Convert the output names specified in the "output" and "tray_output"
fields in bar blocks in i3's configuration to the referred output's
primary name. This allows specifying names other than the primary
output's name in the given fields without changing the IPC protocol.
In addition to the name of the monitor itself (which is still used as
the i3 output's primary name), register RandR output names associated
with the RandR monitor as alternative i3 output names.
Currently, only one name is ever added, and only the first name is
ever accessed; actually using the capability to store and access
multiple names comes in the following commits.
Currently simply returns output->name, but this will make it easier to
change how output names are stored in the following commits.
Also replace reading output->name with invocations of
output_primary_name. Code which writes output->name is unchanged. Done
using a mostly mechanical replacement of output->name to
output_primary_name(output).
- Promote the "How to build?" sub-section to a top-level
section ("Building i3")
- Convert the "Introduction" sub-section as the intro to the remaining
contents of the "Using git / sending patches" section
- Keep "Which branch to use?" as a level-3 sub-section, thus making it
a sub-section of what used to be the "Introduction" sub-section.
The test runs `xrandr setmonitor`, which will otherwise affect any test
scheduled after 533-randr15.t, causing flakyness in t/217-NET_CURRENT_DESKTOP.t
for example.
The code in handle_signal() wasn't clearing the struct sigaction before passing it to sigaction().
This meant that we would block a random set of signals while executing the default handler, or jump to the uninitialized __sa_sigaction__ (instead of sa_handler).
Initialize properly as we do in setup_signal_handler().
If conn == NULL or display == NULL, init_dpi() jumps to init_dpi_end
before (declaring and) initializing resource. In init_dpi_end, there
is a free(resource) call conditionally on resource != NULL, so this
may lead to a bogus free. Found by clang -Wsometimes-uninitialized.
This fixes the following issue when having an error early in the config file:
