Quake now will build and run on Serenity. There are a few issues,
that'll stop you from playing currently, however, such as SDL
not having any keyboard input, as well as `printf_internal` throwing
an assertion over the `.` format specifier. However, the game launches
perfectly.
We were doing a temporary STI/CLI in MemoryManager::zero_page() to be
able to acquire the VMObject's lock before zeroing out a page.
This logic was inherited from the inode fault handler, where we need
to enable interrupts anyway, since we might need to interact with the
underlying storage device.
Zero-fill faults don't actually need to lock the VMObject, since they
are already guaranteed exclusivity by interrupts being disabled when
entering the fault handler.
This is different from inode faults, where a second thread can often
get an inode fault for the same exact page in the same VMObject before
the first fault handler has received a response from the disk.
This is why the lock exists in the first place, to prevent this race.
This fixes an intermittent crash in sys$execve() that was made much
more visible after I made userspace stacks lazily allocated.
Add text.startup to the .text block, add .ctors as well.
Use them in init.cpp to call global constructors after
gtd and idt init. That way any funky constructors should be ok.
Also defines some Itanium C++ ABI methods that probably shouldn't be,
but without them the linker gets very angry.
If the code ever actually tries to use __dso_handle or call
__cxa_atexit, there's bigger problems with the kernel.
Bit of a hack would be an understatement but hey. It works :)
The menubar bar wasn't being resized correctly, as the underlying Window
was never being resized when `DisplayProperties` was chaning the
resolution while the system was running. `m_window` now gets the
correct window size when it's been updated, so a reboot isn't required.
Make userspace stacks lazily allocated and allow them to grow up to
4 megabytes. This avoids a lot of silly crashes we were running into
with software expecting much larger stacks. :^)
When hovering over a C++ token that we have a man page for, we now show
the man page in a tooltip window.
This feels rather bulky at the moment, but the basic mechanism is quite
neat and just needs a bunch of tuning.
Previously, we did not properly restore termios settings
after running built-in commands. This has been fixed
by ensuring that we only change the termios settings
when we are forking a child process.
Add dedicated internal types for Int64 and UnsignedInt64. This makes it
a bit more straightforward to work with 64-bit numbers (instead of just
implicitly storing them as doubles.)
This seemed like a perfect fit for LibHTML. We can now style the IRC
channels and queries however we like with the power of HTML and CSS.
This patch doesn't do much in the way of styling, it just gets the
basic mechanism into place.
This is just a wrapper around strstr() for now. There are many better
ways to search for a string within a string, but I'm just adding a nice
API at the moment. :^)
Add the ability to both pass arguments to scripts with shebangs
(./script argument1 argument2) and to specify them in the shebang line
(#!/usr/local/bin/bash -x -e)
Fixes#585
With this patch, you can now assign the same GTextDocument to multiple
GTextEditor widgets via GTextEditor::set_document().
The editors have independent cursors and selection, but all changes
are shared, and immediately propagate to all editors.
This is very unoptimized and will do lots of unnecessary invalidation,
especially line re-wrapping and repainting over and over again.
This patch decouples GTextDocument and GTextDocumentLine from the line
wrapping functionality of GTextEditor.
This should basically make it possible to have multiple GTextEditors
editing the same GTextDocument. Of course, that will require a bit more
work since there's no paint invalidation yet.
The idea here is to decouple the document from the editor widget so you
could have multiple editors being views onto the same document.
This doesn't work yet, since the document and editor are coupled in
various ways still (including a per-line back-pointer to the editor.)
This patch adds Editor (subclass of GTextEditor) and EditorWrapper.
An EditorWrapper is a composite widget that adds a little statusbar
above an Editor widget. The statusbar is used for showing the filename
and the current cursor position. More things can definitely be added.
To get to the currently active editor, call current_editor().
You can also get to the current editor's wrapper by calling..
current_editor_wrapper(). Which editor is current is determined by
which was was last focused by the user.
This makes double-clicking on a C++ token in HackStudio select the
whole token, which is pretty nice. It's not perfect in all cases,
but a lot nicer than just expanding until we hit whitespace. :^)
This makes the backspace erase backwards until the next soft tab stop.
We currently always use 4 as the soft tab width, but I suppose we could
make it configurable at some point. :^)
