file
descriptors limit. :^)

a02c945ef2 Kernel: DoubleBuffer can return early if read/write is called with !size. 2019-03-20 02:12:40 +01:00

1c423f7691 Terminal: Disable the semitransparent Terminal effect for now. 
It's cool and everything but the lag is annoying me while I'm trying to
get shit done. I'll definitely reenable it once it's been optimized.

0e4a1936ca LibC: Implement gethostbyname() by talking to the DNSLookupServer. 
We now talk to the lookup server over a local socket and it does the lookup
on our behalf. Including some retry logic, which is nice, because it seems
like DNS requests disappear in the ether pretty damn often where I am.

3ecfde193a GEventLoop: Quit the event loop on EOF from the WindowServer. 2019-03-20 01:10:52 +01:00

fe2fa4ac80 DNSLookupServer: Start working on a userspace DNS resolver. 
This doesn't have any server functionality just yet, but it does post
decent-looking DNS queries and parse the responses.

d0559c0e27 IRCClient: Scroll windows to bottom when new messages arrive. 
This will need some tweaking to feel truly good, but this is already
better than just staying at the top while messages come in.
 2019-03-19 03:09:51 +01:00

9551e2e4b5 LibGUI: Add GScrollableWidget::scroll_to_bottom/top(). 2019-03-19 03:09:21 +01:00

e15cc4509f LibGUI: More GInputBox refinements. 
Fix some GBoxLayout bugs to make the buttons in GInputBox line up better.
There are still some imperfections due to rounding errors.

46577a6948 GTextEditor: Fix invalidation glitches in single-line mode. 2019-03-19 02:45:49 +01:00

a0411f61f8 IRCClient: Make the IRCWindow input box look symmetrical. 2019-03-19 02:45:01 +01:00

31bc42c530 IRCClient: Ignore empty strings from the toolbar action input boxes. 2019-03-19 02:30:16 +01:00

c151b0370d IRCClient: Fix broken handling of RPL_WHOISIDLE. 2019-03-19 02:28:34 +01:00

f88e550998 LibGUI: More work on GInputBox. 
- If the GInputBox has a parent and the parent is a GWindow, center the
  input box window within the parent window. This looks quite nice.

- Stop processing events in a nested event loop immediately after it's
  been asked to quit.

- Fix GWidget::parent_widget() behavior for non-widget parents.

a6538feed1 LibGUI: Add GInputBox for getting a string from a modal dialog. 
Use this to implement some of the toolbar actions in IRCClient. :^)

b87c099535 WindowServer: Don't allow Logo+RMB to resize blocked-by-modal windows. 2019-03-19 01:40:41 +01:00
Andreas Kling
43304d2adf WindowServer: Add special treatment for modal windows. 
While a WSClientConnection has a modal window showing, non-modal windows
belonging to that client are not sent any events.

57ff293a51 LibGUI: Implement nested event loops to support dialog boxes. 
This patch adds a simple GMessageBox that can run in a nested event loop.
Here's how you use it:

    GMessageBox box("Message text here", "Message window title");
    int result = box.exec();

The next step is to make the WindowServer respect the modality flag of
these windows and prevent interaction with other windows in the same
process until the modal window has been closed.

55aa819077 IRCClient: Colorize some channel messages (joins, parts, topics) 2019-03-18 20:56:45 +01:00

794c81626e WindowServer: Cache the last two backing stores to make flipping faster. 
Instead of reattaching to the shared buffer on every flip, keep a reference
to the last seen backing store GraphicsBitmap. This way we can simply
swap the two last buffers when a flip happens.

This does increase memory consumption in apps that disable double-buffering
but I'll address that issue separately.

