Fixes for undefined behaviour on signed shift
Change literal 1 to unsigned to allow safe bitshift of 31.
Caught by cppcheck.
Make 0xFF unsigned to prevent a left shift into signed bit.

Now clicks begin at the start of the "actual" block, offsets and
separators don't trigger click events. The width property is now just
the width of the block, including border.
Fixes#3380.
This fixes a new warning from GCC 8.1, -Wstringop-truncation:
https://gcc.gnu.org/gcc-8/changes.htmlhttps://gcc.gnu.org/onlinedocs/gcc-8.1.0/gcc/Warning-Options.html#index-Wstringop-truncation
Replacing with memcpy is what gcc suggests:
> As another example, the following call to strncpy results in copying
> to d just the characters preceding the terminating NUL, without
> appending the NUL to the end. Assuming the result of strncpy is
> necessarily a NUL-terminated string is a common mistake, and so the
> call is diagnosed. To avoid the warning when the result is not
> expected to be NUL-terminated, call memcpy instead.
> void copy (char *d, const char *s)
> {
> strncpy (d, s, strlen (s));

When i3bar is called with the -V flag but there is no 'verbose yes'
directive in the bar {} config, the verbosity config value is reset.
This will introduce the opposite, negligible issue: you can't disable
i3bar's verbosity by deleting the 'verbose yes' directive in the bar {}
config. To fix this we would need an enum for config.verbose.
Closes#3220.
i3bar’s X11 output is not what our testcases are testing — the state
manipulations which i3bar triggers via IPC messages to i3 are what we are
interested in.
Add support for relative coordinates in i3bar click events
Rename {x,y}_rel to relative_{x,y}
Update i3bar-protocol doc to mention the added fields in click events
i3bar's handle_button is modified to also handle XCB_BUTTON_RELEASE
events. During these button release events, only custom commands are
checked to avoid sending multiple workspace ipc messages.
The way this patch is implemented will allow to assign a custom command
for both the press and release of the same button:
bar {
...
bindsym buttonX exec command1
bindsym --release buttonX exec command2
}
Fixes#3068.
In i3bar/src/config.c we compare string lengths agains magic numbers.
This change replaces those numbers with the lengths of the strings they
represent.
Previously, we used ev_check watchers, which are executed at the beginning of an
event loop iteration.
This was problematic if one of the handlers happened to fill the XCB event
queue, e.g. by reading a reply from X11 and an event happened in the meantime.
In that situation, we would hand control to the event loop, entirely ignoring
the pending event. This would manifest itself as a 1-minute hang,
reproducible (sometimes) in the i3 testsuite.
issue #2790 describes an instance of this issue in i3bar, and we fixed that by
changing the watcher priority to run last. Handling events in xcb_prepare_cb has
the same effect, as ev_prepare watchers are run just before the event loop goes
to sleep.
All other message types are verbs, only our first-ever message COMMAND wasn’t.
While we’re here, also change the message type dictionary into a table with
clickable links to the corresponding reply type.
Authors of downstream IPC libraries are encouraged to keep the old name around
so as to not break existing code, but mark it as deprecated.
As of 2f0f8b1, i3bar will properly clean up on output change events.
However, this requires us to query the workspaces again to avoid a
display error in i3bar.

Thanks to @psychon for pointing this out during the review of PR #2624.
This commit extends this change to all other occurences of Expose events
within i3.
Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
Some tray clients such as VLC use override_redirect on their tray window. As per
specification this means i3bar won't receive a ConfigureRequest, but instead a
ResizeRequest will be triggered. If not selected, the X server will simply confirm
the request which leads to a broken tray window size.
This commit selects and handles the event just like a configure request is handled.
fixes#2494
When I3SOCK is present, socket_path might be a pointer to an
environment variable, which cannot be free'd in line 157. This
commit duplicates the string if I3SOCK is present, thus making
socket_path a free-able pointer again.
This commit removes an unnecessary fallback to the first output's name as
this name ("first") will only be used to see whether "tray_output none"
has been specified, anyway.
We also add documentation that clearly states when we want to initialize
the tray and when we don't want to do the same.
relates to #2220
This commit removes the code for falling back to the first available
output for the system tray if 'tray_output primary' has been specified
but there is no primary output (managed by this bar).
This fallback behavior was broken/unreachable because the tray
will never be initialized in this situation in the first place. Having
this dead code lead to a wrong assumption in #1855 and hence to
commit e2e7b70d00, which makes the
system tray not show up for many users when first installing i3.
Thanks to @rtlanceroad for reporting this issue.
fixes#2220
This allows "modifier none" (and "modifier off") for the bar config
in order to disable the modifier key altogether. This is useful
for users who use a different approach to hiding / showing the bar,
e.g., a custom keybind that involved multiple keys or scripts.
fixes#2208
