This should fix build on systems where execinfo.h is present
but the APIs are implemented in a separate library - commonly
a case on the BSDs as well as on non-glibc libcs and so on.
pre-scale a bunch of resolutions for generated wallpaper files that
intersect with common resolution sizes so e will automatically load
the nearest resolution to be more efficient on load to only decode
what is needed. a bi-product is that e now has a wallapper gen
tool that is simpler than writing your own edc files... :)
@feature
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.
new feature - polkit auth agent support partly in core (need to have
the pam setuid root auth tool respond via dbus) and partly a module
(the agent dbus protocol handling and setup as well as auth gui). this
took me a while even with all the docs to work out how polkit works...
it was really fussy and its data structs are an extra pain in the butt
to craft with eldbus, but i managed it. not everything is supported
but the core basics are there and this can be built on.
right now the gui is really basic, but does the job.
still have a problem - cant work in wl drm/kms mode because e still
holds the ownership/lock on the console, but using full efl to draw
the alert and even blink it...
this drops xcb requirement too.
but is not explicitly linking against it. Previously this was not
discovered due to a wrong flag in elementaries pkgconfig. However - the
new .pc file of elementary does not contain dl anymore (as no library
_needs_ to link against it when using elm). So we need to link this here
explicitly
Differential Revision: https://phab.enlightenment.org/D7150
this should fix T6211 ensuring no drivers can cause a segfault at exit
time. this also happens to remove the enlightenment_sys -z option for
openbsd and unifies all the passwd checking into the single
enlightenment_ckpasswd binary util (that has ifdefs for openbsd,
freebsd and linux pam in it).
this simplifies code removing a mess of auth being done in multiple
places, removes special fork vs run 1 exe or a different exe in
different cases making it more maintainable. yes - this requires
enlightenment_ckpasswd to be setuid root, but it already was when it
was built.
@fix
e_start isnt really using evas atm - cserve2 env vars arent being set
so remove it - e_start can start a little faster with less linking...
good for startup time perhaps and mem footprint of e_start while it
babysits
