Ryan Dwyer e6829c5991 Move unsetting of view->surface into view_unmap 2018-06-27 17:54:57 +10:00
Ryan Dwyer 8773ed3970 Fix memleak in container_get_box
Rather than allocate a structure and expect callers to free it, take a
pointer to an existing struct as an argument.

This function is no longer called anywhere though.

Dominique Martinet 6856866a61 layer_shell: order destroying before sway_output
Both sway_output and sway_layer_shell listen to wlr's output destroy event,
but sway_layer_shell needs to access into sway_output's data strucure and needs
to be destroyed first.

Resolve this by making sway_layer_shell listen to a new event that happens at
start of sway_output's destroy handler

Ryan Dwyer a7b3f29292 Remove incorrect assertion and supporting code
Children can exist when destroying a container, such as when destroying
the last output. Sway is not terminating in that case.

Ryan Dwyer 93696b78ec Fix crash when closing output window from outer session
Emitting the close event needs to happen before
container_output_destroy, because container_output_destroy sets the
sway_output to NULL and sway_output is used in IPC.
2018-06-26 20:14:58 +10:00
Ryan Dwyer 834805f5e2 Fix crash when disconnecting output
We were freeing the sway_output immediately upon disconnect which left
a dangling pointer in the output's container. It then tried to use the
pointer when the container is freed.

We don't need to store the sway_output in an output's container which is
destroying, so the fix is to set the pointer to NULL and remove the use
in container_free.

Also added an arrange when the output is disconnected for good measure.

Dominique Martinet c9be014557 xdg_shell: make view floating if a parent has been set
Prompts e.g. authentication request from firefox-wayland ought to be
floating.

This is a bit coarse but just fixed size is not enough, here is what
firefox does:
[1285461.363]  -> xdg_wm_base@18.get_xdg_surface(new id xdg_surface@68, wl_surface@71)
[1285461.508]  -> xdg_surface@68.get_toplevel(new id xdg_toplevel@67)
[1285461.571]  -> xdg_toplevel@67.set_parent(xdg_toplevel@37)
[1285461.630]  -> xdg_toplevel@67.set_title("Authentication Required")
[1285461.736]  -> xdg_toplevel@67.set_app_id("firefox")
...
[1285476.549] xdg_toplevel@67.configure(0, 0, array)
...
[1285502.080]  -> xdg_toplevel@67.set_min_size(299, 187)
[1285502.140]  -> xdg_toplevel@67.set_max_size(1920, 32767)

This can also be observed with e.g. the open window of gedit
(gedit->open->other documents)

Ryan Dwyer 9b15e81cff Fix potential crash when fullscreen view unmaps
It happened when a view is a grandchild or deeper of the workspace, is
fullscreen, and unmaps. The workspace would not be included in the
transaction and its pointer to the fullscreen view was left dangling.

Ryan Dwyer b864ac0149 Fix crash when unmapping a view with reapable parents
container_destroy was calling container_reap_empty, which calls
container_destroy and so on. Eventually the original container_destroy
would return a NULL pointer to the caller which caused a crash.

This also fixes an arrange on the wrong container when moving views in
and out of stacks.

bugfix: avoid access after free
if src is NULL due to a previous error we cannot use it in the command
result string.

Moreover if `src` points to `p.we_wordv[0]` we cannot use it after
`wordfree(&p)` in the command result string.

Bonus feature: If there was an error accessing the file, the string
rapresentation of the error is now included in the command result
string.

Tobias Blass a5c091e302 Perform (partial) server initialization before dropping privileges.
Some operations during backend creation (e.g. becoming DRM master)
require CAP_SYS_ADMIN privileges. At this point, sway has dropped them
already, though. This patch splits the privileged part of server_init
into its own function and calls it before dropping its privileges.
This fixes the bug with minimal security implications.
