The plug-in unnecessary reopens the display, which is quite expensive operation. It results into 16 syscalls: socket(PF_LOCAL) -> connect(sun_path=@"/tmp/.X11-unix/X0"}) -> getpeername() -> uname() -> access(".Xauthority") -> open(".Xauthority") -> fstat() -> mmap() -> read() -> close() -> munmap() -> getsockname() -> fcntl(F_SETFD) -> fcntl(F_SETFL) -> shutdown() -> close() This is almost half of all the syscalls that we ought to execute for the plug-in to work. Now, considering the useful work and that "Locks" runs every 200 milliseconds, it gives us >300 syscalls (and a lot more wake-ups) per second. This commit fixes the reopening issue, effectively halving the CPU consumption (down to ~1%). The patch also makes it easier to implement event-driven indicators that will reduce the idle CPU consumption to 0. 2014-09-14T08:03:48Z Alexander Shabalin shabalyn.a@gmail.com 2014-09-07T18:24:00Z urn:sha1:e590f14593728b8afc2b77e8be356e5c06428107 * Batt * Bright * Cpu * Disk * MPD * Mem * MultiCpu * Net * Volume * Wireless 2014-09-14T08:03:48Z Alexander Shabalin shabalyn.a@gmail.com 2014-09-04T18:53:06Z urn:sha1:e8e4415b7eba49d2d6ddb18ab13b3151c9a787bd * DynamicString is an Int -> String which takes a value from 0..8 and produces a string with this value embedded. Usefull for replacing vbars with icons: an icon per one of 9 states. * API is similar to that of vbar. * Default parser of DynamicString produces a function of `i` to a string that replaces all occurences of "%%" with `show i` 2014-09-11T12:35:26Z Tony Morris tmorris@tmorris.net 2014-09-11T12:35:26Z urn:sha1:eb9f7a73677cc2bc872c3ea69f073faeefe6c989 2014-09-11T05:21:23Z Tony Morris tmorris@tmorris.net 2014-09-11T05:21:23Z urn:sha1:4ddfafe8904780ef599158525a7b4f52da7c6965
