Port sighandler to tree-branch
blocks SIGPIPE. Unfortunatelly blocked signal set is preserved accross
execve()s, so any program executed by i3 inherited blocked SIGPIPE signal.
This leads to courious effects when pipe writer does not terminate after
exiting pipe reader.
Simple reproducer is to spawn a new xterm by a key shortcut and then run this
command there:
$ perl -e 'print $SIG{PIPE}, qq{\n}'
IGNORE

If input focus is set by the window manager, it is not necessary to send
WM_TAKE_FOCUS because it has already taken focus.

Both setting input focus and sending WM_TAKE_FOCUS is effectively
setting focus on the window twice which is certainly against the spirit
of the spec, if not the letter.
fixes#1167
Add and update the _NET_CLIENT_LIST property on the root window to
better comply with ewmh standards.
Information on this property can be found here:
http://standards.freedesktop.org/wm-spec/latest/ar01s03.html
> These arrays contain all X Windows managed by the Window Manager.
> _NET_CLIENT_LIST has initial mapping order, starting with the oldest window.
fixes#1099
Otherwise, we read random garbage. Found by the testsuite due to
t/185-scratchpad.t failing because a window was incorrectly recognized
as a floating window.
According to 4.1.7 of the iccm spec
http://tronche.com/gui/x/icccm/sec-4.html#s-4.1.7
> Windows with the atom WM_TAKE_FOCUS in their WM_PROTOCOLS property may
> receive a ClientMessage event from the window manager (as described in
> section 4.2.8) with WM_TAKE_FOCUS in its data[0] field and a valid
> timestamp (i.e. not CurrentTime ) in its data[1] field.
Adds the timestamp parameter to send_take_focus to avoid the dangerous
use of a global variable.
This memory leak is related to matching on con_id or matching when the
container has a null window. In that case, windows that do not match
would leak the owindow struct.
This memory leak is associated with matching by a criteria that uses a
regular expression. Without freeing a regex before calling match_init,
it will definitely be lost.
BAIL_OUT produces a friendlier message explaining why the tests cannot
continue on the command line. `die` produces a cryptic message that some
test failed for some reason.
cmd_resize does not implement a method to resize dock clients.
A command like `[instance=".*"] resize grow width 160 px or 16 ppt`
when a dock client matched would crash i3.
fixes#1201
The suppression file makes valgrind output more readable by hiding
reports of memory leaks for GObject-related initialization functions in
Pango and Cairo.
Add a link to the new JavaScript, Python, and Lua ipc libraries.
Add notice that the older Python libraries are not maintained.
Sort the list alphabetically.
Windows that match the following criteria are floated by default:
- dialog, utility, toolbar, or splash windows,
- modal windows, or
- windows that have specified equal minimum and maximum size.

The function ipc_recv_message in libi3 allocates memory to the location
of the `message` reply in src/ipc_receive_message.c with malloc and must
be freed.
This memory leak was found using valgrind.
Rename `get_binding` to `get_keyboard_binding` and ensure that this
function only accesses bindings of type B_KEYBOARD. Other types of
bindings (e.g. mouse bindings) will be accessed by a different function.
This patch fixes ticket #1168 to extend the window IPC event mechanism
to send IPC events for window focus and title changes. The newly added
window events use the same format as the already established "new"
event.
Specifically this patch:
* Moves the ipc_send_window_event() function from src/manage.c into
src/ipc.c and adds an argument for the change property of the event
* Updates src/manage.c to use the new function signature. To ensure
that the "new" event does not send the same event data as the
"focus" event, setting focus now happens after the "new" event
has been sent
* Adds IPC focus event notification to src/x.c. To workaround a problem
during window close when accessing the window name, a function has been
added to query whether a window is actually attached to its parent. To
avoid obsolete focus notification, a new field has been added to keep
track of the focus without any interference by the click handling
* Adds IPC title event notification to src/handlers.c. To avoid
obsolete title notification, a function has been added to determine
whether a window title has actually changed
* Updates the IPC documentation to include the new events
* Updates testcases/t/205-ipc-windows.t to include the "focus" event
in order to ensure the correct event sequence
* Adds two new unit tests, b/testcases/t/219-ipc-window-focus.t and
b/testcases/t/220-ipc-window-title.t to ensure proper "focus" and
"title" events
To be honest, I’m not entirely sure where the race condition originates
from, but when making sure that there are no pending events
(which is what sync_with_i3 accomplishes) before warping the pointer, we
have less flaky testsuite runs.
closes#1189
Wait for the child process to exit on its own before freeing
watcher-related resources.
i3bar shows the last received status line until the process exits.
Fixes a race condition where the termination signal was sometimes not
received to display a meaningful error message.
This hopefully increases the reliability of the test. Empty containers
created by “open” sometimes get spurious UnmapNotify events, and in at
least one run, this test failed because of such an event.
The X11 protocol description states:
The window the event is reported with respect to is called the event
window. The event window is found by starting with the source window
and looking up the hierarchy for the first window on which any client
has selected interest in the event.
For the case of urxvt with URxvt.internalBorder > 0, urxvt sets up a
subwindow for its actual contents that is placed “in the middle” of the
urxvt window. In terms of the X11 protocol, the source window is urxvt’s
window, but urxvt does not select ButtonPress events for that.
Therefore, X11 will go up in the hierarchy and deliver the event to i3
for i3’s window decoration, even though this was not actually a click on
the decoration, but into the managed window.
Therefore, we check whether child != XCB_NONE for clicks on window
decorations and then handle them as a click inside the window.
