All programs that have a CEventLoop now allow local socket connections
via /tmp/rpc.PID and will dump a serialized JSON array of all the live
CObjects in the program onto connecting sockets.
Also added a small /bin/rpcdump tool that connects to an RPC socket and
produces a raw dump of the JSON that comes out.
It is now possible to unmount file systems from the VFS via `umount`.
It works via looking up the `fsid` of the filesystem from the `Inode`'s
metatdata so I'm not sure how fragile it is. It seems to work for now
though as something to get us going.
You can now set a GTableCellPaintingDelegate per column in GTableView.
For columns with a painting delegate set, the view will defer to the
delegate for painting each cell in that column.
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().
