amazing this didn't blow up before. missing e_ in front ad the macro
should have transformed this to wrap the e version of this func...
clang warning pointed this out. a real bug waiting to happen.
@fix
this means no leaked fd's between restarts too. cleaner. it also
encorces "die with parent" for enlightenment_start too as another
bonus in addition to its own fifo handling for singleton access per uid.
WARNING: you need to log out and log back in since the "protocol
expectations" (what exit codes do what and what parent and child
process are responsible for) changed so to get them both back in sync
you need to log out and in.
no improvements like per screen brightness... but a straight
conversion to the new system tool which simplifies e backlight a lot.
it'd be betetr to use the new system also to read backlight value and
list lightss etc ... but for now this is a good first stage.
so e has had a bit of a mess of setuid root tools to do things that
are essential to maintaing a functioning desktop/laptop/tablet/phone
like device like shutting it down or suspending or sqizzling the cpu
governor or messing with the backlight or... you get the idea.
this has been spread around enlightenment_sys and other special
purpose tools. this now unifies it into a single "always there"
enlightenment_system backend setuid root slave process whose job it is
to do all these things via a stdio protocol in an organized way. this
means latency to do something is lower, but at the expense of
consuming ram and a lurking process. unfortunately the lurking will be
needed soon when i add ddc support to make it even vaguely efficient,
so it's a cost i guess we have to pay now. we'll need this in future
as well for some stats collection and more.
still need to port existing code to use this instead of the existing stuff,
and then remove of the old stuff.
when you select save from shot now it always saves to your user shots
dir (~/.e/e/shots) and then opens up this fir for you to browse/see/dnd
out of etc. etc. for easier quick and fast access to what you just
saved. also you keep a history of your shots (you do get to clean it up
yourself when you save... no auto-cleaning - i decided not to bother
as realistically it's just more config to swizzle and mystery deletion
of files that some user has to figure out how and why it happens and
where to go change the config - just delete the ones you don't want
anymore - simple and easy.)