214b67defd AK: Add Vector::remove_first_matching(Callback). 
This is a nice little helper to remove one item based on a matching
callback without having to do iteration yourself.
 2019-03-18 20:51:40 +01:00

d7659ceebf IRCClient: Add support for a bunch of numerics, mostly WHOIS related. 2019-03-18 15:36:32 +01:00

9ad076178a GIODevice: Add a read_all() that returns a ByteBuffer with all we can read. 
Use this to implement file opening in TextEditor.
 2019-03-18 14:38:30 +01:00
Andreas Kling
8e3d0a23d5 LibGUI: Add GTCPSocket and base class GSocket (inherits from GIODevice.) 
And use these to do the line-by-line reading automagically instead of having
that logic in IRCClient. This will definitely come in handy.
 2019-03-18 14:09:58 +01:00
Andreas Kling
d466f2634d LibGUI: Add GTableModel::Role::ForegroundColor. 
This makes it possible to specify the text color for each table cell.
Use this to make the IRCClient show unread window list items in red.
 2019-03-18 04:54:07 +01:00
Andreas Kling
f4b8e4966f SharedGraphics: Add Color::to_string(). 
This generates a string in the format "rgba(%d, %d, %d, %d)".

c24d4b07db IPv4: Add simple pseudorandom ephemeral port allocators for TCP and UDP. 2019-03-18 04:03:44 +01:00

77a782a67e LibGUI: Don't crash if calling GClipboard::set_data() with a null string. 2019-03-18 02:59:08 +01:00
Andreas Kling
ce7017e1ec LibGUI: Add GFile and base class GIODevice. 
Working with the LibC API's is tedious, so let's add some comfy C++ API's.

ef05d8cbf6 AK: Use an OwnPtr for the VectorImpl. 
I don't know why it wasn't implemented this way already. This fixes a leak
in operator=(Vector&&) that we were hitting on Ext2FS write.
 2019-03-17 15:53:03 +01:00
Andreas Kling
4e451c1e92 Add client-side double buffering of window backing stores. 
This prevents flicker and looks rather good. The main downside is that
resizing gets even more sluggish. That's the price we pay for now.

2ac4f54724 WindowServer: Oops, the message loop should wake up for timers. 2019-03-17 02:46:42 +01:00

0f49b5e7be LibGUI: Ignore GWindow::update() with an empty rect. 2019-03-17 01:36:38 +01:00

01a2035ecf LibGUI: Don't nap in event loop if there are already queued events. 
This mirrors the WindowServer fix.
 2019-03-17 01:34:31 +01:00
Andreas Kling
d3dcb42227 WindowServer: Don't nap in the message loop if there's a queued message. 
This fixes a bug where clicking on a button would sometimes take a while
before showing up visually.
 2019-03-17 01:30:55 +01:00

1c6dfc3282 AK: Make ByteBuffer's copy() and wrap() take void*. 
This way we don't have to cast whatever we're passing to copy()/wrap().

5b0cbf547d Base: Some work on various icons. 2019-03-17 00:33:49 +01:00

ec8bffb06d LibGUI: Let GTextEditor deal with its horizontal padding internally. 
I originally wanted to have the padding concept in GScrollableWidget
but it's really finicky with the ruler and everything.
 2019-03-16 23:16:37 +01:00
Andreas Kling
78039ef057 TextEditor: Add actions for undo and redo. Not hooked up yet. 2019-03-16 23:16:11 +01:00
Andreas Kling
3854e752cb LibGUI: Make GTextEditor inherit from GScrollableWidget. 
This is quite nice, now we can share a ton of logic. :^)
 2019-03-16 16:54:51 +01:00
Andreas Kling
6fbabac460 LibGUI: Factor out scrolling logic from GTableView into a GScrollableWidget. 
This then becomes the base class for GTableView. I'd like to share as much
code as possible with GTextEditor and any other scrollable widgets.

dd5ca1940a AK: Hoist the assertion in Retainable::release() to RetainableBase. 
This means we don't have to generate a __PRETTY_FUNCTION__ symbol there
for each and every specialization.

3ebb5fbb87 AK: Remove custom allocator feature from Vector. 
This wasn't really used and generated a whole bunch of template bloat.
 2019-03-16 13:24:39 +01:00
Andreas Kling
5dd79736c5 Kernel: Remove the one client of Vector-with-custom-allocator. 
This was a silly experiment. If I want to save space here, I can do it in
one of many other ways.
