We're not equipped to deal with page faults during an IRQ handler,
so add an assertion so we can immediately tell what's wrong.
This is why profiling sometimes hangs the system -- walking the stack
of the profiled thread causes a page fault and things fall apart.
If we get an -ENOENT when resolving the target because of some part, that is not
the very last part, missing, we should just return the error instead of panicking
later :^)
To test:
$ mkdir /tmp/foo/
$ mv /tmp/foo/ /tmp/bar/

This is apparently a special case unlike any other, so let's handle it
directly in VFS::mkdir() instead of adding an alternative code path into
VFS::resolve_path().

The open menu stack is an internal data structure that outside classes
shouldn't really need to know about. Add MenuManager::has_open_menu()
so that the WindowManager can still know whether a menu is open or not.
We were failing to check if the current menu being set was already open.
This could result in multiple occurrences of the menu in the open menu stack.
When we close all menus descending from a menu we only delete the first
occurrence of a given menu from the menu stack (a fair assumption to make as
a menu should only be open once).
Because of this a menu (or multiple instances of it) could remain in the open
menu stack when it should actually be closed, leading to goofy behaviour.
Fixes#1238
There are various issues with this port that need to be fixed, but it's
at least possible to inspect and modify the SerenityOS repo if I clone
it into the disk image from the outside.
Very cool! :^)
This patch adds a crappy pread() just to get "git" working locally.
A proper version would be implemented in the kernel so that we don't
have to mess with the file descriptor's offset at all.
We were not repainting windows that were occluded at the time of the
theme changing. This patch adds a way to bypass occlusion testing when
invalidating window rects.
Fixes#1249.
Fixing out of bounds cursor in three different cases:
- when the buffer is empty
- when loading new files
- when entering values at the end of the buffer
