This patch adds the mprotect() syscall to allow changing the protection
flags for memory regions. We don't do any region splitting/merging yet,
so this only works on whole mmap() regions.
Added a "crash -r" flag to verify that we crash when you attempt to
write to read-only memory. :^)
This changes the behavior of the "is_checkable" flag on GAbstractButton
to only be about user interaction checkability. In other words, it now
only prevents the user from checking/unchecking the button, the code.
Now that we're bringing back the in-kernel virtual console, we should
move towards having a single implementation of terminal emulation.
This patch rips out the emulation code from the Terminal application
and turns it into the beginnings of LibVT.
The basic design idea is that users of VT::Terminal will implement and
provide a VT::TerminalClient subclass to handle presentation-specific
things. We'll need to iterate on this, but it's a start. :^)
Originally, it would stop being highlighted if the mouse was moved away from
it, even while in use. Now it will stay highlighted for the duration of
usage.
Now there's just CHttpRequest::set_url(URL), no need to specify the
host, port and path manually anymore.
Updated ChanViewer and Downloader for the API change.
Change the custom data massaging callback to take a const JsonObject&.
This will allow binding together data from multiple fields into one
output in the model. :^)
You can now call GTableView::set_size_columns_to_fit_content(true) and
the table columns will grow to fit the content. They will never shrink,
only grow.
This means I can spend a lot less time fidgeting with column widths :^)
These widgets can only display a single column from the underlying data
model, and it was previously hard-coded to use column 0. Now you can
use any column you like.
This ensures the pipe fds don't leak into child processes.
This manifested as the Shell (and all processes started
from the shell) having two mysterious FIFOs open. This
was happening because of the Terminal, which the shell
was spawned form, leaking its CEventLoop wake pipe fds.
In the userspace, this mimics the Linux pipe2() syscall;
in the kernel, the Process::sys$pipe() now always accepts
a flags argument, the no-argument pipe() syscall is now a
userspace wrapper over pipe2().
Fork the IPC Connection classes into Server:: and Client::ConnectionNG.
The new IPC messages are serialized very snugly instead of using the
same generic data structure for all messages.
Remove ASAPI.h since we now generate all of it from AudioServer.ipc :^)
- Add IEndpoint::handle(IMessage), a big switch table on message type.
handle() will return a response message for synchronous messages,
and return nullptr otherwise.
- Use i32 instead of int for everything
- Make IMessage::encode() const
- Make IEndpoint::decode_message() static, this allows template code to
decode messages without an endpoint instance on hand.
If the underlying variant type is a String, try to parse out a color
when to_color() is called.
This makes VisualBuilder apply the saved colors when loading forms.
This API was returning a "const char*" and it was unclear who took care
of the underlying memory. Returning a String makes that obvious.
Also make sure we close the /etc/passwd file when we're done with it.
It is now possible to mount ext2 `DiskDevice` devices under Serenity on
any folder in the root filesystem. Currently any user can do this with
any permissions. There's a fair amount of assumptions made here too,
that might not be too good, but can be worked on in the future. This is
a good start to allow more dynamic operation under the OS itself.
It is also currently impossible to unmount and such, and devices will
fail to mount in Linux as the FS 'needs to be cleaned'. I'll work on
getting `umount` done ASAP to rectify this (as well as working on less
assumption-making in the mount syscall. We don't want to just be able
to mount DiskDevices!). This could probably be fixed with some `-t`
flag or something similar.
