Add tests to check this feature
Apply config validation in config for simplicity
Note: if anything messes with the niceness (ie. it starts non-zero, or it's not the expected value during setup, we'll bail out)
The realpath(3) will fail if the target does not exist (internally
realpath will stat all the components of the link target path).
This is a problem in the case of sandbox applications where
the exe points to the absolute path *inside* the sandbox, e.g. to
/app/bin/<name> in the case of flatpak. For these cases realpath(3)
will then fail. Therefore use readlink(3) instead.
Add a inline helper function and a helper macro to be able to
automatically close file descriptors. Does nothing if the argument
is NULL or the pointed to integer is < 0.
On each gamemode_request call a new connection to d-bus is opened
but the reference was never release thus leaking the connection
and associated memory.
run_external_process() contained pipe file descriptors leaks (e.g. one
pipe end was never closed). Also the stdout might have been captured
incomplete, since only a single read() was performed on the pipe.
Furthermore should a child process try to write a larger amount of data
onto the pipe then it will become stuck, because the parent process
isn't consuming the data. Thus the timeout would trigger in these cases
although the child process does nothing wrong.
This commit changes the implementation to follow a select() based
approach that continually reads from the pipe, but discards data that
doesn't fit in the provided buffer.
Honor prefix for installing gamemoderun to properly work in cross
environment so it can be installed in e.g. /usr/x86_64-pc-linux-gnu/bin
instead of /usr/bin like it's already done for gamemoded.
The local variable 'bus' was shadowing the global 'bus' variable;
to not confuse the two, rename the local one. Also unref the local
bus, i.e. fix a small memory leak.
MAX_GOVERNOR_LENGTH is defined as PATH_MAX + 1, so when comparing
two variable, each of once size, use the smaller one, i.e. PATH_MAX.
Assert statically that MAX_GOVERNOR_LENGTH is larger then PATH_MAX
so copying a string to a MAX_GOVERNOR_LENGTH sized variable from a
PATH_MAX size variable will not truncate the string.
