it seems some libc's or systes dont reset signal mask blocks on
exec(). this unblocks manuaklly jus befor eexec, moves blocking to
before fork and adds a "nuke all signal handlers" in the child process.
fixes T8797
in theory signal handlers could kick in after fork and before exec...
so block them until we're exec'd or exited so they don't change any
program state.
close all fd's starting at a given fd and then leving out an exception
list specially passed, if any. useful for fork+exec. this uses it in
efl's fork+exec paths.

This has been bugging me for some time but now we are triggering new errors internally
this is appearing to end users for problems they did not cause.
Additionally I was able to improve a couple of the errors by copying the
explanation from code comments into the error message.
Shorter error logs now too :)
efl.loop was still using legacy ecore_timer_* calls inside. of course
this is a big no-no if we are to allow multiple loops, so clean this
up and convert them to efl.loop.timers.
we really should have data inside the loop object, so begin moving it
one small thing at a time. this is the basics that will allow multiple
efl loops. make an eo efl object and class for fd handlers that is efl loop
bound make fd handlers really bound to their parent loop and not global as
well as have a nice class/obj. create an message queue per loop and
put legacy ecore events on top of it... and a lot more.
this is not 100% done, but it's a lot of the core and groundwork.
various ecore_timer_add(), ecore_diler_add() etc. need changes.
The following still need doing:
ecore_timer (internal usage for sure)
ecore_idler (internal usage for sure)
ecore_idle_enterer
ecore_idle_exiter
ecore_pollers? (is the new efl loop stuff ok?)
ecore_exe (fork/spawn from any thread and track exe from that thread?)
ecore_signal code
ecore_throttle (should we have a single global too? we have per loop)
ecore_app ? (should every loop be given its own argv/argc?)
Lots of internal ecore code uses/calls these legacy calls and we
should have efl loop replacements and/or use the ones we have
The following will bedifferently designed for loop to loop
control/messaging/ipc:
ecore_thread
ecore_pipe
for both ecore_exe_win32.c and ecore_exe_posix.c when the rare case
(basically almost never) that malloc fails for the exe read/err
buffers also set the data size to 0 so it doesn't lie with a NULL ptr
for data.
@fix
dont delete the obj during finalize... just retyurn NULL to fail.
fork() failed for me so i found this... ask not why fork failed... but
it did... and thus found this error handling case.
@fix
prctl allows us on some platforms to request a thread be woken up more
agressively e.g. due to a timeout bu setting timerslack. since we use
a dedicated thread just for vsync events, this is a very good idea to
ask the kernel to be as exact as possible for this thread as it only
wakes up once per frame (or should only) and accuracy is important. so
use this.
also improve prctl checks to be more explicit in configure.ac and use
these ifdefs in ecore exe too where prctl is used as well.
@feature
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
so i've been doing some debugging and having a mem debugger that
preloads and tracks allocs means you need locks, but locks can do
nasty things after forks + threads.... esp if threads held locks.
this allows mem debugging with preloads easily and doesn't muck things
up.
I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
This is the first step towards splitting it nicely. This fixes
compilation on windows (or so it seems from my testing) and takes out
all the platform specific code (posix included) out of the main source
file.
