To protect your system and ghostty from misbehaving programs that launch
too many processes for the system to handle (e.g. like a fork bomb),
this implements an option to limit the number of processes that can be
started in a surface.
A fork bomb for example or other misbehaving program would then only
take down one surface and not the entire system.
Side node:
If I am right in issue #2084, this feature does not actually work on a
per surface basis but on all surfaces. If this is the case, it could
probably be fixed together. Chances are, that I am wrong though 😉
Further improvements that could be done:
- unify way to set cgroup attributes
- set sane default: 10% of system max?
These sequences were implemented:
CSI 14 t - report the text area size in pixels
CSI 16 t - report the cell size in pixels
CSI 18 t - report the text area size in cells
CSI 21 t - report the window title
These sequences were not implemented because they manuipulate the window
state in ways that we do not want.
CSI 1 t
CSI 2 t
CSI 3 ; x ; y t
CSI 4 ; height ; width ; t
CSI 5 t
CSI 6 t
CSI 7 t
CSI 8 ; height ; width ; t
CSI 9 ; 0 t
CSI 9 ; 1 t
CSI 9 ; 2 t
CSI 9 ; 3 t
CSI 10 ; 0 t
CSI 10 ; 1 t
CSI 10 ; 2 t
CSI 24 t
These sequences were not implemented because they do not make sense in
a Wayland context:
CSI 11 t
CSI 13 t
CSI 14 ; 2 t
These sequences were not implemented because they provide information
about the screen that is unnecessary.
CSI 15 t
CSI 19 t
These sequences were not implemeted because Ghostty does not maintain an
icon title for windows.
CSI 20 t
CSI 22 ; 0 t
CSI 22 ; 1 t
CSI 23 ; 0 t
CSI 23 ; 1 t
These sequences were not implemented because of the additional
complexity of maintaining a stack of window titles.
CSI 22 ; 2 t
CSI 23 ; 2 t
The case where the split if fully opaque (`unfocused-split-opacity = 1.0`) should result in the overlay being fully transparent (`opacity: 0.0`).
This would be consistent with how this is implemented in the macos app:
dcc492f19b/macos/Sources/Ghostty/Ghostty.Config.swift (L302)
The case when `quit-after-last-window-closed=true` and
`quit-after-last-window-closed-delay=null` was broken because control
gets stuck inside `g_main_context_iteration` and never returns to our
code. In that case add a 0ms timer that will return control flow from
GLib back to our code so that we can quit.
Fixes#2039
Instead of "polling" to see if a quit timer has expired, start a single
timer that expires after the confiugred delay when no more surfaces are
open. That timer can be cancelled if necessary.
This patch fixes#2010 by implementing `quit-after-last-window-closed`
for the GTK apprt. It also adds the ability for the GTK apprt to exit
after a delay once all surfaces have been closed and adds the ability to
start Ghostty without opening an initial window.
Left a FIXME where the "Copy" button action is disabled.
Though very hackish this was the best way I found to do this currently.
Disable sensitivity on the button didn't do anything and trying to
remove the button altogether like on macOS, causes the menu to become
really buggy. Either by the context menu turning into a scrollable list
or by it becoming really janky and showing the user pre-update UI.
In b7699b9a, mouse shape functionality was moved from the GL area widget
to the overlay that was newly created for the URL target information
that was included as part of #1928. This seems to have the side effect
of causing the pointer shape to revert to the default shape (here, the
basic arrow pointer) when dragging the mouse during selections.
This moves it back to the GL area, which seems to correct this. It
doesn't seem to need to be added to both - everything seems to function
correctly when a link is moused over, and then selection is made down to
the overlay area (not that this scenario is very likely, though).
When a split is created from a menu action, the focus is lost before the
split is made which prevents the surface from having the
unfocused_widget. Move the logic to add the unfocused_widget to the
overlay to an exported function which is called when the split is
created.
