CTCP requests are client-to-client messages that are sent as either
PRIVMSG (for requests) or NOTICE (for responses) and wrapped in ASCII
character 0x01 on both sides.
This patch implements responding to the very common VERSION and PING
requests. We always get a VERSION request from freenode when connecting
there, for instance. :^)
Right now if we encounter an unknown character, printf (and its related
functions) fail in a really bad way, where they forget to pull things off
the stack. This usually leads to a crash somewhere else, which is hard to
debug.
This patch makes printf abort as soon as it encounters a formatting
character that it can't handle. This is not the optimal solution, but it
is an improvement for debugging.
This solves an issue in GScrollableWidget where hiding one of the two
scrollbars needs to trigger a relayout since the other one should grow
into the "shared space" in the bottom right corner.
A GWidget can now override custom_layout() which will be called at any
time we would normally delegate work to the GLayout, e.g on resize
or child visibility changes, size policy changes, etc.
There were various little mistakes in the width calculations used by
the line-wrapping layout code.
With this patch, we should no longer see the horizontal scrollbar get
enabled with line-wrapping enabled. I will hide the scrollbar in a
separate patch.
text_position_at() was returning -1 if the position wasn't in
the bounds of a visual line. Now if the position is past the last
line, we simply return the last line index instead of -1.
Fixes#502.
You can now munmap() a part of a region. The kernel will then create
one or two new regions around the "hole" and re-map them using the same
physical pages as before.
This goes towards fixing #175, but not all the way since we don't yet
do munmap() across multiple mappings.
Motor Enable now selects the correct drive. The ternary
operations were backwards. QEMU doesn't care (obviously) but
on a real PC, the drive doesn't actually ever get selected...
It's now possible to add a GMenu as a submenu of another GMenu.
Simply use the GMenu::add_submenu(NonnullOwnPtr<GMenu>) API :^)
The WindowServer now keeps track of a stack of open menus rather than
just one "current menu". This code needs a bit more work, but the basic
functionality is now here!
When we update our content size, the width & height is now calculated
from the visual line rect size. Also now after we recompute all visual
lines, if the total height is different, we re-update the content size.
